description: We present a consistent fusion of functional renormalization group and mean-field theory which explicitly introduces a bosonic field via a Hubbard-Stratonovich transformation at the critical scale, at which the order sets in. We show that a minimal truncation of the flow equations, that neglects order parameter fluctuations, is integrable and fulfills fundamental constraints as the Goldstone theorem and the Ward identity connected with the broken global symmetry. To introduce the bosonic field, we present a technique to factorize the most singular part of the vertex, even when the full dependence on all its arguments is retained. We test our method on the two-dimensional attractive Hubbard model at half-filling and calculate the superfluid gap as well as the Yukawa couplings and residual two fermion interactions in the ordered phase as functions of fermionic Matsubara frequencies. Furthermore, we analyze the gap and the condensate fraction for weak and moderate couplings and compare our results with previous functional renormalization group studies, and with quantum Monte Carlo data. Our formalism constitutes a convenient starting point for the inclusion of order parameter fluctuations by keeping a full, non simplified, dependence on fermionic momenta and/or frequencies.

description: A multiple-tip ultra-high vacuum (UHV) scanning tunneling microscope (MT-STM) with a scanning electron microscope (SEM) for imaging and molecular-beam epitaxy growth capabilities has been developed. This instrument (nanoworkbench) is used to perform four-point probe conductivity measurements at micrometer spatial dimension. The system is composed of four chambers, the multiple-tip STM/SEM chamber, a surface analysis and preparation chamber, a molecular-beam epitaxy chamber and a load-lock chamber for fast transfer of samples and probes. The four chambers are interconnected by a unique transfer system based on a sample box with integrated heating and temperature-measuring capabilities. We demonstrate the operation and the performance of the nanoworkbench with STM imaging on graphite and with four-point-probe conductivity measurements on a silicon-on-insulator (SOI) crystal. The creation of a local FET, whose dimension and localization are respectively determined by the spacing between the probes and their position on the SOI surface, is demonstrated.

FibeR-CNN: Expanding Mask R-CNN to Improve Image-Based Fiber Analysis
Creators: name: Frei, Max

Publisher: name: arXiv

Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)
subject: FOS: Computer and information sciences

description: Fiber-shaped materials (e.g. carbon nano tubes) are of great relevance, due to their unique properties but also the health risk they can impose. Unfortunately, image-based analysis of fibers still involves manual annotation, which is a time-consuming and costly process. We therefore propose the use of region-based convolutional neural networks (R-CNNs) to automate this task. Mask R-CNN, the most widely used R-CNN for semantic segmentation tasks, is prone to errors when it comes to the analysis of fiber-shaped objects. Hence, a new architecture - FibeR-CNN - is introduced and validated. FibeR-CNN combines two established R-CNN architectures (Mask and Keypoint R-CNN) and adds additional network heads for the prediction of fiber widths and lengths. As a result, FibeR-CNN is able to surpass the mean average precision of Mask R-CNN by 33 % (11 percentage points) on a novel test data set of fiber images.

description: L’adoption des modèles internes de mesure du risque de marché a été une étape majeure dans la régulation financière marocaine, la diversité des méthodes de gestion de risque qui existent et la spécificité de chacune d’entre elles impliquent une vigilance particulière dans son application en fonction de la nature du marché boursier concerné. En effet, la connaissance du lien de causalité existant entre indices bousiers devient essentiel pour la mise en place des politiques adaptées. L’objectif de cet article est de montrer que les modèles VAR classiques peuvent être utilisés avec la régression Gini (VAR-Gini) afin d’étudier la relation de causalité pouvant exister entre MASI, le CAC40 et le SP500. En présence de valeurs aberrantes le recours à la régression de Gini permet d’obtenir des estimateurs plus robustes à l’aide des modèles VAR. En effet, nous avons déterminé la causalité classique et celle de Granger au sens Gini. Au regard des relations que le Maroc entretient avec ses deux principaux partenaires commerciaux français et américain, l’étude de la causalité a prouvé que l’évolution de l’indice boursier MASI dépend étroitement des indices boursiers SP500 et CAC40.

