We introduce a form of Rao{Blackwellization for Markov chains which uses the transition distribution for conditioning. We show that for reversible Markov chains, this form of Rao{Blackwellization always reduces the asymptotic variance, and derive two explicit forms of the variance reduction obtained through repeated Rao{Blackwellization. The result applies to many Markov chain Monte Carlo metho...

Two new species of Drawida Michaelsen, 1900, namely Drawida polydiverticulata Narayanan & Julka, sp. n. and Drawida thomasi Narayanan & Julka, sp. n., are described from material collected from the Indian state of Kerala, which lies in the Western Ghats biodiversity hotspot. Drawida elegans Rao, 1921, Drawida kanarensis Stephenson, 1917, Drawida modesta Rao, 1921, Drawida somavarpatana Rao, 192...

In this letter, numerical algorithms for computing the marginal version of the Bayesian Cramér-Rao bound (M-BCRB) for jump Markov nonlinear systems and jump Markov linear Gaussian systems are proposed. Benchmark examples for both systems illustrate that the M-BCRB is tighter than three other recently proposed BCRBs. Index Terms Jump Markov nonlinear systems, Bayesian Cramér-Rao bound, particle ...

Both the Doob-Meyer and the Graversen-Rao decomposition theorems can be proved following an approach based on predictable compensators of discretizations and weak-L technique, which was developed by K.M. Rao. It is shown that any decomposition obtained by Rao’s method gives predictability of compensators without additional assumptions (like submartingality in the original Doob-Meyer theorem or ...

the effects of some synthetic sweeteners on the rheological and physical properties of guar gum in dilute solutions were investigated.measurements include the determination of intrinsic viscosity and the particle size, surface weighted mean [d3, 2], volume weighted mean [d4,3] and specificsurface area ofguar gum andsyntheticsweeteners mixtures. the concentration of these sweeteners were 0, 0.1,...

BACKGROUND Recurrent airway obstruction (RAO) in horses is a naturally occurring dust-induced disease mainly characterized by bronchiolitis which shows histological and pathophysiological similarities to human chronic obstructive pulmonary disease (COPD). In human COPD previous investigations indicated an association with Chlamydophila psittaci infection. The present study was designed (1) to c...
