We present an algorithm, based on the explicit formula for L-functions and conditional on GRH, for proving that a given integer is squarefree with little or no knowledge of its factorization. We analyze the algorithm both theoretically and practically, and use it to prove that several RSA challenge numbers are not squarefull.

the success rate of embryo production critically depends on several factors. one of the pivotal factors is a technique used for the whole procedure of in vitro fertilization (ivf) and in vitro embryo culture (ivc) (1, 2). besides the technique selected for ivf / in vitro embryo production (ivep), there is an important consideration called ivf/ivep culture dishes disinfection (3). for many years...

The Solubility Challenge is based upon intrinsic solubility data measured in one laboratory for a set of biologically relevant compounds. More than 100 entries to the Solubility Challenge have been received. In several cases multiple entries came from the same person or group. In addition, more than 5% of the prediction sheet entries were incomplete in that predictions were not reported for all...

This project evaluates the accuracy of YouTube’s automatically-generated captions across two genders and five dialects of English. Speakers’ dialect and gender was controlled for by using videos uploaded as part of the “accent tag challenge”, where speakers explicitly identify their language background. The results show robust differences in accuracy across both gender and dialect, with lower a...

This paper describes the chronicle recognition problem and reports its status in the WITAS UAV project. We describe how we use the IxTeT chronicle recognition system to define chronicles (scenarios or situations), like a vehicle passing another vehicle, and how it is incorporated in the WITAS architecture. We also discuss known problems with the current system and possible directions of future ...
