Radius of Starlikeness of Certain Analytic Functions [PDF]

arXiv, 2020
This paper studies analytic functions $f$ defined on the open unit disk of the complex plane for which $f/g$ and $(1+z)g/z$ are both functions with positive real part for some analytic function $g$. We determine radius constants of these functions to belong to classes of strong starlike functions, starlike functions of order $\alpha$, parabolic ...

Functions that preserve totally bounded sets vis-á-vis stronger notions of continuity [PDF]

arXiv, 2020
A function between two metric spaces is said to be totally bounded regular if it preserves totally bounded sets. These functions need not be continuous in general. Hence the purpose of this article is to study such functions vis-\'a-vis continuous functions and functions that are stronger than the continuous functions such as Cauchy continuous ...

Surface strain at the cervical area and fracture strength of flared root canals reinforced using a zirconia tube and glass-fiber post

Journal of Dental Sciences
Background/purpose: Recently, an effective core build-up system for teeth with flared root canals is needed. This research aimed to evaluate the effect of foundation restorations using a composite resin core with a fiber post reinforced with a zirconia ...

Convergence of Infinite Composition of Entire Functions [PDF]

arXiv, 2010
The purpose of the present article is to obtain the condition that the function defined by infinite composition of entire functions becomes an entire function. Moreover, as an example of such functions, we study a function called Poincare function.

Effects of immersion in 4-methacryloyloxyethyl trimellitate anhydride/methyl methacrylate-tri-n-butyl borane resin-activated liquid on microtensile bond strength of root canal dentin

Journal of Dental Sciences
Background/purpose: 4-methacryloyloxyethyl trimellitate anhydride/methyl methacrylate-tri-n-butyl borane (4-META/MMA-TBB) resin is used for indirect restorations.

Operator $k$-tone functions and analytic functional calculus [PDF]

arXiv, 2015
Operator $k$-tone functions on an open interval of the real line, which are higher order extensions of operator monotone and convex functions, are characterized via certain inequalities for the real and imaginary parts of analytic functional calculus by those functions.

Marginal fit and retention force of zirconia resin-bonded fixed dental prostheses in the posterior region with different designs

Journal of Dental Sciences
Background/purpose: Retainer debonding of resin-bonded fixed dental prostheses (RBFDPs) is one of the major reasons for their lower survival rates than fixed dental prostheses (FDPs) with full-coverage crowns.

Effect of masticatory training using confectioneries on oral function in elderly patients – A randomized controlled trial

Journal of Dental Sciences, 2022
Background/purpose: The number of patients with oral hypofunction is increasing with the aging of the population, and such hypofunction increases their risk for dysphagia and malnutrition.

Masticatory ability with depression, anxiety, and stress: Does there exist any association?

Dental Research Journal, 2016
Background: Masticatory ability as a subjective response to masticatory function indicates patients′ perception of their mastication. To the best of our knowledge, there has been no study on association between masticatory ability and psychological ...
