Evaluating Task Acceptance in Crowdsourcing for Crisis Communication
Creators: name: Pestana, Maria Clara

Publisher: name: Zenodo
Year: 2022

description: Crowdsourcing is a technique that uses data from the crowd to solve a more significant problem. This technique can be applied to support crisis communication, allowing the civil population to collaborate with public emergency response institutions, by accepting to voluntarily engage in the requested tasks. They can provide relevant data that would be useful for crisis professionals. Scientifical analyses show implications in the functioning of crowdsourcing systems that can affect the experience of using crisis volunteers platforms, overload of notifications or complex tasks can result in problems of motivation and engagement, consequently decreasing the quality of task results. This research project aims to evaluate task acceptance in crowdsourcing platforms for crisis communication support, analyze the use of context-aware computing to target users potentially engaged in collaborative tasks, and analyze the use of contextual data to be used as relevant information for communication with crisis agencies. The project proposes to develop a case study experiment, simulating scenarios where citizens can be benefited when volunteering in a context-aware platform for crisis communication domain. The experiment uses different treatments to contrast the task design of platforms and the acceptance rate.
From dlogs to dilogs; the super Yang-Mills MHV amplitude revisited

description: Recently, loop integrands for certain Yang-Mills scattering amplitudes and correlation functions have been shown to be systematically expressible in dlog form, raising the possibility that these loop integrals can be performed directly without Feynman parameters. We do so here to give a new description of the planar 1-loop MHV amplitude in N = 4 super Yang-Mills theory. We explicitly incorporate the standard Feynman i epsilon prescription into the integrands. We find that the generic MHV diagram contributing to the 1-loop MHV amplitude, known as Kermit, is dual conformal invariant up to the choice of reference twistor explicit in our axial gauge (the generic MHV diagram was already known to be finite). The new formulae for the amplitude are nontrivially related to previous ones in the literature. The divergent diagrams are evaluated using mass regularization. Our techniques extend directly to higher loop diagrams, and we illustrate this by sketching the evaluation of a non-trivial 2-loop example. We expect this to lead to a simple and efficient method for computing amplitudes and correlation functions with less supersymmetry and without the assumption of planarity.

Meeting the challenges of English-medium higher education: The first-year experience in Hong Kong. English for Specific Purposes, 30(3), 198-208. https://doi.org/10.1016/j.esp.2011.01.001). The scale can be used in its entirety to capture challenges across all four skills, or researchers may wish to only use the items associated with each of the four skills (writing, reading, speaking, or listening). Research has shown each academic skill to constitute its own factor, and each factor to have very high reliability. Mean scores for each of the four skills can, therefore, be used for analysis in research.
Homogeneous cosmologies as group field theory condensates

description: We give a general procedure, in the group field theory (GFT) formalism for quantum gravity, for constructing states that describe macroscopic, spatially homogeneous universes. These states are close to coherent (condensate) states used in the description of Bose-Einstein condensates. The condition on such states to be (approximate) solutions to the quantum equations of motion of GFT is used to extract an effective dynamics for homogeneous cosmologies directly from the underlying quantum theory. The resulting description in general gives nonlinear and nonlocal equations for the 'condensate wavefunction' which are analogous to the Gross-Pitaevskii equation in Bose-Einstein condensates. We show the general form of the effective equations for current quantum gravity models, as well as some concrete examples. We identify conditions under which the dynamics becomes linear, admitting an interpretation as a quantum-cosmological Wheeler-DeWitt equation, and give its semiclassical (WKB) approximation in the case of a kinetic term that includes a Laplace-Beltrami operator. For isotropic states, this approximation reproduces the classical Friedmann equation in vacuum with positive spatial curvature. We show how the formalism can be consistently extended from Riemannian signature to Lorentzian signature models, and discuss the addition of matter fields, obtaining the correct coupling of a massless scalar in the Friedmann equation from the most natural extension of the GFT action. We also outline the procedure for extending our condensate states to include cosmological perturbations. Our results form the basis of a general programme for extracting effective cosmological dynamics directly from a microscopic non-perturbative theory of quantum gravity.

