description: The silicon-vacancy center in diamond offers attractive opportunities in quantum photonics due to its favorable optical properties and optically addressable electronic spin. Here, we combine both to achieve all-optical coherent control of its spin states. We utilize this method to explore spin dephasing effects in an impurity-rich sample beyond the limit of phonon-induced decoherence: Employing Ramsey and Hahn-echo techniques at 12mK base temperature we identify resonant coupling to a substitutional nitrogen spin bath as the limiting decoherence source for the electron spin.

description: Diatoms are the most diverse lineage of algae and at the base of most aquatic food webs, but only 11 of their mitochondrial genomes have been described. Herein, we present the mitochondrial genomes of six diatom species, including: Melosira undulata, Nitzschia alba, Surirella sp., Entomoneis sp., Halamphora coffeaeformis, and Halamphora calidilacuna. Comparison of these six genomes to the 11 currently published diatom mitochondrial genomes revealed a novel ubiquitous feature block consisting of tatC-orf157-rps11. The presence of intronic retrotransposable elements in the barcoding region of cox1 in the Halamphora genomes may explain historic difficulty (especially PCR) with cox1 as a universal barcode for diatoms. Our analysis suggests that high rates of variability in number and position of introns, in many commonly used coding sequences, prevent these from being universally viable as barcodes for diatoms. Therefore, we suggest researchers examine the chloroplast and/or nuclear genomes for universal barcoding markers.

description: In this paper we connect algebraic properties of the pair-of-pants product in local Floer homology and Hamiltonian dynamics. We show that for an isolated periodic orbit the product is non-uniformly nilpotent and use this fact to give a simple proof of the Conley conjecture for closed manifolds with aspherical symplectic form. More precisely, we prove that on a closed symplectic manifold the mean action spectrum of a Hamiltonian diffeomorphism with isolated periodic orbits is infinite.

description: The Arctic PASSION project is described in more detail in the project website which is available at https://arcticpassion.eu/. The purpose of Arctic PASSION is creation and implementation of a coherent, integrated Arctic observing system. This implies integrating already existing observing systems in a system of systems approach as well addressing gaps in the current observing system. Arctic PASSION will generate data through the project implementation, but equally important is to map and establish access to already existing datasets in support of the pilot services and other activities of Arctic PASSION. 

Within Work Package 4 - INNOVATING USER-DRIVEN ARCTIC EUROGEO PILOT SERVICES, task 4.3 implements the Pilot Service State of the Arctic Environment. The ambition of this is to provide the latest scientific information in a simple manner. As part of this task a dedicated effort is focusing on development of a tool that provides interactive visualisation of sea ice information. This document provides information on the tool.
The use of stereo video as a training media in the mining industry

Subjects: subject: 80111 Virtual Reality and Related Simulation
subject: FOS: Computer and information sciences

description: The objective of this research was to investigate the use of stereo video as a component of multimedia training materials in contexts where three-dimensional cues are particularly important. The particular application area investigated was the splicing of conveyor belts in the mining industry. The research has practical significance because it is a technique that has wide applicability in areas where training costs are high or involve dangerous activities.
The work is built upon a background of telepresence and virtual reality where simulated training environments are helping to reduce the costs and physical risks associated with training. Pairs of video clips were produced: each pair consisting of a two-dimensional and a three-dimensional clip. The three dimensional video was captured on a pair of video cameras arranged in such a way as to capture the binocular disparity needed for a three-dimensional depth cue. The two videos were then manipulated into a single file that could be played back on a PC and viewed by a person wearing VREX shutterglasses.
A group of volunteers undertook a trial of the application to determine if they could see differences between the two-dimensional and three-dimensional videos and whether they thought it made a positive difference to the learning process. Hardware limitations reduced the viewing size of the video on the screen, and reduced the frame rate at which the video could be replayed.
A number of hardware limitations were discovered which should be able to be overcome with increasing performance in processor and bus speeds. The technique shows promise for training in the mining industry.

