description: In this communication, we focus on possibilities to constrain SME coefficients using Cassini and Messenger data. We present simulations of radioscience observables within the framework of the SME, identify the linear combinations of SME coefficients the observations depend on and determine the sensitivity of these measurements to the SME coefficients. We show that these datasets are very powerful for constraining SME coefficients.

description: Undulatory swimming is a widespread propulsion strategy adopted by many small-scale organisms including various single-cell eukaryotes and nematodes. In this work, we report a comprehensive study of undulatory locomotion of a finite filament using (i) approximate resistive force theory (RFT) assuming a local nature of hydrodynamic interaction between the filament and the surrounding viscous liquid, and (ii) particle-based numerical computations taking into account the intra-filament hydrodynamic interaction. Using the ubiquitous model of a propagating sinusoidal waveform, we identify the limit of applicability of the RFT and determine the optimal propulsion gait in terms of (i) swimming distance per period of undulation and (ii) hydrodynamic propulsion efficiency. The occurrence of the optimal swimming gait maximizing hydrodynamic efficiency at finite wavelength in particle-based computations diverges from the prediction of the RFT. To compare the model swimmer powered by sine wave undulations to biological undulatory swimmers, we apply the particle-based approach to study locomotion of the model organism nematode Caenorhabditis elegans using the swimming gait extracted from experiments. The analysis reveals that even though the amplitude and the wavenumber of undulations are similar to those determined for the best performing sinusoidal swimmer, C. elegans overperforms the latter in terms of both displacement and hydrodynamic efficiency. Further comparison with other undulatory microorganisms reveals that many adopt waveforms with characteristics similar to the optimal model swimmer, yet real swimmers still manage to beat the best performing sine-wave swimmer in terms of distance covered per period. Overall our results underline the importance of further waveform optimization, as periodic undulations adopted by C. elegans and other organisms deviate considerably from a simple sine wave.

description: We have investigated the plastic deformation properties of non-equiatomic single phase Zr-Nb-Ti-Ta-Hf high-entropy alloys from room temperature up to 300 °C. Uniaxial deformation tests at a constant strain rate of 10$^{-4}$ s$^{-1}$ were performed including incremental tests such as stress-relaxations, strain-rate- and temperature changes in order to determine the thermodynamic activation parameters of the deformation process. The microstructure of deformed samples was characterized by transmission electron microscopy. The strength of the investigated Zr-Nb-Ti-Ta-Hf phase is not as high as the values frequently reported for high-entropy alloys in other systems. We find an activation enthalpy of about 1 eV and a stress dependent activation volume between 0.5 and 2 nm$^3$. The measurement of the activation parameters at higher temperatures is affected by structural changes evolving in the material during plastic deformation.

description: Strains strongly affect the properties of low-dimensional materials, such as graphene. By combining in situ, in operando, reflection high energy electron diffraction experiments with first-principles calculations, we show that large strains, above 2%, are present in graphene during its growth by chemical vapor deposition on Ir(111) and when it is subjected to oxygen etching and ion bombardment. Our results unravel the microscopic relationship between point defects and strains in epitaxial graphene and suggest new avenues for graphene nanostructuring and engineering its properties through introduction of defects and intercalation of atoms and molecules between graphene and its metal substrate.

description: Part of a collection of 21 letters sent by William Powell Frith to his great nephew Henry Keyworth Raine, dating from March 16, 1890 to March 29, 1908. William Powell Frith (1819-1909), painter of historical and genre works, including large canvases such as Derby Day (1858). “The Race for Wealth” comprises five paintings, all based around a fictional central character, a corrupt financier called The Spider, and all dealing with the theme of reckless financial speculation. Inspired by characters found in the novels of Charles Dickens and Anthony Trollope, The Spider persuades his victims to invest in dubious schemes. Often compared with Hogarth’s “The Rake’s Progress,” “The Race for Wealth” portrays The Spider’s initial success, his unmasking, his trial, and ends with his imprisonment. This letter shows William praising Henry on his artistic abilities on his latest life-like portrait.

