description: This paper presents a pioneering approach for simulation of economic activity, policy implementation, and pricing of goods in token economies. The paper proposes a formal analysis framework for wealth distribution analysis and simulation of interactions between economic participants in an economy. Using this framework, we define a mechanism for identifying prices that achieve the desired wealth distribution according to some metric, and stability of economic dynamics.
 The motivation to study tokenomics theory is the increasing use of tokenization, specifically in financial infrastructures, where designing token economies is in the forefront. Tokenomics theory establishes a quantitative framework for wealth distribution amongst economic participants and implements the algorithmic regulatory controls mechanism that reacts to changes in economic conditions.
 In our framework, we introduce a concept of tokenomic taxonomy where agents in the economy are categorized into agent types and interactions between them. This novel approach is motivated by having a generalized model of the macroeconomy with controls being implemented through interactions and policies. The existence of such controls allows us to measure and readjust the wealth dynamics in the economy to suit the desired objectives.

description: O objetivo deste trabalho foi analisar os indicadores de rentabilidade da produção de duas importantes olerícolas (alface e cenoura) na região de Bebedouro-SP, como subsídio à tomada de decisão quanto à adoção de sistemas orgânicos por parte de produtores da região. Foi analisado um grupo de 20 produtores do município, que foram submetidos à capacitação técnica e gerencial por parte do SEBRAE-SP, após análise do potencial de mercado e produção na região. Do total, sete produtores aderiram integralmente ao sistema de produção, dando início ao processo atendimento das normas propostas de certificação. Para a análise de rentabilidade foram determinados os seguintes indicadores: custo operacional efetivo (COE), margem bruta sobre o custo operacional, lucro operacional sobre o COE, custo e lucro unitários, ponto de nivelamento e índice de lucratividade. Os resultados mostraram que para ambos os cultivos os lucros econômicos foram positivos, embora o cultivo de alface se mostre mais rentável (77,3%) que a cenoura (33,7%), apontando para a viabilidade da adoção de sistemas orgânicos no município. É importante destacar que os produtores ainda não são certificados, portanto não foram incluídos os custos de certificação, mas dada estimativa do custo de certificação, os indicadores de rentabilidade não são afetados significativamente. -----The aim of this work was to analyze the economic results of lettuce and carrot crops in organic production system in the county of Bebedouro-SP, to subsidize producers about the adoption of organic systems. It were analyzed a group of 20 farmers, that received technical and management training by SEBRAE-SP. From these producers, 7 of them adopted integrally the organic system and had began to attend the certification rules. For the profitability analysis the following indicators was determined: effective operational costs (EOC), gross margin, operational profit, unitary cost em profit, profitability rate and break even point. The results showed that both crops present positive profit, although lettuce crop profit was higher (77.3%) than the carrot crop one (33.7%). The products are not certified yet, therefore the certification cost was not included in this study, but the results do not change, even including estimated certification cost.

description: Evidence has accumulated suggesting the clustering of radio loud quasars is greater than for radio quiet quasars. We interpret these results in a context in which the fraction of radio loud quasar formation is less than or equal to that for radio quiet quasars for all environments and redshift. Because we assume that post-merger cold gas onto large black holes produces either a radio loud or a radio quiet quasar, we show that for largest black hole masses that live in largest dark matter halos, fRLQ approaches 0.5 from below but does not exceed it, such that in rich clusters the formation of a radio loud quasar tends to be equally likely to occur as a radio quiet quasar. In dark matter halos with smaller mass, by contrast, radio quiet quasars are more likely to form and the likelihood increases inversely with dark matter halo mass. As a result, averaging over a population of radio loud and radio quiet quasars will necessarily generate lower average black hole masses for the radio quiet subgroup. Hence, despite the fact that the formation of radio quiet quasars is preferred over radio loud quasars in any environment, at any mass scale, at any luminosity, or redshift, averaging over a range of radio loud quasars will give the appearance they are preferred in cluster environments over radio quiet quasars. We show how this also accounts for the order of magnitude difference in the total number of jetted active galaxies compared to non-jetted counterparts.

