摘要： There is provided a catalyst composition having improved hydrothermal stability for the catalytic cracking of a hydrocarbon feedstock to selectively produce propylene. The catalyst composition comprises a first crystalline molecular sieve selected from the group consisting of IM-5, MWW, ITH, FER, MFS, AEL, and AFO and an effective amount of a stabilization metal (copper, zirconium, or mixtures thereof) exchanged into the molecular sieve. The catalyst finds application in the cracking of naphtha and heavy hydrocarbon feedstocks. When used in the catalytic cracking of heavier hydrocarbon feedstocks, the catalyst composition preferably comprises a second molecular sieve having a pore size that is greater than the pore size of the first molecular sieve. The process is carried out by contacting a feedstock containing hydrocarbons having at least 4 carbon atoms is contacted, under catalytic cracking conditions, with the catalyst composition.

摘要： The progress of a endovascular cardiac repair can be monitored by inserting a pressure transducer sensor using a catheter into a chamber of the heart during endovascular repair and then using a small, hand-held read out device to measure pressure easily, safely, inexpensively and accurately. In one aspect a sensor is introduced into the body by the steps of folding or rolling the sensor into a cylinder, loading it into a catheter, and deploying into the heart chamber by allowing it to unroll or unfold, either by itself or facilitated by the incorporation of a super-elastic alloy component.

摘要： We describe an apparatus for learning to predict moves in games such as chess, Go and the like, from historical game records. We obtain a probability distribution over legal moves in a given board configuration. This enables us to provide an automated game playing system, a training tool for players and a move selector/sorter for input to a game tree search system. We use a pattern extraction system to select patterns from historical game records. Our learning algorithm learns a distribution over the values of a move given a board position based on local pattern context. In another embodiment we use an Independent Bernoulli model whereby we assume each moved is played independently of other available moves.

摘要： A stent constructed using elements containing micro-mechanical latching mechanisms is disclosed. The micro-mechanical latching elements allow sliding motion between two surfaces in one direction, and restrict sliding motion in the opposite direction. The micro-mechanical latch surface features are formed using microelectronic mechanical systems (MEMS) manufacturing methods. The male surface of the latching components contains an array of ridges or protrusions, and the receiving surface contains a matching array of recesses. The array of ridges or protrusions and the corresponding recesses have uniformly dissimilar slopes that result in a substantially greater frictional force in one direction than in the opposite direction. The separation distance between the two surfaces is such that the male latch surface is engaged with the receiving surface recesses in the low stress “locked” state, preventing motion in the undesired direction.

摘要： In accordance with various embodiments of the invention, an apparatus is provided for hybridizing a nucleic acid microarray immobilized on a surface of a solid substrate. The apparatus comprises at least one assembly for securing the solid substrate during hybridization, the assembly comprising a carrier and a cover having a surface facing the carrier. The carrier and the cover can be dimensioned to receive the solid substrate between the carrier and the surface of the cover so that the surfaces of the cover and the solid substrate define a cavity. In some embodiments, the apparatus can include a fluid control module comprising a manifold, at least one liquid reservoir, at least one waste container, and a vacuum source in fluid communication with the waste container. The manifold can provide fluid communication between the liquid reservoir and the cavity and between the cavity and the waste container, and the vacuum source can provide a pressure difference between the liquid reservoir and the waste container. The apparatus can further include at least one thermal management module for controlling temperature of the nucleic acid microarray immobilized on the surface of the solid substrate, and the thermal management module thermally can contact the assembly; and a pulse valve in fluid communication with the cavity, the pulse valve adapted to agitate fluid within the cavity.
