ABSTRACT
Rigorous Coupled Wave Analysis (RCWA) method is highly efficient for the simulation of diffraction efficiency and field distribution patterns in periodic structures and textured optoelectronic devices. GPU has been increasingly used in complex scientific problems such as climate simulation and the latest Covid-19 spread model. In this paper, we break down the RCWA simulation problem to key computational steps (eigensystem solution, matrix inversion/multiplication) and investigate speed performance provided by optimized linear algebra GPU libraries in comparison to multithreaded Intel MKL CPU library running on IRIDIS 5 supercomputer (1 NVIDIA v100 GPU and 40 Intel Xeon Gold 6138 cores CPU). Our work shows that GPU outperforms CPU significantly for all required steps. Eigensystem solution becomes 60% faster, Matrix inversion improves with size achieving 8x faster for large matrixes. Most significantly, matrix multiplication becomes 40x faster for small and 5x faster for large matrix sizes. © 2023 SPIE.
ABSTRACT
Goal. The goal of the paper is to show the implementation of library services in the homes for older adults in the city of Zagreb during the COVID-19 pandemic from March 2020 to June 2022. Approach/methodology/design. Library services in homes for the older adults in the city of Zagreb are implemented within the Books at your door programme of the 65 plus project at the Zagreb City Libraries. The COVID-19 pandemic and related restrictions have made it difficult to design and implement library services for older people in libraries. Due to the protection of health, particularly large restrictions have been placed on contacts with elderly people in homes for the older adults. As a result of this challenge, the librarians have devised ways to stay in touch and provide library services to the home users during periods of greater and lesser restrictions on access to the homes. Results. The paper describes in detail the implementation and the results of the Books at your door programme from March 2020 to June 2022. Library services and various cultural programs that were carried out during the pandemic in homes for the older adults, organized by the Zagreb City Libraries, are presented and described. The results are based on and supported by the statistical data from the annual reports of the 65 plus project. Originality/value. The cultural activities that are carried out for the older adults by the libraries, sometimes in difficult business circumstances, are examples of good practice aimed at sensitizing the public and increasing care for the well-being of the elderly people. The experiences gained during the implementation of the Books at your door programme in difficult conditions during the pandemic can help experts and practitioners in designing library services in times of crisis. The data recorded in this paper also represent a kind of public archive on the cooperation between libraries and homes for the older adults in the Zagreb area during the COVID-19 pandemic. © 2023, Hrvatsko Knjiznicarsko Drustvo.

ABSTRACT
The pandemic forced many education providers to pivot rapidly their models of education to increased online provision, raising concerns that this may accentuate effects of digital poverty on education. Digital footprints created by learning analytics systems contain a wealth of information about student engagement. Combining these data with student demographics can provide significant insights into the behaviours of different groups. Here we present a comparison of students' data from disadvantaged versus non-disadvantaged backgrounds on four different engagement measures. Our results showed some indications of effects of disadvantage on student engagement in a UK university, but with differential effects for asynchronously versus synchronously delivered digital material. Pre-pandemic, students from disadvantaged backgrounds attended more live teaching, watched more pre-recorded lectures, and checked out more library books than students from non-disadvantaged backgrounds. Peri-pandemic, where teaching was almost entirely online, these differences either disappeared (attendance and library book checkouts), or even reversed such that disadvantaged students viewed significantly fewer pre-recorded lectures. These findings have important implications for future research on student engagement and for institutions wishing to provide equitable opportunities to their students, both peri- and post-pandemic.
ABSTRACT
This paper presents a study of Indian media. Utilizing the Propaganda Model formulated by Herman and Chomsky in the book Manufacturing Consent: The Political Economy of Mass Media (1988), the paper aims to critically assess the news patterns and media performance of the mainstream Indian media. The contribution of the paper will be the application of the propaganda model in the context of Indian media. For this study, we have analyzed the media coverage of two events – India's ban on Chinese apps and the Pulwama attack. We focus on how Indian Media has helped the Government to establish the propaganda of nationalism during both events, which is explained by Herman and Chomsky in the five filters of news production. We investigate how the anti-China sentiment and the Pulwama attack have been used by the Government to divert attention from their failure of governance, and mismanagement of the COVID-19 pandemic. The corporate media is playing its part in the machinations of the ruling BJP party. We conclude that the plurality of voices amongst journalists is in decline.

