Impact of Prolonged Continuous Stress Exposure on Immune Function and the Gut Microbiome in a Perpetual Avoidance of Water on a Wheel Mouse Model

Both the immune system and gut microbiome play important roles in the physiological response to stress, yet their interplay under conditions of long-term continuous stress remains poorly understood due to the lack of suitable experimental models. We employed our previously develo...

Atomically thin amorphous carbon with an ultralow dielectric constant

Two-dimensional (2D) materials could replace conventional electronic components. Key advances have already been made in applying 2D materials to integrated circuits, but a robust, atomically thin ultralow-k dielectric remains crucial for further circuit scaling. Minimizing parasi...

Explicit and refined QUBO modeling of anomalously reflective metasurfaces for annealing-assisted design optimization

This paper presents an annealing-assisted optimization framework for anomalously reflective metasurface design based on quadratic unconstrained binary optimization (QUBO) modeling. First, an explicit QUBO formulation is derived under the physical optics (PO) approximation, enabli...

New insights into the optimization of bimodal powder for the enhancement of green body densification via binder jetting

Powder preparation plays a critical role in the densification of products fabricated via binder jetting (BJ) and strongly influences the performance of the end product. Bimodal powder mixing using particles of different sizes represents an effective approach to improve powder pac...

A Tert ‐Alkyl Terephthalate Derivative as a Universal Degradable Unit for Condensation Polymers

ABSTRACT Incorporating cleavable triggers into the backbones of parent polymers enables programmed degradation, offering a pathway to chemically recyclable plastics. Although various triggers have been reported to date, simple esters bearing a C─O bond cleavable by photocatalytic...

Machine-Learning Analysis of the Electronic Structure of Atomically Thin MnTe Films from Scanning Tunneling Spectroscopy

Layered two-dimensional (2D) van der Waals magnetic crystals based on 3d transition metals and chalcogenides are typically synthesized by chemical vapor transport, while establishing epitaxial, layer-by-layer growth under vacuum remains essential for device applications. Here, we...

The widespread occurrence of nocturnal NOx accumulation under weak‑wind conditions revealed by a dense air quality monitoring network in Japan

Understanding the influence of meteorological conditions on surface nitrogen oxide (NO x ) concentrations is important. However, interpreting increases in NO x concentrations at night remains challenging under weak-wind conditions. These increases can be caused by changes in emis...

Random forest-based lithology identification using geophysical well logging data along a borehole in a coastal aquifer in Suruga Bay, Japan

Abstract Machine learning techniques have attracted attention for lithology identification, which is fundamental for understanding geological structures. However, the efficacy of machine learning-based lithology identification, specifically in deep (several hundred meters) coasta...

ElectronicStructure of Cu-Phthalocyanine Metal–OrganicFramework

Abstract Metal phthalocyanine metal–organic frameworks (MPc-MOFs) possess a crystalline structure consisting of stacked molecular layers that form a square lattice composed of metal phthalocyanine (MPc) units. The unique structure of these MPc-MOF molecular layers is theoreticall...

Spatial control of PEG-lipid interfaces at cell surface enables on-demand adhesion and enzymatic detachment of suspension cells

Suspension cells are widely used in biomedical research and cell-based therapies; however, their lack of stable adhesion to substrates limits their efficient handling, including gene delivery and downstream processing. Although surface engineering approaches have been studied to...

Two stress-responsive kinases suppress ferroptosis by activating antioxidant programs under mild oxidative stress

Cancer cells maintain chronically elevated levels of reactive oxygen species (ROS) while relying on robust antioxidant programs to preserve redox homeostasis and viability. Although therapeutic strategies that disrupt this balance to induce lethal oxidative stress and ferroptosis...
