We describe the TÜBITAK-UEKAE system that participated in the Arabic-to-English and Japanese-to-English translation tasks of the IWSLT 2007 evaluation campaign. Our system is built on the open-source phrase-based statistical machine translation software Moses. Among available corpora and linguistic resources, only the supplied training data and an Arabic(More)
—Spectral self-interference fluorescence microscopy (SSFM) has been recently developed to determine the axial position of fluorescent emitters placed on reflecting dielectric structures. In this paper, we review SSFM with emphasis on its axial localization capabilities. We show that there is a tradeoff between the numerical aperture (NA) of the microscopy(More)
We theoretically study the problem of detecting dipole radiation in a fiber-based confocal microscope of high numerical aperture. By using a single-mode fiber, in contrast to a hard-stop pinhole aperture, the detector becomes sensitive to the phase of the field amplitude. We find that the maximum in collection efficiency of the dipole radiation does not(More)
Spectral self-interference microscopy (SSM) relies on the balanced collection of light traveling two different paths from the sample to the detector, one direct and the other indirect from a reflecting substrate. The resulting spectral interference effects allow nanometer-scale axial localization of isolated emitters. To produce spectral fringes the(More)
INTRODUCTION Malignant intracerebral nerve sheath tumor (MINST) is extremely rare and the origin is still unclear. The authors present the clinical, radiological, and pathological features of a malignant intracerebral giant nerve sheath tumor. CASE REPORT A giant tumor in the right frontotemporoparietal lobes causing a midline shift was detected in a(More)
We describe the T ¨ UB ˙ ITAK submission to the IWSLT 2012 Evaluation Campaign. Our system development focused on utilizing Bayesian alignment methods such as varia-tional Bayes and Gibbs sampling in addition to the standard GIZA++ alignments. The submitted tracks are the Arabic-English and Turkish-English TED Talks translation tasks.
BACKGROUND Ultrasound is as a noninvasive method commonly used in the work-up of thyroid nodules. This study aimed to evaluate the usefulness of sonographic and elastosonographic parameters in the discrimination of malignancy. PATIENTS AND METHODS 150 thyroid nodules were evaluated by gray-scale, Doppler and elastosonography. The cytological analysis(More)
To the Editor In a recent issue of Journal of Geriatric Cardiology, we read the article by LIU, et al. with interest. [1] They aimed to investigate whether red cell distribution width (RDW) had a relationship with mortality in elderly patients after percuta-neous coronary intervention (PCI). The authors concluded that, RDW is an independent predictor of the(More)
To the editor We read the article entitled 'Cognitive impairment in heart failure patients' by Leto, et al. [1] with great interest. In this review, they demonstrated pathophysiological determinants of cognitive impairment in heart failure (HF) population. HF prevalence is increasing in the general population throughout the world. As HF is a complex(More)