description: Two single-particle sources coupled in series to a chiral electronic waveguide can serve as a probabilistic source of two-particle excitations with tunable properties. The second-order correlation function, characterizing the state of emitted electrons in space-time, is expressed in terms of the Floquet scattering matrix of a source. It is shown that the Fourier transform of the correlation function, characterizing the emitted state in energy space, can be accessed with the help of an energy resolved shot-noise measurement. The two-electron state emitted adiabatically is discussed in detail. In particular, the two-electron wave function is represented via two different sets of single-particle wave functions accessible experimentally.

Bi-Local Baryon Interpolating Fields with Three Flavours

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Fierz identities follow from permutations of quark indices and thus determine which chiral multiplets of baryon fields are Pauli-allowed, and which are not. In a previous paper we have investigated the Fierz identities of baryon fields with two light flavours and found that all bilocal fields that can be constructed from three quarks are Pauli-allowed. That does not mean that all possible chiral multiplets exist, however: some chiral multiplets do not appear among structures with a given spin in the local limit, say J = 1/2. One such chiral multiplet is the [(6,3)+(3,6)], which is necessary for a successful chiral mixing phenomenology. In the present paper we extend those methods to three light flavors, i.e. to SU_F(3) symmetry and explicitly construct all three necessary chiral SU_L(3)*SU_R(3) multiplets, viz. [(6,3)+(3,6)], [(3,3_bar)+(3_bar,3)] and [(3_bar,3)+(3,3_bar)] that are necessary for a phenomenologically successful chiral mixing. We complete this analysis by considering some bi-local baryon fields that are sufficient for the construction of the "missing" spin 1/2 baryon interpolating fields. Bi-local baryon fields have definite total angular momentum only in the local limit. The physical significance of these results lies in the fact that they show that there is no need for higher Fock space components, such as the (q^4 q_bar), in the baryon chiral mixing framework, for the purpose of fitting the observed axial couplings and magnetic moments: all of the sufficient "mirror components" exist as bi-local fields.

Active galactic nucleus torus models and the puzzling infrared spectrum of IRAS F10214+4724

description: We present a revised model for the infrared emission of the hyperluminous infrared galaxy IRAS F10214+4724 which takes into account recent photometric data from Spitzer and Herschel that sample the peak of its spectral energy distribution. We first present and discuss a grid of smooth active galactic nucleus (AGN) torus models computed with the method of Efstathiou & Rowan-Robinson and demonstrate that the combination of these models and the starburst models of Efstathiou and coworkers, while able to give an excellent fit to the average spectrum of Seyfert 2s and spectra of individual type 2 quasars measured by Spitzer, fails to match the spectral energy distribution of IRAS F10214+4724. This is mainly due to the fact that the nuSnu distribution of the galaxy falls very steeply with increasing frequency (a characteristic that is usually indicative of heavy absorption by dust) but shows a silicate feature in emission. Such emission features are not expected in sources with optical/near-infrared type 2 AGN spectral signatures. The Herschel data show that there is more power emitted in the rest-frame 20-50um wavelength range compared with the model presented by Efstathiou which assumes three components of emission: an edge-on torus, clouds (at a temperature of 610 and 200K) that are associated with the narrow-line region (NLR) and a highly obscured starburst that dominates in the submillimetre. We present a revised version of that model that assumes an additional component of emission which we associate with NLR clouds at a temperature of 100K. The 100K dust component could also be explained by a highly obscured hot starburst. The model suggests that the NLR of IRAS F10214+4724 has an unusually high covering factor (>= 17%) or more likely the magnification of the emission from the NLR clouds is significantly higher than that of the emission from the torus.

