description: Cet atlas présente les résultats de l'exploitation d’images hyperspectrales et de données Lidar à des fins de cartographie des plateformes récifales de la Réunion. Les méthodes mises en œuvres (traitement du signal, classification, démélangeage spectral, ...) ont permis de générer différents produits cartographiques à haute résolution parmi lesquels des images en réflectance et des fonds marins (jusqu'à des profondeurs supérieures à 30 m), un MNT bathymétrique haute résolution (40 cm) de la plate-forme récifale, des cartes de synthèse permettant d'appréhender qualitativement et quantitativement les taux de couverture en algues, sable, corail et herbier. En intégrant l'ensemble de ces informations, un indicateur surfacique, proxi de la "vitalité corallienne" mesurée sur le terrain, est proposé comme préfiguration d'un potentiel indicateur DCE d'état de santé de la masse d'eau récifale. L'ensemble de ces cartes contribue enfin à mieux caractériser et appréhender l'hétérogénéité spatiale si caractéristique de ces zones récifales dans une perspective d'optimisation des réseaux pérennes de suivi de la DCE qui doivent être mis en œuvre à partir de 2015.

description: Many real-world interactions (e.g., researcher collaborations and email communication) occur among multiple entities. These group interactions are naturally modeled as hypergraphs. In graphs, transitivity is helpful to understand the connections between node pairs sharing a neighbor, and it has extensive applications in various domains. Hypergraphs, an extension of graphs, are designed to represent group relations. However, to the best of our knowledge, there has been no examination regarding the transitivity of real-world group interactions. In this work, we investigate the transitivity of group interactions in real-world hypergraphs. We first suggest intuitive axioms as necessary characteristics of hypergraph transitivity measures. Then, we propose a principled hypergraph transitivity measure HyperTrans, which satisfies all the proposed axioms, with a fast computation algorithm Fast-HyperTrans. After that, we analyze the transitivity patterns in real-world hypergraphs distinguished from those in random hypergraphs. Lastly, we propose a scalable hypergraph generator THera. It reproduces the observed transitivity patterns by leveraging community structures, which are pervasive in real-world hypergraphs. Our code and datasets are available at https://github.com/kswoo97/hypertrans.

description: We put forward a novel method for producing ultrarelativistic high-density high-polarization positrons through a single-shot interaction of a strong laser with a tilted solid foil. In our method, the driving laser ionizes the target, and the emitted electrons are accelerated and subsequently generate abundant $γ$ photons via the nonlinear Compton scattering, dominated by the laser. These $γ$ photons then generate polarized positrons via the nonlinear Breit-Wheeler process, dominated by a strong self-generated quasi-static magnetic field $\mathbf{B}^{\rm S}$. We find that placing the foil at an appropriate angle can result in a directional orientation of $\mathbf{B}^{\rm S}$, thereby polarizing positrons. Manipulating the laser polarization direction can control the angle between the $γ$ photon polarization and $\mathbf{B}^{\rm S}$, significantly enhancing the positron polarization degree. Our spin-resolved quantum electrodynamics particle-in-cell simulations demonstrate that employing a laser with a peak intensity of about $10^{23}$ W/cm$^2$ can obtain dense ($\gtrsim$ 10$^{18}$ cm$^{-3}$) polarized positrons with an average polarization degree of about 70\% and a yield of above 0.1 nC per shot. Moreover, our method is feasible using currently available or upcoming laser facilities and robust with respect to the laser and target parameters. Such high-density high-polarization positrons hold great significance in laboratory astrophysics, high-energy physics and new physics beyond the Standard Model.

