description: Ce sera, à n’en pas douter, contrainte et forcée par le contexte actuel (écologie, pression démographique), peut-être même à son insu, que l’humanité passera probablement à un régime végétal, non par choix moral. Le carnivorisme exprime un désir, il ne répond plus depuis longtemps, à un besoin ; c’est pourquoi il suscite une interrogation d’anthropologie philosophique (Burgat, 2017). Aussi l’institutionnalisation de l’option carnivore n’est-elle alimentaire et cuisinière que de manière seconde ; si les aspects nutritionnels et les explications de type matérialiste, d’une part, et les perspectives culturelles et idéalistes, d’autre part, ont capté la quasi-totalité des analyses, c’est parce que le champ de l’alimentation carnée est d’emblée cantonné à une sphère de pratiques et de représentations où l’animal n’est bon à penser que comme bon à manger.

description: We perform Bayesian model selection with parameter estimation to identify potentially lensed gravitational-wave images from the second observing run (O2) of Advanced LIGO and Advanced Virgo. Specifically, we compute the Bayesian evidence for a pair of events being lensed or not lensed (unlensed) using nested sampling. We consider the discrete coalescence phase shifts that can be induced if the gravitational-wave signal interacts with the lens caustics in the model selection. We find that the pair of events, GW170104 and GW170814 with a $π/2$ coalescence phase shift, has a significant Bayes factor ($B^L_{U}$ $\sim 1.98 \times 10^4$) favoring the lensing hypothesis. However, after taking into account the long time delay of approximately 7 months between events, the timing Bayes factor is significantly small ($B_t \sim 8.7\times10^{-2}$). The prior probability for detecting strongly lensed pairs at O2 sensitivity are exceedingly small for both galaxy and galaxy cluster lensing. Combining the lensing and timing Bayes factors with the prior odds on lensing gives an odds ratio of $O^L_{U} \sim 20$. However, the model dependence of the timing and prior odds factors does not provide strong evidence to demonstrate that the pair is strongly lensed.

description: Dam operators often do not know whether an auxiliary spillway will fail until it is loaded,which can be infrequent. Such failures have the potential to result in overall dam failure leading to loss oflife and substantial property damage. The purpose of this paper is to develop a screening technique toidentify potentially risky auxiliary spillways. The paper uses the National Inventory of Dams (NID) dataand analyzes a sample of 400 earthen dams with auxiliary spillways. The main innovation of the paper isto employ code to create multiple input files and analyze them in the Windows Dam Analysis Modules(WinDAM) C software. This technique is more efficient than the current functionality of WinDAM C thatevaluates one dam at a time. The proposed method serves as a quick screening and decision-making toolfor multiple embankments for extreme flooding events by identifying potentially risky auxiliary spillwaysthat may require in-depth analysis. The results of this screening found 75% of spillways are likely tosustain heavy damage. Additionally, heavy damage was related to narrower spillway widths.

description: The paper is devoted to the study of BRST charge in perturbed two dimensional conformal field theory. The main goal is to write the operator equation expressing the conservation law of BRST charge in perturbed theory in terms of purely algebraic operations on the corresponding operator algebra, which are defined via the OPE. The corresponding equations are constructed and their symmetries are studied up to the second order in formal coupling constant. It appears that the obtained equations can be interpreted as generalized Maurer-Cartan ones. We study two concrete examples in detail: the bosonic nonlinear sigma model and perturbed first order theory. In particular, we show that the Einstein equations, which are the conformal invariance conditions for both these perturbed theories, expanded up to the second order, can be rewritten in such generalized Maurer-Cartan form.

description: In this paper we propose a convolutional autoencoder to address the problem of motion infilling for 3D human motion data. Given a start and end sequence, motion infilling aims to complete the missing gap in between, such that the filled in poses plausibly forecast the start sequence and naturally transition into the end sequence. To this end, we propose a single, end-to-end trainable convolutional autoencoder. We show that a single model can be used to create natural transitions between different types of activities. Furthermore, our method is not only able to fill in entire missing frames, but it can also be used to complete gaps where partial poses are available (e.g. from end effectors), or to clean up other forms of noise (e.g. Gaussian). Also, the model can fill in an arbitrary number of gaps that potentially vary in length. In addition, no further post-processing on the model's outputs is necessary such as smoothing or closing discontinuities at the end of the gap. At the heart of our approach lies the idea to cast motion infilling as an inpainting problem and to train a convolutional de-noising autoencoder on image-like representations of motion sequences. At training time, blocks of columns are removed from such images and we ask the model to fill in the gaps. We demonstrate the versatility of the approach via a number of complex motion sequences and report on thorough evaluations performed to better understand the capabilities and limitations of the proposed approach.

