description: In the conventional metric formulation of gravity, the Higgs Inflation model violates unitarity in the electroweak vacuum in Higgs scattering at the energy scale $Λ\sim M_{Pl}/ξ$, where $ξ\sim 10^4$ is the non-minimal coupling of the Higgs to the Ricci scalar. In the Palatini formulation it is commonly believed that $Λ\sim M_{Pl}/\sqrtξ$, where $ξ\sim 10^{9}$. Here we reconsider unitarity violation in the electroweak vacuum in the Palatini formulation. We argue that there is no unitarity violation in Higgs scattering in the Palatini non-minimally coupled Standard Model in the electroweak vacuum at energies below the Planck scale. In this case Palatini Higgs Inflation completely conserves unitarity and is consistent at all energies up to those at which quantum gravity becomes important. If true, this would imply that Palatini Higgs Inflation has a significant advantage over metric Higgs Inflation.

description: Several enigmatic questions have come up on the formation and chemical evolution of the Milky Way over the last decade. The detailed chemical abundances of the old, long-lived, metal-poor halo stars provide insights into the nature of the early chemical enrichment events leading to the formation of the metals in the universe. In this talk, I will present a study on the detailed chemical abundances of very faint and extremely metal-poor stars from the R-process Alliance using the GTC. Here, we discuss the detailed abundances of light, alpha, Fe-peak and r-process elements of the faintest RPA sample of stars. The over-abundance of carbon for the most metal-poor stars indicates mixing and fallback type of supernova as the primary progenitor. We use the alpha elements to demonstrate that massive stars were the most likely progenitors at the lowest metallicities. We also identify stars of globular cluster origin at very low metallicities using the light element anticorrelation, which suggests further lowering the metallicity floor of GCs and revisiting the Galactic chemical evolutionary models. The neutron capture elements (Sr, Ba and Eu) could be measured, and several new R-process Enhanced stars have been identified for follow-up studies. We have also used the astrometric parameters from Gaia to obtain the kinematics of all the stars to understand the nature of their origin in the Galaxy. Thus we derive the complete chemodynamical history of the stellar population in this study.

description: Nanoisland gold films, deposited by vacuum evaporation of gold onto Si(100) substrates, were irradiated with 1.5 MeV Au$^{2+}$ ions up to a fluence of $5\times 10^{14}$ ions cm$^{-2}$ and at incidence angles up to $60^{\circ}$ with respect to the surface normal. The sputtered particles were collected on carbon coated grids (catcher grid) during ion irradiation and were analyzed with transmission electron microscopy and Rutherford backscattering spectrometry. The average sputtered particle size and the areal coverage are determined from transmission electron microscopy measurements, whereas the amount of gold on the substrate is found by Rutherford backscattering spectrometry. The size distributions of larger particles (number of atoms/particle, $n$ $\ge$ 1,000) show an inverse power-law with an exponent of $\sim$ -1 in broad agreement with a molecular dynamics simulation of ion impact on cluster targets.

description: Instituições de saúde, como a Organização Mundial da Saúde (OMS), incluem algumas ferramentas de redes sociais (como Facebook, Twitter e outras) como parte crucial na divulgação de informações confiáveis sobre saúde, monitoramento de crises de saúde e contenção de boatos online. No Brasil, para combater a disseminação de notícias falsas, o Ministério da Saúde lançou um programa para verificar veracidade de mensagens online. No entanto, a complexidade de lidar com a comunicação durante uma crise de saúde é bastante alta, pois as mídias sociais, em comparação com as mídias tradicionais, são mais difíceis de monitorar, rastrear e analisar. Diante desse contexto, este trabalho apresenta uma análise sentimental a partir de um conjunto de dados composto por 1.285 rumores e não rumores em português do Brasil identificados por jornalistas e pelo Ministério da Saúde do Brasil.
Dynamical hysteresis properties of the driven-dissipative Bose-Hubbard model with a Gutzwiller Monte Carlo approach

