Phase Diagram, d-Wave Superconductivity, and Pseudogap of the t-t^{'}-J Model at Finite Temperature.

Recently, robust d-wave superconductive (SC) order has been unveiled in the ground state of the 2D t-t^{'}-J model-with both nearest-neighbor (t) and next-nearest-neighbor (t^{'}) hoppings-by density matrix renormalization group studies. However, there is currently a debate on whether the d-wave SC holds up strong on both t^{'}/t>0 and t^{'}/t<0 cases for the t-t^{'}-J model, which correspond to the electron- and hole-doped sides of the cuprate phase diagram, respectively. Here, we exploit state-of-the-art thermal tensor network approach to accurately obtain the phase diagram of the t-t^{'}-J model on cylinders with widths up to W=6 and down to low temperature as T/J≃0.

Robust ferromagnetism in wafer-scale FeGaTe above room-temperature.

The discovery of ferromagnetism in van der Waals (vdW) materials has enriched the understanding of two-dimensional (2D) magnetic orders and opened new avenues for fundamental physics research and next generation spintronics. However, achieving ferromagnetic order at room temperature, along with strong perpendicular magnetic anisotropy, remains a significant challenge. In this work, we report wafer-scale growth of vdW ferromagnet FeGaTe using molecular beam epitaxy.

Superconductivity with a maximum T of ≈6.

Determining the Optimal Age for Extracranial-Intracranial Bypass Surgery: A Post Hoc Analysis of the CMOSS Randomized Trial.

Background: Previous trials have failed to demonstrate the benefits of extracranial-intracranial (EC-IC) bypass surgery for patients with carotid or middle cerebral artery occlusion. However, little evidence has focused on the effect of age on prognosis. This study aimed to explore whether EC-IC bypass surgery can provide greater benefits than medical therapy alone in specific age groups.

Molecular Hydride Superconductor BiH with up to 91 K at 170 GPa.

In pursuit of high- hydride superconductors, the molecular hydrides have attracted less attention because the hydrogen quasimolecules are usually inactive for superconductivity. Here, we report on the successful synthesis of a novel bismuth hydride superconductor 2/-BiH at pressures around 170-180 GPa. Its structure comprises bismuth atoms and elongated hydrogen molecules with a H-H bond length of 0.

Genetic variation and clinical phenotype analysis of hypermethioninemia caused by MAT1A gene mutation: Case report.

Rationale: The high clinical heterogeneity of hypermethioninemia caused by MAT1A gene defects has resulted in a paucity of studies examining the association between clinical phenotypes, biochemical characteristics, and gene mutations in this patient group. Furthermore, the indications for therapeutic interventions in patients remain unclear. The objective of this study is to provide a foundation for clinical diagnosis, genetic counseling, and follow-up management of hypermethioninemia caused by MAT1A gene defects.

Signatures of ambient pressure superconductivity in thin film LaNiO.

Recently, the bilayer nickelate LaNiO has been discovered as a new superconductor with transition temperature T near 80 K under high pressure. Despite extensive theoretical and experimental work to understand the nature of its superconductivity, the requirement of extreme pressure restricts the use of many experimental probes and limits its application potential. Here, we present signatures of superconductivity in LaNiO thin films at ambient pressure, facilitated by the application of epitaxial compressive strain.

Pharmacokinetics, pharmacodynamics, safety, and immunogenicity of HLX14 versus reference denosumab in healthy males: A randomized phase I study.

Denosumab is a human IgG2 monoclonal antibody against receptor activator of nuclear factor kappa-B ligand (RANKL) for the treatment of osteoporosis and bone loss. HLX14 is a proposed biosimilar of denosumab. This randomized, parallel-group, two-part, phase I study aimed to compare the pharmacokinetics, pharmacodynamics, safety, and immunogenicity of HLX14 with reference denosumab in Chinese healthy adult male participants.

Intraperitoneal delivery of cannabidiol (CBD) and Δ-tetrahydocannabinol (THC) promotes papillomavirus infections in athymic nude mice.

