description: L’idea generale da cui parte l’attività di analisi e di ricerca della tesi è che l’identità non sia un dato acquisito ma un processo aperto. Processo che è portato avanti dall’interazione tra riconoscimento sociale del proprio ruolo lavorativo e rappresentazione soggettiva di sé. La categoria di lavoratori che è stata scelta è quella degli informatori scientifici del farmaco, in virtù del fatto che la loro identificazione con il ruolo professionale e la complessa costruzione identitaria è stata duramente messa alla prova negli ultimi anni a seguito di una profonda crisi che ha coinvolto la categoria. Per far fronte a questa crisi nel 2008 è stato creato un dispositivo, che ha visto il coinvolgimento di aziende, lavoratori, agenzie per il lavoro e organizzazioni sindacali, allo scopo di ricollocare il personale degli informatori scientifici del farmaco coinvolto in crisi e/o ristrutturazioni aziendali.

description: Let $K$ be a convex body in ${\mathbb R}^n$, and let $Π_1({\mathbb R}^n)$ be the space of polynomials in $n$ variables of degree at most $1$. Given an $(n+1)$-element set $Y\subset K$ in general position, we let $P_Y$ denote the Lagrange interpolation projector $P_Y: C(K)\to Π_1({\mathbb R}^n)$ with nodes in $Y$. In this paper, we study upper and lower bounds for the norm of the optimal Lagrange interpolation projector, i.e., the projector with minimal operator norm where the minimum is taken over all $(n+1)$-element sets of interpolation nodes in $K$. We denote this minimal norm by $θ_n(K)$. Our main result, Theorem 5.2, provides an explicit lower bound for the constant $θ_n(K)$ for an arbitrary convex body $K\subset{\mathbb R}^n$ and an arbitrary $n\ge 1$. We prove that $θ_n(K)\ge χ_n^{-1}\left({{\rm vol}(K)}/{{\rm simp}(K)}\right)$ where $χ_n$ is the Legendre polynomial of degree $n$ and ${\rm simp}(K)$ is the maximum volume of a simplex contained in $K$. The proof of this result relies on a geometric characterization of the Legendre polynomials in terms of the volumes of certain convex polyhedra. More specifically, we show that for every $γ\ge 1$ the volume of the set $\left\{x=(x_1,...,x_n)\in{\mathbb R}^n : \sum |x_j| +\left|1- \sum x_j\right|\leγ\right\}$ is equal to ${χ_n(γ)}/{n!}$. If $K$ is an $n$-dimensional ball, this approach leads us to the equivalence $θ_n(K) \asymp\sqrt{n}$ which is complemented by the exact formula for $θ_n(K)$. If $K$ is an $n$-dimensional cube, we obtain explicit efficient formulae for upper and lower bounds of the constant $θ_n(K)$; moreover, for small $n$, these estimates enable us to compute the exact values of this constant.

description: Image classifiers should be used with caution in the real world. Performance evaluated on a validation set may not reflect performance in the real world. In particular, classifiers may perform well for conditions that are frequently encountered during training, but poorly for other infrequent conditions. In this study, we hypothesize that recent advances in text-to-image generative models make them valuable for benchmarking computer vision models such as image classifiers: they can generate images conditioned by textual prompts that cause classifier failures, allowing failure conditions to be described with textual attributes. However, their generation cost becomes an issue when a large number of synthetic images need to be generated, which is the case when many different attribute combinations need to be tested. We propose an image classifier benchmarking method as an iterative process that alternates image generation, classifier evaluation, and attribute selection. This method efficiently explores the attributes that ultimately lead to poor behavior detection.

description: The climate change projections by the Intergovernmental Panel on Climate Change (IPCC) envisage an increase in extreme precipitation events with riverine and flash floods throughout the globe. The maps depicting the flood-affected area produced in near real-time can help the decision-makers for effective disaster response management and damage assessment. Therefore, different modules are developed for flood disaster management using Synthetic Aperture Radar (SAR) remote sensing which helps the research and scientific communities. Module 1 describes the theoretical background for SAR based flood mapping as well as various methods and techniques for rapid flood mapping.

