Texture Spectral Similarity Criteria Comparison
Havlíček, Michal; Haindl, Michal
2023 - English
Criteria capable of texture spectral similarity evaluation are presented and compared. From the fifteen evaluated criteria, only four criteria guarantee zero or minimal spectral ranking errors. Such criteria can support texture modeling algorithms by comparing the modeled texture with corresponding synthetic simulations. Another possible application is the development of texture retrieval, classification, or texture acquisition system. These criteria thoroughly test monotonicity and mutual correlation on specifically designed extensive monotonously degrading experiments.

The long-term impact of energy poverty and its mitigation on educational attainment: evidence from China
Martirosyan, Yervand
2023 - English
Existing studies demonstrate the short-run connection between environmental conditions and academic performance. However, the long-term effects of exposure to adverse living conditions on academic achievement remain underexplored. This study investigates the long-term impact of energy poverty, and policy interventions aimed at alleviating it, on the academic performance of Chinese schoolchildren starting from infancy. It specifically utilizes the Huai River Policy, which provides free winter heating exclusively to northern regions in China but not to adjacent southern regions. My findings suggest a significant positive influence of winter heating on schoolchildren’s academic performance, with a more pronounced effect for children born during winter months. The insights gained from this research could inform policy debates to enhance educational outcomes and human well-being.\n

Organoruthenium glycomimetics as selective galectin-1 inhibitors
Hamala, Vojtěch
2023 - English
The prepared organoruthenium glycomimetics demonstrated sin gle unit nanomolar affinity to Gal-1 and over four orders of magnitude\nhigher selectivity to Gal-1 in comparison to Gal-3. The organoruthe nium galectin inhibitors were found to be nontoxic to both cancer and\nnoncancerous cell lines. Selected complexes showed an in vitro an timigratory effect against invasive cancer cell lines MDA-MB-231 and\nSK-OV-3.

The effect of meteorology and aerosol size distribution on light scattering properties at a rural background site in Central Europe
Suchánková, Lenka
2023 - English
The aim of this study is to characterize the light scattering properties of aerosols at the rural background site National Atmospheric\nObservatory Košetice (NAOK; 49°34’20.787”N, 15°4’48.155”E) in Central Europe, namely the coefficients of total light scattering (σsp) and backscattering (σbsp), the Ångström exponent (SAE), the backscattering ratio (b), and the asymmetry factor (g), with special attention to the influence of meteorology and aerosol size distribution on these properties. We measured σ𝑠𝑝 and σ𝑏𝑠𝑝 at three wavelengths (450, 550, and 700 nm) using the Integrating Nephelometer TSI 3563 (PM10 inlet). The measurements were performed from August 16, 2012 to December 31, 2019.

PROCESSING OF THE DATA MEASURED WITH CLOUD CONDENSATION NUCLEI COUNTER IN YEAR 2020 FOR SUBMISSION TO EBAS DATABASE
Moravec, Pavel; Jindra, Tomáš; Wagner, Zdeněk; Ždímal, Vladimír
2023 - English
Aerosol particles in the atmosphere that allow water vapor to condense and form cloud droplets are called Cloud Condensation Nuclei (CCN). Elevated concentrations of CCN tend to increase the concentration and decrease the size of cloud droplets. This can lead to suppression of precipitation in shallow and short-lived clouds and to greater convective overturning and more precipitation in deep convective clouds, Rose et al.(2010). The response of cloud properties and precipitation processes to increasing anthropogenic aerosol concentrations represents one of the largest uncertainties in the current understanding of climate change. One of the fundamental challenges is to determine the ability of aerosol particles to act as CCN under relevant atmospheric conditions. Knowledge of the spatial and temporal distribution in the atmosphere is essential to incorporate the effects of CCN into meteorological models of all scales, Huang et al. (2007). Long-term CCN measurements are performed at aerosol monitoring sites such as those forming ACTRIS (Aerosols, Clouds, and Trace Gases Research Infrastructure) network. Measured data are then submitted to the EBAS database, where they are available for the other ACTRIS researchers. In this paper, we present our experience with the processing of the data measured with CCNC for submission to the EBAS database. The data prepared for submission to EBAS from year 2020 are also presented.
