By monitoring a network of synchronized atomic clocks that are spread far enough apart for a topological defect to have an effect on some clocks but not others, scientists could detect the existence ...

Figure 1: Schematic of an optical atomic clock where optical transitions in atoms or ions are used to stabilize the frequency of a narrow-band laser to the centre of the transition. Figure 3: ...

(TNS) — In 2003, engineers from Germany and Switzerland began building a bridge across the Rhine River simultaneously from both sides. Months into construction, they found that the two sides did not ...

At a logical level, synchronous designs are very simple and the clock just happens. But the clocking network is possibly the most complex in a chip, and it’s fraught with the most problems at the ...

Signal integrity is one of the many challenges faced by chip designers. Deep submicron technologies are unfriendly hosts for the nice, clean signals desired. The culprits that compromise signal ...
