description: A migração campo-cidade ainda é reconhecida por muitos como o resultado inequívoco da deterioração social e ambiental no meio rural decorrentes da reordenação latifundiária ou, no Nordeste brasileiro, do advento das Secas. Sem alternativas, as famílias são obrigadas a migrar. Os cientistas sociais não raro aludem ao fenômeno do “êxodo rural” para caracterizar a perene e volumosa transferência do homem do interior para a cidade grande. Contudo, uma investigação mais acurada levanta contestações à esta hipótese como explicação para a urbanização acelerada do país no século XX. Embora menos romântico que a primeira explicativa, as famílias decidem migrar para melhorar de vida. Enxergam a cidade como alternativa para escapar da pobreza atávica de seu meio. Não se trata de um expulsionismo determinista, mas um atrativismo possibilista o que prepondera a médio e longo prazo. Neste sentido, procura-se enfocar a questão durante a segunda metade do século XX, aplicada a Pernambuco, tomando-o como emblemático para outros estados brasileiros, inclusive para a migração inter-regional. Como será demonstrado, muito embora a imagem do retirante da seca ainda se constitua a típica representação do homem migrante nordestino - ao encontro do imaginário urbano-burguês – são a roda do trem, o chão da fábrica, o emprego doméstico, as luzes da cidade, as economias de aglomeração urbana, os determinantes principais da mudança de contingentes populacionais tão grandes.

description: We assess the role of a resonant spectrum in the AdS instability, and quantify the extent to which breaking the resonant spectrum of AdS can restore stability. Specifically, we study non-collapsing `multi-oscillator' solutions in AdS under various boundary conditions that allow for both resonant and non-resonant spectra. We find non-collapsing two mode, equal amplitude solutions in the non-resonant Robin case, and that these solutions vanish in the fully resonant Dirichlet case. This is consistent with non-resonant stability, and with the idea that stable solutions in the Dirichlet case are all single-mode dominated. Surprisingly, when the boundary condition is Neumann, we find non-collapsing solutions arbitrarily close to AdS that are not single-mode dominated, despite the spectrum being fully resonant.

description: There is a pressing need for a robust rating scale for ocular myasthenia gravis (OMG). Rating scales for myasthenia gravis (MG) research have a predominant focus on generalised disease. We present results of the first dedicated rating scale for OMG: the ocular myasthenia gravis rating scale (OMGRate). The OMGRate was developed through an international collaboration between neuromuscular and neuro-ophthalmology experts in OMG. It comprises two components: a physician- examination (OMGRate-e) and a patient questionnaire (OMGRate-q).. The OMGRate was prospectively validated in patients attending a neuro-ophthalmology clinic from April 2017 to October 2018. External validity and reliability of OMGRate were evaluated using validated MG rating scales: the Myasthenia Gravis Composite (MGC), the Myasthenia Gravis Quality of Life (MG-QOL), and the ocular component from the Myasthenia Gravis Impairment Index questionnaire (MGII). Two hundred and eleven assessments were completed in 104 patients (67 males, mean age 55 y, range 18–86 y). There was very good external validity of the OMGRate: good correlation between OMGRate-e and MGC (r = 0.64, 95% confidence intervals [CI] 0.54–0.74, p < .0001); excellent correlation between OMGRate-q and MGII (r = 0.85, 95% CI 0.78–0.91, p < .0001) and good correlation between OMGRate and MG-QOL (r = 0.68, 95% CI 0.60–0.77, p < .0001). A higher correlation of OMGRate and MG-QOL compared with MGC and MG-QOL (r = 0.47, 95% CI 0.34–0.59, p < .0001) suggests that OMGRate is better able to capture significant QOL information in patients with OMG. It had excellent reliability with an intraclass correlation coefficient of 0.83 (95% CI 0.67–0.92). Feedback from examiners and patients indicated that the OMGRate was easy to use. In conclusion, OMGRate is an easy-to-use, valid and reliable rating scale for monitoring the severity of OMG.

description: We report on the serendipitous discovery of a new X-ray source, SAX J1802.7-2017, ~22' away from the bright X-ray source GX 9+1, during a BeppoSAX observation of the latter source on 2001 September 16-20. SAX J1802.7-2017 remained undetected in the first 50 ks of observation; the source count rate in the following ~300 ks ranged between 0.04 c/s and 0.28 c/s, corresponding to an averaged 0.1-10 keV flux of 3.6 10^{-11} ergs cm^{-2} s^{-1}. We performed a timing analysis and found that SAX J1802.7-2017 has a pulse period of 139.612 s, a projected semimajor axis of a_x sin i ~ 70 lt-s, an orbital period of ~4.6 days, and a mass function f(M) ~ 17 Msun. The new source is thus an accreting X-ray pulsar in a (possibly eclipsing) high mass X-ray binary. The source was not detected by previous X-ray astronomy satellites, indicating that it is likely a transient system.

