Semantic IDs for Music Recommendation
M. Jeffrey Mei, Florian Henkel, Samuel E. Sandberg +2
Training recommender systems for next-item recommendation often requires unique embeddings to be learned for each item, which may take up most of the trainable parameters for a mod…
Multimodal Stock Price Prediction: A Case Study of the Russian Securities Market
Kasymkhan Khubiev, Mikhail Semenov
Classical asset price forecasting methods primarily rely on numerical data, such as price time series, trading volumes, limit order book data, and technical analysis indicators. Ho…
On Runge type theorems for solutions to strongly uniformly parabolic operators
P. Yu. Vilkov, A. A. Shlapunov
Let be domains in , , such that and the domain have rather regular boundary. We investigate the problem of approxim…
Knowledge Graphs for the Life Sciences: Recent Developments, Challenges and Opportunities
Jiaoyan Chen, Hang Dong, Janna Hastings +6
The term life sciences refers to the disciplines that study living organisms and life processes, and include chemistry, biology, medicine, and a range of other related disciplines.…
Tempo vs. Pitch: understanding self-supervised tempo estimation
Giovana Morais, Matthew E. P. Davies, Marcelo Queiroz +1
Self-supervision methods learn representations by solving pretext tasks that do not require human-generated labels, alleviating the need for time-consuming annotations. These metho…
Topological obstructions to the diagonalisation of pseudodifferential systems
Matteo Capoferri, Grigori Rozenblum, Nikolai Saveliev +1
Given a matrix pseudodifferential operator on a smooth manifold, one may be interested in diagonalising it by choosing eigenvectors of its principal symbol in a smooth manner. We s…
On approximation of solutions to the heat equation from Lebesgue class by more regular solutions
Alexander Shlapunov
Let , , , and be bounded domains in , , such that and the complement $Ω\setminus ω…
Large spectral gap and impurity-induced states in a two-dimensional Abrikosov vortex
A. A. Bespalov, V. D. Plastovets
We study the subgap spectrum of a 2D Abrikosov vortex in an s-wave superconductor in the absence and presence of a point impurity. By solving the Eilenberger equations without impu…
Sharp upper and lower bounds of the attractor dimension for 3D damped Euler-Bardina equations
Alexei Ilyin, Anna Kostianko, Sergey Zelik
The dependence of the fractal dimension of global attractors for the damped 3D Euler--Bardina equations on the regularization parameter and Ekman damping coefficient is…
Geometry controlled superconducting diode and anomalous Josephson effect triggered by the topological phase transition in curved proximitized nanowires
A. A. Kopasov, A. G. Kutlin, A. S. Mel'nikov
We study the key features of the Josephson transport through a curved semiconducting nanowire. Based on numerical simulations and analytical estimates within the framework of the B…
All-dielectric thermonanophotonics
George P. Zograf, Mihail I. Petrov, Sergey V. Makarov +1
Nanophotonics is an important branch of modern optics dealing with light-matter interaction at the nanoscale. Nanoparticles can exhibit enhanced light absorption under illumination…
Unlocking capacities of viral genomics for the COVID-19 pandemic response
Sergey Knyazev, Karishma Chhugani, Varuni Sarwal +19
More than any other infectious disease epidemic, the COVID-19 pandemic has been characterized by the generation of large volumes of viral genomic data at an incredible pace due to…
Robust Orbital Stabilization: A Floquet Theory-based Approach
Christian Fredrik Sætre, Anton S. Shiriaev, Leonid B. Freidovich +2
The design of robust orbitally stabilizing feedback is considered. From a known orbitally stabilizing controller for a nominal, disturbance-free system, a robustifying feedback ext…
Topological transitions in electronic spectra: Crossover between Abrikosov and Josephson vortices
A. V. Samokhvalov, V. D. Plastovets, A. S. Mel'nikov
The electronic structure of a vortex line trapped by a planar defect in a type-II superconductor is analyzed within the Bogoliubov-de Gennes theory. The normal reflection of electr…

The effect of multiple topological transitions for electron-hole excitations is discovered in full shell proximitized semiconducting nanowires with trapped superconducting vortices…
Gradient-Free Methods for Saddle-Point Problem
Aleksandr Beznosikov, Abdurakhmon Sadiev, Alexander Gasnikov
In the paper, we generalize the approach Gasnikov et. al, 2017, which allows to solve (stochastic) convex optimization problems with an inexact gradient-free oracle, to the convex-…
