Disclosed are compositions and methods for amplification of nucleic acid sequences of interest. It has been discovered that amplification reactions can produce amplification products of high quality, such as low amplification bias, if performed on an amount of nucleic acid at or over a threshold amount and/or on nucleic acids at or below a threshold concentration. The threshold amount and concentration can vary depending on the nature and source of the nucleic acids to be amplified and the type of amplification reaction employed. Disclosed is a method of determining the threshold amount and/or threshold concentration of nucleic acids that can be used with nucleic acid samples of interest in amplification reactions of interest. Because amplification reactions can produce high quality amplification products, such as low bias amplification products, below the threshold amount and/or concentration of nucleic acid, such below-threshold amounts and/or concentrations can be used in amplification reactions.

The invention relates to a display system which comprises a display screen (101) for displaying a graphical representation. The surface of the display screen has relief (103, 104) in order to provide tactile and/or visual guidance to the user. The display system according to the invention comprises a relief generator for dynamically generating the relief (103, 104) on the display screen. It is thus achieved that the relief can be changed dynamically in accordance with the graphical output of the current application.

A method is described for navigating in the interior of the body using three-dimensionally visualized structures. In a first step of the method, at least two two-dimensional images of the same anatomical object are provided from different perspectives, and also items of information that make it possible to draw conclusions about the respective spatial position of an imaging system relative to the anatomical object. The projections of a geometrical structure to be visualized are then created in every two-dimensional image, wherein a geometrical structure to be visualized is created in each two-dimensional image, wherein the geometrical structure to be visualized is different from the anatomical object. A cone surface is then generated in space for each image wherein the spatial positions of the cone vertex and cone directrix are determined from the respective spatial position of the imaging system and the shape of the cone directrix is determined from the shape of the projection of the geometrical structure to be visualized on the image. Finally, a spatial intersection of the individual cone surfaces is formed to determine the geometrical structure and the geometrical structure determined and/or an intersection of a plurality of geometrical structures determined are/is represented and the representation is used for navigation.

A pixel circuit in an organic light emitting device capable of realizing high gradation representation by self-compensating a threshold voltage, and a method for driving the same. The pixel circuit includes an electroluminescent element for emitting light in response to an applied driving current. A first transistor delivers a data signal voltage in response to a current scan line signal. A second transistor generates a driving current to drive the electroluminescent element in response to the data signal voltage. A third transistor connects the second transistor in the form of a diode in response to a current scan signal to self-compensate the threshold voltage of the second transistor. A capacitor stores the data signal voltage delivered to the second transistor. A fourth transistor delivers a power supply voltage to the second transistor in response to a current light-emitting signal. A fifth transistor provides the driving current, provided from the second transistor, for the electroluminescent element in response to the current light-emitting signal.

The method includes the steps of determining the image text objects in each of a plurality of frames of the video image sequence; comparing the image text objects in each of the plurality of frames of the video image sequence to obtain a record of frame sequences having matching image text objects; extracting the content for each of the similar image text objects in text string format; and storing the text string for each image text object as a video text object in a retrievable medium.

System and method for the indexing and retrieval of semantically annotated information units from a collection of semantically annotated indexed information units in response to a query using an ontology-based IR model. The retrieval method comprises: receiving a semantically annotated query with semantic annotations to individuals or classes within a determined populated base ontology; embedding, as a set of weighted-mentions to individuals or classes within the populated base ontology, the semantically annotated query in a semantic representation space of an ontology-based metric space IR model; obtaining the representation in the semantic representation space for every indexed information unit; computing the Hausdorff distance between the space representation of the query and the space representation of all the indexed information units of the collection; retrieving and ranking, the relevant information units based on the computed Hausdorff distance.

The invention includes a method and system to provide a competitive pricing tool so that automobile dealers can more efficiently and effectively price their used vehicles. The system achieves the optimal sales price by obtaining the relevant pricing and mileage of vehicles for sale that are similarly situated to the focus vehicle. Once the information is obtained, the system creates a value ranking for each of the vehicles for sale and for the focus vehicle. The user is then able to revise the focus vehicle pricing to determine the optimal sales price. The invention also provides information to the potential customer about the vehicle for sale, including information relating to other similar vehicles for sale in a particular geographical area that can be accessed at the point of sale, or by the customer at a later time and place. The party offering the product for sale is informed each time the customer accesses the information, thereby indicating the level of interest by the customer. The invention further provides a stocking tool to determine when to purchase additional vehicles for inventory, a merchandising view to review and revise advertisements, and an automatic description generator for the particular vehicle being sold.

A method of generating a real time control signal for use in an electric arc welding process having welding voltage and welding current, said method comprising: measuring the welding voltage and welding current at a first time, momentarily changing either the welding voltage or welding current by less than about 10%, then measuring the welding voltage and the welding current after the change at a second time, determining the welding voltage difference between the first time and the second time, determining the welding current difference between the first time and the second time, producing a derivative value representing the desired control signal by dividing the welding voltage difference between the first and second times by the welding current difference between the first and second times and generating the control signal by the derivative value.

A method for forming a prograde kinematic model allowing reproduction in 3D intermediate geometries of geologic objects of an underground zone such as a sedimentary basin, from an initial state to a current state. A representation of the current geometry of the geologic objects of the zone is formed by interpretation of acquired data obtained by seismic exploration, by in-situ measurements and by observations, then each geologic object is subdivided into layers separated by deformation interfaces. Each one of the layers is defined by means of a grid pattern into a series of hexahedral volume elements. Tectonic deformations are then applied separately and successively to each series of volume elements of a layer in relation to an underlying layer while conserving the thickness and the surface area of an intermediate neutral surface in each volume element. Then the tectonic deformations are iteratively modified until a geologic representation substantially in accordance with the known final state of the underground zone is obtained.
