description: We present and analyze solutions of D=11 supergravity describing the ``near-horizon'' (i.e., asymptotically AdS_4 x S^7) geometry of M2-branes wrapped on surfaces of arbitrary genus. We study the forces experienced by test M2-branes in such backgrounds, and find evidence that extremal branes on surfaces of genera higher than the torus are unstable. Using the holographic connection between AdS spaces and superconformal field theories in the large N limit, we discuss the phases of the associated 2+1 dimensional theories. Finally, we also study the extension of these solutions to other branes, in particular to D2-branes.

description: Data and analysis methodology used for the SDSS/APOGEE Data Releases 13 and 14 are described, highlighting differences from the DR12 analysis presented in Holtzman (2015). Some improvement in the handling of telluric absorption and persistence is demonstrated. The derivation and calibration of stellar parameters, chemical abundances, and respective uncertainties are described, along with the ranges over which calibration was performed. Some known issues with the public data related to the calibration of the effective temperatures (DR13), surface gravity (DR13 and DR14), and C and N abundances for dwarfs (DR13 and DR14) are highlighted. We discuss how results from a data-driven technique, The Cannon (Casey 2016), are included in DR14, and compare those with results from the APOGEE Stellar Parameters and Chemical Abundances Pipeline (ASPCAP). We describe how using The Cannon in a mode that restricts the abundance analysis of each element to regions of the spectrum with known features from that element leads to Cannon abundances can lead to significantly different results for some elements than when all regions of the spectrum are used to derive abundances.

description: In this paper, we discuss multiscale methods for nonlinear problems. The main idea of these approaches is to use local constraints and solve problems in oversampled regions for constructing macroscopic equations. These techniques are intended for problems without scale separation and high contrast, which often occur in applications. For linear problems, the local solutions with constraints are used as basis functions. This technique is called Constraint Energy Minimizing Generalized Multiscale Finite Element Method (CEM-GMsFEM). GMsFEM identifies macroscopic quantities based on rigorous analysis. In corresponding upscaling methods, the multiscale basis functions are selected such that the degrees of freedom have physical meanings, such as averages of the solution on each continuum. This paper extends the linear concepts to nonlinear problems, where the local problems are nonlinear. The main concept consists of: (1) identifying macroscopic quantities; (2) constructing appropriate oversampled local problems with coarse-grid constraints; (3) formulating macroscopic equations. We consider two types of approaches. In the first approach, the solutions of local problems are used as basis functions (in a linear fashion) to solve nonlinear problems. This approach is simple to implement; however, it lacks the nonlinear interpolation, which we present in our second approach. In this approach, the local solutions are used as a nonlinear forward map from local averages (constraints) of the solution in oversampling region. This local fine-grid solution is further used to formulate the coarse-grid problem. Both approaches are discussed on several examples and applied to single-phase and two-phase flow problems, which are challenging because of convection-dominated nature of the concentration equation.

description: In this note we formulate and investigate theoretical uncertainties for high Q^2 deep inelastic heavy quark (charm, etc.) production rates which arise within collinear resummation techniques from variations of the a priori unknown charm input scale Q_0 of O(alpha_s) variable flavour number schemes. We show that Q_0 variations constitute a source of considerable theoretical uncertainty of present O(alpha_s) calculations within such schemes and we suggest to consider a scale optimization from higher order corrections. We also outline how the stability of the fixed order and collinearly resummed perturbation series for heavy quark production can be comparatively investigated by variation of Q_0.

description: The structural properties of Na2RuO3 under pressure are studied using density functional theory within the generalized gradient approximation (GGA). We found that one may expect a structural transition at ~ 3 GPa. This structure at the high-pressure phase is exactly the same as the low-temperature structure of Li2RuO3 (at ambient pressure) and is characterized by the P21/m space group. Ru ions form dimers in this phase and one may expect strong modification of the electronic and magnetic properties in Na2RuO3 at pressure higher than 3 GPa.

