Within a collaboration between MAX-lab and BESSY a one stage seeded HGHG-FEL has been set up at Maxlab. BESSY has built the undulator system consisting of a modulator, a radiator and an electromagnetic chicane. BESSY has also installed three types of diagnostic tools: optical fibres for a fast Cherenkov beam loss detection, optical fibres for absolute dose measurements via their radiation-induced
BACKGROUND: After over a decade of developments in field collection, laboratory methods and advances in high-throughput sequencing, contamination remains a key issue in ancient DNA research. Currently, human and microbial contaminant DNA still impose challenges on cost-effective sequencing and accurate interpretation of ancient DNA data.RESULTS: Here we investigate whether human contaminating DNA
Vegetation growth may adapt to climate warming by adjusting the relationship between photosynthetic capacity and temperature. However, changes in the optimal temperature for ecosystem productivity during recent decades of warming remain uncertain. Here we provide empirical evidence that global optimal temperature increased at a rate of 0.017 ± 0.002 °C y−1 from 1982 to 2016, using multiple dataset
The Particle Finite Element Method (PFEM) is attractive for the simulation of large deformation problems, e.g. in free-surface fluid flows, fluid–structure interaction and in solid mechanics for geotechnical engineering and production processes. During cutting, forming or melting of metal, quasi-incompressible material behaviour is often considered. To circumvent the associated volumetric locking
Accurate regulation of microfilament dynamics is central to cell growth, motility and response to environmental stimuli. Stabilizing and depolymerizing proteins control the steady-state levels of filamentous (F-) actin. Capping protein (CP) binds to free barbed ends, thereby arresting microfilament growth and restraining elongation to remaining free barbed ends. In all CPs characterized to date, a
We evaluate pseudo-real-time out-of-sample nowcasts for Swedish GDP employing factor models and mixed-data sampling regressions with single predictor variables. These two model classes can handle the data irregularities of a ragged-edge sample and differing sampling frequencies. The results show that pooling of the nowcasts outperforms a simple benchmark, even though only very few of the underlyin
The emergence of pandemics like Covid-19 has raised important issues regarding the safe utilisation of spaces due to the potential for virus transmission in both enclosed and open built environments. This chapter explores the challenges posed by pandemics in terms of safe space utilisation, considering the potential virus transmission risks. It presents a risk analysis methodology that makes use o
Multivariate random sums appear in many scientific fields, most notably in actuarial science, where they model both the number of claims and their sizes. Unfortunately, they pose severe inferential problems. For example, their density function is analytically intractable, in the general case, thus preventing likelihood inference. In this paper, we address the problem by the method of moments, unde
The question of the legal permissibility of heritable gene editing techniques is unsettled. The international consensus opposes clinical research and applications involving germline modifications. Building on previous work, this paper examines how international human rights law, particularly human right to science standards, can inform the regulation of this controversial advancement. We present t
Abstract: Diffusion-weighted imaging (DWI) offers critical insights into tissue microstructure through the assessment of water molecule random displacements and plays a central role in the assessment of neoplastic and non-neoplastic diseases. To successfully implement and use DWI in clinical practice, guidelines for acquisition, interpretation of image contrast and of artefacts should be followed,
Purpose: The Workplace Dialogue is a digitalized method directed at managers. The purpose of this study was to explore managers’ experiences of using the digital Workplace Dialogue in cases of employee ill-health. Design/methodology/approach: The Workplace Dialogue provides an easy and accessible method for managers, including text, short films, client examples and concrete guides that provides su
Indigenous archaeology and archaeology of Indigeneity are paramount in the contemporary world. We certainly need more of it across the archaeological scale and across the archaeological globe. Archaeology’s unhealthy attachment to colonialism, colonial administration and imperialism keeps on affecting our discipline on all levels. It is therefore encouraging to read Felix Acuto’s call for an engag
AIMS: Vascular atherosclerotic calcification is a pathological process marked by the abnormal deposition of calcium minerals in the intima. Asporin (ASPN) is a small leucine-rich proteoglycan which interacts with collagen and calcium. Due to its role in matrix mineralization, we hypothesized that ASPN might act as a regulator of vascular calcification, thereby promoting atherosclerotic plaque stab
The world has encountered numerous global crises, including epidemics, military conflicts, and economic collapse. Innovative digital technologies, such as Industry 4.0 (I4.0), can undoubtedly help improve industries’ operations during critical times. The dairy industry has seen an increment in technological adoption in the last few years. Adopting cutting-edge technologies is regarded as more feas
Abstract: Perfusion MRI techniques—including dynamic susceptibility contrast (DSC) MRI, dynamic contrast-enhanced (DCE) MRI, arterial spin labeling (ASL) MRI, and intravoxel incoherent motion (IVIM) MRI—hold strong potential as imaging techniques for diagnosing, staging, and monitoring disease across a range of clinical applications. However, clinical adoption, especially of quantitative parameter
