Human perception of 3 briefly flashed letters in a horizontal array that subtends a visual angle of 3 degrees or less is reduced by a magnetic coil (MC) pulse given, e.g., 90 msec later. Either a round or a double square MC is effective when the lower windings or central junction region, respectively, are tangential to the skull overlying calcarine cortex(More)
A minority of normal humans experience paraesthesias (usually tingling) projected to the contralateral hand in response to individual transcranial magnetic coil (MC) pulses. The cortical source of the paraesthesias was sought by comparing their incidence with that of muscle responses to focal MC stimulation with either a figure 8 MC or with edge stimulation(More)
Streaming movies over the Internet has become increasingly popular in recent years as an alternative to mailing DVDs to a customer. In this paper we investigate the environmental- and energy-related impacts of these two methods of movie content delivery. We compare the total energy consumed and the carbon footprint impact of these two delivery methods and(More)
Ten patients developed a subacute lower motor neuron syndrome as a remote effect of Hodgkin's disease or other lymphoma. The illness usually followed a benign course independent of the activity of the underlying neoplasm. Seven of the patients improved spontaneously, and 3 became neurologically normal. Two patients died of intercurrent infections related to(More)
Bone mineral density (BMD), Chronic kidney disease(CKD), Dialysis, Secondary hyperparathyroidism. Background: Metabolic bone disease is common in the case of renal failure. The aim of this study is to compare mineral changes, hormonal changes and bone mineral density in pre-dialysis and post-dialysis renal failure patients. Hypothesis: Secondary(More)
Power-aware computing has caught the interest of researchers and users of all computing systems. In embedded systems and small devices, better management of energy translates into longer lasting and smaller batteries, which in turn implies smaller and lighter devices. In cloud, distributed, and high performance computing systems, better management of power(More)
To my parents. ACKNOWLEDGMENTS I would like to thank Ramesh Sitaraman and Prashant Shenoy, my thesis advisors, without whom I would not have received a doctorate. I am fortunate to have come in contact with many great teachers both inside and outside the department, making my time at Amherst an unforgettable experience. The town of Amherst itself has been a(More)
In the racemic title compound, C21H18O4, the chromone ring is essentially planar [maximum deviation from the least-squares plane = 0.026 (3) Å], with a dihedral angle of 78.18 (12)° between the benzene rings of the chromanone and chromenone moieties. In the crystal, there are weak π-π stacking inter-actions [minimum ring centroid separation = 3.9286 (17) Å].
