Sistemas de Reputação baseados em Ledger para ambientes IoT
Creators: name: Oliveira Carneiro, Elisangela
Publisher: name: Zenodo
Year: 2023

description: Os dispositivos participantes dos ecossistemas IoT precisam interagir e cooperar para executar suas funções de sensoriamento, inteligência e atuação em tempo real. Torna-se difícil a escolha de parceiros confiáveis quando os dispositivos interagem com entidades sem referências de confiabilidade. Neste contexto, os modelos de confiança baseados em reputação proporcionam a realização de serviços e cooperação entre entidades confiáveis, contribuindo para melhoria da segurança em IoT. Como os sistemas de reputação também são passíveis de ameaças e ataques, as tecnologias de fog-edge computing e ledger distribuído emergem como soluções descentralizadas para promover segurança e privacidade em IoT. No entanto, integrar estas tecnologias para promover e gerenciar confiança através de reputação requer uma análise criteriosa dos aspectos técnicos usados na solução, devido às características dos dispositivos que fazem parte destes sistemas. A pesquisa encontra-se em fase de especificação do modelo de gerenciamento de confiança a ser implementado nos experimentos.

description: The mechanism of destruction of a central transport barrier in a dynamical model of a geophysical zonal jet current in the ocean or the atmosphere with two propagating Rossby waves is studied. We develop a method for computing a central invariant curve which is an indicator of existence of the barrier. Breakdown of this curve under a variation of the Rossby wave amplitudes and onset of chaotic cross-jet transport happen due to specific resonances producing stochastic layers in the central jet. The main result is that there are resonances breaking the transport barrier at unexpectedly small values of the amplitudes that may have serious impact on mixing and transport in the ocean and the atmosphere. The effect can be found in laboratory experiments with azimuthal jets and Rossby waves in rotating tanks under specific values of the wave numbers that are predicted in the theory.

Critical endpoint for deconfinement in matrix and other effective models

description: We consider the position of the deconfining critical endpoint, where the first order transition for deconfinement is washed out by the presence of massive, dynamical quarks. We use an effective matrix model, employed previously to analyze the transition in the pure glue theory. If the param- eters of the pure glue theory are unaffected by the presence of dynamical quarks, and if the quarks only contribute perturbatively, then for three colors and three degenerate quark flavors this quark mass is very heavy, m_de \sim 2.5 GeV, while the critical temperature, T_de, barely changes, \sim 1% below that in the pure glue theory. The location of the deconfining critical endpoint is a sensitive test to differentiate between effective models. For example, models with a logarithmic potential for the Polyakov loop give much smaller values of the quark mass, m_de \sim 1 GeV, and a large shift in T_de \sim 10% lower than that in the pure glue theory.

Magnetic and density spikes in cosmic ray shock precursors

description: In shock precursors populated by accelerated cosmic rays (CR), the CR return current instability is believed to significantly enhance the pre-shock perturbations of magnetic field. We have obtained fully-nonlinear exact ideal MHD solutions supported by the CR return current. The solutions occur as localized spikes of circularly polarized Alfven envelopes (solitons, or breathers). As the conventional (undriven) solitons, the obtained magnetic spikes propagate at a speed $C$ proportional to their amplitude, $C=C_{A}B_{\rm max}/\sqrt{2}B_{0}$. The sufficiently strong solitons run thus ahead of the main shock and stand in the precursor, being supported by the return current. This property of the nonlinear solutions is strikingly different from the linear theory that predicts non-propagating (that is, convected downstream) circularly polarized waves. The nonlinear solutions may come either in isolated pulses (solitons) or in soliton-trains (cnoidal waves). The morphological similarity of such quasi-periodic soliton chains with recently observed X-ray stripes in Tycho supernova remnant (SNR) is briefly discussed. The magnetic field amplification determined by the suggested saturation process is obtained as a function of decreasing SNR blast wave velocity during its evolution from the ejecta-dominated to the Sedov-Taylor stage.

description: Driven exercise is a transdiagnostic maladaptive behavior, especially common in eating disorders (EDs); however, its maintenance mechanisms remain poorly understood. To address this gap, we examined the applicability of previously empirically derived and validated reinforcement-function models in explaining driven-exercise maintenance in studies varying across developmental stages and clinical presentations (Study 1: N = 279 adolescents/adults oversampled for EDs; Study 2: N = 118 adolescent/adult inpatients with severe EDs; Study 3: N = 52 adults oversampled for athletes and/or EDs). Results supported the utility of a four-function model (automatic positive reinforcement [APR]/automatic negative reinforcement [ANR; increase positive/decrease negative affect], social positive reinforcement [SPR]/social negative reinforcement [SNR; engage in/avoid interpersonal situations]) in explaining driven exercise. APR was most frequently endorsed, followed by ANR, SNR, and SPR in all studies. APR correlated with last-month driven-exercise episodes across studies; associations between other functions and ED psychopathology varied between studies. Furthermore, results suggested a separate control function could be considered in samples with more severe EDs.

