Katz similarity index comparisons
In this paper we compare the Katz similarity index to two other node similarity metrics, the standard distance and the resistance distance, for both path and cycle graphs. We consider how Katz similarity varies as the parameter $α$ and the size of the graph vary. We also characterize when the three metrics give rise to different orderings of vertex pairs. In particular, we find that for all admissible values of $α$ the Katz similarity index, the resistance distance, and the distance give the …

Die Katze hat Schilddrüsenüberfunktion. Und seit einiger Zeit ist sie deswegen in Behandlung.
Die Tabletten in sie hinein zu mogeln, war schon ein wenig herausfordernd. Beim letzten Arztbesuch gab es aber keine Tabletten, also haben wir die Tropfen mitbekommen. Und das ist praktisch der easy mode: Sie fordert aktiv ihr Medikament ein, stellt sich sogar dafür auf die Hinterpfoten, wenn sie besonders ungeduldig ist, und genießt es laut schnurrend, ihr Medikament wegzuschlabbern.

A Gentle Introduction to Blind signatures: From RSA to Lattice-based Cryptography
Blind signatures were first introduced by David Chaum. They allow a user to have a message signed by a signer without revealing the message itself. This property is particularly useful in applications such as electronic voting and digital cash, where user anonymity is important. In a blind signature scheme, the user blinds their message before sending it to the signer, who signs the blinded message. The user then unblinds the signed message to obtain a valid signature that can be verified publi…

High dimensional convergence rates for sparse precision estimators for matrix-variate data
In several applications, the underlying structure of the data allows for the samples to be organized into a matrix variate form. In such settings, the underlying row and column covariance matrices are fundamental quantities of interest. We focus our attention on two popular estimators that have been proposed in the literature: a penalized sparse estimator called SMGM and a heuristic sample covariance estimator. We establish convergence rates for these estimators in relevant high-dimensional set…