description: A crescente elevação de custos econômicos e ambientais das técnicas convencionais de produção agrícola tem levado ao desenvolvimento de formas alternativas de produção de menor impacto ambiental e menores custos de produção, sendo a mais comum, o plantio direto. O objetivo deste estudo foi analisar a rentabilidade da cultura do milho sob dois tipos de manejo, o sistema convencional e de plantio direto na região de Itapetininga, Estado de São Paulo. Os indicadores determinados foram: custo operacional efetivo, custo operacional total, receita bruta, margem bruta, ponto de nivelamento, preço de equilíbrio, lucro operacional e índice de lucratividade. Verificou-se maior economicidade na adoção do sistema de plantio direto, na região estudada, em função do menor custo operacional . O aumento dos custos com herbicida neste sistema e os custos fixos da colheitadeira não foram compensados pelos maiores custos operacionais do sistema de plantio convencional. ----The growing economic and environmental costs of conventional techniques of agricultural production affords the development of alternative systems production of lower environmental impact and production costs, and the most common technique is the no-tillage system. The aim of this work was to analyze to profitability rate of corn crop under two production systems, the conventional system and no-tillage system, in the regions of Itapetininga, São Paulo State. The indicators were: cost operational effective, total operational cost, gross revenue, gross margin, break even point, operational profit and profitability rate. Greater economy was verified in no tillage system in reason of lower operational costs and same yield. The increase of herbicide costs and fixed costs of grain harvester self propelling in this system were not compensated by the largest operational costs of conventional system.

description: We study the spin $\frac12$ hadronic state in quenched lattice QCD to search for a possible $S=+1$ pentaquark resonance. Simulations are carried out on $8^3\times 24$, $10^3\times 24$, $12^3\times 24$ and $16^3\times 24$ lattices at $β$=5.7 at the quenched level with the standard plaquette gauge action and Wilson quark action. We adopt two independent operators with I=0 and $J^P=\frac12$ to construct a $2\times 2$ correlation matrix. After the diagonalization of the correlation matrix, we successfully obtain the energies of the ground-state and the 1st excited-state in this channel. The volume dependence of the energies suggests the existence of a possible resonance state slightly above the NK threshold in I=0 and $J^P=\frac12^-$ channel.

description: Deep Neural Network (DNN) applications with edge computing presents a trade-off between responsiveness and computational resources. On one hand, edge computing can provide high responsiveness deploying computational resources close to end devices, which may be prohibitive for the majority of cloud computing services. On the other hand, DNN inference requires computational power to be executed, which may not be available on edge devices, but a cloud server can provide it. To solve this problem (trade-off), we partition a DNN between edge device and cloud server, which means the first DNN layers are processed at the edge and the other layers at the cloud. This paper proposes an optimal partition of DNN, according to network bandwidth, computational resources of edge and cloud, and parameter inherent to data. Our proposal aims to minimize the inference time, to allow high responsiveness applications. To this end, we show the equivalency between DNN partitioning problem and shortest path problem to find an optimal solution, using Dijkstra's algorithm.

description: The dynamics of two coupled piece-wise linear one-dimensional monostable maps is investigated. The single map is associated with Poincare section of the FitzHugh-Nagumo neuron model. It is found that a diffusive coupling leads to the appearance of chaotic attractor. The attractor exists in an invariant region of phase space bounded by the manifolds of the saddle fixed point and the saddle periodic point. The oscillations from the chaotic attractor have a spike-burst shape with anti-phase synchronized spiking.

Spin of the M87 black hole

description: Spin measurement of the 6.5 billion solar mass black hole in M87 from the Event Horizon Telescope image is the latest in a series that span a wide range in values, but that tend to share the feature of co-rotation between the accretion flow and black hole. The spin paradigm for black holes predicts very high black hole spin which in that framework was produced in its last significant merger. High black hole spin appears to be ruled out in the gap paradigm, however, which predicts early formation with a mass already in excess of 4 billion solar masses. In this picture, the black hole experienced slow evolution as it departed from its original radio quasar phase and over billions of years not only failed to double its mass but also fell short of regaining its original high spin, such that it is now compatible with a co-rotating accreting black hole whose dimensionless spin fits best in the range 0.2 < a < 0.5.