description: The anatomy of African lacertid lizards (Lacertidae: Eremiadini) is poorly known, which has hindered a better understanding of their evolutionary relationships. This applies especially to the East African clade, which includes the genera Nucras, Latastia, Philochortus, Pseuderemias and Heliobolus. We present a detailed description of the skull osteology of the genus Heliobolus using X-ray microcomputed tomography and compare its morphology to the above lacertid taxa. Because the genus Heliobolus includes species of doubtful validity and affinities (Heliobolus neumanni and Heliobolus nitidus), we also present a detailed intrageneric comparison and construct a morphological character matrix that we analyse against a phylogenetic backbone derived from previous molecular studies. Heliobolus lugubris and Heliobolus spekii can be well characterised as a monophyletic group on the basis of a short postorbital and a continuously broad posterior margin of the parietal, differing from H. nitidus and other members of the East African clade in an overall low degree of ossification and reduced ventral extension of the frontal bone. Our preliminary phylogenetic analysis suggests that the genus Heliobolus is currently polyphyletic. We propose that the name H. neumanni be officially retracted, because specimens assigned to this species show very different morphologies relative to each other and are placed in different parts of the tree in our analysis. Also, the type specimen is lost and no specimens were collected from the type locality. H. nitidus shows a signal towards the genus Latastia. A definitive, new generic assignment of H. nitidus must await further investigations based on molecular data.

description: The nuclear spin in the vicinity of a nitrogen-vacancy (NV) center possesses of long coherence time and convenient manipulation assisted by the strong hyperfine interaction with the NV center. It is suggested for the subsequent quantum information storage and processing after appropriate initialization. However, current experimental schemes are either sensitive to the inclination and magnitude of the magnetic field or require thousands of repetitions to achieve successful realization. Here, we propose polarizing a 13C nuclear spin in the vicinity of an NV center via a dark state. We demonstrate theoretically that it is robust to polarize various nuclear spins with different hyperfine couplings and noise strengths.

Schmid's Formula for Higher Local Fields

description: In local class field theory, the Schmid-Witt symbol encodes interesting data about the ramification theory of $p$-extensi-ons of $K$ and can, for example, be used to compute the higher ramification groups of such extensions. In 1936, Schmid discovered an explicit formula for the Schmid-Witt symbol of Artin-Schreier extensions of local fields. Later, his formula was generalized to Artin-Schreier-Witt extensions, but still over a local field. In this paper we generalize Schmid's formula to compute the Artin-Schreier-Witt-Parshin symbol for Artin-Schreier-Witt extensions of two-dimensional local fields of positive characteristic.

description: We use zoom hydrodynamical simulations to investigate the properties of satellites within galaxy-sized dark-matter haloes with different assembly histories. We consider two classes of haloes at redshift $z=0$: `stalled' haloes that assembled at $z>1$ and `accreting' ones that are still forming nowadays. Previously, we showed that the stalled haloes are embedded within thick filaments of the cosmic web while the accreting ones lie where multiple thin filaments converge. We find that satellites in the two classes have both similar and different properties. Their mass spectra, radial count profiles, baryonic and stellar content, and the amount of material they shed are indistinguishable. However, the mass fraction locked in satellites is substantially larger for the accreting haloes as they experience more mergers at late times. The largest difference is found in the satellite kinematics. Substructures fall towards the accreting haloes along quasi-radial trajectories whereas an important tangential velocity component is developed, before accretion, while orbiting the filament that surrounds the stalled haloes. Thus, the velocity anisotropy parameter of the satellites ($β$) is positive for the accreting haloes and negative for the stalled ones. This signature enables us to tentatively categorize the Milky Way halo as stalled based on a recent measurement of $β$. Half of our haloes contain clusters of satellites with aligned orbital angular momenta corresponding to flattened structures in space. These features are not driven by baryonic physics and are only found in haloes hosting grand-design spiral galaxies, independently of their assembly history.

