Correlated Disordered Plasmonic Nanostructures Arrays for Augmented Reality

Plasmonic resonators are excellent candidates to control reflectance of functionalized substrates. Because of their subwavelength characteristic dimensions, they can even be used to modify the color of transparent glass plates without altering the transparency quality. Their spatial arrangement must be carefully chosen so that the plates do not produce nonspecular diffraction, whatever their spatial density. We compare here the response of silver nanoparticles (NPs) arrays with different NPs sizes, spatial densities, and arrangements (periodic and correlated disordered). The effects of these geometrical parameters are analyzed in detail by measuring the reflectance and transmittance spectra in visible wavelength. We show that correlated disordered gratings attenuate diffraction effects appearing at lower spatial densities while keeping similar reflectance and transmittance responses and maintaining clear transparency of the glass plate.

The origin and genetic differentiation of the socially parasitic aphid Tamalia inquilinus

Social and brood parasitisms are nonconsumptive forms of parasitism involving the exploitation of the colonies or nests of a host. Such parasites are often related to their hosts and may evolve in various ecological contexts, causing evolutionary constraints and opportunities for both parasites and their hosts. In extreme cases, patterns of diversification between social parasites and their hosts can be coupled, such that diversity of one is correlated with or even shapes the diversity of the other. Aphids in the genus Tamalia induce galls on North American manzanita (Arctostaphylos) and related shrubs (Arbutoideae) and are parasitized by nongalling social parasites or inquilines in the same genus. We used RNA sequencing to identify and generate new gene sequences for Tamalia and performed maximum‐likelihood, Bayesian and phylogeographic analyses to reconstruct the origins and patterns of diversity and host‐associated differentiation in the genus. Our results indicate that the Tamalia inquilines are monophyletic and closely related to their gall‐forming hosts on Arctostaphylos, supporting a previously proposed scenario for origins of these parasitic aphids. Unexpectedly, population structure and host‐plant‐associated differentiation were greater in the non‐gall‐inducing parasites than in their gall‐inducing hosts. RNA‐seq indicated contrasting patterns of gene expression between host aphids and parasites, and perhaps functional differences in host‐plant relationships. Our results suggest a mode of speciation in which host plants drive within‐guild diversification in insect hosts and their parasites. Shared host plants may be sufficient to promote the ecological diversification of a network of phytophagous insects and their parasites, as exemplified by Tamalia aphids.

Combining magneto-hydrostatic constraints with Stokes profiles inversions

Context.Inversion techniques applied to the radiative transfer equation for polarized light are capable of inferring the physical parameters in the solar atmosphere (temperatureT, magnetic fieldB, and line-of-sight velocityvlos) from observations of the Stokes vector (i.e., spectropolarimetric observations) in spectral lines. Inferences are usually performed in the (x, y, τc) domain, whereτcrefers to the optical-depth scale. Generally, their determination in the (x, y, z) volume is not possible due to the lack of a reliable estimation of the gas pressure, particularly in regions of the solar surface harboring strong magnetic fields.Aims. We aim to develop a new inversion code capable of reliably inferring the physical parameters in the (x, y, z) domain.Methods. We combine, in a self-consistent way, an inverse solver for the radiative transfer equation (Firtez-DZ) with a solver for the magneto-hydrostatic equilibrium, which derives realistic values of the gas pressure by taking the magnetic pressure and tension into account.Results. We test the correct behavior of the newly developed code with spectropolarimetric observations of two sunspots recorded with the spectropolarimeter (SP) instrument on board the Hinode spacecraft, and we show how the physical parameters are inferred in the (x, y, z) domain, with the Wilson depression of the sunspots arising as a natural consequence of the force balance. In particular, our approach significantly improves upon previous determinations that were based on semiempirical models.Conclusions. Our results open the door for the possibility of calculating reliable electric currents in three dimensions,j(x, y, z), in the solar photosphere. Further consistency checks would include a comparison with other methods that have recently been proposed and which achieve similar goals.
Conformal anti-invariant submersions from cosymplectic manifolds

We introduce conformal anti-invariant submersions from cosymplectic manifolds onto Riemannian manifolds. We give an example of a conformal anti-invariant submersion such that characteristic vector field $\xi$ is vertical. We investigate the geometry of foliations which are arisen from the defi nition of a conformal submersion and show that the total manifold has certain product structures. Moreover, we examine necessary and su fficient conditions for a conformal anti-invariant submersion to be totally geodesic and check the harmonicity of such submersions.