ABSTRACT
Introduction: The COVID-19 pandemic and duty hour restrictions have illuminated a role for surgical simulation in trainees that permits meaningful technical experience outside the operating room. There is a need for the implementation of surgical simulation infrastructure adjacent to clinical training with practical considerations for complexity and cost. This systematic review analyzes surgical simulations that train hand surgical techniques and procedures with subjective or objective competency assessment. Method(s): A systematic review was conducted according to PRISMA- P guidelines using the PubMed, Medline, Scopus, Embase, Web of Science, and Cochrane databases. Selected search terms included procedures relevant to the field of hand surgery and various types of simulation training. Data, including skills and techniques taught and assessed, model type, equipment, cost, and emphasis placed in training for each article, were extracted. Result(s): Of 2,519 articles, 40 met inclusion criteria. Models were described as: synthetic benchtop/3D-printed (40.0%), animal (22.5%), cadaveric (20.0%), augmented and virtual reality (AR/ VR;12.5%), and other computer simulation (12.5%). Three models incorporated both a physical benchtop component and an AR/ VR component. The procedures most represented included tendon repair (30.0%), fracture fixation (27.5%), wrist arthroscopy (15.0%), and carpal tunnel release (15.0%). Sixty-five percent of articles emphasized the importance of surgical simulation in a surgeon's training. Conclusion(s): A diversity of surgical simulation models exist for the practice of various aspects of hand surgery. The existing literature demonstrates their utility for increasing expertise with surgical techniques and procedures in a low-risk setting.
ABSTRACT
Objectives: A LSR is a systematic review that is continually updated, incorporating new evidence as it becomes available. They are conducted in research areas where new evidence is constantly emerging on diagnostic methods, treatments, and outcomes. The objective of this study was to understand the current application of LSRs across research areas. Method(s): Embase, MEDLINE, and the Cochrane Database of Systematic Reviews were searched to identify LSRs. Only the most recent update of a LSR was included. Data regarding the indication, intervention, methods, frequency of updates, and funding were extracted. Result(s): Of the 1,243 records identified, 126 LSRs were included for analysis. The first LSR was published in 2015, with a significant increase in the number of LSRs published starting in 2020, coinciding with the COVID-19 pandemic. The most common indication represented by LSRs was COVID-19 (72%), followed by oncology (10%). Other indications with LSRs included chronic pain, traumatic brain injury, and skin disorders, among others. While most oncology LSRs identified interventional randomized-controlled trials (RCTs) (85%), only 54% of COVID-19 LSRs were restricted to interventional studies, including a combination of RCTS and real-world observational studies. Oncology LSRs included common cancers such as prostate, renal, or multiple myeloma. Of the reviews that reported update frequency, 28% planned monthly, 12% yearly, and 12% weekly updates. Only 46% of LSRs were registered. The majority of LSRs were funded by government or research organizations. Objectives of LSRs varied, with most stating the need to maintain up-to-date databases;however, several studies used LSRs to facilitate network meta-analysis or mixed treatment comparisons. Conclusion(s): While LSRs were introduced over five years ago, their frequency increased during the COVID-19 pandemic. Apart from COVID-19, LSRs are commonly used in oncology settings. LSRs provide high-level, relevant, and up-to-date evidence, making them a useful tool for clinical and real-world research.Copyright © 2023
ABSTRACT
Library and Information Science (LIS) education is very different now from how we used to know it. Currently, reassessing student assessment has been at the heart of several experiments to do away with over-emphasis on retention, reproduction, and memorization. This article highlights both sides of the debate—traditional versus e-assessments—and answers critical questions about the controversial topic. The research draws on a viewpoint approach with dependence on the author's opinion and interpretation of the literature review in the pro-con discussion where both sides of a controversial traditional versus digital assessment topic are presented. We should not shy away from confronting uncomfortable truths. Assessment involves humanizing, power negotiation, empowerment, entitlement, persuasion, substitution, and student care. We require a multifaceted effort to seize the moment of COVID-19 to improve assessment by blending traditional and electronic forms. The originality is the enrichment and domestication of LIS education in a more nuanced discussion and evaluation of changes in student assessment brought on by the shift to online education during the pandemic. The conclusion indicates the need to meld traditional and innovative modes of assessment, which should be an ongoing part of any successful educational program modeled on context-specific needs.
