    Including radiative transfer processes within the urban canopy layer into microscale urban climate models (UCMs) is essential to obtain realistic model results. These processes include the interaction of buildings and ...
  • Alexandrou, Theodosis (Dordrecht [u.a.] : Springer Science + Business Media B.V, 2022)
    Let f: S′⟶ S be a cyclic branched covering of smooth projective surfaces over C whose branch locus Δ ⊂ S is a smooth ample divisor. Pick a very ample complete linear system | H| on S, such that the polarized surface (S, | ...
  • Nguyen, Chuong Thanh (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2022)
    Metamaterials are artificial composites with micro-structures that are systematically designed such that the macroscopic behavior can accommodate particular functionalities or exhibit extraordinary properties, which are ...
  • Bahl, Henning; Fuchs, Elina; Heinemeyer, Sven; Katzy, Judith; Menen, Marco; Peters, Krisztian; Saimpert, Matthias; Weiglein, Georg (Berlin ; Heidelberg : Springer, 2022)
    CP violation in the Higgs couplings to fermions is an intriguing, but not yet extensively explored possibility. We use inclusive and differential LHC Higgs boson measurements to fit the CP structure of the Higgs Yukawa ...
  • Hantzko, Lukas; Kumar, Kaushlendra; Costa, Gabriel Picanço (Berlin ; Heidelberg : Springer, 2022)
    We revisit a newfound construction of rational electromagnetic knots based on the conformal correspondence between Minkowski space and a finite S3-cylinder. We present here a more direct approach for this conformal ...
  • Hulek, Klaus; Liese, Carsten ([Erscheinungsort nicht ermittelbar] : [Verlag nicht ermittelbar], 2022)
    In this paper we study the Mori fan of the Dolgachev–Nikulin–Voisin family in degree 2 as well as the associated secondary fan. The main result is an enumeration of all maximal dimensional cones of the two fans. © by the ...

    The Andean snowpack is an important source of water for many communities. As other snow-covered regions around the world, the Andes are sensitive to black carbon (BC) deposition from fossil fuel and biomass combustion. BC ...
  • Guo, Hongwei; Zhuang, Xiaoying; Chen, Pengwan; Alajlan, Naif; Rabczuk, Timon (London : Springer, 2022)
    In this work, we present a deep collocation method (DCM) for three-dimensional potential problems in non-homogeneous media. This approach utilizes a physics-informed neural network with material transfer learning reducing ...
  • Guo, Hongwei; Zhuang, Xiaoying; Chen, Pengwan; Alajlan, Naif; Rabczuk, Timon (London : Springer, 2022)
    We present a stochastic deep collocation method (DCM) based on neural architecture search (NAS) and transfer learning for heterogeneous porous media. We first carry out a sensitivity analysis to determine the key ...
  • Chakraborty, Ayan; Anitescu, Cosmin; Zhuang, Xiaoying; Rabczuk, Timon (London : Springer, 2022)
    In machine learning, if the training data is independently and identically distributed as the test data then a trained model can make an accurate predictions for new samples of data. Conventional machine learning has a ...
  • Cuntz, Michael (New York, NY : Springer, 2021)
    We introduce a greedy algorithm optimizing arrangements of lines with respect to a property. We apply this algorithm to the case of simpliciality: it recovers all known simplicial arrangements of lines in a very short time ...
  • Diehl, Patrick; Lipton, Robert; Wick, Thomas; Tyagi, Mayank (Berlin ; Heidelberg : Springer, 2022)
    Computational modeling of the initiation and propagation of complex fracture is central to the discipline of engineering fracture mechanics. This review focuses on two promising approaches: phase-field (PF) and peridynamic ...
  • Maier, Roland; Morgenstern, Philipp; Takacs, Thomas (Amsterdam : Elsevier Science, 2022)
    We present an adaptive refinement algorithm for T-splines on unstructured 2D meshes. While for structured 2D meshes, one can refine elements alternatingly in horizontal and vertical direction, such an approach cannot be ...
  • Gimperlein, Heiko; Özdemir, Ceyhun; Stephan, Ernst P. (Berlin : De Gruyter, 2022)
    This article considers a coupled finite and boundary element method for an interface problem for the acoustic wave equation. Well-posedness, a priori and a posteriori error estimates are discussed for a symmetric space-time ...
  • Cedzich, C.; Geib, T.; Grünbaum, F.A.; Velázquez, L.; Werner, A.H.; Werner, R.F. (Berlin ; Heidelberg : Springer, 2021)
    This paper uncovers and exploits a link between a central object in harmonic analysis, the so-called Schur functions, and the very hot topic of symmetry protected topological phases of quantum matter. This connection is ...
  • Bauer, Wolfram; Rodriguez Rodriguez, Miguel Angel (Cham (ZG) : Springer International Publishing AG, 2022)
    We present a survey and new results on the construction and Gelfand theory of commutative Toeplitz algebras over the standard weighted Bergman and Hardy spaces over the unit ball in Cn. As an application we discuss ...

    The precision of matter-wave sensors benefits from interrogating large-particle-number atomic ensembles at high cycle rates. Quantum-degenerate gases with their low effective temperatures allow for constraining systematic ...

    Organoids represent the cellular composition of natural tissue. So called colonoids, organoids derived from colon tissue, are a good model for understanding regeneration. However, next to the cellular composition, the ...
  • Maronga, Björn; Li, Dan (Dordrecht [u.a.] : Springer Science + Business Media B.V, 2021)
    We revisit the longstanding problem of grid sensitivity, i.e., the lack of grid convergence in large-eddy simulations (LES) of the stable boundary layer. We use a comprehensive set of LES of the well-known Global Energy ...
  • Laurençot, Philippe; Nik, Katerina; Walker, Christoph (Berlin ; Heidelberg : Springer, 2021)
    A model for a MEMS device, consisting of a fixed bottom plate and an elastic plate, is studied. It was derived in a previous work as a reinforced limit when the thickness of the insulating layer covering the bottom plate ...