description: We present an ``algebraic treatment'' of the analytical Bethe ansatz for open spin chains with soliton non preserving (SNP) boundary conditions. For this purpose, we introduce abstract monodromy and transfer matrices which provide an algebraic framework for the analytical Bethe ansatz. It allows us to deal with a generic gl(N) open SNP spin chain possessing on each site an arbitrary representation. As a result, we obtain the Bethe equations in their full generality. The classification of finite dimensional irreducible representations for the twisted Yangians are directly linked to the calculation of the transfer matrix eigenvalues.

description: This paper argues that within the range of complementary activities necessary to secure the food security of marginalised groups in South Africa in places such as Greater Sekhukhune, the aspect of agricultural production is often neglected. A comprehensive approach to food security should focus on exploiting opportunities around increasing local food availability through production, as well as stimulating food accessibility by, for example, supporting small enterprises through micro-credit, and supporting food utilisation through education. In this way a range of options is created that vulnerable people can adopt to promote their livelihoods beyond survivalist strategies. This paper explores the issue of agricultural production within Greater Sekhukhune to provide insights into the challenges facing a comprehensive food security strategy that would guarantee food supply through a range of interventions. The study in the Greater Sekhukhune District in Limpopo Province was conducted through two sets of household surveys (2004 and 2006) and the responses to the agricultural production part of these surveys are discussed. Marked changes from 2004 to 2006 were observed. For “agrarian reform” to be a success, the necessary institutional framework needs to be in place to enable a broad range of services from government and non-governmental actors. The facilitation of such “joined up government”, although in existence in theory, requires concerted political will to become a reality.
Lunin-Maldacena Deformations With Three Parameters

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We examine the solution generating symmetries by which Lunin and Maldacena have generated the gravity duals of beta-deformations of certain field theories. We identify the O(2,2,R) matrix, which acts on the background matrix E=g+B, where g and B are the metric and the B-field of the undeformed background, respectively. This simplifies the calculations and makes some features of the deformed backgrounds more transparent. We also find a new three-parameter deformation of the Sasaki-Einstein manifolds T^{1,1} and Y^{p,q}. Following the recent literature on the three-parameter deformation of AdS_5 \times S^5, one would expect that our new solutions should correspond to non-supersymmetric marginal deformations of the relevant dual field theories.

Difference in B^+ and B^0 Direct CP Asymmetry as Effect of a Fourth Generation

description: Direct CP violation in B^0-> K^+π^- decay has emerged at -10% level, but the asymmetry in B^+ -> K^+π^0 mode is consistent with zero. This difference points towards possible New Physics in the electroweak penguin operator. We point out that a sequential fourth generation, with sizable V^*_{t's}V_{t'b} and near maximal phase, could be a natural cause. We use the perturbative QCD factorization approach for B-> Kπamplitudes. While the B^0-> K^+π^- mode is insensitive to t', we critically compare t' effects on direct CP violation in B^+ -> K^+π^0 with b-> s\ell^+\ell^- and B_s mixing. If the K^+π^0-K^+π^- asymmetry difference persists, we predict \sin2Φ_{B_s} to be negative.