description: We develop a theoretical framework for the study of epidemic-like social contagion in large scale social systems. We consider the most general setting in which different communication platforms or categories form multiplex networks. Specifically, we propose a contact-based information spreading model, and show that the critical point of the multiplex system associated to the active phase is determined by the layer whose contact probability matrix has the largest eigenvalue. The framework is applied to a number of different situations, including a real multiplex system. Finally, we also show that when the system through which information is disseminating is inherently multiplex, working with the graph that results from the aggregation of the different layers is flawed.

description: In the sixties Ogievetskii and Polubarinov proposed the concept of a notoph, whose helicity properties are complementary to those of a photon. Later, Kalb and Ramond (and others) developed this theoretical concept. And, at the present times it is widely accepted. We analyze the quantum theory of antisymmetric tensor fields with taking into account mass dimensions of notoph and photon. It appears to be possible to describe both photon and notoph degrees of freedom on the basis of the modified Bargmann-Wigner formalism for the symmetric second-rank spinor. Next, we proceed to derive equations for the symmetric tensor of the second rank on the basis of the Bargmann-Wigner formalism in a straightforward way. The symmetric multispinor of the fourth rank is used. It is constructed out of the Dirac 4-spinors. Due to serious problems with the interpretation of the results obtained on using the standard procedure we generalize it and obtain the spin-2 relativistic equations, which are consistent with the general relativity. The importance of the 4-vector field (and its gauge part) is pointed out. Thus, we present the full theory which contains photon, notoph (the Kalb-Ramond field) and the graviton. The relations of this theory with the higher spin theories are established. In fact, we deduced the gravitational field equations from relativistic quantum mechanics. We estimate possible interactions, fermion-notoph, graviton-notoph, photon-notoph. PACS number: 03.65.Pm, 04.50.-h, 11.30.Cp

description: The concept of technical debt (TD) refers to the problems faced during the software development process, where the process tasks are not performed properly. Both industry and academia have given significant attention to TD research throughout the software development lifecycle. However, we still know little about the motivation surrounding the actions that make stakeholders contract or pay a debt. Value-based software engineering is a research area that emphasizes value thinking in software-related decisions, so we can optimize decision-making at all levels to meet or reconcile the explicit objectives of the stakeholders involved. This work aims to present an approach that focuses on the value propositions that the main stakeholders of a software development process use during the selection and fix of technical debts. From the elaborated theory, We want to propose a approach to support TD management and evaluate it through case studies with academia and industry.

description: A resonant photoacoustic cell capable of detecting the traces of gases at an amplitude-modulation regime is represented. The cell is designed so as to minimize the window background for the cell operation at a selected acoustic resonance. A compact prototype cell (the volume of acoustic cavity of ~ 0.2 cm^3, total cell weight of 3.5 g) adapted to the narrow diffraction-limited beam of near-infrared laser is produced and examined experimentally. The noise-associated measurement error and laser-initiated signals are studied as functions of modulation frequency. The background signal and useful response to light absorption by the gas are analyzed in measurements of absorption for ammonia traces in nitrogen flow with the help of a pigtailed DFB laser diode operated near a wavelength of 1.53 um. The performance of absorption detection and gas-leak sensing for the prototype operated at the second longitudinal acoustic resonance (the resonance frequency of ~ 4.38 kHz, Q-factor of ~ 13.9) is estimated. The noise-equivalent absorption normalized to laser-beam power and detection bandwidth is ~ 1.44x10^{-9} cm^{-1} W Hz^{-1/2}. The amplitude of the window-background signal is equivalent to an absorption coefficient of ~ 2.82x10^{-7} cm^{-1}.

Target detection

description: The unitary matrix pencil (UMP) method has been successfully applied to antenna array optimization. In this work, the UMP method is applied to the parameter estimation of target detection based on the attributed scattering center (ASC) model. This method can accurately estimate the number of arbitrary group targets in the space. Firstly, the radar cross section (RCS) is reconstructed based on the ASC model. Since the unitary matrix can be used to process the parameter estimation of the echo with 'sum of attenuation exponents', the unitary matrix is constructed by the samples from this reconstructed RCS. Moreover, the stronger scattering center can be characterized via the larger singular values, and the number of group targets can be obtained by solving the number of large singular values. Then, singular value decomposition (SVD) is performed on this unitary matrix, and some larger singular values are screened by setting an appropriate threshold. The higher estimation accuracy can be obtained by fusing the echoes from multiple frequencies and angles. Besides, the estimation accuracies of this proposed method in this work are discussed under different signal-to-noise ratios (SNR) considering the noise in the actual scene. Simulation results show that this method can effectively and accurately estimate the number of group targets, and it shows strong robustness. In this data file, the simulation results obtained by commercial software FEKO and MATLAB are listed.

