Greenhouse gas observation network design for Africa

An optimal network design was carried out to prioritise the installation or refurbishment of greenhouse gas (GHG) monitoring stations around Africa. The network was optimised to reduce the uncertainty in emissions across three of the most important GHGs: CO2, CH4, and N2O. Optimal networks were derived using incremental optimisation of the percentage uncertainty reduction achieved by a Gaussian Ba

Topographical Distribution and Spatial Interactions of Innate and Semi-Innate Immune Cells in Pancreatic and Other Periampullary Adenocarcinoma

Background: The clinical management of pancreatic and other periampullary neoplasms remains challenging. In contrast to other cancer types, immunotherapies are largely ineffective, and the reason for the deprived immune response and the immune inhibiting cellular composition is only fragmentarily understood. The aim of this study was to comprehensively map the abundance, topographic distribution a

Development and Validation of CRISPR Activator Systems for Overexpression of CB1 Receptors in Neurons

Gene therapy approaches using viral vectors for the overexpression of target genes have been for several years the focus of gene therapy research against neurological disorders. These approaches deliver robust expression of therapeutic genes, but are typically limited to the delivery of single genes and often do not manipulate the expression of the endogenous locus. In the last years, the advent o

Laser wakefield accelerated electron beams and betatron radiation from multijet gas targets

Laser Plasma Wakefield Accelerated (LWFA) electron beams and efficiency of betatron X-ray sources is studied using laser micromachined supersonic gas jet nozzle arrays. Separate sections of the target are used for the injection, acceleration and enhancement of electron oscillation. In this report, we present the results of LWFA and X-ray generation using dynamic gas density grid built by shock-wav

Measuring power input, power output and energy conversion efficiency in un-instrumented flying birds

Cost of flight at various speeds is a crucial determinant of flight behaviour in birds. Aerodynamic models, predicting that mechanical power (Pmech) varies with flight speed in a U-shaped manner, have been used together with an energy conversion factor (efficiency) to estimate metabolic power (Pmet). Despite few empirical studies, efficiency has been assumed constant across flight speeds at 23%. I

Conscious use of dreams in waking life (Nontherapy setting) for decision-making, problem-solving, attitude formation, and behavioral change

The study explored to what extent dreams have been perceived as being helpful in waking life. More specifically, for "important" waking life (conscious) decisionmaking, the solving of emotional or nonemotional (practical/technical/work-related) problems, forming/changing an attitude about something or somebody, or a conscious behavioral change of the dreamer (N = 667). On a general level, 62,1% of

Novel treatments of glioblastoma in experimental models

One of the major problems with malignant brain tumours, such as glioblastoma multiforme, is that despite being able to remove the major bulk of the tumour through surgery and treating the patients with chemotherapy and radiotherapy, we know that tumour cells have already spread throughout the brain. Furthermore, we now know that the glioblastoma cells effectively suppress the patients’ own anti-tu

Risk Shifting or Risk Management: How do Firms Hedge in Financial Distress?

In this paper we address the question of how firms hedge in financial distress. Using hand-collected data from oil and gas producers, we show thatthe uniquecharacteristic of derivative portfolios in distressed firms is a strategythat involvessold put options. This is puzzling, considering that selling put options amounts to selling insurance, which creates a new liability that distressed firms seeIn this paper we address the question of how firms hedge in financial distress.Using hand-collected data from oil and gas producers, we show that the uniquecharacteristic of derivative portfolios in distressed firms is a strategy thatinvolves sold put options.

Trilobites

Trilobites are marine arthropods that appeared in Cambrian Epoch 2 and became extinct at the end of the Permian. In some Paleozoic deposits, they number among the most abundant macrofossils. Trilobites are important for early Paleozoic biostratigraphy, especially Cambrian.
