Abstract

Consistent weighted least square estimators are proposed for a wide class of nonparametric regression models with random regression function, where this real-valued random function of $k$ arguments is assumed to be continuous with probability 1. We obtain explicit upper bounds for the rate of uniform convergence in probability of the new estimators to the unobservable random regression function for both fixed or random designs. In contrast to the predecessors' results, the bounds for the convergence are insensitive to the correlation structure of the $k$-variate design points. As an application, we study the problem of estimating the mean and covariance functions of random fields with additive noise under dense data conditions. The theoretical results of the study are illustrated by simulation examples which show that the new estimators are more accurate in some cases than the Nadaraya--Watson ones. An example of processing real data on earthquakes in Japan in 2012--2021 is included., Comment: To appear in Statistics

Abstract

Biofilm formation is a widespread phenomenon in the microbial world. They may affect human and animal health and cause damage to various industries; at the same time, they can be useful in such fields as wastewater treatment or improving bioavailability of nutrients for plants. This fact actualizes the development of methods for studying biofilms. The present work is the first report on an optical sensor technique for the indication of bacterial biofilm formation with regard to biological variability, using plant growth-promoting rhizobacteria of the genus Azospirillum as a model. The correlation was found between the changes in electrophysical parameters recorded by the sensor system and the morphological features of bacteria from planktonic and/or biofilm cultures: the presence of motile organelles (flagella), polymorphism, and ultrastructure of cellular forms. It was established that the profiles of microbial cells recorded by the optical system were significantly different in planktonic and biofilm forms. When comparing the cells of different strains (the parental strain and its derivatives), or planktonic and biofilm bacteria, the variables recorded by the electro-optical sensor system were in agreement with the changes in bacterial micro- and ultrastructure recorded by other techniques. The results of analysis of the electrophysical profiles of A. baldaniorum Sp245 can be used as reference for revealing specific interactions between biofilm cells of this strain and various root surface components of a putative plant partner using an optical sensor system.

40. Orthogonal series and limit theorems for canonical U- and V-statistics of stationary connected observations

Author

Subjects
Mathematics - Probability
Abstract

The limit behavior is studied for the distributions of normalized U- and V-statistics of an arbitrary order with canonical (degenerate) kernels, based on samples of increasing sizes from a stationary sequence of observations satisfying classical mixing conditions. The corresponding limit distributions are represented as infinite multilinear forms of a centered Gaussian sequence with a known covariance matrix.

41. A note on exponential inequalities for the distribution tails of canonical von Mises' statistics of dependent observations

Abstract

Hoeffding-type exponential inequalities are obtained for the distribution tails of canonical von Mises' statistics of arbitrary order based on samples from a stationary sequence of random variables satisfying the {\varphi}-mixing condition. The present paper weakens the restrictions on the coefficient {\varphi}() which are contained in the paper "Exponential inequalities for the distributions of canonical U- and V-statistics of dependent observations" by Borisov and Volodko (2009). At the same time, we correct the corresponding proof in this paper.
