Appl. No.:

10/352658

Inventors:

Yu Li - Sunnyvale CA

Mark W. Randolph - San Jose CA

Assignee:

Advanced Micro Devices, Inc. - Sunnyvale CA

International Classification:

H01L 29788

US Classification:

257315, 257285

Abstract:

An array of non-volatile memory cells is provided for storing a data pattern and reproducing the data pattern. The array comprises a semiconductor substrate moderately doped with a first type of impurity to enhance conductivity. A plurality of bit lines within the substrate define a plurality of vertical channel regions spaced there between. Each bit line comprises the substrate doped with a second type of impurity to enhance conductivity. Each channel comprises a moderately doped channel region portion adjacent to a first one of the bit lines and a slightly more heavily doped channel region portion adjacent to a second one of the bit lines. A plurality of parallel spaced apart semiconductor word lines are positioned over the substrate and separated from the substrate by an insulator film, a charge storage region, and a second insulator film. An array control circuit is coupled to each bit line and each word line to provide a drain bit line programming potential the second one of the bit line diffusions to accelerating electrons from the first one of the bit line diffusions towards the second one of the bit line diffusions and to provide a word line programming potential to a selected one of the word lines to divert the accelerated electrons from the channel region beneath the selected word line across the insulator film into the charge storage region.

US Classification:

536 231, 5303871

Abstract:

The present invention relates to a new molecular pathway in which activation of the receptor-interacting protein (RIP, a serine-threonine kinase) and Jun N-terminal kinase induce cell death with the morphology of autophagy. Further, autophagic death is induced by caspase 8 inhibition and expression of the mammalian genes ATG7 and beclin.

International Classification:

C12Q 1/34

US Classification:

435018000

Abstract:

This invention relates to a method for assessing risk of Coronary Vascular Disease (CVD). Specifically, it relates to utilizing risk assessment from both Lipoprotein Associated Phospholipase A2 (Lp-PLA2) and C-reactive protein (CRP) in combination. In addition the invention relates to a method for assessing risk of Coronary Vascular Disease (CVD) in a patient with low to normal Low Density Lipoprotein Cholesterol (LDL) levels utilizing both LDL and Lipoprotein Associated Phospholipase A2 (Lp-PLA2). Moreover, the invention relates to the use of risk associated with Lp-PLA2, CRP and LDL in combination and specific ranges thereof to predict Coronary Vascular Disease.

International Classification:

G06F 17/30

US Classification:

707737, 707E17005

Abstract:

Methods and apparatus are described for collecting and storing large volumes of time series data. For example, such data may comprise metrics gathered from one or more large-scale computing clusters over time. Data are gathered from resources which define aspects of interest in the clusters, such as nodes serving web traffic. The time series data are aggregated into sampling intervals, which measure data points from a resource at successive periods of time. These data points are organized in a database according to the resource and sampling interval. Profiles may also be used to further organize data by the types of metrics gathered. Data are kept in the database during a retention period, after which they may be purged. Each sampling interval may define a different retention period, allowing operating records to stretch far back in time while respecting storage constraints.
