description: FAMILY DUNKLEOSTEIDAE STENSIÖ, 1963   Type genus
 Dunkleosteus Lehman, 1956.
 Diagnosis (modified after Carr & Hlavin, 2010) Pachyosteomorphi in which the interolateral plate contacts the spinal plate laterally; the spinal plate does not bear a spinal pit; the posterior ventrolateral plate bears a small postpectoral lamina; the anterior supragnathal plate in dorsal view forms an open ring with an angle of about 90°; and the parasphenoid bears a pair of posterolateral processes. The clade Dunkleosteidae includes Dunkleosteus as its type genus and all other genera in Dunkleosteoidea Vézina, 1990 more closely related to Dunkleosteus than to Panxiosteus.

description: We discuss the use of parametric phase-diverse phase retrieval as an in-situ high-fidelity wavefront measurement method to characterize and optimize the transmitted wavefront of a high-contrast coronagraphic instrument. We apply our method to correct the transmitted wavefront of the HiCAT (High contrast imager for Complex Aperture Telescopes) coronagraphic testbed. This correction requires a series of calibration steps, which we describe. The correction improves the system wavefront from 16 nm RMS to 3.0 nm RMS.

description: The open problem on whether or not the chirality exists in doublet bands M1 and M4 in light-mass even-even nucleus $^{60}$Ni is studied by adopting the recently developed fully quantal four-$j$ shells triaxial particle rotor model. The corresponding experimental energy spectra, energy differences between doublet bands, and the available $B(M1)/B(E2)$ values are successfully reproduced. The analyses on the basis of the angular momentum components, the azimuthal plots, and the $K$-plots suggest that the chiral modes exist at $I\geq 12\hbar$ in doublet bands M1 and M4.

Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)

description: The properties of zero modes in particle-hole symmetric systems are analyzed in the presence of strong random scattering by a disordered environment. The study is based on the calculation of the time-averaged density distribution on a lattice. In particular, a flat distribution is found for strong random scattering. This result is compared with a decaying distribution for weak random scattering by an analysis of the scattering paths. In the calculation we consider the invariant measure of the average two-particle Green's function, which is related to lattice-covering self-avoiding (LCSA) strings. In particular, strong scattering is associated with LCSA loops, whereas weaker scattering is associated with open LCSA strings. Our results are a generalization of the delocalized state observed at the band center of a one-dimensional tight-binding model with random hopping by Dyson in 1953.

description: High-speed light emitters integrated on silicon chips can enable novel architectures for silicon-based optoelectronics, such as on-chip optical interconnects and silicon photonics. However, conventional light sources based on compound semiconductors face major challenges for their integration with the silicon-based platforms because of the difficulty of their direct growth on a silicon substrate. Here, we report high-brightness, high-speed, ultra-small-size on-chip electroluminescence (EL) emitters based on semiconducting single-walled carbon nanotubes (SWNTs) thin films. The peaks of the EL emission spectra are 0.2-eV red-shifted from the peaks of the absorption and photoluminescence emission spectra, which suggests emission from trions. High-speed responses of ~ 100 ps were experimentally observed from the trion-based EL emitters, which indicates the possibility of several-GHz modulation. The pulsed light generation was also obtained by applying pulse voltage. These high-speed and ultra-small-size EL emitters can enable novel on-chip optoelectronic devices for highly integrated optoelectronics and silicon photonics.

Locally distinguish unextendible product bases by efficiently using entanglement resource

description: Any set of states which cannot be perfectly distinguished by local operations and classical communication (LOCC) alone, can always be locally distinguished using quantum teleportation with enough entanglement resource. However, in quantum information theory, entanglement is a very valuable resource, so it leaves the following open question: how to accomplish this task more efficiently than teleportation, that is, design the local discrimination protocol using less entanglement resource. In this paper, we first present two protocols to locally distinguish a set of unextendible product bases (UPB) in $5\otimes 5$ by using different entanglement resource. Then, we generalize the distinguishing methods for a class of UPB in $d\otimes d$, where $d$ is odd and $d\geqslant 3$. Furthermore, for a class of UPB in $d\otimes d$, where $d$ is even and $d\geqslant 4$, we prove that these states can also be distinguished by LOCC with multiple copies of low-dimensional entanglement resource. These results offer rather general insight into how to use entanglement resource more efficiently, and also reveal the phenomenon of less nonlocality with more entanglement.

