An ecosystem metabolome analysis revealed that skyglow increased the production of algal-derived metabolites, which appeared to stimulate heterotrophic activities as well. Furthermore, we found evidence that skyglow decreased the number of bacteria-bacteria interactions. Effects of skyglow were more pronounced at night, suggesting that responses to skyglow can occur on short time scales.

Our study uses a multiorbital Hubbard model, incorporating all Ni 3⁢𝑑 and O 2⁢𝑝 states. We analyze the superconducting pairing mechanism of La3⁢Ni2⁢O7 within the random phase approximation and find a transition between 𝑑-wave and sign-changing 𝑠-wave pairing states as a function of pressure and interaction parameters, which is driven by spin fluctuations with different wave vectors. These spin fluctuations with incommensurate wave vectors cooperatively stabilize a superconducting order parameter with 𝑑𝑥2-𝑦2 symmetry for realistic model parameters.

Thus, bio-optical modeling of inland waters requires higher ground-truthing efforts. Large-scale ground-based sensor networks that are robust, self-sufficient, non-maintenance-intensive and low-cost could assist this otherwise labor-intensive task. Furthermore, most existing sensor systems are rather expensive, precluding their employability.

In Georgia, cervical cancer ranks as the fifth most common cancer among women, with approximately 330 new cases and 200 deaths reported annually. Despite the availability of effective HPV vaccines, national vaccination coverage remains low. This study aimed to evaluate HPV vaccination coverage, analyze cervical cancer incidence trends, and model the potential impact of increased vaccination uptake on cancer prevention outcomes in Georgia. Study design A retrospective observational study was conducted using national health registry data and modeling projections to assess the burden of cervical cancer and estimate the effect of scaled vaccination coverage. Methods National health databases were used to analyze HPV vaccination rates and cervical cancer incidence. Descriptive statistics, chi-square tests, and linear regression were applied to identify trends and disparities. Additionally, a dynamic transmission model was developed to simulate the 10-year impact of increasing HPV vaccination coverage on cervical cancer incidence. Results The crude cervical cancer incidence rate was 15.7 per 100,000 women, with an age-standardized rate of 10.6 per 100,000. In 2022, only 38 \% of eligible girls aged 13-18 received the first HPV vaccine dose, and 26 \% completed the second dose. Regional disparities in vaccination and screening were noted, and overall screening coverage declined to 13,890 women screened in 2022. Modeling showed that increasing vaccine coverage to 60 \% could reduce cervical cancer incidence by 50 \% (preventing ∼163 cases); coverage of 80 \% and 90 \% could reduce incidence by 70 \% and 85 \%, preventing 228 and 276 cases, respectively. Conclusion Low HPV vaccination uptake in Georgia (38 \% first dose and 26 \% dull coverage) and declining screening limit cervical cancer prevention. Modeling shows that increasing vaccination coverage to 60-90 \% could prevent 163-276 cases over the next decade. Strengthening vaccination and screening strategies is essential to move forward elimination.}, language = {en} } @article{KloppTrittelStannarius2024, author = {Klopp, Christoph and Trittel, Torsten and Stannarius, Ralf}, title = {Coarsening of quasi two-dimensional emulsions formed by islands in free-standing smectic films}, series = {ChemPhysChem}, volume = {25}, journal = {ChemPhysChem}, number = {12}, publisher = {Wiley}, doi = {10.1002/cphc.202400166}, pages = {1 -- 12}, year = {2024}, abstract = {We study the coarsening behavior of assemblies of islands on smectic A freely suspended films in ISS microgravity experiments.

To assess and mitigate these impacts, it is crucial that measurements of night sky quality are reliable and comparable across sites and instruments. However, the lack of standardised night sky brightness metrology and the use of a wide variety of measurement instruments with varying spectral responsivity and field-specific measurement units hinder meaningful comparison. We collected night sky spectra from 44 nights at dark locations (existing and proposed dark sky parks). Based on this observational dataset, we created a larger random set of spectra. These data served to fit conversion parameters for a wide variety of units. We demonstrate that RGB cameras, when used as multichannel measuring devices, enable the retrieval of measurements that facilitate conversions between different units. Furthermore, even airglow can be quantified from a given measurement, enabling the determination of oxygen and sodium emission line contributions. Since this contribution is not negligible, quantitative measurements of its magnitude are crucial for accurately assessing light pollution at dark-sky sites. Using our spectral measurement database, we constructed the most probable transformation from the cameras' R, G, and B channel 𝑑𝑠𝑢 values to other units, such as the astronomical Bessel V band magnitudes.

Structured in five modular phases, from self-reflection and knowledge activation to collaborative prototyping and peer evaluation, the workshop offers a hands-on, gamified learning experience centred on real-world sustainability challenges. Learners create user-centred paper-based prototypes for digital products using tactile materials, persona-driven scenarios and knowledge of sustainable product characteristics gained in the workshop. Outcome measurement is supported through pre- and post-workshop surveys, peer voting templates, and paper-based prototype artefacts, enabling rich insight into behavioural intentions and learning gains. The paper discusses the educational value and sustainability relevance of the workshop engaging young people in critically reflecting on the environmental, economic, and social consequences of digitalization.

