Facial length and angle feature recognition for digital libraries.

With the continuous progress of technology, facial recognition technology is widely used in various scenarios as a mature biometric technology. However, the accuracy of facial feature recognition has become a major challenge. This study proposes a face length feature and angle feature recognition method for digital libraries, targeting the recognition of different facial features. Firstly, an in-depth study is conducted on the architecture of facial action networks based on attention mechanisms to provide more accurate and comprehensive facial features. Secondly, a network architecture based on length and angle features of facial expressions, the expression recognition network is explored to improve the recognition rate of different expressions. Finally, an end-to-end network framework based on attention mechanism for facial feature points is constructed to improve the accuracy and stability of facial feature recognition network. To verify the effectiveness of the proposed method, experiments were conducted using the facial expression dataset FER-2013. The experimental results showed that the average recognition rate for the seven common expressions was 97.28% to 99.97%. The highest recognition rate for happiness and surprise was 99.97%, while the relatively low recognition rate for anger, fear, and neutrality was 97.18%. The data has verified that the research method can effectively recognize and distinguish different facial expressions, with high accuracy and robustness. The recognition method based on attention mechanism for facial feature points has effectively optimized the recognition process of facial length and angle features, significantly improving the stability of facial expression recognition, especially in complex environments, providing reliable technical support for digital libraries and other fields. This study aims to promote the development of facial recognition technology in digital libraries, improve the service quality and user experience of digital libraries.

Comunicação de más notícias em cuidados paliativos: estudo bibliométrico / Communication of bad news in palliative care: bibliometric study / Comunicación de malas noticias en cuidados paliativos: estudio bibliométrico

Os cuidados paliativos compreendem a melhora da qualidade de vida e o alívio dos sintomas de pacientes que enfrentam doenças que ameaçam a continuidade da vida e de seus familiares. Para tal, é necessário habilidade comunicativa, a fim de uma boa condução ao transmitir uma má notícia. Buscou-se compreender como se configura a produção científica nacional e internacional que aborda a comunicação de más notícias em cuidados paliativos. A pesquisa de revisão, de análise bibliométrica, analisou 25 artigos dos últimos cinco anos (entre 2016 e 2020) disponíveis na Biblioteca Virtual em Saúde (BVS/Bireme). Os resultados revelaram publicações de 134 autores em 16 periódicos de diferentes países. Parte dos estudos foi realizadacom profissionais de saúde em hospitais e apresentam abordagem quantitativa. A comunicação de más notícias ainda se mostra um desafio para profissionais, pacientes e familiares.

The palliative care comprises improving the quality of life and relieving the symptoms of patients facing illnesses that threaten the continuity of life and their families. For this, communicative ability is necessary, in order to conduct well when transmitting bad news. We sought to understand how the national and international scientific production on communication of bad news in palliative care is configured. The literature review research, based on bibliometrics, analysed 25 articles from the last five years (between 2016 and 2020) available in the Virtual Health Library (BVS/Bireme).

The Performance of Wearable AI in Detecting Stress Among Students: Systematic Review and Meta-Analysis.

BACKGROUND: Students usually encounter stress throughout their academic path. Ongoing stressors may lead to chronic stress, adversely affecting their physical and mental well-being. Thus, early detection and monitoring of stress among students are crucial. Wearable artificial intelligence (AI) has emerged as a valuable tool for this purpose. It offers an objective, noninvasive, nonobtrusive, automated approach to continuously monitor biomarkers in real time, thereby addressing the limitations of traditional approaches such as self-reported questionnaires. OBJECTIVE: This systematic review and meta-analysis aim to assess the performance of wearable AI in detecting and predicting stress among students. METHODS: Search sources in this review included 7 electronic databases (MEDLINE, Embase, PsycINFO, ACM Digital Library, Scopus, IEEE Xplore, and Google Scholar). We also checked the reference lists of the included studies and checked studies that cited the included studies. The search was conducted on June 12, 2023. This review included research articles centered on the creation or application of AI algorithms for the detection or prediction of stress among students using data from wearable devices. In total, 2 independent reviewers performed study selection, data extraction, and risk-of-bias assessment. The Quality Assessment of Diagnostic Accuracy Studies-Revised tool was adapted and used to examine the risk of bias in the included studies. Evidence synthesis was conducted using narrative and statistical techniques. RESULTS: This review included 5.8% (19/327) of the studies retrieved from the search sources. A meta-analysis of 37 accuracy estimates derived from 32% (6/19) of the studies revealed a pooled mean accuracy of 0.856 (95% CI 0.70-0.93). Subgroup analyses demonstrated that the accuracy of wearable AI was moderated by the number of stress classes (P=.02), type of wearable device (P=.049), location of the wearable device (P=.02), data set size (P=.009), and ground truth (P=.001). The average estimates of sensitivity, specificity, and F1-score were 0.755 (SD 0.181), 0.744 (SD 0.147), and 0.759 (SD 0.139), respectively. CONCLUSIONS: Wearable AI shows promise in detecting student stress but currently has suboptimal performance. The results of the subgroup analyses should be carefully interpreted given that many of these findings may be due to other confounding factors rather than the underlying grouping characteristics. Thus, wearable AI should be used alongside other assessments (eg, clinical questionnaires) until further evidence is available. Future research should explore the ability of wearable AI to differentiate types of stress, distinguish stress from other mental health issues, predict future occurrences of stress, consider factors such as the placement of the wearable device and the methods used to assess the ground truth, and report detailed results to facilitate the conduct of meta-analyses.

