We construct Markov chain algorithms for sampling from discrete exponential families conditional on a sufticient statistic. Examples include contingency tables, logistic regression, and spectral analysis of permutation data. The algorithms involve computations in polynomial rings using Grobner bases. 1. Introduction. This paper describes new algorithms for sampling from the conditional distribu...

In this paper we introduce a new construction for generalized Bhaskar Rao designs. Using this construction, we show that a generalized Bhaskar Rao design, GBRD(v, 3, A; A4) exists if and only if A == 0 (mod 12).

BACKGROUND It has been reported that equine recurrent airway obstruction (RAO) is a state of oxidative stress. Oxidant-antioxidant imbalance is known to increase the conversion of deoxyguanosine to 8-hydroxy-2-deoxyguanosine (8-OHdG) in DNA. 8-OHdG can easily be measured using ELISA tests in serum or urine samples. In this study, we analysed serum 8-OHdG levels in horses with recurrent airway o...

Purpose To investigate layer-by-layer changes in retinal thickness and reflectivity regarding the severity grade of acute retinal artery occlusion (RAO) using spectral-domain optical coherence tomography (SD-OCT). Methods This study is a retrospective, observational case-control series that took place in an institutional setting and included 148 eyes from 74 patients diagnosed with acute RAO ...

Several inequalities for the Khatri-Rao product of complex positive definite Hermitian matrices are established, and these results generalize some known inequalities for the Hadamard and Khatri-Rao products of matrices.
