MATERIALS AND METHODS: Data of 50 consecutive patients, who underwent HPB surgery from 04/2018 to 07/2018 were prospectively collected for this study. During surgery, IOUS with a high-resolution ultrasound device using CEUS after bolus injection of 2.4-5 ml Sulphur hexafluoride microbubbles using a 6-9 MHz probe and a share wave and strain elastography was performed by an experienced examiner. Process and time analysis were carried out using mobile phone timer. RESULTS: The IOUS with CEUS and elastography correctly identified 42 malignant tumors and 4 benign lesions. In 3 cases, the examination provided false positive result (identifying 3 benign lesions as malignant) and in 1 case a malignant lesion was incorrectly assessed as benign (sensitivity 97,7\%, specificity 57,1\%, PPV 93,3\% and NPV 80\%). The specific question by the surgeon could be answered successfully in 98\% of the cases. In 76\% of the cases, there was a modification (42\%) or a fundamental change (34\%) of the planned surgical approach due to the information provided by the IOUS. Within the last group, the IOUS had a major impact on therapy outcome. In 7 patients an additional tumor resection was required, in 5 patients the tumor was assessed as inoperable, and in total in 5 patients an intraoperative RFA (4/5) or postoperative RITA (1/5) was required. Regarding procedural input, there was only a slight, but significant difference between the transport and set-up times before the intraoperative use (mean: 14 min 22 s) and the return transport (mean 13 min 6 s), (p = 0,038). The average examination time was 14 minutes, which makes only one third of the overall time demand. CONCLUSION: Combination of IOUS with CEUS and elastography in oncological HPB surgery provides valuable information that affects surgical decision-making. The procedural input of about 45 minutes seems to be a good investment considering the improvement of the surgical procedure and a significant modification of the therapy approach in the majority of the cases.}, language = {en} } @misc{HallSchmidtWaggeetal., author = {Hall, Braeden and Schmidt, Kathleen and Wagge, Jordan and Lewis, Savannah C. and Weissgerber, Sophia C. and Kiunke, Felix and Pfuhl, Gerit and Stieger, Stefan and Tran, Ulrich S. and Barzykowski, Krystian and Bogatyreva, Natalia and Kowal, Marta and Massar, KarlIJn and Pernerstofer, Felizitas and Sorokowski, Piotr and Voracek, Martin and Chartier, Christopher R. and Brandt, Mark J. and Grahe, Jon E. and {\"O}zdoğru, Asil A. and Andreychik, Michael R. and Chen, Sau-Chin and Evans, Thomas R. and Hautekiet, Caro and IJzerman, Hans and Kačm{\´a}r, Pavol and Krafnick, Anthony J. and Musser, Erica D. and Vergauwe, Evie and Werner, Kaitlyn M. and Aczel, Balazs and Arriaga, Patr{\´i}cia and Batres, Carlota and Beaudry, Jennifer L. and Cova, Florian and Ďurbisov{\´a}, Simona and Cramblet Alvarez, Leslie D. and Feldman, Gilad and Godbersen, Hendrik and Gottfried, Jaroslav and Haeffel, Gerald J. and Hartanto, Andree and Isloi, Chris and McFall, Joseph P. and Milyavskaya, Marina and Moreau, David and Nos{\´a}ľov{\´a}, Ester and Papaioannou, Kostas and Ruiz-Fernandez, Susana and Schr{\"o}tter, Jana and Storage, Daniel and Vezirian, Kevin and Volz, Leonhard and Weisberg, Yanna J. and Xiao, Qinyu and Awlia, Dana and Branit, Hannah W. and Dunn, Megan R. and Groyecka-Bernard, Agata and Haneda, Ricky and Kielinska, Julita and Kolle, Caroline and Lubomski, Paweł and Miller, Alexys M. and M{\ae}kel{\ae}, Martin J. and Pantazi, Mytro and Ribeiro, Rafael R. and Ross, Robert M. and Sorokowska, Agnieszka and Aberson, Christopher L. and Vassiliou, Xanthippi Alexi and Baker, Bradley J. and Bognar, Miklos and Cong, Chin Wen and Danvers, Alex F. and Davis, William E. and Dranseika, Vilius and Dumbravă, Andrei and Farmer, Harry and Field, Andy P. and Forscher, Patrick S. and Graton, Aur{\´e}lien and Hajdu, Nandor and Howlett, Peter A. and Kabut, Radosław and Larsen, Emmett M. and Lee, Sean T.

