Growth and oscillation of solutions to linear differential equations with entire coefficients having the same order

Electronic Journal of Differential Equations, 2009
In this article, we investigate the growth and fixed points of solutions of the differential equation $$ f^{(k)}+A_{k-1}(z)f^{(k-1)}+dots +A_{1}(z)f'+A_{0}(z)f=0, $$ where $A_{0}(z),dots$, $A_{k-1}(z)$ are entire functions. Some estimates are given

New rule for choice of the regularization parameter in (iterated) tikhonov method

Mathematical Modelling and Analysis, 2009
We propose a new a posteriori rule for choosing the regularization parameter α in (iterated) Tikhonov method for solving linear ill‐posed problems in Hilbert spaces. We assume that data are noisy but noise level δ is given.

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

FEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

GROWTH OF POLYNOMIALS GENERATED BY LINEARLY INDEPENDENT SOLUTIONS OF SECOND ORDER LINEAR DIFFERENTIAL EQUATIONS IN TERMS OF ITERATED \(p- \phi\) ORDER

Ural Mathematical Journal
In this article, we have studied some properties of the growth and oscillation of polynomials generated by linearly independent solutions of the second order linear differential equation \(f^{\prime \prime }+A(z)f=0\) where \(A(z)\) is a meromorphic ...

Value Distribution and Arbitrary-Order Derivatives of Meromorphic Solutions of Complex Linear Differential Equations in the Unit Disc

Mathematics, 2019
In this paper, we investigate the value distribution of meromorphic solutions and their arbitrary-order derivatives of the complex linear differential equation f ′ ′ + A ( z ) f ′ + B ( z ) f = F ( z ) in Δ

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Cooperative Equilibria in Iterated Social Dilemmas

, 2013
The implausibility of the extreme rationality assumptions of Nash equilibrium has been attested by numerous experimental studies with human players. In particular, the fundamental social dilemmas such as the Traveler’s dilemma, the Prisoner’s dilemma ...

The role of practice and literacy in the evolution of linguistic structure [PDF]

, 2010
Recent iterated language learning studies have shown that artificial languages evolve over the generations towards regularity. This trend has been explained as a reflection of the learners’ biases.

Experiments to shed light on the best way to use Iterated Local Search for a complex combinatorial problem [PDF]

, 2007
Iterated Local Search (ILS) is a popular metaheuristic search technique for use on combinatorial optimisation problems. As with most such techniques, there are many ways in which ILS can be implemented.
