Extended Realities for Sensorially Diverse Children.

-Learning space for children with different sensory needs, nowadays, can be interactive, multisensory experiences, designed collaboratively by (i) specialists in special-needs learning, (ii) Extended Realities (XR)-technologists and (iii) sensorial-diverse children, to provide the motivation, challenge and development of key skills. While traditional audio and visual sensors in XR is challenging for XR-applications to meet the needs of visually and hearing impaired sensorial-diverse children, our research goes a step ahead by integrating sensory technologies including haptic, tactile, kinaesthetic and olfactory feedback that was well received by the children. Our research also demonstrates the protocols for (i) development of a suite of XR-applications; (ii) methods for experiments and evaluation; and (iii) tangible improvements in XR learning experience. Our research considered and is in compliance with the ethical and social implications and has the necessary approval for accessibility, user safety, and privacy.

Virtual reality assessment of a high-calorie food bias: Replication and food-specificity in healthy participants.

BACKGROUND: Theoretical models and behavioural studies indicate faster approach behaviour for high-calorie food (approach bias) among healthy participants. A previous study with Virtual Reality (VR) and online motion-capture quantified this approach bias towards food and non-food cues in a controlled VR environment with hand movements. The aim of this study was to test the specificity of a manual approach bias for high-calorie food in grasp movements compared to low-calorie food and neutral objects of different complexity, namely, simple balls and geometrically more complex office tools. METHODS: In a VR setting, healthy participants (N = 27) repeatedly grasped or pushed high-calorie food, low-calorie food, balls and office tools in randomized order with 30 item repetitions. All objects were rated for valence and arousal. RESULTS: High-calorie food was less attractive and more arousing in subjective ratings than low-calorie food and neutral objects. Movement onset was faster for high-calorie food in push-trials, but overall push responses were comparable. In contrast, responses to high-calorie food relative to low-calorie food and to control objects were faster in grasp trials for later stages of interaction (grasp and collect). Non-parametric tests confirmed an approach bias for high-calorie food. CONCLUSION: A behavioural bias for food was specific to high-calorie food objects. The results confirm the presence of bottom-up advantages in motor-cognitive behaviour for high-calorie food in a non-clinical population. More systematic variations of object fidelity and in clinical populations are outstanding. The utility of VR in assessing approach behaviour is confirmed in this study by exploring manual interactions in a controlled environment.

Playfulness and adolescence: mentalization and neuropsychoanalysis perspective.

The article attempts at conceptualizing the basic principles of how adolescents develop, getting out of childhood and proceeding to enter young adulthood. The age period of adolescence is marked with intense emotional states, lines of thinking, beliefs and transitions that caregivers often face challenges making sense of or mirroring. Combining mentalization-based approaches with neuropsychoanalytic findings about how basic emotional systems governing playful behavior work can shed additional light into the communication channels and specificities therapists might consider when engaging in such endeavor.

Heterogeneous field response of hierarchical polar laminates in relaxor ferroelectrics.

Understanding the microscopic origin of the superior electromechanical response in relaxor ferroelectrics requires knowledge not only of the atomic-scale formation of polar nanodomains (PNDs) but also the rules governing the arrangements and stimulated response of PNDs over longer distances. Using x-ray coherent nanodiffraction, we show the staggered self-assembly of PNDs into unidirectional mesostructures that we refer to as polar laminates in the relaxor ferroelectric 0.68PbMg1/3Nb2/3O3-0.32PbTiO3 (PMN-0.32PT). We reveal the highly heterogeneous electric-field-driven responses of intra- and interlaminate PNDs and establish their correlation with the local strain and the nature of the PND walls. Our observations highlight the critical role of hierarchical lattice organizations on macroscopic material properties and provide guiding principles for the understanding and design of relaxors and a wide range of quantum and functional materials.

Unrecoverable lattice rotation governs structural degradation of single-crystalline cathodes.

Transitioning from polycrystalline to single-crystalline nickel-rich cathodes has garnered considerable attention in both academia and industry, driven by advantages of high tap density and enhanced mechanical properties. However, cathodes with high nickel content (>70%) suffer from substantial capacity degradation, which poses a challenge to their commercial viability. Leveraging multiscale spatial resolution diffraction and imaging techniques, we observe that lattice rotations occur universally in single-crystalline cathodes and play a pivotal role in the structure degradation. These lattice rotations prove unrecoverable and govern the accumulation of adverse lattice distortions over repeated cycles, contributing to structural and mechanical degradation and fast capacity fade. These findings bridge the previous knowledge gap that exists in the mechanistic link between fast performance failure and atomic-scale structure degradation.