description: La campagne SEDICAR (SEDIment CARottage) à bord du navire océanographique Marion Dufresne s’est déroulée dans le golfe de Gascogne. Le navire et ses équipements scientifiques associés étaient mis à disposition par l’IPEV. Au cours des trois parties, le navire a relié Brest à Brest (24-28 juin 03), Brest à Bordeaux (12-14 juillet 03) et Bordeaux à Las Palmas (14 au 24 juillet 03). Pour la première partie, l’équipe scientifique SEDICAR a bénéficié du soutien de l’équipe partielle de la mission précédente PICASSO ; pour la troisième partie, elle est venue renforcer l’équipe de la mission PICABIA. Les travaux de la campagne SEDICAR se sont terminés le 19 juillet 2003 à la sortie du golfe de Gascogne. Les responsables scientifiques étaient Jean-François Bourillet (parties 1 & 2), Jean-Louis Turon et Jean-François Bourillet (partie 3). La mise à disposition de 10 jours de campagnes sur les 16 estimés nécessaires pour mener à bien les objectifs de la demande de campagne nous ont obligés à réduire de 2/3 le nombre initial de sites (de 26 à 17). Le choix s’est porté sur les sites pour lesquels le carottier géant Calypso représentait le meilleur voire l’unique moyen de prélèvement. C’est ainsi que la plupart des sites du plateau continental, sableux et dans une moindre mesure peu profonds, ont été écartés en faveur des sites argilo-silteux de la pente et du glacis. La première partie de la mission a été écourtée (5 sites réalisés sur 11) en raison d’une avarie importante sur le treuil. En raison de mises au point diverses nécessaires après l’arrêt technique, aucune des 2 carottes prévues n’a été prélevée pendant la seconde partie. Quatre carottes sur 4 ont été réalisées au cours de la troisième partie mais en intégrant les 2 de la deuxième partie au détriment de 2 carottes.

description: We discuss the following question: For a function f of two or more variables which is convex in the directions of coordinate axes, how can its trace g(x) = f(x, x, ..., x) look like? In the two-dimensional case, we provide some necessary and sufficient conditions, as well as some examples illustrating that our approach does not seem to be appropriate for finding a characterization in full generality. For a concave function g, however, a characterization in the two-dimensional case is established.

description: Recently, nonlinear displaced number states (NDNSs) have been \emph{manually} introduced, in which the deformation function $f(n)$ has been artificially added to the well-known displaced number states (DNSs). In this paper, after expressing enough physical motivation of our procedure, four distinct classes of NDNSs are presented by applying algebraic and group treatments. To achieve this purpose, by considering the DNSs and recalling the nonlinear coherent states formalism, the NDNSs are logically defined through an algebraic consideration. In addition, by using a particular class of Gilmore-Perelomov-type of $SU(1,1)$ and a class of $SU(2)$ coherent states, the NDNSs are introduced via group theoretical approach. Then, in order to examine the nonclassical behaviour of these states, sub-Poissonian statistics by evaluating Mandel parameter and Wigner quasi-probability distribution function associated with the obtained NDNSs are discussed, in detail.

Microscopic analysis of proximity-induced superconductivity and metallization effects in superconductor-germanium hole nanowires

description: Low-dimensional germanium hole devices are promising systems with many potential applications such as hole spin qubits, Andreev spin qubits, and Josephson junctions, and can serve as a basis for the realization of topological superconductivity. This vast array of potential uses for Ge largely stems from the exceptionally strong and controllable spin-orbit interaction (SOI), ultralong mean free paths, long coherence times, and compatibility with complementary metal-oxide-semiconductor (CMOS) technology. However, when brought into proximity with a superconductor (SC), metallization normally diminishes many useful properties of a semiconductor, for instance, typically reducing the g factor and SOI energy, as well as renormalizing the effective mass. In this paper, we consider metallization of a Ge nanowire (NW) in proximity to a SC, explicitly taking into account the three-dimensional (3D) geometry of the NW. We find that proximitized Ge exhibits a unique phenomenology of metallization effects, where the 3D cross section plays a crucial role. For instance, in contrast to expectations, we find that SOI can be enhanced by strong coupling to the superconductor. We also show that the thickness of the NW plays a critical role in determining both the size of the proximity-induced pairing potential and metallization effects, since the coupling between the NW and SC strongly depends on the distance of the NW wave function from the interface with the SC. In the absence of electrostatic effects, we find that a sizable gap opens only in thin NWs ($d \lesssim 3$ nm). In thicker NWs, the wave function must be pushed closer to the SC by electrostatic effects in order to achieve a sizable proximity gap such that the required electrostatic field strength can simultaneously induce a strong SOI.

description: This report (Deliverable 4.3) provides a comprehensive overview of innovative methods that have been identified to assess multi-hazard risk dynamics. These methods consider the spatial and temporal dynamics in exposure and vulnerability resulting from interactions between multiple hazards and disaster risk reduction measures. The subsequent research supports risk managers in understanding risk dynamics and the effects of DRR measures, enabling decision makers to be better prepared for and recover from multi-hazard risk events.
 The report discusses existing databases and vulnerability statistics, as well as novel methods and data sources, highlighting opportunities and challenges in using these methods and data sources. Notable methods include developing a comprehensive vulnerability database for urban areas, utilising novel data streams like Google Trends and newspaper articles for understanding impact durations, using night-time light satellite data for recovery pattern analysis, implementing Machine Learning for multi-risk assessment, and employing Disaster Forensic Analysis to learn from past events and the impact of risk reduction measures.

