description: Using the photospheric magnetic and coronal observations of Solar Dynamics Observatory, we studied the build-up and eruption of coronal non-potential magnetic structure in emerging active region (AR) 12673. The velocity field derived from tracked vector-magnetograms indicates persistent shear and converging motions of flux regions about the polarity inversion line (PIL). A major helicity injection occurs during rapid flux emergence consistent with the very fast flux emergence phase. While this helicity flux builds-up the sigmoid by September 4, the helicity injection by the continued shear and converging motions in the later evolution contributes to sigmoid sustenance and its core field twist as a manifestation of the flux rope which erupts after exceeding critical value of twist. Moreover, the total length of sheared PIL segments correlates with the non-neutralized current and maintains a higher value in both the polarity regions as a signature of eruptive capability of the AR according to the flux rope models. The modelled magnetic field qualitatively reproduces the sigmoidal structure capturing major features like twisted core flux as flux rope, and hook-shaped parts connecting at the middle of the PIL. Study of quasi-separatrix-layers reveals that the sheared arcade, enclosing the flux rope, is stressed to a critically stable state and its coronal height becomes doubled from September 4-6. While demonstrating the fast injection of helicity per unit flux as the crucial factor for severe space-weather events, this study explains the formation of the flux rope and recurrent eruptive nature of the AR by the critically stable state of sheared arcade early on September 6.

description: Mineral Accretion Factory is an alternative production system of objects and furniture based on the artificial reef production process developed by architect Wolf Hilbertz (Symbiotic Process Laboratory) and biologist Thomas J. Goreau to restore coral reefs and seabed (fauna, flora). This project is a reflection on an alterproduction from poor materials, primary technical devices, in relation to the economic and environmental context.
Mineral Accretion Factory consists of the immersion of a steel structure (the object’s skeleton) connected to a low-voltage supply (solar panel or windmill). A redox reaction starts, the object is self-generated, made of a material created from the ocean’s minerals. M.AF. demonstrates that a different ways are possible for production:* integrated within a natural setting (no factory) * using a basic apparatus and high scientific knowledge (low-tech + high-tech = wild-tech) * respecting biological production cycles (slow-tech)* effortlessly and costlessly
This research program through design gives rise to the possibility of setting up production processes that have a positive impact on the environment. It participates in the emergence of wildtech as defined by the French anthropologist Yann-Philippe Tastevin.
The project started in 2012 in Indonesia on Gili Trawangan island. Today, it continues on La Réunion island with the school of art in a research center on turtles.

description: The time evolution of structure factors in the disordering process of an initially phase separated lattice depends crucially on the microscopic mechanism which drives the disordering, such as Kawasaki dynamics or vacancy mediated disordering. Monte Carlo (MC) simulations show unexpected ``dips'' in the structure factors, which mean-field theory completely fails to capture. The disordering via vacancies is slower by a surprisingly large constant factor compared to Kawasaki dynamics. A phenomenological model is introduced in order to understand the dips, and an analytical solution of Kawasaki dynamics is derived, in excellent agreement with simulations. An outline is given on how to extend the analytical solution to the more complicated case of a wandering vacancy.

description: Alzheimer's Disease (AD) is one of the most concerned neurodegenerative diseases. In the last decade, studies on AD diagnosis attached great significance to artificial intelligence (AI)-based diagnostic algorithms. Among the diverse modality imaging data, T1-weighted MRI and 18F-FDGPET are widely researched for this task. In this paper, we propose a novel convolutional neural network (CNN) to fuse the multi-modality information including T1-MRI and FDG-PDT images around the hippocampal area for the diagnosis of AD. Different from the traditional machine learning algorithms, this method does not require manually extracted features, and utilizes the stateof-art 3D image-processing CNNs to learn features for the diagnosis and prognosis of AD. To validate the performance of the proposed network, we trained the classifier with paired T1-MRI and FDG-PET images using the ADNI datasets, including 731 Normal (NL) subjects, 647 AD subjects, 441 stable MCI (sMCI) subjects and 326 progressive MCI (pMCI) subjects. We obtained the maximal accuracies of 90.10% for NL/AD task, 87.46% for NL/pMCI task, and 76.90% for sMCI/pMCI task. The proposed framework yields comparative results against state-of-the-art approaches. Moreover, the experimental results have demonstrated that (1) segmentation is not a prerequisite by using CNN, (2) the hippocampal area provides enough information to give a reference to AD diagnosis.

