Composition-Controlled Cu/Cu3N Nanoparticles via Cylindrical Magnetron Sputtering for Multicarbon CO2 Electroreduction

Ronaldo Katuta, Veronika Červenková, Daniil Nikitin, Jan Hanuš et autres

Abstract Electrochemical CO2 reduction (eCO2R) represents an important strategy to mitigate CO2 emissions while yielding value-added multicarbon (C2+) products, such as ethylene and ethanol. Copper nitride (Cu3N) nanoparticles (NPs) have emerged as attractive catalysts for eCO2R; however, their synthesis remains challenging and …

Nonlinear matter power spectrum from relativistic N -body simulations: Λ s CDM versus Λ CDM

Özgür Akarsu, Eleonora Di Valentino, J Vyskočil, A. Emrah Yükselci et autres

We present relativistic $N$-body simulations of a $Λ_{\rm s}$CDM - sign-switching cosmological constant (CC) - scenario under general relativity and compare its nonlinear matter power spectrum to $Λ$CDM at ${z = 15,\,2,\,1,\,0}$, using best-fit parameters from Planck-only and a combined ''full'' dataset. …

Data: Nonlinear Matter Power Spectrum from relativistic N-body Simulations: ΛsCDM versus ΛCDM

Ozgur Akarsu, Eleonora Di Valentino, J Vyskočil, Ezgi Yılmaz et autres

Matter power spectra presented in the associated paper are obtained from the datasets separately generated from N-body simulations with the relativistic code gevolution [1], and from calculations with the linear Boltzmann code CLASS [2], for matching cosmological best-fit parameters and background cosmologies. …

Towards Zero-Shot Camera Trap Image Categorization

J Vyskočil, Lukáš Picek

This paper describes the search for an alternative approach to the automatic categorization of camera trap images. First, we benchmark state-of-the-art classifiers using a single model for all images. Next, we evaluate methods combining MegaDetector with one or more classifiers and Segment …

A Web-Based COVID-19 Tool for Testing Residents in Retirement Homes: Development Study

Mansoor Davoodi, Ana Batista, Adam Mertel, Abhishek Senapati et autres

BACKGROUND: Long-term care facilities have been widely affected by the COVID-19 pandemic. Empirical evidence demonstrated that older people are the most impacted and are at higher risk of mortality after being infected. Regularly testing care facility residents is a practical approach to …

Fine-scale variation in the effect of national border on COVID-19 spread: A case study of the Saxon-Czech border region

Adam Mertel, J Vyskočil, Lennart Schüler, Weronika Schlechte-Wełnicz et autres

The global extent and temporally asynchronous pattern of COVID-19 spread have repeatedly highlighted the role of international borders in the fight against the pandemic. Additionally, the deluge of high resolution, spatially referenced epidemiological data generated by the pandemic provides new opportunities to …

Infrastructure for spatiotemporal exploration of interregional and international interaction of epidemiological data (DEMO PAPER)

Adam Mertel, Wildan Abdussalam, J Vyskočil, Justin M. Calabrese

The recent waves of COVID-19 highlighted the importance of understanding and quantifying spatiotemporal interactions to infer, model, and predict disease spread in real time. In this demonstration paper, we present a robust infrastructure for interactive exploration of interregional and international spatiotemporal interactions …

Feature-Based Multi-Object Tracking With Maximally One Object per Class

Jan Krejčí, Ondřej Straka, J Vyskočil, Miroslav Jiřík et autres

This paper deals with the problem of tracking multiple objects, in which each object is known to belong to a unique class. We follow the tracking by detection paradigm and assume that the object detector provides scores in addition to each detection. …
