Abstract: Administration of sPLA2 inhibitors in combination with statins has been found to reduce major adverse cardiac events (MACEs), inflammatory biomarker levels, and LDL-C levels in subjects who have recently experienced an index ACS  event to a significantly greater degree than statins alone. These results were unexpected given previous results showing that statins alone are insufficient to satisfactorily reduce MACEs and inflammation in this high-risk population. Therefore, provided herein are methods of treating MACEs, treating ACS, inhibiting inflammation, and lowering cholesterol levels in a subject who has pre-viously experienced an ACS event by administering one or more sPLA2 inhibitors alone or in combination with one or more statins.

The lid achieves this without requiring removal of the lid while also providing an impeded foodstuff dispense path having greater control. The cover pivots between open and closed positions, and in one form, can be secured in one or both positions. This can be achieved by releasably securing the cover to the top wall to hold the cover in the closed position and/or capturing a tab of the cover within a depression in an edge portion of the lid to hold the cover in the open position. The cover can further be integrally attached to the lid so that the cover is generally coplanar with the top wall when in the closed position.

IPC: C01B31/02
Filed: 2010-06-11
Abstract: In various embodiments, the present disclosure describes processes for preparing functionalized graphene nanoribbons from carbon nanotubes. In general, the processes include exposing a plurality of carbon nanotubes to an alkali metal source in the absence of a solvent and thereafter adding an electrophile to form functionalized graphene nanoribbons. Exposing the carbon nanotubes to an alkali metal source in the absence of a solvent, generally while being heated, results in opening of the carbon nanotubes substantially parallel to their longitudinal axis, which may occur in a spiralwise manner in an embodiment. The graphene nanoribbons of the present disclosure are functionalized on at least their edges and are substantially defect free. As a result, the functionalized graphene nanoribbons described herein display a very high electrical conductivity that is comparable to that of mechanically exfoliated graphene.

Title: System and method for identifying multiple paths between network nodes
Inventor: ZHOU JUNLAN
IPC: H04L45/128
Filed: 2010-07-29
Abstract: Aspects of the invention pertain to transmitting packet data across a computer network (200). The packets may be sent via one or more distinct routes (208, 210) from a source to a destination. Each route may employ multiple routers (206) disposed along the network. Non-colliding routes are determined by transmitting pairs of probe packets along the routes. A first probe packet (P1) has a maximal length, and a second probe packet (P2) has a minimal length. Depending on the order of arrival of the probe packets, the system determines whether two transport layer ports at the destination device collide (306). If there is a collision, then the system (202, 206) searches for a set of non-colliding ports (308). Once the non-colliding ports are determined, application data may be sent as packets along the different routes to those ports.

Title: A method and system for multiple dataset gaussian process modeling
Inventor: VASUDEVAN SHRIHARI
IPC: G06F17/17
Filed: 2010-09-15
Abstract: A method of computerised data analysis and synthesis is described. First and second datasets of a quantity of interest are stored. A Gaussian process model is generated using the first and second datasets to compute optimized kernel and noise hyperparameters. The Gaussian process model is applied using the stored first and second datasets and hyperparameters to perform Gaussian process regression to compute estimates of unknown values of the quantity of interest. The resulting computed estimates of the quantity of interest result from a non-parametric Gaussian process fusion of the first and second measurement datasets. The first and second datasets may be derived from the same or different measurement sensors. Different sensors may have different noise and/or other characteristics.
