description: Metasurfaces have been investigated and its numerous exotic functionalities and the potentials to arbitrarily control of the electromagnetic fields have been extensively explored. However, only limited types of metasurface have finally entered into real products. Here, we introduce a concept of a metasurface-based smart table for wirelessly charging portable devices and report its first prototype. The proposed metasurface can efficiently transform evanescent fields into propagating waves which significantly improves the near field coupling to charge a receiving device arbitrarily placed on its surface wirelessly through magnetic resonance coupling. In this way, power transfer efficiency of 80$\%$ is experimentally obtained when the receiver is placed at any distances from the transmitter. The proposed concept enables a variety of important applications in the fields of consumer electronics, electric automobiles, implanted medical devices, etc. The further developed metasurface-based smart table may serve as an ultimate 2-dimensional platform and support charging multiple receivers.

description: We study the properties of the q-state frustrated bond percolation model by a Monte Carlo "bond flip" dynamics, using an algorithm originally devised by Sweeny and suitably modified to treat the presence of frustration. We analyze the percolation transition of the model, and find that it falls in the universality class of the q/2-state ferromagnetic Potts model. We then investigate the bond flip dynamics of the model, and find that for temperatures lower than the percolation transition Tp the relaxation functions show a two step decay, reminiscent of the relaxation of glass forming liquids. The long time decay (alpha-relaxation) is well fitted for T

description: We describe a family of quantum error-correcting codes which generalize both the quantum hypergraph-product (QHP) codes by Tillich and Zémor, and all families of toric codes on $m$-dimensional hypercubic lattices. Similar to the latter, our codes form $m$-complexes ${\cal K}_m$, with $m\ge2$. These are defined recursively, with ${\cal K}_m$ obtained as a tensor product of a complex ${\cal K}_{m-1}$ with a $1$-complex parameterized by a binary matrix. Parameters of the constructed codes are given explicitly in terms of those of binary codes associated with the matrices used in the construction.

description: The axial-vector coupling constant in nuclear medium is systematically studied using chiral perturbation theory. For normal nuclear matter, the first non-trivial corrections are estimated based on the independent particle approximation taking into account nuclear correlations in nuclear medium. The one-pion-exchange (OPE) two-body interactions turn out to enhance the coupling constant by $δg_A/g_A\simeq (0.09 \sim 0.15)$. The role of the four-nucleon contact interaction, whose low-energy constants are yet to be determined, is analyzed in connection with the empirical quenching factor of $δg_A/g_A\simeq -0.2$ in the presence of the nuclear short-range correlation. Conventional approaches are discussed in the light of our result.

Εξετάζεται ο τρόπος με τον οποίο οι ιστορικοί της περιόδου, Ιωάννης Κίνναμος και Νικήτας Χωνιάτης, όπως και οι ρήτορες της κομνήνειας αυλής αντιμετώπιζαν τους ηγεμόνες των Σέρβων και τις αποσχιστικές τους τάσεις. Οι Σέρβοι ηγεμόνες φέρουν όλα τα χαρακτηριστικά του βαρβάρου, όπως το παράσπονδον, το ανόητο, τη δειλία και, κυρίως, την αλαζονεία. Από αυτή την εικόνα απουσιάζουν τα θετικά χαρακτηριστικά, καθώς οι Σέρβοι της περιόδου επιχειρούσαν συνεχώς την απομάκρυνσή τους από τη βυζαντινή σφαίρα επιρροής. Η αλαζονική συμπεριφορά των Σέρβων, όπως θεωρούσαν οι Βυζαντινοί, δεν ήταν δυνατόν να μείνει ατιμώρητη. Ο Μανουήλ πέτυχε να ανατρέψει κάθε αποσχιστική απόπειρα και να εξυμνηθεί από τους βυζαντινούς συγγραφείς, ενώ, συγχρόνως, οι αχάριστοι Σέρβοι λοιδορούνται για τις προσπάθειες αποδέσμευσης από την βυζαντινή κυριαρχία.

