We study composition-valued continuous-time Markov chains that appear naturally in the framework of Chinese Restaurant Processes (CRPs). As time evolves, new customers arrive (up-step) and existing leave (down-step) at suitable rates derived from ordered CRP Pitman Winkel (Ann. Probab. 37 (2009) 1999–2041). relate such up-down CRPs to splitting trees Lambert 38 (2010) 348–395) inducing spectral...

There is growing evidence that oscillatory brain activity is involved in Gestalt recognition processes. However, it is still a question at issue whether this activity is correlated to high-level cognitive top-down processes or to perceptual bottom-up processes [1]. In contrast imaginary events are supposed to be pure top-down processes, which makes them a possibility to differenciate between bo...
