A Curved Plate-Flattening Method to Construct the Membrane Strain Distribution

Journal of Marine Science and Engineering, 2023
The surface-flattening process has many applications in industries such as shipbuilding. Curved surfaces in the industry are usually formed from flat surfaces, so the target surface needs to be flattened to obtain its corresponding initial shape.

Welding deformation analysis based on improved equivalent strain method to cover external constraint during cooling stage

International Journal of Naval Architecture and Ocean Engineering, 2015
In the present study, external restraints imposed normal to the plate during the cooling stage were determined to be effective for reduction of the angular distortion of butt-welded or fillet-welded plate.

Photo-induced copper-catalyzed sequential 1,n-HAT enabling the formation of cyclobutanols

Nature Communications, 2021
Cyclobutanols are difficult structures to access given their inherent ring strain. Here, the authors present a method to form substituted cyclobutanols from a photocatalytic cascade reaction, proceeding via a 1,5- or 1,6-hydrogen atom transfer and ...

Cracking prediction at solid-tooth support interface during laser powder bed fusion additive manufacturing

Journal of Science: Advanced Materials and Devices, 2023
Cracking resulting from residual stress at the solid-tooth support interface frequently occurs in laser powder bed fusion (LPBF) metallic additive manufacturing, and thus it is critical to predict possible cracking and design the support to prevent it ...

Precision simulation and rapid prediction of complex parts formed by laser powder bed fusion based on multi-scale inherent strain method

Virtual and Physical Prototyping
Laser Powder Bed Fusion (LPBF) achieves layer-by-layer manufacturing of metal parts by melting metal powder using a high-energy laser beam. In response to the low accuracy and efficiency of the traditional inherent strain method in predicting residual ...

Neurocognitive, School‐Based, and Quality of Life Outcomes for Youth With Sickle Cell Disease and Thalassemia: A Scoping Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT The medical burdens of sickle cell disease (SCD) and transfusion‐dependent β‐thalassemia (TDT) are chronic and cumulative, even in children. Yet the effects expand beyond medications and healthcare visits due to their impacts on school attendance, academic performance, and peer engagement.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.
