description: Over the past decade, experimental microscopy and spectroscopy have made significant progress in the study of the morphological, optical, electronic and transport properties of materials. These developments include higher spatial resolution, shorter acquisition times, more efficient monochromators and electron analysers, improved contrast imaging and advancements in sample preparation techniques. These advances have driven the need for more accurate theoretical descriptions and predictions of material properties. Computer simulations based on first principles and Monte Carlo methods have emerged as a rapidly growing field for modeling the interaction of charged particles, such as electron, proton and ion beams, with various systems, such as slabs, nanostructures and crystals. This report delves into the theoretical and computational approaches to modeling the physico-chemical mechanisms that occur when charged beams interact with a medium. These mechanisms encompass single and collective electronic excitation, ionization of the target atoms and the generation of a secondary electron cascade that deposits energy into the irradiated material. We show that the combined application of ab initio methods, which are able to model the dynamics of interacting many-fermion systems, and Monte Carlo methods, which capture statistical fluctuations in energy loss mechanisms by random sampling, proves to be an optimal strategy for the accurate description of charge transport in solids. This joint quantitative approach enables the theoretical interpretation of excitation, loss and secondary electron spectra, the analysis of the chemical composition and dielectric properties of solids and contributes to our understanding of irradiation-induced damage in materials, including those of biological significance.

description: We present a simple yet highly generalizable method for explaining interacting parts within a neural network's reasoning process. First, we design an algorithm based on cross derivatives for computing statistical interaction effects between individual features, which is generalized to both 2-way and higher-order (3-way or more) interactions. We present results side by side with a weight-based attribution technique, corroborating that cross derivatives are a superior metric for both 2-way and higher-order interaction detection. Moreover, we extend the use of cross derivatives as an explanatory device in neural networks to the computer vision setting by expanding Grad-CAM, a popular gradient-based explanatory tool for CNNs, to the higher order. While Grad-CAM can only explain the importance of individual objects in images, our method, which we call Taylor-CAM, can explain a neural network's relational reasoning across multiple objects. We show the success of our explanations both qualitatively and quantitatively, including with a user study. We will release all code as a tool package to facilitate explainable deep learning.

description: Nuclear-magnetic-resonance (NMR) studies were performed in Na$_{0.7}$CoO$_2$ to investigate its magnetic properties from the microscopic point of view. Na$_{0.7}$CoO$_2$ is a starting compound of the recently discovered superconductor Na$_{0.35}$CoO$_2$$\cdot 1.3$H$_2$O, in which Co atoms form a triangular structure. Although $^{23}$Na-NMR results show no magnetic anomaly down to 1.5 K, Knight shift ($^{23}K$) and $^{23}(1/T_1T)$ of $^{23}$Na continue to increase, suggestive of the vicinity of the magnetic phase. From the relation between $^{23}K$ and $^{23}(1/T_1T)$, it is shown that ferromagnetic fluctuations are dominant below 100 K. In addition to the ferromagnetic correlations, antiferromagnetic fluctuations are also developed in a low temperature region below 4 K. Magnetic fluctuations suggested by our experiment are discussed.

description: In Egypt, the relocation of residents of informal areas of housing into “proper” living environments is presented as a major political achievement offering citizens a much-improved quality of life. Therefore, it is not surprising that, following the Arab Uprisings, the current regime is widely publicizing relocation projects as success stories on TV and social media. As a way of garnering legitimization and securing stability, this official representation is reshaping the residents’ urban life and evoking narratives of slum dwellers’ transformation into respected citizens. Tackling a new area of interdisciplinary research between urban studies and media and communication studies, this article investigates the portrayal in mainstream media channels and social media platforms of two relocation projects (Al-Asmarat in Cairo and Al-Max in Alexandria), contrasting them with the residents’ perceptions of their new homes and their efforts to produce counter-imagery. The authors argue that both the state-dominated representation of the Al-Asmarat resettlement as an ideal solution to the crisis of informal settlements, as well as the more bottom-up construction of the Al-Max community as a picturesque fishing community, do not reflect the material experience of the inhabitants—despite it being presented as such in nationwide reporting. The effective centering of the public debate around the mediatized images has thus deflected criticism and enabled urban development projects to be positioned to legitimize the current rule despite the shortcomings of their implementation.