At the same time the methodology sustains the spatial resolution of a 3D model. This goal is reached by reducing the 3D fluid side with its time consuming continuity, momentum, energy and turbulence equations to a simple but precise 1D model. Because of the solid structure staying three dimensional, heat flux direction and spatial resolution have 3D accuracy but short calculation times due to the simple heat diffusion equation to be solved. The 1D model is represented by an automatically generated equation system which is capable of considering transient effects. The energy transfer between 1D fluid model and 3D structure model is realized through a neutral 1D-3D-coupling program and the application of the fluid element specific Nusselt correlations. The following approach is not only applicable for engine development but for any field where fast transient CHT simulations of internal flows are needed. The theretical background and the newly developed approach are presented in this paper. For this purpose an abstract pipe system is used to generate a hydraulic and thermal network. This network is coupled with a 3D structure in order to show the potential velocity benefit and the possible loss in accuray compared to the conventional full 3D modeling approach.}, language = {en} } @misc{KendaKraftTortschanoffetal., author = {Kenda, Andreas and Kraft, Martin and Tortschanoff, Andreas and Scherf, Werner and Sandner, Thilo and Schenk, Harald and Luettjohann, Stephan and Simon, Apolline}, title = {Development, characterization and application of compact spectrometers based on MEMS with in-plane capacitive drives}, series = {Next-generation spectroscopic technologies VII, 5 - 6 May 2014, Baltimore, Maryland, United States}, journal = {Next-generation spectroscopic technologies VII, 5 - 6 May 2014, Baltimore, Maryland, United States}, publisher = {SPIE}, address = {Bellingham, Wash.}, isbn = {978-1-62841-038-9}, pages = {910102-1 -- 910102-10}, language = {en} } @misc{BoenteProcherUrbigetal., author = {B{\"o}nte, Werner and Procher, Vivien D. and Urbig, Diemo and Voracek, Martin}, title = {Digit Ratio (2D:4D) predicts self-reported measures of general competitiveness, but not behavior in economic experiments}, series = {Frontiers in Behavioral Neuroscience}, volume = {11}, journal = {Frontiers in Behavioral Neuroscience}, issn = {1662-5153}, doi = {10.3389/fnbeh.2017.00238}, abstract = {The ratio of index finger length to ring finger length (2D:4D) is considered to be a putative biomarker of prenatal androgen exposure (PAE), with previous research suggesting that 2D:4D is associated with human behaviors, especially sex-typical behaviors. This study empirically examines the relationship between 2D:4D and individual competitiveness, a behavioral trait that is found to be sexually dimorphic. We employ two related, but distinct, measures of competitiveness, namely behavioral measures obtained from economic experiments and psychometric self-reported measures. Our analyses are based on two independent data sets obtained from surveys and economic experiments with 461 visitors of a shopping mall (Study I) and 617 university students (Study II). The correlation between behavior in the economic experiment and digit ratios of both hands is not statistically significant in either study. In contrast, we find a negative and statistically significant relationship between psychometric self-reported measures of competitiveness and right hand digit ratios (R2D:4D) in both studies. This relationship is especially strong for younger people. Hence, this study provides some robust empirical evidence for a negative association between R2D:4D and self-reported competitiveness. We discuss potential reasons why digit ratio may relate differently to behaviors in specific economics experiments and to self-reported general competitiveness.}, language = {en} } @misc{BoehmKueckenHauffeetal., author = {B{\"o}hm, Uwe and K{\"u}cken, Martin and Hauffe, Detlef and Gerstengarbe, F.-W. and Werner, P.

