description: In this article we consider the ergodic risk-sensitive control problem for a large class of multidimensional controlled diffusions on the whole space. We study the minimization and maximization problems under either a blanket stability hypothesis, or a near-monotone assumption on the running cost. We establish the convergence of the policy improvement algorithm for these models. We also present a more general result concerning the region of attraction of the equilibrium of the algorithm.

description: The quantum states of flux qubit is suggested to observe with the help of a new device, the superconducting differential double contour interferometer (DDCI). The flux qubit and the superconducting quantum interference device (DC-SQUID) are connected in the DDCI through the phase of the wave function rather than through magnetic flux. The critical current of DC-SQUID should change to the maximum value at the change of the flux qubit state thanks to this phase coupling. A large jump in the critical current and voltage enables to observe continuously the change in time the state of the flux qubit. This observation can have fundamental importance for the investigation of the superposition of macroscopic quantum states.

description: The variance reduction class of algorithms including the representative ones, SVRG and SARAH, have well documented merits for empirical risk minimization problems. However, they require grid search to tune parameters (step size and the number of iterations per inner loop) for optimal performance. This work introduces `almost tune-free' SVRG and SARAH schemes equipped with i) Barzilai-Borwein (BB) step sizes; ii) averaging; and, iii) the inner loop length adjusted to the BB step sizes. In particular, SVRG, SARAH, and their BB variants are first reexamined through an `estimate sequence' lens to enable new averaging methods that tighten their convergence rates theoretically, and improve their performance empirically when the step size or the inner loop length is chosen large. Then a simple yet effective means to adjust the number of iterations per inner loop is developed to enhance the merits of the proposed averaging schemes and BB step sizes. Numerical tests corroborate the proposed methods.
XMM-Newton Reflection Grating Spectrometer Observations of the Prototypical Starburst Galaxy M82

description: We present results from XMM-Newton Reflection Grating Spectrometer observations of the prototypical starburst galaxy M82. These high resolution spectra represent the best X-ray spectra to date of a starburst galaxy. A complex array of lines from species over a wide range of temperatures is seen, the most prominent being due to Lyman-alpha emission from abundant low Z elements such as N, O, Ne, Mg and Si. Emission lines from Helium-like charge states of the same elements are also seen in emission, as are strong lines from the entire Fe-L series. Further, the OVII line complex is resolved and is seen to be consistent with gas in collisional ionization equilibrium. Spectral fitting indicates emission from a large mass of gas with a differential emission measure over a range of temperatures (from 0.2 keV to 1.6 keV, peaking at 0.7 keV), and evidence for super-solar abundances of several elements is indicated. Spatial analysis of the data indicates that low energy emission is more extended to the south and east of the nucleus than to the north and west. Higher energy emission is far more centrally concentrated.

Exotic signature of dynamical quantum phase transition in the time evolution of engineered initial state

description: Dynamical phase transition in quantum many body systems is usually studied by taking it in the ground state and then quenching a parameter to a new value. We investigate here the dynamics when one performs the time evolution of a generic state and observe that the rate function related to the Loschmidt echo shows non-analytic behavior of two types, one related, and the other unrelated, to the appearance of a quantum phase transition. Specifically, we consider a quantum Ising chain in an initial configuration which is a generic superposition of the eigenstates, and follow its dynamics under the transverse Ising Hamiltonian with constant field. Depending on the the configuration of the initial state, some singularities appear in the rate function which do not correspond to the equilibrium phase transition of the Hamiltonian. However another class of singularity is found having connection with the quantum critical point. Some features of the singularities of the rate function have been derived analytically and it is observed that the occupancy of quasiparticle eigenstates plays the key role in triggering the non-analyticities.