A Lossy Graph Model for Decoding Delay Reduction in Instantly Decodable Network Coding

description: In this paper, we study the broadcast decoding delay performance of generalized instantly decodable network coding (G-IDNC) in the lossy feedback scenario. The problem is formulated as a maximum weight clique problem over the G-IDNC graph in [1]. In order to further minimize the decoding delay, we introduce in this paper the lossy G-IDNC graph (LG-IDNC). Whereas the G-IDNC graph represents only doubtless combinable packets, the LG-IDNC graph represents also uncertain packet combinations when the expected decoding delay of the encoded packet is lower than the individual expected decoding delay of each packet encoded in it. Since the maximum weight clique problem is known to be NP-hard, we use the heuristic introduced in [2] to discover the maximum weight clique in the LG-IDNC graph and finally we compare the decoding delay performance of LG-IDNC and G-IDNC graphs through extensive simulations. Numerical results show that our new LG-IDNC graph formulation outperforms the G-IDNC graph formulation in all situations and achieves significant improvement in the decoding delay especially when the feedback erasure probability is higher than the packet erasure probability.

description: Isolated Majorana fermion states can be produced at the boundary of a topological superconductor in a quasi-one-dimensional geometry. If such a superconductor is connected to a disordered quantum wire, the Majorana fermion is spread into the wire, subject to Anderson localization. We study this effect in the limit of a thick wire with broken time-reversal and spin-rotational symmetries. With the use of a supersymmetric nonlinear sigma model, we calculate the average local density of states in the wire as a function of energy and of the distance from the interface with the superconductor. Our results may be qualitatively explained by the repulsion of states from the Majorana level and by Mott hybridization of localized states.

description: We propose a smart contract that allows two mutually distrusting parties to transact any non-digital good or service by deploying a smart contract on a blockchain to act as escrow. The contract settles disputes by letting parties wager that they can convince an arbiter that they were the honest party. We analyse the contract as an extensive-form game and prove that the honest strategy is secure in a strong game-theoretic sense if and only if the arbiter is biased in favor of honest parties. By relaxing the security notion, we can replace the arbiter by a random coin toss. Finally, we show how to generalize the contract to multiparty transactions in a way that amortizes the transaction fees.

description: The Area Under the the Receiver Operating Characteristics (ROC) Curve, referred to as AUC, is a well-known performance measure in the supervised learning domain. Due to its compelling features, it has been employed in a number of studies to evaluate and compare the performance of different classifiers. In this work, we explore AUC as a performance measure in the unsupervised learning domain, more specifically, in the context of cluster analysis. In particular, we elaborate on the use of AUC as an internal/relative measure of clustering quality, which we refer to as Area Under the Curve for Clustering (AUCC). We show that the AUCC of a given candidate clustering solution has an expected value under a null model of random clustering solutions, regardless of the size of the dataset and, more importantly, regardless of the number or the (im)balance of clusters under evaluation. In addition, we elaborate on the fact that, in the context of internal/relative clustering validation as we consider, AUCC is actually a linear transformation of the Gamma criterion from Baker and Hubert (1975), for which we also formally derive a theoretical expected value for chance clusterings. We also discuss the computational complexity of these criteria and show that, while an ordinary implementation of Gamma can be computationally prohibitive and impractical for most real applications of cluster analysis, its equivalence with AUCC actually unveils a much more efficient algorithmic procedure. Our theoretical findings are supported by experimental results. These results show that, in addition to an effective and robust quantitative evaluation provided by AUCC, visual inspection of the ROC curves themselves can be useful to further assess a candidate clustering solution from a broader, qualitative perspective as well.

description: We report a calculation reduction method for color computer-generated holograms (CGHs) using color space conversion. Color CGHs are generally calculated on RGB space. In this paper, we calculate color CGHs in other color spaces: for example, YCbCr color space. In YCbCr color space, a RGB image is converted to the luminance component (Y), blue-difference chroma (Cb) and red-difference chroma (Cr) components. In terms of the human eye, although the negligible difference of the luminance component is well-recognized, the difference of the other components is not. In this method, the luminance component is normal sampled and the chroma components are down-sampled. The down-sampling allows us to accelerate the calculation of the color CGHs. We compute diffraction calculations from the components, and then we convert the diffracted results in YCbCr color space to RGB color space.

description: Antibodies - key molecules of the immune system - are increasingly used as ther-

apeutic drugs. The variable domain of the antibody is responsible for binding to

an antigen and contains polypeptide loops, each referred to as a ‘Complemen-

tarity Determining Region (CDR)’. Five of these loops can be modelled with

acceptable accuracy but so far, the sixth (CDR-H3) remains more difficult for

all but the shortest loops.

