Asymptotic symmetries of Yang-Mills fields in Hamiltonian formulation
Journal of High Energy Physics, 2020 We investigate the asymptotic symmetry group of the free SU(N )-Yang-Mills theory using the Hamiltonian formalism. We closely follow the strategy of Henneaux and Troessaert who successfully applied the Hamiltonian formalism to the case of gravity and ...

Flow-enhanced priming of hESCs through H2B acetylation and chromatin decondensation
Stem Cell Research & Therapy, 2019 Background Distinct mechanical stimuli are known to manipulate the behaviors of embryonic stem cells (ESCs). Fundamental rationale of how ESCs respond to mechanical forces and the potential biological effects remain elusive.

Microgravity protein crystallization [PDF]
npj Microgravity, 2015 AbstractOver the past 20 years a variety of technological advances in X-ray crystallography have shortened the time required to determine the structures of large macromolecules (i.e., proteins and nucleic acids) from several years to several weeks or days.

Granular Convection in Microgravity [PDF]
Physical Review Letters, 2013 We investigate the role of gravity on convection in a dense granular shear flow. Using a microgravity modified Taylor-Couette shear cell under the conditions of parabolic flight microgravity, we demonstrate experimentally that secondary, convective-like flows in a sheared granular material are close to zero in microgravity and enhanced under high ...

Osteoclasts and Microgravity [PDF]
Life, 2020 Astronauts are at risk of losing 1.0 to 1.5% of their bone mass for every month they spend in space despite their adherence to high impact exercise training programs and dietary regimens designed to preserve their musculoskeletal system. This loss is the result of microgravity-related impairment of osteocyte and osteoblast function and the consequent ...
