Constraints on Reionization and Source Properties from the Absorption Spectra of z > 6.2 Quasars
, 2007 We make use of hydrodynamical simulations of the intergalactic medium (IGM) to create model quasar absorption spectra. We compare these model spectra with the observed Keck spectra of three z > 6.2 quasars with full GunnPeterson troughs: SDSS J1148+5251 (

Prediction of H2S production rate in sewer systems using the Z model: a case study in Dehloran city, Iran [PDF]
Journal of Advances in Environmental Health Research, 2018 Modeling of H2S buildup in sewers is performed due to the health problems associated with the high concentration of H2S, destruction of non-resistant structures in corrosion processes, and high costs of repairing corroded concrete sewer pipes.

Class of Z+-Valued Autoregressive Moving Average (ARMA) Processes
Revstat Statistical Journal, 2008 A convolution semigroup of probability generating functions and its related operator ⊙F are used to construct a class of stationary Z+-valued autoregressive moving average (ARMA) processes. Several distributional and regression properties are obtained. A number of ARMA processes with specific innovation sequences are presented.

Acute Neurological Events in Children With Hemoglobin SC Disease: A Multicenter Retrospective Study
Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Neurological manifestations in children with hemoglobin SC (HbSC) disease remain insufficiently characterized, particularly regarding acute events. The aim of this study was to describe the spectrum and frequency of acute neurological events in a multicenter cohort of children with HbSC disease.
