description: The current status of the physics of massive neutrinos is reviewed with a forward-looking emphasis. The article begins with the general phenomenology of neutrino oscillations in vacuum and matter and documents the experimental evidence for oscillations of solar, reactor, atmospheric and accelerator neutrinos. Both active and sterile oscillation possibilities are considered. The impact of cosmology (BBN, CMB, leptogenesis) and astrophysics (supernovae, highest energy cosmic rays) on neutrino observables and vice versa, is evaluated. The predictions of grand unified, radiative and other models of neutrino mass are discussed. Ways of determining the unknown parameters of three-neutrino oscillations are assessed, taking into account eight-fold degeneracies in parameters that yield the same oscillation probabilities, as well as ways to determine the absolute neutrino mass scale (from beta-decay, neutrinoless double-beta decay, large scale structure and Z-bursts). Critical unknowns at present are the amplitude of ν_μto ν_e oscillations and the hierarchy of the neutrino mass spectrum; the detection of CP violation in the neutrino sector depends on these and on an unknown phase. The estimated neutrino parameter sensitivities at future facilities (reactors, superbeams, neutrino factories) are given. The overall agenda of a future neutrino physics program to construct a bottom-up understanding of the lepton sector is presented.

description: With the high increases in the uses of calcium hydroxide in various applications due its distinctive properties, human exposure has increased to normal- and nano-calcium hydroxide. However, its impact on the DNA integrity, expression of inflammatory cytokines, and induction of oxidative stress has not been clearly studied. Therefore, here we estimate the induction of DNA damage, inflammation, and oxidative stress in mice orally administrated a single dose (100 mg/kg) of normal- or nano-sized calcium hydroxide for 24 hour. Comet, Diphenylamine and laddered DNA fragmentation assays were done to assess DNA damage induction. Acute oral administration of normal- or nano-calcium hydroxide particles disrupted the DNA integrity, caused generation of ROS and also concurrent increases in both the nitric oxide concentration and inducible nitric oxide synthase gene expression in a reverse proportional to the calcium hydroxide particles' size. Increases in the concentration of calcium ions as well as alterations in the expression level of p53 and proinflammatory cytokines were also observed in calcium hydroxide administrated groups. Moreover, administration of normal- or nano-calcium hydroxide particles suspension elevated the level of malondialdehyde and decreased both the glutathione peroxidase activity and the reduced glutathione level, as well as caused tissue injuries (e.g. renal tube degeneration, congested blood vessels, atrophied lymphoid follicles, interstitial inflammatory reaction, and hyalinosis of myocardial muscles). Thus, we conclude that calcium hydroxide acutely orally administrated in its ordinary or nano-particulate form causes DNA damage induction by generating free radicals and altering the expression levels of p53 gene and proinflammatory cytokines.

description: The central object of investigation of this paper is the Hirzebruch class, a deformation of the Todd class, given by Hirzebruch (for smooth varieties) in his celebrated book "Topological Methods in Algebraic Geometry". The generalization for singular varieties is due to Brasselet-Schürmann-Yokura. Following the work of Weber, we investigate its equivariant version for (possibly singular) toric varieties. The local decomposition of the Hirzebruch class to the fixed points of the torus action and a formula for the local class in terms of the defining fan are mentioned. After this review part, we prove the positivity of local Hirzebruch classes for all toric varieties, thus proving false the alleged counterexample given by Weber.

description: Historicamente, o mercado agrícola tem sido caracterizado por grandes variações nos preços dos produtos, o que possibilita a transferência de renda entre os elos das cadeias agroindustriais envolvidos, tais como produtores rurais, atacadistas, varejistas e consumidores. Neste cenário inclui-se o setor suinícola nacional, que nos últimos anos apresentou crescimento tanto no mercado externo, como no mercado interno, gerando divisas para a economia nacional. Diante do problema de transferência de renda e tendo em vista a importância da produção de suínos como gerador de renda e fixador de mão de obra no campo, o presente trabalho através de modelos econométricos e utilizando séries de preços cotadas pelo CEPEA/ESALQ/USP entre 2004 e 2005, tem por objetivo analisar a intensidade e a duração com que as oscilações de preços são transmitidas do consumidor ao produtor no estado de São Paulo. Os resultados indicaram que variações semanais nos preços da carne suína no varejo impactam contemporaneamente os preços do quilo do suíno vivo recebidas pelos produtores, porém, essas variações não são transmitidas integralmente, apenas uma pequena parcela.
Relighting Humans: Occlusion-Aware Inverse Rendering for Full-Body Human Images