The effectiveness of ambulatory continuous popliteal sciatic nerve blockade on patient-reported overall benefit of analgesia in patients undergoing foot or ankle surgery (CAREFREE trial); a randomized, open label, non-inferiority trial.

STUDY OBJECTIVE: Management of pain after foot and ankle surgery remains a concern for patients and healthcare professionals. This study determined the effectiveness of ambulatory continuous popliteal sciatic nerve blockade, compared to standard of care, on overall benefit of analgesia score (OBAS) in patients undergoing foot or ankle surgery. We hypothesized that usage of ambulatory continuous popliteal sciatic nerve blockade is non-inferior to standard of care. DESIGN: Single center, randomized, non-inferiority trial. SETTING: Tertiary hospital in the Netherlands. PATIENTS: Patients were enrolled if ≥18 years and scheduled for elective inpatient foot or ankle surgery. INTERVENTION: Patients were randomized to ambulatory continuous popliteal sciatic nerve blockade or standard of care. MEASUREMENTS: The primary outcome was the difference in OBAS, which includes pain, side effects of analgesics, and patient satisfaction, measured daily from the first to the third day after surgery. A non-inferiority margin of 2 was set as the upper limit for the 90% confidence interval of the difference in OBAS score. Mixed-effects modeling was employed to analyze differences in OBAS scores over time. Secondary outcome was the difference in opioid consumption. MAIN RESULTS: Patients were randomized to standard of care (n = 22), or ambulatory continuous popliteal sciatic nerve blockade (n = 22). Analyzing the first three postoperative days, the OBAS was significantly lower over time in the ambulatory continuous popliteal sciatic nerve blockade group compared to standard of care, demonstrating non-inferiority (-1.9 points, 90% CI -3.1 to -0.7). During the first five postoperative days, patients with ambulatory continuous popliteal sciatic nerve blockade consumed significantly fewer opioids over time compared to standard of care (-8.7 oral morphine milligram equivalents; 95% CI -16.1 to -1.4). CONCLUSIONS: Ambulatory continuous popliteal sciatic nerve blockade is non-inferior to standard of care with single shot popliteal sciatic nerve blockade on patient-reported overall benefit of analgesia.

How to Use and Report on p-values.

The use of the p-value in quantitative research, particularly its threshold of "P < 0.05" for determining "statistical significance," has long been a cornerstone of statistical analysis in research. However, this standard has been increasingly scrutinized for its potential to mislead findings, especially when the practical significance, the number of comparisons, or the suitability of statistical tests are not properly considered. In response to controversy around use of p-values, the American Statistical Association published a statement in 2016 that challenged the research community to abandon the term "statistically significant". This stance has been echoed by leading scientific journals to urge a significant reduction or complete elimination in the reliance on p-values when reporting results. To provide guidance to researchers in health professions education, this paper provides a succinct overview of the ongoing debate regarding the use of p-values and the definition of p-values. It reflects on the controversy by highlighting the common pitfalls associated with p-value interpretation and usage, such as misinterpretation, overemphasis, and false dichotomization between "significant" and "non-significant" results. This paper also outlines specific recommendations for the effective use of p-values in statistical reporting including the importance of reporting effect sizes, confidence intervals, the null hypothesis, and conducting sensitivity analyses for appropriate interpretation. These considerations aim to guide researchers toward a more nuanced and informative use of p-values.

Circumtropical distribution and cryptic species of the meiofaunal enteropneust Meioglossus (Harrimaniidae, Hemichordata).

Hemichordata has always played a central role in evolutionary studies of Chordata due to their close phylogenetic affinity and shared morphological characteristics. Hemichordates had no meiofaunal representatives until the surprising discovery of a microscopic, paedomorphic enteropneust Meioglossus psammophilus (Harrimaniidae, Hemichordata) from the Caribbean in 2012. No additional species have been described since, questioning the broader distribution and significance of this genus. However, being less than a millimeter long and superficially resembling an early juvenile acorn worm, Meioglossus may easily be overlooked in both macrofauna and meiofauna surveys. We here present the discovery of 11 additional populations of Meioglossus from shallow subtropical and tropical coralline sands of the Caribbean Sea, Red Sea, Indian Ocean, and East China Sea. These geographically separated populations show identical morphology but differ genetically. Our phylogenetic reconstructions include four gene markers and support the monophyly of Meioglossus. Species delineation analyses revealed eight new cryptic species, which we herein describe using DNA taxonomy. This study reveals a broad circumtropical distribution, supporting the validity and ecological importance of this enigmatic meiobenthic genus. The high cryptic diversity and apparent morphological stasis of Meioglossus may exemplify a potentially common evolutionary 'dead-end' scenario, where groups with highly miniaturized and simplified body plan lose their ability to diversify morphologically.

