A frequency-domain algorithm for motion estimation based on overlapped transforms of the image data is developed as an alternative to block matching methods. The complex lapped transform (CLT) is first defined by extending the lapped orthogonal transform (LOT) to have complex basis functions. The CLT basis functions decay smoothly to zero at their end(More)
This article distills from available data descriptions of typical human symptoms in reaction to prompt total-body ionizing radiation in the dose range 0.5 to 30 Gy midline body tissue. The symptoms are correlated with dose and time over the acute postexposure period of 6 wk. The purpose is to provide a symptomatology basis for assessing early functional(More)
The development of effective pain treatment strategies requires the availability of precise and practical measures of treatment outcomes, the importance of which has been noted in the Veterans Health Administration's (VHA's) National Pain Initiative. This paper presents the results of a 5-year collaborative effort to develop and validate a comprehensive and(More)
Nicotine has been reported to produce both anxiolytic and/or anxiogenic effects in humans and animals. This study examined whether pretreatment with nicotine would alter anxiety in a unique runway model of approach–avoidance conflict. Food-restricted rats were trained to run a straight alley once a day to obtain food upon goal-box entry. Beginning on trial(More)
A review and analysis of the dose response relationship for the probability of acute lethality from prompt or short-term exposure to ionizing radiation is presented. The purpose of this analysis is to provide recommendations concerning estimates of casualties expected from radiation accidents, the use of nuclear weapons, or possible terrorist activities.(More)

This paper presents an estimate of the median lethal dose for humans exposed to total-body irradiation and not subsequently treated for radiation sickness. The median lethal dose was estimated from calculated doses to young adults who were inside two reinforced concrete buildings that remained standing in Nagasaki after the atomic detonation. The(More)
Rats were gavaged with 60, 48, 38, 30, or 24 ml/kg of either petroleum (P) or shale (S)-derived distillate fuel, marine (DFM). Surviving rats were killed 14 days after dosing. There was a slight difference in toxicity of the two fuels but neither fuel was very toxic. The LD50/14 was 43 ml/kg for P-DFM and 50 ml/kg for S-DFM. Lesions in rats that died(More)