description: We study the spontaneous R-symmetry breaking model and investigate the cosmological constraints on this model due to the pseudo Nambu-Goldstone boson, R-axion. We consider the R-axion which has relatively heavy mass in order to complement our previous work. In this regime, model parameters, R-axions mass and R-symmetry breaking scale, are constrained by Big Bang Nucleosynthesis and overproduction of the gravitino produced from R-axion decay and thermal plasma. We find that the allowed parameter space is very small for high reheating temperature. For low reheating temperature, the U(1)_R breaking scale f_a is constrained as f_a<10^{12-14}GeV regardless of the value of R-axion mass.

description: A Internet das Coisas (IoT) disponibiliza serviços para objetos inteligentes e humanos com uma crescente influência em nossa vida diária. Para isso, os dispositivos IoT precisam de capacidade de detecção, inteligência e atuação em tempo real, que podem ser obtidos através de diversas formas de cooperação. No entanto, é difícil a escolha de parceiros confiáveis, principalmente, quando os dispositivos migram entre diferentes ambientes e interagem com entidades sem referências de confiabilidade. Neste contexto, os modelos de confiança baseados em reputação permitem a realização de serviços e cooperação entre entidades confiáveis, contribuindo para melhoria da segurança e privacidade em IoT. Contudo, os sistemas de reputação também são passíveis de ameaças e ataques. As tecnologias de fog-edge computing e blockchain (BC) estão emergindo como soluções descentralizadas de segurança e privacidade para ambientes IoT. Em contraste, enquanto os dispositivos IoT geram grande quantidades de dados, possuem heterogeneidade e limitação de recursos, a BC tende a ter taxas de transferências limitadas e uso intensivo de recursos. Deste modo, propor um sistema de reputação para IoT que integre estes paradigmas requer uma análise criteriosa dos aspectos tecnológicos a serem utilizados na solução. Atualmente, a pesquisa se encontra em fase de revisão de literatura para identificar como as soluções IoT integram fog-edge e BC e como funcionam os sistemas de reputação IoT baseados em BC.

description: We present a theory describing the trapping and untrapping of quasiparticles in the Andreev bound level of a single-channel weak link between two superconductors. We calculate the rates of the transitions between even and odd occupations of the Andreev level induced by absorption and emission of both photons and phonons. We apply the theory to a recent experiment [Phys. Rev. Lett. 106, 257003 (2011)] in which the dynamics of the trapping of quasiparticles in the Andreev levels of superconducting atomic contacts coupled to a Josephson junction was measured. We show that the plasma energy $hν_p$ of the Josephson junction defines a rather abrupt transition between a fast relaxation regime dominated by coupling to photons and a slow relaxation regime dominated by coupling to phonons. With realistic parameters the theory provides a semi-quantitative description of the experimental results.

description: We compute the next-to-leading order (NLO) QCD corrections to the $1 \to 2$ splitting amplitudes in different dimensional regularization (DREG) schemes. Besides recovering previously known results, we explore new DREG schemes and analyze their consistency by comparing the divergent structure with the expected behavior predicted by Catani's formula. Through the introduction of scalar-gluons, we show the relation among splittings matrices computed using different schemes. Also, we extended this analysis to cover the double collinear limit of scattering amplitudes in the context of QCD+QED.

Bulk Majorana mass terms and Dirac neutrinos in Randall Sundrum Model

Year: 2013

description: We present a novel scheme where Dirac neutrinos are realized even if lepton number violating Majorana mass terms are present. The setup is the Randall-Sundrum framework with bulk right handed neutrinos. Bulk mass terms of both Majorana and Dirac type are considered. It is shown that massless zero mode solutions exist when the bulk Dirac mass term is set to zero. In this limit, it is found that the effective 4D small neutrino mass is primarily of Dirac nature with the Majorana type contributions being negligible. Interestingly, this scenario is very similar to the one known with flat extra dimensions. Neutrino phenomenology is discussed by fitting both charged lepton masses and neutrino masses simultaneously. A single Higgs localised on the IR brane is highly constrained as unnaturally large Yukawa couplings are required to fit charged lepton masses. A simple extension with two Higgs doublets is presented which facilitates a proper fit for the lepton masses.