description: Relighting of human images has various applications in image synthesis. For relighting, we must infer albedo, shape, and illumination from a human portrait. Previous techniques rely on human faces for this inference, based on spherical harmonics (SH) lighting. However, because they often ignore light occlusion, inferred shapes are biased and relit images are unnaturally bright particularly at hollowed regions such as armpits, crotches, or garment wrinkles. This paper introduces the first attempt to infer light occlusion in the SH formulation directly. Based on supervised learning using convolutional neural networks (CNNs), we infer not only an albedo map, illumination but also a light transport map that encodes occlusion as nine SH coefficients per pixel. The main difficulty in this inference is the lack of training datasets compared to unlimited variations of human portraits. Surprisingly, geometric information including occlusion can be inferred plausibly even with a small dataset of synthesized human figures, by carefully preparing the dataset so that the CNNs can exploit the data coherency. Our method accomplishes more realistic relighting than the occlusion-ignored formulation.

description: We performed VLA observations of the 22 GHz H2O maser emission in the merging galaxy NGC6240, which hosts the well-known double active nuclei. In a previous paper, we reported on the first solid detection of the H2O maser emission in 2001. After two abortive attempts due to the weakness and probable variability of the emission, the maser was detected with the VLA in June 2002. The emission is unresolved at ~ 0.3 arcsecond and coincides with the southern 22 GHz continuum peak to ~ 0.007 arcsecond (~ 3 pc: D = 97 Mpc). The detection of the maser in the southern nucleus indicates that nuclear activity of the galaxy,which is significant in X-ray and far-infrared (FIR) bands, lies mainly in the southern nucleus, and the nucleus without a high brightness peak could be explained by thick dust emitting FIR radiation. We favour the idea that the maser in NGC6240 is associated with the AGN-activity.

description: Tobacco products contain thousands of chemicals, including addictive and toxic chemicals. We utilized in silico toxicology tools to predict in a validation test and in a separate screening test, the mutagenic potential of chemicals reported in tobacco products and tobacco smoke. Different publicly available (quantitative) structure-activity relationship (Q)SAR software platforms were used in this study. The models were validated against 900 chemicals relevant to tobacco for which experimental Ames mutagenicity data are available from public sources. The predictive performance of the individual and combined (Q)SAR models was evaluated using various performance metrics. All the (Q)SAR models represented >95% of the tobacco chemical space indicating a high potential for screening tobacco products. All the models performed well and predicted mutagens and nonmutagens with 75-95% accuracy, 66-94% sensitivity and 73-97% specificity. Subsequently, in a screening test, a combination of complementary SAR-based and QSAR-based models was used to predict the mutagenicity of 6820 chemicals catalogued in tobacco products and/or tobacco smoke. More than 1200 chemicals identified in tobacco products are predicted to have mutagenic potential, with 900 potential mutagens in tobacco smoke. This research demonstrates the validity of in silico (Q)SAR tools to make mutagenicity predictions for chemicals in tobacco products and/or tobacco smoke, and suggest they hold utility as screening tools for hazard identification to inform tobacco regulatory science.

description: We study the manifestation of the Nernst effect in the Corbino disk subjected to the normal external magnetic field and to the radial temperature gradient. The Corbino geometry offers a precious opportunity for the direct measurement of the magnetization currents that are masked by kinetic contributions to the Nernst current in the conventional geometry. The magnetization currents, also referred to as the edge currents, are independent on the conductivity of the sample which is why they can be conveniently described within the thermodynamic approach. They can be related to the Landau thermodynamic potential for an infinite system. We demonstrate that the observable manifestation of this, purely thermodynamic, Nernst effect consists in the strong oscillations of the magnetic field measured in the center of the disk as a function of the external field. The oscillations depend on the temperature difference at the edges of the disk. Dirac fermions and 2D electrons with a parabolic spectrum are characterized by oscillations of different phase and frequency. We predict qualitatively different power dependencies of the magnitude of the Nernst signal on the chemical potential for normal and Dirac carriers.

