Lattice‐based hash‐and‐sign signatures using approximate trapdoor, revisited

open access: yesIET Information Security, 2022
For the purpose of improving the efficiency of the cryptosystems built upon lattice trapdoors, Chen, Genise and Mukherjee at ASIACRYPT 2019 modified the gadget trapdoor (G‐trapdoor) to an approximate trapdoor, which enables one to sample short preimages ...

Comparisons of Sampling Procedures and Time of Sampling for the Detection of Salmonella in Danish Infected Chicken Flocks Raised in Floor Systems

open access: yesActa Veterinaria Scandinavica, 2002
Bacteriological follow-up samples were taken from 41 chicken (Gallus gallus) flocks in floor systems, where Salmonella enterica (Salmonella) had been detected either directly in bacteriological samples or indirectly by serological samples.

Study on the Complexity Reduction of Observed Sequences Based on Different Sampling Methods: A Case of Wind Speed Data

open access: yesAtmosphere, 2022
Many studies have confirmed that the complexity of a time sequence is closely related to its predictability, but few studies have proposed methods to reduce the time sequence complexity, which is the key to improving its predictability.

Rational Construction of Stochastic Numerical Methods for Molecular Sampling [PDF]

open access: yes, 2012
In this article, we focus on the sampling of the configurational Gibbs-Boltzmann distribution, that is, the calculation of averages of functions of the position coordinates of a molecular $N$-body system modelled at constant temperature.
