Enhanced Room-TemperaturePhosphorescence from CarbonDots Embedded in a Robust SiO2 Matrix

Abstract Carbon dots (CDs) represent a rapidly advancing class of fluorescent nanomaterials. Due to the dominant nonradiative decay channels of the triplet excited state of CDs, these materials generally exhibit no observable phosphorescence (PH) or delayed fluorescence. Here, we...

PrismaticNa-Ion Coordination in the Sulfide-ChlorideSolid Electrolyte Enables Fast Na-Ion Transport

Abstract Designing halide solid electrolytes with high ionic conductivity and robust electrochemical stability is crucial for advanced all-solid-state sodium-ion batteries. Currently, most sodium-based halide conductors suffer from the limited ionic conductivity. In this work, we...

Spatiotemporal dynamics of the tumor microenvironment in hepatocellular carcinoma during combination immunotherapy

Background: Atezolizumab plus bevacizumab (ATZ/BEV) is a standard first-line therapy for advanced hepatocellular carcinoma (HCC); however, many patients do not achieve meaningful tumor regression. The temporal and spatial immune remodeling associated with ATZ/BEV remains poorly u...

Early detection of foot rot on sweet potato based on auto-fluorescence of phytoalexin

Sweet potato foot rot is difficult to detect at the pre-symptomatic stage because visible symptoms are minimal or absent, whereas conventional approaches are often destructive or unsuitable for rapid screening. In this study, a UV fluorescence imaging workflow was developed for p...

Concurrence in Neutron–Proton Scattering for Polarization-Induced Mixed States

We investigate spin entanglement generated in neutron–proton scattering by evaluating the concurrence from the scattered two-nucleon density matrix. While previous studies mainly discussed pure initial spin states, the present work extends the analysis to polarization-induced mix...

Monolithic Porous Polymer Architectures for Visible‐to‐UV Upconversion‐Driven Photochemical Reactions

ABSTRACT Triplet–triplet annihilation‐based photon upconversion (TTA‐UC) expands the accessible spectral window for photochemical transformations by generating high‐energy photons from low‐energy excitation. Although TTA‐UC has been widely demonstrated in solution and in various...

The Zooplankton International Geospatial dataset: A global repository of spatiotemporal freshwater zooplankton community composition data from lakes and reservoirs to support ecological research

Abstract Zooplankton transfer substantial energy in aquatic food webs and are used as indicators of environmental change. Syntheses of zooplankton community dynamics globally require datasets that span a wide range of environmental gradients; however, these datasets are limited d...

The syntax-phonology interface of Left Branch Extraction

Abstract Locality of dislocation has been one of the central issues in linguistics since Ross’s (1967. Constraints on variables in syntax. Cambridge, MA: MIT dissertation) seminal paper. One of the locality conditions that Ross describes is the Left Branch Condition, which prohib...

Impact of a Stratocumulus Scheme on Clouds and Feedbacks in MIROC7

Abstract Marine stratocumulus (Sc) clouds exert a strong cooling effect on climate by reflecting solar radiation, yet many climate models underestimate their amount and cause uncertainty in equilibrium climate sensitivity (ECS). Herein, we show that incorporating a physically bas...

Differential Models of Time-Variant Tumor Growth Trajectories with Sensitive, Persister, Resistant Cell Population in Lung Tumors During Tyrosine Kinase Inhibitor Therapy

Modeling the dynamics of three tumor cell populations, i.e., sensitive, persister, and resistant tumor cells, during molecularly targeted therapy with tyrosine kinase inhibitors (TKIs) would be valuable for adjusting treatment plans for patients with epidermal growth factor recep...

Trade-off between repository footprint and radiotoxicity in geological disposal of vitrified high-level waste from spent MOX fuels: quantitative assessment of simplified minor actinide separation

Radioactive waste management remains a critical challenge for the sustainability of nuclear energy systems, particularly for closed fuel cycles utilizing mixed oxide (MOX) fuel. MOX fuel contains significantly higher concentrations of minor actinides (MAs) and heat-generating nuc...

Monitoring pedestrian walking dynamics under environmental and policy influences in urban spaces

Abstract Understanding how environmental conditions and policy interventions jointly shape pedestrian mobility is essential for designing resilient, adaptive, and human-centered urban spaces. This study presents a computer-vision framework that extracts pedestrian trajectories fr...
