description: Machine learning algorithms have become indispensable in today's world. They support and accelerate the way we make decisions based on the data at hand. This acceleration means that data structures that were valid at one moment could no longer be valid in the future. With these changing data structures, it is necessary to adapt machine learning (ML) systems incrementally to the new data. This is done with the use of online learning or continuous ML technologies. While deep learning technologies have shown exceptional performance on predefined datasets, they have not been widely applied to online, streaming, and continuous learning. In this retrospective of our tutorial titled Opportunities and Challenges of Online Deep Learning held at ECML PKDD 2023, we provide a brief overview of the opportunities but also the potential pitfalls for the application of neural networks in online learning environments using the frameworks River and Deep-River.

description: The resonant dynamics of mediated interactions supports zero-sound in a cold atom degenerate mixture of a single component fermion gas and a Bose-Einstein condensate (BEC). We characterize the onset of instability in the phase separation of an unstable mixture and we find a rich collective mode structure for stable mixtures with one undamped mode that exhibits an avoided crossing and a Landau-damped mode that terminates.

Am Beispiel verschiedener Politikszenarien (Zollsenkungen auf Kraftfuttermittel in der Schweizer Milchviehhaltung) wird eine Verknüpfung normativer und empirischer Ergebnisse dargestellt und ein Index für die Übereinstimmung einer Maßnahme mit den Erwartungen der betroffenen Bevölkerung gebildet. Die Ergebnisse zeigen, daß die heutigen Kraftfutterpreise für die Milchviehhaltung den Erwartungen der Schweizer Bevölkerung sowie ausgewählter Bevölkerungsgruppen (Produktivitätsorientierte, Ökologiesensible und Strukturbewahrende) in hohem Masse entsprechen. Preissenkungen, die zu einem erhöhten Kraftfuttereinsatz in der Milch-viehhaltung führen, entsprechen aus Gründen der Ökologie und der Versorgungssicherheit nicht den Erwartungen der Bevölkerung.

Nonlocal symmetries and nonlocal conservation laws of Maxwell’s equations in four-dimensional Minkowski space
Creators: name: The, Dennis
Publisher: name: University of British Columbia
Year: 2009

description: We derive new nonlocal symmetries and corresponding new nonlocal conservation laws for the free-space Maxwell's equations (ME) in 3+1 space-time dimensions. These results arise from a detailed point symmetry analysis of several potential systems associated with ME: (1) LPS: the standard Lagrangian potential system, (2) A-LPS: LPS augmented by the Lorentz gauge, (3) PS: a natural non-Lagrangian potential system with dual vector potentials, and (4) A-PS: PS augmented by dual Lorentz gauges. The well-known (local) space-time symmetries and (local) energy-momentum conservation laws are shown to be recovered from the point symmetries of LPS and A-LPS. The point symmetry structure of A-PS is much richer: inversion and vector rotation / boost symmetries arise which yield nonlocal symmetries of ME. Through an embedding of the set of local PS and A-PS symmetries into the set of (local and nonlocal) ME adjoin-symmetries, an explicit formula is given for constructing ME conservation laws from PS and A-PS symmetries. The resulting ME conservation laws are completely classified with respect to their locality or nonlocality. This classification relies on an important cohomology result for ME for which a (partial) proof is given using tensorial methods. The work in this thesis extends the previously known classes of symmetries and conservation laws admitted by ME, and emphasizes the utility of potential systems and gauge constraints in their construction.

Towards a Wittgensteinian Aesthetics. Wollheim and the Analysis of Aesthetic Practices

Year: 2013

description: In order to investigate the possibility to develop Wittgenstein's suggestions about aesthetics, this paper will focus on the organic perspective elaborated by Richard Wollheim in «Art and Its Objects». In this regard we will try to emphasize how the concept of art as a "form of live" - explicit in Wollheim - involves the analysis of the practices embodied in the experience of art starting from those of representation. The inception modes of such practices of representation need to be described in the use of specific anthropological abilities related to perception patterns that go beyond the mere statement of facts, in a fusion among aesthetic, cognitive and emotional levels. Deepening the relationships both between lived experience and expression, and expression and understanding, we will try to point out how Wollheim (and Wittgenstein) places any rhetoric of the ineffable out of the game, even regarding the analysis of the aesthetic experience.