description: We study the modelling of the Halo Occupation Distribution (HOD) for the eBOSS DR16 Emission Line Galaxies (ELGs). Motivated by previous theoretical and observational studies, we consider different physical effects that can change how ELGs populate haloes. We explore the shape of the average HOD, the fraction of satellite galaxies, their probability distribution function (PDF), and their density and velocity profiles. Our baseline HOD shape was fitted to a semi-analytical model of galaxy formation and evolution, with a decaying occupation of central ELGs at high halo masses. We consider Poisson and sub/super-Poissonian PDFs for satellite assignment. We model both NFW and particle profiles for satellite positions, also allowing for decreased concentrations. We model velocities with the virial theorem and particle velocity distributions. Additionally, we introduce a velocity bias and a net infall velocity. We study how these choices impact the clustering statistics while keeping the number density and bias fixed to that from eBOSS ELGs. The projected correlation function, $w_p$, captures most of the effects from the PDF and satellites profile. The quadrupole, $ξ_2$, captures most of the effects coming from the velocity profile. We find that the impact of the mean HOD shape is subdominant relative to the rest of choices. We fit the clustering of the eBOSS DR16 ELG data under different combinations of the above assumptions. The catalogues presented here have been analysed in companion papers, showing that eBOSS RSD+BAO measurements are insensitive to the details of galaxy physics considered here. These catalogues are made publicly available.

In view of this, the objective of this paper was to develop a decision support tool based in system dynamics to be appled to this activity. To perform the simulations with the model they were used data from a representative milk production farm of the state of Minas Gerais, Brazil. The results obtained with simulations showed coherence with settled previously analysis. The system dynamics showed also to be very helpful to get a better understanding of milk production systems and to perform strategic planning.
Dynamical mean field theory for strongly correlated inhomogeneous multilayered nanostructures

description: Dynamical mean field theory is employed to calculate the properties of multilayered inhomogeneous devices composed of semi-infinite metallic lead layers coupled via barrier planes that are made from a strongly correlated material (and can be tuned through the metal-insulator Mott transition). We find that the Friedel oscillations in the metallic leads are immediately frozen in and don't change as the thickness of the barrier increases from one to eighty planes. We also identify a generalization of the Thouless energy that describes the crossover from tunneling to incoherent Ohmic transport in the insulating barrier. We qualitatively compare the results of these self-consistent many-body calculations with the assumptions of non-self-consistent Landauer-based approaches to shed light on when such approaches are likely to yield good results for the transport.

description: Many proposals in exploring topological quantum computation are based on superconducting quantum devices constructed on materials with strong spin-orbit coupling (SOC). For these devices, a full control on both the magnitude and the spatial distribution of the supercurrent would be highly demanded, but has been elusive up to now. We constructed proximity-type Josephson junction on nanoplates of Bi2O2Se, a new emerging semiconductor with strong SOC. Through electrical gating, we show that the supercurrent can be fully turned ON and OFF, and its real-space pathways can be configured either through the bulk or along the edges. Our work demonstrates Bi2O2Se as a promising platform for constructing multifunctional hybrid superconducting devices as well as for searching for topological superconductivity.

description: We examine connection matrices of Ising systems with long-rang interaction on d-dimensional hypercube lattices of linear dimensions L. We express the eigenvectors of these matrices as the Kronecker products of the eigenvectors for the one-dimensional Ising system. The eigenvalues of the connection matrices are polynomials of the d-th degree of the eigenvalues for the one-dimensional system. We show that including of the long-range interaction does not remove the degeneracy of the eigenvalues of the connection matrix. We analyze the eigenvalue spectral density in the limit L go to \infty. In the case of the continuous spectrum, for d < 3 we obtain analytical formulas that describe the influence of the long-range interaction on the spectral density and the crucial changes of the spectrum.

Performance of the CMS Level-1 trigger in proton-proton collisions at $\sqrt{s} =$ 13 TeV

description: At the start of Run 2 in 2015, the LHC delivered proton-proton collisions at a center-of-mass energy of 13 TeV. During Run 2 (years 2015-2018) the LHC eventually reached a luminosity of 2.1 $\times$ 10$^{34}$ cm$^{-2}$ s$^{-1}$, almost three times that reached during Run 1 (2009-2013) and a factor of two larger than the LHC design value, leading to events with up to a mean of about 50 simultaneous inelastic proton-proton collisions per bunch crossing (pileup). The CMS Level-1 trigger was upgraded prior to 2016 to improve the selection of physics events in the challenging conditions posed by the second run of the LHC. This paper describes the performance of the CMS Level-1 trigger upgrade during the data taking period of 2016-2018. The upgraded trigger implements pattern recognition and boosted decision tree regression techniques for muon reconstruction, includes pileup subtraction for jets and energy sums, and incorporates pileup-dependent isolation requirements for electrons and tau leptons. In addition, the new trigger calculates high-level quantities such as the invariant mass of pairs of reconstructed particles. The upgrade reduces the trigger rate from background processes and improves the trigger efficiency for a wide variety of physics signals.