description: The vestibular and oculomotor/visual systems are commonly affected in post-concussion syndrome (PCS). Convergence insufficiency (CI) is the most common ocular abnormality after concussion. Electrovestibulography (EVestG) is a relatively new non-invasive method that measures the peripheral vestibular responses; it has shown abnormal vestibular responses in a PCS. Here, we report the results of investigating the correlation between the vestibular and oculomotor systems in PCS population using EVestG and CI measures. Forty-eight PCS patients were tested using EVestG, out of which 20 also completed the Rivermead post-concussion questionnaire (RPQ). An EVestG feature (Field Potential (FP)-area) was extracted from the stationary part of the EVestG signals. A neuro-ophthalmologist (author BM) measured participants’ CI at near vision using cross-cover examination and a prism-bar. Results indicate: (1) vestibular abnormality (i.e. FP-area) and CI values are significantly correlated in PCS (R = 0.68, p < .01), and (2) there are significant correlations between severity of concussion (i.e. RPQ3) and CI (R = 0.70, p < .01) and between RPQ3 and FP-area (R = −0.56, p < .02). To the best of our knowledge, this is the first study that objectively demonstrates a significant positive correlation between the CI and vestibular systems’ abnormality. These findings are scientifically important as they help localise the pathology of PCS, and are clinically valuable as they help physicians in their decision-making about PCS diagnosis and rehabilitation strategies.

description: Additional file 4: Figure S3. Comparison of QC Metrics in cases to controls. We detected 24 species across all control samples after initial filtering. Environmental metagenomic samples are qualitatively similar to samples of laboratory contamination so filtering based on controls is non-trivial. We compared the number of unique marker k-mers found for each taxa in each case sample to the maximum number found in one control (A) and, analogously, the total number of reads (B). We took all taxonomic assignments with a read ratio greater than 2 and a k-mer ratio greater than 5 (C). If a taxonomic assignment met both criteria in at least two samples, it was permitted (red taxa on bottom right) otherwise the taxa was filtered from all assignments (blue taxa on bottom right).

description: When using input-output analysis to measure the effect of exogenous changes in the value of final demand, it is important to identify the degree to which the change in value is due to changes in prices or to changes in the volume of demand. A modified input-output model is presented to incorporate changes in prices as well as changes in the volume of final demand. The empirical results demonstrate that changes in the volume of final demand stimulate output and income directly, while changes in price have no effect on output but do influence income levels.

description: Superconductor-ferromagnet-superconductor Josephson junctions are known to exist in the $0$ and $π$ states with the transitions between them controlled by the temperature and ferromagnetic interlayer thickness. We demonstrate that these transitions can be controlled also by the external magnetic field directed perpendicular to the layers. By varying the ratio of diffusion coefficients in superconducting and ferromagnetic layers, these field-controlled transitions can be made detectable for arbitrary large value of the exchange energy in the ferromagnet. We also show that the $0$-$π$ transitions in the perpendicular field can be observed as the specific features of the flux-flow conductivity dependencies on the ferromagnetic thickness in accordance with recent experimental results.

description: The authors propose six questions relevant to the evaluation of all social system models, and apply them to the Barr-Gale model for forecasting the Consumer Price Index for Food. While analysts invest much effort in developing new economic models, relatively little attention is paid to critiquing existing models. For models to become scientifically acceptable and widely used tools for policy design in the social sciences, they must be accompanied by complete documentation and data. Then independent investigators can confirm published results and determine a model's sensitivity to changes in assumptions. Greater emphasis on critical analysis and standard procedures for evaluation will help potential users evaluate models for accuracy and suitability for their purposes.

The convergence regions of the new series contain regions of interest to physical problems. These include some ranges of masses and squared external momentum values which make them useful from Chiral Perturbation Theory to some regions of the parameter space of the Minimal Supersymmetric Standard Model. The analytic continuation results presented on the Lauricella series could be used in other settings as well.

description: Unique solutions are more difficult to guarantee for commodity models that have nonlinear simultaneous equations than for those with linear ones. The nonlinear case requires determination of uniqueness before a solution is attempted while uniqueness in the linear case is determined as a byproduct of the solution procedure. Unique solutions are important because they are necessary for unambiguous results (that is, results that can always be duplicated). This article explains an approach for guaranteeing unique solutions for commodity models specified with a nonlinear equation type often used in economics, the constant-elasticity equation. This choice allows researchers the option of using secondary data sources (parameter estimates) in developing commodity models.

