This paper shows that linear time μ-calculus with sequential composition defines exactly those properties that are expressible with alternating context-free grammars for ω-words. This helps to understand the expressive power of modal μ-calculus with a chop operator and provides a logical characterisation of the class of alternating context-free languages.

Since neither a single high-precision 3D coordinate laser point cloud nor oblique image of spectral information can make the computer understand data as human, in order to accurately and completely object real world, this paper, fusion is studied for understanding application buildings by establishing BIM model. Firstly, are acquired different acquisition methods. Laser fused installation param...

During DNA replication replicative polymerases move in discrete mechanical steps along the DNA template. To address how the chemical cycle is coupled to mechanical motion of the enzyme, here we use optical tweezers to study the translocation mechanism of individual bacteriophage Phi29 DNA polymerases during processive DNA replication. We determine the main kinetic parameters of the nucleotide i...

A matching in a graph is a set of edges, no two of which share an endpoint. We describe Edmond’s algorithm for finding matchings of maximum cardinality in a graph. For bipartite graphs with edge weights, we also show how to find matchings of maximum weight. It is recommended that the reader draws pictures of the various constructs that we use (such as alternating trees). I was too lazy to incor...

Key points • Expressed by the physiological phasic events of NREM sleep, including arousals, cyclic alternating pattern represents the most complex arrangement of sleep microstructure. • Cyclic alternating pattern is organized in sequences organized in successive cycles. Each cyclic alternating pattern cycle is composed of a phase A (phasic events) and a phase B (background rhythm). • Cyclic al...

Four patients are reported in whom alternation ofRR cycle length before reversion to sinus rhythm occurred during the administration of intravenous verapamil. In 2 of these 4 patients, alternation of cycle lengths was associated with a changing QRS morphology. It is suggested that one patient had a reciprocating tachycardia using dual AV nodal pathways. The alternating cycle lengths in response...
