description: We demonstrate a novel concept for operating graphene-based Hall sensors using an alternating current (AC) modulated gate voltage, which provides three important advantages compared to Hall sensors under static operation: 1) The sensor sensitivity can be doubled by utilizing both n- and p-type conductance. 2) A static magnetic field can be read out at frequencies in the kHz range, where the 1/f noise is lower compared to the static case. 3) The off-set voltage in the Hall signal can be reduced. This significantly increases the signal-to-noise ratio compared to Hall sensors without a gate electrode. A minimal detectable magnetic field Bmin down to 290 nT/sqrt(Hz) and sensitivity up to 0.55 V/VT was found for Hall sensors fabricated on flexible foil. This clearly outperforms state-of-the-art flexible Hall sensors and is comparable to the values obtained by the best rigid III/V semiconductor Hall sensors.

description: Evidential clustering is an approach to clustering in which cluster-membership uncertainty is represented by a collection of Dempster-Shafer mass functions forming an evidential partition. In this paper, we propose to construct these mass functions by bootstrapping finite mixture models. In the first step, we compute bootstrap percentile confidence intervals for all pairwise probabilities (the probabilities for any two objects to belong to the same class). We then construct an evidential partition such that the pairwise belief and plausibility degrees approximate the bounds of the confidence intervals. This evidential partition is calibrated, in the sense that the pairwise belief-plausibility intervals contain the true probabilities "most of the time", i.e., with a probability close to the defined confidence level. This frequentist property is verified by simulation, and the practical applicability of the method is demonstrated using several real datasets.

Geodesic distance: A descriptor of geometry and correlator of pre-geometric density of spacetime events

description: Classical geometry can be described either in terms of a metric tensor $g_{ab}(x)$ or in terms of the geodesic distance $σ^2(x,x')$. Recent work, however, has shown that the geodesic distance is better suited to describe the quantum structure of spacetime. This is because one can incorporate some of the key quantum effects by replacing $σ^2$ by another function $S[σ^2]$ such that $S[0]=L_0^2$ is non-zero. This allows one to introduce a zero-point-length in the spacetime. I show that the geodesic distance can be an emergent construct, arising in the form of a correlator $S[σ^2(x,y)]=\langle J(x)J(y)\rangle$, of a pregeometric variable $J(x)$, which, in turn, can be interpreted as the quantum density of spacetime events. This approach also shows why null surfaces play a special role in the interface of quantum theory and gravity. I describe several technical and conceptual aspects of this construction and discuss some of its implications.

description: The abolition of the milk quota regime in April 2015 will provide the opportunity for many profitable Irish dairy farms to increase their production levels. Market risk will influence the decision-making process at the farm level. Dairy farmers have acquired more recent experience of market risk through highly volatile market prices. This has the potential to affect risk attitudes and the selection of tools available to manage market risk. In this paper, we examine the market risk perceptions and management of Irish dairy farmers using 2011 Teagasc National Farm Survey data. We utilise experimental data in relation to forward contracting in order to examine the risk aversion and adoption rates for this particular risk management tool. Our findings suggest that recent price history and future price expectations have significant effects on decision-making in the area of forward contracting. Within the farm-gate diversification and the number of children in particular age categories have a positive and significant association with the adoption of forward contracting.

description: Family Caryophylliidae Dana, 1846   Diagnosis. Solitary and colonial. Colony formation by extracalicinal budding (rarely intracalicinal) budding, forming phaceloid or dendroid colonies. Costae commonly covered by stereome or epitheca. Septa exsert. Columella absent or formed by curled trabecular laths, solid, spongy. Pali or paliform lobes common. Endothecal dissepiments developed in some groups.
 Remarks. Gray (1847) is commonly referred to as the first author to have described the family Caryophylliidae (e.g. Milne Edwards 1857; Vaughan & Wells 1943; Alloiteau 1952a). However, as pointed out by Cairns (1989) one year prior to Gray’s work the family Caryophylliidae was created by Dana (1846: 364), which gives Dana priority of authorship.

