Apart from manual testing, no standardized method is currently available. Proper quantification of patella mobility is necessary to better understand pathologies at the patellofemoral joint. Patella mobility was assessed in 25 healthy individuals using a Patellostabilometer, a new prototype instrument for quantification of the mediolateral patella displacement. The participants underwent measurements of the mediolateral displacement three times using the Patellostabilome- ter. A maximal force of 10 N was applied for patella movement. Additionally, leg length and circumference of the knee, upper- and lower-leg were measured. Lateral patella displacement of 18.27 ± 3.76 mm (range 15.85-20.64 mm, interquartile range (IQR) of 4.79) was measured. The medial patella displacement showed 24.47 ± 6.59 mm (range 19.29-29.76 mm, IQR of 10.47). The test-retest measurement error was 2.32 ± 1.76 mm (IQR of 2.38 mm), with five outliers. There was greater test-retest variability between the measurements of the medial displacement compared to the lateral one. The test-retest variability reached 7\% of the patella displacement. Other parameters provided no significant correlations. Based on the natural patellofemoral mobility, a precise and clinically relevant quantification of patella mobility is allowed.}, language = {en} } @article{RizunRevinaEdelmann2023, author = {Rizun, Nina and Revina, Aleksandra and Edelmann, Noella}, title = {Application of Text Analytics in Public Service Co-Creation: Literature Review and Research Framework}, series = {DG.O 2023: The 24th Annual International Conference on Digital Government Research}, journal = {DG.O 2023: The 24th Annual International Conference on Digital Government Research}, publisher = {Association for Computing Machinery}, doi = {10.1145/3598469.3598471}, pages = {12 -- 22}, year = {2023}, abstract = {The public sector faces several challenges, such as a number of external and internal demands for change, citizens' dissatisfaction and frustration with public sector organizations, that need to be addressed. An alternative to the traditional top-down development of public services is co-creation of public services. Co-creation promotes collaboration between stakeholders with the aim to create better public services and achieve public values. At the same time, data analytics has been fuelled by the availability of immense amounts of textual data. Whilst both co-creation and TA have been used in the private sector, we study existing works on the application of Text Analytics (TA) techniques on text data to support public service co-creation. We systematically review 75 of the 979 papers that focus directly or indirectly on the application of TA in the context of public service development. In our review, we analyze the TA techniques, the public service they support, public value outcomes, and the co-creation phase they are used in. Our findings indicate that the TA implementation for co-creation is still in its early stages and thus still limited. Our research framework promotes the concept and stimulates the strengthening of the role of Text Analytics techniques to support public sector organisations and their use of co-creation process. From policy-makers' and public administration managers' standpoints, our findings and the proposed research framework can be used as a guideline in developing a strategy for the designing co-created and user-centred public services.}, language = {en} } @article{Guterding2023, author = {Guterding, Daniel}, title = {Sparse Modeling Approach to the Arbitrage-Free Interpolation of Plain-Vanilla Option Prices and Implied Volatilities}, series = {Risks}, journal = {Risks}, number = {11 (5)}, publisher = {MDPI AG}, doi = {https://doi.org/10.3390/risks11050083}, pages = {24}, year = {2023}, abstract = {We present a method for the arbitrage-free interpolation of plain-vanilla option prices and implied volatilities, which is based on a system of integral equations that relates terminal density and option prices. Using a discretization of the terminal density, we write these integral equations as a system of linear equations. We show that the kernel matrix of this system is, in general, ill-conditioned, so that it cannot be solved for the discretized density using a naive approach. Instead, we construct a sparse model for the kernel matrix using singular value decomposition (SVD), which allows us not only to systematically improve the condition number of the kernel matrix, but also determines the computational effort and accuracy of our method. In order to allow for the treatment of realistic inputs that may contain arbitrage, we reformulate the system of linear equations as an optimization problem, in which the SVD-transformed density minimizes the error between the input prices and the arbitrage-free prices generated by our method. To further stabilize the method in the presence of noisy input prices or arbitrage, we apply an 𝐿1-regularization to the SVD-transformed density. Our approach, which is inspired by recent progress in theoretical physics, offers a flexible and efficient framework for the arbitrage-free interpolation of plain-vanilla option prices and implied volatilities, without the need to explicitly specify a stochastic process, expansion basis functions or any other kind of model. We demonstrate the capabilities of our method in a number of artificial and realistic test cases.}, language = {en} } @article{StannariusHarth2023, author = {Stannarius, Ralf and Harth, Kirsten}, title = {The structure of disintegrating defect clusters in smectic C freely suspended films}, series = {Soft Matter}, journal = {Soft Matter}, number = {19}, publisher = {Royal Society of Chemistry}, doi = {https://doi.org/10.1039/d3sm00808h}, pages = {6109 -- 6115}, year = {2023}, abstract = {Disclinations or disclination clusters in smectic C freely suspended films with topological charges larger than one are unstable.