We used our mouse papillomavirus (MmuPV1) model to test the hypothesis that two primary psychoactive ingredients of marijuana, Δ-tetrahydrocannabinol (THC) and cannabidiol (CBD), promote papillomavirus persistence in the oral mucosa of infected mice. We conducted intraperitoneal (ip) injections of a moderate dose (3 mg/kg) of either CBD and/or THC in both male and female athymic nude mice and followed the mice up to 20 weeks post-infection. These doses are comparable to what is estimated for human conventional cannabis consumption.

Probing the contact time of droplet impacts: From the Hertz collision to oscillation regimes.

Genome-Wide Association Study of Persistent Anal Human Papillomavirus Infection Among HIV-Positive Males in Taizhou, China: A Cohort Study.

The determinants of persistent human papillomavirus (HPV) infection remain largely unknown, and existing studies have predominantly focused on the female population. Individual genetic background may influence the persistence of HPV infection, we the evidence overall and among human immunodeficiency virus (HIV)-positive males are very limited. We conducted a genome-wide association study (GWAS) to identify single nucleotide polymorphisms (SNPs) associated with anal HPV persistence, based on a cohort designed to study the natural history of anal HPV infection among HIV-positive males in Taizhou, China from 2016 to 2022.

Unusual variants implicate uncommon genetic mechanisms for X-linked hypophosphatemic rickets.

X-linked hypophosphatemic rickets (XLH), the most common form of hereditary rickets, is characterized by renal phosphate wasting and abnormal vitamin D metabolism due to elevated circulating levels of the phosphatonin fibroblast growth factor 23 (FGF23). Dominant inactivating variants of the phosphate regulating endopeptidase homolog, X-linked (), gene are present in patients with XLH, and more than half of affected patients carry de novo variants. We report on 3 families in whom affected members had highly unusual pathogenic variants.

Prediction of high- superconductivity in HSX below megabar pressure.

The discovery of high critical temperature in cubic HS under high pressures attracts significant attention. Of particular recent interest is to search for superconductors stabilized at low pressure in order to approach practical applications. To examine the doping effect on the stability and superconductivity of HS, we construct HSX by replacing half of the S atoms with an X atom (X = Si, Ge, Sn, P, As, Sb, Te, Cl, Br and I).

Pressure aging: An effective process to liberate the power of high-pressure materials research.

High pressure can create extreme conditions that enable the formation of novel materials and the discovery of new phenomena. However, the ability to preserve the desirable characteristics of materials obtained under high pressure has remained an elusive challenge, as the pressure-induced changes are typically reversible, except for the pressure-induced chemical reactions such as polymerization of hydrocarbons. Here, we propose the concept of "pressure aging" (PA) that enables the permanent locking-in of high-pressure structures and their associated enhanced properties in functional materials.

Unlocking Cage-Confined Cations Molecular Dynamics toward High-T Perovskite Ferroelectrics.

Cage-confinement effect that imposes great constriction on the dynamic behaviors of guest molecules is an established platform for tailoring physical properties. Herein, the strategy of enhancing cage-confinement effect to control molecular motion has been probed for the first time to exploit new high-T ferroelectrics of 2D hybrid perovskites. By fine-tailoring of the confined cations inside the perovskite cavities, we have successfully obtained new homologous ferroelectrics of (BA)(MA)PbCl (1; BA=n-butylamine, MA=methylamine) and (BA)(EA)PbCl (2; EA=ethylamine).

Superconductivity in an infinite-layer nickelate superlattice.

Recent observations of superconductivity in infinite-layer nickelates offer insights into high-temperature superconductivity mechanisms. However, defects and dislocations in doped films complicate the realization of superconductivity, limiting current research to superconducting nickelate heterostructures. The lack of research on superconductivity in superlattices composed of ultrathin nickelates severely impedes not only the exploration of the interface effect on superconductivity, but also the utilization of heterostructure engineering for exploring higher superconducting temperature T.
