Submitted for the DPP09 Meeting of The American Physical Society Unsteady reconnection in MHD models GIOVANNI LAPENTA, KU Leuven — Within a MHD approach we find magnetic reconnection to progress in two entirely different ways. The first is well known: the laminar Sweet-Parker process. But a second, completely different and chaotic reconnection process is possible [1]. This regime has properties...

We describe how legacy C++ programs can be rejuvenated using C++11 features such as generalized constant expressions, perfect forwarding, and lambda expressions. In general, this work develops a correspondence between different kinds of macros and the C++ declarations to which they should be transformed. We have created a set of demacrofication tools to assist a developer in the rejuvenation of...

We report a one-pot, two-step strategy to synthesize fluorescent gold nanodots (AuNDs) co-modified with 1-(10-mercaptodecyl)-5-methylpyrimidine-2,4-dione (TSH) and 11-mercaptoundecanoic acid (MUA) through a ligand exchange reaction and demonstrate their capability of selective sulfide sensing in aqueous media on the basis of fluorescence recovery.

Rice blast is a destructive disease caused by Magnaporthe oryzae, and it has a large impact on rice production worldwide. Compared with leaf blast resistance, our understanding of panicle blast resistance is limited. The japonica landrace Jiangnanwan from Taihu Lake region in China shows highly resistance to panicle and leaf blast. In this study, three generations (F2:5, F2:6, F2:7) consisting ...

A simple nickel bis(dithiolene) complex has been developed as an excellent n-type molecular semiconductor for FETs, with an electron mobility of 0.11 cm(2) V(-1) s(-1) and an on/off ratio of 2 × 10(6) despite its small π-conjugated system. Good FET stability in ambient conditions has also been observed.

A facile method for achieving optical switching of the Dirac point and conductance in reduced graphene oxide multilayer FETs that are non-covalently functionalized with a photo-responsive spiropyran derivative is presented. The photoresponsive transition from spiropyran to merocyanine induces the reversible optical switching in graphene based FETs.

Our work focuses on the encoding of two–dimensional (2-D) graphics animated cartoons with MPEG-4. This stems from a need to stop encoding cartoons as videos and to start using methods more adapted to animated 2-D vector graphics sequences. We expected this could be an efficient coding with good versatility for various types of terminals. First, we present some technical specification for such c...

Conversion of readily available vindoline to 11-mesyloxytabersonine, a versatile synthetic intermediate for indole alkaloids, has been achieved by a 9-step sequence in 39% overall yield.