Stochastic model of hysteresis

description: The methods of the probability theory have been used in order to build up a new model of hysteresis. It turns out that the reversal points of the control parameter (e. g., the magnetic field) are Markov points which determine the stochastic evolution of the process. It has been shown that the branches of the hysteresis loop are converging to fixed limit curves when the number of cyclic back-and-forth variations of the control parameter between two consecutive reversal points is large enough. This convergence to limit curves gives a clear explanation of the accommodation process. The accommodated minor loops show the return-point memory property but this property is obviously absent in the case of non-accommodated minor loops which are not congruent and generally not closed. In contrast to the traditional Preisach model the reversal point susceptibilities are non-zero finite values. The stochastic model can provide a good approximation of the Raylaigh quadratic law when the external parameter varies between two sufficiently small values.

description: In this paper, we analyse the entry of a cash crop producing foreign Contract Farming (CF) subsector within the agricultural sector of a country. Entry requires a cash crop price that is substantially above the price of the food crop already being produced within the country. Entry of CF could cause ‘vanishing’ of the food-crop sector. We employ a variant of 3×3 mixed Specific Factor-Heckscher Ohlin general equilibrium model of production and trade where introduction of a new policy may lead to the emergence of a new cash-crop sector resulting in finite changes where we show the possibilities of sectoral diversification with combinations of contract farming vis-à-vis traditional agriculture under some plausible conditions. Such ramifications could (a) increase GDP; (b) give rise to adverse distributional consequences for labour, and land-owner; (c) reduce domestic production of food and increase food import and hence, (d) aggravate food insecurity. Thus, CF might imply a tradeoff between food insecurity, inequality and growth. However, either zero CF and extremely high CF are suboptimal and hence, CF cannot be substitute of non-CF agricultural sector producing Food crops. In fact, fallacy of composition shows that aggregate has a price effect so that food-crop sector never disappears. Our results seem to be consistent when compared to some empirically robust conclusions found in the literature and some secondary data available in the FAO website.
Quantum Information Geometry in the Space of Measurements

Publisher: name: arXiv
Year: 2018
Subjects: subject: Quantum Physics (quant-ph)

description: We introduce a new approach to evaluating entangled quantum networks using information geometry. Quantum computing is powerful because of the enhanced correlations from quantum entanglement. For example, larger entangled networks can enhance quantum key distribution (QKD). Each network we examine is an n-photon quantum state with a degree of entanglement. We analyze such a state within the space of measured data from repeated experiments made by n observers over a set of identically-prepared quantum states -- a quantum state interrogation in the space of measurements. Each observer records a 1 if their detector triggers, otherwise they record a 0. This generates a string of 1's and 0's at each detector, and each observer can define a binary random variable from this sequence. We use a well-known information geometry-based measure of distance that applies to these binary strings of measurement outcomes, and we introduce a generalization of this length to area, volume and higher-dimensional volumes. These geometric equations are defined using the familiar Shannon expression for joint and mutual entropy. We apply our approach to three distinct tripartite quantum states: the GHZ state, the W state, and a separable state P. We generalize a well-known information geometry analysis of a bipartite state to a tripartite state. This approach provides a novel way to characterize quantum states, and it may have favorable scaling with increased number of photons.

description: We consider various one-dimensional non-equilibrium models, namely the {\it diffusion-limited pair-annihilation and creation model} (DPAC) and its unbiased version (the Lushnikov's model), the DPAC model with particle injection (DPACI), as well as (biased) diffusion-limited coagulation model (DC). We study the DPAC model using an approach based on a duality transformation and the generating function of the dual model. We are able to compute exactly the density and correlation functions in the general case with arbitrary initial states. Further, we assume that a source injects particles in the system. Solving, via the duality transformation, the equations of motions of the density and the non-instantaneous two-point correlation functions, we see how the source affects the dynamics. Finally we extend the previous results to the DC model with help of a {\it similarity transformation}.

