S U M M A R Y Coda wave interferometry (CWI) utilizes multiply scattered waves to diagnose small changes in a medium by using the scattering medium as an interferometer. Since the medium is usually stationary over the duration of a seismic experiment, different (non-overlapping) time windows in the coda allow for independent estimates of the medium perturbation. If the seismograms are contamina...

This paper focuses on the perception and production of the English alveolar stops (/t/ and /d/) in syllable coda by Brazilian learners of English. In the production test, the participants read a list of English sentences containing alveolar stops in word-final position. The preceding and following phonological contexts were controlled, so that the effect of context on the production of the alve...

Ultrasonic measurements are used in civil engineering for structural health monitoring of concrete infrastructures. The late portion the ultrasonic wavefield, coda, is sensitive to small changes elastic moduli material. Coda Wave Interferometry (CWI) correlates these coda with wavefield recorded intact, or unperturbed, specimen reveal amount velocity change that occurred. CWI has potential dete...

UNLABELLED BACKGROUND Malaria causes immense human morbidity and mortality globally. The plasmodium species vivax and falciparum cause over 75 % clinical malaria cases. Until now, gene-based strategies against malaria have only been applied to plasmodium species and their mosquito-vector. Merozoites of these two respective plasmodium species target and invade red blood cells (RBCs) by using ...

This paper reports a numerical study of the sensitivity and applicability Nonlinear Coda Wave Interferometry (NCWI) method in heterogeneous material with localized microcracked zone. We model influence strong pump wave on zone as small average increase length each crack. Further probing this multiply scattered ultrasonic induces changes to coda-type signal, which are quantified coda interferome...

A cotransformation system using somatic embryos was developed to produce grapevines free of selectable marker genes. This was achieved by transforming Vitis vinifera L. "Thompson Seedless" somatic embryos with a mixture of two Agrobacterium strains. The first strain contained a binary plasmid with an egfp gene of interest between the T-DNA borders. The second strain harbored the neomycin phosph...

We close by describing two rather unusual applications of complex variables. The details are beyond the scope of this book, but the ideas involved definitely deserve mention. The first area of application is fluid dynamics. It was observed already in the nineteenth century that the equations describing the incompressibility and irrotationality of fluids are just the Cauchy-Riemann equations for...
