Physics of Superconducting Transition Temperatures cond-mat.supr-con This paper was written in honor of my friend Ted Geballe's 100th birthday. It concerns the physics of the superconducting Tc. Tc is a dimensional quantity, and so depends on microscopic details of a material making it a strange quantity to conside...

Efficiency of a two-stage heat engine at optimal power cond-mat.stat-mech We propose a two-stage cycle for an optimized linear-irreversible heat engine that operates, in a finite time, between a hot (cold) reservoir and a finite auxiliary system acting as a sink (source) in the first (second) stage. Under the tight...

Visual cues in estimation of part-to-whole comparison cs.HC Pie charts were first published in 1801 by William Playfair and have caused some controversy since. Despite the suggestions of many experts against their use, several empirical studies have shown that pie charts are at least as good as alternatives. From B...

Zeros of repeated derivatives of random polynomials math.PR It has been shown that zeros of Kac polynomials $K_n(z)$ of degree $n$ cluster asymptotically near the unit circle as $n\to\infty$ under some assumptions. This property remains unchanged for the $l$-th derivative of the Kac polynomials $K^{(l)}_n(z)$ for a...

Two generalisations of Leighton's Theorem math.GR Leighton's graph covering theorem says that two finite graphs with a common cover have a common finite cover.
