There is no balance between number of job vacancy and candidate appeared. For a single post there are lots of candidates.

We have assumed a set of transistors switching continuously at a very small time interval κ to have a small saturation current in a time frame much less than one clock period. We continued this process on every clock period with an assumption that more saturation current is drawn by a having more transistors switching during the second clock cycle. This process continues for N number of times for the system to reach the maximum saturation current. We have generated the final current ramp linear in time.

When that energy is partitioned among two dimensions instead of three, it’s thought to be sufficient to overcome van der Waals attractions and prevent the system from condensing into a 2D liquid—
even at absolute zero.
It came as a surprise, then, when in a 1985 experiment1 by Bidyut Bhattacharyya and Francis Gasparini (State University of New York at Buffalo) 3He appeared to form a quasi-2D liquid. The
researchers had added 3He to a thin film of 4He and chilled the mixture to milli - kelvin temperatures. In such a system, the 3He atoms strongly prefer to sit at the film’s surface, and because 4He becomes a superfluid, they can move about that surface almost as easily as they would in free space.