The Association of Master Adaptive Learning With Less Burnout and More Resilience in Obstetrics and Gynecology Residents.

PURPOSE: Medical education should prepare learners for complex and evolving work, and should ideally include the Master Adaptive Learner (MAL) model-meta-learning skills for continuous self-regulated learning. This study aimed to measure obstetrics and gynecology (OB/GYN) residents' MAL attributes, assess associations with burnout and resilience, and explore learning task associations with MAL. METHOD: OB/GYN residents were surveyed electronically at an in-training examination in January 2022. The survey included demographic information, the 2-item Maslach Burnout Inventory, the 2-item Connor-Davidson Resilience Scale, 4 MAL items (e.g., "I take every opportunity to learn new things"), and questions about training and learning experiences. RESULTS: Of 5,761 residents, 3,741 respondents (65%) were included. A total of 1,478 of 3,386 (39%) demonstrated burnout (responded positive for burnout on emotional exhaustion or depersonalization items). The mean (SD) Connor-Davidson Resilience Scale score was 6.4 (1.2) of a total possible score of 8. The mean (SD) MAL score was 16.3 (2.8) of a total possible score of 20. The MAL score was inversely associated with burnout, with lower MAL scores for residents with (mean [SD] MAL score, 16.5 [2.4]) vs without (mean [SD], 16.0 [2.3]) burnout (P < .001). Higher MAL scores were associated with higher resilience (R = 0.29, P < .001). Higher MAL scores were associated with the statement, "I feel that I was well prepared for my first year of residency" (R = 0.19, P < .001) and a plan to complete subspecialty training after residency (mean [SD] of 16.6 [2.4] for "yes" and 16.2 [2.4] for "no," P < .001). CONCLUSIONS: Residents who scored higher on MAL showed more resilience and less burnout. Whether less resilient, burned-out residents did not have the agency to achieve MAL status or whether MAL behaviors filled the resiliency reservoir and protected against burnout is not clear.

Atypical Neuroleptic Malignant Syndrome With Type 2 Respiratory Failure Treated With Non-invasive Ventilation.

Neuroleptic malignant syndrome (NMS) is characterized by hyperthermia, severe rigidity, and autonomic instability that is life-threatening if not treated promptly by intensive supportive care. However, there have been numerous reports of "atypical NMS" where the diagnostic criteria of NMS are only partially satisfied. We present a case of an elderly male who presented with atypical NMS secondary to antidopaminergic drug administration which precipitated acute respiratory failure. Our patient exhibited features of severe rigidity and autonomic instability, without hyperthermia. He developed tachypneic hypoventilation with type 2 hypercapneic respiratory failure which was treated with non-invasive ventilation (NIV). The patient recovered after three days with resolution of rigidity and was transferred to a normal medical ward on oxygen via a facemask, where he gradually improved. This study highlights that non-invasive ventilation may have a role in treating respiratory failure in mild to moderate cases of atypical NMS, avoiding the need for intubation.

Promotion in Place: A Model for Competency-Based, Time-Variable Graduate Medical Education.

PROBLEM: Competency-based medical education is increasingly regarded as a preferred framework for physician training, but implementation is limited. U.S. residency programs remain largely time based, with variable assessments and limited opportunities for individualization. Gaps in graduates' readiness for unsupervised care have been noted across specialties. Logistical barriers and regulatory requirements constrain movement toward competency-based, time-variable (CBTV) graduate medical education (GME), despite its theoretical benefits. APPROACH: The authors describe a vision for CBTV-GME and an implementation model that can be applied across specialties. Termed "Promotion in Place" (PIP), the model relies on enhanced assessment, clear criteria for advancement, and flexibility to adjust individuals' responsibilities and time in training based on demonstrated competence. PIP allows a resident's graduation to be advanced or delayed accordingly. Residents deemed competent for early graduation can transition to attending physician status within their training institution and benefit from a period of "sheltered independence" until the standard graduation date. Residents who need extended time to achieve competency have graduation delayed to incorporate additional targeted education. OUTCOMES: A proposal to pilot the PIP model of CBTV-GME received funding through the American Medical Association's "Reimagining Residency" initiative in 2019. Ten of 46 residency programs in a multihospital system expressed interest and pursued initial planning. Seven programs withdrew for reasons including program director transitions, uncertainty about resident reactions, and the COVID-19 pandemic. Three programs petitioned their specialty boards for exemptions from time-based training. One program was granted the needed exemption and launched a PIP pilot, now in year 4, demonstrating the feasibility of implementing this model. Implementation tools and templates are described. NEXT STEPS: Larger-scale implementation with longer-term assessment is needed to evaluate the impact and generalizability of this CBTV-GME model.

