Vad händer med Ryssland efter Putin?

Putin lever inte för evigt, men dagens Ryssland är uppbyggt kring Putin som ledaren. Sovjettidens så kallade ”kremlologi” – att omvärlden spekulerar och ibland försöker tyda tecken som inte finns – kan märkas även i dag. Det är väldigt svårt att föreställa sig Ryssland om fem år, både för ryssar och för andra, skriver Mi Lennhag, Östeuropaexpert vid Lunds universitet och Vilhelm Konnander, säkerhe

The Routledge Companion to Media and Tourism

The Routledge Companion to Media and Tourism provides a comprehensive overview of the research into the convergence of media and tourism and specifically investigates the concept of mediatized tourism.This companion offers a holistic look at the relationship between media and tourism by drawing from a global range of contributions by scholars from disciplines across the humanities and social scien

First direct seeding at 38 nm

The sFLASH project at DESY is an experiment to study direct seeding using a source based on the high-harmonic generation (HHG) process. In contrast to SASE, a seeded FEL exhibits greatly improved longitudinal coherence and higher shot-to-shot stability (both spectral and energetic). In addition, the output of the seeded FEL is intrinsically synchronized to the HHG drive laser, thus enabling pump-p

Characterization of seeded FEL pulses at flash : Status, challenges and opportunities

Since 2004 the free-electron laser FLASH at DESY has been operated in the Self-Amplified Stimulated Emission mode (SASE), delivering gigawatt pulses with wavelengths between 6.5 nm and 40 nm in the femtosecond domain. In 2009 DESY installed an additional radiofrequency module for controlling the phase space of the electron bunches that gives the possibility to generate bunches with high peak curre

Coherent harmonic generation using the elettra storage-ring optical klystron : A numerical analysis

Coherent harmonic generation can be obtained by means of frequency up-conversion of a high-power external laser focused into the first undulator of an optical klystron. The standard configuration is based on a single-pass device, where the seed laser is synchronized with an electron beam entering the first undulator of the optical klystron after being accelerated using a linear accelerator. As an

Mätning och motstånd : Sifferstyrning i socialtjänstens vardag

In the name of transparency and accountability, numbers and statistics have gained importance as indicators of quality, effectiveness and efficiency of welfare services such as social work. It has been argued that the requirements to formalise how and on what grounds decisions are made have undermined the professional autonomy and discretion of social workers. These requests have arguably also led

Operation of the european FEL at Elettra below 190 nm : A tunable laser source for VUV spectroscopy

Thanks to an intensive technological effort in the framework of the EUFELE collaboration, the European FEL at ELETTRA was able to break the previous record for the shortest wavelength of an FEL oscillator. Novel solutions were adopted for multilayer mirrors to allow FEL operation in the wavelength region between 160 and 190 nm, which is one of the main targets of the project. The characteristics o

Extracellular matrix hydrogel derived from decellularized tissues enables endodermal organoid culture

Organoids have extensive therapeutic potential and are increasingly opening up new avenues within regenerative medicine. However, their clinical application is greatly limited by the lack of effective GMP-compliant systems for organoid expansion in culture. Here, we envisage that the use of extracellular matrix (ECM) hydrogels derived from decellularized tissues (DT) can provide an environment cap

Full Judicial Review or Administrative Discretion? A Swedish Perspective on Deference to the Administration

Swedish administrative law has not devoted much attention to the con-cepts of discretion or deference with respect to the administration. This is explained by the historically founded competence of administrative courts conducting a full review under the so-called administrative-judicial form of appeal. Here, the administrative court has the same decision-making competence as the deciding administ

Deep sequencing of myxoinflammatory fibroblastic sarcoma

Myxoinflammatory fibroblastic sarcoma (MIFS) has recurrent genetic features in the form of a translocation t(1;10)(p22-31;q24-25), BRAF gene fusions, and/or an amplicon in 3p11-12 including the VGLL3 gene. The breakpoints on chromosomes 1 and 10 in the t(1;10) cluster in or near the TGFBR3 and OGA genes, respectively. We here used a combination of deep sequencing of the genome (WGS), captured sequ

Genomic and transcriptomic features of dermatofibrosarcoma protuberans : Unusual chromosomal origin of the COL1A1-PDGFB fusion gene and synergistic effects of amplified regions in tumor development

The dermatofibrosarcoma protuberans family of tumors (DPFT) comprises cutaneous soft tissue neoplasms associated with aberrant PDGFBR signaling, typically through a COL1A1-PDGFB fusion. The aim of the present study was to obtain a better understanding of the chromosomal origin of this fusion and to assess the spectrum of secondary mutations at the chromosome and nucleotide levels. We thus investig

Collective decision-making appears more egalitarian in populations where group fission costs are higher

Collective decision-making is predicted to be more egalitarian in conditions where the costs of group fission are higher. Here, we ask whether Trinidadian guppies (Poecilia reticulata) living in high or low predation environments, and thereby facing differential group fission costs, make collective decisions in line with this prediction. Using a classic decision-making scenario, we found that fish

Spacetime colour reconnection in Herwig 7

We present a model for generating spacetime coordinates in the Monte Carlo event generator Herwig 7, and perform colour reconnection by minimizing a boost-invariant distance measure of the system. We compare the model to a series of soft physics observables. We find reasonable agreement with the data, suggesting that pp-collider colour reconnection may be able to be applied in larger systems.
