Asymmetric shape of distal phalanx of human finger improves precision grasping

open access: yesScientific Reports, 2021
In morphology field, the functions of an asymmetric-shaped distal phalanx in human finger have only been inferred. In this study, we used an engineering approach to empirically examine the effects of the shape of distal phalanx on the ability of ...

Similarity Classes in the Eight-Tetrahedron Longest-Edge Partition of a Regular Tetrahedron

open access: yesMathematics, 2023
A tetrahedron is called regular if its six edges are of equal length. It is clear that, for an initial regular tetrahedron R0, the iterative eight-tetrahedron longest-edge partition (8T-LE) of R0 produces an infinity sequence of tetrahedral meshes, τ0 ...

Fast Single-Mode Fiber Nonlinearity Monitoring: An Experimental Comparison Between Split-Step and Nonlinear Fourier Transform-Based Methods

open access: yesIEEE Photonics Journal, 2023
We experimentally investigate the problem of monitoring the Kerr-nonlinearity coefficient $\gamma$ from transmitted and received data for a single-mode fiber link of 1600 km length. We compare the accuracy and speed of three different approaches.
