Non-polarizing two-atom interaction potential in the liquid He-4 [PDF]
arXiv, 2001 A formula for potential U of the He-4--He-4 interaction in the liquid state is obtained by the direct electromagnetic computation as a function of the interatomic distance R. The potential decreases exponentially at large R. The further development and application of the result are discussed.

Spatially selective loading of an optical lattice by light-shift engineering using an auxiliary laser field [PDF]
, 2005 We report on a method of light-shift engineering where an auxiliary laser is used to tune the atomic transition frequency. The technique is used to selectively load a specific region of an optical lattice. The results are explained by calculating the differential light-shift of each hyperfine state.

The impact of frailty syndrome on skeletal muscle histology: preventive effects of exercise
FEBS Open Bio, EarlyView.Frailty syndrome exacerbates skeletal muscle degeneration via increased ECM deposition and myofiber loss. This study, using a murine model, demonstrates that endurance exercise attenuates these histopathological alterations, preserving muscle integrity. Findings support exercise as a viable strategy to counteract frailty‐induced musculoskeletal decline

Alvin Weinberg and the promotion of the technological fix [PDF]
, 2018 The term “technological fix”, coined by technologist/administrator Alvin Weinberg in 1965, vaunted engineering innovation as a generic tool for circumventing problems commonly conceived as social, political or cultural.

Numerical Analysis of Turbulent Mixed Convection in Vertical Annular Channel
Yuanzineng kexue jishu, 2023 Reactor cavity cooling system (RCCS) is a competitive residual heat removal scheme for small modular reactors. In this paper, the RCCS has been simplified to a scenario that ascending air flow is got heated in vertical annular channels and driven by ...

Physicists and the 1945 Decision to Drop the Bomb [PDF]
CERNCour.42N9:28739,2002, 2002 In 1943 fear that the German war machine might use atomic bombs was abating and among physicists another fear was taking its place - that of a postwar nuclear arms race with worldwide proliferation of nuclear weapons. Manhattan Project scientists and engineers began to discuss uses of nuclear energy in the postwar world.

Energy, work, entropy and heat balance in Marcus molecular junctions [PDF]
arXiv, 2020 We present a consistent theory of energy balance and conversion in a single-molecule junction with strong interactions between electrons on the molecular linker (dot) and phonons in the nuclear environment where the Marcus-type electron hopping processes predominate in the electron transport.

A Python package for fast GPU‐based proton pencil beam dose calculation
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Open‐source GPU‐based Monte Carlo (MC) proton dose calculation algorithms provide high speed and unparalleled accuracy but can be complex to integrate with new applications and remain slower than GPU‐based pencil beam (PB) methods, which sacrifice some physical accuracy for sub‐second plan calculation.
