For an arbitrary tree T, a T-matching in G is a set of vertex-disjoint subgraphs of G which are isomorphic to T. A T-matching which is a spanning subgraph of G is called a perfect T-matching. For any t-vertex tree T we find a threshold probability function jj = jj( n) for the existence of r edge-disjoint perfect T-matchings in a random graph G(n,p).

We begin by recalling some well-known facts. The natural action of the symmetric group Sn on jRn can be viewed as a group generated by reflections. The reflections in Sn are the orthogonal reflections across the hyperplanes H jj = {x E jRnlxj = x j }, 1 '.5, i < j '.5, n. The Sn-action extends to Cn (= jRn ®C) and the set of points with nontrivial isotropy group is U H jj ® C. Let M denote the ...

This paper deals with semi-online scheduling on two parallel batch processing machines with jobs’ nondecreasing processing times. Our objective is to minimize the makespan. A batch processing machine can handle up to B jobs simultaneously. We study unbounded model which means that B is sufficiently large. The jobs that are processed together construct a batch, and all jobs in a batch start and ...

We assessed the effects of in vivo phototherapy of Gunn rats on the activity of hepatic microsomal mixed-function monoxygenases and on the in vivo pharmacokinetics of [14C]HB. In experiment 1 no serial changes were seen in activities of hexobarbital hydroxylase or benzo(a)pyrene hydroxylase in hepatic microsomes isolated after 2, 4 or 7 days from homozygous jaundiced female Gunn rats exposed to...

Branch testing, for example, seeks to cover all branches in a piece of code, but when it is performed, as well as branches, other program elements, such as statements or puses, will necessarily be covered. The contemporaneous coverage of these other elements is referred to as “collateral coverage”. An understanding of the extent of the collateral coverage of the various program elements that is...

Grafting has been found to effectively reduce the prickly nature of Zanthoxylum armatum seedlings, but molecular mechanisms are unclear. A comparative transcriptome analysis was performed on stems (JJ) and leaves (JY) grafted (SJ) (SY) non-grafted seedlings. The authors obtained 3097, 2124, 5995, 5043 differentially expressed genes from JJ vs. SJ, JY SY, JJ, SY SJ with 17 co-expressed genes. RN...
