On linear functional equations modulo $${\mathbb {Z}}$$ [PDF]

open access: yesAequationes mathematicae, 2021
AbstractIn this paper, we consider the condition$$\sum _{i=0}^{n+1}\varphi _i(r_ix+q_iy)\in {\mathbb {Z}}$$∑i=0n+1φi(rix+qiy)∈Zfor real valued functions defined on a linear spaceV. We derive necessary and sufficient conditions for functions satisfying this condition to be decent in the following sense: there exist functions$$f_i:V\rightarrow {\mathbb ...

SOME RESULTS ON JACK’S LEMMA FOR ANALYTIC FUNCTIONS

open access: yesJournal of Amasya University the Institute of Sciences and Technology, 2022
In this paper, an upper bound will be found for the second coefficient in the Taylor expansion of the analytical function $p(z)$ using the Jack lemma. Also, the modulus of the angular derivative of the $I_{f}(z)=\frac{zp^{\prime }(z)}{p(z)}$ function on ...

Sufficient conditions for starlikeness associated with parabolic region

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
An analytic function f(z)=z+a n+1 z n+1+⋯, defined on the unit disk △={z:|z||w−1|. This class is closely related to the class of uniformly convex functions. Sufficient conditions for function to be in S p are obtained. In particular,

The prognostic value of serum α-klotho in age-related diseases among the US population: A prospective population-based cohort study

open access: yesPreventive Medicine Reports
Objective: α-Klotho is a potential biological marker of aging with satisfactory clinical applicability. However, its prognostic significance in age-related diseases has largely been undermined.

Entire functions of bounded index in frame

open access: yesМатематичні Студії, 2020
We introduce a concept of entire functions having bounded index in a variable direction, i.e. in a frame. An entire function $F\colon\ \mathbb{C}^n\to \mathbb{C}$ is called a function of bounded frame index in a frame $\mathbf{b}(z)$, if~there exists ...

Liver function from Y to Z [PDF]

open access: yesJournal of Clinical Investigation, 2012
In the 1960s, my lab was interested in understanding how bilirubin and other organic anions are transferred from the plasma through the liver cell and into the bile. We performed gel filtration of liver supernatants and identified two protein fractions, designated Y and Z, which bound organic anions including bilirubin, and thus we proposed that they ...

Bounds for the Second Hankel Determinant of Certain Univalent Functions

open access: yes, 2013
The estimates for the second Hankel determinant a_2a_4-a_3^2 of analytic function f(z)=z+a_2 z^2+a_3 z^3+...b for which either zf'(z)/f(z) or 1+zf"(z)/f'(z) is subordinate to certain analytic function are investigated.

Body composition and pulmonary function in Cystic Fibrosis

open access: yesFrontiers in Pediatrics, 2014
Background: Lower body mass index (BMI) is associated with worse pulmonary function in cystic fibrosis (CF). Hypothesis: Lean body mass (LBM) is more strongly associated with pulmonary function than BMI is.Methods: Anthropometrics, body composition by ...

Results on the deficiencies of some differential-difference polynomials of meromorphic functions

open access: yesOpen Mathematics, 2016
In this paper, we study the relation between the deficiencies concerning a meromorphic function f(z), its derivative f′(z) and differential-difference monomials f(z)mf(z+c)f′(z), f(z+c)nf′(z), f(z)mf(z+c).
