Relaxation and overlap probability function in the spherical and mean spherical model [PDF]

, 2002
The problem of the equivalence of the spherical and mean spherical models, which has been thoroughly studied and understood in equilibrium, is considered anew from the dynamical point of view during the time evolution following a quench from above to ...

Different retinopathy of prematurity severity and outcomes in triplets: A case report

SAGE Open Medical Case Reports, 2020
In this case report, we discuss the presentation of retinopathy of prematurity in triplets born at 25 + 3 weeks gestational age of whom each had a different birth weight, weight gain and treatment requirements. Triplet A weighed 800 g and his retinopathy

Volcanic ash infrared signature: porous non-spherical ash particle shapes compared to homogeneous spherical ash particles [PDF]

Atmospheric Measurement Techniques, 2014
The reverse absorption technique is often used to detect volcanic ash clouds from thermal infrared satellite measurements. From these measurements effective particle radius and mass loading may be estimated using radiative transfer modelling.

EQUIVALENCE OF THE PATH INTEGRAL FOR FERMIONS IN CARTESIAN AND SPHERICAL COORDINATES [PDF]

International Journal of Modern Physics A, 2013
The path integral calculation for the free energy of a spin-1/2 Dirac-fermion gas is performed in spherical polar coordinates for a flat space–time geometry. Its equivalence with the Cartesian-coordinate representation is explicitly established.

Comparison of Autorefraction and Photorefraction with and without Cycloplegia Using 1% Tropicamide in Preschool Children

Journal of Ophthalmology, 2019
Purpose. We aimed to investigate whether the accuracy of the Plusoptix A09 photorefractor in children with ametropia is enhanced by cycloplegia with 1% tropicamide. Methods. A total of 70 eyes (70 children) were retrospectively reviewed.
