Hypokinetic dysarthria is one of the core symptoms of Parkinson's disease, characterized by reduced loudness, slurred speech and distorted consonant productions. Dopaminergic medication for Parkinson's disease (PD) has been proven to be effective in treating limb and gross motor movement problems. However, the literature sees contradictory findings regarding dopaminergic effects on speech problems associated with PD. Previous perceptual and acoustic studies of PD hypokinetic dysarthria mostly involved heterogeneous population and variations of speech tasks which complicated data interpretation. Also, the lack of kinematic data limited our understanding of the details of articulation errors associated with PD, as well as the medication effects. Electromagnetic articulography (EMA) enabled the examination of PD articulatory patterns with high degree of accuracy and safety. The aim of the present study was to address these inconsistencies by providing an integrative description of basic kinematic and acoustic parameters of speech production about the dopaminergic effect on early PD speech by using EMA. The results revealed a significant improvement of articulatory function on dopaminergic effects for PD speech, evidenced by increased vowel space, the velocity and accelerated velocity initiation and coordination of articulation during bilabial or alveolar productions.

The simulation model of a risk-based three-tier inspection system is presented in the paper for the security management of screening passengers. In this study, passengers are classified to three risk classes(Trusted class, Regular class, and Risky class) based on their assessed risk level. A hybrid simulation model is developed to simulate the passengers' behavior from the moment they enter the inspection system until they leave the system. We study the performance evaluation of the proposed inspection system through an Arena simulation platform. The sensitivity analysis from a series of our numerical experiments shows the managerial effect of the model parameters on two performance measures in terms of passengers' average waiting time and the overall safety level.

Effects of Reduced Frequency on Network Configuration and Synchronization Transition

Chinese Physics Letters 2016年第5期33卷 14-17页

Synchronization of networked phase oscillators depends essentially on the correlation between the topological structure of the graph and the dynamical property of the elements. We propose the concept of ＇reduced frequency＇, a measure which can quantify natural frequencies of each pair of oscillators. Then we introduce an evolving network whose linking rules are controlled by its own dynamical property. The simulation results indicate that when the linking probability positively correlates with the reduced frequency, the network undergoes a first-order phase transition. Meanwhile, we discuss the circumstance under which an explosive synchronization can be ignited. The numerical results show that the peculiar butterfly shape correlation between frequencies and degrees of the nodes contributes to an explosive synchronization transition.

A novel path planning method based on particle swarm optimization (PSO) is proposed to achieve cooperative formation cruise for multi-Autonomous underwater vehicles (AUV). In particular, inspired by the virtual structure approach, particle in PSO is defined as a set of cooperative routes. These routes are composed by a series of navigation points including the initial points and the target points of corresponding vehicles. Given these navigation points, the optimization can be carried out in the search space described by vectors. By designing a reasonable cost function and a particle updating strategy, the method successfully coordinates the time and space of vehicles before vehicles arrived the formation-constrained positions, and simultaneously, preserves the formation constraint and avoids obstacles during the navigation, which provides a new perspective to address the cooperative path planning problem with a formation constraint. The feasibility and effectiveness of the proposed method are validated by experiments. © 2017 IEEE.

The production of χc1(3872) and ψ(2S) hadrons is studied as a function of charged particle multiplicity in pp collisions at a center-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 2 fb−1. For both states, the fraction that is produced promptly at the collision vertex is found to decrease as charged particle multiplicity increases. The ratio of χc1(3872) to ψ(2S) cross sections for promptly produced particles is also found to decrease with multiplicity, while no significant dependence on multiplicity is observed for the equivalent ratio of particles produced away from the collision vertex in b-hadron decays. This behavior is consistent with a calculation that models the χc1(3872) structure as a compact tetraquark. Comparisons with model calculations and implications for the binding energy of the χc1(3872) state are discussed.

The natural monopoly of China’s upstream industry and the vertical structure of industrial chain’s upstream and downstream competition is an important feature of China’s industrial economic structure, and the impact of the change of trade pattern on the energy industry, which located at the upstream of the China’s value chain, has become an important issue in the industrial economy. Since China has entered into the WTO in 2001, we use it for event analysis based on 1987-2007 China input-output data. The study calculates the upstreamness of production of the value chain in various industrial sectors of China’s energy industry every five years, and make correlation analysis of upstreamness of production and other economic indicators to check the characteristics of periodic inspection of China’s industrial structure with the development of industrial economy and the change of trade pattern.

RUM: Network representation learning throUgh multi-level structural information preservation

We have witnessed the discovery of many techniques for network representation learning in recent years, ranging from encoding the context in random walks to embedding the lower order connections, to finding latent space representations with auto-encoders. However, existing techniques are looking mostly into the local structures in a network, while higherlevel properties such as global community structures are often neglected. We propose a novel network representations learning model framework called RUM (network Representation learning throUgh Multi-level structural information preservation). In RUM, we incorporate three essential aspects of a node that capture a network's characteristics in multiple levels: a node's affiliated local triads, its neighborhood relationships, and its global community affiliations. Therefore the framework explicitly and comprehensively preserves the structural information of a network, extending the encoding process both to the local end of the structural information spectrum and to the global end. The framework is also flexible enough to take various community discovery algorithms as its preprocessor. Empirical results show that the representations learned by RUM have demonstrated substantial performance advantages in real-life tasks. Copyright © 2017, The Authors. All rights reserved.