Multiculturalism or Assimilation? Refugees and Immigrants as Europeans
Creators: name: Bujalska, Katarzyna
Publisher: name: E- Revista de Estudos Interculturais
Year: 2021

description: Recent years have been characterized by the emergence of a large migration flow in the European Union (EU), which is mainly due to the emergence of an armed civil conflict in Syria, the expansion of the self-proclaimed Islamic State and the spread of conflicts in Syria. For this reason, thousands of immigrants want to reach Europe via the Mediterranean Sea or the Balkans. In fact, migratory movements have existed since very old times and are proceeding with the process of human evolution. Migratory movements are most often caused by economic, social, cultural, political or environmental issues. This new wave of refugees has posed a number of political, economic, social and cultural challenges in European countries. Therefore, the EU has been seeking a common position to maximize the effectiveness of the refugee reception policy. This has not been possible due to the position of some states who reject the distribution program of refugees over the European continent. In this context, the Convention on the status of crises (Geneva Convention of 1951) is very important, as it provides a legal framework for the regulation of refugees’ concepts and issues. The aim of this work is to discuss the legal regulations for refugees and immigrant’s political situation, as well as their integration and assimilation process in different countries. This article analyses the European case, with a special emphasis on the specific situation of Portugal and Poland, concerning the issue of refugees and how integration processes work. This choice was made due to the fact that there is no common policy for the integration of refugees in Europe, and as long as the measures of each country are in compliance with international law, different policies can be adopted.

Embora esse artigo não tenha abordado todos os aspectos possíveis para a compreensão dos espaços público e privado, o estudo dos editoriais nos permitiu pontuar questões pertinentes para pensarmos os fazeres que envolvem a lembrança, os campos da memória, as nossas concepções políticas e abre perspectivas de pesquisa e aspectos para reflexões sobre cultura política na região do Norte Pioneiro Paranaense.Estas possibilidades tornam-se interessantes e profícuas à luz das particularidades da região conhecida como Norte Pioneiro do Paraná, por esta ser marcada por uma cultura política nitidamente enleada por clientelismo, mandonismo, coronelismo, corrupção, promiscuidade entre o público e o privado e o patrimonialismo. Estes aspectos marcam as relações interpessoais e afetam a consolidação da democracia e a criação de espaços igualitários na região.

description: Using as a springboard the wide spectrum of Chinese racial groups and ethno-linguistic, “foreign”(sub)groups residing in the Celestial Empire, this study concentrates on the last one hundred and six years of Chinese history (1912-2018), thus analyzing howsome Chinese cities and/or regions, including the Macau Special Administrative Region of the People’s Republic of China,have managed to reconcile past with present, thus transforming once-troubled or troublesome issues, as in the case of Muslim presence within China, into a positive and reinvigorating force.Besides the obvious economic drive, there appears to have been a sincere desire to include and integrate this “foreign”element into the daily life of the new Republic of China 中華民國Zhōnghuá Mínguó, (1912-1949). Thus, particular attention will be given to the role played by Chinese women within these post-1912, “foreign”communities and, as for 澳門Macau, the post-1999 handover to China by the Portuguese on December 20, 1999.Though oftentimes considered as mere “consumers”and not “makers;”hence, allegedly not contributing to the overall “welfare”of the Country, Chinese women of “foreign”ethnicity who also happened to be Muslim, were eventually able to show the New Republicthat the 女工, nǚgōng—work done by women, in and outside the household—should instead be considered “productive”and, better yet, it should be seen as a positive sign within the new vision of Chinese nationalism where social class, race, ethnicity, language/dialect, religion, and gender all contributed to the welfare of the Country, or rather, the then-young Republic of China 中華民國,Zhōnghuá Mínguó. Finally, I will look at Muslim women of Uighur維吾爾, wéi wúĕr, and Huí回background who also contributed to this new vision

