description: We investigated the precise crystal structures and electronic states in a quasi-two-dimensional molecular conductor $α$-(BETS)$_2$I$_3$ at ambient pressure. The electronic resistivity of this molecular solid shows metal-to-insulator (MI) crossover at $T_{MI}$=50 K. Our x-ray diffraction and $^{13}$C nuclear magnetic resonance experiments revealed that $α$-(BETS)$_2$I$_3$ maintains the inversion symmetry below $T_{MI}$. First-principles calculations found a pair of anisotropic Dirac cones at a general k-point, with the degenerate contact points at the Fermi level. The origin of the insulating state in this system is a small energy gap of ~2 meV opened by the spin-orbit interaction. The Z$_2$ topological invariants indicate that this system is a weak topological insulator. Our results suggest that $α$-(BETS)$_2$I$_3$ is a promising material for studying the bulk Dirac electron system in two dimensions.

Physical Unitarity for Massive Non-abelian Gauge Theories in the Landau Gauge: Stueckelberg and Higgs

description: We discuss the problem of unitarity for Yang-Mills theory in the Landau gauge with a mass term a la Stueckelberg. We assume that the theory (non-renormalizable) makes sense in some subtraction scheme (in particular the Slavnov-Taylor identities should be respected!) and we devote the paper to the study of the space of the unphysical modes. We find that the theory is unitary only under the hypothesis that the 1-PI two-point function of the vector mesons has no poles (at p^2=0). This normalization condition might be rather crucial in the very definition of the theory. With all these provisos the theory is unitary. The proof of unitarity is given both in a form that allows a direct transcription in terms of Feynman amplitudes (cutting rules) and in the operatorial form. The same arguments and conclusions apply verbatim to the case of non-abelian gauge theories where the mass of the vector meson is generated via Higgs mechanism. To the best of our knowledge, there is no mention in the literature on the necessary condition implied by physical unitarity.

Pulsar Kicks Induced by Spin Flavor Oscillations of Neutrinos in Gravitational Fields
Creators: name: Lambiase, G.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The origin of pulsar kicks is reviewed in the framework of the spin-flip conversion of neutrinos propagating in the gravitational field of a magnetized protoneutron star. We find that for a mass in rotation with angular velocity ${\bbox ω}$, the spin connections entering in the Dirac equation give rise to the coupling term ${\bbox ω}\cdot {\bf p}$, being ${\bf p}$ the neutrino momentum. Such a coupling can be responsible of pulsar kicks owing to the neutrino emission asymmetry generated by the relative orientation of ${\bf p}$ with respect to ${\bbox ω}$. For our estimations, the large non standard neutrino magnetic momentum, $μ_ν\lesssim 10^{-11}μ_B$, is considered.

Between authority and autonomy : critically engaged interpretation in the art museum
Creators: name: Meszaros, Cheryl
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation proceeds from the premise that the art museum has a singularly important responsibility to carry out in a democratic society. I argue that the museum's task is "to make art public," that is, to move art—and the interpretive apparatus that support and maintain it—from the relatively private spheres of the artist's studio and the academy into the public realm. In a post modern milieu, where art consists just as much of its interpretability as it does in the physicality of the object, the museum is faced with the even more difficult task of making the art object as the range, depth, and breadth of its interpretive repertoires available to the public. I suggest that the museum can take up this public responsibility by creating self-consciously critical spaces of interpretation for the public. In order to create these spaces, the museum must embark upon a critique of the discursive coordinates that have privileged a pedagogy of display and that have installed schooling as the primary interface between art and the public. In so doing the museum can begin to articulate the spaces between its own interpretive authority and the equally undeniable autonomy of the public to make whatever meaning they will in the face of a pedagogy of display. I propose that it is from the spaces in between notions of authorial truth and excessive relativism that the museum can begin to pay heed to the kinds of interpretive repertoires that are currently embedded in its practices and from there begin to develop critically engaged sites of interpretation for the public. I put forward the concepts of "being-singular-plural" and "co-appearance" as productive ways to re-imagine how critically engaged forms of interpretation in the art museum can work intentionally and productively from the spaces between the poles of authority and autonomy.

