Spatio-temporal distribution of AOD and its response to regional energy consumption and air pollution factors in China

Author(s): Su Y; Chen X; Guo J; Yang A;

Aerosols serve as crucial indicators of air pollution assessment, and exert significant effects on climate change, ecological environment, and human health. However, the relationship between energy consumption, a significant contributor to air pollution, and aerosols in different economic development zones in China remains understudied. This paper employs ...

Distinguishing Between Healthy and Unhealthy Newborns Based on Acoustic Features and Deep Learning Neural Networks Tuned by Bayesian Optimization and Random Search Algorithm

Author(s): Lahmiri S; Tadj C; Gargour C;

Voice analysis and classification for biomedical diagnosis purpose is receiving a growing attention to assist physicians in the decision-making process in clinical milieu. In this study, we develop and test deep feedforward neural networks (DFFNN) to distinguish between healthy and unhealthy newborns. The DFFNN are trained with acoustic features measured ...

Biotuner: A python toolbox integrating music theory and signal processing for harmonic analysis of physiological and natural time series

Author(s): Bellemare-Pepin A; Jerbi K;

Background: The Biotuner Toolbox is an open-source Python toolbox for biosignals that integrates concepts from neuroscience, music theory, and signal processing. It introduces a harmonic perspective on physiological oscillations by applying musical constructs such as consonance, rhythm, and scale construction. Methods: The core biotuner_object processes ...

Temporal and Sex-Related Differences in Knee Biomechanics Over the Course of the Varsity Athletic Season: Pre- and Postseason Knee Kinematics in Collegiate Varsity Athletes Using Kinect

Author(s): Joseph T; Babouras A; Zhao KY; Corban J; Martineau PA;

Background: Anterior cruciate ligament (ACL) tears can be a source of significant morbidity, with the potential for career-altering implications for athletes who sustain them. Specific knee biomechanics during a drop vertical jump have been shown to be associated with an increased risk for ACL injury in collegiate varsity athletes. Presently, the evolutio ...

Robust and Compact Electrostatic Comb Drive Arrays for High-Performance Monolithic Silicon Photonics

Author(s): Fasihanifard M; Packirisamy M;

Actuating monolithic photonic components (particularly slab waveguides) requires higher force due to their inherent stiffness. However, two primary constraints must be addressed: actuator footprint and fabrication limits. Increasing the number of fingers to provide the required force is not a viable solution due to space constraints, and we must also adhe ...

Syngap1 regulates the synaptic drive and membrane excitability of Parvalbumin-positive interneurons in mouse auditory cortex

Author(s): Francavilla R; Chattopadhyaya B; Damo Kamda JL; Jadhav V; Kourrich S; Michaud JL; Di Cristo G;

SYNGAP1 haploinsufficiency-related intellectual disability (SYNGAP1-ID) is characterized by moderate to severe ID, generalized epilepsy, autism spectrum disorder, sensory processing dysfunction, and other behavioral abnormalities. While numerous studies have highlighted a role of Syngap1 in corti ...

Artificial intelligence-assisted identification of condensing osteitis and idiopathic osteosclerosis on panoramic radiographs

Author(s): Yuksel IB; Boudesh A; Ghanbarzadehchaleshtori M; Ozsoy SC; Bahrilli S; Mohammadi R; Altindag A;

Idiopathic osteosclerosis (IOS) and condensing osteitis (CO) represent radiopaque lesions often detected incidentally within the jaws, posing substantial diagnostic challenges due to their overlapping radiographic characteristics. The objective of this study was to assess the diagnostic efficacy ...

Disentangling prediction error and value in a formal test of dopamine s role in reinforcement learning

Author(s): Usypchuk AA; Maes EJP; Lozzi M; Avramidis DK; Schoenbaum G; Esber GR; Gardner MPH; Iordanova MD;

The discovery that midbrain dopamine (DA) transients can be mapped onto reward prediction errors (RPEs), the critical signal that drives learning, is a landmark in neuroscience. Causal support for the RPE hypothesis comes from studies showing that stimulating DA neurons can drive learning under c ...

Variations in perfusion detectable in advance of microstructure in white matter aging

Author(s): Robinson TD; Sun YL; Chang PTH; Gauthier CJ; Chen JJ;

One of the most promising interventional targets for brain health is cerebral perfusion, but its link to white matter (WM) aging remains unclear. Motivated by existing literature demonstrating links between declining cortical perfusion and the development of WM hyperintensities, we posit that regional WM hypoperfusion precedes deteriorating WM integrity. ...

Deformable detection transformers for domain adaptable ultrasound localization microscopy with robustness to point spread function variations

Author(s): Gharamaleki SK; Helfield B; Rivaz H;

Super-resolution imaging has emerged as a rapidly advancing field in diagnostic ultrasound. Ultrasound Localization Microscopy (ULM) achieves sub-wavelength precision in microvasculature imaging by tracking gas microbubbles (MBs) flowing through blood vessels. However, MB localization faces challenges due to dynamic point spread functions (PSFs) caused by ...

Application of machine learning for predicting the incubation period of water droplet erosion in metals

Author(s): AlHammad K; Medraj M; Tembely M;

Water droplet erosion (WDE) is a critical degradation phenomenon that significantly affects component lifespan and performance in power generation, aerospace, and wind energy industries. The incubation period-the initial phase before visible material loss occurs-is particularly crucial for maintenance planning and material selection yet remains challengin ...
