Quo Vadis, Orthotrichum pulchellum? A Journey of Epiphytic Moss across the European Continent
2022
Orthotrichum pulchellum is a species of epiphytic moss in which a significant expansion from the oceanic part of Europe to the east of the continent has been observed in the recent two decades. The improvement in air quality in Central and Eastern Europe, but also climate change, probably plays a role in this. This study shows what direction of its spreading we can expect in the future. Ecological niche modeling (ENM) is a widespread method to find out species niches in environmental and geographical space, which allows us to highlight areas that have a higher probability of occurrences of the studied species, based on identifying similar environmental conditions to those already known. We …
A gearbox model for processing large volumes of data by using pipeline systems encapsulated into virtual containers
2020
Software pipelines enable organizations to chain applications for adding value to contents (e.g., confidentially, reliability, and integrity) before either sharing them with partners or sending them to the cloud. However, the pipeline components add overhead when processing large volumes of data, which can become critical in real-world scenarios. This paper presents a gearbox model for processing large volumes of data by using pipeline systems encapsulated into virtual containers. In this model, the gears represent applications, whereas gearboxes represent software pipelines. This model was implemented as a collaborative system that automatically performs Gear up (by using parallel patterns…
Crystal structure and Hirshfeld surface analysis of 3-octyl-4-oxo-2,6-bis(3,4,5-trimethoxyphenyl)piperidinium chloride
2018
The title compound was synthesized by a one-pot Mannich condensation reaction. In the crystal, centrosymmetric dimers are linked into layers parallel to (011) by N—H⋯Cl and C—H⋯Cl hydrogen bonds. A Hirshfeld surface analysis indicates that O—H (20.5%) interactions make the largest contribution to the crystal packing.
Crystal structure of chlorido-{4,5-dimeth-oxy-2-[(2,3-η)-2-prop-2-en-1-yl]phenyl-κC (1)}(piperidine-κN)platinum(II) ethanol monosolvate
2014
The title platinum(II) complex shows a trigonal–bipyramidal coordination and intermolecular C—H⋯Cl, C—H⋯π and (C/O)—H⋯O hydrogen bonds.
1,1′-(Diphosphene-1,2-diyl)bis(2,2,6,6-tetramethylpiperidine)
2017
The title compound, C18H36N2P2, crystallizes in the triclinic space groupP-1 with two independent molecules in the asymmetric unit. Both molecules adopt atransconfiguration of the tetramethylpiperidine units along the P=P axis. The crystal packing is stabilized only by van der Waals interactions.
1,1′-[(2,3,5,6-Tetramethyl-1,4-phenylene)bis(methylene)]dipiperidine
2018
The asymmetric unit of the title compound, C22H36N2, comprises one half-molecule, the other half being generated by a center of inversion. The piperidine ring adopts a chair conformation, with the exocyclic N—C bond in an equatorial orientation. A short intramolecular C—H...N hydrogen bond occurs and forms an S(6) motif. No directional interactions beyond van der Waals contacts are observed between the molecules, which form a wave-like supramolecular architecture.
Towards multi-concern software development with Everything-as-Code
2022
As software is becoming a central element in our lives, more and more stakeholders have concerns. Unlike today, when developers stop their coding activities to satisfy these stakeholder concerns, we propose dealing with them as part of the coding workflow, the central element of programmers’ daily duties. This can be achieved by extending the approach that we call Everything-as-Code (EaC) beyond software engineers and operators. peerReviewed

Is there light after depth? Distribution of periphyton chlorophyll and productivity in lake littoral zones
2014
Periphyton and phytoplankton contribute to the base of lake food webs, and both groups of microalgae are influenced by resources and physical forcing. Spatial variation in light availability interacts with the physical dynamics of the water column to create predictable depth gradients in resources and disturbance that may differentially affect periphyton vs phytoplankton. We characterized the depth distribution of chlorophyll and productivity of periphyton on sediments (epipelon) and phytoplankton in the euphotic zones of 13 oligomesotrophic lakes that span a large size gradient (0.017–32,600 km2 ). Epipelic chlorophyll usually increased with depth in the epilimnion. Light was the primary d…
