YAO Hua, SUN Yuping, LI Qing, YAO Wenhai, WANG Qiuyun, HU Jing, ABUDUREHEMAN Gulibaha, TUO Ling, JIANG Yan

《医学前沿（英文）》 2008年 第2卷 第1期   页码 108-112 doi: 10.1007/s11684-008-0020-3

摘要： This study investigates the relationship between hyperuricemia and metabolic syndrome (MS) among males of Han ethnicity in the Xinjiang Uygur Autonomous Region, China. The blood samples were collected from January to May, 2006 in Urumqi. It included 1496 subjects with ages between 20 to 70 years. All these subjects had physical examinations, blood pressure (BP) measurement and analysis for serum uric acid (SUA), fasting blood sugar (FBS), serum triglyceride (TG), serum total cholesterol (TC), serum high density lipoprotein (HDL-C) and serum low density lipoprotein (LDL-C) as well as biochemistry assay. The Data were analyzed using the Pearson Chi-Square Test, Independent-Samples -Test and the Mantel-Haenszel Test for linear trend, respectively. The results show that the prevalence of MS in the present study was 18%. Blood pressure, fasting blood sugar, body mass index (BMI), waist/hip ratio(WHR), TG, TC and LDL-C were significantly higher in the hyperuricemic group than in normal group and these parameters were strongly related to serum uric acid levels. The components of metabolic syndrome such as obesity, hyperglycemia, hypertension and dyslipidemia had a close correlation with SUA. The Odds ratios of these metabolic diseases in the hyperuricemic group were 3.097 times, 2.633 times, 2.226 times and 3.058 times of the normal SUA group, respectively. They all have a positive correlation with hyperuricemia. Hyperuricemia is closely linked to the various components of the metabolic syndrome. More emphasis should be put on the evolving control and prevalence of hyperuricemia and metabolic syndrome among males of Han ethnicity in Xinjiang.

Toward autonomous mining: design and development of an unmanned electric shovel via point cloud-based

《机械工程前沿（英文）》 2022年 第17卷 第3期 doi: 10.1007/s11465-022-0686-2

摘要： With the proposal of intelligent mines, unmanned mining has become a research hotspot in recent years. In the field of autonomous excavation, environmental perception and excavation trajectory planning are two key issues because they have considerable influences on operation performance. In this study, an unmanned electric shovel (UES) is developed, and key robotization processes consisting of environment modeling and optimal excavation trajectory planning are presented. Initially, the point cloud of the material surface is collected and reconstructed by polynomial response surface (PRS) method. Then, by establishing the dynamical model of the UES, a point to point (PTP) excavation trajectory planning method is developed to improve both the mining efficiency and fill factor and to reduce the energy consumption. Based on optimal trajectory command, the UES performs autonomous excavation. The experimental results show that the proposed surface reconstruction method can accurately represent the material surface. On the basis of reconstructed surface, the PTP trajectory planning method rapidly obtains a reasonable mining trajectory with high fill factor and mining efficiency. Compared with the common excavation trajectory planning approaches, the proposed method tends to be more capable in terms of mining time and energy consumption, ensuring high-performance excavation of the UES in practical mining environment.

Extended model predictive control scheme for smooth path following of autonomous vehicles

《机械工程前沿（英文）》 2022年 第17卷 第1期   页码 4-4 doi: 10.1007/s11465-021-0660-4

摘要： This paper presents an extended model predictive control (MPC) scheme for implementing optimal path following of autonomous vehicles, which has multiple constraints and an integrated model of vehicle and road dynamics. Road curvature and inclination factors are used in the construction of the vehicle dynamic model to describe its lateral and roll dynamics accurately. Sideslip, rollover, and vehicle envelopes are used as multiple constraints in the MPC controller formulation. Then, an extended MPC method solved by differential evolution optimization algorithm is proposed to realize optimal smooth path following based on driving path features. Finally, simulation and real experiments are carried out to evaluate the feasibility and the effectiveness of the extended MPC scheme. Results indicate that the proposed method can obtain the smooth transition to follow the optimal drivable path and satisfy the lateral dynamic stability and environmental constraints, which can improve the path following quality for better ride comfort and road availability of autonomous vehicles.

