description: Communication between workers and the master node to collect local stochastic gradients is a key bottleneck in a large-scale federated learning system. Various recent works have proposed to compress the local stochastic gradients to mitigate the communication overhead. However, robustness to malicious attacks is rarely considered in such a setting. In this work, we investigate the problem of Byzantine-robust compressed federated learning, where the attacks from Byzantine workers can be arbitrarily malicious. We theoretically point out that different to the attacks-free compressed stochastic gradient descent (SGD), its vanilla combination with geometric median-based robust aggregation seriously suffers from the compression noise in the presence of Byzantine attacks. In light of this observation, we propose to reduce the compression noise with gradient difference compression so as to improve the Byzantine-robustness. We also observe the impact of the intrinsic stochastic noise caused by selecting random samples, and adopt the stochastic average gradient algorithm (SAGA) to gradually eliminate the inner variations of regular workers. We theoretically prove that the proposed algorithm reaches a neighborhood of the optimal solution at a linear convergence rate, and the asymptotic learning error is in the same order as that of the state-of-the-art uncompressed method. Finally, numerical experiments demonstrate the effectiveness of the proposed method.
Charmonium and meson-molecule hybrid tetraquarks - Vector meson width and the isospin breaking in the X(3872) decay

description: In the X(3872) decay, both of the J/ψππ and J/ψπππ branching fractions are observed experimentally, and their sizes are comparable to each other. In order to clarify the mechanism to cause such a large isospin violation, we investigate X(3872) employing a model of coupled-channel two-meson scattering with a ccbar core. The two-meson states consist of D0Dbar*0, D+Dbar*-, J/ψρ, and J/ψω. The effects of the ρ and ω meson width are also taken into account. We calculate the transfer strength from the ccbar core to the final two-meson states. It is found that very narrow J/ψρ and J/ψω peaks appear very close to the D0Dbar*0 threshold for a wide range of variation in the parameter sets. The size of the J/ψρ peak is almost the same as that of J/ψω, which is consistent with the experiments. The large width of the ρ meson makes the originally small isospin violation by about five times larger.

description: It is an attractive hypothesis that the spatial structure of visual cortical architecture can be explained by the coordinated optimization of multiple visual cortical maps representing orientation preference (OP), ocular dominance (OD), spatial frequency, or direction preference. In part (I) of this study we defined a class of analytically tractable coordinated optimization models and solved representative examples in which a spatially complex organization of the orientation preference map is induced by inter-map interactions. We found that attractor solutions near symmetry breaking threshold predict a highly ordered map layout and require a substantial OD bias for OP pinwheel stabilization. Here we examine in numerical simulations whether such models exhibit biologically more realistic spatially irregular solutions at a finite distance from threshold and when transients towards attractor states are considered. We also examine whether model behavior qualitatively changes when the spatial periodicities of the two maps are detuned and when considering more than 2 feature dimensions. Our numerical results support the view that neither minimal energy states nor intermediate transient states of our coordinated optimization models successfully explain the spatially irregular architecture of the visual cortex. We discuss several alternative scenarios and additional factors that may improve the agreement between model solutions and biological observations.

 Kahl (1931) redescribed this species, and Borror (1963a) described its infraciliature but gave only a diagram of the buccal morphology. Pan et al. (2010) offered improved diagnoses of this species based on a Chinese population. Cells of the North American population matched previous descriptions of the species in all morphological characters, except body size in vivo (50–70 × 25–35 μm vs 30–50 × 15–30 μm).

description: This chapter is a review of some methods used for the computation of relativistic atomic and molecular models based on the Dirac equation. In the linear case, we briefly describe finite basis set approaches, including ones that are generated numerically, perturbation theory and effective Hamiltonians procedures, direct variational methods based on nonlinear transformations, min-max formulations and constrained minimizations. In the atomic case, we describe the MCDF method and some ways to solve numerically the homogeneous and inhomogeneous Dirac-Fock equations. Finally, we describe also some numerical methods relevant to the case of molecules.