description: The bulk photovoltaic effect is an example of a non-linear optical response that leads to a DC current that is relevant for photo-voltaic applications. In this work, we theoretically study this effect in the presence of electron-phonon interactions. Using the response function formalism we find that the non-linear optical response, in general, contains three operator correlation functions, one of which is not ordered in time. This latter correlator cannot be computed from equilibrium field theory. Using a semiclassical approach instead, we show that the bulk photovoltaic effect can be attributed to the dipole moment of the generated excitons. We then confirm the validity of the semiclassical result (which agrees with the non-interacting result) for non-linear DC response from a quantum master equation approach. From this formalism we find that, in contrast to usual linear response, the scattering rate has a strong implicit effect on the non-linear DC response. Most interestingly, the semiclassical treatment shows that the non-linear DC response for spatially inhomogeneous excitation profiles is strongly non-local and must involve the aforementioned out-of-time-ordered correlators that cannot be computed by equilibrium field theory.

description: We study the normal state and the superconducting transition in the Attractive Hubbard Model in three dimensions, using self-consistent diagrammatics. Our results for the self-consistent $T$-matrix approximation are consistent with 3D-XY power-law critical scaling and finite-size scaling. This is in contrast to the exponential 2D-XY scaling the method was able to capture in our previous 2D calculation. We find the 3D transition temperature at quarter-filling and $U=-4t$ to be $T_c=0.207t$. The 3D critical regime is much narrower than in 2D and the ratio of the mean-field transition to $T_c$ is about 5 times smaller than in 2D. We also find that, for the parameters we consider, the pseudogap regime in 3D (as in 2D) coincides with the critical scaling regime.

description: Blood flow in sickle cell disease (SCD) can substantially differ from normal blood flow due to significant alterations in the physical properties of the red blood cells (RBCs). Chronic complications, such as inflammation of the endothelial cells lining blood vessel walls, are associated with SCD, for reasons that are unclear. Here, detailed boundary integral simulations are performed to investigate an idealized model flow flow in SCD, a binary suspension of flexible biconcave discoidal fluid-filled capsules and stiff curved prolate capsules that represent healthy and sickle RBCs, respectively, subjected to pressure-driven flow in a planar slit. The key observation is that, unlike healthy RBCs that concentrate around the center of the channel and form an RBC-depleted layer (i.e. cell-free layer) next to the walls, sickle cells are largely drained from the bulk of the suspension and aggregate inside the cell-free layer, displaying strong margination. These cells are found to undergo a rigid-body-like rolling orbit near the walls. Furthermore, the additional shear stress on the walls induced by the presence of marginated cells is computed. Compared to the small fluctuations in wall shear stress for a suspension of healthy RBCs, large local peaks in wall shear stress are observed for the binary suspensions, due to the proximity of the marginated stiff cells to the walls. As endothelial cells are known to mechanotransduce physical forces such as aberrations in shear stress and convert them to physiological processes such as activation of inflammatory signals, these results may aid in understanding mechanisms for endothelial dysfunction associated with SCD.

description: We develop a hedonic price model on the Gironde estuary (south of France) in order to test the impact of vulnerability to flooding on land prices. The original contribution of our analysis relies on distinguishing the respective impact of two non-structural measures on land prices - the preventive strategy consisting in a flood hazard zoning and the curative response to flood events consisting in orders for natural disaster to initiate financial compensation. This analysis is conducted on three different segments of land market (agricultural, vineyards and residential segments). We pay a particular attention to the respective importance of attractiveness factors from vulnerability ones to explain land price. We use a two-step method to estimate the model, starting with a semi-parametric model (based on the distance to the estuary) followed by a feasible generalized spatial two-stage least squares (FGS2SLS) with which we correct the model from spatial autocorrelation and endogeneity. Our main results indicate that both zoning measure and institutional response to vulnerability to flooding have a significant impact on prices, but in an opposite direction. We discuss the policy implications related to flooding prevention in regards to land use changes.

