This inverse problem is implemented as a nonlinear regression-type optimization problem, in which the simulation signals are fitted to the measurement signals. These signals consist of displacement responses in waveguides, focusing on hollow cylindrical geometries to enhance the simulation efficiency. To accelerate the optimization and reduce the number of model evaluations and wait times, we propose two novel methods. First, we introduce an adaptation of the Levenberg–Marquardt method derived from a geometrical interpretation of the least-squares optimization problem. Second, we introduce an improved objective function based on the autocorrelated envelopes of the measurement and simulation signals. Given that this study primarily relies on simulation data to quantify optimization convergence, we aggregate the expected ranges of realistic material parameters and derive their distributions to ensure the reproducibility of optimizations with proper measurements. We demonstrate the effectiveness of our objective function modification and step adaptation for various materials with isotropic material symmetry by comparing them with the Broyden–Fletcher–Goldfarb–Shanno method. In all cases, our method reduces the total number of model evaluations, thereby shortening the time to identify the material parameters."}],"date_created":"2026-01-29T08:53:42Z","title":"A modified Levenberg–Marquardt method for estimating the elastic material parameters of polymer waveguides using residuals between autocorrelated frequency responses","year":"2026","_id":"63800","project":[{"_id":"89","name":"Vollständige Bestimmung der akustischen Materialparameter von Polymeren"}],"department":[{"_id":"49"}],"user_id":"32616","type":"journal_article","status":"public","oa":"1","date_updated":"2026-02-02T12:44:47Z","volume":247,"author":[{"full_name":"Itner, Dominik","last_name":"Itner","first_name":"Dominik"},{"last_name":"Dreiling","full_name":"Dreiling, Dmitrij","id":"32616","first_name":"Dmitrij"},{"full_name":"Gravenkamp, Hauke","last_name":"Gravenkamp","first_name":"Hauke"},{"first_name":"Bernd","id":"213","full_name":"Henning, Bernd","last_name":"Henning"},{"last_name":"Birk","full_name":"Birk, Carolin","first_name":"Carolin"}],"doi":"https://doi.org/10.1016/j.ymssp.2026.113904","main_file_link":[{"open_access":"1","url":"https://www.sciencedirect.com/science/article/pii/S0888327026000610/pdfft?md5=16e8493b44527f4ab0a6d13f634a01c3&pid=1-s2.0-S0888327026000610-main.pdf"}],"publication_identifier":{"issn":["0888-3270"]},"publication_status":"published","intvolume":"       247","page":"113904","citation":{"apa":"Itner, D., Dreiling, D., Gravenkamp, H., Henning, B., &#38; Birk, C.

Understanding tax complexity in this context is crucial as developing nations frequently encounter legislative, fiscal, and administrative challenges that exacerbate their tax complexity. Complexity can hinder investment, impair tax revenue collection, and impede economic development. The authors adapt a global survey instrument to the Indonesian context and collect responses from Indonesian tax officers and firms. Transfer pricing is perceived as the most complex tax regulation which is consistent with cross-country studies. However, in contrast to the global findings, statutory tax rates and taxes on dividends rank second and third in Indonesia. While Indonesian tax officers emphasize the complexity of transfer pricing regulations, firms are more concerned about the complexity of tax procedures, especially tax guidance and tax audits. Furthermore, comparative analyses show that tax officers perceive tax regulations as being more complex than tax procedures. In contrast, firms perceive the opposite, particularly for tax audits. The findings offer a nuanced picture of tax complexity in a developing country and provide guidance for tax reforms in Indonesia. They also serve as a commencement for further analyses of developing countries."}],"department":[{"_id":"187"}],"user_id":"97894","_id":"56815","language":[{"iso":"eng"}]},{"language":[{"iso":"eng"}],"keyword":["tet_topic_opticalantenna","tet_topic_numerics","tet_topic_meta"],"publication":"Photonics","abstract":[{"text":"Light-emitting diodes (LEDs) are becoming increasingly important across various sectors of the lighting industry and are being used more frequently. In the field of symbolic projection, research is increasingly focusing on implementing light modulation using energy-efficient, incoherent LEDs rather than lasers. Since light modulation in micro- and nano-optics is typically achieved through phase modulation, Finite-Difference Time-Domain (FDTD) simulations are employed for analysis. The objective of this article is to investigate different approaches for approximating incoherent monochromatic light sources within FDTD simulations. To this end, two approaches based on dipole sources are considered, as well as a method involving plane waves with modulated wavefronts based on Cosine–Fourier functions and a method based on the superposition of Gaussian beams.