Dynamics of variable stiffness composite shell structures using a Ritz approach

Subjects: classificationCode: 40

description: The design philosophy for high-performance lightweight composite structures has broadened significantly since the introduction of variable stiffness composites. Indeed, by tailoring stiffness distributions, variable stiffness composites have been shown to improve buckling performance and dynamic stability, as well as to modify dynamic response. When considering prestressed dynamically excited aerospace components, efficient linear analysis tools play a significant role in the early design of variable stiffness structures, allowing designers to identify many viable solutions with higher overall stiffness and fundamental frequency.In light of this, a single and multi-domain Ritz method for buckling, eigenfrequency, transient, and dynamic instability analysis of hygro-thermal and mechanically prestressed, variable stiffness, laminated, doubly-curved shell structures is presented. Sanders-Koiter based shell kinematics, within a first-order shear deformation theory framework, allows general orthogonal surfaces to be modelled without making any additional assumptions about the structure’s shallowness or thinness. The proposed Ritz method is efficient because it uses Legendre orthogonal polynomials as displacement trial functions, while the flexibility in modelling and design is provided by penalty techniques that allow stiffened variable angle tow shell structures to be modelled as an assembly of shell-like domains. The proposed approach is verified against published benchmark results and finite element solutions, showing excellent accuracy with approximately 65% fewer variables. Original parametric studies are carried out for cylindrical, spherical and variable?curvature shells, showing the flexibility that the variable stiffness concept provides for finding trade-off solutions for prestressed shell components. Then, original solutions for a prestressed, stiffened, variable angle tow shell structure are reported, demonstrating the reliability of the current approach in modelling the dynamic analysis of multi-part aerospace structures. Moreover, the dynamic behaviour of variable angle tow fairing shell geometries subject to hygro-thermomechanical prestress is examined, illustrating the validity of the variable stiffness concept in greatly improving the dynamic stability of critical doubly-curved variable-curvature components such as launch vehicle payload fairings.

description: Data outsourcing is a cost-effective solution for data owners to tackle issues such as large volumes of data, huge number of users, and intensive computation needed for data analysis. They can simply upload their databases to a cloud and let it perform all management works, including query processing. One problem with this service model is how query issuers can verify the query results they receive are indeed correct. This concern is legitimate because, as a third party, clouds may not be fully trustworthy, and as a large data center, clouds are ideal targets for hackers. There has been significant work on query result verification, but most consider only simple queries where query results can be attained by checking the raw data against the query conditions directly. In this paper, we consider the problem of enabling users to verify the correctness of the results of analytic queries. Unlike simple queries, analytic queries involve ranking functions to score a database, which makes it difficult to build data structures for verification purposes. We propose two approaches, namely one-signature and multi-signature, and show that they work well on three representative types of analytic queries, including top-k, range, and KNN queries, through both analysis and experiments.

Charged and Neutral Currents in a 3-3-1 Model with Right-Handed Neutrinos

description: The charged and the neutral currents are obtained by using a formal algebraical approach (developed and applied by the author) within the exact solution of a 3-3-1 gauge model with right-handed neutrinos. The entire Standard Model phenomenology is recovered without imposing any supplemental condition, but only by choosing an adecquate set of parameters from the very beginning of the calculus. A new and rich phenomenology regarding the particles and their currents occurs as well. The appealing feature of our results resides in the exact expressions of the currents which need not the adjustment usually due to the small mixing angle $ϕ$ between neutral bosons $Z$ and $Z^{\prime}$ (like in the most of the papers in the literature treating the same issue). The required mixing was considered and aleready performed as an intermediate step by the solving method itself, since the physical eigenstates of those bosons were determined and then identified in the neutral currents.

