Mixed volumes of zonoids and the absolute value of the Grassmannian

Abstract Zonoids are Hausdorff limits of zonotopes, while zonotopes are convex polytopes defined as the Minkowski sums of finitely many segments. We present a combinatorial framework that links the study of mixed volumes of zonoids (a topic that has applications in algebraic comb...

Metal Magnetic Memory-Based Electromagnetic Non-Destructive Evaluation of Steel-Core Damage in UHV ACSR Conductors

Internal steel-core damage hidden within aluminum conductor steel-reinforced (ACSR) compression components may threaten the mechanical integrity of ultra-high-voltage transmission lines. This laboratory study evaluates metal magnetic memory testing (MMMT) responses to artificial...

A Multi-Strategy Kangaroo Escape Optimization Technique for Global Optimization, Engineering Design, and Near-Infrared Prediction of Praeruptorin Content

The Kangaroo Escape Optimization Technique (KET) combines escape and safe-area searches, but its fixed stage allocation, restricted guidance range, limited refinement of low-ranked individuals, and insufficient use of population-state information can reduce its performance on com...

Perceptions of turnout gear fit and movement restrictions among firefighters of different gender, service type, and measurement status

To understand the factors contributing to ill-fitting gear, this study investigated user perceptions across firefighters of different gender, service type, and pre-sizing measurement status. A total of 345 firefighters (19.8% women, 34.8% volunteer firefighters, and 18.0% not mea...

Fish Assemblages Distinguish Eco-Friendly from Conventional Rice Paddies Through Abundance and Biomass Rather than Diversity

Although rice paddies are agricultural land, they also serve as artificial wetlands that deliver essential ecosystem services. Yet how farming systems affect their fish communities—and which metrics best capture those effects—remains poorly quantified in Asia. We compared fish as...

Reproductive and endocrine responses to short-term safflower seed supplementation in anestrous ewes synchronized with progestagen

Abstract. This study investigated the effects of short-term supplementation with safflower seed, a linoleic-acid-rich oilseed, on reproductive performance and endocrine responses in Hungarian Merino ewes during the non-breeding season. Forty-four clinically healthy multiparous ew...

Phi-Driven Irrational Scaling in 5-Fold Quasicrystals — E8 Intelligence Research

The E8 root system's phi-coupling (φ = (1+√5)/2) embedded in its 240 root vectors enables geometric derivation of ψ = √(2φ), a new irrational scaling factor bridging Sulba Sutras' √2 approximation and Penrose tilings' 5-fold symmetry. This ψ factor, synchronized with 132Hz base f...

Neuromuscular Activation Strategies of the Lower Limb During Maximal Sprinting in Youth Track and Field Athletes: Age-Related Differences and Implications for Talent Identification

Sprint performance improves throughout adolescence as a result of both structural and neuromuscular development. In particular, increases in body height, lower limb length, and muscle volume have been consistently linked to improvements in sprint performance. However, allometric...

Impact of preoperative venovenous extracorporeal membrane oxygenation bridging on postoperative acute kidney injury after lung transplantation

Abstract Venovenous extracorporeal membrane oxygenation (VV-ECMO) bridging to lung transplant has the potential to reduce mortality among patients awaiting transplant. However, there continue to be notable morbidity risks, including acute kidney injury (AKI). This paper seeks to...

Natural variation in LuGnTL modulates the trade-off between plant height and seed size in flax (Linum usitatissimum L.)

Flax is an ancient crop cultivated for both fiber and oil, and it has undergone divergent selection into two distinct morphotypes: semi-dwarf oil flax with large seeds and tall fiber flax with small seeds. However, the genetic architecture underlying the trade-off between plant h...

Dynamic Modeling and Self-Tuning Fuzzy Skyhook Control of a Metro Vehicle with a Flexible Carbody and Semi-Active Suspension

Lightweight metro carbodies may exhibit elastic modes within ride-comfort-relevant frequency bands, limiting semi-active suspension controllers tuned offline for nominal conditions. This study proposes a skyhook-based parameter self-tuning fuzzy control (PSTFC) strategy for later...

From volatile to nonvolatile resistive switching in a ferroelectric second-order memristor

Ferroelectric memristors are promising candidates for neuromorphic computing, yet their practical application is hindered by the trade-off between the volatile synaptic plasticity required for learning and the nonvolatile retention needed for long-term data storage. Here, we demo...

Preoperative anxiety, sleep disturbances and postoperative delirium in cardiac surgery: A scoping review for nursing practice

Preoperative anxiety, sleep disturbances and postoperative delirium are common complications among patients undergoing cardiac surgery and are associated with adverse perioperative outcomes. This scoping review aimed to synthesise evidence on the relationship between these factor...

Prevalence of Biofilm-Forming Pseudomonas aeruginosa from Clinical Samples in Africa: A Systematic Review and Meta-Analysis

Background: Biofilms help Pseudomonas aeruginosa adhere to surfaces and form an extracellular polymeric matrix. P. aeruginosa infections are increasingly difficult to treat due to biofilm formation. This study seeks to ascertain the overall prevalence of biofilm-forming P. aerugi...

The Problem with Price Elasticity and Electricity Rate Design

For both electric utilities and regulators that oversee them, it is the elephant in the room—the issue that can never be discussed or even acknowledged. I am referring to price elasticity of demand. When a utility goes in for a rate case and is allowed a certain increase in reven...

Frequent Callers to Emergency Medical Services: an observational cohort study from Region Zealand, Denmark (2018–2025)

Frequent callers to Emergency Medical Services represent a small group of citizens who account for a substantial number of calls. Despite their impact, little is known about their characteristics and patterns of EMS use. This study aimed to examine frequency, dispatch outcomes, a...

MPR-MOPSO-ASFS: A Stable Multi-Objective Feature Selection Algorithm for Metabolomics

Background: Metabolomics data is inherently characterized by high dimensionality and small sample size. Existing multi-objective particle swarm optimization (MOPSO)-based feature selection algorithms suffer from two critical limitations: they generally neglect the stability of se...

Relationship of patellar tendon micromorphology with body anthropometrics and lower-limb range of motion in volleyball athletes

Context Volleyball athletes frequently perform jump-landings, which can lead to structural changes in the patellar tendon. However, the relationship between intratendinous morphology, anthropometrics, and lower-limb range of motion (ROM) in athletes remains unclear, and the dista...

Description of Elaiopezia olivaceobrunnea sp. nov. (Pezizaceae) and new collections of E. boudieri

New collections of Elaiopezia (Pezizaceae) species allow a better morphological and ecological circumscription of E. boudieri, as well as the discovery of an unknown taxon found in France and Germany, named E. olivaceobrunnea, well characterised by its smooth ascospores and asci...