description: Patient hand-off and triage are two fundamental problems in health care. Often doctors must painstakingly summarize complex findings to efficiently communicate with specialists and quickly make decisions on which patients have the most urgent cases. In pursuit of these challenges, we present (1) a model with state-of-art radiology report summarization performance using (2) a novel method for augmenting medical data, and (3) an analysis of the model limitations and radiology knowledge gain. We also provide a data processing pipeline for future models developed on the the MIMIC CXR dataset. Our best performing model was a fine-tuned BERT-to-BERT encoder-decoder with 58.75/100 ROUGE-L F1, which outperformed specialized checkpoints with more sophisticated attention mechanisms. We investigate these aspects in this work.

description: The thesis explores ways to formalize the legal knowledge concerning the public procurement domain by means of ontological patterns suitable, on one hand, to support awarding authorities in conducting procurement procedures and, on the other hand, to help citizens and economic operators in accessing procurement's notices and data. 

Such an investigation on the making up of  conceptual models for the public procurement domain, in turn, inspires and motivates a reflection on the role of legal ontologies nowadays, as in the past, retracing the steps of the ``ontological legal thinking'' from Roman Law up to now. I try, at the same time, to forecast the impact, in terms of benefits, challenges and critical issues, of the application of computational models of Law in future e-Governance scenarios.
Admittance and noise in an electrically driven nano-structure: Interplay between quantum coherence and statistics

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We investigate the interplay between the quantum coherence and statistics in electrically driven nano-structures. We obtain expression for the admittance and the current noise for a driven nano-capacitor in terms of the Floquet scattering matrix and derive a non-equilibrium fluctuation-dissipation relation. As an interplay between the quantum phase coherence and the many-body correlation, the admittance has peak values whenever the noise power shows a step as a function of near-by gate voltage. Our theory is demonstrated by calculating the admittance and noise of driven double quantum dots.
Absorbing boundary conditions for dynamical many-body quantum systems

description: In numerical studies of the dynamics of unbound quantum mechanical systems, absorbing boundary conditions are frequently applied. Although this certainly provides a useful tool in facilitating the description of the system, its applications to systems consisting of more than one particle is problematic. This is due to the fact that all information about the system is lost upon absorption of one particle; a formalism based solely on the Scrh{ö}dinger equation is not able to describe the remainder of the system as particles are lost. Here we demonstrate how the dynamics of a quantum system with a given number of identical fermions may be described in a manner which allows for particle loss. A consistent formalism which incorporates the evolution of sub-systems with a reduced number of particles is constructed through the Lindblad equation. Specifically, the transition from an $N$-particle system to an $(N-1)$-particle system due to a complex absorbing potential is achieved by relating the Lindblad operators to annihilation operators. The method allows for a straight forward interpretation of how many constituent particles have left the system after interaction. We illustrate the formalism using one-dimensional two-particle model problems.

description: We report an element-specific investigation of electronic and magnetic properties of the graphene/Ni(111) system. Using magnetic circular dichroism, the occurrence of an induced magnetic moment of the carbon atoms in the graphene layer aligned parallel to the Ni 3d magnetization is observed. We attribute this magnetic moment to the strong hybridization between C $π$ and Ni 3d valence band states. The net magnetic moment of carbon in the graphene layer is estimated to be in the range of $0.05-0.1 μ_B$ per atom.

description: Single dish observations of AGB star L$_2$ Pup have revealed exceptionally low mass loss rate and expansion velocity, challenging interpretations in terms of standard wind models. Recent VLT and ALMA observations have drawn a detailed picture of the circumstellar envelope within $\sim$20 au from the centre of the star: a nearly edge-on rotating disc of gas and dust, probably hosting a planetary companion near the star. However, these observations provide no direct information on the wind escaping the gravity of the star. The present article uses ALMA observations of the $^{12,13}$CO(3-2), $^{29}$SiO(8-7), $^{12}$CO(2-1) and $^{28}$SiO(5-4) line emissions to shed new light on this issue. It shows the apparent normality of L$_2$ Pup in terms of the formation of the nascent wind, with important line broadening within 4 au from the centre of the star, but no evidence for a wind flowing along the disc axis. At larger distances, up to some 200 au from the centre of the star, the wind morpho-kinematics is dominated by a disc, or equatorial enhancement, expanding isotropically and radially with a velocity not exceeding some 5 km s$^{-1}$ , inclined in the north-west/south-east direction with respect to the plane of the sky. In addition, outflows of lower density are observed on both sides of the disc, covering large solid angles about the disc axis, contributing about half the flux of the disc. Such morphology is at strong variance with the expectation of a pair of back-to-back outflows collimated by the central gas-and-dust disc.

