Putative gamete-derived progenies from two Hylocereus species, the diploid H. monacanthus and the tetraploid H. megalanthus, were studied with the dual aims to confirm their gamete origin and to evaluate their potential use as genetic resources. An additional goal was to determine the origin (allotetraploid vs. autotetraploid) of H. megalanthus by exploring morphological variations in the di-ha...

While problems with cell line misidentification have been known for decades, an unknown number of published papers remains in circulation reporting on the wrong cells without warning or correction. Here we attempt to make a conservative estimate of this 'contaminated' literature. We found 32,755 articles reporting on research with misidentified cells, in turn cited by an estimated half a millio...

Tornadoes are known to evolve from a variety of different parent storm types, including supercells, squall lines, and other convective systems. Trapp et al. (2004; hereafter, TTGB04) classified reported tornadoes in the United States from 1998–2000 by parent storm type: cell, quasi-linear convective system (QLCS), or other. It was found that tornadoes from QLCSs, such as squall lines or bow ech...

The purpose of this paper is to obtain by different methods, and where possible to extend, the results given by Clebsch and Hillf for quintic surfaces having two distinct skew double lines. In a second paper, which will appear in an early issue of this Bulletin, I discuss a surface, due to Montesano, which has two consecutive skew double lines. The equation of a quintic surface that has xy and ...

Abstract The transmission line icing on-line monitoring device, which integrates many functions, such as thickness monitoring, wire tension, micro weather, and image/video can realize real-time condition of lines significantly improve the early warning ability lines. It is foundation a smart grid system. Therefore, how to effectively evaluate operational effectiveness terminal has become partic...