description: The identification of the astrophysical site and the specific conditions in which r-process nucleosynthesis takes place remain unsolved mysteries of astrophysics. The present paper emphasizes some important future challenges faced by nuclear physics in this problem, particularly in the determination of the radiative neutron capture rates by exotic nuclei close to the neutron drip line and the fission probabilities of heavy neutron-rich nuclei. These quantities are particularly relevant to determine the composition of the matter resulting from the decompression of initially cold neutron star matter. New detailed r-process calculations are performed and the final composition of ejected inner and outer neutron star crust material is estimated. We discuss the impact of the many uncertainties in the astrophysics and nuclear physics on the final composition of the ejected matter. The similarity between the predicted and the solar abundance pattern for A > 140 nuclei as well as the robustness of the prediction with varied input parameters makes this scenario one of the most promising that deserves further exploration.

description: Smart city is one of the most known Internet of Things (IoT) applications. The smart city services improve user's daily lives. However, security and privacy issues are slowing down their adoption. In addition, the characteristics of IoT devices, applications and users make security implementation of the considered applications a challenging task. To address these issues, we present, in this paper, a new context-aware security and privacy architecture for the IoT. Thanks to the "as a service" approach, this new architecture will be user-centric. It will also support known context-aware security issues: dynamicity, flexibility. In addition, it will address mobility, customization of security and privacy services, and support for generic IoT applications, particularly for smart city. To do so, a knowledge plane allowing effective management of context-awareness is proposed. A security and privacy plane allowing better implementation of context-aware security and privacy mechanisms is also proposed. This will be done through dynamic composition of context-based micro services. The role of the different components of these two planes are also described.

description: The combination of the first-year Wilkinson Microwave Anisotropy Probe (WMAP) data with other finer scale cosmic microwave background (CMB) experiments (CBI and ACBAR) and two structure formation measurements (2dFGRS and Lyman $α$ forest) suggest a $Λ$CDM cosmological model with a running spectral power index of primordial density fluctuations. Motivated by this new result on the index of primordial power spectrum, we present the first study on the predicted lensing probabilities of image separation in a spatially flat $Λ$CDM model with a running spectral index (RSI-$Λ$CDM model). It is shown that the RSI-$Λ$CDM model suppress the predicted lensing probabilities on small splitting angles of less than about 4$^{''}$ compared with that of standard power-law $Λ$CDM (PL-$Λ$CDM) model.

description: We present 3D full-sphere supernova simulations of non-rotating low-mass (~9 Msun) progenitors, covering the entire evolution from core collapse through bounce and shock revival, through shock breakout from the stellar surface, until fallback is completed several days later. We obtain low-energy explosions [~(0.5-1.0)x 10^{50} erg] of iron-core progenitors at the low-mass end of the core-collapse supernova (LMCCSN) domain and compare to a super-AGB (sAGB) progenitor with an oxygen-neon-magnesium core that collapses and explodes as electron-capture supernova (ECSN). The onset of the explosion in the LMCCSN models is modelled self-consistently using the Vertex-Prometheus code, whereas the ECSN explosion is modelled using parametric neutrino transport in the Prometheus-HOTB code, choosing different explosion energies in the range of previous self-consistent models. The sAGB and LMCCSN progenitors that share structural similarities have almost spherical explosions with little metal mixing into the hydrogen envelope. A LMCCSN with less 2nd dredge-up results in a highly asymmetric explosion. It shows efficient mixing and dramatic shock deceleration in the extended hydrogen envelope. Both properties allow fast nickel plumes to catch up with the shock, leading to extreme shock deformation and aspherical shock breakout. Fallback masses of 40 km/s and a NS spin period of ~30 ms, both not largely different from those of the Crab pulsar at birth.

description: As mudanças institucionais ocorridas a partir de 1990 obrigaram os agentes da cadeia do trigo a segmentar seus produtos de forma a concorrer com os produtos importados que adentraram no mercado brasileiro. Nesse processo se fez necessário a implantação de novos sistemas de classificação de trigo por qualidade. Esse artigo tem por objetivo analisar o impacto desses novos padrões sobre os custos de transação e, conseqüentemente, sobre as estruturas de governança que regulavam essas transações. Foram utilizados aportes teóricos ligados a Nova Economia Institucional, destacando-se a Economia dos Custos de Transação e a Economia dos Custos de Mensuração. Verificou-se que os padrões de qualidade têm permitido a coordenação da produção de trigo pelos elos a jusante sem a utilização de estruturas de governança mais integradas.-----The institutional changes which took place by 1990 forced the players operating on the Brazilian wheat chain to segment their products in a way to compete with the imported products. This process demanded the establishment of a new classification system for the wheat quality. This paper aims to explain how the new quality standards impacted on transaction costs, and therefore, on the governance structures which regulated the transactions on the Brazilian market. With this goal this paper will be referring to theoretical approaches related to the New Institutional Economics, as the Transaction Cost Economics and the Measurement Cost Economics. It was observed that the quality standards have allowed agents on milling and processing tiers to coordinate the production of wheat without the use of more integrated forms of governance structures.

