An improved optical photolithography system and method provides predetermined light patterns generated by a direct write system without the use of photomasks. The Direct Write System provides predetermined light patterns projected on the surface of a substrate (e.g., a wafer) by using a computer controlled component for dynamically generating the predetermined light pattern, e.g., a spatial light modulator. Image patterns are stored in a computer and through electronic control of the spatial light modulator directly illuminate the wafer to define a portion of the polymer array, rather than being defined by a pattern on a photomask. Thus, in the Direct Write System each pixel is illuminated with an optical beam of suitable intensity and the imaging (printing) of an individual feature is determined by computer control of the spatial light modulator at each photolithographic step without the use of a photomask. The Direct Write System including a spatial light modulator is particularly useful in the synthesis of DNA arrays and provides an efficient element for polymer array synthesis by using spatial light modulators to generate a predetermined light pattern that defines the image patterns of a polymer array to be deprotected.

A method and apparatus for imaging a sample are provided. An electromagnetic radiation source generates excitation radiation which is sized by excitation optics to a line. The line is directed at a sample resting on a support and excites a plurality of regions on the sample. Collection optics collect response radiation reflected from the sample I and image the reflected radiation. A detector senses the reflected radiation and is positioned to permit discrimination between radiation reflected from a certain focal plane in the sample and certain other planes within the sample.

The invention involves a pressurized package containing an aqueous latex paint which is discharged from a collapsible piston within the pressurized container by the action of a propellant under pressure, and wherein the stream of paint discharging upon opening of the valve of the container is broken up by a mechanical breaker before being discharged through the nozzle in the form of a fine spray or mist devoid of propellant. Means are provided in the form of a cap for the nozzle for reducing or substantially eliminating the space about the nozzle after use of portions of the contents of the package to prevent drying out of any paint adhering to the nozzle and thereby clogging the nozzle. The paint employed is an aqueous acrylic latex emulsion paint in which the pigment content ranges from 2% to 15%.

A latex aerosol paint composition having a total solids content of less than 40%, a viscosity of from 10 to 60 seconds measured on the No. 4 Ford cup, a pigment content of from 2 to 15%, is dispensed from an aerosol container having a mechanical break-up valve utilizing nitrogen or air as the propellant. The ratio by volume of the compressed nitrogen or air at a pressure of 100 psi at 70.degree. F to the volume of the paint composition is from 60:40 to 50:50. In the preferred embodiment, the volume ratio of the nitrogen to the paint formulation is 60:40. The solids content may be as low as 30%, and the viscosity of the paint formulation is from 15 to 30 seconds on the No. 4 Ford cup. It is preferred that the average particle size range of the pigment be from 0.2 to 0.3 microns.
摘要:
A method for matching production history to flow simulations includes identifying a plurality of parameters that control an objective function measuring the mismatch between a flow simulation response in a parameter subspace and a production history. A value is calculated for an objective function and for a static measurement at each of a plurality of experiments in the parameter subspace. These results are used to develop a mathematical relationship between one or more static measurements and the objective function. During subsequent adjustment of the simulation model, a target window in the objective function is identified, and flow simulations are performed for each modified model that is predicted from the static geologic measurement to produce an objective function within the window. An objective function of each flow simulation to the production history is calculated and the procedure is iterated until the objective function is within a target range.

One or more techniques and/or systems are disclosed for predicting propagation of a message on a social network. A predictive model is trained to determine a probability of propagation of information on the social network using both positive and negative information propagation feedback, which may be collected while monitoring the social network over a desired period of time for information propagation. A particular message can be input to the predictive model, which can determine a probability of propagation of the message on the social network, such as how many connections may receive at least a portion of the message and/or a likelihood of at least a portion of the message reaching respective connections in the social network.
摘要:
Many computing scenarios involve the classification of content items within one or more categories. The content item set may be too large for humans to classify, but an automated classifier (e.g., an artificial neural network) may not be able to classify all content items with acceptable accuracy. Instead, the automated classifier may calculate a classification confidence while classifying respective content items. Content items having a low classification confidence may be sent to a human classifier, and may be added, along with the categories identified by the human classifier, to a training set. The automated classifier may then be retrained using the training set, thereby incrementally improving the classification confidence of the automated classifier while conserving the involvement of human classifiers. Additionally, human classifiers may be rewarded for classifying the content items, and the costs of such rewards may be considered while selecting content items for the training set.