description: Estimating sizes of hidden or hard-to-reach populations is an important problem in public health. For example, estimates of the sizes of populations at highest risk for HIV and AIDS are needed for designing, evaluating and allocating funding for treatment and prevention programmes. A promising approach to size estimation, relatively new to public health, is the network scale-up method (NSUM), involving two steps: estimating the personal network size of the members of a random sample of a total population and, with this information, estimating the number of members of a hidden subpopulation of the total population. We describe the method, including two approaches to estimating personal network sizes (summation and known population). We discuss the strengths and weaknesses of each approach and provide examples of international applications of the NSUM in public health. We conclude with recommendations for future research and evaluation.

Conditions for Photospherically Driven Alfvenic Oscillations to Heat the Solar Chromosphere by Pedersen Current Dissipation

Publisher: name: arXiv
Year: 2014
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: A magnetohydrodynamic model that includes a complete electrical conductivity tensor is used to estimate conditions for photospherically driven, linear, non-plane Alfvenic oscillations extending from the photosphere to the lower corona to drive a chromospheric heating rate due to Pedersen current dissipation that is comparable to the net chromospheric net radiative loss of $\sim 10^7$ ergs-cm$^{-2}$-sec$^{-1}$. The heating rates due to electron current dissipation in the photosphere and corona are also computed. The wave amplitudes are computed self-consistently as functions of an inhomogeneous background (BG) atmosphere. The effects of the conductivity tensor are resolved numerically using a resolution of 3.33 m. The oscillations drive a chromospheric heating flux $F_{Ch} \sim 10^7 - 10^8$ ergs-cm$^{-2}$-sec$^{-1}$ at frequencies $ν\sim 10^2 - 10^3$ mHz for BG magnetic field strengths $B \gtrsim 700$ G and magnetic field perturbation amplitudes $\sim 0.01 - 0.1$ $B$. The total resistive heating flux increases with $ν$. Most heating occurs in the photosphere. Thermalization of Poynting flux in the photosphere due to electron current dissipation regulates the Poynting flux into the chromosphere, limiting $F_{Ch}$. $F_{Ch}$ initially increases with $ν$, reaches a maximum, and then decreases with increasing $ν$ due to increasing electron current dissipation in the photosphere. The resolution needed to resolve the oscillations increases from $\sim 10$ m in the photosphere to $\sim 10$ km in the upper chromosphere, and is proportional to $ν^{-1/2}$. Estimates suggest that these oscillations are normal modes of photospheric flux tubes with diameters $\sim 10-20$ km, excited by magnetic reconnection in current sheets with thicknesses $\sim 0.1$ km.

description: We present a computational scheme for orbital-free density functional theory (OFDFT) that simultaneously provides access to all-electron values and preserves the OFDFT linear scaling as a function of the system size. Using the projector augmented-wave method (PAW) in combination with real-space methods we overcome some obstacles faced by other available implementation schemes. Specifically, the advantages of using the PAW method are two fold. First, PAW reproduces all-electron values offering freedom in adjusting the convergence parameters and the atomic setups allow tuning the numerical accuracy per element. Second, PAW can provide a solution to some of the convergence problems exhibited in other OFDFT implementations based on Kohn-Sham codes. Using PAW and real-space methods, our orbital-free results agree with the reference all-electron values with a mean absolute error of 10~meV and the number of iterations required by the self-consistent cycle is comparable to the KS method. The comparison of all-electron and pseudopotential bulk modulus and lattice constant reveal an enormous difference, demonstrating that in order to assess the performance of OFDFT functionals it is necessary to use implementations that obtain all-electron values. The proposed combination of methods is the most promising route currently available. We finally show that a parametrized kinetic energy functional can give lattice constants and bulk moduli comparable in accuracy to those obtained by the KS PBE method, exemplified with the case of diamond.

