AbstractThe problem this paper addresses is that scientists have to take normatively charged decisions which can have a significant impact on individual members of the public or the public as a whole. And yet mechanisms to exercise democratic control over them are often absent. Given the normative nature of these choices, this is often perceived to be at odds with basic democratic principles.

A new transmission method for entangled photons by Leibniz University researchers could merge quantum and conventional internet over the same optical fibers, enhancing secure communications. Credit: SciTechDaily.comResearchers at Leibniz University Hannover have developed a technology for transmitting entangled photons through optical fibers, which could enable the integration of quantum and conventional internet, promising enhanced security and efficient use of existing infrastructure.

The Sculptor Galaxy (NGC 253), located in the Southern Hemisphere, far off the Galactic Plane, has a relatively high star-formation rate of about 7 M yr−1 and hosts a young and bright stellar population, including several super star clusters and supernova remnants. It is also the first galaxy, apart from the Milky Way Galaxy to be associated with two giant magnetar flares. As such, it is a potential host of pulsars and/or fast radio bursts in the nearby Universe.

We investigate the impact of public childcare provision on the incidence of severe child maltreatment. For identification, we exploit a reform that expanded early childcare in Germany, generating large temporal and spatial variation in childcare coverage at the county level.

High-Ti basalts are commonly believed to represent parental magmas leading to the formation of mafic-ultramafic layered intrusions, such as Late Permian Panzhihua and Hongge in the Emeishan Large Igneous Province (SW China). Consequently, elucidation of the crystallisation and crustal differentiation of high-Ti basalts is critical for our understanding of the petrogenesis of these layered intrusions and the associated oxide ore mineralisation.

We investigate the Lindblad equation in the context of boundary-driven magnetization transport in spin- chains. Our central question is whether the nonequilibrium steady state of the open system, including its buildup in time, can be described on the basis of the dynamics in the closed system. To this end, we rely on a previous study [Heitmann et al., Phys. Rev.

The sensitivity of the MeerKAT radio interferometer is an opportunity to probe deeper into the population of rare and faint extragalactic pulsars. The TRAPUM (TRAnsients and PUlsars with MeerKAT) collaboration has conducted a radio-domain search for accelerated pulsars and transients in the Small Magellanic Cloud (SMC).

We present the description and initial results of the TRAPUM (TRAnsients And PUlsars with MeerKAT) search for pulsars associated with supernova remnants (SNRs), pulsar wind nebulae and unidentified TeV emission. The list of sources to be targeted includes a large number of well-known candidate pulsar locations but also new candidate SNRs identified using a range of criteria.

AbstractWe develop low-order triangular virtual elements for linear Kirchhoff–Love shells from an engineering point of view. Flat element geometry is considered, which enables a direct shell discretization with no need for a curvilinear coordinate system or predefined initial mapping.

On the one hand, the X-ray and radio observations of Galactic pulsars revealed a likely neutron star (NS) maximum mass of (e.g. Antoniadis et al. 2013; Alsing, Silva & Berti 2018; Romani et al. 2022), consistent with the maximum mass inferred by the observations of NSs in gravitational-wave (GW) binaries (e.g. Margalit & Metzger 2017; Landry & Read 2021; Zhu et al. 2022a; Abbott et al. 2023a).
