INTRODUCTION: A number of surveys have shown that the golf swing is increasingly being recognized as a potential cause of lower back injuries. Although many researchers have been interested in seeking a “perfect” golf swing to improve performance, surprisingly, few studies have investigated the potential causes of injury such as back pain. The forces generated by the musculature surrounding the...

BACKGROUND To introduce the Chung's swing technique for small-incision lenticule extraction (SMILE). METHODS A total of 112 eyes of 56 patients were included in this study. Patients were divided into two groups: 52 eyes of 26 patients were treated with SMILE using a traditional method (traditional group) and 60 eyes of 30 patients were treated with SMILE using the Chung's swing technique (swi...

In this investigation, we obtained data that support the hypothesis that afferent signals associated with hip flexion play a role in initiating the swing-to-stance transition of the hind legs in walking cats. Direct evidence came from observations in walking decerebrate cats. Assisting the flexion of the hip joint during swing advanced the onset of activity in ankle extensor muscles, and this a...

Capturability of a robot determines whether it is able to capture a robot within a number of steps. Current capturability analysis is based on stance leg dynamics, without taking adequate consideration on swing leg. In this paper, we combine capturability-based analysis with swing leg dynamics. We first associate original definition of capturability with a timemargin, which encodes a time seque...

Social unrest often erupts suddenly and diffuses quickly. What drives people to overcome their collective action problem and join a riot or protest, turning what is initially a small event into a widespread movement? We address this question by examining the Swing riots of 1830-31. The communication constraints of the time induced spatio-temporal variation in exposure to news about the uprising...

This study considers a practical overhead crane control problem of designing a fuzzy control to ensure that the trolley arrives precisely at its destination; the load swing angle approaches to zero, and the energy of input and states is minimized. Furthermore, the constraints for the overhead crane operation are also considered and satisfied. Those constraints are that when the crane is moving,...

Our recent work within the research project SIMULEKT (Simulating Intonational Varieties of Swedish) includes two approaches. The first involves a pilot perception test, used for detecting tendencies in human clustering of Swedish dialects. 30 Swedish listeners were asked to identify the geographical origin of Swedish native speakers by clicking on a map of Sweden. Results indicate for example t...

The main approaches to dual representations of multiple optimal stopping problems are the marginal and pure martingale approaches of Meinshausen and Hambly [17] and Schoenmakers [20], respectively. In this paper we show that these dual representations can be derived in a simple unified manner using the general duality theory based on information relaxations that was developed independently by B...