Research Data Management

description: The necessity and potential of systematic archiving and publication of digital research data is currently a hot topic in the scientific landscape, due to various benefits such as ensuring reproducibility of research results and providing the basis for data-driven science. This requires measures to ensure data quality and particularly a documentation of stored data by means of metadata, which is understandable to both humans and machines. Machine-actionable metadata is not only important for findability and interoperability of the data but also enables automated data processing. This contribution introduces a workflow for data and metadata, which uses programmatic data aggregation, electronic lab notebooks, ontology-based metadata, and blockchain protocols for partly automated processing and documentation of raw data as well as quality assured data publication, respectively. The practical relevance of the suggested (meta)data workflow is demonstrated at the example of highly resolved current measurements for pulsed dielectric barrier discharges in a nitrogen-oxygen gas mixture.

description: With the help of radial basis function (RBF) and the Garvey-Kelson relation, the accuracy and predictive power of some global nuclear mass models are significantly improved. The rms deviation between predictions from four models and 2149 known masses falls to about 200 keV. The AME95-03 and AME03-Border tests show that the RBF approach is a very useful tool for further improving the reliability of mass models. Simultaneously, the differences from different model predictions for unknown masses are remarkably reduced and the isospin symmetry is better represented when the RBF extrapolation is combined.

Regional and multilateral trade liberalization: Considering next steps: Workshop proceedings, March 16, 2001

description: This distinguished group has gathered at Columbia University to
examine regional trade arrangements under negotiation and in place
and to consider their potential impact on the multilateral system and the
next round of multilateral trade negotiations. The apparent tension
between regional and multilateral trade liberalizing initiatives has a long
history. The first “NAFTA,”  for example, was a proposal nearly 40 years
ago to establish some kind of North Atlantic free trade arrangement
because multilateral negotiations appeared to some to be running out of
steam. This notion that regional arrangements can supplement or even
spur multilateral negotiations remains with us today. This workshop
examines a number of new developments that warrant serious consideration and serve as the context for this gathering.

description: This paper mainly presents how the author organizes the class "Chinese film", a course for advanced students at Freie Universitat Berlin. The aim of such classes is to give students an opportunity to understand current Chinese society better and to discuss current issues they are interested in in their target language, Chinese. Furthermore, by watching films and following their protagonists through the story, students are confronted with Chinese cultural values and Chinese people's value choices as well as dilemmas the Chinese protagonists find themselves in. This puts the students into an intercultural learning situation which is enhanced by the fact that their teacher is also Chinese, albeit somewhat competent in regard to their culture. Thus, Chinese made films may also be employed to strengthen intercultural understanding and intercultural skills, because while the protagonists cannot debate with their German audience of Sinology students, their Chinese bom teacher can.

We first prove that the pancake graph, denoted by $P_n (n\geq 4),$ is super-connected and hyper-connected. Further, we study the symmetry of $P_n$ and completely determine its full automorphism group,which shows that $P_n (n\geq 5)$ is a graphical regular representation of $S_n.$

Intellectual property

description: Technological progress and increased globalization have raised the importance of intellectual property rights (IPR) issues. As countries at the technological frontier, the United States and Japan have risen to the forefront of building a framework for IPR systems and international negotiations. To what degree and in what way have the U.S. and Japanese IPR systems converged? What are the economic, business and political implications? How do business method patents fit into this global strategy? Do we need to rethink whether a global approach to IPR works in developing countries? How can the U.S. and Japan support the implementation of IPR commitments that China has made? On February 15, 2002, these and related issues were discussed at a major public policy conference which was hosted by the Center on Japanese Economy and Business and the Center for Japanese Legal Studies of Columbia University. Presentations were made by a select group of distinguished business professionals, lawyers and academics. Mr. Robert Stoll, Administrator, Office of Legislative and International Affairs, United States Department of Commerce Patent and Trade Office, was the luncheon speaker . Excerpts of the speakers' presentations and discussion between the panelists and audience are presented in the following pages.