description: Objective: To determine if baseline biomarkers are associated with longitudinal changes in the worsening of disc space narrowing (DSN), vertebral osteophytes (OST), and low back pain (LBP). Design: Paired baseline (2003–2004) and follow-up (2006–2010) lumbar spine radiographs from the Johnston County Osteoarthritis Project were graded for severity of DSN and OST. LBP severity was self-reported. Concentrations of analytes (cytokines, proteoglycans, and neuropeptides) were quantified by immunoassay. Pressure-pain threshold (PPT), a marker of sensitivity to pressure pain, was measured with a standard dolorimeter. Binary logistic regression models were used to estimate odd ratios (OR) and 95% confidence intervals (CI) of biomarker levels with DSN, OST, or LBP. Interactions were tested between biomarker levels and the number of affected lumbar spine levels or LBP. Results: We included participants (n = 723) with biospecimens, PPT, and paired lumbar spine radiographic data. Baseline Lumican, a proteoglycan reflective of extracellular matrix changes, was associated with longitudinal changes in DSN worsening (OR = 3.19 [95% CI 1.22, 8.01]). Baseline brain-derived neuropathic factor, a neuropeptide, (OR = 1.80 [95% CI 1.03, 3.16]) was associated with longitudinal changes in OST worsening, which may reflect osteoclast genesis. Baseline hyaluronic acid (OR = 1.31 [95% CI 1.01, 1.71]), indicative of systemic inflammation, and PPT (OR = 1.56 [95% CI 1.02, 2.31]) were associated with longitudinal increases in LBP severity. Conclusion: These findings suggest that baseline biomarkers are associated with longitudinal changes occurring in structures of the lumbar spine (DSN vs OST). Markers of inflammation and perceived pressure pain sensitivity were associated with longitudinal worsening of LBP.

description: All measurements of cosmic star formation must assume an initial distribution of stellar masses -- the stellar initial mass function -- in order to extrapolate from the star-formation rate measured for typically rare, massive stars (> 8 Msun) to the total star-formation rate across the full stellar mass spectrum. The shape of the stellar initial mass function in various galaxy populations underpins our understanding of the formation and evolution of galaxies across cosmic time. Classical determinations of the stellar initial mass function in local galaxies are traditionally made at ultraviolet, optical and near-infrared wavelengths, which cannot be probed in dust-obscured galaxies, especially in distant starbursts, whose apparent star-formation rates are hundreds to thousands of times higher than in our Milky Way, selected at submillimetre (rest-frame far-infrared) wavelengths. The 13C/18O abundance ratio in the cold molecular gas -- which can be probed via the rotational transitions of the 13CO and C18O isotopologues -- is a very sensitive index of the stellar initial mass function, with its determination immune to the pernicious effects of dust. Here we report observations of 13CO and C18O emission for a sample of four dust-enshrouded starbursts at redshifts of approximately two to three, and find unambiguous evidence for a top-heavy stellar initial mass function in all of them. A low 13CO/C18O ratio for all our targets -- alongside a well-tested, detailed chemical evolution model benchmarked on the Milky Way -- implies that there are considerably more massive stars in starburst events than in ordinary star-forming spiral galaxies. This can bring these extraordinary starbursts closer to the `main sequence' of star-forming galaxies, though such main-sequence galaxies may not be immune to changes in initial stellar mass function, depending upon their star-formation densities.

description: Big Bang Nucleosynthesis represents perhaps the first, and still perhaps the most powerful particle-astrophysics connection. As such, it should provide an example for other work in this area. I discuss the current status of standard model BBN predictions and constraints, and then argue that the issue of observational systematic uncertainties is the key feature limiting our ability to constrain theory with observation. Nevertheless, several very important constraints are currently obtainable. For example, assuming maximal systematic uncertainties in $^4$He, D, and $^7$Li we find a conservative upper limit of $Ω_B \le 0.16$ in order for BBN predictions to agree with observations. Equally significant, we find that BBN predictions are inconsistent unless $^4He$ abundance by mass is greater than $23.9\%$, or D +$^3$He estimates are incorrect. By contrast, unless systematic uncertainties are taken into account, the quoted $2σ$ observational upper limit on the primordial $^4He$ fraction is $23.8\%$.

