Enhanced thermally-activated skyrmion diffusion with tunable effective gyrotropic force
(2023)Magnetic skyrmions, topologically-stabilized spin textures that emerge in magnetic systems, have garnered considerable interest due to a variety of electromagnetic responses that are governed by the topology. The topology ... -
Search for new heavy resonances decaying to WW, WZ, ZZ, WH, or ZH boson pairs in the all-jets final state in proton-proton collisions at √s=13 TeV
(2023)A search for new heavy resonances decaying to WW, WZ, ZZ, WH, or ZH boson pairs in the all-jets final state is presented. The analysis is based on proton-proton collision data recorded by the CMS detector in 2016-2018 at ... -
Optimization of quasi-hemispherical CdZnTe detectors by means of first principles simulation
(2023)In this paper we present the development of quasi-hemispherical gamma-ray detectors based on CdZnTe. Among the possible single-polarity electrode configurations, such as coplanar, pixelated, or virtual Frisch-grid geometries, ... -
Effect of UV Irradiation on the Growth of ZnO:Er Nanorods and Their Intrinsic Defects
(2023)Nanorods of erbium-doped zinc oxide (ZnO:Er) were fabricated using a hydrothermal method. One batch was prepared with and another one without constant ultraviolet (UV) irradiation applied during the growth. The nanorods ... -
Corpus-Based Multilingual Event-type Ontology: Annotation Tools and Principles
(Association for Computational Linguistics, Washington, D.C., USA, 2023)In the course of building a multilingual Event-type Ontology resource called SynSemClass, it was necessary to provide the maintainers and the annotators with a set of tools to facilitate their job, achieve data format ... -
Time-resolved circular dichroism of excitonic systems: theory and experiment on an exemplary squaraine polymer
(2023)Experimental and theoretical foundations for femtosecond time-resolved circular dichroism (TRCD) spectroscopy of excitonic systems are presented. In this method, the system is pumped with linearly polarized light and the ... -
Interleaflet organization of membrane nanodomains: What can(not) be resolved by FRET?
(2023)Plasma membranes as well as their simplified model systems show an inherent nanoscale heterogeneity. As a result of strong interleaflet interactions, these nanoheterogeneities (called here lipid nanodomains) can be found ... -
Reducing the Cost of Neural Network Potential Generation for Reactive Molecular Systems
(2023)Although machine learning potentials have recently had a substantial impact on molecular simulations, the construction of a robust training set can still become a limiting factor, especially due to the requirement of a ... -
Search for new physics in the τ lepton plus missing transverse momentum final state in proton-proton collisions at √s=13 TeV
(2023)A search for physics beyond the standard model (SM) in the final state with a hadronically decaying tau lepton and a neutrino is presented. This analysis is based on data recorded by the CMS experiment from proton-proton ... -
Search for Z′ bosons decaying to pairs of heavy Majorana neutrinos in proton-proton collisions at √s=13 TeV
(2023)A search for the production of pairs of heavy Majorana neutrinos (N-& ell;) from the decays of Z ' bosons is performed using the CMS detector at the LHC. The data were collected in proton-proton collisions at a center-of-mass ... -
On mechanical twinning in tetragonal lattice
(2023)The theory of mechanical twinning is revisited for the case of face-centred tetragonal lattices. The motivation is an imprecision in the determination of twinning shear vector magnitude, which occurs repeatedly in the ... -
Measurement of Direct-Photon Cross Section and Double-Helicity Asymmetry at √s=510 GeV in (p)over-right-arrow + (p)over-right-arrow Collisions
(2023)We present measurements of the cross section and double-helicity asymmetry ALL of direct-photon production in p ⃗ + p ⃗ collisions at ffis ffi p = 510 GeV. The measurements have been performed at midrapidity (I & eta;I ... -
Uma introdução à análise de massas de ar, frentes e ciclones extratropicais na América do Sul
(2023)Massas de ar, frentes e ciclones extratropicais são sistemas meteorológicos que comumente afetam o tempo na América do Sul, incluindo o Brasil. A passagem de uma frente fria por uma dada região pode causar, por exemplo, ... -
Wet etching of gold on graphene for high-quality resist-free graphene surfaces
(2023)Wet etching of gold on graphene is challenging due to the weak adhesion of the resist mask to graphene. We report an operating procedure for alkali ion-free wet etching of gold on graphene using a mixture of hydrochloric ... -
Laser-induced transient currents in CdZnTe quasi-hemispherical radiation detector
(2023)Laser-induced transient currents were measured after applying pulsed or direct-current bias to a CdZnTe quasi-hemispherical radiation detector with gold contacts. The temporal evolution of current transients was analyzed ... -
Spanish Verbal Synonyms in the SynSemClass Ontology
(Association for Computational Linguistics, Washington, D.C., USA, 2023)This paper presents ongoing work in the expansion of the multilingual semantic event-type ontology SynSemClass (Czech-English-German) to include Spanish. As in previous versions of the lexicon, Spanish verbal synonyms have ... -
Search for Higgs boson and observation of Z boson through their decay into a charm quark-antiquark pair in boosted topologies in proton-proton collisions at √s=13 TeV
(2023)A search for the standard model (SM) Higgs boson (H) produced with transverse momentum (p(T)) greater than 450 GeV and decaying to a charm quark-antiquark (c <overline>c) pair is presented. The search is performed using ... -
Video games and attitude change: A meta-analysis
(2023)Video games are increasingly portraying many topics that we face in our everyday lives. Yet we have only limited evidence about the way narrative games affect how we think about the topics they depict; in other words, about ... -