description: Within the next five years, it is expected that the Advanced LIGO/Virgo network will have reached a sensitivity sufficient to enable the routine detection of gravitational waves. Beyond the initial detection, the scientific promise of these instruments relies on the effectiveness of our physical parameter estimation capabilities. The majority of this effort has been towards the detection and characterization of gravitational waves from compact binary coalescence, e.g. the coalescence of binary neutron stars. While several previous studies have investigated the accuracy of parameter estimation with advanced detectors, the majority have relied on approximation techniques such as the Fisher Matrix. Here we report the statistical uncertainties that will be achievable for optimal detection candidates (SNR = 20) using the full parameter estimation machinery developed by the LIGO/Virgo Collaboration via Markov-Chain Monte Carlo methods. We find the recovery of the individual masses to be fractionally within 9% (15%) at the 68% (95%) credible intervals for equal-mass systems, and within 1.9% (3.7%) for unequal-mass systems. We also find that the Advanced LIGO/Virgo network will constrain the locations of binary neutron star mergers to a median uncertainty of 5.1 deg^2 (13.5 deg^2) on the sky. This region is improved to 2.3 deg^2 (6 deg^2) with the addition of the proposed LIGO India detector to the network. We also report the average uncertainties on the luminosity distances and orbital inclinations of ideal detection candidates that can be achieved by different network configurations.

description: We present the supernova (SN) sample and Type-Ia SN (SN Ia) rates from the Cluster Lensing And Supernova survey with Hubble (CLASH). Using the Advanced Camera for Surveys and the Wide Field Camera 3 on the Hubble Space Telescope (HST), we have imaged 25 galaxy-cluster fields and parallel fields of non-cluster galaxies. We report a sample of 27 SNe discovered in the parallel fields. Of these SNe, ~13 are classified as SN Ia candidates, including four SN Ia candidates at redshifts z > 1.2. We measure volumetric SN Ia rates to redshift 1.8 and add the first upper limit on the SN Ia rate in the range 1.8 < z < 2.4. The results are consistent with the rates measured by the HST/GOODS and Subaru Deep Field SN surveys. We model these results together with previous measurements at z < 1 from the literature. The best-fitting SN Ia delay-time distribution (DTD; the distribution of times that elapse between a short burst of star formation and subsequent SN Ia explosions) is a power law with an index of -1.00 +0.06(0.09) -0.06(0.10) (statistical) +0.12 -0.08 (systematic), where the statistical uncertainty is a result of the 68% and 95% (in parentheses) statistical uncertainties reported for the various SN Ia rates (from this work and from the literature), and the systematic uncertainty reflects the range of possible cosmic star-formation histories. We also test DTD models produced by an assortment of published binary population synthesis (BPS) simulations. The shapes of all BPS double-degenerate DTDs are consistent with the volumetric SN Ia measurements, when the DTD models are scaled up by factors of 3-9. In contrast, all BPS single-degenerate DTDs are ruled out by the measurements at a >99% significance level.

description: In this study a family of local quantities defined on each partition and its averaging on a macroscopic small region, site, are defined on a multibaker chain system. On its averaged quantities, a law of order estimation (LOE) in the bulk system is proved, making it possible to estimate the order of the quantities with respect to the representative partition scale parameter $Δ$. Moreover, the form of the leading-order terms of the averaged quantities is obtained, and the form enables us to have the macroscopic quantity in the continuum limit, as $Δ\rightarrow0$, and to confirm its partitioning independency. These deliverables fully explain the numerical results obtained by Ishida, consistent with the irreversible thermodynamics.

description: The inclusion of Dirac fermions in Einstein-Cartan gravity leads to a four-fermion interaction mediated by non-propagating torsion, which can allow for the formation of a Bardeen-Cooper-Schrieffer condensate. By considering a simplified model in 2+1 spacetime dimensions, we show that even without an excess of fermions over antifermions, the nonthermal distribution arising from preheating after inflation can give rise to a fermion condensate generated by torsion. We derive the effective Lagrangian for the spacetime-dependent pair field describing the condensate in the extreme cases of nonrelativistic and massless fermions, and show that it satisfies the Gross-Pitaevski equation for a gapless, propagating mode.