description: We demonstrate high accuracy calculations for the HeH$^+$ molecule using newly developed analytic formulas for two-center two-electron integrals with exponential functions. The Born-Oppenheimer potential for the ground electronic $^1Σ^+$ state is obtained in the range of 0.1 -- 60 au with precision of about $10^{-12}$ au. As an example at the equilibrium distance $r=1.463\,283$ au the Born-Oppenheimer potential amounts to $-2.978\,708\,310\,771(1)$. Obtained results lay the ground for theoretical predictions in HeH$^+$ with spectroscopic precision.

description: Archival optical spectra from the Sloan Digital Sky Survey of two optically faint flat spectrum protostars, IRAS 04369+2539 and IRAS 05451+0037, show strong emission-line features including -- notably -- clear and broad emission across several molecular bands of TiO and VO. The molecular emission is indicative of dense, warm circumstellar gas and has been seen previously in only one object: the flat spectrum protostar IRAS 20496+4354 during a strong optical outburst (PTF 10nvg; Covey et al. 2011). The presence of broad molecular emission features in two additional objects having similar mid-infrared properties (but not known to be undergoing outbursts) could provide new insight into phases of rapid accretion / outflow at early stages of the protoplanetary disk. At present, the relevant geometry and the formation or heating mechanisms responsible for the observed TiO / VO cooling emission remain unexplained.

description: Computer Mediated Communication (CMC) has brought about a revolution in the way the world communicates with each other. With the increasing number of people, interacting through the internet and the rise of new platforms and technologies has brought together the people from different social, cultural and geographical backgrounds to present their thoughts, ideas and opinions on topics of their interest. CMC has, in some cases, gave users more freedom to express themselves as compared to Face-to-face communication. This has also led to rise in the use of hostile and aggressive language and terminologies uninhibitedly. Since such use of language is detrimental to the discussion process and affects the audience and individuals negatively, efforts are being taken to control them. The research sees the need to understand the concept of flaming and hence attempts to classify them in order to give a better understanding of it. The classification is done on the basis of type of flame content being presented and the Style in which they are presented.

description: In this paper we study pricing of American put options on the Black and Scholes market with a stochastic interest rate and finite-time maturity. We prove that the option value is a $C^1$ function of the initial time, interest rate and stock price. By means of Ito calculus we rigorously derive the option value's early exercise premium formula and the associated hedging portfolio. We prove the existence of an optimal exercise boundary splitting the state space into continuation and stopping region. The boundary has a parametrisation as a jointly continuous function of time and stock price, and it is the unique solution to an integral equation which we compute numerically. Our results hold for a large class of interest rate models including CIR and Vasicek models. We show a numerical study of the option price and the optimal exercise boundary for Vasicek model.

description: We compute a certain class of corrections to (specific) screening lengths in strongly coupled nonabelian plasmas using the AdS/CFT correspondence. In this holographic framework, these corrections arise from various higher curvature interactions modifying the leading Einstein gravity action. The changes in the screening lengths are perturbative in inverse powers of the 't Hooft coupling or of the number of colours, as can be made precise in the context where the dual gauge theory is superconformal. We also compare the results of these holographic calculations to lattice results for the analogous screening lengths in QCD. In particular, we apply these results within the program of making quantitative comparisons between the strongly coupled quark-gluon plasma and holographic descriptions of conformal field theory.

description: We develop a hyperparameter optimisation algorithm, Automated Budget Constrained Training (AutoBCT), which balances the quality of a model with the computational cost required to tune it. The relationship between hyperparameters, model quality and computational cost must be learnt and this learning is incorporated directly into the optimisation problem. At each training epoch, the algorithm decides whether to terminate or continue training, and, in the latter case, what values of hyperparameters to use. This decision weighs optimally potential improvements in the quality with the additional training time and the uncertainty about the learnt quantities. The performance of our algorithm is verified on a number of machine learning problems encompassing random forests and neural networks. Our approach is rooted in the theory of Markov decision processes with partial information and we develop a numerical method to compute the value function and an optimal strategy.

