School of Earth, Environmental, & Marine Sciences Faculty Publications

Roadside exclusionary fencing is commonly used on highways to prevent wildlife-vehicle collisions. Although it can mitigate wildlife road mortality by limiting their access to the road, it can also create a barrier for wildlife stranded within the right-of-way. On State Highway 100 in Texas, the Texas Department of Transportation installed 10 wildlife exits (WEs) to allow endangered ocelots and other wildlife to escape the fenced roadway and minimize wildlife-vehicle collisions. Our study compared three types of WE designs within the same area from 2019 to 2024 to assess their effectiveness. The first design (Design A) was without a door and …

Autistic Traits In Fibromyalgia Are Associated With Hypersensitivity And Central Sensitisation, Helen Johnston, Alison Bacon

School of Psychology

Fibromyalgia presents with symptoms of central sensitisation (CS). Allodynia is the defining symptom, with evidence for general hypersensitisation extending beyond the pain symptoms that characterise fibromyalgia, to sensory and psychological domains. Generalised sensory processing sensitivity (SPS) may increase vulnerability to hypersensitisation; while a direct association exists between sensory sensitivity and autistic traits in autistic people, CS symptoms are also associated with autistic traits in a broader participant sample. This study complements previous lines of enquiry by examining the relationship between SPS, CS symptoms and autistic traits in samples with and without fibromyalgia. It proposes that SPS is indirectly associated with …

2020-Current year OA Pubs

Age-related macular degeneration (AMD) is a leading cause of blindness in people over 50. AMD and cardiovascular disease share risk factors including age, impaired lipid metabolism, and extracellular lipid deposition. Because of its importance in age-related diseases, we hypothesize that apolipoprotein M (ApoM), a lipocalin that binds sphingosine-1-phosphate (S1P), might restore lipid homeostasis and retinal function in AMD. In support, we find that human patients with AMD demonstrate significantly reduced ApoM compared to controls. In mice with impaired retinal cholesterol efflux, ApoM improves retinal pigment epithelium (RPE) function and lipotoxicity in an S1P- and S1P receptor 3-dependent manner. Ultrastructural evidence …

Coarse-Graining Spiking Reservoirs: Reducing Reservoir Size While Preserving Critical Dynamics, Tucker X. Mastin, Christof Teuscher

Northeast Journal of Complex Systems (NEJCS)

We propose an extension of renormalization into the domain of spiking neural networks, thereby providing a novel framework for coarse-graining neural networks without disrupting their critical properties. The proposed coarse-graining technique merges neurons and synaptic connections based on a graph-theoretic distance derived from synaptic weight strength and is configured to effectively prune the reservoir size while preserving the scale-free spiking dynamics indicative of criticality. Criticality in spiking neural networks may provide information-theoretic advantages by optimizing information processing and sensitivity to input. Using time-series prediction benchmarks, we demonstrate that networks operating at criticality exhibit up to 32% higher prediction accuracy before …
