description: Fake news spreading, with the aim of manipulating individuals' perceptions of facts, is now recognized as a major problem in many democratic societies. Yet, to date, little has been understood about how fake news spreads on social networks, what the influence of the education level of individuals is, when fake news is effective in influencing public opinion, and what interventions might be successful in mitigating their effect. In this paper, starting from the recently introduced kinetic multi-agent model with competence by the first two authors, we propose to derive reduced-order models through the notion of social closure in the mean-field approximation that has its roots in the classical hydrodynamic closure of kinetic theory. This approach allows to obtain simplified models in which the competence and learning of the agents maintain their role in the dynamics and, at the same time, the structure of such models is more suitable to be interfaced with data-driven applications. Examples of different Twitter-based test cases are described and discussed.

description: High quality energy systems information is a crucial input to energy systems research, modeling, and decision-making. Unfortunately, actionable information about energy systems is often of limited availability, incomplete, or only accessible for a substantial fee or through a non-disclosure agreement. Recently, remotely sensed data (e.g., satellite imagery, aerial photography) have emerged as a potentially rich source of energy systems information. However, the use of these data is frequently challenged by its sheer volume and complexity, precluding manual analysis. Recent breakthroughs in machine learning have enabled automated and rapid extraction of useful information from remotely sensed data, facilitating large-scale acquisition of critical energy system variables. Here we present a systematic review of the literature on this emerging topic, providing an in-depth survey and review of papers published within the past two decades. We first taxonomize the existing literature into ten major areas, spanning the energy value chain. Within each research area, we distill and critically discuss major features that are relevant to energy researchers, including, for example, key challenges regarding the accessibility and reliability of the methods. We then synthesize our findings to identify limitations and trends in the literature as a whole, and discuss opportunities for innovation. These include the opportunity to extend the methods beyond electricity to broader energy systems and wider geographic areas; and the ability to expand the use of these methods in research and decision making as satellite data become cheaper and easier to access. We also find that there are persistent challenges: limited standardization and rigor of performance assessments; limited sharing of code, which would improve replicability; and a limited consideration of the ethics and privacy of data.

description: We analyze constraints on parameters characterizing the pre-inflating universe in an open inflation model with a present slightly open $Λ$CDM universe. We employ an analytic model to show that for a broad class of inflation-generating effective potentials, the simple requirement that some fraction of the observed dipole moment represents a pre-inflation isocurvature fluctuation allows one to set upper and lower limits on the magnitude and wavelength scale of pre-inflation fluctuations in the inflaton field, and the curvature of the pre-inflation universe, as a function of the fraction of the total initial energy density in the inflaton field as inflation begins. We estimate that if the pre-inflation contribution to the current CMB dipole is near the upper limit set by the {\it Planck} Collaboration then the current constraints on $Λ$CDM cosmological parameters allow for the possibility of a significantly open $Ω_{i} \le 0.4$ pre-inflating universe for a broad range of the fraction of the total energy in the inflaton field at the onset of inflation. This limit to $Ω_{i}$ is even smaller if a larger dark-flow tilt is allowed.

description: Machine Learning algorithms have played an important role in hadronic jet classification problems. The large variety of models applied to Large Hadron Collider data has demonstrated that there is still room for improvement. In this context Quantum Machine Learning is a new and almost unexplored methodology, where the intrinsic properties of quantum computation could be used to exploit particles correlations for improving the jet classification performance. In this paper, we present a brand new approach to identify if a jet contains a hadron formed by a $b$ or $\bar{b}$ quark at the moment of production, based on a Variational Quantum Classifier applied to simulated data of the LHCb experiment. Quantum models are trained and evaluated using LHCb simulation. The jet identification performance is compared with a Deep Neural Network model to assess which method gives the better performance.

