Transcription factors such as Scl/Tal1, Lmo2, and Runx1 are essential for the development of hematopoietic stem cells (HSCs). However, the precise mechanisms by which these factors interact to form transcriptional networks, as well as the identity of the genes downstream of these regulatory cascades, remain largely unknown. To this end, we generated an Scl(-/-) yolk sac cell line to identify ca...

syllables keep their underlying tones, but in others the initial syllable determines the tonal pattern of a multisyllabic domain. Mandarin and Shanghai, two of the most studied dialects, best represent the contrast. Duanmu (1993) proposes that the two dialects differ in syllable structure but otherwise obey the same phonological constraints, including moraic trochee. However, a number of proble...

Field tests have been conducted of a broadband illuminator for active hyperspectral imaging (HSI) using a short-wave infrared supercontinuum laser (SWIR-SCL). We demonstrated irradiance comparable to the sun for two-way measurements at a 1.4 km distance between laser and target, and performed change detection and ranging. The experimental results suggest that the range resolution of our method ...

In this paper we propose a two-stage duration model using neural networks for predicting the duration of syllables in Indian languages. The proposed model consists of three feedforward neural networks for predicting the duration of syllable in specific intervals and a syllable classifier, which has to predict the probability that a given syllable falls into an interval. Autoassociative neural n...

Building and developing linguistic resources for languages is of prime importance with many areas of application. This paper focusses on a fully automatic approach to the aquisition of a syllable phonotactics for a particular language. In this approach the phonotactic constraints for a language are encoded in a finite-state phonotactic automaton the structure of which can be automatically deriv...

This dissertation establishes the pattern of prominence in Assamese and Assamese English. It shows for the first time that Assamese exemplifies a left – to – right trochaic system with an iterative binary rhythm. However, this rhythmic profile is disturbed by the occurrence of closed syllables deemed to be heavy. To support our intuitive judgements of prominence in Assamese with acoustic eviden...

It is well known that natural languages share certain aspects of their design. For example, across languages, syllables like blif are preferred to lbif. But whether language universals are myths or mentally active constraints-linguistic or otherwise-remains controversial. To address this question, we used fMRI to investigate brain response to four syllable types, arrayed on their linguistic wel...
