Electric-field control of the skyrmion lattice in Cu2OSeO3

Small-angle neutron scattering has been employed to study the influence of applied electric (E-) fields on the skyrmion lattice in the chiral lattice magnetoelectric Cu2OSeO3. In an experimental geometry with the E-field parallel to the [111] axis, and the magnetic field parallel to the [1-10] axis, we demonstrate that the effect of applying an E-field is to controllably rotate the skyrmion lattice around the magnetic field axis. Our results are an important first demonstration for a microscopic coupling between applied E-fields and the skyrmions in an insulator, and show that the general emergent properties of skyrmions may be tailored according to the properties of the host system.Comment: 12 pages, 4 figures, published version (including final proof corrections).

Predicting Tennis Match Outcomes with Network Analysis and Machine Learning

Singles tennis is one of the most popular individual sports in the world. Many researchers have embarked on a wide range of approaches to model a tennis match, using probabilistic modeling, or applying machine learning models to predict the outcome of matches. In this paper, we propose a novel approach based on network analysis to infer a surface-specific and time-varying score for professional tennis players and use it in addition to players\u2019 statistics of previous matches to represent tennis match data. Using the resulting features, we apply advanced machine learning paradigms such as Multi-Output Regression and Learning Using Privileged Information, and compare the results with standard machine learning approaches. The models are trained and tested on more than 83,000 men\u2019s singles tennis matches between the years 1991 and 2020. Evaluating the results shows the proposed methods provide more accurate predictions of tennis match outcome than classical approaches and outperform the existing methods in the literature and the current state-of-the-art models in tennis
