Die {\"u}bliche Vorgehensweise in der wissenschaftlichen Literatur wird um zwei Aspekte erweitert: Erstens werden zus{\"a}tzlich zu einzelnen Variablen sogenannte Faktoren ber{\"u}cksichtigt, die vorab mittels einer Hauptkomponentenanalyse aus einem großen Datensatz extrahiert werden. Zweitens wird die Analyse nicht ex-ante auf einen theoriekonsistenten Variablensatz restringiert, sondern alle potentiell bedeutsamen Variablen werden in die Analyse mit einbezogen und mit Hilfe einer Stepwise-Forward-Prozedur selektiert. Die Ergebnisse zeigen, dass diese Erweiterungen bzw. Modifikationen die Prognoseperformance der {\"u}blichen Probit-Modelle erheblich verbessern. Die Analyse dokumentiert den dominanten Einfluss des Auslands auf die deutsche Konjunkturentwicklung. Dar{\"u}ber hinaus zeigen sich Anzeichen von Instabilit{\"a}ten des Probit-Modells in den letzten f{\"u}nf Jahren, gleichwohl der durch die Finanzmarktkrise bedingte Konjunktureinbruch schon ab Mai 2007 im Prognosemodell erkennbar war. Zudem signalisiert das Modell schon seit Januar/Februar 2009, dass der durch die Finanzmarktkrise bedingte Konjunktureinbruch im Verlauf des Jahres 2009 beendet sein wird.}, language = {de} } @article{SievertOetterAubrevilleetal.2021, author = {Sievert, Matti and Oetter, Nicolai and Aubreville, Marc and Stelzle, Florian and Maier, Andreas and Eckstein, Markus and Mantsopoulos, Konstantinos and Gostian, Antoniu-Oreste and M{\"u}ller, Sarina K. and Koch, Michael and Agaimy, Abbas and Iro, Heinrich and Goncalves, Miguel}, title = {Feasibility of intraoperative assessment of safe surgical margins during laryngectomy with confocal laser endomicroscopy}, volume = {48}, journal = {Auris Nasus Larynx}, subtitle = {a pilot study}, number = {4}, publisher = {Elsevier Science}, address = {Amsterdam}, issn = {1879-1476}, doi = {https://doi.org/10.1016/j.anl.2021.01.005}, pages = {764 -- 769}, year = {2021}, language = {en} } @article{SievertAubrevilleGostianetal.2022, author = {Sievert, Matti and Aubreville, Marc and Gostian, Antoniu-Oreste and Mantsopoulos, Konstantinos and Koch, Michael and M{\"u}ller, Sarina K. and Eckstein, Markus and Rupp, Robin and Stelzle, Florian and Oetter, Nicolai and Maier, Andreas and Iro, Heinrich and Goncalves, Miguel}, title = {Validity of tissue homogeneity in confocal laser endomicroscopy on the diagnosis of laryngeal and hypopharyngeal squamous cell carcinoma}, volume = {279}, journal = {European Archives of Oto-Rhino-Laryngology and Head \& Neck}, number = {8}, publisher = {Springer Nature}, address = {Cham}, issn = {1434-4726}, doi = {https://doi.org/10.1007/s00405-022-07304-y}, pages = {4147 -- 4156}, year = {2022}, abstract = {Purpose Confocal laser endomicroscopy (CLE) allows imaging of the laryngeal mucosa in a thousand-fold magnification. This study analyzes differences in tissue homogeneity between healthy mucosa and squamous cell carcinoma (SCC) via CLE. Materials and methods We included five SCC patients with planned total laryngectomy in this study between October 2020 and February 2021. We captured CLE scans of the tumor and healthy mucosa. Analysis of image homogeneity to diagnose SCC was performed by measuring the signal intensity in four regions of interest (ROI) in each frame in a total of 60 sequences. Each sequence was assigned to the corresponding histological pattern, derived from hematoxylin and eosin staining. In addition, we recorded the subjective evaluation of seven investigators regarding tissue homogeneity. Results Out of 3600 images, 1620 (45\%) correlated with benign mucosa and 1980 (55\%) with SCC. ROIs of benign mucosa and SCC had a mean and standard deviation (SD) of signal intensity of, respectively, 232.1 ± 3.34 and 467.3 ± 9.72 (P < 0.001). The mean SD between the four different ROIs was 39.1 ± 1.03 for benign and 101.5 ± 2.6 for SCC frames (P < 0.001). In addition, homogeneity yielded a sensitivity and specificity of 81.8\% and 86.2\%, respectively, regarding the investigator-dependent analysis. Conclusions SCC shows a significant tissue inhomogeneity in comparison to the healthy epithelium. The results support this feature's importance in identifying malignant mucosa areas during CLE examination. However, the examiner-dependent evaluation emphasizes that homogeneity is a sub-criterion that must be considered in a broad context.}, language = {en} } @inproceedings{HeldSteinhauserKamannetal.2019, author = {Held, Patrick and Steinhauser, Dagmar and Kamann, Alexander and Koch, Andreas and Brandmeier, Thomas and Schwarz, Ulrich}, title = {Micro-Doppler extraction of bicycle pedaling movements using automotive radar}, booktitle = {2019 IEEE Intelligent Vehicles Symposium (IV)}, publisher = {IEEE}, address = {Piscataway}, isbn = {978-1-7281-0560-4}, doi = {https://doi.org/10.1109/IVS.2019.8813828}, pages = {744 -- 749}, year = {2019}, language = {en} }
