AI-based framework to predict animal and pen feed intake in feedlot beef cattle
Alex S. C. Maia, John B. Hall, Hugo F. M. Milan +1
Advances in technology are transforming sustainable cattle farming practices, with electronic feeding systems generating big longitudinal datasets on individual animal feed intake,…
Pendulum Tracker -- SimuFísica: A Web-based Tool for Real-time Measurement of Oscillatory Motion
Marco P. M. de Souza, Juciane G. Maia, Lilian N. de Andrade
We present Pendulum Tracker, a computer vision-based application that enables real-time measurement of the oscillatory motion of a physical pendulum. Integrated into the educationa…
Electric Motor -- SimuFísica: an application for teaching electromagnetism
Marco P. M. de Souza, Sidnei P. Oliveira, Valdenice L. Luiz
In this work, we present the Electric Motor simulator, an application from the SimuFísica\textsuperscript{\textregistered} platform designed for classroom use. We briefly describe…
The Conservation of Mechanical Energy simulator -- SimuFísica
Marco P. M. de Souza, Cristiane M. de Oliveira, Rhakny P. P. Araújo
Currently, the benefits of using computer simulations in the school environment are widely recognized by educators. The encouragement to use these simulations in classrooms is supp…
When researchers pay to publish: Results from a survey on APCs in four countries
Osvaldo Gallardo, Matías Milia, André Luiz Appel +2
This paper provides an empirical overview of the impact and practices of paying Article Processing Charges (APCs) by four nationally categorized groups of researchers in Argentina,…
Patterning edge-like defects and tuning defective areas on the basal plane of ultra-large MoS monolayers toward hydrogen evolution reaction
Bianca Rocha Florindo, Leonardo H. Hasimoto, Nicolli de Freitas +11
The catalytic sites of MoS monolayers towards hydrogen evolution are well known to be vacancies and edge-like defects. However, it is still very challenging to control the po…
Eigenvalue estimates for a class of elliptic differential operators in divergence form on Riemannian manifolds isometrically immersed in Euclidean space
Marcio C. Araújo Filho, José N. V. Gomes
In this paper, we obtain eigenvalue estimates for a larger class of elliptic differential operators in divergence form on a bounded domain in a complete Riemannian manifold isometr…
Dynamic Stark shift in a Doppler-broadened four-wave mixing
M. P. M. de Souza, A. A. C. de Almeida, S. S. Vianna
This work presents a theoretical analysis of the Autler-Townes splitting pattern in the four-wave mixing signal generated in a three-level cascade Doppler-broadened system. We empl…
Inequalities for eigenvalues of fourth-order elliptic operators in divergence form on complete Riemannian manifolds
Marcio Costa Araújo Filho
We prove some inequalities of Payne-Pólya-Weinberger-Yang type for eigenvalues of fourth-order elliptic operators in weighted divergence form on complete Riemannian manifolds which…
Estimates of eigenvalues of an elliptic differential system in divergence form
Marcio C. Araújo Filho, José N. V. Gomes
In this paper, we compute universal estimates of eigenvalues of a coupled system of elliptic differential equations in divergence form on a bounded domain in Euclidean space. As an…
BGrowth: an efficient approach for the segmentation of vertebral compression fractures in magnetic resonance imaging
Jonathan S. Ramos, Carolina Y. V. Watanabe, Marcello H. Nogueira-Barbosa +1
Segmentation of medical images is a critical issue: several process of analysis and classification rely on this segmentation. With the growing number of people presenting back pain…
Amazon Forest Fires Between 2001 and 2006 and Birth Weight in Porto Velho
Taiane Schaedler Prass, Sílvia Regina Costa Lopes, José G. Dórea +2
Birth weight data (22,012 live-births) from a public hospital in Porto Velho (Amazon) was used in multiple statistical models to assess the effects of forest-fire smoke on human re…
Interference effect and Autler-Townes splitting in coherent blue light generated by four-wave mixing
M. P. Moreno, A. A. C. de Almeida, S. S. Vianna
An unexpected interference effect between four-wave mixing excitation routes in rubidium vapor is observed using a combination of a cw diode laser and a 1 GHz femtosecond pulse tra…
Electronic and optical properties of Mn impurities in ultra-thin ZnO nanowires: insights from density-functional theory
A. L. Rosa, L. L. Tacca, E. N. Lima +1
In this work we have employed density-functional theory with hybrid functionals to investigate the atomic and electronic structure of bare and hydrogenated Mn doped ZnO nanowires w…
Absolutely summing multipolynomials
T. Velanga
In this paper, we develop the theory of absolutely summing multipolynomials. Among other results, we generalize and unify previous works of G. Botelho and D. Pellegrino concerning…
Velocity-selective two-photon absorption induced by a diode laser in combination with a train of ultrashort pulses
Marco P. Moreno, Giovana T. Nogueira, Daniel Felinto +1
The two-photon transition in rubidium vapor is investigated by detecting the fluorescence from the state when the atomic system is excited by the combined act…
Multilinear mappings versus homogeneous polynomials and a multipolynomial polarization formula
T. Velanga
We show that (k,m)-linear mappings, introduced by I. Chernega and A. Zagorodnyuk in [3], are particular cases of polynomials. As corollaries, we expose some apparently overlooked p…
