Assessment and Measurement of the Side-Effects of an Evidence-Based Intervention with an Advanced Smart Cricket Ball Exemplified by a Case Report on Correcting Illegal Bowling Action [PDF]
Correcting an illegal bowling action in cricket through technical intervention involves modifying a movement pattern. This study evaluated the success of an intervention aimed at correcting the suspect actions of two off-spin bowlers and assessed whether

Quasiperiodic spin-orbit motion and spin tunes in storage rings [PDF]
We present an in-depth analysis of the concept of spin precession frequency for integrable orbital motion in storage rings. Spin motion on the periodic closed orbit of a storage ring can be analyzed in terms of the Floquet theorem for equations of motion

Experimental model for the description of the behaviour of a 9-mm projectile at a target
Analysis of crime scenes involving single-fire-gun projectiles requires the determination of the direction of arrival of a projectile at the target and other factors to reconstruct events.

Griffin and Hero-Deer in cosmological composition, as practical model of social development of ancient societies, on example of Pazyryk carpet (V century BC) [PDF]
The Eurasian tradition in general and, in particular, in the Scythian outlook, reveal two astral tradition of constructing social relations, by analogy with the observed picture of the sky, which is reflected in the monuments of visual culture.

Analyzing the Motion of Symmetric Tops Without Recurring to Analytical Mechanics
Characterizing the dynamics of heavy symmetric tops is essential in several fields of theoretical and applied physics. Accordingly, a series of approaches have been developed to describe their motion.

Is OJ 287 a Single Supermassive Black Hole?
Light curves for more than century optical photometric observations of the blazar OJ 287 reveals strong flares with a quasi-period of about 12 years. For a long time, this period has been interpreted by processes in a binary black hole system. We propose
