Fine‐Scale Factors Affecting the Abundance and Thermal Sensitivity of Nonnative Brook Trout in Coldwater Rocky Mountain Streams

Fisheries Management and Ecology, EarlyView.
ABSTRACT The Brook Trout (Salvelinus fontinalis) is a globally distributed nonnative species that threatens native salmonids in coldwater streams. Understanding the factors regulating Brook Trout densities in coldwater refugia is critical to effective management, so we investigated (a) fine‐scale drivers of Brook Trout abundance and (b) factors ...

A unified formulation for home healthcare routing and scheduling problems

International Transactions in Operational Research, EarlyView.
Abstract Home Healthcare is an essential component of healthcare systems, where caregivers visit patients' homes to deliver services. While presenting advantages with respect to institutional care, such as being cost‐effective and alleviating family burdens, it presents challenges in scheduling and routing caregivers efficiently.

VNS-induced dose-dependent pupillary response in refractory epilepsy

Purpose: The Locus Coeruleus (LC) plays a vital role by releasing norepinephrine, which contributes to the antiepileptic effects of Vagus Nerve Stimulation (VNS). LC activity also influences pupil dilation.

Freight distribution optimization by implementing the team orienteering problem with occasional drivers

International Transactions in Operational Research, EarlyView.
Abstract This research evaluates the effectiveness of a hybrid crowdshipping system that integrates occasional drivers with traditional delivery services (OD+TD) to improve the efficiency of freight distribution. By implementing the team orienteering problem with occasional drivers model, we develop a mathematical model and an agile optimization ...

Vagal nerve stimulation dynamically alters anxiety-like behavior in rats

Brain Stimulation
Background: Electrical vagal nerve stimulation (VNS), at currents designed to target sensory, interoceptive neurons, decreases anxiety-like behavior. Objective/Hypothesis: We hypothesized that different VNS current intensities would differentially alter ...

An enhanced adaptive large neighborhood search algorithm for the multiple allocation p‐hub location problem with a mesh backbone network in video‐on‐demand services

International Transactions in Operational Research, EarlyView.
Abstract This study tackles the multiple allocation p$p$‐hub location problem (MApHLP) in the context of video‐on‐demand services, where digital content is partitioned into segments and stored exclusively at selected hub locations. Users, distributed across a wide geographical area, can connect to multiple hubs based on demand patterns, with all hubs ...

The effect of vagal nerve stimulation treatment on autonomic nervous system in patients with refractory epilepsy

Frontiers in Neurology
IntroductionVagal nerve stimulation (VNS) is a treatment that can be used in drug-resistant epilepsy (DRE) patients who are not suitable for resective surgery. Effects of VNS on the autonomic system are controversial.
