Optimal Parallel Comparison Sorting for Up to 10 Elements on Up to 10 Processors

We study the problem of parallel comparison sorting, modeled as a two-player game between a sorter and an adversary. Using a minimax algorithm enhanced with several domain-specific optimizations, we compute the exact minimal number of rounds [Formula: see text] required to sort [...

Thinking with Objects. Understanding Non-Representational Cognitive Artifacts

This paper defends the notion of cognitive artifacts that do not serve representational functions. Contrary to the standard account of cognitive artifacts as representational, we argue that it is possible to distinguish a special class of artifacts that fulfill cognitive roles wi...

Inflammation induced by endotoxin from Escherichia coli enables the central action of caffeine on GnRH/LH secretion in female sheep

Caffeine is considered to be the most utilized psychoactive stimulant worldwide. It easily crosses the blood-brain barrier and may antagonize adenosine receptors and activate ryanodine receptors in the brain. Administered peripherally, caffeine reduces inflammatory-associated cha...

Microstructure-driven formation of a chemically graded corrosion layer in PBF-LB/M fabricated dual-phase Mg–8Li–0.5Ca wt.% ultralight alloy

In this study, a dual-phase Mg-8Li-0.5Ca wt.% ultralight alloy was successfully fabricated using powder bed fusion - laser beam/metals (PBF-LB/M). The as-built microstructure consisted of α(Mg) enriched with microscale Mg-Ca precipitates and β(Li) containing nanosized needle-like...

The Weak Banach–Saks Property for Hölder Spaces

ABSTRACT We investigate the weak Banach–Saks property in the setting of Hölder spaces over metric spaces. We show that, for every infinite metric space and every , the Hölder space fails to have the weak Banach–Saks property.

Radiological characteristics of coal-to-ash transformation: a paired coal-ash assessment of natural radionuclides

Abstract Naturally occurring radioactive materials (NORM) in coal and its combustion residues represent a potential source of environmental contamination, particularly under large-scale energy production and waste reuse scenarios. However, the radiological transformation of radio...

From generic to salutogenic urbanism: Evidence of the landmark paradox and the role of biodiversity and walkability in mental health

Public place walkability is central to health-oriented urban planning. Facing a global polycrisis (climate, mental health, physical activity, and biodiversity challenges) salutogenic environmental research is crucial for cross-sector recommendations. Yet, evidence integrating psy...

A multimodal model of aqueous humor small RNA and clinical features shows limited discrimination between primary open-angle and pseudoexfoliative glaucoma

Abstract Glaucoma is a leading cause of irreversible blindness worldwide and encompasses diseases with different clinical presentations, including primary open-angle glaucoma (POAG) and pseudoexfoliative glaucoma (PXG). We investigated whether smallRNA profiles in aqueous humor,...

Shaping the future of transit: Innovations and prospects of intelligent connected bus systems

Abstract As urbanization progresses, traffic congestion has become an increasingly severe issue confronting metropolitan areas worldwide. Intelligent connected bus systems (ICBS) emerge as a transformative solution to address this challenge. This review synthesizes ICBS as a laye...

Alon–Tarsi for Hypergraphs

Given a hypergraph $H=(V, E)$, define for every edge $e\in E$ a linear expression with arguments corresponding to the vertices. Next, let the polynomial $p_H$ be the product of such linear expressions for all edges. Our main goal is to find a relationship between the Alon-Tarsi n...

Comparison of the Performance of Various Volterra Filters Used for the Equalization of the Channel Dynamic Nonlinearity

In this work, the performance of Volterra filters of various orders (both standard and modified) in compensating for dynamic nonlinear distortions arising during digital transmission was investigated through simulation. A binary signal was employed, and the nonlinear dynamic elem...

Application of mobile mapping technology in automating inventory and legal compliance checks for advertising signs and devices

Abstract The increasing number of advertisements in public spaces, combined with ineffective control mechanisms, leads to growing visual pollution in urban areas. The aim of this study was to develop and evaluate a semi-automated workflow for the inventory and legal compliance as...

Construction and characterisation of the DarkSide-20k veto silicon photo-multiplier tiles

Abstract Silicon photo-multipliers (SiPMs) are state-of-the-art sensors capable of detecting a single photoelectron under cryogenic conditions, with potentially lower radioactivity than widely used photomultiplier tubes. The DarkSide-20k experiment, designed to perform direct dar...

Two-Pass Friction Stir Welding of AZ31/AA1050 Bimetallic Butt–Lap Joint

Abstract This study evaluated the feasibility of friction stir welding (FSW) of AZ31/AA1050 bimetallic plates produced by explosive welding. The investigated material had a total thickness of 10 mm (5 + 5 mm) and, after milling, 8 mm (4 + 4 mm). Butt–Lap joints were produced usin...

Max Weight Independent Set in sparse graphs with no long claws

For graphs \(G\) and \(H\) , we say that \(G\) is \(H\) -free if it does not contain \(H\) as an induced subgraph. Already in the early 1980s Alekseev observed that the Max Weight Independent Set problem ( MWIS ) remains NP -hard in \(H\) -free graphs, unless every component of \...

Gigavoxel-scale multiple-scattering-aware lensless holotomography

Abstract Holotomography (HT) has revolutionized quantitative label-free 3D imaging, yet conventional lens-based implementations are fundamentally constrained in field-of-view (FOV) and imaging depth, limiting their utility for critical high-throughput applications in material and...

The Role of the Main Motion Drags in Middle-Class Passenger Car Drive System Development

The article analyses the significance of the four main resistances (drags) existing during the straight-line motion of a car, arising from rolling, longitudinal aerodynamics, road longitudinal inclination (grade), and inertia of the body and rotating parts. Their shares in the to...

dcHiChIP: A comprehensive Nextflow-based pipeline for multiscale analysis of chromatin architecture from HiChIP data

Abstract Motivation Despite the growing use of HiChIP to investigate protein-directed chromatin architecture, a comprehensive and reproducible pipeline for analyzing these datasets-from raw reads to multiscale 3D genome features-remains lacking. Existing tools often focus on isol...

Evanescent Absorption Spectroscopy of Transition Metal Dichalcogenide Materials Using Guided Photoluminescence in Si3N4 Photonic Waveguides

Abstract On-chip integration of two-dimensional transition metal dichalcogenides (TMDs) with photonic waveguides underpins a growing class of compact optoelectronic and sensing devices, whose performance depends on the optical absorption of the two-dimensional (2D) material in th...