description: Brown dwarfs bridge the gap between the stellar and planetary mass regimes. Evolving from conditions very similar to the lowest-mass stars, the atmospheres of older brown dwarfs closely resemble those expected in close-in extrasolar giant planets, and with cooler BDs still being discovered, more and more approach the properties of gas giants at wider separation. Interpreting the spectra of BDs is therefore a crucial step towards understanding and predicting the spectral and thermal properties of EGPs. Essential properties of substellar atmospheres are massive molecular line-blanketing and the condensation of species with decreasing Teff, changing the chemical equilibrium composition and causing absorption from dust grains. More complex details involve the distribution of dust clouds over the surface giving rise to temporal variability, and possible deviations from chemical equilibrium conditions. In the case of close-in EGPs and some BDs in binary systems, the effect of irradiation from the primary significantly affects the spectral properties and thermal evolution.

description: The optical beam splitter is a widely-used device in photonics-based quantum information processing. Specifically, linear optical networks demand large numbers of beam splitters for unitary matrix realization. This requirement comes from the beam splitter property that a photon cannot go back out of the input ports, which we call "directionally-biased". Because of this property, higher dimensional information processing tasks suffer from rapid device resource growth when beam splitters are used in a feed-forward manner. Directionally-unbiased linear-optical devices have been introduced recently to eliminate the directional bias, greatly reducing the numbers of required beam splitters when implementing complicated tasks. Analysis of some originally directional optical devices and basic principles of their conversion into directionally-unbiased systems form the base of this paper. Photonic quantum walk implementations are investigated as a main application of the use of directionally-unbiased systems. Several quantum walk procedures executed on graph networks constructed using directionally-unbiased nodes are discussed. A significant savings in hardware and other required resources when compared with traditional directionally-biased beam-splitter-based optical networks is demonstrated.

description: In an examination of the literature of agricultural economics from the fifties on, the author presents several definitions of production capacity of U.S. agriculture. No satisfactory measure of such capacity exists nor is there a viable, generally acceptable definition of the term. Literature of the nonagricultural sector contains some appropriate definitions and methodologies associated with capacity measurement. After discussing and evaluating several of these, the author suggests that some of them may provide help in making agricultural methods more useful.

description: Off-diagonal long-range order (ODLRO) is a quantum phenomenon not describable in classical mechanical terms. It is believed to be one characteristic of superconductivity. The quantum state constructed by eta-pairing which demonstrates ODLRO is an eigenstate of the three-dimensional Hubbard model. Entanglement is a key concept of the quantum information processing and has no classical counterpart. We study the entanglement property of eta-pairing quantum state. The concurrence is a well-known measure of quantum entanglement. We show that the concurrence of entanglement between one-site and the rest sites is exactly the correlation function of the ODLRO for the eta-pairing state in the thermodynamic limit. So, when the eta-pairing state is entangled, it demonstrates ODLRO and is thus in superconducting phase, if it is a separable state, there is no ODLRO. In the thermodynamic limit, the entanglement between M-site and other sites of the eta-pairing state does not vanish. Other types of ODLRO of eta-pairing state are presented. We show that the behavior of the ODLRO correlation functions is equivalent to that of the entanglement of the eta-pairing state. The scaling of the entropy of the entanglement for the eta-pairing state is studied.

The contributions to the energy release from different particle species and energies as well as the typical particle densities are investigated. Special care is taken of particles falling below the energy threshold of the simulation which contribute about 10% to the total energy deposition. The dominant contribution to the total deposition stems from electrons and positrons from sub-MeV up to a few hundred MeV, with typical transverse distances between particles exceeding 1 mm for 10 EeV showers.

description: We study the dynamics of domain walls (DWs) in a metallic, ferromagnetic nanowire. We develop a Keldysh collective coordinate technique to describe the effect of conduction electrons on rigid magnetic structures. The effective Lagrangian and Langevin equations of motion for a DW are derived. The DW dynamics is described by two collective degrees of freedom: position and tilt-angle. The coupled Langevin equations therefore involve two correlated noise sources, leading to a generalized fluctuation-dissipation theorem (FDT). The DW response kernel due to electrons contains two parts: one related to dissipation via FDT, and another `inertial' part. We prove that the latter term leads to a mass for both degrees of freedom, even though the intrinsic bare mass is zero. The electron-induced mass is present even in a clean system without pinning or specifically engineered potentials. The resulting equations of motion contain rich dynamical solutions and point toward a new way to control domain wall motion in metals via the electronic system properties. We discuss two observable consequences of the mass, hysteresis in the DW dynamics and resonant response to ac current.

