Titanium carbide and nitride MXenes are two-dimensional inorganic materials that exhibit noteworthy physical and chemical properties. These materials are considered for a variety o…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
Primordial Perturbations Including Second-Order Derivatives of the Inflationary Potential
Paulo Custodio, Cristian R. Ghezzi, Nadja S. Magalhae +1
In inflationary cosmology, the form of the potential is still an open problem. In this work, second-order effects of the inflationary potential are evaluated and related to the kno…
Few operators on Banach spaces
Leandro Candido
Using Ostaszewski's -principle, we construct a non-metrizable, locally compact, scattered space in which the operators on the Banach space exhibit…
Definition of multispectral camera system parameters to model the asteroid 2001 SN263
Gabriela de Carvalho Assis Goulart, Thiago Statella, Rafael Sfair
In 2012, Brazil began the studies to send its first deep space exploration mission, ASTER, which would be the first mission to orbit a triple asteroid system, 2001 SN263. We aim to…
On the weak separability of the space of Lipschitz functions
Leandro Candido, Marek Cuth, Benjamin Vejnar
We conjecture that whenever is a metric space of density at most continuum, then the space of Lipschitz functions is -separable. We prove the conjecture for several classe…
Off-shell pion properties: electromagnetic form factors and light-front wave functions
Jurandi Leão, J. Pacheco B. C. de Melo, T. Frederico +2
The off-shell pion electromagnetic form factors are explored with corresponding off-shell light-front wave functions modeled by constituent quark and anti-quark. We apply the Mande…
Classification and Clustering of Sentence-Level Embeddings of Scientific Articles Generated by Contrastive Learning
Gustavo Bartz Guedes, Ana Estela Antunes da Silva
Scientific articles are long text documents organized into sections, each describing aspects of the research. Analyzing scientific production has become progressively challenging d…
Evaluating Named Entity Recognition: A comparative analysis of mono- and multilingual transformer models on a novel Brazilian corporate earnings call transcripts dataset
Ramon Abilio, Guilherme Palermo Coelho, Ana Estela Antunes da Silva
Since 2018, when the Transformer architecture was introduced, Natural Language Processing has gained significant momentum with pre-trained Transformer-based models that can be fine…
Fully Atomistic Molecular Dynamics Investigation of the Simplest Model of Dry-Draw Fabrication of Carbon Nanotube Fibers
Luís F. V. Thomazini, Alexandre F. Fonseca
Macroscopic assemblies of carbon nanotubes (CNTs) are desirable materials because of the excellent CNT properties. Amongst the methods of production of these CNT materials, the dry…
The Design Strain Sensitivity of the Schenberg Spherical Resonant Antenna for Gravitational Waves
V. Liccardo, C. H. Lenzi, R. M. Marinho +4
The main purpose of this study is to review the Schenberg resonant antenna transfer function and to recalculate the antenna design strain sensitivity for gravitational waves. We co…
Magnetic flux penetration in nanoscale wedge-shaped superconducting thin films
L. B. L. G. Pinheiro, L. Jiang, E. A. Abbey +9
Thickness uniformity is regarded as an important parameter in designing thin film devices. However, some applications based on films with non-uniform thickness have recently emerge…
A new approach to the Lvov-Kaplansky conjecture through gradings
Ivan Gonzales Gargate, Thiago Castilho de Mello
In this paper we consider images of (ordinary) noncommutative polynomials on matrix algebras endowed with a graded structure. We give necessary and sufficient conditions to verify…
Critical parameter of the frog model on homogeneous trees with geometric lifetime
Sandro Gallo, Caio Pena
We consider the frog model with geometric lifetime (parameter ) on homogeneous trees of dimension . In 2002, \cite{alves2002-2} proved that there exists a critical lifetime…
Federated Learning Enables Big Data for Rare Cancer Boundary Detection
Sarthak Pati, Ujjwal Baid, Brandon Edwards +276
Although machine learning (ML) has shown promise in numerous domains, there are concerns about generalizability to out-of-sample data. This is currently addressed by centrally shar…
Mapping Long-Term Natural Orbits about Titania, a Satellite of Uranus
J. Xavier, A. B. Prado, S. M. Giuliatti Winter +1
Close polar and circular orbits are of great interest for the exploration of natural satellites. There are still no studies in the literature investigating orbits around Titania, t…
