Jan 12, 2006

Appl. No.:

11/330936

Inventors:

Tao Li - Scotch Plains NJ, US
Maria Tamarez - Rahway NJ, US
Aleksey Zaks - Hoboken NJ, US

International Classification:

C12P 7/62
C07C 69/74

US Classification:

435135000, 560128000

Abstract:

This application discloses a novel process for the conversion of a series of racemic propargylic alcohols to corresponding (R)-enantiomers. The application also discloses the enantio-selective esterification of a propargylic alcohol from its racemate to prepare an (R)-ester. Enantioselectivity is enhanced by the use of experimentally determined enzymes. The propargylic alcohols and chiral esters may be useful in preparing compounds such as, for example, thrombin receptor antagonists. Among the synthetic pathways disclosed is the following:

Abstract:

A method for determining, from a document, an answer to a query using a query answering system, comprising: (i) encoding, using an encoder, one or more documents; (ii) encoding a received query; (iii) generating, using an attention mechanism, a query-aware document representation comprising alignment between one or more words in one of the plurality of documents and one or more words in the query; (iv) generating, using a hierarchical self-attention mechanism, a word-to-sentence alignment of the query-aware document representation; (v) labeling, using a conditional random field classifier, each of a plurality of words in the word-to-sentence alignment with one of a one of a plurality of different sequence identifiers, resulting in possible labeled answering spans; and (vi) generating, from the one or more possible labeled answering spans, a response to the query.

Abstract:

An example particle therapy system includes: a synchrocyclotron to output a particle beam; a magnet to affect a direction of the particle beam to scan the particle beam across at least part of an irradiation target; scattering material that is configurable to change a spot size of the particle beam, where the scattering material is down-beam of the magnet relative to the synchrocyclotron; and a degrader to change an energy of the beam prior to output of the particle beam to the irradiation target, where the degrader is down-beam of the scattering material relative to the synchrocyclotron.