description: Le projet DEFIPEL s’est déroulé entre septembre 2019 et juillet 2024. Il s’agit d’un projet de recherche ayant pour but d’analyser la structure et la dynamique de la filière française des petits pélagiques, en intégrant les composantes habitat, ressource (sardine et anchois principalement), pêcheries et filière aval avec notamment l’industrie de la conserve. C’est un projet national qui s’est intéressé aux 3 façades maritimes métropolitaines : la Manche, le Golfe du Lion, et le Golfe de Gascogne, avec toutefois un effort plus important sur ce dernier. L’implication de chercheurs de différentes disciplines (océanographie, écologie, halieutique, économie) et des différents acteurs de la filière (12 partenaires représentant les pêcheurs, l’industrie de la conserve, les gestionnaires de l’espace maritime au travers d’un parc marin) a permis de couvrir l’ensemble des thématiques permettant d’obtenir une vision intégrée du socio-écosystème et de ses enjeux. Le projet a notamment révélé les interactions entre les compartiments du système et offert des pistes de compréhension de la diminution récente de condition des petits pélagiques. Au delà d’avoir amélioré la connaissance et la compréhension de cette filière, le projet avait pour but de proposer des outils d’aide à la décision novateurs pour la gestion intégrée de la filière. C’est ce que nous avons réalisé tout d’abord au travers de l’élaboration d’un tableau de bord présentant un suivi de l’évolution temporelle de nombreuses variables représentatives des différentes composantes du système entre 2000 et 2020. Il est associé à un système d’alerte basé sur des détections de changement de régime ou de dérive dans ces séries temporelles permettant d’anticiper les problèmes. Afin d’envisager des solutions aux crises en cours, nous avons également travaillé à l’élaboration de scénarios narratifs d’évolution de la filière à 10 ans (souhaitable, probable, non-souhaitable), co-construits avec l’ensemble des acteurs. Ils ont été dans un second temps traduits et simulés par un modèle numérique de la pêcherie des petits pélagiques du Golfe de Gascogne, afin d’évaluer de manière quantitative les trajectoires possibles des indicateurs et l’atteinte des objectifs de durabilité pour la pêcherie.

description: Dementia is one of the most significant medical and social problems of modern society, which is caused by a steady increase in morbidity associated with an increase in the life expectancy of the population. According to the World Health Organization, there are more than 55 million people with dementia worldwide, and that number could triple by 2050. In these conditions, the search for effective therapies that can not only alleviate the symptoms of the disease, but also influence its pathogenetic mechanisms, becomes particularly relevant.

description: We study the nucleon and diquarks in a non-local Nambu-Jona-Lasinio model. For certain parameters the model exhibits quark confinement, in the form of a propagator without real poles. After truncation of the two-body channels to the scalar and axial-vector diquarks, a relativistic Faddeev equation for nucleon bound states is solved in the covariant diquark-quark picture. The dependence of the nucleon mass on diquark masses is studied in detail. We find parameters that lead to a simultaneous reasonable description of pions and nucleons. Both the diquarks contribute attractively to the nucleon mass. Axial-vector diquark correlations are seen to be important, especially in the confining phase of the model. We study the possible implications of quark confinement for the description of the diquarks and the nucleon. In particular, we find that it leads to a more compact nucleon.

