Let G(V,E1) and G (V,E2) be two networks on the same vertex set V and consider the union of edges G(V,E1 ∪ E2). This paper studies the stability of the Degree, Betweenness and Eigenvector Centrality of the resultant network, G(V,E1 ∪ E2). Specifically assume v max and v max are the highest centrality vertices of G(V,E1) and G(V,E1 ∪ E2) respectively, we want to find Pr(v max = v max). ar X iv :...

Two possible isomers of some 1,3-diaryl-H-benzo[f]chromene have been studied using density functional theory. Structures of E1 and E2 isomers were optimized at the B3LYP and MP2 levels with different basis sets. The total electronic energies show that E2 isomer is about 3-5 kcal/mol more stable than E1 isomer and this energy difference is attributed to the planarity of heterocyclic ring and mor...

For the RuIII/II couple in [(bpy)2ClOs(4,4′-bpy)Ru(NH3)5] (bpy ) 2,2′-bipyridine; 4,4′-bpy ) 4,4′bipyridine), E1/2 varies linearly with the donor number (DN) of the solvent with a slope of -26 ( 3 mV/DN unit ranging from nitromethane to dimethyl sulfoxide. For the OsIII/II couple, the variation is -3 ( 1 mV/DN unit. Plots of ∆E1/2 ) E1/2(2) E1/2(1) vs DN (E1/2 is the half wave potential for the...

Example 1 Lets consider the integers from 1 to 10,000. The properties are defined as follows: E1 = property that an integer is divisible by 4 E2 = property that an integer is divisible by 5 E3 = property that an integer is divisible by 6 The probabilities of individual divisability are easily computed: Pr [E1] = probability the number is divisible by 4 = 1=4 Pr [E2] = probability the number is ...

Exercise 1 Consider the rolling of two six-sided dice. Let E1 be the event that the dice land on the same number, and E2 the event that their sum is greater than six. 1. What is the size of E2 (i.e how many outcomes does it contain)? 2. What is E1 X E2? 3. What is the size of E1 Y E2? Solution: 1. Let (x, y) denote both the outcome x of the first die and the outcome y of the second. Then E2 = t...

UNLABELLED The measure of changes in synaptic dopamine (DA) concentration in response to the psychostimulant drug methylphenidate (MP) has been used as an indicator of responsiveness of the DA system. The purpose of this study was to assess the reproducibility of these measures. METHODS Seven healthy subjects were scanned with PET and [11C]raclopride twice in the same day: 7 min after placebo...

Natural steroidal hormone estrone (E1) was treated with the white rot fungus Phanerochaete sordida YK-624 under ligninolytic condition with low-nitrogen and high-carbon culture medium. E1 decreased by 98% after 5 d of treatment and the activities of ligninolytic enzymes, manganese peroxidase (MnP) and laccase, were detected during treatment, which suggested that the disappearance of E1 is relat...

adenoviruses are used extensively to deliver genes into mammalian cells, particularly where there is a requirement for high-level expression of transgene products in cultured cells, or for use as recombinant viral vaccines or in gene therapy. in spite of their usefulness, the construction of adenoviral vectors (adv) is a cumbersome and lengthy process that is not readily amenable to the generat...

A subline of 293 cells able to grow in suspension culture has been developed by passage of 293 cells through nude mice. This new line, designated 293N3S, grows with a doubling time of approximately 30 h, continues to express adenovirus 5 early region 1 (E1) antigens, and remains permissive for adenovirus 5 host range mutants defective in E1 functions.

A precise balance between quiescence and proliferation is crucial for the lifelong function of hematopoietic stem cells (HSCs). Cyclins E1 and E2 regulate exit from quiescence in fibroblasts, but their role in HSCs remains unknown. Here, we report a non-redundant role for cyclin E1 in mouse HSCs. A long-term culture-initiating cell (LTC-IC) assay indicated that the loss of cyclin E1, but not E2...