The Physics of Flash (Supernova) Spectroscopy

description: We examine flash spectroscopy of a circumstellar medium (CSM) ionized by the hard radiation pulse produced by the emerging shock of a supernova (SN). We first find that the rise and fall times of the Halpha emission constrains the location of the CSM with a peak at tpeak=Rstar sqrt(2/c vshock) for a star of radius Rstar and a shock velocity of vshock. The dropping temperature of the transient emission naturally reproduces the evolution of lines with different ionization energies. Second, for red supergiants (RSGs), the shock break out radiatively accelerates the CSM to produce broad, early-time line wings independent of the Thomson optical depth of the CSM. Finally, the CSM recombination rates in binaries can be dominated by a dense, cool, wind collision interface like those seen in Wolf-Rayet binaries rather than the individual stellar winds. Combining these three results, the flash spectroscopy observations of the normal Type IIP iPTF13dqy (SN 2013fs) are naturally explained by an RSG with a normal, Thomson optically thin wind in a binary with a separation of ~10^4 Rsun without any need for a pre-SN eruption. Similarly, the broad line wings seen for the Type IIb iPTF13ast (SN 2013cu), whose progenitors are generally yellow supergiants in binaries, are likely due to radiative acceleration of the CSM rather than pre-existing, Wolf-Rayet-like wind.

description: We propose to describe the acceleration of the universe by introducing a model of two coupled fluids. We focus on the accelerated expansion at the early stages. The inflationary expansion is described in terms of a van der Waals equation of state for the cosmic fluid, when account is taken of bulk viscosity. We assume that there is a weak interaction between the van der Waals fluid and the second component (matter). The gravitational equations for the energy densities of the two components are solved for a homogeneous and isotropic Friedmann-Robertson-Walker universe, and analytic expressions for the Hubble parameter are obtained. The slow-roll parameters, the spectral index, and the tensor-to-scalar ratio are calculated and compared with the most recent astronomical data from the Planck satellite. Given reasonable restriction on the parameters, the agreement with observations is favorable.

description: In this paper we describe a physical realization of a family of non-compact Kahler threefolds with trivial canonical bundle in hybrid Landau-Ginzburg models, motivated by some recent non-Kahler solutions of Strominger systems, and utilizing some recent ideas from GLSMs. We consider threefolds given as fiber products of compact genus g Riemann surfaces and noncompact threefolds. Each genus g Riemann surface is constructed using recent GLSM tricks, as a double cover of P^1 branched over a degree 2g + 2 locus, realized via nonperturbative effects rather than as the critical locus of a superpotential. We focus in particular on special cases corresponding to a set of Kahler twistor spaces of certain hyperKahler four-manifolds, specifically the twistor spaces of R^4, C^2/Z_k, and S^1 x R^3. We check in all cases that the condition for trivial canonical bundle arising physically matches the mathematical constraint.

Realizing that major proposals toward the knee's shape can be divided into two categories: the rigidity-dependent (also Z-dependent) knee and the mass-dependent (also A-dependent) knee, where the former one relates to the acceleration or the propagation mechanisms, and the other one is often associated with the new physics, it is essential to precisely measure the individual compositions. Benefit from the high altitude and hybrid detection methods, the LHAASO experiment has the ability in determining the individual component and brings us an opportunity in discriminating these two models. We test this expected ability of LHAASO from 100 TeV to 10 PeV with 3-year observation. And find the dominant component at the knee is essential to this issue, while much heavier nuclei occupying the knee leads to higher significance. In the analysis, the He-dominant knee under the A-dependent case can be recognized at the significance about 6.6 $σ$, while the P-dominant knee under the Z-dependent case will be classified with 2 $σ$ significance.

