Abstract Topic Esophageal Cancer: Esophageal Carcinogenesis Background Field cancerization in the upper aerodigestive tract is driven by alcohol, ALDH2 polymorphism, and TP53 mutation. However, animal models reflecting these factors are lacking. This study aims to clarify the com...

We demonstrate that quark confinement and a non-zero quantized mass gap naturally emerge from deterministic, exactly solvable chaotic dynamics. Crucially, the fluctuation spectrum is natively quantized by discrete Lyapunov exponents λL = lnK, yielding a universal logarithmic mass...

Hematopoietic stem cells (HSCs) constitute an organized hematopoietic system that undergoes age-related alterations, including increased platelet production and decreased erythropoiesis. The fundamental mechanisms driving these shifts remain incompletely understood. We used singl...

Immune checkpoint inhibitors (ICIs) have markedly improved survival in advanced non–small cell lung cancer (NSCLC), potentially modifying the prognostic impact of comorbid chronic obstructive pulmonary disease (COPD). We conducted a multicenter retrospective cohort study across f...

Abstract Electron and proton precipitation into the nightside ionosphere is a key process in magnetosphere–ionosphere coupling. Although auroral electron precipitation at –10 keV is traditionally considered the main driver of auroral emissions, recent studies show that keV electr...

The Evolutionary Paradox of Human Intelligence ー Why Intelligence Does Not Eliminate War
The dynamics described here parallel cultural narratives such as the Tower of Babel.In that story, a collectively constructed symbolic structure expands until it exceeds the constraints of the external world,after which the shared referential network collapses and language fragme...

Programming Backpropagation with Reverse Handlers for Arrows
We introduce a new programming language and its categorical semantics in order to design and implement neural networks within the framework of algebraic effects and handlers for arrows. Our language enables us to construct neural networks symbolically, in the same manner as algeb...

BACKGROUND: Cholangiolocarcinoma (CLC) is a rare liver cancer with ≥ 80% ductular configuration (DC). Given its rarity, its clinicopathological characteristics remain poorly understood, and its status as a distinct disease entity remains controversial. We conducted a nationwide m...

Chikungunya fever among Japanese travelers: monthly and yearly trends in imported cases, 2011–2023
Objectives: Chikungunya poses an increasing threat to people living in endemic areas and to travelers from non-endemic regions. This study descriptively characterized imported chikungunya cases in Japan and explored the relationship between local incidence in destination areas an...

BSFT-like action from cohomomorphism
Abstract By performing a field redefinition via a cohomomorphism on the Maurer-Cartan action of the A∞ algebra, we construct an action that reproduces the characteristic structure of boundary string field theory (BSFT), which we refer to as the BSFT-like action. We show that the...

Abstract This study explores advanced molecular breeding techniques for Aurantiochytrium limacinum , a eukaryotic microorganism valued for its industrial production of DHA and astaxanthin. We first employed the CRISPR-Cas9 system to simultaneously disrupt two genes: crtIBY , a mu...

Abstract Precise control of interfacial reactive hydrogen is crucial for improving the selectivity of proton-coupled electron transfer reactions in electrocatalysis. In the nitrate electroreduction to ammonia reaction, a fundamental trade-off is identified for copper (Cu)-based c...

Abstract Nickel nanofilms were prepared at an ethaline/toluene interface, which is a water-free deep eutectic solvent (DES)/oil (O) interface, where the absence of water enables a unique environment for interfacial redox chemistry. When NiCl42– in ethaline was contacted with deca...

ABSTRACT Solar‐driven interfacial evaporation (SDIE) offers a sustainable pathway for freshwater production, yet conventional hydrogel evaporators are hindered by high pore tortuosity, prolonged diffusion pathways, and interfacial salt accumulation that severely compromise long‐t...

Saturated backfills behind embedded cantilever walls deform through coupled hydro-mechanical processes that pseudo-static methods cannot capture. Three 40 g dynamic centrifuge tests are presented to isolate how the pre-seismic static state, set by wall flexural stiffness, togethe...

Auroral Belts as Magnetically Localized Reactors for Prebiotic Chemistry on Early Earth
Most models of prebiotic chemistry emphasize globally distributed or widely acting energy sources, including ultraviolet radiation, lightning, impacts, and energetic particles. However, spatially localized environments capable of repeatedly concentrating reactive chemistry may al...
