By means of coupled-cluster theory, molecular properties can be computed with an accuracy often exceeding that of experiment. The high-degree polynomial scaling of the coupled-cluster method, however, remains a major obstacle

A CCO based signal processing IC that computes a fully parallel single quadrant vector-matrix multiplication has been designed and fabricated with a 2j..un CCO/CMOS process. The device incorporates an array of Charge Coupled Devices (CCO) which hold an analog matrix of charge encoding the matrix elements. Input vectors are digital with 1 8 bit accuracy.

A type of coupled map lattice (CML) is considered in this paper. What we want to do is to define the form of a traveling wave solution and to reveal its existence. Due to the infinite property of the problem, we have tried the periodic case, which can be dealt with on a finite set. The main approach for our study is the implicit existence theorem. The results indicate that if the parameters of ...

By combining our theoretical calculation and recently measured electric quadrupole hyperfine structure constant of the 3d 2 D 5/2 state in the singly ionized 43 Ca, we determine its nuclear quadrupole moment to one percent accuracy. The obtained result, −0.0444(6)b, is about ten percent improvement over the considered standard value. We have employed the relativistic coupled-cluster theory at s...

An integrating sphere charge coupled device ~CCD!-based measurement system has been developed to accurately characterize the optoelectronic performance of organic polymer light-emitting devices ~PLEDs!. By theoretically analyzing a previously developed lens-coupled method and comparing it with the integrating sphere CCD-based method, we have found that the integrating sphere-based measurement m...

2014 A method for the approximate transient analysis of the BCCD is presented. The solution is obtained by considering only the nearly-linear Poisson/Laplace’s equation in a completelydepleted/charge-neutral region and subsequent estimate of carrier flow across the interface between the charged and neutral regions. Additional factors are introduced in the solution of the equations to ensure tha...

A 'turn-on' fluorescent colorimetric device for Hg(2+) sensing was built using a dual light-emitting diode system. Fluorescence generated from a rhodamine derivative (RHD), an indicator for Hg(2+) sensing, was combined with a background red light, and the complex light was captured by a commercial charge coupled device camera or by the naked eye.
