Scenario-based ESG scoring for sustainable financial investments using an advanced multi-facet fuzzy system

Sustainable financial investments are emerging as a multidimensional decision-making area that requires a holistic assessment of environmental, social, and governance (ESG) criteria. However, the literature demonstrates that the relative importance of each of these criteria on in...

Layer-by-Layer Electrode Design Integrating a Macroporous Carbon-Nanotube Skeleton for an Anion-Exchange Membrane Water Electrolyzer

Abstract Three-dimensional porous electrodes (anodes and cathodes) using only non-noble-metal electrocatalysts are important for enhancing the performance of anion-exchange membrane water electrolysis (AEMWE), contributing to reduced green-hydrogen production costs. This study de...

Lobular carcinoma as a spectrum: resolving the gray zone between morphology, E-cadherin, and CDH1

Invasive lobular carcinoma (ILC) is characterized by E-cadherin loss resulting from CDH1 inactivation, but discordance among morphology, immunohistochemistry (IHC), and molecular findings can complicate diagnosis. We integrated histology, IHC, DNA sequencing, and whole-transcript...

The nexus of sustainability: investigating energy transition, green technological innovations, and financial development in mitigating carbon emissions in BRICS

Purpose From the perspective of global environmental stability, the BRICS’ position as the world's leading carbon emitter poses a serious threat. Therefore, it is essential to develop a distinct model that enables policymakers to formulate robust mitigation strategies and support...

Dopant-Level Cobalt as an Electronic Promoter Stabilizes NiOOH for the Efficient Electrochemical Oxidation of 5-Hydroxymethylfurfural (HMF) to 2,5-Furandicarboxylic Acid (FDCA)

Abstract The electrochemical oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) is a promising route to biobased polymers using Ni-based hydroxide anodes. Although Co incorporation enhances performance, its mechanistic role in HMF oxidation remains un...

Geometry-engineered heat sinks for enhanced cooling performance in immersion-cooled servers

This study introduces a novel geometry-engineered dual-CPU heat sink framework for single-phase immersion liquid cooling (SPILC) servers, addressing the limitations of uniform designs that ignore the distinct thermal-hydraulic conditions of upstream and downstream CPUs. The origi...

Multifunctional Matrix‐Activated Electrodes Enabling Efficient Proton Transport and Durable Low‐Pt Operation for High‐Temperature Proton Exchange Membrane Fuel Cells

ABSTRACT Phosphoric acid (PA)‐related challenges, including PA loss, redistribution, and flooding, critically limit the performance and long‐term durability of high‐temperature proton exchange membrane fuel cells (HT‐PEMFCs) based on PA‐doped membrane electrode assemblies. Althou...

Drug Survival of Omalizumab and Factors Associated With Discontinuation in Chronic Urticaria

Importance Omalizumab is a recommended second-line therapy for chronic urticaria (CU), yet clinical evidence regarding long-term drug survival and determinants of discontinuation remains limited. Understanding drug survival patterns may inform clinical decision-making and patient...

Predicting clinical dementia rating scores from neuropsychological testing: a machine learning study in a large clinical cohort

To reduce variability of Clinical Dementia Rating (CDR) assessments taken from raters and informants, quantitative and reproducible approaches to support consistent interpretation are needed. We developed multiclass classification models of CDR global and regression models of CDR...

Age- and sex-adjusted genomic differences between Korean and Beat AML cohorts

Genomic profiling plays a central role in risk stratification and therapeutic decision-making in acute myeloid leukemia (AML), yet the clinical implications of population-specific genomic architectures remain incompletely defined. We conducted a prospective, multicenter study of...

Differential Diagnosis of Lung Cancer Using Artificial Intelligence-Based Extracellular Vesicle Analysis: A Pilot Study

Abstract In cancer diagnosis, liquid biopsy is a minimally invasive method, yet its diagnostic performance is constrained by insufficient sensitivity and restricted blood biomarkers. Therefore, the use of additional invasive methods is unavoidable to identify cancer-specific info...

Directionally Aligned, Defect-Suppressed Non-oxidatively Exfoliated Graphene Flakes for High EMI Shielding Performance

Abstract In this study, we report the development of high-performance electromagnetic interference (EMI) shielding composites incorporating directionally aligned non-oxidatively exfoliated graphene flakes (NOGF) within a polydimethylsiloxane (PDMS) matrix. The NOGF was synthesize...

Efficacy of Polyhexamethylene Biguanide Antibacterial Gel Coating of Orthopedic Implants in Infection Control and Immune Modulation