description: We discuss how to systematically compute the asymptotic symmetry algebras of generic three-dimensional bosonic higher-spin gauge theories in backgrounds that are asymptotically AdS. We apply these techniques to a one-parameter family of higher-spin gauge theories that can be considered as large N limits of SL(N) x SL(N) Chern-Simons theories, and we provide a closed formula for the structure constants of the resulting infinite-dimensional non-linear W-algebras. Along the way we provide a closed formula for the structure constants of all classical W_N algebras. In both examples the higher-spin generators of the W-algebras are Virasoro primaries. We eventually discuss how to relate our basis to a non-primary quadratic basis that was previously discussed in literature.

description: We present a detailed analysis of the neutral hydrogen kinematics of 12 nearby dwarf irregular galaxies observed as part of the Local Volume HI Survey (LVHIS) conducted at the Australia Telescope Compact Array. For each galaxy we measure the disk parameters (inclination, position angle) and the HI rotation curve. Six galaxies in our sample (AM0605-341, Argo Dwarf, ESO059-G001, ESO137-G018, ESO174-G?001, ESO308-G022) have their atomic hydrogen distribution studied for the first time. AM0605-341 was found to have an extension of redshifted HI which we propose is due to a tidal interaction with NGC2188. There is evidence that ESO215-G?009 has extraplanar HI gas. We also compare the global galaxy properties, in particular the integrated HI flux density and velocity widths of the observed HI spectra with the results from the low angular resolution HI Parkes All Sky Survey (HIPASS). We discuss under what circumstances the 21cm emission line profile can accurately predict the galaxy's rotation velocity, an observational parameter crucial to study the classical and baryonic Tully-Fisher relations.

This phenomena has been explained by incorporating a deviation parameter ($ε$) to the surface barrier term ($E_D$) in the kinematic Monte Carlo (kMC) simulations as one of the plausible mechanisms.

description: [NiFe] hydrogenases are complex model enzymes for the reversible cleavage of dihydrogen (H2). However, structural determinants of efficient H2 binding to their [NiFe] active site are not properly understood. Here, we present crystallographic and vibrational‐spectroscopic insights into the unexplored structure of the H2‐binding [NiFe] intermediate. Using an F420‐reducing [NiFe]‐hydrogenase from Methanosarcina barkeri as a model enzyme, we show that the protein backbone provides a strained chelating scaffold that tunes the [NiFe] active site for efficient H2 binding and conversion. The protein matrix also directs H2 diffusion to the [NiFe] site via two gas channels and allows the distribution of electrons between functional protomers through a subunit‐bridging FeS cluster. Our findings emphasize the relevance of an atypical Ni coordination, thereby providing a blueprint for the design of bio‐inspired H2‐conversion catalysts.

description: We report on infrared (IR) absorption and dc electrical measurements of thin films of poly(3-hexylthiophene) (P3HT) that have been modified by a fluoroalkyl trichlorosilane (FTS). Spectra for FTS-treated films were compared to data for electrostatically-doped P3HT in an organic field-effect transistor (OFET). The appearance of a prominent polaron band in mid-IR absorption data for FTS-treated P3HT supports the assertion of hole doping via a charge-transfer process between FTS molecules and P3HT. In highly-doped films with a significantly enhanced polaron band, we find a monotonic Drude-like absorption in the far-IR, signifying delocalized states. Utilizing a simple capacitor model of an OFET, we extracted a carrier density for FTS-treated P3HT from the spectroscopic data. With carrier densities reaching 10$^{14}$ holes/cm$^2$, our results demonstrate that FTS doping provides a unique way to study the metal-insulator transition in polythiophenes.

description: Machine-learning force fields (MLFF) should be accurate, computationally and data efficient, and applicable to molecules, materials, and interfaces thereof. Currently, MLFFs often introduce tradeoffs that restrict their practical applicability to small subsets of chemical space or require exhaustive datasets for training. Here, we introduce the Bravais-Inspired Gradient-Domain Machine Learning (BIGDML) approach and demonstrate its ability to construct reliable force fields using a training set with just 10–200 geometries for materials including pristine and defect-containing 2D and 3D semiconductors and metals, as well as chemisorbed and physisorbed atomic and molecular adsorbates on surfaces. The BIGDML model employs the full relevant symmetry group for a given material, does not assume artificial atom types or localization of atomic interactions and exhibits high data efficiency and state-of-the-art energy accuracies (errors substantially below 1 meV per atom) for an extended set of materials. Extensive path-integral molecular dynamics carried out with BIGDML models demonstrate the counterintuitive localization of benzene–graphene dynamics induced by nuclear quantum effects and their strong contributions to the hydrogen diffusion coefficient in a Pd crystal for a wide range of temperatures.

