Lifetime of kaonium [PDF]

open access: yesPhysical Review D, 2004
The kaon--antikaon system is studied in both the atomic and the strongly interacting sector. We discuss the influence of the structures of the $f_0(980)$ and the $a_0(980)$ mesons on the lifetime of kaonium. The strong interactions are generated by vector meson exchange within the framework of the standard $SU(3)_V\times SU(3)_A$ invariant effective ...

Measurement of the lifetime of the B_c meson in the semileptonic decay channel [PDF]

open access: yes, 2008
Using approximately 1.3 fb-1 of data collected by the D0 detector between 2002 and 2006, we measure the lifetime of the B_c meson in the B_c -> J/psi mu nu X final state. A simultaneous unbinned likelihood fit to the J/\psi+mu invariant mass and lifetime

Component lifetime modelling [PDF]

open access: yes, 1994
There are two approaches to component lifetime modelling. The first one uses a reliability prediction method as described in the (military) handbooks with the appropriate models and parameters.

Standardized Lifetime Risk [PDF]

open access: yesAmerican Journal of Epidemiology, 1999
The authors propose the use of two new standardized measures of risk, the standardized lifetime risk and the standardized number of years of life lost. These measures maintain the advantages of standardized rates but are more readily understood without special training.

Measuring lifetime poverty [PDF]

open access: yesJournal of Economic Theory, 2011
The paper provides an axiomatic framework necessary to investigate the lifetime poverty for an individual as well as for the society, and to identify the appropriate axioms for their measurement. It further suggests that consumption rather than income is a more accurate measurement of the standard of living over time, especially in the context of ...

Estimating mean lifetime [PDF]

open access: yesProceedings of the National Academy of Sciences, 2003
The life expectancy implied by current age-specific mortality rates is calculated with life table methods that are among the oldest and most fundamental tools of demography. We demonstrate that these conventional estimates of period life expectancy are affected by an undesirable “tempo effect.” The tempo effect is positive when the mean age at death is

On Uncertain Lifetimes [PDF]

open access: yesJournal of Political Economy, 1977
This paper contrasts consumer choice under uncertain lifetimes with the behavior that would arise if each individual's lifetime were announced at birth. In a model that includes life insurance and excludes investments in human capital, the expected utility under uncertain lifetimes exceeds that under known lifetimes when the latter expectation is based

Lifetime costs and lifetime net public expenditures of smoking [PDF]

open access: yesEuropean Journal of Public Health, 2021
AbstractBackgroundCurrent estimates of lifetime costs of smoking are largely based on model analyses using etiologic fractions for a variety of diseases or Markov chain models. Direct estimation studies based on individual data for health costs by smoking status over a lifetime are non-existent.MethodsWe estimated lifetime costs in a societal ...
