Solving Two Puzzles in One Go: Quintessence from a Decaying Dark Matter
Houri Ziaeepour
The mystery of the Dark energy is not just its smallness. The extreme fine tuning of its density in the Early Universe such that it permits galaxy formation before creating a new i…
An exact effective two-qubit gate in a chain of three spins
Man-Hong Yung, Debbie W. Leung, Sougato Bose
We show that an effective two-qubit gate can be obtained from the free evolution of three spins in a chain with nearest neighbor XY coupling, without local manipulations. This gate…
Electronic structures of UTSn (T=Ni, Pd) using photoemission spectroscopy
J. -S. Kang, S. C. Wi, J. H. Kim +4
The electronic structures of the localized systems UTSn (T=Ni, Pd) have been investigated using photoemission spectroscopy (PES). The extracted U PES spectra of UTSn (T=N…
The Best Trail Algorithm for Assisted Navigation of Web Sites
Richard Wheeldon, Mark Levene
We present an algorithm called the Best Trail Algorithm, which helps solve the hypertext navigation problem by automating the construction of memex-like trails through the corpus.…
The number of k-intersections of an intersecting family of r-sets
John Talbot
The Erdos-Ko-Rado theorem tells us how large an intersecting family of r-sets from an n-set can be, while results due to Lovasz and Tuza give bounds on the number of singletons tha…
Power Law Distributions in Class Relationships
Richard Wheeldon, Steve Counsell
Power law distributions have been found in many natural and social phenomena, and more recently in the source code and run-time characteristics of Object-Oriented (OO) systems. A p…
