IntroductionThis study examines whether specific lexicogrammatical features can reliably differentiate individuals with autism spectrum disorder (ASD) from non-ASD individuals. Classification models using logistic regression and deep neural networks (DNN) demonstrated high performance—80% accuracy,...

ABSTRACT Predatory interactions between large raptors and primates offer insights into evolutionary dynamics and ecological roles in tropical ecosystems. Harpy Eagles (Harpia harpyja), known for their size, are generally thought to pose minimal threat to humans, with many studies focusing on diet. H...

Recent cosmological observations have revealed growing tensions with the standard ΛCDM model, including indications of isotropic cosmic birefringence and deviations from w=−1 in the dark energy equation of state, as suggested by DESI and supernova measurements. In this paper, we point out that such...

The mobilization of the wealth of existing biodiversity data is fundamental for the development of large, dynamic and multifaceted datasets and their historical baselines. Biodiversity data need to be reliably and persistently linked to their sources in literary works and in databases. For this pur...

Myco-talpology is the study of the ecological relationship between moles and mushrooms. This discipline emerged from our 1976 discovery that the underground nests of talpid moles can be identified by the aboveground fruiting of the agarics Hebeloma sagarae, a Japanese sibling species of the European...

Understanding how spatial drought variability influences streamflow is critical for sustainable water management under changing climate conditions. This study developed a novel Combined Drought Index (CDI) and a method to assess spatial drought impacts on different flow components by integrating rem...

V1674 Her is one of the fastest novae, of which the very early phase is well observed, including optical rise to the peak over 10 mag. We present a full theoretical light-curve model of V1674 Her. Our 1.35 M _⊙ white dwarf (WD) model with the mass accretion rate of 1 × 10 ^−11 M _⊙ yr ^−1 explains o...

Little research has focused on using iron nitride as thermoseed particles in magnetic hyperthermia, although magnetite (Fe₃O₄) is commonly used for this purpose. In the present study, we focus on iron nitride, especially ε-Fe_2–3N....

Aluminum (Al) dissolves from soil at low pH and is absorbed by plants, inhibiting their growth. Since most of the Al absorbed by plants is present in the cell wall, it is thought that the binding of Al to cell wall polysaccharides alters the properties of the cell wall and inhibits cell elongation....

We present a material analysis method that links structure and process in dendritic growth using explainable machine learning approaches. We employed persistent homology (PH) to quantitatively characterize the morphology of dendritic microstructures. By using interpretable machine learning with ener...

This study presents a systematic investigation into non-Darcy fluid flow through rough-walled rock fractures to elucidate the complex interplay between fracture geometry, surface roughness, and hydraulic conditions. The research integrates high-resolution 3D finite-volume numerical simulations, solv...

Sign Language Recognition (SLR) plays a critical role in bridging communication gaps between the deaf and hearing communities. This research introduces GSR-Fusion, a deep multimodal fusion architecture that combines RGB-based, skeleton-based, and graph-based modalities to enhance gesture recognition...

Abstract The precipitation of energetic electrons from the outer radiation belt plays a crucial role in regulating their flux dynamics and influencing ionospheric properties. While theoretical and numerical studies, often based on near‐equatorial spacecraft measurements, are essential for assessing...

Abstract Background Nonocclusive mesenteric ischemia (NOMI) is a mesenteric arterial spasm and intestinal ischemia. This disease is a highly lethal disease because diagnosis and decision of appropriate treatments are often difficult. Operations cannot resolve the spasms and may worsen the situation....

Abstract Histamine exerts critical physiological roles by activating four receptor subtypes, each exhibiting a specific G protein preference. Among these, the histamine H4 receptor (H4R) modulates chemotaxis and interferon production through Gi protein activation, suggesting its therapeutic potentia...

Abstract Background The effectiveness of intraperitoneal chemotherapy using paclitaxel (i.p.‐PTX) in pancreatic ductal adenocarcinoma (PDAC) patients with peritoneal dissemination remains elusive. The aim of this study is to investigate the clinical outcome of patients treated with i.p.‐PTX combined...

In the conventional neuropsychological model, nonverbal visuospatial processing is predominantly handled by the right hemisphere, whereas verbal processing occurs in the left, with right-hand responses governed by the left motor cortex. Using intracranial EEG and MRI tractography, we investigated th...

Summary: Cell surface G protein-coupled receptors (GPCRs) are tightly regulated through constitutive and agonist-induced internalization. While the mechanisms of constitutive internalization remain elusive, agonist-induced internalization very often involves receptor phosphorylation by GPCR kinases...

Binary neutron-star (BNS) mergers are accompanied by multimessenger emissions, including gravitational wave (GW), neutrino, and electromagnetic signals. Some fraction of BNS mergers may result in a rapidly spinning magnetar as a remnant, which can enhance both the EM and neutrino emissions. In this...