description: Policy gradient methods equipped with deep neural networks have achieved great success in solving high-dimensional reinforcement learning (RL) problems. However, current analyses cannot explain why they are resistant to the curse of dimensionality. In this work, we study the sample complexity of the neural policy mirror descent (NPMD) algorithm with deep convolutional neural networks (CNN). Motivated by the empirical observation that many high-dimensional environments have state spaces possessing low-dimensional structures, such as those taking images as states, we consider the state space to be a $d$-dimensional manifold embedded in the $D$-dimensional Euclidean space with intrinsic dimension $d\ll D$. We show that in each iteration of NPMD, both the value function and the policy can be well approximated by CNNs. The approximation errors are controlled by the size of the networks, and the smoothness of the previous networks can be inherited. As a result, by properly choosing the network size and hyperparameters, NPMD can find an $ε$-optimal policy with $\widetilde{O}(ε^{-\frac{d}α-2})$ samples in expectation, where $α\in(0,1]$ indicates the smoothness of environment. Compared to previous work, our result exhibits that NPMD can leverage the low-dimensional structure of state space to escape from the curse of dimensionality, explaining the efficacy of deep policy gradient algorithms.

description: We analyze possible singularities in the $J/ψΛ$ invariant mass distribution of the $Ξ^-_{b}~\to~K^- J/ψΛ$ process via triangle loop diagrams. Triangle singularities in the physical region are found in 18 different triangle loop diagrams. Among those with $Ξ^*$-charmonium-$Λ$ intermediate states, the one from the $χ_{c1} Ξ(2120) Λ$ loop, which is located around 4628 MeV, is found the most likely to cause observable effects. One needs $S$- and $P$-waves in $χ_{c1} Λ$ and $J/ψΛ$ systems, respectively, when the quantum numbers of these systems are $1/2^+$ or $3/2^+$. When the quantum numbers of the $Ξ(2120)$ are $J^P=1/2^+$, $1/2^-$ or $3/2^+$, the peak structure should be sharper than the other $J^P$ choices. This suggests that although the whole strength is unknown, we should pay attention to the contributions from the $Ξ^*$-charmonium-$Λ$ triangle diagram if structures are observed in the $J/ψΛ$ invariant mass spectrum experimentally. In addition, a few triangle diagrams with the $D_{s1}^*(2700)$ as one of the intermediate particles can also produce singularities in the $J/ψΛ$ distribution, but at higher energies above 4.9 GeV.

description: Organosulfur compounds at the interface to noble metals have proved over the last decades to be extremely versatile systems for both fundamental and applied research. However, the anchoring of thiols to gold remained an object of controversy for long times. The RS-Au-SR linkage, in particular, is a robust bonding configuration that displays interesting properties. It is generated spontaneously at room temperature and can be used for the production of extended molecular nanostructures. In this work we explore the behavior of 1,4-Bis(4-mercaptophenyl)benzene (BMB) on the Au(111) surface, which results in the formation of 2D crystalline metal-organic assemblies stabilized by this type of Au-thiolate bonds. We show how to control the thiolates stereospecific bonding motif and thereby choose whether to form ordered arrays of Au3BMB3 units with embedded triangular nanopores, or linearly stacked metal-organic chains. The former turn out to be the thermodynamically favored structures and display confinement of the underneath Au(111) surface state. The electronic properties of single molecules as well as of the 2D crystalline self-assemblies have been characterized both on the metal-organic backbone and inside the associated pores.