description: Describing the space–time evolution of urban population is a fundamental challenge in the science of cities, yet a complete theoretical treatment of the underlying dynamics is still missing. Here, we first reconstruct the evolution of London (UK) over 180 years and show that urban growth consists of an initial phase of diffusion-limited growth, followed by the development of the railway transport network and a consequential shift from central to suburban living. Such dynamics—which are analogous to angiogenesis in biological systems—can be described by a minimalist reaction–diffusion model coupled with economic constraints and an adaptive transport network. We then test the generality of our approach by reproducing the evolution of Sydney, Australia, from 1851 to 2011. We show that the rail system coevolves with urban population, displaying hierarchical characteristics that remain constant over time unless large-scale interventions are put in place to alter the modes of transport. These results demonstrate that transport schemes are first-order controls of long-term urbanization patterns and efforts aimed at creating more sustainable and healthier cities require careful consideration of population-transport feedbacks.

description: The objectives of this study were to develop an expert system for an area of taxation law and to investigate issues associated with expert system development methods, explanation facilities, human -computer interface design and the use of expert systems as learning tools. An expert system giving advice on capital gains tax was developed and shown to be acceptable for use outside the development environment. Reported empirical research concerning operational expert systems is sparse and the research in this study was of an exploratory nature. System development was an incremental process, with successiveversions of the system tested with users and then modified according to test results. The explanation facility goes beyond the usual How and Why explanations offered in expert systems and is based on an analysis of the categories of questions which occur in everyday language. Intermediate steps in calculations can he viewed in a worksheet style screen or report as an explanatory device. In the development of the expert system findings and guidelines from research into human - computer interface design for more conventional systems were followed. The approach adopted led to a user -centred system rather than variable user -modelling, the avoidance of anthromorphism, and the use of menus and a form fill-in interface for input rather than natural language. Trials showed that the system gave valid advice, useful in a professional situation, and that both the explanation facility and the human - computer interface were acceptable to users. Coding for the human interface comprised almost 50% of the whole system. Previous researchers have suggested that an expert system which does not include tutoring expertise is not a good teaching device, though there is little experimental work on the topic. Results from this study indicated that the expert tax system has value as a learning tool when supported by auxiliary printed example problems and used by adults with some prior knowledge of the subject matter

description: WTe2 has attracted a great deal of attention because it exhibits extremely large and nonsaturating magnetoresistance. The underlying origin of such a giant magnetoresistance is still under debate. Utilizing laser-based angle-resolved photoemission spectroscopy with high energy and momentum resolutions, we reveal the complete electronic structure of WTe2. This makes it possible to determine accurately the electron and hole concentrations and their temperature dependence. We find that, with increasing the temperature, the overall electron concentration increases while the total hole concentration decreases. It indicates that the electron-hole compensation, if it exists, can only occur in a narrow temperature range, and in most of the temperature range there is an electron-hole imbalance. Our results are not consistent with the perfect electron-hole compensation picture that is commonly considered to be the cause of the unusual magnetoresistance in WTe2. We identified a flat band near the Brillouin zone center that is close to the Fermi level and exhibits a pronounced temperature dependence. Such a flat band can play an important role in dictating the transport properties of WTe2. Our results provide new insight on understanding the origin of the unusual magnetoresistance in WTe2.

description: COVID-19, a severe acute respiratory syndrome has had multifaceted effects on human lives, society, and economic activities all over the world since its initial outbreak in late December 2019. The health emergency has led to rigorous worldwide containment measures for minimizing the spread of the virus in terms of social distancing, limitation of industrial production, human activities and transportations which have also had some positive impact on the atmospheric environment with less human engagement. Dehiwala- Mount Lavinia Divisional Secretariat Division (DSD) is the largest suburban area in Sri Lanka and holds the second highest population in the country. The present study aims to investigate its environmental status during COVID-19 pandemic travel restrictions and highlight the importance of the risk of Urban Heat Island (UHI) and its interactions with global climate change.Land surface temperature (LST) and Normalized Difference Vegetation Index (NDVI) during the lockdown period (April, 2020) and the normal working period (April, 2019) in Dehiwala-Mount Lavinia DSD. The Landsat 8 satellite images were used for the research study, and the processing was accomplished in the ArcMap 10.5 using Mono window Algorithm.Results exhibited that, the LST is reduced and NDVI is increased during the lockdown phase than the normal working periods which highlights the reduction of transportation related pollution and anthropogenic activities which are the major influencers behind lowering of the LST. It also indicates negative correlation between the LST-NDVI. Further investigation indicated that some of the high temperature zones are permanent, and that the Aththidiya wetland has greatly reduced the surface temperature of the eastern portion of the Dehiwala-Mount Lavinia division.Therefore, it is a timely requirement to set up suitable strategies for the mitigation and the adaptation to UHI and other related causes and it is recommended to establish a permanent national network for monitoring the development of the UHI and implementing mitigatory measures through policymaking.