The equatorial components of this vector were found to be the following: $ω_x = +0.04\pm 0.15$ mas yr$^{-1}$, $ω_y = +0.18\pm 0.12$ mas yr$^{-1}$, and $ω_z = -0.35\pm 0.09$ mas yr$^{-1}$.

description: We model the magnetization of quasi two-dimensional systems with easy perpendicular (z-)axis anisotropy upon change of external magnetic field along z. The model is derived from the Landau-Lifshitz-Gilbert equation for magnetization evolution, written in closed form in terms of the z component of the magnetization only. The model includes--in addition to the external field--magnetic exchange, dipolar interactions and structural disorder. The phase diagram in the disorder/interaction strength plane is presented, and the different qualitative regimes are analyzed. The results compare very well with observed experimental hysteresis loops and spatial magnetization patterns, as for instance for the case of Co-Pt multilayers.

description: For the discrete Laguerre operators we compute explicitly the corresponding heat kernels by expressing them with the help of Jacobi polynomials. This enables us to show that the heat semigroup is ultracontractive and to compute the corresponding norms. On the one hand, this helps us to answer basic questions (recurrence, stochastic completeness) regarding the associated Markovian semigroup. On the other hand, we prove the analogs of the Cwiekel-Lieb-Rosenblum and the Bargmann estimates for perturbations of the Laguerre operators, as well as the optimal Hardy inequality.

description: Social capital has been recently held up as a conceptual framework to build a bridge between the diverse disciplines involved in rural development. However, despite its potential and the impressively rapid take-up of the concept by the community of development professionals, it remains an elusive construct. No definition is yet generally accepted and many definitions are in use. Recently, social capital in the form of social networks has gained much attention in rural development theory and empirical research. But social networks or structural components of social capital are a largely missing dimension in income and poverty analysis. Moreover, most research on social capital assumes that it is a uniform entity. Therefore, the effects of different forms of social capital on household outcome are rarely investigated. The objective of this discussion paper is to make the concept of social capital more tangible for empirical research in the area of rural development and to bring more structure into the conceptual framework of social capital. On the basis of an extensive literature review, this work proposes a lean and clear definition of social capital: Social capital is conceived as networks plus resources, (e.g. credit, information). Moreover, social capital is assumed to be not a homogeneous entity. Hence, it is necessary to distinguish different forms of social capital. For analytical purposes, the separation into so-called bonding and bridging capital seems to be most appealing. These two forms of social capital can be operationalized as function of an agent’s so-called weak ties (e.g. acquaintances) and so-called strong ties (e.g. close relatives).

description: We study the pairing of Fermi gases near the scattering resonance of the $\ell\neq 0$ partial wave. Using a model potential which reproduces the actual two-body low energy scattering amplitude, we have obtained an analytic solution of the gap equation. We show that the ground state of $\ell=1$ and $\ell=3$ superfluid are orbital ferromagnets with pairing wavefunctions $Y_{11}$ and $Y_{32}$ respectively. For $\ell=2$, there is a degeneracy between $Y_{22}$ and a "cyclic state". Dipole energy will orient the angular momentum axis. The gap function can be determined by the angular dependence of the momentum distribution of the fermions.

description: Australia has long been a major exporter of the products of broadacre agriculture, a production system well suited to the economic and climatic conditions of the country. According to the conventional wisdom, Australia holds a comparative advantage in these products, among which wheat and livestock products predominate. However, the future validity of this proposition is sensitive to the projected impacts of climate change. This paper develops a framework with which to quantify the future patterns of comparative advantage in broadacre agriculture given the projections of several global climate models. We find empirical support for the conventional wisdom, and note substantial resilience in Australia’s comparative advantage to adverse yield change.

description: Sonoluminescence is a phenomenon involving the transduction of sound into light. The detailed mechanism as well as the energy-focusing potentials are not yet fully explored and understood. So far only optical photons are observed, while emissions in the ultra-violet range are only inferred. By doping the fluorescent dye quinine into water with dilute sulphuric acid, the high energy photons can be converted into the optical photons with slower decay constants. These sonoluminescence and fluorescent emissions were observed in coincidence, and the emitted signals of the two modes can be differentiated by their respective timing profiles. Plans for using this technique as a diagnostic tool to quantitatively study ultra-violet and other high energy emissions in sonoluminescence are discussed.