Panic buying research: A systematic literature review and future research agenda

Panic buying has re-emerged as a ‘new’ normal consumer behaviour and has become a coping mechanism for real and perceived dangers associated with COVID-19 Despite the need for a better understanding of the panic buying phenomenon, there has been a lack of scholarly research on this topic This study seeks to fill this gap In this article, we systematically review extant studies in panic buying from the last two decades We analyse and categorize them according to Callahan's 4W (2014) review structure and Paul and Rosado-Serrano's (2019) TCCM framework We found that the existing publications in panic buying are fragmented across multiple disciplines Due to the nature of the panic-induced behaviour, most of them have been written as a reaction to the pandemic crisis We contribute to marketing research by providing theoretical, contextual and methodological insights into the field of panic buying Furthermore, we develop a research agenda related to retailer and consumer perspectives Additionally, we identify research issues related to policymaking and governance, as well as broader societal impacts that need to be addressed in the future © 2021 The Authors International Journal of Consumer Studies published by John Wiley & Sons Ltd
Linear Predictability in MRI Reconstruction: Leveraging Shift-Invariant Fourier Structure for Faster and Better Imaging

Over the past several decades, many different types of computational imaging approaches have been proposed for improving MRI. In this paper, we provide an overview of methods that assume that MRI Fourier data is linearly predictable. Linear prediction is well known in signal processing and may be most recognizable for its usefulness in speech processing and spectrum estimation applications. In MRI, linear predictability implies that data can be sampled below the conventional Nyquist rate, since unmeasured data may be imputed as a shift-invariant linear combination of measured samples. Linear predictive methods include some of the earliest methods in the computational MRI reconstruction field, some of the most widely utilized computational MRI methods in modern clinical practice, and some of the most flexible and versatile modern computational imaging approaches that are enabling unprecedented new styles of data acquisition. In addition, the concept of linear predictability can be used to unify a number of more classical MRI reconstruction constraints, but without needing to make the strong assumptions of classical constrained reconstruction methods.
EmpDG: Multi-resolution Interactive Empathetic Dialogue Generation

A humanized dialogue system is expected to generate empathetic replies, which should be sensitive to the users’ expressed emotion. The task of empathetic dialogue generation is proposed to address this problem. The essential challenges lie in accurately capturing the nuances of human emotion and considering the potential of user feedback, which are overlooked by the majority of existing work. In response to this problem, we propose a multi-resolution adversarial model – EmpDG, to generate more empathetic responses. EmpDG exploits both the coarse-grained dialogue-level and fine-grained token-level emotions, the latter of which helps to better capture the nuances of user emotion. In addition, we introduce an interactive adversarial learning framework which exploits the user feedback, to identify whether the generated responses evoke emotion perceptivity in dialogues. Experimental results show that the proposed approach significantly outperforms the state-of-the-art baselines in both content quality and emotion perceptivity.

Prediction of critical safety factor of slopes using multiple regression and neural network

The estimation of slope stability is an engineering problem that involves many parameters. The impact of these 6 parameters on the stability of slopes can be understood by the use of computational tools like regression analysis, neural 7 networks, etc. These computational tools are highly sophisticated modelling techniques which are capable of modelling very 8 complex functions. They act as a powerful tool for modelling, especially when the relationships between the underlying data 9 is unknown. It can identify and understand the correlated patterns present between the input data sets and corresponding target 10 values. In this paper, the input data for the three dimensional slope stability estimation includes the geotechnical and geometrical 11 input parameters and the 3-D critical safety factor (Fcs) as the output data. On successful completion of the model, the performance 12 of the same is measured and the results are compared to those obtained by means of standard analytical methods. The results 13 showed that the predicted values are very close to the analytical values and provide good correlation between the input variables. 14
Error bounds with almost radical dependence on the number of components for multi-category classification, vector quantization and switching regression

This paper presents a simple approach for obtaining efficient error bounds in learning problems involving multiple components. In particular, we obtain error bounds with a close to radical dependency on the number of components for multi-category classification, vector quantification and switching regression when the regularization scheme relies on a sum of norms over the components. These results are obtained thanks to the combination of a number of structural results on Rademacher complexities and a suitable handling of the structure of the regularizer.
Influence of Spin‐Orbit Interaction on the Transport Processes in Ferromagnetic Nickel Alloys, in the Presence of a Degeneracy of the 3d Band

