Enriched experience increases reciprocal synaptic connectivity and coding sparsity in higher-order cortex

The integration of new information during sleep reshapes cortical representations that support categorical knowledge. Auto-associative attractor network theories predict that reciprocal excitatory connections help form stable categorical attractors, but direct evidence is missing...

Fractional angular momentum and quasi-probability densities for angular degrees of freedom

In the present study, we consider quasi-probability densities W[θ, p] and W1/2[θ, p] for pure states depending on two classical parameters θ and p, where −π ≤ θ ≤ π and p can take any real number. For integer values of p, the corresponding marginal distributions W[p] and W1/2[p]...

A state-of-the-art review on crew competence in maritime and nuclear remote operations

The global maritime shipping sector accounts for approximately 3% of global greenhouse gas (GHG) emissions. In response to climate concerns, the maritime industry is increasingly pursuing technological solutions to reduce emissions. This study is part of the Nuclear Propulsion fo...

Insights into interaction management through backchannels

Abstract This paper analyzes backchannel signals in two signed languages: French Belgian Sign Language (LSFB) and Catalan Sign Language (LSC). While backchannels have been extensively studied in spoken languages, their documentation across signed languages remains sparse in compa...

Tertiary-care management of TB/HIV co-infection in Port Harcourt, Nigeria: A retrospective cohort analysis

ABSTRACT Background Monitoring the treatment of tuberculosis(TB) and human immunodeficiency virus(HIV) co-infection is very important to improve patient management and compliance. This study assessed the treatment outcomes of registered TB/HIV co-infected patients enrolled in the...

Learning environment perceptions among occupational therapy students in Norway: sociodemographic, study behaviors, and performance covariates to cluster allocation

Little is known about how learning environment (LE) perceptions cluster within student populations and how such profiles relate to study behaviors and performance. This study aimed to identify clusters of Norwegian occupational therapy students based on their LE perceptions and t...

What Really Drives People-first Public-private Partnerships Adoption? Evidence From Resource-constrained Settings

Abstract This study examines the factors influencing the adoption of People-First Evaluation Methodology (PFEM) in Public-Private Partnerships (PPPs) operating within resource-constrained contexts. Using Partial Least Squares Structural Equation Modeling applied to survey data, t...

On Goldbach numbers in short intervals

Assuming the Riemann Hypothesis, we prove that for all $$x\geqslant 2$$ , there exists at least one even integer within the interval $$(x, x+123\log ^2x]$$ , that can be expressed as the sum of two primes. This result is an improvement over the recent work of Cully-Hugill and Dud...

Delivering building demand flexibility for grid-interactive operation: from perception and cognition to decision, execution, and verification

As both buildings and power systems undergo rapid decarbonization, demand flexibility (DF) in buildings has emerged as a key enabler for renewable energy integration, grid reliability, energy resilience, and efficient and low carbon operation. By dynamically adjusting building en...

Molecular Structure–TribologicalPerformanceRelationship in Tungsten-Based Polyoxometalate Ionic Liquid LubricantAdditives

Abstract Polyoxometalate ionic liquids (POM-ILs) represent a class of multifunctional materials combining the structural tunability of polyoxometalates (POMs) with the versatile properties of ionic liquids (ILs). In this work, a series of POM-ILs were designed, synthesized, and e...

Distribution of device-measured 24-hour movement behaviours across the cognitive spectrum in older adults: the HUNT study

Abstract Background Key daily physical activities (e.g., standing and walking), postures (sitting and lying), and sleep constitute the 24-h day and have distinct health effects and functional implications. Traditionally studied separately, the distribution of these movement behav...

Genetic clusters of BMI reveal symptom-specific causal effects on depression

Abstract While BMI is phenotypically and genetically associated with depression, the extent to which BMI causes depression and the mechanisms underlying this effect remain unclear. We estimated the causal effect of BMI on depression symptoms, accounting for complexity in both the...

Fatigue after ischaemic stroke: A five-year longitudinal study of prevalence and latent trajectory subgroups

Objective To investigate the prevalence and longitudinal course of post-stroke fatigue and identify subgroups with distinct fatigue trajectories up to 5 years post-stroke. Design A prospective, longitudinal, multi-centre cohort study. Setting Hospital stroke units in the Central-...

Production, Biodegradation,and Recalcitrance of OrganicCarbon from Cultivated Saccharina latissima in Norway

Abstract Particulate (POC) and dissolved (DOC) organic carbon released during macroalgae cultivation has been shown to lead to carbon burial and export to the open ocean and deep sea. The recalcitrant portion of the DOC (RDOC) is a critical contributor to carbon sequestration and...

Time-resolved imaging of antiferromagnetic skyrmion interactions

Abstract Quantifying particle interactions is central to understanding and controlling collective dynamics in particle-based devices such as those comprising skyrmion ensembles. Here we directly visualize, in real time, the nanosecond current-driven dynamics of an antiferromagnet...

7 Tesla MRI with Quantitative Susceptibility Mapping: qualitative grading and quantitative focal measurements of the substantia nigra as a potential biomarker for Parkinson’s disease

PURPOSE: Parkinson's disease (PD) is characterized by dopaminergic neuronal loss in the substantia nigra (SN). Imaging biomarkers sensitive to nigral pathology are limited. This study evaluated susceptibility changes in the SN using quantitative susceptibility mapping (QSM) and s...

Fabrication and performance evaluation of TiO2 nanoparticle modified cellulose/PBS biocomposites

Abstract In this study, jute fiber cellulose (JFC) was extracted from raw jute fibers using an alkaline (NaOH + H 2 O 2 ) chemical treatment. Titanium dioxide (TiO 2 ) nanoparticle-dispersed cellulosic biocomposite films (JFC-TiO 2 ) were subsequently fabricated and coated with b...

Tuning electron back-donation to switch reaction pathway in CO2 hydrogenation

CO2 hydrogenation over earth-abundant Ni catalysts is attractive for CO-based fuel synthesis, but Ni intrinsically favors methanation. Here we show that ordered Ni3Sn2 intermetallics tune Ni–CO electron back-donation and switch CO2 hydrogenation from CH4 formation to the reverse...

Extinction Prediction and Emission Analysis of a Bluff-Body Stabilized Ammonia-Hydrogen-Nitrogen Premixed Flame With Conjugate Heat Transfer

Abstract Ammonia/hydrogen blends represent a promising carbon-free fuel for gas turbine combustors. To minimize the NOx emission, premixed ammonia/hydrogen/nitrogen flames under ultra lean equivalence ratios are investigated. This paper simulates the extinction process of a bluff...

Effects of maternal and paternal smoking on offspring cardiometabolic risk factors in adulthood: a multi-method intergenerational Mendelian randomization study

Abstract Background Parental smoking has been linked to several adverse offspring cardiometabolic outcomes; however, evidence is conflicting regarding the causal and long-term nature of these associations. Methods We investigated the effects of maternal and paternal smoking, capt...