description: Durch die Güte des Herrn Hofrats Dr. Brunhuber in Regensburg kam mir ein Stück böhmischer Braunkohle vom Johann-Schacht bei Station Bruch zu, das gleich beim ersten Anblicke meine ganze Aufmerksamkeit erregte; hatte sich mir doch nie Gelegenheit geboten, eine gleiche oder ähnliche fossile Bildung auf Exkursionen und in Sammlungen oder wenigstens in Abbildungen kennen zu lernen. Musste auch der Gedanke, ein Kunstwerk vor sich zu sehen, augenblicklich schwinden, wenn man die schwarze Glanzkohle, in welche das Stück umgewandelt war, erblickte, so konnte doch anfangs der Gedanke, dass man es vielleicht mit in der Aufrollung begriffenen Wedeln eines Farn zu tun habe, Platz greifen. Doch das völlige Fehlen von Spreublättern, wie von Gefässandeutungen, sowie die unverhältnismässige Stärke der vermeintlichen Fiederringel, welche nach der Spitze zu an Dicke zunimmt, neben den un-gemein breiten Flächen der etwa als Stiel zu deutenden Par-tieen Hessen den Gedanken nicht weiter spinnen. Wohl aber mussten jetzt weltliche ähnliche Bildungen, welche in Mittelamerika unter dem Namen Rose de Madeira, in Mexiko unter Rose de Palo bekannt sind, zur Vergleichung herangezogen werden.

Riemann solver with internal reconstruction (RSIR) for compressible single-phase and non-equilibrium two-phase flows

description: A new Riemann solver is built to address numerical resolution of complex flow models. The research direction is closely linked to a variant of the Baer and Nunziato (1986) model developed in Saurel et al. (2017a). This recent model provides a link between the Marble (1963) model for two-phase dilute suspensions and dense mixtures. As in the Marble model, Saurel et al. system is weakly hyperbolic with the same 4 characteristic waves, while the system involves 7 partial differential equations. It poses serious theoretical and practical issues to built simple and accurate flow solver. To overcome related difficulties the Riemann solver of Linde (2002) is revisited. The method is first examined in the simplified context of compressible Euler equations. Physical considerations are introduced in the solver improving robustness and accuracy of the Linde method. With these modifications the flow solver appears as accurate as the HLLC solver of Toro et al. (1994). Second the two-phase flow model is considered. A locally conservative formulation is built and validated removing issues related to non-conservative terms. However, two extra major issues appear from numerical experiments: The solution appears not self-similar and multiple contact waves appear in the dispersed phase. Building HLLC-type or any other solver appears consequently challenging. The modified Linde (2002) method is thus examined for the considered flow model. Some basic properties of the equations are used, such as shock relations of the dispersed phase and jump conditions across the contact wave. Thanks to these ingredients the new Riemann solver with internal reconstruction (RSIR), modification of the Linde method, handles stationary volume fraction discontinuities, presents low dissipation for transport waves and handles shocks and expansion waves accurately. It is validated on various test problems showing method's accuracy and versatility for complex flow models. Its capabilities are illustrated on a difficult two-phase flow instability problem, unresolved before.

description: It is shown how different globally coupled map systems can be analyzed under a common framework by focusing on the dynamics of their respective global coupling functions. We investigate how the functional form of the coupling determines the formation of clusters in a globally coupled map system and the resulting periodicity of the global interaction. The allowed distributions of elements among periodic clusters is also found to depend on the functional form of the coupling. Through the analogy between globally coupled maps and a single driven map, the clustering behavior of the former systems can be characterized. By using this analogy, the dynamics of periodic clusters in systems displaying a constant global coupling are predicted; and for a particular family of coupling functions, it is shown that the stability condition of these clustered states can straightforwardly be derived.

description: Sound event detection (SED) methods typically rely on either strongly labelled data or weakly labelled data. As an alternative, sequentially labelled data (SLD) was proposed. In SLD, the events and the order of events in audio clips are known, without knowing the occurrence time of events. This paper proposes a connectionist temporal classification (CTC) based SED system that uses SLD instead of strongly labelled data, with a novel unsupervised clustering stage. Experiments on 41 classes of sound events show that the proposed two-stage method trained on SLD achieves performance comparable to the previous state-of-the-art SED system trained on strongly labelled data, and is far better than another state-of-the-art SED system trained on weakly labelled data, which indicates the effectiveness of the proposed two-stage method trained on SLD without any onset/offset time of sound events.

description: Each individual investor is different, with different financial goals, different levels of risk tolerance and different personal preferences. From the point of view of investment management, these characteristics are often defined as objectives and constraints. Objectives can be the type of return being sought, while constraints include factors such as time horizon, how liquid the investor is, any personal tax situation and how risk is handled. It's really a balancing act between risk and return with each investor having unique requirements, as well as a unique financial outlook - essentially a constrained utility maximization objective. To analyze how well a customer fits into a particular investor class, one investment house has even designed a structured questionnaire with about two-dozen questions that each has to be answered with values from 1 to 5. The questions range from personal background (age, marital state, number of children, job type, education type, etc.) to what the customer expects from an investment (capital protection, tax shelter, liquid assets, etc.). A fuzzy logic system has been designed for the evaluation of the answers to the above questions. We have investigated the notion of fuzziness with respect to funds allocation.

