Low serum ω-3 and ω-6 polyunsaturated fatty acids and other metabolites are associated with poor linear growth in young children from rural Malawi
arachidonic acid carnitine dehydroepiandrosterone docosahexaenoic acid malnutrition pregnenolone sulfate stunting
2018/11/21
Background: Stunting affects ~25% of children <5 y of age and is associated with impaired cognitive and motor development and increased morbidity and mortality. The pathogenesis of stunting is poorly ...
Comparison of methods of determining meteoroid range rates from linear frequency modulated chirped pulses
determining meteoroid modulated chirped pulses
2017/3/22
In this paper we present three methods for evaluating range rates of meteoroids
passing through the ionosphere, using linear frequency modulated (LFM) chirped pulse
data from the ALTAIR radar. The f...
Linear growth trajectories in Zimbabwean infants
children infants longitudinal malnutrition prenatal stunting
2018/12/19
Background: Undernutrition in early life underlies 45% of child deaths globally. Stunting malnutrition (suboptimal linear growth) also has long-term negative effects on childhood development. Linear g...
Maternal protein intake during pregnancy and linear growth in the offspring
linear growth pregnancy protein cohort maternal diet programming
2018/12/14
Background: Observational and experimental evidence demonstrates that protein intake in infancy programs linear growth. To our knowledge, few studies have examined prenatal maternal protein intake.
The association of serum choline with linear growth failure in young children from rural Malawi
betaine children choline linear growth malnutrition trimethylene-N-oxide stunting undernutrition
2018/12/3
Background: Choline is an essential nutrient for cell structure, cell signaling, neurotransmission, lipid transport, and bone formation. Choline can be irreversibly converted to betaine, a major sourc...
Studies of the Electronic Structure of Metallocene-based Second-order Non-linear Optical Dyes
Electronic Structure Metallocene Second-order Non linear Optical Dyes
2016/5/23
This paper describes a simple orbital picture for understanding the optical transitions and the second-order nonlinear optical response of metallocene-based chromophores of the form metallocene-(pi-br...
POINTWISE A POSTERIORI ERROR ESTIMATES FOR MONOTONE SEMI-LINEAR EQUATIONS
residual maximum norm
2015/12/11
We derive upper and lower a posteriori estimates for the maximum norm error in nite element solutions of monotone semi-linear equations.
The estimates hold for Lagrange elements of any xed order, n...

The KdV equation can be considered as a special case of the general equationutCf .u/x−g.uxx/x D 0;> 0;wheref is
non-linear andg is linear, namelyf .u/ D u2=2 andg.v/ D v. As the parameter t...

Robustness Properties of Nonlinear Systems:Absolute Stability of Linear Systems.
Consider a point mass falling vertically on an infinitely heavy
horizontal plate which oscillates periodically with period 2π in the vertical direction
and interacts with the particle by the l...
The objective of this paper is the linear reconstruction of a vector, up to a unimodular constant, when all phase information is lost, meaning only the magnitudes of frame coefficients are known. Reco...
Information Theory Based Estimator of the Number of Sources in a Sparse Linear Mixing Model
Information Theory Estimator of the Number of Sources Sparse Linear Mixing Model
2015/9/29
In this paper we present an Information Theoretic Estimator for the number of sources mutuallydisjoint in a linear mixing model. The approach follows the Minimum Description Length prescription and is...
THE NONCOMMUTATIVE WIENER LEMMA,LINEAR INDEPENDENCE,AND SPECTRAL PROPERTIES OF THE ALGEBRA OF TIME-FREQUENCY SHIFT OPERATORS
NONCOMMUTATIVE WIENER LEMMA LINEAR INDEPENDENCE SPECTRAL PROPERTIES OF THE ALGEBRA TIME-FREQUENCY SHIFT OPERATORS
2015/9/29
In this paper we analyze the Banach *-algebra of time-frequency shifts with absolutely summable coefficients. We prove a noncommutative version of the Wiener lemma. We also construct a faithful tracia...
Let G be a semisimple, simply connected, algebraic group defined over R. The set of real points G of G is not necessarily topologically simply connected, in which case G admits a non–trivial covering ...
Nonlinear Stochastic Perturbations of Dynamical Systems and Quasi-linear Parabolic PDE’s with a Small Parameter
Quasi linear parabolic equations parameters quasi linear initial boundary value
2015/9/28
In this paper we describe the asymptotic behavior, in the exponential time scale, of solutions to quasi-linear parabolic equations with a small parameter at the second order term and the long time beh...
