Manuel Lussi, Timothy Sandy, Kathrin Doerfler, Norman Hack, Fabio Gramazio, Matthias Kohler & Jonas Buchli
In this paper we present a system for the in situ fabrication of a full-scale, load-bearing, and doubly-curved steel reinforced concrete wall. Two complementary vision-based sensing systems provide the feedback necessary to build a 12 meter long steel wire mesh as part of a novel digital building process. The sensing systems provide estimates of the robot pose, referenced to the CAD model of the building site, as well as feedback on the accuracy of the...

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...

Reactive Oxygen Species (ROS) Measurements in Laboratory and Ambient Studies

Jun Zhou
Breathing pristine clean air, a fundamental human right ever since the world was created, is threatened now and then on the road of human society development. To create the environment that supports our life in a sustainable way, we must solve the air pollution problem and at the same time continue our technologically based civilization. Although air pollution has attracted attention for centuries, the air-cleaning task is still arduous and needs long-term efforts to be...

A 19-isolate reference-quality global pangenome for the fungal wheat pathogen Zymoseptoria tritici

Thomas Badet, Ursula Oggenfuss, Leen Abraham, Bruce A. McDonald & Daniel Croll
Background The gene content of a species largely governs its ecological interactions and adaptive potential. A species is therefore defined by both core genes shared between all individuals and accessory genes segregating presence-absence variation. There is growing evidence that eukaryotes, similar to bacteria, show intra-specific variability in gene content. However, it remains largely unknown how functionally relevant such a pangenome structure is for eukaryotes and what mechanisms underlie the emergence of highly polymorphic genome structures....

Gampenrieder, Klaus Hergan, Wolfgang Gaissmaier, Dow-Mu Koh & Matthias Meissnitzer
Background The aim of the study is to investigate how well patients remember the radiologist’s name after a radiological examination, and whether giving the patient a business card improves the patient’s perception of the radiologist’s professionalism and esteem. Methods In this prospective and randomized two-centre study, a total of 141 patients with BI-RADS 1 and 2 scores were included. After screening examination comprising mammography and ultrasound by a radiologist, 71 patients received a business card...

A Teaching System for Hands-on Quadcopter Control

Paul Beuchat, Yvonne R. Stürz & John Lygeros
Quadcopters, popular in consumer and commercial applications, are a perfect testing ground for both basic and advanced control techniques. This makes them an ideal platform for offering experiment-based control courses. We present the software system developed to teach hands-on quadcopter control, that we have used to offer a short course to groups of 32 undergraduate electrical engineering students. Our system allows students to work simultaneously, each with a separate quadcopter. The software makes the hands-on...

Data for the Paper "Inflexible Social Inference in Individuals with Subclinical Persecutory Delusional Tendencies"

Katharina V. Wellstein
It has long been suspected that abnormalities in social inference (e.g., learning others’ intentions) play a key role in the formation of persecutory delusions (PD). In this study, we examined the association between subclinical PD and social inference, testing the prediction that proneness to PD is related to altered social inference and beliefs about others’ intentions. We included 151 participants who scored on opposite ends of Freeman’s Paranoia Checklist (PCL). The participants performed a probabilistic...

165Er: A new candidate for Auger electron therapy and its possible cyclotron production from natural holmium targets

Nadezda Gracheva, Tommaso S. Carzaniga, Roger Schibli, Saverio Braccini & Nicholas P. Van Der Meulen
165Er, a pure Auger-electron emitter, could be an attractive candidate for targeted radionuclide therapy. Auger electrons possess short penetration paths with high linear energy transfer. In this study, experimental cross-sections of the 165Ho(p, n)165Er nuclear reaction were measured and targets irradiated with protons using Injector II cyclotron at Paul Scherrer Institute (Switzerland) and the 18 MeV medical cyclotron laboratory at the University Hospital in Bern. A purification method was developed in order to obtain 165Er...