description: We introduce a hybrid "Modified Genetic Algorithm-Multilevel Stochastic Gradient Descent" (MGA-MSGD) training algorithm that considerably improves accuracy and efficiency of solving 3D mechanical problems described, in strong-form, by PDEs via ANNs (Artificial Neural Networks). This presented approach allows the selection of a number of locations of interest at which the state variables are expected to fulfil the governing equations associated with a physical problem. Unlike classical PDE approximation methods such as finite differences or the finite element method, there is no need to establish and reconstruct the physical field quantity throughout the computational domain in order to predict the mechanical response at specific locations of interest. The basic idea of MGA-MSGD is the manipulation of the learnable parameters' components responsible for the error explosion so that we can train the network with relatively larger learning rates which avoids trapping in local minima. The proposed training approach is less sensitive to the learning rate value, training points density and distribution, and the random initial parameters. The distance function to minimise is where we introduce the PDEs including any physical laws and conditions (so-called, Physics Informed ANN). The Genetic algorithm is modified to be suitable for this type of ANN in which a Coarse-level Stochastic Gradient Descent (CSGD) is exploited to make the decision of the offspring qualification. Employing the presented approach, a considerable improvement in both accuracy and efficiency, compared with standard training algorithms such as classical SGD and Adam optimiser, is observed. The local displacement accuracy is studied and ensured by introducing the results of Finite Element Method (FEM) at sufficiently fine mesh as the reference displacements. A slightly more complex problem is solved ensuring its feasibility.

description: Artificial Intelligence is everywhere today. But unfortunately, Agriculture has not been able to get that much attention from Artificial Intelligence (AI). A lack of automation persists in the agriculture industry. For over many years, farmers and crop field owners have been facing a problem of trespassing of wild animals for which no feasible solution has been provided. Installing a fence or barrier like structure is neither feasible nor efficient due to the large areas covered by the fields. Also, if the landowner can afford to build a wall or barrier, government policies for building walls are often very irksome. The paper intends to give a simple intelligible solution to the problem with Automated Crop Field Surveillance using Computer Vision. The solution will significantly reduce the cost of crops destroyed annually and completely automate the security of the field.

description: The magnetic field dependence of the oxygen-isotope (^{16}O/^{18}O) effect (OIE) on the in-plane magnetic field penetration depth λ_{ab} was studied in the hole-doped high-temperature cuprate superconductors YBa_2Cu_4O_8, Y_0.8Pr_0.2Ba_2Cu_3O_7-δ, and Y_0.7Pr_0.3Ba_2Cu_3O_7-δ. It was found that λ_ab for the ^{16}O substituted samples increases stronger with increasing magnetic field than for the ^{18}O ones. The OIE on λ_ab decreases by more than a factor of two with increasing magnetic field from μ_0H=0.2 T to μ_0H=0.6 T. This effect can be explained by the isotope dependence of the in-plane charge carrier mass m^\ast_{ab}.

description: JHKs near-infrared photometry of stars in the Phoenix dwarf galaxy is presented and discussed. Combining these data with the optical photometry of Massey et al. allows a rather clean separation of field stars from Phoenix members. The discovery of a Mira variable (P = 425 days), which is almost certainly a carbon star, leads to an estimate of the distance modulus of 23.10+/-0.18 that is consistent with other estimates and indicates the existence of a significant population of age ~2 Gyr. The two carbon stars of Da Costa have M{bol} = -3.8 and are consistent with belonging to a population of similar age; some other possible members of such a population are identified. A Da Costa non-carbon star is Delta Ks~0.3 mag brighter than these two carbon stars. It may be an AGB star of the dominant old population. The nature of other stars lying close to it in the Ks,(J-Ks) diagram needs studying.

description: Anomalous X-ray pulsars (AXPs) are thought to be magnetars, which are neutron stars with ultra strong magnetic field of $10^{14}$-- $10^{15}$ G. Their energy spectra below $\sim$10 keV are modeled well by two components consisting of a blackbody (BB) ($\sim$0.4 keV) and rather steep power-law (POW) function (photon index $\sim$2-4). Kuiper et al.(2004) discovered hard X-ray component above $\sim$10 keV from some AXPs. Here, we present the Suzaku observation of the AXP 1E 1841-045 at the center of supernova remnant Kes 73. By this observation, we could analyze the spectrum from 0.4 to 50 keV at the same time. Then, we could test whether the spectral model above was valid or not in this wide energy range. We found that there were residual in the spectral fits when fit by the model of BB + POW. Fits were improved by adding another BB or POW component. But the meaning of each component became ambiguous in the phase-resolved spectroscopy. Alternatively we found that NPEX model fit well for both phase-averaged spectrum and phase-resolved spectra. In this case, the photon indices were constant during all phase, and spectral variation seemed to be very clear. This fact suggests somewhat fundamental meaning for the emission from magnetars.