description: Single-particle dynamics of a spin-orbit-coupled Bose-Einstein condensate has recently been investigated in experiments that explore the physics of Landau-Zener tunneling and of the Zitterbewegung. In this paper, we study the influence of a nonlinearity due to interactions on these dynamics and show that the dispersion relation develops interesting loop strucures. The atoms can move along the nonlinear dispersion curve in the presence of a weak acceleration force and we show that the loops lead to straightforward nonlinear Landau-Zener tunneling. However, we find that for the Zitterbewegung, induced by a sudden quench in the spin-orbit coupling parameters, the nonlinear dispersion is irrelevant.

description: Facing the challenge of e-commerce, people assume that brick and mortar retail is in trouble. However, unlike other sectors, the grocery industry is booming. Even though more shopping channels are available, more than 95% of people still purchase groceries in physical stores. While new trends of grocery shopping are emerging--such as the transition of household shopping from a matriarchal to a democratic process,and customers’ inclination in emphasizing experience over price--shoppers’ needs are changing andcannot be simply satisfied within a traditional retail context.
To understand grocery shoppers’ demands and pain points, I conducted a series of research explorations, which includes research survey, interviews, user shadowing, observation, user-testing and prototyping. Through synthesizing the main learnings, I found five main design opportunities in this area--making grocery shopping more efficient, ameliorating shoppers’ mental load, integrating fragmented online and offline information, exploring more intuitive search and input method, and connecting the grocery store with community.
The solution I present here is a shopping assistant platform called LUMI.It provides a holistic shopping experience for users while connecting the pre-shopping, in-store and after shopping scenarios. For the pre-shopping preparation,an AI assistant enables users to easily create shopping lists. While shopping in a store, real-time AR display and filters help shoppers make better decisions. After leaving the store, people can get grocery delivery from their neighbors by using LUMI. Also, they can share their review sand recipes with their friends. With LUMI, the gap between online and offline shopping will be merged and customers can better enjoy their grocery shopping.

description: No abstracts are to be cited without prior reference to the author.We present a novel statistical method to (i) predict the spatial presence/absence pattern of seaspawning whitefish larvae in the Gulf of Bothnia (GoB), Baltic Sea and (ii) identify the environmental variables that best describe the presence/absence. A generalized Gaussian process (GP) model with additive spatial and non‐linear predictor components is constructed to model the data. A full Bayesian analysis is conducted and the probability of the presence of larval whitefish is predicted for the entire shoreline of the GoB in a 300‐m resolution. The predictors comprise various geoprocessed environmental variables. The importance of the environmental variables to the predictions are examined with an average predictive comparison technique. The data comprise 575 sampling stations located to the Finnish and Swedish shorelines of the GoB. Larval data are collected with beach‐seine and a Gulf Olympia sampler. Results reveal that the most important variables are depth, shore and bottom profile, distance to sandy and shallow shore (20‐m contour line), and the length of ice in winter. The GP is a non‐linear model capable of modelling interactions between explanatory variables and the results indicate that the predictive effects of environmental variables are non‐linear and contain interactions. The additive GP model can be used to construct a spatial predictive map that indicates the most important early stage larval areas of sea‐spawning whitefish in the GoB.

Slav. 3/N) In this paper is presented the Glagolitic Psalter of Demetrius (Ol'tar'nik) No 3/N. This remarkable manuscript of the New Series of Slavic manuscripts of St. Catherine’s Monastery on Mount Sinai has great interest for Old Slavic language and literature. Author of Glagolitic notes and trilingual alphabet was monk Dimitri. The Glagolitic Alphabet is third in a row (first is the Greek and second the Latin one). Although a proportion of the letters from all three alphabets has been destroyed, due to the deterioration of the manuscript, the part that survived allows us to make certain estimates and to move on to interesting observations. The author of the paper compares the Glagolitic alphabet of monk Dimitri with the famous Bulgarian monk Hrabar "O pismeneh" and identifies significant proportions and interesting differences.

