In this work, we investigate the existence of wormholes within the framework of Loop Quantum Cosmology, considering isotropic dark matter as the matter source. We examine three distinct density profiles and employ modified field equations along with

The impact of disk-locking on the stellar properties related to magnetic activity from the theoretical point of view is investigated. We use the ATON stellar evolution code to calculate theoretical values of convective turnover times ($\tau_{\rm c}$)

This paper presents near-infrared spectropolarimetric and velocimetric observations of the young planet-hosting T Tauri star PDS 70, collected with SPIRou at the 3.6m Canada-France-Hawaii Telescope from 2020 to 2024. Clear Zeeman signatures from magn

This work investigates whether phantom scalar fields combined with nonlinear electrodynamics (NED) can serve as sources for generalized Ellis-Bronnikov wormhole (GEB) spacetimes. This generalization of the Ellis-Bronnikov metric holds significant rel

We provide a methodology for decoupling the bulk gravitational field equations of braneworld black holes to suppress the bulk singularities. To achieve this, we apply a linear Minimal Geometric Deformation (MGD) with respect to a coupling constant \(

The NIFFTE fission Time Projection Chamber (fissionTPC) has been used to measure the $^{239}$Pu(n,f)/$^{235}$U(n,f) cross-section ratio for neutron-induced fission in the range of 0.1 - 100 MeV, with high precision. A white neutron source was provide

Background: Manual testing is vital for detecting issues missed by automated tests, but specifying accurate verifications is challenging. Aims: This study aims to explore the use of Large Language Models (LLMs) to produce verifications for manual tes

In the framework of Simpson-Visser, the search for field sources that produce black bounces in alternative gravity theories has remained unresolved. In this paper, the first in a series exploring sources for alternative theories of gravity, we identi

Continuous Integration (CI) encompasses a set of widely adopted practices that enhance software development. However, there are indications that developers may not adequately monitor CI practices. Hence, this paper explores developers' perceptions re
