Measurement of the $e^{+}e^{-}\toΣ^{0}\barΣ^{0}$ cross sections at center-of-mass energies from $2.3864$ to $3.0200$ GeV

М. Н. Ачасов, P. Adlarson, S. N. Ahmed, M. Albrecht et autres

The Born cross sections of $e^{+}e^{-}\to Σ^{0}\barΣ^{0}$ are measured at center-of-mass energies from $2.3864$ to $3.0200$ GeV using data samples with an integrated luminosity of $328.5$ pb$^{-1}$ collected with the BESIII detector operating at the BEPCII collider. The analysis makes use of …

Optimization of Governor Parameters to Prevent Frequency Oscillations in Power Systems

Lei Chen, Xiaomin Lu, Yong Min, Yiwei Zhang et autres

Negative damping of prime movers is a major cause of sustained frequency oscillations in power systems. Increasing the damping torque of prime movers by adjusting governor parameters is an effective measure to prevent frequency oscillations. The oscillation frequency is volatile and turbine …

Statistical Inference on Trimmed Means, Lorenz Curves, and Partial Area Under ROC Curves by Empirical Likelihood Method

Yumin Zhao

Traditionally the inference on trimmed means, Lorenz Curves, and partial AUC (pAUC) under ROC curves have been done based on the asymptotic normality of the statistics. Based on the theory of empirical likelihood, in this dissertation we developed novel methods to do …

Active Learning Algorithm for Threshold of Decision Probability on Imbalanced Text Classification Based on Protein-Protein Interaction Documents

Guixian Xu, Zhendong Niu, Xu Gao, Yujuan Cao et autres

The study of host pathogen protein-protein interactions (PPIs) is essential to understand the disease-causing mechanisms of human pathogens. A large number of scientific findings about PPIs are generated in the biomedical literatures. Building a document classification system can accelerate the process of …
