Background: The non-enzyme autonomous DNA nanodevices have been developed to detect various analytes through the programmability of Watson-Crick base pairing. Nevertheless, by comparison with enzymatic biosensors, the usage of enzyme-free DNA networks to create biosensors for testing low amounts of targets is still subject to the finite number of cycles. Besides, these biosensors still require the incorporation of other amplification strategies to improve the sensitivity, which complicates the detection workflow and lacks of a uniform compatible system to respond to the target in one pot.

Due to similar clinical symptoms, it is challenging to make a definite diagnosis rapidly and accurately in the absence of microbiological tests. In the present study, an all-in-one real-time PCR assay was developed for the simultaneous detection of nucleic acids from SFGR, SFTSV and HTNV.

Objectives: The aim of this study was to investigate the clinical and molecular characteristics of Klebsiella pneumoniae infection from a tertiary general hospital in Wuhan, China.
Methods: From December 2019 to August 2022, 311 non-duplicate isolates of K. pneumoniae were collected from a tertiary hospital in Wuhan.
Single crystals ofRuGaandCoAl(= La and Pr) were grown using a Ga/Al self-flux method. An orthorhombic CaCoAl-type structure with space group(No.55) of them was identified by x-ray diffraction.

Using high-resolution electron energy loss spectroscopy, we report a systematic study of the temperature-dependent plasmon behaviors of 1T-TiSe_{2}. We unambiguously resolve the plasmon from phonon modes, revealing the existence of Landau damping to the plasmon at finite momentums, which does not support the plasmon softening picture for exciton condensation.

Recently, TFBs have been observed in several kagome metals, including FeSn, FeSn, CoSn, and YMnSn. Nonetheless, kagome materials that are both exfoliable and semiconducting are lacking, which seriously hinders their device applications.

The recent discovery of the polar metal LiOsO was therefore surprising [as discussed earlier in Y. Shi et al.
