摘要： The invention involves a die having domino circuits. In some embodiments, at least some of the domino circuits include an output stage and a domino stage including a domino stage output node coupled to the output stage. The domino stage includes a wide-fanin evaluate network including the domino stage output node and at least one intermediate node. The domino stage has improved noise immunity and reduced leakage through reverse body biasing transistors in the evaluate network by raising voltage of the at least one intermediate node without static power consumption through the evaluate network. In other embodiments, at least some of the domino circuits include an output stage and a domino stage including a domino stage output node coupled to the output stage. The domino stage includes a wide-fanin evaluate network including the domino stage output node and wherein the domino stage further includes a diode transistor having a gate and an additional terminal connected to the domino stage output node. The diode transistor may resist leakage by operating in a subthreshold region to replenish charge on the domino stage output node and resists noise by turning on when small amounts of noise barely turn on transistors of the evaluate network.

摘要： The present invention provides methods for enhancing the efficiency of cell electroporation using dielectrophoresis-assisted cell localization and uses thereof in a microfluidic biochip system. Cells are first subject to dielectrophoresis and localized to regions where the electric field intensity is high enough to render cells electroporated. The invention enhances the efficiency of in situ cell electroporation on a traditional microfluidic biochip.

摘要： Systems and methods for characterizing a spatial frequency of interface regions within a subterranean formation. A first method may include drilling a wellbore with a drilling assembly and measuring a downhole parameter during the drilling. The downhole parameter may be indicative of a lithology of a portion of the subterranean formation that is proximal to the drilling assembly. The first method also may include calculating an information entropy of the downhole parameter and characterizing the spatial frequency of the interface regions based upon the information entropy. A second method may include calculating the information entropy as a function of distance within a first wellbore and characterizing the spatial frequency of the interface regions. The second method also may include drilling a second wellbore within the subterranean formation and regulating the drilling based upon the spatial frequency of the interface regions. The systems include systems that perform the methods.

摘要： A user is provisioned for a Web service by supplying a user name and password. A digital certificate and VPN identifier are generated and downloaded to the user's computer. The VPN identifier and user identifier are stored into a database. The user accesses the Web service and establishes a VPN using the certificate and VPN identifier. A user identifier, user name or user password is not required. A gateway computer uses the VPN identifier to access the database previously established during the provisioning session to retrieve the user identifier. Retrieval of the user identifier validates that the computing device is authorized to use the Web service. The gateway computer stores the client IP address and a mapping to the user identifier into a database. A proxy server retrieves the user identifier from the database using the IP address and includes the user identifier in Web traffic for a remote computer.

摘要： An indirect interaction input device, such as but not limited to a touch sensor, can provide multiple points of input, such as two or more positions in a coordinate space where a user is touching the sensor. These multiple points are in turn mapped to multiple positions on an output device such as a display. The mapping can be relative or absolute. With a relative mapping, boundary conditions for single and multiple displays are applied and, if appropriate, remedial offsets are added to the input points to maintain a desired user interaction model.