There were 406 survey participants with an estimated survey response rate of 18%. Ninety-four per cent of North American practitioners preferred TABx compared with 74% of their European counterparts. Two per cent of North American practitioners preferred Doppler US versus 24% of European physicians. Regional differences were statistically significant (p < .001).

description: Traboulsi syndrome is a rare autosomal recessive genetic disorder. The present study aimed to identify the pathogenic variants in the ASPH gene responsible for a rare and unique presentation of Traboulsi syndrome associated with cardiac disorder. DNA was isolated from the blood samples from 3 clinically diagnosed Traboulsi syndrome patients (n = 3) after obtaining a prior-informed consent. All three had classical ocular and facial dysmorphic features, and two of them also had associated cardiac problems. Mutation screening was performed for the exons of ASPH gene by Sanger sequencing in these patients and 350 controls. Sequence data analysis was performed using Seqscape and insilico protein analysis by SIFT, PyMOL, and Dynamut softwares. A novel homozygous variant(c.1853 T > A) in exon 21 was identified by Sanger sequencing in two of the three cases while a known pathogenic variant in exon 25 was identified in the third proband. The novel nonsense variant in exon 21 results in a premature truncation of gene resulting in a protein of 543 amino acids. This variant is not reported in ExAC, dbSNP and 1000 genome databases. Both the patients harboring this novel variant, had a unique presentation of Traboulsi syndrome with cardiac dysfunction. In silico analysis predicted the mutation to affect the calcium-binding activity of the gene which might explain the associated cardiac dysfunction in these two patients. The novel pathogenic mutation displayed a perfect genotype-phenotype correlation in two probands of Traboulsi syndrome with cardiac dysfunction.

The Minkowski 4-vector character of space-time elements as well as the key properties of special relativity are still the same as in the standard theory. However, the new topological structure allows the possibility of an intrinsic asymmetry in the time evolution of physical systems.

description: We report the specific heat and entropy of single crystals of the spin ice compound Dy2Ti2O7 at temperatures down to 0.35 K. We apply magnetic fields along the four characteristic directions: [100], [110], [111] and [112]. Because of Ising anisotropy, we observe anisotropic release of the residual zero-point entropy, attributable to the difference in frustration dimensionality. In the high magnetic field along these four directions, the residual entropy is almost fully released and the activation entropy reaches Rln2. However, in the intermediate field region, the entropy in fields along the [111] direction is different from those for the other three field directions. For the [111] direction the frustration structure changes from that of three-dimensional(3D) pyrochlore to that of two-dimensional(2D) Kagome-like lattice with constraint due to the ice rule, leading to different values of zero-point entropy.

description: The etiology of the inflammatory ON is multifactorial. Much attention is paid to the inflammatory and immune processes that are likely to contribute to the demyelination and MS development. IL-6, VEGFA, and TIMP-3 genes are thought to be involved in the inflammatory processes and manifestation of CNS demyelination, so we aimed to determine the relationship between VEGFA rs1413711, TIMP-3 rs9621532, IL-6 rs1800796 gene polymorphisms and ON, and ON with MS. Patients with ON, ON with MS, and a random sample of healthy population were enrolled. The genotyping of VEGFA rs1413711, TIMP-3 rs9621532, and IL-6 rs1800796 polymorphisms was carried out using the real-time polymerase chain reaction method. T/C and C/C genotypes of VEGFA rs1413711 were associated with about threefold increased odds of developing ON in the dominant and codominant models. Each allele C at VEGFA rs1413711 was associated with 1.7-fold increased odds of ON development. IL-6 rs1800796 allele C was more frequent in the ON with MS group compared to the control: 17.6% vs. 7.5%, respectively (p = .040). No statistically significant associations were found between TIMP-3 rs9621532 and the ON development. rs1413711 is associated with the ON development.