description: A globalização assume um papel determinante no desenvolvimento das relações internacionais e na transformação das relações económicas, sociais e culturais entre o Estado e a sociedade civil. Vivemos uma época marcada pela mobilidade global de uma série de fatores irregulares, imprevisíveis e heterogéneos relativamente aos quais é necessário criar regras comuns de governação. Este fenómeno levanta uma série de questões aos cidadãos e obriga a uma resposta que tenha em conta a natureza das atividades humanas e as dimensões nacionais, regionais e mesmo internacionais nas quais os cidadãos operam.

description: The recently-discovered, nearby young supernova remnant in the southeast corner of the older Vela supernova remnant may have been seen in measurements of nitrate abundances in Antarctic ice cores. Such an interpretation of this twenty-year-old ice-core data would provide a more accurate dating of this supernova than is possible purely using astrophysical techniques. It permits an inference of the supernova4s ${}^{44}$Ti yield purely on an observational basis, without reference to supernova modelling. The resulting estimates of the supernova distance and light-arrival time are 200 pc and 700 years ago, implying an expansion speed of 5,000 km/s for the supernova remnant. Such an expansion speed has been argued elsewhere to imply the explosion to have been a 15 $M_\odot$ Type II supernova. This interpretation also adds new evidence to the debate as to whether nearby supernovae can measurably affect nitrate abundances in polar ice cores.

description: We consider standing lattice solitons for discrete nonlinear Schrodinger equation with saturation (NLSS), where so-called transparent points were recently discovered. These transparent points are the values of the governing parameter (e.g., the lattice spacing) for which the Peierls-Nabarro barrier vanishes. In order to explain the existence of transparent points, we study a solitary wave solution in the continuous NLSS and analyse the singularities of its analytic continuation in the complex plane. The existence of a quadruplet of logarithmic singularities nearest to the real axis is proven and applied to two settings: (i) the fourth-order differential equation arising as the next-order continuum approximation of the discrete NLSS and (ii) the advance-delay version of the discrete NLSS.

Penguin Enhancement and $B\to Kπ$ decays in perturbative QCD

description: We compute branching ratios of $B\to Kπ$ decays in the framework of perturbative QCD factorization theorem. Decay amplitudes are classified into the topologies of tree, penguin and annihilation, all of which contain both factorizable and nonfactorizable contributions. These contributions are expressed as the convolutions of hard $b$ quark decay amplitudes with universal meson wave functions. It is shown that (1) matrix elements of penguin operators are dynamically enhanced compared to those employed in the factorization assumption; (2) annihilation diagrams are not negligible, contrary to common belief; (3) annihilation diagrams contribute large strong phases; (4) the uncertainty of current data of the ratio $R={\cal B}(B_d^0\to K^\pmπ^\mp)/{\cal B}(B^\pm\to K^0π^\pm)$ and of CP asymmetries is too large to give a constraint of $ϕ_3$. Assuming $ϕ_3=90^o$ which is extracted from the best fit to the data of $R$, predictions for the branching ratios of the four $B\to Kπ$ modes are consistent with data.

Is Physics in the Infinite Momentum Frame Independent of the Compactification Radius?

description: With the aim of clarifying the eleven dimensional content of Matrix theory, we examine the dependence of a theory in the infinite momentum frame (IMF) on the (purely spatial) longitudinal compactification radius R. It is shown that in a point particle theory the generic scattering amplitude becomes independent of R in the IMF. Processes with zero longitudinal momentum transfer are found to be exceptional. The same question is addressed in a theory with extended objects. A one-loop type II string amplitude is shown to be R-independent in the IMF, and to coincide with that of the uncompactified theory. No exceptional processes exist in this case. The possible implications of these results for M-theory are discussed. In particular, if amplitudes in M-theory are independent of R in the IMF, Matrix theory can be rightfully expected (in the N -> infty limit) to describe uncompactified M-theory.

