Considerable progress in understanding the dynamics of fish locomotion has been made through studies of live fishes and by analyzing locomotor kinematics, muscle activity, and fluid dynamics. Studies of live fishes are limited, however, in their ability to control for parameters such as length, flexural stiffness, and kinematics. Keeping one of these factors constant while altering others in a ...

Synopsis Considerable progress in understanding the dynamics of fish locomotion has been made through studies of live fishes and by analyzing locomotor kinematics, muscle activity, and fluid dynamics. Studies of live fishes are limited, however, in their ability to control for parameters such as length, flexural stiffness, and kinematics. Keeping one of these factors constant while altering oth...

Tintinnids are a group of ciliated microzooplankton, who spontaneously settle on marine snow and other aggregates. create feeding current that draws particles towards their mouth using crown continuously beating oral cilia. Similarly to not all encountered ingested. However, it is unclear what the mechanistic behavioral basis this selectivity. Here, we used particle tracking velocimetry quantif...

Turbulent-like behaviour is an important and recent ingredient in the investigation of largescale structure formation in the observable universe [1]. Recently, an established statistical method was used to demonstrate the importance of considering chaotic advection (or Lagrange turbulence) in combination with gravitational instabilities in the Λ CDM simulations performed from the Virgo Consorti...

Background. This study aims to analyze the movement of backhand and forehand smash stroke techniques in badminton in three dimensions using a kinematics approach. Objectives. The obtained results were analyzed using a descriptive and quantitative approach. Methods. Furthermore, 24 male badminton players from the university student activity unit with an average age of 19.4 ± 1.6 years, height ...

Objectives: Children aged 10 to 12 years often show dangerous maneuvers during landing, which include increased knee valgus, placing them at higher risk of anterior cruciate ligament (ACL) injuries. The study aimed to investigate the relation of the trunk and hip kinematics with the peak knee abduction angle during single-leg landing among preadolescent female soccer players. Methods: Thirty-s...

A bstract We propose and study a BCJ double-copy of massive particles, showing that it is equivalent to KLT formula with kernel given by the inverse matrix bi-adjoint scalar amplitudes. For models uniform non-zero mass spectrum we demonstrate resulting factors on physical poles up at least 5-particle scattering, color-kinematics duality satisfying numerators always exist. scattering 5 or more p...
