A machine learning based investigation of void distribution effects in ductile failure

The overarching goal of this work is to develop a predictive model of fracture resistance in a context of epistemic uncertainty due to analytically intractable mechanisms in metallic materials. The uncertainty associated with the spatial distribution of defects, such as voids, an...

PS1-19. Effects of CIDR-induced Vaginitis and/or Estrus Expression on Ex Vivo Semen Performance When Exposed to Vaginal Fluid.

Abstract Estrus synchronization protocols using CIDR can induce vaginitis in a substantial proportion of treated females, potentially altering the vaginal environment encountered by sperm at artificial insemination. Our objective was to determine whether vaginal fluid from cows e...

Presumptive necrotising fasciitis with concurrent pyothorax in a 9‐month‐old Great Dane

Abstract A 9‐month‐old, entire, male Great Dane presented with rapid multi‐limb swelling, pyrexia and diarrhea following initial treatment for presumed gastroenteritis. Diagnostic evaluation revealed septic pleuropneumonia concurrent with rapidly progressive soft tissue infection...

The Importance and Rarity of Spatial Replication in Landscape Genetics

Abstract Purpose of Review Conserving ecological connectivity is important for maintaining resilient and genetically diverse populations. Landscape genetic analyses represent a powerful tool to help model connectivity for conservation, but there exist risks in improper extrapolat...

A FRET-Based Fluorometric Assay for Tracking the Enzymatic Degradation of Poly- l -Lactic Acid

Abstract Protein engineering has recently emerged as a promising strategy for enhancing the enzymatic recycling of bio-based polymers with the aim of replacing non-degradable petroleum-based plastics with biodegradable ones like poly-l-lactic acid (PLLA). However, a significant c...

Review of nematode interactions with hemp (Cannabis sativa)

. Literature on the impact of root-associated chemicals on plant parasitic nematodes was also searched; in cases where there were no reports, impacts on free-living or animal parasitic nematodes were discussed.

Examining Gender Differences in the Link Between Impulsivity and Digital Dating Abuse

Digital dating abuse (DDA), a form of online intimate partner violence, has emerged as a prevalent behavioral health concern among college students. This study examined the role of impulsivity and gender in predicting DDA perpetration, as well as whether gender (i.e., woman or ma...

The Hazing Program Assessment (HPA): validation of a brief measure of hazing knowledge, confidence, and beliefs

Objective: To develop and validate the Hazing Program Assessment (HPA), a brief instrument designed to assess hazing knowledge, confidence, and beliefs among college students participating in hazing prevention programs. Participants: Participants included 1,697 college students a...

Engineering Metrics for Full-Scale Viability of PFAS Sorbent Regeneration

Abstract Evolving global regulations of per- and polyfluoroalkyl substances (PFASs) are driving rapid expansion of sorbent-based treatment in drinking water and industrial effluents. Granular activated carbon and anion-exchange resins remain among the best available technologies,...

Explainable AI and ethical information practices in library services

Purpose This conceptual paper aims to examine the concept of explainable artificial intelligence (XAI) as a tool for maintaining information ethics in the context of library services. It investigates the importance of XAI in the context of artificial intelligence (AI) and respons...

Past rapid spread of introduced livestock coincided with vegetation clearance on Madagascar

Debates persist around the past and present effects of introduced livestock on the native biodiversity of Madagascar. Indeed, the variable habitat and past rate of spread of livestock across the island's distinct ecoregions are poorly known. Sets of 14C and stable isotope data fr...

Photoreactive Pantetheinyl Mimics Reveal Design Limitations for Crypto‐Acyl Carrier Proteins

Polyketide synthases (PKS), fatty acid synthases (FAS), and non-ribosomal peptide synthetases (NRPS) span a variety of protein architectures and catalytic modalities. Common to all these biosynthetic modalities is the centrality of a phosphopantetheinylated carrier protein, which...

Frequency-dependent shear and bulk viscosity of aqueous and non-aqueous lithium battery electrolytes

Transverse ultrasound was used to examine the frequency-dependent shear viscosities of three lithium bis(trifluoromethanesulfonyl)imide-based electrolytes: aqueous, non-aqueous, and hybrid aqueous-organic solutions. Frequency-dependent bulk viscosities of two of the electrolytes...

W1. POSTPARTUM STRESS CAUSES TRANSCRIPTOMIC AND EPITRANSCRIPTOMIC CHANGES IN THE BASOLATERAL AMYGDALA OF RAT DAMS

Background Maternal postpartum stress caused by low resource parenting can produce enduring affective and stress-reactivity phenotypes in offspring, yet the effects on the maternal brain are largely unexplored. We aimed to define how postpartum stress reshapes isoform usage and t...

ThermoPix: an electronic-photonic temperature sensor array with microsecond row readout

Abstract This paper presents ThermoPix, a CMOS-compatible electronic–photonic architecture for high-spatial-resolution temperature sensing. The proposed system converts temperature-induced wavelength shifts in a photonic interferometric sensor into timing information that can be...

Hallucinations in organization-backed AI advisors: Evidence about skepticism, verification, and reliance in goal-directed use

Generative artificial intelligence (GenAI) systems are increasingly used by organizations to deliver information to consumers, patients, students, employees, and citizens. These systems can hallucinate, producing plausible but inaccurate responses. A central question for AI-advis...

Proteomics and characterization of lignocellulosic carbohydrate utilization for Thermoanaerobacterium thermosaccharolyticum reveals two thermophilic Gram-positive polysaccharide utilization loci

Saccharolytic bacteria are of increasing interest due to their importance in human health and the environment. In particular, their abilities to utilize diverse plant polysaccharides make them attractive candidate organisms for production of lignocellulosic biofuels. Thermoanaero...

Factors influencing veterinary student interest in equine practice in the United States: A focus group study

BACKGROUND: The number of new veterinary graduates entering equine practice in the United States continues to decline, and more than half leave the field within 5 years. Understanding the perspectives of veterinary students is critical for developing interventions that promote re...

Mitochondrial genome-derived microsatellites reveal genetic diversity and population structure in Callery pear populations

Callery pear ( Pyrus calleryana Decne.; PC) possesses many desirable characteristics valued in managed landscapes. This has driven the release of numerous cultivars, including both hybrids and selections derived from native populations. The extensive planting of PC cultivars in m...

Fuel cycle performance of the Fort Saint Vrain reactor

All modern fuel cycle analysis studies have not considered the historically operated high-enriched uranium (HEU) and thorium (Th) fuel cycles. This represents a significant gap in the literature as these reactors were operated both in the United States and internationally. The wo...
