Hippodonta radiata

description: Hippodonta radiata A. Pavlov, Levkov, D.M. Williams & Edlund, sp. nov. (Figs 291–307)
 Type:— TANZANIA. Lake Tanganyika, tangled in trawl from 8 m depth, ¼ mile offshore between Kjiyi and Bangwe, 4 February 1953, collector R. Ross. (holotype: slide BM! 72160; isotype: slide MKNDC! 005850/A).
Frustules rectangular in girdle view, somewhat constricted in the middle. Valves of larger specimens lanceolate, rhombic-lanceolate, and elliptic-lanceolate in smaller specimens. Valve ends not protracted, broadly cuneate, acutely rounded in larger specimens and broadly rounded in smaller specimens. Valve length 9.0–30.0 µm, width 3.9–5.9 µm. Axial area narrow-linear throughout. Central area forming well-defined fascia, panduriform or less frequently rectangular in shape. Terminal area distinguishable in LM in most specimens, moderately large, semi-circular or triangular in shape. Raphe linear to weakly curved, filiform. Central raphe endings weakly pronounced, with simple circle-shaped or small teardrop-shaped and closely spaced central pores. Terminal pores of raphe rarely discernible in LM, simple linear or small circle-shaped. Striae coarse, moderately to strongly radiate at middle, becoming parallel or weakly convergent towards valve ends. Striae rarely observed to be nearly parallel at middle of valve. Striae pattern throughout valve length also observable on valve mantle in girdle view (Fig. 307). Striae evenly spaced throughout, 10–12 in 10 µm. Interstriae of lower or equal width to striae. Lineolae composing striae densely spaced within a stria and not discernible in LM.
 Distribution:— Hippodonta radiata has so far only been observed from Lake Tanganyika, East Africa. In the type material it is very frequent.
 Observations:—With regard to the valve outline as well as the shape of the central area, H. radiata is most closely similar to H. abunda (Figs 102–137) from Lake Ohrid, H. microcostulata (Figs 482–519) from Lake Baikal and H. geocollegarum Lange-Bert., Metzeltin & Witkowski (1996: 255, 256, figs 4: 1–5) from freshwater deposits of the Arkona Basin, Baltic Sea. The striae of H. radiata are coarser, more pronounced and broader than the striae in H. abunda and H. microcostulata. Additionally the central area of the latter two taxa is narrow and rectangular in shape, while in H. radiata the central area is wider and panduriform. The lineolae in H. geocollegarum are clearly discernible in LM view, compared to the densely spaced and not discernible lineolae in H. radiata.

REMARKS
According to Lamarck (1816) Asterias exigua came from American seas and was the smallest known species of asteroid. As far as size is concerned, he is almost correct. Yet A. exigua does not occur in the Atlantic but in the south of Africa and Australia as well as in Tasmania. Indeed the type specimens of A. exigua were collected in South Africa by Péron and Lesueur in 1804 (Fig. 15B). Individuals of a most likely similar species had been obtained early in 1803 by the same collectors in SE Australia (King George Sound, Albany). The latter were identified Asterina calcar var. quinqueangula by Lamarck, who added on a label that they should be considered juvenile individuals (“ specimen junius ”) (Fig. 15 C-F). Comparing the type specimens of the two Lamarckian species (and to the drawings of Bruguière [1791] to which Lamarck refered, Figure 15A), it is highly likely they are conspecific.
Due to incorrect information (types of Asterias exigua presumed loss), Dartnall (1971) designated a neotype for the species. The latter originated from False Bay (South Africa) and is in the Tasmanian Museum, Hobart (ref. TM H508).

description: The talk focusses on the efforts of journals in economics and business studies in fostering research integrity. We report the findings of an empirical study in which a sample of 346 journals in economics and business studies was examined. One aim of our study was to determine whether these journals support reproducible research by implementing data policies and data archives. Another aim was to analyse the specifications of these data policies and to determine potential differences and commonalities for the two branches of economic research.In addition, the talk presents the outcome of an evaluation of journals' data archives. In this second study, two issues of each journal equipped with a data policy were checked for accompanying research data. With this additional analysis we aim to estimate whether journals with data policy really enforce data availability.Based on these studies, the talk provides an overview in recent developments of journals' research data management in economic research. The results indicate that especially journals in economics are in a state of flux.