description: We discuss the construction of Sp(2)Sp(1)-structures whose fundamental form is closed. In particular, we find 10 new examples of 8-dimensional nilmanifolds that admit an invariant closed 4-form with stabiliser Sp(2)Sp(1). Our constructions entail the notion of SO(4)-structures on 7-manifolds. We present a thorough investigation of the intrinsic torsion of such structures, leading to the construction of explicit Lie group examples with invariant intrinsic torsion.

description: We consider the effect of contact interaction in a prototypical quantum spin Hall system of pseudo-spin-1/2 particles. A strong effective magnetic field with opposite directions for the two spin states restricts two-dimensional particle motion to the lowest Landau level. While interaction between same-spin particles leads to incompressible correlated states at fractional filling factors as known from the fractional quantum Hall effect, these states are destabilized by interactions between opposite spin particles. Exact results for two particles with opposite spin reveal a quasi-continuous spectrum of extended states with a large density of states at low energy. This has implications for the prospects of realizing the fractional quantum spin Hall effect in electronic or ultra-cold atom systems. Numerical diagonalization is used to extend the two-particle results to many bosonic particles and trapped systems. The interplay between an external trapping potential and spin-dependent interactions is shown to open up new possibilities for engineering exotic correlated many-particle states with ultra-cold atoms.

description: We detect the peak of baryon acoustic oscillations (BAO) in the two-point correlation function of a spectroscopic sample of $25226$ clusters selected from the Sloan Digital Sky Survey. Galaxy clusters, as tracers of massive dark matter haloes, are highly biased structures. The linear bias $b$ of the sample considered in this work, that we estimate from the projected correlation function, is $b σ_8 = 1.72 \pm 0.03$. Thanks to the high signal in the cluster correlation function and to the accurate spectroscopic redshift measurements, we can clearly detect the BAO peak and determine its position, $s_p$, with high accuracy, despite the relative paucity of the sample. Our measurement, $s_p = 104 \pm 7 \, \mathrm{Mpc} \, h^{-1}$, is in good agreement with previous estimates from large galaxy surveys, and has a similar uncertainty. The BAO measurement presented in this work thus provides a new strong confirmation of the concordance cosmological model and demonstrates the power and promise of galaxy clusters as key probes for cosmological applications based on large scale structures.

description: Direct LHC bounds on colored SUSY particles now corner naturalness more than the measured value of the Higgs mass does. Bounds on the gluino are of particular importance, since it radiatively "sucks" up the stop and Higgs-up soft masses. As a result, even models that easily accommodate a 125 GeV Higgs are almost as tuned as the simplest version of SUSY, the MSSM: at best at the percent level. In this paper, we further examine how current LHC results constrain naturalness in three classes of models that may relax LHC bounds on sparticles: split families, baryonic RPV, and Dirac gauginos. In models of split families and bRPV, the bounds on the gluino are only slightly reduced, resulting in a few percent tuning. In particular, having a natural spectrum in bRPV models typically implies that tops, Ws, and Zs are easily produced in the cascade decays of squarks and gluinos. The resulting leptons and missing energy push the gluino mass limit above 1 TeV. Even when the gluino has a Dirac mass and does not contribute to the stop mass at one loop, tuning reappears in calculable models because there is no symmetry imposing the supersoft limit. We conclude that, even if sparticles are found at LHC-14, naturalness will not emerge triumphant.

Disagreement within contemporary analytic philosophy : a pragmatic perspective

description: In this thesis, I offer a new perspective on the extant disagreement within contemporary analytic philosophy - and, in particular, a perspective which is grounded in both the 2009 and 2020 PhilPapers Surveys of David Bourget and David Chalmers (2014; and forthcoming), as well as a tradition that is often disregarded by contemporary analytic philosophers: Pragmatism. I call it “a pragmatic perspective.” Using that perspective, I work through various aspects of the existing philosophical literatures on disagreement in order to evaluate the discipline’s own. On the one hand, I clarify and extend this literature - especially, as it applies to the discipline. But, several gaps are also found and addressed, including: what pragmatic commitments and policies contemporary analytic philosophers might need to make and enact in order to address their disagreement; how disagreement might affect the possession, transferability, and vindication of various collective epistemic/rational goods (for example, collective knowledge or rational consensus); and what consequences such philosophers might be forced to face - both inside and outside of their discipline - if they are unable to possess, transfer, and vindicate all that many epistemic/rational goods. Overall, my results are more grounded conclusions regarding both the nature and extent of the disagreement within the discipline, as well as a clearer understanding of why contemporary analytic philosophers might be right to worry about it and how they might be able to resolve it.
Mechanism of Ultrafast Relaxation of a Photo-Carrier in Antiferromagnetic Spin Background

