This paper examines the interconnectedness of soil biodiversity, climate change, and societal impacts, emphasizing the urgent need for integrated solutions. Human-induced biodiversity loss and climate change intensify environmental degradation, threatening human well-being. Soils, rich in biodiversity and vital for ecosystem function regulation, are highly vulnerable to these pressures, affecting nutrient cycling, soil fertility, and resilience. Soil also crucially regulates climate, influencing energy, water cycles, and carbon storage. Yet, climate change poses significant challenges to soil health and carbon dynamics, amplifying global warming. Integrated approaches are essential, including sustainable land management, policy interventions, technological innovations, and societal engagement. Practices like agroforestry and organic farming improve soil health and mitigate climate impacts. Effective policies and governance are crucial for promoting sustainable practices and soil conservation. Recent technologies aid in monitoring soil biodiversity and implementing sustainable land management. Societal engagement, through education and collective action, is vital for environmental stewardship. By prioritizing interdisciplinary research and addressing key frontiers, scientists can advance understanding of the soil biodiversity-climate change-society nexus, informing strategies for environmental sustainability and social equity.}, language = {en} } @misc{HerglotzOchMeyeretal., author = {Herglotz, Christian and Och, Hannah and Meyer, Anna and Ramasubbu, Geetha and Eicherm{\"u}ller, Lena and Kr{\"a}nzler, Matthias and Brand, Fabian and Fischer, Kristian and Nguyen, Dat Thanh and Regensky, Andy and Kaup, Andr{\´e}}, title = {The Bj{\o}ntegaard Bible Why Your Way of Comparing Video Codecs May Be Wrong}, series = {IEEE Transactions on Image Processing}, journal = {IEEE Transactions on Image Processing}, number = {Volume 33}, issn = {1057-7149}, doi = {10.1109/TIP.2023.3346695}, pages = {987 -- 1001}, abstract = {In this paper, we provide an in-depth assessment on the Bj{\o}ntegaard Delta. We construct a large data set of video compression performance comparisons using a diverse set of metrics including PSNR, VMAF, bitrate, and processing energies. These metrics are evaluated for visual data types such as classic perspective video, 360° video, point clouds, and screen content. As compression technology, we consider multiple hybrid video codecs as well as state-of-the-art neural network based compression methods. Using additional supporting points in-between standard points defined by parameters such as the quantization parameter, we assess the interpolation error of the Bj{\o}ntegaard-Delta (BD) calculus and its impact on the final BD value. From the analysis, we find that the BD calculus is most accurate in the standard application of rate-distortion comparisons with mean errors below 0.5 percentage points. For other applications and special cases, e.g., VMAF quality, energy considerations, or inter-codec comparisons, the errors are higher (up to 5 percentage points), but can be halved by using a higher number of supporting points. We finally come up with recommendations on how to use the BD calculus such that the validity of the resulting BD-values is maximized. Main recommendations are as follows: First, relative curve differences should be plotted and analyzed. Second, the logarithmic domain should be used for saturating metrics such as SSIM and VMAF. Third, BD values below a certain threshold indicated by the subset error should not be used to draw recommendations. Fourth, using two supporting points is sufficient to obtain rough performance estimates.}, language = {en} } @article{WallravenFischerCunninghametal., author = {Wallraven, Christian and Fischer, J. and Cunningham, Douglas William and Bartz, Dirk and B{\"u}lthoff, Heinrich H.}, title = {The Evaluation of Real-World and Computer-Generated Stylized Facial Expressions}, language = {en} } @inproceedings{WallravenFischerCunninghametal., author = {Wallraven, Christian and Fischer, J. and Cunningham, Douglas William and Bartz, Dirk and B{\"u}lthoff, Heinrich H.}, title = {The Evaluation of Stylized Facial Expressions}, series = {Proceedings, Symposium on Applied Perception in Graphics and Visualization, APGV 2006, Boston, Massachusetts, July 28 - 29, 2006}, booktitle = {Proceedings, Symposium on Applied Perception in Graphics and Visualization, APGV 2006, Boston, Massachusetts, July 28 - 29, 2006}, publisher = {ACM Press}, address = {New York, NY}, isbn = {1-59593-429-4}, pages = {85 -- 92}, language = {en} } @inproceedings{FischerCunninghamBartzetal., author = {Fischer, J. and Cunningham, Douglas William and Bartz, Dirk and Wallraven, Christian and B{\"u}lthoff, Heinrich H. and Strasser, W.