On BC-trees and BC-subtrees
A BC-tree (block-cutpoint-tree) is a tree (with at least two vertices) where the distance between any two leaves is even. Motivated from the study of the “core” of a graph, BC-trees provide an interesting class of trees. We consider questions related to BC-trees as an effort to make modest progress towards the understanding of this concept. Constructive algorithms are provided for BC-trees with...
متن کاملAction Language BC+
Action languages are formal models of parts of natural language that are designed to describe effects of actions. Many of these languages can be viewed as high level notations of answer set programs structured to represent transition systems. However, the form of answer set programs considered in the earlier work is quite limited in comparison with the modern Answer Set Programming (ASP) langua...

Gershtein S. In the framework of potential models for heavy quarkonium the mass spectrum for the system (¯ bc) is considered. Spin-dependent splittings, taking into account a change of a constant for effective coulomb interaction between the quarks, and widths of radiative transitions between the (¯ bc) levels are calculated. In the framework of QCD sum rules, masses of the lightest vector B * ...

hydrotactic. Alternatively, cells may rely on sensing parameters that vary with desiccation, such as salinity, temperature or the presence of other chemical species. We have also seen this behaviour in other desert-soil cyanobacteria — for example, the common Microcoleus vaginatus . If it is widespread among prokaryotes, this response may be crucial for survival and dispersal in terrestrial env...

principle that most of us are linked by short chains of acquaintances — was first investigated as a question in sociology and is a feature of a range of networks arising in nature and technology. Experimental study of the phenomenon revealed that it has two fundamental components: first, such short chains are ubiquitous, and second, individuals operating with purely local information are very a...