description: This paper presents the theoretical concepts of educational trajectoriesi that refers to how individuals proceed through different educational stages, how they combine them with other life spheres, how they cope with transitions and how they take decisions regarding their educational career. In the European knowledge societies, it becomes evident the interactions between education and life courses, deriving both from the changes in the human life styles and needs and in the re-conceptualisation of education into (lifelong) learning. European social and educational researches repeatedly warn about the risk that under present conditions learning becomes more than never a powerful factor of social reproduction than of equal opportunities. This paper aims at contributing at the current debate on education and disadvantage, indicating the interactive approach as the most suitable to understand and therefore counteract this misleading effect of education.

description: Across European countries, the expansion of education has increased during the 20th century the opportunities of young people’s access to and within schooling, but it has not reduced socioeconomic and cultural inequality both in term of labour market’s entry and participation to the democratic public life. This paper proposes an analysis of the ways in which education systems are institutionalised in Europe and the effects of this institutionalisation on educational inequality, young people’ labor market entry and the promotion of their active citizenship: three hot topics in the EU agenda framing the implementation of the European knowledge societies. Educational inequality becomes particularly evident at the transition point from lower to upper secondary education as this passage confronts young people with new (adult) expectations, status and practices and contributes to their positioning in a segmented labor market and an unequal society. Therefore, our special focus is set on the kinds of transitions foreseen in the education systems of the eight countries participating to an EU-funded research project on the Governance of Educational Trajectories in Europe (GOETE). The aim is to highlight how different the tasks of education are interpreted through the systemic structure of the different national education systems.

description: The subject of the paper is the derivation and analysis of evolution Galerkin schemes for the two dimensional Maxwell and linearized Euler equations. The aim is to construct a method which takes into account better the infinitely many directions of propagation of waves. To do this the initial function is evolved using the characteristic cone and then projected onto a finite element space. We derive the divergence-free property and estimate the dispersion relation as well. We present some numerical experiments for both the Maxwell and the linearized Euler equations.
Il pensiero come “salto”: educazione, soggetto ed esperienza in John Dewey
Creators: name: D’Agnese, Vasco
Publisher: name: Dipartimento di Scienze Dell’Educazione «Giovanni Maria Bertin» - Università di Bologna
Year: 2016
Subjects: Dewey; educazione incertezza; pensiero; soggetto

description: Questo lavoro analizza i temi del pensiero e del soggetto così come emergono dall’opera deweyana e discute le implicazioni pedagogiche di tale analisi. Il lavoro parte dalla confutazione dell’equiparazione fra pensiero e pensiero riflessivo, equiparazione che, di fatto, ha avuto un peso notevole nell’interpretazione deweyana, sia continentale che statunitense. Contrariamente a tale lettura si intende mostrare come Dewey, nel corso della sua opera, concepì il pensare come un’attività che sfugge largamente all’analisi consapevole – e in tal senso Dewey ha chiaramente precorso il tema dell’assenza di controllo che il soggetto ha sul suo proprio pensiero. Ciò conduce ad un’interpretazione del sé (“self”, nell’originale deweyano) che smantella il soggetto ego-logico cartesiano, per proporne uno di ben altro tipo: un soggetto come funzione costantemente emergente dall’esperienza. A partire da tale quadro teorico l’educazione viene tematizzata non tanto come analisi, direzione e controllo dell’esperienza, ma come creazione di nuova, imprevedibile esperienza. In Dewey l’educazione risulta non soltanto fondata su, ma anche – e più significativamente - diretta verso l’incertezza.

Stochastic ODEs and PDEs for interacting multi-type populations
Creators: name: Kliem, Sandra Martina
Publisher: name: University of British Columbia
Year: 2009

