Dimensional regularization of the spatial wave function for a singular contact interaction in the relativistic schrodinger equation
( Institute of Physics Publishing , 2016 , Conference Paper)Based on our previous work in PRD 89, 125023 (2014), we stress here (for the first time) the regularization of the spatial wave function for the δ-contact interaction within the relativistic Schrodinger equation. The ... -
Directionally sensitive homogeneously weighted moving average control charts
( Wiley , 2021 , Article)One-sided control charts for monitoring changes in the mean level are proposed in this paper. The proposed charts are given in the form of a homogeneously weighted moving average technique that provides efficient monitoring ... -
Disability, depression and somatization in a low back pain population
( Blackwell Publishing Asia , 2006 , Article)Objective: The aim of this study was to determine the prevalence of low back pain (LBP) in a primary care setting population and examine its association with the symptoms of depression and somatization. Methods: This ... -
Discontinuous coupling and transition from synchronization to an intermittent transient chimera state
( Sharif University of Technology , 2021 , Article)Coexistence of coherent and incoherent clusters, called chimera state, has been observed in different coupling configurations. A majority of studies have considered a static scheme for the network. In this paper, synchronization ... -
Disease mapping of Leishmaniasis outbreak in Afghanistan: spatial hierarchical Bayesian analysis
