BACKGROUND: Balance impairment is one of the most distressing symptoms in Parkinson's disease (PD) even with pharmacological treatment (levodopa). A complementary treatment is high frequency stimulation in the subthalamic nucleus (STN). Whether STN stimulation improves postural control is under debate. The aim of this study was to explore the effects of STN stimulation alone on balance performance
High performance implementations of unary functions are important in many applications e.g. in the wireless communication area. This paper shows the development and VLSI implementation of unary functions like the logarithmic and exponential function, by using a novel approximation methodology based on parabolic synthesis, which is compared to the well known CORDIC algorithm. Both designs are synth
During a lightning strike to an aircraft in flight, the lightning channel becomes deformed in the airflow and displaced along the aircraft, a so-called swept stroke . The deformation and the displacement are caused by the interaction between the aerodynamic flow and the plasma properties of the channel together with the properties of the surface. The main part of the lightning current is a continu
Two eye-tracking experiments were carried out to examine the effects of eye movements in relation to the detection and non-detection of contextually congruent and incongruent antonyms such as high–low, good–bad. Experiment 1: First fixation durations on the incongruent word (p<0.01) were significantly shorter than for congruent words for detected incongruities, suggesting that language processing