Two diffraction cones of elastic scattering and structural symmetry conjecture
Creators: name: Samokhin, A. P.
Publisher: name: arXiv
Year: 2020
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The energy dependence of the differential cross-section of elastic proton-proton scattering in the ISR--LHC energy range is discussed for fixed values of momentum transfer in the region of the forward diffraction cone, in the region beyond the second maximum of $dσ/dt$ and in the vicinity of the dip-bump structure. As can be seen from the currently available experimental data, the differential cross-section in the region beyond the second maximum has exactly the same properties as in the forward diffraction cone, including the existence of a stationary point, that is, we observe a second diffraction cone, which has the same origin as the forward peak. The simplest natural explanation for this experimental fact is that the amplitude of high energy elastic scattering is the sum of two similar terms that have the same status and differ only in the values of parameters. The energy dependence of $dσ/dt$ for a fixed $t$ in the region of the dip-bump structure, where these two terms interfere, confirms the above observations. We discuss the possible origin of the two-component structure of the high energy elastic scattering amplitude and explain this by the structural symmetry of the amplitude.

description: Suppose that the production, y = f (x1, x2,..., xs ) , is known. It says that we are able to know for each value of the input vector, 1 2 , ,..., s x x x , the correspondent value of y. Or yet production growth occurs as consequence of movement along the production frontier, and it requires a different combination of inputs, and consequently, a higher or a smaller expenditure. Another representation of the production structure is, 1 2 ( , ,..., , ) s y = f x x x t , where t is non negative real number. Now each set of 1 2 , ,..., s x x x gives a different y as t varies. Or, it is possible to achieve a higher level of production with no additional cost. A question comes to mind: can the real world (or the data) say which one of the two representations has a better descriptive power? The answer is no. Or yet, the real world cannot distinguish between embodied and disembodied technology in a sense that will be introduced below. We will not use directly the concept of production function to establish the model appropriate to test embodied technology against the disembodied one. In its place, the rates of growth of products and inputs are instrumental.

description: Purpose: To propose a self-supervised deep learning-based compressed sensing MRI (DL-based CS-MRI) method named "Adaptive Self-Supervised Consistency Guided Diffusion Model (ASSCGD)" to accelerate data acquisition without requiring fully sampled datasets. Materials and Methods: We used the fastMRI multi-coil brain axial T2-weighted (T2-w) dataset from 1,376 cases and single-coil brain quantitative magnetization prepared 2 rapid acquisition gradient echoes (MP2RAGE) T1 maps from 318 cases to train and test our model. Robustness against domain shift was evaluated using two out-of-distribution (OOD) datasets: multi-coil brain axial postcontrast T1 -weighted (T1c) dataset from 50 cases and axial T1-weighted (T1-w) dataset from 50 patients. Data were retrospectively subsampled at acceleration rates R in {2x, 4x, 8x}. ASSCGD partitions a random sampling pattern into two disjoint sets, ensuring data consistency during training. We compared our method with ReconFormer Transformer and SS-MRI, assessing performance using normalized mean squared error (NMSE), peak signal-to-noise ratio (PSNR), and structural similarity index (SSIM). Statistical tests included one-way analysis of variance (ANOVA) and multi-comparison Tukey's Honesty Significant Difference (HSD) tests. Results: ASSCGD preserved fine structures and brain abnormalities visually better than comparative methods at R = 8x for both multi-coil and single-coil datasets. It achieved the lowest NMSE at R in {4x, 8x}, and the highest PSNR and SSIM values at all acceleration rates for the multi-coil dataset. Similar trends were observed for the single-coil dataset, though SSIM values were comparable to ReconFormer at R in {2x, 8x}. These results were further confirmed by the voxel-wise correlation scatter plots. OOD results showed significant (p << 10^-5 ) improvements in undersampled image quality after reconstruction.

