Detection of large acoustic energy flux in the solar atmosphere
, 2010 We study the energy flux carried by acoustic waves excited by convective motions at sub-photospheric levels. The analysis of high-resolution spectropolarimetric data taken with IMaX/Sunrise provides a total energy flux of ~ 6400--7700 Wm$^{-2}$ at a ...

The iterated structure of the all-order result for the two-loop sunrise integral [PDF]
, 2015 We present a method to compute the Laurent expansion of the two-loop sunrise integral with equal non-zero masses to arbitrary order in the dimensional regularisation e.

A Romantic Genius? The Experience of Knowledge that Shaped Werner Heisenberg's Scientific Persona
Berichte zur Wissenschaftsgeschichte, EarlyView.In 1976, the year that Werner Heisenberg passed away, Armin Hermann published a short biography, titled Werner Heisenberg in Selbstzeugnissen und Bilddokumenten. Since then, historians and biographers have offered their accounts on Heisenberg's life and his contributions to modern physics. Many of these biographies present Heisenberg as a genius.

The sunrise amplitude equation applied to an Egyptian temple [PDF]
arXiv, 2012 An equation, fundamental for solar energy applications, can be used to determine the sunrise amplitude at given latitude. It is therefore suitable for being applied to archaeoastronomical calculations concerning the orientation of towns, worship places and buildings.

Ecography, EarlyView.Prey species adjust their behavior along human‐use gradients by balancing risks from predators and humans. During hunting seasons, prey often exhibit strong antipredator responses to humans but may develop tolerance in suburban areas to exploit human‐mediated resources.

Differential Equations for the 2-Loop Equal Mass Sunrise [PDF]
Acta Phys.Polon. B34 (2003) 5311-5322, 2003 The differential equations for the 2-loop sunrise graph, at equal masses but arbitrary momentum transfer, are used for the analytic evaluation of the coefficients of its Laurent-expansion in the continuous dimension $d$.

Magneto-static Modeling from Sunrise/IMaX: Application to an Active Region Observed with Sunrise II [PDF]
, 2017 Magneto-static models may overcome some of the issues facing force-free magnetic field extrapolations. So far they have seen limited use and have faced problems when applied to quiet-Sun data. Here we present a first application to an active region.

eCherry: A Modelica Library for Modular Dynamic Modelling of Electrochemical Reactors
Electrochemical Science Advances, EarlyView.ABSTRACT Electrochemical reactors offer promising pathways for defossilizing the chemical industry. To understand the operation as well as to evaluate and optimise their performance and efficiency, modelling presents a crucial tool. Currently, no comprehensive open‐source library for dynamic modelling of electrochemical reactors exists, and instead ...

FROM Daystart Songflight: A Morning Journal [PDF]
, 2020 This piece, an excerpt from an ongoing manuscript of plein-air nature writing, is one of forty projected journal entries involving excursions beginning before sunrise, with exploration of natural settings and observations of natural phenomena (birds ...