description: Using a squential logit model and a mixed-effects logistic regression approach this empirical study investigates factors for the adoption of automatic milking technology (AMS) at the farm level accounting for problems of sequential sample selection and behaviour identification. The results suggest the importance of the farmer’s risk perception, significant effects of peer-group behaviour, and a positive impact of previous innovation experiences.

description: We consider the effects of active-sterile secret neutrino interactions, mediated by a new pseudoscalar particle, on high- and ultra high-energy neutrino fluxes. In particular, we focus on the case of 3 active and 1 sterile neutrino coupled by a flavor dependent interaction, extending the case of 1 active and 1 sterile neutrino we have recently examined. We find that, depending on the kind of interaction of sterile neutrino with the active sector, new regions of the parameter space for secret interactions are now allowed leading to interesting phenomenological implications on two benchmark fluxes we consider, namely an astrophysical power law flux, in the range below 100 PeV, and a cosmogenic flux, in the Ultrahigh energy range. First of all, the final active fluxes can present a measurable depletion observable in future experiments. Especially, in the case of only tau neutrino interacting, we find that the effects on the astrophysical power law flux can be so large to be already probed by the IceCube experiment. Moreover, we find intriguing features in the energy dependence of the flavor ratio.

description: Ex-post evaluation of agricultural research is aimed to empirically provide evidence of past investments’ effectiveness. This paper is intended to measure the immediate impact of livestock research activities on cattle farmers’ knowledge about trypanosomosis and its therapeutic and preventive control strategies. According to the quasi-experimental design of the intervention, it is shown that its impact will be adequately estimated by propensity score matching (PSM). Based on data collected according to a knowledge, attitude and practice (KAP) questionnaire in the region of Kénédougou that is common to Mali and Burkina Faso, results indicate a significant gain in farmers’ know-how due to participation in livestock research activities.
The quantum fidelity for the time-dependent singular quantum oscillator

Publisher: name: arXiv

Subjects: subject: Mathematical Physics (math-ph)

description: In this paper we perform an exact study of ``Quantum Fidelity'' (also called Loschmidt Echo) for the time-periodic quantum Harmonic Oscillator of Hamiltonian : $$ \hat H\_{g}(t):=\frac{P^2}{2}+ f(t)\frac{Q^2}{2}+\frac{g^2}{Q^2} $$ when compared with the quantum evolution induced by $\hat H\_{0}(t)$ ($g=0$), in the case where $f$ is a $T$-periodic function and $g$ a real constant. The reference (initial) state is taken to be an arbitrary ``generalized coherent state'' in the sense of Perelomov. We show that, starting with a quadratic decrease in time in the neighborhood of $t=0$, this quantum fidelity may recur to its initial value 1 at an infinite sequence of times {$t\_{k}$}. We discuss the result when the classical motion induced by Hamiltonian $\hat H\_{0}(t)$ is assumed to be stable versus unstable. A beautiful relationship between the quantum and the classical fidelity is also demonstrated.
Reforecasting the November 1994 flooding of Piedmont with a convection-permitting model
Creators: name: Capecchi, Valerio
Publisher: name: arXiv
Year: 2020
Subjects: subject: Atmospheric and Oceanic Physics (physics.ao-ph)
subject: FOS: Physical sciences

description: The Piedmont region in Italy was affected by a heavy rainfall event in November 1994. On the 4th convective cells involved the coastal mountains of the region. On the 5th and early 6th, there were abundant precipitations, related to orographic lift and low-level convergences, in the Alpine area. This study aims to evaluate whether a convection-permitting model provides more valuable information with respect to past numerical experiments. Results for the 4th of November show that the cloud-resolving model successfully reconstructs the structure of precipitation systems on the downstream side of the coastal mountains. As regards the precipitations of the 5th of November, no added value is found. However, we provide evidence of the anomalously intense transport of moist air from the tropical and subtropical Atlantic and postulate how such transport is responsible for reducing the stability of the flow impinging on the Alps.

description: It is shown that exact solutions may be found for the energy eigenvalue problem generated by the class of semirelativistic Hamiltonians of the form H = sqrt{m^2+p^2} + hat{V}, where hat{V} is a non-local potential with a separable kernel of the form V(r,r') = - sum_{i=1}^n v_i f_i(r)g_i(r'). Explicit examples in one and three dimensions are discussed, including the Yamaguchi and Gauss potentials. The results are used to obtain lower bounds for the energy of the corresponding N-boson problem, with upper bounds provided by the use of a Gaussian trial function.