description: New Zealand houses are cold, damp, and poorly insulated by international standards. Our substandard housing stock has negative effects on health, quality of life, productivity, winter air quality, energy use and transmission. Investment in home energy efficiency is below the socially optimal level due to information asymmetries, bounded rationality and to some degree, non-excludability. Uptake of government grants for insulation has been very low in some communities, especially by owners of private rental properties. This study examines consumer preferences and perceptions of home energy efficiency technologies for residents of the Waikato region. We use a choice experiment approach to determine willingness to pay by owner-occupiers, landlords and tenants. Owner-occupiers are willing to pay significantly more than landlords for all features except for double-glazing. Tenants score their homes lower in terms of warmth and comfort than the landlord, and are willing to pay higher rent for improved insulation. However, the majority of tenants don’t know what insulation their home already has. Solving this information asymmetry problem with home energy ratings may be a more efficient way to increase investment than larger subsidies for landlords.

The bottom-parton scattering process is computed to NLO, and the validity of the bottom-parton approach is established in detail. The light-flavor Drell-Yan cross section is evaluated at NLO as well. The gluon fusion process through a one-loop amplitude is then compared with these two results. We show how a complete sample of events could look, in terms of total cross sections and distributions of the heavy final states.

description: We introduce endogenous investments for increasing conventional and non-conventional oil extraction capacity in the integrated assessment model WITCH. The international price of oil emerges as the Nash equilibrium of a non-cooperative game. When carbon emissions are not constrained, oil is used throughout the century, with unconventional oil taking over conventional oil from mid-century onward. When carbon emissions are constrained, oil consumption drops dramatically and the oil price is lower than in the BaU. Unconventional oil is not extracted. Regional imbalances in the distribution of stabilisation costs are magnified and the oil-exporting countries bear, on average, costs three times larger than in previous estimates.
Templated Dewetting-Alloying of NiCu Bilayers on TiO$_2$ Nanotubes Enables Efficient Noble Metal-Free Photocatalytic $H_2$ Evolution

description: Photocatalytic $H_2$ evolution reactions on pristine TiO$_2$ is characterized by low efficiencies due to trapping and recombination of charge carriers, and due to a sluggish kinetics of electron transfer. Noble metal (mainly Pt, Pd, Au) nanoparticles are typically decorated as cocatalyst on the TiO$_2$ surface to reach reasonable photocatalytic yields. However, owing to the high cost of noble metals, alternative metal cocatalysts are being developed. Here we introduce an approach to fabricate an efficient noble metal free photocatalytic platform for $H_2$ evolution based on alloyed NiCu cocatalytic nanoparticles at the surface of anodic TiO$_2$ nanotube arrays. NiCu bilayers are deposited onto the TiO$_2$ nanotubes by plasma sputtering. A subsequent thermal treatment is carried out that leads to dewetting, that is, owing to surface diffusion the Ni and Cu sputtered layers simultaneously mix with each other and split into NiCu nanoparticles at the nanotube surface. The approach allows for a full control over key features of the alloyed nanoparticles such as their composition, work function and cocatalytic ability towards $H_2$ generation. Dewetted-alloyed cocatalytic nanoparticles composed of equal Ni and Cu amounts not only are significantly more reactive than pure Ni or Cu nanoparticles, but also lead to $H_2$ generation rates that can be comparable to those obtained by conventional noble metal (Pt) decoration of TiO$_2$ nanotube arrays.

description: We present a standard model of financial innovation, in which intermediaries engineer securities with cash flows that investors seek, but modify two assumptions. First, investors (and possibly intermediaries) neglect certain unlikely risks. Second, investors demand securities with safe cash flows. Financial intermediaries cater to these preferences and beliefs by engineering securities perceived to be safe but exposed to neglected risks. Because the risks are neglected, security issuance is excessive. As investors eventually recognize these risks, they fly back to safety of traditional securities and markets become fragile, even without leverage, precisely because the volume of new claims is excessive. Financial innovation can make both investors and intermediaries worse off. The model mimics several facts from recent historical experiences, and points to new avenues for financial reform.

