Collective topological spin dynamics in a correlated spin glass
Juraj Krempaský, Gunther Springholz, Sunil Wilfred D'Souza +12
The interplay between spin-orbit interaction (SOI) and magnetic order is currently one of the most active research fields in condensed matter physics and leading the search for mat…
Homogenization of the vibro-acoustic transmission on periodically perforated elastic plates interacting with flow
Eduard Rohan, Vladimír Lukeš
We consider acoustic waves propagating in an inviscid fluid interacting with a rigid periodically perforated plate in the presence of permanent flows. The paper presents a model of…
Dependence of the electronic structure of -SiAlON on the (Al,O) concentration and on the temperature
Saleem Ayaz Khan, Ondřej Šipr, Jiří Vackář +1
SiAlON is a prominent example of systems suitable as hosts for creating materials for light-emitting diodes (LEDs). In this work, the electronic structure of a series of semiordere…
Spoken Term Detection and Relevance Score Estimation using Dot-Product of Pronunciation Embeddings
Jan Švec, Luboš Šmídl, Josef V. Psutka +1
The paper describes a novel approach to Spoken Term Detection (STD) in large spoken archives using deep LSTM networks. The work is based on the previous approach of using Siamese n…
Deep LSTM Spoken Term Detection using Wav2Vec 2.0 Recognizer
Jan Švec, Jan Lehečka, Luboš Šmídl
In recent years, the standard hybrid DNN-HMM speech recognizers are outperformed by the end-to-end speech recognition systems. One of the very promising approaches is the grapheme…
Geometry-induced spin-filtering in photoemission maps from WTe surface states
Tristan Heider, Gustav Bihlmayer, Jakub Schusser +5
We demonstrate that an important quantum material WTe exhibits a new type of geometry-induced spin-filtering effect in photoemission, stemming from low symmetry that is respons…
Multitask Detection of Speaker Changes, Overlapping Speech and Voice Activity Using wav2vec 2.0
Marie Kunešová, Zbyněk Zajíc
Self-supervised learning approaches have lately achieved great success on a broad spectrum of machine learning problems. In the field of speech processing, one of the most successf…
Proton reconstruction with the CMS-TOTEM Precision Proton Spectrometer
CMS, TOTEM Collaborations
The Precision Proton Spectrometer (PPS) of the CMS and TOTEM experiments collected 107.7 fb in proton-proton (pp) collisions at the LHC at 13 TeV (Run 2). This paper describ…
Detection of Prosodic Boundaries in Speech Using Wav2Vec 2.0
Marie Kunešová, Markéta Řezáčková
Prosodic boundaries in speech are of great relevance to both speech synthesis and audio annotation. In this paper, we apply the wav2vec 2.0 framework to the task of detecting these…
Linear Transformations for Cross-lingual Sentiment Analysis
Pavel Přibáň, Jakub Šmíd, Adam Mištera +1
This paper deals with cross-lingual sentiment analysis in Czech, English and French languages. We perform zero-shot cross-lingual classification using five linear transformations c…
Algorithm for Finding an Exact Maximum Distance in E2 with Oexp(N) Complexity: Analysis and Experimental Results
Vaclav Skala
This paper describes a novel and fast, simple and robust algorithm with O(N) expected complexity which enables to decrease run time needed to find the maximum distance of two point…
Revisiting Semistrong Edge-Coloring of Graphs
Borut Lužar, Martina Mockovčiaková, Roman Soták
A matching in a graph is {\em semistrong} if every edge of has an endvertex of degree one in the subgraph induced by the vertices of . A {\em semistrong edge-colorin…
A New Formulation for Total Least Square Error Method in d-dimensional Space with Mapping to a Parametric Line
Vaclav Skala
There are many practical applications based on the Least Square Error (LSE) or Total Least Square Error (TLSE) methods. Usually the standard least square error is used due to its s…
Fast O_{expected}(N) Algorithm for Finding Exact Maximum Distance in E^2 Instead of O(N^2) or O(N lg N)
Vaclav Skala
This paper describes novel and fast, simple and robust algorithm with O(N) expected complexity which enables to decrease run-time needed to find an exact maximum distance of two po…
New Geometric Continuity Solution of Parametric Surfaces
Vaclav Skala
This paper presents a new approach to computation of geometric continuity for parametric bi-cubic patches, based on a simple mathematical reformulation which leads to simple additi…
A New Approach to Line-Sphere and Line-Quadrics Intersection Detection and Computation
Vaclav Skala
Line intersection with convex and un-convex polygons or polyhedron algorithms are well known as line clipping algorithms and very often used in computer graphics. Rendering of geom…
Point-in-Convex Polygon and Point-in-Convex Polyhedron Algorithms with O(1) Complexity using Space Subdivision
Vaclav Skala
There are many space subdivision and space partitioning techniques used in many algorithms to speed up computations. They mostly rely on orthogonal space subdivision, resp. using h…
Transformer-based Automatic Speech Recognition of Formal and Colloquial Czech in MALACH Project
Jan Lehečka, Josef V. Psutka, Josef Psutka
Czech is a very specific language due to its large differences between the formal and the colloquial form of speech. While the formal (written) form is used mainly in official docu…
Field-induced ultrafast modulation of Rashba coupling at room temperature in ferroelectric -GeTe(111)
Geoffroy Kremer, Julian Maklar, Laurent Nicolaï +11
Rashba materials have appeared as an ideal playground for spin-to-charge conversion in prototype spintronics devices. Among them, -GeTe(111) is a non-centrosymmetric ferroelectr…
