Using whitening keys is a well understood mean of increasing the key-length of any given cipher. Especially as it is known ever since Grover’s seminal work that the effective key-length is reduced by a factor of two when considering quantum adversaries, it seems tempting to use this simple and elegant way of extending the key-length of a given cipher to increase the resistance against quantum a...

A 57-year-old female presented with facial oedema, cheilitis and stomatitis that started after three overnight applications of the ‘Evolution’TM home tooth-whitening kit. Her symptoms slowly resolved without treatment 3 days after she stopped using the product. The whitening kit includes an individualized plastic dental mould, which is prepared by the dentist, and a whitening gel, which contain...

This article investigates a theoretical basis for estimating autoregressive (AR) processes for linear-recurrent signals in convolutive mixtures. Whitening of such signals is sometimes a problem in multichannel blind equalization which is intended to extract the original signals even if the signals are of a convolutive mixture type. This whitening is due to inverse-filtering which deconvolves th...

Adaptive whitening is a preprocessing technique for STFTbased onset detectors, which can improve the performance of onset detectors by compensating for spectral rolloff and dynamic variability [7]. In this MIREX submission we applied adaptive whitening to a selection of STFT-based onset detection functions (ODFs) from recent literature. Our code is oriented primarily towards use in real-time sy...

Recently in speaker recognition, performance degradation due to the channel domain mismatched condition has been actively addressed. However, the mismatches arising from language is yet to be sufficiently addressed. This paper proposes an approach which employs recursive whitening transformation to mitigate the language mismatched condition. The proposed method is based on the multiple whitenin...

PURPOSE The purpose of this study was to determine if vital tooth whitening affects oral health-related quality of life (OHRQOL) in adults age 50 years and older, and if tooth whitening causes increased participation in social activities. METHODS Using a 2 group, single blind, randomized, pre-test, multiple post-test design, 62 participants were enrolled. The experimental group used a whiten...
