Representation choice shapes the interpretation of protein conformational dynamics

Abstract Molecular dynamics simulations provide detailed trajectories at the atomic level, but extracting interpretable and robust insights from these high-dimensional data remains challenging. In practice, analyses typically rely on a single representation. Here, we show that re...

Alterations in Coal Permeability and Adsorption Capacity Post Oxidation Treatment: Insights into Enhancing Coalbed Methane Production

Abstract Organic matter dissolution by oxidants can enhance the coal permeability. However, as coalbed methane (CBM) is predominantly reserved in the adsorbed state, the organic matter dissolution changes the adsorption–desorption equilibrium, thus affecting the CBM production. C...

Scalp Topography of Event-Related Potentials Reveals Differences in Audiovisual Speech Processing in Autistic and Non-Autistic Children

Abstract Purpose In our prior work, conventional event-related potential (ERP) responses to audiovisual versus auditory-only speech were found to explain variance in language abilities in autistic and non-autistic children but failed to differentiate autistic children from non-au...

Comparative lipidomic and transcriptomic analyses reveal distinct regulatory effects of tree nut oils on hepatic lipid metabolism in high-fat diet-fed mice

Tree nut oils from the Juglandaceae family are rich in unsaturated fatty acids and bioactive components, yet their metabolic effects under high-fat diet (HFD) conditions remain incompletely understood. This study compared the effects of walnut, pecan, hickory, and soybean oils in...

An in-feed oral glucose test increases post-prandial high molecular weight adiponectin concentration in horses

Abstract Adiponectin is a fat-derived adipocytokine that has been associated with laminitis risk in ponies. Factors that affect sampling timing for measurement of adiponectin concentration have been inadequately investigated. This study aimed to determine the effect of an oral gl...

Acute Effects of Impella 5.5 on Biventricular Filling and Pressure–Volume Area in Patients With Heart Failure Associated Cardiogenic Shock

Use of Impella 5.5 in patients with decompensated heart failure-associated cardiogenic shock (ADHF-CS) is increasing as a bridge to advanced therapies. The effects of maximal trans-valvular unloading on biventricular filling and pressure–volume area (PVA) in ADHF-CS are poorly un...

Investigation of the Effects of Interactions Between Deltamethrin and Acrylic Paint Particles on Embryonic Development in Xenopus laevis

The co-occurrence of pesticides and paint-related contaminants in aquatic ecosystems may result in interactions that modify their individual toxic effects; however, the developmental consequences of their combined exposure remain insufficiently understood. This study investigated...

Diagnostic Utility of Full‐Length BP180 and Native BP180 ‐α6β4 Integrin Complex ELISAs in Serologically Inconclusive Mucous Membrane Pemphigoid

ABSTRACT Mucous membrane pemphigoid (MMP) is a chronic autoimmune subepithelial blistering disorder of mucosal surfaces that can cause irreversible scarring, blindness, or dysphagia. Early diagnosis is challenging because histopathology is nonspecific and conventional BP180 NC16A...

Drastic Improvement in Carrier Lifetime (>50 ms) and Stability of Poly‐Si‐Passivated n‐Type Cz‐Si Wafers by a Simple Belt‐Line Furnace Annealing Step

We examine the stability of the carrier lifetime of n‐type Cz‐Si wafers with symmetrical n + ‐poly‐Si layers on silicon oxide passivation. Such layers are used in today’s standard industrial TOPCon solar cells and probably in next‐generation IBC cells. Firing in an industrial bel...

E8 Polar Windmill Harmonic Sieve: Optimal Hamiltonian Path Predictor — E8 Intelligence Research

The polar dual structure underlying the windmill rotation can be mapped onto the E8 root system through stereographic projection from the 240-vector lattice onto a complex plane, where the rotating line becomes a 132Hz harmonic probe sweeping resonant nodes. Phi-coupled phase coh...

Folded futures: the exquisite corpse of citizenship and the emergence of planetizen

This paper introduces the planetizen as a speculative figure of more-than-human planetary belonging, emerging not through coherence but through rupture, absurdity, and relational composition. Drawing on a semester-long collaboration with students in the Planetizing Citizenship co...

Device-aware compensation of nonideal spintronic synapses for electrocardiogram classification using spiking neural networks

Spintronic synapses offer a promising route toward low-power neuromorphic hardware for edge intelligence. Their nonvolatility, multilevel tunability, and compatibility with event-driven spiking neural networks (SNNs) make them attractive for temporal biomedical signal processing....

Structural and energetic signatures of SO2 and CH4 incorporation in imidazolium-based ionic liquids

A systematic molecular dynamics study of sulfur dioxide (SO2) and methane (CH4) incorporation in 24 imidazolium-based ionic liquids is presented, spanning different anion families and cation alkyl chain lengths. The two gases represent limiting cases of solvation behavior in ioni...

Remission Trajectories During Low-Intensity Cognitive Behavioural Therapy for Obsessive–Compulsive Disorder: A 2-Year Naturalistic Follow-Up Study

Background and Objectives: Cognitive-behavioural therapy (CBT) for obsessive–compulsive disorder (OCD) has primarily been evaluated in short-term, high-intensity treatment protocols. However, remission trajectories during low-intensity CBT (LiCBT) delivered in routine clinical pr...

Position: AI Systems Should Be Designed to Develop Their Users, Not Just Assist Them

Human-facing AI systems are mainly designed and evaluated for what they do for users, and seldom for what sustained use does to users' own capabilities. Evidence that AI use can erode, preserve, or improve human capability is accumulating across several fields, but it remains sca...

Stock market prediction with machine learning and deep learning models: task design, model alignment, and theory integration

Recent advances in machine learning (ML), deep learning (DL), and hybrid models have accelerated research on stock market prediction. However, existing reviews largely compare algorithms while giving limited attention to alignment among prediction tasks, data, models, evaluation,...

From Geneva to São Paulo: Charles Harper, Jaime Wright, Paulo Arns and the Role of the World Council of Churches in the Ecumenical Resistance to Latin American Dictatorships

From the 1970s to 1980s, when several countries of the Southern Cone were under repressive military dictatorships inspired by the Doctrine of National Security, the World Council of Churches (WCC) played a fundamental role in denouncing human rights violations in Brazil and other...

Digital Health Infrastructure and Patient Privacy: Is Consent Under the Ayushman Bharat Digital Mission Sufficient to Protect Medical Data?

Abstract India has built one of the world’s largest digital health systems in about six years. By mid-2026 the Ayushman Bharat Digital Mission (ABDM) had issued over 93 crore Ayushman Bharat Health Account (ABHA) numbers and linked more than 104 crore health records. Its privacy...