description: There is a dearth of information about the working people of San Antonio and their economic environment. True, some limited studies have been made of their housing facilities, their health and their occupations, but apparently no one has deemed it fruitful or significant enough to assemble the available data and to fit them into their social and economic context. This dissertation is devoted to describing and interpreting some of the various facets of existence which shaped the lives of San Antonians during the first four decades of the present century. Unfortunately, the reliability of the source material available for a study of this type varies considerably. United States Bureau of the Census Reports and Bulletins and the Monthly Labor Review published by the United States Department of Labor, Bureau of Labor Statistics, were utilized as primary sources of information. Publications of the Texas Bureau of Labor Statistics were consulted also, but limitations of facilities and personnel of the Texas Bureau detract from the reliability of those data. Files of various local unions in San Antonio were canvassed and in some cases proved very fruitful, particularly with regard to membership records and collective bargaining contracts. [...] [I]t was necessary to rely heavily upon personal interviews and newspaper files. Several hundred business executives, labor leaders, social workers, churchmen, public health officers, city officials and rank and file workers were kind enough to converse--some at considerable length--with the writer. Most of them were very cooperative and helpful [...]. Particularly with regard to the history of union organization, newspaper files and City Directories were resorted to extensively. Although attempts were made to corroborate the data thus secured, it was impossible to do so in many instances. As a result, inaccuracies, especially in quoting of opinions during strikes and other periods of tension, are likely to appear. Conflicting stories in the various papers were rationalized so far as possible

description: Η πανδημία του COVID-19 έχει επηρεάσει διάφορους τομείς της οικονομίας, συμπεριλαμβανομένων των ασφαλιστικών, και έχει γίνει πρόβλημα και σαφής καταλύτης για την καινοτομία. Η πανδημία έχει επισημάνει ορισμένη αναποτελεσματικότητα του παραδοσιακού μοντέλου αλληλεπίδρασης μεταξύ των ασφαλιστών και των πελατών τους και εστίασε στις προσπάθειες των ασφαλιστικών εταιρειών για καινοτομίες και επενδύσεις στο ψηφιακό μέλλον. Αυτή η εργασία έχει σκοπό να γενικεύσει τους μετασχηματισμούς του θεσμικού περιβάλλοντος στο οικοσύστημα InsurTech στο πλαίσιο της πανδημίας COVID-19 και να εντοπίσει τις προοπτικές για την ανάπτυξή της στην μεταπανδημική περίοδο. Η ανάλυση της λειτουργίας του InsurTech ως οικοσυστήματος κατέστησε αναγκαία την αναγνώριση προκλήσεων για την ασφαλιστική αγορά στο πλαίσιο του COVID-19. Ο μετασχηματισμός της ασφαλιστικής αγοράς υπό την επιρροή της ψηφιοποίησης των επιχειρηματικών διαδικασιών υπό τη σημασία της InsurTech διαμορφώνει το ανταγωνιστικό πλεονέκτημα. Για πολλές εταιρείες, η κρίση ενίσχυσε τις καινοτόμες αναπτυξιακές τους στρατηγικές και επιτάχυνε την εφαρμογή εργαλείων χρηματοοικονομικής τεχνολογίας στην επιχείρηση στο πλαίσιο του εκσυγχρονισμού της τεχνολογικής υποδομής. Chatbots, τηλεματική, Διαδίκτυο των πραγμάτων, μηχανική μάθηση, τεχνητή νοημοσύνη, χρησιμοποιούνται ευρέως ως προγνωστικές αναλύσεις κ.λπ. Στο μέλλον, η InsurTech θα παίζει επίσης ένα σημαντικό ρόλο στην εισαγωγή ψηφιακών καινοτομιών στην ασφαλιστική αγορά. Στόχος είναι να διερευνηθεί πόσο διαδεδομένη είναι η χρήση των ψηφιακών τεχνολογιών στις ασφαλιστικές πωλήσεις και ποιες αξίες αυτών των ψηφιακών τεχνολογιών γίνονται αντιληπτές από τους ασφαλιστικούς διαμεσολαβητές. Τα αποτελέσματα δείχνουν ότι ακόμη και στο χρονικό σημείο της πανδημίας, σε ένα υψηλό ποσοστό πωλήσεων, ο ψηφιακός μετασχηματισμός δεν έχει προχωρήσει ακόμη πολύ. Περαιτέρω αναλύσεις δείχνουν ότι οι αποκλειστικοί πράκτορες και οι νεότεροι άνθρωποι είναι πιο μπροστά στον ψηφιακό μετασχηματισμό παρόλο που ο COVID-19 ωθεί την ψηφιακή ζωή σε όλες τις ηλικίες και κοινωνικές τάξεις. Με βάση τα αποτελέσματά μας, αντλούνται κάποιες αρχικές συστάσεις για τη δράση του ασφαλιστή.

