Europe's lost forests : A pollen-based synthesis for the last 11,000 years
8000 years ago, prior to Neolithic agriculture, Europe was mostly a wooded continent. Since then, its forest cover has been progressively fragmented, so that today it covers less than half of Europe's land area, in many cases having been cleared to make way for fields and pasture-land. Establishing the origin of Europe's current, more open land-cover mosaic requires a long-term perspective, for wh
Astrocytic and neuronal oxidative metabolism are coupled to the rate of glutamate–glutamine cycle in the tree shrew visual cortex
Astrocytes play an important role in glutamatergic neurotransmission, namely by clearing synaptic glutamate and converting it into glutamine that is transferred back to neurons. The rate of this glutamate–glutamine cycle (VNT) has been proposed to couple to that of glucose utilization and of neuronal tricarboxylic acid (TCA) cycle. In this study, we tested the hypothesis that glutamatergic neurotr
A field guide for cancer diagnostics using cell-free DNA : From principles to practice and clinical applications
Recently, many genome-wide profiling studies provided insights into the molecular make-up of major cancer types. The deeper understanding of these genetic alterations and their functional consequences led to the discovery of novel therapeutic opportunities improving clinical management of cancer patients. While tissue-based molecular patient stratification is the gold standard for precision medici
A multi-level model correlation approach for low-frequency vibration transmission in wood structures
The main challenge in predicting structure-borne sound in wood buildings is to accurately model the vibration transmission between the source and the receiving room. Large variations in model parameters make it difficult to predict absolute vibration levels and to make conclusions regarding the relative effects of different designs. A step towards establishing reliable models is to investigate the
The Intelligence Sleeper Who Never Was: Han Fuying and Case 5004
Constraining the magnitude of the Chiral Magnetic Effect with Event Shape Engineering in Pb–Pb collisions at sNN=2.76 TeV
In ultrarelativistic heavy-ion collisions, the event-by-event variation of the elliptic flow v2 reflects fluctuations in the shape of the initial state of the system. This allows to select events with the same centrality but different initial geometry. This selection technique, Event Shape Engineering, has been used in the analysis of charge-dependent two- and three-particle correlations in Pb–Pb
Refined control of cell stemness allowed animal evolution in the oxic realm
Animal diversification on Earth has long been presumed to be associated with the increasing extent of oxic niches. Here, we challenge that view. We start with the fact that hypoxia (
Degradation of Ge subcells by thermal load during the growth of multijunction solar cells
Germanium solar cells are used as bottom subcells in many multijunction solar cell designs. The question remains whether the thermal load originated by the growth of the upper layers of the multijunction solar cell structure affects the Ge subcell performance. Here, we report and analyze the performance degradation of the Ge subcell due to such thermal load in lattice-matched GaInP/Ga(In)As/Ge tri
A gradient-enhanced damage model coupled to plasticity—multi-surface formulation and algorithmic concepts
A non-local gradient-enhanced damage-plasticity formulation is proposed, which prevents the loss of well-posedness of the governing field equations in the post-critical damage regime. The non-locality of the formulation then manifests itself in terms of a non-local free energy contribution that penalizes the occurrence of damage gradients. A second penalty term is introduced to force the global da

Driving for successful change processes in healthcare by putting staff at the wheel
Purpose – The purpose of this paper is to describe five salient factors that emerge in two successful change processes in healthcare. Organizational changes in healthcare are often characterized by problems and solutions that have been formulated by higher levels of management. This top-down management approach has not been well received by the professional community. As a result, improvement proc

Ru-Catalyzed Completely Deoxygenative Coupling of 2-Arylethanols through Base-Induced Net Decarbonylation
Substituted arylethanols can be coupled by using a readily available Ru catalyst in a fully deoxygenative manner to produce hydrocarbon chains in one step. Control experiments indicate that the first deoxygenation occurs through an aldol condensation, whereas the second occurs through a base-induced net decarbonylation. This double deoxygenation enables further development in the use of alcohols a
Biotic and Abiotic Drivers of Peatland Growth and Microtopography : A Model Demonstration
Peatlands are important carbon reserves in terrestrial ecosystems. The microtopography of a peatland area has a strong influence on its carbon balance, determining carbon fluxes at a range of spatial scales. These patterned surfaces are very sensitive to changing climatic conditions. There are open research questions concerning the stability, behaviour and transformation of these microstructures,

Adsorption of CO on the Fe3O4(001) Surface
The interaction of CO with the Fe3O4(001)-(√2 × √2)R45° surface was studied using temperature-programmed desorption (TPD), scanning tunneling microscopy (STM), and X-ray photoelectron spectroscopy (XPS), the latter both under ultrahigh vacuum (UHV) conditions and in CO pressures up to 1 mbar. In general, the CO-Fe3O4 interaction is found to be weak. The strongest adsorption occurs at surface defec
Cutting and Breaking the Embodied Self
This paper analyzes the Cutting and Breaking (C&B) events affecting the tangible aspects of the personal domain, that is to say the body and its parts. The study of the embodied Self, as the affected theme of C&B events, provides a unique opportunity to contribute to the understanding of the conceptualization of the personal domain, as well as providing an additional distinction between cu
The heat is on : Evaluation of workplace heat stress under a changing climate
Background: There are several scientific indications that increasing heat due to climate change is going to become the next big societal and scientific challenge. Climate change is recognized as a significant public health threat. However, there is a lack of research on its impacts on occupational safety and health. Aims and Objectives: The general aim of the research presented in this thesis was
