We have experimentally and systematically investigated the binding energy of biexcitons, highlighting the importance of the uniformity of all excitonic lines, rather than concentrating solely on the uniformity of the neutral exciton as a typical figure of merit, as it is normally done in the literature. We present optical signatures of GaAs QDs within a range of ∼250 meV with a remarkable uniformity within each individual sample, the ability to excite the biexciton state resonantly, and a systematic study of the fine-structure splitting (FSS) values—features important for polarization entangled photon emission.

In liquid environments, viscoelastic spectroscopy and high-frequency rheology are possible, even on layers with a thickness in the monolayer range. For particulate samples, the contact stiffness can be derived. Because the stress at the contact is large, the force is not always proportional to the displacement. Nonlinear effects are observed, leading to a dependence of the resonance frequency and the resonance bandwidth on the amplitude of oscillation. Partial slip, in particular, can be studied in detail.

Previous related literature has provided profound knowledge in cases when the system is augmented with no-flux/no-flux/no-slip boundary conditions for the density of cells, the chemical concentration and the fluid velocity field, respectively; in particular, available qualitative results strongly indicate that only trivial solution behavior can be expected on large time scales. In line with refined modeling approaches to oxygen evolution near fluid-air interfaces, this study now focuses on situations involving a fixed chemoattractant concentration on the boundary. Despite an apparent loss of mathematically favorable energy structures thereby induced, by means of an alternative variational approach a basic theory of global existence is developed in a natural framework of weak solvability. Beyond this, some additional qualitative information on the large time behavior of these solutions is derived by identifying a certain global relaxation property. Specifically, a second result asserts, within a suitable topological setting, the existence of a bounded set which eventually absorbs each individual of the obtained trajectories, and the diameter of which is bounded only by the physically relevant quantities of total population size and prescribed boundary concentration of the chemical signal. </jats:p>"}],"publication":"Mathematical Models and Methods in Applied Sciences","issue":"01"},{"type":"journal_article","date_created":"2025-12-18T19:23:28Z","abstract":[{"text":"<jats:p>We consider the no-flux initial-boundary value problem for the cross-diffusive evolution system:<jats:disp-formula><jats:alternatives><jats:graphic xmlns:xlink=\"http://www.w3.org/1999/xlink\" mime-subtype=\"png\" mimetype=\"image\" xlink:href=\"S0956792521000279_eqnU1.png\"/><jats:tex-math>\r\n\\begin{eqnarray*}        \\left\\{ \\begin{array}{ll}        u_t = u_{xx} - \\chi \\big(\\frac{u}{v} \\partial_x v \\big)_x - uv +B_1(x,t),        \\qquad &amp; x\\in \\Omega, \\ t&gt;0, \\\\[1mm]        v_t = v_{xx} +uv - v + B_2(x,t),        \\qquad &amp; x\\in \\Omega, \\ t&gt;0,        \\end{array} \\right.  \\end{eqnarray*}\r\n</jats:tex-math></jats:alternatives></jats:disp-formula>which was introduced by Short <jats:italic>et al.</jats:italic> in [40] with <jats:inline-formula><jats:alternatives><jats:inline-graphic xmlns:xlink=\"http://www.w3.org/1999/xlink\" mime-subtype=\"png\" xlink:href=\"S0956792521000279_inline1.png\"/><jats:tex-math>\r\n$\\chi=2$\r\n</jats:tex-math></jats:alternatives></jats:inline-formula> to describe the dynamics of urban crime.