DISSECTING THE PROBLEM OF AGENTIC AI ACCOUNTABILITY:

In 2026, A. Stavropoulos accurately diagnosed the managerial gap in agentic AI: machines act at millisecond speed, institutions at the speed of meetings. Yet his commentary stops precisely where engineering begins — at the call to “take accountability into account.” The present w...

A Client-Side, Browser-Native Pipeline for Liveness-Gated Facial Verification and Geofenced Attendance in a Government Internship Setting: Multi-Signal Passive Fusion, Server-Side Verification, and a Post-Defense Security Hardening Case Study

This paper is a post-defense revision of a Design Science Research (DSR) study on a browser-native, client-side, layered verification pipeline built as an individual contribution within a larger Capstone attendance-monitoring system for the Directorate General of Customs and Exci...

Remote electroacupuncture conditioning protects the heart via fine-tuning the dual role of the SDF-1α/CXCR4 axis in myocardial ischemia–reperfusion injury

BACKGROUND: Remote electroacupuncture (EA) conditioning on forearm protects against myocardial ischemia-reperfusion injury (MIRI). However, the cardioprotective mechanisms of RIC have not been fully elucidated. This study aimed to investigate whether EA could balance the pro-surv...

Combined effects of material selection and surface engineering on the wear behavior of glass crusher blades in deposit return systems

Abstract The wear behavior of glass crusher blades used in deposit return systems was investigated by evaluating the combined effects of material selection and surface engineering. Eight different steels were tested under simulated glass-crushing conditions using a custom-designe...

PBH Scaffolding Theory: Primordial Black Holes Replace Particle Dark Matter

PBH Scaffolding Theory proposes that the large-scale gravitational scaffold of the universe is not an elementary dark-matter particle species but a primordial black-hole fog (asteroid-mass PBHs in unmodified Einstein gravity). Five independent gates operationalize scaffold comple...

General C(sp3)–C(sp3)Cross-Coupling of Primary Amines via in Situ Diazene Formation

Abstract Primary amines are among the most abundant and readily available functional groups, yet their direct use as alkyl cross-coupling partners remains underdeveloped. We report a general platform for C(sp3)–C(sp3) cross-coupling enabled by the in situ formation and visible-li...

From Implicit Latents to Explicit Physics: Retained Decoding with Budgeted Supervision in LeWorldModel

Joint-Embedding Predictive Architectures (JEPA) train world models to imagine action consequences in latent space, but the physical quantities they encode remain implicit and unreadable from the outside. We extend LeWorldModel (LeWM) with a shared decoder head on its latent, reta...

All-Order Polynomial First-Integral Rigidity on the Toda-Compatible Slice of a Chazy-Type Family

We classify, without an a priori degree bound, the polynomial first integrals of the autonomous third-order family $p'''+p p''+k(p')^2+\left(\frac{p^2}{4}-\sigma\right)p'=0, (k,\sigma)\in\C^2.$ This is the constant-shift slice characterized by $2K'(p)=p$ in the more general equat...

Effect of AlkaliMetal Ions and Salt Composition onStructural and Dynamical Properties of Ternary Electrolytes

Abstract Molecular dynamics simulations were employed to investigate the influence of alkali-metal ions (Li+, Na+, K+, and Cs+) and salt loading on the solvation structure, coordination environment, and transport properties of ternary electrolytes composed of a short-chain polyet...

A novel medical image segmentation network for colorectal polyp small targets and fuzzy boundaries

OBJECTIVES: To address the challenges of complex feature variations and unclear boundary definitions between segmented targets and surrounding regions in medical images, a novel segmentation model based on Deformable Large Kernel Convolutional Attention (D-LKA) and Transformer is...

Chemical profile and bacterial potential of Psidium cattleyanum leaf extract against multidrug-resistant Staphylococcus aureus

Abstract The increasing prevalence of multidrug-resistant (MDR) Staphylococcus aureus represents a major challenge for global public health and highlights the urgent need for new antimicrobial strategies. In this context, plant-derived compounds have emerged as promising sources...

Digital exclusion and health in older adults: a systematic review

Abstract Healthcare systems are turning increasingly digital. Digital exclusion restricts access to a wider range of health-related resources among older adults, which delays prevention and treatment, posing additional health challenges. The study aims to systematically review th...

Approaches to nonlinear programming problems: Taylor series expansion, RBF surrogate modeling, DOE-based dimensionality reduction, and adaptive domain splitting

<title>Abstract</title> Solving nonlinear constrained optimization problems efficiently remains a challenge. This paper describes a four-component method developed to address these difficulties: Design of Experiments (DOE) screening using L9 and L81 orthogonal arrays to eliminate...

From digital to physical model: testing of a workflow for case-specific 3D-printed bone simulants

Bone simulants are used for a variety of purposes in wound ballistic experimentation. Synthetic simulants have several advantages over biological (either human or animal) material. Generic synthetic simulants are available, but the shapes and sizes of these materials cannot cover...

Extending SHARC to Periodic Systems: A SHARC–VASPInterface for First-Principles Nonadiabatic Dynamics

Abstract Nonadiabatic effects arising from the breakdown of the Born–Oppenheimer approximation govern a wide range of photoinduced processes in molecules and materials. While trajectory surface hopping has become a standard tool for simulating excited-state dynamics in molecular...

Effects of medium-induced osmotic and nutrient stress on cyanogenic glycosides in flax (Linum usitatissimum)

<title>Abstract</title> Background Cyanogenic glycosides (CGs) are multifunctional plant metabolites involved in defense, nitrogen turnover, and stress responses. Study examined effects of medium-induced osmotic and nutrient stress on cyanogenic glycosides in flax (Linum usitatis...

Attention-Like Hebbian Learning from Quantum Probability Flow and Quantum-Annealer Tests

We propose a quantum probability-flow principle for deriving local learning rules in associative memory. A transverse field defines leakage channels from data states, and minimizing the measured survival loss gives stability-driven updates. For imaginary-time, dephased dynamics,...

HarnessingDiamond Surface Features for Dense andAligned NV Ensembles

Abstract Controlling nitrogen doping in diamond is key to advancing nitrogen-vacancy (NV) center devices. We harness the hillock, a typically undesirable surface feature, to incorporate high densities of grown-in, aligned NV centers on a (001)-oriented substrate. Enhanced cathodo...

<title>Abstract</title> <bold>Background:</bold> Dental anomalies (DAs) are clinically relevant developmental anomalies that impact oral health and overall quality of life. <bold>Objectives</bold> : Our study aimed to determine the prevalence of dental anomalies among schoolchild...

Effects of pre-spawning heat stress on the fecundity of Acropora aspera

<title>Abstract</title> Repeated bleaching events driven by heat stress have caused extensive coral mortality and long-term impairment in survivors. Following bleaching, larval production and recruitment decline, undermining reef recovery. On the Great Barrier Reef, such heat-str...