Anterior quadratus lumborum catheters for elective cesarean section: A double-blind, randomized, placebo-controlled trial.

BACKGROUND: Optimizing pain management following cesarean section is crucial for the well-being of both mother and infant. Various types of quadratus lumborum blocks have exhibited reduced opioid consumption and pain scores after cesarean section. However, duration of block effect is relatively short. The aim of this study was to investigate the analgesic efficacy of the anterior quadratus lumborum catheters for cesarean section. METHODS: All 32 enrolled participants were allocated to postoperative bilateral ultrasound-guided anterior quadratus lumborum catheter placement with injection of 60 mL ropivacaine 0.375% after cesarean section. Randomization at 2 h resulted in either 60 mL ropivacaine 0.2% or 60 mL isotonic saline injected through the catheters, with subsequent 22-h infusion of either ropivacaine 0.2% or isotonic saline with an infusion rate of 4 mL h-1 per catheter. Participants in the active group received a total of 697 mg ropivacaine during the first 24 h. All participants received the standard postoperative multimodal pain regimen, and a final bilateral injection at 24-h post-catheter placement of 60 mL ropivacaine 0.375% in total. The primary outcome was time to first opioid administration. Secondary outcomes were pain scores, time to first ambulation, nausea and vomiting, accumulated opioid consumption, and catheter displacement rates. RESULTS: No significant intergroup differences were observed following the randomized intervention. Median time to first opioid (IQR) was (active vs. placebo) 414 (283, 597) vs. 428 (245, 552) minutes, with a median difference (CI) of -14 (-184 to 262) min, p = .32. CONCLUSION: Bilateral anterior quadratus lumborum catheters with continuous infusion did not prolong time to first opioid after elective cesarean section.

Optimization of Ketobenzothiazole-Based Type II Transmembrane Serine Protease Inhibitors to Block H1N1 Influenza Virus Replication.

Human influenza viruses cause acute respiratory symptoms that can lead to death. Due to the emergence of antiviral drug-resistant strains, there is an urgent requirement for novel antiviral agents and innovative therapeutic strategies. Using the peptidomimetic ketobenzothiazole protease inhibitor RQAR-Kbt (IN-1, aka N-0100) as a starting point, we report how substituting P2 and P4 positions with natural and unnatural amino acids can modulate the inhibition potency toward matriptase, a prototypical type II transmembrane serine protease (TTSP) that acts as a priming protease for influenza viruses. We also introduced modifications of the peptidomimetics N-terminal groups, leading to significant improvements (from µM to nM, 60 times more potent than IN-1) in their ability to inhibit the replication of influenza H1N1 virus in the Calu-3 cell line derived from human lungs. The selectivity towards other proteases has been evaluated and explained using molecular modeling with a crystal structure recently obtained by our group. By targeting host cell TTSPs as a therapeutic approach, it may be possible to overcome the high mutational rate of influenza viruses and consequently prevent potential drug resistance.

Immunogenicity of BNT162b2 vaccine after two and three doses in health personnel and institutionalized elderly people not infected with SARS-CoV-2.

OBJECTIVE: The aim of our research was to compare the evolution of the immune response induced by the BNT162b2 vaccine after the administration of two and three doses in healthcare personnel and in institutionalized elderly people (>65 years of age) without previous SARS-CoV-2 infection. MATERIAL AND METHODS: A prospective observational study was carried out on a convenience sample made up of health workers and institutionalized elderly people, measuring antibodies against S and N proteins of SARS-CoV-2 two and six months after receiving the second vaccine dose, as well as two months after receiving the third dose. RESULTS: A significant reduction of the anti-S humoral immune response was reported six months after the second dose of vaccine in both health workers and residents. The administration of a third dose of vaccine induced a significant increase in this antibody response in both investigated groups reaching a similar proportion of responders two months after this third dose. CONCLUSIONS: Humoral immunity induced by two doses of the BNT162b2 vaccine in persons without prior SARS-CoV-2 infection wanes over time. The administration of a third dose significantly increases anti-S antibodies being highly recommended, especially in people over 65 years of age.

