Transient Triplet Metallopnictinidenes
(2025-04-30)Nitrenes (N–R) are subvalent key intermediates in organic synthesis and have been extensively studied. The heavier pnictinidene analogues have also attracted great interest, but comprehensive investigations that systematically ... -
Final Steps Towards Production of the ITk Pixel Detector for the ATLAS High Luminosity Upgrade
(2025-04-28)The Large Hadron Collider (LHC) upgrade to the High-Luminosity LHC (HL-LHC) will bring an unprecedentedly challenging environment to the detectors, with an instantaneous luminosity of $5\times10^{34}\,\rm cm^{-2}s^{-1}$, ... -
Sustainable Agri-Food Systems: Climate Change, Food Prices, and Macroeconomic Dynamics
(2025-04-24)Agri-food systems are integral to achieving at least 12 of the 17 Sustainable Development Goals (SDGs). Nevertheless, agri-food systems are both a victim of and contributor to climate change. A comprehensive understanding ... -
Terrestrial Carbon Dynamics under Land Use Transformation in Jambi, Indonesia
(2025-04-23)Tropical forests in Indonesia are rapidly being converted into agricultural systems, particularly oil palm and rubber plantations. These transformations significantly alter carbon dynamics, leading to substantial losses ... -
Untersuchung von Indikatoren zur Einschätzung des Risikos einer Subakuten Pansenazidose bei Milchkühen auf Praxisbetrieben
(2025-04-23)Feeding of high-yielding dairy cows in the beginning of lactation is a major challenge due to high energy requirements and reduced dry matter intake at the same time. This leads to diets with a high level of rapidly ... -
Evolution of polyploidy and apomixis in the pantropically distributed and species-rich genus Zanthoxylum (Rutaceae)
(2025-04-22)The proto-Rutaceae group includes genera with significant economic and evolutionary importance, yet their phylogenetic relationships and evolutionary mechanisms remain incompletely understood. This thesis focuses on the ... -
Understanding the Effective Number of Independent Chromosome Segments as a Tuning Parameter for Genomic Prediction
(2025-04-16)The effective number of independently segregating chromosome segments (𝑀𝑒) is a key parameter in animal selection. Its relevance lies within the methods to obtain the accuracy of genomic prediction. However, there is ... -
Housing pigs with undocked tails: methods for the early detection and prevention of tail biting
(2025-04-15)The occurrence of tail biting is a widespread problem in global pig farming. Painful biting incidents lead to a significant impairment of animal health, animal welfare and the performance of pigs in various production ... -
Small-scale dynamics and large-scale stability of the outer solar atmosphere
(2025-04-14)The Sun has long been utilized as an observatory for gaining a better understanding of high-energy plasma physics. With the advent of the space age and the continual improvement of Sun-observing instruments, physicists ... -
Effect of fragmentation and low density on gene flow and genetic diversity on two conifer species, Pinus gerardiana in Gardiz, Afghanistan, and Taxus baccata in Bavarian Forest National Park, Germany
(2025-04-14)This thesis investigates the genetic diversity, structure, and conservation needs of two coniferous species: Pinus gerardiana and Taxus baccata. Using advanced genetic markers, EST-SSRs and cpSSRs, the study reveals critical ... -
On the ground and above: Forest Composition Effects on Terrestrial and Arboreal Small Mammals and their Consequences for Seed Dynamics
(2025-04-10)1- Forest admixtures and non-native tree species have been increasingly employed in forestry practices as they have the potential to mitigate climate change impacts, enhance biodiversity and yield a greater economic ... -
Integrating Deep Learning Techniques into Trees Outside Forests (TOF) Monitoring by High Resolution Satellite Imagery
(2025-04-08)Trees outside forests (TOF) provide essential ecosystem services and livelihood benefits across diverse landscapes. They are also recognized as important carbon sinks, playing a crucial role in climate change mitigation ... -
Computational Complexity Meets Statistical Efficiency: From Change Point Estimation to Monotonicity Testing
(2025-04-04)In the Information Age, statistical efficiency and computational tractability have become equally important. In this dissertation, we propose two novel statistical procedures: the Fast and Optimal Monotonicity Test (FOMT) ... -
Enantioselective Electrochemical C–H Activation with Cobalt, Nickel, and Iron
(2025-04-04)The enantioselective functionalization of otherwise inert C–H bonds to assemble chiral molecules has become an increasingly powerful tool in molecular synthesis. In spite of significant advances in this domain, the ... -
Role of root exudates as signals in the interaction of Brassica napus L. roots with Verticillium longisporum in the soil
(2025-04-03)Verticillium longisporum is a soil-borne pathogen that primarily infects brassicaceous plants, including oilseed rape, a major global source of vegetable oil and oil extraction meal. V. longisporum causes stem striping ... -
Klimarisikomanagement - Akzeptanz und Potential satellitenbasierter Indexversicherungen in Deutschland
(2025-03-27)Although drought is the most relevant production risk for farmers in Germany, the demand for weather index insurance remains very low. Given that basis risk is known to be one of the main inhibiting factors of farmers’ ... -
Observation of four top quarks production and EFT interpretations in the multi-lepton final state with the ATLAS Experiment
(2025-03-27)The Standard Model has been remarkably successful in describing fundamental particles and their interactions. However its incompleteness makes the search for physics beyond the Standard Model one of the most important ... -
