A New Extended Mixture Model of Residual Lifetime Distributions
M. Kayid, S. Izadkhah
In this paper, we first propose a new extended mixture model of residual lifetime distributions. We show that this model is suitable in modeling residual lifetime in some practical…
Probing the Top Quark Flavour-Changing Neutral Current at a Future Electron-Positron Collider
Hoda Hesari, Hamzeh Khanpour, Morteza Khatiri Yanehsari +1
We present a study to examine the sensitivity of a future collider to the anomalous top flavour-changing neutral current (FCNC) to the gluon. To separate signal from…
Hydrostatic pressure induced transition from δTc to δl pinning mechanism in MgB2
Babar Shabbir, Xiaolin Wang, S. R. Ghorbani +1
The impact of hydrostatic pressure up to 1.2 GPa on the critical current density (Jc) and the nature of the pinning mechanism in MgB2 have been investigated within the framework of…
Mixed r-stirling numbers of the second kind
Daniel Yaqubi, Madjid Mirzavaziri, Yasin Saeednezhad
The Stirling number of the second kind counts the number of ways to partition a set of labeled balls into non-empty unlabeled cells. As an extension of this, we…
Stable solitary waves in Super dense plasmas at external magnetic fields
Azam Ghaani, Kurosh Javidanyand, Mohsen Sarbishaei
Propagation of localized waves in a Fermi-Dirac distributed super dense matter at the presence of strong external magnetic fields is studied using the reductive perturbation method…
Permutation-Based Tests of Perfect Ranking
Ehsan Zamanzade, Nasser Reza Arghami, Michael Vock
We improve three tests of perfect ranking in ranked set sampling proposed by Li and Balakrishnan (2008) using a permutation approach. This simple way of extending all three concept…
On dynamic mutual information for bivariate lifetimes
Jafar Ahmadi, Antonio Di Crescenzo, Maria Longobardi
We consider dynamic versions of the mutual information of lifetime distributions, with focus on past lifetimes, residual lifetimes and mixed lifetimes evaluated at different instan…
Holographic Two-Point Functions in Conformal Gravity
Ahmad Ghodsi, Behnoush Khavari, Ali Naseh
In this paper we compute the holographic two-point functions of four dimensional conformal gravity. Precisely we calculate the two-point functions for Energy- Momentum (EM) and Par…
Coverage Region Analysis for MIMO Amplify-and-Forward Relay Channel with the Source to Destination Link
Behrooz Razeghi, Ghosheh Abed Hodtani, Seyed Alireza Seyedin
In this paper we study and analyze coverage region for half-duplex multiple-input multiple-output (MIMO) relay channel with amplify-and-forward (AF) strategy at the relay station.…
Reverses of the Young inequality for matrices and operators
Mojtaba Bakherad, Mario Krnic, Mohammad Sal Moslehian
We present some reverse Young-type inequalities for the Hilbert-Schmidt norm as well as any unitarily invariant norm. Furthermore, we give some inequalities dealing with operator m…
Complementary and refined inequalities of Callebaut inequality for operators
M. Bakherad, M. S. Moslehian
The Callebaut inequality says that \begin{align*} \sum_{ j=1}^n \left(A_j\sharp B_j\right)\leq \left(\sum_{ j=1}^n A_j σB_j\right)\sharp\left(\sum_{ j=1}^n A_j σ^{\bot} B_j\right)\…
Planet-vortex interaction:How a vortex can shepherd a planetary embryo
S. Ataiee, C. P. Dullemond, W. Kley +2
Context: Anticyclonic vortices are considered as a favourable places for trapping dust and forming planetary embryos. On the other hand, they are massive blobs that can interact gr…
Some generalized numerical radius inequalities for Hilbert space operators
Mostafa Sattari, Mohammad Sal Moslehian, Takeaki Yamazaki
We generalize several inequalities involving powers of the numerical radius for product of two operators acting on a Hilbert space. For any suc…
Interaction of sine-Gordon kinks and breathers with a -symmetric defect
Danial Saadatmand, Sergey V. Dmitriev, Denis I. Borisov +1
The scattering of kinks and low-frequency breathers of the nonlinear sine-Gordon (SG) equation on a spatially localized -symmetric perturbation (defect) with a balanc…
More on Five Dimensional EVH Black Rings
Ahmad Ghodsi, Hanif Golchin, M. M. Sheikh-Jabbari
In this paper we continue our analysis of arXiv:1308.1478[hep-th] and study in detail the parameter space of three families of doubly spinning black ring solutions: balanced black…
A Generalized Write Channel Model for Bit-Patterned Media Recording
Sima Naseri, Somaie Yazdani, Behrooz Razeghi +1
In this paper, we propose a generalized write channel model for bit-patterned media recording by considering all sources of errors causing some extra disturbances during write proc…
