Gravitational lensing by a dark compact object in modified gravity and observational constraints from Einstein rings

European Physical Journal C: Particles and Fields
In this manuscript, we provide a comprehensive study of gravitational lensing by dark compact objects predicted by modified gravity (MOG) based on the scalar–vector–tensor action, with the aim of providing new insights into the nature of gravitational ...

ВЛИЯНИЕ ГРАВИТАЦИОННОГО ЛИНЗИРОВАНИЯ НА ФУНКЦИЮ СВЕТИМОСТИ КВАЗАРОВ

Odessa Astronomical Publications, 2011
The function of quasar distribution on apparent brightness is discussed. This function is found on base of suggestion that quasars, at least partly, are strong gravitational lensing images of the active nuclei of distant galaxies.

The Biased Interaction Game: A System Theoretic Approach to the Emergence of Inequality, Hierarchy, and the Implications for the Likelihood of Cooperation

Systems Research and Behavioral Science, EarlyView.
ABSTRACT The emergence of cooperation in natural selection has been successfully studied using game theory and, despite the underlying selfish nature of the evolutionary process, a spectrum of plausible mechanisms have been proposed to determine the conditions under which cooperative behaviour is likely to occur.

Experimental Investigations on the Impact of Operational Conditions on Bubble Dynamics and the Resulting Vibrations in Gas‐Stirred Ladles

steel research international, EarlyView.
This study applies sensitive vibration sensors to investigate gas bubble behavior in liquid metal during argon injection. Analysis of vibration signals provides insights into bubble evolution and the influence of gas flow and surface pressure. The results provide a basis for improved vibration‐based two‐phase flow models, enhancing accuracy in ...

Weak Gravitational Lensing in Fourth Order Gravity

, 2011
For a general class of analytic $f(R,R_{\alpha\beta}R^{\alpha\beta},R_{\alpha\beta\gamma\delta}R^{\alpha\beta\gamma\delta})$ we discuss the gravitational lensing in the Newtonian Limit of theory.

Galaxy–galaxy weak gravitational lensing in $f(R)$ gravity [PDF]

, 2017
We present an analysis of galaxy–galaxy weak gravitational lensing (GGL) in chameleon f(R) gravity – a leading candidate of non-standard gravity models. For the analysis, we have created mock galaxy catalogues based on dark matter haloes from two sets of

The Export and Financial Effects of Immigrant Team Composition in International New Ventures

Thunderbird International Business Review, EarlyView.
ABSTRACT Immigrant‐owned international new ventures (INVs) often partner with non‐immigrant entrepreneurs as co‐owners. Their mixed immigrant‐nonimmigrant teams could engender varied perspectives. But it is unclear whether such cognitive diversity improves their international strategy and performance.
