This process leads to high costs, extended downtime, and material waste. Flexible brazing tapes, which are composed of alloy powder and an organic binder, offer an alternative to full coating removal for targeted repairs. Despite this, the process of vacuum brazing these tapes may lead to the formation of defects, including pores caused by trapped gases or residual binder, which compromise coating durability and corrosion resistance. This study focuses on the utilization of laser remelting as a method for post-processing nickel- and iron-based mixed alloy brazing tapes, with the aim of improving the integrity of the coating. Surface quality was assessed via microscopy and microhardness testing by systematically varying laser power, scanning speed, and hatch distance. Among the parameters studied, the most suitable laser parameter combination was found to be 350 W laser power, 250 mm/s scanning speed, and a hatch distance of 0.02 mm. These parameters yielded crack- and pore-free coatings with a remelting depth of 160.3 ± 17.2 µm and a microhardness of 701 ± 23 HV1, which is an 85\% increase over as-brazed samples. Wear testing revealed a reduced coefficient of friction, and electrochemical corrosion tests showed lower corrosion current density and enhanced repassivation behavior in remelted coatings. These improvements demonstrate that laser remelting significantly enhances the microstructure, hardness, wear resistance, and corrosion performance of brazed coatings, providing an effective method for localized repair while minimizing material consumption and processing duration.}, language = {en} } @book{SchoeffnerSenne2026, author = {Sch{\"o}ffner, G{\"u}nther and Senne, Petra}, title = {Professionelle Zusammenarbeit von Gesch{\"a}ftsf{\"u}hrung und Betriebsrat.

TNCs with well-known brands started to introduce codes of conduct for their suppliers as early as the 1990s. However, this approach was rarely, if ever, addressed or monitored through international or national law. Ensuring socially responsible supply chains was anchored in the voluntary assumption of responsibilities by private corporate actors. The inadequacies of the business-driven soft law approach to improve working conditions at supplier factories and natural resource collection sites drove a shift toward legal regulation.

However, optimizing the deposition characteristics, such as dimensional accuracy, surface quality, and layer uniformity, remains a key challenge, partly due to the complex dynamics of heat input and melt pool behavior. This study examines the influence of electron beam modulation on these deposition characteristics by systematically varying beam deflection parameters, including frequency and pattern, during the wire-based additive manufacturing of titanium. The effects of beam modulation on wire melting, melt pool stability, layer formation, and overall build geometry were thoroughly evaluated. The results demonstrate that carefully controlled electron beam modulation enables significant improvements in deposition stability, surface finish, and control over geometric features, thereby enhancing process reliability and enabling the production of near-net-shape titanium components. Notably, a parameter set consisting of a circular beam deflection at an oscillation frequency of 500Hz and an overfocus setting of + 40 mA effectively minimized surface ripples and waviness, thereby enhancing process stability and yielding defect-free components.

Drawing on the Conservation of Resources Theory (COR), we investigate how and when servant leadership affects leaders' mental health, viewing its role not only as resource-depleting but also as resource-generating for leaders, depending on the organizational context. Two cross-sectional studies were conducted using leader self-assessments (N = 101; N = 170). Study 1 focused on the relationship between servant leadership, experienced meaningfulness, emotional exhaustion, and flourishing, emphasizing the resource-generating potential of servant leadership. Study 2, examined the moderating effect of the distributive justice climate (DJC) on the link between servant leadership and emotional exhaustion, exploring the possibility of resource depletion under conditions of low organizational fairness. Results. In Study 1, servant leadership was found to mitigate emotional exhaustion by enhancing experienced meaningfulness at work. Moreover, it fostered leaders' flourishing through the same mechanism, suggesting that servant leadership can be a source of leaders' well-being. Study 2 demonstrated that DJC moderates the servant leadership-emotional exhaustion relationship. Specifically, when DJC is low, servant leaders are more susceptible to emotional exhaustion, indicating that unfair organizational climates can exacerbate the resource-depleting aspects of servant leadership. Servant leadership has the potential to both reduce and exacerbate emotional exhaustion in leaders. While it generates psychological resources like experienced meaningfulness, which enhances well-being, its effectiveness is influenced by the organizational context. In unjust environments, servant leadership's emotional demands may lead to resource depletion. These findings are in line with COR and highlight the complex impact of servant leadership on the well-being of leaders.

Second, molecular intersections between HHT and related pathologies call for coordinated, cross-disease programmes rather than isolated efforts. Recent multi-stakeholder gatherings hosted by patient organisations in Germany and elsewhere, such as the Second Scientific Symposium by the German HHT self-help group (Morbus Osler Selbsthilfe e.V.) in May 2025, have shown that when clinicians, basic scientists from different disciplines, and affected families co-design research questions, novel in vitro models can be generated more accurately, and pragmatic clinical trials emerge. Here, we outline actual opportunities for patient-integrated cellular model systems, shared biobanking, and comparative approaches across vascular malformation syndromes.