description: Each summer, the IFREMER laboratory of Arcachon monitors, in the scope of an agreement with the Regional Conchological Comity of Arcachon, the reproduction of Pacific oysters in the Arcachon Bay. This monitoring aims to provide oyster farmers with information necessary to the spat collecting: - dates and amount of spawn, - larval development speed, - presence of the most evolved stages in the habitat (close to fixation). Reproduction is monitored from June to September, with plankton being sampled four times a week on different representative sites. Oyster larvae at different stages are counted. At the end of the reproduction period (September-October), larval recruitment on collectors is estimated via the counting of the spats collected, at various collection areas. Furthermore, the results gathered in the framework of the IFREMER “RESCO” network are used to characterise the spawners' maturation in the spring preceding the reproduction period. This report presents the results of the 2014 reproduction season, and their interpretation through old data.
description: Durant chaque saison estivale, le laboratoire IFREMER d'Arcachon réalise, dans le cadre d'une convention avec Comité Régional Conchylicole (CRC) Arcachon-Aquitaine, le suivi de la reproduction des huîtres creuses dans le Bassin d'Arcachon. Ce suivi a pour but de fournir aux ostréiculteurs les informations nécessaires à la mise en oeuvre du captage de naissains : - dates et importance des pontes, - vitesse de développement des larves, - présence dans le milieu des stades les plus évolués (proches de la fixation). Le suivi de la reproduction est réalisé entre juin et septembre, des pêches de plancton étant réalisées quatre fois par semaine dans différents sites représentatifs du Bassin. Les larves d'huîtres aux différents stades y sont dénombrées. A l'issue de la saison de reproduction (octobre-novembre), l'estimation du recrutement larvaire sur les collecteurs est effectuée par comptage des naissains captés sur un certain nombre de collecteurs (tuiles et coupelles) prélevés dans les différents secteurs de captage. Par ailleurs, les résultats obtenus dans le cadre du réseau « RESCO » de l'IFREMER sont utilisés pour caractériser la maturation des géniteurs au cours du printemps précédant la saison de reproduction. Ce rapport présente les résultats de la saison de reproduction 2014, interprétés à la lumière des séries de données anciennes.

description: We apply the quantum optimal control theory based on the Krotov method to implement single-qubit $X$ and $Z$ gates and two-qubit CNOT gates for inductively coupled superconducting flux qubits with fixed qubit transition frequencies and fixed off-diagonal qubit-qubit coupling. Our scheme that shares the same advantage of other directly coupling schemes requires no additional coupler subcircuit and control lines. The control lines needed are only for the manipulation of individual qubits (e.g., a time-dependent magnetic flux or field applied on each qubit). The qubits are operated at the optimal coherence points and the gate operation times (single-qubit gates $< 1$ ns; CNOT gates $\sim 2$ ns) are much shorter than the corresponding qubit decoherence time. A CNOT gate or other general quantum gates can be implemented in a single run of pulse sequence rather than being decomposed into several single-qubit and some entangled two-qubit operations in series by composite pulse sequences. Quantum gates constructed via our scheme are all with very high fidelity (very low error) as our optimal control scheme takes into account the fixed qubit detuning and fixed two-qubit interaction as well as all other time-dependent magnetic-field-induced single-qubit interactions and two-qubit couplings. The effect of leakage to higher energy-level states and the effect of qubit decoherence on the quantum gate operations are also discussed.

description: Syphilis has made a dramatic resurgence in China during the past two decades. During the Cultural Revolution (1966–76), sexually transmitted infections (STI) were so uncommon that they were removed from standard Chinese medical training curricula.1 As China's market economy expanded during 1980s economic reforms, reported STI, including syphilis infection, quickly re-appeared. An evolving STI reporting infrastructure largely assembled in the 1990s has noted increasing syphilis cases, particularly during the past 5 years (figure 1).2 3 Now syphilis is among the top five reported communicable diseases in many major province-level municipalities and provinces.4 While China's syphilis case reporting system and potential determinants of spread have been outlined in other reviews,2 there have been many studies on syphilis infection among female sex workers (FSW),5 6 this review analyses syphilis in China from the perspective of two critical high-risk populations: men who have sex with men (MSM) and low-tier FSW. Here we define low-tier FSW as women who usually solicit clients on the street or public outdoor places and sell sex for less than approximately €2–10 per client. Although preventing adverse outcomes associated with syphilis in pregnancy is important,7 this review focuses …

description: Aerosols play a critical role in atmospheric chemistry, and affect clouds, climate, and human health. However, the spatial coverage of satellite-derived aerosol optical depth (AOD) products is limited by cloud cover, orbit patterns, polar night, snow, and bright surfaces, which negatively impacts the coverage and accuracy of particulate matter modeling and health studies relying on air pollution characterization. We present a random forest model trained to capture spatial dependence of AOD and produce higher coverage through imputation. By combining the models with and without the mean filters, we are able to create full-coverage high-resolution daily AOD in the conterminous U.S., which can be used for aerosol estimation and other studies leveraging air pollutant concentration levels.

