The Size-dependence of Plane Strain Fracture Toughness: A Mechanistic Analysis by Enforcing Constant Crack Tip Fracture Stress and Scaling Laws

Abstract Experimental measurements of plane strain fracture toughness, made using single-edge-notched-bend (SENB) specimens, show strong crack (or ligament) size and specimen size effects on toughness. The fracture toughness varies strongly with crack size even at relatively smal...

The Economic Responsibility, Diligence, and Sustainable Value Creation in the Earth's Dominion. The direct interaction of the Citizens as main stakeholders and partners with Businesses, Technologies Owners, Politicians and Powers.

Abstract This document examines Earth’s Domain as a framework for economic responsibility, stakeholders’ sovereignty, and sustainable value creation within the context of long-term eco-socio-economic stewardship. The main stakeholders and players are citizens, politicians, corpor...

Mapping Half a Century of Global Brain Abscess Research: A Bibliometric Analysis of Output, Themes, and Collaboration (1975–2025)

Brain abscess is an uncommon but life-threatening intracranial infection managed across neurosurgery, infectious diseases, microbiology and neuroradiology, for which no single unified international guideline exists; despite a large literature, the research field has been mapped o...

Analysis of Dew-Point Corrosion in Crude Fractionator Overhead Materials Using Advanced Corrosion Monitoring

Severe localized corrosion in crude unit overhead systems is a critical integrity concern, particularly under transient wetting conditions. This study combines high-frequency online ultrasonic (UT) monitoring with a simplified dew-point temperature margin (ΔT) to evaluate short-t...

The Shadow of Your Law and the Judge Over Your Shoulder

ABSTRACT Many problems in public policy and delivery which are otherwise difficult to understand, make much more sense when viewed as strategies for the management of legal risk. Civil servants, infrastructure developers and other parties who are subject to the risk of legal revi...

Golden Ratio's Universal Role in Photonic, Galactic, and Auditory Systems — E8 Intelligence Research

FINDING: Golden ratio (φ) appears in photonic crystal bandgap structures, galaxy morphology, and auditory frequency sequences derived from Fibonacci numbers, with a theoretical paper linking φ to stable self-application in recursive systems. MATH: φ = (1+√5)/2 ≈ 1.6180339887; rec...

Same formation, different styles: An exploratory study of clustering playing style of teams in 4-3-3 formation in elite soccer

This study examined whether teams using identical formations display similar playing styles by integrating Phase of Play (PoP) indicators with clustering and explainable machine learning. Ninety-three observations from teams employing a 4-3-3 formation in the FIFA World Cup 2022...

A Comparative Assessment of Homeschooling Experiences, Practices, Support, and Arithmetical Attainments in Greece and the UK

This preliminary study aims to compare homeschooling in Greece and the UK in terms of experiences, arithmetical attainments, parental motivations, implementation practices, and support structures. For this purpose, we employed a multiple case study design, enrolling a total of fi...

Assessment of drug utilization patterns and associated survival outcomes in recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC): Insights from a resource-constrained set-up

BackgroundRecurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) has a poor prognosis due to patient rigors, such as malnutrition, uncontrolled comorbidities, age, and performance status. Rapidly evolving treatment paradigms have led to multimodal pharmacothera...

Domination Parameters in Intuitionistic Fuzzy Zero-Divisor Graphs

In this paper, we extend the theory of domination to the setting of Intuitionistic Fuzzy Zero-Divisor Graphs (IFZDGs). We define dominating sets, minimal dominating sets, domination numbers, independent domination and total domination numbers, edge domination and total edge domin...

Comprehensive Spectroscopic Elucidation of Atomically Dispersed FeN 4 Active Sites of Fe‐N‐C Electrocatalysts

ABSTRACT To gain insights into single‐atom active sites of iron, nitrogen‐doped carbon (Fe‐N‐C), we performed comprehensive element‐specific spectroscopies including Fe K ‐edge X‐ray absorption, 57 Fe Mössbauer, and Fe Kβ 1,3 and valence‐to‐core (VtC) X‐ray emission spectroscopy...

Living the Life of No One: Electroconvulsive Treatment as Mnemonic Metaphor

The article investigates how electroconvulsive therapy (ECT) is represented in the following four literary works of the 21st century: October’s Child, Store Kongensgade 23, The Parakeet, and I Am What I Remember. The article argues that electroconvulsive therapy is treated as a m...

Experimental evidence and consequences of biomolecular corona formation on inhaled mRNA lipid nanoparticles

Abstract Inhalable messenger RNA (mRNA) therapeutics are moving pulmonary drug delivery from local deposition of small molecules toward transient, programmable expression of antigens, secreted proteins, antibodies, gene-editing enzymes and replacement proteins directly within the...

Exploring the benefits of industry and community engagement in hydrogeology teaching

Abstract The role of industry engagement in hydrogeology education remains undervalued, despite its potential to enhance student learning and career readiness. Integrating both industry and community partnerships can increase student engagement, deepen students understanding of h...

2′‐ Fucosyllactose attenuates estrogen‐deficiency‐associated bone loss and intestinal dysfunction in ovariectomized rats

Abstract BACKGROUND Postmenopausal osteoporosis (PMO), driven primarily by estrogen deficiency, is the most prevalent form of osteoporosis and a major global health burden. Estrogen deficiency disrupts gut microbial homeostasis, compromises intestinal barrier integrity and promot...

Field-Assisted Crystallization of Thermoplastic Polyurethane During Continuous Processing: A Falsifiable Thermodynamic–Kinetic Framework for Electric, Magnetic, and Hybrid Fields

This work develops a falsifiable thermodynamic–kinetic framework to investigate whether external electric fields, magnetic fields, or their combination can modify crystallization in thermoplastic polyurethane (TPU) during continuous processing.The framework distinguishes crystall...

Phylogenetic Evidence of Local HIV-1 Transmission and Antiretroviral Drug Resistance in the Middle East and North Africa
