A deconstruction of methods to derive one-point lensing statistics

open access: yesThe Open Journal of Astrophysics
Gravitational lensing is a crucial tool for exploring cosmic phenomena, providing insights into galaxy clustering, dark matter, and dark energy. Given the substantial computational demands of $N$-body simulations, approximate methods like $\texttt ...

Probing a regular non-minimal Einstein-Yang-Mills black hole with gravitational lensings

open access: yesPhysics Letters B, 2019
We investigate weak and strong deflection gravitational lensings of the regular black hole predicted by a non-minimal Einstein–Yang–Mills theory. We find that its weak deflection lensing is the same as a Reissner–Nordström black hole's.

Classroom boundaries and teacher agency: Challenges of implementing Ireland's new primary curriculum

open access: yesThe Curriculum Journal, EarlyView.
Abstract This article reports on a doctoral study examining teacher agency in one Irish primary school at a timely moment ahead of the implementation of the new Primary Curriculum Framework in September 2025. The framework embeds teacher agency as a central professional principle, yet findings from this study reveal a more cautious and bounded reality.

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

open access: yesEuropean 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 ...

GLASS: Generator for Large Scale Structure

open access: yesThe Open Journal of Astrophysics, 2023
We present GLASS, the Generator for Large Scale Structure, a new code for the simulation of galaxy surveys for cosmology, which iteratively builds a light cone with matter, galaxies, and weak gravitational lensing signals as a sequence of nested shells ...

Advanced Functional Materials for Marine Energy Utilization

open access: yesInterdisciplinary Materials, EarlyView.
Marine renewable energy is an important future clean energy supply. We construct and sort out the material system for marine energy capture and conversion, transmission, storage, and utilization for the first time. ABSTRACT Several features of marine energy, including large reserves, sustainable utilization, environmental friendliness, make it a ...

Weak lensing of large scale structure in the presence of screening

open access: yes, 2015
A number of alternatives to general relativity exhibit gravitational screening in the non-linear regime of structure formation. We describe a set of algorithms that can produce weak lensing maps of large scale structure in such theories and can be used ...

Sequelae of child maltreatment: Umbrella synthesis of 148 meta‐analyses on the mental health correlates

open access: yesJCPP Advances, EarlyView.
Our umbrella synthesis found strong, often equivalent, associations between child maltreatment and all examined mental health difficulties. Different types of maltreatment appear to have comparably negative effects on mental health. If replicated, these findings may cause us to reconsider conventional wisdom that suggests some forms of CM are less ...

The Role of Intellectual Virtues in the Practice of Humanistic Mental Health Counseling

open access: yesThe Journal of Humanistic Counseling, EarlyView.
ABSTRACT The function of intellectual virtues as a foundation for the development of excellence in the humanistic practice of clinical mental health counseling is explored. First, the unique characteristics of intellectual virtues are described. Second, 10 specific intellectual virtues are identified and briefly defined.
