Matter-wave solitons with a periodic, piecewise-constant scattering length
Scattering collision uneven condensate spatial modulation nonlinear schrodinger equation
2014/12/25
Motivated by recent proposals of “collisionally inhomogeneous” Bose-Einstein condensates (BECs), which have a spatially modulated scattering length, we study the existence and stability properties of ...
On the incidence-prevalence relation and length-biased sampling
prevalent cohort right censoring left truncation incidence rate nonparametric maximum likelihood estimator
2010/4/30
For many diseases, logistic and other constraints often render large incidence
studies difficult, if not impossible, to carry out. This becomes a drawback,
particularly when a new incidence study is...
