Medium-Entropy LDH-Driven Electronic Coupling of MnO x for Preferential Oxidation of Formaldehyde

Abstract Preferential oxidation of formaldehyde (HCHO) in natural gas engine exhaust is pivotal to prevent NH3–SCR catalyst deactivation and inhibit highly toxic hydrogen cyanide (HCN) formation. Although manganese-based catalysts exhibit prominent activity for HCHO oxidation, co...

Exploring hydrogen production from plastic waste for urban transportation in Hong Kong and its environmental impact mitigation: integrating dynamic material flow analysis and life cycle assessment

Plastic waste to hydrogen technology offers a sustainable clean energy pathway while reducing landfill and incineration burdens. However, its feasibility as a feedstock for urban mobility decarbonization at the city scale remains largely unexplored. Hong Kong, as a densely popula...

Roles of molten salts in biomass pyrolysis: Heat and mass transfer, catalysis, and product regulation

Molten salt-assisted biomass pyrolysis is a promising way to fully utilize biomass resources for high value-added products. However, key aspects such as heat and mass transfer processes, catalytic pathway modulation and molten salt recovery have not yet been systematically review...

ScopeNovo: a De Novo Peptide Sequencing Method Using Spectrum-Spectrum Similarity to Refine the Prediction Accuracy

Abstract Motivation De novo peptide sequencing from tandem mass spectra is essential for characterizing unknown proteins, identifying novel post-translational modifications, and analyzing samples without reference databases. While recent deep learning models have improved the pre...

Metropolis-scale resilient and trustworthy traffic flow inference using multi-source data

Inferring network-wide traffic states from sparse observations with high accuracy and trustworthy uncertainty quantification is essential for intelligent transportation systems, yet it remains challenging due to the underdetermined nature of the problem, multifaceted disturbances...

Fault diagnosis of photovoltaic array under service-cycle degradation evolution via semi-supervised conditional domain adversarial network with dynamic label smoothing

The inevitable performance degradation of photovoltaic modules during long-term service induces a dynamic drift in their output feature distributions over time. However, existing fault diagnosis methods predominantly rely on static datasets acquired from undegraded arrays or thos...

Oxygen-vacancy-rich LDH sonosensitizers potentiate narrow-spectrum antibiotics via membrane-disruption strategy for mixed bacterial wound infections

Mixed bacterial infections, including Gram-positive and Gram-negative pathogens, remain a major global health concern. Achieving efficient treatment of synergistic polymicrobial infections stills a tremendous clinical challenge due to antibiotic permeability barriers and resistan...

From scrap to prime: Designing high-performance alloys from dirty feedstocks with machine learning

Producing alloys from recycled metals via secondary synthesis can markedly cut energy use, greenhouse-gas emissions, and dependence on scarce, strategically important elements relative to primary routes. The central obstacle is the feedstock itself: Scrap is chemically heterogene...

Searching for a Vanishing Fish: Development of an eDNA-Based Digital PCR Assay and Field Surveys for the Critically Endangered Chinese Bahaba

The critically endangered Chinese bahaba (Bahaba taipingensis) is difficult to monitor via conventional methods due to its low abundance and estuarine habitat. We developed a species-specific microfluidic digital PCR assay targeting the mitochondrial COI gene for environmental DN...

Control of axial dispersion in polymeric flows: Magnetic effect versus electro-osmotic effect

Since Taylor’s seminal work on the dispersion of soluble matter, the modelling and control of solute dispersion have received considerable attention. This study investigates the solute dispersion in polymer solutions driven by unsteady magnetohydrodynamic (MHD)-oscillatory electr...

From Representation to Enactment: The ABC Framework of the Translating Mind

Building on the third-wave extended-mind (EM) theory and radical enactivism, this article suggests a novel view on the translating mind. We build on the ABC framework, in which translation is not understood as the manipulation of static interlingual correspondences but an enacted...

Rational Construction of Indium-TiO2 Interfacial Composites for Boosting Urea Electrosynthesis

The electrocatalytic co-reduction of CO2 and nitrate to urea offers a sustainable route for carbon fixation, nitrogen waste recycling, and high-value chemical production. However, the rational design of efficient electrocatalysts with synergistic activation capability toward both...

Public Health and Optimal Trade Policy: The Role of Immigration

ABSTRACT We determine the optimal tariff in the presence of immigration and public health provision in a factor‐abundance‐driven trade model, and we prove two results. First, ceteris paribus , a higher value of immigrant output, a more efficient or cheaper public health service,...

Enteric-gated nano–probiotic living nanozyme for gut-directed redox–mitochondrial protection in cisplatin-induced acute kidney injury

Oral nano-biohybrid therapeutics provide opportunities for gut–organ axis intervention, but gastrointestinal transit often compromises both probiotic viability and nanozyme activity. Here, we developed CeO 2 @LP@EL, an enteric-gated nano–probiotic living nanozyme constructed by d...

Investigating disparities of supportive features: a comparative study between private and public long-term care homes of China

Purpose Long-term care homes (LCHs) are crucial in supporting older adults and promoting their health and quality of life. The supportive features in these homes often vary depending on funding sources, which directly impacts the well-being of residents in late life. This study a...

Multi-lemma representation of Mandarin noun-noun compounds in speech production: EEG evidence
