Shot Noise in a Metal Close to the Mott Transition.

SrIrO is a metallic complex oxide with unusual electronic and magnetic properties believed to originate from electron correlations due to its proximity to the Mott metal-insulator transition. However, the nature of its electronic state and the mechanism of metallic conduction remain poorly understood. We demonstrate that the shot noise produced by nanoscale SrIrO junctions is strongly suppressed, inconsistent with diffusive quasiparticle transport.

[Network Meta-analysis of Chinese patent medicines in treatment of idiopathic membranous nephropathy].

This study aimed to systematically evaluate the efficacy and safety of different Chinese patent medicines in the treatment of idiopathic membranous nephropathy. The relevant randomized controlled trial(RCT) was retrieved from PubMed, EMbase, Cochrane Library, CNKI, SinoMed, Wanfang, and VIP with the time interval from database inception to December 2022. The Cochrane risk of bias assessment tool was employed to evaluate the quality of the included RCT, and Stata 15.

Single skyrmion true random number generator using local dynamics and interaction between skyrmions.

Magnetic skyrmions are of great interest to both fundamental research and applications in post-von-Neumann computing devices. The successful implementation of skyrmionic devices requires functionalities of skyrmions with effective controls. Here we show that the local dynamics of skyrmions, in contrast to the global dynamics of a skyrmion as a whole, can be introduced to provide effective functionalities for versatile computing.

Micron-Scale Anomalous Hall Sensors Based on FePt Thin Films with a Large Hall Angle and near the Spin-Reorientation Transition.

In this work, we fabricate and characterize an energy-efficient anomalous Hall sensor based on soft-magnetic FePt thin films with a large anomalous Hall angle. By varying the composition of the FePt alloy, its layer thickness and interfacial materials, the magnetization is tuned to be near the spin transition between the perpendicular and in-plane reorientations. We performed magneto-transport and noise characterizations on anomalous Hall sensors with a small sensing area of 20 × 20 µm in the 180 to 350 K temperature range.

Ipsilateral femoral neck and intertrochanteric fractures with posterior dislocation of the hip: A report of two cases.

Traumatic hip dislocation usually occurs in young patients, with the increasing number of high-energy injuries, and 62-93% of reported adult traumatic hip dislocations were caused by high-speed motor vehicle crashes. However, ipsilateral femoral neck fractures and intertrochanteric fractures with posterior dislocation of the hip are extremely rare, and this injury poses a challenge to orthopaedic surgeons. Here, we report two cases of simultaneous ipsilateral femoral neck fracture, intertrochanteric fracture and posterior dislocation of the hip joint in young patients who were treated with proximal femoral locking compression plate (PFLCP).

Intervention with erythropoietin in sarcopenic patients with femoral intertrochanteric fracture and its potential effects on postoperative rehabilitation.

Aim: To explore the intervention with erythropoietin (EPO) in sarcopenic patients with femoral intertrochanteric fractures, and its potential effects on postoperative rehabilitation.

Methods: A total of 141 patients with femoral intertrochanteric fracture were selected from January 2018 to January 2019. Patients (aged ≥60 years) with indications for EPO use, but without significant medical history, were selected in the present study.

Low-Frequency Noise of Magnetic Sensors Based on the Anomalous Hall Effect in Fe-Pt Alloys.

We took advantage of the large anomalous Hall effect (AHE) in Fe-Pt ferromagnetic alloys and fabricated magnetic sensors for low-frequency applications. We characterized the low-frequency electronic noise and the field detectability of the FePt system with various thin film thicknesses and Fe concentrations. The noise source consisted of 1/ and Johnson noise.

Estimation of appendicular skeletal muscle: Development and validation of anthropometric prediction equations in Chinese patients with knee osteoarthritis.

Objective: To develop anthropometric prediction equations for estimating appendicular skeletal muscle (ASM) in Chinese knee osteoarthritis patients.