Jinlong ZHOU, Xinguang DONG, Yiping WANG, Guomin LI, Xiaojing GUO,

《环境科学与工程前沿（英文）》 2010年 第4卷 第2期   页码 183-186 doi: 10.1007/s11783-010-0021-8

摘要： Groundwater is the main source of drinking water for the urban and rural residents in the plain area of the Xinjiang Uygur Autonomous Region, China. The quality of groundwater has a direct relationship with human health. Thus, 386 groundwater samples collected from April to August in 2003 were analyzed. The samples were collected in basic evaluation units which are determined on the basis of watersheds. Total dissolved solids, total hardness, pH value, NH–N, CHOH, Chemiluminescence detection of permanganate index (COD) and intestinal germ group were evaluated according to the guidelines of Groundwater Quality Standard (GB/T14848-93). The quality of the groundwater in each evaluation unit was classified by using the One Veto Method (a unified approach stipulated by the Ministry of Water Resources). The results indicate that the groundwater in the mainstream area of the Tarim Basin and the Yerqiang River Sub-basin belongs to Category V; the groundwater in the Wulungu River Sub-basin, the Kaidu-Kongque River Sub-basin, the Kashgar River Sub-basin, the Cherchen River Sub-basin and the Hotan River Sub-basin belongs to Category IV; the groundwater in the Aibi Lake System belongs to Category II, and the groundwater of other evaluation units belongs to Category III. The causes of water quality formation were concisely analyzed. The results can be useful for the evaluation and management of water resources in the Xinjiang Plain Area.

General Optimal Trajectory Planning: Enabling Autonomous Vehicles with the Principle of Least Action

Heye Huang,Yicong Liu,Jinxin Liu,Qisong Yang,Jianqiang Wang,David Abbink,Arkady Zgonnikov,

《工程（英文）》 doi: 10.1016/j.eng.2023.10.001

摘要： This study presents a general optimal trajectory planning (GOTP) framework for autonomous vehicles (AVs) that can effectively avoid obstacles and guide AVs to complete driving tasks safely and efficiently. Firstly, we employ the fifth-order Bezier curve to generate and smooth the reference path along the road centerline. Cartesian coordinates are then transformed to achieve the curvature continuity of the generated curve. Considering the road constraints and vehicle dynamics, limited polynomial candidate trajectories are generated and smoothed in a curvilinear coordinate system. Furthermore, in selecting the optimal trajectory, we develop a unified and auto-tune objective function based on the principle of least action by employing AVs to simulate drivers’ behavior and summarizing their manipulation characteristics of “seeking benefits and avoiding losses.” Finally, by integrating the idea of receding-horizon optimization, the proposed framework is achieved by considering dynamic multi-performance objectives and selecting trajectories that satisfy feasibility, optimality, and adaptability. Extensive simulations and experiments are performed, and the results demonstrate the framework’s feasibility and effectiveness, which avoids both dynamic and static obstacles and applies to various scenarios with multi-source interactive traffic participants. Moreover, we prove that the proposed method can guarantee real-time planning and safety requirements compared to drivers’ manipulation.

Toward Trustworthy Decision-Making for Autonomous Vehicles: A Robust Reinforcement Learning Approach

