Abstract Introduction Substance Use Disorders (SUDs) pose significant public health challenges in sub-Saharan Africa. However, there is limited evidence on how service users (SUs) and front-line health care workers (HCWs) experience SUD treatment and recovery within resource cons...

A New Scale of Function Spaces Characterizing Homogeneous Besov Spaces
Abstract We introduce and study a new scale of function spaces that characterize the homogeneous Besov spaces $$\dot{\text {B}}^{\beta }_{p,q}$$ B ˙ p , q β , hence completing earlier work by Ullrich. These new spaces include the ones introduced by Barton and Mayboroda, and syste...

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]...

Background: Structural brain changes during the earliest asymptomatic stages of Alzheimer's disease (AD) remain poorly understood. Previous research in preclinical AD shows heterogeneous findings, reporting both subtle neuronal loss and paradoxical increases in grey matter (GM) v...

The Recognition and Vulnerability of Olympic Sports: The Case of Basque Pelota (1900–1992)
The path to Olympic recognition remains challenging for many disciplines. While some sports successfully navigate this road, traditional and regional sports face significant barriers. Basque pelota exemplifies these difficulties. Its case highlights the challenges a sport can fac...

We present a novel scheme for hybrid integration of quantum cascade laser bars with germanium-on-silicon waveguides operating in the mid-infrared. The laser bars are flip-chip bonded onto a germanium-on-silicon target chip without active alignment, acheiving end-fire coupling eff...

Abstract Mutation specific therapeutic approaches, like exon skipping or gene-editing, hold promise for the treatment of Duchenne muscular dystrophy (DMD). Translatability of preclinical studies investigating these approaches could greatly be improved through the use of humanized...

Background: There is currently limited information about sensory and perceptual abilities across the progression of CLN3 disease (Juvenile Neuronal Ceroid Lipofuscinosis; Batten disease), a recessively inherited lysosomal storage disorder and a leading cause of childhood neurodeg...

Non-Abelian Amplification and Bilinear Forms with Kloosterman Sums
Abstract We introduce a new method to bound bilinear (Type II) sums of Kloosterman sums with composite moduli $c$ c , using Fourier analysis on $\mathrm{SL}_{2}(\mathbb{Z}/c\mathbb{Z})$ SL 2 ( Z / c Z ) and an amplification argument with non-abelian characters. For sums of length...

Over 50% of Thailand's floating population is located inside the Bangkok Metropolitan Region (BMR). Its growth presents a significant challenge to public budget planning due to the uncertainty associated with individuals residing outside civil registration vital statistics (CRVS)...

In the face of ever-accelerating climate change and ecological degradation, the concept of sufficiency has been proposed as a way to achieve socio-ecological sustainability. Sufficiency implies limits on consumption and production, thus making it incompatible with capitalism’s no...

Multiperiod Mean-Buffered Probability of Exceedance in Defined Contribution Portfolio Optimization
Abstract. We investigate multiperiod mean–risk portfolio optimization for long-horizon Defined Contribution plans, focusing on buffered Probability of Exceedance (bPoE), a more intuitive, dollar-based alternative to Conditional Value-at-Risk (CVaR). We formulate both precommitmen...

A Tight SDP Relaxation for the Cubic-Quartic Regularization Problem
Abstract This paper studies how to compute global minimizers of the cubic-quartic regularization (CQR) problem $$ \min _{s \in \mathbb {R}^n} \quad f_0+g^Ts+\frac{1}{2}s^THs+\frac{\beta }{6}\Vert s \Vert ^3+ \frac{\sigma }{4} \Vert s\Vert ^4, $$ min s ∈ R n f 0 + g T s + 1 2 s T...

Tau self-assembly and intracellular deposition is associated with a group of neurodegenerative diseases called tauopathies, which include Alzheimer's disease (AD) and Pick's disease. Here, we measured the proteome response in human neuronal cells (differentiated SH-SY5Y) followin...

Abstract Conventional suture anchor methods in rotator cuff repair often fail to replicate the native tendon-to-bone interface, leading to re-tears due to stress concentrations and poor biological integration at anchor sites. To address these challenges, we engineered a biomimeti...

Abstract Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine–metabolic disorder commonly associated with insulin resistance and early cardiovascular dysfunction. Soluble CD40 ligand (sCD40L) and soluble E-selectin (sE-selectin) are circulating markers reflecting immune...

Policy options for strengthening health technology assessment in Iran
Abstract Since health technology-related issues pose ongoing challenges for health systems, ensuring proper Health Technology Assessment (HTA) and its efficient and effective use for health care is essential. After more than a decade since the start of this system in the Iranian...

Aging Alters Hair Cell Physiological Properties in Mice With Late‐Onset Age‐Related Hearing Loss
ABSTRACT Mammalian cochlear hair cells convert acoustic stimuli into electrical signals, which are relayed to the central auditory pathway via auditory neurons. Progressive loss of hair cells and their synapses is a characteristic of age‐related hearing loss (ARHL), but the under...

Metabolic plasticity supports a flexible nutritional symbiosis in Cardiocondyla ants
Abstract Nutritional symbioses have repeatedly evolved in insects, yet how hosts regulate these partnerships to balance benefits across development and environments remains unclear. Ants provide an exceptional system to address this question, as several lineages maintain ancient...

Isolation of non-triangle cycles in graphs
Given a set $\mathcal{F}$ of graphs, we call a copy of a graph in $\mathcal{F}$ an $\mathcal{F}$-graph. The $\mathcal{F}$-isolation number of a graph $G$, denoted by $ι(G, \mathcal{F})$, is the size of a smallest set $D$ of vertices of $G$ such that the closed neighbourhood of $D...
