State feedback controllers can be used to restore predictable behavior of asynchronous sequential machines that are afflicted by a critical race. The present note presents necessary and sufficient conditions for the existence of such controllers. The controllers also assign a specified behavior to the controlled machine. Copyright ©IFAC 2002

purpose the aims of the present study were to investigate (i) the changes in participation and performance and (ii) the gender difference in triple iron ultra-triathlon (11.4 km swimming, 540 km cycling and 126.6 km running) across years from 1988 to 2011. methods for the cross-sectional data analysis, the association between with overall race times and split times was investigated using simple...

purpose the aim of this study was to evaluate predictor variables of race time in female ultra-endurance inliners in the longest inline race in europe. methods we investigated the association between anthropometric and training characteristics and race time for 16 female ultra-endurance inline skaters, at the longest inline marathon in europe, the ‘inline one-eleven’ over 111 km in switzerland,...

Abstract We use stock exchange message data to quantify the negative aspect of high-frequency trading, known as “latency arbitrage.” The key difference between and widely familiar limit order book is that contain attempts trade or cancel fail. This allows researcher observe both winners losers in a race, whereas you cannot see losers, so directly races. find latency arbitrage races are very fre...

Why do race stereotypes take the forms they do? Life history theory posits that features of the ecology shape individuals' behavior. Harsh and unpredictable ("desperate") ecologies induce fast strategy behaviors such as impulsivity, whereas resource-sufficient and predictable ("hopeful") ecologies induce slow strategy behaviors such as future focus. We suggest that individuals possess a lay und...
