PortBERT: Navigating the Depths of Portuguese Language Models
Raphael Scheible-Schmitt, Henry He, Armando B. Mendes
Transformer models dominate modern NLP, but efficient, language-specific models remain scarce. In Portuguese, most focus on scale or accuracy, often neglecting training and deploym…
Black hole shadows in nonminimally coupled Weyl connection gravity
Cláudio Gomes, Margarida Lima, Francisco S. N. Lobo +1
We study black hole shadows in nonminimally coupled Weyl connection gravity, a metric-affine extension of general relativity in which spacetime is described by a metric and a Weyl…
Analysis of the Metabolic Profile and Biological Activity of Hawthorn Species Twigs: Crataegus azarolus and Crataegus monogyna
Hiwa Sheikh Ahmed Qalatobzany, Kadhm Abdullah Muhammad, Djshwar Dhahir Lateef +4
All parts of the hawthorn tree (Crataegus spp.), including fruits, flowers, and leaves, have been used as a source of bioactive compounds. Thus, in this investigation, the twigs of…
On Scalar Cosmological Perturbations in Non-Minimally Coupled Weyl Connection Gravity
M. Lima, C. Gomes
We analyze a theory with non-minimal matter-curvature coupling, considering non-metricity properties with a Weyl connection. This model has the advantage of an extra force term whi…
Testing the Dark Universe through the Layzer-Irvine Equation
Cláudio Gomes
We review the cosmic generalisation of the virial theorem known as the Layzer-Irvine equation, also independently derived by Dmitriev and Zeldovich. This equation has been studied…
Weak Field Limit of the Nonminimally Coupled Weyl Connection Gravity
Cláudio Gomes
The true nature of gravity is a remarkable open problem in Gravitation. Theoretical and observational motivations open the avenue of alternative theories of gravity. One possibilit…
