What Persists Matters More Than What Changes

A reusable world model need not reproduce every future observation exactly. What matters is which distinctions remain stable when forecasts, tasks, or trained instances change. Independently trained models may give different values yet preserve the same relation among matched int...

The chromatin-organizer Satb1 modulates regulatory T cell activity within the tumor microenvironment

Regulatory T cells (Tregs) are essential for maintaining immune homeostasis and preventing autoimmune diseases, but are also a major cellular constituent of the tumor microenvironment (TME) that facilitates cancer progression. Identifying differences in Treg subtypes to specifica...

Binding a Contested Nation: National Attachment and Cross‐Domain Solidarity in Taiwan

ABSTRACT This paper examines how national attachment shapes reciprocal solidarity across issue domains. We conceptualize solidarity as the willingness to share burdens out of a sense of mutual obligation to overcome collective adversity. Because the costs of solidaristic action v...

Resolving Erdős–Ulam Monochromatic Union-Closed Family Conjectures

We prove both Erdős–Ulam conjectures on monochromatic union-closed families, which are the two specific questions of Erdős Problem 1183. Every two-colouring of the subsets of a finite set contains a monochromatic union-closed family whose size grows faster than any fixed power of...

Quality of life in hyperkalemia: baseline analysis of a cohort study of management of hyperkalemia in patients with chronic kidney disease or heart failure in Japan

Abstract Background Hyperkalemia is common in chronic kidney disease (CKD) and chronic heart failure (CHF), often leading to treatment dilemmas regarding renin–angiotensin–aldosterone system (RAAS) inhibitors. Although potassium binders and dietary restrictions are central to chr...

Establishment of a seedling-based regeneration system for Taiwan oil millet (Eccoilopus formosanus) to support crop domestication and C4 biology

Taiwan oil millet (TOM; Eccoilopus formosanus) is a semi-domesticated orphan crop with potential as a resilient crop species and a model for C4 biology. However, the lack of an efficient tissue culture system has limited its use in genetic and functional studies. In this study, w...

Superinfection Exclusion Between Japanese Encephalitis Virus Genotypes I and III Occurs During Viral Entry

Superinfection exclusion occurs when a primary viral infection prevents subsequent infection of the same cell. Japanese encephalitis virus (JEV) comprises several genotypes that differ primarily in their envelope protein sequences, and a shift in predominance from genotype III (G...

Peak ground acceleration underestimates narrow-band seismic amplification on mountain slopes

Abstract Topographic amplification is widely invoked to explain strong shaking and slope failure in mountainous terrain, yet direct field observations remain limited. Here we analyze 24 regional earthquakes recorded by a four-station strong-motion array spanning a ridge crest, a...

Compositional Reuse of Semantic Change Relations in World Model Dynamics

Compositional generalization asks whether familiar structure can still be reused when familiar pieces appear in combinations absent during fitting. In world model dynamics, this becomes a question of whether directed effects among semantic changes can be recombined without learni...

Nonantipodal Semantic Change as a Planning Abstraction for World Model Latents

Planning with a world model depends not only on predictive accuracy but also on which distinctions remain available to downstream reasoning. The abstraction asks whether opposing semantic changes should be merged into one signed coordinate or preserved as separate directions unti...

Comparison of ligation security between monofilament polydioxanone and pseudomonofilament polyamide sutures in a standardized vascular model.

< 0.001). Leakage was eliminated only at 14 N for both materials, whereas high leakage rates occurred at lower force levels regardless of suture material. Time interval and suture material were not independently associated with leakage. These findings indicate that ligation secur...

Withdrawal Constrained Transfer for Revising Rollout Support in World Model Planning

Predictive world models organize candidate futures, yet execution experience can change which futures should retain deployment authority. This paper studies revision of a rollout admission rule rather than construction of a new planner or safety objective. Withdrawal Constrained...

Aluminum Cation-Catalyzed C2–H Activation and Enantioselective Michael Addition of Indoles

Abstract While C–H functionalization reactions are widely achieved using precious metal-based catalysts, such transformations are far less common for earth-abundant main-group metals. In this work, we demonstrate that prolinol-supported tetracoordinate aluminum cations can activa...

Oxygen‐Vacancy‐Engineered CoSnO 3 /rGO Nanocubes as High‐Performance Cathode Electrocatalysts for Advanced Vanadium Redox Flow Batteries

Oxygen vacancy‐engineered CoSnO 3 /reduced graphene oxide (CoSnO 3 /rGO) serves as a durable cathode electrocatalyst for vanadium redox flow batteries (VRFBs). Structural and spectroscopic analyses confirm the formation of defect‐rich amorphous CoSnO 3 uniformly integrated with a...

CO‐Tolerant Ethylene Glycol Oxidation on p–d Hybridized Platinum Ditelluride for Seawater Artificial Leaves

ABSTRACT Seawater‐based artificial leaves are fundamentally constrained by anodic surface poisoning and insufficient photovoltage for bias‐free reaction under complex electrolytes. Here we report a pH‐gradient photoelectrochemical–electrochemical (PEC–EC) system that couples phot...

Native Mass Spectrometry Reveals Ligand-Specific Conformational Heterogeneity of the β1-Adrenergic Receptor Using Nanobody Probes

Abstract G protein-coupled receptors (GPCRs) are central physiological signal transducers and represent a primary class of therapeutic targets. While emerging evidence highlights a critical link between ligand-induced receptor conformations and pharmacological outcomes, the struc...

Quantifying Cloud‐Fog‐Induced Reductions in Near‐Surface Solar Radiation Using the Reduction Ratio Method

Abstract Cloud‐fog formation substantially reduces near‐surface solar radiation and modulates land‐atmosphere interactions, but quantifying such reduction is limited by sparse mountain observations. Using a 1‐km geostationary satellite‐retrieved product, we apply the Reduction Ra...

Beyond technical fixes: vulnerable mobility and the affective governance of safety

Road safety interventions are increasingly guided by systemic models such as Vision Zero and the Safe System paradigm. Yet the institutional coherence presumed by these frameworks often breaks down in postcolonial governance environments. This article develops an epistemology of...

Multi-criteria life-cycle assessment framework for resilient and sustainable seismic retrofit planning of RC buildings

Achieving both seismic resilience and sustainability has emerged as a critical objective in contemporary building design and seismic retrofit practice. However, these goals often require substantial upfront investment, leading to trade-offs between initial disaster-prevention cos...

Typhoon‐Driven Near‐Surface Groundwater Dynamics Revealed by Ambient Noise in the Mountain Watershed

Abstract Near‐surface groundwater dynamics (NSGD) regulate water residence time and downstream water resources in mountain watersheds, yet whether a single extreme rainfall event can reorganize near‐surface storage remains unclear. Here, we examine typhoon‐driven NSGD using ambie...
