Providing such services requires to decide how often to instantiate each component, where to place these instances in the network, how to chain them and route traffic through them. \r\nTo overcome limitations of conventional, hardwired heuristics, deep reinforcement learning (DRL) approaches for self-learning network and service management have emerged recently. These model-free DRL approaches are more flexible but typically learn tabula rasa, i.e., disregard existing understanding of networks, services, and their coordination. \r\n\r\nInstead, we propose FutureCoord, a novel model-based AI approach that leverages existing understanding of networks and services for more efficient and effective coordination without time-intensive training. FutureCoord combines Monte Carlo Tree Search with a stochastic traffic model. This allows FutureCoord to estimate the impact of future incoming traffic and effectively optimize long-term effects, taking fluctuating demand and Quality of Service (QoS) requirements into account. Our extensive evaluation based on real-world network topologies, services, and traffic traces indicates that FutureCoord clearly outperforms state-of-the-art model-free and model-based approaches with up to 51% higher flow success ratios.","lang":"eng"}],"file":[{"relation":"main_file","content_type":"application/pdf","file_size":528653,"file_id":"29222","access_level":"open_access","file_name":"author_version.pdf","date_updated":"2022-01-11T08:39:57Z","creator":"stschn","date_created":"2022-01-11T08:39:57Z"}],"ddc":["004"],"keyword":["network management","service management","AI","Monte Carlo Tree Search","model-based","QoS"],"language":[{"iso":"eng"}],"quality_controlled":"1","year":"2022","publisher":"IEEE","date_created":"2022-01-11T08:43:26Z","title":"Use What You Know: Network and Service Coordination Beyond Certainty"},{"oa":"1","date_updated":"2022-02-07T13:32:28Z","author":[{"last_name":"Niehues","full_name":"Niehues, David","id":"36113","first_name":"David"}],"supervisor":[{"first_name":"Tibor","full_name":"Jager, Tibor","id":"64669","last_name":"Jager"},{"full_name":"Lehmann, Anja","last_name":"Lehmann","first_name":"Anja"}],"doi":"10.25926/rdtq-jw45","main_file_link":[{"url":"https://elpub.bib.uni-wuppertal.de/servlets/DerivateServlet/Derivate-14686/de2107.pdf","open_access":"1"}],"has_accepted_license":"1","publication_status":"published","citation":{"apa":"Niehues, D.

While this comes with many advantages such as a more efficient economy, it has also created more and more opportunities for various adversaries to manipulate communication or eavesdrop on it. The Snowden revelations in 2013 further highlighted the seriousness of these threats. To protect the communication of people, companies, and states from such threats, we require cryptography with strong security guarantees.\r\nDifferent applications may require different security properties from cryptographic schemes. For most applications, however, so-called adaptive security is considered a reasonable minimal requirement of security. Cryptographic schemes with adaptive security remain secure in the presence of an adversary that can corrupt communication partners to respond to messages of the adversaries choice, while the adversary may choose the messages based on previously observed interactions.\r\nWhile cryptography is associated the most with encryption, this is only one of many primitives that are essential for the security of digital interactions. This thesis presents novel identity-based encryption (IBE) schemes and verifiable random functions (VRFs) that achieve adaptive security as outlined above. Moreover, the cryptographic schemes presented in this thesis are proven secure in the standard model. That is without making use of idealized models like the random oracle model.","lang":"eng"}],"file":[{"success":1,"relation":"main_file","content_type":"application/pdf","file_size":1542089,"access_level":"closed","file_id":"29764","file_name":"de2107.pdf","date_updated":"2022-02-07T13:26:05Z","creator":"davnie","date_created":"2022-02-07T13:26:05Z"}]},{"author":[{"first_name":"A.K.","full_name":"Verma, A.K.","last_name":"Verma"},{"last_name":"Bopp","full_name":"Bopp, F.","first_name":"F."},{"first_name":"J.J.","full_name":"Finley, J.J.","last_name":"Finley"},{"full_name":"Jonas, B.","last_name":"Jonas","first_name":"B."},{"first_name":"A.","full_name":"Zrenner, A.","last_name":"Zrenner"},{"first_name":"Dirk","last_name":"Reuter","full_name":"Reuter, Dirk","id":"37763"}],"date_created":"2022-05-13T06:11:50Z","publisher":"Elsevier BV","date_updated":"2022-05-13T06:12:40Z","doi":"10.1016/j.jcrysgro.2022.126715","title":"Low Areal Densities of InAs Quantum Dots on GaAs(100) Prepared by Molecular Beam Epitaxy","publication_status":"published","publication_identifier":{"issn":["0022-0248"]},"citation":{"ieee":"A.

