Several major centers of massive spread of invasive plant pests have been found in urban dendroflora of this region. The degree of damage of seven most wide-spread aboriginal tree species was found to range from 21.4±1.1 to 85.4±1.8\%. In particular, the integrity of the native communities of sycamore (Platanus spp.), willow (Salix spp.), poplar (Populus spp.) and elm (Ulmus spp.) is highly endangered. Our taxonomic analysis of the most dangerous tree pests of the region has revealed them as neobiontic xylophilous insects such as Cossus cossus L. (Order: Lepidoptera L.) Monochamus urussovi Fisch., Monochamus sutor L., Acanthocinus aedelis L. and {\~N}etonia aureate L. (Order: Coleoptera L.). We relate the origin of this threatening trend with the import of industrial wood in the mid 90’s of the last century that was associated with high degree of the constructional work in the region. Because of the absence of efficient natural predators of the pest species, the application of microbiological methods of the pest control and limitation is suggested.}, language = {en} } @article{TurdumamatovBeldaHeuermann2024, author = {Turdumamatov, Samat and Belda, Aljoscha and Heuermann, Holger}, title = {Shaping a decoupled atmospheric pressure microwave plasma with antenna structures, Maxwell's equations, and boundary conditions}, series = {IEEE Transactions on Plasma Science}, journal = {IEEE Transactions on Plasma Science}, number = {Early Access}, publisher = {IEEE}, issn = {0093-3813 (Print)}, doi = {10.1109/TPS.2024.3383589}, pages = {1 -- 9}, year = {2024}, abstract = {This article addresses the need for an innovative technique in plasma shaping, utilizing antenna structures, Maxwell's laws, and boundary conditions within a shielded environment. The motivation lies in exploring a novel approach to efficiently generate high-energy density plasma with potential applications across various fields. Implemented in an E01 circular cavity resonator, the proposed method involves the use of an impedance and field matching device with a coaxial connector and a specially optimized monopole antenna. This setup feeds a low-loss cavity resonator, resulting in a high-energy density air plasma with a surface temperature exceeding 3500 o C, achieved with a minimal power input of 80 W. The argon plasma, resembling the shape of a simple monopole antenna with modeled complex dielectric values, offers a more energy-efficient alternative compared to traditional, power-intensive plasma shaping methods. Simulations using a commercial electromagnetic (EM) solver validate the design's effectiveness, while experimental validation underscores the method's feasibility and practical implementation. Analyzing various parameters in an argon atmosphere, including hot S -parameters and plasma beam images, the results demonstrate the successful application of this technique, suggesting its potential in coating, furnace technology, fusion, and spectroscopy applications.}, language = {en} } @article{TurekKeusgenPoghossianetal.2008, author = {Turek, M. and Keusgen, M. and Poghossian, Arshak and Mulchandani, A. and Wang, J. and Sch{\"o}ning, Michael Josef}, title = {Enzyme-modified electrolyte-insulator-semiconductor sensors}, series = {Journal of Contemporary Physics. 43 (2008), H. 2}, journal = {Journal of Contemporary Physics. 43 (2008), H. 2}, isbn = {1934-9378}, pages = {82 -- 85}, year = {2008}, language = {en} } @article{TurekHeidenGuoetal.2010, author = {Turek, Monik and Heiden, Wolfgang and Guo, Sharon and Riesen, Alfred and Schubert, J{\"u}rgen and Zander, Willi and Kr{\"u}ger, Peter and Keusgen, Michael and Sch{\"o}ning, Michael Josef}, title = {Simultaneous detection of cyanide and heavy metals for environmental analysis by means of µISEs}, series = {Physica Status Solidi (A). 207 (2010), H. 4}, journal = {Physica Status Solidi (A). 207 (2010), H. 4}, isbn = {1862-6300}, pages = {817 -- 823}, year = {2010}, language = {en} } @article{TurekKettererClassenetal.2007, author = {Turek, Monika and Ketterer, Lothar and Claßen, Melanie and Berndt, Heinz and Elbers, Gereon and Kr{\"u}ger, Peter and Keusgen, Michael and Sch{\"o}ning, Michael Josef}, title = {Development and Electrochemical Investigations of an EIS-(Electrolyte-Insulator-Semiconductor) based Biosensor for Cyanide Detection}, series = {Sensors}, volume = {7}, journal = {Sensors}, number = {8}, isbn = {1424-8220}, pages = {1415 -- 1426}, year = {2007}, language = {en} } @article{TurlybekulyPogrebnjakSukhodubetal.2019, author = {Turlybekuly, Amanzhol and Pogrebnjak, Alexander and Sukhodub, L.

