Optical encoders are commonly used in macroscopic machines to make precise measurements of distance and velocity by translating motion into a periodic signal. Here we show how Forster resonance energy transfer can be used to implement this technique at the single-molecule scale. We incorporate a series of acceptor dye molecules into self-assembling DNA, and the periodic signal resulting from un...
Résumé. — L'objet du présent article consiste en un réexamen du résultat suivant récemment obtenu par Forster : dans le cas des cristaux liquides nématiques, il n'est pas possible de déterminer de manière complète, à partir de la matrice hydrodynamique, les amplitudes liées à tous les modes diffusifs. Nous montrons qu'à partir des lois de symétrie d'inversion spatiale et d'inversion de temps, c...

Eight species of gastrointestinal helminths were obtained from the red-billed gull (Larus novaehollandiae scopulinus Forster, 1844) from Otago Peninsula, of which six were new host records. One of these, Maritrema novaezelandensis (Trematoda), was a species new to science which is being described elsewhere; the other five were Curtuteria australis (Trematoda), Echinoparyphium recurvatum (Tremat...
The maze task was created for psycholinguistic experimental testing (Forster et al., 2009). However, this paper explores the merits of this task as a language training program for beginning Spanish learners. The attributes of providing ample comprehensible input and immediate corrective feedback allow the maze task to be considered as a potential supplemental pedagogical tool. Moreover, transfe...
INTRODUCTION Farmers as a group have unique attitudes, sources of stress and a heightened risk of suicide. In the context of a prolonged drought and associated stress and increased risk of mental-health problems, this study provides an insight into the levels of psychological distress experienced by different demographic groups within the Australian farming community. The study also addresses a...
تحقیق حاضر جهت تعیین گونههای زیرخانواده Ophioninae (Hymenoptera: Ichneumonidae) در بعضی قسمتهای جنوبی ایران (استانهای فارس و هرمزگان) انجام شد. نمونهها طی سالهای 1391-1392 با استفاده از تلههای مالیز، نوری و تور حشرهگیری در زیستگاههای مختلف جمعآوری شدند. دوازده گونه متعلق به سه جنس (Enicospilus Stephens, 1835؛ Ophion Fabricius و Eremotylus Forster) شناسایی شدند که از بین آنها پنج گونه...
