In fact, over- or sustained expression of a given clock gene induces segmentation defects and consequent severe skeletal malformations such as disorganized and fused vertebrae and ribs.
In a given cycle of the clock, NICD activates transcription, resulting in the production of cytoplasmic protein after some delay, T1.
This was not surprising because a systematic analysis of circadian-controlled genes revealed that even though in a given organ 1000 3000 genes are transcriptionally clock-controlled, in tissue culture of most commonly used mammalian cell lines, transcription of only 10 20 genes, mainly those of the core clock genes, was controlled by the TTFL of the circadian clock.
To support this conjecture, this paper demonstrates, through detailed circuit design and timing analysis that different proposed NoC architectures to date are guaranteed to achieve the minimum possible clock cycle times in a given CMOS technology, usually specified in normalized units as 10 15 FO4 delays.
A slower segmentation clock would be expected to give rise to fewer, larger somites in a given length of time when compared to a similar clock with a faster pace.
The molecular clock is the rate at which mutations, and any resulting evolutionary changes, occur in a given species.
A prediction of the clock and wave-front model of somitogenesis is that a longer clock period will result, assuming a constant wave-front speed, in the formation of fewer, larger somites in a given time.
For a given X-architecture clock tree that connects n clock sinks, we consider the antenna effect in the clock tree and propose a discharge-path-based antenna effect detection method.
This does not necessarily represent the current status (at a given point in wall-clock time) of all running simulations.
Rather, we assume more realistically that each clock is synchronized with a reference clock with a given (nonnull) inaccuracy.
