Harris, J. Scott Hosking, Alastair C. Lewis, Olaf Morgenstern, Thomas Peter, John A. Pyle, Thomas Reddmann, N.A.D. Richards, Paul J. Telford, W. Tian, Silvia Viciani, Andreas Volz-Thomas, Oliver Wild, X. Yang … & G. Zeng
The tropical transport processes of 14 different models or model versions were compared, within the framework of the SCOUT-O3 (Stratospheric-Climate Links with Emphasis on the Upper Troposphere and Lower Stratosphere) project. The tested models range from the regional to the global scale, and include numerical weather prediction (NWP), chemical transport, and chemistry-climate models. Idealised tracers were used in order to prevent the model's chemistry schemes from influencing the results substantially, so that the effects of...

Abnormal context-reward associations in an immune-mediated neurodevelopmental mouse model with relevance to schizophrenia

Marie Anaïs Labouesse, Wolfgang Langhans & Urs Meyer
Impairments in central reward processing constitute an important aspect of the negative symptoms of schizophrenia. Despite itsclinical relevance, the etiology of deficient reward processing in schizophrenia remains largely unknown. Here, we used anepidemiologically informed mouse model of schizophrenia to explore the effects of prenatal immune activation on reward-relatedfunctions. The model is based on maternal administration of the viral mimic PolyI:C and has been developed in relation to theepidemiological evidence demonstrating enhanced risk of schizophrenia and...

Assessing the potential additionality of certification by the Round table on Responsible Soybeans and the Roundtable on Sustainable Palm Oil

Rachael Garrett, Kimberly M. Carlson, Ximena Rueda & Praveen Noojipady
Multi-stakeholder roundtables offering certification programs are promising voluntary governance mechanisms to address sustainability issues associated with international agricultural supply chains. Yet, little is known about whether roundtable certifications confer additionality, the benefits of certification beyond what would be expected from policies and practices currently in place. Here, we examine the potential additionality of the Round table on Responsible Soybeans (RTRS) and the Roundtable on Sustainable Palm Oil (RSPO) in mitigating conversion of native vegetation to...

A high-resolution image time series of the Gorner Glacier - Swiss Alps - derived from repeated unmanned aerial vehicle surveys

Lionel Benoit, Aurelie Gourdon, Raphael Vallat, Inigo Irarrazaval, Mathieu Gravey, Benjamin Lehmann, Gunther Prasicek, Dominik Gräff, Frédéric Herman & Gregoire Mariethoz
Modern drone technology provides an efficient means to monitor the response of alpine glaciers to climate warming. Here we present a new topographic dataset based on images collected during 10 UAV surveys of the Gorner Glacier glacial system (Switzerland) carried out approximately every 2 weeks throughout the summer of 2017. The final products, available at https://doi.org/10.5281/zenodo.2630456 (Benoit et al., 2018), consist of a series of 10 cm resolution orthoimages, digital elevation models of the glacier...

Interferometric Nanoparticle Detection

Sarah Kurmulis
Nanoparticles, particles with sizes between 1 and 100 nm are omnipresent in several fields ranging from high technology industries to health care and consumer goods. Biological nanoparticles include viruses, exosomes and proteins. In many applications such as health care, it is essential to detect the presence of certain nanoparticles. Moreover, it is often of high importance to measure their sizes and concentrations. Since these particles are smaller than the wavelength of light, their label-free detection...

U-Th and 10Be constraints on sediment recycling in proglacial settings, Lago Buenos Aires, Patagonia

Antoine Cogez, Frédéric Herman, Éric Pelt, Thierry Reuschlé, Gilles Morvan, Christopher M. Darvill, Kevin P. Norton, Marcus Christl, Lena Märki & François Chabaux
The estimation of sediment transfer times remains a challenge to our understanding of sediment budgets and the relationships between erosion and climate. Uranium (U) and thorium (Th) isotope disequilibria offer a means of more robustly constraining sediment transfer times. Here, we present new uranium and thorium disequilibrium data for a series of nested moraines around Lago Buenos Aires in Argentine Patagonia. The glacial chronology for the area is constrained using in situ cosmogenic 10Be analysis...

Non-invasive determination of murine placental and foetal functional parameters with multispectral optoacoustic tomography

Kausik Basak, Xosé Luís Deán-Ben, Sven Gottschalk, Michael Reiss & Daniel Razansky
Despite the importance of placental function in embryonic development, it remains poorly understood and challenging to characterize, primarily due to the lack of non-invasive imaging tools capable of monitoring placental and foetal oxygenation and perfusion parameters during pregnancy. We developed an optoacoustic tomography approach for real-time imaging through entire ~4 cm cross-sections of pregnant mice. Functional changes in both maternal and embryo regions were studied at different gestation days when subjected to an oxygen breathing...

Projections of Alpine snow-cover in a high-resolution climate simulation

Samuel Lüthi, Nikolina Ban, Sven Kotlarski, Christian Steger, Tobias Jonas & Christoph Schär
The recent development of high-resolution climate models offers a promising approach in improving the simulation of precipitation, clouds and temperature. However, higher grid spacing is also a promising feature to improve the simulation of snow cover. In particular, it provides a refined representation of topography and allows for an explicit simulation of convective precipitation processes. In this study we analyze the snow cover in a set of decade-long high-resolution climate simulation with horizontal grid spacing...

Corra: Computational framework and tools for LC-MS discovery and targeted mass spectrometry-based proteomics

Mi-Youn Brusniak, Bernd Bodenmiller, David Campbell, Kelly Cooke, James Eddes, Andrew Garbutt, Hollis Lau, Simon Letarte, Lukas N. Müller, Vagisha Sharma, Olga Vitek, Ning Zhang, Ruedi Aebersold & Julian D. Watts
Background Quantitative proteomics holds great promise for identifying proteins that are differentially abundant between populations representing different physiological or disease states. A range of computational tools is now available for both isotopically labeled and label-free liquid chromatography mass spectrometry (LC-MS) based quantitative proteomics. However, they are generally not comparable to each other in terms of functionality, user interfaces, information input/output, and do not readily facilitate appropriate statistical data analysis. These limitations, along with the array...