description: Markov State Models (MSM) are widely used to elucidate dynamic properties of molecular systems from unbiased Molecular Dynamics (MD). However, the implementation of reweighting schemes for MSMs to analyze biased simulations, for example produced by enhanced sampling techniques, is still at an early stage of development. Several dynamical reweighing approaches have been proposed, which can be classified as approaches based on (i) Kramers rate theory, (ii) rescaling of the probability density flux, (iii) reweighting by formulating a likelihood function, (iv) path reweighting. We present the state-of-the-art and discuss the methodological differences of these methods, their limitations and recent applications.

description: In food retailing a high degree of static price dispersion between and within stores and between brands has been documented, but at the brand and/or retail outlet level the dynamic behaviour of prices, as well as its causes, have not been analysed in the European food market context. In this paper we estimate the dynamic pricing behaviour of brands at various retail outlets to identify the role of private (low-price brands) and national (high-price brands) labels to explain the dispersion of retail price dynamics. The results indicate significant asymmetries in cost pass-through processes, which vary between brands and outlets. In particular, private labels (low-price brands) adjust prices faster than national labels (high-price brands). Moreover, cost pass-through is slightly more (positive) asymmetrical for private labels than for high-price national brands.

description: In this paper we describe a framework for exploiting the semantics of Web services through UDDI registries. As a part of this framework, we extend the DAML-S upper ontology to describe the functionality we find essential for e-businesses. This functionality includes relating the services with electronic catalogs, describing the complementary services and finding services according to the properties of products or services. Once the semantics is defined, there is a need for a mechanism in the service registry to relate it with the service advertised. The ontology model developed is general enough to be used with any service registry. However when it comes to relating the semantics with services advertised, the capabilities provided by the registry effects how this is achieved. We demonstrate how to integrate the described service semantics to UDDI registries.

The mean-adjusted abnormal return model suggests that investors in 6 of the 18 commodity futures, examined in this study, either underreact or overreact to positive surprises. It also detects underreaction patterns in 8 commodity future prices following negative surprises. However, after conducting appropriate systematic risk and conditional heteroskedasticity adjustments, we show that almost all commodity futures react efficiently to shocks.

description: This paper measures inequality of opportunity in adult health in Colombia employing the 2010 Living Standards and Social Mobility Survey. I study the relationship between childhood circumstances and health status in adulthood drawing on Roemer (1998)'s analytical approach to inequality of opportunity. I use stochastic dominance tests to capture differences in the conditional distributions of self-assessed health. This test is an initial assessment of inequality emerging from early life circumstances like parental education, household socioeconomic status in childhood and parental survival. I also calculate a dissimilarity index to provide a measure of inequality of opportunity in health and obtain the relative contributions of various circumstances using logistic regressions and the Shapley value decomposition. Since a limited set of circumstances are observed in the data, my estimation of inequality of opportunity provides a lower bound on the true inequality of opportunity. The findings suggest that there is substantial inequality of opportunity in adult health. Moreover, differences in household socioeconomic status during childhood and parental educational attainment appear to be the most important dimensions of inequality of opportunity in adult health.

We analyze the main dynamical features of the model and relate in particular the Lyapunov spectrum with the transport properties in the stationary regime. We develop a thermodynamic formalism where we define formal Gibbs measure, partition function and pressure characterizing the avalanche distributions. We discuss the infinite size limit in this setting. We show in particular that a Lee-Yang phenomenon occurs in this model, for the only conservative case. This suggests new connexions to classical critical phenomena.

description: Extensive systematization of theoretical and experimental nuclear densities and of optical potential strengths exctracted from heavy-ion elastic scattering data analyses at low and intermediate energies are presented.The energy-dependence of the nuclear potential is accounted for within a model based on the nonlocal nature of the interaction.The systematics indicate that the heavy-ion nuclear potential can be described in a simple global way through a double-folding shape,which basically depends only on the density of nucleons of the partners in the collision.The poissibility of extracting information about the nucleon-nucleon interaction from the heavy-ion potential is investigated.