description: We study the dynamical properties of a driven-dissipative Bose-Hubbard model in the strongly interacting regime through a quantum trajectory approach with a cluster-Gutzwiller Ansatz for the wave function. This allows us to take classical and quantum correlations into account. By studying the dynamical hysteresis surface that arises by sweeping through the coherent driving strength we show that the phase diagram for this system is in qualitative correspondence with the Gutzwiller mean-field result. However, quantitative differences are present and the inclusion of classical and quantum correlations causes a significant shift of the critical parameters. Additionally, we show that approximation techniques relying on a unimodal distribution such as the mean field and $1/z$ expansion drastically underestimate the particle number fluctuations. Finally, we show that a proposed mapping of the driven-dissipative many-body Bose-Hubbard model onto a single driven-dissipative Kerr model is not accurate for parameters in the hysteresis regime.

description: Studies of the long-range interactions between cold atoms and surfaces are now of vital interest. The interest is partly driven by nanotechnology applications, partly by the exploding interest in the encompassing superfield of Casimir effects, and partly by the burgeoning overlap between atomic and molecular physics, condensed matter, and quantum optics. This tutorial lecture will address long-range atom-surface interactions for cold atoms, including an overview of Casimir-Polder interactions and their various manifestations. Some previous theoretical studies that are of particular relevance will be reviewed. In addition some different approaches to the problem and corresponding results, especially concerning the effects of substrate composition, geometry, and finite temperature, will be discussed.

description: Gravitational wave (GW) detections of binary black holes (BBHs) have shown evidence for a dearth of component black holes with masses above $\sim50M_\odot$. This is consistent with expectations of a mass gap due to the existence of pair-instability supernovae (PISN). We argue that ground-based GW detectors will be sensitive to BBHs with masses above this gap, $\gtrsim120\,M_\odot$. With no detections, two years at upgraded sensitivity (A+) would constrain the local merger rate of these BBHs on the "far side" of the PISN gap to be lower than $0.01\,\mathrm{yr}^{-1}\mathrm{Gpc}^{-3}$. Alternatively, with a few tens of events we could constrain the location of the upper edge of the gap to the percent level. We consider the potential impact of "interloper" black holes within the PISN mass gap on this measurement. Far side BBHs would also be observed by future instruments such as Cosmic Explorer (CE), Einstein Telescope (ET) and LISA, and may dominate the fraction of multi-band events. We show that by comparing observations from ground and space it is possible to constrain the merger rate history. Moreover, we find that the upper edge of the PISN mass gap leaves an imprint on the spectral shape of the stochastic background of unresolved binaries, which may be accessible with A+ sensitivity. Finally, we show that by exploiting the upper edge of the gap, these high-mass BBHs can be used as standard sirens to constrain the cosmic expansion at redshifts of $\sim0.4$, $0.8$, and~$1.5$ with LISA, LIGO-Virgo, and CE/ET, respectively. These far-side binaries would be the most massive BBHs LIGO-Virgo could detect.

description: Web-based applications have become one of the most popular platforms in the world where users can easily access any application. This means a large number of users are connected from a network, transacting sensitive data and valuable information constantly. Therefore, ensuring these data security has become a challenging path for software tests professionals; there are a lot of technical and behavior implications and security of browser-based applications as compared to conventional client-based architecture is not the same, resulting in huge demand for testers. This research aims to build a qualitative study to Web Application Security Testing based on the opinion of Software Security Specialists, which will help testers to address their strategies within the software development lifecycle, reducing gaps in their strategy and assurance more reliable release. From Research Interview and Thematic Analysis techniques, a set of criteria has been identified and then measure for each ranking criterion. The contribution of this paper can be manipulated primarily by the testers who may benefit from the iterative software development approach to security testing. The testers will better understand the significance of the security tests and they will learn how to productively embed the tests into the development lifecycle. Last but not least, the testers may use the outcomes of this paper as support for companies struggling with a new perspective of security testing embedded in the software development process.

description: Optical vortex traps created from helical modes of light can drive fluid-borne colloidal particles in circular trajectories. Concentric circulating rings of particles formed by coaxial optical vortices form a microscopic Couette cell, in which the amount of hydrodynamic drag experienced by the spheres depends on the relative sense of the rings' circulation. Tracking the particles' motions makes possible measurements of the hydrodynamic coupling between the circular particle trains and addresses recently proposed hydrodynamic instabilities for collective colloidal motions on optical vortices.

