For nearly three hours, I'd been trying unsuccessfully to sleep. It was definitely not the most comfortable bed ever had—only a thin yellow and silver accordion-style pad separated my sleeping bag from particleboard platform bunk. I had no pillow; pillow too much of an extravagance haul up ten thousand feet. But glad opted for warmer, albeit slightly heavier, bag. Even though hard, it warm as c...

We present a novel approach to the translation of the English personal pronoun it to Czech. We conduct a linguistic analysis on how the distinct categories of it are usually mapped to their Czech counterparts. Armed with these observations, we design a discriminative translation model of it, which is then integrated into the TectoMT deep syntax MT framework. Features in the model take advantage...

Axonal microtubule (MT) arrays are the major cytoskeleton substrate for cargo transport. How MT organization, i.e., polymer length, number, and minus-end spacing, is regulated and how it impinges on axonal transport are unclear. We describe a method for analyzing neuronal MT organization using light microscopy. This method circumvents the need for electron microscopy reconstructions and is comp...

Overexpression of metallothioneins (MTs) protects some cells against heavy metals, mutagens, anticancer agents, and reactive oxygen species. We have examined the effect of the loss of MT expression on the cytotoxicity of anticancer agents and mutagens using embryonic fibroblast cells from transgenic mice with targeted disruptions of MT I and II genes (MT -/-). MT -/- cells expressed no detectab...

Translation, whose first traces date back at least to 3000 BC (Newmark, 1988), has always been considered time-consuming and labor-consuming. In view of this, experts have made numerous efforts to develop some mechanical systems which can reduce part of this time and labor. The advancement of computers in the second half of the twentieth century paved the ground for the invention of machine tra...

In recent years, many research studies have been conducted on the effects of magnetic field on plants. But certain mechanisms regarding magnetic influences have not been defined yet. In this study, effects of magnetic fields (MF) on the growth parameters and enzyme activities of Helianthus annuus L. were investigated. Sterilized seeds in sterile conditions were exposed to 0, 0.5, 1 and 1.5 mT o...