description: Canción de Tumba, de Julián Herbert, foi traduzida para o português como Cantiga de Findar. Na narrativa, a mãe do narrador tem leucemia e agoniza no hospital. Ao refletir sobre a condição de sua mãe e a a sua própria, o narrador vai contar também a história de sua pátria, o México. Este trabalho tem por objetivo traçar uma relação entre esses elementos. Como é uma narrativa autoficcional, não há clareza na distinção entre ficção e história, mas o paralelo entre essas duas é presente na história de sua mãe e de sua pátria. Como pano de fundo da discussão, usaremos o texto Mother, Nation, and Self: Poetics of Death and Subjectivity in Julián Herbert’s Canción de Tumba, de Raúl C. Verduzo, em que o autor trata da relação entre mãe, pátria e nação.

Coherence of neutrino flavor mixing in quantum field theory

Publisher: name: arXiv
Year: 1999
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: In the simplistic quantum mechanical picture of flavor mixing, conditions on the maximum size and minimum coherence time of the source and detector regions for the observation of interference---as well as the very viability of the approach---can only be argued in an ad hoc way from principles external to the formalism itself. To examine these conditions in a more fundamental way, the quantum field theoretical $S$-matrix approach is employed in this paper, without the unrealistic assumption of microscopic stationarity. The fully normalized, time-dependent neutrino flavor mixing event rates presented here automatically reveal the coherence conditions in a natural, self-contained, and physically unambiguous way, while quantitatively describing the transition to their failure.

description: Zinc (Zn) is an imperative micro-nutrient for plant growth and development. Zinc is deficient all over the world, particularly in the developing countries and Zn sulfate is supplied as a source of Zn fertilizer. However, maximum part of the applied Zn sulfate become fixed in the soil and unavailable to plant. Plant growth promoting bacteria improving the crop growth and yield on sustainable basis. Inoculation of bacterial strains used is an effective technology, but limited research is available under field conditions. Therefore, field experiment was conducted under irrigated and rainfed conditions to evaluate the inoculation effect of indigenous beneficial microbes (BM) on wheat growth, yield and Zn accumulation. Different treatment combinations (0, 4, 8, 12, 16, and 20 kg Zn ha−1 without and with BM) were used on two wheat varieties (Wadaan-17 and Zincol-16). Results revealed that inoculating BM with chemical Zn fertilizer significantly (P ≤ .05) boosted yield and Zn accumulation in grain and straw. In irrigated conditions, yield increased by 33%, Zn accumulation in grain by 141% and in straw by 98.2%, but in rainfed conditions, yield increased by 38.9% Zn accumulation in grain by 130% and in straw by 123%. Compared to Zincol-16, Wadaan-17 performed better in terms of yield and Zn accumulation under both irrigated and rainfed conditions. The study concluded that inoculation of certain BM might reduce the rate at which chemical Zn fertilizer was used in both irrigated and rainfed conditions and could be employed as potential bio-inoculants.

description: We investigate the formation of circumnuclear gas structures from the tidal disruption of molecular clouds in galactic nuclei, by means of smoothed particle hydrodynamics simulations. We model galactic nuclei as composed of a supermassive black hole (SMBH) and a nuclear star cluster (NSC) and consider different mass ratios between the two components. We find that the relative masses of the SMBH and the NSC have a deep impact on the morphology of the circumnuclear gas. Extended disks form only inside the sphere of influence of the SMBH. In contrast, compact rings naturally form outside the SMBH's sphere of influence, where the gravity is dominated by the NSC. This result is in agreement with the properties of the Milky Way's circumnuclear ring, which orbits outside the SMBH sphere of influence. Our results indicate that compact circumnuclear rings can naturally form outside the SMBH sphere of influence.