}, title = {Measuring the Discernibility of Virtual Objects in Conventional and Stylized Augmented Reality}, language = {en} } @inproceedings{BartzCunninghamFischeretal., author = {Bartz, Dirk and Cunningham, Douglas William and Fischer, Jan and Wallraven, Christian}, title = {The Role of Perception for Computer Graphics}, series = {Eurographics 2008, State-of-the-Art-Reports, Crete, Greece, 2008}, booktitle = {Eurographics 2008, State-of-the-Art-Reports, Crete, Greece, 2008}, pages = {65 -- 86}, language = {en} } @misc{PieperBehnkeDumkeetal., author = {Pieper, Dawid and Behnke, Eva-Maria and Dumke, Rieke and Kehr-Fuckel, Christel and Radow, Carolin and Schulze, Nils and Follmann, Markus and Schaefer, Corinna and Prill, Robert and Kopkow, Christian and Bahns, Carolin and Choi, Kyung-Eun (Anna) and Fischer, Lena}, title = {Awareness of adapting clinical practice guidelines to a local context}, series = {Clinical and public health guidelines}, volume = {2}, journal = {Clinical and public health guidelines}, number = {3}, publisher = {Wiley}, address = {Hobken, New Jersey}, issn = {2836-3973}, doi = {10.1002/gin2.70025}, pages = {1 -- 7}, abstract = {Background Guideline recommendations are often not implemented in practice. This can be attributed to factors such as patient preferences and characteristics, structural conditions, personnel or other resources, as well as cultural or ethical aspects. Adaptations to the local context (e.g., regional or hospital) result in so-called locally adapted guidelines (LAGL), which could improve implementation. We aimed to assess the awareness of LAGL among guideline developers in Germany. Methods An online survey was conducted via LimeSurvey in May 2024. The questionnaire, designed based on literature and expert opinions, consisted of 23 items, predominantly with dichotomous response options. Recruitment was conducted via email. Direct contact addresses were identified using the German guideline registry (n = 397). Additionally, a mailing list distribution was conducted through the guidelines working group of the German Network for Evidence-Based Medicine (n = 316). Only fully completed questionnaires were included in the analysis. Data cleaning and descriptive analysis were performed using Excel. Results A total of 63 questionnaires were fully completed. The most represented groups were physicians (65\%) and methodologists (24\%), most frequently in coordination (76\%) or as group members (62\%). The most judicious reasons for developing a LAGL were differences in patient populations (48\%), currency of recommendations (46\%), and patient values and preferences (44\%). The most commonly cited likely reasons for developing a LAGL were economic considerations (32\%), differences in patient populations (30\%), and currency of recommendations (30\%). Many respondents (59\%) were aware of the possibility of adapting existing guidelines to the local context. Among these, approximately half (49\%) had already locally adapted a guideline, with 75\% using an adaptation framework. Discussion LAGLs are known among guideline developers in Germany and are generally developed using adaptation frameworks. Potential reasons for preparing LAGLs are diverse, with some discrepancies between perceived valid and likely reasons. Highlights Over half (59\%) of surveyed clinical practice guideline (CPG) developers in Germany were aware of the possibility of adapting CPGs to local contexts, and nearly half of them had practical experience doing so. Although several adaptation frameworks exist, only 44\% of experienced adaptors were familiar with them, and among users, many found them only partly helpful. Differences in patient populations, outdated recommendations, and patient values were rated as the most valid reasons for local CPG adaptation, while economic factors were seen as the most likely driver in practice. Despite existing awareness, guideline adaptation to local settings remains underutilized and lacks structured implementation, highlighting the need for clearer definitions, better resources, and more practical examples.}, language = {en} } @misc{KalraAlvaradoChavarinNitschetal., author = {Kalra, Amanpreet and Alvarado Chavarin, Carlos and Nitsch, Paul-Gregor and Tschammer, Rudi and Flege, Jan Ingo and Ratzke, Markus and Zoellner, Marvin Hartwig and Schubert, Markus Andreas and Wenger, Christian and Fischer, Inga Anita}, title = {Deposition of CeOₓ/SnOₓ-based thin films via RF magnetron sputtering for resistive gas sensing applications}, series = {Physica B, Condensed matter}, volume = {723}, journal = {Physica B, Condensed matter}, publisher = {Elsevier BV}, address = {Amsterdam}, issn = {0921-4526}, doi = {10.1016/j.physb.2025.418098}, pages = {1 -- 7}, abstract = {Cerium oxide-tin oxide (CeOx/SnOx) thin films with varying Sn content were deposited using RF magnetron sputtering and investigated for hydrogen sensing applications.

Gas sensing measurements showed effective hydrogen detection at room temperature, with the sensitivity strongly influenced by Sn content and oxygen vacancy concentration. Higher Sn concentration enhanced the sensing response, which was correlated with microstructural features obtained from AFM and EDX, as well as with the presence of Ce3+ and Ce4+ oxidation states identified by XPS.

With a corresponding functionalization of the TiN nanohole arrays, these ultra-compact devices can be utilized in the development of various affinity sensors and sensor systems, such as cost-effective electronic noses for the early detection of gases in the food industry or agriculture. In this work, we focus on two types of coating for functionalization of TiN nanohole arrays: electrochemically synthesized poly-N-methylaniline and layer-by-layer deposited polyacrylic-acid/poly-allylamine (PAA/PAH). Our investigation comprises the experimental characterization of the optical properties of TiN nanhole arrays coated with polymer layers of different thicknesses as well as a comparison with simulation results. We demonstrate the potential of our setup sensing applications by measuring changes in optical properties of TiN nanohole arrays coated with PAA/PAH upon exposure to air of different humidity.}, language = {en} }