description: Interactive intelligent systems, i.e., interactive systems that employ AI technologies, are currently present in many parts of our social, public and political life. An issue reoccurring often in the development of these systems is the question regarding the level of appropriate human and computer contributions. Engineers and designers lack a way of systematically defining and delimiting possible options for designing such systems in terms of levels of automation. In this paper, we propose, apply and reflect on a method for human-computer configuration design. It supports the systematic investigation of the design space for developing an interactive intelligent system. We illustrate our method with a use case in the context of collaborative ideation. Here, we developed a tool for information extraction from idea content. A challenge was to find the right level of algorithmic support, whereby the quality of the information extraction should be as high as possible, but, at the same time, the human effort should be low. Such contradicting goals are often an issue in system development; thus, our method proposed helped us to conceptualize and explore the design space. Based on a critical reflection on our method application, we want to offer a complementary perspective to the value-centered design of interactive intelligent systems. Our overarching goal is to contribute to the design of so-called hybrid systems where humans and computers are partners.

description: A much improved determination of the transverse energy of jets has been carried out in ZEUS, using a correction procedure based on two independent methods. The first is based on a combination of tracking and calorimeter information which optimises the resolution of reconstructed kinematic variables. The conservation of energy and momentum in neutral current deep inelastic e^+p scattering events is exploited to determine the energy corrections by balancing the kinematic quantities of the scattered positron with those of the hadronic final state. The method has been independently applied to data and simulated events. The second method uses calorimeter cells as inputs to the jet algorithm. Simulated events are then used to provide a correction for the energy loss due to inactive material in front of the calorimeter. A detailed comparison of the jet transverse energy and the transverse energy of tracks in a cone around the jet provides the final correction. This procedure relies on an accurate simulation of charged tracks and so is less reliant on simulating the energy loss of neutral particles in inactive material. Final comparisons of the data and simulated events for both methods allow an uncertainty +/- 1% to be assigned to the jet energy scale.

description: Recent legal restrictions on water exports in the Southern Delta to protect listed fish populations have brought public attention to the trade-off relationship between fish conservation and agricultural economy. The restrictions may result in losses of agricultural returns in the Central Valley. This paper aims to examine the economic costs of conserving the endangered Winter-run Chinook salmon for two water year assumptions: one without environmental correlations and the other with the environmental correlations. The combination of a modified statewide agricultural production model and a multistage Winter-run Chinook salmon model allows me to assess the economic costs per age 3 and 4 adult for two cases. The estimated costs range from $1,304 to $114,966 for the first case and from $864 to $721,120 for the second case. They generally increase at an increasing rate as the pumping cuts back from 10% to 100%. The consideration of environmental correlations does not change the order of cost estimates: critical, dry, wet, above normal, and below normal. The results provide policy-makers with economic data on the tradeoffs in water management for the Southern Delta. One important factor in determining the agricultural losses is a climatic condition and the corresponding dependency of the farms on water exports.

description: We present a sub-kpc resolved study of the interstellar medium properties in SDP.81, a z=3.042 strongly gravitationally lensed dusty star-forming galaxy, based on high-resolution, multi-band ALMA observations of the FIR continuum, CO ladder and the [CII] line. Using a visibility-plane lens modelling code, we achieve a median source-plane resolution of ~200 pc. We use photon-dominated region (PDR) models to infer the physical conditions - far-UV field strength, density, and PDR surface temperature - of the star-forming gas on 200-pc scales, finding a FUV field strength of ~10^3-10^4 G0, gas density of ~10^5 cm^-3 and cloud surface temperatures up to 1500 K, similar to those in the Orion Trapezium region. The [CII] emission is significantly more extended than that FIR continuum: ~50 per cent of [CII] emission arises outside the FIR-bright region. The resolved [CII]/FIR ratio varies by almost 2 dex across the source, down to ~2x10^-4 in the star-forming clumps. The observed [CII]/FIR deficit trend is consistent with thermal saturation of the C+ fine-structure level occupancy at high gas temperatures. We make the source-plane reconstructions of all emission lines and continuum data publicly available.

description: Price endogeneity has been ignored in previous analyses of food demand in China. We examine agricultural input price data from the China National Bureau of Statistics and use reduced-form price equations to account for price endogeneity in this setting. Applying our unique econometric approach to the analysis of provincial-level food demand in China, we find strong statistical evidence of price endogeneity. Models that ignore price endogeneity result in substantially biased elasticities and misleading estimates of future food demand in China.