description: This paper introduces a new negotiating agent model for automated negotiation. We focus on applications without time pressure with multidi-mensional negotiation on both continuous and discrete domains. The agent bidding strategy relies on Monte Carlo Tree Search, which is a trendy method since it has been used with success on games with high branching factor such as Go. It also exploits opponent modeling techniques thanks to Gaussian process regression and Bayesian learning. Evaluation is done by confronting the existing agents that are able to negotiate in such context: Random Walker, Tit-for-tat and Nice Tit-for-Tat. None of those agents succeeds in beating our agent. Also, the modular and adaptive nature of our approach is a huge advantage when it comes to optimize it in specific applicative contexts.
Bygone Modernity: Re-imagining Italian opera in Milan, New York and Buenos Aires, 1887-1914

description: This dissertation provides a detailed study of Italian operatic transfer between Milan, New York and Buenos Aires in the decades around 1900. It investigates how ideas and practices of Italian opera were defined in these two key American cities, offering an explicitly transnational perspective on Italian operatic culture. In so doing, it also considers the reciprocal impacts of transatlantic movement on operatic life in Milan during a period of burgeoning New World cultural and economic dominance. This study comprises five broadly chronological case studies. Chapter One addresses the first transatlantic productions of Verdi’s Otello (1887), in the context both of an emerging Italian culture industry and of rapid American urbanisation. Chapter Two considers the double-bill of Mascagni’s Cavalleria rusticana (1890) and Leoncavallo’s Pagliacci (1892), examining their pairing and performance history in Buenos Aires and New York in the light of mass Italian immigration as well as in terms of contemporary constructions of the “popular”. Chapter Three turns to Puccini’s Madama Butterfly (1904), examining the opera in relation to Puccini’s 1907 New York tour and the American operatic gramophone industry. Chapter Four examines the 1906 Milan Exposition, investigating its musical activities – particularly a revival at La Scala of Verdi’s La traviata (1853) – against contemporary fascination with Argentina. Chapter Five considers constructions of an Italian-American operatic canon in the early 1910s, focusing on the Argentine world premiere of Mascagni’s Isabeau (1911) and the New York reception of Montemezzi’s L’amore dei tre re (1913). Overall, this dissertation seeks to demonstrate the complex position of Italian opera in these two American cities at a time of rapid demographic and urban change, while highlighting the importance of American perceptions in shaping Milanese (and more broadly Italian) operatic identities. If opera served as agent both of modernisation and of cultural continuity in the New World, commentators in New York and Buenos Aires frequently cast Italy itself as bygone: a conception that fuelled Milan’s own drive towards modernity, while challenging familiar ideas of opera as a quintessentially Italian artform.

Application of Helmholtz-Hodge decomposition to the study of certain vector fields

Subjects: subject: Dynamical Systems (math.DS)
subject: FOS: Mathematics

description: Smooth vector fields on $\mathbb{R}^n$ can be decomposed into the sum of a gradient vector field and divergence-free (solenoidal) vector field under suitable hypotheses. This is called the Helmholtz-Hodge decomposition (HHD), which has been applied to analyze the topological features of vector fields. In this study, we apply the HHD to study certain types of vector fields. In particular, we investigate the existence of strictly orthogonal HHDs, which assure an effective analysis. The first object of the study is linear vector fields. We demonstrate that a strictly orthogonal HHD for a vector field of the form $\textbf{F}(\textbf{x}) = A \textbf{x}$ can be obtained by solving an algebraic Riccati equation. Subsequently, a method to explicitly construct a Lyapunov function is established. In particular, if A is normal, there exists an easy solution to this equation. Next, we study planar vector fields. In this case, the HHD yields a complex potential, which is a generalization of the notion in hydrodynamics with the same name. We demonstrate the convenience of the complex potential formalism by analyzing vector fields given by homogeneous quadratic polynomials.

description: We show that the inclusion of irrelevant terms in the Hamiltonian describing tunneling between edge states in the fractional quantum Hall effect can lead to a variety of non perturbative behaviors in intermediate energy regimes, and, in particular, affect crucially the determination of charge through shot noise measurements. We show, for instance, that certain combinations of relevant and irrelevant terms can lead to an effective measured charge $νe$ in the strong backscattering limit and an effective measured charge $e$ in the weak backscattering limit, in sharp contrast with standard perturbative expectations. This provides a possible scenario to explain the experimental observations by Heiblum and coworkers, which are so far not understood.

