Pre-processing of galaxies in cosmic filaments around AMASCFI clusters in the CFHTLS
, 2019 International audienceContext. Galaxy clusters and groups are thought to accrete material along the preferred direction of cosmic filaments. These structures have proven difficult to detect because their contrast is low, however, and only a few studies ...

Reconstructing Galaxy Cluster Mass Maps using Score-based Generative Modeling
The Open Journal of AstrophysicsWe present a novel approach to reconstruct gas and dark matter projected density maps of galaxy clusters using score-based generative modeling. Our diffusion model takes in mock SZ and X-ray images as conditional inputs, and generates realizations of corresponding gas and dark matter maps by sampling from a learned data posterior. We train and validate

The Manchester School, EarlyView.ABSTRACT This study considers mutual outsourcing firms in a vertically related market and examines their strategic adoption of environmental corporate social responsibility (ECSR) activities. We demonstrate that ECSR adoption reduces mutual outsourcing firms' profits, resulting in a prisoner's dilemma situation, but enhances welfare regardless of ...

Automation and Augmentation in Theological Perspective
Modern Theology, EarlyView.Abstract AI enables forms of automation that threaten unemployment and deskilling, eliminating important opportunities for the development of virtue. The concomitant loss of virtue and meaningful employment makes it a theological problem from the perspective of Catholic social teaching and theological anthropology.

The relative concentration of visible and dark matter in clusters of galaxies
, 2008 In general, the best evidence for the presence of dark matter is obtained when an additional mass component with distribution different from that of the visible matter is needed to explain the dynamical data.

Plant Biotechnology Journal, EarlyView.ABSTRACT Forward genetics has been instrumental in identifying genes underlying desirable traits, yet its application to polyploid plants, many of which are key agricultural crops, remains challenging due to their genomic complexity. Therefore, we developed BenthMap, a bulk segregant analysis platform for high‐throughput trait mapping and gene ...

Globular cluster systems and their implications of galaxy formation [PDF]
, 2008 In this thesis the spectroscopic and photometric results of the Galactic and extragalactic globular clusters are presented. And their implications on galaxy formation have been investigated.

Simulations All the Way Up! An Atheist's Response to the Fine‐Tuning Argument
Analytic Philosophy, EarlyView.ABSTRACT So the Fine‐tuning Argument goes, because it is so unlikely for the physical constants of the laws of nature to have taken the values that they in fact take, we should significantly raise our credence that God exists. Simulation Arguments argue that our world might be (or, in stronger versions, that it probably is) a mere computer simulation ...

How Many Worlds Could There Be? David Lewis and Advanced Modalizing
Analytic Philosophy, EarlyView.ABSTRACT Advanced modalizing, namely, possibilities and necessities concerning modal space itself, is problematic for a Lewis‐style analysis of modality. A popular solution, proposed by Divers, postulates explicit semantic clauses for a collapse of advanced modalizing, to the conclusion that all such matters are, if true in the first place, both ...