description: Giant radio relics in the outskirts of galaxy clusters are known to be lit up by the relativistic electrons produced via diffusive shock acceleration (DSA) in shocks with low sonic Mach numbers, $M_{\rm s}\lesssim3$. The particle acceleration at these collisionless shocks critically depends on the kinetic plasma processes that govern the injection to DSA. Here, we study the preacceleration of suprathermal electrons in weak, quasi-perpendicular ($Q_\perp$) shocks in the hot, high-$β$ ($β= P_{\rm gas}/P_{\rm B}$) intracluster medium (ICM) through two-dimensional particle-in-cell simulations. \citet{guo2014a,guo2014b} showed that in high-$β$ $Q_\perp$-shocks, some of incoming electrons could be reflected upstream and gain energy via shock drift acceleration (SDA). The temperature anisotropy due to the SDA-energized electrons then induces the electron firehose instability (EFI), and oblique waves are generated, leading to a Fermi-like process and multiple cycles of SDA in the preshock region. We find that such electron preacceleration is effective only in shocks above a critical Mach number $M_{\rm ef}^*\approx2.3$. This means that in ICM plasmas, $Q_\perp$-shocks with $M_{\rm s}\lesssim2.3$ may not efficiently accelerate electrons. We also find that even in $Q_\perp$-shocks with $M_{\rm s}\gtrsim2.3$, electrons may not reach high enough energies to be injected to the full Fermi-I process of DSA, because long-wavelength waves are not developed via the EFI alone. Our results indicate that additional electron preaccelerations are required for DSA in ICM shocks, and the presence of fossil relativistic electrons in the shock upstream region may be necessary to explain observed radio relics.

description: Waveguide bends are essential structures for designing an integrated optical waveguide modulator (IOWM). However, reducing bending loss for strip and slot waveguide bends and obtaining a small increment of footprint size by bending the radius are challenging issues. We aim to evaluate whether using strip waveguides with an adiabatic bend reduces the bending loss and to obtain a specific length suitable for a V-shaped mode converter with a small increment of footprint size in the IOWM. Furthermore, a new 180-deg-bend structure for slot waveguides, to reduce bending loss, is investigated. The results of reducing bending radius (R) with a large coverage angle (αc) for strip waveguide bends revealed a low bending loss and simultaneously a reduction of the footprint size in the IOWM. For the 180-deg slot waveguide bend, both the bending and coupling losses were reduced by optimizing the taper and distance offset, which enhanced transmission power efficiency. We validated the feasibility and efficiency of the proposed bending strip and slot structures in IOWM, which is important for integrated optical applications.

description: Jarosite family compounds, KFe_3(OH)_6(SO_4)_2, (abbreviate Fe jarosite), and KCr_3(OH)_6(SO_4)_2, (Cr jarosite), are typical examples of the Heisenberg antiferromagnet on the kagome lattice and have been investigated by means of magnetization and NMR experiments. The susceptibility of Cr jarosite deviates from Curie-Weiss law due to the short-range spin correlation below about 150 K and shows the magnetic transition at 4.2 K, while Fe jarosite has the transition at 65 K. The susceptibility data fit well with the calculated one on the high temperature expansion for the Heisenberg antiferromagnet on the kagome lattice. The values of exchange interaction of Cr jarosite and Fe jarosite are derived to be J_Cr = 4.9 K and J_Fe = 23 K, respectively. The 1H-NMR spectra of Fe jarosite suggest that the ordered spin structure is the q = 0 type with positive chirality of the 120 degrees configuration. The transition is caused by a weak single-ion type anisotropy. The spin-lattice relaxation rate, 1/T_1, of Fe jarosite in the ordered phase decreases sharply with lowering the temperature and can be well explained by the two-magnon process of spin wave with the anisotropy.

description: Many people have pets that they consider to be family. Often, owners find themselves experiencing difficulties in coordinating health care for their pets because of the time investment, required knowledge, and responsibilities. There is a major gap in understanding between an owner and their pet(s), which only gets wider when the owners are away from their pets. This thesis project explores opportunities for an Internet of Things (IoT) approach to close this gap. It aims to create an ecology of digital tools for integrated and informed pet care over physical distance. Based on identified design opportunities, this project proposes the concept of SnapPet, a smart care system consisting of integrated tools in support of remote care activities for their pets.

description: The holy mission of the missionaries, Cyril and Methodius from Thessaloniki to Central Europe in the 9th century constituted a prominent event for the whole of the Slavic world since it profoundly affected the cultural and social formation of its existence. The mission introduced new letters and set the foundations of its culture and education. The Slaves of the south in the mid of the 20th century broached and processed the political notion of “Υugoslavism” a political term which, although it appeared at first to have an ecumenical and supranational character, when based on the historical events, it failed to keep united those who believed in it. This article studies the positive or negative relationships that developed between the two poles of the Slavic world.

