Inferences of the Multicomponent Stress–Strength Reliability for Burr XII Distributions

open access: yesMathematics, 2022
Multicomponent stress–strength reliability (MSR) is explored for the system with Burr XII distributed components under Type-II censoring. When the distributions of strength and stress variables have Burr XII distributions with common or unequal inner ...

Maximum Likelihood Estimation for the Fractional Vasicek Model

open access: yesEconometrics, 2020
This paper estimates the drift parameters in the fractional Vasicek model from a continuous record of observations via maximum likelihood (ML). The asymptotic theory for the ML estimates (MLE) is established in the stationary case, the explosive case ...

Maximum Likelihood Estimation for Mixed Fractional Vasicek Processes

open access: yesFractal and Fractional, 2022
In this paper, we consider the problem of estimating the drift parameters in the mixed fractional Vasicek model, which is an extended model of the traditional Vasicek model.

Asymptotic States in Non-Local Field Theories [PDF]

open access: yes, 1996
Asymptotic states in field theories containing non-local kinetic terms are analyzed using the canonical method, naturally defined in Minkowski space. We apply our results to study the asymptotic states of a non-local Maxwell-Chern-Simons theory coming ...

New determination of structure parameters in strong field tunneling ionization theory of molecules [PDF]

open access: yes, 2010
In the strong field molecular tunneling ionization theory of Tong et al. [Phys. Rev. A 66, 033402 (2002)], the ionization rate depends on the asymptotic wavefunction of the molecular orbital from which the electron is removed.

Black Hole Entropy Associated with Supersymmetric Sigma Model [PDF]

open access: yes, 2003
By means of an identity that equates elliptic genus partition function of a supersymmetric sigma model on the $N$-fold symmetric product $S^N X$ of $X$ ($S^N X=X^N/S_N$, $S_N$ is the symmetric group of $N$ elements) to the partition function of a second ...

Black Hole Microstates and Attractor Without Supersymmetry [PDF]

open access: yes, 2006
Due to the attractor mechanism, the entropy of an extremal black hole does not vary continuously as we vary the asymptotic values of various moduli fields.