description: The growth in electricity consumption in Iran necessitates rapid development in power plant construction. Like many other countries, most of Iran's power plants rely on fossil fuels. Over the past decade, approximately 94% of electricity was generated by thermal power plants, with about 6% from renewable sources like hydro-power. This study aims to offer a comprehensive overview of Iran's electricity generation industry over a span of 42 years, highlighting its evolutionary trends. Data regarding installed power generation capacity and electricity generation from 1967 to 2008 has been compiled. Additionally, total pollutant emissions and emissions per unit of electricity generation for different types of power plants were calculated using emission factors. The analysis presents the patterns of electricity generation and emissions over this period. The results underscore the importance of promoting the use of renewable energy sources, increasing the contribution of combined cycle power plants as a preferable form of thermal power, and prioritizing the use of natural gas to mitigate emissions.
Scalar quantum kinetic theory for spin-1/2 particles: mean field theory

description: Starting from the Pauli Hamiltonian operator, we derive a scalar quantum kinetic equations for spin-1/2 systems. Here the regular Wigner two-state matrix is replaced by a scalar distribution function in extended phase space. Apart from being a formulation of principal interest, such scalar quantum kinetic equation makes the comparison to classical kinetic theory straightforward, and lends itself naturally to currently available numerical Vlasov and Boltzmann schemes. Moreover, while the quasi-distribution is a Wigner function in regular phase space, it is given by a Q-function in spin space. As such, nonlinear and dynamical quantum plasma problems are readily handled. Moreover, the issue of gauge invariance is treated. Applications (e.g. ultra-dense laser compressed targets and their diagnostics), possible extensions, and future improvements of the presented quantum statistical model are discussed.

description: We argue that the A_4 symmetry as required by three flavors of fermions may well-embed in the SU(3)_C X SU(3)_L X U(1)_X gauge model. The new neutral fermion singlets as introduced in a canonical seesaw mechanism can be combined with the standard model lepton doublets to perform SU(3)_L triplets. Various leptoscalar multiplets such as singlets, doublets, and triplets as played in the models of A_4 are unified in single SU(3)_L antisextets. As a result, naturally light neutrinos with various kinds of mass hierarchies are obtained as a combination of type I and type II seesaw contributions. The observed neutrino mixing pattern in terms of the Harrison-Perkins-Scott proposal is obtained by enforcing of the A_4 group. The quark masses and Cabibbo-Kobayashi-Maskawa mixing matrix are also discussed. By virtue of very heavy antisextets the nature of the vacuum alignments of scalar fields can be given.

description: Three-tangle for the rank-three mixture composed of Greenberger-Horne-Zeilinger, W and flipped W states is analytically calculated. The optimal decompositions in the full range of parameter space are constructed by making use of the convex-roof extension. We also provide an analytical technique, which determines whether or not an arbitrary rank-3 state has vanishing three-tangle. This technique is developed by making use of the Bloch sphere S^8 of the qutrit system. The Coffman-Kundu-Wootters inequality is discussed by computing one-tangle and concurrences. It is shown that the one-tangle is always larger than the sum of squared concurrences and three-tangle. The physical implication of three-tangle is briefly discussed.

description: The observed late-type WC Wolf-Rayet stars (WC7-9) with low luminosity below $\rm \log L/L_{\odot} < 5.4$ in the HR diagram cannot be reproduced satisfactorily by the evolutionary track of single stars. The mass transfer due to Roche lobe overflow drastically modifies the internal structure and surface compositions of two components. Therefore, binaries provide a very promising evolutionary channel to produce these WC stars.

description: The European Union (EU) has been pursuing new cyber security policies in recent years. This paper presents a short reflection of four such policies. The focus is on potential incoherency, meaning a lack of integration, divergence between the member states, institutional dysfunction, and other related problems that should be at least partially avoidable by sound policy-making. According to the results, the four policies have substantially increased the complexity of the EU's cyber security framework. In addition, there are potential problems with trust, divergence between industry sectors and different technologies, bureaucratic conflicts, and technical issues, among other things. With these insights, the paper not only contributes to the study of EU policies but also advances the understanding of cyber security policies in general.