Various methods have been attempted to model this CDR, and while accu-

racy has improved, more improvement is still needed. One such method is to

apply machine learning in an attempt to discern which features of a sequence

lead to what final conformation; such an approach was tested in 1995. Since

that time, the number of structures available for learning has increased dra-

matically, as have methods and technologies available for building and training

neural networks.

This work revisits the neural network approach to modelling and scoring

CDR-H3 in light of these advances. We conclude that several common neural

network architectures cannot accurately model CDR-H3 from sequence alone,

but show reasonable performance in selecting a good candidate from a large set.

description: We have analysed RXTE archival data to study the aperiodic variability of the black-hole binary GRO J1655-40 during the hard state of the 2005 outburst. We computed the 0.008-64 Hz power spectral density during the rise and decay of the 2005 outburst, and we found that they were reasonably well modelled by the sum of two, broad Lorenztian functions in most cases (plus a narrow QPO) which correspond to three different variability components. Our aim is to study the evolution of the timing properties of the source during the outburst, by studying the correlation between the characteristics of the broad-band noise components in the power spectra and the source luminosity. Our results suggest that the whole power spectrum shifts to high (low) frequencies as the source luminosity increases (decreases), in agreement with previous studies of other black hole binaries. However, we also detect a strong "hysteresis" pattern in the "frequency-luminosity" plots, and show that the "critical" luminosity limit, above which the timing properties of the source change, is different during the rise and the decay phase of the outburst. We discuss the general implications of these results in the context of the truncated disc model.

description: We re-analyse the recently published HARPS and PFS velocities of the nearby K dwarf GJ 221 that have been reported to contain the signatures of two planets orbiting the star. Our goal is to see whether the earlier studies discussing the system fell victims of false negative detections. We perform the analyses by using an independent statistical method based on posterior samplings and model comparisons in the Bayesian framework that is known to be more sensitive to weak signals of low-mass planets. According to our analyses, we find strong evidence in favour of a third candidate planet in the system corresponding to a cold sub-Saturnian planet with an orbital period of 500 days and a minimum mass of 29 $M_{\oplus}$. Application of sub-optimal signal detection methods can leave low-amplitude signals undetected in radial velocity time-series. Our results suggest that the estimated statistical properties of low-mass planets can thus be biased because several signals corresponding to low-mass candidate planets may have gone unnoticed. This also suggests that the occurrence rates of such planets based on radial velocity surveys might be underestimated.

description: The Specialized Information Service for Solid Earth Geosciences (FID GEO) addresses the digital supply of

open and reusable research results. The FID GEO offers services for the scientific community, but also the

public benefits from open access to scientific literature, maps and research data.

The FID GEO supports the scientific community in the areas of

1) open access e-publication of institutional and "grey" literature as well as pre- and postprints of scientific

articles,

2) digitisation of geoscience literature and maps and

3) publication of research data related to scientific articles (data supplements).

Below, recent activities of the FID GEO are described and services are illustrated with examples to point out

the benefits for researchers and for science in general.

Currently, the FID GEO is commissioned to digitise older issues of the journal "Zeitschrift für Geophysik" on

behalf of the German Geophysical Society. These issues, so far print-only, are to be published electronically

and freely available (open access) on the repository of the FID GEO (e-docs.geo-leo.de). While digitisation is

funded by the FID GEO, the primary challenge is to clarify the legal situation for publication.