description: Dans le cadre des politiques visant à atténuer les émissions de gaz à effets de serre, la France s’appuie aujourd’hui largement sur la substitution énergétique. Cela se traduit par la mise en place de plans d’aide à la mobilisation de bois-énergie ou à la production de chaleur issue de biomasse. En revanche, l’action de l’Etat ne repose pas, à ce jour, sur des mesures privilégiant la séquestration du carbone en forêt du fait de la prise en compte très partielle de la séquestration in situ dans les politiques climatiques internationales découlant du Protocole de Kyoto. Des chercheurs du laboratoire d’économie forestière de Nancy ont développé le French Forest Sector Model (FFSM), un modèle bioéconomique de la filière forêt-bois française, utilisé pour des simulations de politiques climatiques et l’analyse de leurs impacts. Les premiers résultats du modèle FFSM montrent que : (i) une politique ambitieuse de substitution peut être à l’origine de tensions sur la ressource et sur les marchés du bois d’industrie ; (ii) une politique de séquestration présente un meilleur bilan carbone à l’horizon 2020 qu’une politique de substitution; (iii) la mise en place d’une taxe carbone généralisée aurait un effet globalement positif sur la filière forêt-bois française.

description: Two sets of four 3x3 matrices 1^(3), varphi_1, varphi_2, varphi_3 and 1^(3), mu_1, mu_2, mu_3 are constructed, forming two unitarily isomorphic reducible representations 3 of the group Z_2 x Z_2 called often the four-group. They are related to each other through the effective neutrino mixing matrix U with s_{13} = 0, and generate four discrete transformations of flavor and mass active neutrinos, respectively. If and only if s_{13} = 0, the generic form of effective neutrino mass matrix M becomes invariant under the subgroup Z_2 of Z_2 x Z_2 represented by the matrices 1^(3) and varphi_3. In the approximation of m_1 = m_2, the matrix M becomes invariant under the whole Z_2 x Z_2 represented by the matrices 1^(3), varphi_1, varphi_2, varphi_3.

description: The motion of a forced vibro-impacting inclined energy harvester is investigated in parameter regimes with asymmetry in the number of impacts on the bottom and top of the device. This motion occurs beyond a grazing bifurcation, at which alternating top and bottom impacts are supplemented by a zero velocity impact with the bottom of the device. For periodic forcing, we obtain semi-analytical expressions for the asymmetric periodic motion with a ratio of 2:1 for the impacts on the device bottom and top, respectively. These expressions are derived via a set of nonlinear maps between different pairs of impacts, combined with impact conditions that provide jump discontinuities in the velocity. Bifurcation diagrams for the analytical solutions are complemented by a linear stability analysis around the 2:1 asymmetric periodic solutions, and are validated numerically. For smaller incline angles, a second grazing bifurcation is numerically detected, leading to a 3:1 asymmetry. For larger incline angles, period doubling bifurcations precede this bifurcation. The converted electrical energy per impact is reduced for the asymmetric motions, and therefore less desirable under this metric.

description: It is a significant challenge to be successful farming in Canada today. In an ever-changing and increasingly competitive global environment, the Canadian agricultural industry faces the impacts of international competition and trade negotiations, evolving regulations, climate change, shifting consumer demographics and trends, rapidly evolving technology, competition for qualified human resources, and environmental concerns, to name but a few challenges. Much of the solution to deal with these intensifying realities lies in applying proven business approaches and methodologies, coupled with emerging innovative business thinking. Indeed, producers require the appropriate resources and tools to capture opportunity – to anticipate, respond to, and plan for change. However, it is not enough to have the facts and figures; rather, appropriate delivery mechanisms for these resources become equally essential to making the information transferrable and more importantly, applicable. Effective communication of proven business practices with tangible benefits will motivate the sector and empower managers to reach for new heights. This paper focuses on the ever-increasing importance of farm business management – communicating best practices to secure a sustainable and profitable future for Canadian farmers and agriculture at large, using online technology as a means to increase reach and impact, whilst complementing traditional means of information dissemination. The paper seeks to prove delivery is essential to and can greatly enhance content. Specifically, the Agriwebinar™ system exemplifies the importance and benefits of using communication technology to disseminate and encourage farm business management best practices. Agriwebinar™ provides an electronic platform to conduct online seminars on diverse topics to an international audience, and is achieving great success. It is a communication platform that can be used and adopted by other countries for information dissemination and industry collaboration.

description: The objective of this research was to identify the variables that influence on organic food consumption. A survey was given to a non-probabilistic sample of 425 consumers in Talca and Curicó cities, Region of Maule. A binary logistic regression was performed to identify the main variables to the population. The results show that organic foods knowledge; health life style; to know organic agriculture benefits and family income are the most important variables (p < 0,05). This information is relevant for the value chain actors to develop the domestic market on the Region of Maule.

