Since its introduction in 1997, the M-tree became a respected metric access method (MAM), while remaining, together with its descendants, still the only databasefriendly MAM, that is, a dynamic structure persisted in paged index. Although there have been many other MAMs developed over the last decade, most of them require either static or expensive indexing. By contrast, the dynamic M-tree cons...

BACKGROUND Although a variety of methods and expensive kits are available, molecular cloning can be a time-consuming and frustrating process. RESULTS Here we report a highly simplified, reliable, and efficient PCR-based cloning technique to insert any DNA fragment into a plasmid vector or into a gene (cDNA) in a vector at any desired position. With this method, the vector and insert are PCR a...

This research aimed to analyze the usage of code mixing in Divortiare novel that was written by Ika Natasssa. The objective this is find out type used Novel. study a qualitative research. technique collecting data done using documentary technique. odd number chapters are as study. were analyzed Miles and Hubberman model. findings show there three types namely: insertion, congruent lexicalizatio...

An efficient method for the construction of Csp(2)-Csp(3) bond in a regio- and stereoselective fashion involving 1,3-terminal dienes, enol triflates/nonaflates, and sodium formate under Pd(0)-catalysis is described. The three component assembly allows trapping of a π-allyl intermediate, after the initial migratory insertion of the diene, by a hydride source that leads to structurally complex an...

A newly designed strut-supported 'frustum' fascia lata valve has been described for replacement of the mitral valve. It offers the advantages of autologous tissue leaflets, ease of construction and insertion, central flow through an unobstructed mobile annulus, no ventricular outflow obstruction, and minimal intracardiac prosthetic material. Initial clinical trials which have been carried out s...

The construction of weighted splines by knot insertion techniques such as deBoor and Oslo type algorithms leads immediately to the problem of evaluating integrals of polynomial splines with respect to the positive measure possessing piecewise constant density. It is for such purposes that we consider one possible way for simple and fast evaluation of primitives of products of a polynomial B-spl...

A version of the iterated Bäcklund-Darboux transformation, where Darboux matrix takes a form of the transfer matrix function from the system theory, is constructed for the discrete canonical system and Non-Abelian Toda lattice. Results on the transformations of the Weyl functions, insertion of the eigenvalues, and construction of the bound states are obtained. A wide class of the explicit solut...