The classical distribution is also shown to match smoothly onto the conventional pQCD mini-jet distribution at a scale characteristic of the initial parton transverse density of the system. The atomic number and energy dependence of that scale is computed from available structure function information. The limits of applicability of the classical Yang-Mills description of nuclear collisions at RHIC and LHC energies are discussed.

description: No abstracts are to be cited without prior reference to the author.The results of a study on the development of efficient and reliable acoustic techniques for the classification and monitoring of Baltic seabed habitats are presented. The comprehensive acoustic, geological, and biological investigations were performed in several areas of size up to 10 × 20 km and 220 × 1 km (narrow euphotic zone) located in the southern Baltic Sea, characterized by diversified types of sediments, geomorphological forms, and benthic habitats. We used multibeam and single‐beam echosounders, sidescan sonar, a sub‐bottom profiler, and a van Veen sediment sampler. Such an extensive data collection needs an efficient and fast seabed classification system, which was created and tested during this research. The basis of the system is a parametric approach to acoustic registrations. Computed spectral, wavelet, statistical, and fractal features of echo signals were the input to fuzzy clustering classification and neural network classification algorithms, which produced maps containing morphologically classified seabed areas. All of the seabed segmentation schemes have many promising features which allow them to be applied to the extraction of morphological forms of seabed and habitats. The correctness of the method was verified by the results of underwater video recordings conducted from an underwater vehicle, sedimentological analyses, and biological samples taken in situ.

description: Particle creation during inflation is considered. It could be important for species whose interaction is of gravitational strength or weaker. A complete but economical formalism is given for spin-zero and spin-half particles, and the particle abundance is estimated on the assumption that the particle mass in the early universe is of order the Hubble parameter $H$. It is roughly the same for both spins, and it is argued that the same estimate should hold for higher spin particles in particular the gravitino. The abundance is bigger than that from the usual particle collision mechanism if the inflationary energy scale is of order $10^{16} GeV$, but not if it is much lower.

description: We present a theory and accompanying importance sampling method for computing rate constants in spatially inhomogenious systems. Using the relationship between rate constants and path space partition functions, we illustrate that the relative change in the rate of a rare event through space is isomorphic to the calculation of a free energy difference, albeit in a trajectory ensemble. Like equilibrium free energies, relative rate constants can be estimated by importance sampling. An extension to transition path sampling is proposed that combines biased path ensembles and weighted histogram analysis to accomplish this estimate. We show that rate constants can also be decomposed into different contributions, including relative changes in stability, barrier height and flux. This decomposition provides a means of interpretation and insight into rare processes in complex environments. We verify these ideas with a simple model of diffusion with spatially varying diffusivity and illustrate their utility in an atomistic model of ion pair dissociation near an electrochemical interface.

description: No abstracts are to be cited without prior reference to the author.The relationship between the distribution of benthic marine fauna and different aspects of the physical environment has been a key topic of research for many years. The nature of seabed sediments is one of the main drivers determining benthic community composition, so the way in which sediment deposits are classified is of fundamental importance in biotope classification and predictive mapping. The EUNIS (European Nature Information System) habitat classification scheme splits sediment deposits into four broad classes, namely “mud and sandy mud”, “sand and muddy sand”, “coarse”, and “mixed” sediment. However, there is no practical guidance supplied with the EUNIS scheme on how these sediment categories should be applied to empirical or modelled sediment data, leading to inconsistent biotope designations. A segmentation of the Folk triangle, which provides a useful translation between existing Folk maps and EUNIS habitats, was developed in the MESH project (Mapping European Seabed Habitats). However, this categorization has been demonstrated to result in a poor match between modelled and observed biotopes. Many of the difficulties in using this classification scheme have arisen because it, counterintuitively, places some sand habitats into the coarse sediment category and because the splits between “mud” and “muddy sand” and between “sand” and “muddy sand” have not been defined. During the course of two regional seabed‐mapping projects in the UK we investigated alternative ways of segmenting the Folk triangle and propose a refined segmentation that better reflects the relationship between sediment class and species distributions and which facilitates habitat modelling using the EUNIS habitat classification scheme.

