On the regularization of extremal three-point functions involving giant gravitons

Physics Letters B, 2015
In the AdS5/CFT4 set-up, extremal three-point functions involving two giant 1/2 BPS gravitons and one point-like 1/2 BPS graviton, when calculated using semi-classical string theory methods, match the corresponding three-point functions obtained in the ...

Failure Analysis for Hydraulic System of Heavy-Duty Machine Tool with Incomplete Failure Data

Applied Sciences, 2021
A hydraulic system is a key subsystem of heavy-duty machine tools with a high failure intensity, the failure of which often causes shutdown of production and economic loss in machining. Therefore, it is necessary to implement failure analysis to identify

Chiral fermions and gauge-fixing in five-dimensional theories [PDF]

, 2001
We study in detail the issue of gauge-fixing in theories with one universal extra dimension, i.e. theories where both bosons and fermions display Kaluza-Klein (KK) excitations.

Multi-decision tree prediction model for coal seam floor water inrush based on cost-sensitive theory

Gong-kuang zidonghua, 2020
When predicting coal seam floor water inrush, the situation is generally divided into two states: safe state and water inrush state. The state data has non-equilibrium characteristics.

A Fuzzy Graph Theory Approach to the Facility Location Problem: A Case Study in the Indian Banking System

Mathematics, 2023
A fuzzy graph G is stated to have a set of trees as its tree cover if all the vertices of G are in their union. The maximum weight tree in the tree cover is assumed to be the cost of a tree cover for a fuzzy graph.

String field theory and brane superpotentials [PDF]

, 2001
I discuss tree-level amplitudes in cubic topological string field theory, showing that a certain family of gauge conditions leads to an A-infty algebra of tree-level string products which define a potential describing the dynamics of physical states ...

Unfolding of Finite Concurrent Automata [PDF]

Electronic Proceedings in Theoretical Computer Science, 2018
We consider recognizable trace rewriting systems with level-regular contexts (RTL). A trace language is level-regular if the set of Foata normal forms of its elements is regular. We prove that the rewriting graph of a RTL is word-automatic.

Excursion theory for Brownian motion indexed by the Brownian tree [PDF]

Journal of the European Mathematical Society (Print), 2015
We develop an excursion theory for Brownian motion indexed by the Brownian tree, which in many respects is analogous to the classical It\^o theory for linear Brownian motion.

Failure Probability Analysis of Coherent Systems using Intuitionistic Fuzzy Fault Tree Approach [PDF]

International Journal of Mathematical, Engineering and Management Sciences
In scenarios where system component failure probabilities are insufficient or imprecise, classical fault tree analysis methods often fail in providing precise assessments of system reliability and safety.

Forwarding-tree Construction and Link Scheduling Algorithm for Data Collection [PDF]

Jisuanji gongcheng, 2017
Most data collection methods based on Compressive Sensing(CS) usually assume that the network has no interference or it can take effective conflict avoidance measures.When these methods are applied to the network with interference or noise,they cannot ...
