Abstract:
Described herein are systems and methods for quantitatively measuring manganese ion efflux in a subject. In general, the systems and methods compare imaging data from a subject taken over specific periods of time to pharmacokinetic models in order to measure manganese ion efflux rates from an organ in a subject. By understanding the specific location and rate of manganese ion efflux and influx from the organ, it is possible to more accurately correlate calcium ion activity. Calcium ion efflux is associated with a number of biological mechanisms in the subject, and the methods and systems described herein can be used as a diagnostic tool not only for monitoring calcium efflux in the subject but also aid in the treatment of diseases associated with changes in calcium ion efflux.

An apparatus for fabricating IB-IIIA-VIA2 compound semiconductor thin films is provided, including a reaction chamber, a pressure control unit connected with the reaction chamber, a pedestal disposed in the reaction chamber wherein the at least one substrate includes elements of group IB and group IIIA, a first group VIA element supply unit connecting with the reaction chamber for providing vaporized first group VIA elements into the reaction chamber, and a plasma unit disposed in the reaction chamber. In one embodiment, during a reaction in the reaction chamber, the vaporized first group VIA elements flow through the high density plasma region and transform into ionized first group VIA elements, and the ionized first group VIA elements diffuse into the at least one substrate comprising elements of group IB and group IIIA to form a IB-IIIA-VIA2 compound semiconductor thin film thereover.
Abstract:
A valve stem with an adjustable tire pressure detector has a tire pressure detector, a valve stem body, a conducting member and a fastening assembly. The tire pressure detector has a guiding slot, a concave surface and a convex surface. The guiding slot is formed through the tire pressure detector and forms two openings. The concave surface and the convex surface are formed on the tire pressure detector respectively adjacent to the openings. The valve stem body is moveably mounted through the guiding slot and has a head being moveably mounted on the concave surface. The conducting member is mounted on the concave surface or the convex surface and is electrically contacted to the valve stem body and the tire pressure detector. The fastening assembly mounts the valve stem body on a rim securely.

A semiconductor gate structure is described, which comprises a substrate, a gate oxide positioned on the substrate, a first conductive layer positioned on the gate oxide and a second conductive layer positioned on the first conductive layer. The second conductive layer comprises a bottom portion positioned on the first conductive layer, and an upper portion positioned on the bottom portion. The width of the bottom portion is equal to that of the first conductive layer, and one side of the upper portion is aligned to one side of the bottom potion, wherein the other side of the upper portion possesses at least a lateral concave. A bit-line contact metal is subsequently formed next to the concave.
Abstract:
A carbon nanotube substrate structure including a substrate and a conductive layer disposed thereon. The carbon nanotube layer or the conductive layer has numerous support particles with a diameter smaller than the length of the carbon nanotube of the carbon nanotube layer. The carbon nanotubes, the conductive layer and the support particles are adhered to each other by means of a glue. The carbon nanotubes lean on the support particles, whereby the carbon nanotubes can stand and protrude from the surface of the carbon nanotube layer to serve as field emission sources.
Abstract:
A method of fabricating a buried contact in a static random access memory. A gate oxide layer, a first conducting layer and a masking layer are formed sequentially on a substrate. A buried contact opening is formed inside the gate oxide layer, the first conducting layer and the masking layer, which opening exposes a part of the substrate. An epitaxial layer is formed inside the buried contact opening, which epitaxial layer fills up the buried contact opening. After the masking layer is removed, a second conducting layer is formed above the substrate. A buried contact is formed in the substrate that is below the epitaxial layer. The gate oxide layer, the first conducting layer, the epitaxial layer and second conducting layer are patterned to expose a part of the substrate and a part of the buried contact. A source/drain is formed in the substrate and a part of the source/drain is mixed with a part of the buried contact.
Abstract:
Although the spacers are formed on the sidewalls of gate electrode and words lines via the same steps of deposition and etch-back processes, only the spacers disposed at the sidewalls of the gate electrode are practical for fabricating peripheral devices with LDD structure, and such fabrication is impractical in the memory cell region. On the contrary, the region beneath the spacers disposed at the sidewalls of word lines will become the path through which leakage current flows. The present invention makes use a shielding layer to cover the second active region as a masking, and then removes the spacers disposed at the sidewalls of word lines. Afterwards, isolating regions are formed through one implantation procedure to thereby decrease leakage current and simplify the process flow.
Abstract:
A computer program management system having a first memory device containing firmware, a shadow processing device for copying the firmware from the first memory device to a shadow region of a system memory device, a cache RAM, and a flush device. Firmware is copied from the shadow region of the system memory device to the cache RAM for execution by the CPU. If an attempt is made to write to the shadow region of the system memory device, the flush device causes the CPU to flush the contents of the cache RAM.Alternatively, the system may have a first memory device containing firmware, a shadow processing device for copying the firmware from the first memory device to a shadow region of a system memory device, a cache RAM, and a disabling device. In this embodiment of an attempt is made to write to the shadow region of the system memory device, the disabling device causes the CPU to prevent the data from being written to the cache RAM.
