From thoughtless awareness to effortful cognition: alpha - theta cross-frequency dynamics in experienced meditators during meditation, rest and arithmetic

Julio Rodriguez-Larios, Pascal Faber, Peter Achermann, Shisei Tei & Kaat Alaerts
Neural activity is known to oscillate within discrete frequency bands and the synchronization between these rhythms is hypothesized to underlie information integration in the brain. Since strict synchronization is only possible for harmonic frequencies, a recent theory proposes that the interaction between different brain rhythms is facilitated by transient harmonic frequency arrangements. In this line, it has been recently shown that the transient occurrence of 2:1 harmonic cross-frequency relationships between alpha and theta rhythms (i.e....

Renewable energy investment risk: An investigation of changes over time and the underlying drivers

Florian Egli
Building an energy system compatible with the Paris Agreement requires large-scale investment in renewable energy technologies (RET). Designing effective energy policies, therefore, requires an understanding of the dynamics of RET investment risk. This study draws on RET project data and 40 interviews with investors in Germany, Italy and the United Kingdom. We identify the five most relevant RET investment risk types (curtailment, policy, price, resource and technology), show their relative importance over time and use...

A factorial cluster-randomised controlled trial combining home-environmental and early child development interventions to improve child health and development: rationale, trial design and baseline findings

Stella M. Hartinger, Nestor Nuño, Jan Hattendorf, Hector Verastegui, Walter Karlen, Mariela Ortiz & Daniel Mäusezahl
BACKGROUND Exposure to unhealthy environments and inadequate child stimulation are main risk factors that affect children's health and wellbeing in low- and middle-income countries. Interventions that simultaneously address several risk factors at the household level have great potential to reduce these negative effects. We present the design and baseline findings of a cluster-randomised controlled trial to evaluate the impact of an integrated home-environmental intervention package and an early child development programme to improve diarrhoea, acute...

Partial Acidulation of Rock Phosphate for Increased Productivity in Organic and Smallholder Farming

Harun Cicek, Gurbir S. Bhullar, Lokendra S. Mandloi, Christian Andres & Amritbir S. Riar
There is a need to investigate and identify locally available organic substrates with acidifying potential, which can be used as an additive in rock phosphate (RP)-organic material composting mixtures. This paper reviews attempts to increase P availability in the context of smallholder, low-input and organic farming, and presents a case study from Central India that used a participatory approach to address P deficiency issues in cotton-based organic systems. Study was conducted from 2010 to 2014...

Eye Gaze Tracking for Detecting Non-verbal Communication in Meeting Environments

Naina Dhingra, Christian Hirt, Manuel Angst & Andreas Kunz
Non-verbal communication in a team meeting is important to understand the essence of the conversation. Among other gestures, eye gaze shows the focus of interest on a common workspace and can also be used for an interpersonal synchronisation. If this non-verbal information is missing and or cannot be perceived by blind and visually impaired people (BVIP), they would lack important information to get fully immersed in the meeting and may feel alienated in the course...

Space Security: The Next Decade

Michael Haas
Private-sector initiatives have created considerable momentum in the space industry. The importance of space systems as critical infrastructures will continue to increase in the coming years. At the same time, it is increasingly likely that weapons will be deployed in space. For Switzerland, the trajectories of this trend bring economic opportunities, but also increased security risks.

Longitudinal Healthcare Analytics for Disease Management: Empirical Demonstration for Low Back Pain

Michael Müller-Peltzer, Stefan Feuerriegel, Werner Vach, Anne Molgaard Nielsen, Alice Kongsted & Dirk Neumann
Clinician guidelines recommend health management to tailor the form of care to the expected course of diseases. Hence, in order to decide upon a suitable treatment plan, health professionals benefit from decision support, i.e., predictions about how a disease is to evolve. In clinical practice, such a prediction model requires interpretability. Interpretability, however, is often precluded by complex dynamic models that would be capable of capturing the intrapersonal variability of disease trajectories. Therefore, we develop...

Global Dimming and Brightening Features during the First Decade of the 21st Century

Nikolaos Hatzianastassiou, Eleftherios Ioannidis, Marios-Bruno Korras-Carraca, Maria Gavrouzou, Christos D. Papadimas, Christos Matsoukas, Nikolaos Benas, Angeliki Fotiadi, Martin Wild & Ilias Vardavas
Downward surface solar radiation (SSR) trends for the first decade of the 2000s were computed using a radiative transfer model and satellite and reanalysis input data and were validated against measurements from the reference global station networks Global Energy Balance Archive (GEBA) and Baseline Surface Radiation Network (BSRN). Under all-sky conditions, in spite of a somewhat patchy structure of global dimming and brightening (GDB), an overall dimming was found that is weaker in the Northern...

Rapid expansion of Treg cells protects from collateral colitis following a viral trigger

Foxp3+ regulatory T (Treg) cells are essential for maintaining peripheral tolerance and preventing autoimmunity. While genetic factors may predispose for autoimmunity, additional environmental triggers, such as viral infections, are usually required to initiate the onset of disease. Here, we show that viral infection with LCMV results in type I IFN-dependent Treg cell loss that is rapidly compensated by the conversion and expansion of Vβ5+ conventional T cells into iTreg cells. Using Vβ5-deficient mice, we show...

This paper reports on a search for an extension to the scalar sector of the standard model, where a new CP-even (odd) boson decays to a Z boson and a lighter CP-odd (even) boson, and the latter further decays to a b quark pair. The Z boson is reconstructed via its decays to electron or muon pairs. The analysed data were recorded in proton-proton collisions at a center-of-mass energy s√ = 13 TeV, collected by...
