Nanocellulose-mediated conductive hydrogels with NIR photoresponse and fatigue resistance for multifunctional wearable sensors.

The rapid development of hydrogels has garnered significant attention in health monitoring and human motion sensing. However, the synthesis of multifunctional conductive hydrogels with excellent strain/pressure sensing and photoresponsiveness remains a challenge. Herein, the conductive hydrogels (BPTP) with excellent mechanical properties, fatigue resistance and photoresponsive behavior composed of polyacrylamide (PAM) matrix, 2,2,6,6-tetramethylpiperidin-1-yloxy-oxidized cellulose nanofibers (TOCNs) reinforcement and polydopamine-modified black phosphorus (BP@PDA) photosensitizer are prepared through a facile free-radical polymerization approach.

Acoustic emission characteristics of micro-discharges in initial pulsed PEO process on 60% SiC/Al composite.

The initial discharge process of pulsed plasma electrolytic oxidation (PEO) on the 60% SiC/2009 aluminum metal matrix composite (Al MMC) in silicate solution was monitored by acoustic emission (AE) technique. Parameters and correlations of AE signals on the Al MMC sample and under water were analyzed, and their generation mechanism was discussed. It was found that the peak amplitudes of AE signals and AE hits during the pulse time quickly increased with the increase of micro-discharge intensity, and the absolute energy of AE signals improved several orders of magnitude.

In situ monitoring of initial plasma electrolytic oxidation process on 60 vol. % SiCp/2009 aluminum matrix composite by sound and vibration measurement techniques.

The initial discharge process of plasma electrolytic oxidation (PEO) on the 60 vol. % SiCP/2009 aluminum matrix composite in silicate solution was in situ monitored by sound and vibration measurement techniques. The underwater sound, airborne sound, and sample vibration signals were detected in the initial 120 s of the PEO process, and their generation mechanism was discussed.

Expert System-Based Multiagent Deep Deterministic Policy Gradient for Swarm Robot Decision Making.

In this article, an expert system-based multiagent deep deterministic policy gradient (ESB-MADDPG) is proposed to realize the decision making for swarm robots. Multiagent deep deterministic policy gradient (MADDPG) is a multiagent reinforcement learning algorithm proposed to utilize a centralized critic within the actor-critic learning framework, which can reduce policy gradient variance. However, it is difficult to apply traditional MADDPG to swarm robots directly as it is time consuming during the path planning, rendering it necessary to propose a faster method to gather the trajectories.

Bionic Swarm Control Based on Second-Order Communication Topology.

In this article, we propose bionic swarm control based on second-order communication topology (SOCT) inspired by the migration of birds, which solves the difficulty in constructing communication topologies and high-computational complexity in controlling large-scale swarm systems. To realize bionic swarm control, there are three problems supposed to be solved. First, the adjacency matrix and the Laplacian matrix in traditional methods cannot be applied to SOCT directly, which should be redesigned.

The TLR4/NF-κB signaling pathway-mediated type 2 skewing of T helper cell in cough variant asthma was counteracted by ethanol extract of Anacyclus pyrethrum root.

Type 2 T helper (Th2) cells-mediated immune response plays a pivotal role in the pathogenesis of cough variant asthma (CVA), and this study aims to determine the effect and mechanism of ethanol extract of Anacyclus pyrethrum root (EEAP) on regulating Th2 response in CVA. Peripheral blood mononuclear cells (PBMCs) collected from patients with CVA, and naive CD4T cells induced by Th2-polarizing medium were administrated with EEAP. Interestingly, through conducting flow cytometry and enzyme linked immunosorbent assay method, we found that EEAP significantly alleviated Th2 skewing and increased Th1 response in these two kinds of cells.

Patternable Nanocellulose/TiCT Flexible Films with Tunable Photoresponsive and Electromagnetic Interference Shielding Performances.

Nanocellulose-mediated MXene composites have attracted widespread attention in the fields of sustainable energy, wearable sensors, and electromagnetic interference (EMI) shielding. However, the effects of different nanocelluloses on the multifunctional properties of nanocellulose/TiCT composites still need further exploration. Herein, we use three types of nanocelluloses, including bacterial cellulose (BC), cellulose nanocrystals (CNCs), and 2,2,6,6-tetramethylpiperidin-1-yloxy (TEMPO)-oxidized cellulose nanofibers (TOCNs), as intercalation to link TiCT nanosheets via a self-assembly process, improving the dispersibility, film-forming ability, mechanical properties, and multifunctional performances of nanocelluloses/TiCT hybrids through electrostatic forces and hydrogen bonding.

Degradation of 2,4-dichlorophenol by cathodic microarc plasma electrolysis: characteristics and mechanisms.

In this work, we used cathodic microarc plasma electrolysis (CMPE) to degrade 2,4-dichlorophenol (2,4-DCP) in simulated wastewater. By investigating and comparing the removal efficiencies and chemical oxygen demand (COD) during the degradation process, higher bath voltage and alkaline condition were considered as more suitable for the 2,4-DCP decomposition. Higher initial 2,4-DCP concentration was attributed to the increase in the utilisation of the energy input.

Haplotypic diversity and population genetic study of a population in Kashi region by 27 Y-chromosomal short tandem repeat loci.

Background: Y-chromosomal short tandem repeats (Y-STRs) have been certified to be the serviceable markers for some paternity cases in the last few years.

Methods: We presented the gene diversity, haplotypic diversity, and forensic statistical parameters of 340 unrelated Uighur males from Kashi region based on the 27 Y-STRs. Genomic DNA was extracted from bloodstain samples using the Chelex-100 method and amplified by Yfiler Plus PCR Amplification kit.

Coherence and decay of higher energy levels of a superconducting transmon qubit.

We present measurements of coherence and successive decay dynamics of higher energy levels of a superconducting transmon qubit. By applying consecutive π pulses for each sequential transition frequency, we excite the qubit from the ground state up to its fourth excited level and characterize the decay and coherence of each state. We find the decay to proceed mainly sequentially, with relaxation times in excess of 20  μs for all transitions.

Rotating-frame relaxation as a noise spectrum analyser of a superconducting qubit undergoing driven evolution.

Gate operations in a quantum information processor are generally realized by tailoring specific periods of free and driven evolution of a quantum system. Unwanted environmental noise, which may in principle be distinct during these two periods, acts to decohere the system and increase the gate error rate. Although there has been significant progress characterizing noise processes during free evolution, the corresponding driven-evolution case is more challenging as the noise being probed is also extant during the characterization protocol.