We analyze experimental data and compare them with a simple model where the defect clusters adiabatically pass quasi-equilibrium solutions in one-constant approximation. It is found that the defects arrange in geometrical patterns that correspond very closely to superimposed singular defect solutions, without additional director distortions. The patterns expand by affine transformations where all distances between individual defects scale with the same time-dependent scaling factor proportional to the square-root of time.}, language = {en} } @article{XuShimizuGuterdingetal.2023, author = {Xu, Han-Xiang and Shimizu, Makoto and Guterding, Daniel and Otsuki, Junya and Jeschke, Harald O.}, title = {Pressure evolution of electronic structure and magnetism in the layered van der Waals ferromagnet CrGeTe3}, series = {Physical Review B}, journal = {Physical Review B}, number = {Vol. 108}, publisher = {American Physical Society}, doi = {https://doi.org/10.1103/PhysRevB.108.125142}, pages = {15}, year = {2023}, abstract = {Layered van der Waals ferromagnets, which preserve their magnetic properties down to exfoliated monolayers, are fueling an abundance of fundamental research and nanoscale device demonstration.

The second phase involves the dissolution of a thin nematic film between the two isotropic cores.

A novel chromatographic sensor was developed with a deep UV LED-based photometric detection unit (255-265 nm), an original flow cuvette and registration scheme; the processing of a chromatogram with the sensor takes approximately 15 min. Strict isochronism between the elution of ATP metabolites, mainly hypoxanthine (Hx) and inosine monophosphate (IMP), and the time of maturation of meat or fish, was discovered. A new freshness index H* = [Hx]/[IMP] was introduced, which is proportional to the instrumental delay time in the FPMLC chromatograms: the H* index < 0.5 indicates the presence of inosine monophosphate (IMP) and the high quality of the meat or fish. Reasonably strong correlations were revealed between data obtained by FPMLC and total volatile basic nitrogen TVB-N (for fish) or volatile fatty acids VFA (for meat) content. Moreover, putative nucleotide salvage and an increase in the concentration of IMP were observed in fish after heat treatment using the FPMLC sensor and NMR technique.}, language = {en} } @article{KristalWeretecki2024, author = {Kristal, Samuel and Weretecki, Patrick}, title = {Social first?

