Abstract:

A single bit line, pulse-operated memory cell. The memory cell includes a first and second inverter, write access and feedback-control transistors, and read access transistor and read buffer transistors. The output of the first inverter is connected to the input of the second inverter and the output of the second inverter is connected to the input of the first inverter through the channel of the feedback-control transistor. The write access and feedback-control transistors are opposite types, and their gates are connected together so that when the feedback control transistor is on the write-access transistor is off and visa versa. Writing the cell thus avoids contending the with the on-transistor of the second inverter. The output of the cell is sensed by the gate of the buffer transistor and coupling the output of the buffer transistor through the read access transistor to the read output line.

Abstract:

Methods and compositions for modulating angiogenesis in a host are provided. In the subject methods, an effective amount of Ca/calcineurin/NF-ATc signaling pathway modulatory agent is administered to the host. In many embodiments, the Ca/calcineurin/NF-ATc signaling pathway modulatory agent is an NF-ATc antagonist, e. g. , in those embodiments of inhibiting angiogenesis. The subject methods find use in a variety of different applications, including the inhibition of tumor growth and the treatment of disease conditions characterized by tumor presence. Also provided are methods of screening for agents that inhibit angiogenesis by modulating the Ca/calcineurin/NF-ATc signaling pathway.

International Classification:

G06K 9/00

US Classification:

382124

Abstract:

A method and system for biometric identification utilizes structured light (e. g. , fine grid) that is projected to the target objects (fingers and palm). The image with structured light on the object contours can give 3D information of the objects with resolution to satisfy NIST fingerprint standard. In embodiments, the structured light can be of different color, to reduce the burden of the software processing. To enhance the capture speed, a model with 2D image on “smooth” 3D surface can be used. In this “2. 5-D” case, the finest feature of the structured light can be as big as millimeter size. Although grid-structured light can satisfy current requirement of fingerprint and palm print capture standards, in other embodiments, a customized structure based on the initial scan result can give optimal result on the 3D data. This may be useful when higher resolution is desired.

US Classification:

438466, 438 22, 438 24

Abstract:

A negative dielectric is induced by the application of a dc bias-electric field in aggregates of oxide nano-particles whose surfaces have been specially treated. The magnitude of the dielectric constant and the frequency where the negative dielectric constant occurs can be adjusted. Such material systems have profound implications in novel devices as well as in science development, e. g. unusual wave propagation, secured communication and ultra-high temperature superconductivity.

438656, 438680, 438685, 257E21168

Abstract:

Methods of improving the uniformity and adhesion of low resistivity tungsten films are provided. Low resistivity tungsten films are formed by exposing the tungsten nucleation layer to a reducing agent in a series of pulses before depositing the tungsten bulk layer. According to various embodiments, the methods involve reducing agent pulses with different flow rates, different pulse times and different interval times.

International Classification:

H01L 21/44

US Classification:

438677, 438685, 257E21575

Abstract:

Methods of forming low resistivity tungsten films with good uniformity and good adhesion to the underlying layer are provided. The methods involve forming a tungsten nucleation layer using a pulsed nucleation layer process at low temperature and then treating the deposited nucleation layer prior to depositing the bulk tungsten fill. The treatment operation lowers resistivity of the deposited tungsten film. In certain embodiments, the depositing the nucleation layer involves a boron-based chemistry in the absence of hydrogen. Also in certain embodiments, the treatment operations involve exposing the nucleation layer to alternating cycles of a reducing agent and a tungsten-containing precursor. The methods are useful for depositing films in high aspect ratio and/or narrow features. The films exhibit low resistivity at narrow line widths and excellent step coverage.