It is necessary to make sure whether general single field inflation can produce a large positive $f_{NL}$ before turning to other scenarios. We give some examples to generate a large positive $f_{NL}^{equil}$ in general single field inflation. Our models are different from ghost inflation. Due to the appearance of non-conventional kinetic terms, $f_{NL}^{equil}\gg1$ can be realized in single field inflation.

description: We consider the possibility of having a MeV right-handed neutrino as a dark matter constituent. The initial reason for this study was the 511 keV spectral line observed by the satellite experiment INTEGRAL: could it be due to an interaction between dark matter and baryons? Independently of this, we find a number of constraints on the assumed right-handed interactions. They arise in particular from the measurements by solar neutrino experiments. We come to the conclusion that such particles interactions are possible, and could reproduce the peculiar angular distribution, but not the rate of the INTEGRAL signal. However, we stress that solar neutrino experiments are susceptible to provide further constraints in the future.

description: All species interact with other species to form complex networks of connections. Such networks are a powerful way to represent ecological communities because they describe (i) the roles of individual species and (ii) the structure of the community as a whole in a single framework amenable to mathematical and computational analysis. In this thesis I consider a number of outstanding problems in network ecology. In Chapter 1, I examine the consequences for network structure of removing non-mutualistic interactions from plant-frugivore visitation networks. I find that plant-frugivore visitation networks act as a good proxy for mutualistic seed dispersal networks in terms of whole-network topology, but not when considering species- level structures. Chapter 2 deals with whether generalisation drives abundance or vice versa in plant-hummingbird pollination networks. I find evidence that abundance drives generalisation and use a simple model to show that neutral processes can explain broad patterns of species- level generalisation. In Chapter 3, I quantify the importance and vulnerability of mutualistic interactions to understand the risk that interaction extinction poses to communities. I conclude that (i) the interactions most important for community stability are those which are most vulnerable to extinction, and (ii) important and vulnerable interactions tend to be important and vulnerable wherever they occur. In Chapter 4, I consider motifs as an alternative to indices for characterising the structure of bipartite networks. I find that motifs capture significantly more information about network topology than indices and advocate adding bipartite motifs to the suite of analytical tools used by network ecologists. Chapter 5 describes a software package in R, MATLAB and Python for conducting motif analyses of bipartite networks. It uses novel mathematical formulations to dramatically reduce the computational time required for motif calculations compared to competing software.

description: It is well known that finding and measuring the masses of particles in the Minimal Supersymmetric Standard Model (MSSM) at the Large Hadron Collider (LHC) may be possible using invariant mass distributions in exclusive channels containing n_j jets and n_l leptons. We perform this analysis for the (n_j, n_l) = (0,4) decay of heavy Higgs bosons to neutralinos, pp \to H/A \to χ_i χ_j (i,j =2,3,4), which then decay to four leptons and two lightest neutralinos χ_1 via on-shell sleptons. When i=j and the sleptons are degenerate, our Monte Carlo study shows that the LHC will be able to measure the Higgs and relevant neutralino and slepton masses to roughly 30%; however, if one of these is already known within 5%, the other three may be found to equal or better accuracy. This would provide the first accurate measurement of the H/A mass via invariant mass distribution techniques.

Stress-free states of continuum dislocation fields: Rotations, grain boundaries, and the Nye dislocation density tensor

description: We derive general relations between grain boundaries, rotational deformations, and stress-free states for the mesoscale continuum Nye dislocation density tensor. Dislocations generally are associated with long-range stress fields. We provide the general form for dislocation density fields whose stress fields vanish. We explain that a grain boundary (a dislocation wall satisfying Frank's formula) has vanishing stress in the continuum limit. We show that the general stress-free state can be written explicitly as a (perhaps continuous) superposition of flat Frank walls. We show that the stress-free states are also naturally interpreted as configurations generated by a general spatially-dependent rotational deformation. Finally, we propose a least-squares definition for the spatially-dependent rotation field of a general (stressful) dislocation density field.

