PURPOSE To examine the effect of recall timing on training-session rating of perceived exertion (sRPE) in a population of athletes well familiarized with the method and procedures during a 5-d training microcycle. METHODS Fifty-one top-class field referees (FRs) (age 38.4 ± 3.3 y, height 181 ± 5.6 cm, body mass 76.8 ± 6.8 kg, body-mass index 23.4 ± 1.7 kg/m2, body fat 20.4% ± 3.6%, internatio...

Motivated by applications in online dating and kidney exchange, we study a stochastic matching problem in which we have a random graph G given by a node set V and probabilities p(i, j) on all pairs i, j ∈ V representing the probability that edge (i, j) exists. Additionally, each node has an integer weight t(i) called its patience parameter. Nodes represent agents in a matching market with dicho...
