background: running standard journal clubs is one of the important goals of postgraduate education. students should update their knowledge and learn critical appraisal skill. this study aimed to compare quality of journal clubs in mashhad dental school in order to improve educational and appraisal structure of journal clubs. methods: this quasi-experimental study was conducted on journal clubs ...

This paper presents a new visual tracking technology that relies on the use of a global motion model to achieve robustness. We demonstrate its effectiveness for the purpose of retrieving the 2D spatio-temporal trajectory of a golf club head from ordinary video sequences of golf swings, so that information about club orientation, local speed and acceleration can also be obtained. We have integra...

Drug abuse is often seen as a unitary phenomenon, partly as a result of the discovery over the past three decades of shared mechanisms of action for addictive substances. Yet the pattern of drug taking is often very different from drug to drug. This is particularly evident in the case of 'club drugs', such as ketamine. Although the number of ketamine abusers is relatively small in the general p...

This paper describes the application of the first fully wireless network of inertial sensors for full-body 3-D motion capture – the Orient-2 system, to real-time on-body analysis of the golf swing. The golfer-club system is modelled as a double pendulum. The factors which affect the efficiency of the golf swing are outlined, such as the length of the back swing, the wrist-cock angle, swing plan...

This paper discusses the three-dimensional kinematics and kinetics of a golf swing as performed by 84 male and one female amateur subjects of various skill levels. The analysis was performed using a variable full-body computer model of a human coupled with a flexible model of a golf club. Data to drive the model was obtained from subject swings recorded using a multi-camera motion analysis syst...

Radial club hand refers to deficiency along the preaxial side of the extremity. Complete absence is the most common longitudinal deficiency. It is diagnosed after inspection of the forearm and an X-ray. It is however imperative to look for associated congenital abnormalities or syndromes regarding the cardiovascular system, renal system, vertebral column, blood cells and digestive system of the...

The Cajal Club is a small organization of neuroscientists that has met annually since it was founded in 1947. The fourteen founding members voted at its organizational meeting that the Club be named to honor the great Spanish Neuroscientist, Santiago Ramon y Cajal. The beginnings and the early development of the Cajal Club that was led by Professor Wendell J. S. Krieg, a distinguished neuroanat...

This study investigated the relationships between golfer hub path trajectories and interaction kinetics, and club behavior. An equation of motion describing a flexible golf club system was derived and solved to yield time and club position deflection behavior during the downswing. This equation was applied to three diverse subjects whose kinematic and kinetic information was used to drive the s...

This experiment assessed whether or not a golf club impact acoustic testing methodology using a fixed golf club/launched golf ball setup would record less error in the captured acoustic signatures than industry standard methodologies (a stationary ball/swinging club setup). Two steel-shafted golf drivers were tested using this new system that launched golf balls using a pressurized air cannon i...

We propose a novel method of community detection that is computationally inexpensive and possesses physical significance to a member of a social network. This method is unlike many divisive and agglomerative techniques and is local in the sense that a community can be detected within a network without requiring knowledge of the entire network. A global application of this method is also introdu...
