Phantom cosmology as a simple model with dynamical complexity
, 2004 We study the Friedmann-Robertson-Walker model with phantom fields modelled in terms of scalar fields. We apply the Ziglin theory of integrability and find that the flat model is nonintegrable.

Analytic Light-Curves of Gamma-Ray Burst Afterglows: Homogeneous versus Wind External Media [PDF]
, 2000 Assuming an adiabatic evolution of a Gamma-Ray Burst (GRB) remnant interacting with an external medium, we calculate the injection, cooling, and absorption break frequencies, and the afterglow flux for plausible orderings of the break and observing ...

Assessment of the pre-analytical phase of a clinical analyses laboratory
Jornal Brasileiro de Patologia e Medicina Laboratorial, 2018 ABSTRACT Introduction: The pre-analytical phase encompasses the procedures prior to the performance of the laboratory tests, which are the physician's requisition, patient and tests registration, collection and transport of samples. This phase involves different professionals and is responsible for the majority of the laboratory errors.

Serum and Urine Copper – Contamination and Stability
Acta Medica Bulgarica, 2015 Pre-analytical factors of variation need to be carefully considered and investigated in efforts to harmonize all aspects of the total testing process. This study aimed to evaluate contamination and stability in copper (Cu) analysis of serum and urine by ...

The Effect of Pre-Analytical Conditions on Blood Metabolomics in Epidemiological Studies
Metabolites, 2019 Serum and plasma are commonly used in metabolomic-epidemiology studies. Their metabolome is susceptible to differences in pre-analytical conditions and the impact of this is unclear.

Sub-TeV proton beam generation by ultra-intense laser irradiation of foil-and-gas target [PDF]
, 2012 A two-phase proton acceleration scheme using an ultra-intense laser pulse irradiating a proton foil with a tenuous heavier-ion plasma behind it is presented. The foil electrons are compressed and pushed out as a thin dense layer by the radiation pressure