Futteraufnahme und Futtereffizienz bei hochleistenden Milchkühen korrekt bewerten

Year: 2021

description: Kurz vor der Kalbung und mit beginnender Laktation befindet sich die hochleistende Milchkuh (individuell unterschiedlich lange) in einer negativen Energiebilanz (NEB). In dieser Phase sind Milchkühe in der Lage, Körperfett- und Körperproteinreserven für die Milchbildung heranzuziehen. Diese Eigenschaft ist keineswegs pathologisch, sondern eine genetisch determinierte Strategie, mit deren Hilfe die Stoffwechselleistung laktierender Muttertiere gesteigert werden kann. Die Strategie bleibt jedoch nicht ohne Risiko für die laktierende Hochleistungskuh, da sich leicht auch Störungen - vor allem des Lipidstoffwechsels - einstellen können. Die Energiebilanz (EB) einer Kuh kann geschätzt werden, indem sie aus der Energieaufnahme und -abgabe berechnet wird. Da in der Praxis sehr oft verlässliche Kenntnisse über die Futteraufnahme fehlen, finden solche Indikatoren wie die Änderung der Körpermasse (∆KM), die Änderung des Körperzustands (∆BCS), die Milchfettsäuren (FA) oder das Fett: Protein-Verhältnis (FPR) zunehmendes Interesse. Von besonderem Interesse sind vor allem leicht zugängliche Indikatoren, die mit wenig Aufwand routinemäßig erfasst ewerden können. In der vorliegenden Arbeit werden solche Kenngrößen aufgezeigt und bewertet. Schlüsselwörter: Milchkühe, postpartale Energiebilanz (EB), Milchbestandteile, Milchfettsäuren, Tierschutz

description: A theory of double affine and special double affine bundles, i.e. differential manifolds with two compatible (special) affine bundle structures, is developed as an affine counterpart of the theory of double vector bundles. The motivation and basic examples come from Analytical Mechanics, where double affine bundles have been recognized as a proper geometrical tool in a frame-independent description of many important systems. Different approaches to the (special) double affine bundles are compared and carefully studied together with the problems of double vector bundle models and hulls, duality, and relations to associated phase spaces, contact structures, and other canonical constructions.

description: Zusammenfassung • Die Züchtung hochleistender Milchkühe erfordert die Sicherstellung einer hohen Futteraufnahme; speziell in der Frühlaktation; • Eine Zuchtstrategie mit hoher Bewertung der Futteraufnahme in der Frühlaktation sowie gleichzeitig negativer Bewertung sehr hoher Einsatzleistungen stellt sicher, dass eine weitere Ausdehnung der negativen Energiebilanz (NEB) in künftigen Generationen vermieden wird. Eine derartige Zuchttierauslese reduziert allerdings den möglichen Gesamtzuchtfortschritt für die Milchleistung deutlich; • gezielte genetisch-züchterische Maßnahmen können managementbedingte Fütterungsfehler auf betrieblicher Ebene nicht ausgleichen.

The fusion rules are then used to determine projective covers. This allows us also to write down a candidate for a modular invariant partition function. Our results demonstrate that recent work on the ${\cal W}_{2,3}$ model generalises naturally to arbitrary (p,q).

Inertial measurement units (IMUs) have been developed to objectively measure upper limb range of motion (ROM) and shoulder function. In this work, we propose an IMU-based shoulder functional task assessment with kinematic parameters (e.g., smoothness, power, speed, and duration) in FS patients and analyze the functional performance on complete shoulder tasks and subtasks. Twenty FS patients and twenty healthy subjects were recruited in this study. Five shoulder functional tasks are performed by participants, such as washing hair (WH), washing upper back (WUB), washing lower back (WLB), placing an object on a high shelf (POH), and removing an object from back pocket (ROP). The results demonstrate that the used smoothness features can reflect the differences of movement fluency between FS patients and healthy controls (p < 0.05 and effect size > 0.8). Moreover, features of subtasks provided subtle information related to clinical conditions that have not been revealed in features of a complete task, especially the defined subtask 1 and 2 of each task.