description: In galaxy clusters, the relations between observables in X-ray and millimeter wave bands and the total mass have normalizations, slopes and redshift evolutions that are simple to estimate in a self-similar scenario. We study these scaling relations and show that they can be efficiently expressed, in a more coherent picture, by fixing the normalizations and slopes to the self-similar predictions, and advocating, as responsible of the observed deviations, only three physical mass-dependent quantities: the gas clumpiness $C$, the gas mass fraction $f_g$ and the logarithmic slope of the thermal pressure profile $β_P$. We use samples of the observed gas masses, temperature, luminosities, and Compton parameters in local clusters to constrain normalization and mass dependence of these 3 physical quantities, and measure: $C^{0.5} f_g = 0.110 (\pm 0.002 \pm 0.002) \left( E_z M / 5 \times 10^{14} M_{\odot} \right)^{0.198 (\pm 0.025 \pm 0.04)}$ and $β_P = -d \ln P/d \ln r = 3.14 (\pm 0.04 \pm 0.02) \left( E_z M / 5 \times 10^{14} M_{\odot} \right)^{0.071 (\pm 0.012 \pm 0.004)}$, where both a statistical and systematic error (the latter mainly due to the cross-calibration uncertainties affecting the \cxo\ and \xmm\ results used in the present analysis) are quoted. The degeneracy between $C$ and $f_g$ is broken by using the estimates of the Compton parameters. Together with the self-similar predictions, these estimates on $C$, $f_g$ and $β_P$ define an inter-correlated internally-consistent set of scaling relations that reproduces the mass estimates with the lowest residuals.

description: ObjectivesTo compare two methods for sampling female sex workers (FSWs) for bio-behavioural surveillance. We compared the populations of sex workers recruited by the venue-based Priorities for Local AIDS Control Efforts (PLACE) method and a concurrently implemented network-based sampling method, respondent-driven sampling (RDS), in Liuzhou, China.MethodsFor the PLACE protocol, all female workers at a stratified random sample of venues identified as places where people meet new sexual partners were interviewed and tested for syphilis. Female workers who reported sex work in the past 4 weeks were categorised as FSWs. RDS used peer recruitment and chain referral to obtain a sample of FSWs. Data were collected between October 2009 and January 2010. We compared the socio-demographic characteristics and the percentage with a positive syphilis test of FSWs recruited by PLACE and RDS.ResultsThe prevalence of a positive syphilis test was 24% among FSWs recruited by PLACE and 8.5% among those recruited by RDS and tested (prevalence ratio 3.3; 95% CI 1.5 to 7.2). Socio-demographic characteristics (age, residence and monthly income) also varied by sampling method. PLACE recruited fewer FSWs than RDS (161 vs 583), was more labour-intensive and had difficulty gaining access to some venues. RDS was more likely to recruit from areas near the RDS office and from large low prevalence entertainment venues.ConclusionsSurveillance protocols using different sampling methods can obtain different estimates of prevalence and population characteristics. Venue-based and network-based methods each have strengths and limitations reflecting differences in design and assumptions. We recommend that more research be conducted on measuring bias in bio-behavioural surveillance.

description: Non-covalent interactions are a key ingredient to determine the structure, stability, and dynamics of materials, molecules, and biological complexes. However, accurately capturing these interactions is a complex quantum many-body problem, with no efficient solution available on classical computers. A widely used model to accurately and efficiently model non-covalent interactions is the Coulomb-coupled quantum Drude oscillator (cQDO) many-body Hamiltonian, for which no exact solution is known. We show that the cQDO model lends itself naturally to simulation on a photonic quantum computer, and we calculate the binding energy curve of diatomic systems by leveraging Xanadu's Strawberry Fields photonics library. Our study substantially extends the applicability of quantum computing to atomistic modeling, by showing a proof-of-concept application to non-covalent interactions, beyond the standard electronic-structure problem of small molecules. Remarkably, we find that two coupled bosonic QDOs exhibit a stable bond. In addition, our study suggests efficient functional forms for cQDO wavefunctions that can be optimized on classical computers, and capture the bonded-to-noncovalent transition for increasing interatomic distances.

