TL;DR: In this paper, the probability distribution of electrons at the output of a photomultiplier is computed by numerical integration along a contour in the complex plane, a method that is efficient even when the number of electrons is large.
Abstract: Computation of the probability distribution of electrons at the output of a photomultiplier is carried out by numerical integration along a contour in the complex plane, a method that is efficient even when the number of electrons is large. When the overall gain of the photomultiplier is fixed and the number of dynodes is increased, the single‐stage secondary distribution being assumed the same for each, the output distribution approaches an exponential form for a broad class of single‐stage distributions.

TL;DR: Rodriguez and Tsallis as mentioned in this paper showed that the N → ∞ limiting probability distributions of a recently introduced family of d-dimensional scale-invariant probabilistic models based on Leibniz-like (d + 1)-dimensional hyperpyramids are given by Dirichlet distributions for d = 1, 2,.....
Abstract: We show that the N → ∞ limiting probability distributions of a recently introduced family of d-dimensional scale-invariant probabilistic models based on Leibniz-like (d + 1)-dimensional hyperpyramids (Rodriguez and Tsallis 2012 J. Math. Phys. 53 023302) are given by Dirichlet distributions for d = 1, 2, .... It was formerly proved by Rodriguez et al that, for the one-dimensional case (d = 1), the corresponding limiting distributions are q-Gaussians , with . The Dirichlet distributions generalize the so-called Beta distributions to higher dimensions. Consistently, we make a connection between one-dimensional q-Gaussians and Beta distributions via a linear transformation. In addition, we discuss the probabilistically admissible region of parameters q and β defining a normalizable q-Gaussian, focusing particularly on the possibility of having both bell-shaped and U-shaped q-Gaussians, the latter corresponding, in an appropriate physical interpretation, to negative temperatures.

TL;DR: An improved corner frame structure and method of manufacturing it is provided.
Abstract: An improved corner frame structure and method of manufacturing it is provided. The corner is effected by joinder of channelled members by a solid bracelet having legs extending at the desired angle. Each leg is provided with a pair of spaced apart depressions. Into these depressions, tongues are struck down to bind and urge the adjacent frame members together.