description: The production of K+ and of K- mesons in heavy-ion collisions at beam energies of 1 to 2 AGeV has systematically been investigated with the Kaon Spectrometer KaoS. The ratio of the K+ production excitation function for Au+Au and for C+C reactions increases with decreasing beam energy, which is expected for a soft nuclear equation-of-state. A comprehensive study of the K+ and of the K- emission as a function of the size of the collision system, of the collision centrality, of the kaon energy, and of the polar emission angle has been performed. The K-/K+ ratio is found to be nearly constant as a function of the collision centrality and can be explained by the dominance of strangeness exchange. On the other hand the spectral slopes and the polar emission patterns are different for K- and for K+. Furthermore the azimuthal distribution of the particle emission has been investigated. K+ mesons and pions are emitted preferentially perpendicular to the reaction plane as well in Au+Au as in Ni+Ni collisions. In contrast for K- mesons in Ni+Ni reactions an in-plane flow was observed for the first time at these incident enegies.

description: Topological protection is employed in fault-tolerant error correction and in developing quantum algorithms with topological qubits. But, topological protection intrinsic to models being simulated, also robustly protects calculations, even on NISQ hardware. We leverage it by simulating Kitaev-inspired models on IBM quantum computers and accurately determining their phase diagrams. This requires constructing conventional quantum circuits for Majorana braiding to prepare the ground states of Kitaev-inspired models. The entanglement entropy is then measured to calculate the quantum phase boundaries. We show how maintaining particle-hole symmetry when sampling through the Brillouin zone is critical to obtaining high accuracy. This work illustrates how topological protection intrinsic to a quantum model can be employed to perform robust calculations on NISQ hardware, when one measures the appropriate protected quantum properties. It opens the door for further simulation of topological quantum models on quantum hardware available today.

description: The rapid advancement of autonomous driving technology is accompanied by substantial challenges, particularly the reliance on remote task execution without ensuring a reliable and accurate returned results. This reliance on external compute servers, which may be malicious or rogue, represents a major security threat. While researchers have been exploring verifiable computing, and replication-based task verification as a simple, fast, and dependable method to assess the correctness of results. However, colluding malicious workers can easily defeat this method. Existing collusion detection and mitigation solutions often require the use of a trusted third party server or verified tasks which may be hard to guarantee, or solutions that assume the presence of a minority of colluding servers. We propose SERENE, a collusion resilient replication-based verification framework that detects, and mitigates colluding workers. Unlike state-of-the-art solutions, SERENE uses a lightweight detection algorithm that detects collusion based on a single verification task. Mitigation requires a two stage process to group the workers and identifying colluding from honest workers. We implement and compare SERENE's performance to Staab et. al, resulting in an average of 50\% and 60\% accuracy improvement in detection and mitigation accuracy respectively.

description: This second paper of two companion papers on the estimation of power spectra specializes to the topic of estimating galaxy power spectra at large, linear scales using maximum likelihood methods. As in the first paper, the aims are pedagogical, and the emphasis is on concepts rather than technical detail. The paper covers most of the salient issues, including selection functions, likelihood functions, Karhunen-Loeve compression, pair-integral bias, Local Group flow, angular or radial systematics (arising for example from extinction), redshift distortions, quadratic compression, decorrelation, and disentanglement. The procedures are illustrated with results from the IRAS PSCz survey. Most of the PSCz graphics included in this paper have not been published elsewhere.

