Surface ages of mid-size Saturnian satellites [PDF]

open access: yes, 2015
The observations of the surfaces of the mid sized Saturnian satellites made by Cassini Huygens mission have shown a variety of features that allows study of the processes that took place and are taking place on those worlds.

COVID-19 CT score and oxygen saturation level on pulse oximetry: Do they correlate? [PDF]

open access: yesJournal of Krishna Institute of Medical Sciences University
Background: Computed Tomography (CT) scan of Chest was widely used in India during COVID-19 pandemic irrespective of oxygen saturation level of the patients because of wide spread CT availability and prevalence of happy hypoxia in the COVID-19 patients ...

A Data Mining Based Protection and Classification of Transients for Two-Core Symmetric Phase Angle Regulators

open access: yesIEEE Access, 2021
Several conventional and non-conventional transient conditions cause differential relays associated with Phase Angle Regulators to malfunction. For Two-core Symmetric Phase Angle Regulators, this article investigates the suitability of time and time ...

Medium-induced gluon radiation in hard forward parton scattering in the saturation formalism

open access: yes, 2016
We derive the medium-induced, coherent gluon radiation spectrum associated with the hard forward scattering of an energetic parton off a nucleus, in the saturation formalism and within the Gaussian approximation for the relevant correlators of Wilson ...

Pore-scale characterization and modelling of CO2 flow in tight sandstones using X-ray micro-CT; Knorringfjellet formation of the Longyearbyen CO2 lab, Svalbard [PDF]

open access: yes, 2014
Rocks of the Knorringfjellet Formation in Central Spitsbergen form a potential storage reservoir for CO2 below Longyearbyen. They are characterised by a moderate porosity and low permeability.

Neutron matter from chiral effective field theory interactions

open access: yes, 2013
The neutron-matter equation of state constrains the properties of many physical systems over a wide density range and can be studied systematically using chiral effective field theory (EFT).

Mode fluctuations as fingerprint of chaotic and non-chaotic systems

open access: yes, 1996
The mode-fluctuation distribution $P(W)$ is studied for chaotic as well as for non-chaotic quantum billiards. This statistic is discussed in the broader framework of the $E(k,L)$ functions being the probability of finding $k$ energy levels in a randomly ...

The effectiveness of computed tomography for the experimental assessment of surfactant-polymer flooding

open access: yesOil & Gas Science and Technology, 2020
The Surfactant-Polymer (SP) process is a type of Chemical Enhanced Oil Recovery (CEOR) method. They are still a challenge for the petroleum oil industry mainly because of the difficulty in designing and forecasting the process behavior on the field scale.

Feasibility of study magnetic proximity effects in bilayer "superconductor/ferromagnet" using waveguide-enhanced Polarized Neutron Reflectometry

open access: yes, 2010
A resonant enhancement of the neutron standing waves is proposed to use in order to increase the magnetic neutron scattering from a "superconductor/ferromagnet"(S/F) bilayer.
