Knowledge Provenance: An Approach to Modeling and Maintaining The Evolution and Validity of Knowledge Jingwei Huang Ph.D. Graduate Department of Mechanical and Industrial Engineering University of Toronto 2008 TheWeb has become an open decentralized global information / knowledge repository, a platform for distributed computing and global electronic markets, where people are confronted with inf...

Theorem 2 is the main result in this note. Lemma 1 is key to our main result. It is different from the result in [2] because it does not restrict the number of terms in the partial sum to an even one. Also, our inequalities (2) should be compared with the corresponding result in [2] for k = 2. Lemma 1. Let sn(p) be the nth partial sum of the p-series ∑∞ i=1(1/i), and let k be any integer greate...

We propose the first Key-policy Attribute-based Encryption (KP-ABE) scheme for (monotone) Boolean circuits based on bilinear maps. The construction is based on secret sharing and just one bilinear map, and can be viewed as an extension of the KP-ABE scheme in [7]. Selective security of the proposed scheme in the standard model is proved, and comparisons with the scheme in [5] based on leveled m...

Our previously conducted pharmacological screening led as to the discovery of the strong local anesthetic activity of the compound designated as KP-23. Earlier crystallographic studies revealed that the compound KP-23 crystallized in diastereoisomeric form in lowest symmetry. The aim of these comparative investigations was to evaluate anesthetic activity of KP-23 and its R,S-diastereoisomers, w...

Consecutive non-replicate clinical isolates (n=191) of carbapenem non-susceptible Enterobacteriaceae were collected from 21 hospital laboratories across Italy from November 2013 to April 2014 as part of the European Survey on Carbapenemase-producing Enterobacteriaceae (EuSCAPE) project. Klebsiella pneumonia carbapenemase-producing K. pneumoniae (KPC-KP) represented 178 (93%) isolates with 76 (4...

Activation of the kynurenine pathway (KP) of tryptophan metabolism results from chronic inflammation and is known to exacerbate progression of neurodegenerative disease. To gain insights into the links between inflammation, the KP and multiple sclerosis (MS) pathogenesis, we investigated the KP metabolomics profile of MS patients. Most significantly, we found aberrant levels of two key KP metab...

TNP, a company in cargo transportation and logistics, is grappling with challenges such as high employee turnover struggles to meet performance goals, both on an individual team level. The company’s rate exceeds its target, the overall Key Performance Indicator (KPI) achievement by High-Level Management remains below standard of 80%. This study aims improve situation analysing current KPI frame...

Transdermal patches loaded with pravastatin was previously characterized in another published study by Serrano-Castañeda et al; 2015. These transdermal patches (TP) were generated by the plate casting technique, the in vitro percutaneous absorption studies of TP were evaluated for three different formulations of TP with different quantities of Pluronic F-127 (PF-127): i) without PF-127 (TP W), ...
