Frontiers in Physiology, 2018 Introduction: Focal atrial tachycardia is commonly treated by radio frequency ablation with an acceptable long-term success. Although the location of ectopic foci tends to appear in specific hot-spots, they can be located virtually in any atrial region ...

Computer simulation of channel processes [PDF]
E3S Web of Conferences, 2019 The article discusses the results of numerical studies of flow movement with a sharp change in the channel parameters. The numerical study of the flow in the channels and rivers creates the possibility of a multivariate forecast of channel processes ...

Exact Ising model simulation on a quantum computer [PDF]
Quantum, 2018 We present an exact simulation of a one-dimensional transverse Ising spin chain with a quantum computer. We construct an efficient quantum circuit that diagonalizes the Ising Hamiltonian and allows to obtain all eigenstates of the model by just preparing

Computer Simulation of Asphaltenes
Petroleum Chemistry, 2018 The review describes theoretical approaches based on computer simulations at various levels of details (from quantum chemical calculations to atomistic and coarse-grained models) to study asphaltenes and systems containing asphaltenes. The used methods are described, their advantages and disadvantages are discussed in terms of computational costs and ...

Efficient Algorithms for Universal Quantum Simulation [PDF]
5th International Conference on Reversible Computation (RC 2013),
Victoria, BC, Canada, July 4-5, 2013. Proceedings. Lecture Notes in Computer
Science Volume 7948, 2013, pp 1-10, 2013 A universal quantum simulator would enable efficient simulation of quantum dynamics by implementing quantum-simulation algorithms on a quantum computer. Specifically the quantum simulator would efficiently generate qubit-string states that closely approximate physical states obtained from a broad class of dynamical evolutions.

Instability of Reissner–Nordström black hole in Einstein-Maxwell-scalar theory
European Physical Journal C: Particles and Fields, 2019 The scalarization of Reissner–Nordström black holes was recently proposed in the Einstein-Maxwell-scalar theory. Here, we show that the appearance of the scalarized Reissner–Nordström black hole is closely related to the Gregory-Laflamme instability of ...

Fluid Simulation System Based on Graph Neural Network [PDF]
arXiv, 2022 Traditional computational fluid dynamics calculates the physical information of the flow field by solving partial differential equations, which takes a long time to calculate and consumes a lot of computational resources. We build a fluid simulation simulator based on the graph neural network architecture. The simulator has fast computing speed and low