description: Estudou-se a rentabilidade da atividade leiteira na região de Lavras/MG, analisando a influência do nível tecnológico sobre o custo de produção do leite. Foram identificados os componentes com maior influência sobre os custos finais da atividade e calculado o ponto de equilíbrio. Os dados, provenientes de 17 sistemas de produção, representando os níveis tecnológicos baixo, médio e alto, foram coletados mensalmente, entre janeiro de 2004 e dezembro de 2005. Considerou-se a margem bruta, a margem líquida e o resultado (lucro ou prejuízo) como indicadores de eficiência econômica. O nível tecnológico influenciou os itens componentes do custo operacional efetivo da atividade leiteira, bem como o custo total de produção do leite - a lucratividade e rentabilidade. Os sistemas de produção com nível tecnológico médio apresentaram o menor custo total unitário. A margem líquida positiva nos três níveis tecnológicos indica que os pecuaristas conseguem produzir a médio prazo; e por apresentar resultado negativo, os pecuaristas que adotaram médio nível tecnológico, a longo prazo, estão se descapitalizando.---------------------------------------------The profitability of milk activity was studied in the region of Lavras, MG by analyzing the influence of technological level on milk production cost. The components with major influence on the final activity cost were identified, and the break-even was calculated. Monthly data from 17 production systems representing the low, medium and high technological levels were taken from January 2004 to December 2005. Gross margin and net margin (profit or loss) were considered as indicators of economical efficiency. The technological level had impact on the effective operational cost of milk activity as well as on the total costs of milk production – rentability and profitability. Production systems with medium technological level had the lowest total unitary cost. Positive net margin in the three technological levels shows that the farmers can produce in medium term also, due to negative results, the farmers who used the medium technological level at long term are losing money.

description: This paper investigates the problem of matching a MIDI file against a large database of piano sheet music images. Previous sheet-audio and sheet-MIDI alignment approaches have primarily focused on a 1-to-1 alignment task, which is not a scalable solution for retrieval from large databases. We propose a method for scalable cross-modal retrieval that might be used to link the Lakh MIDI dataset with IMSLP sheet music data. Our approach is to modify a previously proposed feature representation called a symbolic bootleg score to be suitable for hashing. On a database of 5,000 piano scores containing 55,000 individual sheet music images, our system achieves a mean reciprocal rank of 0.84 and an average retrieval time of 25.4 seconds.

description: Neste trabalho tem-se como objetivo caracterizar a estrutura de governança da cadeia produtiva do leite em Rolim de Moura, município do Estado de Rondônia, sob a perspectiva da economia dos custos de transação. Para atingir tal objetivo, realizou-se uma investigação descritiva e uma pesquisa de campo envolvendo todos os segmentos dessa cadeia. Nesse aspecto, observou-se que na região a maioria das estruturas de governança entre os atores presentes ocorre via mercado em função, principalmente, no caso do produtor com a indústria processadora, da confiança construída ao longo do tempo e do conhecimento da atividade. Entretanto, é de se ressaltar que embora essa confiança e conhecimento tem permitido a sustentação de vantagens competitivas das empresas na região, nota-se que uma empresa já vem buscando estabelecer outros mecanismos de governança com seus parceiros através de alianças estratégicas afim de assegurar o recebimento de um produto com qualidade, quantidade e preço justo. Mas, para toda a cadeia ainda há a necessidade de uma melhor coordenação e articulação dos agentes para que todos possam conseguir obter os benefícios de uma cadeia com uma governança adequada e que reflita em um bom desempenho competitivo.----------------------------------------------This work has been intended to characterize the structure of governance of the production chain of milk in Rolim de Moura, municipality of the state of Rondônia, on the prospect of the economy of the costs of transaction. To achieve this objective, an investigation took place descriptive and a search of field involving all segments of that chain. In this respect, it was observed that the region most of the structures of governance among the actors present occurs via market in function, especially in the case of the producer with industry processing, confidence built over time and the knowledge of the activity. However, it is to emphasize that although this confidence and knowledge has allowed support the competitive advantages of companies in the region, notes that a company is already trying to establish other mechanisms of governance with its partners through strategic alliances in order to ensure the receipt of a product with quality, quantity and fair price. But for the entire chain there is still a need for better coordination and linkage of the players so that everyone can achieve the benefits a chain with proper governance and that reflects on a good performance competitive.