description: We present sub-arcsecond (0.35"-0.9"), near-infrared J,H,K band photometric observations of six fields along the W51 Giant Molecular Cloud (W51 GMC). Our observations reveal four new, embedded clusters and provide a new high-resolution (0.35") view of the W51IRS2 (G49.5-0.4) region. The cluster associated with G48.9-0.3 is found to be a double cluster enclosed in a nest of near-infrared nebulosity. We construct stellar surface density maps for four major clusters in the W51 GMC. These unveil the underlying hierarchical structure. Color-color and color-magnitude diagrams for each of these clusters show clear differences in the embedded stellar populations and indicate the relative ages of these clusters. In particular, the clusters associated with the HII regions G48.9-0.3 and G49.0-0.3 are found to have a high fraction of YSOs and are therefore considered the youngest of all the near-infrared clusters in the W51 GMC. The estimated masses of the individual clusters, when summed, yield a total stellar mass of ~10^4 Msun in the W51 GMC, implying a star formation efficiency of 5-10%. These results in comparision with the CO observations of the W51 GMC, suggest for the first time, that star formation in the W51 GMC is likely triggered by a galactic spiral density wave.

Parametric perspective on highly excited states: case studies of CHBrClF and C2H2

description: Considerable insights can be obtained regarding the nature of highly excited states by computing the eigenbasis expectation values of the resonance operators associated with an effective spectroscopic Hamiltonian. The expectation values are related to the parametric derivative of the eigenvalues with respect to specific resonance strengths i.e., level velocities.Sensitivity of the level velocities to the existence of closed orbits in the underlying classical phase space provides for a dimensionality independent route to a dynamical assignment of the states. In this letter, taking CHBrClF (polyad P=5) and the [16,0]^{g+} bend polyad of C_{2}H_{2} as examples, we show that the level velocities can signal the birth of new modes and highlight sequences of localized eigenstates.

description: HD106906b is an ~11$M_{\mathrm{Jup}}$, ~15Myr old directly-imaged exoplanet orbiting at an extremely large distance from its host star. The wide separation (7.11 arcsec) between HD106906b and its host star greatly reduces the difficulty in direct-imaging observations, making it one of the most favorable directly-imaged exoplanets for detailed characterization. In this paper, we present HST/WFC3/IR time-resolved observations of HD106906b in the F127M, F139M, and F153M bands. We have achieved ~1% precision in the lightcurves in all three bands. The F127M lightcurve demonstrates marginally-detectable ($2.7σ$ significance) variability with a best-fitting period of 4 hr, while the lightcurves in the other two bands are consistent with flat lines. We construct primary-subtracted deep images and use these images to exclude additional companions to HD106906 that are more massive than 4$M_{\mathrm{Jup}}$ and locate at projected distances of more than ~500 au. We measure the astrometry of HD106906b in two HST/WFC3 epochs and achieve precisions better than 2.5 mas. The position angle and separation measurements do not deviate from those in the 2004 HST/ACS/HRC images for more than $1σ$ uncertainty. We provide the HST/WFC3 astrometric results for 25 background stars that can be used as reference sources in future precision astrometry studies. Our observations also provide the first 1.4-micron water band photometric measurement for HD106906b. HD106906b's spectral energy distribution and the best-fitting BT-Settl model have an inconsistency in the 1.4-micron water absorption band, which highlights the challenges in modeling atmospheres of young planetary-mass objects.

description: This paper investigates the inverse problems of determining a space-dependent source for thermoelastic systems of type III under adequate time-averaged or final-in-time measurements and conditions on the time-dependent part of the sought source. Several numerical methods are proposed and examined, including a Landweber scheme and minimisation methods for the corresponding cost functionals, which are based on the gradient and conjugate gradient method. A shortcoming of these methods is that the values of the sought source are fixed ab initio and remain fixed during the iterations. The Sobolev gradient method is applied to overcome the possible inaccessibility of the source values at the boundary. Numerical examples are presented to discuss the different approaches and support our findings based on the implementation on the FEniCSx platform.

