Glacier mass loss is recognized as a major contributor to current sea level rise. However, large uncertainties remain in projections of glacier mass loss on global and regional scales. We present an ensemble of 288 glacier mass and area change projections for the 21st century based on 11 glacier models using up to 10 general circulation models and four Representative Concentration Pathways...

Recent findings of new Higgs modes in unconventional superconductors require a classification and characterization of the modes allowed by nontrivial gap symmetry. Here we develop a theory for a tailored nonequilibrium quantum quench to excite all possible oscillation symmetries of a superconducting condensate. We show that both a finite momentum transfer and quench symmetry allow for an...

Leaving peace for war : An exploratory study of Swiss men’s trajectories toward engagement in Arab conflicts

Ajil, Ahmed

In: sozialpolitik.ch, 2019, vol. 2, no. 3, p. Article: 2.3

While the issue of foreign fighting has been very present in Swiss public discourse in recent years, little is known about the actual trajectories of young men who engage in this particular form of political violence. Based primarily on face-to-face in-depth interviews with four Swiss male nationals who travelled to conflict zones in the Arab World, the present analysis offers insights into the...