Research shows that training environments that adapt to users' preferences and performance can promote more effective learning. However, the observed results can hardly be traced back to specific adaptive measures but the whole new training approach. This study analyzes the effects of a combined point and leveling VR-based gamification system on assembly training targeting specific training outcomes and users' motivations. The Gamified-VR-Group with 26 subjects received the gamified training, and the Non-Gamified-VR-Group with 27 subjects received the alternative without gamified elements. Both groups conducted their VR training at least three times before assembling the actual structure. The study found that a level system that gradually increases the difficulty and error probability in VR can significantly lower real-world error rates, self-corrections, and support usages. According to our study, a high error occurrence at the highest training level reduced the Gamified-VR-Group's feeling of competence compared to the Non-Gamified-VR-Group, but at the same time also led to lower error probabilities in real-life. It is concluded that a level system with a variable task difficulty should be combined with carefully balanced positive and negative feedback messages. This way, better learning results, and an improved self-evaluation can be achieved while not causing significant impacts on the participants' feeling of competence.}, language = {en} } @article{UlmerBraunChengetal.2023, author = {Ulmer, Jessica and Braun, Sebastian and Cheng, Chi-Tsun and Dowey, Steve and Wollert, J{\"o}rg}, title = {A human factors-aware assistance system in manufacturing based on gamification and hardware modularisation}, series = {International Journal of Production Research}, journal = {International Journal of Production Research}, publisher = {Taylor \& Francis}, issn = {0020-7543 (Print)}, doi = {10.1080/00207543.2023.2166140}, year = {2023}, abstract = {Assistance systems have been widely adopted in the manufacturing sector to facilitate various processes and tasks in production environments.

Methods In vivo unenhanced MR was performed in 8 healthy volunteers on a 7T whole-body MR system. After B0 shimming the following sequences were obtained: 1) 2D and 3D spoiled gradient-echo sequences (FLASH, VIBE), 2) T1-weighted 2D in and opposed phase 3) True-FISP imaging and 4) a T2-weighted turbo spin echo (TSE) sequence. Visual evaluation of the overall image quality was performed by two radiologists. Results Renal MRI at 7T was feasible in all eight subjects. Best image quality was found using T1-weighted gradient echo MRI, providing high anatomical details and excellent conspicuity of the non-enhanced vasculature. With successful shimming, B1 signal voids could be effectively reduced and/or shifted out of the region of interest in most sequence types. However, T2-weighted TSE imaging remained challenging and strongly impaired because of signal heterogeneities in three volunteers. Conclusion The results demonstrate the feasibility and diagnostic potential of dedicated 7T renal imaging. Further optimisation of imaging sequences and dedicated RF coil concepts are expected to improve the acquisition quality and ultimately provide high clinical diagnostic value.}, language = {en} } @article{UndenBeckerBongaertsetal.1995, author = {Unden, G. and Becker, S. and Bongaerts, Johannes and Holighaus, G. and Schirawski, J. and Six, S.}, title = {O2-sensing and O2-dependent gene regulation in facultatively anaerobic bacteria}, series = {Archives of microbiology}, volume = {Vol. 164}, journal = {Archives of microbiology}, number = {Iss. 2}, issn = {1432-072X (E-Journal); 0003-9276 (Print); 0302-8933 (Print)}, pages = {81 -- 90}, year = {1995}, language = {en} } @article{UndenBeckerBongaertsetal.1994, author = {Unden, G. and Becker, S. and Bongaerts, Johannes and Schirawski, J. and Six, S.}, title = {Oxygen regulated gene expression in facultatively anaerobic bacteria}, series = {Antonie van Leeuwenhoek}, volume = {Vol. 66}, journal = {Antonie van Leeuwenhoek}, number = {Iss. 1-3}, issn = {0003-6072 (Print) ; 1572-9699 (online)}, pages = {3 -- 22}, year = {1994}, language = {en} } @article{UndenBongaerts1997, author = {Unden, Gottfried and Bongaerts, Johannes}, title = {Alternative respiratory pathways of Escherichia coli: energetics and transcriptional regulation in response to electron acceptors}, series = {Biochimica et biophysica acta (BBA) - Bioenergetics}, volume = {Vol. 1320}, journal = {Biochimica et biophysica acta (BBA) - Bioenergetics}, number = {Iss. 3}, issn = {1879-2650 (E-Journal); 0005-2728 (Print)}, pages = {217 -- 234}, year = {1997}, language = {en} } @article{UngermannsAheCariusetal.1997, author = {Ungermanns, C. and Ahe, M. v. d. and Carius, Reinhard and F{\"o}rster, Arnold}, title = {Optimization of III/V binary growth with RHEED in MOMBE / C.
