SAN CARLOS, Calif .– (COMMERCIAL THREAD) – IncellDx, a precision medicine company, the newspaper announced today Frontiers in immunology published a study detailing a framework for understanding the potential mechanism and potential treatment of the post-acute sequelae of COVID-19 (PASC), also known as long-range COVID or long-range COVID.

“Recent analysis confirms that long COVID is impacting a significant number of people, and its prevalence could increase due to the emergence of the Omicron variant,” said Bruce Patterson, MD, CEO of InsellDx. “We know this is a very widespread and growing problem. What doctors lack is an understanding of the underlying cause of long COVID and a way to objectively diagnose and treat it. We believe this study provides additional evidence for a meaningful way forward for diagnosis and treatment. ”

In the study, Persistence of SARS CoV-2 S1 protein in CD16 + monocytes in post-acute sequelae of COVID-19 (PASC) for up to 15 months after infection, patients with previous COVID infection and persistent symptoms were found to have a distinct immunologic profile characterized by differentiated proportions of monocyte subsets. In the study, the presence of the SARS-CoV-2 S1 protein was investigated in 46 people. T-cell, B-cell and monocytic subsets have been analyzed both in patients with severe COVID-19 and in patients with post-acute COVID-19 sequelae (PASC). The levels of intermediate (CD14 +, CD16 +) and non-classical (CD14Lo, CD16 +) monocytes were significantly increased compared to healthy controls. None of the monocyte subsets were elevated in severe COVID-19 cases. In addition, the S1 subunit of the SARS-CoV-2 protein was present in unclassical monocytes in patients suspected of having PASC up to 16 months after initial infection. Monocytes, a type of white blood cell, are involved in adaptive immunity and play a key role in attacking viruses and other pathogens.

A previous article from IncellDx in Frontiers in immunology proposed the first model for diagnosing, indexing and tracking long COVIDs. In this study, Immune system-based prediction of severity and chronicity of COVID-19 decoded using machine learning, 224 individuals, including healthy controls and patients spanning the COVID-19 disease continuum, were assessed using machine learning for severity and chronic symptoms after initial infection. CCL5 / RANTES, IL-2, IL-4, CCL3, IL-6, IL-10, IFN-γ and VEGF were all significantly elevated in long-term COVID patients compared to healthy controls (P <0.001), while that GM-CSF and CCL4 were at significantly lower levels than healthy controls (P = 0.01). The data was analyzed to generate objective disease scores for PASC patients and severe COVID patients.

“The S1 protein is believed to cause inflammation, particularly vascular inflammation, which contributes to the hallmark symptoms of long COVID,” Patterson continued. “At IncellDx, we would like to congratulate all the groups who contributed to this critical publication showing the persistence of S1 protein in white blood cells months and now almost 2 years after SARS-CoV-2 infection in patients. suffering from long COVID or PASC. Critically, the data also shows the persistence of COVID RNA in these cells, but whole genome sequencing has revealed that they are RNA fragments unable to replicate. We are also excited to deploy Quantum Si’s single-molecule protein sequencing platform so that we can identify Omicron long-haul routes and determine whether mutated S1 proteins contribute to a different disease course in adults and patients. children in new variations such as Delta and Omicron.

Purvi Parikh, MD, an allergy and immunology specialist at NYU Langone Medical Center and co-founder of the Chronic COVID Treatment Center, said, “We knew the persistent inflammation was probably the cause of PASC and now with over evidence about the nature of inflammation, we can use targeted therapies to hopefully relieve these patients of this relentless disease. ”

Schools sticking to in-person learning scramble for subs Sun, 09 Jan 2022 17:54:33 +0000 HARTFORD, Connecticut – Principals, superintendents and counselors are replacing classrooms as the surge in coronavirus infections puts even more strain on schools that were already struggling with staff shortages.

Principals, superintendents and counselors are replacing classrooms as the surge in coronavirus infections puts even more strain on schools that were already struggling with staff shortages.

In Cincinnati, dozens of central office workers were dispatched last week to schools that were at risk of closing due to understaffing. Boston Schools Superintendent Brenda Cassellius tweeted that she was replacing a fifth-grade teacher.

San Francisco Superintendent Vince Matthews has called on all employees with educational credentials to take a course.

“This is the most difficult time in my 36 years as an educator,” Matthews said on a break after taking the sixth grade science teacher job on Thursday. “We are trying to educate students in the midst of a pandemic as the sands around us are constantly changing.”

Staff absences and the increase caused by the Omicron variant have driven some large districts including Atlanta, Detroit and Milwaukee. temporarily switch to virtual learning. Where schools keep the line on in-person learning, getting through the day required a holistic approach.

“It’s absolutely exhausting,” said history professor Deborah Schmidt, who was covering other courses during her planning period at McKinley Classical Leadership Academy in St. Louis. On Thursday, she was covering a physics class.

In a school year where teachers are asked to help students recover from the pandemic, some say they face overwhelming stress just trying to keep classes going.

“I had a friend who said to me, ‘You know, three weeks ago we were closing our doors again because of the school shootings, and now we are opening the window for COVID. “It’s really a bit too much,” said Meghan Hatch-Geary, an English teacher at Woodland Regional High School in Connecticut. “This year, trying to fix everything, trying to be everything for everyone, is getting more and more exhausting all the time.”

Union tensions were highest in Chicago, where classes have been canceled after the teachers’ union voted to deny in-person teaching, but union leaders in many school systems are calling for more flexibility on virtual learning, additional testing and other protections against the virus.

In New Haven, Connecticut, where hundreds of teachers had gone out every day last week, administrators helped cover classrooms. When her classroom assistant did not show up for work on Wednesday, special education teacher Jennifer Graves borrowed paraprofessionals from other classrooms for short periods to spend the day at Dr. Reginald Mayo School. Early Childhood School – a difficult and confusing arrangement for its young students. with disabilities.

“It’s very difficult to finish my lesson plans when someone doesn’t know your students, when someone isn’t used to working with students with disabilities,” Graves said. “Some students need sensory input, some students need to be spoon fed. It is therefore very difficult to train someone on site.

