Behavior of cross-laminated timber panels subjected to contact detonations

This paper presents the results of an experimental test programme on the performance of cross-laminated timber (CLT) panels subjected to contact detonations stemming from live high explosive detonations. Quasi-static three-point bending tests were conducted to establish reference...

Laurentian French vowel laxing: an articulatory and acoustic study

Abstract In Laurentian French (LF), the high vowels /i y u/ are realized as lax [ɪ ʏ ʊ] in syllables closed by certain consonants. Previous work on vowel laxing has focused primarily on describing the environments in which it occurs and on providing an acoustic characterization o...

Risk sharing with lambda value-at-risk under heterogeneous beliefs

Abstract In this paper, we study the risk sharing problem among multiple agents using lambda value-at-risk as their preference functional, under heterogeneous beliefs, where each agent’s belief is represented by a probability measure. We obtain semi-explicit formulas for the inf-...

Exchange: What Can We Learn from Two Decades of Everyday Nationalism?

Abstract In their landmark article on nationalism in the everyday, Jon E. Fox and Cynthia Miller-Idriss (2008a, 537) set out an ambitious research agenda which endeavored to observe “the actual practices through which ordinary people engage and enact (and ignore and deflect) nati...

Muometric Data Modulation and State Synchronization Through Obstructed Subsurface Media: A Theoretical Framework, Channel Physics Model, and Protocol Design

Conventional radio-frequency (RF) and acoustic communication channels suffer severe absorption and scattering when traversing dense rock and collapsed subsurface infrastructure [4, 5]. While relativistic muons (µ ±) possess extreme penetration capabilities, their application as p...

Anomalies in regional cortical morphology and associations with neurocognitive function in children with prenatal cannabis exposure and unexposed comparisons

Prenatal cannabis exposure (PCE) is associated with neurocognitive impairments in childhood, but the underlying neurodevelopmental process remains unclear. In analysis of a subset of data from a prospective cohort of children (age 7–8 years, n = 56) with and without PCE in the US...

Centering equity, diversity and inclusion in environmental evidence synthesis: from awareness to action

Abstract Knowledge generated through evidence synthesis is an approach that decision-makers can take to inform policy and management decisions. Evidence syntheses, such as systematic reviews, provide quantitative and qualitative summaries of this evidence, using structured method...

Investigating acute-to-subacute neuroanatomical outcomes and the role of sex and age in adolescent concussion: A PedCARE+MRI substudy

Background Limited research has examined acute-to-subacute neuroanatomical trajectories following adolescent concussion. To investigate acute-to-subacute longitudinal changes in cortical thickness and subcortical volume following adolescent concussion, we compared neuroanatomical...

The plausible relationship between deep long-period earthquakes and volatiles: a case study of the Alaska-Aleutian arc

Abstract Deep long-period (DLP) earthquakes are observed beneath volcanoes in various tectonic settings during background activity, unrest, and eruption. The exact processes generating DLPs have been subject to ongoing debate, as they may provide insight into deep magmatic plumbi...

Decline or Renewal? The Carney Doctrine and the Prospects for Canadian Middlepowerism

This article examines whether the emergence of the Carney government represents a genuine renewal of Canadian middlepowerism or merely its latest reformulation amid continued structural decline. Tracing the erosion of Canada's post-war middle-power role across two decades of retr...

A protocol for biodiversity-informed wildlife disease surveillance

Land use and climate change are increasing the risk of spillover of zoonotic disease into human populations. However, we lack actionable information about the prevalence of pathogens in wildlife populations for most of the globe, challenging our ability to implement strategies to...

A new partial-equilibrium approach to approximating the welfare effects of market power and taxes

The traditional deadweight-loss (DWL) formula rests on a usually unstated, strong assumption: that all other markets are undistorted. We extend the DWL formula to cases where the surplus in other markets is non-zero. It involves an additional term of the same order of magnitude a...

Comparative Thermal Performance of 24 Lattice Topologies Under Low-Speed Mixed Convection Using Interface Heat Transfer Metrics

This study presents a computational comparison of 24 lattice topologies over their geometrically feasible relative density ranges. Conjugate heat transfer simulations were performed in ANSYS Fluent 2024 R2 using 10 mm unit cells, inlet air at 300 K and 0.05 m/s, a constant base t...

Sex-specific toxicological observations following 28-day oral gavage exposure to spherical and milled polystyrene nano- and microplastic particles in mice

Abstract Background With the rise in global plastic production, microplastics are an emerging environmental pollutant due to their ubiquitous presence in the environment. Human exposure and the impact of microplastics on human health warrants further research. Recent studies have...

De-escalation training across crisis-response sectors: a scoping review protocol

There is growing concern about violent or harmful encounters between crisis-intervention professionals and practitioners and individuals experiencing acute mental health crises, including those presenting with severe behavioural disturbances related to mental health concerns and/...

Beyond Disorder: Stigma and Identity Across the Substance Use Health Spectrum in a Public Health Framework

BACKGROUND: Despite the widespread prevalence and health impacts of substance use (including alcohol), policies and services remain anchored in diagnostic criteria, overlooking people whose substance use does not fit clinical categories. This structural emphasis on meeting diagno...

Matrix‐Activated Aptamer Sensors for Human Serum Analysis

ABSTRACT Owing to their ease of operation, solution‐phase fluorescent sensors hold a crucial position among aptamer‐based detection tools. However, their performance is regularly compromised when exposed to increasing levels of blood fluids, such as human serum, which limits thei...

Diverse microbial metal resistance and novel metal cycling organisms in copper/nickel mine tailings

Abstract Mine tailings contribute to environmental heavy metal contamination through the formation of acid mine drainage (AMD). Microbially-mediated processes such as iron and sulfur redox cycling influence metal mobility. Here, we applied an integrated metagenomic and metaproteo...
