First principles modeling of group-III acceptors and their potential lifetime-limiting effects in n-type 4H-SiC
José Coutinho
Accurate modeling of p-type dopants in 4H-SiC is essential for understanding the mechanisms governing doping efficiency and carrier transport. In this work, we revisit the electron…
The Regional Boundary Reconstruction Problem of the Initial State for Fractional Semilinear Systems
Khalid Zguaid, Fatima Zahrae El Alaoui, Delfim F. M. Torres
Observability is a fundamental concept in control theory. Its primary purpose is to look into whether it is possible to reconstruct the system's initial state using only the inform…
On Many-logic modal structures and information-based logics
Manuel Martins, Abílio Rodrigues, Marcelo Coniglio +1
This paper proposes an approach to information-based logics using many-logic modal structures (MLMS). These structures can express accessibility relations between worlds with diffe…
BioGraphletQA: Knowledge-Anchored Generation of Complex QA Datasets
Richard A. A. Jonker, Bárbara Maria Ribeiro de Abreu Martins, Sérgio Matos
This paper presents a principled and scalable framework for systematically generating complex Question Answering (QA) data. In the core of this framework is a graphlet-anchored gen…
Gravitational waves from warm inflation in the weak dissipative regime
Orlando Luongo, Tommaso Mengoni, Paulo M. Sá
Previous work on the gravitational-wave background generated in a two-scalar-field cosmological model, in which warm inflation and the dark sector are unified within a single frame…
Full-polarization millimeter wavelength variability of Sagittarius A* during the 2018 EHT campaign
Ezequiel Albentosa-Ruiz, Jasmin E. Washington, Nicola Marchili +272
Sagittarius A* (Srg A*), the supermassive black hole at the center of the Milky Way, provides a unique laboratory to study accretion dynamics and plasma processes near the event ho…
