a simple emergency risk prediction tool should be developed for clinicians to quickly identify the prognosis of patients with acute aortic dissection.we enrolled 280 patients with acute aortic dissection admitted to emergency department between may 2010 and february 2013. multivariate logistic regression analysis was performed to identify independent predictors of in-hospital death.the in-hospi...

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...

the vast use of linear prediction coefficients (lpc) in speech processing systems has intensified the importance of their accurate computation. this paper is concerned with computing lpc coefficients using evolutionary algorithms: genetic algorithm (ga), particle swarm optimization (pso), dif-ferential evolution (de) and particle swarm optimization with differentially perturbed velocity (pso-dv...

â  using of prediction models is one of the methods of financial performance prediction. financial ratios are employed as predictive variable in prediction models. the main purpose of this study is to compare the incremental information content of accrual and cash ratios for prediction and evaluation of the financial performance of business entities by data mining models. in align with research...

We show that the protein folding problem in the two-dimensional H-P model is NP-complete.

The lattice approach to biological structural analysis was made popular by the HP model for protein folding, but had not been used previously for RNA secondary structure prediction. We introduce the Delta toolset for the structural analysis of biological sequences on a 3D triangular lattice. The Delta toolset includes a proof-of-concept RNA folding program that is both fast and accurate in pred...

The problem: The standard Hamblin/Karttunen semantics for Polar Questions (PolQ), (1a), and alternative questions composed of two polar alternatives (AltQ∨N), (1b), induces equivalent partitions: (1a-i) and (1b-i) (the canonical intonation is as indicated ([7, 5])). (1) a. Are you making pasta L * H-H% ? (final raising) [PolQ] i. (1a)(w 0)= λq[q = λw.make(pasta, you, w) ∨q = λw.¬make(pasta, you...
