Promoting public engagement through social media has always been a core issue in risk communication studies. Based on the Social Amplification of Risk Framework (SARF), this study conducts an online survey in China (N = 908) and constructs a moderated mediation model. Using bootstrapped moderated me...

The discrete ordinates (SN) method proposed by Carlson constitutes an angular discretization for neutron transport equation. Owing to its superior computational accuracy and efficiency compared to alternative numerical approaches, the SN method has been extensively adopted in neutron transport appli...

ABSTRACT To reveal the influence of dynamic load on the dynamic damage behavior of jointed rock masses, split Hopkinson pressure bar (SHPB) system was employed to test platy gabbro samples with joint angles of 15°, 30°, 45°, 65°, and 75° at an impact pressure of 0.1 MPa. It was found that the joint...

As an eco-efficient short-process manufacturing technique for aluminum alloys, twin-belt continuous casting and direct rolling (TBCCR) demonstrates significant production advantages. In this study, an Al-Fe-Si alloy system with different Fe-rich intermetallics (α-AlFe(Mn)Si and β-AlFe(Mn)Si) via TBC...

In this study, landslide risk assessment was conducted in the Renhe District, Panzhihua City, China. Firstly, based on 190 landslide points and 10 influencing factors, the landslide hazard was assessed using three models: random forest (RF), eXtreme Gradient Boosting (XGBoost), and Tabular Prior-dat...

In this work, the Nd and Sr elements were introduced into a special AA5083 (Al–Mg–Mn, 5XCT3, wCr + wTi = 0.3 wt%) alloy for modifying the β-Al3Mg2 precipitates, to investigate the influence of Sr and Nd on the mechanical properties and sensitization resistance. The results show that there is a signi...

Endovascular aneurysm repair requires lifelong imaging surveillance, typically with contrast-enhanced computed tomography imaging. This poses risks to patients with end-stage renal disease. Ferumoxytol, a superparamagnetic iron-based nanoparticle with minimal nephrotoxicity, has emerged as an altern...

Abstract Immune dysfunction in early pregnancy including overactivation of cytotoxic CD16+ NK cells and proinflammatory M1 macrophages at the maternal–fetal interface interferes with trophoblast invasion, spiral artery remodeling, and decidualization, potentially leading to miscarriage. Immunosuppre...

BackgroundLung function impairment, including preserved ratio impaired spirometry (PRISm) and airflow limitation (AL), is associated with increased risks of mortality and cardiovascular disease; however, the underlying biological mechanisms remain poorly understood. This study aimed to investigate t...
