OBJECTIVE To evaluate the possible association of Parkinson disease (PD) and melanoma in North America. DESIGN, SETTING, AND PATIENTS Thirty-one centers enrolled patients with idiopathic PD. At visit 1, a neurologist obtained a medical history. At visit 2, a dermatologist recorded melanoma risk factors, performed a whole-body examination, and performed a(More)
In this letter, a fully software implementation of scalable elliptic curve cryptography (ECC) over GF(2<i>m</i>) on a tiny microcontroller (PicoBlaze) is presented. The implementation performs the whole ECC point multiplication in only 0.257 s for m =113 bit , 0.405 s for m = 131 bit , 0.75 s for m = 163 bit and in 1.23 s for m = 193 bit . This design,(More)
m). Scalability is explored and a novel architecture is presented in this work that scales for the set of curves recommended by the ECC standards, namely, m=113,131,163,193 with minimal area overheads whilst achieving practical performance. The proposed hardware-software co-design is parameterised for 8, 16, and 32 bit data widths. The implementation of the(More)
2012 ii To my family. .. viii 5.2 A 13 seconds acceleration time series. The upper figure shows the raw acceleration, the red axis is at −1g picking up the gravity acceleration. The lower figure show the acceleration after removing gravity by subtracting the decaying average. The x-axis is in seconds, and the y-axis
