Transients from Initial Conditions: A Perturbative Analysis [PDF]

open access: yes, 1997
The standard procedure to generate initial conditions (IC) in numerical simulations is to use the Zel'dovich approximation (ZA). Although the ZA correctly reproduces the linear growing modes of density and velocity perturbations, non-linear growth is ...

Improvement in Light Output of Ultraviolet Light-Emitting Diodes with Patterned Double-Layer ITO by Laser Direct Writing

open access: yesNanomaterials, 2019
A patterned double-layer indium-tin oxide (ITO), including the first unpatterned ITO layer serving as current spreading and the second patterned ITO layer serving as light extracting, was applied to obtain uniform current spreading and high light ...

Tile or Stare? Cadence and Sky Monitoring Observing Strategies that Maximize the Number of Discovered Transients [PDF]

open access: yes, 2003
To maximize the number of transients discovered on the sky, should sky-monitoring projects stare at one location or continually jump from location to location, tiling the sky? If tiling is preferred, what cadence maximizes the discovery rate?

Transient leukemia

open access: yesIndian Journal of Pathology and Microbiology, 2009
A new born with a mongoloid slant, brachycephaly and low-set ears presented at birth with a total leucocyte count of 57 x 10(3)/microL and the differential leucocyte count revealed 70% of these to be blasts. The morphology of the blasts was not characteristic of myeloid and lymphoid lineage.
