Terrain‐Adaptive Quadrupedal Locomotion Using Model Predictive Control With Impedance Control and SINDy Model Enhancement

ABSTRACT Quadrupedal robots operating in unstructured environments require adaptive control systems that can handle diverse terrain conditions without prior surface characterization. This paper presents an integrated control architecture that combines Model Predictive Control (MP...

Impacts of climate and reduced ice cover on trophic structure and community dynamics in a high latitude lake

Abstract Climate-driven environmental change can alter both the structural and dynamic properties of ecological communities. With ongoing warming, high-latitude lakes experience reduced ice cover, higher growing-season temperatures, and altered hydrology, potentially triggering c...

Iron Isotopes Reveal Fe Export Driven by Change of Tropical Weathering Regime

Abstract Unraveling paleoenvironmental signals recorded in laterites is crucial for quantifying weathering‐driven elemental fluxes at the Earth's surface. New stable iron isotope data (δ 56 Fe), combined with (U‐Th)/He ages in Fe‐oxides from a ferruginous duricrust from French Gu...

Establishing anthropometric growth references for school-going children aged 3–13 years in southern Thailand using GAMLSS

Version 1.1.0 adds figure generation (Figures 3–5), the sensitivity analysis behind Supplementary Table S2, and the AICc and HQIC criteria reported in Table 2. No results from version 1.0.0 are altered.

Global experiences, intelligent technologies: the development of an AI-enabled customer experience (AICX) scale

Purpose This study introduces artificial intelligence–enabled customer experience (AICX) conceptualised as distinct, multidimensional form of customer experience arising from interactions with AI-enabled technologies and develops and validates a novel scale to measure the phenome...

Digital Divide and Educational Inequality in Asia: A Cross-Country Secondary Data Analysis of Connectivity, Access, and Student Achievement

The increasing reliance on digital technologies in education has intensified concerns regarding unequal access to digital resources across countries, particularly in developing regions. While digital connectivity has the potential to enhance learning opportunities, disparities in...

Machine Learning-Based Prediction of Sleep Quality in Patients with Multiple Sclerosis

Background/Objectives: Sleep disturbances are common but frequently underrecognized in multiple sclerosis (MS), independently predicting reduced quality of life and worsening fatigue, cognitive impairment, and depression. While pain, nocturia, fatigue, and mood symptoms are estab...

Arming the archipelago: explaining A2/AD divergence in the South China Sea

How do secondary powers develop anti-access/area denial (A2/AD) capabilities when facing asymmetric threats? This article explains variation in Southeast Asian maritime defense strategies through a novel framework that distinguishes between anti-access (A2) and area denial (AD) b...

Not the whole picture? Modern slavery crimes recorded and charged by the police

Since 2013 the British government has repeatedly promised to eradicate modern slavery. Far from diminishing as a social problem, the number of cases of modern slavery officially recorded has grown every year. We analysed 3,304 suspected modern slavery incidents reported to two po...

Learned vs. Heuristic Thresholds for Cascade Retrieval Routing in Indian Legal Question Answering

Retrieval-Augmented Generation (RAG) systems for legal question answering increasingly combine dense vector retrieval with knowledge-graph retrieval to support both direct information lookup and citation-heavy relational reasoning. In cascade retrieval, vector search is performed...

Global Continuation Across the Kerr Ring: Axiom Sets, Junction Data, and Disk-Crossing Geodesics

With the stationary Killing field continued from $r>0$, the fixed-$M$ Boyer--Lindquist continuation of Kerr has a second asymptotically flat end with ADM mass $-M$. We separate this metric statement from signed Komar conventions and organize the data required for other continuati...

Surface Biofunctionalization of Additively Manufactured Medical-Grade PEEK by GelMA Grafting for Maxillofacial Reconstruction

Polyetheretherketone (PEEK) is increasingly attractive for patient-specific maxillofacial reconstruction because its elastic modulus approximates cortical bone, it is fully radiolucent, and it is compatible with additive manufacturing; its principal limitation is bioinertness, as...

Identification of the Down Syndrome Critical Region 3 Gene as a Mammalian Cell Size Regulator

Using a genetic screening approach based on an inducible gene-activating system and cell sorting, Down syndrome critical region 3 (DSCR3) was isolated as a gene whose overexpression increased cell size. Fibroblasts derived from individuals with Down syndrome (DS) exhibit elevated...

Self-Sustaining Quantum Information Engine Operating on Discrete Spacetime Voxels via Toroidal Geodesics and Interaction-Free Measurement

This paper proposes a theoretical model for a self-sustaining Quantum InformationEngine (QIE) operating on discrete, volumetric spacetime at the Planck scale (voxels). Bydirecting photons into toroidal spiral trajectories (toroidal geodesics) within a localizedKerr-metric curvatu...

Complementary Physical Dimensions of Vrancea (Romania) Intermediate-Depth Ground Motions: Intensity Measures and Their Implications for Sustainable Structural and Geotechnical Risk Assessment

Ground-motion intensity measures (IMs) are key parameters for seismic hazard and risk assessment. However, seismic hazard characterization and code-based design spectra commonly rely on a limited set of parameters, particularly peak ground acceleration (PGA), spectral acceleratio...

Assessing the Effects of Root Preparation Methods and Irrigation Strategies for Urban Tree Growth and Establishment

Drought and constrained municipal budgets are increasing demand for establishment practices that conserve water and labor. This study quantified trade-offs between inputs (water, labor, cost) and tree outcomes across irrigation methods and root-ball correction practices during es...

2D hydrodynamical simulations of Be star decretion disc formation through boundary layer effects

Abstract Be stars are massive main-sequence stars rotating close to their breakup rate. They possess a decretion disc of material built up due to mass loss from the star, however, there is not a consensus to the mechanism responsible for the formation of the disc because of their...

Pollinator behaviour and morphology to understand pollination niche partitioning in co‐occurring closely related plant species

Abstract Pollinator foraging behaviour shapes a plant's pollination niche, with direct consequences for natural selection and plant evolution. However, the extent to which individual‐ and species‐level pollinator behaviour, and the drivers of such behaviour, actually influence po...

A Review of Thermal Management in Modern Data Centres: Water Usage Effectiveness and Heat Transfer Coefficients

Rapid growth in artificial intelligence, machine learning, and high-performance computing has substantially increased data centre rack power densities, resulting in higher heat generation and more demanding cooling requirements. As water remains widely used in many cooling system...

Information Loss in Scalar Monetary Aggregation: A Tensorial Langevin Framework for Financial Shock Propagation and Policy Targeting

We develop a tensor-based dynamical framework for monetary flows in multi-sector, multi-agent economies and quantify the information destroyed when the monetary state is reduced to a scalar aggregate. The state is a third-order tensor encoding capital flows across sectors, agent...