description: Campaigns to prevent the spread of HIV require accurate knowledge of the characteristics of those most likely to contract the disease. Studies conducted in Sub-Saharan Africa during the 1980s generally found a positive correlation between socioeconomic characteristics such as education, income, and wealth and subsequent contraction of HIV. As the disease has progressed, the relationship between socioeconomic status and HIV contraction may have changed, although there is little evidence to support this. An emerging strand of the literature on the AIDS epidemic in Africa posits that poverty is increasingly associated with the spread of the disease. However, this conclusion is somewhat contentious, as other recent studies find mixed evidence of a poverty-AIDS connection. This study attempts to shed light on these issues by reporting findings from two linked studies on the socioeconomic characteristics of prime-age individuals (defined as ages 15 to 59) dying of disease-related causes in Zambia and Kenya.

description: This study has the objective of evaluating the economic effects of the Brazilian integration into the Free Trade Association of Americas - FTAA under two alternative scenarios. In the first, the adhesion of the Brazilian economy would happen as an isolated country. In the second, the joint adhesion of Brazil would follow the rules established for all members of MERCOSUR. The analytical framework is that of an applied general equilibrium analysis which permit the measurement of different impacts of simulations on selected economic indicators. The results point out that the joint adhesion of MERCOSUR countries as an economic block into FTAA, which is the position defended by Brazilian negotiators, is much more beneficial to the Brazilian economy than the integration as an independent country. The impacts of integration in FTAA on the growth of disposable income, taxation, and personal consumption are much higher under the second scenario. Therefore, this study supports the Brazilian posture that the FTAA should not be negotiated with isolated countries but taking into account all the previous agreements prevailing in South America.

description: The paper develops the concept of return to scale at an elementary level, but rigorously. It is argued that constant and increasing returns are incompatible with competitive markets, because they imply the convergence to few firms, and this is not the case for the real world. The main point is that average cost curve has the shape of a U, and, without restrictions, the firms converge to the branch of decreasing returns. If on the real world is detected increasing or constant returns, it suggests that it should be looked for the market imperfection that are the base of them. And results of increasing or constant returns of econometric models must be taken as a sign of market imperfections. Yet the knowledge of the market imperfections is crucial to design economic policies for economic development with equal opportunities for all. The pattern of six crops showed that the supply is largely in the hands of few farmers, and the great majority of them contribute with a small share of the production. This pattern is clearer for modern crops, as it is the case of soybeans. The results of an econometric model for two groups of small farmers-one with nonnegative profit and the other with negative profit, pointed out increasing returns for the poorer group, and that it was not able to expand production to the cost curve branch of decreasing returns in consequence of market failures.

description: We derive the canonical structure and hamiltonian for arbitrary deformations of a higher-dimensional (quantum Hall) droplet of fermions with spin or color on a general phase space manifold. Gauge fields are introduced via a Kaluza-Klein construction on the phase space. The emerging theory is a nonlinear higher-dimensional generalization of the gauged Kac-Moody algebra. To leading order in h-bar this reproduces the edge state chiral Wess-Zumino-Witten action of the droplet.

description: We discuss theoretically a frustrated Heisenberg antiferromagnet in magnetic field close to the saturation one. It is demonstrated that a small biaxial anisotropy and/or the magnetic dipolar interaction produce a delicate balance between phases with a commensurate canted, incommensurate helical (conical), and fan spin orderings. As a result, different sequences of phase transitions are realized depending on values of these small anisotropic interactions. We derive analytical expressions for critical fields and ground-state energies of the phases which are in a quantitative agreement with our and previous Monte-Carlo simulations.