description: SPT-3G is a polarization-sensitive receiver, installed on the South Pole Telescope, that measures the anisotropy of the cosmic microwave background (CMB) from degree to arcminute scales. The receiver consists of ten 150~mm-diameter detector wafers, containing a total of 16,000 transition-edge sensor (TES) bolometers observing at 95, 150, and 220 GHz. During the 2018-2019 austral summer, one of these detector wafers was replaced by a new wafer fabricated with Al-Mn TESs instead of the Ti/Au design originally deployed for SPT-3G. We present the results of in-lab characterization and on-sky performance of this Al-Mn wafer, including electrical and thermal properties, optical efficiency measurements, and noise-equivalent temperature. In addition, we discuss and account for several calibration-related systematic errors that affect measurements made using frequency-domain multiplexing readout electronics.

description: We consider the scaling behavior of directed percolation and of the pair contact process with a conjugated field. In particular we determine numerically the equation of state and show that both models are characterized by the same universal scaling function. Furthermore we derive the equation of state for the pair contact process within a mean-field approach which again agrees with the mean-field equation of state of the directed percolation universality class.

description: A switch from batch to continuous manufacturing of gallium-68 (68Ga) and 68Ga-labeled pharmaceuticals can be advantageous, as it recycles isotopically-enriched zinc-68 (68Zn), removes pre- and post-irradiation target manipulations, and provides scalability via dose-on-demand production. Herein we report efficient extraction of radiogallium (66,67,68Ga = *Ga) from ZnCl2/HCl solutions in batch and in flow using a membrane-based liquid-liquid separator. From 5.6 M ZnCl2/3 M HCl, a 1/2 (v/v) diisopropyl ether (iPr2O)/trifluorotoluene (TFT) solvent extracts 76.3 ± 1.9% of *Ga and 1.9 ± 1.6% of Zn in flow using a single pass through. From 1 M ZnCl2/6 M HCl, a 1/2 (v/v) n-butyl methyl ether (n-BuOMe)/TFT solvent extracts 95.7 ± 2.0% of *Ga and 0.005 ± 0.003% of Zn in flow. TFT plays a key role in controlling the interfacial tension between the aqueous and the organic phases, ensuring clean membrane-based separation. The process did not extract Cu, Mn, and Co but did extract Fe. Using HGaCl4 and ZnCl2 as the extractable species, the COSMO-RS theory predicts the solvation-driven extraction of Ga and Zn with a mean unsigned error of prediction of 4.0% and 3.4% respectively.

description: A method to calculate the algebraic entropy of a mapping which can be lifted to an isomorphism of a suitable rational surfaces (the space of initial values) are presented. It is shown that the degree of the $n$th iterate of such a mapping is given by its action on the Picard group of the space of initial values. It is also shown that the degree of the $n$th iterate of every Painlevé equation in sakai's list is at most $O(n^2)$ and therefore its algebraic entropy is zero.

description: I. Lumineszenzerscheinungen an einer Varietät der Zinkblende. Bekanntlich unterscheidet man zwei Arten der Strahlung, die Temperaturstrahlung und die Lumineszenzstrahlung. Bei der ersteren ist die Intensität der Strahlung bezw. die Grösse der durch negative Korpuskeln ausgesandten Energie allein abhängig von der Temperatur. Bei der letzteren ist dagegen die durch die Strahlung fortgeführte Energie weit grösser als der Temperatur entspricht. Die Lumineszenzstrahlungen teilt man mit E. Wiedemann1), von dem überhaupt diese Bezeichnung herrührt, in eine Reihe von verschiedenen Gruppen, je nach der Ursache, die dieselben hervorruft. Man spricht von einer Photolumineszenz, wenn die erregende Ursache das Licht ist (Fluoreszenz und Phosphoreszenz), einer Elektrolumineszenz, wenn durch elektrische Entladungen das Leuchten hervorgerufen wird.

description: The viscous coarsening of a phase separated mixture is studied and the effects of the viscosity contrast between the phases are investigated. From an analysis of the microstructure, it appears that for moderate departure from the perfectly symmetric regime the self-similar bicontinuous regime is robust. However, the connectivity of one phase decreases when its volume fraction decreases or when it is becoming less viscous than the complementary phase. Eventually self-similarity breakdown is observed and characterized.