Regarding research data, GFZ Data Services is the partner of the FID GEO, providing the repository for data

publication and associated services. The FID GEO presently focuses on raising awareness in the scientific

community to the issues of data publishing. The FID GEO promotes the implementation of the standards

formulated in the "Statement of commitment" of the "Coalition for publishing data in the Earth and Space

Sciences (COPDESS)" and adherence to the "FAIR data principles". The scientific community is approached

via existing networks such as learned societies and their umbrella organizations, the DVGeo and the

GeoUnion, and also research networks like Geo.X in the Berlin-Brandenburg region. In consultation with the

scientific community, model workflows are developed for the publication of research data.

Since 2016 the FID GEO is funded by the German Research Council (Deutsche Forschungsgemeinschaft)

and hosted by the SUB Göttingen and the German Research Center for Geosciences GFZ.

description: LiFeAs is unique among the arsenic based Fe-pnictide superconductors because it is the only nearly stoichiometric compound which does not exhibit magnetic order. This is at odds with electronic structure calculations which and a very stable magnetic state and predict cylindrical hole- and electron-like Fermi surface sheets whose geometry suggests spin uctuations and a possible instability toward long-range ordering at the nesting vector. In fact, a complex magnetic phase-diagram is indeed observed in the isostructural NaFeAs compound. Previous angle resolved photoemission (ARPES) experiments revealed the existence of both hole and electron-like surfaces, but with rather distinct cross-sectional areas and an absence of the nesting that is thought to underpin both magnetic order and superconductivity in the pnictide family of superconductors. These ARPES observations were challenged by subsequent de Haas van Alphen (dHvA) measurements which detected a few, electron like Fermi surface sheets in rough agreement with the original band calculations. Here, we show a detailed dHvA study unveiling additional, small and nearly isotropic Fermi surface sheets in LiFeAs single crystals, which ought to correspond to hole-like orbits, as previously observed by ARPES. Therefore, our results conciliate the apparent discrepancy between ARPES and the previous dHvA results5. The small size of these Fermi surface pockets suggests a prominent role for the electronic correlations in LiFeAs. The absence of gap nodes, in combination with the coexistence of quasi-two-dimensional and three-dimensional Fermi surfaces, favor a s-wave pairing symmetry for LiFeAs. But similar electron-like Fermi surfaces combined with very different hole pockets between LiFeAs and LiFeP, suggest that the nodes in the gap function of LiFeP might be located on the hole-pockets.

description: Given a surface $S$ in a 3D contact sub-Riemannian manifold $M$, we investigate the metric structure induced on $S$ by $M$, in the sense of length spaces. First, we define a coefficient $\widehat K$ at characteristic points that determines locally the characteristic foliation of $S$. Next, we identify some global conditions for the induced distance to be finite. In particular, we prove that the induced distance is finite for surfaces with the topology of a sphere embedded in a tight coorientable distribution, with isolated characteristic points.

title: A Call for Ethical and Responsible Treatment of Invasive Species by Recreational Anglers
Creators: name: Adeli, Kevin A
Publisher: name: Utah State University

description: Invasive species pose a prominent threat to global biodiversity, with aquatic ecosystems being particularly susceptible. In an effort to limit the spread of aquatic invasive species, numerous public awareness programs have been launched, and several regions have enacted “must-kill” angling regulations, which prohibit the live release of invasive fish species when captured. Many education programs, however, demonize invasive species and lack any instruction for humane euthanasia. This unbalanced approach has translated into widespread mistreatment of invasive species among recreational anglers. This piece addresses these concerns by discussing their significance and providing recommendations for how education programs can adopt a more comprehensive approach to mitigate this issue.

description: The structural features of polystyrene brushes grafted on spherical silica nanoparticles immersed in polystyrene are investigated by means of a Monte Carlo methodology based on polymer mean field theory. The nanoparticle radii (either 8 nm or 13 nm) are held constant, while the grafting density and the lengths of grafted and matrix chains are varied systematically in a series of simulations. The primary objective of this work is to simulate realistic nanocomposite systems of specific chemistry at experimentally accessible length scales and study the structure and scaling of the grafted brush. The profiles of polymer density around the particles are examined; based on them, the brush thickness of grafted chains is estimated and its scaling behavior is compared against theoretical models and experimental findings. Then, neutron scattering spectra are predicted both from single grafted chains and from the entire grafted corona. It is found that increasing both the grafting density and the grafted chain molar mass drastically alters the brush dimensions, affecting the wetting behavior of the polymeric brush. On the contrary, especially for particles dispersed in high molecular weight matrix, variation of the matrix chain length causes an almost imperceptible change of the density around the particle surface.

