Two–Integral Models with Almost Circular Orbits [PDF]
Symposium - International Astronomical Union, 1993 We present global dynamical models for bulge–disk systems. The phase–space structure is examined by means of two integral models. The models indicate that in the formation merger argument for ellipticals one cannot always assume that the maximum phase–space density occurs in the center of the system.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

The stability of orbit of a planet in the field of binary stars
Physical Sciences and Technology, 2020 In the paper, we consider the motion of a planet in the field of the binary stars in the theory of general relativity (GR), when all bodies have their own rotation. We consider that the third body moves in the plan of massive two bodies.

Multi-Step Control of Chaos in the Application of Earth-Moon Orbit Transfer [PDF]
Xibei Gongye Daxue Xuebao, 2018 A multi-step control of chaos method is proposed in this paper to reduce the flight time in the chaotic region of Earth-Moon low-energy orbit transfer.

Fuel optimal maneuvers of spacecraft about a circular orbit [PDF]
, 1982 Fuel optimal maneuvers of spacecraft relative to a body in circular orbit are investigated using a point mass model in which the magnitude of the thrust vector is bounded.

Conformal-thin-sandwich initial data for a single boosted or spinning black hole puncture
, 2003 Sequences of initial-data sets representing binary black holes in quasi-circular orbits have been used to calculate what may be interpreted as the innermost stable circular orbit. These sequences have been computed with two approaches.

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Effective one-body approach to general relativistic two-body dynamics
, 1998 We map the general relativistic two-body problem onto that of a test particle moving in an effective external metric. This effective-one-body approach defines, in a non-perturbative manner, the late dynamical evolution of a coalescing binary system of ...
