The Pontifical messages of the World Day of Peace (1968–2024): An analytical introduction

open access: yesChurch, Communication and Culture
The end of World War II brought about an international consensus, the apex of which was the commitment to a dialogue-based solution to conflict that rejects the use of force. Shortly thereafter, however, war threatened the world once again.

Modular forms and elliptic curves over the field of fifth roots of unity [PDF]

open access: yes, 2010
Let F be the cyclotomic field of fifth roots of unity. We computationally investigate modularity of elliptic curves over F.Comment: Added appendix by Mark Watkins, who found an elliptic curve missing from our ...

Heredity for generalized power domination

open access: yes, 2016
In this paper, we study the behaviour of the generalized power domination number of a graph by small changes on the graph, namely edge and vertex deletion and edge contraction.

Reconfigurable Three‐Dimensional Superconducting Nanoarchitectures

open access: yesAdvanced Functional Materials, EarlyView.
3D superconducting nanostructures offer new possibilities for emergent physical phenomena. However, fabricating complex geometries remains challenging. Here 3D nanoprinting of complex 3D superconducting nanoarchitectures is established. As well as propagating superconducting vortices in 3D, anisotropic superconducting properties with geometric ...

Demonstration of an All‐Optical AND Gate Mediated by Photochromic Molecules

open access: yesAdvanced Functional Materials, EarlyView.
A logic AND gate that runs on photons is demonstrated. It relies on two spatially separated photochromic molecules that work in tandem. Abstract The realization of a photonic logic AND gate, i.e. a logic AND gate that runs on photons rather than electrons, and where all steps are controlled by light, is demonstrated. In a proof‐of‐principle experiment,

Generic limits of the Rhyparini with respect to the genus Termitodius Wasmann, 1894 (Coleoptera: Scarabaeidae: Aphodiinae) [PDF]

open access: yes, 2009
Three distinct tibial types are recognized within the Rhyparini (Scarabaeidae, Aphodiinae). Based on this, generic limits for the species of Termitodius Wasmann are reevaluated, with the Old World members being transferred to Termitodiellus Nakane.

Tuning the Dielectric Properties of Individual Clay Nanosheets by Interlayer Composition: Toward Nano‐Electret Materials

open access: yesAdvanced Functional Materials, EarlyView.
The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of

A System for Acquiring, Processing, and Rendering Panoramic Light Field Stills for Virtual Reality

open access: yes, 2018
We present a system for acquiring, processing, and rendering panoramic light field still photography for display in Virtual Reality (VR). We acquire spherical light field datasets with two novel light field camera rigs designed for portable and efficient
