Many studies have investigated the association between methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism and hemorrhagic stroke, but the impact of MTHFR C677T on hemorrhagic stroke is unclear owing to the obvious inconsistence among those studies. This study aimed to quantify the strength of the association between MTHFR C677T polymorphism and(More)
The self-assembly of peptide amphiphiles (PAs) into nanofibers and their bioactivity as well as physical properties have been investigated by our laboratory over the past few years. We report here on the use of transmission infrared spectroscopy (IR) and polarization modulation-infrared reflection-absorption spectroscopy (PM-IRRAS) to characterize the(More)
AIM To study the clinical value and efficacy of computerized tomography (CT)-monitored microinvasive craniopuncture for traumatic epidural hematoma. MATERIAL AND METHODS Thirty-three cases of traumatic epidural hematoma patients were selected at our hospital. YL-1-type disposable intracranial hematoma smash needle puncture and drainage of hematoma were(More)
This paper presents results on controlling the surface morphology of evaporation-driven self-assembly of peptide amphiphile (PA) nanofibers by dip-pen nanolithography. These PA nanofibers, which measure only a few nanometers in diameter, can be oriented perpendicularly to the receding edge of a solution. Dragging a meniscus of PA ink with an atomic force(More)
A novel model-based controller for six-degree-of- freedom (DOF) parallel manipulator is proposed in this paper, in order to abatement the influence of platform load variety and compel the steady state errors converge to zero. In this paper, 6-DOF parallel manipulator is described as multi-rigid-body systems, the mathematical model of the 6-DOF parallel(More)
A novel model-based controller for six degree of freedom (dof) parallel manipulator-PID controller with gravity compensation is developed, in order to improve the control precision of six-dof hydraulic driven parallel manipulator with long stroke hydraulic actuator and heavy load. In this paper, six-dof parallel manipulator is described as a thirteen(More)
This paper develops methods for designing a large class of locally dynamic isotropic modified symmetric Gough-Stewart parallel micromanipulators (MSGSPMs). First, by exploiting rotational symmetric geometry, the concept of dynamic isotropy is proposed and the dynamic isotropy matrix considering the mass geometry characteristics of the payload is constructed(More)
