Ensemble reactivations during brief rest drive fast learning of sequences.

During motor learning, breaks in practice are known to facilitate behavioural optimizations. Although this process has traditionally been studied over long breaks that last hours to days, recent studies in humans have demonstrated that rapid performance gains during early motor sequence learning are most pronounced after very brief breaks lasting seconds to minutes. However, the precise causal neural mechanisms that facilitate performance gains after brief breaks remain poorly understood.

Hand Gesture Recognition for Blind Users by Tracking 3D Gesture Trajectory.

Hand gestures provide an alternate interaction modality for blind users and can be supported using commodity smartwatches without requiring specialized sensors. The enabling technology is an accurate gesture recognition algorithm, but almost all algorithms are designed for sighted users. Our study shows that blind user gestures are considerably diferent from sighted users, rendering current recognition algorithms unsuitable.

Dynamic Statistical Attention-based lightweight model for Retinal Vessel Segmentation: DyStA-RetNet.

Background And Objective: Accurate extraction of retinal vascular components is vital in diagnosing and treating retinal diseases. Achieving precise segmentation of retinal blood vessels is challenging due to their complex structure and overlapping vessels with other anatomical features. Existing deep neural networks often suffer from false positives at vessel branches or missing fragile vessel patterns.

Assessment of egg quality, food safety, and hygiene practices among commercial and non-commercial farms of Barwala district of Panchkula, Haryana.

Background: The aim of the present study was to assess the egg quality, food safety, and hygiene practices in egg production among commercial and non-commercial farms.

Methods: A total of six, each commercial and non-commercial farm, were randomly selected form Barwala district, Panchkula, Haryana, for this study in 2019. A detailed interview on hygiene practices of farm workers was conducted.

Effect of Nicotine Replacement Therapy on Perioperative Pain Management and Opioid Requirement in Abstinent Tobacco Smokers Undergoing Spinal Fusion: A Double-blind Randomized Controlled Trial.

Background: Smoking negatively impacts postoperative outcomes but acute abstinence from smoking during hospitalization can increase postoperative pain, lower pain thresholds, disrupt pain management, and trigger hyperalgesia due to abrupt nicotine withdrawal in tobacco users. Nicotine replacement therapy has been recommended to minimize these complications. We hypothesized that a high dose (21 mg/24 h) transdermal nicotine (TDN) patch would reduce postoperative pain and opioid requirements.