description: The primary goal of a recommender system is often known as "helping users find relevant items", and a lot of recommendation algorithms are proposed accordingly. However, these accuracy-oriented methods usually suffer the problem of recommendation bias on popular items, which is not welcome to not only users but also item providers. To alleviate the recommendation bias problem, we propose a generic rank aggregation framework for the recommendation results of an existing algorithm, in which the user- and item-oriented ranking results are linearly aggregated together, with a parameter controlling the weight of the latter ranking process. Experiment results of a typical algorithm on two real-world data sets show that, this framework is effective to improve the recommendation fairness of any existing accuracy-oriented algorithms, while avoiding significant accuracy loss.

description: The study aims to validate an instrument to measure money management intention based on six processes and three cognitive stages of change according to the transtheoretical model of change. A total of one thousand sixty-three Thai undergraduate students from three public and three private universities in Bangkok and Nakorn Pathom provinces in Thailand were randomly recruited in the various validation steps including confirmatory factor analysis, test-retest reliability method, concurrent validation, convergent validation and discriminant validation. The results confirmed the validity and reliability of the eighteen items based on the six components among the general university students; CFA showed acceptable fit indices; χ2 = 331.65, χ2/df = 2.88, CFI = .91, GFI = .87, RMSEA = .06, scoring separately in each process of change. Moreover, saving from Saving Scale and Machiavellianism from SD3-TH indicated the most robust relationships with all developing measures significantly. Convergent and discriminant validations were met the critical criteria. This validated measure was labeled as MMIQ-TTM. The present study confirms the usefulness of six processes and three stages in measuring money management intention at the early cognitive stage before performing behavioral changes in the future action stages among undergraduate students.

description: A reforma agrária faz surgir uma nova categoria social e mosaicos na paisagem, em substituição às monoculturas. Nos assentamentos rurais ocorre uma reconstrução do agricultor, que pelo resgate do seu habitus cultural produz ao menos uma parte do autoconsumo alimentar. Todavia, a fixação no território obriga o assentamento a articulações com a dinâmica rural macroenvolvente e o enreda na lógica da monocultura que, em termos históricos e paradoxalmente, foi a mesma que engendrou a desfiliação social de outrora e a necessidade de luta pela terra. Este artigo discute, em meio a esta problemática, a agricultura voltada ao autoconsumo alimentar em consideração a alguns princípios agroecológicos. Retoma-se, ao final, que com o apoio de políticas municipais voltadas a este tipo de produção (de alimentos), pode ser configurada uma estratégia de desenvolvimento rural frente à invasão da cana nos lotes agrícolas.-----------------------------------------------The agrarian reform makes to appear a new social category and mosaics in the landscape, in substitution to the cultivations.

However, the setting in the territory compels the nesting joints with the macroinvolving agricultural dynamics and tangles it in the logic of the cultivation that, in historical terms and paradoxicalally, was the same one that it produced the social disfiliation of long ago and the necessity of fight for the land. This article argues, in way to this problematic one, the agriculture directed to the production familie´s selfconsume to feed in consideration to some agroecology principles. It is retaken, to the end, that with the support of municipal politics come back to this type of production (of foods), can be configured a strategy of agricultural development front to the invasion of the sugar cane in the agricultural lots.

Convergence of lattice trees to super-brownian motion above the critical dimension
Creators: name: Holmes, Mark
Publisher: name: University of British Columbia
Year: 2009