Biblioteca virtual em saúde homeopatia Brasil Dr. Matheus Marim: o ingresso da homeopatia na literatura científica mundial / Virtual library in health homeopathy Brazil Dr. Matheus Marim: the entrance of homeopathy in scientific literature worldwide

A Biblioteca Virtual em Saúde (BVS) Homeopatia Brasil(1) personifica o ingresso da Homeopatia na literatura médica oficial, sendo o resultado de décadas de um trabalho voluntário de vários homeopatas, tendo uma história de mais 40 anos a qual se mescla de maneira indissociável com a história da Biblioteca Regional de Medicina (BIREME)(2), que adotou posteriormente o nome de Centro Latino-Americano e do Caribe de Informação em Ciências da Saúde(3). É também um testemunho da transformação tecnológica do paradigma das bibliotecas físicas seculares(4), para as atuais bibliotecas digitais online. A BVS é um patrimônio da Homeopatia brasileira, evidenciando a Homeopatia perante as ciências da saúde como sendo uma especialidade médica em nosso país. Ela teve como marco inicial a base de dados HOMEOINDEX, pioneira e exclusiva da literatura homeopática, construída na década de 90, que será abordada mais adiante. Esta biblioteca virtual homeopática faz parte da rede de bibliotecas virtuais em saúde(5), e da rede BVS Brasil(6) operacionalizadas pela BIREME, órgão regional da OPAS(7) (Organização Panamericana de Saúde) e da OMS(8) (Organização Mundial de Saúde). A BIREME tem como missão contribuir para o desenvolvimento da saúde nos países da América Latina e Caribe por meio da democratização do acesso, publicação e uso de informação, conhecimento e evidência científica. A BIREME abriga atualmente mais de 60 BVSs, entre temáticas, nacionais e regionais, que abordam os mais variados aspectos de informações de cada área, com acesso online eficiente, gratuito, universal e eqüitativo à informação Para entendermos a origem da BVS Homeopatia é necessário que seja abordada também a história da BIREME(9). Desde a sua criação no ano de 1967, a BIREME sempre considerou a colaboração das bibliotecas para desenvolver e oferecer seus serviços e produtos de informação. Nos anos iniciais a primeira tarefa foi o serviço colaborativo de comutação bibliográfica (fornecimento de cópias de documentos), já considerando que apenas a coleção de revistas da então Biblioteca Regional de Medicina não seria suficientemente completa para atender a todos os pedidos dos usuários da América Latina e do Caribe. Os primeiros acordos de cooperação da BIREME com as bibliotecas foram estabelecidos no início dos anos 70, com a Faculdade de Odontologia e a Escola de Medicina Veterinária, ambas da Universidade de São Paulo, com o Instituto de Nutrição da América Central e do Panamá (INCAP), com o Centro Latino-Americano de Perinatologia e Desenvolvimento Humano, e com o Centro Pan-Americano de Engenharia Sanitária e Ciências Ambientais (CEPIS).

The Virtual Health Library (VHL) Homeopathy Brazil embodies the inclusion of Homeopathy in the official medical literature, being the result of decades of voluntary work by several homeopaths, having a history of more than 40 years, which is inseparably intertwined with the history of the Regional Library of Medicine (BIREME), which later adopted the name of the Latin American and Caribbean Center on Health Sciences Information. It is also a testament to the technological transformation from the paradigm of centuries-old physical libraries to today's online digital libraries. The VHL is a heritage of Brazilian Homeopathy, highlighting Homeopathy before the health sciences as a medical specialty in our country. Its initial milestone was the HOMEOINDEX database, a pioneer and exclusive database of homeopathic literature, built in the 1990s, which will be discussed later. This virtual homeopathic library is part of the network of virtual health libraries, and the VHL Brazil network operated by BIREME, a regional body of PAHO (Pan American Health Organization) and WHO (World Health Organization). BIREME's mission is to contribute to the health development in Latin American and Caribbean countries through the democratization of access, publication, and use of information, knowledge, and scientific evidence. BIREME currently houses more than 60 VHLs, including thematic, national, and regional, covering the most varied aspects of information in each area, with efficient, free, universal, and equitable online access to information. To understand the origin of the VHL Homeopathy, it is also necessary to address the history of BIREME. Since its creation in 1967, BIREME has always considered the collaboration of libraries to develop and offer its information services and products. In the early years, the first task was the collaborative bibliographic exchange service (provision of document copies), already considering that the journal collection of the then Regional Library of Medicine would not be sufficiently complete to meet all the requests from users in Latin America and the Caribbean. The first cooperation agreements between BIREME and libraries were established in the early 1970s, with the Faculty of Dentistry and the School of Veterinary Medicine, both from the University of São Paulo, with the Institute of Nutrition of Central America and Panama (INCAP), with the Latin American Center for Perinatology and Human Development, and with the Pan-American Center for Sanitary Engineering and Environmental Sciences (CEPIS).

