Circulating β-hydroxybutyrate levels are associated with major adverse clinical events in patients with acute myocardial infarction.

Background And Aims: Acute myocardial infarction is associated with high mortality, and effective biomarkers are required for the risk stratification. In cardiovascular diseases, circulating levels of ketone bodies (KB) such as β-hydroxybutyrate (β-OHB) and acetoacetate are altered. However, the relationship between circulating KB levels and major adverse clinical events (MACE) in patients with ST-elevation myocardial infarction (STEMI) is unknown.

Multimodal 2D Ferroelectric Transistor with Integrated Perception-and-Computing-in-Memory Functions for Reservoir Computing.

Emerging neuromorphic hardware promises energy-efficient computing by colocating multiple essential functions at the individual component level. The implementation is challenging due to mismatch between the characteristics of multifunctional devices and neural networks. Here, we demonstrate an artificial synapse based on a 2D α-phase indium selenide that exhibits integrated perception-and-computing-in-memory functions in a single-transistor setup, serving as a basic building block for reservoir computing.

Two Acceleration-Layer Configuration Amendment Schemes of Redundant Robot Arms Based on Zhang Neurodynamics Equivalency.

Two innovative acceleration-layer configuration amendment (CA) schemes are proposed to achieve the CA of constrained redundant robot arms. Specifically, by applying the Zhang neurodynamics equivalency (ZNE) method, an acceleration-layer CA performance indicator is derived theoretically. To obtain a unified-layer inequality constraint by transforming from angle-layer and velocity-layer constraints to acceleration-layer constraints, five theorems and three corollaries are theoretically derived and rigorously proved.

Inverse-free zeroing neural network for time-variant nonlinear optimization with manipulator applications.

In this paper, the problem of time-variant optimization subject to nonlinear equation constraint is studied. To solve the challenging problem, methods based on the neural networks, such as zeroing neural network and gradient neural network, are commonly adopted due to their performance on handling nonlinear problems. However, the traditional zeroing neural network algorithm requires computing the matrix inverse during the solving process, which is a complicated and time-consuming operation.

The mutation of Japanese encephalitis virus envelope protein residue 389 attenuates viral neuroinvasiveness.

The envelope (E) protein of the Japanese encephalitis virus (JEV) is a key protein for virus infection and adsorption of host cells, which determines the virulence of the virus and regulates the intensity of inflammatory response. The mutation of multiple aa residues in the E protein plays a critical role in the attenuated strain of JEV. This study demonstrated that the Asp to Gly, Ser, and His mutation of the E389 site, respectively, the replication ability of the viruses in cells was significantly reduced, and the viral neuroinvasiveness was attenuated to different degrees.
