This paper provides an axiomatic characterization of two rules for comparing alternative sets of objects on the basis of the diversity that they offer. The framework considered assumes a Þnite universe of objects and an a priori given ordinal quadernary relation that compares alternative pairs of objects on the basis of their ordinal dissimilarity. Very few properties of this quadernary relatio...

Given a family of subsets S = {S1, . . . , Sm} over a set of elements X = {x1, . . . , xn} and an integer p, max k-set cover consists of finding a set T of at most k subsets covering at least p elements. This problem, when parameterized by k, can be easily shown to be W[2]-hard. Here, we settle the parameterized complexity of max k-set cover under several parameters as max{k,∆}, where ∆ = maxi{...

A Pall Maxi-Gaskleen purifier of the Pall AresKleen family of gas purification products was evaluated for its efficacy in reducing oxygen impurities in a silicon germanium (SiGe) deposition process for a strained silicon application at a major IDM in the US. Impact on process parameters such as hydrogen pre-bake temperature and interfacial/within-film oxygen concentration were studied as a func...

We study the complexity of several parameterizations for max k-set cover. Given a family of subsets S = {S1, . . . , Sm} over a set of elements X = {x1, . . . , xn} and an integer p, max k-set cover consists of finding a set T of at most k subsets covering at least p elements. This problem, when parameterized by k, is W[2]-hard. Here, we settle the multiparameterized complexity of max k-set cov...

The Maxi-chloride channel was the first ion channel described by electrophysiological methods in placenta. Because it is difficult to access a complex epithelium such as the placenta for electrophysiological procedures, the studies of ion channels from placental membranes have been performed only very recently. It was only in 1993 that a direct demonstration of a high-conductance chloride chann...

The existence of a large conductance voltage sensitive chloride channel is documented in undifferentiated cells (myoblasts) of the L6 rat muscle cell line. At this stage of development the resting membrane conductance is dominated by potassium ions only (Kidokoro 1975). The conductance of the channel in symmetrical 120 mmol/l choline chloride is 331 +/- 4 pS. The probability of the channel bein...