description: We study the long-time asymptotics of a certain class of nonlinear diffusion equations with time-dependent diffusion coefficients which arise, for instance, in the study of transport by randomly fluctuating velocity fields. Our primary goal is to understand the interplay between anomalous diffusion and nonlinearity in determining the long-time behavior of solutions. The analysis employs the renormalization group method to establish the self-similarity and to uncover universality in the way solutions decay to zero.

description: The properties of energy spectrum of excitons in monolayer transition metal dichalcogenides are investigated using a multiband model. In the multiband model we use the excitonic Hamiltonian in the product base of the Dirac single-particle states at the conduction and valence band edges. Following the separation of variables we decouple the corresponding energy eigenvalue system of the first order ODE radial equations rigorously and solve the resulting the second order ODE self-consistently, using the finite difference method, thus we determine the energy eigenvalues of the discrete excitonic spectrum and the corresponding wave functions. We also developed WKB approach to solve the same spectral problem in semiclassical aproximation for the resulting ODE. We compare the results for the energy spectrum and the corresponding eigen-functions forms for WS2 and WSe2 obtained by means of both methods. We also compare our results for the energy spectrum with other theoretical works for excitons, and with available experimental data.
Father pieces

description: The purpose of this autobiographical study is to examine and re-witness the qualitative relationship between father and son. In this study, I initiate a deeper understanding of the stories and events that have been invoked during the process of writing and imaging this self-narrative. This narrative text is a portrayal of events in my life that have been significant in forming my own images of self, masculinity, and the roles and relationships of both fathers and sons. The context of the narrative is situated within the transcript of a phenomenological autobiography that is interwoven with different temporal and archetypal perspectives, academic literature, poetry, autoethnography and various artistic images. The qualitative methodology that is used in this study is an adapted autobiographical method called self-narrative using a fragmented account. Through reading the narrative, the reader participates in remnants of lived experience that function to create a phenomenological impression within the shifting perspectives of father, son and the development of the masculine self-image. Witnessing the narrative and their accompanying images in both their fragments and their totality evokes an experience of embodiment for the reader. The reader can then say that they have shared in what another has experienced and through identification with their own lives, may then say that they recognize, know and understand the phenomenon and the experience. The voices which are invoked are exclusively my own and the images that have been created are impressions of my own lived experiences. Through witnessing and writing about them, my images of self, masculinity, father and son relationships have been brought to light and transformed. This work broadens the dialogue crucial to the understanding of men and their relationships in our world and initiates a deeper examination of the importance of masculine studies.

description: We compare theoretical and simulation results for static and dynamic properties for a model of particles interacting via a spherically symmetric repulsive ramp potential. The model displays anomalies similar to those found in liquid water, namely, expansion upon cooling and an increase of diffusivity upon compression. In particular, we calculate the phase diagram from the simulation and successfully compare it with the phase diagram obtained using the Rogers-Young (RY) closure for the Ornstein-Zernike equation. Both the theoretical and the numerical calculations confirm the presence of a line of isobaric density maxima, and lines of compressibility minima and maxima. Indirect evidence of a liquid-liquid critical point is found. Dynamic properties also show anomalies. Along constant temperature paths, as the density increases, the dynamics alternates several times between slowing down and speeding up, and we associate this behavior with the progressive structuring and de-structuring of the liquid. Finally we confirm that mode coupling theory successfully predicts the non-monotonic behavior of dynamics and the presence of multiple glass phases, providing strong evidence that structure (the only input of mode coupling theory) controls dynamics.