Modal and amodal cognition: an overarching principle in various domains of psychology.

Accounting for how the human mind represents the internal and external world is a crucial feature of many theories of human cognition. Central to this question is the distinction between modal as opposed to amodal representational formats. It has often been assumed that one but not both of these two types of representations underlie processing in specific domains of cognition (e.g., perception, mental imagery, and language). However, in this paper, we suggest that both formats play a major role in most cognitive domains. We believe that a comprehensive theory of cognition requires a solid understanding of these representational formats and their functional roles within and across different domains of cognition, the developmental trajectory of these representational formats, and their role in dysfunctional behavior. Here we sketch such an overarching perspective that brings together research from diverse subdisciplines of psychology on modal and amodal representational formats so as to unravel their functional principles and their interactions.

Considerations on the Use of Neonatal and Pediatric Resuscitation Guidelines for Hospitalized Neonates and Infants: On Behalf of the American Heart Association Emergency Cardiovascular Care Committee and the American Academy of Pediatrics.

Between 0.25% and 3% of admissions to the NICU, PICU, and PCICU receive cardiopulmonary resuscitation (CPR). Most CPR events occur in patients <1 year old. The incidence of CPR is 10 times higher in the NICU than at birth. Therefore, optimizing the approach to CPR in hospitalized neonates and infants is important. At birth, the resuscitation of newborns is performed according to neonatal resuscitation guidelines. In older infants and children, resuscitation is performed according to pediatric resuscitation guidelines. Neonatal and pediatric guidelines differ in several important ways. There are no published recommendations to guide the transition from neonatal to pediatric guidelines. Therefore, hospitalized neonates and infants can be resuscitated using neonatal guidelines, pediatric guidelines, or a hybrid approach. This report summarizes the current neonatal and pediatric resuscitation guidelines, considers how to apply them to hospitalized neonates and infants, and identifies knowledge gaps and future priorities. The lack of strong scientific data makes it impossible to provide definitive recommendations on when to transition from neonatal to pediatric resuscitation guidelines. Therefore, it is up to health care teams and institutions to decide if neonatal or pediatric guidelines are the best choice in a given location or situation, considering local circumstances, health care team preferences, and resource limitations.

[Emotional well-being, perceptions and attitudes against COVID-19 on adolescents]. / Bienestar emocional, percepciones y actitudes frente a la COVID-19 en adolescentes.

INTRODUCTION: The worldwide pandemic of SARS-Cov2 has had a great impact on the lives of adolescents, affecting their health and well-being. There is little evidence of the emotional impact of the pandemic on adolescents. OBJECTIVE: To explore the knowledge, perceptions, and attitudes of young people regarding COVID-19 and its impact on emotional well-being. METHOD: A cross-sectional observational and descriptive study based on a survey of students aged 16-20 from five high schools in Barcelona metropolitan area. RESULTS: The study was carried out on 291 surveys. Females made up 56.7% of the population. The average age was 16.9 years. A greater lack of knowledge about the transmission of the disease was detected. The most frequently used sources of information were social networks. In terms of emotional distress, the most important aspects were worry about getting sick (64%), family financial problems (46%), anxiety and irritability (27%), and apathy (26.5%). Gender differences were detected in terms of worries (women: 28.8%; men: 11.1%), sadness (women: 29.3%, men: 15.5%), and feelings of fear (women: 24.5%; men: 11%). 16.7% of the participants consulted a mental health professional, with this being more common in women (women: 23.8%; men: 7.4%). CONCLUSIONS: COVID-19 has affected the emotional well-being of adolescents, especially the female population. It is necessary to implement emotional well-being strategies in early childhood to cope with possible stressful situations in daily life and avoid future mental health problems. There is a growing use of social media to combat social isolation. The results of the study hold the potential to strategies aimed at preempting forthcoming biopsychosocial distress.

