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 ...

Child and marital stress are associated with a psychophysiological index of self-regulatory capacities among parents of preschool children

Author(s): MacNeil S; da Estrela C; Caldwell W; Gouin JP;

Objective: A parent's ability to self-regulate influences parenting practices. Child-related stressors may deplete parent's self-regulatory capacities. However, this effect may be moderated by the marital context within which stressful parent-child interactions are occurring. The aim of the current study was to investigate the association between ...

Deep learning-based feature discovery for decoding phenotypic plasticity in pediatric high-grade gliomas single-cell transcriptomics

Author(s): Abicumaran Uthamacumaran

Advancements in AI-powered systems medicine have revolutionized biomarker discovery through emergent and explainable features. By use of complex network dynamics and graph-based machine learning, we identified critical determinants of lineage-specific plasticity across the single-cell transcriptomics of pediatric high-grade glioma (pHGGs) subtypes: IDHWT ...

Protocol for evaluating neuronal activity and neurotransmitter release following amyloid-beta oligomer injections into the rat hippocampus

Author(s): Hervé V; Bonenfant L; Amyot M; Balafrej R; Ali OBK; Benali H; Brouillette J;

In Alzheimer's disease, there is an imbalance in neurotransmitter release and altered neuronal activation. Here, we present a protocol approach to analyze neuronal activity by combining local field potential (LFP) recording with microdialysis within the same animal. We describe steps for measuring glutamate and GABA levels following hippocampal amyloi ...

Integration of Membrane-Based Pretreatment Methods with Pressure-Retarded Osmosis for Performance Enhancement: A Review

Author(s): Pakdaman S; Nouri G; Mulligan CN; Nasiri F;

Osmotic energy provides an emerging renewable alternative by leveraging the salinity gradient between two solutions. Among these technologies, pressure-retarded osmosis (PRO) has attracted attention; however, its deployment is hindered by obstacles resulting from impurities in feed and draw solutions and lack of suitable membranes. This review explores th ...

Association between aggression and ADHD polygenic scores and school-age aggression: the mediating role of preschool externalizing behaviors and adverse experiences

Author(s): Bouliane M; Boivin M; Kretschmer T; Lafreniere B; Paquin S; Tremblay R; Côté S; Gouin JP; Andlauer TFM; Petitclerc A; Ouellet-Morin I;

Individual differences in physical aggression (PA) are largely heritable. However, it remains unclear how genetic propensity for aggression manifests early in life and relates to school-age PA. Preschool externalizing behavior problems (EXT) and adverse experiences are known predictors of school- ...

Landscapes-a lens for assessing sustainability

Author(s): Dade MC; Bonn A; Eigenbrod F; Felipe-Lucia MR; Fisher B; Goldstein B; Holland RA; Hopping KA; Lavorel S; Lede Polain Waroux Y; MacDonald GK; Mandle L; Metzger JP; Pascual U; Rieb JT; Vallet A; Wells GJ; Ziter CD; Bennett EM; Robinson BE;

Context: There are urgent calls to transition society to more sustainable trajectories, at scales ranging from local to global. Landscape sustainability (LS), or the capacity for landscapes to provide equitable access to ecosystem services essential for human wellbeing for both current and future ...

iSurgARy: A mobile augmented reality solution for ventriculostomy in resource-limited settings

Author(s): Asadi Z; Castillo JP; Asadi M; Sinclair DS; Kersten-Oertel M;

Global disparities in neurosurgical care necessitate innovations addressing affordability and accuracy, particularly for critical procedures like ventriculostomy. This intervention, vital for managing life-threatening intracranial pressure increases, is associated with catheter misplacement rates exceeding 30% when using a freehand technique. Such misplac ...

Deep neural network-based robotic visual servoing for satellite target tracking

Author(s): Ghiasvand S; Xie WF; Mohebbi A;

In response to the costly and error-prone manual satellite tracking on the International Space Station (ISS), this paper presents a deep neural network (DNN)-based robotic visual servoing solution to the automated tracking operation. This innovative approach directly addresses the critical issue of motion decoupling, which poses a significant challenge in ...

Cell Fate Dynamics Reconstruction Identifies TPT1 and PTPRZ1 Feedback Loops as Master Regulators of Differentiation in Pediatric Glioblastoma-Immune Cell Networks

Author(s): Abicumaran Uthamacumaran

Pediatric glioblastoma is a complex dynamical disease that is difficult to treat due to its multiple adaptive behaviors driven largely by phenotypic plasticity. Integrated data science and network theory pipelines offer novel approaches to studying glioblastoma cell fate dynamics, particularly phenotypic transitions over time. Here we used various single- ...

Challenges and Approaches in the Study of Neural Entrainment

Author(s): Duecker K; Doelling KB; Breska A; Coffey EBJ; Sivarao DV; Zoefel B;

When exposed to rhythmic stimulation, the human brain displays rhythmic activity across sensory modalities and regions. Given the ubiquity of this phenomenon, how sensory rhythms are transformed into neural rhythms remains surprisingly inconclusive. An influential model posits that endogenous oscillations entrain to external rhythms, thereby encoding envi ...