Using naturalistic observations of the portfolio work within the seminar, effects and developments were recorded. With partly quantitative, predominantly qualitative content analyses of the portfolios, concrete connections between learning contents were determined. The explorative study shows changed perspectives and peaked interests of the students because of portfolio work as well as diverse contextualisations, comparisons and connections in the portfolios, thus offering a possible starting point for structural recommendations for the discipline of comparative literary and cultural studies."}],"publication":"die hochschullehre: Interdisziplinäre Zeitschrift für Studium und Lehre"},{"keyword":["DC-grid","Droop control","Grid-serving behaviour","Grid stability","Bidirectional charging","Sequential decision","MILP optimisation"],"article_number":"100227","article_type":"original","language":[{"iso":"eng"}],"_id":"63838","department":[{"_id":"644"}],"user_id":"56955","abstract":[{"lang":"eng","text":"Industrial electrification is increasing to reduce fossil fuel dependence, alongside a growing share of volatile renewables.\r\nA secure and reliable energy supply is crucial for industry, leading to a shift from centralised to decentralised grid structures.\r\nDC microgrids becoming increasingly popular in industry, since they enable energy recuperation from braking, reduce components and cables, and integrate storage and local generation to manage supply interruptions or peak loads.\r\nEVs add further synergies by serving as mobile storage units, helping to store and redistribute locally generated renewable energy.\r\nThis paper analyses how EV integration in droop-controlled DC grids can contribute to a more stable, low-emission and peak-reduced load profile to the supply grid through load shifting and bridge interruptions.\r\nA droop-controlled DC grid model has been developed, incorporating an EV charging park based on probability functions.\r\nScalable scenarios allow for diverse condition analysis using an energy management system that utilises fuzzy logic and sequential MILP optimisation.\r\nIt has been shown that a 7% improvement of coefficient represented grid-serving behaviour is possible by load shifting.\r\nIt has also been demonstrated that an optimised EMS can reduce the demand-based CO2 emissions by 41kg for a representative day compared to a fuzzy logic EMS.\r\nAt the same time peak load is decreased yielding a more constant residual load.\r\nThese results highlight the potential of a controlled bidirectional charging infrastructure in DC grids and underscore the need to explicitly consider charging processes to ensure a residual load as constant as possible."}],"status":"public","publication":"Smart Energy","type":"journal_article","title":"Analysis of bidirectional EV charging infrastructures within industrial DC grids","doi":"10.1016/j.segy.2026.100227","date_updated":"2026-02-03T12:58:44Z","publisher":"Elsevier BV","author":[{"last_name":"Rahlf","orcid":"0009-0006-8106-2132","id":"56955","full_name":"Rahlf, Henning Christoph","first_name":"Henning Christoph"},{"first_name":"Lukas","id":"90391","full_name":"Knorr, Lukas","orcid":"0009-0005-4727-7511","last_name":"Knorr"},{"first_name":"Simon","full_name":"Althoff, Simon","last_name":"Althoff"},{"first_name":"Henning","last_name":"Meschede","orcid":"0000-0002-1538-089X","id":"86954","full_name":"Meschede, Henning"}],"date_created":"2026-02-02T14:45:17Z","year":"2026","citation":{"ama":"Rahlf HC, Knorr L, Althoff S, Meschede H.

Continuous Value Shaping emerges as a conceptual extension to service systems engineering, promoting more adaptive and co-evolutionary forms of service system development. This study examines how Continuous Value Shaping manifests through a multiple case study of three public sector projects. We identify distinct manifestations and constellations of the concept’s principles that complement classical\r\nSSE practices. As the first empirical exploration of Continuous Value Shaping, the study refines its\r\nconceptual foundation and enhances its accessibility for researchers and practitioners.

