Dynamic Factor Trees and Forests – A Theory-led Machine Learning Framework for Non-Linear and State-Dependent Short-Term U.S. GDP Growth Predictions
(2020)Machine Learning models are often considered to be “black boxes” that provide only little room for the incorporation of theory (cf. e.g. Mukherjee, 2017; Veltri, 2017). This article proposes so-called Dynamic Factor Trees (DFT) and Dynamic Factor Forests (DFF) for macroeconomic forecasting, which synthesize the recent machine learning, dynamic factor model and business cycle literature within a unified statistical machine learning framework ...Working Paper -

Sicherheitspolitische Trends 2020-2028: Intensivierte Grossmächtekonkurrenz
(2020)CSS Policy BriefsEvery year, the CSS analyzes developments in world politics and their potential consequences for Switzerland over the next eight years. This year, we focus on the intensifying great power competition between the United States, China and Russia, as well as Artificial Intelligence as a key technology and a strategic resource.Report -
Glaciers
(2020)Meltwater from Alpine glaciers is a key component of the Swiss hydrological budget: It significantly contributes to total discharge, sustains minimum flow levels during dry periods, and shapes seasonal regimes. Due to climate change, Swiss glaciers are anticipated to lose between 59% and 93% of their 2018 ice volume by 2100. The associated glacier retreat will impact hydrology, ecosystems, sediment transport, water quality, landscapes, ...Report -
Determinanten des Risikomanagements in der Schweizer Landwirtschaft am Beispiel von D. suzukii
(2020)Das Ziel dieses Projekts war zu analysieren, (a) welche Risiken und Mehrkosten Schweizer Steinobst- (Kirschen und Zwetschgen), Beeren- und TraubenproduzentInnen durch die Drosophila suzukii (D. suzukii) wahr-nehmen, (b) welche Massnahmen ProduzentInnen nutzen, um einen Befall zu bekämpfen oder mit-tels präventiver Strategien zu vermeiden, (c) was die beobachtete Heterogenität in den gewählten Strategien erklärt, und (d) welche ...Report -

Annex to Deliverable Technical Report D1.2.2
(2020)This Annex report documents the first workshop series on the Weather Research Forecasting model (WRF) held by experts of the Cooling Singapore 1.5 project. The objective of the workshop series was to address technical questions for the next thematic areas: 1. General aspects of WRF, 2. Approach to Anthropogenic Heat modelling in WRF, and 3. Approach to Local Climate Zones modelling in WRF. The Workshop consisted of rounds of Q&A ...Report -

Observation of Magnetic Proximity Effect Using Resonant Optical Spectroscopy of an Electrically Tunable MoSe2/CrBr3 Heterostructure
(2020)arXivVan der Waals heterostructures combining two-dimensional magnetic and semiconducting layers constitute a promising platform for interfacing magnetism, electronics, and optics. Here, we use resonant optical reflection spectroscopy to the observe magnetic proximity effect in a gate-tunable MoSe2/CrBr3 heterostructure. High quality of the interface leads to a giant zero-field splitting of the K and K' valley excitons in MoSe2, equivalent to ...Working Paper -
Comment on: Is the Hydrated Electron Vertical Detachment Genuinely Bimodal? J. Phys. Chem. Lett. 2019, 10, 4910-4913
(2020)In a recent article, David Bartels addresses the issue of the band shape of the genuine binding energy spectrum of the hydrated electron. He essentially claims that the genuine binding energy of the hydrated electron must be Gaussian in shape independent of the photon energy used for ionization, contrary to what was found in our previous work for excitations energies in the UV (3.6-5.8 eV photon energy). Further, he alleges that the ...Working Paper -
Can current experimental data exclude non-Gaussian genuine band shapes in ultraviolet photoelectron spectra of the hydrated electron?
(2020)Two recent articles present results that allegedly exclude a possible multimodal distribution of the hydrated electron in ultraviolet photoelectron spectra. The first article bases its conclusion on the assumption that the non-Gaussian genuine band shape previously retrieved for the solvated electron in liquid water is an artefact arising from insufficient electron scattering cross sections used in the retrieval. The second article excludes ...Working Paper -

Warum gibt es keine namhafte Schweizer IT-Industrie?
(2020)In den 1950er Jahren hatte die ETH Zürich einen gemieteten mechanischen Relaisrechner (Zuse Z4) und einen selbst gebauten elektronischen Röhrenrechner (Ermeth). Zudem veröffentlichte sie eine wegweisende Schrift zum Computerbau, eine Habilitationsschrift zur automatischen Programmierung und war massgeblich an der Entwicklung der Programmiersprache Algol beteiligt. Trotzdem gelang es damals (und auch später) nicht, eine namhafte Schweizer ...Working Paper -
SPACERGY
(2019)SPACERGY builds upon the need for planning authorities to develop new models to implement energy transition strategies in the urban environment, departing from the exploitation or reciprocity between space and energy systems. Several policies have been made by each EU nation, but effective and practical tools to guide the urban transformations towards a carbon-neutral future present several challenges. The first challenge is to confront ...Report -
immuneSIM: tunable multi-feature simulation of B- and T-cell receptor repertoires for immunoinformatics benchmarking
(2019)bioRxivB- and T-cell receptor repertoires of the adaptive immune system have become a key target for diagnostics and therapeutics research. Consequently, there is a rapidly growing number of bioinformatics tools for immune repertoire analysis. Benchmarking of such tools is crucial for ensuring reproducible and generalizable computational analyses. Currently, however, it remains challenging to create standardized ground truth immune receptor ...Working Paper -
Discrete populations of isotype-switched memory B lymphocytes are maintained in murine spleen and bone marrow
(2019)bioRxivHere we describe tissue-resident memory B lymphocytes of spleen and bone marrow. Single cell transcriptomes and B cell receptor repertoires identify several exclusive populations of isotype-switched memory B cells (Bsm) in murine spleen and bone marrow, and one interconnected population of 10-20%. A population of marginal zone-like Bsm is located exclusively in the spleen while a novel population of quiescent Bsm is located exclusively ...Working Paper