description: We analyse the electronic and optical properties of graphene quantum dots (GQD) using accurate \textit{ab initio} many-body $GW$ and Bethe-Salpeter calculations. We show that most pristine GQD, including structures with irregular shapes, are characterized by dark low energy singlet excitations that quench fluorescence. We rationalizqe this property by exploiting the chiral symmetry of the low energy electronic states in graphene. Edge \textit{sp}$^3$ functionalization is shown to efficiently brighten these low lying excitations by distorting the \textit{sp}$^2$ backbone planar symmetry. Such findings reveal an original indirect scenario for the influence of functionalization on the photoluminescence properties.

description: This paper addresses the complex production planning and control (PPC) challenges in food supply chains. The study illustrates how food producers' traditional make-to-stock (MTS) approach is not well suited to meet the trends of increasing product variety, higher demand uncertainty, increasing sales of fresh food products and more demanding customers. The paper proposes a framework for differentiated PPC that combines MTS with make-to-order (MTO). The framework matches products with the most appropriate PPC approaches and buffering techniques depending on market and product characteristics. The core idea is to achieve more volume flexibility in the production system by exploiting favourable product and market characteristics (high demand predictability, long customer order lead time allowances and low product perishability). A case study is used to demonstrate how the framework can enable food producers to achieve efficiency in production, inventory and PPC processes – and simultaneously be responsive to market requirements.
An asymmetric explosion mechanism may explain the diversity of Si II line widths in Type Ia supernovae

description: Near maximum brightness, the spectra of Type Ia supernovae (SNe Ia) present typical absorption features of Silicon II observed at roughly 6100A and 5750A. The 2-D distribution of the pseudo-equivalent widths (pEWs) of these features is a useful tool for classifying SNe Ia spectra (Branch plot). Comparing the observed distribution of SNe on the Branch plot to results of simulated explosion models, we find that 1-D models fail to cover most of the distribution. In contrast, we find that TARDIS radiative transfer simulations of the WD head-on collision models along different lines of sight almost fully cover the distribution. We use several simplified approaches to explain this result. We perform order-of-magnitude analysis and model the opacity of the Si lines using LTE and NLTE approximations. Introducing a simple toy model of spectral feature formation, we show that the pEW is a good tracer for the extent of the absorption region in the ejecta. Using radiative transfer simulations of synthetic SNe ejecta, we reproduce the observed Branch plot distribution by varying the luminosity of the SN and the Si density profile of the ejecta. We deduce that the success of the collision model in covering the Branch plot is a result of its asymmetry, which allows for a significant range of Si density profiles along different viewing angles, uncorrelated with a range of $^{56}$Ni yields that cover the observed range of SNe Ia luminosity. We use our results to explain the shape and boundaries of the Branch plot distribution.

description: The paper will present an approach for an incremental solution development that is based on the usage of the currently developed Internet based FIspace business collaboration platform. Key element is the clear segmentation of infrastructures that are either internal or external to the collaborating business entity in the food network. On the one hand, the approach enables to differentiate between specific centralised as well as decentralised ways for data storage and hosting of IT based functionalities. The selection of specific data exchange protocols and data models is facilitated. On the other hand, the supported solution design and subsequent development is focusing on reusable “software Apps” that can be used on their own and are incorporating a clear added value for the business actors. It will be outlined on how to push the development and introduction of Apps that do not require basic changes of the existing infrastructure. The paper will present an example that is based on the development of a set of Apps for the exchange of product quality related information in food networks, specifically addressing fresh fruits and vegetables. It combines workflow support for data exchange from farm to retail as well as to provide quality feedback information to facilitate the business process improvement. Finally, the latest status of the FIspace platform development will be outlined. Key features and potential ways for “real users and software developers” in using the FIspace platform that is initiated by science and industry will be outlined.