description: New high-resolution Very Long Baseline Interferometer observations of the prominent jet in the M87 radio galaxy show a persistent triple-ridge structure of the transverse 15-GHz profile with a previously unobserved ultra-narrow central ridge. This radio structure can reflect the intrinsic structure of the jet, so that the jet as a whole consists of two embedded coaxial jets. A relativistic magnetohydrodynamic model is considered in which an inner jet is placed inside a hollow outer jet and the electromagnetic fields, pressures and other physical quantities are found. The entire jet is connected to the central engine that plays the role of a unipolar inductor generating voltage between the jets and providing opposite electric currents, and the charge neutrality and current closure together with the electromagnetic fields between the jets can contribute to the jet stabilization. The constant voltage is responsible for the similar widening laws observed for the inner and outer jets. This jet-in-jet structure can indicate simultaneous operation of two different jet-launching mechanisms, one relating to the central supermassive black hole and the other to the surrounding accretion disc. An inferred magnetic field of 80 G at the base is sufficient to provide the observed jet luminosity.

description: Using Ensemble Monte Carlo simulations the photocurrent in a 500nm long strained [110] silicon nanowire with diameter of 3.1 nm is investigated. It was observed that a phototransistor based on this nanowire can have responsivities in the order of 21.3 mA/W for an input light wavelength of 532 nm and intensity of 0.25-2.5 kW/cm2. The super-unity slope of 1.2 in photo conductance versus input light intensity suggests that the nanowire has a photoconductive gain and highlights its advantage over germanium nanowires with sub-unity slope (0.77). The generated photocurrents are in the 0.1 nA-1 nA range. Density Functional Theory (DFT) and Tight Binding (TB) methods were used for strain application and band structure calculation, respectively. Both longitudinal acoustic and optical phonons were included in the calculation of the carrier-phonon scattering events, which showed a two-order of magnitude stronger role for longitudinal optical phonons.

description: A microscopic theory of the spin Peltier effect in a bilayer structure comprising a paramagnetic metal (PM) and a ferromagnetic insulator (FI) based on the nonequilibrium Green's function method is presented. Spin current and heat current driven by temperature gradient and spin accumulation are formulated as functions of spin susceptibilities in the PM and the FI, and are summarized by Onsager's reciprocal relations. By using the current formulae, we estimate heat generation and absorption at the interface driven by the heat-current injection mediated by spins from PM into FI.

description: In many biomedical, science, and engineering problems, one must sequentially decide which action to take next so as to maximize rewards. One general class of algorithms for optimizing interactions with the world, while simultaneously learning how the world operates, is the multi-armed bandit setting and, in particular, the contextual bandit case. In this setting, for each executed action, one observes rewards that are dependent on a given 'context', available at each interaction with the world. The Thompson sampling algorithm has recently been shown to enjoy provable optimality properties for this set of problems, and to perform well in real-world settings. It facilitates generative and interpretable modeling of the problem at hand. Nevertheless, the design and complexity of the model limit its application, since one must both sample from the distributions modeled and calculate their expected rewards. We here show how these limitations can be overcome using variational inference to approximate complex models, applying to the reinforcement learning case advances developed for the inference case in the machine learning community over the past two decades. We consider contextual multi-armed bandit applications where the true reward distribution is unknown and complex, which we approximate with a mixture model whose parameters are inferred via variational inference. We show how the proposed variational Thompson sampling approach is accurate in approximating the true distribution, and attains reduced regrets even with complex reward distributions. The proposed algorithm is valuable for practical scenarios where restrictive modeling assumptions are undesirable.

