High-Speed Dynamic Programmable Logic Array Chip

This paper describes the circuit design of a programmable logic array chip using four-phase dynamic circuits, operating at a nominal cycle time of 230 nanoseconds. Bootstrap circuit techniques are used to obtain high function and performance by satisfying some special requirements of PLA designs. These include a simple means for two-bit partitioning of the data inputs, a noninverting buffer cir...

Electro-optofluidics: achieving dynamic control on-chip.

A vital element in integrated optofluidics is dynamic tuning and precise control of photonic devices, especially when employing electronic techniques which are challenging to utilize in an aqueous environment. We overcome this challenge by introducing a new platform in which the photonic device is controlled using electro-optical phase tuning. The phase tuning is generated by the thermo-optic e...

As iron goes, so goes disease?

The brain iron overload disorders, collectively known as neurodegeneration with brain iron accumulation (NBIA), would seem to be tantalizing targets for chelation therapy. Efforts to lower brain iron in these disorders date back to the 1960s with deferoxamine mesylate, but systemic iron depletion limited its use. With the advent of chelators better able to specifically relieve central nervous s...

Motivated by recent developments in solid electrolytes based on lithium phosphorous oxynitride (LiPON) materials, we carried out computer simulations in order to develop an understanding of the detailed mechanisms of ionic transport. Starting with crystalline Li3PO4, we investigated some possible structures of isolated defects associated with extrinsic Li ion vacancies and interstitials. In par...
