Abstract: Provided is a method of address resolution in a software-defined network. An Address Resolution Protocol (ARP) request message is received on a network device. The Address Resolution Protocol (ARP) request message from the network device is forwarded to an OpenFlow controller. A determination is made whether the OpenFlow controller includes information to identify a Media Access Control (MAC) address corresponding to an IP address of a receiving device from the Address Resolution Protocol (ARP) request message. A response is generated depending on whether the OpenFlow controller includes said information.

Abstract: Data cleansing and standardization techniques are provided. A user interactively defines rules for cleansing and standardizing data of a source dataset. The rules are applied to the data and varying degrees of results and metrics associated with applying the rules are presented to the user for inspection and analysis.

Abstract: The invention relates to a method and compounds for the preparation of clevidipine butyrate, a very short acting hypertensive calcium antagonist, as well as the synthesis of these compounds useful for the preparation of clevidipine (also known as clevidipine butyrate). Moreover the invention also discloses polymorphic forms of clevidipine butyrate, useful for the preparation of pharmaceutical compositions, and processes to prepare them.

Abstract: The present invention relates to an improved process for the preparation of cis-nucleoside derivative of formula-1 involving chlorination of the compound of formula-2 followed by reaction with compound of formula-3 in presence of a base to get compound of formula-4, reacting the compound of formula-4 with an alkyl halide (RiX) to get a quaternary ammonium salt then with cytosine derivative of formula-5 to provide the compound of formula-6, optionally de-protecting the compound of formula-6 to the compound of formula-7, reducing compound of formula-7 with metal catalyst in presence of a buffer solution, then adding an organic acid to get the compound of formula-8, and converting the compound of formula-8 to cis-nucleoside derivative of formula-1. The present invention further relates to novel cis-nucleoside derivative of formula-8. The present invention also relates to a pharmaceutical composition comprising cis-nucleoside derivative of formula-1 with excipients.

Abstract: A method, apparatus, and article of manufacture is configured to define a structured view of data in a computer system. A relational database management system (RDBMS) stores information in the computer system. As part of a process and framework, a series of business rules and process workflows that manage data (that is hierarchical in nature) that resides in one or more RDBMS tables are maintained. User input is accepted that defines a hierarchical structure that is projected onto the data. The hierarchical structure is stored as metadata in the RDBMS. The hierarchical structure is utilized to graphically visualize, manage, and manipulate the data.

Abstract: Techniques for cross referencing data are presented. A first database object and a second database object are linked together. The linkage is automatically cross referenced to a third database object. Access to any of the database objects can be achieved via any of the remaining database objects and vice versa. Additionally, the link and cross reference can be visualized and visually manipulated and modified.

Abstract: Techniques for managing data relationships are presented. A database element from a first database table is linked with a database element of a second database table via a Graphical User Interface as directed by a user. The link establishes a data relationship having attributes and properties. The relationship along with the attributes and properties are graphically presented to the user for inspection and analysis.

Abstract: A process for producing 4-bromo-2-oxyimino butyric acid, predominantly as the (Z)-isomer of formula (I), wherein R is hydrogen; a linear or branched C1-4 alkyl group; a linear or branched C1-4 alkyl group substituted by a carboxylic acid or an aryl group; a substituted or unsubstituted cyclic alkyl group of 3-6 carbon atoms or a substituted or unsubstituted aryl group. The product is produced by reacting bromine with a 2-(oxyimino)-3-oxo butyric acid derivative of formula (II) wherein R is as defined above and R1 is a tert-butyl group in presence of an organic solvent and in presence of a C1-4 alcohol and acetyl bromide at a temperature ranging from about ?15° C. to about +15° C. Bromine is used in a proportion of about 0.90 to about 1.35 moles per mole of compound (II), preferably 0.90 to 1.10 moles. The acetyl bromide is used in molar proportions of 0.9 to 2 moles per mole of compound (II), preferably 0.9 to 1.5 moles.
