The number of motor units in a muscle, the abductor pollicis longus (APL), supplied by the radial nerve was estimated. In 40 APL muscles of control subjects, the mean number of motor units was found to be 421 +/- 99 (SD). Ten patients underwent conventional EMG examination to confirm the clinical suspicion of denervation in radial nerve territory. All presented a significant reduction in the nu...

New 14C dates from archaeological sites in Oaxaca, Mexico, support R. C. Kelly's observation that intervillage raiding may begin as soon as a region has segmentary societies. The oldest defensive palisade dates to 3260-3160 B.P. in conventional radiocarbon years, only a few centuries after village life was established. Over the next millennium raiding evolved into war, with residences and templ...

A 9-year-old girl without prior trauma presented with weakness and headache. Examination showed profound left hemiplegia. MRI demonstrated a right middle cerebral artery (MCA) territory infarction. Magnetic resonance angiography showed proximal right MCA irregularity. Conventional angiography revealed an intracranial dissection (figure). Intracranial dissections are frequently spontaneous (nont...

One of the key enabling features of coherent Raman scattering (CRS) techniques is the dramatically improved imaging speed over conventional vibrational imaging methods. It is this enhanced imaging acquisition rate that has guided the field of vibrational microscopy into the territory of real-time imaging of live tissues. In this feature article, we review several aspects of fast vibrational ima...

Computer science (CS) education research is an emergent area and is still giving birth to a literature. While scholarly and scientific publishing go back to Philosophical Transactions (first published by the Royal Society in England in 1665), one of our oldest dedicated journals Computer Science Education was established less than two decades ago, in 1988. Growth which has led to the emergence ...
