The nonlocal, local and mixed forms of the SPH method
(2021-12-15)
From its early days the SPH method has been criticised for its shortcomings namely tensile instability and consistency. Without thorough understanding of the method attempts were made to make the classical SPH method ...
GTC/CanariCam Deep Mid-infrared Imaging Survey of Northern Stars within 5 pc
(2021-12-15)
In this work we present the results of a direct imaging survey for brown dwarf companions around the nearest stars at the mid-infrared 10 micron range (λ c = 8.7 μm, Δλ = 1.1 μm) using the CanariCam instrument on the 10.4 ...
An Analog of the Feigin-Frenkel homomorphism for double loop algebras
(2021-12-15)
We prove the existence of a homomorphism of vertex algebras, from the vacuum Verma module over the loop algebra of an untwisted affine algebra, whose construction is analogous to that of the Feigin-Frenkel homomorphism ...
Efficacy and safety of the second in-hospital dose of tranexamic acid after receiving the prehospital dose: double-blind randomized controlled clinical trial in a level 1 trauma center
(2021-12-15)
Abstract: Background: Prehospital administration of tranexamic acid (TXA) to injured patients is increasing worldwide. However, optimal TXA dose and need of a second infusion on hospital arrival remain undetermined. We ...
Future Trends and Aging Analysis of Battery Energy Storage Systems for Electric Vehicles
(2021-12-14)
The increase of electric vehicles (EVs), environmental concerns, energy preservation, battery selection, and characteristics have demonstrated the headway of EV development. It is known that the battery units require special ...
Dietary management of gallstones: future possibilities
(2021-12-14)
Gallstones are common and affect up to 20% of adults overall. The prevalence is increasing with rising levels of obesity and aging populations.2 Although many people with gallstones are asymptomatic and the overall mortality ...
Polymer Architecture Effects on Poly(N,N‐Diethyl Acrylamide)‐b‐Poly(Ethylene Glycol)‐b‐Poly(N,N‐Diethyl Acrylamide) Thermoreversible Gels and Their Evaluation as a Healthcare Material
(2021-12-11)
Thermoreversible gels which transition between liquid‐like and solid‐like states when warmed have enabled significant novel healthcare technologies. Poly(N,N‐diethyl acrylamide) (PDEA) is a thermoresponsive polymer which ...
The Radioactive Nuclei 26Al and 60Fe in the Cosmos and in the Solar System
(2021-12-09)
The cosmic evolution of the chemical elements from the Big Bang to the present time is driven by nuclear fusion reactions inside stars and stellar explosions. A cycle of matter recurrently re-processes metal-enriched stellar ...
