Thermomechanical Properties of Natural Rubber/OPEFB Composites With Hybrid Latex–Starch Coupling Agent

ABSTRACT Natural rubber composites remain essential for industrial applications in Indonesia, particularly in tire manufacturing, where improved rigidity and strength are required. This study investigates the use of oil palm empty fruit bunch fiber as a sustainable filler to enha...

Comprehensive Spectroscopic Elucidation of Atomically Dispersed FeN 4 Active Sites of Fe‐N‐C Electrocatalysts

ABSTRACT To gain insights into single‐atom active sites of iron, nitrogen‐doped carbon (Fe‐N‐C), we performed comprehensive element‐specific spectroscopies including Fe K ‐edge X‐ray absorption, 57 Fe Mössbauer, and Fe Kβ 1,3 and valence‐to‐core (VtC) X‐ray emission spectroscopy...

Psychological profiles of readiness for advance care planning in super-aged Japan

Advance care planning (ACP) helps ensure that future medical care reflects individuals’ values and preferences. However, little is known about how multiple psychological characteristics combine to shape readiness for ACP, particularly in Japan. This study aimed to identify psycho...

Time-dependent queue length distribution in queues fed by K customers in a finite interval

Abstract We consider queueing models, where customers arrive according to a continuous-time binomial process on a finite interval. In this arrival process, a total of K customers arrive in the finite time interval [0, T ], where arrival times of those K customers are independent...

Supramolecular Protection–Deprotection for Switching Pore‐Surface Functionality in a Crystalline Porous Organic Salt

ABSTRACT The precise installation of highly interactive functional groups on pore surfaces remains a central challenge in crystalline porous materials since such groups often interfere with framework formation. In this study, supramolecular protection–deprotection was performed i...

Distribution and Time Trends of Refractive Errors in Japanese Spectacle Wearers

Purpose: This study aimed to estimate the distribution and temporal trends of refractive errors among spectacle wearers in Japan using a nationwide database of optical chain stores. Methods: Data from 4,525,689 individuals (53.0% women and 47.0% men; age range, 6-35 years) who pu...

Serum Agalactosyl IgG Predicts Hepatocellular Carcinoma and All‐Cause Mortality After SVR in Advanced Chronic Hepatitis C

BACKGROUND AND AIMS: Patients with chronic hepatitis C and advanced fibrosis remain at substantial risk of hepatocellular carcinoma (HCC) and non-liver-related death even after sustained virological response (SVR) to direct-acting antivirals (DAA). Serum agalactosyl IgG (agal-IgG...

Standardization of shotgun metagenomics parameters for pks-positive enterobacteria detection in human fecal samples: Receiver operating characteristic analysis using polymerase chain reaction as reference standard

Enterobacteria harboring the polyketide synthase ( pks ) island ( clbA – clbS ), which encodes colibactin ( pks⁺ enterobacteria), is a putative risk factor for colorectal cancer. Polymerase chain reaction (PCR) is the current standard for detection. Primer-independent shotgun met...

[ 18 F ] PSMA ‐1007 PET –Based Recurrence Site Distribution and Predictors of Metastatic Disease in Patients With Biochemical Recurrence of Prostate Cancer

ABSTRACT Objectives Prostate‐specific membrane antigen positron emission tomography (PSMA‐PET) is a sensitive imaging modality for detecting recurrent prostate cancer following definitive local therapy. However, evidence on 18 F‐labeled PSMA tracers in Japanese patients with bioc...

Humidity‐Guided In Situ Polymerization for Controlled Formation of Smooth, Oriented Covalent Organic Framework Films

Efficient, reliable preparation of high-quality films of covalent organic frameworks (COFs) is essential for fully exploring the potential of this class of porous crystalline compounds in, for example, sensing and catalysis. To this end, in situ polymerization on substrates offer...
