Impact of Cladding Technology on Residual Stresses within the Renovation of High Pressure Die Casting Molds

Metals, 2022
Residual stresses significantly affect the overall lifetime of constructions. The main disadvantage of residual stresses is that their effect and magnitude is not evident at first sight and can only be reliably determined using experimental methods.

Monthly variation and spatial distribution of quadrant tropical cyclone size in the Western North Pacific

Atmospheric Science Letters, 2020
With the tropical cyclone (TC) size parameter defined as the radius of 17‐m·s−1 oceanic surface wind, 225 TC cases were recorded in the western North Pacific during 2000–2009 based on the QuikSCAT near‐surface wind vector database and the best‐track ...

Magnetic skyrmion annihilation by quantum mechanical tunneling

New Journal of Physics, 2020
Magnetic skyrmions are nano-scale magnetic states that could be used in various spintronics devices. A central issue is the mechanism and rate of various possible annihilation processes and the lifetime of metastable skyrmions.

Pionium lifetime corrections [PDF]

, 1998
Pionium lifetime corrections are evaluated in the frameworks of constrained Bethe-Salpeter equation and chiral perturbation theory. Corrections of order $O(\alpha)$ are calculated with respect to the conventional lowest-order formula, in which the strong

Pulmonary Dysfunction Is Associated With Sleep Study Abnormalities in Children With Sickle Cell Disease: A Multicenter Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Pulmonary dysfunction and sleep abnormalities are common in children with sickle cell disease (SCD) and are associated with worse clinical outcomes. Whether spirometry abnormalities are associated with polysomnography (PSG) findings remains unclear.
