The Stein-Lovász Theorem can be used to get existence results for some combinatorial problems using constructive methods rather than probabilistic methods. In this paper, we discuss applications of the Stein-Lovász Theorem to some combinatorial set systems and arrays, including perfect hash families, separating hash families, splitting systems, covering designs, lotto designs and ∆-free systems...

increasing of wood demand is currently one of the most important problems in our society. different clones of populus nigra from salicacea as a native fast-growing species have a good potential for planting in wide scale. but because of the ecological differences in the field, especially. temperature alterations, segregation of the cold resistant clones in relation to in seedling stage establis...

Pistachio is one of the most important horticultural products of Iran with special economic importance. In average 70% of Iran pistachio are exported. Aflatoxin is secondary metabolites of fungus such as Aspergillus flavus and A. parasiticus. If favorite condition is prepared for stabilization of fungi spores producing Aflatoxin, the first pistachio contamination to Aflatoxin occurs in orchard....

This paper briefly reviews the applicability of casebased reasoning (CBR) to code understanding and generation. The paper suggests that case-based techniques are already common in code understanding and generation but are seldom labelled as CBR. Some examples of ‘explicit’ and ‘covert’ CBR are briefly examined. It is suggested that extending the existing code understanding and generation method...

We consider the simultaneous wireless information and power transfer in two-phase decode-and-forward two-way relaying networks, where a relay harvests the energy from the signal to be relayed through either power splitting or time splitting. Here, we formulate the resource allocation problems optimizing the time-phase and signal splitting ratios to maximize the sum rate of the two communicating...

This talk reviews some recent results on the NLL resummed smallx gluon splitting function, as determined including renormalisation-group improvements. It also discusses the observation that the LO, NLO, NNLO, etc. hierarchy for the gluon splitting function breaks down not when αs ln 1/x ∼ 1 but rather for αs ln 2 1/x ∼ 1. It is well-known that the resummation of leading-logarithms of x (LLx) [1...

although cardiovascular disease (cvd) is typically associated with middle- or old-age, the atherosclerotic process often initiates early in childhood and is occurring at an increasing rate. there is a consensus that changes in life-style have driven the current epidemic. adverse changes in physical activity, nutrition, and sleep behavior have been strongly linked to the development of a host of...