description: The SAGE-LMC, SAGE-SMC and HERITAGE surveys have mapped the Magellanic Clouds in the infrared using the Spitzer and Herschel Space Telescopes. Over 8.5 million point sources were detected and catalogued in the LMC alone. Staring mode observations using the InfraRed Spectrograph (IRS) on board Spitzer have been obtained for 1,000 positions in the LMC and ~250 in the SMC. From the infrared spectroscopy we have identified the nature of the sources for which spectroscopy is available. These IRS staring mode targets represent an important contribution to the SED of these dwarf galaxies. Here we report on our latest results.

description: "Aimed specifically at Western businesses and managers, this book offers a general framework for understanding Chinese business culture." "You are given practical advice throughout on business etiquette, and how to incorporate Chinese expectations to achieve your goals." These are common samples of advertising texts of German publications which promise to give intercultural advice for German business people who are going on a business trip to China. This paper gives a brief overview of the analysis on the way China is presented in German intercultural advice literature from 1972 to 2008 with a special focus on 2004 to 2008. It contains the first comprehensive list of intercultural advice books on the German book market from 1972 to 2008 and outlines a number of criteria for a first sound classification and evaluation of those publications.

description: The precipitation microstructure of the γ' (AlAg2) intermetallic phase has been examined in aluminium-silver-copper alloys. The microstructure developed in an Al-0.90at.%Ag-0.90at.%Cu alloy was significantly different from that reported for binary Al-Ag alloys. The orientation relationship between the matrix and precipitate was unchanged; however, the γ' phase formed as aggregates with a two-dimensional open assemblies. Each such assembly contained two variants of the γ' phase alternately arranged to form a faceted elliptical unit. The θ' (Al2Cu) phase formed on these assemblies after further ageing. The faceted elliptical assembly morphology has not been previously reported for the γ' precipitate. The change in precipitation behaviour was attributed to copper modifying the as-quenched defect structure of the matrix. This precipitation morphology clarifies earlier observations on the precipitate number density and mechanical properties of aluminium-silver-copper alloys.

The star catalogues of Ptolemaios and Ulugh Beg: Machine-readable versions and comparison with the modern Hipparcos Catalogue

description: In late antiquity and throughout the middle ages, the positions of stars on the celestial sphere were obtained from the star catalogue of Ptolemaios. A catalogue based on new measurements appeared in 1437, with positions by Ulugh Beg, and magnitudes from the 10th-century astronomer al-Sufi. We provide machine-readable versions of these two star catalogues, based on the editions by Toomer (1998) and Knobel (1917), and determine their accuracies by comparison with the modern Hipparcos Catalogue. The magnitudes in the catalogues correlate well with modern visual magnitudes; the indication `faint' by Ptolemaios is found to correspond to his magnitudes 5 and 6. Gaussian fits to the error distributions in longitude / latitude give widths sigma ~ 27 arcmin / 23 arcmin in the range |Delta lambda, Delta beta|<50 arcmin for Ptolemaios and sigma ~ 22 arcmin /18 arcmin in Ulugh Beg. Fits to the range |Delta lambda, Delta beta|<100 arcmin gives 10-15 per cent larger widths, showing that the error distributions are broader than gaussians. The fraction of stars with positions wrong by more than 150 arcmin is about 2 per cent for Ptolemaios and 0.1 per cent in Ulugh Beg; the numbers of unidentified stars are 1 in Ptolemaios and 3 in Ulugh Beg. These numbers testify to the excellent quality of both star catalogues (as edited by Toomer and Knobel).

description: The formalism to compute the geometrical and topological one-point statistics of mildly non-Gaussian 2D and 3D cosmological fields is developed. Leveraging the isotropy of the target statistics, the Gram-Charlier expansion is reformulated with rotation invariant variables. This formulation allows us to track the geometrical statistics of the cosmic field to all orders. It then allows us to connect the one point statistics of the critical sets to the growth factor through perturbation theory, which predicts the redshift evolution of higher order cumulants. In particular, the cosmic non-linear evolution of the skeleton's length, together with the statistics of extrema and Euler characteristic are investigated in turn. In 2D, the corresponding differential densities are analytic as a function of the excursion set threshold and the shape parameter. In 3D, the Euler characteristics and the field isosurface area are also analytic to all orders in the expansion. Numerical integrations are performed and simple fits are provided whenever closed form expressions are not available. These statistics are compared to estimates from N-body simulations and are shown to match well the cosmic evolution up to root mean square of the density field of ~0.2. In 3D, gravitational perturbation theory is implemented to predict the cosmic evolution of all the relevant Gram-Charlier coefficients for universes with scale invariant matter distribution. The one point statistics of critical sets could be used to constrain primordial non-Gaussianities and the dark energy equation of state on upcoming cosmic surveys; this is illustrated on idealized experiments.