description: Using G-structure language, a systematic, iterative formalism for computing neccessary and sufficient conditions for the existence of N arbitrary linearly independent Killing spinors is presented. The key organisational tool is the common isotropy group of the Killing spinors. The formalism is illustrated for configurations in gauged SU(2) supergravity in seven dimensions admitting at least one null Killing spinor, and the possible isotropy groups are shown to be $(SU(2)\ltimes\mathbb{R}^4)\times\mathbb{R}$, SU(2), $\mathbb{R}^5$, or the identity. The constraints associated with the existence of certain additional Killing spinors are computed, and used to derive numerous solutions. A discussion of the relevance of the formalism to the complete classification of all supersymmetric configurations in d=11 is given.

description: We study the quantum Fisher information (QFI) of acceleration, in the open quantum systems, for a two-level atom with the circular motion coupled to a massless scalar field in the Minkowski vacuum without and with a reflecting boundary in the ultra-relativistic limit. As we amplify $a$, the saturation time decreases for $θ\neqπ$, but first increases and then decreases for $θ=π$. Without a boundary, there exists a peak value of QFI with a certain time. The QFI varies with the initial state parameter $θ$, and firstly takes peak value in the ground state of the atom. The variation of QFI with respect to $θ$ gradually fades away with the evolution of time. With a boundary, the detection range of acceleration has been expanded. The QFI firstly takes the maximum in the excited state of the atom. In addition, we study the QFI of temperature for a static atom immersed in a thermal bath without and with a boundary. The relation between the saturation time and $T$ is similar to $a$. Without a boundary, the QFI of temperature is similar to that of acceleration. With a boundary, the QFI firstly takes peak value in the ground state of the atom, which is different from the behavior of acceleration. The results provide references for the detection of Unruh-like effect.

description: Kinship recognition is a challenging problem with many practical applications. With much progress and milestones having been reached after ten years - we are now able to survey the research and create new milestones. We review the public resources and data challenges that enabled and inspired many to hone-in on the views of automatic kinship recognition in the visual domain. The different tasks are described in technical terms and syntax consistent across the problem domain and the practical value of each discussed and measured. State-of-the-art methods for visual kinship recognition problems, whether to discriminate between or generate from, are examined. As part of such, we review systems proposed as part of a recent data challenge held in conjunction with the 2020 IEEE Conference on Automatic Face and Gesture Recognition. We establish a stronghold for the state of progress for the different problems in a consistent manner. This survey will serve as the central resource for the work of the next decade to build upon. For the tenth anniversary, the demo code is provided for the various kin-based tasks. Detecting relatives with visual recognition and classifying the relationship is an area with high potential for impact in research and practice.IEEE Transactions on pattern analysis and machine intelligence

description: In Malawi, maize is the major crop and food staple. Given limited off-farm employment opportunities, much-needed increases in household income for improving food security must come from gains in agricultural productivity through better technology and more profitable crops. In the past, agricultural policy promoted hybrid maize and, more recently, tobacco to increase smallholder income. This paper presents an analysis of what determines the adoption of these two crops and what kind of income effects follow from adoption. Apart from factor endowment and exposure to agroecological risks, differences in the household's access to financial and commodity markets significantly influence its cropping shares and farm income.

We compute the leading order terms that modify the non-relativistic equations of motion and use experimental results for the hyperfine transition in the ground state of the ${}^9\textrm Be^+$ ion to bound the values of the Lorentz-violating parameters $η_1$ and $η_2$ for neutrons. The resulting bounds depend on the value of the Lorenz-violating background four-vector in the laboratory frame.

description: This paper evaluates the potential of Jatropha curcas Linnaeus (Jatropha) as an alternative source of energy for rural households. The plant is said to have potential to diversify rural incomes, reclaim unproductive lands, reduce importation of fossil fuels, and consequently accumulation of green house gases in the atmosphere. A cost benefit analysis was employed to evaluate the feasibility of producing Jatropha as a biodiesel feedstock in relation to other crops in Kwale district. An IRR of 11 percent, BCR of 0.62 and a NPV of (28267.56) showed that production of Jatropha is not feasible at the moment. However we conclude that the plant has a potential to achieve its intended purpose if there is coordination in research and development along the Jatropha value chain and if technical and financial support is accorded to actors at the production level of the chain.

