Sensors, Vol. 24, Pages 2620: Emotion Classification Based on Pulsatile Images Extracted from Short Facial Videos via Deep Learning
This study improves an emotion classification approach developed in a previous study, which classifies emotions remotely without relying on stereotypical facial expressions or contact-based methods, using short facial video data. In this approach, we desire to remotely sense transdermal cardiovascular spatiotemporal facial patterns associated with different emotional states and analyze this data via machine learning. In this paper, we propose several improvements, which include a better remote heart rate estimation via a preliminary skin segmentation, improvement of the heartbeat peaks and troughs detection process, and ob...

Sensors, Vol. 24, Pages 2616: Structural Damage Detection Based on the Correlation of Variational Autoencoder Neural Networks Using Limited Sensors
Ma
Identifying the structural state without baseline data is an important engineering problem in the field of structural health monitoring, which is crucial for assessing the safety condition of structures. In the context of limited accelerometers available, this paper proposes a correlation-based damage identification method using Variational Autoencoder neural networks. The approach involves initially constructing a Variational Autoencoder network model for bridge damage detection, optimizing parameters such as loss functions and learning rates for the model, and ultimately utilizing response data from limited senso...

Sensors, Vol. 24, Pages 2611: A Post-Processing Multipath/NLoS Bias Estimation Method Based on DBSCAN
o Dovis
Positioning based on Global Navigation Satellite Systems (GNSSs) in urban environments always suffers from multipath and Non-Line-of-Sight (NLoS) effects. In such conditions, the GNSS pseudorange measurements can be affected by biases disrupting the GNSS-based applications. Many efforts have been devoted to detecting and mitigating the effects of multipath/NLoS, but the identification and classification of such events are still challenging. This research proposes a method for the post-processing estimation of pseudorange biases resulting from multipath/NLoS effects. Providing estimated pseudorange biases due to...

Recontact to return new or updated PALB2 genetic results in the clinical laboratory setting
Conclusion
Novel pathogenic variants in PALB2 were identified in 18 individuals through retrospective gene panel testing. Recontacting these individuals regarding these new or updated findings had a range of outcomes. The process of conveying genomic results within this framework can be effectively accomplished while upholding patient autonomy, potentially leading to advantageous outcomes for patients and their families.

IJERPH, Vol. 21, Pages 503: Intersectional Mentorship in Academic Medicine: A Conceptual Review
owleg
Academic medical institutions seek to recruit and retain a diverse workforce to foster equitable, supportive environments in which early-stage investigators, especially those who are underrepresented in medicine, can thrive. Intersectionality is a critical theoretical framework rooted in Black feminist activism and scholarship that elucidates how power and privilege are differentially structured for groups at different intersectional sociodemographic positions. As a dynamic method of analyzing multiple axes of power and inequality, intersectionality has the potential to offer a critical lens through which to view...

Molecules, Vol. 29, Pages 1857: Binding Mechanism of Inhibitors to BRD4 and BRD9 Decoded by Multiple Independent Molecular Dynamics Simulations and Deep Learning
hong Chen
Bromodomain 4 and 9 (BRD4 and BRD9) have been regarded as important targets of drug designs in regard to the treatment of multiple diseases. In our current study, molecular dynamics (MD) simulations, deep learning (DL) and binding free energy calculations are integrated to probe the binding modes of three inhibitors (H1B, JQ1 and TVU) to BRD4 and BRD9. The MD trajectory-based DL successfully identify significant functional function domains, such as BC-loop and ZA-loop. The information from the post-processing analysis of MD simulations indicates that inhibitor binding highly influences the structural flexibil...

Most People Experiencing Homelessness Have Mental Health Disorders, Study Finds
Sixty-seven percent of people experiencing homelessness worldwide have a mental health disorder, according to areport published yesterday inJAMA Psychiatry. Additionally, the prevalence of mental health disorders among this population appears to be on the rise.“The relationship between mental health disorders and homelessness is complex and bidirectional,” wrote Rebecca Barry, Ph.D., of the University of Calgary and colleagues. “[M]ental health disorders may lead to situations that result in homelessness, or homelessness may be a stressor contributi ng to the development or worsening of mental health disorder symptom...

Daring ‘James Bond’ mission to drill Antarctic ices cores could reveal future of sea level rise
The helicopter hovered overhead, whipping up snow. Shielding his face, Peter Neff grabbed the dangling cargo load and guided it to the Antarctic ice. The helicopter sped back to the South Korean icebreaker
RV Araon
, 20 kilometers away, to fetch more gear. One trip down, 17 more to go,
thought Neff, a polar glaciologist
at the University of Minnesota (UM) Twin Cities. Time was ticking away on this day in January. In the best-case scenario, Neff and his team would have just 10 days to drill ice cores on Canisteo, a peninsula on the west coast of Antarctica—and a blizzard was already looming.

Bisphenol-F and Bisphenol-S (BPF and BPS) Impair the Stemness of Neural Stem Cells and Neuronal Fate Decision in the Hippocampus Leading to Cognitive Dysfunctions
Mol Neurobiol. 2024 Apr 18. doi: 10.1007/s12035-024-04160-1. Online ahead of print.ABSTRACTNeurogenesis occurs throughout life in the hippocampus of the brain, and many environmental toxicants inhibit neural stem cell (NSC) function and neuronal generation. Bisphenol-A (BPA), an endocrine disrupter used for surface coating of plastic products causes injury in the developing and adult brain; thus, many countries have banned its usage in plastic consumer products. BPA analogs/alternatives such as bisphenol-F (BPF) and bisphenol-S (BPS) may also cause neurotoxicity; however, their effects on neurogenesis are still not known. ...
