The observations are assumed to be generated under the semi-parametric random censorship model (SRCM), that is, a random censorship model where the conditional expectation of the censoring indicator given the observation belongs to a parametric family. Under this setup a semi-parametric estimator of the survival function was introduced by the author. If the parametric model assumption is correct, it is known that the estimated functional which is based on this semi-parametric estimator is asymptotically at least as efficient as the corresponding one which rests on the nonparametric Kaplan-Meier estimator. In this paper we show that the estimated functional which is based on this semi-parametric estimator is asymptotically efficient with respect to the class of all regular estimators under this semi-parametric model.}, language = {en} } @article{Dikta2017, author = {Dikta, Gerhard}, title = {Semi-parametric random censorship models}, series = {From Statistics to Mathematical Finance : Festschrift in Honour of Winfried Stute}, journal = {From Statistics to Mathematical Finance : Festschrift in Honour of Winfried Stute}, publisher = {Springer}, address = {Berlin}, isbn = {978-3-319-50986-0}, doi = {10.1007/978-3-319-50986-0_3}, pages = {43 -- 56}, year = {2017}, language = {en} } @article{DigelZhubanovaNojimaetal.2004, author = {Digel, Ilya and Zhubanova, Azhar A. and Nojima, H. and Artmann, Gerhard}, title = {The use of bactericidal effects of cluster ions generated by plasma in medical biotechnology}, series = {Biotechnologija : teorija i praktika (2004)}, journal = {Biotechnologija : teorija i praktika (2004)}, isbn = {1028-9399}, pages = {46 -- 52}, year = {2004}, language = {en} } @article{DigelZerlinTemizArtmannetal.2007, author = {Digel, Ilya and Zerlin, Kay and Temiz Artmann, Ayseg{\"u}l and Engels, S.}, title = {Protein dynamics in thermosensation}, series = {Regenerative medicine. 2 (2007), H. 5}, journal = {Regenerative medicine. 2 (2007), H. 5}, isbn = {1746-0751}, pages = {533 -- 533}, year = {2007}, language = {en} } @article{DigelWehlitzKayseretal.2018, author = {Digel, Ilya and Wehlitz, V. and Kayser, Peter and Figiel-Lange, A. and Bassam, Rasha and Rundstedt, F. von}, title = {Suspension depletion approach for exemption of infected Solanum jasminoides cells from pospiviroids}, series = {Plant Pathology}, volume = {67}, journal = {Plant Pathology}, number = {2}, publisher = {Wiley}, address = {Oxford}, issn = {1365-3059}, doi = {10.1111/ppa.12750}, pages = {358 -- 365}, year = {2018}, abstract = {Despite numerous studies, viroid elimination from infected plants remains a very challenging task. This study introduces for the first time a novel 'suspension depletion' approach for exemption of Solanum jasminoides plants from viroids. The proposed method implies initial establishment of suspension cultures of the infected plant cells. The suspended cells were then physically treated (mild thermotherapy, 33 °C), which presumably delayed the replication of the viroid. The viroid concentration in the treated biomass was monitored weekly using pospiviroid-specific PCR. After 10-12 weeks of continuous treatment, a sufficient decrease in viroid concentration was observed such that the infection became undetectable by PCR. The treated single cells then gave rise to microcolonies on a solid culture medium and the obtained viroid-negative clones were further promoted to regenerate into viroid-free plants. Three years of accumulated experimental data suggests feasibility, broad applicability, and good efficacy of the proposed approach.}, language = {en} } @article{DigelTrzewikDemircietal.2004, author = {Digel, Ilya and Trzewik, J{\"u}rgen and Demirci, Taylan and Temiz Artmann, Ayseg{\"u}l}, title = {Response of fibroblasts to cyclic mechanical stress : a proteome approach / Digel, I. ; Trzewik, J. ; Demirci, T. ; Temiz Artmann, A. ; Artmann, G.

We overviewed the physical effects that occurred during brushing and tried to address the question of whether ultrasonic toothbrushes effectively reduced the microbial burden by increasing the hydrodynamic forces. The results of published studies show that electric toothbrushes, which combine ultrasonic and sonic (or acoustic and mechanic) actions, may have the most promising effect on good oral health. Existing ultrasonic/sonic toothbrush models do not significantly differ regarding the removal of dental biofilm and the reduction of gingival inflammation compared with other electrically powered toothbrushes, whereas the manual toothbrushes show a lower effectiveness.}, language = {en} } @article{DigelKayserArtmann2008, author = {Digel, Ilya and Kayser, Peter and Artmann, Gerhard}, title = {Molecular processes in biological thermosensation}, series = {Journal of Biophysics. 2008 (2008)}, journal = {Journal of Biophysics. 2008 (2008)}, isbn = {1687-8000}, pages = {1 -- 9}, year = {2008}, language = {en} } @article{DigelDemirciTemizArtmannetal.2004, author = {Digel, Ilya and Demirci, Taylan and Temiz Artmann, Ayseg{\"u}l and Nishikawa, K.}, title = {Free Radical Nature of the Bactericidal Effect of Plasma-Generated Cluster Ions (PCIs)}, series = {Biomedizinische Technik. 49 (2004), H.

The culture medium was composed of different initial concentrations of glucose or sucrose dissolved in 0.4\% extract of plain green tea. Parameters of the culture media (titratable acidity, substrate conversion degree etc.) were monitored daily for 20 days of cultivation. The BC pellicles produced on different carbon sources were characterized in terms of biomass yield, crystallinity and morphology by field emission scanning electron microscopy (FE-SEM), atomic force microscopy and X-ray diffraction. Our results showed that Medusomyces gisevii had higher BC yields in media with sugar concentrations close to 10 g L-1 after a 18-20 days incubation period. Glucose in general lead to a higher BC yield (173 g L-1) compared to sucrose (163.5 g L-1). The BC crystallinity degree and surface roughness were higher in the samples synthetized from sucrose. Obtained FE-SEM micrographs show that the BC pellicles synthesized in the sucrose media contained densely packed tangles of cellulose fibrils whereas the BC produced in the glucose media displayed rather linear geometry of the BC fibrils without noticeable aggregates.}, language = {en} }