Even before infection rates took off during the holidays, many districts struggled to maintain their workforce, especially among substitutes and other lower-paying positions. As a result, teachers were dispersed for months, said Becky Pringle, chair of the National Education Assn.

“All of that extra burden and stress besides being worried about getting sick, besides being stressed like we all are after a two-year pandemic…” Pringle said in an interview.

Some administrators have already been helping classrooms and cafeterias replace sick and quarantined staff for months.

“We’re not in love with the circumstances, but we’re happy to do the job because the work makes sure we’re there for our kids,” said Mike Cornell, principal of the Hamburg Central School District in New York City. , who spent time in the cafeteria this fall stuffing straws into juice sachets and removing lids on chips to fill staffing gaps.

In San Francisco, 600 of the district’s 3,600 teachers were absent Thursday. Even with administrators, curriculum designers and teacher coaches, there weren’t enough substitutes to cover all the classrooms and some classes had to be combined, said Matthews, the superintendent.

Among the schools that went virtual last week due to a staff shortage was second-grade teacher Anna Tarka-DiNunzio’s school of about 200 students in Pittsburgh. Some taught their students while they were sick with the virus, said Tarka-DiNunzio, who was disappointed to hear some characterize staff shortages as the result of the arbitrary termination of teachers.

“It’s not just people calling. These are people who are sick or have sick family members, ”she said.

The pressures on schools could be even more difficult if large numbers of students were not themselves absent. In New Haven, teachers say classes were only half full.

Jonathan Berryman, a music teacher, said some of his students haven’t shown up for weeks. He is concerned about what this will mean for the performance goals set for students and their teachers.

“Before Omicron arrived, the navigation was pretty smooth. Now the ship has been rocked, ”he said. “We can make mid-year adjustments to our appraisal system. And some, I’m sure, wonder if we should even care about this element of academic advancement. ”

Graves, who is in her 12th year of teaching in New Haven, said she was grateful to the administrators who helped in the classrooms and the helpers who participated, but her students struggled to do so. faced with the lack of consistency in staff.

She was also frustrated by the rapidly changing health protocols and worried about her health and that of her extended family. Most of its young students cannot tolerate wearing masks for long periods of time, and many have been coughing lately.

“This is the most difficult year I have had,” she said.

While many arts organizations engage in continued anti-racism work and commit to more inclusive and diverse workplaces, few are moving forward with guidance and the collaborative professional community to foster the continuous learning and meaningful change. Launched on January 16, 2022, Coalition for Cultural Competence and Equity (C2EC), created by diversity strategist and former ballet dancer Theresa Ruth Howard, aims to create a learning community with the support, education and advocacy that organizations and their leaders need to reimagine and reshape culture and standards of classical arts.

Howard designed C2EC as a membership-based program comprised of leaders interested in working collaboratively with their peers to mainstream the core principles of inclusion, diversity, equity, anti-racism and anti-racism. cultural competence (IDEA and CC as part of Howard) in their organizations and the performing arts field in general. Attendees will have access to Howard’s Curriculum of Change, which addresses the needs of the field, from the pipeline to performance, from the boardroom to the box office and beyond. Individually and as a cohort, participants will also work towards their goals with Howard and his team of subject matter experts on topics such as history, organizational culture transformation, and more. Experts include Greg Jauncey (founder of the new human resources company Theater People, senior director of human resources and training at the Royal Opera House); Alejandra Valarino Boyer (Director of Programs and Partnerships, Seattle Opera); dance historian Linda Monich (Boston Conservatory at Berklee Associate Professor of Dance); Tina Fehlandt (Senior Lecturer in Dance at Princeton University, Marc Morris staging); and Dr Sarah L. Webb (Founder of the Global Colorism Healing Initiative).

Most importantly, C2EC will provide a measure of accountability that was lacking in many promises of change, by encouraging members to be transparent not only within the Coalition, but with their employees, board members, stakeholders. stakeholders, patrons and the public.

As a collaborative coalition, the voices of C2EC participants will shape and shape the work, support and services that Howard and his team will deliver. By design, C2EC is a malleable and adaptable entity to meet the emerging needs of members and the domain as they arise, while remaining true to the intent and mission. origin of the Coalition.

“I entered this job through the conversation about the lack of diversity in ballet,” Howard explains. “When I started working individually with performing arts organizations as a diversity strategist, it became clear that the culture and values ​​of the classical arts were part of the infrastructure that perpetuated the lack diversity, equity and inclusion. Therefore, the next phase of my work is to actively build the models of the new culture in the field of performing arts, a culture which has at its core the concept of citizenship, which implies a sense of personal responsibility and collective and humanity.C2EC will actively promote a practice of community responsibility by encouraging leaders and organizations to hold themselves accountable for the development they want on the ground, regardless of the position or title they hold. . Because we are the village, and we have to be the change we want to see. “

“PNB is delighted to be a part of the deeper engagement and bigger results offered by Theresa Ruth Howard’s Cultural Competency and Equity Coalition,” said Ellen Walker, Executive Director of the Pacific Northwest Ballet, one of the first to attend. C2EC. “Together with the peers of the coalition, we look forward to embracing and embodying the principles of cultural competence, organizational citizenship and the continued embodiment of the IDEA principles. We know that C2EC’s community of learning, collaboration and accountability will benefit our organization and our field in multiple ways. as the ballet continues its essential and dynamic evolution. “

05 January 2022

An anonymous comment, inspired by the summer festival workshop which excludes men:

This is a difficult article to write: there is clearly an imbalance in the profession, and we must fix it. I’m invariably on the waning end of almost all identity talk and I generally disapprove of most of what is posted here, but I think there’s a need to have this important conversation about how. I think in the future people will write doctorates on gender balance in driving as a microcosm of post-millennial social realignment, but for now I’m deliberately keeping the details as vague as possible …

