Some Upper Bounds for Relative Entropy and Applications [PDF]
In this paper we derive some upper bounds for the relative entropy D(p || q) of two probability distribution and apply them to mutual information and entropy mapping.

Hölder Inequalities for a Generalized Subclass of Univalent Functions Involving Borel Distributions
In this article, by making use of the Borel distributions series, we introduce a new family of normalized holomorphic functions in the open unit disk and investigate necessary and sufficient conditions for functions f to be in this new class. Furthermore,

Coefficient Bounds for Certain Subclasses of q-Starlike Functions
By making use of q-calculus, we define and investigate several new subclasses of bi-univalent mappings related to the q-Noor integral operator. The coefficient bounds | u 2 | , | u 3 | and the Fekete−Szegő problem u ...

Coefficient Bounds for Certain Classes of Meromorphic Functions
Sharp bounds for |a1−μa02| are derived for certain classes Σ∗(Õ) and Σα∗(Õ) of meromorphic functions f(z) defined on the punctured open unit disk for which −zf′(z)/f(z) and (−(1−2α)zf′(z)+ÃŽÂ ...

Coefficient Bounds for Certain Subclasses of Bi-Univalent Function
We introduce two new subclasses of the function class Σ of bi-univalent functions defined in the open unit disc. Furthermore, we find estimates on the coefficients |a2| and |a3| for functions in these new subclasses.

ON LINEAR COMBINATIONS OF UNITS WITH BOUNDED COEFFICIENTS [PDF]
Let \(O\) be an order in an algebraic number field, and assume that \(O\) is generated additively by its units. The authors introduce the unit sum height \(\omega(\alpha)\) of \(\alpha\in O\), defined as the smallest integer \(a_1\) such that \(\alpha\) can be written in the form \(\alpha=a_1u_1+\cdots+a_mu_m\) with distinct units \(u_1,\dots,u_m\) and

HARMONIC MAPPINGS WITH THE FIXED ANALYTIC PART
In this article, we consider a class of sense-preserving harmonic mappings whose analytic part is convex in one direction. We prove that functions in this class are close-to-convex for certain values of parameters.

Optimal calibration in immunoassay and inference on the coefficient of variation [PDF]
This thesis examines and develops statistical methods for design and analysis with applications in immunoassay and other analytical techniques. In immunoassay, concentrations of components in clinical samples are measured using antibodies.

Sharp Coefficient Bounds for a Subclass of Bounded Turning Functions with a Cardioid Domain
In the present paper, we give a new simple proof on the sharp bounds of coefficient functionals related to the Carathéodory functions and make a correction on the extremal functions.
