  text: 'In this work we address disentanglement of style and content in speech signals.
    We propose a fully convolutional variational autoencoder employing two encoders:
    a content encoder and a style encoder. To foster disentanglement, we propose adversarial
    contrastive predictive coding. This new disentanglement method does neither need
    parallel data nor any supervision. We show that the proposed technique is capable
    of separating speaker and content traits into the two different representations
    and show competitive speaker-content disentanglement performance compared to other
    unsupervised approaches. We further demonstrate an increased robustness of the
    content representation against a train-test mismatch compared to spectral features,
    when used for phone recognition.'

  text: "The first order optimality conditions of optimal control problems (OCPs)
    can\r\nbe regarded as boundary value problems for Hamiltonian systems. Variational
    or\r\nsymplectic discretisation methods are classically known for their excellent\r\nlong
    term behaviour. As boundary value problems are posed on intervals of\r\nfixed,
    moderate length, it is not immediately clear whether methods can profit\r\nfrom
    structure preservation in this context. When parameters are present,\r\nsolutions
    can undergo bifurcations, for instance, two solutions can merge and\r\nannihilate
    one another as parameters are varied. We will show that generic\r\nbifurcations
    of an OCP are preserved under discretisation when the OCP is\r\neither directly
    discretised to a discrete OCP (direct method) or translated\r\ninto a Hamiltonian
    boundary value problem using first order necessary\r\nconditions of optimality
    which is then solved using a symplectic integrator\r\n(indirect method). Moreover,
    certain bifurcations break when a non-symplectic\r\nscheme is used. The general
    phenomenon is illustrated on the example of a cut\r\nlocus of an ellipsoid."

  text: We propose a reachability approach for infinite and finite horizon multi-objective
    optimization problems for low-thrust spacecraft trajectory design. The main advantage
    of the proposed method is that the Pareto front can be efficiently constructed
    from the zero level set of the solution to a Hamilton-Jacobi-Bellman equation.
    We demonstrate the proposed method by applying it to a low-thrust spacecraft trajectory
    design problem. By deriving the analytic expression for the Hamiltonian and the
    optimal control policy, we are able to efficiently compute the backward reachable
    set and reconstruct the optimal trajectories. Furthermore, we show that any reconstructed
    trajectory will be guaranteed to be weakly Pareto optimal. The proposed method
    can be used as a benchmark for future research of applying reachability analysis
    to low-thrust spacecraft trajectory design.

  text: Nonlinear and quantum optical devices based on periodically-poled thin film
    lithium niobate (PP-TFLN) have gained considerable interest lately, due to their
    significantly improved performance as compared to their bulk counterparts. Nevertheless,
    performance parameters such as conversion efficiency, minimum pump power, and
    spectral bandwidth strongly depend on the quality of the domain structure in these
    PP-TFLN samples, e.g., their homogeneity and duty cycle, as well as on the overlap
    and penetration depth of domains with the waveguide mode. Hence, in order to propose
    improved fabrication protocols, a profound quality control of domain structures
    is needed that allows quantifying and thoroughly analyzing these parameters. In
    this paper, we propose to combine a set of nanometer-to-micrometer-scale imaging
    techniques, i.e., piezoresponse force microscopy (PFM), second-harmonic generation
    (SHG), and Raman spectroscopy (RS), to access the relevant and crucial sample
    properties through cross-correlating these methods. Based on our findings, we
    designate SHG to be the best-suited standard imaging technique for this purpose,
    in particular when investigating the domain poling process in x-cut TFLNs. While
    PFM is excellently recommended for near-surface high-resolution imaging, RS provides
    thorough insights into stress and/or defect distributions, as associated with
    these domain structures. In this context, our work here indicates unexpectedly
    large signs for internal fields occurring in x-cut PP-TFLNs that are substantially
    larger as compared to previous observations in bulk LN.

  text: In the last two decades, variably doped strontium barium niobate (SBN) has
    attracted a lot of scientific interest mainly due to its specific non-linear optical
    response. Comparably, the parental compound, i.e., undoped SBN, appears to be
    less studied so far. Here, two different cuts of single-crystalline nominally
    pure strontium barium niobate in the composition Sr0.61Ba0.39Nb2O6 (SBN61) are
    comprehensively studied and analyzed with regard to their photoconductive responses.
    We present conductance measurements under systematically varied illumination conditions
    along either the polar z-axis or perpendicular to it (x-cut). Apart from a pronounced
    photoconductance (PC) already under daylight and a large effect upon super-bandgap
    illumination in general, we observe (i) distinct spectral features when sweeping
    the excitation wavelength over the sub-bandgap region as then discussed in the
    context of deep and shallow trap states, (ii) extremely slow long-term relaxation
    for both light-on and light-off transients in the range of hours and days, (iii)
    a critical dependence of the photoresponse on the pre-illumination history of
    the sample, and (iv) a current–voltage hysteresis depending on both the illumination
    and the electrical-measurement conditions in a complex manner.

  text: Exceptionally electron-rich, nearly trigonal-planar tricyanidometalate anions
    [Fe(CN)3]7− and [Ru(CN)3]7− were stabilized in LiSr3[Fe(CN)3] and AE3.5[M(CN)3]
    (AE=Sr, Ba; M=Fe, Ru). They are the first examples of group 8 elements with the
    oxidation state of −IV. Microcrystalline powders were obtained by a solid-state
    route, single crystals from alkali metal flux. While LiSr3[Fe(CN)3] crystallizes
    in P63/m, the polar space group P63 with three-fold cell volume for AE3.5[M(CN)3]
    is confirmed by second harmonic generation. X-ray diffraction, IR and Raman spectroscopy
    reveal longer C−N distances (124–128 pm) and much lower stretching frequencies
    (1484–1634 cm−1) than in classical cyanidometalates. Weak C−N bonds in combination
    with strong M−C π-bonding is a scheme also known for carbonylmetalates. Instead
    of the formal notation [Fe−IV(CN−)3]7−, quantum chemical calculations reveal non-innocent
    intermediate-valent CN1.67− ligands and a closed-shell d10 configuration for Fe,
    that is, Fe2−.
