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{KleefeldReissel, author = {Kleefeld, Andreas and Reißel, Martin}, title = {The Levenberg-Marquardt method applied to a parameter estimation problem arising from electrical resistivity tomography}, series = {Journal of Applied Mathematics and Computation}, volume = {217}, journal = {Journal of Applied Mathematics and Computation}, number = {9}, issn = {0096-3003}, pages = {4490 -- 4501}, abstract = {An efficient and robust electrical resistivity tomographic inversion algorithm based on the Levenberg-Marquardt method is considered to obtain quantities like grain size, source discrimination and particle size distribution. The corresponding model in two-dimensions is based on the Maxwell equations and leads to a partial differential equation with mixed Dirichlet-Neumann boundary conditions. The forward problem is solved numerically with the finite-difference method. However, the inverse problem at hand is a classic nonlinear and ill-posed parameter estimation problem. Linearizing it and applying the Tikhonov regularization method yields an iterative scheme, the Levenberg-Marquardt method. Several systems of equations of large size have to be solved efficiently in each iteration step which is accomplished by the conjugate gradient method without setting up the corresponding matrix. Instead fast matrix-vector multiplications are performed directly. Therefore, the derivative and its adjoint for the parameter-to-solution map are needed. Numerical results demonstrate the performance of our method as well as the possibility to reconstruct some of the desired parameters.}, language = {en} } @misc{HoZschechSchmeisseretal., author = {Ho, Paul S. and Zschech, Ehrenfried and Schmeißer, Dieter and Meyer, Moritz Andreas and Huebner, Rene and Hauschildt, Meike and Zhang, Lijuan and Gall, Martin and Kraatz, Matthias}, title = {Scaling effects on microstructure and reliability for cu interconnects}, language = {en} } @misc{WaetzoldDrechslerArmstrongetal., author = {W{\"a}tzold, Frank and Drechsler, Martin and Armstrong, Claire W. and Baumg{\"a}rtner, Stefan and Grimm, Volker and Huth, Andreas and Perrings, Charles and Possingham, Hugh P. and Shogren, Jason F. and Skonhoft, Anders and Verboom-Vasiljev, Jana and Wissel, Christian}, title = {Ecological-economic modeling for biodiversity management: Potential, pitfalls, prospects}, language = {en} } @misc{SchlofferIqbalGabrischetal., author = {Schloffer, Martin and Iqbal, Farasat and Gabrisch, Heike and Schwaighofer, Emanuel and Schimansky, Frank-Peter and Mayer, Svea and Stark, Andreas and Lippmann, Thomas and G{\"o}ken, Mathias and Pyczak, Florian and Clemens, Helmut}, title = {Microstructure development and hardness of a powder metallurgical multi phase gamma-TiAl based alloy}, series = {Intermetallics}, journal = {Intermetallics}, number = {22}, issn = {0966-9795}, doi = {10.1016/j.intermet.2011.11.015}, pages = {231 -- 240}, language = {en} } @inproceedings{HauschildtStarkLorenzetal., author = {Hauschildt, Katja and Stark, Andreas and Lorenz, Uwe and Schell, Norbert and Fischer, Torben and Blankenburg, Malte and M{\"u}ller, Martin and Pyczak, Florian}, title = {Diffusion brazing of γ-TiAl-alloys: Investigations of the joint by electron microscopy and high-energy X-ray diffraction}, series = {Intermetallic-based alloys - science, technology and applications, symposium held November 25-30, Boston, Massachusetts, U.S.A}, booktitle = {Intermetallic-based alloys - science, technology and applications, symposium held November 25-30, Boston, Massachusetts, U.S.A}, publisher = {Cambridge Univ.

We investigate the applicability of this framework to the construction of color-valued median filters. Additionally, we introduce spatial adaptivity into our approach by morphological amoebas that offer excellent capabilities for structure-preserving filtering. Furthermore, we define color-valued amoeba M-smoothers as a generalization of the median-based concepts. Our experiments confirm that all these methods work well with color images.

Based on the characterisation results, state-of-the-art treatment technologies have been combined to design an optimised recycling and upgrade process for each input fraction. High-impact polystyrene from TV casings that complies with the European directive on the restriction of hazardous substances (RoHS) was produced by applying continuous density separation with yields of about 60\%. Valuable acrylonitrile butadiene styrene/ polycarbonate can be extracted from monitor and printer casings by near- infrared-based sorting.

Thus, obtained polymers demonstrated high sensitivity to HCl in the parts per million concentration range. Kinetics of the gaseous HCl influence on the ratios of conductivities measured by 2- and 4-point techniques was analyzed. Some response of the polymers conductance towards NH3, NO and oxygen was also observed, but with much lower sensitivity than towards HCl. In aqueous solutions, the polymer conductivity was pH dependent; in comparison with 4,4′-dibuthoxy-2,2′-bipyrrole, the conductivity range of the methoxy derivative was shifted to acidic range for about two pH units.

In a total of > 1000 breast cancer patients of two independent data sets we showed a) that KCNJ3 expression is upregulated in tumor tissue compared to corresponding normal tissue (p < 0.001), b) that KCNJ3 expression is associated with estrogen receptor (ER) positive tumors (p < 0.001), but that KCNJ3 expression is variable within this group, and c) that ER positive patients with high KCNJ3 levels have worse overall (p < 0.05) and disease free survival probabilities (p < 0.01), whereby KCNJ3 is an independent prognostic factor (p <0.05).