Détermination des stades d'intermue chez Macrabrachium rosenbergii (caridae) et Penaeus merguiensis (peneidae)

description: Ce travail représente une contribution à l'étude de la biologie et de la croissance de la crevette d'eau douce Macrobrachium rosenbergi i (de Man)
et de la crevette de mer Penaeus mergaiensis (de Han).
Les étapes successives de la période d'intermue ont été déterminées sur des juvéniles afin de pouvoir par la suite approfondir les connaissances de
quelques paramètres physiologiques relatifs à la croissance de ces deux espèces.
Les notions fondamentales sur le cycle d'intermue des crustacés apportées par Drach (1939) pour les Brachyoures adultes, sont valables avec de légères modifications pour tous les Décapodes qui présentent un exosquelette bien calcifié. Le schéma a été légèrement modifié par le m~e auteur (1944-1967) pour les Natantia dont l'exosquelette est peu calcifié.
D'autres études portent sur ces m~es Décapodes (Riatt 1948 ; Travis 1955, 1957 ; Tchernigovtzeff 1965 ; Stevenson 1968) ainsi que sur les Amphipodes (Charniaux-Legrand 1952) et les Isopodes (Tchernigovtzeff et Ragage Willigens 1968) ••• pour n'en citer que quelques uns.
La méthode de détermination des stades d'intermue et son application générale aux crustacés ont été discutées par Drach et Tchernigovtzeff (1967).
Comme il n'existe aucune étude de détail sur les Penaeidae, il a paru intéressant d'eXaminer les stades d'intermue de P. merguiensis et de les comparer à ceux de M. rosenbergii, Caridae voisine de Palaemon serratus (Pennant) étudiée par Drach (1944).

description: An updated version of The Infinite Adjacency & 1D Single Wavefunction Paradigm . With Expanded formalism and concepts extended into more rigorous form and order. In RSM, spacetime is modeled as a single, coherent superfluid lattice—a continuum in which one spatial dimension collapses, yielding “infinite adjacency” and instantaneous (zero-lag) phase locking. In this framework, quantum gravity resonance is enhanced as the vacuum approaches absolute zero, leading to the emergence of low-entropy (negentropic) pockets that underlie both cosmic phenomena (e.g., orbital resonances, dark matter–like anomalies, black hole vortex formation) and rapid neural synchrony. By applying a fractal recursion operator and defining bridging operators for phase amplification, RSM reinterprets dark matter “lumps,” variable light-speed measurements, and nonlocal neural coherence as artifacts of our discrete, vantage-limited sampling of a universal, frictionless wavefunction. Furthermore, the introduction of a Duality Principle explains how complementary ¨double states¨ (e.g., fluid vs. crystal, abstract vs. manifest, past & present) merge through intentional coupling, establishing consciousness as an active mediator and creative architect in the unfolding of reality. This paper presents the mathematical formalism, physical analogies, and philosophical implications of RSM, proposing that our observed anomalies arise from a limited (3D, stroboscopically sampled) vantage on an eternally unified, frictionless quantum field. The quest to reconcile quantum mechanics with gravity and to uncover the origins of macroscopic order has led to many bold hypotheses. The Resonance Synchronization Model (RSM) challenges our conventional picture by positing that spacetime may behave as a superfluid under near-0 K conditions. In RSM, one spatial dimension can collapse, leading to “infinite adjacency,” where every point along this axis is identical and phase variations vanish. Simultaneously, quantum gravitational excitations, whose resonance strength increases as the effective temperature drops, give rise to coherent “negentropic pockets” and exotic phenomena from planetary orbits to rapid neural phase synchronization.

description: This article examines the metaphors that are used to represent dementia in British tabloid newspapers over a ten-year period (2010–2019). The analysis takes a corpus-based approach to metaphor identification and analysis, utilizing in particular the corpus linguistic technique of collocation analysis. Metaphors are considered in terms of the ‘targets’ they frame, which include the following aspects of dementia: (i.) prevalence; (ii.) causes; (iii.) symptoms and prognosis; (iv.) lived experience; and (v.) responses. A range of metaphors are identified, with the tabloids exhibiting a particular preference for metaphors which construct dementia as an agentive and violent entity and people with dementia as passive victims, and which foreground preventative responses to dementia such as pharmacological intervention and individual behavior change. It is argued that such metaphors have the potential to contribute to dementia stigma and place focus on preventing or eliminating dementia while backgrounding responses which may help people to “live well” with the syndrome in the here-and-now. Metaphors which frame dementia as a companion or which the experience of dementia as a journey are put forward as potentially less stigmatizing alternatives which might better reflect the particularities of this complex public health issue.