description: This article investigates how information from cotton yield monitors influences the perceptions of within-field yield variability of cotton producers. Using yield distribution modeling techniques and survey data from cotton producers in 11 southeastern states, we find that cotton farmers who responded to the survey tend to underestimate within-field yield variability (by approximately 5–18%) when not using site-specific yield monitor information. Results further indicate that surveyed cotton farmers who responded to a specific question about yield monitors place a value of approximately $20/acre/year (on average) on the additional information about within-field yield variability that the yield monitor technology provides.

description: We have carried out Raman spectroscopy experiments to investigate two-magnon excitations in epitaxial thin films of the quasi-two-dimensional antiferromagnetic Mott insulator Sr$_2$IrO$_4$ under in-plane misfit strain. With in-plane biaxial compression, the energy of the two-magnon peak increases, and the peak remains observable over a wider temperature range above the Néel temperature, indicating strain-induced enhancement of the superexchange interactions between $\it{J}_{eff}$ = 1/2 pseudospins. From density functional theory calculations, we have found an increase of the nearest-neighbor hopping parameter and exchange interaction with increasing biaxial compressive strain, in agreement with the experimental observations. Our experimental and theoretical results provide perspectives for systematic, theory-guided strain control of the primary exchange interactions in 5$\it{d}$ transition metal oxides.

description: Protection against liver injury and its consequences is considered an essential issue to minimize the number of annual deaths caused by liver diseases. The present study was designed to evaluate the potential role of pomegranate extract (PE) and/or curcumin in the regression of thioacetamide (TAA)-induced liver fibrosis, focusing on their modulatory effects on Nrf2/HO-1, NF-κB, and TGF-β/Smad3 signaling pathways. Liver fibrosis was induced in male Wistar rats by intraperitoneal injection of TAA (100 mg/kg) three times a week, for 8 weeks. To assess the protective effects of PE and/or curcumin against TAA-induced liver fibrosis, rats were treated on a daily basis with oral doses of PE (200 mg/kg) and/or curcumin (200 mg/kg) for 8 weeks. The results indicated that PE and/or curcumin attenuated TAA-induced liver fibrogenesis, as evidenced by a significant improvement in the liver function tests (AST, ALT, ALP, and albumin), oxidative stress biomarkers (MDA, SOD, and GSH), and inflammatory biomarkers (NF-ĸB, TNF-α, IL-1β, iNOS, TGF-β, and MPO), compared to TAA group. Moreover, treatment with PE and/or curcumin exerted a significant upregulation of Nrf2/HO-1 gene expressions along with significant downregulation of NF-ĸB, TGF-β, and phospho-Smad3 protein expressions, as well as α-SMA and collagen-1 gene expressions. The histopathological examination has corroborated these findings. In conclusion, hepatoprotective activities of PE and/or curcumin could be linked to their abilities to modulate Nrf2/HO-1, NF-κB, and TGF-β/Smad3 signaling pathways. It is worth noting that the combination of PE and curcumin exerted superior hepatoprotective effects against TAA-induced liver fibrosis, as compared to monotherapy.

description: We propose and study a set of algorithms for discovering community structure in networks -- natural divisions of network nodes into densely connected subgroups. Our algorithms all share two definitive features: first, they involve iterative removal of edges from the network to split it into communities, the edges removed being identified using one of a number of possible "betweenness" measures, and second, these measures are, crucially, recalculated after each removal. We also propose a measure for the strength of the community structure found by our algorithms, which gives us an objective metric for choosing the number of communities into which a network should be divided. We demonstrate that our algorithms are highly effective at discovering community structure in both computer-generated and real-world network data, and show how they can be used to shed light on the sometimes dauntingly complex structure of networked systems.

description: Noncommutative U(1) gauge theory in 4-dimensions is shown to be equivalent in some scaling limit to an ordinary non-linear sigma model in 2-dimensions . The model in this regime is solvable and the corresponding exact beta function is found. We also show that classical U(n) gauge theory on {R}^{d-2}{\times}{R}^2_θ can be approximated by a sequence of ordinary (d-2)-dimensional Georgi-Glashow models with gauge groups U(n(L+1)) where L+1 is the matrix size of the regularized noncommutative plane {R}^2_θ.

description: We obtain new semiclassical estimates for pseudodifferential operators with low regular symbols. Such symbols appear naturally in a Cauchy Problem related to recent weak solutions to the unstable Muskat problem constructed via convex integration in [CCF16]. In particular, our new estimates reveal the tight relation between the speed of opening of the mixing zone and the regularity of the interphase.