description: This paper examines the collaborative practice between an analogue and a digital craft practitioner. It aims to illuminate ways in which digital tools can be used to translate handcrafted objects in collaborative craft practice and to address the following questions: 1) What forms of knowing and meaning making evolve in collaborative research through design practice? 2) What does it mean to explore material in Computer Aided Design (CAD) through Virtual Reality (VR)? Originating with a hand-knotted artifact, the study begins with the transformation of an analogue form into digital format using a range of techniques. These activities act as both a review of digital fabrication capabilities and an exploration of new thinking mechanisms offered by this emerging hybrid practice. The study broadens our understanding of the maker’s role within the capabilities and limitations of digital tools. Each iteration of digitally-fabricated objects was documented and reflected upon. This collaborative practice acts as a catalyst for established disciplines within art and design to collide and interact. Outcomes include mapping workflows within digital and analogue material practice, and reflection on how the materials and methods used in digital fabrication have the potential to expand the meanings connected to the things that are produced.

description: Since the x dependence of the axial-anomaly effect in inclusive polarized deep inelastic scattering is fixed, the transformation from the $\bar{MS}$ scheme to different factorization schemes are not arbitrary. If the quark spin distribution is demanded to be anomaly-free so that it does not evolve with $Q^2$ and hard gluons contribute to the first moment of $g_1(x)$, then all the moments of coefficient and splitting functions are fixed by perturbative QCD for a given $γ_5$ prescription, contrary to the commonly used Adler-Bardeen (AB) or AB-like scheme. It is urged that, in order to correctly demonstrate the effect of factorization scheme dependence, the QCD analysis of polarized structure functions in next-to-leading order should be performed, besides the $\bar{MS}$ scheme, in the chiral-invariant factorization scheme in which the axial anomaly resides in the gluon coefficient function, instead of the less consistent and ambiguous AB scheme.

description: The home environment is a complex design space, especially when it has multiple inhabitants. As such, the home presents challenges for the design of smart products. Householders may be different ages and have differing interests, needs, and attitudes towards technology. We pursued a research-through-design study with family households to envision and ‘co-create’ the future of data-enabled artifacts for their homes. We have iteratively developed domestic research artefacts for these households that are open, data-enabled, physical visualizations. These artefacts - called Domestic Widgets - are customisable in their design and functionality throughout their lifespan. The development process highlights design challenges for sustained co-creation and the leveraging of household creativity in (co-creation) research toolkits. These include the need to allow and inspire iterative customization, the need to accommodate changing roles within the home ecology, and the aim that such design should be inclusive for all family members (irrespective of age and technical proficiency), whilst maintaining a role and purpose in the home. We invite the RTD community to critically discuss our, and other, open and iterative end-user designs for sustained co-creation. By presenting unbuilt and interactive pre-built Domestic Widgets, we interactively foster engagement with practises of sustained co-creation.

description: We critically review the use of the exact renormalization group equations (ERGE) in the framework of the scalar theory. We lay emphasis on the existence of different versions of the ERGE and on an approximation method to solve it: the derivative expansion. The leading order of this expansion appears as an excellent textbook example to underline the nonperturbative features of the Wilson renormalization group theory. We limit ourselves to the consideration of the scalar field (this is why it is an introductory review) but the reader will find (at the end of the review) a set of references to existing studies on more complex systems.

description: We perform an extensive study of the influence of nuclear weak interactions on core-collapse supernovae (CCSNe), paying particular attention to consistency between nuclear abundances in the equation of state (EOS) and nuclear weak interactions. We compute properties of uniform matter based on the variational method. For inhomogeneous nuclear matter, we take a full ensemble of nuclei into account with various finite-density and thermal effects and directly use the nuclear abundances to compute nuclear weak interaction rates. To quantify the impact of a consistent treatment of nuclear abundances on CCSN dynamics, we carry out spherically symmetric CCSN simulations with full Boltzmann neutrino transport, systematically changing the treatment of weak interactions, EOSs, and progenitor models. We find that the inconsistent treatment of nuclear abundances between the EOS and weak interaction rates weakens the EOS dependence of both the dynamics and neutrino signals. We also test the validity of two artificial prescriptions for weak interactions of light nuclei and find that both prescriptions affect the dynamics. Furthermore, there are differences in neutrino luminosities by ~10% and in average neutrino energies by 0.25-1 MeV from those of the fiducial model. We also find that the neutronization burst neutrino signal depends on the progenitor more strongly than on the EOS, preventing a detection of this signal from constraining the EOS.

