A diagnostic approach to obtaining planetary boundary layer winds using satellite-derived thermal data

The feasibility of using satellite derived thermal data to generate realistic synoptic scale winds within the planetary boundary layer (PBL) is examined. Diagnostic modified Ekman wind equations from the Air Force Global Weather Central (AFGWC) Boundary Layer Model are used to compute winds at seven levels within the PBL transition layer (50 m to 1600 m AGL). Satellite derived winds based on 62 predawn TIROS-N soundings are compared to similarly derived wind fields based on 39 AVE-SESAME II rawinsonde (RAOB) soundings taken 2 h later. Actual wind fields are also used as a basis for comparison. Qualitative and statistical comparisons show that the Ekman winds from both sources are in very close agreement, with an average vector correlation coefficient of 0.815. Best results are obtained at 300 m AGL. Satellite winds tend to be slightly weaker than their RAOB counterparts and exhibit a greater degree of cross-isobaric flow. The modified Ekman winds show a significant improvement over geostrophic values at levels nearest the surface

System size, energy and pseudorapidity dependence of directed and elliptic flow at RHIC

PHOBOS measurements of elliptic flow are presented as a function of pseudorapidity, centrality, transverse momentum, energy and nuclear species. The elliptic flow in Cu-Cu is surprisingly large, particularly for the most central events. After scaling out the geometry through the use of an alternative form of eccentricity, called the participant eccentricity, which accounts for nucleon position fluctuations in the colliding nuclei, the relative magnitude of the elliptic flow in the Cu-Cu system is qualitatively similar to that measured in the Au-Au system.Comment: Presented at the 18th International Conference on Ultra-Relativistic Nucleus-Nucleus Collisions in Budapest, Hungary, Aug. 4-9, 200

When God Demands Blood: Unusual Minds and the Troubled Juridical Ties of Religion, Madness, and Culpability

The deific decree doctrine allows criminal defendants who believe that God commanded them to kill to plead not guilty by reason of insanity to murder. The insanity defense has remained moored to its Judeo-Christian roots, which has artificially limited its bounds. While civil law has focused on individualism within religion, criminal law has imposed state-defined limits on what religion (or socially acceptable religion) is. This article argues that the deific decree doctrine is too closely tied to artificial limits on insanity imposed by nineteenth-century developments in the mental health profession and criminal law. The doctrine unacceptably privileges certain mentally ill criminal defendants whose delusions fit within an outdated model that is not psychiatrically valid. Moreover, it has disparate gender consequences that harm women with postpartum psychosis who kill their children while supporting men who kill their female partners. The article concludes by calling for the end of the deific decree doctrine and expanding the insanity defense so it more accurately tracks psychiatric understanding of mental illness
