Equivalência entre o princípio variacional de Maupertuis, a segunda lei de Newton e a geometria conforme

Revista Brasileira de Ensino de Física
As aplicações da geometria diferencial na física não estão restritas somente à teoria da relatividade geral. Esse artigo é dedicado a mostrar uma das diversas aplicações dos métodos geométricos a um conceito físico elementar e ao mesmo tempo profundo: a ...

Beachrock formation influenced by co‐seismic deformation and relative sea‐level changes during the Holocene near the Gulf of Saros, Türkiye (NE Aegean Sea)

Boreas, EarlyView.
This is the first proof of beachrock found on the nearshore of the Gulf of Saros. Beachrock generation was influenced by tectonic activity, geomorphological processes, and sedimentation. The Late Holocene beachrock deposits were altered by co‐seismic deformation.

SDFs from Unoriented Point Clouds using Neural Variational Heat Distances

Computer Graphics Forum, EarlyView.
We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from unoriented point clouds. We first compute a small time step of heat flow (middle) and then use its gradient directions to solve for a neural SDF (right). Abstract We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from ...

Mapping white matter tracts with SEEG electrodes

Epilepsia, EarlyView.
Abstract Objective Stereo‐electroencephalography (SEEG) is designed to record gray matter (GM) activity for epileptogenic zone localization. SEEG electrodes, however, traverse white matter (WM) pathways that connect regions involved in seizure networks and cognition.

Establishment and validation of a hair fall atlas for Chinese men based on trichoscopy

International Journal of Cosmetic Science, EarlyView.
A new hair fall atlas with 7 scales is established and validated and ready to publish as a new methodology. We observed good consistency between the dermatologists' grading (PCC >0.8), and a strong correlation shown between clinical scores and hair fall attributes based on image analysis (|p| > 0.8).
