Analysts and decision makers frequently want estimates of the cost of technologies that have yet to be developed or deployed. Small modular reactors (SMRs), which could become part of a portfolio of carbon-free energy sources, are one such technology. Existing estimates of likely SMR costs rely on problematic top-down approaches or bottom-up assessments that are proprietary. When done properly,...

The study aims to survey the mortality from asthma in different occupations among Swedish men. The design was a register based cohort study where the smoking adjusted mortality due to asthma among Swedish men 1971-80 was investigated. For each occupation a smoking adjusted standardised mortality ratio (SMR) was calculated based on a linkage between official mortality statistics 1971-80 and occu...

We calculated, in narrow age bands, suicide rates for female prisoners compared with the general population between 1978 and 2004. The standardised mortality ratio (SMR) for suicide was 20.7 (95% CI 16.7-25.7), with a higher excess in younger women (<25 years, SMR=40 (95% CI 29-57); >or=25 years, SMR=20 (95% CI 15-26)). There was a trend over time for SMRs to have increased, supporting the need...

Airline cabin attendants are exposed to several potential occupational hazards, including cosmic radiation. Little is known about the mortality pattern and cancer risk of these persons. The authors conducted a historical cohort study among cabin attendants who had been employed by two German airlines in 1953 or later. Mortality follow-up was completed through December 31, 1997. The authors comp...

OBJECTIVE To determine survivorship in Wegener's granulomatosis (WG) in a well-defined multicenter cohort. METHODS Follow-up was obtained for 77 of the 85 patients enrolled in the 1990 American College of Rheumatology vasculitis classification study. RESULTS There were 28 deaths (10 females and 18 males) among the 77 patients available for follow-up. Standardized mortality ratios (SMR) were...

This study investigated mortality and causes of death between 1988 and 1999 in 14781 persons (6702 female) with Down syndrome in California, comparing age, sex, ethnicity, and other factors. Mean age at the start of follow-up was 14 years 8 months (SD 14y 10mo). During the study period 600 persons died. The standardized mortality ratio (SMR) for the population was 5.5. Blacks were at greater ri...

In hierarchical SIP networks, paging is performed to reduce location update signaling cost for mobility management. However, the cost efficiency largely depends on each mobile node’s session-to-mobility-ratio (SMR), which is defined as a ratio of the session arrival rate to the movement rate. In this paper, we propose the adaptive mobility management scheme that can determine the policy regardi...

Precision frequency detection has enabled the suspended microchannel resonator (SMR) to weigh single living cells, single nanoparticles, and adsorbed protein layers in fluid. To date, the SMR resonance frequency has been determined optically, which requires the use of an external laser and photodiode and cannot be easily arrayed for multiplexed measurements. Here we demonstrate the first electr...

BACKGROUND A national survey in Taiwan has shown that Chinese herbal therapy increases the risk of chronic kidney disease. However, it is unknown whether herbal therapy will increase the risk of urological cancers. The purpose of this study was to determine whether Chinese herbalists are at higher risk for urological cancers. METHODS We studied all Chinese herbalists in Taiwan that were regis...

OBJECTIVE Previous studies suggested a higher risk of all-cause mortality in patients with epilepsy than in the general population. However, information on the age- and sex-specific risk of mortality, as well as on the cause-specific risk of mortality has been sparse. This study aims to determine sex-, age-, and cause-specific risk of mortality among patients with epilepsy from southern Taiwan....