description: We derive a variational multiscale (VMS) finite element formulation for a viscoelastic, tensor-based blood damage model. The tensor equation is numerically stabilized by a logarithmic shape tensor description that prevents unphysical, negative eigenvalues. The resulting VMS stabilization terms for this so-called log-morph equation are presented together with their special numerical treatment. Results for a 2D rotating stirrer test case obtained from log-morph simulations with both SUPG and VMS stabilization show significantly improved numerical behavior if compared with Galerkin/least squares (GLS) stabilized untransformed morphology simulation results. The newly proposed method is also successfully applied to a state-of-the-art centrifugal ventricular assist device (VAD), and clear advantages of the VMS stabilization compared to the SUPG stabilized formulation are presented.

description: We have analysed K2 light curves for more than 3,000 low mass stars in the $\sim$8 Myr old Upper Sco association, the $\sim$125 Myr age Pleiades open cluster and the $\sim$700 Myr old Hyades and Praesepe open clusters to determine stellar rotation rates. Many of these K2 targets show two distinct periods, and for the lowest mass stars in these clusters virtually all of these systems with two periods are photometric binaries. The most likely explanation is that we are detecting the rotation periods for both components of these binaries. We explore the evolution of the rotation rate in both components of photometric binaries relative to one another and to non-photometric binary stars. In Upper Sco and the Pleiades, these low mass binary stars have periods that are much shorter on average and much closer to each other than would be true if drawn at random from the M dwarf single stars. In Upper Sco, this difference correlates strongly with the presence or absence of infrared excesses due to primordial circumstellar disks -- the single star population includes many stars with disks, and their rotation periods are distinctively longer on average than their binary star cousins of the same mass. By Praesepe age, the significance of the difference in rotation rate between the single and binary low mass dMs is much less, suggesting that angular momentum loss from winds for fully-convective zero-age main sequence stars erases memory of the rotation rate dichotomy for binary and single very low mass stars at later ages.

description: Using a quantum formulation of the master equation we study a kinetic Ising model with competing stochastic processes: the Glauber dynamics with probability $p$ and the Kawasaki dynamics with probability $1 - p$. Introducing explicitely the coupling to a heat bath and the mutual static interaction of the spins the model can be traced back exactly to a Ginzburg Landau functional when the interaction is of long range order. The dependence of the correlation length on the temperature and on the probability $p$ is calculated. In case that the spins are subject to flip processes the correlation length disappears for each finite temperature. In the exchange dominated case the system is strongly correlated for each temperature.

Materiais e métodos: Utilização de uma metodologia de revisão de literatura chamado TEMAC (Teoria do Enfoque Meta Analítico Consolidado) de Mariano & Rocha (2017), utilizando bases de dados como Web of Science e Google Scholar. A partir disso, foi feito um levantamento de dados para cálculos estatísticos em bases de dados como INCA (Instituto Nacional de Câncer José Alencar Gomes da Silva), IBGE (Instituto Brasileiro de Geografia e Estatística) e SISMAMA (Sistema de Informação do Câncer de Mama), no período de 2018 e utilizando outras duas metodologias de análise, fazendo uma comparação sobre seus resultados.  Resultados: Foi possível verificar a partir das duas metodologias que o Brasil possui mamógrafos mais que suficientes para atender a demanda populacional, porém o número de mamografias realizadas no ano de 2018 foi muito inferior aos 70% de cobertura estimados, atingindo apenas 25,9%. Além disso, a capacidade utilizada dos mamógrafos em todos os Estados foi inferior a 25% de sua capacidade máxima. Conclusão: Observa-se a necessidade de uma melhor distribuição dos equipamentos e de sua capacidade, além da inserção de políticas públicas para divulgação da importância do exame de mamografia, com o objetivo de aumentar a realização do mesmo.

description: Through experiments in design, this research explores the role of smartphones for mothers and young children.
Forming part of the material paraphernalia surrounding mother and child, smartphones are used as connection with work or social realms, as entertainment, pacification and educational resource, thus blurring boundaries between the private and the public and between work and play. As a result, smartphones offer competing discourses that this research explores.
Through the processes of drawing and making, a series of experimental designs were created to develop this research space. Evoking behaviours brought by the use of smartphones during childcare, these designs present mothers as complex users and explores the possibilities for design to reshape our relationship with technologies in family life. The development of these proposals formed a first exploratory stage in this research.
A second stage took place in the encounters between people and the designs. Through narratives that were suggestive and open to multiple interpretations, the proposals encouraged conversations about motherhood and the implicated role of smartphones. As research objects, they allowed for discoveries both for me as researcher and for those that encountered them.

