Investigating Stock Market Crashes Using Cusp Model: A Study on Tehran Stock Exchange [PDF]
Faslnāmah-i Pizhūhish/Nāmah-i Iqtisādī, 2012 Stock market crashes are important, both for investors and academics. Since Catastrophe Theory is a strong tool for explaining nonlinear phenomena, in this paper we apply Catastrophe theory and fit stochastic Cusp Catastrophe model to Tehran Stock ...

Multiple-Event Catastrophe Bond Pricing Based on CIR-Copula-POT Model
Discrete Dynamics in Nature and Society, 2018 Catastrophe events are attracting increased attention because of their devastating consequences. Aimed at the nonlinear dependency and tail characteristics of different triggered indexes of multiple-event catastrophe bonds, this paper applies Copula ...

MathematicsWhen catastrophe theory is applied to the experimental modeling of catastrophe phenomena, it is impossible to know in advance the corresponding relationship and mapping form between the parameters of the actual catastrophe mathematical model and the ...

Physics Letters B, 2014 We introduce the basic concepts of catastrophe theory needed to derive analytically the phase diagram of the proton–neutron interacting boson model (IBM-2). Previous studies [1–3] were based on numerical solutions.

CATASTROPHE THEORY AND ITS APPLICATION IN ECONOMICS [PDF]
فصلنامه پژوهشهای اقتصادی ایران, 2002 Sudden jumps, qualitative changes and discontinuities are not rare in social and economic phenomena. Catastrophe theory is a proper approach to modeling of dynamical systems that a company faces with sudden jump.

Nonlinear Analysis on Traffic Flow Based on Catastrophe and Chaos Theory
Discrete Dynamics in Nature and Society, 2014 We applied catastrophe and chaos theory to analyze the traffic nonlinear characteristics of expressway condition. Catastrophe theory was generally used to explore the mathematical relationships among the traffic data collected from highway conditions ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes
FEBS Open Bio, EarlyView.Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows
Advanced Engineering Materials, EarlyView.A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Optical catastrophes of the swallowtail and butterfly beams
New Journal of Physics, 2017 We experimentally realize higher-order catastrophic structures in light fields presenting solutions of the paraxial diffraction catastrophe integral. They are determined by potential functions whose singular mapping manifests as caustic hypersurfaces in ...
