This paper proposes a low-power and area-efficient shift register using pulsed latches. The area and power consumption are reduced by replacing flip-flops with pulsed latches. This method solves the timing problem between pulsed latches through the use of multiple non-overlap delayed pulsed clock signals instead of the conventional single pulsed clock signal. The shift register uses a small num...

Antimicrobial effectiveness of a nanosecond-pulsed dielectric barrier discharge (DBD) was investigated and compared with that of a microsecond-pulsed DBD. Experiments were conducted on the Escherichia coli bacteria covering a topographically non-uniform agar surface acting as one of the DBD electrodes. They reveal that the nanosecond-pulsed DBD can inactivate bacteria in recessed areas whereas ...

Column generation is an indispensable tool in computational optimization to solve a mathematical program by iteratively adding the variables of the model. Even though the method is simple in theory there are many algorithmic choices and we discuss the most common ones. Particular emphasis in put on the dual interpretation, relating column generation to Langrangian relaxation and cutting plane a...

turkmen horse is one of the oldest and purest breeds in the world, but there is no information on doppler echocardiographic parameters in this horse. in the present study, pulsed-wave (pw) doppler echocardiography was performed on 42 clinically normal 3- to 15-year-old racing turkmen horses. no cardiac disease was detected with two-dimensional (2-d) real-time, m-mode, and colour flow mapping. d...

conclusions the mode of action of prf is far from being completely elucidated. the high frequency current induces an electric field that in turn seems to influence the immunity, the inflammation and other pain conducting mechanisms. our findings suggest an effect distal from the application of the current. it reaches targets that are difficultly attainable by any other means of current applicat...

introduction: adequate control of acne is difficult, regardless of the various conventional modalities. intense pulsed light (ipl) system is one of the emerging options that are become increasingly useful. methods: to achieve the best ipl parameters we evaluated the efficacy and tolerability of ipl at 752-nm wavelength, 35 j/cm2 fluence, 55-ms pulse duration in comparison with 572-nm wavelength...

background acinetobacter calcoaceticus baumannii (acb) complex are gram-negative opportunistic bacteria with low virulence properties. their resistance to antibiotics has become a matter of concern in hospital infections. objectives the present study aimed to determine the prevalence and antimicrobial susceptibility of acb isolates collected from the nemazee hospital of shiraz. in addition, pul...

The present contribution is concerned with an exact frame-based pulsed-beams expansion of planar aperture timedependent electromagnetic fields. The propagating field is described as a discrete superposition of tilted, shifted and delayed electromagnetic pulsed-beam waveobjects over the frame spectral lattice. Explicit asymptotic expressions for the electromagnetic pulsed-beam propagators are ob...

let a and b be n × m matrices. the matrix b is said to be g-row majorized (respectively g-column majorized) by a, if every row (respectively column) of b, is g-majorized by the corresponding row (respectively column) of a. in this paper all kinds of g-majorization are studied on mn,m, and the possible structure of their linear preservers will be found. also all linear operators t : mn,m ---> mn...