description: In this paper we present Rep(AIR), a research-through-design olfactory interface for communicating moments of wear and tear on a bicycle. Rep(AIR) was designed as a probe in an autobiographical design inquiry to uncover qualities of the relationship between humans and objects as they relate to breakage and repair. Key used Rep(AIR), along with a personal probe notebook, on a 12 day international cycling trip to reflect on and document repairs and maintenance. We share findings from our analysis which extend the discourse on repair to include moments of wear, maintenance, and care as a part of the ongoing process of everyday use; recenter functionality to the human-object team, rather than the object alone; and highlight teamwork and collaboration as a way to challenge the hierarchical human-object narrative. We conclude by noting the role of Rep(AIR) as a tool which gave the bicycle a voice—revealing the often uncommunicated experience of wear and tear on an object.

description: Load flow analysis plays an important role in the planning, operation, optimization and control of a power system network. Over the years, the Calabar132Kv transmission system has witnessed voltage losses and load shedding due to insufficient power generation, inadequate or nonexistent reserves and the inability of the transmission companies to adequately manage the reactive power flow on the transmission line. This research titled “Load flow analysis of the 132kv Calabar transmission system for improved performance using Global-best Artificial Bee, Colony Algorithm (GABC)”. Electrical Transient Analyzer Program (ETAP) was used to evaluate the real timeload profile of the transmission network under consideration, and its optimization wassimulated in a MATLAB environment. The aim of the research is to evaluate the condition of the transmission network load flow performance for improved stability and overall efficiency. Thus, determining the quantity of voltage loss during transmission, thereby providing the network with a viable recommendation which will form a medium-term policy framework for operation that will enhance and deliver quality as well as efficient electricity supply to the people connected to the transmission line. The outcome of our evaluation reveals that, bus 30 has a generated voltage of 403megawatts and the load supply of 252megawatts and the losses alone accounted for 151megawatts. Thepower lost on the 132Kv Calabar network was largely due to over loading, long distance, transmission/distribution lines ageing as well as inadequate control infrastructure. Also, it is observed that the result of the reactive power optimization for 100 maximum trial runs of the 179-bus network is 74megawatts which shows a reduction in power loss after optimization. Havingevaluatedtheperformanceofthe132Kv Calabar sub-transmissionnetworkCross River State,asacasestudy,to increase power capacity, outdated 132KV sub-transmission networks should be modernized and continued investment is needed in the power sector, particularly with the expansion of 132Kv sub-transmission networks and the introduction of distributed generation. Finally, for future growth, very old power transformers should be replaced with ones that have a higher MVA capacity, particularly Amika feeder lines linking Ekpo-Abasi, Calabar-South, Mary-Slessor road, by the main entrance of the University of Calabar. This analysis provides a tangible and detailed information of the Calabar 132kv transmission system operation capacity as well as the data for timely improvement of the network by the power sector policy makers.

description: Flux of rigid or soft particles (such as drops, vesicles, red blood cells, etc.) in a channel is a complex function of particle concentration, which depends on the details of induced dissipation and suspension structure due to hydrodynamic interactions with walls or between neighboring particles. Through two-dimensional and three-dimensional simulations and a simple model that reveals the contribution of the main characteristics of the flowing suspension, we discuss the existence of an optimal volume fraction for cell transport and its dependence on the cell mechanical properties. The example of blood is explored in detail, by adopting the commonly used modeling of red blood cells dynamics. We highlight the complexity of optimization at the level of a network, due to the antagonist evolution of local volume fraction and optimal volume fraction with the channels diameter. In the case of the blood network, the most recent results on the size evolution of vessels along the circulatory network of healthy organs suggest that the red blood cell volume fraction (hematocrit) of healthy subjects is close to optimality, as far as transport only is concerned. However, the hematocrit value of patients suffering from diverse red blood cel pathologies may strongly deviate from optimality.