ABSTRACT
PurposePrior to 2020, University of California, Los Angeles (UCLA) Library's research services spanned multiple service points. Multiple locations were staffed by Library Student Research Assistants (LSRAs) and each location was supervised independently. While efforts to increase collaboration had been underway, much of the work and services remained siloed and often duplicated training and service hours.Design/methodology/approachWith the onset of coronavirus disease 2019 (COVID-19), UCLA Library rapidly transitioned from entirely in-person to entirely online services. With multiple service points pivoting, UCLA was redundant to have multiple online desks providing Zoom appointments and that quickly became apparent. Moreover, transitioning in-person student work to remote work was paramount to providing both normal services to users and allowing LSRAs to keep jobs during a time of uncertainty and insecurity.FindingsWhile the authors' original consolidation of services and implementation of shared supervision was a result of the pandemic and primarily involved online services, the authors have maintained this shared approach and collaborative vision in returning to in-person services. For the past year, the authors have offered shared in-person (at two library locations) and online services. As subject-specific library locations begin to reopen their desks, the authors continue to identify ways to leverage shared supervision and a robust referral model for those on-site services while negotiating student staffing and the need for both general and subject-specific services.Originality/valueThe authors present a novel approach to peer-to-peer teaching and learning and research services and shared student worker supervision with services coordinated across multiple locations and disciplines within a large academic library serving a large student population.
ABSTRACT
During the pandemic, instruction moved online, and physical formats of media were unable to be used. This presented the opportunity to undertake a quantitative study on the use of streaming videos, particularly in the sciences, at Colorado College. The authors used vendor statistics for the last 5 years (2016–2017 to 2020–2021) and reviewed the time period of March–February, which is what the authors refer to as the covid year. By 2021, streaming videos were being used 25 times more than in 2016, and science videos were being streamed 26 times as much.
ABSTRACT
This study serves as a follow-up on a 2020 study by Wang and Lund that examined the policy changes and announcement information provided by American public libraries during the early weeks of the coronavirus (COVID-19) pandemic, using the same list of libraries as the 2020 study to examine how the COVID response evolved over the past two years. Seven types of information were collected from the public libraries' websites, with the help of the Internet Archive to collect specific dates: frequency of announcement updates, date of start curbside/pickup services, date of reopening libraries, dates of posting vaccine-related information, dates of removal of COVID-19 related information, and dates of reopening face-to-face programs. The findings indicate that the timing of COVID response updates varied based on factors including the size of the municipality in which the public library is located and the political leaning of the municipality's voters.

ABSTRACT
With the extraordinary growth in images and video data sets, there is a mind-boggling want for programmed understanding and evaluation of data with the assistance of smart frameworks, since physically it is a long way off. Individuals, unlike robots, have a limited capacity to distinguish unexpected expressions. As a result, the programmed face proximity frame- work is important in face identification, appearance recognition, head-present evaluation, human-PC cooperation, and other applications. Software that uses facial recognition for face detection and identification is regarded as biometric. This study converts the mathematical aspects of a person's face into a face print, which is then stored in a database to verify an individual's identification. A deep learning system compares a digital image or an image taken quickly to a previously stored image(which is saved in the database). The face has a significant function in interpersonal communication for identifying oneself. Face recognition technology determines the size and placement of a human face in a digital picture. Facial recognition software has a wide range of uses in the consumer market and in the security and surveillance sectors. The COVID pandemic has brought facial recognition into greater focus lately than ever before. Face detection and recognition play a vital part in security systems that people need to interact with without making physical contact. The pattern of online exam proctoring is employing face detection and recognition. Facial recognition is used in the airline sector to enable rapid, accurate identification and verification at every stage of the passenger trip. In this research, we focused on image quality because it is the major drawback in existing algorithms and used OPEN CV, Face Recognition, and designed algorithms using libraries in python. This study discusses a method for facial recognition along with its implementation and applications. © 2023 IEEE.
ABSTRACT
Background: During covid-19 period not only general public was victim of anxiety besides all medical professional also face anxiety and change their Information seeking behaviour according their personality. Curiosity is in human nature with the easy access to internet the new horizon to information has been opened. People searching trends have shown that they are interested in health risk to health treatment for their health related problems. Aim(s): In this study examined the influences of anxiety (ISA) and Personality traits (PT) on health information seeking behaviour (HISB) among the Doctor, paraprofessional and final year medical students who are frontline worker during pandemic situation. Methodology: The study adopted survey method with non-probability convenience sampling to collect statistical. Questionnaires werefiled from 313 participants by utilizing convenient sampling and analyzing the data through SPSS. Result(s): The result showed that significant relation between personality traits, information seeking anxiety and health information seeking behaviour. In medical library user PT has significant impact on HISB (p<.05), (AVG_PT=.002) and ISA has impact on HISB but it is not significant in medical professional (beta -.070) value shows ISA has negative impact on HISB. Practical implication: This study will be beneficial for information professionals, health care workers, policy makers and administrators to access of information resources in hybrid format. Conclusion(s): Medical professional's plays an important role in our society. They work hard and served the nation during pandemic situation. Anxiety is natural phenomena to every person. So medical professional also feel anxietybut the medical profession demands its professionals to stay cool, calm and free of anxiety by having analytical and cognitive skills, in order to fulfill the needs of their profession. This research helps to understand that ISA has no significant impact on HISB while PT has significant impact on HISB.Copyright © 2023 Lahore Medical And Dental College. All rights reserved.
