An investigation on the electromagnetic wave absorbing performance and corrosion resistance of carbonyl iron powder/epoxy coatings modified by ferrosoferric oxide and basalt fibers.

With the development of science and technology, there is a great demand for electromagnetic wave absorbing materials for both military and civilian purposes. Among them, carbonyl iron powder (CIP) has attracted a lot of attention due to its mature production system and good electromagnetic wave loss capability. However, the application of CIP is limited due to poor impedance matching, poor corrosion resistance, and poor oxidation resistance.

Optimal control of discrete event systems under uncertain environment based on supervisory control theory and reinforcement learning.

Discrete event systems (DESs) are powerful abstract representations for large human-made physical systems in a wide variety of industries. Safety control issues on DESs have been extensively studied based on the logical specifications of the systems in various literature. However, when facing the DESs under uncertain environment which brings into the implicit specifications, the classical supervisory control approach may not be capable of achieving the performance.

Excellent Hole Mobility and Out-of-Plane Piezoelectricity in X-Penta-Graphene (X = Si or Ge) with Poisson's Ratio Inversion.

Recently, the application of two-dimensional (2D) piezoelectric materials has been seriously hindered because most of them possess only in-plane piezoelectricity but lack out-of-plane piezoelectricity. In this work, using first-principles calculation, by atomic substitution of penta-graphene (PG) with tiny out-of-plane piezoelectricity, we design and predict stable 2D X-PG (X = Si or Ge) semiconductors with excellent in-plane and out-of-plane piezoelectricity and extremely high in-plane hole mobility. Among them, Ge-PG exhibits better performance in all aspects with an in-plane strain piezoelectric coefficient = 8.

This study explores dietary intake correlations among women aged 30 yrs and above diagnosed with cervical cancer ( = 215), contrasted with women without ( = 860). These populations were selected from the 1999-2018 cycle of the National Health and Nutrition Examination Survey.

Oxymatrine ameliorated experimental colitis via mechanisms involving inflammatory DCs, gut microbiota and TLR/NF-κB pathway.

It is common knowledge that the crosstalk of gut microbiota (GM) and dendritic cells (DCs) are critical for the pathogenesis of inflammatory bowel disease (IBD). As a major bioactive constituent derived from the root of the Sophora flavescens, Oxymatrine (OMT) was used to treat IBD in China. However, it is still unknown whether OMT ameliorates IBD by regulating the crosstalk between DCs and GM.

Reliable predictability of patterns in decentralized discrete-event systems.

Predictability is an important property which is used to predict the failures which is not observable for the sensors straightly before they occur. In an automation system, in addition to the failure caused by a single event, there also exist pattern failures caused by event strings composed of multiple events. In order to prevent some local sites malfunction, the issue of reliable predictability of patterns is considered in this paper, where the prediction information may be distributed at physically separated sites.

Effect of Puerarin Regulated mTOR Signaling Pathway in Experimental Liver Injury.

It is known that excessive hepatocellular apoptosis is a typical characteristic of hepatic disease, and is regulated by the mammalian target of rapamycin (mTOR) signaling pathway. As the main active component of Kudzu () roots, which is frequently used to treat hepatic diseases, Puerarin (Pue) has been reported to alleviate and protect against hepatic injury. However, it is unclear whether Pue can inhibit mTOR signaling to prevent excessive apoptosis in the treatment of hepatic diseases.

Multielectron Effects in the Strong Field Sequential Ionization of Aligned CHI Molecules.

Strong field sequential ionization of symmetric-top CHI molecules is studied experimentally by using a combined method of femtosecond laser-induced impulsive alignment and time-of-flight mass spectrometry. Both alignment- and angular-dependent ion yields have been measured, and the sequential ionization of a multielectron has been discussed. It is found that the maximum ionization occurs when the polarization of probe laser is perpendicular to the internuclear axis of molecules, and the signal of fragment ion peaks at the polarization of the probe laser is parallel to the internuclear axis of molecules.

Highly Transparent, Conductive, and Bendable Ag Nanowire Electrodes with Enhanced Mechanical Stability Based on Polyelectrolyte Adhesive Layer.

In this paper, a highly transparent, conductive, and bendable Ag nanowire (AgNW)-based electrode with excellent mechanical stability was prepared through the introduction of an adhesive polyelectrolyte multilayer between AgNW networks and a polyethylene terephthalate (PET) substrate. The introduction of the adhesive layer was performed based on a peel-assembly-transfer procedure, and the adhesive polyelectrolyte greatly improved the mechanical stability of the AgNW transparent conductive films (TCFs) without obviously attenuating the morphology and optoelectrical properties of the AgNW networks. The as-prepared AgNW TCFs simultaneously possess high optical transparency, good conductivity, excellent flexibility, and remarkable mechanical stability.

Layer-by-layer strippable Ag multilayer films fabricated by modular assembly.

We have developed a new method to fabricate multilayer films, which uses prepared thin films as modular blocks and transfer as operation mode to build up multilayer structures. In order to distinguish it from the in situ fabrication manner, this method is called modular assembly in this study. On the basis of such concept, we have fabricated a multilayer film using the silver mirror film as the modular block and poly(lactic acid) as the transfer tool.

Reliable Decentralized Control of Fuzzy Discrete-Event Systems and a Test Algorithm.

A framework for decentralized control of fuzzy discrete-event systems (FDESs) has been recently presented to guarantee the achievement of a given specification under the joint control of all local fuzzy supervisors. As a continuation, this paper addresses the reliable decentralized control of FDESs in face of possible failures of some local fuzzy supervisors. Roughly speaking, for an FDES equipped with n local fuzzy supervisors, a decentralized supervisor is called k-reliable (1 ≤ k ≤ n) provided that the control performance will not be degraded even when n - k local fuzzy supervisors fail.