description: Protecting superconducting qubits from low-frequency noise is essential for advancing superconducting quantum computation. Based on the application of a periodic drive field, we develop a protocol for engineering dynamical sweet spots which reduce the susceptibility of a qubit to low-frequency noise. Using the framework of Floquet theory, we prove rigorously that there are manifolds of dynamical sweet spots marked by extrema in the quasi-energy differences of the driven qubit. In particular, for the example of fluxonium biased slightly away from half a flux quantum, we predict an enhancement of pure-dephasing by three orders of magnitude. Employing the Floquet eigenstates as the computational basis, we show that high-fidelity single- and two-qubit gates can be implemented while maintaining dynamical sweet-spot operation. We further confirm that qubit readout can be performed by adiabatically mapping the Floquet states back to the static qubit states, and subsequently applying standard measurement techniques. Our work provides an intuitive tool to encode quantum information in robust, time-dependent states, and may be extended to alternative architectures for quantum information processing.

description: Using the constrained curve fitting method and overlap fermions with the lowest pion mass at $180 {\rm MeV}$, we observe that the masses of the first positive and negative parity excited states of the nucleon tend to cross over as the quark masses are taken to the chiral limit. Both results at the physical pion mass agree with the experimental values of the Roper resonance ($N^{1/2+}(1440)$) and $S_{11}$ ($N^{1/2-}(1535)$). This is seen for the first time in a lattice QCD calculation. These results are obtained on a quenched Iwasaki $16^3 \times 28$ lattice with $a = 0.2 {\rm fm}$. We also extract the ghost $η' N$ states (a quenched artifact) which are shown to decouple from the nucleon interpolation field above $m_π \sim 300 {\rm MeV}$. From the quark mass dependence of these states in the chiral region, we conclude that spontaneously broken chiral symmetry dictates the dynamics of light quarks in the nucleon.

description: We present the electronic and structural properties of monolayer WSe$_{2}$ grown by pulsed-laser deposition on monolayer graphene (MLG) on SiC. The spin splitting in the WSe$_{2}$ valence band at $\overline{\mathrm{K}}$ was $Δ_\mathrm{SO}=0.469\pm0.008$ eV by angle-resolved photoemission spectroscopy (ARPES). Synchrotron-based grazing-incidence in-plane X-ray diffraction (XRD) revealed the in-plane lattice constant of monolayer WSe$_{2}$ to be $a_\mathrm{WSe_2}=3.2757\pm0.0008 \mathrm{Å}$. This indicates a lattice compression of -0.19 % from bulk WSe$_{2}$. By using experimentally determined graphene lattice constant ($a_\mathrm{MLG}=2.4575\pm0.0007 \mathrm{Å}$), we found that a 3$\times$3 unit cell of the slightly compressed WSe$_{2}$ is perfectly commensurate with a 4$\times$4 graphene lattice with a mismatch below 0.03 %, which could explain why the monolayer WSe$_{2}$ is compressed on MLG. From XRD and first-principles calculations, however, we conclude that the observed size of strain is negligibly small to account for a discrepancy in $Δ_\mathrm{SO}$ found between exfoliated and epitaxial monolayers in earlier ARPES. In addition, angle-resolved, ultraviolet and X-ray photoelectron spectroscopy shed light on the band alignment between WSe$_{2}$ and MLG/SiC and indicate electron transfer from graphene to the WSe$_{2}$ monolayer. As further revealed by atomic force microscopy, the WSe$_{2}$ island size depends on the number of carbon layers on top of the SiC substrate. This suggests that the epitaxy of WSe$_{2}$ favors the weak van der Waals interactions with graphene while it is perturbed by the influence of the SiC substrate and its carbon buffer layer.

description: We develop a theory of particle acceleration inside relativistic rotating electron-positron force-free jets with spiral magnetic fields. We considered perturbation of the stationary magnetic field structure and found that acceleration takes place in the regions where the Alfven resonant condition with the eigenmodes in the jet is fulfilled, i.e. where the local Alfven speed is equal to the phase speed of an eigenmode. The acceleration mechanism is regular acceleration by the electric field of the electromagnetic wave, which is the eigenmode of the force-free cylindrical jet: particles drift out of the region of the large wave amplitude near the Alfven resonant surface and gain energy. Acceleration in the strong electric field near the Alfven resonance and synchrotron losses combine to form a power-law energy spectrum of ultra-relativistic electrons and positrons with index between 2 and 3 depending upon the initial energy of the injected particles. The power law distribution ranges from 10 MeV to 1000 MeV.

