Hyperspectral Image Denoising Based on Global and Nonlocal Low-Rank Factorizations

The ever-increasing spectral resolution of hyperspectral images (HSIs) is often obtained at the cost of a decrease in the signal-to-noise ratio of the measurements, thus calling for effective denoising techniques. HSIs from the real world lie in low-dimensional subspaces and are self-similar. The low dimensionality stems from the high correlation existing among the reflectance vectors, and self-similarity is common in real-world images. In this article, we exploit the above two properties. The low dimensionality is a global property that enables the denoising to be formulated just with respect to the subspace representation coefficients, thus greatly improving the denoising performance and reducing the computational complexity during processing. The self-similarity is exploited via a low-rank tensor factorization of nonlocal similar 3-D patches. The proposed factorization hinges on the optimal shrinkage/thresholding of the singular value decomposition (SVD) singular values of low-rank tensor unfoldings. As a result, the proposed method is user friendly and insensitive to its parameters. Its effectiveness is illustrated in a comparison with state-of-the-art competitors.

Climate Variability and Transnational Migration: A Dyadic Analysis

This research builds upon and extends earlier research by studying whether people leave their homes and migrate to other states due to weather changes associated with climate variability. In particular, I examine how push and pull factors jointly influence emigration. Empirically, the theoretical arguments are analysed quantitatively with time-series cross-section data on transnational migration since the 1960s. The results suggest that climate indicators are strongly and robustly associated with transnational migration. The dyadic nature of the analysis allows for a close examination of patterns across pairs of countries by clearly distinguishing between “source” and “destination. ” Controlling for unobserved influences via country and year fixed effects, as well as a series of robustness checks, further increases the confidence in this finding. This research substantially improves our understanding of climate-induced migration and emphasizes that it is, in fact, a global phenomenon.
CohLitheSP: A new technique to study quality in Specialized Translation

The aim of this work is to analyse the benefits of introducing a code in Python language to analyze quality in terms of the appropriateness of the texts as regards reading.

DIFFUSE COPLANAR SURFACE BARRIER DISCHARGE IN NITROGEN: MICRODISCHARGES STATISTICAL BEHAVIOR

We studied statistical behavior of microdischarges of diffuse coplanar surface barrier discharge (DCSBD) operated in nitrogen atmosphere at two input voltage regimes. We measured spectrally unresolved discharge patterns together with discharge electrical parameters using high-speed iCCD camera and digital storage oscilloscope. External synchronization enabled us to measure the discharge pattern during positive and/or negative half-period of input high voltage in the single-shot mode of operation. The comparison of microdischarges behavior during positive, negative and both half periods of input high voltage was performed for two levels of input voltage, i.e. voltage slightly above ignition voltage and high above ignition voltage (“overvoltage”). The number of microchannels crossing discharge gap was counted and compared with number of microdischarge current peaks observed during corresponding half-period of input high voltage. The relations of those incidences was shown and discussed.
Isotopic fractionation induced by a surface effect influences the estimation of the hydrological process of topsoil

Isotopic heterogeneity in soil water has hindered the application of isotope compositions (δ18O and δ2H) in soil water dynamics. This heterogeneity has been suggested to be caused by soil properties such as organic matter (OM) and clay content. However, this is yet to be verified in field soil. We sampled the organic layer (O‐horizon soil) with highly decomposed organic material and the A‐horizon soil in western Sichuan, China, and equilibrated these samples with vapour created by unconfined labelling water. The relationship between soil properties and isotopic fractionation (εT/U) between unconfined water and the total soil water was used to determine the line‐conditioned excess (lc‐excess) and source rain of A‐horizon field soil by removing the influence of confined water. Equilibration experiments demonstrated a significant isotopic difference between the εT/U levels in the A‐horizon and O‐horizon soils, indicating that OM plays an important role in isotopic fractionation. In field samples, the lc‐excess of the unconfined A‐horizon water was, on an average, 2.5‰ higher than that of bulk soil water. The average offsets between the annual rain and the estimated source rain of soil water decreased by 5.0 and 0.5‰ for hydrogen and oxygen after removing the influence of confined water. Isotopic heterogeneity should not be ignored while examining the evaporation of soil water, soil source rain, and hence the recent ‘two water worlds’ hypothesis, which is especially true for cases in which the soils contain high levels of OM.
On multiple solutions for a fourth order nonlinear singular boundary value problems arising in epitaxial growth theory