description: The OECD (1997) conceives a national innovation system (NIS) as “technology and information among people, enterprises and institutions are key to the innovative process” (p. 7). Innovation is conceived as the result of complex set of relationships among actors in the system, which includes companies, universities and research centres. In actual knowledge-based economies, industry-links are essential for economic development and progress (Ahrweiler et al., 2011). They are essential for building up networks of relationships that are necessary for any firm to innovate (Freeman 1987, 1992). In particular, many influential studies have identified the links between firm innovation and competitive advantage at the national level (Porter, 1990). Lundvall (1992) describes characteristics of NIS, emphasizing the importance or learning and how small countries, with limited public budgets and few large corporations, have selected areas of innovation strength and are able to absorb knowledge and innovations from elsewhere (Cooke et al., 1997). Thus, the vision of a NSI is just beyond the technological advances, “but is more broadly on the factors influencing national technological capabilities” (Nelson & Rosenberg, 1993: 4).

description: The general purpose of the paper is to investigate consumer's attitude towards high quality agri-food products. The research analyses PDO labelled products packaged by law in the production area. Within the same area, the Producers' Group imposes the use of the Consortium label as a quality sign. As consequence, collective labels as well are find on a product packaging, by virtue of the fact that not only they graphically and symbolically represent quality, but they also inform customers about the properties of a specific PDO good. Moreover, on the same package other labels (industrial and private ones) are displayed on the same package. At this purpose, the research analysis of the customers' perception of such particular labels combination focusing the case of the ready-sliced Parma ham. The analysis gives the opportunity of evaluating, from an economic perspective, aspects related to the use of multi-labelling strategy.

description: The horticulture and propagation materials sector has been designated as one of the so-called top sectors in which the Netherlands excels globally and that are a government priority. The top sector approach for further innovation is based on public-private partnerships (PPPs) in which businesses, knowledge institutes and the (national) government are working closely together towards a common vision and action plans (the 'golden triangle'). This paper introduces the Digital Greenport Holland (Dutch: Tuinbouw Digitaal) and its research and innovation programme ‘a Smarter Greenport’. Digital Greenport Holland is the PPP of the horticultural top sector that focuses on digital information management. The business involvement consists of the collaboration between three active industry associations for chain information, i.e. Frug I Com (fruit and vegetables), Floricode (flowers and plants) and EDIbulb (flower bulbs). The activities focus on four main themes: E-standards, E-information-integration, E-business-to-government and E-competence. The programme ‘a Smarter Greenport’ has currently conducted eight projects on these themes.

Zadoyan et al., Chem. Phys. 266, 323 (2001)]. We give a concrete example of how this can be accomplished through an illustrative algorithm that solves the Deutsch-Jozsa problem. We use realistic molecular parameters to recognize that, as the problem size expands, shaped pulses must be tailored to maintain fidelity of the algorithm.

Narain transform for spectral deformations of random matrix models

Year: 2019
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: We start from applying the general idea of spectral projection (suggested by Olshanski and Borodin and advocated by Tao) to the complex Wishart model. Combining the ideas of spectral projection with the insights from quantum mechanics we derive in an effortless way all spectral properties of the complex Wishart model: first, the Marcenko-Pastur distribution interpreted as a Bohr-Sommerfeld quantization condition for the hydrogen atom; second, hard (Bessel), soft (Airy) and bulk (sine) microscopic kernels from properly rescaled radial Schrödinger equation for the hydrogen atom. Then, generalizing the ideas based on Schrödinger equation to the case when Hamiltonian is non-Hermitian, we propose an analogous construction for spectral projections of universal kernels built from bi-orthogonal ensembles. In particular, we demonstrate that the Narain transform is a natural extension of the Hankel transform for the products of Wishart matrices, yielding an explicit form of the universal kernel at the hard edge. We also show, how the change of variables of the {\it rescaled} kernel allows to make the link to universal kernel of Muttalib-Borodin ensemble. The proposed construction offers a simple alternative to standard methods of derivation of microscopic kernels, based e.g. on Plancherel Rotach limit of orthogonal polynomials of asymptotics in the Riemann-Hilbert problem. Finally, we speculate, that a suitable extension of the Bochner theorem for Sturm-Liouville operators may provide an additional insight into the classification of microscopic universality classes in random matrix theory.

