[HTML][HTML] Finite-time stability analysis of fractional order time-delay systems: Gronwall's approach

MP Lazarević, AM Spasić - Mathematical and Computer Modelling, 2009 - Elsevier
In this paper, a stability test procedure is proposed for linear nonhomogeneous fractional
order systems with a pure time delay. Some basic results from the area of finite time and …

Revised RNA dihedral parameters for the amber force field improve RNA molecular dynamics

AH Aytenfisu, A Spasic, A Grossfield… - Journal of chemical …, 2017 - ACS Publications
The backbone dihedral parameters of the Amber RNA force field were improved by fitting
using multiple linear regression to potential energies determined by quantum chemistry …

Modeling RNA secondary structure folding ensembles using SHAPE mapping data

A Spasic, SM Assmann, PC Bevilacqua… - Nucleic acids …, 2018 - academic.oup.com
RNA secondary structure prediction is widely used for developing hypotheses about the
structures of RNA sequences, and structure can provide insight about RNA function. The …

[BOOK][B] Finely Dispersed Particles: micro-, nano-, and atto-engineering

AM Spasic, JP Hsu - 2005 - taylorfrancis.com
Over the last decade, the biggest advances in physical chemistry have come from thinking
smaller. The leading edge in research pushes closer to the atomic frontier with every passing …

DNA duplex formation with a coarse-grained model

M Maciejczyk, A Spasic, A Liwo… - Journal of chemical …, 2014 - ACS Publications
A middle-resolution coarse-grained model of DNA is proposed. The DNA chain is built of
spherical and planar rigid bodies connected by elastic virtual bonds. The bonded part of the …

The Amber ff99 force field predicts relative free energy changes for RNA helix formation

A Spasic, J Serafini, DH Mathews - Journal of chemical theory and …, 2012 - ACS Publications
The ability of the Amber ff99 force field to predict relative free energies of RNA helix formation
was investigated. The test systems were three hexaloop RNA hairpins with identical loops …

Improving RNA nearest neighbor parameters for helices by going beyond the two-state model

A Spasic, KD Berger, JL Chen, MG Seetin… - Nucleic Acids …, 2018 - academic.oup.com
RNA folding free energy change nearest neighbor parameters are widely used to predict
folding stabilities of secondary structures. They were determined by linear regression to …

Electroviscoelasticity of liquid/liquid interfaces: fractional-order model

AM Spasic, MP Lazarevic - Journal of Colloid and Interface Science, 2005 - Elsevier
A number of theories that describe the behavior of liquid–liquid interfaces have been developed
and applied to various dispersed systems, eg, Stokes, Reiner–Rivelin, Ericksen, Einstein…