description: Na2Co2TeO6 is a proposed approximate Kitaev magnet, yet its actual magnetic interactions are elusive due to a lack of knowledge on the full excitation spectrum. Here, using inelastic neutron scattering and single crystals, we determine the system's temperature-dependent magnetic excitations over the entire Brillouin zone. Without committing to specific models, we unveil a distinct signature of the third-nearest-neighbor coupling in the spin waves, which signifies the associated distance as an emerging "soft link" in the ordered state. The presence of at least six non-overlapping spin-wave branches is at odds with all models proposed to date. Above the ordering temperature, persisting dynamic correlations can be described by equal-time magnetic structure factors of a hexagonal cluster, which reveal the leading instabilities. Our result sets definitive constraint on theoretical models for Na2Co2TeO6 and provides new insight for the materialization of the Kitaev model.

description: In our recent paper [Phys. Rev. E 90, 032132 (2014)] we have studied the dynamics of a mobile impurity particle weakly interacting with the Tonks-Girardeau gas and pulled by a small external force, $F$. Working in the regime when the thermodynamic limit is taken prior to the small force limit, we have found that the Bloch oscillations of the impurity velocity are absent in the case of a light impurity. Further, we have argued that for a light impurity the steady state drift velocity, $V_D$, remains finite in the limit $F\rightarrow 0$. These results are in contradiction with earlier works by Gangardt, Kamenev and Schecter [Phys. Rev. Lett. 102, 070402 (2009), Annals of Physics 327, 639 (2012)]. One of us (OL) has conjectured [Phys. Rev. A 91, 040101 (2015)] that the central assumption of these works - the adiabaticity of the dynamics - can break down in the thermodynamic limit. In the preceding Comment [Phys. Rev. E 92, 016101 (2015)] Schecter, Gangardt and Kamenev have argued against this conjecture and in support of the existence of Bloch oscillations and linearity of $V_D(F)$. They have suggested that the ground state of the impurity-fluid system is a quasi-bound state and that this is sufficient to ensure adiabaticity in the thermodynamic limit. Their analytical argument is based on a certain truncation of the Hilbert space of the system. We argue that extending the results and intuition based on their truncated model on the original many-body problem lacks justification.

Modelling the structural response of fire-exposed CLT compression members

Subjects: Fire safety engineering

description: Efforts to reduce the carbon footprint of the construction industry have fuelled interests in so-called sustainable construction materials. Engineered wood products such as cross laminated timber (CLT) and glued laminated timber have facilitated this transition owing to numerous advantages over steel or concrete in some structural applications. However, cross laminated timber, like other timber products, degrades and combusts under fire exposure, experiencing reductions in structural capacity in the process. The study presented in this paper aims to numerically evaluate the structural capacity of CLT walls, with reference to properties and procedures suggested in EN 1995-1-2, under both heating and decay phases of potential design fire curves, and then to perform a parametric study to investigate which CLT wall build-ups are better performing in fire, and why. A one-dimensional transient heat transfer model was employed to predict the in-depth temperature distributions in a CLT cross-section whilst accounting for temperature dependent thermal properties (modelled according to the advanced method outlined in Annex B of EN 1995-1-2). A decoupled structural model accounting for the reduction in strength and stiffness based on the thermomechanical properties, also outlined in Annex B of EN 1995-1-2, was then used to predict the crushing and buckling load capacity of the CLT. The widely applied reduced cross-section method (RCSM)of strength during cooling was also studied for illustrative purposes only. The intensity and duration of a fire influence the extent of reduction in capacity, and further strength reductions were observed during the decay phase, as expected. The RCSM, as currently implemented in EN 1995-1-2 was confirmed as being difficult to defend for elements in compression, compared to the advanced model, particularly to estimate the crushing capacity during heating and cooling. It is also shown that the governing mode of failure at ambient temperature may change during a fire (i.e., from crushing to buckling), a fact which should be borne in mind by designers of CLT buildings.

Contamination with spoilage organisms and Listeria monocytogenes are major concerns for quality and safety of cooked ready-to-eat (RTE) meat products. Thus, the objective of this study was to investigate the use of antimicrobial starch packaging films to control competitive microbiota and L. monocytogenes growth on a RTE ham product. Starch packaging films were prepared with different bioactives, gallic acid, chitosan, and carvacrol, using subcritical water technology. The viability of the incorporated strains on ham in contact with different antimicrobial starch packaging films was examined during 28-day storage period at 4 °C. Starch films with gallic acid had the least effect on ham antimicrobial activity; starch films with chitosan and carvacrol fully inhibited L. monocytogenes growth throughout 4 weeks of storage. RTE meat microbiota was more resistant to the antimicrobials than L. monocytogenes. Starch films loaded with chitosan or chitosan and carvacrol did not fully inhibit growth of RTE meat microbiota but delayed growth of RTE meat microbiota by one to two weeks. Moreover, competitive meat microbiota fully inhibited growth of L. monocytogenes. Therefore, antimicrobial starch packaging films prepared by subcritical water technology used in this study showed a promising effect on inhibiting L. monocytogenes in RTE ham.