description: The key question of this paper is why farmers in Kosovo leave land fallow when the total land of their farms is rather small and households are rather large. In order to elicit some barriers to land utilisation in Kosovo, the paper is based on a comprehensive survey investigating agricultural households’ perceptions of production and market conditions, and employs several households and farm characteristics to empirically approximate the significance of different factors for leaving land fallow and not using it for production purposes. Three different models have been estimated. All estimated model specifications show a statistical significance at a satisfactory level and no severe signs of misspecification. One of the main factors farmers stated for their decision to leave land fallow was the low profitability of farming. The increase in incentives to farmers by improving market institutions up- and downstream is one measure which could alleviate the barriers to land use. Larger arable areas decrease the probability for fallow land. This emphasises the need for land consolidation.

description: As an attempt to understand the homochirality of organic molecules in life, a chemical reaction model is proposed where the production of chiral monomers from achiral substrate is catalyzed by the polymers of the same enatiomeric type. This system has to be open because in a closed system the enhanced production of chiral monomers by enzymes is compensated by the associated enhancement in back reaction, and the chiral symmetry is conserved. Open flow without cross inhibition is shown to lead to the chirality selection in a general model. In polymerization, the influx of substrate from the ambience and the efflux of chiral products for purposes other than the catalyst production make the system necessarily open. The chiral symmetry is found to be broken if the influx of substrate lies within a finite interval. As the efficiency of the enzyme increases, the maximum value of the enantiomeric excess approaches unity so that the chirality selection becomes complete.

A new contamination model for robust estimation with large high-dimensional data sets
Creators: name: Alqallaf, Fatemah Ali
Publisher: name: University of British Columbia
Year: 2009

description: Data sets can be very large, highly multidimensional and of mixed quality. This thesis provides feasible and robust methods for estimating multivariate location and scatter matrix for such data. Our estimates scale well to very large sample sizes and dimensions and are resistant to the presence of multivariate outliers. Statisticians use contamination or mixture models to study the performance of robust alternatives to classical statistical procedures. Most multivariate contamination models for numeric data proposed to date (see Hampel et al., 1986) assume that the majority of the observations comes from a nominal distribution such as a multivariate normal distribution, while the remainder comes from another multivariate distribution that generates outliers. We stress that such outliers could be "bad" data due to recording errors of all kinds, or they could be a highly informative subset of the data that leads to the discovery of unexpected knowledge in areas such as business operations, credit card fraud, and even the analysis of performance statistics of professional athletes. Unfortunately, the previously available models do not adequately represent reality for many multivariate data sets that arise in practice. It may often happen that outliers occur in each of the variables independently of the other variables or in special dependency patterns. We introduce a new contamination model that overcomes the main drawbacks of the current models by taking into account different sources of variability in the data, and allowing greater flexibility. Moreover, our model permits for situations where extreme values of one or more variables (not necessarily outliers) may increase the likelihood of outliers or gross errors in other variables. There is a large statistical literature on robust covariance and correlation matrix estimates, with an emphasis on affine equivariant estimates that possess high breakdown points and small worst case biases. All such estimates have unacceptable exponential complexity 2P in the number of variables p. And one of the more attractive of these estimates, the Stahel-Donoho estimate, has an unacceptable quadratic complexity n2 in the number of observations n. These estimates may be applied in large data applications with large p and n only by the use of adhoc sampling methods that render the robustness properties of the estimates unclear. In this thesis we focus on pairwise robust scatter matrix estimates and coordinate-wise location estimates. The pairwise scatter estimates are based on coordinate-wise robust transformations (the quadrant correlation estimate, and the coordinate-wise Huberized estimates). We show that such estimates are computationally simple, and have attractive robustness properties under the existing and the newly proposed contamination models.