Among new photodetector types are photosensitive structures based on cascade concentrators, whose operational principle involves the absorption of optical radiation followed by its reemission at a longer wavelength and radiation concentration onto a highly efficient small-area photodetector. The absorption and re-emission spectra of each cascade layer depend on the characteristics of the material used. Сolloidal quantum dots are among the most promising materials for cascade layers due to their manufacturing technology, which provides for accurate control over the photoluminescence maximum position. It seems highly relevant to develop and to study photosensitive structures with cascade concentrators of various shapes based on CdS, CdSe/ZnS, and PbS colloidal quantum dots. Aim . To develop photosensitive structures with a wide-range sensitivity spectrum based on concentrators containing arrays of metal chalcogenide CQDs and to study their characteristics. Materials and methods . Cascade photosensitive structures were manufactured based on layers made of polymethyl methacrylate and layers of colloidal quantum dots embedded in a polystyrene matrix. Results . Three-layer concentrators were manufactured with different colloidal quantum dots in each concentrator layers. A 22 \% increase in the output power was observed for a three-layer cascade structure based on different cascade layer materials compared to a similar structure using a single layer concentrator. Conclusion . The conducted studies showed an increase in the efficiency of photosensitive structures with a cascade concentrator based on colloidal quantum dots of various types (CdS, CdSe/ZnS, and PbS) in the cascade layers.}, language = {ru} } @article{CatalanoNaselloGuterding2024, author = {Catalano, Francesco and Nasello, Laura and Guterding, Daniel}, title = {Quantum Computing Approach to Realistic ESG-Friendly Stock Portfolios}, series = {Risks}, volume = {12}, journal = {Risks}, number = {4}, publisher = {MDPI}, issn = {2227-9091}, doi = {10.3390/risks12040066}, pages = {1 -- 12}, year = {2024}, abstract = {Finding an optimal balance between risk and returns in investment portfolios is a central challenge in quantitative finance, often addressed through Markowitz portfolio theory (MPT). While traditional portfolio optimization is carried out in a continuous fashion, as if stocks could be bought in fractional increments, practical implementations often resort to approximations, as fractional stocks are typically not tradeable. While these approximations are effective for large investment budgets, they deteriorate as budgets decrease. To alleviate this issue, a discrete Markowitz portfolio theory (DMPT) with finite budgets and integer stock weights can be formulated, but results in a non-polynomial (NP)-hard problem. Recent progress in quantum processing units (QPUs), including quantum annealers, makes solving DMPT problems feasible. Our study explores portfolio optimization on quantum annealers, establishing a mapping between continuous and discrete Markowitz portfolio theories. We find that correctly normalized discrete portfolios converge to continuous solutions as budgets increase. Our DMPT implementation provides efficient frontier solutions, outperforming traditional rounding methods, even for moderate budgets. Responding to the demand for environmentally and socially responsible investments, we enhance our discrete portfolio optimization with ESG (environmental, social, governance) ratings for EURO STOXX 50 index stocks. We introduce a utility function incorporating ESG ratings to balance risk, return and ESG friendliness, and discuss implications for ESG-aware investors.}, language = {en} } @article{RichterSchwarzCreutzburg2021, author = {Richter, Maximilian and Schwarz, Klaus and Creutzburg, Reiner}, title = {Conception and Implementation of Professional Laboratory Exercises in the field of ICS/SCADA Security - Part I: Fundamentals}, series = {Electronic imaging}, journal = {Electronic imaging}, publisher = {Society for Imaging Science and Technology}, doi = {10.2352/ISSN.2470-1173.2021.3.MOBMU-073}, pages = {73-1 -- 73-13}, year = {2021}, language = {en} } @article{WangHarthPuzyrevetal.2022, author = {Wang, Jing and Harth, Kirsten and Puzyrev, Dmitry and Stannarius, Ralf}, title = {The effect of obstacles near a silo outlet on the discharge of soft spheres}, series = {New Journal of Physics}, volume = {24}, journal = {New Journal of Physics}, publisher = {IOP}, doi = {10.1088/1367-2630/ac8bea}, year = {2022}, language = {en} } @article{RegehlyHecht2022, author = {Regehly, Martin and Hecht, Stefan}, title = {Auf dem Weg zum Replikator}, series = {Physik in unserer Zeit}, volume = {53}, journal = {Physik in unserer Zeit}, number = {3}, publisher = {Wiley-VCH GmbH}, issn = {1521-3943}, doi = {10.1002/piuz.202201637}, pages = {125 -- 131}, year = {2022}, language = {de} } @article{ScheegScheeg2019, author = {Scheeg, Jochen and Scheeg, Manuela}, title = {Digitale L{\"o}sungen passend f{\"u}r den Nutzer gestalten}, series = {Wissenschaft trifft Praxis : Usability betrieblicher IT-Anwendungen}, journal = {Wissenschaft trifft Praxis : Usability betrieblicher IT-Anwendungen}, number = {11.2019}, publisher = {Begleitforschung Mittelstand-Digital}, issn = {2198-8544}, pages = {32 -- 38}, year = {2019}, language = {de} } @inproceedings{WikarskiAurahEbingaOsoreetal.2021, author = {Wikarski, Dietmar and Aurah, Catherine and Ebinga Osore, Emmanuel and Mengich, Gladys and Mutua, Gershom and Ndiema, Alice and Nkangi, Felister Nyaera and Ogemah, Vitalis and Okoth, Patrick and Ondulo, Jasper and Orata Omoto, Francis and Wambui Mwangi, Mary and Namayi, Vivian and Flassig, Peter and Loose, Harald and Malessa, Reiner and Piorr, Hans-Peter and Schrader, Thomas and Weber, Christian-Toralf}, title = {Towards Practice-oriented Higher Education for Sustainable Rural Development in Western Kenya}, editor = {Wikarski, Dietmar}, edition = {1st edition}, publisher = {Technische Hochschule Brandenburg}, address = {Brandenburg an der Havel}, organization = {Technische Hochschule Brandenburg}, doi = {10.25933/opus4-2742}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-27420}, year = {2021}, abstract = {The workshop proceedings contain the written versions of the presentations of the Kenyan participants of the final workshop of the DAAD-funded cooperation project "Practice-oriented Higher Education in Western Kenya" (ProUniEdu-WeK) in August 2021 at the Brandenburg University of Applied Sciences (THB).