In Case I, we focused on the agricultural yield loss risk for maize in Northeastern Brazil during a drought linked to an El-Ni{\~n}o event. In Case II, the present-day regional climatic conditions in Europe for a 10-year period are simulated. To comprehensively evaluate the model results for both kinds of investigations, we developed a general methodology. On its basis, we elaborated and implemented modules to assess the quality of model results using both advanced visualization techniques and statistical algorithms. Besides univariate approaches for individual near-surface parameters, we used multivariate statistics to investigate multiple near-surface parameters of interest together. For the latter case, we defined generalized quality measures to quantify the model's accuracy. Furthermore, we elaborated a diagnosis tool applicable for atmospheric variables to assess the model's accuracy in representing the physical processes above the surface under various aspects. By means of this evaluation approach, it could be demonstrated in Case Study I that the accuracy of the applied regional climate model resides at the same level as that we found for another regional model and a global model. Excessive precipitation during the rainy season in coastal regions could be identified as a major contribution leading to this result. In Case Study II, we also identified the accuracy of the investigated mean characteristics for near-surface temperature and precipitation to be comparable to another regional model. In this case, an artificial modulation of the used initial and boundary data during preprocessing could be identified as the major source of error in the simulation. Altogether, the achieved results for the presented investigations indicate the potential of our methodology to be applied as a common test bed to different fields of research in regional climate modeling.}, language = {en} } @misc{RoederUrbigStoeckmannetal., author = {R{\"o}der, Martin and Urbig, Diemo and St{\"o}ckmann, Christoph and B{\"o}nte, Werner and Procher, Vivien D.}, title = {There's no fox like an old fox: Dimensions of entrepreneurial orientation and venture closure}, series = {26th Annual Interdisciplinary Conference on Entrepreneurship, Innovation and SMEs, 2023}, journal = {26th Annual Interdisciplinary Conference on Entrepreneurship, Innovation and SMEs, 2023}, abstract = {Only a few scholars examined downsides of EO and suggest it may negatively affect survival. Previous research, which mainly focuses on mature companies, assumes that the relationship between EO and survival is constant. However, because firm characteristics and causal mechanisms change as young venture survive and grow into mature firms, the relationships between EO and survival could also change over time. We extend the EO literature by considering changing EO effects when venture grow into mature firms and by employing a multidimensional view on EO and identify isolating independent mechanisms for the influence of each dimension (i.e. innovativeness, proactiveness and risk-taking) on the survival of young ventures. While the nature of proactiveness on performance is rathe positive, risk-taking and innovativeness increases the variance of firm performance and thus the chances of failure. However, the latter can be separated according to whether the increase in variance occurs at a single point in time (risk-taking) or over time (innovation) and whether the survivors have more money or more innovations. For young firms, innovativeness and risk-taking inhibit survival, while proactiveness promotes it, so the dimensions have divergent effects. As a consequence of the attrition of young ventures, the associations of innovativeness and risk-taking reverse when they grow older. Our empirical analyses are based on panel data of 8,518 young firms.}, language = {en} } @misc{KarnapkeRichterWerner, author = {Karnapke, Reinhardt and Richter, Martin and Werner, Matthias}, title = {Virtualization in robot swarms: past, present, and future}, series = {2024 IEEE 21st Consumer Communications \& Networking Conference (CCNC)}, journal = {2024 IEEE 21st Consumer Communications \& Networking Conference (CCNC)}, publisher = {IEEE}, isbn = {979-8-3503-0457-2}, doi = {10.1109/CCNC51664.2024.10454838}, pages = {1 -- 6}, abstract = {Robot swarms have come a long way since the first mobile sensor/actuator networks.