description: We consider an arbitrary quantum system coupled non perturbatively to a large arbitrary and fully quantum environment. In [G. Ithier and F. Benaych-Georges, Phys. Rev. A 96, 012108 (2017)] the typicality of the dynamics of such an embedded quantum system was established for several classes of random interactions. In other words, the time evolution of its quantum state does not depend on the microscopic details of the interaction. Focusing at the long time regime, we use this property to calculate analytically a new partition function characterizing the stationary state and involving the overlaps between eigenvectors of a bare and a dressed Hamiltonian. This partition function provides a new thermodynamical ensemble which includes the microcanonical and canonical ensembles as particular cases. We check our predictions with numerical simulations.

description: The huge amount of methane hydrate deposits identified in deep marine sediments is considered as the new resource for future energy. Since carbonates are one of the major components of marine sediments, in the present study, an investigation has been made to study methane hydrate stability and kinetics in the presence of CaCO3 and MgCO3. Effect of the presence of carbonates on the solubility of methane in the system has also been examined as it directly affects the hydrate formation process. It has been observed that in presence of CaCO3 and MgCO3, the hydrate formation is inhibited. Comparative studies have also been done in the presence of artificial seawater to consider the effect of presence of different salts. Mole consumption of methane gas during hydrate formation in different carbonate samples was measured using real gas equation and found to be minimum in CaCO3 in seawater sample due to the combined effect of the presence of CaCO3 and different salts of seawater. An increase in nucleation and induction time was also observed demonstrating the inhibition of hydrate formation in the presence of these components. Further, the decrease in hydrate formation rate also confirmed the inhibition effect of CaCO3 and MgCO3 on hydrate formation.
Perceptions of healthcare accessibility and medical mistrust among Black women living with HIV in the USA

description:
Black women living with HIV in the USA frequently endure structural racism, racial biases and discrimination in healthcare that affect their access to care. To explore their experiences in healthcare settings as they relate to HIV-treatment accessibility and medical mistrust we used intersectionality and structural intersectionality as guiding frameworks. Four focus groups were conducted with 20 low-income Black women living with HIV in a large urban region. Using thematic analysis, we identified four themes: (1) multilevel stigma and discrimination; (2) medical mistrust of providers across multiple settings; (3) varying responses to stigma, discrimination, and medical mistrust; and (4) preferences for patient-provider relationships. Participants described how medical providers, nurses and other healthcare staff perpetuated negative treatment, including multiple forms of discrimination and stigmatisation based on their HIV diagnosis, race, class and gender. The stigma, discrimination and resulting mistrust experienced often caused hurt feelings and decisions to disengage from treatment or remain with providers while feeling unwelcome. Participants described the strong desire to feel seen, supported and validated by healthcare providers. Narratives reveal that feelings of being discriminated against can cultivate mistrust not only towards doctors, but other provider types and settings. Findings can inform care models for low-income Black women living with HIV.

description: This report with the title “Project Website” has been elaborated as a deliverable (D6.1) in the framework of the VIBES project, presenting the website of the project, as it was created within the first months of VIBES.

The VIBES project, funded by the Bio-Based Industries Joint Undertaking under the European Union’s Horizon 2020 Research and Innovation programme, aims to develop and demonstrate a new, greener, cost-efficient, and non-toxic recycling technology solution that resolves the end-of-life issues of thermoset composite materials.

The VIBES website (www.vibesproject.eu) serves as a platform for the communication and dissemination management of the project. It gathers the latest news, publications, events, external links, and social networks of VIBES to disseminate them among the targeted audience. Besides, it helps to create synergies with other projects and initiatives dealing with the same issues.