description: De 1997 a 2007, os programas de monetização do Título II da Agência Americana para o Desenvolvimento Internacional (USAID) venderam mais de $200 milhões de trigo e óleos vegetais não refinados destinados à ajuda alimentar em Moçambique. Este estudo tem três objectivos: 1) documentar as lições aprendidas dos programas passados de monetização em Moçambique; 2) identificar os efeitos desejados e indesejados da monetização em Moçambique; e 3) documentar sucessos indirectos em resultado da utilização da monetização em Moçambique, se os houver. Os programas de monetização em Moçambique implementados até 1997 tiveram efeitos positivos sobre o desenvolvimento de mercados e contribuíram para a segurança alimentar num período crítico. Durante os períodos posteriores, a ajuda alimentar monetizada revelou ter efeitos negativos com distribuições descoordenadas de ajuda alimentar e chegada de quantidades além da capacidade de absorção, causando a queda dos preços para os alimentos básicos produzidos localmente,contribuindo dessa forma para a volatilidade dos preços de mercados.

description: Information diffusion within financial markets plays a crucial role in the process of price formation and the propagation of sentiment and risk. We perform a comparative analysis of information transfer between industry sectors of the Chinese and the USA stock markets, using daily sector indices for the period from 2000 to 2017. The information flow from one sector to another is measured by the transfer entropy of the daily returns of the two sector indices. We find that the most active sector in information exchange (i.e., the largest total information inflow and outflow) is the {\textit{non-bank financial}} sector in the Chinese market and the {\textit{technology}} sector in the USA market. This is consistent with the role of the non-bank sector in corporate financing in China and the impact of technological innovation in the USA. In each market, the most active sector is also the largest information sink that has the largest information inflow (i.e., inflow minus outflow). In contrast, we identify that the main information source is the {\textit{bank}} sector in the Chinese market and the {\textit{energy}} sector in the USA market. In the case of China, this is due to the importance of net bank lending as a signal of corporate activity and the role of energy pricing in affecting corporate profitability. There are sectors such as the {\textit{real estate}} sector that could be an information sink in one market but an information source in the other, showing the complex behavior of different markets. Overall, these findings show that stock markets are more synchronized, or ordered, during periods of turmoil than during periods of stability.

description: Random noncommutative geometry can be seen as a Euclidean path-integral approach to the quantization of the theory defined by the Spectral Action in noncommutative geometry (NCG). With the aim of investigating phase transitions in random NCG of arbitrary dimension, we study the non-perturbative Functional Renormalization Group for multimatrix models whose action consists of noncommutative polynomials in Hermitian and anti-Hermitian matrices. Such structure is dictated by the Spectral Action for the Dirac operator in Barrett's spectral triple formulation of fuzzy spaces.The present mathematically rigorous treatment puts forward "coordinate-free" language that might be useful also elsewhere, all the more so because our approach holds for general multimatrix models. The toolkit is a noncommutative calculus on the free algebra that allows to describe the generator of the renormalization group flow -- a noncommutative Laplacian introduced here -- in terms of Voiculescu's cyclic gradient and Rota-Sagan-Stein noncommutative derivative. We explore the algebraic structure of the Functional Renormalization Group Equation and, as an application of this formalism, we find the $β$-functions, identify the fixed points in the large-$N$ limit and obtain the critical exponents of $2$-dimensional geometries in two different signatures.

description: Quantum Rabi model has been exactly solved by employing the parameter-dependent unitary transformation method in both the occupation number representation and the Bargmann space. The analytical expressions for the complete energy spectrum consisting of two double-fold degenerate sub-energy spectra are presented in the whole range of all the physical parameters. Each energy level is determined by a parameter in the unitary transformation, which obeys a highly nonlinear equation. The corresponding eigenfunction is a convergent infinite series in terms of the physical parameters. Due to the level crossings between the neighboring eigenstates at certain physical parameter values, such the degeneracies could lead to novel physical phenomena in the two-level system with the light-matter interaction.

