Journal of High Energy Physics, 2021 We investigate the asymptotic symmetry group of a scalar field minimally-coupled to an abelian gauge field using the Hamiltonian formulation. This extends previous work by Henneaux and Troessaert on the pure electromagnetic case.

Experiment regarding magnetic fields with gravity
IET Quantum Communication, Volume 3, Issue 4, Page 218-228, December 2022., 2022 Abstract This experiment was designed to test the string theory as a physical reality. The ground‐based device placed the N poles of the magnets upwards, north, south, east, and west. Coil Ass'Y was placed between 2 N poles with bearing covers on the top and bottom.

Evaluation of Radiation Response in CoCrFeCuNi High-Entropy Alloys
Entropy, 2018 CoCrFeCuNi high-entropy alloys (HEAs) prepared by arc melting were irradiated with a 100 keV He+ ion beam. Volume swelling and hardening induced by irradiation were evaluated.

Adjuvant pharmacological strategies for the musculoskeletal system during long‐term space missions
British Journal of Clinical Pharmacology, EarlyView., 2023 Abstract Despite 2 h of daily exercise training, muscle wasting and bone loss are still present after 6‐month missions to the international space station. Some crew members lose bone much faster than others. In preparation for missions to the Moon and Mars, space agencies are therefore reviewing their countermeasure portfolios.

Consequences of simulated microgravity in neural stem cells: biological effects and metabolic response. [PDF]
, 2015 Objective: Microgravity was often shown to cause cell damage and impair cell cycle in a variety of biological systems. Since the effects on the neural system were poorly investigated, we aimed to gain insight into how biological processes such as cell ...

Understanding planet formation using microgravity experiments [PDF]
Nature Reviews Physics, 3, 405-421, 2021, 2023 In 2018, images were released of a planet being formed around the star PDS 70, offering a tantalizing glimpse into how planets come into being. However, many questions remain about how dust evolves into planets, and astrophysical observations are unable to provide all the answers.
