We used Cox regression to estimate hazard ratios for stillbirth, early neonatal mortality (days 0-6), and subsequent mortality (beginning on day 7) in vaccinated compared with non-vaccinated women, with fetal/infant age as the study timescale, adjusting for mother's age at birth, body mass index, parity, smoking, country of birth, disposable income, and sex of offspring.
Because of the strong association between dementia and age, for all models, we used age at diagnosis, death, or censoring as the timescale and adjusted for baseline age (32).
Timescale was adjusted for higher level taxa based on Rota-Stabelli et al. (2013), for Holometabola according to Wiegmann et al. (2009) and the remaining groups based on their fossil record (http://insects.about.com/od/evolution/a/Timeline-of-Fossil-Insects-by-Order.htm ), in order to correlate important events in plant and insect evolution with the emergence of insect olfactory receptors.
Taking into account the highly dynamic and heterogeneous nature of individual synapses, ion channels, transmitters, and their receptors, understanding how individual neurons and neuronal populations maintain stable activity over long timescales or adjust their properties to changes in their external environment is an important and difficult challenge.
All models were internally stratified by year of birth, age and gender, using time since inclusion as the timescale, and were subsequently adjusted for socio-economic status and co-morbidity at baseline.
The NetEq algorithm's timescale modification inherently adjusts for clock drift in a continuous sample-by-sample fashion and thereby avoids such step-wise concealment.
Hazard ratios per category difference in physical activity were estimated separately with data from each location, using Prentice-weighted Cox regression, with age as the underlying timescale and additionally adjusting for educational level, smoking status, alcohol consumption and energy intake.
The timescale set to find the solution is five years.
It is not possible to adjust the cryoplant compressors quickly enough to follow the pulse loads and even if they could be adjusted on a longer timescale of 100 s or so, some phases of operation would force the cryoplant to operate in regimes with very low efficiency or where there is a tendancy to instability.
Model 1 was adjusted for age (as timescale), sex, and years of education.
