Close Binary Stars Modeled by Two Prolate Ellipsoids in Synchronous Rotation
The Astronomical Journal, 2023 The presence of tidal deformations in close binary stars has already been confirmed by astronomical observations. The present paper aims to simply address an astronomy problem, studying the relative movement of close binaries disturbed by their mutual ...

Udwadia–Kalaba Equation for Constrained Mechanical Systems: Formulation and Applications
Chinese Journal of Mechanical Engineering, 2018 There are many achievements in the field of analytical mechanics, such as Lagrange Equation, Hamilton’s Principle, Kane’s Equation. Compared to Newton–Euler mechanics, analytical mechanics have a wider range of applications and the formulation procedures

On analytical formulas for the Virial coefficients [PDF]
arXiv, 2022 In many fields of statistical physics, for instance in the study of the liquid-gas phase transition in finite nuclear matter, the Virial coefficients of the Fermi gas play a major role. In this note, we provide relations, sum rules, analytical formulas and numerical values for such coefficients.

Analytical Models for Valence Fermions in Isotropic Traps [PDF]
Phys.Lett.A235:305,1997, 1997 For isotropic confining Ioffe-Pritchard or TOP potentials, a valence fermion trapped with a closed core of other fermions can be described by an analytical effective one-particle model with a physical eigenspectrum. Related constructions exist for Paul and Penning traps. The analytical models arise from quantum-mechanical supersymmetry.

On the Origins of Hamilton’s Principle(s)
EncyclopediaThis entry first provides an overview of the historical, cultural and epistemological background that is key for Hamilton’s positions on mechanics. We consider the investigations on geometrical optics in the 17th and 18th centuries, Euler’s and Lagrange ...

Diphthamide synthesis is linked to the eEF2‐client chaperone machinery
FEBS Letters, EarlyView.The diphthamide modification of eukaryotic translation elongation factor 2 (eEF2) is important for accurate protein synthesis. We addressed the potential coordination of de novo eEF2 synthesis with simultaneous or subsequent diphthamide modification. Our work reveals that the co‐chaperones Hgh1 and Cpr7, which are known to support folding of nascent ...

A dinâmica de um elipsoide em rotação
Revista Brasileira de Ensino de FísicaUm fenômeno físico interessante que contraria nosso senso comum concerne à dinâmica do movimento de um elipsoide em rotação numa superfície não lisa. Um elipsoide em rotação é, por exemplo, um ovo cozido, girando numa mesa de superfície áspera.
