The ratio of leaf carotenoid to chlorophyll (Car/Chl) is an indicator of vegetation photosynthesis, development and responses to stress. However, the correlation between Car and Chl, and their overlapping absorption in the visible spectral domain pose a challenge for optical remote sensing of their ratio. This study aims to investigate combinations of vegetation indices (VIs) to minimize the influ
Complex scientific questions often require collaboration between scientists to access scientific instruments (deS. Price, Res Policy 13:3–20, 1984; Shrum et al. 2007, Structures of scientific collaboration, The MIT Press, 2007), knowledge and social capital from scientists outside of their immediate networks (Burt, Am J Sociol 110:349–399, 2004; Collins, Tacit and explicit knowledge, University of
Based on nucleotide sequences from three chloroplast DNA regions (rps16, rpl16, trnT-trnL), we infer detailed phylogenetic relationships within the subfamily Thunbergioideae (Acanthaceae) and among major lineages of the family as a whole. Taxa were sampled to cover the geographic distribution of Thunbergioideae and to include all subgenera of the largest genus Thunbergia. All other major lineages
Soil erosion is a critical process influencing the global carbon cycle. However, erosion-induced carbon changes remain inadequately understood, particularly for soil inorganic carbon (SIC). There is also limited knowledge about the factors influencing soil carbon dynamics during erosion processes. Here we quantify the global translocation of soil organic carbon (SOC) and SIC due to soil erosion us
The authors, Gigi Argyropoulou, Ethel Baraona and Lisa Maillard, Elke Krasny and Svetlana Milevska, were invited to write new texts attempting to revisit the concept of care and its discontents. In their texts, they reflect upon understandings of the fundamental role of care, in relation to contradictions of social cohesion and social emancipation, while issues such as the Global South, feminism,
If there were no Coulomb interaction among electrons, it would be relatively straightforward to solve the many-electron Schrödinger equation. It is, however, precisely this interaction that is at the heart of numerous fascinating phenomena in condensed matter physics such as superconductivity, Kondo physics, magnetism, etc. Due to the large number of electrons in a material being of the order of A
This paper introduces heat semigroups of topological Markov chains and Cuntz–Krieger algebras by means of spectral noncommutative geometry. Using recent advances on the logarithmic Dirichlet Laplacian on Ahlfors regular metric-measure spaces, we construct spectral triples on Cuntz–Krieger algebras from singular integral operators. These spectral triples exhaust odd K-homology and for Cuntz algebra
Extreme nuclear shapes are considered from the clustering point of view. General aspects of light nuclei which possess very exotic, elongated shapes ("α-strings") are given. The relation between superdeformation and di-molecules is considered, and it is shown that nuclear di-molecules have the same magic numbers and orbits filled as the ellipsoidal superdeformations for light nuclei, while for hea
Multimedia environments consist of verbal and visual representations that, if appropriately processed, allow for the construction of an integrated mental model of the content. Whereas much is known on how students learn from verbal representations, there are fewer insights regarding the processing of visual information, alone or in conjunction with text. This chapter uses a semiotics approach to p
This report presents findings from the case study on food sharing in the city of Milan, Italy, which was performed as part of the project CULTIVATE: Co-designing Food Sharing Innovation for Resilience: https://cultivate-project.eu/ in June 2024 - November 2024. The study aims to understand the economic, social, and environmental aspects of FSIs, which include growing and composting together, cooki
This paper presents experimental and numerical investigations of liquid droplet/air two-phase flow through face masks. The study aims to provide a deeper understanding of the droplet filtration process, generate experimental data for modeling droplet/air two-phase flow across face masks, and develop and validate numerical models to simulate droplet motion through the mask and downstream. Droplet i
This study investigates isoprene emissions in a high-latitude Alpine tundra ecosystem, focusing on using near-field remote sensing of surface temperatures, the photochemical reflectance index (PRI) and normalized difference vegetation index (NDVI), and meteorological measurements to model these emissions. Isoprene is a key biogenic volatile organic compound (BVOC) emitted by select plants, which c
To improve gearset performance, gears can be subjected to surface treatments. One possible surface treatment is TCG, Triboconditioning for Complex Geometries. This paper investigates efficiency and pitting resistance of two types of TCG treatments on powder-sintered gears, compared to an untreated reference. Experimental testing is performed in an FZG gear test rig with an efficiency and a pitting
Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, is primarily known as a respiratory disease. The continued study of the disease has shown that long-term COVID-19 symptoms include persisting effects of the virus on the brain when the infection is over, possibly even leading to neurodegeneration. However, the exact mechanisms of
