A new method for the simultaneous approximation of all the roots of a polynomial is given. The method converges for almost every initial approximation, the set of the exceptional starting points being a closed set of measure zero, at least if all the polynomial roots are real and simple. The method exhibits quadratic convergence not only to simple, but also to multiple roots.

Lysobacter antibioticus 13-6, isolated from the roots of Chinese cabbage, effectively controls the pathogens Plasmodiophora brassicae, Xanthomonas oryzae pv. oryzicola, X. oryzae pv. oryzae, Xanthomonas axonopodis pv. dieffenbachiae, and Pseudomonas syringae pv. tabaci. We report the first draft genome sequence of the L. antibioticus species in China.

PREMISE OF THE STUDY Cellulose is the most abundant biomolecule on the planet, yet the mechanism by which it is synthesized by higher plants remains largely unknown. In Arabidopsis thaliana (L.) Heynh, synthesis of cellulose in the primary cell wall requires three different cellulose synthase genes (AtCesA1, AtCesA3, and AtCesA6-related genes [AtCesA2, AtCesA5, and AtCesA6]). The multiple respo...

This paper argues for a distinction between word formation from roots and word formation from existing words. Focusing on Hebrew, it is shown that roots – and only roots – may be assigned multiple interpretations in different environments. When the basis for the derivation is a word, this word forces its semantic and phonological properties on any element derived from it. To account for this di...

Abstract  Hypercementosis is identified by an excessive, non-neoplastic deposition of radicular cementum and is mostly presented as a solitary lesion or in rare cases as a multiple type. It usually occurs in the premolar and molar region of mandible with no sex predilection. In this paper, we reported a 57-year-old female patient with multiple radiopaque lesions affecting right maxillary second...