In addition, significant bandwidth renormalizations of the $t_{2g}$ complex have been observed. We show that these discrepancies are due to strong electronic correlations by studying the multi-orbital Hubbard model in the Hartree-Fock and strong-coupling Gutzwiller approximation. The quasiparticle dispersion and the Fermi surface topology obtained in the presence of strong local Coulomb repulsion are in good agreement with experiments.

description: Early prehistoric remains, including a Late Bronze Age or Early Iron Age post-built structure, were discovered during archaeological mitigation works carried out to the north of Townhead Road, Dalston, Cumbria (centred on NY 3677 5020). The groundworks also confirmed the presence of an early field system identified during a preceding magnetometer survey (CFA Archaeology 2013). Later remains associated with medieval ploughing and post-medieval field boundaries, including an earthwork that formed the north-eastern and eastern boundaries of the site, were also recorded.

description: This article looks at two medieval coin hoards discovered in the Wigton and Maryport areas of Cumbria. It examines the contents of both hoards and compares denominations and mints represented with other hoards of similar date in England. It will be seen that both hoards follow a national pattern and there is no variation between hoards deposited in the south of England and the north. The article also puts the hoards in the context of medieval Cumberland.

description: This paper presents the results of an archaeological investigation undertaken by Wardell Armstrong Archaeology on land at Low Crosby, near Carlisle, Cumbria. The work has revealed evidence for medieval activity, utilising small-scale farming practices. The limited evidence revealed suggests that the activity may relate to a farmstead, possibly on the periphery of a larger settlement. Whilst rural settlements are relatively well recorded within the region for this period, very few have produced evidence for associated agricultural practices. Of particular significance was the discovery of a probable corn-drying kiln of medieval date. Whilst other well-preserved corn-drying kilns have been excavated from around the country, very few comparable examples are known from Cumbria and the typological development, construction and use of such features remain poorly understood. In these respects, the site at Low Crosby is a regionally significant discovery. The investigation also highlighted a recurring problem with the dating of archaeological sites as most of the activity was initially assigned to the Romano-British period based upon the retrieval of a modest assemblage of Roman pottery from several features. This date, however, was in direct conflict with the environmental evidence and radiocarbon dating, highlighting the dangers of solely using artefactual evidence as a dating indicator.
Early generations of the Bewley family of Cumberland

description: Sir Edmund Thomas Bewley's book, The Bewleys of Cumberland and their Irish and other Descendants, was published in 1902. It recounted and interpreted a substantial body of research and, having placed the family's origin in Hainault, identified Thomas de Beaulieu, living in Cumberland in the 1330s, as first in the lineage of a family that saw considerable growth between the early sixteenth and late nineteenth century. Early TNA records are now more extensively calendared than in 1902, enabling this paper's author to identify various significant additional references to early members of the family, and to review Sir Edmund's account of the first seven generations in his lineage. Whilst recognising that many familial relationships can only be inferred, the author concludes that the Cumberland family originated locally rather than in Hainault, and that there is also cause to modify its early lineage.
Early Poor Relief in South Westmorland: the Barony of Kendal Poor Law Returns, 1637

description: The 'Old' Poor Law, which continued until 1834, stood as one of the lasting achievements of Tudor governance. In contrast with most of the European continent, where poor relief remained predominantly urban, ad hoc, and unsupported by regular taxation, England had - from Elizabeth's reign onwards - a system of support for the needy which was, at least in theory, regularised and geographically universal.

description: Between March 2012 and February 2013, Oxford Archaeology (OA) North undertook a programme of archaeological works to the north of Albion Street, Whitehaven. These revealed elements of an eighteenth-century soapery, which was converted into a bakery c.1854, and, between 1866 and c.1930, was the site of the Ramsey Bros Phoenix Foundry. Some of the domestic structures surrounding the industrial complex were briefly explored, also. This paper integrates the historical and archaeological data to present a narrative of the site during the eighteenth and nineteenth centuries.
The Barony of Kendal