description: Openness is an important aspect of good scientific practice. In this context, data sharing can be seen as a trust-building mechanism: Making underlying data findable and accessible supports reproducibility and confirmability of research results published in journal articles.The presentation gives an overview about the "Replication Server" project, which is an initiative by two leading German sociology journals and GESIS to foster reproducibility in the social sciences. As part of this project, both of the involved journals, "Zeitschrift fur Soziologie" and "Soziale Welt", developed respective data policies. Authors who submit articles based on research data have to agree to make their data available to the community in the case that the article is published. In December 2015 a corresponding service was introduced to support journals in implementing their data policies practically.datorium is an existing GESIS service which provides a user-friendly tool for the documentation, upload and publication of social science research data. Researchers describe their data in a standardized manner. Incoming data will be checked with regard to data privacy, coherence and completeness. All datasets receive a persistent identifier (DOI).For the purposes of the cooperation with the journals, datorium has been extended by additional features. These make it possible to link all data sets to the corresponding articles and vice versa. Users can easily recognise data sets as belonging to an article from the respective journal. Data are accessible via the datorium webpage and access conditions are definedin accordance with the policies of the respective journals.The initiative started with the two mentioned journals but is also open for further partners.

description: We present an analysis of $\emph{VI}$ CCD time series photometry of globular cluster NGC 6712. Our main goal is to study the variable star population as indicators of the cluster mean physical parameters. We employed the Fourier decomposition of RR Lyrae light curves to confirm that $[\rm Fe/H]_{UVES} = -1.0 \pm 0.05$ is a solid estimate. We estimated the reddening to the cluster as $E(B-V)$ = 0.35 $\pm$ 0.04 from the RRab stars colour curves. The distance to the cluster was estimated using three independent methods which yielded a weighted mean distance $\big < d \big>$ = 8.1 $\pm$ 0.2 kpc. The distribution of RRab and RRc stars on the HB shows a clear segregation around the first overtone red edge of the instability strip, which seems to be a common feature in OoI-type cluster with a very red horizontal branch. We carried out a membership analysis of 60,447 stars in our FoV using the data from $Gaia$-DR2 and found 1529 likely members; we possess the light curves of 1100 among the member stars. This allowed us to produce a clean colour-magnitude diagram, consistent with an age of 12 Gyrs, and enabled us to discover close unresolved contaminants for several variable stars. From the proper motion analysis we found evidence of non-member stars in the FoV of the cluster being tidally affected by the gravitational pull of the bulge of the Galaxy. We found that the RRab variable V6, shows a previously undetected Blazhko effect. Finally, we report sixteen new variables of the EW-type (9) and SR-type (7).

description: We have observed continuum emission at lambda = 850 microns over ~4 square degrees of the Ophiuchus star-forming cloud using SCUBA on the JCMT, producing a submillimetre continuum map twenty times larger than previous Ophiuchus surveys. Our sensitivity is 40 mJ/beam, a factor of ~2 less sensitive than earlier maps. Using an automated identification algorithm, we detect 100 candidate objects. Only two new objects are detected outside the boundary of previous maps, despite the much wider area surveyed. We compare the submillimetre continuum map with a map of visual extinction across the Ophiuchus cloud derived using a combination of 2MASS and R-band data. The total mass in submillimetre objects is ~ 50 Msun compared with ~ 2000 Msun in observed cloud mass estimated from the extinction. The submillimetre objects represent only 2.5% of the cloud mass. A clear association is seen between the locations of detected submillimetre objects and high visual extinction, with no objects detected at A_V<7 magnitudes. Using the extinction map, we estimate pressures within the cloud from P/k ~2x10^5 cm^-3 K in the less-extincted regions to P/k ~2x10^6 cm^-3 K at the cloud centre. Given our sensitivities, cold (T_d ~15K) clumps supported by thermal pressure, had they existed, should have been detected throughout the majority of the map. Such objects may not be present at low A_V because they may form only where A_V > 15, by some mechanism (e.g., loss of non-thermal support).