The Meclib concept mitigates this complexity and allows for efficient bulk production of material with consistent appearance and user experience. The core of Meclib is a set of pre-defined JSXGraph-based objects with an interface to Maxima, such that no problem specific JS code is required at all.

For this purpose, a general understanding of the terms "globalization" and "deglobalization" will be provided. In addition, the drivers and challenges of (de)globalization are explained in more detail. The question was then examined based on specific case studies, which are decisive for today's prosperity and are predominantly imported. This includes gases, oils, and rare earths. The paper distinguishes between the effects of a loss of these resources on Germany, if the deglobalization takes place slowly and planned or unplanned and fast. The effects are then considered at three different levels: at the government level, at the corporate level, and at the population level. At the corporate level, the focus was primarily on the largest German industries. Each of the case studies ends with possible hypothetical scenarios that do not have to happen but could happen in the worst case. The scenarios show how bad things can get and provide an answer to the scientific question of how deglobalization in the case study could affect Germany.}, subject = {Nat{\"u}rliche Ressourcen}, language = {en} } @article{BaeckerAlabbadiYogiputraetal.2023, author = {Baecker, Christoph and Alabbadi, Osama and Yogiputra, Georgius Pradipta and Tien Dung, Nguyen}, title = {Threats provided by artificial intelligence that could disrupt the democratic system}, publisher = {Technische Hochschule Brandenburg}, doi = {10.25933/opus4-2898}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-28988}, pages = {17 Seiten}, year = {2023}, abstract = {This research paper examines the potential consequences of AI technology on democratic systems.

The paper examines the ways in which AI can be used to supervise, manipulate, and frustrate the media, thereby weakening its role as a check on government and corporate power. The study also explores how AI technology can be used to create an "omnidirectional monitoring" society, where individuals are constantly monitored and controlled through the use of "panopticon" techniques and "social bots". This can lead to the emergence of a "postdemocratic" society, characterized by growing inequality, dehumanization, and the manipulation of information on online media platforms. The research methodology adopted in the study is qualitative, using expert interviews with three experts who discussed the overall use of AI and its disruptive effects on democracy, such as the creation of fake news, filter bubbles, and algorithm bias. In conclusion, this research highlights the need for increased awareness and regulation of AI technology to ensure its responsible use and to protect democratic values.}, subject = {K{\"u}nstliche Intelligenz}, language = {en} } @misc{GarzonGilIngabireKibathi2023, type = {Master Thesis}, author = {Garz{\´o}n Gil, Zahira and Ingabire, Noella Arlette and Kibathi, Patrick}, title = {Disruption of Africa's education systems and economic development due to overpopulation}, doi = {10.25933/opus4-2890}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-28909}, school = {Technische Hochschule Brandenburg}, year = {2023}, abstract = {Education lies at the foot of economic growth and human development. However, an increase in population tends to put a strain on existing education systems, especially in Africa where most countries are characterized by slow economic development, rapid population growth rates and a median age just shy of 20 years. Due to the slow rate of economic growth, many African countries lack the financial capability to provide proper education for their ever-growing populations or even already overpopulated regions, many of which have people who have reached the appropriate school-going age. This leads to a series of disruptive impacts on the education systems resulting in a people who are poorly or improperly educated, and thus are not equipped with the necessary skills required for the vast technical, professional and ever modernizing high-skill job markets such as construction, economic and technical professions, teaching occupations and so on, all of which drive economic growth and development. Therefore, we can see that rapid population growth, if left unchecked, may lead to overpopulation scenarios which could have a negative disruptive impact on education and human development, both of which are important factors necessary for economic growth.

