Determination of protein subcellular localization plays an important role in understanding protein function [1]. Knowledge of subcellular localization is also essential for genome annotation and drug discovery. Moreover, abnormal subcellular localization has been correlated with several diseases, such as cancer and Alzheimer’s disease. Experimental determination of protein subcellular localizat...

This paper reports preliminary results of data-driven modeling of segmental (phoneme) duration for Hindi. Classification and Regression Tree (CART) based datadriven duration modeling for segmental duration prediction is presented. A number of features are considered and their usefulness and relative contribution for segmental duration prediction is assessed. Objective evaluation of the duration...

This paper presents an efficient Harmonic-CELP hybrid coder at 2.4 kbps utilizing the well-known characteristics of the Harmonic and CELP coders. According to frame voicing decision, the proposed hybrid coder switches the RP-VSELP coder as a fast CELP in case of unvoiced, or an improved Harmonic coder in case of voiced. The proposed Harmonic-CELP hybrid coder has several features as follows: fa...
