Controllability

This paper presents the design of a lower limb exoskeleton made for the purpose of wrist joint rehabilitation. The authors use the exoskeleton structure in order to cope with the user’s upper-limb kinematics and to provide motion to the wrist joint when the arm is in any possible spatial configuration.

The focus of this paper is on studying power control for Interlinking Converters (ICs) to maintain stable voltage frequency on both AC and DC sides for a hybrid AC/DC microgrid in standalone mode, as well as the balance of active and reactive power. The control method also enhancing the resilience of the hybrid AC/DC microgrid during sudden load increases or power source failures in the AC and DC subgrids.

Mathematical model of reaction systems contains experimental parameters such as reaction enthalpies, which may be inaccurate and, therefore, severely affect the computation as well as the implementation of feedback control laws. This paper aims to design an adaptive PI-like controller to regulate a chemical reaction system by means of the Lyapunov theory.

Identifying characteristics in the first 1,000 days of life that affect stunting is crucial for early prevention of stunting in children. This study aims to determine the association between pregnancy, childbirth, and child care with stunting in preschool children in the Old Quarter of Hanoi. A case-control study was conducted on 4,054 children aged 24- 72 months in Hoan Kiem district.

OECD guidelines were applied. Mice were divided into 7 groups consisting of 30 females and 10 males each. In which, the control group received the solvent, only females or males in 4 other groups were taken the testing samples (32), and both females and males of 2 remain groups were given those samples. Mice were given oral samples at a dose of 288 or 576 mg/kg/day × 7 consecutive days depending on individual group.

The study was carried out in Wistar rats for 4 consecutive weeks by oral administration at the doses of 0.77 and 2.32g/kg/day. After treatment, no significant treatment-related abnormalities were observed at both doses of Boga-TN, compared to the control group, except for the white blood cells, with lower neutrophil but higher lymphocyte values observed in the treated animals. Histopathology assessment did not show any significant variation between control and treatment groups during the study period.
