The climate impact of Arctic aerosols, like the Arctic Haze, and their origin are not fully understood. Therefore, long-term aerosol observations in the Arctic are performed. In this study, we present a homogenised data set from a sun and star photom

An Nd:YAG-based Raman lidar provides a mature technology to derive profiles of the optical properties of aerosols over a wide altitude range. However, the derivation of micro-physical parameters is an ill-posed problem. Hence, increasing the informat

Modeling a Spheroidal Particle Ensemble and Inversion by Generalized Runge–Kutta Regularizers from Limited Data

Autor: Stefanos Samaras, Christine Böckmann, Christoph Ritter

Publikováno v: AppliedMath, Vol 2, Iss 4, Pp 547-573 (2022)

Extracting information about the shape or size of non-spherical aerosol particles from limited optical radar data is a well-known inverse ill-posed problem. The purpose of the study is to figure out a robust and stable regularization method including

Publikováno v: Ritt, C, Grimm, R, Fernandéz, S, Alonso, J C & Grasser, K D 1998, ' Four Differently Chromatin-Associated Maize HMG Domain Proteins Modulate DNA Structure and Act as Architectural Elements in Nucleoprotein Complexes ', Plant Journal, vol. 14, pp. 623-631 .

In contrast to other eukaryotes which usually express two closely related HMG1-like proteins, plant cells have multiple relatively variable proteins of this type. A systematic analysis of the DNA-binding properties of four chromosomal HMG domain prot
