Prospects for Ray-tracing Light Intensity and Polarization in Models of Accreting Compact Objects Using a GPU

open access: yesThe Astrophysical Journal Supplement Series, 2023
The Event Horizon Telescope (EHT) has recently released high-resolution images of accretion flows onto two supermassive black holes. Our physical understanding of these images depends on the accuracy and precision of numerical models of plasma and ...

Sparse Inverse Covariance Estimation for Chordal Structures

open access: yes, 2017
In this paper, we consider the Graphical Lasso (GL), a popular optimization problem for learning the sparse representations of high-dimensional datasets, which is well-known to be computationally expensive for large-scale problems.

New family of simple $\mathfrak{gl}_{2n}(\mathbb{C})$-modules

open access: yes, 2015
We construct a new family of simple $\mathfrak{gl}_{2n}$-modules which depends on $n^2$ generic parameters. Each such module is isomorphic to the regular $U(\mathfrak{gl}_{n})$-module when restricted the $\mathfrak{gl}_{n}$-subalgebra naturally embedded ...

W-superalgebras as truncation of super-Yangians

open access: yes, 2002
We show that some finite W-superalgebras based on gl(M|N) are truncation of the super-Yangian Y(gl(M|N)). In the same way, we prove that finite W-superalgebras based on osp(M|2n) are truncation of the twisted super-Yangians Y(gl(M|2n))^{+}.

On Using Grey Literature and Google Scholar in Systematic Literature Reviews in Software Engineering

open access: yesIEEE Access, 2020
Context: The inclusion of grey literature (GL) is important to remove publication bias while gathering available evidence regarding a certain topic. The number of systematic literature reviews (SLRs) in Software Engineering (SE) is increasing but we do ...

Inconsistencies in the risk classification of alien species and implications for risk assessment in the European Union

open access: yesEcosphere, 2017
Invasive alien species (IAS) are species whose introduction or spread outside their native range threatens biological diversity, ecosystem functioning, economy, and/or public health.

Characterization of Triterpene Saponin Glycyrrhizin Transport by Glycyrrhiza glabra

open access: yesPlants, 2022
Glycyrrhizin (GL), a triterpene compound produced by Glycyrrhiza species, is a crucial pharmacologically active component of crude drugs. In contrast to the biosynthesis of GL in plants, little is known about GL transport and accumulation in plants.

Assessing the potential of Moldova’s agri-food products in the context of EU neighbourhood

open access: yesAgricultural Science, 2014
Due to the Deep and Comprehensive Free Trade Agreement signed recently between Moldova and European Union, it is of vital importance for local agri-food products to be competitive on the EU market in order to benefit from the potential gains of the ...

Reply to Comment by E. Babaev and M. Silaev, arXiv:1105.3756

open access: yes, 2011
The criticism of Babaev and Silaev notwithstanding, we conclude that our analysis is correct. We have found in our papers on two-band superconductors close to Tc, where the Ginzburg-Landau (GL) theory applies, that these materials are characterized by a ...