description: The present study aims to assess the influences of oral Methylphenidate on kidney function and structure versus vehicle treatment in adult male rats. In this study, thirty adult male rats equally into two treatment groups divided randomly, and among them, MPH has been administered for 21 days, at doses of 20 mg/kg, and the control group has received salin. In renal, under the effect of MPH applying quantitative real-time PCR, we analyzed nephrotoxicity-related molecular pathways like autophagy, inflammation, and apoptosis. Moreover, the levels of GSH, CAT, and SOD were investigated as antioxidant enzymes. Afterward, stereological analysis in MPH-treated rats has been performed. Analysis of qPCR displayed inflammation, impaired autophagy, and enhanced apoptosis with histological changes in the kidney's tissue, also an important rise in the antioxidant enzymes’ level. Besides, 20 mg/kg of MPH led to a decline in the mean of Bowman’s space thickness and renal corpuscle’s volume in comparison to the control rats. Collectively, our histological and molecular data implicit that in the kidney region, administrating of MPH evoked discriminative expression alterations in nephrotoxicity-associated signaling cascades, specifically autophagy, inflammation, and apoptosis paired with important damage to kidney tissue.

description: Recent analysis of the combined data of cosmic microwave background, galaxy clustering and supernovae type Ia observations have set strong constraints on the equation of state parameter $w_X$. The upper bound $w_X < -0.82$ at 95% c.l. rules out an important class of models, the domain walls ($-2/3 < w_X < -1/3$). Here we revisit the issue of domain walls as a possible alternative to the standard $Λ$-CDM model by questioning the assumptions made in the choice of priors of the data analysis. The results of our investigation show that domain walls can provide a good fit to the WMAP data for a different choice of priors with ``lower'' values of the Hubble parameter ($h<0.65$), (as indicated by Sunyaev-Zeldovich and time delays for gravitational lensing observations), and ``higher'' values of the matter density ($Ω_m > 0.35$), (in agreement with recent measurements of the temperature-luminosity relation of distant clusters observed with the XMM-Newton satellite). In this new perspective, their existence would lead to important implications for the CMB constraints on cosmological and inflationary parameters.

description: The effectiveness of the Expanded Food and Nutrition Education Program in achieving its goals at the national, regional, and state level is unknown. Using US Department of Agriculture (USDA) data from all states and territories for the years 2000–2006, the impact of program and participant characteristics and returns to scale on the three outcome indicators used by the USDA are estimated. Program and participant characteristics do not seem to be as important as the amount of money spent on the program. Generally speaking, there are constant and increasing returns to scale for two of the three federal outcome indices for most states but not all.

description: 3-dimensional (3D) cell cultures are being increasingly recognized as physiologically more relevant in vitro models than traditional monolayer cultures, because they better mimic in vivo like microenvironment, cell-cell and cell-extracellular matrix interactions. Nevertheless, the broader use of 3D models might be limited by requirements for special consumables, equipment, or skills for 3D cell cultures, and by their limited throughput and scalability. In this study, we optimized and adapted a commercially available agarose-micromolding technique to produce scaffold-free spheroid cultures. Brightfield microscopy was used for routine non-destructive and non-invasive evaluation of spheroid formation and growth. The workflow is compatible with manual, as well as high speed automated microscopic image acquisition, and it is supplemented with an in-house developed macro ‘Spheroid_Finder’ for open source software Fiji to facilitate rapid automated image analysis. This protocol was used to characterize and quantify spheroid formation and growth of two different hepatic cell lines, hTERT immortalized, but non-tumorigenic, adult human liver stem cell line HL1-hT1, and human hepatocellular carcinoma cell line HepG2, as well as their responses to a model antiproliferative and cytotoxic agent, 5-fluorouracil. The complete protocol provides a simple and ready-to-use solution to initiate scaffold-free spheroid cultures in any laboratory with standard equipment for mammalian in vitro cell culture work. Thus, it allows to increase throughput and scale of spheroid culture experiments, which can be greatly utilized in different areas of biomedical, pharmaceutical and toxicological research.

