Anguilliform Locomotion across a Natural Range of Swimming Speeds

Fluids, 2021
Eel-like fish can exhibit efficient swimming with comparatively low metabolic cost by utilizing sub-ambient pressure areas in the trough of body waves to generate thrust, effectively pulling themselves through the surrounding water.

The existence of superluminal particles is consistent with the kinematics of Einstein's special theory of relativity

, 2013
Within an axiomatic framework of kinematics, we prove that the existence of faster than light particles is logically independent of Einstein's special theory of relativity.

Decoding intentions from movement kinematics

Scientific Reports, 2016
How do we understand the intentions of other people? There has been a longstanding controversy over whether it is possible to understand others’ intentions by simply observing their movements.

Color-kinematics duality for QCD amplitudes [PDF]

, 2015
A bstractWe show that color-kinematics duality is present in tree-level amplitudes of quantum chromodynamics with massive flavored quarks. Starting with the color structure of QCD, we work out a new color decomposition for n-point tree amplitudes in a ...

Investigation of 3D Wave Propagation in Foam‐Core Functionally Graded Material Magneto‐Piezoelectric Smart Nanoplates

Advanced Engineering Materials, EarlyView.
This study reveals how wave propagation in FG‐MEE nanoplates can be tuned via material gradients, porosity, and external fields. Using NSGT and Hamilton's principle, analytical solutions capture key dispersion behaviors. Findings highlight the potential of smart nanoplates for adaptive control in high‐performance applications like sonar and aerospace ...

Kinematics of the outer pseudorings and the spiral structure of the Galaxy [PDF]

, 2008
The kinematics of the outer rings and pseudorings is determined by two processes: the resonance tuning and the gas outflow. The resonance kinematics is clearly observed in the pure rings, while the kinematics of the gas outflow is manifested itself in ...

Adaptive Control of Robot Manipulators With Uncertain Kinematics and Dynamics [PDF]

IEEE Transactions on Automatic Control, 2014
In this note, we investigate the adaptive control problem for robot manipulators with both the uncertain kinematics and dynamics. We propose two adaptive control schemes to realize the objective of task-space trajectory tracking irrespective of the ...

Self‐Powered Real‐Time Temperature Sensing Based on Flexible Ionic Elastomer on Triboelectric Nanogenerators

Advanced Functional Materials, EarlyView.
This study introduces a self‐powered real‐time ionic TENG temperature sensing system for flexible thermal management with high and real‐time temperature monitoring. Ionic liquids and elastomer chains are investigated under temperature via electrochemical and physical analysis, resulting in enhancing thermal sensitivity and output performance on TENG ...

Iterated amplitudes in the high-energy limit [PDF]

, 2008
We consider the high-energy limits of the colour ordered four-, five- and six-gluon MHV amplitudes of the maximally supersymmetric QCD in the multi-Regge kinematics where all the gluons are strongly ordered in rapidity.
