An Efficient Deep Learning Method Based on a Hybrid LiDAR and Wearable Sensor Framework for Healthcare‐Oriented Human Activity Recognition

ABSTRACT Human activity recognition (HAR) is one of the most important components of modern healthcare monitoring systems, particularly for providing assistance to the elderly, rehabilitating patients, and continuously monitoring their health. The traditional method of activity r...

Multi-algorithm consensus clustering identifies four subphenotypes in sepsis-associated acute kidney injury

Sepsis-associated acute kidney injury (SA-AKI) is a highly heterogeneous syndrome with variable clinical trajectories and outcomes. Conventional staging systems, such as KDIGO, fail to capture this heterogeneity, limiting risk stratification and personalized management. We aimed...

Absolute knee extensor strength, not limb symmetry, predicts outcomes and defines a rehabilitation threshold after medial opening‐wedge high tibial osteotomy

Abstract Purpose To identify a clinically relevant body mass‐normalised knee extensor strength threshold after high tibial osteotomy (HTO) and examine how absolute strength and limb symmetry index (LSI) relate to patient‐reported outcomes (PROMs), dynamic balance and longitudinal...

Development of high-performance NIR-to-SWIR down-shifting Li$_3$Ba$_2$Gd$_3$(MoO$_4$)$_8$ :Yb$^{3+}$ /Tm$^{3+}$ and Yb$^{3+}$ /Ho$^{3+}$ for phosphor conversion LEDs

High-performance short-wave infrared (SWIR) phosphors are of increasing interest for phosphor-converted light-emitting diodes (pc-LEDs) used in sensing, imaging, and analytical applications. In this work, Li$_3$Ba$_2$Gd$_3$(MoO$_4$)$_8$ (LBGMO) phosphors co-doped with Yb$^{3+}$/T...

A foundation model for sleep-based risk stratification and clinical outcomes

Abstract Clinical sleep studies capture multiple physiologic signals, yet interpretation is often reduced to single summary measures of limited prognostic value, such as the apnea–hypopnea index. We present a foundation model that learns rich representations of sleep physiology f...

Recursive Minds in a Non‑Recursive World: A Structural and Geometric Framework for Understanding Autism, Cognition, and System Mismatch

This monograph presents a structural and geometric hypothesis on autism, cognition, and the architecture of modern systems. It proposes that many autistic experiences can be understood as the friction between recursive minds—those built on loops, layers, and deep patterning—and n...

Controlled-rail brachistochrones in non-stationary spacetimes: conformal symmetry, Kodama energy, and Vaidya dynamics

What is the fastest constrained worldline in a spacetime that is itself evolving? In a stationary spacetime the relativistic brachistochrone reduces to Fermat/Randers optics with a conserved rail energy supplied by a timelike Killing vector; in a dynamical spacetime no such conse...

Study of asynchronous transaction buffer in distributed banking system

Report of the The C3AI 2026 conference Abstract. This paper examines the behavior of a distributed asynchronoustransaction processing system integrating a high-load mobilebanking API with a legacy core banking system (CBS) with fixed throughputand periods of complete unavailabili...

CONFIDENTIALITY PROTECTION AND MANAGEMENT FRAUD DETECTION IN NIGERIAN BANKING INDUSTRY

The Nigerian banking industry has witnessed rapid digital transformation, which, while improving financial inclusion, has increased exposure to sophisticated fraud schemes. This study examined the influence of confidentiality protection on management fraud detection, focusing on...

Study on Microstructure and Wear Resistance Service Characteristics of AlCrN-Coated Relay Injection Mold

To address the problem of the short service life of relay injection molds caused by erosion of high-temperature glass fibers, AlCrN coatings were deposited on the surface of ELMAX mold steel using multi-arc ion plating technology. The surface morphology, cross-sectional morpholog...

Mitochondrial MAP4 regulates keratinocyte autophagy, apoptosis, and migration upon wounding through BCL2/SIRT5 functional coupling under hypoxia: an experimental in vitro study

Microtubule-associated protein 4 (MAP4) phosphorylates and translocates to the outer mitochondrial membrane, thus promoting keratinocyte migration under hypoxia; however, the underlying mechanism remains unclear. Given that a BCL2 homology 3-like (BH3-like) domain has been previo...

Analysing the linguistic landscape and status of indigenous languages at Wits School of Education

This study examines the linguistic landscape of the Wits University School of Education campus, with a focus on the representation and status of indigenous languages, specifically isiZulu and Sesotho, within the framework of the institution’s multilingualism policy. Employing a s...

THE PAIN OF BETRAYAL: AN ANALYTICAL STUDY OF PSALMS 41:9 AND 55:12–14 AND THE NKST TIV HYMN 2318 IN THE CONTEXT OF FAMILY CRISIS AND ITS IMPLICATIONS FOR CHRISTIANS IN AFRICA

This study examines the multifaceted trauma of close-range betrayal by executing a comparative, contextual analysis of Psalm 41:9, Psalm 55:12–14, and the Universal Reformed Christian Church in Nigeria (NKST) Tiv Hymn 2318. Employing an interdisciplinary methodology that integrat...

Phi-Resonant Epigenetic Topological Memory — E8 Intelligence Research

We hypothesize that the 240 E8 root vectors, when phase‑locked to a 132 Hz phi‑modulated carrier, form a decagonal topological scaffold that directly links the error‑correcting lattice of DNA replication to the symplectic routing of quantum nodes. Embedding this scaffold into chr...