I have to declare my interest and therefore probably my bias: I’m a young conductor – young enough to be considered a “young artist”, but in the real world I’m not that young. I’ve worked a bit in the US, a lot in Europe, but mostly in the UK, almost all of them with reputable orchestras and opera companies, either as a conductor or an assistant conductor. Maybe I’m not Dudamel, but I’ve always been busy and especially rehired by the people I work with. Orchestras love me, and I think, objectively, that I am quite good at my job, if not a high level… but I still have ambitions for the future. The last few years have been a real struggle, not only because of covid but also because of the politics that now govern the selection of conductors, especially in the UK and US – unless you don’t be a famous old man, and so one way or another. completely immune to all of this. As agents and employers told me over and over again that I was not “viable” for them due to the “political climate” and that it was “difficult to sell young male conductors”, I am struggling to advance in my career. The artistic director of one of the biggest orchestras in the world even told me that I would do a lot better if I was a woman… and they were only half kidding. This question is an open secret. I probably did the best performance of my life with an orchestra with which I had such chemistry, but whose conduct has completely ignored me since; almost all of their communications now focus on diversity and inclusion, and they now have a role exclusively reserved for female conductors. I could list dozens of personal anecdotes about this, but personally I am now starting to have a hard time filling my calendar and wondering if there are any other jobs I can live on.

The flip side is that many female colleagues have been told ‘this is a great time to be a woman’ by managers and agents – I know many of them find this quite difficult to hear because I have had countless conversations about it. To the women who categorically deserve the opportunities they get, this is truly insulting.

However, it became quite difficult to watch these less able and less experienced female colleagues jumping on me and much more talented male chefs than me, making great debuts after great debuts. For generations, I’m sure there have been a lot of women who have felt the same about their male counterparts, and I think for the more conservative upper echelons of our profession that male advantage largely remains. For young conductors, however, I’m pretty sure that being a woman is the most valuable trait you can have to start building professional momentum. Some of these young women will turn out to be exceptional musicians, but my feeling is that disproportionately many could not yet be called competent (I know this finding will upset some). A few years later, I saw the careers of many of them start to slow down after being placed in situations for which they are not yet ready. Few of us mere mortals can progress with the speed of a Simon Rattle or a Klaus Mäkelä, and neither should we, regardless of the pressures of the industry. Sadder still, it reinforces bad stereotypes about female conductors: Female orchestral musicians learn that young female conductors often do not have the level of skill it takes now for a conductor. male obtains an equivalent commitment. As a result, to put it bluntly, they are really giving them a hard time. This is based on anecdotal evidence, and I would love to hear from orchestral players if they have different experiences.

I know that some part of the people who read this will find me rather bitter and probably not a very good conductor. Can’t judge, but I think what I described above is not the way to fix classical music. So actually I’m really happy to see Dartington doing this. Courses like this are where affirmative action should occur, not in the profession. We understand this easily with other elite jobs: if you want great elite athletes or scientists from less represented groups you have to go to young people and train them (A LOT of them), don’t wait the educational outing to then push them to seniors. posts. To do this in the arts is to diminish the importance of what we do. Classes like this are a great way for young musicians to start. And finally, reserving some of these opportunities for young women, especially at the pre-conservatory level, might actually begin to solve the problem of representation in the profession – the pool of conservatory applicants will expand, and then, in turn, the pool of competent conductors available to orchestras. It’s a shame for young men who might miss out, but there are plenty of other opportunities out there at this point in their career as a conductor. It’s definitely a lot better than training, getting experience, making huge sacrifices to become good at what you do, only to then be brought down to the final stage entirely based on your gender. . As with any other job, if you have an experienced and knowledgeable team (as most orchestras are) you need an experienced and knowledgeable manager because otherwise the team cannot do their job. Once you’re in the real world, the genre shouldn’t go there. If we educate people correctly, gender equality will only be a by-product.

Hyderabad: Playing in his first World Blitz event, Telangana chess player Arjun Erigaisi finished in a credible 24th place in a peloton comprising the best players from around the world. The Warangal boy, who recently became India’s No.1 in blitz overtaking Viswanathan Anand, scored 12.5 points in 21 rounds. Considering the stiff competition, Arjun’s performance was impressive.

Arjun, 19, has played impressive draws with Magnus Carlsen, Levon Aronian, Daniil Dubov and Ian Nepomniachtchi. He was also in a good position with 11.5 points after 16 innings and was only 1.5 points behind leader Aronian. However, he slipped from there and suffered three losses – to Vachier-Lagrave, Firouzja and Kravtsiv – which hurt his chances.

Arjun, although a little disappointed that he was not playing his best, said it was a great learning experience. “Playing against strong players in the event was a great experience. I could have done better. I’m disappointed with the overall result, but it was a good experience, ”he said.

He also revealed that his decision to take a draw offered by the World Championship contender Nepomniachtchi in the 17th round was a momentum breaker for him. “Until the 16th round, I was fine. In the 17th round, Nepomniachtchi gave me a draw. I was mesmerized by that because he was such a big player and he gave me a draw. And I took it. But later I realized I was in an advantageous position against him. It was a great learning lesson for me. I then lost the next three laps and fumbled at the end. I also learned that I should not let previous performances affect me in the next matches, ”he explained.
Was he under pressure to participate in such a big tournament for the first time? “No, I wanted to do my best and see how it goes. I didn’t think I was India’s No.1 and should be doing well. I wasn’t nervous either. I did pretty well for the best of the tournament, ”he said.

Arjun, who will be seen in action at the main event of the Tata Steel Chess tournament in the Netherlands from January 14, is aiming for 2,700 ranking points in the classic format. His current ranking points are 2,633.

“I want to do well in this tournament and I want to improve my ranking points. The goal is to reach 2,700 rating points by the first half of the year. I’m working on my openings, ”said Arjun, who is India’s No.8 and No.120 in the world in the classic format.

PUBLISHED ON January 02, 2022


I would like to start with the touching words of Frederick William Robertson: “It is not the number of books you read, nor the variety of sermons you hear, nor the amount of religious conversations that you mix into, but it is ‘is the frequency and the seriousness with which you meditate on these things until the truth in them becomes yours and becomes part of your being, which ensures your growth ”. The nature and function of edification is not limited only to the acquisition of knowledge, the management of knowledge and the application of knowledge under the influence of the mind and the brain; it is, or must be, rather an endless course of spiritual transformation and refinement of human beings.

