A characterization of the set of fixed points of the Quicksort transformation
, 2000 The limiting distribution \mu of the normalized number of key comparisons required by the Quicksort sorting algorithm is known to be the unique fixed point of a certain distributional transformation T -- unique, that is, subject to the constraints of ...

The Weibull-Power Cauchy distribution: model, properties and applications
, 2017 We propose a new three-parameter distribution with increasing, decreasing, reversed-J and upside-down bathtub shaped hazard rate, called the Weibull-power Cauchy distribution. We obtain explicit expressions for the mode, ordinary, negative and incomplete

Spherical matrix distributions and cauchy quotients [PDF]
Statistics & Probability Letters, 1989 Abstract It is shown that matrix quotients of submatrices of a spherical matrix are distributed as matrix Cauchy. This generalizes known results for scalar ratios of independent normal variates. The derivations are simple and make use of the theory of invariant measures on manifolds.

Observation of Optical Precursor in Time‐Energy‐Entangled W Triphotons
Advanced Science, EarlyView.This study reports the observation of optical precursors at the triphoton level through the SSWM process. By appropriately adjusting the optical depth (OD), optical precursors are effectively separated from the main wave through utilizing the slow‐light effect to manipulate the triphoton temporal correlations in the group delay regime.

NSCT Domain Additive Watermark Detection Using RAO Hypothesis Test and Cauchy Distribution
, 2016 We presented a RAO hypothesis detector by modeling Cauchy distribution for the Nonsubsampled Contourlet Transform (NSCT) subband coefficients in the field of additive spread spectrum image watermarking. Firstly, the NSCT subband coefficients were modeled

Advanced Science, EarlyView.SGCD presents a novel approach for tissue spatial domain identification by employing interpolation to estimate inter‐spot gene expression and deconvolution to resolve cell‐type composition in both sampled and interstitial regions. By integrating gene expression, cell type, and spatial coordinates within a graph contrastive learning framework, SGCD ...