description: X-ray assisted nuclear excitation by electron capture (NEEC) into inner-shell atomic holes in a plasma environment generated by strong optical lasers is investigated theoretically. The considered scenario involves the interaction of a strong optical laser with a solid-state nuclear target leading to the generation of a plasma. In addition, intense x-ray radiation from an X-ray Free Electron Laser (XFEL) produces inner-shell holes in the plasma ions, into which NEEC may occur. As case study we consider the $4.85$-keV transition starting from the 2.4 MeV long-lived $^{\mathrm{93m}}$Mo isomer that can be used to release the energy stored in this metastable nuclear state. We find that the recombination into $2p_{1/2}$ inner-shell holes is most efficient in driving the nuclear transition. Already at few hundred eV plasma temperature, the generation of inner-shell holes can allow optimal conditions for NEEC, otherwise reached for steady-state plasma conditions in thermodynamical equilibrium only at few keV. The combination of x-ray and optical lasers presents two advantages: first, NEEC rates can be maximized at plasma temperatures where the photoexcitation rate remains low. Second, with mJ-class optical lasers and an XFEL repetition rate of $10$ kHz, the NEEC excitation number can reach $\sim 1$ depleted isomer per second and is competitive with scenarios recently envisaged at petawatt-class lasers.

description: The electronic structure of the unconventional superconductor UTe$_2$ was studied by resonant photoelectron spectroscopy (RPES) and angle-resolved photoelectron spectroscopy (ARPES) with soft X-ray synchrotron radiation. The partial $\mathrm{U}~5f$ density of states of UTe$_2$ were imaged by the $\mathrm{U}~4d$--$5f$ RPES and it was found that the $\mathrm{U}~5f$ state has an itinerant character, but there exists an incoherent peak due to the strong electron correlation effects. Furthermore, an anomalous admixture of the $\mathrm{U}~5f$ states into the $\mathrm{Te}~5p$ bands was observed at a higher binding energy, which cannot be explained by band structure calculations. On the other hand, the band structure of UTe$_2$ was obtained by ARPES and its overall band structure were mostly explained by band structure calculations. These results suggest that the $\mathrm{U}~5f$ states of UTe$_2$ have itinerant but strongly-correlated nature with enhanced hybridization with the $\mathrm{Te}~5p$ states.

title: Talking about sugar in South Africa: A grounded policy reflection in the context of NCDs and HIV
Creators: name: Graff, H
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 2021

description: Introduction: On 1 April 2018 the South African Sugary Beverages Levy (RSA levy) came into effect, with the goal of lowering the consumption of sugar-sweetened beverages (SSBs) across the population. The aim of this study was to explore grassroots understandings and perceptions of food choices, food access, and national policy within the context of a country with a double burden of non-communicable diseases (NCDs) and HIV, using individual and community experience as a metric for critical reflection. Methods: Focus group discussions were used to examine RSA’s levy as an example of people’s experience of a national policy aimed at improving health. I explored the lived context, food environments, and knowledge of and impact from the RSA levy among young adults (18-35)in an urban township outside of Cape Town (Ulutsha Town). Using a critical theory approach, I focused on two elements of the taxation policy mechanism: price influence over purchasing and consumption, and public awareness of the impact of sugary beverages on health. This policy reflection used a semi-iterative process of thematic development based on descriptive coding of the focus group discussion transcripts to identify key themes. Results: The primary themes from the focus group discussions were used to critically reflect on the RSA levy day-to-day. These themes are unemployment, anxiety, the cost of food and sugary drinks, and the role of the government in shaping and giving health. This reflection of the RSA levy sits in contrast to many of the other assessments and evaluations conducted prior to and following the RSA levy implementation. Wider, socio-economic barriers and structures within Ulutsha Town are currently preventing the RSA levy from having its intended impact within this community. Conclusions: As a policy designed to shape health, the RSA levy sits on top of entrenched structural barriers already in place for the young people of Ulutsha Town. Furthermore, young people in Ulutsha Town are navigating the shifting intersect between “old” HIV and “new” NCDs within their community. A combination of analytic approaches is necessary to evaluating policy and developing better and healthier public policies in the future.