During the twilight phase of the twentieth century and at the dawn of the new millennium, the world has undergone an unprecedented process of revolutionary changes and transformations concerning all areas of life, in general, and in the field of technology. and education, in particular. Nonetheless, the whole of global society, and in particular the Third World, suffers from an ever increasing number of young people and adolescents facing various types of socio-psychological, emotional and behavioral problems such as depression, aggression, insurgency and, above all, frustration. A manifest decline in adherence to moral values, social norms, human principles and ethical relationships among the flourishing generations speaks volumes about the reasons for the increasing crime rate in society. The most suicidal cases are reported in regions with the highest socio-economic development, the highest literacy rate, the most educated and skilled workforce and, most importantly, the levels of education. most advanced technology and industrialization.

The last century, the most modern and the most progressive, is marred by the anomalous and unleashed developments of globalization, mechanization and industrialization: the deadly world wars for the unjust taking of economic resources and the training of the humanity in the quagmire of materialism, and the fierce competition for survival added dirt to it: the final nail in the coffin of humanism was the bloody battles between the two mutually divergent evils —- capitalism and socialism. The successive decades were to be the phase of melancholy, nihilism, agnosticism and distress and have pushed contemporary generations to the question of individual survival at the cost of socio-humanist degradation. The fear of the reappearance of adversity and calamities consumed the soul from within and slaughtered faith in redemption, belief in peace and humility, and interest in mystical and meditative learning.

So the thirst for truth, knowledge and wisdom was washed away by the bloody thirst for impassive but bodily survival, and spiritualism was devoured by existentialism. As a result, with the reactionary and over-enthusiastic reconstruction and redevelopment campaign, science, technology, management, business and commerce education has taken the wheel and classical and medieval teachings have been thrown into oblivion. The sharp decline in the tendency to opt for the arts, literature, humanities and social sciences for higher education is more than obvious to perceive the gravity of the situation. The classic prestige of pure and intrinsic fine art was eclipsed by the brilliance of graphic arts aimed at commercial enterprise and glamor.

Rightly so, under the heavy burden of an excessive thirst for modernization, greed and mechanization, we have sacrificed the essential spirit and the fundamental purpose of education on the altar of an academic and formal education which rests mainly on the concept of pragmatism and the notion of acquiring professional knowledge and a keen sense of the profession which can lead to business achievement and triumph. Human beings, crown of creatures and conquerors of the universe, were never meant to live a mundane life in one dimension —– the physical dimension —- like other living creatures. There is a “general consensus that humans are spiritual beings who seek to make sense of life and their experiences.” Formerly speaking, the concept of teaching and learning tended rather towards the holistic transformation of learners in a positive and refined way by allowing them to seek and grasp logic, truth and spiritual refinement, at the initial stage. The development of vocational and vocational skills was part of the secondary phase of training and was more of a on-the-job activity than an academic issue. Over time, things apparently continued to revolutionize, but in reality they worsened and deteriorated, and international society has now landed on a planet of socio-cultural chaos. It reminds me of Henry Kravis’ very precious words: “If you don’t have integrity, you have nothing. You can’t buy it. You can have all the money in the world, but if you’re not a moral and ethical person, you really don’t have anything.

Unfortunately, in the contemporary paradigm of corporate culture and the world order of multinational corporations and economics, the interpretation of education and societal growth has been sinfully linked to art and the ability to achieve maximum financial and monetary achievements. Terms like “Career Development”, “Practical Wisdom”, “Motivational Training”, “Learning the Art of Success”, “Mastering Business Management”, “Acquiring Marketing Strategies” and many more are exploited to promote Machiavellianism which teaches the sheer abuse of humanity and ethics in order to forge a path to wealth, fame, status, rank and power, and qualifies this approach as pragmatism and wisdom. Here I have to clarify one thing that I have never been against vocational and vocational education and I have firm faith in the concept that the growing economic problems of modern societies can only be overcome by making sure that the maximum of the population be qualified and trained to earn a living in dignity. and honesty and, thus, contribute to the socio-national economic pool and to progress.

Philosophical interpretations of education and rational debates about the nature and learning process of a young child date back to 500-1000 BC with ancient Greece as the center. The most important and historically authenticated versions of these theories are those which were proposed by later scholars, Socrates, Plato and Aristotle and their academic views on education, with all mutual agreements and disagreements, were anchored in their broader metaphysics, epistemology, ethics. , and political theories. In the comparatively medieval and modern ages, we can turn to big names like Imam Ghazali, Rousseau, John Dewey, and others for further advice. It is remarkably deplorable and overwhelming to perceive that contemporary problems and their resolutions, to a large extent, have already been deliberately meticulously and expansively by these seasoned researchers and scholars long ago. However, the modern world, although it has been tirelessly busy exploring new perspectives to facilitate the learning and training of students in accordance with the socio-ethical and compassion-centered world order, has failed to put implementing such perpetually beneficial philosophies in this regard.

Given our unique religious ideology, socio-moral doctrines, and code of ethics, we can safely use Imam Ghazali’s model of first helping a student to know the reasoning behind creation and the relationship between creation and creator, then enables him to differentiate between evil and virtue, and ultimately teaches him to be a professionally and personally effective unit of society, without exceeding his limits with regard to socio-moral values ​​and religious commandments. The ability to be successful, wise and prosperous in worldly existence is a possible by-product of religious training and spiritual growth and this very individualistic blessing will surely be reflected throughout society. Ghazali emphasizes “inner science with outer science” and advises teachers to express and share their intuitive and spiritual experiences and ideas with their students without any hesitation or delay, as this is an integral part of their teaching. tutoring responsibility. Here I have to quote Western theorist Andrew Linzey who is of the opinion: “Moral education, as I understand it, is not about instilling obedience to the law or cultivating self-virtue, it is. rather, it is about finding in us an ever increasing sense of the value of creation. It’s about how we can develop and deepen our intuitive sense of beauty and creativity ”.

