in this study, polystyrene ethylene butylene polystyrene (psebs) was functionalized to prepare mono and bipolar ion exchange membranes. in the case of the bipolar membrane, platinum was used as the intermediate layer. nacl solution of concentration ranging from 5 g/l to 25 g/l was used as the feed solution. a commercially procured ion exchange membrane made of polystyrene divinyl benzene was al...

F 2 -linear pseudorandom number generators are very popular due to their high speed, the ease with which a sizable state space can be created, and provable theoretical properties. However, they suffer from linear artifacts that show as failures in linearity-related statistical tests such binary-rank linear-complexity test. In this article, we give two new contributions. First, introduce transfo...

Wh-questions are answered with a list of pairs when quantified expressions such as "every professor" interact with wh-phrases. The theory of branching quantification is extended to wh-quantifier interactions to account for the question reading associated with list answers. It is also shown that there are several phenomena which would be better explained when functional variables are incorporate...

In German, complex wh-interrogatives can optionally be formed by inserting the 3 person neuter wh-pronoun was in the matrix (Spec,CP) position, instead of long-distance wh-raising. It is generally assumed that 'expletive' was serves as a placeholder for a contentful whexpression lower down in the sentence, which substitutes for it at the level of semantic interpretation. It can be shown, howeve...

The MUS81-EME1 endonuclease maintains metazoan genomic integrity by cleaving branched DNA structures that arise during the resolution of recombination intermediates. In humans, MUS81 also forms a poorly characterized complex with EME2. Here, we identify and determine the structure of a winged helix (WH) domain from human MUS81, which binds DNA. WH domain mutations greatly reduce binding of the ...
