Non-Markovian stochastic Petri nets have been investigated mainly by means of Markov renewal theory and by the method of supplementary variables. Both approaches provide di erent analytic descriptions of the same system. Numerical algorithms based on these descriptions lead to similar results. Parallel research e ort resulted from the fact that an exact relationship of the two was not known. In...

Require: quartet (a, b, c, d), empirical moments M̂(a,b,c,d), threshold τq Ensure: boolean singly-coupled. 1: M(a,b) = unfold(M̂(a,b,c,d), (a, b), (c, d)) 2: M(a,c) = unfold(M̂(a,b,c,d), (a, c), (b, d)) 3: M(a,d) = unfold(M̂(a,b,c,d), (a, d), (b, c)) 4: for u ∈ {b, c, d} do 5: λ3,(a,u) ← third eigenvalue of M(a,u) 6: end for 7: if maxu(λ3,(a,u)) > τq then 8: return False 9: end if 10: return True A...

Gaussian Directed Acyclic Graphs (DAGs) represent a powerful tool for learning the network of dependencies among variables, task which is primary interest in many fields and specifically biology. Different DAGs may encode equivalent conditional independence structures, implying limited ability, with observational data, to identify causal relations. In contexts however, measurements are collecte...

to investigate the effects of supplementary irrigation and application of different compost levels on morphological traits, yield and yield components of two chickpea cultivars under dry land conditions, a field experiment was conducted at the research field in khoramabad, iran in 2009-2010. the experiment was split split plot based on randomized complete block design with four levels of irriga...

in order to study the effect of spraying of abscisic acid on yield and yield components of chickpea (cicer arietinum l.) under rainfed and supplementary irrigation, a field experiment was conducted in 2010 in agricultural research station of ilam university. a split factorial experiment based on a randomized complete block design was conducted. main plots were composed of two levels of irrigati...

The generalization of simple (two-variable) correspondence analysis to more than two categorical variables, commonly referred to as multiple correspondence analysis, is neither obvious nor well-defined. We present two alternative ways of generalizing correspondence analysis, one based on the quantification of the variables and intercorrelation relationships, and the other based on the geometric...

introduction: performance of painful diagnostic and therapeutic procedures is common in emergency department (ed), and procedural sedation and analgesia (psa) is a fundamental skill for every emergency physician. this studywas aim to compare the efficacy of remifentanil with fentanyl/midazolam in painless reduction of anterior shoulder dislocation. methods: in this randomized, double blind, cli...
