This paper presents an optimized synchronous hybrid scaling scheme for the 8-bit moduli set {2 − 1,2,2 + 1}. Both Look-up-tables (LUTs) and modular adders are employed efficiently to generate the accurate scaled residues. Reverse conversion from residues to the original binary number is also computed in one residue channel without further hardware cost required. Xilinx device xc6slx4 − 3tqg144 ...

A new low-power full-adder based on CMOS inverter is presented. This full-adder is comprised of inverters. Universal gates such as NOR, NAND and MAJORITY-NOT gates are implemented with a set of inverters and non-conventional implementation of them. In the proposed design approach the time consuming XOR gates are eliminated. As full-adders are frequently employed in a tree-structured configurati...

A thermodynamic model for light-emitting diodes (LEDs) is developed by considering energy and entropy flows in the system. Thermodynamic constraints have previously been considered separately for the reversible process of electroluminescence in LEDs and for light extraction and collimation in other optical systems. By considering both processes in the LED model, an irreversible upper bound for ...

INTRODUCTION There is no therapeutic approach that provides precise and rapidly reversible inhibition of motor nerve and muscle activity for treatment of spastic hypertonia. METHODS We used optogenetics to demonstrate precise and rapidly reversible light-mediated inhibition of motor nerve and muscle activity in vivo in transgenic Thy1::eNpHR2.0 mice.

Reversibly photoswitchable 1,2-bis(2-ethyl-6-phenyl-1-benzothiophene-1,1-dioxide-3-yl)perfluorocyclopentenes (EBT) having fluorescent "closed" forms were decorated with four or eight carboxylic groups and attached to antibodies. Low aggregation, efficient photoswitching in aqueous buffers, specific staining of cellular structures, and good photophysical properties were demonstrated. Alternating...
