Topological defects in 1D elastic waves

It has been recently shown theoretically that a topological defect in a 1D periodic potential may give rise to two localized states within the energy gaps. In this work we present an experimental realization of this effect for the case of torsional waves in elastic rods. We also show numerically that three, or even more, localized states can be present if the parameters characterizing the topological defect are suitably varied.Comment: 3 pages, 4 figures, accepted in Physica

In Vitro Screening Test Using Leishmania Promastigotes Stably Expressing mCherry Protein

Transgenic Leishmania major and Leishmania donovani axenic promastigotes constitutively expressing mCherry were used for in vitro antileishmanial drug screening. This method requires minimal sample manipulation and can be easily adapted to automatic drug tests, allowing primary high-throughput screenings without the need for expensive and sophisticated instrumentsFil: Vacchina, Paola.
