Report

Autor: de Souza, Lucas G. B., da Luz, M. G. E., Raposo, E. P., Curado, Evaldo M. F., Viswanathan, G. M.

In this contribution, we investigate how to correctly describe sums of independent and identically distributed random velocities in the theory of special relativity. We derive a one-dimensional probability distribution of velocities stable under rela

A Deep Learning-Based Approach for Mangrove Monitoring

Autor: de Souza, Lucas José Velôso, Zreik, Ingrid Valverde Reis, Salem-Sermanet, Adrien, Seghouani, Nacéra, Pourchier, Lionel

Mangroves are dynamic coastal ecosystems that are crucial to environmental health, economic stability, and climate resilience. The monitoring and preservation of mangroves are of global importance, with remote sensing technologies playing a pivotal r

Gravity-Induced Photon Interactions and Infrared Consistency in any Dimensions

Autor: Bittar, Pedro, Fichet, Sylvain, de Souza, Lucas

We compute the four-photon ($F^4$) operators generated by loops of charged particles of spin $0$, $\frac{1}{2}$, $1$ in the presence of gravity and in any spacetime dimension $d$. To this end, we expand the one-loop effective action via the heat kern

Gears and pulleys in non-Euclidean space forms

Autor: Cunha, Heleno S., de Souza, Lucas H. R., Prado, Sergio A. P.

In this article we study, in their non-Euclidean versions, two important mechanical systems that are very common in numerous devices. More precisely, we study the laws governing the movement of pulley and gear systems in spherical and hyperbolic geom

Spaces where all bijections are morphisms

Autor: de Souza, Lucas H. R.

Here we classify all topological spaces where all bijections to itself are homeomorphisms. As a consequence, we also classify all topological spaces where all maps to itself are continuous. Analogously, we classify all measurable spaces where all bij

Analysis of transient and intermittent flows using a multidimensional empirical mode decomposition

Autor: de Souza, Lucas F., Miotto, Renato F., Wolf, William R.

Modal decomposition techniques are important tools for the analysis of unsteady flows and, in order to provide meaningful insights with respect to coherent structures and their characteristic frequencies, the modes must possess a robust spatial suppo

Edge states and the $\eta$ invariant

Autor: Fresneda, Rodrigo, de Souza, Lucas, Vassilevich, Dmitri

Publikováno v: Phys. Lett. B844 (2023) 138098

We propose a relation between the $\eta$ invariant on a manifold with boundary, the $\eta$ invariants of edge states, and the $\eta$ invariant in an infinite volume limit. With the example of planar fermions with bag and chiral bag boundary condition