Assuming that two of the five branchs of the 3d band intersect, it is shown that singularities result in the transport properties when such an intersection happens to occur at the Fermi level. The ``ferromagnetic anisotropy of resistivity'' Δρ/ρ0 (often called magnetoresistance effect) is expected to have a strong maximum; using Born approximation for impurity scattering, and simple models of the 3d and 4s bands, a detailed computation provides an order of magnitude of 20% for the value of Δρ/ρ0 at the maximum. On the other hand, assuming the validity of current theories of the ``extraordinary Hall conductivity'' γHs due to Smit or to Karplus and Luttinger, γHs may be expected to change sign. This is precisely the behavior of Δρ/ρ0 and γHs observed by Smit in Co‐Ni and Fe‐Ni alloys, for an electron concentration equal to 27.7 electrons/atom.
Population Ageing: Alternative measures of dependency and implications for the future of work

The world’s population is getting older, a phenomenon that has important implications for the future of work. Persons aged 55 years and over are expected to outnumber all children aged 0 to 14 years by 2035 and the entire child and youth population aged 0 to 24 years by 2080. As a direct consequence of population ageing, the number of older workers aged 55 to 64 years is increasing and is set to equal one quarter of the global labour force by 2030. This paper examines the projected labour force participation trends of older workers to 2030 and discusses the future of economic dependency for developing, emerging and developed countries. It introduces five alternative measures of economic dependency to account for the fact that persons of working age may not be working or may be facing employment conditions that compromise their capacity to support themselves and others. Such conditions include scenarios where workers are unable to work as many hours as they would like, or where they are in situations of vulnerable employment or working poverty. These alternative measures therefore not only take into account demographic and quantitative labour market characteristics, such as age structure, activity status and unemployment, but also consider qualitative dimensions such as underemployment, labour income and vulnerability. Using a very rich ILO data set that provides a consistent series of labour market data for all countries with forecasts to 2024 and beyond, the paper provides estimates for these new dependency measures and makes a number of policy recommendations to address the impact of ageing on decent work. ​
Scientific Opinion on the annual Post-Market Environmental Monitoring (PMEM) report from Monsanto Europe S.A. on the cultivation of genetically modified maize MON 810 in 2011

Following the request from the European Commission, the Panel on Genetically Modified Organisms of the European Food Safety Authority (EFSA GMO Panel) assessed the monitoring report for the 2011 growing season of maize MON 810 provided by Monsanto Europe S.A. The EFSA GMO Panel already assessed the 2009 and 2010 monitoring reports and followed the same approach as for the assessment of the methodology applied by the applicant for monitoring maize MON 810 in 2011. The EFSA GMO Panel considered the plan for insectresistant management and addressed the comments raised by the applicant on its previous recommendations for improving the methodology of the resistance monitoring of target pests. The EFSA GMO Panel also paid particular attention to the design and analysis of the farmer questionnaires. The EFSA GMO Panel notes similar shortcomings in the overall methodology for the post-market environmental monitoring of maize MON 810 as in the previous monitoring reports. Hence, while the EFSA GMO Panel reiterates its previous recommendations for the improvement of the methodology, it also clarifies and elaborates on those related to the monitoring of resistance evolution in target pests. However, from the data submitted by the applicant, the EFSA GMO Panel does not identify adverse effects on the environment, human and animal health due to maize MON 810 cultivation during the 2011 growing season. The outcomes of the 2011 monitoring report do not invalidate the previous EFSA GMO Panel‟s scientific opinions on maize MON 810. © European Food Safety Authority, 2013
Analysis of DG approximations for Stokes problem based on velocity‐pseudostress formulation

In this article, we first discuss the well posedness of a modified LDG scheme of Stokes problem, considering a velocity‐pseudostress formulation. The difficulty here relies on the fact that the application of classical Babuška‐Brezzi theory is not easy, so we proceed in a nonstandard way. For uniqueness, we apply a discrete version of Fredholm's alternative theorem, while the a priori error analysis is done introducing suitable projections of exact solution. As a result, we prove that the method is convergent, and under suitable regularity assumptions on the exact solution, the optimal rate of convergence is guaranteed. Next, we explore two stabilizations to the previous scheme, by adding least squares type terms. For these cases, well posedness and the a priori error estimates are proved by the application of standard theory. We end this work with some numerical experiments considering our third scheme, whose results are in agreement with the theoretical properties we deduce. © 2017 Wiley Periodicals, Inc.