Like Imam Ghazali, so many gigantic scholars and intellectuals, from various religious backgrounds, in Western countries and other parts of the world, have emphasized the religious and spiritual aspects of education, citing references to holy books. Among more recent researchers, Dirkx believes that “brain-based” theories and the concept of “emotional intelligence” suggest that emotions and feelings are deeply linked to the perception and processing of information from our external environments, the storage and retrieval of information in memory, reasoning, and the embodiment of learning. Only a psychologically and emotionally balanced person, with the quest for enlightenment and growth, a vision for the future and a mission for the world around them, can prove to be a capable learner and, most importantly, a good contributor to society in return.

To conclude, to be more precise, we can take the example of aptitude tests which are carried out before finalizing students for admission into diversified academic disciplines or choosing the right candidates for certain professional and professional responsibilities. Then we organize their professional training workshops to finish them according to the specific requirement or model because we believe that not every field of work and every grade or position is suitable for everyone. In a broader spectrum, this is the absolute and essential prerequisite for preparing a child to be an honest, conscientious and trustworthy citizen of society before imparting technical training and higher education for goals and commitments. specific because without reaching a certain pedestal, platform or foundation, it will certainly fall if exposed to the following steps. The world has witnessed this genius, shrewd, nerdy and artisan comrades, devoid of moral education and ethical refinement, wreak havoc with mankind and civilizations when the evil genius goes. Blunders and depravities are always committed by the expertise sitting in the upper chambers of authority and domination: the laity have access only to human errors and small-scale deviations.

The spirit was severely bruised in tumultuous 2021 with the second wave leaving us in a state of struggle. After a disastrous year, in which live concerts were completely absent, the music slowly and steadily returned to the forefront. And of course there were those who found music in dark times too, in studios, in their rooms and made us smile. From a heartwarming concert in Chashm-e-Shahi in Kashmir, young artists donning the mantle for the year to deliver music that made us hear despite a numb state of mind at the Grammys learning about racial diversity and acquisitions billion dollar musical events, the year has been a busy one. Here are the artists and stories from the music world of 2021.

Valley Notes

It is not often that a classical music concert arrives in Kashmir. With the Zabarwan mountains as a backdrop, Chashm-e-Shahi, the Mughal paradise garden came alive with raag Yaman, a raga whose creation is attributed to Amir Khusrau. Eighty-year-old flute master Pt Hariprasad Chaurasia took the fundamental raga and played with it for about 40 minutes, his Parkison causing him to work harder than usual. The air was sometimes lost, but not the spirit. He was ably supported by tabla player Pt Ram Kumar Mishra and his students Devapriya, Amrita Uprety and Vaishnavi Joshi. Organized by SPIC MACAY as part of Azaadi ka Amrit Mahotsav, the concert titled Wadi-e-Kashmir was an extension of the organization’s famous “Music in the Park” series.

Independent Artist of the Year: Vasundhara Vee

A few names caught our attention including Pavithra Chari, half of Delhi-based duo Shadow and Light, Mumbai-based singer-songwriter Saachi Rajadhyaksha and Bangluru-based L’Nee Golay, which was a sweet reminder of a Winehouse-esque Amy Ambiance, the band was led by Vasundhara Vee, who made our heads spin with his powerful and lush vocals in the absolutely uplifting single, his first solo, Run – the piece that includes ‘notes to self’ . The only name in India at this point that commands respect as the best jazz singer who can deliver soul like no one else, this time Vasundhara sounds different. There is a departure from his associated acts such as Adil and Vasundhara and more recently Merkaba. Now she is a solo artist who reveals her heart to us. The whiskey-tinged voice and honest lyrics are hard to miss. Produced by Dhruv Ghanekar, the song and video took the game several miles into 202q. Other artists will have to work very hard to get to where Vasundhara is at this point – self-aware, in love with herself, complex, hungry, and with new ideas and music in tow. Watch out for this one. She will be a pioneer in 2022.

Vasundhara Vee turned heads with Run.

Classically yours

Abhishek Raghuram: Among the young singers – Hindustani and Carnatic – Abhishek Raghuram, 36, is one of the best singers at this stage. He was in great shape in the December musical season in Chennai, most notably with performances by raag Bihag and Hamsanandi, which showcased his extraordinary vision of music and musicality. Sometimes during his performance a taan, a particular phrase, may seem incomprehensible to even some of the most experienced musicians, but the tenderness with which Raghuram tempts them is worth attending every concert of him. A pupil of the guru PS Narayanaswamy, he is the grandson of the iconic mridangam player Palghat Raghu and related to the famous Lalgudi family on his mother’s side. He is also related to the singer Ghazal Hariharan. A unique performer, he has had a special year and is likely to bring us more wonderful music in the coming year.

Pratibha Singh Baghel: Reality show contestant Pratibha Singh Baghel garnered a lot of attention as Umrao Jaan in the musical Umrao Jaan Ada which was staged in the capital in 2019 – 38 years after the screening of Umrao Jaan of Muzaffar Ali. Her Instagram posts have garnered a lot of attention, as have the online shows she did on her YouTube channel during the lockdown. But what catapulted her to fame was Bole Naina (Sufiscore), a ghazal album written by Gulzar and composed by Deepak Pandit, the violinist who performed with Jagjit Singh for years. The album also had Ut Zakir Hussain leading the percussion team. What’s interesting about Baghel’s voice is how his voice has a unique transformative quality and easily moves through ghazal, qalam sufiana, and contemporary film song, among others. Then there is a strong capacity for improvisation. Baghel is an artist to watch in 2022, with a plethora of songs and projects in the works.

Ishaan Leonard Rao: One classical artist who has gained attention this year is pianist Ishaan Leonard Rao, 17, who until a few years ago could be seen in the audience while his parents – sitar player Shubhendra Rao and the cellist Saskia Rao performed together. But the Rao family got together for a concert this year where Ishaan dove deep into the world of Mozart and worked on Indian classical scales to showcase his stormy reworkings of some of the pieces. The fact that three artists understood the rulebook of the two forms was what added to the cohesion of the concert. Ishaan also started “The Piano Project” in which he created lesson videos, a lesson book and a website for those who do not have access to piano instruction otherwise. He started his lessons with children from the Parivartan of the Takshila Education Society, Bihar. He also continued to perform at the National Gallery of Modern Art this year.