description: In poor countries the agricultural sector is essential to growth, poverty reduction, and food security. In Sub- Saharan Africa, the agricultural sector employs 65 percent of the labor force and generates 32 per cent of GDP growth (Christian Friis Bach and all, 2008).More than half of rural employment in Sub- Saharan Africa consists of self-employed farmers, many of whom are women. Women generally own less land and the land they have is often of lower quality than the land owned by men. According to the International Development Research Centre, women in Africa only own 1 per cent of the land. Women have to contend with limited access to financial and technical resources. Women lack political influence. However the recent economic crisis that has affected the food crisis may have considerable consequences on African rural women who are mostly vulnerable in African society and may increase some challenges that can limited the African agriculture growth as women is the heart of this sector in Africa even if most of politic don’t consider them in the policies. This paper is to evaluate the major effect of this crisis on this vulnerable group In Africa and define some perspective that policies maker could use for Africa Agriculture sustainable growth.. The Descriptive analysis show that the economic crisis has increase in gender inequality in agriculture sector, increase women financial credit access lack, women farmer migration, women farmer income reduction, women land access facilities reduction and their health problem has also increase. It is clear that to solve the economic crisis impact on African agriculture for sustainable growth, policies maker should include more policies which should consider women farmers. Research also should focus more on women vulnerability in agriculture face the economic crisis.

description: Quarter sampling is a novel sensor design that allows for an acquisition of higher resolution images without increasing the number of pixels. When being used for video data, one out of four pixels is measured in each frame. Effectively, this leads to a non-regular spatio-temporal sub-sampling. Compared to purely spatial or temporal sub-sampling, this allows for an increased reconstruction quality, as aliasing artifacts can be reduced. For the fast reconstruction of such sensor data with a fixed mask, recursive variant of frequency selective reconstruction (FSR) was proposed. Here, pixels measured in previous frames are projected into the current frame to support its reconstruction. In doing so, the motion between the frames is computed using template matching. Since some of the motion vectors may be erroneous, it is important to perform a proper consistency checking. In this paper, we propose faster consistency checking methods as well as a novel recursive FSR that uses the projected pixels different than in literature and can handle dynamic masks. Altogether, we are able to significantly increase the reconstruction quality by + 1.01 dB compared to the state-of-the-art recursive reconstruction method using a fixed mask. Compared to a single frame reconstruction, an average gain of about + 1.52 dB is achieved for dynamic masks. At the same time, the computational complexity of the consistency checks is reduced by a factor of 13 compared to the literature algorithm.

description: Irrigation development is a gateway to increased agricultural, water and land productivity, increased household and national food security. However, irrigation development has been a major challenge in many developing countries, including Zimbabwe. The launch of the Fast Track Land Reform Programme (FTLRP) in 2003 ushered in new unskilled cadres and this was followed by a reduction in area developed for irrigation from 200,000ha to approximately 120,000ha. This was due to thefts, dilapidation, and vandalism of irrigation infrastructure. The government made efforts to develop and bring back the 200,000ha into operational, but little has been achieved. To assess irrigation development post FTLRP, a case study was done in Goromonzi District. Using a Trend Analysis to assess the trend in irrigation funding, a downward trend was revealed. A Gross Margin Analysis, modeled via the Business Coefficient Expansion Factor (BCEF) to evaluate productivity and profitability of the irrigation enterprises showed that farmers performed below average and major irrigation crops were below the ideal BCEF threshold of 2.5, suggesting non-profitability of irrigation enterprises. An analysis on infrastructure revealed that most of it was partially or non-functional, hence farmers reduced area under irrigation. The study also revealed non-accessibility of training services by farmers. The study concluded that inadequate irrigation funding, low irrigation productivity, nonprofitability of irrigation enterprises, poor cost recovery mechanisms and lack of relevant training has led to low irrigation development. The study recommends that national governments should formulate and hold sound irrigation development strategies and encouraged to partner with public and private institutions in defining and implementing such comprehensive strategies for sustainable irrigation development.
