Lectotypifications and taxonomic changes in the holoparasitic Orobanchaceae
Nordic Journal of Botany, EarlyView.Based on further extensive studies of specimens in various herbaria, lectotypes are designated for many taxa of holoparasitic Orobanchaceae. In particular, 47 names in the genera Boschniakia (incl. Xylanche), Cistanche, Orobanche, Phelipanche and Phelypaea are lectotypified.

Importance sampling simulation for evaluating the lower-bound BER of the Bayesian DFE [PDF]
, 2002 We extend the importance sampling (IS) simulation technique of Iltis, originally derived for Bayesian equalizers, to evaluate the lower-bound bit error rate (BER) of the Bayesian decision feedback equalizer (DFE) under the assumption of correct decisions
