This paper addresses the search problem in textual inference, where systems need to infer one piece of text from another. A prominent approach to this task is attempts to transform one text into the other through a sequence of inference-preserving transformations, a.k.a. a proof, while estimating the proof’s validity.
There are only three basic constructs in Prolog: facts, rules, and queries. A collection
of facts and rules is called a knowledge base (or a database) and Prolog programming
is all about writing knowledge bases. That is, Prolog programs simply are knowledge
bases, collections of facts and rules which describe some collection of relationships
that we find interesting. So how do we use a Prolog program? By posing queries. That
is, by asking questions about the information stored in the knowledge base...
It is by now well established that quantum machines can
solve certain computational problems much faster than the best algorithms
known in the standard Turing machine model. The complexity
question of which problems can be feasibly computed by quantum machines
has also been extensively investigated in recent years, both in the
context of one machine models (quantum polynomial classes) and various
flavors of multi-machine models (single and multiple prover quantum
Diabetes Mellitus The success of islet cell and pancreas transplantation provides proof of concept for a cell-based approach for type I diabetes. However, the demand for donor pancreata far exceeds the number available, and maintenance of long-term graft survival remains a problem. The search for a renewable source of stem cells capable of regenerating pancreatic islets has therefore been intensive.
Pancreatic βcell turnover occurs in the normal pancreas, although the source of the new βcells is controversial.
In two famous papers , , Fong and Seitz showed that all finite Moufang generalized
polygons were classical or dual classical. In fact, they obtained this result in
group theoretical terms (classifying finite split BN-pairs), but Tits remarked the simple
geometrical translation. And of course, the converse was already well known. In a
search for a synthetic “elementary” proof of the Fong–Seitz result for the specific case
of generalized quadrangles (which is the central and most difficult part in , ),
