Perceptions of (In)Security in Portuguese Schools: A Multidimensional Approach to Safety and Youth Development

Introduction: School safety plays a crucial role in fostering a healthy learning envi-ronment and supporting Positive Youth Development (PYD), encompassing physical, emotional, and social dimensions of well-being. This study aimed to explore and char-acterize the perception of sa...

Bacterial ribonucleoprotein bodies maintain an acidic pH environment as a mechanism of enzyme regulation

Abstract Phase separated biomolecular condensates create subcellular niches, yet their role in client regulation remains unclear. Here, we demonstrate that Bacterial Ribonucleoprotein bodies (BR-bodies) are acidic. Using ratiometric fluorescent probes in vivo , we find BR-bodies...

Synergistic antitumor immune activation in melanoma using LA-PegPI polymeric gene vaccine in conjunction with PD-1 inhibition

Cancer gene vaccines are a promising avenue for cancer immunotherapy; however, their success depends not only on the gene construct itself but more critically on the efficacy and safety of the gene delivery vehicle. Targeting dendritic cells (DCs), the specialized antigen-present...

Investigating regional electricity consumption across Europe: a spatial analysis

Electricity is increasingly central to Europe's energy transition, but evidence on regional consumption remains limited by the lack of harmonised sub-national data. We address this gap by constructing a regional electricity consumption dataset covering all EU Member States and se...

Evaluation of Pulmonary and Otological Manifestations in Primary Ciliary Dyskinesia and Their Effect on Quality of Life

ABSTRACT Objective Otitis media and conductive hearing loss are common in patients with primary ciliary dyskinesia (PCD). We primarily aimed to assess the impact of otologic features of individuals with PCD on health‐related quality of life (QOL), and our secondary aims are chara...

Mentalizing and heuristics as distinct cognitive strategies in human teaching

Teaching is a foundational social behaviour that can result from mentally effortful reasoning or cognitively frugal heuristics. When do people use these strategies to teach? Here we investigated this using behavioural experiments and computational modelling with adult participant...

Effects of aerobic, resistance, and combined exercise training on coagulation and fibrinolytic activity in major burns: a preliminary randomized trial

Abstract Background This study aimed to compare the effects of different exercise protocols—resistance, aerobic, and combined resistance-aerobic training—on coagulation and fibrinolytic activity in major burns. Methods This prospective, randomized study included 30 major burn pat...

Topological dimension of the Gromov–Hausdorff and Gromov–Prokhorov spaces

The Gromov–Hausdorff distance is a dissimilarity metric capturing how far two spaces are from being isometric. The Gromov–Prokhorov distance is a similar notion for metric measure spaces. In this paper, we study the topological dimension of subspaces of the Gromov–Hausdorff and G...

Improved quasi-invariance result for the periodic Benjamin–Ono–BBM equation

Abstract We extend recent results of Genovese–Luca–Tzvetkov (2022) regarding the quasi-invariance of Gaussian measures under the flow of the periodic Benjamin–Ono–BBM (BO-BBM) equation to the full range where BO-BBM is globally well-posed. The main difficulty is due to the critic...

Unveiling the nexus between products and influential countries in the multi-layer trade network of global lithium battery

Amid the accelerating global transition to renewable energy and the surge in electric vehicle adoption, ensuring the stability of the lithium battery supply chain has become a critical priority. This study explores the complex relationships between products and influential countr...

Functional Structural Equation Modeling with Latent Variables

Handling latent variables in Structural Equation Models (SEMs) where both the latent variables and their corresponding indicators are random curves presents significant challenges, especially with sparse data. We develop a novel family of Functional Structural Equation Models (FS...

Enhancing operational wind downscaling capabilities over Canada: Application of a Conditional Wasserstein GAN methodology

Abstract Downscaling based on Artificial Intelligence (AI) has been demonstrated to be a powerful tool for improving the spatial resolution of weather forecasts. This study advances wind downscaling by extending the DownGAN framework introduced by Annau et al. to operational Cana...

The Impact of Monetary Policy Shocks on Stock Price Crash Risk

ABSTRACT This study examines the impact of monetary policy shocks (MPS) on future stock price crash risk (SPCR), using a sample of US firms from 1995 to 2019. We find that expansionary MPS significantly reduce the likelihood of SPCR, while contractionary MPS show no statistically...

Positivstellensatz for C*-tensor categories

We explore semi-pre-C*-algebras in the context of rigid semisimple C*-tensor categories and using techniques from annular representations, we extend Ozawa’s criterion for property (T) in groups to this context.

Decoupling multistep schemes for elliptic–parabolic problems

We study the construction and convergence of decoupling multistep schemes of higher order using the backward differentiation formulae for an elliptic–parabolic problem, which includes multiple-network poroelasticity as a special case. These schemes were first introduced in [Altma...

Study on dynamic load stress transfer hindered by air/water medium fractures

Abstract Hydraulic fracturing technology leads to the development of lots of fractures in the surrounding rock reservoir, forming a three-dimensional fracture network, which plays a role in hindering the transfer of high stress. Under temporal-spatial influence, however, the frac...

Economic and Environmental Implications of Ride-Hailing and Vehicle Age Limits for Car Sales Markets

Problem definition: Ride-hailing poses significant challenges to Original Equipment Manufacturers (OEMs) as it offers an affordable mobility option, and thus may lead to lower new car ownership. Yet, its more intense competition with the sales of used cars in secondary markets (a...

Boundedness of Composition Operators in Orlicz–Morrey Spaces

ABSTRACT In this paper, we investigate the necessary and sufficient conditions for the boundedness of composition operators on Orlicz–Morrey spaces. Our results encompass Lebesgue and generalized Morrey spaces as special cases. In addition, we characterize the boundedness of comp...

Community: Component based differential cell communication analysis in large multi-sample case-control scRNAseq datasets

Abstract Cell-cell communication is essential for physiological tissue function. In disease, communication often gets disbalanced by changes in the tissue cell type composition, fraction of cells engaged in communication, and changes in expression levels of ligands, receptors and...

Service Systems with On-Demand and Reserved Servers

Problem definition: In many real-world applications, such as cloud computing, there is a growing trend to supplement long-term reserved capacity with short-term on-demand capacity. We study a queueing system that employs both reserved and (relatively more expensive) on-demand ser...