Methods: Subjects were divided into the model development group (MD group: 104 cases, 47 men and 57 women) and cross-validation group (CV group: 69 cases, 38 men and 31 women). Stepwise multiple linear regression analyses were undertaken in the MD group to identify the best equations.

[Analysis on related risk factors of hip fracture patient with sarcopenia].

Objective: To explore occurrence and risk factors of sarcopenia in patients with hip facture.

Methods: From May 2013 to January 2017, 187 patients with hip fractures were collected, including 99 males and 88 females aged from 50 to 95 years old with an average age of (77.40±10.

Quasicrystalline 30° twisted bilayer graphene as an incommensurate superlattice with strong interlayer coupling.

The interlayer coupling can be used to engineer the electronic structure of van der Waals heterostructures (superlattices) to obtain properties that are not possible in a single material. So far research in heterostructures has been focused on commensurate superlattices with a long-ranged Moiré period. Incommensurate heterostructures with rotational symmetry but not translational symmetry (in analogy to quasicrystals) are not only rare in nature, but also the interlayer interaction has often been assumed to be negligible due to the lack of phase coherence.

Meta-analysis of the effect of preoperative chemotherapy on Wilms' tumor.

Purpose: To evaluate the effect of preoperative chemotherapy on the event-free survival (EFS) and overall survival (OS) of Wilms' tumor in children, and to provide a basis for further improvement of clinical therapeutic effect and research level.

Methods: Relevant studies before July 2017 were retrieved from PubMed, EMBASE, Web of Science and other databases, and two evaluators were responsible independently for the studies' selection, data extraction and cross-checking according to the inclusion and exclusion criteria. EFS and OS of patients were assessed using hazard ratio (HR) and 95% confidence interval (CI).

Cysteine‑rich 61 RNA interference inhibits pathological angiogenesis via the phosphatidylinositol 3‑kinase/Akt‑vascular endothelial growth factor signaling pathway in endothelial cells.

Hypoxia is a key factor in the pathogenesis of angiogenesis, and cysteine‑rich 61 (CCN1), an angiogenic factor, is involved in the development of pathological angiogenesis. The aim of the present study was to investigate the mechanism of CCN1 RNA interference (RNAi)‑induced inhibition of hypoxia‑induced pathological angiogenesis in endothelial cells. Human umbilical vein endothelial cells (HUVECs) were cultured under hypoxic conditions in vitro.

Pseudo-Hydrogen Passivation: A Novel Way to Calculate Absolute Surface Energy of Zinc Blende (111)/(͞1 ͞1 ͞1) Surface.

Determining accurate absolute surface energies for polar surfaces of semiconductors has been a great challenge in decades. Here, we propose pseudo-hydrogen passivation to calculate them, using density functional theory approaches. By calculating the energy contribution from pseudo-hydrogen using either a pseudo molecule method or a tetrahedral cluster method, we obtained (111)/(111) surfaces energies of Si, GaP, GaAs, and ZnS with high self-consistency.

CCN1/Cyr61-PI3K/AKT signaling promotes retinal neovascularization in oxygen-induced retinopathy.

Retinal neovascularization (RNV) is a characteristic pathological finding of retinopathy of prematurity (ROP). Cysteine-rich 61 [Cyr61, also known as CCN family member 1 (CCN1)] has been reported to mediate angiogenesis. The aim of the present study was to investigate the mechanisms of CCN1/Cyr61-phosphoinositide 3-kinase (PI3K)/AKT signaling in ROP.

The mechanism of CCN1-enhanced retinal neovascularization in oxygen-induced retinopathy through PI3K/Akt-VEGF signaling pathway.

Background: CCN1 (also called Cyr 61) is an extracellular matrix signaling molecule that has been implicated in neovascularization through its interactions with several endothelial integrin receptors. The roles of vascular endothelial growth factor (VEGF) in angiogenesis are well described. The aim of this study was to investigate the signal transduction mechanism of CCN1-PI3K/Akt-VEGF in retinopathy of prematurity (ROP), and the effects of CCN1 knockdown on ROP.
