Level Densities of Heavy Nuclei in the Shell Model Monte Carlo Approach
(EDP Sciences, 2016)Nuclear level densities are necessary input to the Hauser-Feshbach theory of compound nuclear reactions. However the microscopic calculation of level densities in the presence of correlations is a challenging many-body ... -
'Level grading' a new graded algebra structure on differential polynomials: application to the classification of scalar evolution equations
(IOP Publishing Ltd, 2013)We define a new grading which we call the 'level grading' on the algebra of polynomials generated by the derivatives u(k+i) over the ring K-(k) of C-infinity functions of x t u u(1) ... u(k) where . This grading has the ... -
Leveraging saving-based algorithms by master-slave genetic algorithms
(Pergamon-Elsevier Science Ltd, 2011)Saving-based algorithms are commonly used as inner mechanisms of efficient heuristic construction procedures. We present a general mechanism for enhancing the effectiveness of such heuristics based on a two-level genetic ... -
Ligand-binding affinity of alternative conformers of human beta(2)-adrenergic receptor in the presence of intracellular loop 3 (ICL3) and their potential use in virtual screening studies
(Wiley, 2019)This study investigates the structural distinctiveness of orthosteric ligand-binding sites of several human beta(2) adrenergic receptor (beta(2)-AR) conformations that have been obtained from a set of independent molecular ... -
Lignite resources of Turkey: Geology reserves and exploration history
(Elsevier Science, 2014)This article aims to emphasize the importance of lignite which is the mostly used domestic energy source in the Turkish energy mix by briefly overviewing its geology reserves and exploration. Lignites are distributed in ... -
Linear Combination of Pulses for Coexistence in the IEEE 802.15.4a Standard
(IEEE, 2009)The low data rate accurate location ranging Wireless Personal Area Network zWPAN standard IEEE which is based on ultra wideband zUWBg impulse radios suggests using linear combination of pulses to reduce interference to ... -
Linear expansions for frequency selective channels in OFDM
(Elsevier GMBH Urban & Fischer Verlag, 2006)Modeling the frequency selective fading channels as random processes we employ a linear expansion based on the Karhumen-Loeve (KL) series representation involving a complete set of orthogonal deterministic vectors with a ... -
Liquid-liquid equilibria of water+propionic acid+solvent ternaries at 298.2 K
(2006)(Liquid + liquid) equilibrium (LLE) data for (water + propionic acid + solvent) were measured at T= 298.2 K and atmospheric pressure. The solvents were methyl isoamyl ketone (5-methyl-2-hexanone) and diisobutyl ketone. The ... -