description: As service-oriented architecture becoming one of the most prevalent techniques to rapidly deliver functionalities to customers, increasingly more reusable software components have been published online in forms of web services. To create a mashup, it gets not only time-consuming but also error-prone for developers to find suitable services from such a sea of services. Service discovery and recommendation has thus attracted significant momentum in both academia and industry. This paper proposes a novel incremental recommend-as-you-go approach to recommending next potential service based on the context of a mashup under construction, considering services that have been selected to the current step as well as its mashup goal. The core technique is an algorithm of learning the embedding of services, which learns their past goal-driven context-aware decision making behaviors in addition to their semantic descriptions and co-occurrence history. A goal exclusionary negative sampling mechanism tailored for mashup development is also developed to improve training performance. Extensive experiments on a real-world dataset demonstrate the effectiveness of our approach.

description: Consider a tree $T=(V,E)$ with root $\circ$ and edge length function $\ell:E\to\mathbb{R}_+$. The phylogenetic covariance matrix of $T$ is the matrix $C$ with rows and columns indexed by $L$, the leaf set of $T$, with entries $C(i,j):=\sum_{e\in[i\wedge j,o]}\ell(e)$, for each $i,j\in L$. Recent work [15] has shown that the phylogenetic covariance matrix of a large, random binary tree $T$ is significantly sparsified with overwhelmingly high probability under a change-of-basis with respect to the so-called Haar-like wavelets of $T$. This finding notably enables manipulating the spectrum of covariance matrices of large binary trees without the necessity to store them in computer memory but instead performing two post-order traversals of the tree. Building on the methods of [15], this manuscript further advances their sparsification result to encompass the broader class of $k$-regular trees, for any given $k\ge2$. This extension is achieved by refining existing asymptotic formulas for the mean and variance of the internal path length of random $k$-regular trees, utilizing hypergeometric function properties and identities.

Year: 2020

description: Cet article étudie le dialogue entre le discours construit à propos d’Ezra Pound par les arts visuels (peinture, photographie, sculpture, dessin) et la réappropriation poétique par l’auteur de certains de leurs traits esthétiques. D’une part, Pound élabore une poétique qui se nourrit des représentations contemporaines que les arts visuels font de lui. D’autre part, il existe une symbolique différente entre les représentations individuelles de Pound (qui ont aidé à forger le mythe du poète bohème, fou, insaisissable) et les représentations collectives, témoignant du rôle joué par Pound comme un acteur parmi d’autres dans l’ébullition artistique du début du XXe siècle. Comment ces représentations s’articulent-elles dans le temps avec certains masques poétiques d’Ezra Pound ? Quelles conclusions tirer d’une chronologie mettant en parallèle certains autoportraits poétiques de Pound avec les représentations picturales produites au même moment ? Quelle incidence le médium visuel a-t-il sur le portrait du poète ? On montrera que de nombreux portraits sont construits par le poète lui-même, qui cherche à imposer une image canonique tout en étant révolutionnaire.

description: Thermodynamic principles are often deceptively simple and yet surprisingly powerful. We show how a simple rule, such as the net flow of energy in and out of a moving atom under nonequilibrium steady state condition, can expose the shortcomings of many popular theories of quantum friction. Our thermodynamic approach provides a conceptual framework in guiding atom-optical experiments, thereby highlighting the importance of fluctuation-dissipation relations and long-time correlations between subsystems. Our results introduce consistency conditions for (numerical) models of nonequilibrium dynamics of open quantum systems.

description: This paper aims at simulating optimal prices satisfying public health recommendations in terms of nutrient adequacy. This implies to estimate a complete food demand system in order to compute price elasticities. Food consumption behaviors are described by an AI functional form [Deaton and Muellbauer(1980)] augmented to control for habit persistence. The demand system is estimated using the Iterated Least Square Estimator developed by Blundell and Robin (1999). We use French household expenditure data drawn from TNS Worldpanel covering 130 periods of 4 weeks from 1996 to 2005. Given the nature of our data, households are split into 8 cohorts based on two socio-demographic variables: date of birth and social status. A revised aggregation into 27 food groups is proposed in this paper. More precisely, commodities are grouped into homogeneous categories in terms of nutritional content and consumer preferences. Nutrient adequacy is defined using the MAR (Mean Adequacy Ratio), a nutrient only-based indicator. We calculate nutrient adequacy for 12 essential nutrients. Optimal prices are derived following Ramsey's approach to optimal taxation; Maximizing social welfare under nutritional constraints results in 27 optimal price variations or tax rates, each defined as a nonlinear function of all direct and cross price elasticities and the above mentioned indicator for all food groups.