</jats:p><jats:p>In bounded intervals <jats:inline-formula><jats:alternatives><jats:inline-graphic xmlns:xlink=\"http://www.w3.org/1999/xlink\" mime-subtype=\"png\" xlink:href=\"S0956792521000279_inline2.png\"/><jats:tex-math>\r\n$\\Omega\\subset\\mathbb{R}$\r\n</jats:tex-math></jats:alternatives></jats:inline-formula> and with prescribed suitably regular non-negative functions <jats:inline-formula><jats:alternatives><jats:inline-graphic xmlns:xlink=\"http://www.w3.org/1999/xlink\" mime-subtype=\"png\" xlink:href=\"S0956792521000279_inline3.png\"/><jats:tex-math>\r\n$B_1$\r\n</jats:tex-math></jats:alternatives></jats:inline-formula> and <jats:inline-formula><jats:alternatives><jats:inline-graphic xmlns:xlink=\"http://www.w3.org/1999/xlink\" mime-subtype=\"png\" xlink:href=\"S0956792521000279_inline4.png\"/><jats:tex-math>\r\n$B_2$\r\n</jats:tex-math></jats:alternatives></jats:inline-formula>, we first prove the existence of global classical solutions for any choice of <jats:inline-formula><jats:alternatives><jats:inline-graphic xmlns:xlink=\"http://www.w3.org/1999/xlink\" mime-subtype=\"png\" xlink:href=\"S0956792521000279_inline5.png\"/><jats:tex-math>\r\n$\\chi&gt;0$\r\n</jats:tex-math></jats:alternatives></jats:inline-formula> and all reasonably regular non-negative initial data.</jats:p><jats:p>We next address the issue of determining the qualitative behaviour of solutions under appropriate assumptions on the asymptotic properties of <jats:inline-formula><jats:alternatives><jats:inline-graphic xmlns:xlink=\"http://www.w3.org/1999/xlink\" mime-subtype=\"png\" xlink:href=\"S0956792521000279_inline6.png\"/><jats:tex-math>\r\n$B_1$\r\n</jats:tex-math></jats:alternatives></jats:inline-formula> and <jats:inline-formula><jats:alternatives><jats:inline-graphic xmlns:xlink=\"http://www.w3.org/1999/xlink\" mime-subtype=\"png\" xlink:href=\"S0956792521000279_inline7.png\"/><jats:tex-math>\r\n$B_2$\r\n</jats:tex-math></jats:alternatives></jats:inline-formula>.

Dabei ist vor allem die Wahl der Materialparameter der verwendeten Materialien wichtig für ein realitätsnahes Simulationsergebnis. Bei Schallwandlern werden häufig Piezokeramiken als aktive Elemente genutzt, welche sich durch eine Verkopplung mechanischer und elektrischer Eigenschaften auszeichnen. Zur Bestimmung ihrer Materialparameter stellt der IEEE Standard on Piezoelectricity ein standardisiertes Verfahren dar. Dazu sind fünf Impedanzmessungen an vier unterschiedlich gefertigten Probekörpergeometrien notwendig. Da an jedem einzelnen Probekörper nur eine Untermenge aller notwendigen Materialparameter bestimmt werden kann, werden diese dann zu einem kompletten Materialparametersatz zusammengefügt. Aufgrund der unterschiedlichen Prozessbedingungen, bei denen die jeweiligen Probekörper hergestellt werden, ist dieser Materialparametersatz jedoch inkonsistent und kann nie das Verhalten einer einzelnen Probe beschreiben. Daher wird in der vorliegenden Arbeit ein Messverfahren entwickelt, mit dem es möglich ist, alle relevanten Materialparameter unter besonderer Berücksichtigung von Dämpfung an einem einzelnen Probekörper allein durch Impedanzmessungen zu bestimmen. Als Probekörper wird dazu eine in der Anwendung häufig verwendete Scheibengeometrie verwendet. Um eine hinreichend hohe Sensitivität auf alle Materialparameter zu gewährleisten, wird diese mit einer optimierten Elektrodentopologie gefertigt. Da in diesem Fall keine analytische Betrachtung mehr möglich ist, wird das Messverfahren durch einen inversen Ansatz realisiert.","lang":"ger"},{"text":"Design processes of ultrasonic transducers become increasingly simulation-driven due to rising computational capabilities. Therewithin, the choice of the material parameters for modelling the materials used is particularly important for a realistic simulation result. Piezoceramics, which couple mechanic and electrical properties, are often used as active elements in ultrasonic transducers.The IEEE Standard on Piezoelectricity is a standardised procedure for determining these parameters that requires five impedance measurements on four piezocermics of different geometry. Since only a subset of all necessary material parameters can be determined for each individual specimen, these are then combined to form a complete set of material parameters. Due to different processing conditions for each specimen, this set of material