This paper describes a spread spectrum clock generator (SSCG) circuit for DisplayPort 1.2 standard. A Hershey-Kiss modulation profile is generated by dual sigma-delta modulators. The structure generates various modulation slopes to shape a non-linear modulation profile. The proposed SSCG for DisplayPort 1.2 generates clock signals with 5000 ppm down spreading with a Hershey-Kiss modulation prof...

We consider expanding maps of the circle with an almost neutral fixed point c. In this setting the ergodic averages of a smooth observable A satisfy the Central Limit Theorem. If A(c) = 0 we show that the expectation and the variance behave as the square root of the multiplier of c times rapidly oscillating functions of parameters.

We report results from the third in a series of nebular abundance studies of emission-line galaxies from the KPNO International Spectroscopic Survey (KISS). Galaxies with coarse metallicity estimates of 12 + log(O/H) less than 8.2 dex were selected for observation. Spectra of 14 galaxies, which cover the full optical region from [OII]λλ3727,3729 to beyond [SII]λλ6717,6731, are presented, and ab...

Budding yeast SPBs are embedded in the nuclear envelope and must be duplicated once per cell cycle. A structure called th...
