Examining the evolution of maximum valence quark distribution, qV, weighted by Bjorken x, h(x,t)?xqV(x,t), it is observed that h(x,t) at peak becomes a one-parameter function; h(xp,t)=?(xp(t)), where xp position peak, t=logQ2, and Q2 resolution scale. This observation used to derive new model-independent relation which connects partial derivative parton distribution functions (PDFs) in quantum ...

The Extreme Programming (XP) software development methodology seems appropriate for some teams or projects. Anecdotal stories from developers who have adopted XP are often favorable. However, there is little empirical evidence to support or refute claims regarding XP. The Extreme Programming Evaluation Framework (XP-EF) provides a benchmark measurement framework for researchers and practitioner...

In the previous lecture we saw that there always exists a Nash equilibrium in two-player zero-sum games. Moreover, the equilibrium enjoys several attractive properties such as polynomial-time tractability, convexity of the equilibrium set, and uniqueness of players’ payoffs in all equilibria. In this lecture we explore whether we can generalize this theorem to multi-player zero-sum games. Befor...

In a placebo-controlled clinical trial, the dietary supplement XP-828L (commercialized as Dermylex) demonstrated potential to reduce symptoms associated with mild-to-moderate psoriasis at a dose regimen of 5 g daily for 56 days. However, recent in vivo data in humans and animals suggest a daily dose of 800 mg could be more efficient than a 5-g dose. However, no well-structured clinical study ha...

XP is a light-weight methodology suited particularly for small-sized teams that develop software which has only vague or rapidly changing requirements. The discipline of systems engineering knows it as approach of incremental system change or also of “muddling through”. In this paper, we introduce three well known methods of reorganizing companies, namely, the holistic approach, the incremental...

A random variableX is geometrically infinitely divisible iff for every p ∈ (0, 1) there exists random variable Xp such that X d = ∑T (p) k=1 Xp,k, where Xp,k’s are i.i.d. copies of Xp, and random variable T (p) independent of {Xp,1, Xp,2, . . .} has geometric distribution with the parameter p. In the paper we give some new characterization of geometrically infinitely divisible distribution. The...

For isolation of the gene responsible for xeroderma pigmentosum (XP) complementation group A, plasmid pSV2gpt and genomic DNA from a mouse embryo were cotransfected into XP2OSSV cells, a group-A XP cell line. Two primary UV-resistant XP transfectants were isolated from about 1.6 X 10(5) pSV2gpt-transformed XP colonies. pSV2gpt and genomic DNA from the primary transfectants were again cotransfec...

BACKGROUND The Xpert™ MTB/RIF (XP) has a higher sensitivity than sputum smear microscopy (70% versus 35%) for TB diagnosis and has been endorsed by the WHO for TB high burden countries to increase case finding among HIV co-infected presumptive TB patients. Its impact on the diagnosis of smear-negative TB in a routine care setting is unclear. We determined the change in diagnosis, treatment and ...

Patients with Xeroderma pigmentosum and defective DNA excision repair can be distinguished as a rapid (r-XP) and slow (s-XP) complementing variety. When fused with normal cells, fibroblasts from the r-XP are complemented rapidly and in the absence of protein synthesis while those from the s-XP are complemented slowly by a process partly, but not entirely, dependent on protein synthesis. Heterok...
