Automation and Augmentation in Theological Perspective

open access: yesModern 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 Most Massive Early-type Galaxies Exhibit Tidal Features More Frequently in Lower-density Environments

open access: yesThe Astrophysical Journal
The most massive early-type galaxies (ETGs) are known to form through numerous galaxy mergers. Thus, it is intriguing to study whether their formation in low-density environments, where nearby companions are almost absent, is associated with mergers ...

Introduction: the (im)material spectrum of manuscript and print interaction☆

open access: yesRenaissance Studies, EarlyView.
Abstract This introductory essay to the special issue on Early Modern English Textual Cultures Between Manuscript and Print first outlines previous research into different kinds of interaction between manuscript and print. Examples of this interplay include, for instance, the transmission of text and images from one medium into another, the use of ...

Caxton's Afterlife in Manuscript (c.1475‐c.1500)

open access: yesRenaissance Studies, EarlyView.
Abstract At least thirty‐five manuscript copies of Caxton's prints have been found so far. This article explores the implications of such manuscript copies of Caxton's prints and, interrupting the linear history of the book, considers Caxton's appeal beyond print in manuscript.

Merger-driven Turbulence and Coherent Transport in the Intracluster Medium

open access: yesThe Astrophysical Journal
The distribution of metals and temperature in the intracluster medium (ICM) provides key insights into galaxy cluster evolution, revealing information about chemical enrichment and heating and cooling processes, respectively.

Quasar evolution via galaxy mergers

open access: yesThe Astrophysical Journal, 1990
The expected evolution of quasars is calculated using the dynamics of merging galaxies and the assumption that the birth rate of quasars is proportional to the rate of mergers. The merger rate is described using a modification of the Press-Schechter theory. As a specific model, the luminosity of a quasar is assumed to be proportional to its host galaxy'

Cerebrovascular pulsatility following long duration spaceflight is associated with changes in pulse pressure and carotid artery stiffness

open access: yesExperimental Physiology, EarlyView.
Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.