En la actualidad la capacidad de distinguir cuáles son las fuentes que brindan una información confiable es la herramienta más importante para los investigadores. Por tanto, es necesario profundizar en el uso de fuentes de información veraz y actualizada, y la importancia de evaluarlas. Esta problemática toma mayor fuerza en el área de la salud, por lo que las instituciones en cuestión, se han proyectado en este tipo de estudio. Tal es el caso del Centro Provincial de Información de Ciencias Médicas de Villa Clara, que se propuso evaluar el uso de la Biblioteca Virtual de Salud de Cuba por los bibliotecarios de la red de bibliotecas médicas de la provincia, cuyo objetivo fundamental es satisfacer las necesidades de sus usuarios.

Currently, the ability to distinguish which sources provide reliable information is the most important tool for researchers. Therefore, it is necessary to deepen the use of truthful and updated information sources, and the importance of evaluating them. This problem takes greater importance in the health area, that is why the institutions in question have been projected in this type of study. Such is the case of the Provincial Information Center for Medical Sciences from Villa Clara, which proposed to evaluate the use of the Cuban Virtual Health Library by the librarians of the network of medical libraries in the province, whose fundamental objective is to satisfy the needs of its users.

Integrating Reaction Schemes, Reagent Databases, and Virtual Libraries into Fragment-Based Design by Reinforcement Learning.

Lead optimization supported by artificial intelligence (AI)-based generative models has become increasingly important in drug design. Success factors are reagent availability, novelty, and the optimization of multiple properties. Directed fragment-replacement is particularly attractive, as it mimics medicinal chemistry tactics. Here, we present variations of fragment-based reinforcement learning using an actor-critic model. Novel features include freezing fragments and using reagents as the fragment source. Splitting molecules according to reaction schemes improves synthesizability, while tuning network output probabilities allows us to balance novelty versus diversity. Combining fragment-based optimization with virtual library encodings allows the exploration of large chemical spaces with synthesizable ideas. Collectively, these enhancements influence design toward high-quality molecules with favorable profiles. A validation study using 15 pharmaceutically relevant targets reveals that novel structures are obtained for most cases, which are identical or related to independent validation sets for each target. Hence, these modifications significantly increase the value of fragment-based reinforcement learning for drug design. The code is available on GitHub: https://github.com/Sanofi-Public/IDD-papers-fragrl.

SMiPoly: Generation of a Synthesizable Polymer Virtual Library Using Rule-Based Polymerization Reactions.

Recent advances in machine learning have led to the rapid adoption of various computational methods for de novo molecular design in polymer research, including high-throughput virtual screening and inverse molecular design. In such workflows, molecular generators play an essential role in creation or sequential modification of candidate polymer structures. Machine learning-assisted molecular design has made great technical progress over the past few years. However, the difficulty of identifying synthetic routes to such designed polymers remains unresolved. To address this technical limitation, we present Small Molecules into Polymers (SMiPoly), a Python library for virtual polymer generation that implements 22 chemical rules for commonly applied polymerization reactions. For given small organic molecules to form a candidate monomer set, the SMiPoly generator conducts possible polymerization reactions to generate an exhaustive list of potentially synthesizable polymers. In this study, using 1083 readily available monomers, we generated 169,347 unique polymers forming seven different molecular types: polyolefin, polyester, polyether, polyamide, polyimide, polyurethane, and polyoxazolidone. By comparing the distribution of the virtually created polymers with approximately 16,000 real polymers synthesized so far, it was found that the coverage and novelty of the SMiPoly-generated polymers can reach 48 and 53%, respectively. Incorporating the SMiPoly library into a molecular design workflow will accelerate the process of de novo polymer synthesis by shortening the step to select synthesizable candidate polymers.

Using technology to promote the development of health science libraries in China.

From the point of view of the development of libraries, technology has made possible the emergence and development of library automation; digital libraries; mobile libraries; and smart libraries. This article briefly describes the impact of technological developments and application in Health Science Libraries in China in relation to collections development, service provision and the role of library associations.

Modeling the expansion of virtual screening libraries.

Recently, 'tangible' virtual libraries have made billions of molecules readily available. Prioritizing these molecules for synthesis and testing demands computational approaches, such as docking. Their success may depend on library diversity, their similarity to bio-like molecules and how receptor fit and artifacts change with library size. We compared a library of 3 million 'in-stock' molecules with billion-plus tangible libraries. The bias toward bio-like molecules in the tangible library decreases 19,000-fold versus those 'in-stock'. Similarly, thousands of high-ranking molecules, including experimental actives, from five ultra-large-library docking campaigns are also dissimilar to bio-like molecules. Meanwhile, better-fitting molecules are found as the library grows, with the score improving log-linearly with library size. Finally, as library size increases, so too do rare molecules that rank artifactually well. Although the nature of these artifacts changes from target to target, the expectation of their occurrence does not, and simple strategies can minimize their impact.