description: We study the neutral hydrogen distribution and kinematics in the Local Group dwarf irregular galaxy IC 1613 and compare them with the ionized gas distribution and stellar content of the galaxy. We discuss several mechanisms which may be responsible for the origin of the observed complicated HI morphology and compare parameters of the most prominent kpc-scale HI structure with the multiple SNe scenario. The observations were performed with the Vary Large Array of NRAO with a linear resolution ~23 pc at the adopted distance of 725 kpc and the spectral channel width of 2.57 km/s. The numerical calculations have been provided with our 2.5D Lagrangian scheme based on the thin layer approximation. We found that the ISM of the galaxy is highly inhomogeneous and identified a number of intermediate-scale (200 pc - 300 pc in diameter) HI arcs and shells having expansion velocities of 10 to 20 km/s. Besides these shells, several giant holes and arc-shaped structures have been revealed, whose radii exceed several hundred parsecs. We found that parameters of the most prominent (M_HI = 2.8 x 10^7 Msol) kpc-scale structure and the level of the detected star formation activity are inconsistent with the multiple SNe hypothesis.

We observe that this length scale plays an important role when the tip to sample separation is less than about 10nm. Its origin can be modeled as a tiny protrusion at the end of the tip. The protrusion causes deviation from a logarithmic increase of capacitance versus decreasing height of the probe above the sample. We model this protrusion as a cone at the end of a sphere above an infinite plane. By fitting the frequency shift of the resonator versus height data (which is directly related to capacitance versus height) for our experimental setup, we find the protrusion size to be 3nm to 5nm. For one particular tip, the frequency shift of the NSMM relative to 2 micrometers away saturates at a value of about -1150 kHz at a height of 1nm above the sample, where the nominal range of sheet resistance values of the sample are 15 ohms to 150 ohms. Without the protrusion, the frequency shift would have followed the logarithmic dependence and reached a value of about -1500 kHz.

description: The potential impact of the current South African industrial biofuels strategy on the economic feasibility of biofuel production in South Africa is analysed and discussed. The analysis is then taken a step further by means of a scenario to analyse the potential impacts of higher global prices on the feasibility of a local biofuel industry. The BFAP sector model, a partial equilibrium model, is used to simulate the various impacts over the period 2009 to 2017. This study shows that the incentives and commitments, as presented through the strategy, are not sufficient to get a local biofuel industry up and running and make it sustainable in the long term.
HFB calculations with a microscopic pairing interaction

description: Hartree-Fock-Bogolyubov (HFB) calculations making use of a recently proposed microscopic effective pairing interaction are presented. The interaction was shown to reproduce the pairing properties provided by the realistic $AV18$ force very accurately in infinite matter. Although finite-ranged and non-local, it makes 3D HFB calculations in coordinate space tractable. As a first application, basic pairing properties of calcium isotopes in their ground-state are studied. By comparing the results with those obtained using a standard Density-Dependent Delta Interaction, the crucial isovector character of the microscopic interaction is highlighted.

Wittgenstein’s Concepts for an Aesthetics: Judgment and Understanding of Form
Creators: name: Borutti, Silvana
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2013

description: My paper seeks to maintain that in Wittgenstein there is more than the simple and obvious negation of artistic quality as the property of things, and thus a criticism of any essentialism. My reasoning will connect Wittgenstein’s evaluative idea of the aesthetic with its philosophical conception of Aspekt and the self-revealing character of the form. The themes this paper deals with are: the aesthetic judgment; the sensitivity toward rules; the aesthetic judgment as an example of the understanding of meaning. Aesthetic judgments are not to be understood as a philosophical paradigm but as a case of what, for Wittgenstein, is in general the aesthetic understanding of meaning.

description: Dynamic hedging effectiveness for soybean farmers in Rondonópolis (MT) with futures contracts of BM&F is calculated through optimal hedge determination, using the bivariate GARCH BEKK model, which considers the conditional correlations of the prices series, comparing the results with the minimum variance model effectiveness, calculated by OLS, the unhedged and the naïve hedge positions. The financial effectiveness of the dynamic hedge model is superior and can be used by farmers for several decision making purposes such as price discovery, hedging calibration, cash flow projections, market timing, among others.

