In this paper we introduce a number of new features for quality estimation in machine translation that were developed for the WMT 2012 quality estimation shared task. We find that very simple features such as indicators of certain characters are able to outperform complex features that aim to model the connection between two languages.

Background: Due to the lack of information about the role of 4G/5G polymorphism of PAI-1 Gene in susceptibility to thyroid tumors, this study was performed to evaluate the potential effects of this polymorphism on clinicopathologic features of thyroid tumors in Iranian Azeri Turkish patients. Methods:In this case-control study, 90 patients with thyroid tumors ...

      Dust storms are increasingly threatening the forest ecosystem in Western Iran. Due to its coverage of vast area of Zagros forest, the Quercus brantii is at the front line of the attack. Most tree deaths in this forest are from this species. This study aims to investigate the effect of simulated dust on wood development and leaf stomata from seedlings of Persian oak. The oak seedlings were...

Different language versions of Wikipedia contain articles referencing the same place. However, an article in one language does not necessarily mean it is available in another language as well and linked to. This paper examines geotagged articles describing places in Honduras in both the Spanish and the English language versions. It demonstrates that a method based on simple features can reliabl...

We present promising results for real-time vehicle visual detection, obtained with adaBoost using new original “keypoints presence features”. These weak-classifiers produce a boolean response based on presence or absence in the tested image of a “keypoint” (~ a SURF interest point) with a descriptor sufficiently similar (i.e. within a given distance) to a reference descriptor characterizing the...

We present a consistent string theory model which reproduces the Standard Model, consisting of aD3-brane at a simple orbifold singularity. We study some simple features of the phenomenology of the model. We find that the scale of stringy physics must be in the multi-TeV range. There are natural hierarchies in the fermion spectrum and there are several possible experimental signatures of the mod...
