Economic implications of tree species composition and structural diversity in European beech stands enriched with coniferous trees
(2024-09-27)Central European forests are the result of centuries of human activity. Changes in species composition, mainly by introducing conifers to areas outside their native range, mostly Norway spruce (Picea abies [L.] Karst.; ... -
Inter and intra-specific interaction effects on individual tree architecture and stand structure, and consequences for ecosystem functions in mixed forests
(2024-09-27)Central Europe is predicted to experience an increase in temperatures and storm frequency and intensity, which will impact forest ecosystems directly and in interaction. European forests host a large share of Europe’s ... -
Inferring atomic line parameters from solar spectra
(2024-09-19)The proximity of the Earth to the Sun offers a unique opportunity to study different plasma phenomena that occur in its atmosphere, which are unattainable in plasma laboratories. Advances in the instruments used for solar ... -
Higher Currents for the sine-Gordon Model in perturbative Algebraic Quantum Field Theory
(2024-09-19)The main results of this thesis are the establishment of the super-renormalizability by power counting and of the summability of an infinite number of (classically conserved) higher currents for the sine-Gordon model in ... -
Metallaelectro-Catalysis and Aryl Sulfonium Salts in Sustainable C–H Activations and Late-Stage Diversification
(2024-09-17)In the past decades, organic chemistry was dominated by functional group interconversions and cross-coupling chemistry. These techniques allowed the synthesis of a plethora of highly complex molecules and are established ... -
Specification of Multiple Processes in Metacontrast Masking
(2024-09-13)Metacontrast masking has been widely used as a tool to study visual perception, but there is still no comprehensive theory of the phenomenon. There is no lack of theories, but a synthesis of the different approaches seems ... -
High-resolution analysis of regulatory interactions and nano-scale chromatin structures
(2024-09-11)Despite having the same genetic blueprint, the development of a complex, multicellular organism from a single fertilized egg results in a wide variety of hundreds distinct cell types, each uniquely contributing to the ... -
Soil food webs change with land use: basal resources, functional diversity and trophic niche breadth
(2024-09-06)The diversity and interactions of organisms, along with ecosystem functions and stability, are intricately linked to food webs. Among these, soil food webs have only been investigated relatively recently due to the small ... -
Community dynamics and trophic niches of soil fauna in Central European forests
(2024-09-06)Global change is altering the state of forest ecosystems, threatening their integrity. A number of studies have reported declines in aboveground arthropod diversity over the last decade and indicated management practices ... -
Sensory Attenuation related to Action-effect Prediction and the Sense of Agency
(2024-09-03)Sensory consequences caused by a self-generated action (action-effect) are assumed to lead to less intense perception compared to external stimuli. This reduced perception referred to as sensory attenuation is suggested ... -
Iterative helioseismic holography
(2024-08-28)The understanding of the solar interior, in particular the subsurface solar flows, is im- portant for understanding the solar activity cycle. Traditional local helioseismology does not use all the seismic information ... -
Investigation of vibrational dynamics in alcohol-acid complexes and of monohydrates via FTIR and Raman spectroscopy
(2024-08-27)The vibrational dynamics of complexes between carboxylic acids with alcohols is investigated using Raman and FTIR jet spectroscopy combined with quantum chemical calculations. These complexes bind via intermolecular ... -
Enabling Novel Fluoroalkylation via Sulfonium Salt Transfer Reagents
(2024-08-26)Over the past four decades, sulfonium salt-based transfer reagents have evolved into widely recognized tools for fluoroalkylation in the synthetic chemistry community. These reagents have enabled the incorporation of various ... -
Investigation of boundary layer transition at high Reynolds numbers using time-resolved temperature-sensitive paint
(2024-08-23)Understanding the fundamental principles of the processes that lead to laminar-turbulent transition on aerodynamic surfaces is of significant importance to correctly describe, model and perhaps ultimately influence the ... -
Radio-frequency controlled low-energy electron pulses
(2024-08-23)Electron beams are invaluable for probing material structures and dynamic processes due to their large scattering cross sections and the versatility of tunable electron optics for diffraction and microscopy. Pulsed electron ... -
Development of Bone Adhesive Materials based on Collagen-mimetic Peptides and Carbene-mediated Diazirine Crosslinkers
(2024-08-22)Traditional mechanical fixation methods such as screws, support plates, staples, and sutures remain predominant in treating bone trauma. However, these methods can cause localized tissue damage, leading to infection and ... -
On Combinatorial Properties of Subsequences
(2024-08-22)A word, also known as string, is a sequence of letters, while a subsequence of a word w is another word u which can be obtained by deleting some of the letters of w. Words in general, and subsequences in particular, play ... -
