Comprehensive gait characteristics on electromagnetic stance-control knee ankle foot orthosis in healthy individuals

Abstract Computer-controlled knee ankle foot orthosis (KAFO) has the potential to contribute to gait training and functional walking assistance by ensuring knee stability during stance while allowing knee flexion during swing; however, evidence regarding the gait characteristics...

Guideline-informed AI chat access and perceived mental effort in a simulated home-visit nursing task: a randomized controlled trial

Abstract Background Home-visit nurses often make autonomous clinical judgments in patients’ homes, where access to colleagues and evidence-based resources is limited. Guideline-informed artificial intelligence (AI) systems may facilitate access to clinical information, but eviden...

Ligand Field Induced Electronic Structure Modulation Enables Triple Redox Activity in Prussian Blue Analogue Molecular Magnet for Advanced Potassium Ion Battery

ABSTRACT Ligand field induced electronic structure modulation provides an effective pathway to tune the electrochemical functionality of Prussian Blue Analogue molecular magnets. Partial substitution of Fe by Co 2+ in Fe–C≡N–Fe framework forms cobalt iron hexacyanoferrate (KCoFeH...

Scattering of wobbling vortices

A bstract We investigate the dynamical role of internal vibrational modes in the Abelian Higgs model, focusing on how Derrick-type excitations modify vortex dynamics and scattering processes. We study the scattering of excited vortices and show that the interplay between spectral...

Dual northward overseas radiation from Japanese islands shaped the phylogeography of North-East Asian tree frog

The tree frog Dryophytes japonicus has a broad geographic distribution in northeastern Asia, comprising two major genetically divergent clades whose geographic boundary is located within the Japanese mainland. However, the evolutionary and adaptive mechanisms underlying this wide...

Flash Communication: Microwave-Assisted Synthesis of 2-Alkylphenyl-Substituted (NHC)CuCl Complexes

Abstract A base-free, microwave-assisted protocol using Cu2O and NHC·HCl salts is reported, which allows the synthesis of sterically less hindered 2-alkylphenyl-substituted (NHC)CuCl complexes, (SIMeortho)CuCl, (SIPrortho)CuCl, (IMeortho)CuCl and (IPrortho)CuCl; the use of dichlo...

A biomimetic leaf epidermis: Moldable knitted fabric based carbon fiber evaporator using weaving process for stable solar water desalination

The growing global demand for freshwater has driven the development of solar interfacial evaporation as an energy-efficient desalination strategy. In this work, a biomimetic carbon fiber–tencel mixed fabric evaporator is developed by mimicking the leaf epidermis in terms of direc...

Modification Technology for Exosome Membranes using Membrane-Curvature-Sensing Peptides and Its Application to Boron Neutron Capture Therapy

Abstract Extracellular vesicles such as exosomes are expected to be used as drug delivery vehicles, particularly in personalized medicine, due to their pharmacological advantages. However, the development of functionalization techniques for isolated extracellular vesicles—includi...

Comparative genomics of Actinomyces identifies an MRONJ-associated lineage characterized by variation in mfd

Abstract Although many cases of medication-related osteonecrosis of the jaw (MRONJ) have been reported, its pathophysiology remains unclear. Additionally, previous histological and metagenomic studies have implicated an association between MRONJ and Actinomyces ; however, verific...

Abdominal aortic calcification predicts anastomotic leakage after gastrectomy: a multicenter retrospective cohort study from the Hiroshima Surgical study group of Clinical Oncology

Anastomotic leakage (AL) is a critical complication following gastrectomy for gastric cancer (GC). Abdominal aortic calcification (AAC), a surrogate marker of systemic atherosclerosis and frailty, has been associated with AL only in single-center studies. This multicenter study e...

Effects of breakfast consumption of carbohydrates and caffeine on core body temperature profiles: a randomized controlled trial in habitual breakfast-skipping young adults

It has been suggested that breakfast influences daily physiological functions. However, evidence from human intervention studies remains limited. This study aimed to investigate the effects of breakfast composition, including carbohydrates and caffeine, on the core body temperatu...

Approximation in an Optimal Design Problem Governed by the Heat Equation

Abstract. This paper studies a two-material optimal design problem for the time-averaged duality pairing between a (possibly time-dependent) heat source and the weak solution of an initial-boundary value problem for the heat equation with a two-material diffusion coefficient, und...

Ultrafast Nuclear Rearrangement Governs Excited‐State Radial π‐Conjugation and Electron Transfer Dynamics in Organic Nanoring

ABSTRACT Radial π‐conjugation provides a unique platform for extending electronic delocalization in cyclic molecular architectures. Although radial π‐conjugation is relatively robust against static disorders in the ground state, both theoretical and experimental observations indi...

Validation and refinement of a biomarker panel for frailty assessment and prediction of muscle weakness in older adults

Abstract Frailty is a complex geriatric syndrome characterized by age-related declines in physiological function and cognitive reserve. To promote early prevention and intervention, minimally invasive and objective biomarkers that can detect frailty progression are required. We a...

An Algebraic Multivariable Model Matching Controller without Solving Diophantine Equations

This paper proposes an algebraically formulated model matching control method for MIMO systems with varying dynamic characteristics. Whereas conventional model matching control requires the solution of computationally demanding Diophantine equations, the proposed method derives t...

Endogenous calcium/calmodulin-dependent protein kinase II gamma and delta maintain Type II myofiber identity in adult mice

Skeletal muscle fiber identity is commonly characterized by coordinated contractile and metabolic programs, but the mechanisms that preserve this coordination in adult muscle remain unclear. We tested whether endogenous calcium/calmodulin-dependent protein kinase II γ and δ (CaMK...

Glutathione acts as an exometabolite that promotes growth recovery in fission yeast with defects in amino acid metabolism and cell polarity

ABSTRACT Microorganisms in nature form communities through diverse interactions, such as mutualism and competition, to adapt to their ecological environments. These interactions seem to be mediated by extracellular metabolites (exometabolites), yet the chemical and biological div...