What We Can Learn From Visual Artists About Software Development

description: This paper explores software's role in visual art production by examining how artists use and develop software. We conducted interviews with professional artists who were collaborating with software developers, learning software development, and building and maintaining software. We found artists were motivated to learn software development for intellectual growth and access to technical communities. Artists valued efficient workflows through skilled manual execution and personal software development, but avoided high-level forms of software automation. Artists identified conflicts between their priorities and those of professional developers and computational art communities, which influenced how they used computational aesthetics in their work. These findings contribute to efforts in systems engineering research to integrate end-user programming and creativity support across software and physical media, suggesting opportunities for artists as collaborators. Artists' experiences writing software can guide technical implementations of domain-specific representations, and their experiences in interdisciplinary production can aid inclusive community building around computational tools.

description: Το ανταγωνιστικό και γρήγορα μεταβαλλόμενο περιβάλλον επιχειρήσεων σε συνδυασμό με το ότι τα περισσότερα έργα λογισμικού αδυνατούν να εκπληρώσουν τις απαιτήσεις που πρέπει, συνετέλεσε στη δημιουργία και χρησιμοποίηση των προτύπων και στη συνέχεια των αντιπροτύπων, και συγκεκριμένα αυτών που αφορούν στη διοίκηση έργων λογισμικού. Το γεγονός ότι τα αντιπρότυπα συλλαμβάνουν γνώση που δεν μπορεί να επιτύχει αποτελεσματικά την επικοινωνία ανάμεσα στον άνθρωπο και τα εργαλεία λογισμικού οδήγησε στη μοντελοποίησή τους με τη χρήση οντολογιών, οι οποίες αναπαριστούν τη γνώση και μπορούν να προσδιορίζουν μια διαμοιραζόμενη σύλληψη ιδέας. Για τη μοντελοποίηση των αντιπροτύπων χρησιμοποιούμε τις οντολογίες OWL, καθώς η OWL είναι μια δυναμική γλώσσα μοντελοποίησης και δεν έχει περιορισμένη εκφραστικότητα όπως άλλες αντίστοιχες. Ετσι, η μοντελοποίηση αυτή αποτελεί ένα σημαντικό εργαλείο στα χέρια των οργανισμών αφού η γνώση γίνεται ξεκάθαρη και εύκολα, προσεγγίσιμη, εξοικονομείται χρόνος και χρήμα και συγχρόνως εξασφαλίζεται ένα υγιές και ευχάριστο εργασιακό περιβάλλον.
description: The competitive and rapidly altered business environment, in combination with the fact that most software projects fail to meet the requirements they should, contributed to the creation and use of patterns firstly and antipatterns later and especially those antipatterns that refer to project management. The fact that antipatterns capture knoeledge that cannot effectively achieve the communication among people and software tools led to their modeling using ontologies, which represent knowledge and can determine widespread ideas. To model these antipatterns we use OWL ontologies, because OWL is a dynamic language and its expressiveness is not limited as that of other languages. In that way, modeling of antipatterns becomes an important tool for organizations as knowledge is now obvious and approachable, time and money are saved and at the same time a happy work environment is ensured.

description: In the 2002 AMS summer conference on ``Advances in Quantum Dynamics'' in Mount Holyoke Robert Powers proposed a sum operation for spatial E0-semigroups. Still during the conference Skeide showed that the Arveson system of that sum is the product of spatial Arveson systems. This product may but need not coincide with the tensor product of Arveson systems. The Powers sum of two spatial E0-semigroups is, therefore, up to cocycle conjugacy Skeide's product of spatial noises.

description: Memristors have been at the forefront of nanoelectronics research for the last decade, offering a valuable component to reconfigurable computing. Their attributes have been studied extensively along with applications that leverage their state-dependent programmability in a static fashion. However, practical applications of memristor-based AC circuits have been rather sparse, with only a few examples found in the literature where their use is emulated at higher frequencies. In this work, we study the behavior of metal-oxide memristors under an AC perturbation in a range of frequencies, from 10^3 to 10^7 Hz. Metal-oxide memristors are found to behave as RC low-pass filters and they present a variable cut-off frequency when their state is switched, thus providing a window of reconfigurability when used as filters. We further study this behaviour across distinct material systems and we show that the usable reconfigurability window of the devices can be tailored to encompass specific frequency ranges by amending the devices' capacitance. This study extends current knowledge on metal-oxide memristors by characterising their frequency dependent characteristics, providing useful insights for their use in reconfigurable AC circuits.

description: In this paper, we construct a family of probability measures, by penalizations of a Walsh Brownian motion with a weight dependent on its value and its local time at a time t. We prove that this family converges to a probability measure as t tends to infinity, and we study the behaviour of this limit measure.

In this correspondence we propose an intrusion detection algorithm based on the estimation of Hurst exponent. The algorith input data comes from the network traffic. This data is seperated into several segments and after being hashed by applying a hash function to the algorithm can use them in order to estimate the Hurst exponent.