ABSTRACT
Library patrons have become more interested in sustainability and self-reliance since the start of the COVID-19 pandemic. The programs in this book are written by librarians and sustainability experts who have run these programs themselves. I would recommend this book to library staff who organise events, are interested in sustainable living programs, and who would like to help their communities to learn more sustainable and self-reliance skills.

ABSTRACT
In an autoethnographic-inspired approach to their Library Student Ambassador Program, Pham and Muralles explore in their case study "Reimagining Peer Support and Engagement,” the growth and development of their program at California State University, East Bay and share recommendations and reflections from their ambassadors. Scripa and Spencer discuss the challenges and successes the team at the Pellissippi State Community College Libraries have had in launching their Pellissippi Ambassadors for Library Success program in "Introducing peer-to-peer reference services in a community college library.” Peer learning as a high impact practice As I and the authors within this issue agree, peer-led programs demonstrate key connecting points to high impact teaching and learning practices, allow opportunities for student employees to engage in career and professional formation activity, enhance a library's ability to engage with and provide outreach to underserved or underrepresented communities and break down traditional power structures, or barriers, that can be created by our traditional service models. In their article, "Shifting to a High Impact Practice-centered Student worker staffed Research Desk: a Hispanic Serving Institution Perspective,” Elizabeth DeZouche and Denise Santos discuss how their changes to the traditional desk model not only provided student consultants with a meaningful role but also helped them bridge the gap to their campus's mostly Hispanic, first-generation population.
ABSTRACT
Telepractice for people with aphasia (PWA) is gaining importance, not least because of the current SARS-CoV-2 pandemic. Many PWA are affected by a reduction of quality of life (QoL). Experts recommend focussing on psychosocial impacts more consistently, but the transfer to telepractice has been investigated in a limited number of studies so far. The aim of this paper is to examine the impact of different telepractice approaches on QoL in PWA. The evidence was identified through a broad literature research in five databases and other sources such as Google Scholar and referring papers or was searched by hand. In total, twelve studies met the eligibility criteria. Focus of the analysis was the association between therapeutic approaches and their effects on QoL. Half (n = 6) of the included studies clearly indicated positive effects of the applied methods on QoL. Further analysis showed no definable link between the therapeutic approaches and their impact on QoL. Nevertheless, decisive assumptions about QoL-enhancing telepractice can be derived from the literature. Telepractice in aphasia therapy can improve the patients' QoL. Benefits for QoL do not only depend on the utilised approach. Several factors (e.g., enhancing of communicative confidence) are significant in their impact on QoL and should be examined in future research.
ABSTRACT
Objectives: The objective of this study is to assess the clinical benefits and potential risks of using venovenous extracorporeal membrane oxygenation (VV ECMO) as a treatment for COVID-19 patients with severe respiratory failure. Method(s): Relevant studies were identified through searches of electronic databases, including PubMed, EMBASE, and the Cochrane Library, from January 2020 to December 2022. We included observational studies on adult patients who received venovenous (VV) ECMO support for COVID-19-induced ARDS. The primary outcome was in-hospital mortality, 3-month mortality, and complications associated with VV ECMO. Statistical analysis was performed using R version 4.0.3 and the metafor and meta packages. Result(s): The final analysis included 39 studies comprising 10,702 patients. In-hospital mortality for adults receiving ECMO was 34.2% (95% CI: 28.5% - 40.3%;I2 = 93%), while the 3-month mortality rate was 50.2% (95% CI: 44.4% - 56.0%;I2 = 51%). Bleeding requiring transfusion occurred in 33.7% of patients (95% CI, 23.9 - 45.1;I2 = 96%). The pooled estimates for other complications were as follows: overall thromboembolic events 40.9% (95% CI, 24.8 - 59.3;I2 = 97%), stroke 8.7% (95% CI, 5.7 - 13.2;I2 = 72%), deep vein thrombosis 15.4% (95% CI, 9.7 - 23.6;I2 = 80%), pulmonary embolism 15.6% (95% CI, 9.3 - 25.1;I2 = 92%), gastrointestinal haemorrhage 8.1% (95% CI, 5.5 - 11.8;I2 = 56%), and the need for any renal replacement therapy in 38.0% of patients (95% CI, 31.6 - 44.8;I2 = 84%). Bacterial pneumonia occurred in 46.4% of patients (95% CI, 32.5 - 61.0;I2 = 96%). Conclusion(s): Venovenous extracorporeal membrane oxygenation (VV ECMO) may be an effective treatment option for COVID-19 patients with severe respiratory failure. The use of VV ECMO was associated with reduced in-hospital and 3-month mortality. However, bleeding is a common complication that should be closely monitored. Further research is needed to determine the optimal use of VV ECMO in this patient population and to identify factors that may predict a favourable response to treatment.
