STUDY OBJECTIVE To evaluate methods for calculating life expectancy in small areas, for example, English electoral wards. DESIGN The Monte Carlo method was used to simulate the distribution of life expectancy (and its standard error) estimates for 10 alternative life table models. The models were combinations of Chiang or Silcocks methodology, 5 or 10 year age intervals, and a final age inter...

`ronswanson` provides a simple-to-use framework for building so-called table or template models `astromodels`the modeling package multi-messenger astrophysical data-analysis framework, `3ML`. With `astromodels` and `3ML` one can build the interpolation of physical model result an expensive computer simulation. This then enables efficient reevaluation while, example, fitting it to dataset. While...

life table parameters of the beet armyworm, spodoptera exigua (hã¼bner), on four sugar beet cultivars (renger, fd0005, dorothea and shirin) were studied in laboratory at 27 â± 1â°c, 60 â± 5% rh and a photoperiod of 16l: 8d hours. the larvae successfully developed on all cultivars. the shortest and longest total developmental time were recorded on fd0005 and renger, respectively. the development...

abstract: colorado potato beetle (cpb), leptinotarsa decemlineata (say),is the most important insect pest of potato in iran. if local potato varieties vary in susceptibility to the pest, host plant resistance may provide management benefits to potato growers. a life table study was carried out to determine the relative suitability of four common potato varieties (agria, marfona, savalan and sat...

the life table parameters of macrosiphum rosae l. (hemiptera: aphididae) on five vermicompost-tea (tea-compost) concentrations (20, 40, 60, 80 and 100%) and control treatment (0%) on rosa hybrida l. were determined under laboratory conditions. there were significant differences among pre-imaginal period and adult longevity of the aphid on the five teacompost concentrations. the highest mortalit...

The objective of this study was to introduce the complementary relationship between virtual dissection table (simply, table) and free software, since authors tried to aid interested people in their studying digital human anatomy. Visible Korean (VK) team had presented the serially sectioned images and outlined images of a male cadaver. Thereafter, Anatomage (San Jose, CA) manufactured the table...

The half-cycle correction is often used in discrete Markov models to estimate state membership. This article shows that the correction, in addition to being unintuitive, actually produces the wrong results in many circumstances. These include quality-adjusted life year (QALY) weights and unit costs that differ by cycle. The half-cycle correction is also incompatible with discounting of the obta...

magnetic levitation (maglev) is amongst the most advanced technologies that are available to the transportation industries. it has already been noticed by decision makers in many countries around the globe. contrary to such high levels of interest, there are no practical algorithms available to the engineers and/or managers to assist them in analyzing economics of the maglev systems. therefore,...
