Toward a Paradigm Shift in Low‐Temperature SCR Catalyst Design: Defect Engineering and Data‐Driven Integration

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work systematically reviews the key factors influencing the performance of low‐temperature NH3‐SCR. The mechanism and challenges of defect engineering strategies, such as oxygen vacancies, heteroatom doping, crystal facet exposure, and surface reconstruction, in controlling both activity and selectivity were analyzed.

Fabrication of a salt‐containing coacervated emulsion: Application in low‐salt mayonnaise with enhanced saltiness perception

Food Biomacromolecules, EarlyView.
Salt‐containing whey protein‐chitosan coacervates enabled stable emulsions with controlled sodium distribution, thereby enhancing perceived saltiness in low‐salt mayonnaise. Improved microstructure, rheology, and stability promoted sodium release during oral processing, offering an effective strategy for sodium reduction without compromising sensory ...

Beta Forecasting With Realized Beta Estimators and Machine Learning Algorithms

Journal of Forecasting, EarlyView.
ABSTRACT This paper applies machine learning algorithms to the modeling of realized betas for the purposes of forecasting stock systematic risk. Higher levels of beta forecast accuracy are demonstrated, relative to other studies in the literature. These improvements are also highly significant, both statistically and economically.

Machine Learning for Autism Spectrum Disorder Prediction: A Review of Data Augmentation and Feature Selection Techniques

Health Care Science, EarlyView.
Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterized by persistent difficulties in social communication, social interaction, and repetitive behaviors. Early diagnosis is often hindered by subjective clinical assessments and limited data availability.

Metabolic feature profiling and metabolic vulnerability in acute lymphoblastic leukemia

Interdisciplinary Medicine, EarlyView.
For the first time, our study develops a novel metabolic classification and subtyping program, metabolic reprogramming‐based classifier for acute lymphoblastic leukemia, using internal PDT‐ALL‐2016 and external cohorts, which dissects metabolic profiling, clinical outcome, and therapeutic vulnerability for precision metabolic intervention in ALL ...

Clustering of Cerebral Microbleeds in Cerebral Amyloid Angiopathy: A Flow Territory‐Based Analysis

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Cerebral microbleeds (CMBs) are a key imaging marker of cerebral amyloid angiopathy (CAA), but their individual spatial distribution and potential clustering remain poorly understood. Purpose This study assessed whether CMBs exhibit patient‐specific, flow territory‐based clustering in sporadic (sCAA) and Dutch‐type hereditary CAA (D‐