description: Neurotensin (NT) exerts naloxone-insensitive antinociceptive action through its binding to both NTS1 and NTS2 receptors and NT analogs provide stronger pain relief than morphine on a molecular basis. Here, we examined the analgesic/adverse effect profile of a new NT(8-13) derivative denoted JMV2009, in which the Pro10 residue was substituted by a silicon-containing unnatural amino acid silaproline. We first report the synthesis and in vitro characterization (receptor-binding affinity, functional activity and stability) of JMV2009. We next examined its analgesic activity in a battery of acute, tonic and chronic pain models. We finally evaluated its ability to induce adverse effects associated with chronic opioid use, such as constipation and analgesic tolerance or related to NTS1 activation, like hypothermia. In in vitro assays, JMV2009 exhibited high binding affinity for both NTS1 and NTS2, improved proteolytic resistance as well as agonistic activities similar to NT, inducing sustained activation of p42/p44 MAPK and receptor internalization. Intrathecal injection of JMV2009 produced dose-dependent antinociceptive responses in the tail-flick test and almost completely abolished the nociceptive-related behaviors induced by chemical somatic and visceral noxious stimuli. Likewise, increasing doses of JMV2009 significantly reduced tactile allodynia and weight bearing deficits in nerve-injured rats. Importantly, chronic agonist treatment did not result in the development of analgesic tolerance. Furthermore, JMV2009 did not cause constipation and was ineffective in inducing hypothermia. These findings suggest that NT drugs can act as an effective opioid-free medication for the management of pain or can serve as adjuvant analgesics to reduce the opioid adverse effects.

Ultrafast Demagnetization through Femtosecond Generation of Non-thermal Magnons

description: Ultrafast laser excitation of ferromagnetic metals gives rise to correlated, highly non-equilibrium dynamics of electrons, spins and lattice, which are, however, poorly described by the widely-used three-temperature model (3TM). Here, we develop a fully ab-initio parameterized out-of-equilibrium theory based on a quantum kinetic approach--termed (N+2) temperature model--that describes magnon occupation dynamics due to electron-magnon scattering. We apply this model to perform quantitative simulations on the ultrafast, laser-induced generation of magnons in iron and demonstrate that on these timescales the magnon distribution is non-thermal: predominantly high-energy magnons are created, while the magnon occupation close to the center of the Brillouin zone even decreases, due to a repopulation towards higher energy states via a so-far-overlooked scattering term. We demonstrate that the simple relation between magnetization and temperature computed at equilibrium does not hold in the ultrafast regime and that the 3TM greatly overestimates the demagnetization. The ensuing Gilbert damping becomes strongly magnon wavevector dependent and requires a description beyond the conventional Landau-Lifshitz-Gilbert spin dynamics. Our ab-initio-parameterized calculations show that ultrafast generation of non-thermal magnons provides a sizable demagnetization within 200fs in excellent comparison with experimentally observed laser-induced demagnetizations. Our investigation emphasizes the importance of non-thermal magnon excitations for the ultrafast demagnetization process.

description: Besides the ecological advantages, the Photovoltaic plays a very important role in the daylight provision. Although the capacity of collecting energy for the use in buildings is increasing, the visual performance of the technology seems not to have the same importance. In this work the photovoltaic technologies available will be examined and evaluated in terms of both visual and ecological performance. The materials, the installation methods and the energy conversion capacity together with the efficiency and daylight calculation will demonstrate the potential of the organic solar cells. The market counts now three main technologies and, for their bad efficiency, Organic PVs are not considered a good choice. Their potential will be analyzed by evaluating a sample office building with integrated photovoltaic systems in order to see the different visual behavior of the technologies and to prove the good performance of OPVs, which will make them the best choice in the building sector´s future. Two main simulations will be conducted: a thermal evaluation for the energy production and its capacity to help the building energy consumption beside a more important visual evaluation of one office room. The aim is to compute performance indicators that define the inside visual comfort and to analyze their results to see the behavior of a layer of OPVs integrated into windows. The expectation is to demonstrate that this integration will not deny the visual comfort that daylight gives and together will provide electrical energy.
