Adversarial Examples on Graph Data: Deep Insights into Attack and Defense
Huijun Wu, Chen Wang, Yuriy Tyshetskiy +3
Graph deep learning models, such as graph convolutional networks (GCN) achieve remarkable performance for tasks on graph data. Similar to other types of deep models, graph deep lea…
Efficient Representation Learning Using Random Walks for Dynamic Graphs
Hooman Peiro Sajjad, Andrew Docherty, Yuriy Tyshetskiy
An important part of many machine learning workflows on graphs is vertex representation learning, i.e., learning a low-dimensional vector representation for each vertex in the grap…
Evaluating approaches for supervised semantic labeling
Natalia Ruemmele, Yuriy Tyshetskiy, Alex Collins
Relational data sources are still one of the most popular ways to store enterprise or Web data, however, the issue with relational schema is the lack of a well-defined semantic des…
A new type of surface waves in a fully degenerate quantum plasma
Yuriy Tyshetskiy, Roman Kompaneets, Sergey V. Vladimirov
We study the response of a semi-bounded one-component fully degenerate electron plasma to an initial perturbation in the electrostatic limit. We show that the part of the electric…
Guided modes in a spatially dispersive wire medium slab
Yu. Tyshetskiy, S. V. Vladimirov, A. E. Ageyskiy +3
We study the guided modes in the wire medium slab taking into account both the nonlocality and losses in the structure. We show that due to the fact that the wire medium is an extr…
Soliton solution of the Zakharov equations in quantum plasmas
F. Sayed, S. V. Vladimirov, Yu. Tyshetskiy +1
We investigate the existence of envelope soliton solutions in collisionless quantum plasmas, using the quantum-corrected Zakharov equations in the kinetic case, which describes the…
Comment on "Novel Attractive Force between Ions in Quantum Plasmas" [Shukla, Eliasson, PRL 108, 165007 (2012), arXiv:1112.5556]
Yuriy O. Tyshetskiy, Sergey V. Vladimirov
It is shown that the attractive force between ions in a degenerate quantum plasma, recently predicted by Shukla and Eliasson [Shukla, Eliasson, PRL 108, 165007 (2012), arXiv:1112.5…
Surface plasmon polaritons in a semi-bounded degenerate plasma: role of spatial dispersion and collisions
Yuriy Tyshetskiy, Sergey V. Vladimirov, Roman Kompaneets
Surface plasmon polaritons (SPPs) in a semi-bounded degenerate plasma (e.g., a metal) are studied using the quasiclassical mean-field kinetic model, taking into account the spatial…
Peculiarities of Surface Plasmons in Quantum Plasmas
Yuriy O. Tyshetskiy, Sergey V. Vladimirov, Roman Kompaneets
Surface plasmons (SP) in a semi-bounded quantum plasma with degenerate electrons (e.g., a metal) is considered, and some interesting consequences of electron Pauli blocking for the…
Ion response in a weakly ionized plasma with ion flow
Roman Kompaneets, Yuriy O. Tyshetskiy, Sergey V. Vladimirov
We study the ion response to an initial perturbation in a weakly ionized plasma with ion flow driven by a dc electric field. The analysis is made by extending the classical Landau…
Dispersion and damping of potential surface waves in a degenerate plasma
Yu. O. Tyshetskiy, D. Williamson, R. Kompaneets +1
Potential (electrostatic) surface waves in plasma half-space with degenerate electrons are studied using the quasi-classical mean-field kinetic model. The wave spectrum and the col…
Quantum tunneling-enhanced charging of nanoparticles in plasmas
Yuriy Tyshetskiy, Sergey Vladimirov
The role of quantum tunneling effect in the electron accretion current onto a negatively charged grain immersed in isotropic plasma is analyzed, within the quasiclassic approximati…
Shielding of absorbing objects in collisionless flowing plasma
Yuriy Tyshetskiy, Sergey V. Vladimirov
The electrostatic shielding of a charged absorbing object (dust grain) in a flowing collisionless plasma is investigated by using the linearized kinetic equation for plasma ions wi…