description: In these lectures I review the status of gravity from the point of view of the gauge principle and renormalization, the main tools in the toolbox of theoretical particle physics. In the first lecture I start from the old question "in what sense is gravity a gauge theory?" I will reformulate the theory of gravity in a general kinematical setting which highlights the presence of two Goldstone boson-like fields, and the occurrence of a gravitational Higgs phenomenon. The fact that in General Relativity the connection is a derived quantity appears to be a low energy consequence of this Higgs phenomenon. From here it is simple to see how to embed the group of local frame transformations and a Yang Mills group into a larger unifying group, and how the distinction between these groups, and the corresponding interactions, derives from the VEV of an order parameter. I will describe in some detail the fermionic sector of a realistic "GraviGUT" with SO(3,1)xSO(10) \subset SO(3,11). In the second lecture I will discuss the possibility that the renormalization group flow of gravity has a fixed point with a finite number of attractive directions. This would make the theory well behaved in the ultraviolet, and predictive, in spite of being perturbatively nonrenormalizable. There is by now a significant amount of evidence that this may be the case. There are thus reasons to believe that quantum field theory may eventually prove sufficient to explain the mysteries of gravity.

On shortest products for nonnegative matrix mortality

description: Given a finite set of matrices with integer entries, the matrix mortality problem asks if there exists a product of these matrices equal to the zero matrix. We consider a special case of this problem where all entries of the matrices are nonnegative. This case is equivalent to the NFA mortality problem, which, given an NFA, asks for a word $w$ such that the image of every state under $w$ is the empty set. The size of the alphabet of the NFA is then equal to the number of matrices in the set. We study the length of shortest such words depending on the size of the alphabet. We show that for an NFA with $n$ states this length can be at least $2^n - 1$ for an alphabet of size $n$, $2^{(n - 4)/2}$ for an alphabet of size $3$ and $2^{(n - 2)/3}$ for an alphabet of size $2$. We also discuss further open problems related to mortality of NFAs and DFAs.

Repeated measurements and random scattering in quantum walks

Year: 2024
Subjects: subject: Quantum Physics (quant-ph)

description: We study the effect of random scattering in quantum walks on a finite graph and compare it with the effect of repeated measurements. To this end, a constructive approach is employed by introducing a localized and a delocalized basis for the underlying Hilbert space. This enables us to design Hamiltonians whose eigenvectors are either localized or delocalized. By presenting some specific examples we demonstrate that the localization of eigenvectors restricts the transition probabilities on the graph and leads to dark states in the monitored evolution. We conclude that repeated measurements as well as random scattering provide efficient tools for controlling quantum walks.

Futteraufnahme und Futtereffizienz bei hochleistenden Milchkühen korrekt bewerten

Publisher: name: Berichte über Landwirtschaft - Zeitschrift für Agrarpolitik und Landwirtschaft
Year: 2021

description: Die Milcherzeuger haben sich bisher vorrangig auf eine Maximierung der Milchleistung je Kuh/Jahr konzentriert, da davon ausgegangen wurde (wird), dass dies den möglichen Gewinn durch eine systematische Reduzierung der Gesamtkosten maximiert. Das eingesetzte Futter ist dabei in allen Produktionsssystemen eine Hauptkomponente zugehöriger variabler Kosten. Eine der hier am häufigsten interessierenden Parameter ist die Futtereffizienz (FE), die als produzierte Milchmenge im Verhältnis zur Menge verbrauchter Nährstoffe definiert werden kann. Ein kritischer Aspekt bei der Abschätzung der FE ist der Zeitraum, für den die Effizienz gemessen wird. Es zeigt sich, dass die FE im Laktationsverlauf bemerkenswert dynamisch ist. Die Tatsache, dass es demnächst möglich ist, genomische Zuchtwerte für die Futteraufnahme (FA) oder FE abzuschätzen, begründet die hohe Aktualität der Thematik. Hier stellt sich zusätzlich die Frage, wie am besten zugehörige weitere Informationen (z.B. die Veränderung der Körpermasse der Milchkühe in der Frühlaktation) im Zuchtziel berücksichtigt werden sollten, ohne dass es zu unerwünschten Reaktionen in der Nachkommenschaft kommt.

