This paper focuses on mining the hyponymy (or is-a) relation from large-scale, open-domain web documents. A nonlinear probabilistic model is exploited to model the correlation between sentences in the aggregation of pattern matching results. Based on the model, we design a set of evidence combination and propagation algorithms.
On 23 March 1989, electrochemists M. Fleischmann and S. Pons claimed in a press conference at the University of Utah that they had achieved nuclear fusion in a tabletop chemistry experiment. Since then, evidence of fusion in what is now called low-energy nuclear reaction (LENR) research has grown only slightly stronger. Their hypothesis that a novel form of thermonuclear fusion was responsible for their experimental results is still unproved.
Data fusion is a research area that is growing rapidly due to the fact that it provides
means for combining pieces of information coming from different sources/sensors, resulting
in ameliorated overall system performance (improved decision making, increased detection
capabilities, diminished number of false alarms, improved reliability in various situations at
hand) with respect to separate sensors/sources.
The transmembrane topology of presenilins is still the subject of debate
despite many experimental topology studies using antibodies or gene
fusions. The results from these studies are partly contradictory and conse-quently several topology models have been proposed. Studies of preseni-lin-interacting proteins have produced further contradiction, primarily
regarding the location of the C-terminus.
A eukaryotic-type protein serine/threonine kinase, PknA, was cloned from Mycobacterium tuberculosis strain H37Ra. Sequencing of the clone indicated 100% identity with the published pknA sequence of M. tuberculosis strain H37Rv. PknA fused to maltose-binding protein was expressed in Escherichia coli; it exhibited a molecular mass of % 97 kDa. The fusion protein was puriﬁed from the soluble fraction by aﬃnity chromatography using amylose resin.
Phylogenetic evidence is presented that primitively amito-chondriate eukaryotes containing the nucleus, cytoskele-ton, and endomembrane system may have never existed.
Instead, the primary host for the mitochondrial progeni-tor may have been a chimeric prokaryote, created by
fusion between an archaebacterium and a eubacterium, in
which eubacterial energy metabolism (glycolysis and
fermentation) was retained.