Although many important common and rare genetic factors causing or contributing to these epilepsies have been identified in the past decades, many features of the genetic architecture are still insufficiently understood. This study integrates genome-wide association study (GWAS) data from the International League Against Epilepsy Consortium on Complex Epilepsies with transcriptome-wide association studies to identify genes whose genetically regulated expression levels are associated with epilepsy. Methods To achieve this, we used multiple computational approaches, including MAGMA, a tool for gene analysis of GWAS data, and its derivatives E-MAGMA and H-MAGMA, to improve gene mapping accuracy by utilizing tissue-specific expression and chromatin interaction data. Furthermore, we developed ME-MAGMA to incorporate methylation quantitative trait loci data, providing insights into epigenetic factors. Results We identified a total of 897 false discovery rate-corrected (<.05) candidates. These include voltage-gated calcium channels, voltage-gated potassium channels, and other genes such as NPRL2, CACNB2, and KCNT1 associated with epilepsy pathogenesis that act as key players in neuronal communication and signaling in the brain. Significance In this study, we propose new candidate genes to expand the dataset of potential epilepsy-causing genes. Further research on these genes may enhance our understanding of the complex regulatory mechanisms underlying GGE and other types of epilepsy, potentially revealing targets for therapeutic intervention.}, language = {en} } @article{OeppertHartzWehneretal.2021, author = {Oeppert, Luise and Hartz, Tobias and Wehner, Kathrin and Schrader, Thomas and Meier, Jens}, title = {FHIR-Datenmodell zur {\"U}bermittlung von Tumordaten zwischen Krebsregistern und IQTIG}, series = {GMS Medizinische Informatik, Biometrie und Epidemiologie}, volume = {17}, journal = {GMS Medizinische Informatik, Biometrie und Epidemiologie}, number = {Iss 4}, publisher = {German Medical Science GMS Publishing House}, doi = {10.3205/mibe000231}, year = {2021}, language = {de} } @article{OseevLucklumZubtsovetal.2017, author = {Oseev, Aleksandr and Lucklum, Ralf and Zubtsov, Mikhail and Schmidt, Marc-Peter and Mukhin, Nikolay V. and Hirsch, Soeren}, title = {SAW-Based Phononic Crystal Microfluidic Sensor—Microscale Realization of Velocimetry Approaches for Integrated Analytical Platform Applications}, series = {Sensors}, volume = {17}, journal = {Sensors}, number = {10}, doi = {10.3390/s17102187}, pages = {2187}, year = {2017}, language = {en} } @article{PfeifferDilipSuryawanshietal.2021, author = {Pfeiffer, Thomas and Dilip, Khadse Himanshu and Suryawanshi, Raunak and Kishnamurthy, Gnana Swaroop and T{\´e}llez, Batcheva Dom{\´i}nguez and Creutzburg, Reiner and Hartmann, Michael}, title = {Airflow visualization and air purifier positioning optimization in potentially COVID-19 contaminated classrooms}, series = {Electronic Imaging}, journal = {Electronic Imaging}, publisher = {Society for Imaging Science and Technology}, address = {Springfield, VA}, issn = {2470-1173}, doi = {10.2352/ISSN.2470-1173.2021.3.MOBMU-039}, pages = {39-1 -- 39-15}, year = {2021}, language = {en} } @article{PilgermannBocklischCreutzburg2020, author = {Pilgermann, Michael and Bocklisch, Thomas and Creutzburg, Reiner}, title = {Conception and implementation of a course for professional training and education in the field of IoT and smart home security}, series = {Electronic Imaging}, journal = {Electronic Imaging}, publisher = {Society for Imaging Science and Technology}, issn = {2470-1173}, doi = {10.2352/ISSN.2470-1173.2020.3.MOBMU-277}, pages = {277-1 -- 277-8}, year = {2020}, language = {en} } @article{PilgermannWerthCreutzburg2020, author = {Pilgermann, Michael and Werth, S{\"o}ren and Creutzburg, Reiner}, title = {Towards sector specific security operation}, series = {Electronic Imaging}, journal = {Electronic Imaging}, publisher = {Society for Imaging Science and Technology}, address = {Springfield, VA}, issn = {2470-1173}, doi = {10.2352/ISSN.2470-1173.2020.3.MOBMU-254}, pages = {254-1 -- 254-10}, year = {2020}, language = {en} } @article{PreethamSataStannariusPuzyrev2025, author = {Preetham Sata, Sai and Stannarius, Ralf and Puzyrev, Dmitry}, title = {Machine learning for prediction of dynamical clustering in granular gases}, series = {EPJ Web of Conferences}, volume = {340}, journal = {EPJ Web of Conferences}, editor = {Alam, M. and Das, S.L. and Bose, M. and Murthy, T.G. and Chikkadi, V. and Singh, A. and Luding, S.}, publisher = {EDP Sciences}, doi = {10.1051/epjconf/202534012012}, year = {2025}, abstract = {Continuously excited dense granular gases in microgravity can develop spatial inhomogeneities of the particle distribution.

We perform Discrete Element Method (DEM) simulations for frictional spheres in a cuboid container and apply statistical criteria to the packing fraction profiles. Machine learning (ML) methods are used to study the dependence of the gas-cluster transition on system parameters. It is a promising alternative to predict the state of the system without the need for the time-consuming DEM simulations.

Sixty-one patients were recruited, with 35 completing the study. The intervention included six games focusing on physical and cognitive training. Outcome measures were motor function, cognitive assessments, quality of life, and depression. Results showed significant improvements in dynamic balance (p = .013) but no significant changes in other measures. The findings suggest that serious games are feasible and can improve motor functions like balance. However, short intervention periods may limit their impact on cognitive function and quality of life.
