Linear representations of hyperelliptic mapping class groups

open access: yes, 2020
Let $p:S\to S_g$ be a finite $G$-covering of a closed surface of genus $g\geq 1$ and let $B$ its branch locus. To this data, it is associated a representation of a finite index subgroup of the mapping class group $\operatorname{Mod}(S_g\smallsetminus B)$

Stochastic optimization and worst-case analysis in monetary policy design [PDF]

open access: yes, 2005
In this paper, we examine the cost of insurance against model uncertainty for the Euro area considering four alternative reference models, all of which are used for policy-analysis at the ECB.We find that maximal insurance across this model range in ...

Electron Pre-Acceleration at Nonrelativistic High-Mach-Number Perpendicular Shocks [PDF]

open access: yes, 2017
We perform particle-in-cell simulations of perpendicular nonrelativistic collisionless shocks to study electron heating and pre-acceleration for parameters that permit extrapolation to the conditions at young supernova remnants. Our high-resolution large-

Fritz Scheffer Under National Socialism: Assessing His Political Involvement

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Aims This article examines the role of soil scientist Fritz Scheffer (1899–1979) under National Socialism and offers a critical assessment of his scientific, institutional, and political positioning between 1933 and 1945. It asks how Scheffer shaped his career within the tension between disciplinary specialization, political expectations, and ...

The Enlightenment And The Dilemmas Of The Schwärmerei

open access: yesAufklärung, 2014
In this article we intend to show some precedents of the discussion on the meaning of the Enlightenment (1783-1784) from some linguistic controverses around the phenomena entusiasta. So comes the need to distinguish between “Enhusiasmus” and “Schwärmerei”

Field Studies on the Influence of High‐Voltage Direct Transmission Underground Cables on Soils Along the SuedLink Route in Southwest Germany

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
During regular operation of the SuedLink at a load ≤75 %, the average increase in temperature in the plowing horizon is expected to be less than 1.6°C in the soils along the route in Southwest Germany. ABSTRACT Background The SuedLink was planned as a high‐voltage direct‐current underground cable route. The construction itself is a massive intervention

The Illusion of Structural Order: Evaluating the Suppression of Amorphous Carbon Black Pigment Bands in SSE‐Processed Handheld Raman Spectra

open access: yesJournal of Raman Spectroscopy, EarlyView.
The handheld Raman with SSE system efficiently mitigates fluorescence; however, it may also bias the Raman response towards graphitic domains in carbon‐based black pigments, thereby concealing amorphous carbon contributions that are critical for pigment type identification.

Sich-Erinnern als (Über-)Leben oder Wie sich Biografien in Literatur verwandelten. Zu den ‚Initiationsromanen‘ von Armin Müller, Günter Grass und Wieland Förster

open access: yesColloquia Germanica Stetinensia, 2019
Armin Müller’s “Der Puppenkönig und ich” (1986), Günter Grass’ “Beim Häuten der Zwiebel” (2006) and Wieland Förster’s “Tamaschito” (2017) are more than just initiation stories – or should one restictively speak of autobiographical records?
