Finite-Sized Orbiter’s Motion around the Natural Moons of Planets with Slow-Variable Eccentricity of Their Orbit in ER3BP

Mathematics, 2023
This article is devoted to the study of the stability of movement of a satellite of finite size around the natural satellites of the planets in the solar system, using the new concept of ER3BP with variable eccentricity.

Gravitational and axial anomalies for generalized Euclidean Taub-NUT metrics [PDF]

, 2004
The gravitational anomalies are investigated for generalized Euclidean Taub-NUT metrics which admit hidden symmetries analogous to the Runge-Lenz vector of the Kepler-type problem. In order to evaluate the axial anomalies, the index of the Dirac operator

Toward Sustainable Healthcare: Examining ESG‐Readiness in Austrian Regional State‐Owned Hospitals

Sustainable Development, EarlyView.
ABSTRACT Reporting on environmental, social, and governance (ESG) issues is now an essential part of responsible corporate governance, including in the healthcare sector. This study investigates the ESG reporting practices of Austrian regional state‐owned hospitals (rSOHs), contributing to the growing sustainability literature. Thirteen interviews with

Crisis, adaptation and recovery: A phase‐based exploration of Austrian non‐profit organizations during COVID‐19

Annals of Public and Cooperative Economics, EarlyView.
Abstract The COVID‐19 pandemic has severely impacted the external environment of social service non‐profit organizations (NPOs), resulting in diverse management challenges. Our study investigates how social service NPOs in Austria experienced these challenges and how they developed internal coping mechanisms.

Numerical Analysis for a Class of Variational Integrators

Mathematics
In this paper, we study a geometric framework for second-order differential systems arising in classical and relativistic mechanics. For this class of systems, we derive necessary and sufficient conditions for their Lagrangian description.

The Stark effect in the charge-dyon system

, 2003
The linear Stark effect in the MIC-Kepler problem describing the interaction of charged particle with Dirac's dyon is considered. It is shown that constant homogeneous electric field completely removes the degeneracy of the energy levels on azimuth ...

Politicized Framing of the Future: Encouraging Innovation in Mature Ecosystems in the Face of Asymmetric De Alio Entrants

Journal of Management Studies, EarlyView.
Abstract Hubs and participants of mature ecosystems increasingly compete with de alio entrants that are hubs of more innovative ecosystems. Prior research shows how these asymmetric de alio entrants frame to win over participants from mature ecosystems and suggests that hubs of these ecosystems should respond by encouraging innovation among ...

Stability and Fourier-series periodic solution in the binary stellar systems

, 2016
In this paper, we use the restricted three body problem in the binary stellar systems, taking photogravitational effects of both the stars. The aim of this study is to investigate the motion of the infinitesimal mass in the vicinity of the Lagrangian ...
