Comparative CO2 Electroreduction by Cu7 Nanoclusters across Molecular, 1D, and 2D Reticular Architectures

Abstract Reticular chemistry is typically invoked to organize molecular building blocks, yet its ability to reprogram the intrinsic reactivity of atomically precise metal clusters remains largely unexplored. Here, we demonstrate dimensional reticulation as a decisive lever for tu...

Switchable Electroosmotic Delivery via Capillary Shrunken Reduced Graphene Oxide Membrane

Abstract A capillary-force-assisted reduced graphene oxide (rGO) membrane is developed for electrically controlled electroosmotic flow (EOF). By combining capillary drying with subsequent freeze-drying, structural shrinkage is used to continuously control the pore size and channe...

Tandem Ru–Tm Sites on MoS 2 Tune Entropy–Enthalpy Tradeoff for Enhanced Alkaline Hydrogen Evolution

ABSTRACT Rare earth (RE) regulation has emerged as an effective strategy for improving hydrogen evolution reaction (HER), but RE kinetic behaviors are widely discussed from an adsorption energy perspective, with neglectful apparent activation energy ( E a ) and entropy (Δ ‡ S ) c...

Potent Antivirals for Respiratory Syncytial Virus Detected via Peptide-Based Fusion Inhibitor Screening

Abstract The respiratory syncytial virus (RSV) causes fatal pneumonia in neonates, infants, and older adults. However, no approved antiviral drugs exist for RSV; furthermore, the currently available antibody-based therapies are expensive and do not provide complete protection aga...

Two-Reader Detection Method for Staggered Dual-Layer Bit-Patterned Magnetic Recording Media

Dual-layer recording doubles the effective areal density of bit-patterned magnetic media, but because both layers are sensed by a common reader, interlayer interference (ILI) is the dominant impairment. This paper presents a two-reader detection method for staggered, dual-layer b...

Carbohydrate-to-fat ratio is positively associated with comprehensive frailty across protein-intake levels in older adults

Abstract Purpose Diet influences frailty, and protein intake has been a prime focus of prevention. However, frailty remains prevalent, even among older adults with relatively high protein intake, suggesting the influence of remaining energy distribution between carbohydrates and...

Potential utility of more subtle microsatellite instability for predicting response to nivolumab in gastric cancer patients

The relationship between microsatellite instability (MSI) - high (H) and deficient DNA mismatch repair is, in fact, not straightforward. MSI observed in genome-edited cells carrying Lynch syndrome mutations is not so drastic as in typical MSI-H ( i.e. Type B mode) but uniformly m...

The Contact Frontier in Galactic Civilization Networks: Radial Structure and the Galactic Habitable Zone

The probability of interstellar contact depends not only on the abundance of technological civilizations but also on their spatial connectivity. Treating civilizations as nodes linked whenever their separation is smaller than the distance a signal travels within a communicative l...

Lifetime Distributions in Galactic Civilization Networks: A Hierarchy of Moments and Connectivity Thresholds

The Drake equation uses only the mean lifetime of a communicating civilization. Do contact and connectivity depend on the mean alone? Here the single lifetime and communication range of earlier work become a joint distribution at fixed mean. Abundance depends on the first moment...

First-Principles Calculations of the Magnetocrystalline Anisotropy Energy in Disordered Alloys Using Wannier-based Coherent Potential Approximation

We present a method for calculating the magnetocrystalline anisotropy energy (MAE) of disordered alloys using Green’s functions constructed from Wannier Hamiltonians within the coherent potential approximation (Wannier-CPA). The MAE of a disordered alloy system is obtained from t...

Piezo1 Activation by Yoda1 Inhibits Mechanosensitive ATP Release in Human Urothelial Cells and Bladder Overactivity in Rats with Bladder Outlet Obstruction

Urothelial ATP release during bladder filling modulates afferent nerve activity and detrusor contractility to regulate the micturition reflex, yet the upstream mechanosensory mechanism linking distension to ATP release remains unclear. Here we investigated the role of Piezo1 in r...

Emotional arousal predicts pupil responses following a single attention shift between bright and dark moving stimuli

Pupil size is widely used as an index of emotional arousal but is also strongly influenced by luminance and attention to bright or dark stimuli. We examined whether trial-by-trial subjective emotional ratings predicted pupil responses when affective sound onset coincided with a s...

Cesarean delivery and overweight at 6 years of age: a prospective cohort analysis of the Japan Environment and Children’s Study

Abstract Cesarean delivery (CD) has been suggested as a potential risk factor for childhood overweight and obesity; however, evidence beyond early childhood remains inconsistent. We examined the association between CD and childhood overweight at age 6 years and explored early lif...

Octahedral tilt relaxation decoupled from lattice parameters in epitaxial perovskite oxide films

Epitaxial strain in perovskite oxide thin films is conventionally understood through lattice parameter modulation, characterized by the c / a ratio of the pseudocubic cell. However, internal atomic arrangements such as octahedral tilting can relax independently, a phenomenon that...

Unsupervised machine learning for automated crystal orientation mapping on noisy 4D-STEM data

Abstract Four-dimensional scanning transmission electron microscopy (4D-STEM) is a high-throughput measurement used to comprehensively acquire diffraction patterns across a region of interest in a specimen. While the measurement is useful for identifying crystallographic microstr...

Host–Dopant Engineering of Ce 4+ ‐Dominant Y 3 (Al,Ga) 5 O 12 :Ce,Mg Scintillators for High‐Performance X‐Ray Imaging

ABSTRACT Fast scintillators are essential for advanced X‐ray imaging and time‐of‐flight techniques. Although stabilizing Ce 4+ ions in garnet hosts is an effective strategy for suppressing the afterglow and accelerating scintillation, it often introduces quenching pathways that r...

Atomically Precise Metal Nanoclusters: Advancing Electrocatalytic Nitrate-to-Ammonia Conversion

Abstract Driven by the growing need for sustainable ammonia production and effective nitrate remediation, the electrocatalytic nitrate reduction reaction (NO3RR) has emerged as a promising technology. This process enables the conversion of nitrate pollutants into ammonia under mi...

Seasonal variation in day-to-day blood pressure variability: large-scale within-individual home blood pressure data

Abstract Day-to-day home blood pressure (BP) variability predicts cardiovascular and cognitive risk, but whether it shows seasonal variation within the same individual remains uncertain. We examined its seasonal patterns using repeated personal health record measurements. We anal...
