However, whether there is synchronisation of these strategies at the entire community level is unclear. Here, we combine trait data for 2800 above- and belowground taxa from 14 trophic guilds spanning a disturbance and resource availability gradient in German grasslands. The results indicate that most guilds consistently respond to these drivers through both direct and trophically mediated effects, resulting in a 'slow-fast' axis at the level of the entire community. Using 15 indicators of carbon and nutrient fluxes, biomass production and decomposition, we also show that fast trait communities are associated with faster rates of ecosystem functioning. These findings demonstrate that 'slow' and 'fast' strategies can be manifested at the level of whole communities, opening new avenues of ecosystem-level functional classification.}, language = {en} } @misc{FischerHaeuslerRogassetal., author = {Fischer, Ulrich and H{\"a}usler, Tobias and Rogaß, Harald and Rottmann, M. and Kraft, A. and Heckner, K.-H.}, title = {Heat Transport and Thermal Expansion of Electrochromic Glazing Systems due to Solar Irradiation}, series = {International Journal of Thermophysics}, volume = {25}, journal = {International Journal of Thermophysics}, number = {4}, issn = {1572-9567}, pages = {1299 -- 1307}, language = {en} } @inproceedings{HaeuslerFischerRottmannetal., author = {H{\"a}usler, Tobias and Fischer, Ulrich and Rottmann, M. and Kraft, A. and Heckner, K.-H.}, title = {Solar Optical Properties and Daylight Potential of Electrochromic Windows}, series = {World Renewable Energy Congress VIII, book of abstracts, Denver, Colorado USA USA, August 29 - September 3, 2004}, booktitle = {World Renewable Energy Congress VIII, book of abstracts, Denver, Colorado USA USA, August 29 - September 3, 2004}, publisher = {National Renewable Energy Laboratory}, address = {Golden}, pages = {S. 195}, language = {en} } @misc{WeissMeissnerGuillardeauetal., author = {Weiß, Sabine and Meissner, Andreas and Guillardeau, A. and Dudzinski, Wlodzimierz and Fischer, Annette}, title = {Characterisation of microstructure and microtexture of coronary artery stents after fatigue deformation}, series = {Fatigue 2006, Proceedings 9th International Fatigue Congress May 14-19, 2006 Atlanta}, journal = {Fatigue 2006, Proceedings 9th International Fatigue Congress May 14-19, 2006 Atlanta}, publisher = {Georgia Institute of Technology}, address = {Atlanta, Ga.}, language = {en} } @misc{FischerBurgaudAmeretal., author = {Fischer, Annette and Burgaud, D. and Amer, A.

Up to now, Ag-terminated Si(111) has been employed as the model substrate for the growth of 3,4,9,10-perylene tetracarboxylic dianhydride (PTCDA) on semiconductors. In this study, we will show that Bi termination results in PTCDA films of superior epitaxial quality. We have studied the growth of PTCDA on bismuth-passivated Si(111) in detail by means of spot profile analysis of low-energy electron diffraction (SPA-LEED), X-ray photoemission spectroscopy (XPS), near-edge X-ray absorptionfine structure (NEXAFS), and scanning tunneling microscopy (STM). The XPS results reveal the presence of intact PTCDA molecules on the surface upon adsorption. NEXAFS data indicate the PTCDA molecules being oriented with their molecular plane parallel to the surface. STM shows a very smooth growth front of the PTCDA film, preserving the step structure of the substrate. High-resolution SPA-LEED data demonstrate the presence of a multidomain surface with a rich variety of PTCDA surface structures, which were identified to be most prominently herring-bone polytypes. However, in the monolayer range, quadratic brick-wall structures and a nearly square-like structure as well as a perylene-like structure have also been found. Despite the simultaneous presence of multiple domains, the individual domains show excellent lateral ordering, with larger domain sizes as compared to the case of Ag-terminated Si(111).}, language = {en} } @misc{FischerWoodsBilz, author = {Fischer, Saskia M. and Woods, Heather A. and Bilz, Ludwig}, title = {Class teachers' bullying-related self-efficacy and their students' bullying victimization, bullying perpetration, and combined victimization and perpetration}, series = {Journal of Aggression, Maltreatment \& Trauma}, journal = {Journal of Aggression, Maltreatment \& Trauma}, issn = {1092-6771}, doi = {10.1080/10926771.2021.1933290}, pages = {20}, abstract = {Teachers' responses to incidents of bullying among students can be important for bullying dynamics. Theoretical models of teachers' intervention competence and the theory of planned behavior suggest that teachers' bullying intervention self-efficacy may be associated with teachers' responses to bullying and students' bullying behavior and bullying victimization experiences. Several studies report an association between teachers' self-efficacy and their intervention behavior in incidents of bullying. However, the possible association with student bullying perpetration has rarely been examined so far. The current study explores the association between class teachers' self-efficacy and students' bullying victimization, perpetration, and combined bully-victim behavior in a sample of 2,071 students and their 93 class teachers in Germany. The results suggest an association between class teachers' self-efficacy and students' perpetration behavior. The higher teachers' bullying intervention self-efficacy, the fewer students seem to bully other students. In contrast, teachers' self-efficacy was not associated with students' victimization experiences and students' bully-victim behavior. Possible underlying mechanisms, as well as limitations of the present results, are discussed.