description: The evolution of the magnetic field and plasma quantities inside a coronal mass ejection (CME) with distance are known from statistical studies using data from 1 au monitors, planetary missions, Helios, and Ulysses. This does not cover the innermost heliosphere, below 0.29 au, where no data are yet publicly available. Here, we describe the evolution of the properties of simulated CMEs in the inner heliosphere using two different initiation mechanisms. We compare the radial evolution of these properties with that found from statistical studies based on observations in the inner heliosphere by Helios and MESSENGER. We find that the evolution of the radial size and magnetic field strength is nearly indistinguishable for twisted flux rope from that of writhed CMEs. The evolution of these properties is also consistent with past studies, primarily with recent statistical studies using in situ measurements and with studies using remote observations of CMEs.

description: We study gauged five-dimensional supergravity on the interval [0,πR]. We find a set of boundary conditions with respect to which the theory is locally supersymmetric. For theories with detuned brane tensions (Λ_4<0), we show that these boundary conditions can be used to spontaneously break global supersymmetry. For the original, tuned Randall-Sundrum scenario (Λ_4=0), we prove that the locally supersymmetric boundary conditions are also globally supersymmetric. We lift the theory from [0,πR] to S^1 and R, with arbitrary twists for the fermions, and cast these results in the language of the Scherk-Schwarz mechanism.

description: The aim of this paper is investigating the existence of one or more critical points of a family of functionals which generalizes the model problem \[ \bar J(u)\ =\ \frac1p\ \int_Ω\bar A(x,u)|\nabla u|^p dx - \int_ΩG(x,u) dx \] in the Banach space $X = W^{1,p}_0(Ω)\cap L^\infty(Ω)$, where $Ω\subset {\mathbb R}^N$ is an open bounded domain, $1 < p < N$ and the real terms $\bar A(x,t)$ and $G(x,t)$ are $C^1$ Carathéodory functions on $Ω\times {\mathbb R}$. We prove that, even if the coefficient $\bar A(x,t)$ makes the variational approach more difficult, if it satisfies ``good'' growth assumptions then at least one critical point exists also when the nonlinear term $G(x,t)$ has a suitable supercritical growth. Moreover, if the functional is even, it has infinitely many critical levels. The proof, which exploits the interaction between two different norms on $X$, is based on a weak version of the Cerami-Palais-Smale condition and a suitable intersection lemma which allow us to use a Mountain Pass Theorem.
Collecting Community Experiences of Conflict

description: How do UN peacekeeping missions gather information about local experiences of conflict? What are the effects of personal networks, tensions with national security services and trust in the credibility of the mission? How do these factors influence the reliability and the accuracy of the data produced? Peacekeeping missions gather narratives of security incidents and human rights abuses from local populations in order to monitor the security environment and inform strategic decision-making. The documented incidents create a historical record of the security situation and often constitute one of the few continuous information resources on the conflict. However, relatively little is known about the practices by which this information is amassed, verified and processed. In this key informant study, we talked to five former field officers from the UN mission in Darfur to better understand the methods of incident data collection, evaluation and verification. In particular, we looked at the extent to which the ideals as outlined in formal training and guidelines diverge from the experience of data collection on the ground in Darfur.
Model-Based Deep Learning for Reconstruction of Joint k-q Under-sampled High Resolution Diffusion MRI

description: We propose a model-based deep learning architecture for the reconstruction of highly accelerated diffusion magnetic resonance imaging (MRI) that enables high resolution imaging. The proposed reconstruction jointly recovers all the diffusion weighted images in a single step from a joint k-q under-sampled acquisition in a parallel MRI setting. We propose the novel use of a pre-trained denoiser as a regularizer in a model-based reconstruction for the recovery of highly under-sampled data. Specifically, we designed the denoiser based on a general diffusion MRI tissue microstructure model for multi-compartmental modeling. By using a wide range of biologically plausible parameter values for the multi-compartmental microstructure model, we simulated diffusion signal that spans the entire microstructure parameter space. A neural network was trained in an unsupervised manner using an autoencoder to learn the diffusion MRI signal subspace. We employed the autoencoder in a model-based reconstruction and show that the autoencoder provides a strong denoising prior to recover the q-space signal. We show reconstruction results on a simulated brain dataset that shows high acceleration capabilities of the proposed method.

