Asymmetric ion acceleration in laser-produced magnetized collisionless shocks [PDF]

Matter and Radiation at Extremes
Quasi-hemispherical magnetized collisionless shocks have been generated at the SG-II laser facility through the interaction between a laser-produced supersonic plasma flow and a magnetized ambient plasma, exhibiting an angular asymmetric shock profile ...

Angular-Momentum Evolution in Laser-Plasma Accelerators [PDF]

Physical Review Letters, 2013
The transverse properties of an electron beam are characterized by two quantities, the emittance which indicates the electron beam extend in the phase space and the angular momentum which allows for non-planar electron trajectories. Whereas the emittance of electron beams produced in laser- plasma accelerator has been measured in several experiments ...

An automated methodology for performing time synchronous averaging of a gearbox signal without speed sensor [PDF]

, 2007
In this paper we extend a sensorless algorithm proposed by Bonnardot et al. for angular resampling of the acceleration signal of a gearbox submitted to limited speed fluctuation.

State Derivation of a 12-Axis Gyroscope-Free Inertial Measurement Unit

Sensors, 2011
The derivation of linear acceleration, angular acceleration, and angular velocity states from a 12-axis gyroscope-free inertial measurement unit that utilizes four 3-axis accelerometer measurements at four distinct locations is reported.

Large-uncertainty intelligent states for angular momentum and angle [PDF]

, 2005
The equality in the uncertainty principle for linear momentum and position is obtained for states which also minimize the uncertainty product. However, in the uncertainty relation for angular momentum and angular position both sides of the inequality are

GNSS gyroscopes: determination of angular velocity and acceleration with very high-rate GNSS

Satellite Navigation
Although global navigation satellite systems (GNSS) have been routinely applied to determine attitudes, there exists no literature on determining angular velocity and/or angular acceleration from GNSS.

Orbital angular momentum: origins, behavior and applications [PDF]

, 2011
As they travel through space, some light beams rotate. Such light beams have angular momentum. There are two particularly important ways in which a light beam can rotate: if every polarization vector rotates, the light has spin; if the phase structure ...

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.
