Bacterial Rhs proteins containing toxic domains are often secreted by type VI secretion systems (T6SSs) through unclear mechanisms. Here, we show that the T6SS Rhs-family effector TseI of Aeromonas dhakensis is subject to self-cleavage at both N- and C-terminus, releasing middle core two VgrG-interacting (which name VIRN VIRC). VIRC an endonuclease, immunity protein TsiI protects against toxicity direct interaction. Proteolytic release mediated, respectively, internal aspartic protease...
The type VI secretion system (T6SS) is a lethal microbial weapon that injects large needle-like structure carrying toxic effectors into recipient cells through physical penetration. How recipients respond to force and remains elusive. Here, we use series of effector mutants Vibrio cholerae determine how T6SS elicits response in Pseudomonas aeruginosa Escherichia coli. We show TseL, but no other or puncture, triggers the tit-for-tat P. H1-T6SS. Although E. coli sensitive all periplasmically...
Abstract To be able to produce ceramic bodies with complex shapes without interlayer delamination and warping through vat photopolymerization‐based 3D printing techniques, photosensitive slurries should studied prepare printed green sintered bodies. In this study, we developed dual curable acrylate–epoxide for digital light processing (DLP) printing. The curing process of the is a combination photo‐radical polymerization acrylate thermal cationic cyclo‐aliphatic epoxide. prepared by showed...
The reverse electrodialysis (RED) stack-harnessing salinity gradient power mainly consists of ion exchange membranes (IEMs). Among the various types IEMs used in RED stacks, pore-filling (PIEMs) have been considered promising to improve density stacks. compositions PIEMs affect electrical resistance and permselectivity PIEMs; however, their effect on performance large stacks not yet considered. In this study, with respect stack were adopted evaluate according size (electrode area: 5 × cm2...
Antimicrobial resistance (AMR) has become a serious public and economic threat. The rate of bacteria acquiring AMR surpasses the new antibiotics discovery, projecting more deadly infections in future. Pathogen Box is an open-source library drug-like compounds that can be screened for antibiotic activity. We have molecules against Vibrio cholerae, cholera-causing pathogen, successfully identified two compounds, MMV687807 MMV675968, inhibit growth. RNA-seq analyses V. cholerae after incubation...
Abstract In this study, spectroelectrochemical (SPE) studies to monitor the electrochromic properties of electrochemically synthesized sub‐10 nm sized Prussian blue (PB) nanostructures (NSs) are employed. At beginning dark coloured device, shifts reversibly between translucent and dark‐blue while applying an applied bias +1 −1 V with opposite polarization. Amine functionalized silicate sol‐gel matrix (SSG) is used as a solid support stabilizer for electrodepositing highly uniform PB NSs. The...
The progenitor system of Type Ia supernovae (SNe Ia) is expected to be a close binary carbon/oxygen white dwarf (WD) and non-degenerate star or another WD. Here, we present results from high-cadence monitoring observation SN 2021hpr in spiral galaxy, NGC 3147, constraints on the based its early multi-color light curve data. First, classify as normal long-term photometric spectroscopic More interestingly, found significant "early excess" over simple power-law $\sim t^{2}$ evolution. evolves...
FTN (Faster Than Nyquist) 전송 방식은 나이퀴스트 (Nyquist) 율보다 빠르게 신호를 전송할 수 있으나 필연적으로 ISI (Inter-Symbol Interference)가 발생하고 이로 인하여 송신 심볼 간 상관관계가 발생한다. 한편 터보류 채널 부호화 방식에서는 정보 프레임의 길이가 길어질수록 성능이 개선되나 길어짐에 따라 지연, 복호기의 복잡도 및 복호 지연이 증가하는 문제가 있다. 본 논문에서는 전송으로 발생한 상관관계를 활용하여 부호어 (codeword)들 간에 부여하고 이를 통하여 보다 큰 프레임을 사용하는 것과 같은 효과를 제공할 있는 기법을 제안한다. 제안하는 기법은 상관관계로 유사한 성능을 나타낼 뿐만 아니라 복호기에서는 다수의 구성 복호기 (constituent decoder)가 병렬로 연결된 구조를 갖고 있어 병렬 복호가 용이한 장점이 The performance of turbo-like codes highly depends on...
The electrodeposition of ZnO nanorods was performed on ITO glass. optimization two process parameters (solution temperature and growth time) has been studied in order to control the orientation, morphology, density, rate nanorods. structural optical properties were systematically investigated by using field-emission scanning electron microscopy, X-ray diffractometer, photoluminescence. Commonly, results property show that hexagonal with wurtzite crystal structures have a c-axis higher...