description: In the paper, the authors considered estimation of efficiency, which measures the ability of a company to obtain the maximum output from given inputs. The comparison of results obtained by using two approaches: parametric (on the example of the SFA method, Stochastic Frontier Analysis) and non-parametric (on the example of the DEA method, Data Envelopment Analysis) has been carried out. Data from the companies of a key food processing sector in Poland, namely the milk processing sector, was used in the paper. This sector was chosen due to the large size of the sample, as well as the strategic importance and significant contribution to the production of the entire agri-food sector. Furthermore, with respect to the milk processing sector there are no comparative analyzes carried out, which justifies the need for their conduction. The analysis covered the period 2006-2011, the sample included from 103 up to 160 enterprises (depending on the analyzed year). Basing on the conducted analysis it was claimed that the integral use of the SFA and the DEA methods– combining advantages of both methods – allows preserving the analogy when comparing the results and formulating reliable conclusions.

description: “Buying local” has become one of the most important trends in food marketing. Despite widespread public attention, the influence of the “local” attribute on food prices is not well understood. We aim to begin to fill this gap in research by exploring the presence of a price premium for “local” in actual market transactions. Using scanner data on fresh packaged lettuce in the Honolulu market and hedonic modeling, we investigate consumers’ revealed preferences for the attribute. Contrary to the positive willingness to pay for local food widely reported in previous studies, we find no local premium for fresh lettuce in the Honolulu market.

description: The Rho family of small GTPases act as molecular switches in the cell and are involved in signalling pathways implicated in cytoskeletal organisation. To mediate their effects, they interact with downstream effectors. The protein kinase C-related kinase (PRK) family of serine/threonine kinases consists of three members, PRK1, PRK2 and PRK3, all of which are Rho family effectors. PRKs have three N-terminal Homology Region 1 (HR1) domains, HR1a, HR1b and HR1c. These are predicted antiparallel coiled coils which interact with the Rho proteins. While HR1a and HR1b domains have been studied in vitro, very little is known about the HR1c domain. This project aims to provide much-needed biochemical, biophysical and structural understanding of HR1 domains. The secondary structure and stability of PRK1 and PRK3 HR1 domains is outlined, followed by the identification of some HR1 domains as oligomerisation domains of their respective PRK. Analysis of the oligomeric state of the single, di- and tri-domains indicates that the three HR1 domains are not independent in solution. The NMR solution structure of the PRK1 HR1c domain is solved, highlighting the differences between this domain and other HR1 domains. The structure is then used as a tool to delineate the interactions between the three PRK1 HR1 domains. A model is created which summarises intra- and inter-molecular HR1 interactions. GTPase-HR1 interactions then expand the model by linking the HR1 oligomerisation to GTPase binding. New GTPase interactions with PRK1 and PRK3 HR1 domains are also identified, highlighting our limited knowledge about the PRKs and the subsequent studies which will need to follow.

Unlocking Generalization for Robotics via Modularity and Scale

description: How can we build generalist robot systems? Looking at fields such as vision and language, the common theme has been large scale end-to-end learning with massive, curated datasets. In robotics, on the other hand, scale alone may not be enough due to the significant multi-modality of robotics tasks, lack of easily accessible data and the safety and reliability challenges of deploying on physical hardware. Meanwhile, some of the most successfully deployed robotic systems today are inherently modular and can leverage the independent generalization capabilities of each module to perform well. Inspired by these qualities, this thesis seeks to tackle the task of building generalist robot agents by integrating these components into one: combining modularity with large scale learning for general purpose robot control. We begin by exploring these two aspects independently. The first question we consider is: how can we build modularity and hierarchy into learning systems? Our key insight is that rather than having the agent learn hierarchy and low-level control end-to-end, we can explicitly enforce modularity via planning to enable significantly more efficient and capable robot learners. Next, we come to the role of scale in building generalist robot systems. To effectively scale, neural networks require vast amounts of diverse data, expressive architec tures to fit the data and a source of supervision to generate the data. To that end, we leverage a powerful supervision source: classical planning algorithms, which can generalize broadly, but are expensive to run and require access to perfect, privileged information to perform well in practice. We use these planning algorithms to supervise large-scale policy learning in simulation to produce generalist agents. Finally, we consider how to unify modularity with large-scale policy learning to build autonomous real-world robot systems capable of performing zero-shot long-horizon manipulation. We propose to do so by tightly integrating key ingredients of modular high and mid-level planning, learned local control, procedural scene generation and large-scale policy learning for sim-to-real transfer. We demonstrate that this recipe can produce powerful results: a single, generalist agent can solve challenging long-horizon manipulation tasks in the real world, solely from text instruction.

