We study the effect of the neutron star spin – kick velocity alignment observed in young radio pulsars on the coalescence rate of binary neutron stars. Two scenarios of the neutron star formation are considered: when the kick is always present and when it is small or absent if a neutron star is formed in a binary system due to electroncapture degenerate core collapse. The effect is shown to be ...

Accurate determination of retinal vessel width measurement is important in the study of the haemodynamic changes that accompany various physiological and pathological states. Currently the width at the half height of the transmittance and densitometry profiles are used as a measure of retinal vessel width. A consistent phenomenon of two 'kick points' on the slopes of the transmittance and densi...

Little attention has been given to the rotational kinematics of the rugby union place kicking performance, especially in a field setting. The place kick is a means to score points. By maximizing the distance and accuracy a kicker is able to achieve increases in the number of point scoring opportunities available to a team. The hypothesis of this study was that there was a relationship between d...

Generic black hole binaries radiate gravitational waves anisotropically, imparting a recoil, or kick, velocity to the merger remnant. If a component of the kick along the line of sight is present, gravitational waves emitted during the final orbits and merger will be gradually Doppler shifted as the kick builds up. We develop a simple prescription to capture this effect in existing waveform mod...

This paper reviews research on decision-making behavior of both goalkeeper and penalty taker during penalty kick situations in association football. Specifically, it adopts an ecological dynamics perspective on the behavior of both penalty taker and goalkeeper exemplifying how each might constrain the other’s decisions. This conceptual framework is elucidated to suggest key ideas for designing ...

We study the effect of the kick velocity – neutron star spin alignment observed in young radio pulsars on the coalescence rate of binary neutron stars. The effect is shown to be especially strong for large kick amplitudes and tight alignments, reducing the galactic rate of binary neutron star coalescences up to an order of magnitude with respect to the rates calculated for random kicks. The spi...

Problem statement: Kicking is one of the most important skills in indoor soccer. Kicking accuracy is an important component of this skill. The instep kick is often used when tacking a penalty kicks, as a combination of increased ball speed and kick accuracy can be maintained. The purpose of this research was to compare selected kinematic parameters of the kicking foot during the performance of ...

Prerecorded video footage of 9 female and 13 male Olympic level athletes swimming underwater by using the dolphin kick was analyzed and comparisons of the stroke kinematics were made with a previous analysis of cetacean swimming conducted by Rohr and Fish (Rohr, J. J., & Fish, F. E. (2004). Strouhal numbers and optimization of swimming by odontocete cetaceans. The Journal of Experimental Biolog...

Two hyperheuristics are proposed as entries for the 2011 Cross-domain Heuristic Search Challenge (CHeSC), namely DynamicILS and BiasILS; both are simple adaptations of Iterated Local Search (ILS). 1 Iterated Local Search Iterated Local Search (ILS) [3] is a metaheuristic search technique which aims to find good solutions to difficult combinatorial optimisation problems in a reasonable amount of...
