Photocatalytic CO2 conversion driven by solar energy is a highly promising approach in addressing rising atmospheric CO2 levels; however, its practical application remains limited…
Undulatory forcing of an intruder through granular media: effects of frequency and packing fraction
Douglas Daniel de Carvalho, Erick de Moraes Franklin
We investigate the motion amid grains of an intruder undergoing an imposed force that oscillates with a given frequency. For that, we made use of discrete numerical simulations whe…
Frankenstein in the Pipeline: Computational Epistemicide in Facial Recognition
Nina da Hora
While the eugenic roots of computer vision are well-documented in critical technology studies, less attention has been paid to the operational mechanisms through which this violenc…
Chaos-SSL: An Attention-Based Self-Supervised Learning Framework with Chaotic Transformation for Medical Image Classification
Joao Batista Florindo
Self-Supervised Learning (SSL) has emerged as a powerful paradigm to mitigate the reliance on large, annotated datasets, a common bottleneck in medical image analysis. However, sta…
Sleep-stage efficient classification using a lightweight self-supervised model
Eldiane Borges dos Santos Durães, João Batista Florindo
Accurate classification of sleep stages is crucial for diagnosing sleep disorders and automating this process can significantly enhance clinical assessments. This study aims to exp…
A multifractal-based masked auto-encoder: an application to medical images
Joao Batista Florindo, Viviane de Moura
Masked autoencoders (MAE) have shown great promise in medical image classification. However, the random masking strategy employed by traditional MAEs may overlook critical areas in…
Magnesium-graphene interphase boundaries created by high-pressure torsion enhance hydrogen storage kinetics:Mechanisms and significance of activation energy and frequency factor
Runchen Zhou, Payam Edalati, Anthony Alhayek +6
A strategy to overcome sluggish hydrogenation/dehydrogenation of magnesium is demonstrated by creating magnesium-graphene interphase boundaries via high-pressure torsion (HPT). HPT…
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…
Upgrade of the Trigger and Data Acquisition System for Continuous Imaging and Multi-Camera Operation in CYGNO
F. D. Amaro, R. Antonietti, E. Baracchini +41
The CYGNO experiment employs an optical readout to image particle interactions in a gaseous Time Projection Chamber (TPC), combining cameras and photomultiplier tubes (PMTs) to ach…

Gabriel Rabelo-Soares, Gojko Vujanovic, Giorgio Torrieri
The experimental observation of collective behaviour in proton-proton and proton-nucleus collisions poses a fundamental theoretical question regarding the proper characterization o…
Exploring Bounded Component Analysis Using an Norm Criterion
Renan D. B. Brotto, Kenji Nose-Filho, João M. T. Romano
In this paper we propose a new criterion for the Blind Source Separation (BSS) of antisparse bounded sources, based on the sum of the -norm of the sources. Based on th…
