At synchrotron light storage rings there is demand for serving high-brilliance users requesting multibunch operation while simultaneously serving timing users who require single-bunch operation. One method to accomplish this is PPRE developed and currently in user operation at BESSY II. In the method, the transverse emittance of one of the bunches in the bunch train is increased by an incoherent b
This paper deals with limitations on control system performance due to load disturbances, measurement noise, actuator saturation and system dynamics. Simple problems which capture the essence of the problem are formulated and solved. The results make it possible to quickly explore a design problem for preliminary assessment before attempting to do massive computations. They are also useful ingredi
The structure tensor is a powerful tool describing the local intensity structure of an image or image sequence. In this paper we give a model for the noise distribution of the components of the tensor. In order to do so we have also investigated some properties of the gamma distribution. We show that, given an input image corrupted with Gaussian noise, the noise in the structure tensor can be mode
The anations of Pt(H2O)42+ and PtX(H2O)3+ (to trans-PtX(H2O)2) by X− = Cl−, Br−, I− and SCN− and the anation of trans-PtX2(H2O)2) by X− = Cl−, Br− and I− have been studied at 25 °C and 1.00 M perchlorate medium using both stopped-flow and conventional spectrophotometry. For large excess of X−, PtX42− is formed according to the mechanism in Figure 1. The results indicate an entering ligand order of
POPULAR SCIENTIFIC SUMMARYI was on my way home, sitting on the bus. My tired eyes swept through the pages of the local newspaper and that was the moment I met Lisa. She had previously been diagnosed with cancer. She had recovered and was back to her daily life. Unfortunately the cancer has come back and it has spread to several organs. Lisa as a mother of two kids, as a wife, as a daughter, as a sTelomeres are special DNA-protein structures that protect ends of chromosomes from being recognized as double-strand breaks. Telomeres consist of tandemly repeated units of TG-rich DNA and associate with telomere-specific proteins.When a cell replicates its chromosomes, a certain piece of DNA is lost from chromosomal ends due to the ´´ end replication problem´´. This progressive shortening of telo
We propose a description of nonequilibrium systems via a simple protocol that combines exchange-correlation potentials from density functional theory with self-energies of many-body perturbation theory.The approach, aimed to avoid double counting of interactions, is tested against exact results in Hubbard-type systems, with respect to interaction strength, perturbation speed and inhomogeneity, andWe propose a description of nonequilibrium systems via a simple protocol that combines exchange-correlation potentials from density functional theory with self-energies of many-body perturbation theory.

The thesis sets out to investigate the research question “Does subject certification affect student achievement in mathematics?” By using data from an international large-scale assessment of student skills, Trends in International Mathematics and Science Study (TIMSS), the thesis uses student achievement scores in mathematics as the dependent variable in a series of multiple linear regression mode
This study examines price elasticity of demand for train travel along the Southern Main Line in Sweden, focusing on four specific routes: Malmö-Stockholm, Lund-Stockholm, Malmö-Linköping, and Linköping-Stockholm. Using sales data provided by Snälltåget for a period of 28 days in 2024, the research analyzes how ticket prices influence passenger numbers, applying econometric models such as log-log r
In light of the current situation in the EU, after the COVID-19 pandemic and the ongoing war in Ukraine, Europe is undoubtedly facing a critical situation. This thesis conducts an exploratory analysis of ontological (in)security in Czechia and Slovakia to investigate a region where very few academics have analyzed it from an ontological security perspective. By using a mixed method multiple case s
This paper presents a novel enterprise architecture concept for mapping businesscapabilities called the Milky Way. It aims to create an anchoring image that can be used to communicate with various stakeholders. We look at examples from research data management and student administration. All the presented projects, from different universities, were highly successful in achieving stakeholder buy-in
This essay takes a starting point in the well-known tension between the media logic and the scientific logic and the challenges when communicating science in a mediatized society. Building on the experience of engaging in research comics, both as a method for communicating science and a creative example of a meeting between science and art, we introduce a framework — a pedagogical tool — for how sThis essay takes a starting point in the well-known tension between the media logic and the scientific logic and the challenges when communicating science in a mediatized society.

Title: Learning and creating – A study of organists’ learning and creative processes in playing a hymn and a hymn prelude. In this study, I wanted to explore how organists experience the learning and creative processes in interpretation of written music and improvisation. The empirical study consisted of four organists playing a hymn prelude and a hymn, and the initial aim was to study individual
Purpose: The purpose is to improve the understanding of the process of applying blockchain technology in the financial services industry through information published by the most representative companies and institutions in the global landscape. Methodology: Qualitative research has been conducted through secondary data, which has been analyzed by employing thematic analysis. Theoretical perspec
This paper deals with the disputable issue of the existence of Malthus’ Preventive Check in Chinese population. With the help of a newly established historical database (Demographic Database of Colonial Taiwan, DDCT), which currently including the individual level data regarding to the socio-demographic backgrounds of the registered population in fifteen townships in North and Western Taiwan, we t
