The conversion of into useful products such as methanol is a key strategy for abating climate change and our dependence on fossil fuels. Developing new catalysts fo…
Widely tunable dual acousto-optic interferometric device based on a hollow core fiber
Ricardo E. da Silva, Jonas H. Osório, Frédéric Gérôme +4
An all-fiber dual Mach-Zehnder interferometer (MZI) based on an acoustically modulated hollow-core fiber (HCF) is experimentally demonstrated for the first time. By attaching an ac…
Improving the energy resolution of photon counting Microwave Kinetic Inductance Detectors using principal component analysis
Jacob M. Miller, Nicholas Zobrist, Gerhard Ulbricht +1
We develop a photon energy measurement scheme for single photon counting Microwave Kinetic Inductance Detectors (MKIDs) that uses principal component analysis (PCA) to measure the…
Lorentz violation with an invariant minimum speed as foundation of the tachyonic inflation within a Machian scenario
Cláudio Nassif Cruz, Rodrigo Francisco dos Santos, A. C. Amaro de Faria
We show the relationship between the scalar kinematics potential of Symmetrical Special Relativity (SSR) and the ultra-referential of vacuum connected to an invariant minimum speed…
Towards Understanding the Dynamics of the First-Order Adversaries
Zhun Deng, Hangfeng He, Jiaoyang Huang +1
An acknowledged weakness of neural networks is their vulnerability to adversarial perturbations to the inputs. To improve the robustness of these models, one of the most popular de…
Lorentz violation with an invariant minimum speed as foundation of the Gravitational Bose Einstein Condensate of a Dark Energy Star
Claudio Nassif Cruz, Rodrigo Francisco dos Santos, A. C. Amaro de Faria
We aim to search for the connection between the spacetime with an invariant minimum speed so-called Symmetrical Special Relativity (SSR) with Lorentz violation and the Gravitationa…
CrimAnalyzer: Understanding Crime Patterns in São Paulo City
Garcia-Zanabria, Germain, Silveira +13
São Paulo is the largest city in South America, with high criminality rates. The number and type of crimes varies considerably around the city, assuming different patterns dependin…
Important role of projectile excitation in O+Ni and O+Al scattering at intermediate energies
V. A. B. Zagatto, F. Cappuzzello, J. Lubian +9
The elastic scattering angular distribution of the ONi system at MeV was measured in the range of the Rutherford cross section down to orders of magnitude…
Theoretical considerations about heavy-ion fusion in potential scattering
L. F. Canto, R. Donangelo, M. S. Hussein +3
We carefully compare the one-dimensional WKB barrier tunneling model, and the one-channel Schödinger equation with a complex optical potential calculation of heavy-ion fusion, for…
Nuclear processes in Astrophysics: Recent progress
V. Liccardo, M. Malheiro, M. S. Hussein +2
The origin of the elements is a fascinating question that scientists have been trying to answer for the last seven decades. The formation of light elements in the primordial univer…
