1. Evaluation of Left Ventricular Systolic Function in Patients with Coronary Microvascular Dysfunction by Three-Dimensional Speckle-Tracking Imaging
Abstract Introduction: The objective of this study is to evaluate the left ventricular systolic function of patients with coronary microvascular dysfunction (CMD) using the three-dimensional speckle-tracking imaging (3D-STI) technique. Methods: From June 2018 to June 2019,72 subjects from Huzhou Central Hospital were enrolled, including 42 CMD in-patients

2. Vaginal Distention Rodent Model for Fecal Incontinence: A Pilot Study on the Effect on Defecation Behavior
Abstract Objectives Vaginal balloon inflation simulates the compressive forces on the pelvic floor during the second phase of natural delivery. The foremost use of this animal model of vaginal distention (VD) is to study the mechanisms underlying urinary incontinence. As damage to the pelvic floor during natural birth is a common cause of fecal incontinence

3. Total cholesterol/high-density lipoprotein and inflammatory parameters in patients with polycystic ovary syndrome
SUMMARY OBJECTIVE: In this study, the hormone profile, lipid profile, and inflammatory parameters of patients with polycystic ovary syndrome were compared with those of non-polycystic ovary syndrome patients to determine predictive markers in young polycystic ovary syndrome patients who have not yet had children. METHODS: Patients’ age, height, weight, b

4. Association between tracking of extracurricular sports practice and weight status during childhood: a prospective cohort study
ABSTRACT BACKGROUND: Overweight and obesity have reached epidemic prevalences. Obesity control involves many factors and needs to begin early in childhood. OBJECTIVES: To ascertain the association between tracked extracurricular sports practice and weight status; and to analyze tracking of overweight and obesity among school-aged children. DESIGN AND SE

5. Disease activity is associated with LV dysfunction in rheumatoid arthritis patients without clinical cardiovascular disease
Abstract Objectives: The cross-sectional study aimed to assess left ventricular systolic function using global longitudinal strain (GLS) by speckle-tracking echocardiography (STE) and arterial stiffness using cardio-ankle vascular index (CAVI) in Thai adults with rheumatoid arthritis (RA) and no clinical evidence of cardiovascular disease (CVD). Methods: C

6. A METHODOLOGY TO OBTAIN ANALYTICAL MODELS THAT REDUCE THE COMPUTATIONAL COMPLEXITY FACED IN REAL TIME IMPLEMENTATION OF NMPC CONTROLLERS
Abstract Model Predictive Control, MPC and NMPC, and real-time optimization, RTO and D-RTO, are known to help plant operability through the mitigation of impacts caused by external disturbances. However, the usage of these tools in industry requires overcoming some challenges, for instance: accurate models of the process, particularly in regard to nonlineari

7. Effect of Leap Motion-based 3D Immersive Virtual Reality Usage on Upper Extremity Function in Ischemic Stroke Patients
RESUMO A VR imersiva é uma tecnologia que fornece design ambiental e rastreamento de objetos mais realistas do que a VR comum. O objetivo deste estudo foi investigar a eficácia da VR imersiva na função da extremidade superior em pacientes com AVC isquêmico. Sessenta e cinco pacientes com AVC isquêmico foram incluídos neste estudo randomizado, controla

8. STATE ESTIMATION AND TRAJECTORY TRACKING CONTROL FOR A NONLINEAR AND MULTIVARIABLE BIOETHANOL PRODUCTION SYSTEM
ABSTRACT In this paper a controller is proposed based on linear algebra for a fed-batch bioethanol production process. It involves finding feed rate profiles (control actions obtained as a solution of a linear equations system) in order to make the system follow predefined concentration profiles. A neural network states estimation is designed in order to kno

9. A System to improve the management of 5G and IoT Networks by determining the Mobile Position
Abstract The interference in adjacent cells and the control of the boundaries have being vastly investigated since the conception of the first cell phone networks. A very large number of small cells are required for new 5G mobile networks, and therefore it is even more important to determine the correct mobile station positioning as well as the control bound

10. Research of the Photoelectric Tracking and Pointing Platform Based on the Servo Control System
ABSTRACT: To improve the speed and accuracy of the photoelectric tracking and pointing platform stable tracking, we took the three-axis photoelectric tracking platform, of which the coupling among the rings is ignored, as the research object. Considering the effects of various disturbances, the stable tracking double closed-loop servo control system was buil

11. Extremum Seeking-based Adaptive PID Control applied to Neuromuscular Electrical Stimulation
Abstract A multivariable deterministic extremum seeking (ES) is being evaluated to construct an adaptive Proportional-Integral-Derivative (PID) control law for the functional Neuromuscular Electrical Stimulation (NMES) of stroke patients. The developed scheme is applied to control the position of the patient’s arm so that movements of flexion/extension for

12. A Hierarchical and Prioritized Framework in Coordinated Maneuver of Multiple Uavs Based on Guidance Regulator
ABSTRACT The structure of mission management and maneuver planning for multiple UAVs in close formation flight is investigated. This article provides a distributed and priority-based platform of guidance and control model to meet requirements for each coordinated maneuver. To accomplish the coordinated maneuvers of multiple UAVs, some levels of hierarchy fro