The Nearby Neutron Star RX J0720.4-3125 from Radio to X-rays

description: We present radio, optical, ultraviolet, and X-ray observations of the isolated, thermally-emitting neutron star RX J0720.4-3125 using the Parkes radio telescope, the Very Large Array, the Hubble Space Telescope, and the Chandra X-ray Observatory. From these data we show that the optical/UV spectrum of RX J0720.4-3125 is not well fit by a Rayleigh-Jeans tail as previously thought, but is instead best fit by either a single non-thermal power-law or a combination of a Rayleigh-Jeans tail and a non-thermal power-law. Taken together with the X-ray spectrum, we find the best model for RX J0720.4-3125 to be two blackbodies plus a power-law, with the cool blackbody implying a radius of 11-13 km at an assumed distance of 300 pc. This is similar to many middle aged (10^{5-6} yr) radio pulsars such as PSR B0656+14, evidence supporting the hypothesis that RX J0720.4-3125 is likely to be an off-beam radio pulsar. The radio data limit the flux at 1.4 GHz to be <0.24 mJy, or a luminosity limit of 4*pi*d^2*F < 3e25*d_300^2 ergs/s, and we see no sign of extended nebulosity, consistent with expectations for a pulsar like RX J0720.4-3125.

Propagation of Ultra-High Energy Cosmic Rays in Extragalactic Magnetic Fields

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In this paper we will discuss the problem of Ultra High Energy Cosmic Rays (UHECR) and show that the idea of a Single Source Model established by Erlykin and Wolfendale (1997) to explain the features seen in cosmic ray energy spectra around the 10**15 eV region can be successfully applied also for the much higher energies. The propagation of UHECR (of energies higher than 10**19 eV) in extragalactic magnetic fields can no longer be described as a random walk (diffusion) process and the transition to rectilinear propagation gives a possible explanation for the so-called Greisen-Zatzepin-Kuzmin (GZK) cut-off which still remains an open question after almost 40 years. A transient "single source" located at a particular distance and producing UHECR for a finite time is the proposed solution.

description: Hippodonta minuta A. Pavlov, Levkov, D.M. Williams & Edlund, sp. nov. (Figs 354–364)
 Type:— KENYA. Lake Turkana (former Lake Rudolf), Northern Frontier, 8 th Jan. 1953, sample 1400.1, collector R. Ross. (holotype: slide BM! 1400.1).
Valves linear-lanceolate, with not protracted, but broadly rounded valve ends. Valve length 12.5–17.0 µm, width 3.5–4.5 µm. Axial area narrow-linear, expanding into a transversely elongated to panduriform central area. Central area forming well-defined fascia. Terminal area clearly distinguishable in LM throughout the size diminution stages, broad and semi-circular in shape. Raphe linear-filiform, with distinct, teardrop-shaped and closely spaced central pores. Terminal pores of raphe distinct, circle-shaped and weakly advancing into the terminal area. Striae coarse, weakly to moderately radiate at the middle, becoming parallel or weakly convergent towards valve ends, 8–12 in 10 µm. Interstriae of equal or lower width than striae. Lineolae composing striae quite densely spaced along a stria, vaguely distinguishable with LM, 3–4 within a stria at the middle of the valve.
 Distribution:— Hippodonta minuta has so far only been observed in Lake Turkana, Kenya. In the type material it is very frequent.
 Observations:—As with regard to the valve outline and the presence of a fully developed fascia, H. minuta from Lake Turkana, Kenya, most closely resembles H. angustata (Figs 329–342) from Lake Tanganyika. However, H. minuta has stronger pronounced and broader striae, as well as more broadly rounded valve ends. With regard to the valve outline, H. minuta is also similar to H. avittata and H. cf. avittata (Lange-Bertalot et al. 1996: figs 1: 35–40). Nevertheless, both of the latter taxa have quite small central areas, never a fully developed fascia, while the fascia in H. minuta is consistent throughout the size diminution stages. In addition, the lineolae of H. avittata and H. cf. avittata are clearly discernible with LM in contrast to H. minuta where the lineolae are barely distinguishable.

description: An analog of Gelfand-Levitan-Marchenko integral equations for multi- dimensional Delsarte transmutation operators is constructed by means of studying their differential-geometric structure based on the classical Lagrange identity for a formally conjugated pair of differential operators. An extension of the method for the case of affine pencils of differential operators is suggested.
