Let v(G) and λ(G) be the number of vertices and the maximum number of disjoint 3-vertex paths in G, respectively. We discuss the following old Problem. Is the following claim true ? (P ) if G is a 3-connected and cubic graph, then λ(G) = bv(G)/3c. We show, in particular, that claim (P ) is equivalent to some seemingly stronger claims (see 3.1). It follows that if claim (P ) is true, then Reed’s...

Psychology journals rarely publish nonsignificant results. At the same time, it is often very unlikely (or “too good to be true”) that a set of studies yields exclusively significant results. Here, we use likelihood ratios to explain when sets of studies that contain a mix of significant and nonsignificant results are likely to be true or “too true to be bad.” As we show, mixed results are not ...

In this paper sets of labelled partial orders are employed as fundamental mathematical entities for modelling nondeterministic and concurrent processes thereby obtaining so-called noninterleaving semantics. Based on closures of sets of labelled partial orders, a simple recursive algebraic language with refinement is given denotational models fully abstract w.r.t. corresponding behaviourally mot...

Introduction The child’s history reveals frequent faringitis accompanied by oral lesions (4-5 episodes/year), billatreal ankle joint swelling and weight loss. Behçet disease (BD) is characterized by a triple-symptom complex of recurrent oral aphthous ulcers, genital ulcers, and uveitis. Hippocrates may have described Behçet disease in the fifth century BC; however, the first description of the ...

There is increasing concern that most current published research findings are false. The probability that a research claim is true may depend on study power and bias, the number of other studies on the same question, and, importantly, the ratio of true to no relationships among the relationships probed in each scientific field. In this framework, a research finding is less likely to be true whe...