description: We demonstrate a new mechanical transduction platform for individual spin qubits. In our approach, single micro-magnets are trapped using a type-II superconductor in proximity of spin qubits, enabling direct magnetic coupling between the two systems. Controlling the distance between the magnet and the superconductor during cooldown, we demonstrate three dimensional trapping with quality factors around one million and kHz trapping frequencies. We further exploit the large magnetic moment to mass ratio of this mechanical oscillator to couple its motion to the spin degree of freedom of an individual nitrogen vacancy center in diamond. Our approach provides a new path towards interfacing individual spin qubits with mechanical motion for testing quantum mechanics with mesoscopic objects, realization of quantum networks, and ultra-sensitive metrology.

description: We have studied the magnetic properties of Ba_2FeNbO_6 and Ba_2MnNbO_6. it is seen that Ba_2FeNbO_6 is an antiferromagnet with a weak ferromagnetic behaviour at 5K while Ba_2MnNbO_6 shows two magnetic transitions one at 45 K and the other at 12K. Electron spin resonance (ESR) measurements at room temperature show that the Mn compound does not show any Jahn-Teller distortion. It is also seen that the Neel temperature of the A_2FeNbO_6 (A=Ba,Sr, BaSr) compounds do not vary significantly. However variations in the average A-site ionic radius influence the formation of short range correlations that persist above T_N.

description: Protection against liver injury and its consequences is considered an essential issue to minimize the number of annual deaths caused by liver diseases. The present study was designed to evaluate the potential role of pomegranate extract (PE) and/or curcumin in regression of thioacetamide (TAA)-induced liver fibrosis, focusing on their modulatory effects on Nrf2/HO-1, NF-κB, and TGF-β/Smad3 signaling pathways. Liver fibrosis was induced in male Wistar rats by intraperitoneal injection of TAA (100 mg/kg) three times a week, for 8 weeks. To assess the protective effects of PE and/or curcumin against TAA-induced liver fibrosis, rats were treated on a daily basis with oral doses of PE (200 mg/kg) and/or curcumin (200 mg/kg) for 8 weeks. The results indicated that PE and/or curcumin attenuated TAA-induced liver fibrogenesis, as evidenced by significant improvement in the liver function tests (AST, ALT, ALP, and albumin), oxidative stress biomarkers (MDA, SOD, and GSH), and inflammatory biomarkers (NF-ĸB, TNF-α, IL-1β, iNOS, TGF-β, and MPO), compared to TAA group. Moreover, treatment with PE and/or curcumin exerted a significant upregulation of Nrf2/HO-1 gene expressions along with significant downregulation of NF-ĸB, TGF-β, and phospho-Smad3 protein expressions, as well as α-SMA and collagen-1 gene expressions. The histopathological examination has corroborated these findings. In conclusion, hepatoprotective activities of PE and/or curcumin could be linked to their abilities to modulate Nrf2/HO-1, NF-κB, and TGF-β/Smad3 signaling pathways. It is worth noting that the combination of PE and curcumin exerted superior hepatoprotective effects against TAA-induced liver fibrosis, as compared to monotherapy.

description: The emerging light from a galaxy is under the influence of its own interstellar medium, as well as its spatial orientation. Considering a sample of 2,239 local spiral galaxies in optical (SDSS u, g, r, i, and z) and infrared bands (WISE W1, W1), we study the dependency of the global intrinsic attenuation in spiral galaxies on their morphologies, sizes, and spatial inclinations. Reddening is minimal at the extremes of low mass and gas depletion and maximal in galaxies that are relatively massive and metal-rich and still retain substantial gas reserves. A principal component constructed from observables that monitor galaxy mass, relative HI content to old stars, and infrared surface brightness is strongly correlated with the amplitude of obscuration. We determine both a parametric model for dust obscuration and a non-parametric model based on the Gaussian process formalism. An average dust attenuation curve is derived for wavelengths between 0.36 and 4.5 microns.

description: This paper fills the gap of modeling positive externality cases when private marginal cost is higher than social marginal cost. Within this unique type of divergence of marginal costs two cases are scrutinized: social marginal benefit being higher than private marginal benefit, and vice versa, social marginal benefit being lower than private marginal benefit. Empirical case in study is commercial shellfish farming firm on the West Coast. The study shows that contrary to popular beliefs correcting for positive externalities does not always result in a positive welfare; however, it does result in a positive welfare for the study case of the particular shellfish farm.