description: We study two families of composite twisted Ramond fields (made by products of two operators) in the $\cal {N}=(4,4)$ supersymmetric D1-D5 SCFT$_2$ deformed by a marginal modulus operator away from its $(T^4)^N/ S_N$ free orbifold point. We construct the large-$N$ contributions to the four-point functions with two composite operators and two deformation fields. These functions allow us to derive short-distance OPE limits and to calculate the anomalous dimensions of the composite operators. We demonstrate that one can distinguish two sets of composite Ramond states with twists $m_1$ and $m_2$: protected states, for which $m_1+m_2=N$, and "lifted" states for which $m_1+m_2

Non-radially pulsating stars as microlensing sources

description: We study the microlensing of Non-Radially Pulsating (NRP) stars. Pulsations are formulated for stellar radius and temperature using spherical harmonic functions with different values of l,m. The characteristics of the microlensing light curves from NRP stars are investigated in relation to different pulsation modes. For the microlensing of NRP stars, the light curve is not a simple multiplication of the magnification curve and the intrinsic luminosity curve of the source star, unless the effect of finite source size can be ignored. Three main conclusions can be drawn from the simulated light curves. First, for modes with $m\neq0$ and when the viewing inclination is more nearly pole-on, the stellar luminosity towards the observer changes little with pulsation phase. In this case, high-magnification microlensing events are chromatic and can reveal the variability of these source stars. Second, some combinations of pulsation modes produce nearly degenerate luminosity curves (e.g., (l,m)=(3,0), (5,0)). The resulting microlensing light curves are also degenerate, unless the lens crosses the projected source. Finally, for modes involving m=1, the stellar brightness centre does not coincide with the coordinate centre, and the projected source brightness centre moves in the sky with pulsation phase. As a result of this time-dependent displacement in the brightness centroid, the time of the magnification peak coincides with the closest approach of the lens to the brightness centre as opposed to the source coordinate centre. Binary microlensing of NRP stars and in caustic-crossing features are chromatic.

3D dynamics of the Orion cloud complex -- Discovery of coherent radial gas motions at the 100-pc scale

description: We present the first study of the 3D dynamics of the gas in the entire southern Orion cloud complex. We used the parallaxes and proper motions of YSOs from Gaia DR2 as a proxy for gas distance and proper motion, and the gas radial velocities from archival CO data, to compute the space motions of the different star-forming clouds in the complex, including subregions in Orion A, Orion B, and two outlying cometary clouds. From the analysis of the clouds' orbits in space and time, we find that they were closest about 6 Myr ago and are moving radially away from roughly the same region in space. This coherent 100-pc scale radial motion supports a scenario where the entire complex is reacting to a major feedback event, which we name the Orion-BB (big blast) event. This event, which we tentatively associate with the recently discovered Orion X stellar population, shaped the distribution and kinematics of the gas we observe today, although it is unlikely to have been the sole major feedback event in the region. We argue that the dynamics of most of the YSOs carry the memory of the feedback-driven star formation history in Orion and that the majority of the young stars in this complex are a product of large-scale triggering, which can raise the star formation rate by at least an order of magnitude, as for the head of Orion A (the Integral Shape Filament). Our results imply that a feedback, compression, and triggering process lies at the genesis of the Orion Nebula Cluster and NGC2023/2024 in Orion B, thus confirming broadly the classical feedback-driven scenario proposed in Elmegreen & Lada (1977). The space motions of the well-known young compact clusters, $σ$ Orionis and NGC 1977, are consistent with this scenario. A momentum estimate suggests that the energy of a few to several supernovae is needed to power the coherent 3D gas motion we measure in this paper.

A variational principle for certain dissipative evolution equations
Creators: name: Tzou, Leo
Publisher: name: University of British Columbia
Year: 2009

description: We formulate a variational principle which models several first order parabolic Cauchy problems. Unlike the one proposed by Brezis-Ekeland in [2], this principle does not require the identification of the extremal value, which was a major hurdle for the applicability of their approach. Our method is based on a concept of "self-duality" inherent in many parabolic evolution equations, including those driven by the gradient of a convex energy functional. The new principle is used to provide global existence and uniqueness results of solutions for the heat equation (of course) but also for quasi-linear parabolic equations, porous media and fast diffusion equations.
