Computing based on biochemical processes is a newest rapidly developing field of unconventional information and signal processing. In this paper we present results of our research in the field of biochemical computing and summarize the obtained numerical and experimental data for implementations of the standard two-input OR and AND gates with double-sigmoid shape of the output signal. This form...

A heteroditopic BODIPY dye that performs all basic Boolean operations with a cation (K(+)) and an anion (F(-)) as inputs and absorption, transmission and fluorescence as outputs is described. The molecular logic gate can also act as a digital comparator between the inputs.

The paper analyses various proposals for the organization of regional electricity transmission in terms of the market incompleteness that they may implicitly assume. Elementary notions of variational inequalities constitute the analytical tool used throughout the paper. The discussion is conducted with reference to the flow gate debate in California and European proposals for the organization o...

We review recent advances in aberration-corrected scanning transmission electron microscopy that allow sub-Ångstrom beams to be used for imaging and spectroscopy, with enormous improvement in sensitivity for single atom detection and the investigation of interfacial electronic structure. Comparison is made between the electronic and structural width of gate oxides, with interpretation through f...

Isolated neutral atoms trapped by electromagnetic fields are being studied intensively as a way of implementing a scalable quantum processor. In this approach to quantum logic the qubit basis states are represented by different ground-state hyperfine levels. The hyperfine states have decoherence times that are potentially many seconds long, limited mainly by weak interactions with the trapping ...

Tuberculosis (TB) is endemic in Eurasian wild boar (Sus scrofa) and red deer (Cervus elaphus) in south central Spain, where evidence suggests transmission to domestic cattle. Known risk factors for TB at the interface between livestock and wild ungulate species include density and spatial overlap, particularly around waterholes during summer. We evaluated the effectiveness of selective exclusio...

LI, WENMEI. Characterization of High-κ Gate Stacks in Metal-Oxide-Semiconductor Capacitors. (Under the direction of Dr. Dennis M. Maher) The purpose of this research has been to use off-line characterization techniques to establish material-specific properties of gate-stack constituents (i.e., high-κ dielectric stacks and electrodes) and complete gate-stack structures. Hence, the characterizati...

In this paper a new phase-frequency detector is proposed using transmission gates which can detect phase difference less than 500ps. In other word, the proposed Phase-frequency Detector (PFD) can work in frequencies higher than 1.7 GHz, whereas a conventional PFD operates at frequencies less than 1.1 GHz. This new architecture is designed in TSMC 0.13um CMOS Technology. Also, the proposed PFD a...
