Percolation transition of K -destinations reveals universal backbone of urban mobility networks

Abstract Cities are held together by a small subset of recurrent origin–destination ties, but extracting this backbone from noisy mobility data remains difficult, and most models still prioritize distance over connectivity. We build directed mobility networks from 48 months of mo...

Analyzing night illumination in dependency of cloud coverage and altitude

Abstract Despite the publication of a large number of scientific studies in recent years, the impact of clouds on night illumination remains inconclusive. It is also unclear how clouds affect the ever-increasing prevalence of artificial lighting and the subsequent brightening of...

Extracellular vesicles for next-gen therapeutics and drug delivery

Extracellular vesicles (EVs) are membrane-bound, nano-sized particles released by diverse cell types. They serve as key mediators of intercellular communication by transporting a broad repertoire of proteins, lipids, nucleic acids, and metabolites to recipient cells within a prot...

Indicator Compliance in Bulk Water Does Not Reflect Biofilm-Associated Microbial Community Composition or Potential Risk in UV-C LED-Treated Rainwater Harvesting Systems

Abstract Rainwater harvesting (RWH) systems are increasingly used to supplement potable and nonpotable water supplies but remain understudied with respect to biofilm-associated microbial risk. This study used a pilot-scale, temperature-controlled pipe loop to investigate how pipe...

Three decades of microcystin-LR removal in aquatic environments: physical, chemical and biological strategies for environmental detoxification

Abstract Microcystin-LR (MC-LR) contamination from cyanobacterial blooms poses a persistent threat to aquatic ecosystems and human health, necessitating effective removal technologies. This study used visualization analyses to examine global research on MC-LR removal in aquatic e...

Geometric Bounds on Metric Communication Channels in Static Spherically Symmetric Spacetimes

We examine a restricted family of static, spherically symmetric zero-redshift geometries that act as localized radial deformations of the flat radial metric. The motivation is simple: for radial null curves between two fixed areal-radius spheres, the same coefficient that changes...

Thermodynamic Geometry of Alpha Statistics: A Unified Quantum Statistical Framework

We propose and study a generalized quantum statistical framework–referred to as alpha statistics–that continuously interpolates between Bose–Einstein and Fermi–Dirac statistics and naturally extends into the hyperbosonic regime for [Formula: see text]. Inspired by Haldane’s exclu...

Anthropogenic modification shifts pollinator phenology in the eastern USA

Abstract Understanding the effects of increasing anthropogenic changes on ecological communities is integral to predicting and mitigating such changes in the future. Insect pollinators are vital to ecosystem health. Quantifying pollinator phenology (i.e. flight period) offers ins...

A Manganese-Chlorella Hydrogel for an Integrated “Remove–Remodel–Repair” Strategy in Pancreatic Cancer Therapy

Abstract Pancreatic cancer faces the challenges of tumor progression and postoperative pancreatic fistula during the perioperative period, which severely affect patient prognosis. In this study, an injectable self-healing multifunctional hydrogel (CMCGel) was developed based on d...

Hierarchical Electronic Transport in Giant Mixed-Valence {Mo154} Rings Revealed in Anhydrous Single-Molecule-Layer Networks

Abstract Polyoxometalates (POMs) are redox-active metal–oxo clusters of central interest in molecular and materials chemistry. The giant mixed-valence {Mo154} ring, built from 14 repeating subunits, is a prototypical system expected to exhibit rich electronic functionality; howev...

Artificial Intelligence for Endoscopic Diagnosis of Gastric Premalignant Lesions

Gastric cancer is a leading cause of cancer-related mortality worldwide. The Correa cascade posits that intestinal-type gastric adenocarcinoma develops through a stepwise progression from chronic gastritis to atrophic gastritis, intestinal metaplasia, and dysplasia, highlighting...

Baryon number density dependent charged compact star admixed with dark energy: consistent with recent observational results

In this work, we investigate an anisotropic charged compact star model interpreted as a strange quark star in [Formula: see text]-equilibrium admixed with dark energy. The effects of finite strange quark mass ([Formula: see text]) and baryon number density ([Formula: see text]) a...

Helicity conservation of the Riemann–Silberstein vector

Abstract In this paper, we consider Riemann–Silberstein (RS) helicity (RSH) given by the sum of the electric and magnetic helicities. We show that this quantity is chiral under parity transformation and invariant under duality. In the case of null fields in free space, we prove t...

Using computer games to explore foraging-predation trade-offs and spatial learning in humans

Abstract Foraging requires organisms to balance energetic gains against multiple costs, including predation risk, while updating decisions as conditions change. Although these processes are well studied in animals, ecologically grounded paradigms for testing behavioural updating...

Theoretical foundations of soft topological granular structures for multi-criteria social network analysis

Abstract Granular computing (GrC) models complex systems through hierarchically organized information granules, whereas soft set theory offers a flexible mathematical framework for parameter-dependent uncertainty. Motivated by their strong conceptual affinity, this paper develops...

Timing of aneurysm repair and clinical outcomes after aneurysmal subarachnoid hemorrhage: a systematic review

BACKGROUND: Aneurysmal subarachnoid hemorrhage (aSAH) causes substantial morbidity and mortality, and guidelines recommend aneurysm repair as early as feasible. However, the association between onset-to-treatment time and outcomes remains uncertain. This review synthesized eviden...

Silicon-Based Polyurea Composite Coatings with a Hydrogen Bond-Enhanced Network for Improved Mechanical Strength, Transparency, and Solvent Resistance

Abstract Polyurea materials have attracted considerable attention in fields such as protective coatings and elastomers due to their unique microphase-separated structure and dynamic hydrogen-bonding network. However, achieving high mechanical strength, excellent optical transpare...

Validation and optimization of a multi-processor UV-C reactor for inactivation of potato brown rot and soft rot pathogens in surface irrigation water in the Nile Delta

Abstract Bacterial wilt and soft rot, caused by Ralstonia solanacearum and Pectobacterium carotovorum , are major threats to potato production and export. Surface irrigation water (SIW) can transmit these pathogens. This study validated and optimized a multi-processor UV-C (MP UV...

Local Strong-Field Properties of Anisotropic Traversable Wormholes in dRGT- f ( R , T ) Massive Gravity

We investigate local strong-field properties of anisotropic traversable wormholes in dRGT-f(R, T) massive gravity. We identify the physically admissible anisotropic branch and show that the isotropic branch fails the Morris–Thorne traversability conditions. Since the resulting ge...

Titanosaur eggshells from the latest Cretaceous of Patagonia, Argentina: implications for nesting at high latitude

Abstract Dinosaur egg remains are rarely found in areas of high palaeolatitudes, with Canada (approx. 57–60° N) and Siberia (approx. 70–75° N) yielding the most polarward occurrences. Here, we describe dinosaur eggshells from the Upper Cretaceous (Maastrichtian) Chorrillo Formati...