Sinhala wonder

Yohani D’silva has gone viral this year.

After embalming the hearts of quarantined Sri Lankans, 28 “Manika maake” by Yohani D’Silva It reached India, garnering over 110 million views in no time. The Sinhala song broke the internet, with celebrities to common people getting excited over its simple melody on repeat. From Hindi film actors Madhuri Dixit, Parineeti Chopra and Tiger Shroff, everyone sang and danced on the room and posted videos on their social media. The popularity spawned covers from all over the world, both instrumental and in many languages ​​- Tamil, English, Telugu, Konkani, Hindi, Bengali, and Kokborok of Tripura, among others. This has boosted a number of TikTok videos, Instagram posts, and memes. YouTube pushed Silva to instant fame. In Colombo, the YouTube star was sitting at her home watching what it was like to go viral. It was the world moment of the unintentional single. “It was a really random rendition of the song. It wasn’t planned. We never thought it would appeal to so many people,” de Silva told The Indian Express in a video interview.

Smooth like butter

In May of this year, the seven-member boy band BTS became the first K-pop group topped the Billboard 200. They also put their fans – the ARMY as they are called – especially a plethora of teenage girls around the world in hysterical rapture. Their song Butter went viral and the fluid synths of the pop dance number and those fabulous dance moves brought back memories of the pop world past. The song sounds good to begin with – a fun number that hit us while on lockdown. But then it sticks, grows in your heart until you hum.

Lesson for the Grammys

The year began with the Recording Academy coming under fire for lack of diversity in its nominations. Three of the five nominees for the Best Children’s Album category refused to accept the nomination because of “all white” musicians, including themselves. Fit since America questioned and continues to question racial fairness. Musician Alistair Moock and comedians Dog on Fleas and the Okee Dokee Brothers didn’t want to be nominated for the Grammys. Conversations ensued that led to policy changes by the Academy, resulting in a very different type of nominating list in 2021 – five artists of color were nominated. Under the new policy, applicants in non-craft categories such as children’s music will be chosen by their peers. A marked change from the lack of transparency that existed in the system. The ceremony is slated to take place in January 2022. What makes the category interesting is the nomination of Indian-American singer Falguni Shah, who placed in the top five for her album A Colorful World.

Money matters

The music acquisition arena was a hotbed of activity in 2021. After nearly decades of instability over piracy and free access issues that have reduced demand for the purchase of new music, the music industry music has seen billions of dollars poured into it. There were huge deals in which artists sold their music and their copyright. The trend started in 2020 when Universal Group acquired Bob Dylan’s entire music catalog for almost $ 400 million. The catalog, comprising over 600 songs from six decades, covered iconic tracks like “Blowin in the Wind” and “Like a Rolling Stone”. Months after Dylan, the music of singer-songwriter David Crosby was finally acquired in March 2021 by US entertainment executives Olivier Chastan and Irving Azoff’s Iconic Artist Group just after the company bought a controlling stake. in Beach Boys Intellectual Property, including recording, editing and branding. Colombian pop star Shakira followed, selling his catalog of 145 songs, including his Olympic anthem “Waka Waka”, and popular tracks like “Hips Don’t Lie” and “Whenever, where” to Hipgnosis Songs Fund, a publicly traded investment company based UK which has also acquired music catalogs from Canadian singer-songwriter Neil Young, former Fleetwood singer Mac Lindsey Buckingham, English musician Steve Winwood and award-winning producer Andrew Watt. Grammy Award, among others. The company is valued at $ 2.21 billion.

The streaming platforms and their increased revenue possibilities are one of the main reasons here. Streaming services like Spotify and iTunes, among others, have created an atmosphere that encourages many businesses, large and small, to want to invest in music. They understand that GenZ and millennials spend big on streaming platforms. The trend is also expected to continue this year.

Bollywood Newspapers

Shershaah’s songs – Rataan lambiyaan and Raanjha top the charts on most streaming platforms. But for us, it was B Praak’s old composition “Metho tera man bhareya” that stood out as a musical beauty in the same film. A notable mention here is Arijit Singh Pagglait’s debut album. A one hour 34 minute album is a thing of the past but Pagglait gave us old world nostalgia. It was a very cleverly designed album with folk melting into the contemporary with a lot of finesse. The best was the background score, which was absolutely lovely. Another song that stood out this year was “Bandar baant” in Sherni by Amit Masurkar. From the secular story – Two cats and the monkey – Hussain Haidri’s satire is composed by Bandish Projekt. As fabulous as the poetry is, we would like it to be sung a little clearly. Some words get lost because it’s sung too fast.

From a Burger King to a concert hall, with the help of Frank Gehry Tue, 28 Dec 2021 00:56:34 +0000 INGLEWOOD, Calif .– Noemi Guzman, a 17-year-old high school student, usually has to find a place to practice the violin – the instrument she calls “literally, the love of my life.” But the other Saturday morning, Guzman joined a string ensemble performing on a stage here that’s almost as grand and acoustically tuned as the […]]]>

INGLEWOOD, Calif .– Noemi Guzman, a 17-year-old high school student, usually has to find a place to practice the violin – the instrument she calls “literally, the love of my life.” But the other Saturday morning, Guzman joined a string ensemble performing on a stage here that’s almost as grand and acoustically tuned as the place she dreams of someday performing: Walt Disney Concert Hall, the home of the Los Angeles Philharmonic Orchestra.

“It’s beautiful,” Guzman said during a break after a training session at YOLA’s Judith and Thomas L. Beckmen Center, his voice muffled by a mask. “To have a space that you can call your own. This is our space. It is created for us.

Inglewood, a working-class town three miles from the Los Angeles Airport that was once rife with crime and poverty, is in the midst of a high-profile, largely sports-focused economic transformation: the SoFi Stadium of 70 Seating, which opened here last year, now the home of the Rams and Chargers, will be the site of the Super Bowl in February and will be used during the 2028 Summer Olympics. Construction is In progress on an 18,000 seat arena for the Los Angeles Clippers basketball team.