description: We characterize the lifting property (LP) of a separable $C^*$-algebra $A$ by a property of its maximal tensor product with other $C^*$-algebras, namely we prove that $A$ has the LP if and only if for any family $(\{D_i\mid i\in I\}$ of $C^*$-algebras the canonical map $$ {\ell_\infty(\{D_i\}) \otimes_{\max} A}\to {\ell_\infty(\{D_i \otimes_{\max} A\}) }$$ is isometric. Equivalently, this holds if and only if $M \otimes_{\max} A= M \otimes_{\rm nor} A$ for any von Neumann algebra $M$.

description: There are 8 species of bears (Ursidae) in the world; of these, 6 species are known to occur in Asia. However, in Bhutan, there are only 2 species: the Asiatic black bear (Ursus thibetanus) and the sloth bear (Melursus ursinus). The Asiatic black bear is legally protected by the Forest and Nature Conservation Act of Bhutan 1995. The bear is categorized as vulnerable by the International Union for Conservation of Nature and also included under Appendix I of the Convention on International Trade in Endangered Species. Human–bear conflicts are prevalent in Bhutan, especially at the village level where the livelihood consists of livestock rearing and agricultural farming. We have observed a symbiotic relationship between local people and bears in Phrumsengla National Park in Bhutan.
title: Bear-Caused Human Fatalities in Yellowstone National Park: Characteristics and Trends

description: Three fatal bear (Ursus spp.) attacks in Yellowstone National Park (YNP), USA, from 2011 to 2015 were a catalyst for YNP managers to evaluate the circumstances of bear-caused fatalities as well as the bear safety messages it distributes to park visitors. I reviewed records of all fatal bear attacks that occurred in YNP from 1872 to 2018. Seven of the 8 fatalities were caused by grizzly bears (U. arctos horribilis). The per capita risk of being killed by a grizzly bear was 1 fatality for every 26.2 million park visits. Most fatal bear attacks in YNP involved surprise encounters and/or bears conditioned to human foods. Only 1 fatal bear attack was classified as predatory. Most fatal bear attacks involved men (75%), small party sizes of(88%), and occurred in remote backcountry areas (75%). Although the frequency of fatal bear attacks appears to have increased in recent years, the per capita risk of fatal bear attacks has declined. A few human behavioral modifications for recreating in bear country, including hiking with minimum group sizes ≥3 people, remaining on designated trails when hiking, not running from bears during encounters, and carrying bear spray when recreating in bear country have the potential to reduce the risk of fatal bear attacks in the park. Preventing bears from becoming conditioned to anthropogenic foods and garbage is another important factor in reducing bear-caused human fatalities.

description: Der Beitrag untersucht den Einfluss von sozialer Unterstützung und Arbeitsengagement auf die transformationale Führung bei 2’011 Schulleitungen an Schweizer Schulen in sozial benachteiligten und nicht benachteiligten Lagen. Die Ergebnisse zeigen, dass Arbeitsengagement und soziale Unterstützung mit transformationaler Führung zusammenhängen, unabhängig von der Lage. Jedoch weisen Schulleitungen an Schulen in sozial benachteiligter Lage ein geringeres Arbeitsengagement und eine geringer ausgeprägte transformationale Führung auf. Wiederum besteht ein Zusammenhang zwischen sozialer Unterstützung und dem Arbeitsengagement. Schulleitungen, die eine stärkere Unterstützung im Kollegium erfahren, zeigen ein höheres Arbeitsengagement und dadurch eine stärker ausgeprägte transformationale Führung.
