Strong gravitational lensing with Gauss-Bonnet correction [PDF]

Journal of Cosmology and Astroparticle Physics, 2014
In this paper we investigate the strong gravitational lensing with Gauss-Bonnet gravity. By considering the logarithmic term for deflection angle, we obtain the deflection angle $\hat $ and corresponding parameters $\bar{a}$ and $\bar{b}$. Finally, by using the relations between the observables and lensing parameters, we estimate the observables such ...

A gamified formative question bank to enhance student learning and engagement in a foundational medical science course

Anatomical Sciences Education, EarlyView.
Abstract While gamified learning platforms show promise for engaging digital learners and promoting active learning, evidence of their effectiveness in predicting academic outcomes remains limited. This study examined how engagement patterns and incentives impact academic outcomes in a gamified environment to determine whether a formative question bank

Light Curves and Polarizations of Gravitationally Lensed Kilonovae

The Astrophysical Journal, 2023
Kilonovae are generally believed to originate from the ejecta of binary neutron stars (NSs) or black hole–NS mergers. Free neutrons might be retained in the outermost layer of the ejecta to produce a precursor via β decay.

Cosmic Equation of state from Strong Gravitational Lensing Systems [PDF]

, 2010
Accelerating expansion of the Universe is a great challenge for both physics and cosmology. In light of lacking the convincing theoretical explanation, an effective description of this phenomenon in terms of cosmic equation of state turns out useful ...

Consumer Emotions and Personality Traits in Augmented Reality

Journal of Consumer Behaviour, EarlyView.
ABSTRACT Augmented reality (AR) is an immersive and personalizable technology that has entered and expanded within the consumer market, yet the dynamics of valence, especially in relation to both positive and negative emotions and traits, remain underexplored.

Resolving the discrepancy between X-ray and gravitational lensing mass measurements for clusters of galaxies [PDF]

, 1997
We present a detailed comparison of mass measurements for clusters of galaxies using ASCA and ROSAT X-ray data and constraints from strong and weak gravitational lensing.

Foreground biases in strong gravitational lensing

Journal of Cosmology and Astroparticle Physics
Abstract Strong gravitational lensing is a competitive tool to probe the dark matter and energy content of the Universe. However, significant uncertainties can arise from the choice of lens model, and in particular the parameterisation of the line of sight.

Becoming inclusive: Developing pre‐service teachers' orientations towards their practice in Scotland

The Curriculum Journal, EarlyView.
Abstract This article presents findings, from a case study with a cohort of third‐year undergraduate pre‐service teachers (PSTs) in Scotland, regarding their ideas about inclusion and curricular justice, as they concurrently encountered practice and theory.

A Methodological Framework to Study Change in Team Cognition Under the Dynamical Hypothesis

Topics in Cognitive Science, EarlyView., 2023
Abstract The dynamical hypothesis claims that cognitive systems, such as teams, are dynamical systems (i.e., an interdependent collection of individuals and their technology that change together over time). Following this hypothesis, team researchers have adopted dynamical approaches to better understand the team cognitive processes and states that ...