In this Review, we elucidate the scope and importance of light pollution and discuss techniques to monitor it. In urban areas, light emissions from sources such as street lights lead to a zenith radiance 40 times larger than that of an unpolluted night sky. Non-urban areas account for over 50\% of the total night-time light observed by satellites, with contributions from sources such as transportation networks and resource extraction. Artificial light can disturb the migratory and reproductive behaviours of animals even at the low illuminances from diffuse skyglow. Additionally, lighting (indoor and outdoor) accounts for 20\% of global electricity consumption and 6\% of CO2 emissions, leading to indirect environmental impacts and a financial cost. However, existing monitoring techniques can only perform a limited number of measurements throughout the night and lack spectral and spatial resolution. Therefore, satellites with improved spectral and spatial resolution are needed to enable time series analysis of light pollution trends throughout the night.}, language = {en} } @article{VegaHoelkerZielinskaDabkowskaetal.2024, author = {Vega, Catherine Perez and H{\"o}lker, Franz and Zielinska-Dabkowska, Karolina M and Jechow, Andreas}, title = {Polarised light pollution on river water surfaces caused by artificial light at night from illuminated bridges and surroundings}, series = {Journal of Limnology}, volume = {83}, journal = {Journal of Limnology}, publisher = {PAGEPress}, doi = {10.4081/jlimnol.2024.2173}, pages = {1 -- 13}, year = {2024}, abstract = {Artificial light at night originating from bridge illumination can cause polarised light pollution when it is reflected at water body surfaces. This alters the optical conditions of a river at night and potentially interferes with natural polarisation signals from, for example, moonlight. Therefore, this type of light pollution could detrimentally change the behaviour of organisms sensitive to polarised light, a navigational cue and signal known to be used e.g. by flying water-seeking insects to detect suitable aquatic habitats to reproduce and lay eggs. So far, polarised light pollution from artificial light at night is understudied. Here, we quantify polarised light pollution at the water's surface near seven illuminated bridges crossing the river Spree in Berlin. Our measurements show for the first time, that nocturnal bridge illumination induces polarised light pollution towards potential flying paths of polarotactic aquatic insects. On average, around 9\% of the water surfaces at the investigated bridges were highly polluted by polarised light, with values ranging between 3 and 12 \% for each bridge. Thus, polarised light pollution from artificial light at night is an emergent pollutant for aquatic systems. Future work on this topic should include more comprehensive measurements, further ecological studies on its impacts and the development of sustainable lighting solutions that can contribute to the protection of riverine nightscapes.}, language = {en} } @article{Jechow2024, author = {Jechow, Andreas}, title = {Let there be Skyglow - light pollution from a large outdoor music festival (Lollapalooza Berlin 2016)}, series = {Scientific Reports}, volume = {14}, journal = {Scientific Reports}, publisher = {Springer Nature}, doi = {10.1038/s41598-024-62448-7}, pages = {1 -- 10}, year = {2024}, abstract = {Live music is often linked to elaborate light shows, particularly at large outdoor music festivals.

Here, the light pollution produced by a major rock festival (Lollapalooza Berlin 2016 with 70,000 visitors per day in an urban park) was investigated with ground-based radiometry and night-time light data. A small night-sky radiometer installed near the main stages and a calibrated digital camera from a nearby observation spot inside of the park were used to quantify changes in night sky brightness and direct light emissions within the park. The impact of the music festival on the urban skyglow was indeed measurable. Zenith luminance increased locally by up to a factor of 8 and illuminance increased by about 50\% at the observation spot within the park. The radiance detected by night-time satellite was also increased during the festival.

The islands can be regarded as liquid inclusions in a two-dimensional fluid in analogy to liquid droplets of the discontinuous phase of an emulsion. The coarsening is effectuated by two processes, predominantly by island coalescence, but to some extend also by Ostwald ripening, whereby large islands grow at the expense of surrounding smaller ones. A peculiarity of this system is that the continuous and the discontinuous phases consist of the same material. We determine the dynamics, analyze the self-similar aging of the island size distribution and discuss characteristic exponents of the mean island growth. Smectic islands on a thin freely suspended smectic film form a quasi two-dimensional emulsion, without a liquid subphase.
