Elementary Deuring-Heilbronn Phenomenon

, 2012
Adapting a technique of Pintz, we give an elementary demonstration of the Deuring phenomenon: a zero of \zeta(s) off the critical line gives a lower bound on L(1,\chi).

Efficiency analysis of continuous and discontinuous Galerkin finite element methods

AIMS Mathematics
We present a comparative analysis of the continuous Galerkin (CG) and discontinuous Galerkin (DG) finite element (FE) methods, focusing on their efficiency in solving advection–diffusion problems in the Summation By Parts–Simultaneous Approximation Term (

TECHNICAL CONDITION EVALUATION OF CONSTRUCTION MATERIALS OF A TURBO-REFRIGERATION UNIT PARTS OF AN AIRCRAFT AIR CONDITIONING SYSTEM BY CHANGING THE LEVEL OF RESIDUAL STRESSES

Научный вестник МГТУ ГА, 2021
One of the frequent causes of aviation incidents and accidents is the failure of technical equipment and the destruction of aircraft (AC) constructions resulting from unacceptable deformations and structural destruction of the parts operating under high ...

A Polynomial Spectral Calculus for Analysis of DG Spectral Element Methods

, 2017
We introduce a polynomial spectral calculus that follows from the summation by parts property of the Legendre-Gauss-Lobatto quadrature. We use the calculus to simplify the analysis of two multidimensional discontinuous Galerkin spectral element ...

Partial Sums of Two Quartic q-Series

Symmetry, Integrability and Geometry: Methods and Applications, 2009
The partial sums of two quartic basic hypergeometric series are investigated by means of the modified Abel lemma on summation by parts. Several summation and transformation formulae are consequently established.

The Asymptotic Behaviours of a Class of Neutral Delay Fractional-Order Pantograph Differential Equations

Advances in Mathematical Physics, 2017
By using fractional calculus and the summation by parts formula in this paper, the asymptotic behaviours of solutions of nonlinear neutral fractional delay pantograph equations with continuous arguments are investigated.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
