A prototype of the barrel Tracking Detector of the Compact Muon Solenoid (CMS) experiment proposed for LHC was built and tested in a beam and in a magnetic field of up to 3 T. It contained six ...microstrip gas chambers, 25 cm long, and three double-sided silicon microstrip detectors, 12.5 cm long. We report some preliminary results on the performance of the chambers.
ECONF C0303241:MOCT010A,2003 Starting in the middle of November 2002, the CMS experiment undertook an
evaluation of the European DataGrid Project (EDG) middleware using its event
simulation programs. ...A joint CMS-EDG task force performed a "stress test" by
submitting a large number of jobs to many distributed sites. The EDG testbed
was complemented with additional CMS-dedicated resources. A total of ~ 10000
jobs consisting of two different computational types were submitted from four
different locations in Europe over a period of about one month. Nine sites were
active, providing integrated resources of more than 500 CPUs and about 5 TB of
disk space (with the additional use of two Mass Storage Systems). Descriptions
of the adopted procedures, the problems encountered and the corresponding
solutions are reported. Results and evaluations of the test, both from the CMS
and the EDG perspectives, are described.

The relation between catecholamine and cortisol excretion and Type A behavior, assessed using an 11-item self-report questionnaire based on the Jenkins Activity Survey, is examined in a Swedish ...sample of young adults (N = 149). Cluster analysis indicates that the items measure four aspects of Type A behavior: irritability, hurried behavior, work achievement, and competitiveness. These clusters are not correlated with measures of recent health care utilization. In both sexes, a higher total Type A behavior score is related to decreased daytime urine concentrations of norepinephrine and day and night concentrations of cortisol. In males, increased hurried behavior is related to lower night levels of norepinephrine; higher irritability and competitiveness predict lower night levels of epinephrine and cortisol and increased urine excretion rate. In females, higher irritability and lower competitiveness scores are related to increases in daytime urine excretion and slightly lower levels of cortisol. These results indicate that only certain aspects of the Type A syndrome are related to stress processes and imply that the behaviors serve to lower stress responses in early adulthood.
