Complex Garnets: Microscopic Parameters Characterizing Afterglow
The Journal of Physical Chemistry C, 2019 Light yield, time response, afterglow, and thermoluminescence of Ce-doped garnet scintillators and persistent luminescent materials are controlled by a complex interplay between recombination and trapping/detrapping processes. Extensive research has contributed to a good qualitative understanding of how traps, impurities, and the presence of Ce4 ...

Prototype selection for parameter estimation in complex models
, 2012 Parameter estimation in astrophysics often requires the use of complex physical models. In this paper we study the problem of estimating the parameters that describe star formation history (SFH) in galaxies.

On the complex Łojasiewicz inequality with parameter [PDF]
Kodai Mathematical Journal, 2018 We prove a continuity property in the sense of currents of a continuous family of holomorphic functions which allows us to obtain a ojasiewicz inequality with an effective exponent independent of the parameter.

Deep learning prediction of amplitude death
Autonomous Intelligent Systems, 2022 Affected by parameter drift and coupling organization, nonlinear dynamical systems exhibit suppressed oscillations. This phenomenon is called amplitude death. In various complex systems, amplitude death is a typical critical phenomenon, which may lead to

Dynamics of the Kuramoto-Sakaguchi Oscillator Network with Asymmetric Order Parameter
, 2018 We study the dynamics of a generalized version of the famous Kuramoto-Sakaguchi coupled oscillator model. In the classic version of this system, all oscillators are governed by the same ODE, which depends on the order parameter of the oscillator ...

Hyperbolic Structures and Root Systems [PDF]
, 2010 We discuss the construction of a one parameter family of complex hyperbolic structures on the complement of a toric mirror arrangement associated with a simply laced root system.

Complex-Parameter Integral Iterations of Caratheodory Maps
Tamkang Journal of Mathematics, 2020 Recent studies in the class of Bazilevi$\check{c}$ maps as a whole has compelled the development, in this work, of certain complex-parameter integral iterations of Caratheodory maps. The iterations are employed in a similar manner as in \cite{BA} to study a certain subfamily of those Bazilevi$\check{c}$ maps.

Local Fourier Analysis of the Complex Shifted Laplacian preconditioner for Helmholtz problems
, 2013 In this paper we solve the Helmholtz equation with multigrid preconditioned Krylov subspace methods. The class of Shifted Laplacian preconditioners are known to significantly speed-up Krylov convergence.

H‐function with complex parameters I: existence [PDF]
International Journal of Mathematics and Mathematical Sciences, 2001 An H‐function with complex parameters is defined by a Mellin‐Barnes type integral. Necessary and sufficient conditions under which the integral defining the H‐function converges absolutely are established. Some properties, special cases, and an application to integral transforms are given.

The complex gradient inequality with parameter [PDF]
, 2014 We prove that given a holomorphic family of holomorphic functions with isolated singularities at zero and constant Milnor number, it is possible to obtain the gradient inequality with a uniform exponent.Comment: A remark was added at the end and some ...
