Observation of Yu-Shiba-Rusinov-like states at the edge of CrBr/NbSe heterostructure.

The hybrid ferromagnet-superconductor heterostructures have attracted extensive attention as they potentially host topological superconductivity. Relevant experimental signatures have recently been reported in CrBr/NbSe ferromagnet-superconductor heterostructure, but controversies remain. Here, we reinvestigate CrBr/NbSe by an ultralow temperature scanning tunneling microscope with higher spatial and energy resolutions.

Discovery of a long-ranged charge order with 1/4 Ge1-dimerization in an antiferromagnetic Kagome metal.

Exotic quantum states arise from the interplay of various degrees of freedom such as charge, spin, orbital, and lattice. Recently, a short-ranged charge order (CO) was discovered deep inside the antiferromagnetic phase of Kagome magnet FeGe, exhibiting close relationships with magnetism. Despite extensive investigations, the CO mechanism remains controversial, mainly because the short-ranged behavior hinders precise identification of CO superstructure.

JCAD deficiency attenuates activation of hepatic stellate cells and cholestatic fibrosis.

Background/aims: Cholestatic liver diseases including primary biliary cholangitis (PBC) are associated with active hepatic fibrogenesis, which ultimately progresses to cirrhosis. Activated hepatic stellate cells (HSCs) are the main fibrogenic effectors in response to cholangiocyte damage. JCAD regulates cell proliferation and malignant transformation in nonalcoholic steatoheaptitis-associated hepatocellular carcinoma (NASH-HCC).

Dimensionality-driven metal to Mott insulator transition in two-dimensional 1T-TaSe.

Two-dimensional materials represent a major frontier for research into exotic many-body quantum phenomena. In the extreme two-dimensional limit, electron-electron interaction often dominates over other electronic energy scales, leading to strongly correlated effects such as quantum spin liquid and unconventional superconductivity. The dominance is conventionally attributed to the lack of electron screening in the third dimension.

Charge order driven by multiple-Q spin fluctuations in heavily electron-doped iron selenide superconductors.

Intertwined spin and charge orders have been widely studied in high-temperature superconductors, since their fluctuations may facilitate electron pairing; however, they are rarely identified in heavily electron-doped iron selenides. Here, using scanning tunneling microscopy, we show that when the superconductivity of (LiFeOH)FeSe is suppressed by introducing Fe-site defects, a short-ranged checkerboard charge order emerges, propagating along the Fe-Fe directions with an approximately 2a period. It persists throughout the whole phase space tuned by Fe-site defect density, from a defect-pinned local pattern in optimally doped samples to an extended order in samples with lower T or non-superconducting.

Multiband Superconductivity with Sign-Preserving Order Parameter in Kagome Superconductor CsV_{3}Sb_{5}.

The superconductivity of a kagome superconductor CsV_{3}Sb_{5} is studied by scanning tunneling microscopy and spectroscopy at ultralow temperature with high resolution. Two kinds of superconducting gaps with multiple sets of coherent peaks and residual zero-energy density of states (DOS) are observed on both half-Cs and Sb surfaces, implying multiband superconductivity. In addition, in-gap states can be induced by magnetic impurities but not by nonmagnetic impurities, suggesting a sign-preserving or s-wave superconducting order parameter.

The Depression Anxiety Stress Scale-21 in Chinese Hospital Workers: Reliability, Latent Structure, and Measurement Invariance Across Genders.

The Depression Anxiety Stress Scale-21 (DASS-21) is an instrument in the assessment of mental health status. The current study recruited 1,532 Chinese hospital workers [74.4% female; mean age = 31.

Five-year follow-up observation of HIV prevalence in serodiscordant couples.

Objectives: To evaluate the rate of HIV seroconversion and the related risk factors among HIV discordant couples in Hubei Province, China.

Methods: HIV seroconversion rates and associated factors in discordant couples were identified during 2010-2012, based on existing data collected in serological and behavioral surveys between 2005 and 2007.

Results: At baseline, HIV transmission had occurred in 505 out of 1258 couples and the annual rate of HIV transmission was 6.

Gate-tunable phase transitions in thin flakes of 1T-TaS2.

The ability to tune material properties using gating by electric fields is at the heart of modern electronic technology. It is also a driving force behind recent advances in two-dimensional systems, such as the observation of gate electric-field-induced superconductivity and metal-insulator transitions. Here, we describe an ionic field-effect transistor (termed an iFET), in which gate-controlled Li ion intercalation modulates the material properties of layered crystals of 1T-TaS2.

Objective: To investigate the incidence of hepatotoxicity in acquired immunodeficiency syndrome (AIDS) patients on combined anti-retroviral therapy (cART) containing nevirapine (NVP) and to assess the risk factors and its impact on cART.

Methods: 330 AIDS patients from March 2003 to June 2008 at local county were enrolled and a retrospective study using Kaplan-meier survival and Multivariate logistic regression modeling was conducted.