description: This paper proposes a framework based on deep convolutional neural networks (CNNs) for automatic heart sound classification using short-segments of individual heart beats. We design a 1D-CNN that directly learns features from raw heart-sound signals, and a 2D-CNN that takes inputs of two- dimensional time-frequency feature maps based on Mel-frequency cepstral coefficients (MFCC). We further develop a time-frequency CNN ensemble (TF-ECNN) combining the 1D-CNN and 2D-CNN based on score-level fusion of the class probabilities. On the large PhysioNet CinC challenge 2016 database, the proposed CNN models outperformed traditional classifiers based on support vector machine and hidden Markov models with various hand-crafted time- and frequency-domain features.

description: We examine scaling in two-dimensional simulations of dendritic growth at low undercooling, as well as in three-dimensional pivalic acid dendrites grown on NASA's USMP-4 Isothermal Dendritic Growth Experiment. We report new results on self-similar evolution in both the experiments and simulations. We find that the time dependent scaling of our low undercooling simulations displays a cross-over scaling from a regime different than that characterizing Laplacian growth to steady-state growth.

description: In a very interesting paper, Hod has proven that the equatorial null circular geodesic provides the extreme orbital period to circle a kerr black hole, which is closely related to the Fermat's principle. In the present paper, we extend the discussion to kerr black holes with scalar field hair. We show that the circle with the extreme orbital period is still identical to the null circular geodesic. Our analysis also implies that the Hod's theorem may be a general property in any axially symmetric spacetime with reflection symmetry on the equatorial plane.

description: No abstracts are to be cited without prior reference to the author.There is a growing pressure on coastal ecosystems from climate change and a diverse range of human activities. To develop effective marine spatial plans and achieve knowledge‐based management decisions, managers and policy‐makers need information (i.e. maps) on where different habitats are found. This information has been lacking in the marine environment in Norway for years, but in 2003, a national programme for mapping and monitoring of marine biodiversity started sampling and integrating data on habitat and species distribution. The Norwegian coast is long and complex, and mapping all of the habitats in all areas is an enormous task. Consequently, spatial predictive modelling based on statistical analyses of field‐sampled data was developed as a tool. The methodology includes collaboration between physical oceanographers, marine ecologists and geologists, statisticians, and modellers, including GIS experts. This presentation will introduce the methods developed, the habitats modelled, and the lessons learned from doing such modelling at the national scale.
Gapless spin excitations in superconducting La$_{2-x}$Ca$_{1+x}$Cu$_{2}$O$_{6}$ with $T_c$ up to 55 K

description: We report inelastic neutron scattering on single crystals of the bilayer cuprate family La$_{2-x}$Ca$_{1+x}$Cu$_{2}$O$_{6+δ}$, including two crystals made superconducting (transitions at 45 and 55 K) by high-pressure annealing in an oxygen-containing atmosphere. The magnetic excitations in the non-superconducting crystal have a similar temperature-dependence as those in weakly hole-doped cuprates. In the superconducting crystals, there is a near-uniform suppression of the magnetic spectral weight with increasing temperature; in particular, there are no signs of a spin gap or "resonance" peak. This is different from the temperature dependence seen in many optimally-doped cuprates but similar to the behavior seen in certain underdoped cuprates. We discuss the possible connection with pair-density-wave superconductivity.