But the transformation of Inglewood, historically one of the largest black communities in this region, is also exemplified by the 25,000 square foot building where Guzman was training the other morning. The building, which opened in October, is the first permanent headquarters of the Youth Orchestra Los Angeles and is the product of a collaboration between two of Los Angeles’ most prominent cultural figures: Gustavo Dudamel, artistic director of Los Angeles. Philharmonic, which oversees YOLA, and Frank Gehry, the architect who designed the Walt Disney Concert Hall.

“It was an old bank,” said Dudamel, who has long been friends with Gehry, a classical music lover who can often be spotted in the seats of the hall he designed. “Then it was a Burger King – yes, a Burger King! Frank saw the potential. What we have there is a scene the same dimensions as Disney Hall. “

The $ 23.5 million project is a highlight for YOLA, the music education program for young people that was founded here 15 years ago under Dudamel and which he calls the iconic achievement of his tenure. It accommodates 1,500 students, aged 5 to 18, who come to study, practice and play music on instruments provided by the Los Angeles Philharmonic. It was modeled after El Sistema, the music education program for young people in Venezuela where Dudamel studied the violin as a child.

And this is one of the most striking examples of the efforts of the country’s leading arts organizations to bring youth education programs to communities, rather than concentrating them in city centers or urban artistic neighborhoods. . “You can’t just do it downtown,” said Karen Mack, executive director of LA Commons, a community arts organization. “If you really want it to have the possible impact with this program, you have to make it known to the community. It must be accessible. “

Gehry called this idea the “whole game”.

“It’s not the community that has to come to Disney Hall,” he said, “but the Disney Hall that comes into the community.”

For Inglewood, the new YOLA center is a notable addition to what has been a transformative wave of stadium and arena construction, which has spurred a wave of commercial and residential development (and with that, concerns about gentrification that follows. often this type of development). Until 2016, Inglewood was primarily known as the home of the Forum, the 45-year-old arena where the Lakers and Kings once played before moving to what was known as Staples Center in downtown Los Angeles, and Hollywood Park Racetrack, which closed to make way for the SoFi Stadium.

“We have never been known for cultural enrichment,” said James T. Butts Jr., the mayor of Inglewood. “That’s why it’s so important to us. What is happening now is a district of society and culture: we will no longer be known only for sports and entertainment.

Even before the opening of the Beckmen Center, YOLA could be an exhilarating experience for a school-aged student considering a career in music. Guzman, who joined the youth orchestra seven years ago, has performed bow to bow with members of the Los Angeles Philharmonic, under the direction of Dudamel. YOLA musicians have joined the Disney Hall Philharmonic Orchestra, the Hollywood Bowl, and toured places such as Tokyo, Seoul and Mexico City.

Christine Kiva, 15, who started playing cello at age 7, now studies with cellists at the Philharmonie. “It helped me develop my sound as a cellist and work on a cello repertoire,” she said.

Inglewood is the fifth economically stressed neighborhood where the youth organization has established an outpost. But in the first four locations, it shares space with other organizations, forced to fit in without a full-fledged performance space or practice rooms. “We were running the project in spaces that weren’t specifically designed for music,” said Chad Smith, general manager of the Los Angeles Philharmonic.

Now, the words “Judith and Thomas L. Beckmen YOLA Center,” named after the philanthropists and vineyard owners who have donated the largest amount to the project, sprawl across the front of the renovated building overlooking South La Brea Avenue and the old city center. Dudamel has an office there. Members of the Los Angeles Philharmonic show up regularly to observe the practice and work with the students.

This building has a lot of rooms for students to practice. There are 272 seats on benches in the main hall, which can be tucked into a wall, allowing the hall to be divided in half so that two orchestras can practice at the same time. The acoustics were designed by Nagata Acoustics, who also designed the acoustics of the Disney Hall.

The building was owned by Inglewood, who sold it to the Los Angeles Philharmonic. “When we first walked in, it still had the greasy smell of a Burger King,” said Elsje Kibler-Vermaas, vice president of learning for the Los Angeles Philharmonic. Gehry, who had previously worked with Dudamel on projects including designs for opera “Don Giovanni” in 2012 – agreed to take a look at the building, a former bank that opened in 1965.

He said when they brought him there he was struck by the low ceilings of his time as a bank.

“I said: ‘is it possible to do an intervention?’ Remembers Gehry who, even at 92, is involved in a series of design projects across Los Angeles.

By drilling a hole in his ceiling and installing a skylight, and drilling a hole in the floor to deepen the room, he was able to create a performance space with a 45-foot-high ceiling, close to that of Disney Hall. “The children will have a real experience playing in this kind of room,” he said.

It turned out to be a $ 2 million conversation; the total price, including the purchase of the building and its renovation, increased from $ 21 million to $ 23.5 million to cover the additional costs of raising the roof, installing a skylight and d lowering the floor.

The building was busy the other day. The students had come for afternoon music lessons in elementary schools, most of them in Inglewood, and after snacks – bananas, apples, granola bars – they rushed to their music reading, percussion lessons. and monitoring of a conductor.

“Pay attention!” said Mario Raven, leading his students in a singing and music reading class. “Here we go, one, two, three! “

The brass were outside because of the Covid-19 concerns (it’s difficult to play the French horn while wearing a mask). As the planes flew over, they executed “High hopes”By Panic! at Disco, suggesting that a youth orchestra does not need to live only with Brahms and Beethoven.

Students typically take 12-18 hours of instruction per week for 44 weeks per year. About a quarter of them end up specializing in music. Smith said this was reflected in the program’s broader aspirations. “Our goal was not that we were going to train the greatest musicians in the world,” he said. “Our goal was to provide music education to develop students’ self-esteem through music. “

Dudamel said his experience as a boy in Venezuela was instrumental in bringing the program to Los Angeles. “I grew up in an orchestra where they called us, in the press, the orchestra without a ceiling,” he said in an interview with Zoom from France, where he is now also musical director of the Opera. from Paris. “Because we didn’t have a place to rehearse. We have made a dream come true where young people have the best things they can have. A good room. Great teachers.

“Look, this is no ordinary music school,” he added. “We don’t pretend to be a conservatory. Maybe they won’t be musicians in the future. But our goal is for them to have music in their life, because it brings beauty, it brings discipline through art.

