The Hong Kong Jubilee Sports Centre was established in 1981 as the National Training Centre for elite sportsmen and sportswomen in Hong Kong. There were 11 residential sports: soccer, badminton, table tennis, tennis, fencing, gymnastics, squash, rowing, windsurfing, track and field, and swimming, each with a system of professional coaches and supporting technical staff. A number of non-resident...

THIS STUDY AIMED TO EXAMINE EFFECT OF PHYSICAL EXERCISE ON MOTOR TIMING: personal, maximum and "once per second" tapping. The acute effect was examined by comparing the baseline tapping with that after acute exercise in 9 amateur athletes, 8 elite synchronous swimmers and 9 elite biathletes. Then the baseline tapping was compared among athletes of different sports and professional levels (15 el...

In order to improve the problem of premature convergence and computational efficiency of traditional differential evolution algorithm in solving high-dimensional problems, an improved differential evolution (HMSDE) algorithm based on combing elite synergy strategy, multi-population strategy and dynamic adaptive strategy is proposed in this paper. In the proposed HMSDE algorithm, the population ...

When Walter Benjamin wrote his famous essay The Work of Art in the Age of Mechanical Reproduction, he shone a light on the cultural changes inherent in technology’s ability to infinitely reproduce and distribute art. One of the important consequences of this development was the democratization of art’s availability, allowing the general population to experience artwork that they would otherwise...

To solve the slow convergence speed, low precision in later period and tedious parameter setting of differential evolution when applied to complex optimization functions, an improved differential evolution algorithm (dn-DADE) based on dynamic adaptive strategy is proposed. Firstly, the elite solutions of current population are utilized in the new mutation strategy (DE/current-to-dnbest/1) to gu...

The popularity and influence of reviews, make sites like Yelp ideal targets for malicious behaviors. We present Marco, a novel system that exploits the unique combination of social, spatial and temporal signals gleaned from Yelp, to detect venues whose ratings are impacted by fraudulent reviews. Marco increases the cost and complexity of attacks, by imposing a tradeoff on fraudsters, between th...

Phytophthora cinnamomi causes a severe root rot in avocado, Persea americana. Breeding tolerant rootstocks is thought to be the most promising method for phytophthora root rot disease control but breeding avocado is challenging. The avocado flowering syndrome (synchronous protogynous dichogamy), combined with high flowering and low fruit set, render controlled pollination exceedingly difficult....

During the early Turkish republic karagöz shadow theatre’s Ottoman patterns were transformed. Reformers attempted to restrict coffeehouses where the art had flourished and developed written texts to replace the improvised practice of the past. They sponsored performances in government-supported community centers and created shows to promote government policies. The efforts meant that an art, wh...