In this article, we consider the fourth order non‐self‐adjoint singular boundary value problem 1rr1rrϕ′′′′=ϕ′ϕ″r+λ, with λ as a parameter measures the speed at which new particles are deposited. This differential equation is non‐self‐adjoint, so finding its solutions is not easy by usual methods. Also, this does not have a unique solution; therefore, finite differences and discrete methods may not be applicable. Here, to find approximate solutions, we propose to use the Adomian decomposition method (ADM) and compute the approximate solutions which are fully dependent on the size of the parameter λ. Here, we prove theoretically that the approximate solutions converge to the exact solutions. For small positive values of parameter λ, the above equation has two solutions. No solutions could be found for large positive values of the parameter. The uniqueness of the solution may not be guaranteed for a fixed positive value of the parameter. For negative values of parameter existences of the solution are always guaranteed.

Are fiscal deficits inflationary in Nigeria? New evidence from bounds testing to cointegration with structural breaks

In this paper, we model the relationship between fiscal deficit and inflation for Nigeria using annual data from 1980 to 2016. We employ the linear ARDL approach and account for structural breaks using the Bai and Perron (2003) test that allows for multiple structural changes in regression models. The paper finds that the fiscal deficit is a major determinant of inflation along with other macroeconomic factors considered in the study. However, we observe that it may be necessary to pretest for structural breaks when modelling the relationship between the fiscal deficit and the price level, as it performs better than when structural events are not considered. The results imply that a fiscal management process that does not encourage increased revenue and reduce fiscal deficits will further worsen the level of inflation in the country.
Improvement of Antifouling and Antibacterial Properties of Poly(ether sulfone) UF Membrane by Blending with a Multifunctional Comb Copolymer

Herein we report a novel PES UF membrane via blending with a multifunctional comb copolymer containing capsaicin analogue and hydrophilic groups. The copolymer P(H–P–A) was synthesized by a facile free radical polymerization method using poly(ethylene glycol) methyl ether methacrylate (PEGMA), 2-hydroxyethyl acrylate (HEA), and N-(4-hydroxy-3-methoxy benzyl) acrylamide (HMBA) as monomers. The resultant copolymer was then incorporated into PES to prepare PES blend membranes by the classic NIPS method. Specifically, the effects of the P(H–P–A) amount and different copolymer composition in the casting solutions on the structure and properties of the modified membranes were investigated in detail. The surface hydrophilicity and antifouling property of the membranes were remarkably improved, which was demonstrated by surface wettability measurement and BSA filtration experiments. Moreover, the modified membranes showed excellent antibacterial capability against Escherichia coli because of the capsaicin-analogu.
Understanding the modifiable areal unit problem in dockless bike sharing usage and exploring the interactive effects of built environment factors

ABSTRACT Understanding the influence mechanisms of dockless bike-sharing usage is essential for land use planning and bike scheduling strategy implementation. Although various studies have been carried out to explore the impact of built environment (BE) factors on bike-sharing usage, few studies have examined the modifiable areal unit problem (MAUP). Moreover, previous studies mainly focused on the separate effect of each factor but neglected the interactions between these factors. Taking Shenzhen, China as the case, this study fills these two gaps by employing the geographical detector method to examine the MAUP in dockless bike-sharing usage as well as the interactive effects of BE factors. The results revealed that the influences of most BE variables are sensitive to the spatial areal units, which have informed urban planners what built-environment factors should be paid more attention to at certain spatial scales. Additionally, through the comparisons between single effect and interactive effect, this study revealed some interesting findings that can provide scientific basis for temporal rebalance strategy for the innovative and high-density metropolis in China.
Financial development and economic growth nexus in SSA economies: The moderating role of telecommunication development