description: This thesis consists of the manuscripts of three research papers studying stochastic ODEs (ordinary differential equations) and PDEs (partial differential equations) that arise in biological models of interacting multi-type populations. In the first paper I prove uniqueness of the martingale problem for a degenerate SDE (stochastic differential equation) modelling a catalytic branching network. This work is an extension of a paper by Dawson and Perkins to arbitrary networks. The proof is based upon the semigroup perturbation method of Stroock and Varadhan. In the proof estimates on the corresponding semigroup are given in terms of weighted Hölder norms, which are equivalent to a semigroup norm in this generalized setting. An explicit representation of the semigroup is found and estimates using cluster decomposition techniques are derived. In the second paper I investigate the long-term behaviour of a special class of the SDEs considered above, involving catalytic branching and mutation between types. I analyse the behaviour of the overall sum of masses and the relative distribution of types in the limit using stochastic analysis. For the latter existence, uniqueness and convergence to a stationary distribution are proved by the reasoning of Dawson, Greven, den Hollander, Sun and Swart. One-dimensional diffusion theory allows for a complete analysis of the two-dimensional case. In the third paper I show that one can construct a sequence of rescaled perturbations of voter processes in d=1 whose approximate densities are tight. This is an extension of the results of Mueller and Tribe for the voter model. We combine critical long-range and fixed kernel interactions in the perturbations. In the long-range case, the approximate densities converge to a continuous density solving a class of SPDEs (stochastic PDEs). For integrable initial conditions, weak uniqueness of the limiting SPDE is shown by a Girsanov theorem. A special case includes a class of stochastic spatial competing species models in mathematical ecology. Tightness is established via a Kolmogorov tightness criterion. Here, estimates on the moments of small increments for the approximate densities are derived via an approximate martingale problem and Green's function representation.
Optimization by Smoothed Bandpass Calibration in Radio Spectroscopy

description: We have developed the Smoothed Bandpass Calibration (SBC) method and the best suitable scan pattern to optimize radio spectroscopic observations. Adequate spectral smoothing is applied to the spectrum toward OFF-source blank sky adjacent to a target source direction for the purpose of bandpass correction. Because the smoothing process reduces noise, the integration time for OFF-source scans can be reduced keeping the signal-to-noise ratio. Since the smoothing is not applied to ON-source scans, the spectral resolution for line features is kept. An optimal smoothing window is determined by bandpass flatness evaluated by Spectral Allan Variance (SAV). An efficient scan pattern is designed to the OFF-source scans within the bandpass stability timescale estimated by Time-based Allan Variance (TAV). We have tested the SBC using the digital spectrometer, VESPA, on the VERA Iriki station. For the targeted noise level of 5e-4 as a ratio to the system noise, the optimal smoothing window was 32 - 60 ch in the whole bandwidth of 1024 ch, and the optimal scan pattern was designed as a sequence of 70-s ON + 10-s OFF scan pairs. The noise level with the SBC was reduced by a factor of 1.74 compared with the conventional method. The total telescope time to achieve the goal with the SBC was 400 s, which was 1/3 of 1200 s required by the conventional way. Improvement in telescope time efficiency with the SBC was calculated as 3x, 2x and 1.3x for single-beam, dual-beam, and on-the-fly (OTF) scans, respectively. The SBC works to optimize scan patterns for observations from now, and also works to improve signal-to-noise ratios of archival data if ON- and OFF-source spectra are individually recorded, though the efficiency depends on the spectral stability of the receiving system.

description: In the present work we investigate the dielectric relaxation effects and charge trapping characteristics of HfO2 /Dy2O3 gate stacks grown on Ge substrates. The MOS devices have been subjected to constant voltage stress (CVS) conditions at accumulation and show relaxation effects in the whole range of applied stress voltages. Applied voltage polarities as well as thickness dependence of the relaxation effects have been investigated. Charge trapping is negligible at low stress fields while at higher fields (>4MV/cm) it becomes significant. In addition, we give experimental evidence that in tandem with the dielectric relaxation effect another mechanism- the so-called Maxwell-Wagner instability- is present and affects the transient current during the application of a CVS pulse. This instability is also found to be field dependent thus resulting in a trapped charge which is negative at low stress fields but changes to positive at higher fields.

description: Il corpo costituisce lo snodo fondamentale di ogni sapere. Il sapere è sempre un sapere del corpo. La relazione educativa è una relazione fra corpi. Le parole hanno un corpo, la scrittura ha un corpo, la lingua è un atto motorio. Nonostante tutto ciò, la dimensione corporea dell’educare risulta ancora poco tematizzata dalla riflessione pedagogica. Rifacendosi alla prospettiva inaugurata dalla pedagogia del corpo, il saggio intende riflettere sugli aspetti costitutivi di una visione corporea dei processi formativi, sviluppando la propria riflessione intorno al concetto di “postura”, per estenderne il significato, metaforicamente e non solo, ben oltre gli angusti spazi semantici cui il paradigma biomeccanico l’ha a lungo relegata. Una riflessione che intreccia conoscenze e consapevolezze interdisciplinari, per provare a svelare come nel gesto (del toccare, del vedere, dell’ascoltare, della voce) risieda molto di più del senso dell’educare di quanto riduttivamente si tenda a riconoscergli.