Convolutional neural networks have the limitation that they learn inefficiently if the dimension of the data or the model is very large. Thus, Seunghyeok Oh et al. showed how to use quantum computing and CNN to develop a more efficient and performant technique that can be applied to solve complex machine learning tasks. This technique that integrates both CNN and quantum computing is called a quantum convolutional neural network (QCNN). In this article, we will have a deep understanding of QCNN with its paradigm and applications. Here are the key points that will be covered in this article.


  1. CNN standard
  2. What is quantum computing?
  3. The QuantumCNN Paradigm (QCNN)
  4. QCNN applications

Let’s start the discussion by reviewing how CNN approaches tasks.

CNN standard

Among many classification models, the Convolutional Neural Network (CNN) has demonstrated exceptional performance in computer vision. Photographs and other images that reflect the real world have a strong correlation between surrounding pixels.

The fully connected layer, which is a fundamental model of deep learning, has performed well in machine learning, but there is no way to maintain the correlation. CNN, on the other hand, can directly store correlation information, allowing more accurate performance evaluation.

CNN works primarily by stacking the layers of convolution and pooling together. The convolutional layer uses linear combinations between surrounding pixels to find new hidden data. The pooling layer reduces the feature map, reducing the required learning resources and preventing overfitting.

The result of the classification is achieved by using the fully connected layer after the data size has been sufficiently reduced by repeatedly applying these layers. For best results, the loss between the acquired label and the actual label can be used to train the model using a gradient descent method or other optimizers.

Numerous studies have been published that combine the quantum computing system and the CNN model are able to solve real world problems that are difficult with machine learning using the quantum convolutional neural network (QCNN).

There is a method for effectively solving quantum physics problems by applying the CNN structure to a quantum system, as well as a method for improving performance by adding a quantum system to the problems previously solved by CNN.

Before moving on to QCNN, we must first understand what quantum computing and computing is.

What is quantum computing?

Quantum computing is gaining ground as a new way to solve problems that traditional computing techniques cannot solve. Quantum computers have a different computing environment than traditional computers.

Quantum computers, in particular, can use superposition and entanglement, which are not seen in traditional computing environments, to achieve high performance through qubit parallelism. Here the qubit is referred to as a quantum bit, which is basically a unit of quantum information.

Quantum computing is seen as a new solution to algorithmic problems that are difficult to solve because of these advantages. Various studies using quantum computing models are also being carried out in the field of machine learning. Moreover, since the optimization of quantum devices using the gradient descent method has been studied, it is possible to quickly learn quantum machine learning using hyperparameters.

The QuantumCNN paradigm

QCNN, or Quantum Convolutional Neural Network, extends key features and structures of existing CNN to quantum systems. When a quantum physics problem defined in N-body Hilbert space is transferred to a classical computing environment, the size of the data increases exponentially in proportion to the size of the system, making it unsuitable for efficient solutions. Since data in a quantum environment can be expressed using qubits, the problem can be avoided by applying a CNN structure to a quantum computer.

Let us now see the architecture of the QCNN model.

As the above architecture shows, the QCNN model applies the convolutional layer and the pooling layer which are the key characteristics of CNN, to quantum systems.

  1. The hidden state is discovered by applying multiple qubit gates between adjacent qubits in the convolution circuit.
  2. The pooling circuit reduces the size of the quantum system by observing the fraction of qubit or by applying CNOT gates to only two qubit gates.
  3. Recreate the convolution and grouping circuits from steps 1 and 2.
  4. If the size of the system is small enough, the classification result is predicted by a fully connected circuit.

Multiscale Entanglement Renormalization Ansatz (MERA) is commonly used to satisfy this structure. MERA is a model for efficiently simulating multibody quantum systems. MERA now adds qubits to the quantum system, increasing its size exponentially for each depth.

This MERA is used in reverse by QCNN. The inverted MERA, which is suitable as a model of QCNN, reduces the size of the quantum system exponentially from the data provided.

QCNN applications

One of CNN’s most popular applications is in the area of ​​image classification. In terms of superposition and parallel computing, quantum computers offer significant advantages. Quantum Convolutional Neural Network improves CNN performance by incorporating quantum environments. In this section, we will see how the QCNN can help with the classification of images.

The quantum convolution layer is a layer in a quantum system that behaves like a convolution layer. To obtain feature maps composed of new data, the quantum convolution layer applies a filter to the input feature map. Unlike the convolutional layer, the quantum convolutional layer uses a quantum computing environment for filtering.

Quantum computers offer superposition and parallel computing, which are not available in classical computing and can reduce learning and evaluation time. Existing quantum computers, on the other hand, are still limited to small quantum systems.

Small quantum computers can build the quantum convolution layer because it does not apply the entire image map to a quantum system at once, but rather processes it as much as the filter size at a time.

The quantum convolution layer can be constructed as shown in the diagram below. Here is an explanation of how the concept works:

  1. During the encoding process, the pixel data corresponding to the filter size is stored in qubits.
  2. Filters of learnable quantum circuits can detect the hidden state from the input state.
  3. The decoding process obtains new classical data by measurement.
  4. To complete the new trait map, repeat steps 1 through 3 one more time.

The encoding of the first step is a process that converts classical information into quantum information. The simplest method is to apply a rotation gate to the qubits that match the pixel data. Of course, different encoding methods exist, and the encoding method chosen can affect the number of qubits required as well as the efficiency of learning. The third decoding process is based on the measurement of one or more quantum states. Classical data is determined by measuring quantum states.

A combination of several gates can be used to create the random quantum circuit in the second step. By adding variable gates, the circuit can also perform optimization using the gradient descent method. This circuit can be designed in a variety of ways, each of which has an impact on learning performance.

Final words

Through this article, we have seen how QCNN uses a CNN model and quantum computing environment to enable a variety of approaches in the field. Fully parameterized quantum convolutional neural networks open promising results for quantum machine learning and data science applications. Outside of this discussion, if you want to look into a practical implementation of the QCNN, I recommend that you look at the TensorFlow implementation and the research team as mentioned in the introduction.
