A Method for Temporal Fault Tree Analysis Using Intuitionistic Fuzzy Set and Expert Elicitation
IEEE Access, 2020 Temporal fault trees (TFTs), an extension of classical Boolean fault trees, can model time-dependent failure behaviour of dynamic systems. The methodologies used for quantitative analysis of TFTs include algebraic solutions, Petri nets (PN), and Bayesian

How unprovable is Rabin's decidability theorem?
, 2015 We study the strength of set-theoretic axioms needed to prove Rabin's theorem on the decidability of the MSO theory of the infinite binary tree. We first show that the complementation theorem for tree automata, which forms the technical core of typical ...

An allometry-based approach for understanding forest structure, predicting tree-size distribution and assessing the degree of disturbance [PDF]
, 2012 Tree-size distribution is one of the most investigated subjects in plant population biology. The forestry literature reports that tree-size distribution trajectories vary across different stands and/or species, while the metabolic scaling theory suggests

Scattering of conformal higher spin fields
Journal of High Energy Physics, 2018 We develop a formalism for describing the most general notion of tree-level scattering amplitudes in 4d conformal higher spin theory. As conformal higher spin fields obey higher-derivative equations of motion, there are many distinct on-shell external ...

Notes on the scattering amplitude / Wilson loop duality
, 2010 We consider the duality between the four-dimensional S-matrix of planar maximally supersymmetric Yang-Mills theory and the expectation value of polygonal shaped Wilson loops in the same theory.

MHV Rules for Higgs Plus Multi-Gluon Amplitudes [PDF]
, 2004 We use tree-level perturbation theory to show how non-supersymmetric one-loop scattering amplitudes for a Higgs boson plus an arbitrary number of partons can be constructed, in the limit of a heavy top quark, from a generalization of the scalar graph ...

BCJ numerators from differential operator of multidimensional residue
European Physical Journal C: Particles and Fields, 2020 In previous works, we devised a differential operator for evaluating typical integrals appearing in the Cachazo–He–Yuan (CHY) forms and in this paper we further streamline this method.

A New Method to Identify Incomplete Frame of Discernment in Evidence Theory
IEEE Access, 2019 One assumption of Dempster-Shafer evidence theory (D-S theory) is the closed world. However, how to determine whether the frame of discernment is incomplete or not is still an open issue.

All Split Helicity Tree-Level Gluon Amplitudes
, 2005 Recently a new recursion relation for tree-level gluon amplitudes in gauge theory has been discovered. We solve this recursion to obtain explicit formulas for the closed set of amplitudes with arbitrarily many positive and negative helicity gluons in a ...