description: Recent theoretical studies of Stimulated Brillouin Scattering (SBS) in nanoscale devices have led to an intense research effort dedicated to the demonstration and application of this nonlinearity in on-chip systems. The key feature of SBS in integrated photonic waveguides is that small, high-contrast waveguides are predicted to experience powerful optical forces on the waveguide boundaries, which are predicted to further boost the SBS gain that is already expected to grow dramatically in such structures because of the higher mode confinement alone. In all recent treatments, the effect of radiation pressure is included separately from the scattering action that the acoustic field exerts on the optical field. In contrast to this, we show here that the effects of radiation pressure and motion of the waveguide boundaries are inextricably linked. Central to this insight is a new formulation of the SBS interaction that unifies the treatment of light and sound, incorporating all relevant interaction mechanisms --- radiation pressure, waveguide boundary motion, electrostriction and photoelasticity --- from a rigorous thermodynamic perspective. Our approach also clarifies important points of ambiguity in the literature, such as the nature of edge-effects with regard to electrostriction, and of body-forces with respect to radiation pressure. This new perspective on Brillouin processes leads to physical insight with implications for the design and fabrication of SBS-based nanoscale devices.

The detector was biased at $66$ V in order to benefit from the Neganov-Trofimov-Luke amplification and resulting in a resolution on the energy of electron recoils of $4.46$ eV$_{ee}$ (RMS) and an analysis threshold of $30$ eV$_{ee}$. The sensitivity is limited by a dominant background not associated to charge creation in the detector. The search constrains a new region of parameter space for cross-sections down to $10^{-29}$ cm$^2$ and masses between $32$ and $100$ MeV$\cdot$c$^{-2}$. The achieved low threshold with the NbSi sensor shows the relevance of its use for athermal-phonon sensitive devices for low-mass DM searches.

description: The recent conjecture of a topologically-protected surface state in SmB$_6$ and the verification of robust surface conduction below 4 K have prompted a large effort to understand the surface states. Conventional Hall transport measurements allow current to flow on all surfaces of a topological insulator, so such measurements are influenced by contributions from multiple surfaces of varying transport character. Instead, we study magnetotransport of SmB$_6$ using a Corbino geometry, which can directly measure the conductivity of a single, independent surface. Both (011) and (001) crystal surfaces show a strong negative magnetoresistance at all magnetic field angles measured. The (011) surface has a carrier mobility of $122\text{ cm}^2/\text{V}\cdot\text{sec}$ with a carrier density of $2.5\times10^{13} \text{ cm}^{-2}$, which are significantly smaller than indicated by Hall transport studies. This mobility value can explain a failure so far to observe Shubnikov-de Haas oscillations. Analysis of the angle-dependence of conductivity on the (011) surface suggests a combination of a field-dependent enhancement of the carrier density and a suppression of Kondo scattering from native oxide layer magnetic moments as the likely origin of the negative magnetoresistance. Our results also reveal a hysteretic behavior whose magnitude depends on the magnetic field sweep rate and temperature. Although this feature becomes smaller when the field sweep is slower, does not disappear or saturate during our slowest sweep-rate measurements, which is much slower than a typical magnetotransport trace. These observations cannot be explained by quantum interference corrections such as weak anti-localization, but are more likely due to an extrinsic magnetic effect such as the magnetocaloric effect or glassy ordering.

description: The thermodynamic uncertainty relation (TUR) quantifies a relationship between current fluctuations and dissipation in out-of-equilibrium overdamped Langevin dynamics, making it a natural counterpart of the fluctuation-dissipation theorem in equilibrium statistical mechanics. For underdamped Langevin dynamics, the situation is known to be more complicated, with dynamical activity also playing a role in limiting the magnitude of current fluctuations. Progress on those underdamped TUR-like bounds has largely come from applications of the information-theoretic Cramér-Rao inequality. Here, we present an alternative perspective by employing large deviation theory. The approach offers a general, unified treatment of TUR-like bounds for both overdamped and underdamped Langevin dynamics built upon current fluctuations achieved by scaling time. The bounds we derive following this approach are similar to known results but with differences we discuss and rationalize.