description: The classical Ising chain is the paradigm for the non-existence of phase transitions in 1D systems and was solved by Ernst Ising one hundred years ago. More recently, a decorated two leg Ising ladder has received interest for the curious thermodynamics that resemble a phase transition; a sharp peak in the specific heat at low, but finite temperature. We use this model to reveal a bifurcation in the correlation lengths due to a crossing of the sub-leading eigenvalues of the transfer matrix, which results in two distinct length scales necessary to describe to the decay of correlations. We discuss this phenomenon in the context of the geometric frustration in the model. We also provide additional results to aid in the understanding of the curious thermodynamics of the model through a study of the magnetic susceptibilities.

title: Improving flood prediction using data assimilation
Creators: name: Cooper, Elizabeth S.
Publisher: name: University of Reading

description: River flooding is a costly problem worldwide. Timely, accurate prediction of the behaviour of flood water is vital in helping people make preparations. Mathematical hydrodynamic models can predict the behaviour of flood water given information about inputs such as river bathymetry, local topography, inflows, and values for model parameters. Uncertainty in these inputs leads to inaccuracies in model predictions; data assimilation can be used to improve forecasts by combining model predictions with observational information, taking into account uncertainties in both. In this thesis we investigate ways to maximize the impact of observational information from satellite-based synthetic aperture (SAR) instruments in data assimilation for inundation forecasting. We show in synthetic twin experiments using an ensemble transform Kalman filter that using joint state-parameter data assimilation techniques to correct the model channel friction parameter as well as water levels provides a significant, long lasting benefit to the model forecast. We show that errors in the channel friction parameter and inflow are interdependent. We propose a novel observation operator that allows direct use of measured SAR backscatter values, potentially allowing the use of many more observations per SAR image. We test our new observation operator in synthetic experiments, showing that we can successfully update inundation forecasts and the value of the model channel friction parameter using our new approach. We show that different observation operator approaches can generate significantly different updates to model forecasts and illustrate the physical mechanisms responsible. Lastly, we use our new observation operator to assimilate backscatter values from real SAR images, showing that our new approach can be used to improve inundation forecasts in a real case study. Improved understanding of the physical mechanisms by which updates are generated by different observation operators provides insights into improving the observation impact of SAR data.

description: We explore alternative formulations of the analogy between viable Horndeski gravity and Eckart's first-order thermodynamics. We single out a class of identifications for the effective stress-energy tensor of the scalar field fluid that, upon performing the imperfect fluid decomposition, yields constitutive relations that can be mapped onto Eckart's theory. We then investigate how different couplings to Einstein's gravity, at the level of the field equations, can affect the thermodynamic formalism overall. Last, we specialize the discussion to the case of ``traditional'' scalar-tensor theories and identify a specific choice of the coupling function that leads to a significant simplification of the formalism.

description: We have observed the 70 $μ$m dark infrared dark cloud (IRDC) G14.492-00.139 in the N$_2$D$^+$ $J$=3--2, DCO$^+$ $J$=3--2, DCN $J$=3--2, and C$^{18}$O $J$=2--1 lines, using the Atacama Large Millimeter/submillimeter Array (ALMA) as part of the ALMA Survey of 70 $μ$m Dark High-mass Clumps in Early Stages (ASHES). We find that the spatial distribution is different among the observed emission from the deuterated molecular lines. The N$_2$D$^+$ emission traces relatively quiescent regions, while both the DCO$^+$ and DCN emission emanates mainly from regions with signs of active star-formation. In addition, the DCO$^+$/N$_2$D$^+$ ratio is found to be lower in several dense cores than in starless cores embedded in low-mass star-forming regions. By comparing the observational results with chemical model calculations, we discuss the origin of the low DCO$^+$/N$_2$D$^+$ ratio in this IRDC clump. The low DCO$^+$/N$_2$D$^+$ ratio can be explained if the temperature of the dense cores is in the range between the sublimation temperature of N$_2$ ($\sim$20 K) and CO ($\sim$25 K). The results suggest that the dense cores in G14.492-00.139 are warmer and denser than the dense cores in low-mass star-forming regions.
