Exchange of meteorites between the terrestrial planets and the Moon [PDF]

Modern astronomy: from the Early Universe to exoplanets and black holes. 2024. P. 904-909
The evolution of the orbits of bodies ejected from the Earth, Moon, Mercury and Mars was studied. At ejection velocities about 12-14 km/s, the fraction of bodies ejected from the Earth that fall back onto the Earth was about 0.15-0.25. The total number of bodies ejected from the Earth and delivered to the Earth and Venus probably did not differ much ...

Dependency of dynamical ejections of O stars on the masses of very young star clusters [PDF]

, 2015
Massive stars can be efficiently ejected from their birth clusters through encounters with other massive stars. We study how the dynamical ejection fraction of O star systems varies with the masses of very young star clusters, Mecl, by means of direct N -body calculations.

A Simple, Evidence-Based Approach to Help Guide Diagnosis of Heart Failure With Preserved Ejection Fraction

Circulation, 2018
Background: Diagnosis of heart failure with preserved ejection fraction (HFpEF) is challenging in euvolemic patients with dyspnea, and no evidence-based criteria are available.

Efficacy and Safety of Dapagliflozin in Heart Failure With Mildly Reduced or Preserved Ejection Fraction According to Age: The DELIVER Trial

Circulation: Heart Failure, 2022
Background: The prevalence of heart failure with mildly reduced or preserved ejection fraction markedly increases with age, with older individuals disproportionately facing excess risk for mortality and hospitalization.

Current Trends and Future Perspective for Cold Spray Metal‐Ceramic Composites

Advanced Engineering Materials, EarlyView.
The use of cold spray (CS) technology for creating cermet deposits, combining ceramic and metallic components, is advancing rapidly. Cermets offer excellent temperature handling and erosion resistance for diverse applications. This review outlines the current state of the art, focusing on the deposition dynamics and strategies to optimize the ...

Probabilities of collisions of bodies ejected from forming Earth with the terrestrial planets [PDF]

Icarus, 2025., v. 425, id. 116341 (24 p.)
The motion of bodies ejected from the Earth was studied, and the probabilities of collisions of such bodies with the present terrestrial planets were calculated. The dependences of these probabilities on velocities, angles and points of ejection of bodies were studied.

Two step ejection of massive stars and the issue of their formation in isolation [PDF]

, 2010
In this paper we investigate the combined effect of massive binary ejection from star clusters and a second acceleration of a massive star during a subsequent supernova explosion. We call this the "two-step-ejection" scenario. The main results are: i) Massive field stars produced via the two-step-ejection process can not in the vast majority of cases ...