description: A lattice tree is a finite connected set of lattice bonds containing no cycles. Lattice trees are interesting combinatorial objects and an important model for branched polymers in polymer chemistry and physics. In addition they provide an interesting example of critical phenomena in statistical physics with similar properties to models such as self-avoiding walks and percolation. We use the lace expansion to prove asymptotic formulae for the Fourier transform of the r-point functions (quantities which count critically weighted trees containing r fixed points) for a spread-out model of lattice" trees in ℤ[sup d] for d > 8. Our results therefore provide additional evidence in support of the critical dimension d[sub c] = 8. The spread out model allows bonds between vertices x,y ∈ ℤ[sup d] with x-y ∞ ≤ L, providing a small parameter L [sup –d/2] needed for convergence of the lace expansion. We extend the inductive approach (to the lace expansion on an interval) of van der Hofstad and Slade [19] to prove convergence of the Fourier transform of the 2-point function (r = 2). We then proceed by induction on r, equipped with the lace expansion on a tree [21]. The asymptotic formulae for the r-point functions imply convergence of certain expectations of the spread out lattice trees model formulated as a measure valued process, to those of the canonical measure of super-Brownian motion. Appealing to the hypothesis of universality, we expect that the results also hold for the nearest neighbour model. Our results together with the convergence of the survival probability would imply convergence of the finite-dimensional distributions of our process to those of the canonical measure of super-Brownian motion. Convergence of the survival probability remains an open problem.

description: Networks such as the Internet are essential for our connected world. Quantum computing poses a threat to this heterogeneous infrastructure since it threatens fundamental security mechanisms. Therefore, a migration to post-quantum-cryptography (PQC) is necessary for networks and their components. At the moment, there is little knowledge on how such migrations should be structured and implemented in practice. Our systematic literature review addresses migration approaches for IP networks towards PQC. It surveys papers about the migration process and exemplary real-world software system migrations. On the process side, we found that terminology, migration steps, and roles are not defined precisely or consistently across the literature. Still, we identified four major phases and appropriate substeps which we matched with also emerging archetypes of roles. In terms of real-world migrations, we see that reports used several different PQC implementations and hybrid solutions for migrations of systems belonging to a wide range of system types. Across all papers we noticed three major challenges for adopters: missing experience of PQC and a high realization effort, concerns about the security of the upcoming system, and finally, high complexity. Our findings indicate that recent standardization efforts already push quantum-safe networking forward. However, the literature is still not in consensus about definitions and best practices. Implementations are mostly experimental and not necessarily practical, leading to an overall chaotic situation. To better grasp this fast moving field of (applied) research, our systematic literature review provides a comprehensive overview of its current state and serves as a starting point for delving into the matter of PQC migration.

description: The field-induced magnetic order in the singlet-ground-state system CsFeCl$_3$ has been studied by measuring magnetization and neutron diffraction. The field dependence of intensity for the neutron magnetic reflection has clearly demonstrated that the field-induced ordered phase is described by the order parameter $$. A condensate growth of magnons is investigated through the temperature dependence of $M_z$ and $M_{\perp}$, and this ordering is discussed in the context of a magnon Bose-Einstein condensation. Development of the coherent state and the static correlation length has been observed in the incommensurate phase in the field region of $5 < H < 6$ T at 1.8 K. At $H > H_{\rm c}$, a satellite peak was found in coexistence with the commensurate peak at the phase boundary around 10 T, which indicates that the tilt of the c-axis would be less than $\sim 0.5^{\circ}$ in the whole experiments.

description: We theoretically studied spin dependent electron transport perpendicular-to-plain (CPP) in magnetic laminated multilayered structures by using Kubo formalism. We took into account not only bulk scattering, but the interface resistance due to both specular and diffuse reflection and also spin conserving and spin-flip processes. It was shown that spin-flip scattering at interfaces substantially reduces the value of GMR. This can explain the experimental observations that the CPP GMR ratio for laminated structures only slightly increases as compared to non-laminated ones despite lamination induces a significant increase in CPP resistance.