ABSTRACT
Objectives: The aim of this systematic review and metaanalysis was to evaluate the effectiveness of ECMO in pediatric COVID-19 patients in terms of mortality rate, rate of successful weaning, and frequency of complications. Method(s): A comprehensive search of electronic databases including PubMed, Cochrane Library, and EMBASE was conducted to identify relevant studies published up to December 2022. Inclusion criteria for the studies included observational studies and case series with a minimum of five patients that reported on the use of ECMO in children with COVID-19. Statistical analysis was performed using R version 4.0.3 and the metafor and meta packages. Result(s): Seven studies involving a total of 73 pediatric COVID-19 patients who received ECMO were identified. The pooled estimate of mortality in children receiving ECMO was 21.5% (15 out of 73 patients;95% CI: 9.9% to 40.5%;I2 = 14%). The success rate for weaning off/decannulation of ECMO was estimated to be 85.1% (52 out of 61 patients;95% CI, 67.8-93.9;I2 = 1%). The overall complication rate was 32.6% (14 out of 43;95% CI, 20.3-47.7;I2 = 0%). Conclusion(s): The results of this systematic review and meta-analysis indicate that ECMO may be an effective treatment option for children with severe COVID-19, particularly those requiring mechanical ventilation. The success rate for weaning off/decannulation of ECMO was estimated to be 85.1%, while the overall complication rate was 32.6%. However, the small sample size and high risk of bias in the included studies should be taken into consideration when interpreting these results. Further research is necessary to confirm the efficacy of ECMO in pediatric COVID-19 patients and determine the optimal use of this treatment.
ABSTRACT
Objectives: Meta-analyses have investigated associations between race and ethnicity and COVID-19 outcomes. However, there is uncertainty about these associations' existence, magnitude, and level of evidence. We, therefore, aimed to synthesize, quantify, and grade the strength of evidence of race and ethnicity and COVID-19 outcomes in the US. Method(s): In this umbrella review, we searched four databases (Pubmed, Embase, the Cochrane Database of Systematic Reviews, and Epistemonikos) from database inception to April 2022. The methodological quality of each meta-analysis was assessed using the Assessment of Multiple Systematic Reviews, version 2 (AMSTAR-2). The strength of evidence of the associations between race and ethnicity with outcomes was ranked according to established criteria as convincing, highly suggestive, suggestive, weak, or non-significant. The study protocol was registered with PROSPERO, CRD42022336805 Results: Of 880 records screened, we selected seven meta-analyses for evidence synthesis, with 42 associations examined. Overall, 10 of 42 associations were statistically significant (p <= 0.05). Two associations were highly suggestive, two were suggestive, and two were weak, whereas the remaining 32 associations were non-significant. The risk of COVID-19 infection was higher in Black individuals compared to White individuals (risk ratio, 2.08, 95% Confidence Interval (CI), 1.60-2.71), which was supported by highly suggestive evidence;with the conservative estimates from the sensitivity analyses, this association remained suggestive. Among those infected with COVID-19, Hispanic individuals had a higher risk of COVID-19 hospitalization than non-Hispanic White individuals (odds ratio, 2.08, 95% CI, 1.60-2.70) with highly suggestive evidence which remained after sensitivity analyses. Conclusion(s): Individuals of Black and Hispanic groups had a higher risk of COVID-19 infection and hospitalization. These associations of race and ethnicity and COVID-19 outcomes existed more obviously in the pre-hospitalization stage. More consideration should be given in this stage for addressing health inequity.Copyright © 2023
