Kinematical superspaces [PDF]

open access: yesJournal of High Energy Physics, 2019
Abstract We classify N =1 d = 4 kinematical and aristotelian Lie superalgebras with spa- tial isotropy, but not necessarily parity nor time-reversal invariance. Employing a quater- nionic formalism which makes rotational covariance manifest and simplifies many of the calculations, we find a list of 43 isomorphism classes of Lie ...

Local kinematics and the local standard of rest [PDF]

open access: yes, 2009
We re-examine the stellar kinematics of the solar neighbourhood in terms of the velocity υ of the Sun with respect to the local standard of rest. We show that the classical determination of its component Vin the direction of Galactic rotation via Str ...

Internal kinematics of spiral galaxies in distant clusters IV. Gas kinematics of spiral galaxies in intermediate redshift clusters and in the field [PDF]

open access: yes, 2010
(Abridged) We trace the interaction processes of galaxies at intermediate redshift by measuring the irregularity of their ionized gas kinematics, and investigate these irregularities as a function of the environment (cluster versus field) and of ...

Comparison between Accelerometer and Gyroscope in Predicting Level-Ground Running Kinematics by Treadmill Running Kinematics Using a Single Wearable Sensor

open access: yesSensors, 2021
Wearable sensors facilitate running kinematics analysis of joint kinematics in real running environments. The use of a few sensors or, ideally, a single inertial measurement unit (IMU) is preferable for accurate gait analysis.

Gravitational radiation from color-kinematics duality [PDF]

open access: yesJournal of High Energy Physics, 2018
A bstractWe perturbatively calculate classical radiation in Yang-Mills theory and dilaton gravity, to next-to-leading order in couplings. The radiation is sourced by the scattering of two relativistic massive scalar sources with the dynamical effect ...

Age-Related Changes in Inter-Joint Interactions for Global and Local Kinematics While Standing

open access: yesIEEE Transactions on Neural Systems and Rehabilitation Engineering, 2023
Inter-joint interactions are involved in human standing. These interactions work not only for global kinematics that control the center of mass (COM) of the entire body, but also for local kinematics that control joint angular movements.

Inertial Sensor-Based Lower Limb Joint Kinematics: A Methodological Systematic Review

open access: yesItalian National Conference on Sensors, 2020
The use of inertial measurement units (IMUs) has gained popularity for the estimation of lower limb kinematics. However, implementations in clinical practice are still lacking. The aim of this review is twofold—to evaluate the methodological requirements

Structure and Kinematics of Early-Type Galaxies from Integral Field Spectroscopy [PDF]

open access: yes, 2016
Observations of galaxy isophotes, long-slit kinematics, and high-resolution photometry suggested a possible dichotomy between two distinct classes of elliptical galaxies. But these methods are expensive for large galaxy samples.

“Kinematics and Dynamics” [PDF]

open access: yesNature, 1888
MAY I ask a short space in your columns to refer to a few points in Prof. Greenhill's review of my book on “Kinematics and Dynamics,” published in your issue of February 16 (p. 361). I shall be as brief as possible.