description: bJetsInt.txt
description: CERN-LHC. Measurement of the jet shapes in top-quark pair events from proton-proton collisions at a centre-of-mass energy of 7 TeV. The analysis uses a data sample of integrated luminosity 1.8 fb-1. Jets are reconstructed using the anti-kT algorithm with jet radius R=0.4. Jet shapes are presented as differential and integrated defined as: Differential (RHO) - scalar sum of jet PT in an annulus of thickness deltaR around radius r / scalar sum of jet PT in the cone of radius R. Integrated (PSI) - scalar sum of jet PT in cone radius r / scalar sum of jet PT in cone radius R. Data are shown separated into b-jets and light-jet events. UPDATE (22 JUL 2014): Information on the different sources of systematic uncertainty is given in the following four links, containing tables with the relative values of the uncertainty (in %) for both the differential (Diff) and integrated (Int) versions of the jet shapes for both light- (lJets) and b-jets (bJets). The uncertainties indicated with (Up) and (Down) are asymmetric, while the rest are symmetric on each bin.

Fulde-Ferrell states in unequally charged Fermi gases

description: Atoms with different internal states can exhibit different responses to an artificial magnetic field. An atomic gas mixture of two different components can therefore be interpreted as a mixture of two atomic gases carrying different synthetic charges. We consider the superfluid state of such unequally charged Fermi gases coupled to a magnetic field via the orbital effect and trapped in a torus geometry. The orbital coupling to the magnetic field favors an inhomogeneous superfluid state with optimum finite center-of-mass momentum pairing. The resulting population-balanced orbital Fulde-Ferrell (FF) state is robust against the magnetic field and does not undergo pair breaking unlike the conventional BCS and Fulde-Ferrell-Larkin-Ovchinnikov type pairing states under the Zeeman effect. We contrast the homogeneous and inhomogeneous cases emphasizing the advantages of the unequally charged systems and present their momentum distributions. We conclude that an unequally charged atomic Fermi gas system orbitally coupled to an artificial magnetic field provides an ideal candidate for experimental realization of the FF state.

description: The objective of this work is to determine factors that explain the alteration of the participation of the Brazilian soybean agro-industry and industry in the international trade. Particularly, it intends to analyze the Brazilian competitiveness in the exports of each segment of the soybean agro-industry. For this, the Constant-Market-Share (CMS) model was used, through which, the discrepancies were computed in the potential and effectual variation of the Brazilian exports of soybeans, soybean meal and oil, disaggregating them in these components: market size, market distribution and competitiveness. The market size was shown positive for the three analyzed segments, demonstrating that the expansion of the world demand of soybean and its by-products it was fundamental factor to the growth of the Brazilian exports. The effect market distribution was negative, indicating that there are inefficiencies in the commercialization channels of the Brazilian of soybean agro-industry. The competitiveness, for its time, was only positive for the soy exports in grain. However, it stands out that the positive impact of the competitiveness, in the soy segment in grain compensated more in monetary values than the negative impacts in the soybean meal and oil segments. In that way, are necessary government politics that improve the infrastructure and, consequently, reduce the costs for improvement of the competitiveness in the soybean meal and oil segments.

description: Genetic diversity is the foundation for introducing plant development programs. Scientists and breeders used various methods, ranging from modern crossing to classical biotechnologies, to address the restricted incidence of natural mutations. Incomplete gene disruption or spontaneous injection of transgenes into plant genomes also occurs in earlier generations of knockout and gainoffunction technologies. Recent advances in genetic engineering has brought numerous benefits to the food and agriculture sector by improving the essential features of agricultural features. The CRISPR / Cas9 technology emerges from a bacterial immune system of type II and represents a new age of selective genome editing technology that can be spread to almost all species. In this paper, we have focused on advancements in the utilization of the CRISPR-Cas9 system in the food and agricultural industry, particularly in the development of resistant crops with improved quality and productivity