description: Perfect Cooper pair splitting is proposed, based on crossed Andreev reflection (CAR) in a p-type semiconductor - superconductor - n-type semiconductor (pSn) junction. The ideal splitting is caused by the energy filtering that is enforced by the bandstructure of the electrodes. The pSn junction is modeled by the Bogoliubov-de Gennes equations and an extension of the Blonder-Tinkham-Klapwijk theory beyond the Andreev approximation. Despite a large momentum mismatch, the CAR current is predicted to be large. The proposed straightforward experimental design and the 100% degree of pureness of the nonlocal current open the way to pSn structures as high quality sources of entanglement.

description: Die Arbeit untersucht Techniken für Komfortapplikationen in automobilen Ad-hoc-Netzen, die eine Verbreitung von (Verkehrs-)informationen über große Entfernungen ermöglichen. Ausgestattet mit einem selbstorganisierenden Funksystem bilden die Fahrzeuge in ihrer lokalen Umgebung spontan ein drahtloses Netzwerk. Den Schwerpunkt der Untersuchungen bilden zwei Fragestellungen, die für den Einsatz eines solchen Netzwerkes von zentraler Bedeutung sind: die Kommunikation bei geringen Ausstattungsgraden sowie die Vermeidung von Überlastsituationen bei stärkerer Verbreitung des Systems.
description: The thesis investigates techniques for comfort applications in Vehicular Ad Hoc Networks (VANETs) that disseminate (traffic) information in a large area. Equipped with a self-organizing wireless communication system, the vehicles form a local ad hoc network for information exchange. The thesis focuses on two key challenges for the application of VANET technologies: 1) communication in the phase of market introduction where only a low number of vehicles is equipped with the communication system and 2) avoidance of overload when a larger market penetration is achieved.

description: The present paper introduces the objectives and the design of the project “Governance of Educational Trajectories in Europe” (GOETE) and it presents some findings emerging from a case study conducted in one of the cities involved in the project, Bologna.
GOETE project analyzed how educational trajectories of children and young people between the end of primary education and the beginning of post-compulsory routes are regulated in eight different EU-member states: Finland, France, Germany, Italy, Netherlands, Poland, Slovenia and the UK.
The research assesses the outcomes of education, taking into account the effects of social inequalities, changes in the governance of education in terms of lifelong learning, knowledge societies and transnational educational spaces. “Life course” perspective provides an interactive understanding of educational processes and addresses the interplay between the institutionalization of individual lives and subjective biographies.

description: The Plateau de Bure Interferometer has been used to map the continuum emission at 3.4 mm and 1.1 mm together with the J=1->0 and J=3->2 lines of HCN and HCO+ towards the binary star GV Tau. The 3.4 mm observations did not resolve the binary components and the HCN J=1->0 and HCO+ J=1->0 line emissions trace the circumbinary disk and the flattened envelope. However, the 1.1 mm observations resolved the individual disks of GV Tau N and GV Tau S and allowed us to study their chemistry. We detected the HCN 3->2 line only towards the individual disk of GV Tau N, and the emission of the HCO+ 3->2 line towards GV Tau S. Simple calculations indicate that the 3->2 line of HCN is formed in the inner R<12 AU of the disk around GV Tau N where the HCN/HCO+ abundance ratio is >300. On the contrary, this ratio is <1.6 in the disk around GV Tau S. The high HCN abundance measured in GV Tau N is well explained by photo-chemical processes in the warm (>400K) and dense disk surface.