The concentration of open volume defects in the alloy, such as Sn and Ge vacancies, influences the final device performance. In this article, we present an evaluation of the point defects in molecular-beam-epitaxy grown Ge1-xSnx films treated by post-growth nanosecond-range pulsed laser melting (PLM). Doppler broadening - variable energy positron annihilation spectroscopy and variable energy positron annihilation lifetime spectroscopy are used to investigate the defect nanostructure in the Ge1-xSnx films exposed to increasing laser energy density. The experimental results, supported with ATomic SUPerposition calculations, evidence that after PLM, the average size of the open volume defects increases, which represents a raise in concentration of vacancy agglomerations, but the overall defect density is reduced as a function of the PLM fluence. At the same time, the positron annihilation spectroscopy analysis provides information about dislocations and Ge vacancies decorated by Sn atoms. Moreover, it is shown that the PLM reduces the strain in the layer, while dislocations are responsible for trapping of Sn and formation of small Sn-rich-clusters.}, language = {en} } @incollection{SchneiderFischerRumpelt, author = {Schneider, Bernd Uwe and Fischer, H. and Rumpelt, A.}, title = {Ver{\"a}nderungen von Wurzel- und Mykorrhizaz{\"o}nosen im Zuge von Waldumbaumaßnahmen}, language = {de} } @inproceedings{FischerSteinerKrakau, author = {Fischer, Thomas and Steiner, A. and Krakau, U.}, title = {Influence of nitrogen deposition on root mineralization and turnover in two Scots pine (Pinus sylvestris L.) stands in northeastern Germany}, language = {en} } @misc{ReiterRatzkeNitschetal., author = {Reiter, Sebastian and Ratzke, Markus and Nitsch, Paul-Gregor and Mai, Christian and Spirito, Davide and Corley-Wiciak, Agnieszka Anna and Wenger, Christian and Fischer, Inga A.}, title = {Optical response of titanium nitride plasmonic nanohole arrays : impact of square and hexagonal array geometry, pitch, and nanohole diameter}, series = {Plasmonics}, volume = {20}, journal = {Plasmonics}, publisher = {Springer}, address = {New York, NY}, doi = {10.1007/s11468-025-02934-4}, pages = {8825 -- 8834}, abstract = {Plasmonic nanohole arrays (NHAs) exhibit extraordinary optical transmission (EOT) evoked by resonant excitation of surface plasmons at an excitation wavelength, which is highly sensitive to changes in refractive index in the surrounding dielectric. This can enable the use of plasmonic NHAs in on-chip refractive index sensors. Such sensors can be realized on the cost-effective silicon platform by the integration of a plasmonic NHA and a Ge photodetector, provided that complementary metal-oxide-semiconductor (CMOS)-compatible materials are used for their fabrication. Titanium nitride (TiN) as a biocompatible and CMOS-compatible plasmonic transition metal nitride is well-suited for integration on the silicon platform; however, the comparatively large losses within the material require geometry optimization strategies in order to improve the optical properties of TiN NHAs for sensing. In this work, we investigated different TiN NHA geometries both in experiment and simulation. We extensively characterized square and hexagonal arrays with varying pitches and nanohole diameters and provide a detailed comparison of their optical properties. We also discuss characterization results for surface refractive index changes imposed by depositing a thin Al2O3 layer on top of the NHAs. While we do not observe a clear advantage of hexagonal arrays compared to square arrays for sensing, our results highlight the importance of geometry optimization for TiN NHAs integrated with devices.}, language = {en} }
