Refill friction stir spot welding of AZ31 magnesium alloy sheets: metallurgical features, microstructure, texture and mechanical properties
Publication Type: Academic Journal
Source(s): Journal of Materials Research and Technology, Vol 23, Iss , Pp 3337-3350 (2023)
Abstract: In the present study, 1 mm-thick AZ31 magnesium alloy sheets were joined by refill friction stir spot welding. The metallurgical features, microstructure, texture and mechanical response of the spot-welded joints were investigated. The effect of weldin...
Effects of welding physical fields on the microstructure evolution during dynamic-stationary shoulder friction stir welding
Publication Type: Academic Journal
Source(s): Journal of Materials Research and Technology, Vol 23, Iss , Pp 3219-3231 (2023)
Abstract: Studying the physical fields in the friction stir welding (FSW) can reveal how they impact the microstructure of the joint, allowing one to develop more reliable joints. In this study, the Al–Cu dynamic-stationary shoulder friction stir welding (DSSFSW...
Effectiveness and safety of transcatheter aortic valve replacement in elderly people with severe aortic stenosis with different types of heart failure
Publication Type: Academic Journal
Source(s): BMC Cardiovascular Disorders, Vol 23, Iss 1, Pp 1-11 (2023)
Abstract: Abstract Background Impaired left ventricular function is an independent predictor of adverse clinical outcomes in patients with aortic stenosis. The aim of this study is to evaluate the short-term changes of echocardiographic parameters, New York Hear...
Effect of Hip Joint Center on Multi‐body Dynamics and Contact Mechanics of Hip Arthroplasty for Crowe IV Dysplasia

Abstract: Objective To investigate the hip joint forces, Von Mises stress, contact pressure and micro‐motion of hip prosthesis for developmental dysplasia of the hip (DDH) patients under different hip joint centers using musculoskeletal (MSK) multi‐body dynamics...
AdaFI-FCN: an adaptive feature integration fully convolutional network for predicting driver’s visual attention
Publication Type: Academic Journal
Source(s): Geo-spatial Information Science, Pp 1-17 (2022)
Abstract: Visual Attention Prediction (VAP) is widely applied in GIS research, such as navigation task identification and driver assistance systems. Previous studies commonly took color information to detect the visual saliency of natural scene images. However, ...
Biosoluble ceramic fiber reinforced poly(L-lactic acid) bone scaffold: degradation and bioactivity
Publication Type: Academic Journal
Source(s): npj Materials Degradation, Vol 6, Iss 1, Pp 1-10 (2022)
Abstract: Abstract Poly (l-lactic acid) (PLLA) exhibits great potential as a kind of scaffold material for bone defect repair because of its good biocompatibility and processability, while the too slow degradation rate hinders its further application. In this st...
Investigation of microstructure and properties in an aged ultra-high strength Al alloy and its friction stir welded joints
Publication Type: Academic Journal
Source(s): Journal of Materials Research and Technology, Vol 21, Iss , Pp 2338-2351 (2022)
Abstract: An Al–Zn–Mg-Sc-Zr alloy with high Zn was prepared to obtain ultra-high strength in the present study. The microstructure of the aged samples and the friction stir welding (FSW) joints were investigated by optical microscopy, electron backscatter diffra...
Eco-environmental quality assessment of the artificial oasis of Ningxia section of the Yellow River with the MRSEI approach
Publication Type: Academic Journal
Source(s): Frontiers in Environmental Science, Vol 10 (2023)
Abstract: Remote sensing ecological index (RSEI) has the advantages of rapid, repeatable and relatively accurate in regional eco-environment quality assessment. Due to the lack of consideration of the interaction of adjacent analysis units in RSEI calculation, t...
