Pandemic Vibrio parahaemolyticus has undergone rapid changes in both K- and O-antigens, making detection of outbreaks more difficult. In order to understand these changes, the genetic regions encoding antigens must be examined. cholerae vulnificus, O-antigen capsular polysaccharides are encoded a single region on large chromosome; similar arrangement pandemic V. would help explain serotype changes. However, previous reports "capsule" genes controversial. Therefore, we set out clarify...

Precise monolayer epitaxy is important for two-dimensional (2D) semiconductors toward future electronics. Here, we report a new self-limited approach, liquid phase edge (LPEE), precise-monolayer of transition-metal dichalcogenides. In this method, the solution contacts 2D grains only at edges, which confines grain edges and then precise can be achieved. High-temperature in situ imaging progress directly supports edge-contact mechanism. Typical dichalcogenide monolayers (MX2, M = Mo, W, Re; X...
Bilinear magnetoresistance (BMR), exhibiting a linear response to magnetic field or applied current, has garnered significant attention in recent research. While most previous works have focused on isotropic BMR, arising from band structure the spin Hall effect, we report strongly anisotropic BMR (ABMR) observed at KTaO3 Rashba interface, characterized by unique low-symmetry Fermi surface. For first time, successfully achieved regulation of ABMR through application gate voltage. Our...

Twenty-two Vibrio cholerae isolates, including some from "epidemic" (O1 and O139) "nonepidemic" serogroups, were characterized by pulsed-field gel electrophoresis (PFGE) multilocus sequence typing (MLST) using three housekeeping genes, gyrB, pgm, recA; data also obtained for the virulence-associated genes tcpA, ctxA, ctxB. Even with small number of loci used, MLST had better discriminatory ability than did PFGE. On analysis, there was clear clustering epidemic serogroups; much greater...
With the help of two-dimensional electron gas (2DEG) at LaAlO3–SrTiO3 interface, spin and charge currents can be interconverted. However, conversion efficiency has been strongly depressed by LaAlO3, which blocks transmission. It is therefore highly desired to explore 2DEGs sandwiched between ferromagnetic insulators that are transparent for magnons. By constructing epitaxial heterostructure with EuO, conducting current but insulating electric current, KTaO3, we successfully obtained 2DEGs,...
Exchange bias (EB) is highly desirable for widespread technologies. Generally, conventional exchange-bias heterojunctions require excessively large cooling fields sufficient fields, which are generated by pinned spins at the interface of ferromagnetic and antiferromagnetic layers. It crucial applicability to obtain considerable with minimum fields. Here, an exchange-bias-like effect reported in a double perovskite, Y2 NiIrO6 , shows long-range ferrimagnetic ordering below 192 K. displays...

Due to the strong interlayer coupling between multiple degrees of freedom, oxide heterostructures have demonstrated exotic properties that are not shown by their bulk counterparts. One most interesting is ferromagnetism at interface formed "nonferromagnetic" compounds. Here we report on interfacial ferromagnetic phase induced in superlattices consisting two paramagnetic oxides CaRuO3 (CRO) and LaNiO3 (LNO). By varying sublayer thickness superlattice period, demonstrate order has been...

ABSTRACT Mycobacteria include a large number of pathogens. Identification to species level is important for diagnoses and treatments. Here, we report the development Web-accessible database hsp65 locus sequences ( http://msis.mycobacteria.info ) from 149 out 150 Mycobacterium species/subspecies. This can serve as reference identifying species.
Magnetic proximity-induced magnetism in paramagnetic LaNiO3 (LNO) has spurred intensive investigations the past decade. However, no consensus been reached so far regarding magnetic order LNO layers relevant heterostructures. This paper reports a layered ferromagnetic structure for (111)-oriented LNO/LaMnO3 (LMO) superlattices. It is found that each period of superlattice consisted an insulating LNO-interfacial phase (five unit cells thickness, ∼1.1 nm), metallic LNO-inner phase, poorly...