The high biodiversity of benthic organisms in a coastal ecosystem revealed by an integrative approach / A alta biodiversidade de organismos bentônicos em um ecossistema costeiro revelada por uma abordagem integrativa

Abstract Increasing habitat modification and species loss demand consistent efforts to describe and understand biodiversity patterns. The BIOTA/FAPESP Program was created in this context and it has been a successful initiative to promote studies on biodiversity and conservation in Brazil. The BIOTA/Araçá is an interdisciplinary project that provided a detailed evaluation of the biodiversity of Araçá Bay, a coastal seascape located on the North coast of the state of São Paulo, Southeast Brazil. The bay encompasses multiple habitats, such as beaches, mangroves, rocky shores, and a tidal flat, and provides important ecosystem services. Unfortunately, the bay is the subject of complex social-environmental conflicts that oppose economic, social, and environmental demands (i.e., the expansion of neighboring harbor activities vs. small-scale artisanal fisheries and protection of biodiversity). The present study presents a survey of the benthic species occurring in the different habitats of Araçá Bay, including data obtained during the BIOTA/Araçá project and previous assessments of the area. The benthic species play an important role in marine environments and studying the diversity of these organisms that live associated with the bottom is indispensable for comprehending the environment's functioning. The macrofauna, meiofauna, and microorganisms associated with soft and hard bottom were listed, and additional information, such as the habitat and geographical distribution, were provided for each species. The checklist includes 826 species, almost 70% recorded during the BIOTA/Araçá project. The most speciose taxa were the annelids (225 spp.), mollusks (194 spp.), and crustaceans (177 spp.). Seven benthic species are endemic to Araçá Bay, 14 are considered threatened, and seven are economically exploited. Furthermore, the bay is the type locality of many taxa, and 11 new benthic species were described based on specimens sampled during the project. This project shows the importance of Araçá Bay as a unique biologically rich environment and highlights the need for conservation efforts in light of the current threats.

Resumo O aumento da modificação dos habitats e da perda de espécies demanda esforços consistentes para descrever e compreender os padrões de biodiversidade. O programa BIOTA/FAPESP foi criado nesse contexto e é uma iniciativa de sucesso para promover estudos em biodiversidade e conservação no Brasil. O BIOTA/Araçá é um projeto interdisciplinar que promoveu uma avaliação detalhada da biodiversidade da Baía do Araçá, um ecossistema costeiro localizado ao Norte do estado de São Paulo, Sudeste do Brasil. A baía engloba múltiplos habitats, tais como praias, manguezais, costões rochosos, e uma planície de maré, e também fornece importantes serviços ecossistêmicos. Infelizmente, a baía está sujeita à conflitos sócio-ambientais complexos que contrastam demandas econômicas, sociais e ambientais (i.e. a expansão das atividades do porto vizinho vs. a pesca artesanal de pequena escala e a proteção da biodiversidade). O presente estudo apresenta um levantamento das espécies bentônicas que ocorrem nos diferentes habitats da Baía do Araçá, incluindo dados obtidos durante o projeto BIOTA/Araçá e de investigações realizadas anteriormente na área. As espécies bentônicas desempenham um papel importante no ambiente marinho, e estudar a diversidade desses organismos que vivem associados ao fundo é indispensável para compreender o funcionamento do meio ambiente. A macrofauna, meiofauna, e microorganismos associados aos fundos consolidado e inconsolidado foram listados, e informações adicionais foram fornecidas para cada espécie, tais como a distribuição geográfica e nos habitats. O checklist inclui 826 espécies, quase 70% registradas durante o projeto BIOTA/Araçá. Os taxa mais especiosos foram os anelídeos (225 spp.), moluscos (194 spp.), e crustáceos (177 spp.). Entre as espécies bentônicas listadas, sete são endêmicas da Baía do Araçá, 14 são consideradas ameaçadas de extinção, e sete são exploradas economicamente. A baía é a localidade tipo de vários taxa, e 11 novas espécies bentônicas foram descritas com base em espécimes amostrados durante o projeto. Este projeto mostra a importância da Baía do Araçá como um ambiente de riqueza biológica única e demonstra a necessidade de esforços para a sua conservação considerando as atuais ameaças.

Deep learning at the edge enables real-time streaming ptychographic imaging.

Coherent imaging techniques provide an unparalleled multi-scale view of materials across scientific and technological fields, from structural materials to quantum devices, from integrated circuits to biological cells. Driven by the construction of brighter sources and high-rate detectors, coherent imaging methods like ptychography are poised to revolutionize nanoscale materials characterization. However, these advancements are accompanied by significant increase in data and compute needs, which precludes real-time imaging, feedback and decision-making capabilities with conventional approaches. Here, we demonstrate a workflow that leverages artificial intelligence at the edge and high-performance computing to enable real-time inversion on X-ray ptychography data streamed directly from a detector at up to 2 kHz. The proposed AI-enabled workflow eliminates the oversampling constraints, allowing low-dose imaging using orders of magnitude less data than required by traditional methods.
