Age-period-cohort analysis of incidence and/or mortality data has received much attention in the literature. To circumvent the non-identifiability problem inherent in the age-period-cohort model, additional constraints are necessary on the parameters ...

Strain-Induced Band Gap Variation in InGaN/GaN Short Period Superlattices
The use of strained substrates may overcome indium incorporation limits without inducing plastic relaxation in InGaN quantum wells, and this is particularly important for short-period InGaN/GaN superlattices.

Spatial variation of fruit trees in Heet district for the period 2009-2019 [PDF]
The research deals with a study and analysis of the spatial variation of fruit trees in the Heet district for the period (2009_2019), and identifies the rate of change between them, by discussing the natural and human characteristics that led to ...

On the variation of bi‐periodic waves in the transverse direction [PDF]
AbstractWeakly nonlinear, bi‐periodic patterns of waves that propagate in the ‐direction with amplitude variation in the ‐direction are generated in a laboratory. The amplitude variation in the ‐direction is studied within the framework of the vector (vNLSE) and scalar (sNLSE) nonlinear Schrödinger equations using the uniform‐amplitude, Stokes‐like ...

MONITORING IONOSPHERIC VARIATION FOR A DEFINITE PERIOD TIME IN TURKEY [PDF]
Ionosphere has been studied by a number of scientists in recent years. Since GPS observations cannot provide TEC value directly, it can be estimated from combination of observations.

Period Variation of BW Vul [PDF]
Due to the large fluctuation of the time of light maxima, in each observational season only very few observations is very dangerous for period variation research. Especially when the observation is not accurate enough such as for the early radial velocity data.

Orbital Period Refinement of CoRoT Planets with TESS Observations
CoRoT was the first space mission dedicated to exoplanet detection. Operational between 2007 and 2012, this mission discovered 37 transiting planets, including CoRoT-7b, the first terrestrial exoplanet with a measured size. The precision of the published

Regional variation in the pronunciation of /s/ in the Dutch language area [PDF]
This paper reports on an explorative sociophonetic study of the phoneme /s/ in the Dutch language area. Our aim is to investigate the regional variation in the realisation of this phoneme, and to test experimentally the observation of Collins & Mees ...

Allocating Jobs with Periodic Demand Variations [PDF]
In the context of service hosting in large-scale datacenters, we consider the problem faced by a provider for allocating services to machines. Based on an analysis of a public Google trace correspond-ing to the use of a production cluster over a long period, we propose a model where long-running services experience demand variations with a periodic ...