This study introduces sulfonated phenylene-bridged periodic mesoporous organosilicas (PMOs) as promising inorganic–organic hybrid PEMs, synthesized via surfactant-templating with varying alkyl chain lengths for different mesopore sizes. Post-synthetic functionalization involves nitration of phenylene moieties, reduction to amines, and ring-opening of propane or butane sultones to graft sulfonic acid groups via flexible spacers, achieving homogeneous distribution along pore walls. Post-functionalization is confirmed by powder X-ray diffraction (PXRD), revealing preserved 2D hexagonal p6mm ordering and phenylene stacking. N2 physisorption shows type IV isotherms with reduced pore volumes and pore sizes. 1H NMR is used to quantify functionalization degrees. Impedance spectroscopy on pressed pellets demonstrates proton conductivities up to 2 × 10−3 S cm−1 at 30 °C and 90% RH, depending on the functionalization degree, confirming sulfonic acid-mediated conduction.","lang":"eng"}],"publication":"Nanomaterials","title":"Proton-Conducting Sulfonated Periodic Mesoporous Organosilica","publisher":"MDPI AG","date_created":"2026-02-05T09:46:20Z","year":"2026","quality_controlled":"1","issue":"3","article_number":"203","_id":"63883","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"user_id":"23547","status":"public","type":"journal_article","doi":"10.3390/nano16030203","main_file_link":[{"open_access":"1"}],"oa":"1","date_updated":"2026-02-05T09:48:27Z","volume":16,"author":[{"full_name":"Wagner, Tobias","last_name":"Wagner","first_name":"Tobias"},{"first_name":"Michael","full_name":"Tiemann, Michael","id":"23547","orcid":"0000-0003-1711-2722","last_name":"Tiemann"}],"intvolume":"        16","citation":{"ama":"Wagner T, Tiemann M.

Existing post-hoc explanation methods lack support for actual node features beyond one-hot encoding of node type and often fail to generate realistic, faithful explanations. To address these gaps, we propose DiGNNExplainer, a model-level explanation approach that synthesizes heterogeneous graphs with realistic node features via discrete denoising diffusion. In particular, we generate realistic discrete features (e.g., bag-of-words features) using diffusion models within a discrete space, whereas previous approaches are limited to continuous spaces. We evaluate our approach on multiple datasets and show that DiGNNExplainer produces explanations that are realistic and faithful to the model's decision-making, outperforming state-of-the-art methods."}],"department":[{"_id":"760"}],"user_id":"11871","external_id":{"arxiv":["2508.08458"]},"_id":"63918","language":[{"iso":"eng"}]},{"date_created":"2026-02-06T06:43:22Z","publisher":"Association for Computing Machinery","title":"SORCERI: Streaming Overlay Acceleration for Highly Contracted Electron Repulsion Integral Computations in Quantum Chemistry","year":"2026","language":[{"iso":"eng"}],"keyword":["electron repulsion integrals","quantum chemistry","atomistic simulation","overlay architecture","fpga acceleration"],"publication":"Proceedings of the 2026 ACM/SIGDA International Symposium on Field Programmable Gate Arrays (FPGA '26)","abstract":[{"lang":"eng","text":"The computation of highly contracted electron repulsion integrals (ERIs) is essential to achieve quantum accuracy in atomistic simulations based on quantum mechanics. Its growing computational demands make energy efficiency a critical concern. Recent studies demonstrate FPGAs’ superior performance and energy efficiency for computing primitive ERIs, but the computation of highly contracted ERIs introduces significant algorithmic complexity and new design challenges for FPGA acceleration.In this work, we present SORCERI, the first streaming overlay acceleration for highly contracted ERI computations on FPGAs. SORCERI introduces a novel streaming Rys computing unit to calculate roots and weights of Rys polynomials on-chip, and a streaming contraction unit for the contraction of primitive ERIs. This shifts the design bottleneck from limited CPU-FPGA communication bandwidth to available FPGA computation resources. To address practical deployment challenges for a large number of quartet classes, we design three streaming overlays, together with an efficient memory transpose optimization, to cover the 21 most commonly used quartet classes in realistic atomistic simulations. To address the new computation constraints, we use flexible calculation stages with a free-running streaming architecture to achieve high DSP utilization and good timing closure.Experiments demonstrate that SORCERI achieves an average 5.96x, 1.99x, and 1.16x better performance per watt than libint on a 64-core AMD EPYC 7713 CPU, libintx on an Nvidia A40 GPU, and SERI, the prior best-performing FPGA design for primitive ERIs. Furthermore, SORCERI reaches a peak throughput of 44.11 GERIS (109 ERIs per second) that is 1.52x, 1.13x, and 1.93x greater than libint, libintx and SERI, respectively.