However, pushing the concept of the geometric phase toward the acoustic community still faces challenges. In this work, we utilize two acoustic nonlocal metagratings that could support a direct conversion between an acoustic plane wave and a designated vortex mode to obtain the acoustic geometric phase, in which an orbital angular momentum conversion process plays a vital role. In addition, we realize the acoustic geometric phases of different orders by merely varying the orientation angle of the acoustic nonlocal metagratings. Intriguingly, according to our developed theory, we reveal that the reflective acoustic geometric phase, which is twice the transmissive one, can be readily realized by transferring the transmitted configuration to a reflected one. Both the theoretical study and experimental measurements verify the announced transmissive and reflective acoustic geometric phases. Moreover, the reconfigurability and continuous phase modulation that covers the 2π range shown by the acoustic geometric phases provide us with the alternatives in advanced acoustic wavefront control.","lang":"eng"}],"status":"public","_id":"31480","user_id":"30525","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"article_number":"211702","keyword":["Physics and Astronomy (miscellaneous)"],"language":[{"iso":"eng"}]},{"_id":"31541","user_id":"42514","department":[{"_id":"15"},{"_id":"230"}],"article_number":"157401","type":"journal_article","status":"public","date_updated":"2022-05-31T05:47:21Z","author":[{"first_name":"Michal","full_name":"Kobecki, Michal","last_name":"Kobecki"},{"first_name":"Alexey V.","full_name":"Scherbakov, Alexey V.","last_name":"Scherbakov"},{"first_name":"Serhii M.","full_name":"Kukhtaruk, Serhii M.","last_name":"Kukhtaruk"},{"full_name":"Yaremkevich, Dmytro D.","last_name":"Yaremkevich","first_name":"Dmytro D."},{"last_name":"Henksmeier","full_name":"Henksmeier, Tobias","first_name":"Tobias"},{"first_name":"Alexander","full_name":"Trapp, Alexander","last_name":"Trapp"},{"id":"37763","full_name":"Reuter, Dirk","last_name":"Reuter","first_name":"Dirk"},{"first_name":"Vitalyi E.","last_name":"Gusev","full_name":"Gusev, Vitalyi E."},{"first_name":"Andrey V.","full_name":"Akimov, Andrey V.","last_name":"Akimov"},{"first_name":"Manfred","last_name":"Bayer","full_name":"Bayer, Manfred"}],"volume":128,"doi":"10.1103/physrevlett.128.157401","publication_status":"published","publication_identifier":{"issn":["0031-9007","1079-7114"]},"citation":{"apa":"Kobecki, M., Scherbakov, A.

Herein, the nanopillar tops surrounded by a SiNx mask film serve as nanoscale growth areas. The molecular beam epitaxial growth of InAs on such patterned GaAs[Formula: see text]A templates is investigated by means of electron microscopy. It is found that defect-free nanoscale InAs islands grow selectively on the nanopillar tops at a substrate temperature of 425 °C. High-angle annular dark-field scanning transmission electron microscopy imaging reveals that for a growth temperature of 400 °C, the InAs islands show a tendency to form wurtzite phase arms extending along the lateral [Formula: see text] directions from the central zinc blende region of the islands. This is ascribed to a temporary self-catalyzed vapor–liquid–solid growth on [Formula: see text] B facets, which leads to a kinetically induced preference for the nucleation of the wurtzite phase driven by the local, instantaneous V/III ratio, and to a concomitant reduction of surface energy of the nanoscale diameter arms.

Nondispersive bands are observed within the energy gap due to the particular refractive index distribution of the sample. The intrinsic TE-TM splitting and XY splitting of DBR mirrors induce the squeezing of the cavity modes in momentum space, so that the nondispersive bands are tilted and spin-dependent. Our results pave the way to investigate interesting physical phenomena of photonic modes close to or in the nondispersive bands without anisotropic cavity layers.

We present a method to replace the electrical input by supplying the required bias current via the photocurrent of a photodiode situated on the cold stage of the cryostat. Light is guided to the bias photodiode through an optical fiber, which enables a lower thermal conduction and galvanic isolation between room temperature and the cold stage. We show that an off-the-shelf InGaAs–InP photodiode exhibits a responsivity of at least 0.55 A/W at 0.8 K. Using this device to bias an SNSPD, we characterize the count rate dependent on the optical power incident on the photodiode. This configuration of the SNSPD and photodiode shows an expected plateau in the single photon count rate with an optical bias power on the photodiode above 6.8 µW. Furthermore, we compare the same detector under both optical and electrical bias, and show there is no significant changes in performance. This has the advantage of avoiding an electrical input cable, which reduces the latent heat load by a factor of 100 and, in principle, allows for low loss RF current supply at the cold stage.

These analyses rely on locally analyzing the properties, directionality, and magnitude of the second-order nonlinear tensor. However, when inspecting FE DWs with SH microscopy, a manifold of different effects may contribute to the observed signal difference between domains and DWs, i.e., far-field interference, Čerenkov-type phase-matching (CSHG), and changes in the aforementioned local nonlinear optical properties. They all might be present at the same time and, therefore, require careful interpretation and separation. In this work, we demonstrate how the particularly strong Čerenkov-type contrast can selectively be blocked using dark- and bright-field SH microscopy. Based on this approach, we show that other contrast mechanisms emerge that were previously overlayed by CSHG but can now be readily selected through the appropriate experimental geometry. Using the methods presented, we show that the strength of the CSHG contrast compared to the other mechanisms is approximately 22 times higher. This work lays the foundation for the in-depth analysis of FE DW topologies by SH microscopy."}],"publication":"Journal of Applied Physics","title":"Turn all the lights off: Bright- and dark-field second-harmonic microscopy to select contrast mechanisms for ferroelectric domain walls","publisher":"AIP Publishing","date_created":"2023-10-11T08:53:25Z","year":"2022","quality_controlled":"1","issue":"24"}]