description: First respondents to fires in structures face severe risks as both the fire and structural behaviour are unpredictable. While structural collapse may manifest some warning signs, these signs are not always easily identified which has led to the death of many fire fighters over the years. Both fire and structural fire simulation have come a long way and are now capable of assessing the thermomechanical behaviour of structures to a good degree of accuracy. However, such simulations take hundreds or thousands of engineering and computation hours. This paper explores performing these analyses a priori and using the generated database to train a recurrent neural network for real time prediction of potential failure. The analysis is performed on an aluminium reticulated roof structure that is constructed in Sichuan Fire Research Institute (Sichuan, China) and is expected to be tested to failure in fire in 2023. One hundred localised fire scenarios were used to cover the potential fire that will be used to induce the failure of the test roof. Heat transfer analyses for each section were then performed in OpenSEES followed by thermomechanical analysis in the same software. The generated results database was then cleaned and the data at several key locations were extracted and used to train a long short term memory recurrent neural network. The results of the predictions show that the artificial intelligence model can infer results with increasing accuracy the closer the structure is to failure. The real test of the accuracy of the model, however, will be during the fire experiment on the real structure. This would be the first time an artificial intelligence model for rapid forecasting of structural response in fire is built a priori and tested against a real fire.

description: In this paper we study quasi-Monte Carlo integration of smooth functions using digital nets. We fold digital nets over $\mathbb{Z}_{b}$ by means of the $b$-adic tent transformation, which has recently been introduced by the authors, and employ such \emph{folded digital nets} as quadrature points. We first analyze the worst-case error of quasi-Monte Carlo rules using folded digital nets in reproducing kernel Hilbert spaces. Here we need to permit digital nets with "infinite digit expansions," which are beyond the scope of the classical definition of digital nets. We overcome this issue by considering the infinite product of cyclic groups and the characters on it. We then give an explicit means of constructing good folded digital nets as follows: we use higher order polynomial lattice point sets for digital nets and show that the component-by-component construction can find good \emph{folded higher order polynomial lattice rules} that achieve the optimal convergence rate of the worst-case error in certain Sobolev spaces of smoothness of arbitrarily high order.

description: Visual-inertial odometry (VIO) systems traditionally rely on filtering or optimization-based techniques for egomotion estimation. While these methods are accurate under nominal conditions, they are prone to failure during severe illumination changes, rapid camera motions, or on low-texture image sequences. Learning-based systems have the potential to outperform classical implementations in challenging environments, but, currently, do not perform as well as classical methods in nominal settings. Herein, we introduce a framework for training a hybrid VIO system that leverages the advantages of learning and standard filtering-based state estimation. Our approach is built upon a differentiable Kalman filter, with an IMU-driven process model and a robust, neural network-derived relative pose measurement model. The use of the Kalman filter framework enables the principled treatment of uncertainty at training time and at test time. We show that our self-supervised loss formulation outperforms a similar, supervised method, while also enabling online retraining. We evaluate our system on a visually degraded version of the EuRoC dataset and find that our estimator operates without a significant reduction in accuracy in cases where classical estimators consistently diverge. Finally, by properly utilizing the metric information contained in the IMU measurements, our system is able to recover metric scene scale, while other self-supervised monocular VIO approaches cannot.

description: A quick review on the analytical aspects of holographic superconductors (HSC) with Weyl corrections has been presented. Mainly we focus on matching method and variations approaches. Different types of such HSC have been investigated, s-wave, p-wave and Stúckelberg ones. We also review the fundamental construction of a p-wave type , in which the non-Abelian gauge field is coupled to the Weyl tensor. The results are compared from numerics to analytical results.

description: It is well-known in thermodynamics that the creation of correlations costs work. It seems then a truism that if a thermodynamic transformation A->B is impossible, so will be any transformation that in sending A to B also correlates among them some auxiliary systems C. Surprisingly, we show that this is not the case for non-equilibrium thermodynamics of microscopic systems. On the contrary, the creation of correlations greatly extends the set of accessible states, to the point that we can perform on individual systems and in a single shot any transformation that would otherwise be possible only if the number of systems involved was very large. We also show that one only ever needs to create a vanishingly small amount of correlations (as measured by mutual information) among a small number of auxiliary systems (never more than three). The many, severe constraints of microscopic thermodynamics are reduced to the sole requirement that the non-equilibrium free energy decreases in the transformation. This shows that, in principle, reliable extraction of work equal to the free energy of a system can be performed by microscopic engines.