Myeloperoxidase and Septic Conditions Disrupt Sphingolipid Homeostasis in Murine Brain Capillaries In Vivo and Immortalized Human Brain Endothelial Cells In Vitro

Madeleine Goeritzer, Ioanna Plastira, Helga Reicher, Christina Leopold, Thomas O. Eichmann, Gerald Rechberger, Corina T. Madreiter-Sokolowski, Jürgen Prasch, Philipp Eller, Wolfgang F. Graier, Dagmar Kratky, Ernst Malle & Wolfgang Sattler
During inflammation, activated leukocytes release cytotoxic mediators that compromise blood–brain barrier (BBB) function. Under inflammatory conditions, myeloperoxidase (MPO) is critically involved in inflicting BBB damage. We used genetic and pharmacological approaches to investigate whether MPO induces aberrant lipid homeostasis at the BBB in a murine endotoxemia model. To corroborate findings in a human system we studied the impact of sera from sepsis and non-sepsis patients on brain endothelial cells (hCMEC/D3). In response to endotoxin, the...

Improving Syntactical Clone Detection Methods through the Use of an Intermediate Representation

Pedro M. Caldeira, Kazunori Sakamoto, Hironori Washizaki, Yoshiaki Fukazawa & Shimada Takahisa
Detection of type-3 and type-4 clones remains a difficult task. Current methods are complex, both on a conceptual and computational level. Similarly, their usage requires substantial implementation efforts. Instead of creating yet another method, it might be more productive to combine the simplicity of syntactic approaches with the abstractions granted by intermediate representations (IR). To this end, we devised a c-like IR based on LLVM and ran NiCad on it (LLNiCad). To establish whether the...

Uncovering a hidden diversity: optimized protocols for the extraction of dsDNA bacteriophages from soil

Pauline C. Göller, Jose M. Haro-Moreno, Francisco Rodriguez-Valera, Martin J. Loessner & Elena Gómez-Sanz
Background Bacteriophages (phages) are the most numerous biological entities on Earth and play a crucial role in shaping microbial communities. Investigating the bacteriophage community from soil will shed light not only on the yet largely unknown phage diversity, but may also result in novel insights towards their functioning in the global biogeochemical nutrient cycle and their significance in earthbound ecosystems. Unfortunately, information about soil viromes is rather scarce compared to aquatic environments, due to the...

Non-linear Control of Quad-copters via Approximate Dynamic Programming

Ángel Romero Aguilar
Approximate Dynamic Programming has proven to be successful in many discrete state applications such as playing the games of Tetris or chess. However, not so many applications involving continuous state space dynamics have been proposed. In this thesis we study the possibilities of applying these same techniques to the continuous, non-linear, high dimensional dynamics of a quad-rotor vehicle, by using the Linear Programming approach to find a set of polynomial approximations to the optimal value...

Colloidal Antimony Sulfide Nanoparticles as a High-Performance Anode Material for Li-ion and Na-ion Batteries

Kostiantyn V. Kravchyk, Maksym V. Kovalenko & Maryna I. Bodnarchuk
To maximize the anodic charge storage capacity of Li-ion and Na-ion batteries (LIBs and SIBs, respectively), the conversion–alloying-type Sb2S3 anode has attracted considerable interest because of its merits of a high theoretical capacity of 946 mAh g−1 and a suitable anodic lithiation/delithiation voltage window of 0.1–2 V vs. Li+/Li. Recent advances in nanostructuring of the Sb2S3 anode provide an effective way of mitigating the challenges of structure conversion and volume expansion upon lithiation/sodiation that severely...

Spatio-Temporal Modelling of a Biogenic Combined Heat and Power Plant Swarm for Switzerland

René Buffat
The Energy Strategy 2050 of the Swiss government aims to replace Swiss nuclear plants with renewable energy production by the year 2050. At present, the renewable energy sources with the highest remaining potential in Switzerland are expected to be photovoltaic (PV) and wind. Both energy sources are characterized by their intermittent energy production. In the last 10 years, PV has experienced significantly larger growth compared to wind. Thus, it is possible that PV will be...