description: The Astropy Project is a community effort to develop a single core package for Astronomy in Python and foster interoperability between Python Astronomy packages, and is one of the largest open-source collaborations in Astronomy. In this talk I present an overview of the project, provide an update on the latest status of the core package, which saw the v1.1 release late last year, and discuss our plans for the coming year. In addition, I describe the "affiliated packages": Python packages that use Astropy and are associated with the project, but are not actually a part of the core library itself. I also briefly talk about the infrastructural tools we provide for these packages.

description: A new scaling is derived that yields a Reynolds number independent profile for all components of the Reynolds stress in the near-wall region of wall bounded flows, including channel, pipe and boundary layer flows. The scaling demonstrates the important role played by the wall shear stress fluctuations and how the large eddies determine the Reynolds number dependence of the near-wall turbulence behavior.

description: La computación analógica ha estado recuperando relevancia en los últimos años. Las Field-Programmable Analog Arrays (FPAAs) son dispositivos equivalentes a las Field-Programmable Gate Arrays, pero dentro del dominio analógico y de señal mixta. Con el objetivo de incrementar la cantidad de recursos analógicos, en este artículo se va a proponer el diseño y construcción de un clúster de 40 FPAAs. Como caso de uso, se ha implementado una red neuronal analógica de tipo feedforward 19-8-6-4 sobre el propio clúster. Con la ayuda de técnicas software basadas en la DCT, la red neuronal es capaz de clasificar imágenes de 28x28 píxeles del popular dataset MNIST. Los resultados obtenidos muestran que la red analógica puede obtener resultados similares a los de la red software de referencia y de mismas características.
The application of cranberry in the production and quality of fresh dairy products
Creators: name: Tomiuk, Stephen
Publisher: name: University of British Columbia

description: The antioxidant activity of an ethanol extract prepared from cranberries was investigated using the oxygen radical absorbance capacity (ORAC) assay, as well as in a model food emulsion representative of dairy-based emulsions. The cranberry extract exhibited 348.31 ± 33.45 Trolox equivalents (TE)/g in the hydrophilic ORAC assay. In the model food emulsion consisting of 25% lipid stabilized by sodium caseinate, the extract was readily incorporated at the homogenization step until a pH of 5.6 was attained without causing emulsion destabilization. Under thermal conditions (50ºC), the lag phase prior to propagation of conjugated dienes (CD) in all cranberry emulsions at pH 5.6 was significantly extended relative to untreated controls (P < 0.05). The formation of secondary lipid oxidation products (hexanal and pentanal) in sunflower oil emulsions became significantly reduced (P < 0.05), but only after 64 hours of incubation. In contrast, the development of hexanal and pentanal in butterfat emulsions were significantly reduced (P < 0.05) over the entire incubation period. Increasing the level of cranberry extract in all emulsions beyond a final pH of 5.6 had an adverse effect on emulsion stability, and this was met with a drop in oxidative protection. The acidity of the cranberry extract made it well-suited for use in a fresh cream cheese product, which requires the production of acid during manufacture. The cranberry extract was homogenized into a cream cheese premix consisting of milk and cream until a pH of 5.6 was reached. Cheese produced from 1.18 g extract/100 g premix had a light pink color that remained stable over 50 days of storage at 4ºC. The cheese curd was found to retain over 98% of phenolics from the extract after separation of the whey. The level of CD and the peroxide value in the final product were significantly lower (P < 0.05) as compared to the untreated control cream cheese, after two weeks of storage at 4ºC. This research shows for the first time that a cranberry extract rich in bioactives can provide color and flavor to fresh dairy products while also acting as a useful preservation agent.

description: We present the first public code for semi-analytical calculation of the gamma-ray flux astrophysical J-factor from dark matter annihilation/decay in the Galaxy, including dark matter substructures. The core of the code is the calculation of the line of sight integral of the dark matter density squared (for annihilations) or density (for decaying dark matter). The code can be used in three modes: i) to draw skymaps from the Galactic smooth component and/or the substructure contributions, ii) to calculate the flux from a specific halo (that is not the Galactic halo, e.g. dwarf spheroidal galaxies) or iii) to perform simple statistical operations from a list of allowed DM profiles for a given object. Extragalactic contributions and other tracers of DM annihilation (e.g. positrons, antiprotons) will be included in a second release.
