All voting protocols proposed so far, with the exception of a few, have the property that the privacy of the ballot is only computational. In this paper we outline a new and conceptually simple approach allowing us to construct a protocol in which the privacy of the ballot is unconditional. Our basic idea is to modify the protocol of Fujioka, Okamoto and Ohta[10], which uses blind signatures so...

mebudipine is a new dihydropyridine calcium channel blocker, synthesized in our laboratory, for treatment of hypertension. it has shown a better efficacy than other drugs in this group. for assessing the risks of this drug, certain safety tests in the preclinical stage have been performed. in this study mutagenic effect of mebudipine was evaluated using ames assay that could assess the mutageni...

Mass spectrometry combined with liquid chromatography (LC/MS) has become an important analytical methodology in both pharmaceutical and biomolecule analyses. LC/MS, especially with reversed-phase HPLC (RP-LC), is extensively used in the separation and structural identification of pharmaceutical samples. However, many parameters have to be considered when a new LC/MS method is developed for eith...

We present a system for efficient meta-data indexed querying of XML documents. Given the diversity of the information available in XML, it is very useful to annotate XML data with a wide variety of meta-data, such as quality and security assessments. We address the meta-data indexing problem of efficiently identifying the XML elements along a location step in an XPath query, that satisfy meta-d...

Box MIX and MIXAL are available on the UCSD B6700; although, according to Ken Bowles, they are not currently being handled as fully supported products, and there may be some remaining bugs in the systems. However, MIX and MIXAL are available for network users, and Ken says they will be happy to receive notification of any errors found in the MIX and MIXAL and will attempt to get corrections mad...

BACKGROUND Ratings on the quality of healthcare from the consumer's perspective need to be adjusted for consumer characteristics to ensure fair and accurate comparisons between healthcare providers or health plans. Although multilevel analysis is already considered an appropriate method for analyzing healthcare performance data, it has rarely been used to assess case-mix adjustment of such data...

This paper provides practical guidelines for managers and health professionals looking to skill mix as a potential solution to health service delivery problems. These guidelines emphasise the need to evaluate the problem, and examine the context, before deciding if skill mix is the answer. The guidelines are provided in the knowledge that skill mix is rarely examined in a “pure” theoretical sen...
