Heterogeneous economic growth vulnerability across Euro Area countries under stressed scenarios
We analyse economic growth vulnerability of the four largest Euro Area (EA) countries under stressed macroeconomic and financial conditions. Vulnerability, measured as a lower quantile of the growth distribution conditional on EA-wide and country-specific underlying factors, is found to be higher in Germany, which is more exposed to EA-wide economic conditions, and in Spain, which has large country-specific sectoral dynamics. We show that, under stress, financial factors amplify adverse macroec…

Russian attacks show with clarity that Putin is mocking Trump, Poland's Sikorski says
Arriving for talks in Rome, Polish foreign minister Radosław Sikorski said the continued Russian attacks show that
“Vladimir Putin of Russia is mocking the peace efforts of president Donald Trump.”
He also stressed that Europe is stepping up its plans for defence, with increased spending.
Talking about the meeting ahead, he said leaders needed to
“strategise about what to do…

Higher-Order Transverse Discontinuity Mapping in Filippov Systems: Analysis and Experimental Validation using an Electronic Circuit
This paper shows that linearizing the transverse discontinuity mapping (TDM) in Filippov systems can produce inaccurate predictions of the dynamics in impact oscillators operating near a pre-stressed soft barrier. This discrepancy arises from the limitations of the linearized saltation matrix, which inaccurately predicts impacts in the local neighborhood of the discontinuity boundary. To address this issue, a higher-order approximation of the TDM is derived, which accurately captures the onset …

Friends in #HigherEd, it’s the season for finals (on the semester system). Be kind. Your students are anxious. You are absorbing their anxiety. You are also stressed by grading & all the projects you thought you had time to do before now. For you and them, have water, healthy snacks, encourage rest.

Modeling and computation of the effective elastic behavior of parallelogram origami metamaterials
Origami metamaterials made of repeating unit cells of parallelogram panels joined at folds dramatically change their shape through a collective motion of their cells. Here we develop an effective elastic model and numerical method to study the large deformation response of these metamaterials under a broad class of loads. The model builds on an effective plate theory derived in our prior work [64]. The theory captures the overall shape change of all slightly stressed parallelogram origami defor…
