Preference of dairy cows with free access to pasture and barn
(2024-12-12)With the increasing interest of various consumer groups in high welfare husbandry and the pressure on farmers to meet this demand, the number of comparative studies on dairy cow grazing and housing has also increased. ... -
Evaluating the potential of I-type cosmic spherules as a proxy for the Δ’17O of atmospheric O2 for reconstructing paleo-CO2 levels and GPP throughout the Phanerozoic
(2024-12-09)Entirely molten micrometeorites, termed I-type cosmic spherules, are micrometer to millimeter-sized remnants of extraterrestrial Fe, Ni-rich metal that can be recovered on Earth. I-type cosmic spherules acquire all oxygen ... -
Analysing the Effects of Social Protection Policies on Climate Change Adaptation, Food and Nutrition Security
(2024-12-09)Social protection is gaining recognition as a strategy to address various underlying causes of poverty in developing countries, with increasing population coverage and social protection systems more frequently becoming ... -
Aspects of Temporal Patient Similarity in Complex Diseases
(2024-12-09)When comparing patients with complex chronic diseases, such as cancer or Post COVID-19, in Real-World Data (RWD) it is crucial to consider not only their condition at the time point of analysis but also their disease ... -
Betriebswirtschaftliche Auswirkungen von Alternativen zur betäubungslosen Ferkelkastration
(2024-12-09)Piglet castration without anaesthesia has long been a common practice in pig farming to avoid boar taint in meat and to produce a homogeneous carcass. Due to the growing societal awareness of animal welfare, this practice ... -
Dynamics of Phosphorus Availability and Uptake in Hydroponics and Soils
(2024-12-09)The availability of phosphorus (P) in terrestrial ecosystems is primarily determined by plant genotypes and soil physiochemical characteristics that influence the chemical forms of P in soil and its biotransformation by ... -
C*-algebras of relatively proper groupoid correspondences
(2024-12-09)The objective of the work is to study C*-algebras associated to relatively proper groupoid correspondences, in particular exploring two constructions and proving that they are isomorphic. We also explore some properties ... -
Statistical Limit Laws for Graph Cuts and Efficient Surrogate Algorithms
(2024-12-05)Graph cuts are a powerful tool that has been used in many applications, from image segmentation and machine learning to network analysis and cluster identification, often in the form of a convex relaxation such as spectral ... -
The dual role of MTG3 during human mitoribosome biogenesis
(2024-12-05)Mitochondria are the main energy provider of the cell, and because of the endosymbiotic event they arise from, still contain a small independent genome. Only with the vast ATP production through the mitochondrial OXPHOS ... -
Molecularly Imprinted Polymers via RAFT Polymerisation for Biological Applications
(2024-12-03)Antibodies are of great importance in therapeutic, diagnostic and research fields. Producing antibodies synthetically has been a longstanding goal of researchers and may be achieved using molecularly imprinted polymers ... -
Evaluation of a new VUV-FEL surface science end station using atomic beam surface scattering and velocity-resolved surface reaction dynamics
(2024-12-03)Abstract: 1. Atomic oxygen scattering from HOPG It has been unequivocally established that the electronic spin of a molecule significantly influences reactivity in gas phase reactions. However, the presence of clear ... -
Computational Analysis of Prognostic Factors, Immune Microenvironment, and T-Cell Receptor Repertoires in Lymphoma
(2024-11-22)The immune system plays an important role in the development and progression of cancer. While solid cancers like carcinomas primarily affect specific organs and tissues, hematologic malignancies are not always so localized, ... -
Comparative analyses of stress-induced dynamics in global differential gene expression across more than 550 million years of streptophyte evolution
(2024-11-22)The transition from aquatic to terrestrial habitats was a major evolutionary step in the evolution of plants. It ushered in the birth of embryophytes. This transition occurred before the last common ancestor (LCA) of land ... -
Modeling and Optimization of Animal Breeding Programs
(2024-11-22)Simulation software can be used to model and optimize breeding programs. In the current work, the “Modular Breeding Program Simulator” (MoBPS) was applied to demonstrate this on three examples from layer, horse and pig ... -
