Engineering SAN-core architecture in waterborne acrylic latexes for paper coating applications

Waterborne dispersion coatings are a potential alternative to extrusion coating and lamination for paper-based food packaging, but require latexes that combine barrier performance, film formation, and industrial processability. Here, poly(styrene- co -acrylonitrile) (SAN) was exp...

A multi-stage methodology for wind park inter-array cabling: graph preparation, routing, and sizing

Abstract. Inter-array grid optimisation plays a critical role in the technical and economic performance of wind parks and is typically divided into two primary tasks: layout length minimisation and conductor size selection. This work proposes the consideration of three primary ta...

A CXCR4-Targeted Dual-Acting Nanoconjugate Combines Protein-Toxin and Small-Molecule Warheads for Synergistic Cytotoxicity

Abstract Self-assembling multivalent protein nanoparticles with an architecture based on His-metal coordination and specific binding to cancer stem cells have emerged as promising tools for the selective delivery of microbial toxins in oncology, reaching precise cytotoxic effects...

Cosmological Constraints from Full-scale Clustering and Galaxy–Galaxy Lensing with DESI DR1

Abstract We present constraints on cosmic structure growth from the analysis of galaxy clustering and galaxy–galaxy lensing with galaxies from the Dark Energy Spectroscopic Instrument (DESI) Data Release 1. Our analysis includes four samples drawn from the Bright Galaxy Survey (B...

Optical properties and shape-dependent retrievals of the imaginary part of the refractive index of freshly emitted Saharan dust

Abstract. Mineral dust is a major contributor to atmospheric aerosols and plays a complex role in Earth’s radiation budget. However, large uncertainties remain in quantifying its direct radiative effects (DRE), primarily due to poorly constrained absorption properties. Most estim...

Cartographing Gravity: Operational Maps, the Conatus of Proper Time, and the Potentia of Matter

Classical natural philosophy sought the natural law governing the motion of free bodies long before daring to construct the appropriate mathematical formalism. Following this longstanding methodological perspective, in the present work General Relativity is reconstructed from ope...

Joint Modeling of GD-1 and C-19 as Old Streams

Abstract DESI observational data for the GD-1 and C-19 streams are compared to stream simulations in an evolving multihalo potential of a Milky Way–like galaxy based on a cosmological Milky Way–like simulation. The number of subhalos decreases with time, and the subhalo-stream en...

The emancipation of technology as a subject: teachers’ views of technology content in secondary education

Abstract The roles of technology and engineering within STEM education have evolved from a focus on technology as a product to a broader vision encompassing the processes involved in its creation, closely linked to engineering. As the newest disciplines in STEM education, technol...

Characterizing lightning NO x production in the Ebro Valley with meteosat 12 LI and LMA observations

Abstract. Lightning is one of the main sources of NOₓ in the Earth’s atmosphere, yet there is considerable variability in NOₓ production during thunderstorms. In this study, we combined optical lightning data from the Meteosat Third Generation (MTG) Lightning Imaging (LI) instrum...

Seeing through others’ eyes in immersive VR: insights from a user study

Abstract Despite the increasing usage of collaborative Virtual Reality in classrooms, teachers often struggle to ascertain whether the participants are adequately sharing the same viewpoint and are seeing the same information during lectures. Virtual Reality offers numerous advan...

Image of the City in the Age of Large Language Models: ChatGPT as a New Urban Observer

This research examines how city images of Istanbul’s Historic Peninsula are evolving with artificial intelligence and expanding user-generated content. City image refers to a mental representation of urban structure, and imageability to the ease of forming it. Using Lynch’s five-...

Secure estimation in fuel cells: Eavesdropping prevention and attack detection performance

This work presents a nonlinear masking signal protocol to privatize data against eavesdropping attacks in a nonlinear remote estimation problem. The protocol is based on the addition of a masking signal at the source node and a removal filter at the end node. The stability and ro...

Adaptive Reuse Strategies in European Christian Churches

In Europe, Christian churches constitute a substantial part of listed heritage. These numerous liturgical spaces are highly significant to the image of cities and possess unquestionable spatial, material, environmental, and symbolic qualities, yet paradoxically society has progre...

The Composite Spectrum of QSO Absorption Line Systems in DESI DR2

Abstract We present details regarding a composite spectrum of quasar (QSO) absorption line systems. In this composite spectrum, we identify more than 70 absorption lines and observe oxygen and hydrogen emission features at a higher signal-to-noise ratio than any previous study. A...

Advanced Textiles, Sustainability, and Digital Transformation in Textile Research

Throughout 2025, Textiles published a broad array of original research articles and reviews that demonstrate the rapid technological evolution of textile science and technology [...]

The DESI Y1 RR Lyrae Catalog. II. The Metallicity Dependency of Pulsational Properties, the Shape of the RR Lyrae Instability Strip, and Metal Rich RR Lyrae

Abstract RR Lyrae stars (RRLs) are valuable probes of both Milky Way assembly and stellar-evolution physics. Using a sample 6240 RRLs obtained in the first year of the Dark Energy Spectroscopic Instrument (DESI) survey, we investigate the metallicity of RRLs and its correlation w...

The DESI Y1 RR Lyrae Catalog. I. Empirical Modeling of the Cyclic Variation of Spectroscopic Properties and a Chemodynamical Analysis of the Outer Halo

Abstract We present the catalog of RR Lyrae stars (RRLs) observed in the first year of operations of the Dark Energy Spectroscopic Instrument (DESI) survey. This catalog contains 6240 RRLs out to ∼120 kpc from the Galactic center and over 12,000 individual epochs with homogeneous...

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...

Evaluation of a cathelicidin derivative fusion polypeptide for pathogen-targeted antimicrobial approach

Abstract The human cathelicidin LL-37 is one of the most promising candidates for replacing standard antibiotics due to its broad-spectrum activity and low propensity for resistance development. However, the widespread clinical adoption of antimicrobial peptides (AMPs) is current...

Analysis of Tonga eruption-induced disturbances in the upper thermosphere based on atmospheric drag accelerations from LEO satellites

Abstract The violent eruption of the Tonga volcano on 15 January 2022 triggered significant disturbances in the atmosphere and ionosphere. However, limited observational capabilities have persistently hindered the characterization of eruption-induced neutral density disturbances...