description: We study the relaxation mechanism of a highly excited carrier propagating in the antiferromagnetic background modeled by the $t$-$J$ Hamiltonian on a square lattice. We show that the relaxation consists of two distinct stages. The initial ultrafast stage with the relaxation time $τ\sim (\hbar/t_0)(J/t_0)^{-2/3}$ (where $t_0$ is the hopping integral and $J$ is the exchange interaction) is based on generation of string states in the close proximity of the carrier. This unusual scaling of $τ$ is obtained by means of comparison of numerical results with a simplified $t$-$J_z$ model on a Bethe lattice. In the subsequent (much slower) stage local spin excitations are carried away by magnons. The relaxation time on the two-leg ladder system is an order of magnitude longer due to the lack of string excitations. This further reinforces the importance of string excitations for the ultrafast relaxation in the two-dimensional system.

description: Given two weights $σ, w$ on $\mathbb R ^{n}$, the classical $g$-function satisfies the norm inequality $\lVert g (fσ)\rVert_{L ^2 (w)} \lesssim \lVert f\rVert_{L ^2 (σ)}$ if and only if the two weight Muckenhoupt $A_2$ condition holds, and a family of testing conditions holds, namely \begin{equation*} \iint_{Q (I)} (\nabla P_t (σ\mathbf 1_I)(x, t))^2 \; dw \, t dt \lesssim σ(I) \end{equation*} uniformly over all cubes $I \subset \mathbb R ^{n}$, and $Q (I)$ is the Carleson box over $I$. A corresponding characterization for the intrinsic square function of Wilson also holds.

Statistics and Computational Intelligence Tools for WCET Analysis in Multicore Architectures.
Creators: name: Tadeu Nogueira
Publisher: name: Zenodo
Year: 2022

description: Real-time systems consist of a set of tasks (pieces of code) that are recurrently released to execute and must meet deadlines. The correct design of such a system requires information on worst-case execution time (WCET) for each of its tasks. However, estimating WCET is becoming increasingly difficult due to the high complexity of hardware and software present in nowadays modern platforms. This has motivated the use of techniques to derive probabilistic worst-case execution time (pWCET). Most existing approaches are based on measuring the execution time of each system task running in the target platform. As the measurements are carried out during design time, collected samples may lead to unreliable (due to possible measurement bias) or non-representative estimates (due to difficulties in reproducing operational conditions). The need to make the samples to conform with statistical modeling assumptions is an additional source of difficulty. In this context, our work aims at developing pWCET estimating approaches capable of circumventing the mentioned problems. We modelled execution time in function of either occurring hardware-level events, using Linear Regression Analysis; or the number of executed instructions, using Extreme Value Statistics. In both cases, we analyzed runs of 15 benchmark programs in different environments. Preliminary results indicate that both research directions offer richer information on execution time behavior when compared to existing techniques.
Avaliação automática de mapas conceituais baseada na teoria da aprendizagem significativa

description: Concept map is a useful pedagogical tool which represent a student cognitive structure and help to promote meaningful learning. One difficulty found in the current literature concerns about evaluation of learning mediated by conceptual maps. Researches in the field of computer science and education have been investigated the problem of evaluating learning by comparing the student map with a reference map through computational tools. In our proposal we deal with the identification of the concepts of Ausubel Theory within the map construction process as well as the comparison of maps with reference maps. In this context, this work aims at constructing a proposal for conceptual map evaluation based on Ausubel theory through an architecture that brings together aspects for a structural and semantic analysis. In this sense, we hope to contribute to the area of Informatics in Education through an architectural framework that can subsidize the automation of the concept map evaluation process, which is closer to a meaningful learning evaluation to support teachers and students in the teaching-learning process.