parameters is inconsistent and cannot describe the behaviour of a single specimen appropriately. Therefore, in the present thesis, a method is developed with enables the determination of all relevant material parameters including damping on a single piezocermic by means of electrical impedance measurements alone. A piezoelectric ceramic with disc-shaped geometry, which is frequently used in applications, is used as a specimen.In order to ensure a sufficiently high sensitivity to all material parameters, it is manufactured with an optimised electrode topology. Because in this case analytical solutions, which relate the measurement quantities to the material parameters, do not exist, the measurement method is implemented using an inverse approach.","lang":"eng"}]},{"user_id":"11829","volume":88,"page":"294 - 302","_id":"21341","status":"public","quality_controlled":"1","project":[{"_id":"90","name":"Ein modellbasiertes Messverfahren zur Charakterisierung der frequenzabhängigen Materialeigenschaften von Piezokeramiken unter Verwendung eines einzelnen Probekörperindividuums"},{"name":"FOR 5208: Modellbasierte Bestimmung nichtlinearer Eigenschaften von Piezokeramiken für Leistungsschallanwendungen (NEPTUN)","_id":"245"}],"citation":{"bibtex":"@article{Feldmann_Schulze_Claes_Jurgelucks_Meihost_Walther_Henning_2021, title={Modelling damping in piezoceramics: A comparative study}, volume={88}, DOI={<a href=\"https://doi.org/10.1515/teme-2020-0096\">10.1515/teme-2020-0096</a>}, number={5}, journal={tm - Technisches Messen}, author={Feldmann, Nadine and Schulze, Veronika and Claes, Leander and Jurgelucks, Benjamin and Meihost, Lars and Walther, Andrea and Henning, Bernd}, year={2021}, pages={294–302} }","ama":"Feldmann N, Schulze V, Claes L, et al.

A newly developed procedure can be used to identify the behaviour of piezoceramic discs over a wide frequency range using a single specimen via fitting simulated and measured impedances by optimising the underlying material parameters. Since there is no generally accepted damping model for piezoelectric ceramics, several mechanical damping models are examined for the material identification. Three models have been chosen and their ability to replicate the measured impedances is evaluated. On the one hand, the common Rayleigh model is considered as a reference. On the other hand, a Zener model and a model using complex constants are extended to model the transversely isotropic material. As the Rayleigh model is only valid for a limited frequency range, it fails to model the broadband behaviour of the material. The model using complex constants leads to the best fit over a wide frequency range while at the same time only adding three additional parameters for modelling damping. Thus, damping can be assumed approximately frequency-independent in piezoceramics."}],"publication":"tm - Technisches Messen","issue":"5"},{"page":"237-238","_id":"22012","language":[{"iso":"eng"}],"doi":"10.5162/SMSI2021/A10.1","user_id":"11829","title":"Optimised Multi-Electrode Topology for Piezoelectric Material Characterisation","status":"public","year":"2021","conference":{"location":"Nürnberg","name":"Sensor and Measurement Science International"},"publication_identifier":{"unknown":["978-3-9819376-4-0"]},"author":[{"last_name":"Claes","first_name":"Leander","orcid":"0000-0002-4393-268X","full_name":"Claes, Leander","id":"11829"},{"id":"23082","full_name":"Feldmann, Nadine","last_name":"Feldmann","first_name":"Nadine"},{"full_name":"Jurgelucks, Benjamin","last_name":"Jurgelucks","first_name":"Benjamin"},{"full_name":"Schulze, Veronika","last_name":"Schulze","first_name":"Veronika"},{"full_name":"Schmidt, Stephan","first_name":"Stephan","last_name":"Schmidt"},{"last_name":"Walther","first_name":"Andrea","full_name":"Walther, Andrea"},{"first_name":"Bernd","last_name":"Henning","full_name":"Henning, Bernd","id":"213"}],"date_updated":"2026-01-05T07:54:28Z","date_created":"2021-05-06T16:25:42Z","type":"conference","department":[{"_id":"49"}],"citation":{"ieee":"L.