Phishing simulations via email are a widespread tool used to measure user awareness, especially in workplace settings. However, current studies focusing on large-scale analysis of phishing simulations often have issues: The phishing simulations were conducted using a small sample size (mostly one or two organizations), or while many emails are sent, the analysis focuses only on specific companies. This study analyzes phishing simulations conducted over three years at 36 organizations with over 68 000 delivered emails. We compare different dimensions of the organizations where these simulations were conducted, such as the economic sector and departments. Furthermore, we evaluate various dimensions of phishing simulation campaigns, such as detection difficulty and the scenario under which the simulation occurs. Our findings indicate significant disparities in the results, such as the industry sector in which the company operates. Moreover, we find substantial differences between the success rates of varying scenarios used for phishing emails.}, language = {en} } @inproceedings{BoettgerHosseiniUtzetal.2025, author = {B{\"o}ttger, Christian and Hosseini, Henry and Utz, Christine and Demir, Nurullah and H{\"o}rnemann, Jan and Wressnegger, Christian and Hupperich, Thomas and Pohlmann, Norbert and Große-Kampmann, Matteo and Urban, Tobias}, title = {Privacy from 5 PM to 6 AM: Tracking and Transparency Mechanisms in the HbbTV Ecosystem}, series = {2025 55th Annual IEEE/IFIP International Conference on Dependable Systems and Networks (DSN). 23-26 June 2025, Naples, Italy.

However, its bidirectional transmission functionality raises privacy concerns, as it introduces new tracking methods for TV channels. While previous studies focused on security issues or user awareness of HbbTV privacy challenges, a detailed examination of the tracking and transparency mechanisms of the HbbTV ecosystem is still missing. This study fills this gap by extensively analyzing these features within the European HbbTV ecosystem, and in particular within German-language TV channels. We monitored more than 350 TV channels for over 400 hours, evaluating 1) prevalent HbbTV tracking methods, 2) consent notice prevalence and user interactions, and 3) privacy policy disclosures. Our findings indicate that the HbbTV tracking system operates independently of the Web, consent notices exploit system constraints to influence users, and privacy policies often do not align with actual data practices.}, language = {en} } @article{Wienbracke2025, author = {Wienbracke, Mike}, title = {Keine Landeskompetenz f{\"u}r Anschlusszusage f{\"u}r Postdocs de lege lata ; BVerfG, Beschluss vom 25.6.2025 - 1 BvR 368/22 ; [Anmerkungen]}, series = {Gesellschafts- und Wirtschaftsrecht (GWR)}, journal = {Gesellschafts- und Wirtschaftsrecht (GWR)}, number = {20}, publisher = {Beck}, address = {M{\"u}nchen}, issn = {1868-1816}, pages = {350 -- 350}, year = {2025}, language = {de} } @article{Wienbracke2025, author = {Wienbracke, Mike}, title = {Kommunale Verpackungssteuern sind verfassungsgem{\"a}ß!}, series = {NWB Steuer- und Wirtschaftsrecht}, journal = {NWB Steuer- und Wirtschaftsrecht}, number = {13}, publisher = {NWB}, address = {Herne}, issn = {0028-3460}, pages = {849 -- 855}, year = {2025}, language = {de} } @article{Wienbracke2025, author = {Wienbracke, Mike}, title = {Steuerschulden als Grund f{\"u}r die Versagung oder Entziehung verwaltungsrechtlicher Erlaubnisse}, series = {NWB Steuer- und Wirtschaftsrecht}, journal = {NWB Steuer- und Wirtschaftsrecht}, number = {11}, publisher = {NWB}, address = {Herne}, issn = {0028-3460}, pages = {721 -- 726}, year = {2025}, language = {de} } @book{Wienbracke2025, author = {Wienbracke, Mike}, title = {Allgemeines Verwaltungsrecht}, publisher = {C.

How higher fungi respond to dsRNA is not known. We demonstrate that Magnaporthe oryzae (Mo), a globally significant crop pathogen, internalizes dsRNA across a broad size range of 21 to about 3000 bp. Incubation of fungal conidia with 10 ng/μL dsRNA, regardless of size or sequence, induced aberrant germ tube elongation, revealing a strong sequence-unspecific effect of dsRNA in this fungus. Accordingly, the synthetic dsRNA analogue poly(I:C) and dsRNA of various sizes and sequences elicited canonical fungal stress pathways, including nuclear accumulation of the stress marker mitogen-activated protein kinase Hog1p and production of ROS. Leaf application of dsRNA to the cereal model species Brachypodium distachyon suppressed the progression of leaf blast disease. Notably, the sequence-unspecific effect of dsRNA depends on higher doses, while pure sequence-specific effects were observed at low concentrations of dsRNA ( < 0.03 ng/μL). The protective effects of dsRNA were further enhanced by maintaining a gap of at least seven days between dsRNA application and inoculation, and by stabilising the dsRNA in alginate-chitosan nanoparticles. Overall, our study opens up additional possibilities for the development and use of dsRNA pesticides in agriculture.}, language = {en} } @article{Wienbracke2025, author = {Wienbracke, Mike}, title = {EuGH: Fremdbesitzverbot f{\"u}r Rechtsanwaltsgesellschaften ist unionsrechtskonform : Urteil vom 19.12.2024 - C-295/23 (BayAGH) ; [Anmerkungen]}, series = {Gesellschafts- und Wirtschaftsrecht (GWR)}, journal = {Gesellschafts- und Wirtschaftsrecht (GWR)}, number = {7}, publisher = {Beck}, address = {M{\"u}nchen}, issn = {1868-1816}, pages = {113 -- 113}, year = {2025}, language = {de} }
