Abstract: The present disclosure provides an information display method, which can be applied to a display server. An example method includes obtaining at least two sub-pictures, original position information and first current position information of each sub-picture in a picture. The at least two reordered sub-pictures, and first current position information of the at least two reordered sub-pictures are transmitted to a social application client. Second current position information about all of or some of the at least two sub-pictures is received from the social application client. It is determined whether second current position of each sub-picture is the same as the original position, and if yes, interactive information about information displayed by the picture is transmitted to the social application client. The present disclosure also provides a corresponding display server and social application client.

Abstract: The present disclosure provides an information-presentation-item display method for a multimedia playback device connected to a server. The method includes: playing a first content; playing an information-presentation-item, different from the first content, provided by the server; receiving a confirmation instruction sent by a remote-control device bound to the multimedia playback device; displaying, according to the confirmation instruction, description information related to the information-presentation-item, the description information including a display graphic code; and displaying first extension information related to the information-presentation-item after it is confirmed that the graphic code is scanned based on a graphic code link corresponding to the graphic code received by the server, the first extension information being information for extending content in the description information.

Abstract: A virtualization method for large-scale distributed heterogeneous data includes using a three-layer structure and a two-level mapping. According to different abstraction degrees, a data model is defined as three layers from low to high: a physical layer, a virtual table layer, and a virtual view layer. Each layer has a proprietary data model. The two-level mapping comprises a PV mapping and a VV mapping, which is a transformation mechanism of the data models of different layers. As a result, the virtualization method virtualizes decentralized heterogeneous data, and is applicable to data interoperability treatments.

Abstract: Computing device, computer instructions and method for determining an image of a surveyed subsurface. The method includes receiving recorded wave fields D recorded with seismic sensors over the subsurface; generating a series of modified recorded wave fields Dn based on the recorded wave fields D; iteratively applying an objective function Fi to (1) one element Di of the series of modified recorded wave fields Dn and (2) predicted wave fields Pmi, where “i” is an index associated with a given iteration; calculating with a computing device an updated velocity model mi+1 based on a previous velocity model mi and a step length; and producing the image of the subsurface based on the recorded wave fields D and the updated velocity model mi+1. The predicted wave fields Pmi are predicted by the previous velocity model mi.

Abstract: Content transfer involving a gesture is described. In an implementation, a method is implemented by a mobile communications device that includes recognizing a gesture input via a touchscreen of the mobile communications device that is indicative of a direction, the touchscreen including a display of content. One or more other mobile communications devices are located that are positioned, approximately, along the indicated direction of the gesture. A communication is formed to transfer the content to the located one or more other mobile communications devices.

Abstract: An apparatus having a first circuit and a second circuit. The first circuit may be configured to buffer an input signal received as a single-ended signal from a data bus connected between a memory channel and a memory controller. The second circuit may be configured to condition the input signal relative to a reference voltage to generate a differential signal. The reference voltage may be isolated from the second circuit in response to a transition from a power down condition to a power on condition.

Abstract: An apparatus includes a first circuit, a second circuit, and a third circuit. The first circuit may be configured to (i) reduce a current value in a sequence of input values that have been carried on a single-ended line of a data bus coupled to a memory channel to generate a version of the current value, and (ii) reduce a first reference voltage to generate a second reference voltage. The second circuit may be configured to slice the current value with respect to the first reference voltage to generate a first intermediate value. The third circuit may be configured to slice the version of the current value with respect to the second reference voltage to generate a second intermediate value. The first intermediate value and the second intermediate value generally define a sliced value of the current value.

The first circuit may be configured to (i) receive a sequence of input values that have been carried on a single-ended line of a data bus coupled to a memory channel, (ii) slice a previous input value of said sequence of input values to generate a previous output value, (iii) slice a current input value of said sequence of input values to generate a current output value, and (iv) present said current output value on a differential line. The previous input value generally precedes said current input value in said sequence of input values. The second circuit may be configured to decode said previous input value based on a tap coefficient value to generate a plurality of feedback values suitable to reduce an inter-symbol interference in said current input value caused by said previous input value.

Abstract: In a database accessing method using an electronic device having a database, character fields and corresponding attributes are predefined. An entity object including the character fields is generated and provided to a client device for inputting business data. After receiving an encapsulated entity object from the client device, the business data including selected character fields, corresponding character data, and an operation request for the database are acquired. When the database includes a data table and the data table includes the character fields corresponding to the selected character fields, the selected character fields and the character data of the selected character fields are verified. When the selected character fields and the character data of the selected character fields are valid, character data of the character fields corresponding to the selected character fields are updated using the character data of the selected character fields according to the operation request.
