General CMB bispectrum analysis using wavelets and separable modes [PDF]
, 2013 In this paper we combine partial-wave (`modal') methods with a wavelet analysis of the CMB bispectrum. Our implementation exploits the advantages of both approaches to produce robust, reliable and efficient estimators which can constrain the amplitude of

Estimates of Approximation Error by Legendre Wavelet
Applied Mathematics, 2016 This paper first introduces Legendre wavelet bases and derives their rich properties. Then these properties are applied to estimation of approximation error upper bounded in spaces and by norms and , respectively. These estimate results are valuable to solve integral-differential equations by Legendre wavelet method.

Modified Legendre Wavelets Technique for Fractional Oscillation Equations [PDF]
Entropy, 2015 Physical Phenomena’s located around us are primarily nonlinear in nature and their solutions are of highest significance for scientists and engineers. In order to have a better representation of these physical models, fractional calculus is used. Fractional order oscillation equations are included among these nonlinear phenomena’s.

Population Genomic Structure of Sorghum Landraces Across Landscape, Environment and Culture. [PDF]
Mol EcolABSTRACT The spread of staple crops to diverse environments over time and their current genetic structure may reflect historical dispersal by humans, sustained human preference for particular traits and adaptation to local environments. Sorghum is a drought‐tolerant crop native to Africa cultivated by hundreds of millions of smallholders globally. Here

Adaptive Spectral Galerkin Methods with Dynamic Marking [PDF]
, 2015 The convergence and optimality theory of adaptive Galerkin methods is almost exclusively based on the D\"orfler marking. This entails a fixed parameter and leads to a contraction constant bounded below away from zero.

Angewandte Chemie, EarlyView.Gas‐phase complexation of chiral methyloxirane by achiral phenol results in induced chiroptical response of phenol. Two pseudo enantiomer complexes are observed, corresponding to hydrogen bonding from phenol to either of the lone electron pair of the methyloxirane oxygen, denoted as Pro R and Pro S, with opposite chiral deformation of phenol and ...