description: Im Forschungsprojekt «Planspiel Qualität und Resilienz» wurde ein prototypisches Werkzeug entwickelt, um den Dialog zu Qualität und Resilienz im gebauten Raum zu stärken. Das analog und digital verfügbare Planspiel zielt darauf ab, zu Beginn einer Entwicklungsidee ein gemeinsames Verständnis aller Stakeholder zu schaffen und eine Position zu beziehen, welche die Grundlage für alle nachfolgenden Aushandlungsprozesse in Planung, Umsetzung, Betrieb und Transformation bildet.
Das Projekt richtet sich an Planungsteams, die sich in der Phase Null eines Bauvorhabens befinden, kann aber auch in der Aus- und Weiterbildung eingesetzt werden. Mithilfe des Spiels werden Planungsprozesse in einzelne Bausteine zerlegt und ergebnisoffen und spielerisch gestaltet. Jede:r Spieler:in schlüpft dabei in eine andere Rolle und lernt neue Perspektiven kennen. Die Idee ist, möglichst viele Interessensgruppen von Beginn an zu integrieren, ein gegenseitiges Verständnis und eine gemeinsame Sprache zu entwickeln. Indem alle Spieler:innen über ihre verschiedenen Vorstellungen von Qualität und ihre Bedürfnisse sprechen, soll der Transfer in die Praxis gelingen und ein qualitätvolles Bauprojekt entstehen.
Das Planspiel enthält Module für unterschiedliche Anwendungsfälle. Anhand eines konkreten (z.B. Neubau, Transformation) oder fiktiv gewählten Ortes werden bestehende Qualitäten gemeinsam analysiert und neue Wunschqualitäten formuliert, um anschliessend mithilfe einer Fantasiereise ihre Zukunftsfähigkeit und Resilienz festzustellen. Exemplarische Qualitäten werden vertieft und geeignete Instrumente für den Transfer der Ergebnisse aus dem Spiel in die Planung und zur nachhaltigen Qualitätssicherung bestimmt. Persönliche Erkenntnisse werden dokumentiert und gemeinsame Thesen formuliert.
Das Spiel wurde in seiner analogen und digitalen Version anhand verschiedener Prototypen in mehreren Testspielen kontinuierlich weiterentwickelt. Das Planspiel setzt allgemein geltende Nachhaltigkeitsziele wie z.B. Ressourcenschonung, Kreislaufwirtschaft, Klimaanpassung und Netto-Null als gegebene Anforderungen voraus. Für eine zielführende Diskussion kommen im Spiel konkrete Qualitätsaussagen und Massnahmen zum Einsatz, die solche Zielsetzungen ergänzen.

description: We present a smoothed particle hydrodynamic (SPH) simulation that reproduces a galaxy that is a moderate facsimile of those observed. The primary failing point of previous simulations of disk formation, namely excessive transport of angular momentum from gas to dark matter, is ameliorated by the inclusion of a supernova feedback algorithm that allows energy to persist in the model ISM for a period corresponding to the lifetime of stellar associations. The inclusion of feedback leads to a disk at a redshift $z=0.52$, with a specific angular momentum content within 10% of the value required to fit observations. An exponential fit to the disk baryon surface density gives a scale length within 17% of the theoretical value. Runs without feedback, with or without star formation, exhibit the drastic angular momentum transport observed elsewhere.