Abstract The economic growth of most sub-Saharan African countries in the past years has not been able to equalize with other regions. Even though financial development has been highlighted in several empirical literature as a factor that could spur up economic growth, the level of financial development in sub-Saharan Africa is not effectively channeled into desired levels of economic growth. However, there is an indication in the literature that financial development will be more relevant to the economic growth of sub-Saharan African economies that have strong telecommunication infrastructure. Using the system General Method of Moment estimation technique, the paper found that telecommunication infrastructure enhances the effect of financial development on the economic growth of sub-Saharan African economies. It is therefore recommended that sub-Saharan African economies should apply appropriate measures to boost their telecommunication infrastructure so that gains from the financial sector can effectively be channeled into economic growth.
Mechanical and Barrier Properties of Hydroxy Propyl Methyl Cellulose Edible Polymer Films with Plasticizer Combinations

Edible films and coatings have received considerable attention in recent years because of their advantages including use as edible packaging materials over synthetic films. This could contribute to the reduction of environmental pollution. Edible films of hydroxy propyl methyl cellulose (HPMC) containing mixtures of glycerol(Gly) and polyethylene glycol (PEG) as plasticizers were prepared by water solution caste technique and evaluated mechanical (tensile strength, elongation at break. burst strength, impact strength and Young's modulus) and barrier properties (water vapor transmission rate and oxygen transmission rate), color and haze properties were measured. Intermolecular interactions between HPMC-glycerol and HPMC-PEG were measured using FT-IR technique. Thermal properties were investigated by differential scanning calorimetry analysis. All these properties were found to be improved with variation of plasticizers concentrations. Practical Applications This work is on food packaging. Polymer films are edible films. These films are eco-friendly and bio-plastics and have good mechanical, barrier and optical properties.

Persuading communicating voters

This paper studies a multiple-receiver Bayesian persuasion model, where a sender communicates with receivers who have homogeneous beliefs and aligned preferences. The sender wants to implement a proposal and commits to a communication strategy which sends private (possibly) correlated messages to the receivers, who are in an exogenous and commonly known network. Receivers can observe their neighbors’ private messages and after updating their beliefs, vote sincerely on the proposal. We examine how networks of shared information affect the sender’s gain from persuasion and find that in many cases it is not restricted by the additional information provided by the receivers’ neighborhoods. Perhaps surprisingly, the sender’s gain from persuasion is not monotonically decreasing with the density of the network.
Growing up with a brother or sister with Down syndrome: Adult siblings’ perceptions of their childhood relationships

ABSTRACT Background The increased life expectancy of people with Down syndrome puts pressure on parents, who are usually the main caregivers but who find caring more difficult as they get older. The quality of the support provided by brothers and sisters depends on the intra-family relationships they build when growing up. Methods 121 adult siblings of people with Down syndrome completed a questionnaire on their perceptions of their childhood relationships. Results Brothers’ and sisters’ relationships with a sibling with Down syndrome were mostly (very) positive, but this was not always the case for their relationships with their parents and other siblings. Factors affecting these relationships include respondent’s sex, number of siblings, and sibling position. Conclusions In addition to simple risk and protective factors, we identified parameters that should be taken into account when providing support to siblings and parents of people with Down syndrome.
Efeito de doses crescentes de lodo de esgoto sobre fração da matéria orgânica e CTC de um latossolo cultivado com cana-de-açúgar

A Typic Haplorthox in Guariba county, Sao Paulo State, Brazil, was limed and amended with mineral fertilizers or sewage sledge (4, 8, 16, or 32 t/ha) and cropped with sugar cane. Treatments with sewage sledge received potassium, as potassium chloride, to equalize the content of this element in all the fertilized treatments. Soil samples were collected soon before fertilization and at 77, 105, 140 168, 196, 230, and 473 days after planting the sugarcane. The samples were air dried and analysed for cation exchange capacity (CEC), total organic carbon, fulvic acid, humic acid and humin. Sewage sludge at 32 t/ha significantly increased total organic carbon and CEC. Sewage sludge organic carbon was quickly transformed into soil humin carbon, which was the predominant fraction in soil organic matter Humin was the fraction of the organic matter that more closely correlated with the soil CEC (r=0.59 *** ). The soil total organic carbon/soil humin carbon ratio decreased from planting to 230 days, faster in the first 140 days, an increased after sugar-cane harvesting. The soil humin carbon/soil humic matter carbon ratio showed a trend similar to that of the sugarcane plant biomass production; the soil organic fulvic acid/soil organic humic carbon ratio decreased in the first stage of the experiment and then tended to increase