Xiangkun He,Wenhui Huang,Chen Lv,

《工程（英文）》 doi: 10.1016/j.eng.2023.10.005

摘要： While autonomous vehicles are vital components of intelligent transportation systems, ensuring the trustworthiness of decision-making remains a substantial challenge in realizing autonomous driving. Therefore, we present a novel robust reinforcement learning approach with safety guarantees to attain trustworthy decision-making for autonomous vehicles. The proposed technique ensures decision trustworthiness in terms of policy robustness and collision safety. Specifically, an adversary model is learned online to simulate the worst-case uncertainty by approximating the optimal adversarial perturbations on the observed states and environmental dynamics. In addition, an adversarial robust actor-critic algorithm is developed to enable the agent to learn robust policies against perturbations in observations and dynamics. Moreover, we devise a safety mask to guarantee the collision safety of the autonomous driving agent during both the training and testing processes using an interpretable knowledge model known as the Responsibility-Sensitive Safety model. Finally, the proposed approach is evaluated through both simulations and experiments. These results indicate that the autonomous driving agent can make trustworthy decisions and drastically reduce the number of collisions through robust safety policies.

《医学前沿（英文）》 2007年 第1卷 第2期   页码 230-233 doi: 10.1007/s11684-007-0045-z

摘要： The relationship between the tenth exon C825T of G-protein β3 subunit (GNB) genetic polymorphism and hypertension in the Uygur population of China was investigated. A nested case-control study ( = 738) was carried out. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique was used to genotype GNB C825T polymorphism in 354 hypertensive (HT) and 384 normotensive (NT) Uygur subjects. The distributions of GNB C825T genotypes were CC (27.2%), TT (42.9%), and CT (29.9%) in the hypertensive subjects and CC (27.7%), TT (42.4%), CT (29.9%) in the normotensive subjects. There were no significant differences in the genotype distributions between the two groups ( = 0.0262 P = 0.99). The T allele was 51.4% in hypertensive subjects and 51.2% in normotensive subjects, which, between the two groups, was not a significant difference ( = 0.0016 P = 0.97). Further analysis shows that there is no association between C825T genotypes and age, body mass index (BMI), Glucose (GLU), Triglyceride (TG), Cholesterol (CHO), systolic blood pressure (SBP) and diastolic blood pressure (DBP). No evidence was found to suggest an association between GNB C825T polymorphism and hypertension in the Uygur population of China.

摘要：

自动驾驶汽车的快速发展给现有交通出行方式带来了全新面貌和潜在挑战。目前，L3 级及以下驾驶辅助系统已经量产，L4 级在特定场景下的一些应用也逐步开发，通过逐渐提高车辆的自动化、智能化程度来不断向完全自动驾驶发展。然而，针对L5 级自动驾驶汽车的发展思路始终未明确，而现有针对L0~L4级自动驾驶发展过程的研发方式主要基于任务驱动来进行特定场景下的功能开发，难以揭示高等级自动驾驶汽车所需解决问题的本质逻辑和物理机制，进而阻碍了迈向L5 级自动驾驶的途径。本文通过探索高等级自动驾驶系统背后的物理机制，并从驾驶的本质出发，采用推理演绎方式，提出“大脑-小脑-器官”协调平衡框架，基于“乌鸦推理+鹦鹉学舌”的混合模式，探索“自主学习+先验知识”的研究范式，实现自动驾驶汽车“自学习、自适应、自超越”特性。从系统、统一、均衡的角度出发，基于最小作用量原理和统一安全场思想，旨在为高等级自动驾驶汽车，尤其是L5 级自动驾驶的研发提供一种全新的研发思路与有效途径。

《信息与电子工程前沿（英文）》 2015年 第16卷 第2期   页码 166-172 doi: 10.1631/FITEE.1400183

摘要： This research formulates a path-following control problem subjected to wheel slippage and skid and solves it using a logic-based control scheme for a wheeled mobile robot (WMR). The novelty of the proposed scheme lies in its methodology that considers both longitudinal and lateral slip components. Based on the derived slip model, the controller for longitudinal motion slip has been synthesized. Various control parameters have been studied to investigate their effects on the performance of the controller resulting in selection of their optimum values. The designed controller for lateral slip or skid is based on the proposed side friction model and skid check condition. Considering a car-like WMR, simulation results demonstrate the effectiveness of the proposed control scheme. The robot successfully followed the desired circular trajectory in the presence of wheel slippage and skid. This research finds its potential in various applications involving WMR navigation and control.