Mixed QCD-electroweak corrections to on-shell Z production at the LHC

description: We present the first complete calculation of mixed QCD-electroweak corrections to the production of on-shell $Z$ bosons in hadron collisions and their decays to massless charged leptons. Our computation is fully differential with respect to final state QCD partons and resolved photons, allowing us to compute any infra-red safe observable pertinent to the $pp \to Z \to l^+ l^-$ process in the approximation that the $Z$ boson is on shell. Although mixed QCD-electroweak corrections are small, at about the per mill level, we observe that the interplay between QCD-QED and QCD-weak contributions is subtle and observable-dependent. It is therefore not possible to avoid computing one or the other if ${\cal O}(α_{EW} α_s)$ precision is desired.

description: The production cross sections of fragmentation-evaporation residues in the reaction Pb+p at 500A MeV have been measured using the inverse-kinematics method and the FRS spectrometer (GSI). Fragments were identified in nuclear charge using ionisation chambers. The mass identification was performed event-by-event using the B-rho - TOF - Delta-E technique. Although partially-unresolved ionic charge states induced an ambiguity on the mass of some heavy fragments, production rates could be obtained with a high accuracy by systematically accounting for the polluting ionic charge states. The contribution of multiple reactions in the target was subtracted using a new, partly self-consistent code. The isobaric distributions are found to have a shape very close to the one observed in experiments at higher energy. Kinematic properties of the fragments were also measured. The total and the isotopic cross sections, including charge-pickup cross sections, are in good agreement with previous measurements. The data are discussed in the light of previous spallation measurements, especially on lead at 1 GeV.

description: O artigo analisa as especificidades e as estratégias competitivas do arranjo produtivo fumageiro, localizado na Região do Vale do Rio Pardo, Estado do Rio Grande do Sul. Historicamente, a cadeia produtiva fumageira é a atividade que dinamiza a economia regional. Porém, com o aumento das campanhas antitabagistas e a assinatura de acordos internacionais para controle do consumo de cigarros, estudos sobre concentração e dependência produtiva são necessários para que estas economias possam analisar oportunidades para promover a diversificação da produção. Neste sentido, o estudo baseou-se nas abordagens teóricas sobre arranjos produtivos locais e realizou entrevistas em profundidade com os principais agentes que atuam direta e indiretamente no arranjo fumageiro. A partir das entrevistas delineou-se o cenário atual da produção e consumo de tabaco, bem como as expectativas desses atores para o arranjo produtivo local na próxima década. Na opinião de todos os entrevistados, o consumo de cigarros tende a continuar elevado e a produção de tabaco permanecerá a principal fonte de renda para a região estudada, com poucas alternativas viáveis, considerando as especificidades geográficas, produtivas e culturais. ----------------------------------------------The paper analyzes the specificities and competitive strategies of the tobacco productive arrangement in the Vale do Rio Pardo region, located in Rio Grande do Sul State. Historically, the tobacco productive chain generates dynamism in the local economy. However, with the growing of anti-tobacco campaigns and the signature of international traits related to the control cigarettes consumption, studies about productive concentration and dependency are necessary to analyze opportunities to promote production diversification. In that sense, the present study is based on theoretical approaches about local productive arrangements, and in-depth interviews have been conducted with the main agents which act direct and indirectly in the tobacco arrangement. Departing from the interviews, we have delineated the scenario of currently tobacco production and consumption, as well as those actors’ expectations for the local productive arrangement in the next decade. The interviewers believe that cigarettes consumption tends to remain in high levels and tobacco production will continue the main source of income in the studied area. Few alternatives seem viable, considering the cultural, productive and geographical specificities.

description: This paper introduces a representative-based approach for distributed learning that transforms multiple raw data points into a virtual representation. Unlike traditional distributed learning methods such as Federated Learning, which do not offer human interpretability, our method makes complex machine learning processes accessible and comprehensible. It achieves this by condensing extensive datasets into digestible formats, thus fostering intuitive human-machine interactions. Additionally, this approach maintains privacy and communication efficiency, and it matches the training performance of models using raw data. Simulation results show that our approach is competitive with or outperforms traditional Federated Learning in accuracy and convergence, especially in scenarios with complex models and a higher number of clients. This framework marks a step forward in integrating human intuition with machine intelligence, which potentially enhances human-machine learning interfaces and collaborative efforts.