description: We have derived relations between full-width-half-maxima and equivalent widths of metallic absorption lines in the spectra of RR~Lyrae stars to estimate new upper limits on the axial equatorial rotational velocities of RR~Lyrae and metal-poor red horizontal branch stars (RHB). We also have derived the variations of RR~Lyrae macroturbulent velocities during the pulsation cycles. In RRab cycles the line widths are dominated by phase-dependent convolutions of axial rotation and macroturbulence, which we designate as V_macrot. The behavior of V_macrot is remarkably uniform among the RRab stars, but the behavior of V_macrot among RRc stars varies strongly from star to star. The RRab stars exhibit an upper limit on V_macrot of 5 +/- 1 km/s with weak evidence of an anti-correlation with T_eff. The RRc minima range from 2 to 12 km/s. The abrupt decline in large rotations with decreasing T_eff at the blue boundary of the instability strip and the apparently smooth continuous variation among the RRab and RHB stars suggests that HB stars gain/lose surface angular momentum on time scales short compared to HB lifetimes. V_macrot values for our metal-poor RHB stars agree well with those derived by Fourier analysis of an independent but less metal-poor sample of Carney et al. (2008); they conform qualitatively to the expectations of Tanner et al. (2013). A general conclusion of our investigation is that surface angular momentum as measured by V_rot*sini is not a reliable indicator of total stellar angular momentum anywhere along the HB.

description: We present new sets of nonperturbative fragmentation functions for D^*+- mesons, both at leading and next-to-leading order in the MS-bar factorization scheme with five massless quark flavors. They are determined by fitting the latest OPAL and ALEPH data on inclusive D^*+- production in e^+e^- annihilation. We take the charm-quark fragmentation function to be of the form proposed by Peterson et al. and thus obtain new values of the epsilon_c parameter, which are specific for our choice of factorization scheme. With these fragmentation functions, recent data on inclusive D^*+- photoproduction in ep collisions at HERA are reasonably well reproduced.

description: The extension of the Lieb-Schultz-Mattis theorem to dimensions larger than one is discussed. It is explained why the variational wave-function built by the previous authors is of no help to prove the theorem in dimension larger than one. The short range R.V.B. picture of Sutherland, Rokhsar and Kivelson, Read and Chakraborty gives a strong support to the assertion that the theorem is indeed valid in any dimension. Some illustrations of the general ideas are displayed on exact spectra.

Personal identity, transformative experiences, and the future self

description: The article explores the relation between personal identity and life-changing decisions such as the decision for a certain career or the decision to become a parent. According to L.A. Paul (Paul 2014), decisions of this kind involve “transformative experiences”, to the effect that - at the time we make a choice - we simply don’t know what it is like for us to experience the future situation. Importantly, she claims that some new experiences may be “personally transformative” by which she means that one may become a “new kind of person” having a different subjective perspective and “identity”. The article discusses this understanding of a transformed future self. It will be argued that different notions of identity can be distinguished with respect to Paul’s claim: the notion of identity in the sense of a (core) personality as well as the notion of numerical identity in the sense of sameness. By distinguishing these two notions it will become more clear how a future experience may indeed qualify as “personally transformative”. Moreover, it will be shown that the notion of a self-understanding of persons helps to further clarify the kind of change at issue.

description: Diskursgeschichtlich ist der digital turn nicht nur proklamiert, sondern auch in zahlreichen Publikationen niedergelegt und besetzt damit einen festen Platz in der Wissenschaftsgeschichtsschreibung des späten 20. und frühen 21. Jahrhunderts. Die Hinwendung zu digitalen Fragestellungen in den letzten Dezennien steht außer Frage. Längst ist klar, dass wir uns in einem Zeitalter bewegen, in dem digitale Technologien gesamtgesellschaftlich und damit auch für die geisteswissenschaftlichen Fächer an Bedeutung gewonnen haben, bestimmte Bereiche sogar dominieren und entsprechend in der Wissenschaftslandschaft auch staatliche Zuwendung und Förderung erfahren. Kaum eine Tagungsankündigung oder ein Sammelband, der sich den Digital Humanities widmet, kommt im Geleitwort ohne einen Appell aus, der die Relevanz des Digitalen unterstreicht und dadurch an ihrer diskursgeschichtlichen Verankerung mitarbeitet.