Acute Effects of Fine Particulate Air Pollution on Cardiac Arrhythmia: The APACR Study

Background: The mechanisms underlying the relationship between particulate matter (PM) air pollution and cardiac disease are not fully understood. Objectives: We examined the effects and time course of exposure to fine PM [aerodynamic diameter ≤ 2.5 μm (PM2.5)] on cardiac arrhythmia in 105 middle-age community-dwelling healthy nonsmokers in central Pennsylvania. Methods: The 24-hr beat-to-beat electrocardiography data were obtained using a high-resolution Holter system. After visually identifying and removing artifacts, we summarized the total number of premature ventricular contractions (PVCs) and premature atrial contractions (PACs) for each 30-min segment. A personal PM2.5 nephelometer was used to measure individual-level real-time PM2.5 exposures for 24 hr. We averaged these data to obtain 30-min average time–specific PM2.5 exposures. Distributed lag models under the framework of negative binomial regression and generalized estimating equations were used to estimate the rate ratio between 10-μg/m3 increases in average PM2.5 over 30-min intervals and ectopy counts. Results: The mean ± SD age of participants was 56 ± 8 years, with 40% male and 73% non-Hispanic white. The 30-min mean ± SD for PM2.5 exposure was 13 ± 22 μg/m3, and PAC and PVC counts were 0.92 ± 4.94 and 1.22 ± 7.18. Increases of 10 μg/m3 in average PM2.5 concentrations during the same 30 min or the previous 30 min were associated with 8% and 3% increases in average PVC counts, respectively. PM2.5 was not significantly associated with PAC count. Conclusion: PM2.5 exposure within approximately 60 min was associated with increased PVC counts in healthy individuals.
A protoplanet candidate in the transition disk around the Herbig Ae star MWC 758

Transition disks offer the extraordinary opportunity to look for newly born planets and investigate the early stages of planet formation. In this context we observed the Herbig A5 star MWC 758 with the L band vector vortex coronagraph installed in the near-infrared camera and spectrograph NIRC2 at the Keck II telescope, with the aim of unveiling the nature of the spiral structure by constraining the presence of planetary companions in the system. Our high-contrast imaging observations show a bright (delta L=7.0+/-0.3 mag) point-like emission, south of MWC 758 at a deprojected separation of about 20 au (r=0.111+/- 0. 004 arcsec) from the central star. We also recover the two spiral arms (south-east and north-west), already imaged by previous studies in polarized light, and discover a third one to the south-west of the star. No additional companions were detected in the system down to 5 Jupiter masses beyond 0.6 arcsec from the star. We propose that the bright L band emission could be caused by the presence of an embedded and accreting protoplanet, although the possibility of it being an asymmetric disk feature cannot be excluded. The spiral structure is probably not related to the protoplanet candidate, unless on an inclined and eccentric orbit, and it could be due to one (or more) yet undetected planetary companions at the edge of or outside the spiral pattern. Future observations and additional simulations will be needed to shed light on the true nature of the point-like source and its link with the spiral arms.
Immediate hypersensitivity reaction to gadolinium-based MR contrast media.

PURPOSE To determine the incidence and risk factors of immediate hypersensitivity reactions to gadolinium-based magnetic resonance (MR) contrast agents. MATERIALS AND METHODS Institutional review board approval and a waiver of informed consent were obtained. A retrospective study of patients who had been given gadolinium-based MR contrast media between August 2004 and July 2010 was performed by reviewing their electronic medical records. In addition to data on immediate hypersensitivity reaction, the kinds of MR contrast media and demographic data including age, sex, and comorbidity were collected. To compare the groups, the χ(2) test, Fisher exact test, χ(2) test for trend, Student t test, analysis of variance test, and multiple logistic regression test were performed. RESULTS A total of 112 immediate hypersensitivity reactions (0.079% of 141 623 total doses) were identified in 102 patients (0.121% of 84 367 total patients). Among the six evaluated MR contrast media, gadodiamide had the lowest rate (0.013%) of immediate hypersensitivity reactions, while gadobenate dimeglumine had the highest rate (0.22%). The rate for immediate hypersensitivity reactions was significantly higher in female patients (odds ratio = 1.687; 95% confidence interval: 1.143, 2.491) and in patients with allergies and asthma (odds ratio = 2.829; 95% confidence interval: 1.427, 5.610). Patients with a previous history of immediate hypersensitivity reactions had a higher rate of recurrence after reexposure to MR contrast media (30%) compared with the incidence rate in total patients (P < .0001). The incidence of immediate hypersensitivity reactions increased depending on the number of times patients were exposed to MR contrast media (P for trend = .036). The most common symptom was urticaria (91.1%), and anaphylaxis occurred in 11 cases (9.8%). The mortality rate was 0.0007% because of one fatality. CONCLUSION The incidence of immediate hypersensitivity reactions to MR contrast media was 0.079%, and the recurrence rate of hypersensitivity reactions was 30% in patients with previous reactions.
