Tuberculous pleural effusion (TPE) and malignant pleural effusion (MPE) are the 2 most frequent causes of exudative pleural effusions (PEs). However, the clinical differentiation is challenging.Metabolic signatures in pleural effusion from 156 patients were profiled. An integrated semi-targeted metabolomics platform was incorporated for high throughput metabolite identification and quantitation. In...
In this paper, we propose a feature selection and representation combination method to generate discriminative features for speech emotion recognition. In feature selection stage, a Multiple Kernel Learning (MKL) based strategy is used to obtain the optimal feature subset. Specifically, features selected at least n times among 10-fold cross validation are collected to build a new feature subset named...
Seismic migrations dominate about 90 percent of the computation cycles in the oil and gas industry. With the demand to handle high-density data and more complicated physics models, migration applications always call for more computing power, and they adopt new architectures quickly. Current multicore and many-core architectures have significantly improved the density of computational resources within...
The data-intensive scientific discoveries are generating huge amounts of data at an alarming rate. Most of the data are multidimensional and stored in array-based file formats. The processing of such big data becomes an urgent challenge. In this paper, we present SciHive, a scalable and easy-to-use array-based query system. SciHive enables scientists to process raw array datasets in parallel with...
The Gaussian Copula Model (GCM) plays an important role in the state-of-the-art financial analysis field for modeling the dependence of financial assets. However, the existing implementations of GCM are all computationally-demanding and time-consuming. In this paper, we propose a Dataflow Engine (DFE) design to accelerate the GCM computation. Specifically, a commonly used CPU-friendly GCM algorithm...
FlexRay is a new communication protocol supported by a large group of car manufactures and automotive electronics suppliers. It's also accepted as the de-facto standard in the future. In this paper, we analyzed several message scheduling problems of FlexRay dynamic segment at first. Then we gave out a solution to improve the situations and also a detailed timing analysis. Finally, we simulated the...
