Destroying the circular economy in order to save it - three challenges for accurate investment decisions that have emerged in recent years

The circular economy concept, as presented by the Ellen MacArthur Foundation (EMF), together with many other organisations, could be threatened by opportunists and fantasists. In essence, anyone with an aversion to seek to scientifically clarify the presen ...

First implementation of transversely split proton beams in the CERN Proton Synchrotron for the fixed-target physics programme

Guido Sterbini, Cedric Jean-François Hernalsteens, Massimo Giovannozzi

A new extraction technique has been studied at the CERN Proton Synchrotron with a view of using it for the fixed-target physics programme at the Super Proton Synchrotron. The extraction scheme is based on advanced concepts of non-linear beam dynamics: prio ...

Time-dependent correlations in quantum magnets at finite temperature

Thomas Keller, Felix Groitl

In this Rapid Communication we investigate the time dependence of the gap mode of copper nitrate at various temperatures. We combine state-of-the-art theoretical calculations with high precision neutron resonance spin-echo measurements to understand the an ...

Similarity-Based Shape Priors for 2D Spline Snakes

Michaël Unser, Daniel Andreas Schmitter

We present a new formulation of a shape space containing all continuously defined 2D spline curves up to a similarity transform of a reference shape. We are able to measure a distance between an arbitrary curve and the shape space itself. Our contribution ...

The Eleventh And Twelfth Data Releases Of The Sloan Digital Sky Survey: Final Data From Sdss-Iii

Jean-Paul Richard Kneib, Zheng Zheng, Johan Comparat, David Schlegel, Timothée Guy Olivier Delubac, Jian Liu, Yuguang Chen, Yue Shen, Pierre Laurent

The third generation of the Sloan Digital Sky Survey (SDSS-III) took data from 2008 to 2014 using the original SDSS wide-field imager, the original and an upgraded multi-object fiber-fed optical spectrograph, a new near-infrared high-resolution spectrograp ...

Configuring Spatial Grids for Efficient Main Memory Joins

Anastasia Ailamaki, Thomas Heinis, Farhan Tauheed

The performance of spatial joins is becoming increasingly important in many applications, particularly in the scientific domain. Several approaches have been proposed for joining spatial datasets on disk and few in main memory. Recent results show that in ...

Power Electronic Traction Transformer-Low Voltage Prototype

Drazen Dujic, Akos Mester, Toufann Chaudhuri

Recently, a world’s first ever power electronic traction transformer (PETT) for 15 kV, 16 2 /3Hz railway grid, has been newly developed, commissioned, and installed on the locomotive, where it is presently in use. This marks an important milestone in the t ...

Time-domain performance of a patch-loaded band-reject UWB antenna

Anja Skrivervik, Nuno Miguel Faria Pires, Mohsen Koohestani

A previous study of a novel technique to design a band-reject UWB monopole antenna by using patch loading is extended. Frequency-domain measurements have confirmed that the antenna designed using this technique rejects the interfering signal at the two int ...

A synthetic review of feedbacks and drivers of shrub encroachment in arid grasslands

Paolo d'Odorico

Many arid grasslands around the world are affected by woody plant encroachment and by the replacement of a relatively continuous grass cover with shrub patches bordered by bare soil. This shift in plant community composition is often abrupt in space and ti ...

Permissiveness in Transactional Memories

Rachid Guerraoui, Vasu Singh

We introduce the notion of permissiveness in transactional memories (TM). Intuitively, a TM is permissive if it never aborts a transaction when it need not. More specifically, a TM is permissive with respect to a safety property
