The article present a research on probiotic nanozyme hydrogel, regulates vaginal microenvironment for Candida vaginitis therapy. It further discusses that molecular therapeutics damage normal cells and tissues of vagina, aggravating the imbalance of vaginal microbiota and increasing the recurrence; and reduced graphene oxide (rGO)]/Lactobacillus@hyaluronic acid (HA) designated as FeLab, has simultaneous anti–Candida albicans and vaginal microbiota-modulating activities.

In order to investigate the thermal runaway mechanism of 18650 lithium ion batteries and the related hazards, an experimental platform for lithium ion battery fire and explosion is designed and built. The effects of different arrangements, including vertical 2 × 2 and vertical 4 × 1, and initial pressure (96 kPa and 61 kPa) on lithium ion battery thermal runaway are studied in this paper. Compared with the results of thermal runaway characteristics with two arrangements, a higher explosion pressure, a larger mass loss, more O2 consumption and more CO and CO2 production are observed of vertical 2 × 2 batteries due to the larger contact area between batteries. The explosion pressure of vertical 4 × 1 batteries decreases gradually with thermal runaway propagation. For vertical 2 × 2 batteries, the explosion pressure of battery C, D is about twice as large as battery A. The intensity of chemical reaction is more violent under 96 kPa which cause a lower onset temperature and a shorter onset time than that under 61 kPa. The thermal runaway propagation hazard can be reduced by decreasing the contact area between batteries. The results could provide useful guidance for the safety of lithium ion battery transportation in civil aviation. [ABSTRACT FROM AUTHOR]

The article presents health and medicine research on integrated cascade nanozyme catalyzes in vivo ROS scavenging for anti-inflammatory therapy. Topics including integrated cascade nanozyme with a formulation of Pt@PCN222-Mn is developed to eliminate excessive reactive oxygen species (ROS); and method for constructing enzyme-like cascade systems but also illustrates their efficient therapeutic promise in the treatment of in vivo inflammatory bowel diseases.

Fast frequency hopping (FFH) is a useful anti-jamming method. Many diversity combining methods are used to combat partial-band interference in FFH systems, including linear and non-linear combining receivers. In fifth-generation scenarios, FFH technique may take an important role in OFDM mode. In early works, a nonlinear combining receiver in FFH/binary FSK system named division-combining receiver (DCR) was proposed. It was found that the random variables for decision in the DCR are F-distributed under partial-band noise jamming over additive white Gaussian noise channel, which could be used for performance analysis and the probability computation of bit error. In this Letter, the specific presentations of DCR and its F-distribution characteristics are investigated. Simulations show that DCR receiver has a light advantage among non-linear receivers.
