On a New Integral Inequality: Generalizations and Applications

open access: yesAxioms, 2022
In this paper, we present some generalizations and improvements of a new integral inequality from the 29th IMC in 2022. Some applications of our new results are also provided.

Exponential periods and o-minimality II [PDF]

open access: yesarXiv, 2020
This paper is a sequel to "Exponential periods and o-minimality I" that the authors wrote together with Philipp Habegger. We complete the comparison between different definitions of exponential periods, and show that they all lead to the same notion.

The $C^*$-algebra of the exponential function [PDF]

open access: yesProceedings of the American Mathematical Society, 2013
The complex exponential function is a local homeomorphism and gives therefore rise to an 'etale groupoid and a C*-algebra. We determine this algebra, as well as the alge bra of the complex conjugate of the exponential function.

Exponential Localization of Wannier Functions in Insulators [PDF]

open access: yesPhysical Review Letters, 2007
The exponential localization of Wannier functions in two or three dimensions is proven for all insulators that display time-reversal symmetry, settling a long-standing conjecture. Our proof relies on the equivalence between the existence of analytic quasi-Bloch functions and the nullity of the Chern numbers (or of the Hall current) for the system under

Exponential Functions in Cartesian Differential Categories [PDF]

open access: yesarXiv, 2019
In this paper, we introduce differential exponential maps in Cartesian differential categories, which generalizes the exponential function $e^x$ from classical differential calculus. A differential exponential map is an endomorphism which is compatible with the differential combinator in such a way that generalizations of $e^0 = 1$, $e^{x+y} = e^x e^y$,

The H and J functionals in the theory of complete exponential sums [PDF]

open access: yesarXiv, 2020
In this paper we introduce two nonlinear functionals, the H and J functional, in the theory of complete exponential sums.

Shielding resources for four common radiopharmaceuticals utilized for imaging and therapy: Tc‐99m, F‐18, I‐131, and Lu‐177

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Introduction The use of radioactive materials in the United States has been tightly regulated by the Nuclear Regulatory Commission and other entities for many decades. In 2015, however, the Joint Commission began to require hospital‐based nuclear medicine departments to conduct shielding designs and evaluations for radioactive material areas ...

Research on In-Flight Alignment for Micro Inertial Navigation System Based on Changing Acceleration using Exponential Function

open access: yesMicromachines, 2018
In order to guarantee the stable flight of a guided projectile, it is difficult to realize in-flight alignment for the micro inertial navigation system (MINS) during its short flight time.

Solutions of fractional nabla difference equations - existence and uniqueness [PDF]

open access: yesOpuscula Mathematica, 2016
In this article, we discuss existence, uniqueness and dependency of solutions of nonlinear fractional nabla difference equations in a Banach space equipped with a suitable norm, using the contractive mapping approach. As an application of the established
