Exploring Photoreceptor Gene Expression and Seasonal Physiology in Mediterranean Swordfish ().

Mature and immature female swordfish show different gonadal expression patterns of melatonin synthesis-related and opsin genes, indicating that seasonality affects gonadal circadian genes, especially through opsin modulation. The high energy demands of reproduction may cause mature female swordfish to become more susceptible to environmental stressors/changes, potentially affecting their health post-reproduction. The modulation of melatonin and opsin expression may also influence swordfish biology, impacting basal metabolism and stress responses.

Efficient Hyperdimensional Computing With Spiking Phasors.

Hyperdimensional (HD) computing (also referred to as vector symbolic architectures, VSAs) offers a method for encoding symbols into vectors, allowing for those symbols to be combined in different ways to form other vectors in the same vector space. The vectors and operators form a compositional algebra, such that composite vectors can be decomposed back to their constituent vectors. Many useful algorithms have implementations in HD computing, such as classification, spatial navigation, language modeling, and logic.

Distinguishing motion artifacts during optical fiber-based hemodynamics recordings from brain regions of freely moving rodents.

Significance: Motion artifacts in the signals recorded during optical fiber-based measurements can lead to misinterpretation of data. In this work, we address this problem during rodent experiments and develop a motion artifacts correction (MAC) algorithm for single-fiber system (SFS) hemodynamics measurements from the brains of rodents.

Aim: (i) To distinguish the effect of motion artifacts in the SFS signals.

A Pilot Study in Fatigue Risk Management Among Obstetrics and Gynaecology Residents at the University of Alberta.

Objectives: Combatting fatigue is an ongoing challenge in surgical residency programs impacting both patient care and resident well-being. There is a gap in understanding the nuances of fatigue perpetuation, especially where it relates to specific on-call duties. This pilot study seeks to explore the extent of sleep deprivation among Obstetrics and Gynecology (OBGYN) residents and identify obstacles to obtaining adequate rest.

Hypothalamic CRH neurons represent physiological memory of positive and negative experience.

Recalling a salient experience provokes specific behaviors and changes in the physiology or internal state. Relatively little is known about how physiological memories are encoded. We examined the neural substrates of physiological memory by probing CRH neurons of mice, which control the endocrine response to stress.