description: We report on the observation of spatially-localized excitations in a ladder of small Josephson junctions. The excitations are whirling states which persist under a spatially-homogeneous force due to the bias current. These states of the ladder are visualized using a low temperature scanning laser microscopy. We also compute breather solutions with high accuracy in corresponding model equations. The stability analysis of these solutions is used to interpret the measured patterns in the I-V characteristics.

description: No abstracts are to be cited without prior reference to the author.Environmental variables are increasingly used as indirect surrogates for mapping biodiversity patterns for planning and management applications because species survey data are scant, especially in the marine realm. However, environmental variables are measured on arbitrary scales unlikely to be directly relevant to biology. To make the connection, knowledge of the relationships between biological patterns and environmental variables is essential. We quantified these relationships by applying a novel analysis approach, “Gradient Forest”, to examine the extent to which these variables predicted biological patterns and to explore the shapes and magnitude of multiple species responses representing patterns of biodiversity composition change along gradients of >30 environmental variables. These responses were compared for trawl, benthic sled, and grab surveys from three mesoscale regions: tropical Australia, deep Gulf of Mexico, and temperate Gulf of Maine. Typically, the environmental variables predicted an average of 13–35% of the variation in biological patterns. Important predictors differed among regions and biota, and included depth, salinity, temperature, sediment composition, and current stress. The shapes of responses also differed and were non‐linear, often with thresholds indicative of step changes in composition. Within regions, Gradient Forest allowed integration of responses across multiple disparate surveys that used different sampling devices. This information contributes to our understanding of the environmental drivers of patterns of beta diversity at mesoscales, and ʺbiologically informedʺ transformations of the more readily available environmental data can be applied to provide predictive maps of patterns of biodiversity composition in a way that better reflects biological patterns than uninformed environmental variables alone.

Calculation of $g_{πNS_{11}}$ and $g_{ηNS_{11}}$ Couplings in QCD Sum Rules

Publisher: name: arXiv
Year: 1997
Subjects: subject: Nuclear Theory (nucl-th)

subject: FOS: Physical sciences

description: We calculate the coupling constants, $g_{πNS_{11}}$ and $g_{ηNS_{11}}, using QCD sum rules in the presence of an external meson field. A covariant derivative is introduced within the S_{11} interpolating field so that in the nonrelativistic limit the field dominantly reduces to two quarks in the s-wave state and one quark in the p-wave state. Our result for the couplings obtained by further making use of the soft-meson theorem qualitatively agrees with its phenomenological value extracted from the S_{11}(1535) decay width. The prediction for the couplings however depend on the value of quark-gluon condensate, $< {\bar q} g_s σ\cdot {\cal G} q >$, which is also important in the calculation of the S_{11}(1535) mass itself within the sum rule approach.

description: We derive the Ginzburg-Landau theory of unconventional singlet superconductors in the presence of a Zeeman field and impurities, in order to examine the resulting Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) phases. We show that the behavior of the FFLO phases in unconventional superconductors in the presence of impurities is qualitatively different from that found for s-wave superconductors.

Scale Invariance vs. Conformal Invariance: Holographic Two-Point Functions in Horndeski Gravity

description: We consider Einstein-Horndeski gravity with a negative bare constant as a holographic model to investigate whether a scale invariant quantum field theory can exist without the full conformal invariance. Einstein-Horndeski gravity can admit two different AdS vacua. One is conformal, and the holographic two-point functions of the boundary energy-momentum tensor are the same as the ones obtained in Einstein gravity. The other AdS vacuum, which arises at some critical point of the coupling constants, preserves the scale invariance but not the special conformal invariance due to the logarithmic radial dependence of the Horndeski scalar. In addition to the transverse and traceless graviton modes, the theory admits an additional trace/scalar mode in the scale invariant vacuum. We obtain the two-point functions of the corresponding boundary operators. We find that the trace/scalar mode gives rise to an non-vanishing two-point function, which distinguishes the scale invariant theory from the conformal theory. The two-point function vanishes in $d=2$, where the full conformal symmetry is restored. Our results indicate the strongly coupled scale invariant unitary quantum field theory may exist in $d\ge 3$ without the full conformal symmetry. The operator that is dual to the bulk trace/scalar mode however violates the dominant energy condition.
