Here, motivated by the principle of the high entropy-stabilized structure, high-entropy alloy-loaded porous TiO as an efficient and sintering-resistant catalyst for the light-driven reverse water gas‒shift reaction without external heating is synthesized. The optimized CoNiCuPdRu/TiO catalyst exhibits a long-term stability of 1000 h (1.

MATI: Multimodal Adaptive Tracking Integrator for Robust Visual Object Tracking.

Visual object tracking, pivotal for applications like earth observation and environmental monitoring, encounters challenges under adverse conditions such as low light and complex backgrounds. Traditional tracking technologies often falter, especially when tracking dynamic objects like aircraft amidst rapid movements and environmental disturbances. This study introduces an innovative adaptive multimodal image object-tracking model that harnesses the capabilities of multispectral image sensors, combining infrared and visible light imagery to significantly enhance tracking accuracy and robustness.

Formation of a Porous Crystalline MgAlO Overlayer on Metal Catalysts via Controlled Solid-State Reactions for High-temperature Stable Catalysis.

Catalyst deactivation by sintering and coking is a long-standing issue in metal-catalyzed harsh high-temperature hydrocarbon reactions. Ultrathin oxide coatings of metal nanocatalysts have recently appeared attractive to address this issue, while the porosity of the overlayer is difficult to control to preserve the accessibility of embedded metal nanoparticles, thus often leading to a large decrease in activity. Here, we report that a nanometer-thick alumina coating of MgAlO-supported metal catalysts followed by high-temperature reduction can transform a nonporous amorphous alumina overlayer into a porous MgAlO crystalline spinel structure with a pore size of 2-3 nm and weakened acidity.

A novel fluorescent turn on probe derived from Schiff base for highly selective and sensitive detection of Cu ion.

A fluorescent probe (L) of bis Schiff base secondary amine ligand was designed and synthesized from 2,6-pyridinedicarboxylic acid, ethylenediamine and salicylaldehyde by condensation and reduction reaction. Its structure was characterized by IR, UV-Vis, LIF, HNMR, C NMR, MS and elementary analysis. Investigation of binding test indicated that probe L could sensitively and selectively detect Cu ion with striking fluorescent signaling responses in anhydrous ethanol solvent.

Dehydrogenation of Ammonia Borane by Platinum-Nickel Dimers: Regulation of Heteroatom Interspace Boosts Bifunctional Synergetic Catalysis.

Regulation of the atom-atom interspaces of dual-atom catalysts is essential to optimize the dual-atom synergy to achieve high activity but remains challenging. Herein, we report an effective strategy to regulate the Pt -Ni interspace to achieve Pt Ni dimers and Pt +Ni heteronuclear dual-single-atom catalysts (HDSACs) by tailoring steric hindrance between metal precursors during synthesis. Spectroscopic characterization reveals obvious electron transfers in Pt Ni oxo dimers but not in Pt +Ni HDSAC.

Understanding the Relationship Between Mood Symptoms and Mobile App Engagement Among Patients With Breast Cancer Using Machine Learning: Case Study.

Background: Health interventions delivered via smart devices are increasingly being used to address mental health challenges associated with cancer treatment. Engagement with mobile interventions has been associated with treatment success; however, the relationship between mood and engagement among patients with cancer remains poorly understood. A reason for this is the lack of a data-driven process for analyzing mood and app engagement data for patients with cancer.

Cognitive bias modification for threat interpretations: using passive Mobile Sensing to detect intervention effects in daily life.

Background: Social anxiety disorder is associated with distinct mobility patterns (e.g., increased time spent at home compared to non-anxious individuals), but we know little about if these patterns change following interventions.

An analysis of the implementation effects of new paths and methods of occupational ethics education for medical students in higher vocational colleges.

Objective: To investigate the implementation effects of new paths and methods of occupational ethics education for medical students in higher vocational colleges.

Methods: A total of 668 students in higher vocational colleges were selected as the study subjects, and divided into traditional group (n=349) and innovative group (n=319) in accordance with their grades. The data pertaining to the students' views on the educational model of medical and occupational ethics, occupational passion, spirit of occupational risk, occupational ethics and codes, and doctor-patient rights and obligations and communication abilities and skills in the two groups were compared, so as to explore the influences of new paths and methods of occupational ethics education on the occupational ethics of medical students in higher vocational colleges.

The timing of continuous renal replacement therapy initiation in sepsis-associated acute kidney injury in the intensive care unit: the CRTSAKI Study (Continuous RRT Timing in Sepsis-associated AKI in ICU): study protocol for a multicentre, randomised controlled trial.

Introduction: Acute kidney injury (AKI) is one of the most common organ dysfunction in sepsis, and increases the risk of unfavourable outcomes. Renal replacement therapy (RRT) is the predominant treatment for sepsis-associated AKI (SAKI). However, to date, no prospective randomised study has adequately addressed whether initiating RRT earlier will attenuate renal injury and improve the outcome of sepsis.

Improved cancer biomarkers identification using network-constrained infinite latent feature selection.

Identifying biomarkers that are associated with different types of cancer is an important goal in the field of bioinformatics. Different researcher groups have analyzed the expression profiles of many genes and found some certain genetic patterns that can promote the improvement of targeted therapies, but the significance of some genes is still ambiguous. More reliable and effective biomarkers identification methods are then needed to detect candidate cancer-related genes.

Clinical Findings of COVID-19 Patients Admitted to Intensive Care Units in Guangdong Province, China: A Multicenter, Retrospective, Observational Study.

As the water-gas shift (WGS) reaction serves as a crucial industrial process, strategies for developing robust WGS catalysts are highly desiderated. Here we report the construction of stabilized bulk-nano interfaces to fabricate highly efficient copper-ceria catalyst for the WGS reaction. With an in-situ structural transformation, small CeO nanoparticles (2-3 nm) are stabilized on bulk Cu to form abundant CeO-Cu interfaces, which maintain well-dispersed under reaction conditions.
