A Consensus Multifeature Deviation Index for Specific Detection of Locomotor Perturbation From Individualized-Baseline Wearable Inertial Signals

This paper introduces the Gait Perturbation Burden (GPB), an unsupervised, consensus multifeature index that leverages individualized wearable inertial baselines to specifically detect locomotor perturbations with significantly reduced false positives during normal walking compared to single-feature or amplitude-only methods.

The Optimal Health-Investment Share: A Calibrated Planner’s Problem for Chronic Disease Burden

This paper develops and calibrates a continuous-time optimal-control model to demonstrate that cross-country disparities in chronic disease burdens and health spending are driven by structural differences in health-system productivity rather than policy errors, implying that simply increasing low-income countries' health spending without improving productivity yields minimal welfare gains.

Impact of small-scale irrigated vebetable production on household food and nutrition security

This study in Ethiopia's Kombolcha district demonstrates that participation in small-scale irrigated vegetable production significantly improves household food and nutrition security, as evidenced by a Propensity Score Matching analysis showing substantial increases in dietary diversity and food consumption scores among participating farmers compared to non-participants.

Coupled Effects of Boundary Corrugation and Hartmann Damping on Nanofluid Convection in Isosceles Triangular Enclosures: A High-Fidelity Thermophysical Analysis

This study employs a high-fidelity non-orthogonal Discrete Finite Element Method to demonstrate that temperature-dependent nanofluid models significantly outperform classical formulations in predicting MHD convection within wavy triangular enclosures, while identifying a critical Hartmann number threshold where electromagnetic forces suppress geometric boundary effects.

Phylogeny-associated codon evolution and conditional boundary dinucleotide structure in Platycerium plastomes

This study demonstrates that synonymous codon usage in *Platycerium* plastomes retains phylogenetic signals across geographic lineages while revealing a conserved, evolutionarily significant deficit of CpG dinucleotides at codon boundaries that persists despite strict controls for sequence composition and codon counts.