Spectroscopic confirmation of the low-latitude object FSR 1716 as an old globular cluster

description: Star clusters are invaluable tracers of the Galactic components and the discovery and characterization of low-mass stellar systems can be used to appraise their prevailing disruption mechanisms and time scales. However, owing to the significant foreground contamination, high extinction, and still uncharted interfaces of the underlying Milky Way components, objects at low Galactic latitudes are notoriously difficult to characterize. Here, we present the first spectroscopic campaign to identify the chemodynamical properties of the low-latitude star cluster FSR 1716. While its photometric age and distance are far from settled, the presence of RR Lyrae variables indicates a rather old cluster variety. Using medium-resolution (R$\sim$10600) calcium triplet (CaT) spectroscopy obtained with the wide-field multi-fibre AAOmega instrument, we identified six member candidates with a mean velocity of $-30$ km s$^{-1}$ and a velocity dispersion of 2.5$\pm$0.9 km s$^{-1}$. The latter value implies a dynamic mass of $\sim$1.3$\times$10$^4$ M$_{\odot}$, typical of a low-mass globular cluster. Combined with our derived CaT metallicity of $-1.38\pm0.20$ dex, this object is finally confirmed as an old, metal-poor globular cluster.

Electroweak Phase Transition in Scale Invariant Standard Model

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

description: In an extension to the scale invariant standard model by two real singlet scalars $s$ and $s'$ in addition to the Higgs field, we investigate the strong first-order electroweak phase transition as a requirement for baryogenesis. This is the minimal extension to the scale invariant standard model with two extra degrees of freedom that possesses the physical Higgs mass of $125$ GeV. The scalar $s'$ being stable because of the $\mathbb Z_2$ discrete symmetry is taken as the dark matter candidate. We then show that the electroweak phase transition is strongly first-order, the dark matter relic density takes the desired value $Ω_{\text{DM}}h^2 \sim 0.11$, and the constraints from direct detection experiments are respected only if $m_{s'}\equiv m_{\text{DM}} \gtrsim 4.5$ TeV. The model also puts a lower bound on the scalon mass, $m_s \gtrsim 200$ GeV.

description: Face recognition is attracting much attention in the society of network multimedia information access. Areas such as network security, content indexing and retrieval, and video compression benefits from face recognition technology because people are the center of attention in a lot of video. Network access control via face recognition not only makes hackers virtually impossible to steal one's password, but also increases the user-friendliness in human-computer interaction. The data in face images are distributed in a complex manner due to the variation of light intensity, facial expression and pose. In this paper the Kernel Principal Component Analysis (KPCA) is used to recognize the faces. A Gaussian model of skin segmentation method is applied here to exclude the global features such as beard, eyebrow, moustache, etc. both training and test images are randomly selected from four different data bases to improve the training. The experimental results show that the proposed framework is efficient for recognizing the humanfaces.

description: We derive analytic approximations for the neutrino luminosities and the heat capacities of neutron stars with isothernal nucleon cores as functions of the mass and radius of stars. The neutrino luminosities are approximated for the three basic neutrino emission mechanisms, and the heat capacities for the five basic combinations of the partial heat capacities. The approximations are valid for for a wide class of equations of state of dense nucleonmatter. The results significantly simplify the theoretical interpretation of observations of cooling neutron stars as well as of quasistationary thermal states of neutron stars in X-ray transients. For illustration, we present an analysis of the neutrino cooling functions of nine isolated neutron stars taking into account the effects of their magnetic fields and of the presence of light elements in their heat blanketing envelopes. These results allow one to investigate the superfluid properties of neutron star cores.

description: The simultaneous creation of multiple electron-positron pairs by localized strong electric fields is studied by utilizing a time- and space-resolved quantum field theory approach. It is demonstrated that the number of simultaneously created pairs equals the number of the potential's supercritical quasibound states in the Dirac sea. This means it can be controlled by tuning the potential parameters. Furthermore, the energy of the created particles corresponds to the energy of the supercritical quasibound states. The simultaneously created electrons and positrons are statistically correlated, which is reflected in the spatial distribution and the momentum distribution of these particles and antiparticles.
