Generalized Steady-State Equation for Multi-Species Ion Transport Across A Dual-Compartment System

The Nernst and Goldman-Hodgkin-Katz (GHK) equations are the standard closed-form expressions for electrochemical equilibrium/steady-state across membranes but both rely on the assumption of dilute ion concentrations and do not account for ionic size or excluded volume effects. He...

UG.NUG

A short version, The voice of the Universe, is available on this platform: https://doi.org/10.5281/zenodo.21486180 . The CMB (cosmic microwave background) does not display the characteristics of a fossil but rather those of the GRID, the unnamed substrate Faraday referred to. The...

Comparative Study on Dynamic Mechanical Behavior and Power-Law Versus Johnson–Cook Constitutive Models of Quenched 42CrMo Steel

This study systematically investigates the dynamic mechanical behavior and constitutive modeling of low-temperature quenched and tempered 42CrMo steel under high-strain-rate and high-temperature conditions. Dynamic compression tests were performed using a split Hopkinson pressure...

Prevalence of Urinary Incontinence in the United States 2015–2020

Importance Urinary incontinence (UI) affects quality of life and imposes substantial health care costs. Updated U.S. prevalence estimates are needed, as national data are more than a decade old. Objective The objective of this study was to estimate the weighted prevalence of symp...

From space and voice to audience and influence: Methodological approaches to inclusive co-research with young children

This paper presents a methodological reflection on an arts-based practitioner inquiry project conducted in an inclusive early childhood setting in Australia. Drawing on Lundy's model of participation, describing space, voice, audience and influence, the paper explores how researc...

Pros and Cons of Digital Marketing

Digital marketing is the marketing of products or services using digital technologies, mainly on the Internet, but also including mobile phones, display advertising, and any other digital medium. Digital marketing’s development since the 1990s and 2000s has changed the way brands...

Chicken Nation: Permissibility, Power, and the Social Life of Meat in India

This article examines the cultural and political significance of chicken in contemporary India, situating its circulation within histories of caste hierarchy, religious distinction, and majoritarian politics. While scholarship has foregrounded beef as a site of prohibition and pu...

Paradoxes of Naive Set Theory and Their Resolution in Δ‑Ontology: From the Structureless Point to the Structural Quantum

This paper examines the classical paradoxes of naive set theory: Russell’s paradox, the barber paradox, the Grelling–Nelson paradox, the Burali‑Forti paradox, as well as the Banach–Tarski paradox and Zeno’s paradox (Achilles and the tortoise). It is shown that their emergence is...

Developing Structurally Uniform Nitrogenous Model Systems to Interrogate the Metal-Free Oxygen Reduction Reaction

Abstract Oxygen reduction reaction (ORR) is a kinetically sluggish reaction under uncatalyzed conditions. Numerous studies have revealed that mixtures of N-doped moieties in graphene improve ORR activity and selectivity. However, due to the surface heterogeneity of N-doped carbon...

Iron ore pellet firing temperature prediction and abnormality diagnosis based on interpretable machine learning

Accurate control of firing temperature is essential for quality, efficiency and energy consumption in iron ore pellet production. Traditional methods that rely on measured temperatures are limited by sparse measurement points, time lag and signal fluctuations. This study proposes...

Liquefaction-Induced Lateral Spreading Demands on Deep Foundations of Waterfront Structures

Waterfront structures such as port terminals, quay walls, bridge piers, marine jetties, and container handling facilities are frequently constructed on loose saturated sandy deposits that are highly susceptible to liquefaction during strong earthquake events. Earthquake-induced l...

Prevalence of Early Childhood Caries among 3–5-year-old Children in Qassim, Saudi Arabia: A Cross-sectional Study

Abstract Background: Early childhood caries (ECC) is one of the most common chronic conditions affecting young children and continues to represent an important public health challenge in Saudi Arabia. Population-based data on ECC in Qassim are limited. Objectives: To assess the p...

Beyond Central Subfield Thickness: Early Multi-Slice Optical Coherence Tomography Structural Response After Faricimab Injection in Real-World Diabetic Macular Edema

Objectives: We sought to evaluate the early efficacy of faricimab (Vabysmo®) in treating diabetic macular edema (DME) and to explore the predictive value of multi-slice optical coherence tomography (OCT) biomarkers for anatomical and visual outcomes. Methods: In this retrospectiv...

Investigación etnográfica de los espacios globales: Interrogantes metodológicos Para el estudio de poblaciones virtuales

Al igual que otros Estados-nación, la población de los Estados Unidos está compuesta por personas que viven tanto dentro como fuera de sus fronteras geográficas. El estudio de ciudadanos estadounidenses residentes en el extranjero presenta interesantes desafíos metodológicos: por...

Hydrationas a Structural Switch: Controlling MagneticCoupling and CO2 Photoreduction in Transition-Metal HalidePerovskites

Abstract Transition-metal halides are of particular interest because their partially filled d-orbitals, containing unpaired electrons, give rise to distinctive magnetic and electronic properties. Notably, hydration can act as a structural switch, inducing substantial modification...

Hidden-FFN on Apple GPUs: Compact Inference and Training from Homogeneous Sparse FFNs to WANDA-Pruned Language Models

This paper presents a first GPU implementation of Hidden-FFN (HFFN), whose companion CPU worksestablished an exact compact runtime for fixed sparse FFNs. Four Metal paths are evaluated: homogeneous FFNinference and training, then Pythia-70M, 160M, and 410M inference and training...

Global degree apprenticeships in higher education: comparative models for future-ready work-integrated learning

Purpose Growing concern over the mismatch between higher education outcomes and labour market needs has increased interest in degree apprenticeships as a work-integrated learning (WIL) model. This study comparatively analyses degree apprenticeship models in Germany, the United Ki...

The Meaning of Agricultural Technology For Millennial Farmers in Providing Food Security: A Case from Indonesia

The digital divide in the agricultural sector is a pressing issue that must be addressed urgently to achieve national food security through technological transformation. This study examines how millennial farmers in the UPTD BP4 Region III of Sleman Regency, Indonesia, perceive a...

Extended global area search algorithm for unimolecular reactions and multistep conformational transitions

In this study, we propose an extended Global Area Search (GLAS) algorithm for the automatic exploration of multistep transitions without specifying reaction coordinates in advance. The key concept of the original GLAS method is to introduce repulsive interactions among walkers re...

Redox‐Confined Interfacial Polymerization Enables Mechanically Robust and Self‐Adhesive Nanofilms
