Possible chirality in the doubly-odd Tl-198 nucleus: Residual interaction at play
- 2008
-
In: Physical Review C (Nuclear Physics). - 0556-2813. ; 78:2
-
Journal article (peer-reviewed)abstract
- A candidate for chiral bands was found in Tl-198 for the first time in a mass region of oblate (or nonaxial with gamma >= 30 degrees) deformed nuclei. Two bands show very similar quasiparticle alignments, moments of inertia, and B(M1)/B(E2) ratios. They have a relative excitation energy of about 500 keV and different patterns of energy staggering. Calculations using the two-quasiparticle-plus-triaxial-rotor model with residual proton-neutron interaction included show that a triaxial deformation with gamma similar to 44 degrees agrees very well with all the experimental observations. Furthennore, considerable energy staggering for both partner bands was calculated for this pi h(9/2) circle times vi(13/2)(-1) configuration at gamma - 30 degrees, suggesting that chiral bands may have substantial energy staggering.

Campaigning Against Europe? : The Role of Euroskeptic Fringe and Mainstream Parties in the 2009 European Parliament Election
- 2013
-
In: Journal of Political Marketing. - : Routledge. - 1537-7857 .- 1537-7865. ; 12:1, s. 77-99
-
Journal article (peer-reviewed)abstract
- In this article, we analyze political parties' campaign communication during the 2009 European Parliamentary election in 11 countries (Austria, Bulgaria, Czech Republic, Germany, Hungary, The Netherlands, Poland, Portugal, Spain, Sweden, and the UK). We study which types of issues Euroskeptic fringe and Euroskeptic mainstream parties put on their campaign agendas and the kind and extent of EU opposition they voice. Further, we seek to understand whether Euroskeptic and non-Euroskeptic parties co-orient themselves toward each other within their national party systems with regard to their campaigns. To understand the role of Euroskeptic parties in the 2009 European Parliamentary elections, we draw on a systematic content analysis of parties' posters and televised campaign spots. Our results show that it is Euroskeptic parties at the edges of the political spectrum who discuss polity questions of EU integration and who most openly criticize the union. Principled opposition against the project of EU integration, however, can only be observed in the UK. Finally, we find indicators for co-orientation effects regarding the tone of EU mobilization: In national political environments where Euroskeptic parties strongly criticize the EU, pro-European parties at the same time publicly advance pro-EU positions.

Development of Curative Therapies for Ewing Sarcomas by Interdisciplinary Cooperative Groups in Europe.
- 2015
-
In: Klinische Pädiatrie. - : Georg Thieme Verlag KG. - 1439-3824 .- 0300-8630. ; 227:3, s. 108-115
-
Research review (peer-reviewed)abstract
- Curative therapies for Ewing sarcoma have been developed within cooperative groups. Consecutive clinical trials have systematically assessed the impact and timing of local therapy and the activity of cytotoxic drugs and their combinations. They have led to an increase of long-term disease-free survival to around 70% in patients with localized disease. Translational research in ES remains an area in which interdisciplinary and international cooperation is essential for future progress. This article reviews current state-of-the art therapy, with a focus on trials performed in Europe, and summarizes novel strategies to further advance both the cure rates and quality of survival.

Survival following disease recurrence of primary localized alveolar rhabdomyosarcoma
- 2013
-
In: Pediatric Blood & Cancer. - : Wiley. - 1545-5009 .- 1545-5017. ; 60:8, s. 1267-1273
-
Journal article (peer-reviewed)abstract
- Background Recurrences in primary localized alveolar rhabdomyosarcoma (RMA) are common. Post-relapse survival is poor. We evaluated prognostic factors including relapse treatment in patients with recurrent RMA. Methods Relapses occurred in 115/235 patients with nonmetastatic RMA treated in four consecutive CWS-trials after achievement of a complete remission. Sufficient information about post-relapse treatment and outcome could be obtained in 99 patients and was retrospectively analyzed. Results Nine of 99 patients received no salvage therapy and died after a median of 2 months. The remaining 90 patients received multimodal relapse treatment including mandatory chemotherapy. Recurrences were grossly resected in 39 patients; 57 patients received radiation. At a median follow-up from relapse of 8 years, 20 patients were alive and disease-free (5-year post-relapse survival [PROS] 21.3 +/- 8). All surviving patients apart from a single individual had an isolated, circumscribed recurrence. Sixteen of 20 survivors were treated with adequate local relapse therapy (ALRT, i.e., either complete resection or gross resection+radiation). Survival in the subgroup of 27 individuals with circumscribed recurrences and ALRT was significantly better (PROS 53.7 +/- 19) compared with disseminated recurrences and/or tumors treated without ALRT. Absence of primary lymph node involvement, circumscribed relapses, ALRT, and achievement of a second CR were identified as independent favorable risk factors. Conclusion Post-relapse survival for primary localized RMA is generally poor. However, certain patient groups differed significantly in their likelihood of survival and 50% of patients with circumscribed relapses treated with ALRT survived. These findings may form the basis for an evidence-based risk-stratification for recurrent disease including relapse treatment.

Chemical composition and morphology of individual aerosol particles from a CARIBIC flight at 10 km altitude between 50 degrees N and 30 degrees S
- 2008

In: Journal of Geophysical Research. - 2156-2202. ; 113:D23

Journal article (peer-reviewed)abstract
- Analysis of individual particles by analytical electron microscopy as well as quantitative analysis using particle-induced X-ray emission (PIXE) and particle elastic scattering analysis (PESA) were carried out on samples collected from a flight at 10 km altitude between 50 degrees N and 30 degrees S as part of the Civil Aircraft for Regular Investigation of the atmosphere Based on an Instrument Container (CARIBIC) project (http://www.caribic-atmospheric.com). Particle morphology showed large variability with sampling latitude. Complicated branched structures dominated the large particles of the extratropical northern and southern hemisphere and the northern tropics. Particles in the tropics of the southern hemisphere were small in size and large in number concentration, whereas particles in or close to the intertropical convergence zone were few and small in size. Particles in the lowermost stratosphere were found to have similar structures but more branched than the ones found in the upper troposphere of the extratropics. Quantitative analysis revealed that the sulfur concentration varied by a factor of 50 in the nine samples analyzed in this study. The carbon-to-sulfur mass concentration ratio was lowest in the lowermost stratosphere (0.5) and highest in the tropics of the southern hemisphere (3.5). The elemental distribution of carbon and sulfur in individual particles was mapped by energy-filtered transmission electron microscopy (EFTEM). Almost all particles analyzed contained a mixture of carbonaceous and sulfurous matter. Particles with satellites were found by EFTEM to contain both carbon and sulfur in the central particle, whereas in the satellite particles only carbonaceous material was detected.