description: Modern psychedelic research and clinical development is at a crucial inflection point, with great potential for the treatment of many mental illnesses demonstrated but significant questions that remain unresolved. Neuroimaging has been pivotal in the modern era of psychedelic research, providing crucial insights into the acute effects of these drugs that revealed translational, clinical potential. Here we review this evidence from functional magnetic resonance imaging, positron emission tomography and magnetoencephalography/electroencephalography studies and describe how these findings inform computational models of both the acute action of psychedelics and their longer-term therapeutic effects. This approach, based on multi-modal neuroimaging, provides a solid evidence base for these therapies as they move forwards, as well as a fuller understanding of the powerful effects of psychedelics on the phenomenology of human consciousness.
Metastable liquid-liquid phase transition in a single-component system with only one crystal phase and no density anomaly

description: We investigate the phase behavior of a single-component system in 3 dimensions with spherically-symmetric, pairwise-additive, soft-core interactions with an attractive well at a long distance, a repulsive soft-core shoulder at an intermediate distance, and a hard-core repulsion at a short distance, similar to potentials used to describe liquid systems such as colloids, protein solutions, or liquid metals. We showed [Nature {\bf 409}, 692 (2001)] that, even with no evidences of the density anomaly, the phase diagram has two first-order fluid-fluid phase transitions, one ending in a gas--low-density liquid (LDL) critical point, and the other in a gas--high-density liquid (HDL) critical point, with a LDL-HDL phase transition at low temperatures. Here we use integral equation calculations to explore the 3-parameter space of the soft-core potential and we perform molecular dynamics simulations in the interesting region of parameters. For the equilibrium phase diagram we analyze the structure of the crystal phase and find that, within the considered range of densities, the structure is independent of the density. Then, we analyze in detail the fluid metastable phases and, by explicit thermodynamic calculation in the supercooled phase, we show the absence of the density anomaly. We suggest that this absence is related to the presence of only one stable crystal structure.

description: Die Grenze zwischen den Ablagerungen der Jura- und Kreideformation ist in der Umgebung von Regensburg ausserordentlich scharf ausgeprägt. Sie macht sich schon orographisch bemerkbar dadurch, dass auf den senkrechten Absturz der Jurafelsen, die den Fuss der die Flusstäler begleitenden Höhen bilden, nunmehr ein schwächer geneigtes Profil folgt, das den leichter zerstörbaren Kreidegesteinen entspricht. Die Juraplatte, in der Regel von ungeschichtetem sogen, plumpen Felsenkalk gebildet, zeigt allenthalben eine vollkommen ebene Oberfläche was man am besten von der Fähre in Sinzing, wo sich ein ausgedehnter Blick auf die das rechte Donauufer bildenden Höhen eröffnet, beobachten kann. (Tafel I, Fig. 1.) Die obere Kante der weissen Kalkfelsen erscheint hier vollkommen ge-radlienigt und wie mit dem Lineal zugeschnitten und auf ihr lagert untnittelbar, schon durch die grüne Farbe lebhaft contrastierend, die Hauptgrünsandbank des Cenoman.

description: The Yang-Mills-Higgs-Bogomolny equations in both 2+1 dimensional Minkowski space-time and 2+1 dimensional anti-de Sitter space-time are known to be integrable and their soliton solutions have already been obtained. In this paper we show that there is a natural relation between the Lax pairs and soliton solutions in these two space-times when the curvature changes from 0 to -1. The change of the asymptotic behaviors of the solitons are also discussed.

Shape-changing Collisions of Coupled Bright Solitons in Birefringent Optical Fibers

description: Wecritically review the recent progress in understanding soliton propagation in birefringent optical fibers.By constructing the most general bright two-soliton solution of the integrable coupled nonlinear Schroedinger equation (Manakov model) we point out that solitons in birefringent fibers can in general change their shape after interaction due to a change in the intensity distribution among the modes even though the total energy is conserved. However, the standard shape-preserving collision (elastic collision) property of the (1+1)-dimensional solitons is recovered when restrictions are imposed on some of the soliton parameters. As a consequence the following further properties can be deduced using this shape-changing collision. (i) The exciting possibility of switching of solitons between orthogonally polarized modes of the birefringent fiber exists. (ii) When additional effects due to periodic rotation of birefringence axes are considered, the shape changing collision can be used as a switch to suppress or to enhance the periodic intensity exchange between the orthogonally polarized modes. (iii) For ultra short optical soliton pulse propagation in non-Kerr media, from the governing equation an integrable system of coupled nonlinear Schroedinger equation with cubic-quintic terms is identified. It admits a nonlocal Poisson bracket structure. (iv) If we take the higher-order terms in the coupled nonlinear Schroedinger equation into account then their effect on the shape-changing collision of solitons, during optical pulse propagation, can be studied by using a direct perturbational approach.