description: From the approximately $\sim$3,500 planetary nebulae (PNe) discovered in our Galaxy, only 14 are known to be members of the Galactic halo. Nevertheless, a systematic search for halo PNe has never been performed. In this study, we present new photometric diagnostic tools to identify compact PNe in the Galactic halo by making use of the novel 12-filter system projects, J-PLUS (Javalambre Photometric Local Universe Survey) and S-PLUS (Southern-Photometric Local Universe Survey). We reconstructed the IPHAS (Isaac Newton Telescope (INT) Photometric H$α$ Survey of the Northern Galactic Plane) diagnostic diagram and propose four new ones using i) the J-PLUS and S-PLUS synthetic photometry for a grid of photo-ionisation models of halo PNe, ii) several observed halo PNe, as well as iii) a number of other emission-line objects that resemble PNe. All colour-colour diagnostic diagrams are validated using two known halo PNe observed by J-PLUS during the scientific verification phase and the first data release (DR1) of S-PLUS and the DR1 of J-PLUS. By applying our criteria to the DR1s ($\sim$1,190 deg$^2$), we identified one PN candidate. However, optical follow-up spectroscopy proved it to be a H II region belonging to the UGC 5272 galaxy. Here, we also discuss the PN and two H II galaxies recovered by these selection criteria. Finally, the cross-matching with the most updated PNe catalogue (HASH) helped us to highlight the potential of these surveys, since we recover all the known PNe in the observed area. The tools here proposed to identify PNe and separate them from their emission-line contaminants proved to be very efficient thanks to the combination of many colours, even when applied -like in the present work- to an automatic photometric search that is limited to compact PNe.

description: We examine the effect of farm level cost and scale efficiencies on dairy quota exchanges in Ontario. A constrained profit maximization framework is used to illustrate the role of cost efficiency in quota exchanges (i.e., sales and purchases). Using a multinomial logit model, where net quota buyers and net quota sellers are identified our empirical results indicate that variations in cost efficiency do not have a significant effect on purchases milk production quota, whereas scale efficiency does. Younger farmers, farms with underutilized barns space and farms with a recent history of quota purchase tend to buy milk production quota.
Is the Initial Mass Function of Low Surface Brightness Galaxies Dominated by Low Mass Stars?

description: The rotation curves of low surface brightness (LSB) galaxies suggest that they possess significantly higher mass-to-light (M/L) ratios than their high surface brightness counterparts, indicating that LSB galaxies may be dark matter dominated. This interpretation is hampered by the difficulty of disentangling the disc and dark halo contributions from the disc dynamics of LSB galaxies. Recently, Fuchs (2002) has attempted such a disentanglement using spiral arm density wave and swing amplification theory, allowing an independent measurement of the disc mass; this work suggests that LSB discs are significantly more massive than previously believed. This would considerably reduce the amount of matter required in the dark halos in fitting the rotation curves. Interestingly, the high mass-to-light ratios derived for the discs appear inconsistent with standard stellar population synthesis models. In this paper, we investigate whether the high M/L ratios for the Fuchs LSB discs might be understood by adopting a very ``bottom heavy'' initial mass function (IMF). We find that an IMF with a power law exponent of around alpha=3.85 (compared to the standard Salpeter IMF, alpha=2.35) is sufficient to explain the unusually high M/L ratios of the Fuchs sample. Within the context of the models, the blue colours ((B-R)_0 < 1.0) of the sample galaxies result from being metal-poor ([Fe/H] = -1.5 ~ -1.0) and having undergone recent (~1-3 Gyr ago) star formation.

description: This article estimates the impact of social media exposure on consumer valuation of product characteristics. We apply the Berry, Levinsohn and Pakes (1995) model of market equilibrium to sales data for 18 carbonated soft drink brands sold in 12 cities over 17 months (June 2011 to October 2012) and social media conversations on Facebook, Twitter and YouTube. Empirical results show that social media exposure is a significant driver of consumer behavior through altering evaluation of product characteristics and purchase choices.

description: Heterozygous c.440 G > T mutation in the S-antigen visual arrestin (SAG) gene has been described as a cause of autosomal dominant retinitis pigmentosa (adRP) in a series of patients of Hispanic origin. This study presents the early and late clinical features and disease progression rates in an Australian family with SAG adRP. An observational case series of four family members with adRP. They were examined clinically, with multi-modal retinal imaging and electroretinography (ERG) to ascertain phenotype. Disease progression rate was measured using optical coherence tomography (OCT) and fundus autofluorescence (FAF). A retinal dystrophy panel was used for the proband and cascade testing with targeted Sanger sequencing was conducted in other available family members. The proband presented at 36 years of age with profoundly reduced full-field ERG responses despite a sector RP phenotype. This progressed to a classic RP pattern over several decades leaving a small residual island of central visual field. The horizontal span of the residual outer nuclear layer and the area of hyperautofluorescent ring contracted at a rate of 8–11% and 9–14% per year, respectively. DNA sequencing confirmed the segregation of SAG c.440 G > T mutation with disease. SAG adRP presents with a reduced full-field ERG response consistent with a rod-cone dystrophy in mid-life despite a sector RP phenotype. Centripetal progression of the disease into the macula can be tracked by OCT and FAF imaging.
