Eruptions at Lone Star Geyser, Yellowstone National Park, USA: 1. Energetics and eruption dynamics

[1] Geysers provide a natural laboratory to study multiphase eruptive processes. We present results from a 4 day experiment at Lone Star Geyser in Yellowstone National Park, USA. We simultaneously measured water discharge, acoustic emissions, infrared intensity, and visible and infrared video to quantify the energetics and dynamics of eruptions, occurring approximately every 3 h. We define four...

CASES FOR DIAGNOSIS Intermittent Vesiculous Eruption in a Child

Blood tests were requested, including a complete blood count, biochemistry, antinuclear antibody, and extractable nuclear antibody, and measurement of porphyrins in blood, feces, and 24-hour urine; all the results were normal. Histopathology Biopsy of a vesicle was performed, revealing an intraepidermal blister with a few necrotic keratinocytes and an abundant dermal inflammatory infiltrate (Fi...

Automatic Verification of Intermittent Systems

Transiently powered devices have given rise to a new model of computation called intermittent computation. Intermittent programs keep checkpointing the program state to a persistent memory, and on power failures, the programs resume from the last executed checkpoint. An intermittent program is usually automatically generated by instrumenting a given continuous program. The behaviour of the cont...