description: 本文探討量詞「口」在大陸和台灣兩岸地區使用的異同。量詞「口」，用於計量非生物名詞時，在兩岸法中，有很高的一致性。「口」在台灣和大陸的不同用法，主要表現在計量人和動物兩方面。大陸地區用「口」來計量家庭或團體單位（如「家」、「村」、「里」、「厰」）的總人數，可有「數詞+口+人」的形式。台灣至今仍保留「一/全+家/戶/村+數詞+口」 、「數詞+口+之家」的固定格式，表達總人口數，而「口」後不接名詞「人」。計量部分的家庭成員時，兩岸用法相同，皆用「個」，不用「口」。「口」 在大陸用法中，還可見用於計量「豬」等動物，但自古以來量詞的發展，有一趨勢，即「口」計量動物的用法，逐漸由「隻」來取代。華語教材的編輯，以及華語文的測驗與評量試題，應該考慮兩岸詞彙的差異，審慎考量教材與試題的適用範圍。

description:  Chirality in Sixta Theory is not a byproduct but a primary selector of reality. It governs allowable twist-phase paths, filters observer resonance, and causes dimensional asymmetry. This paper shows how chirality directly shapes the physics each observer experiences and determines the structural composition of reality through harmonic filtration.
Mass effect and coherence in medium-induced QCD radiation off a $q {\bar q}$ antenna

description: The medium-induced one-gluon radiation spectrum off a massive quark-antiquark ($q {\bar q}$) antenna traversing a colored QCD medium is calculated in this contribution. The gluon spectrum off the antenna computed at first order in the opacity expansion is collinear finite but infrared divergent, which is different from the result obtained from an independent emitter which is both infrared and collinear finite. The interference between emitters dominates the soft gluon radiation when the antenna opening angle is small and the emitted gluon is soft, whereas the antenna behaves like a superposition of independent emitters when the opening angle is large and the radiated gluon is hard. As a phenomenological consequence, we investigate the energy lost by the projectiles due to the radiation. In general, the size of the mass effects is similar in both cases.

Teaching advanced spoken Chinese. Integration of accuracy and cultural awareness in word choice
Creators: name: WU, Ching-Hsuan
Publisher: name: CHUN - Chinesischunterricht
Year: 2022

description: Advanced Chinese learners, in general, are able to verbally express themselves and communicate with others on a variety of topics. In addition, they usually possess knowledge, to a certain extent, with respect to Chinese culture, such as history, cultural practice, and art. With such speaking skills and knowledge in Chinese language and culture, advanced Chinese speakers are not often concerned with getting meaning across. However, they can find it challenging to be precise in word choice, including both structural patterns and vocabulary. As a result of being imprecise, not necessarily being wrong, utterances of advanced Chinese learners can be grammatically correct but idiomatically or culturally inappropriate. Indiscriminate use of words is not uncommon and in most cases not predictable as the range of conversation topics among advanced Chinese learners is widened rapidly as they progress daily. Therefore, the emphasis of pedagogical teaching approaches to treat this type of intricate problem needs to be placed not only on the introduction of linguistic properties of certain vocabulary or structures, but, more importantly, on effective allocation of second language learners' attentional resources towards how native speakers of Chinese perform pragmatically. In the paper, a collection of common mistakes regarding word choice made by advanced Chinese speakers is presented. Following the discussions on these mistakes, pedagogical tasks are introduced which can be utilized in Chinese classrooms to promote grammatically correct and culturally appropriate speech.

Electron positron pairs in blazar jets and gamma-ray loud radio-galaxies

description: The matter content of extragalactic relativistic jets is still an unsolved issue. There are strong arguments against pure electron-positron pair jets, but pairs could outnumber the electrons associated with protons by a factor 10-20. This impacts on the estimate of the jet kinetic power, by reducing it by the same factor, and on the total energy delivered to leptons by the particle acceleration mechanism. Pairs cannot be created in the same jet-zone responsible for the high energy gamma-ray emission we see in blazars, because the reprocessing of the created pairs would overproduce the X-ray flux. Copious pair creation could occur in the inner zone of the still accelerating jet, where the bulk Lorentz factor is small. It is found that the inner zone can produce a sufficient number of pairs to replenish the zone of the jet where most of the luminosity is emitted, but only if the gamma-ray luminosity of the inner jet is above 1e44 erg/s at ~1 MeV. Since the beaming is modest, this emission can be observed at large viewing angles, and detected in radio-galaxies and lobe dominated quasars at the flux level of 1e-12 - 1e-11 erg/cm2/s for a source at a redshift z=0.1.