description: Transactions of the Cumberland & Westmorland Antiquarian & Archaeological Society, 15, 45-56
description: This article has been developed from a guidance paper written for volunteer researchers working on the Victoria County History (VCH) of Cumbria project. The paper outlines the descent of the barony of Kendal from the end of the eleventh century to the present day, and describes how the barony was divided into the Lumley, Richmond, and Marquis fees. This information is intended to inform research into the landownership section of individual VCH township/parish articles, as well as a future article on superior lordship in Cumbria. Material has been drawn from a number of original sources, many of which are available in print. These include the published Calendars of Patent Rolls, Close Rolls, and Inquisitions Post Mortem, as well as Farrer and Curwen's invaluable Records of the Barony of Kendale. The more recent work of Richard Sharpe on the Normans in Cumbria has also helped to shed light on the complex early history of the barony.
Opening 'the blacke booke of oblivion': How Ortelius revealed the Roman North West

description: Ortelius' map of 1590 was ground-breaking in seeking to locate upon a modern outline every place named by classical authors, or listed by Ptolemy, the Antonine Itinerary or the Notitia Dignitatum, as part of a project to do the same not just for Britain, but for the whole Roman world. The research had taken 25 years to complete and had involved detailed work by local scholars, in particular Humphrey Lhuyd and William Camden. Using the places listed in the north-west corner of Ortelius' map, covering the present-day counties of Cumbria and Lancashire, the methodology of these antiquaries is revealed, based initially upon conjecture and perceived similarities to the old names, but over time coming to place more reliance upon the presence of visible archaeological traces or inscriptions. Ortelius' map is contrasted with Camden's less successful map of 1600, an attempt which was not to be repeated for nearly 100 years.

description: Control Flow Graph (CFG) similarity analysis is an essential technique for a variety of security analysis tasks, including malware detection and malware clustering. Even though various algorithms have been developed, existing CFG similarity analysis methods still suffer from limited efficiency, accuracy, and usability. In this paper, we propose a novel fuzzy hashing scheme called topology-aware hashing (TAH) for effective and efficient CFG similarity analysis. Given the CFGs constructed from program binaries, we extract blended n-gram graphical features of the CFGs, encode the graphical features into numeric vectors (called graph signatures), and then measure the graph similarity by comparing the graph signatures. We further employ a fuzzy hashing technique to convert the numeric graph signatures into smaller fixed-size fuzzy hash signatures for efficient similarity calculation. Our comprehensive evaluation demonstrates that TAH is more effective and efficient compared to existing CFG comparison techniques. To demonstrate the applicability of TAH to real-world security analysis tasks, we develop a binary similarity analysis tool based on TAH, and show that it outperforms existing similarity analysis tools while conducting malware clustering.

description: We present a permanent magnetic film atom chip based on perpendicularly magnetized TbGdFeCo films. This chip routinely produces a Bose-Einstein condensate (BEC) of 10^5 87Rb atoms using the magnetic film potential. Fragmentation observed near the film surface provides unique opportunities to study BEC in a disordered potential. We show this potential can be used to simultaneously produce multiple spatially separated condensates. We exploit part of this potential to realize a time-dependent double well system for splitting a condensate.

description: The objective of this work is to provide a mathematical analysis on how a Thoroughbred horse should regulate its speed over the course of a race to optimize performance. Because Thoroughbred horses are not capable of running the whole race at top speed, determining what pace to set and when to unleash the burst of speed is essential. Our model relies on mechanics, energetics (both aerobic and anaerobic) and motor control. It is a system of coupled ordinary differential equations on the velocity, the propulsive force and the anaerobic energy, that leads to an optimal control problem that we solve. In order to identify the parameters meaningful for Thoroughbred horses, we use velocity data on races in Chantilly (France) provided by France Galop, the French governing body of flat horse racing in France. Our numerical simulations of performance optimization then provide the optimal speed along the race, the oxygen uptake evolution in a race, as well as the energy or the propulsive force. It also predicts how the horse has to change its effort and velocity according to the topography (altitude and bending) of the track.
