description: Ekonomik kazanç amacıyla güdülen faaliyetlerin, bireysel çabaların ötesine geçerek şirketleşmeye ve sonrasında kurumsallaşmaya başlamasından itibaren, bu faaliyetlerin sürdürülebilir hale getirilmesi, doğrudan ya da dolaylı olarak faaliyet sürecine etkide bulunan daha fazla kesimlerin memnun edilmesi ve bunların daha çok ve daha verimli katkı vermelerinin teşvik edilmesi için faaliyet sürecinin iyileştirilmesine yönelik çabalar da süregelmiştir. Bu çabaların sonucunda kurumsal yönetim felsefesi ortaya çıkmıştır. Kurumsal yönetim adillik, şeffaflık, hesap verebilirlik ve sorumluluk olmak üzere dört temel ilke üzerine bina edilmiştir. Bu temel ilkeler soyut olduğundan pratiğe yansımalarının belirlenmesi ihtiyacı ortaya çıkmıştır. Bununla birlikte, kurumsal yönetim konusunda herkese uyacak kuralların belirlenmesinin mümkün olmaması nedeniyle, bu dört temel ilke sonrasında gerekli belirlemelerin yapılması ülkelerin kendilerine bırakılmıştır. Ancak yine de OECD tarafından rehber olmaları açısından 1999 yılında kurumsal yönetim ilkeleri adı altında bir takım ilkeler açıklanmış ve son olarak bu ilkeler 2015 yılında güncellenmiştir. Benzer şekilde Türkiye’de de kurumsal yönetim ilkeleri SPK tarafından açıklanmıştır. Bu çalışmada, Kurumsal yönetimin temel ilkelerinden adillik, şeffaflık, hesap verebilirlik ve sorumluluğun OECD ve SPK tarafından açıklanan kurumsal yönetim ilkeleri bağlamında uygulamaya yansımaları konusuna değinilmektedir.

description: We study the dissipative thermodynamics of vortex lines in layered superconductors within a simple string model in the dilute limit of negligible vortex interactions and compute the specific heat $C_v$ in presence of arbitrary dissipation. The interplay of dissipation, inertia and elasticity is shown to control the qualitative thermodynamical behavior and their relative amount determines two very distinct regimes for the specific heat. In the dissipation dominated case we find a behavior $C_v \sim \sqrt{T}$ for a large interval of temperature below $T_c$.

description: Interconnecting well-functioning, scalable stationary qubits and photonic qubits could substantially advance quantum communication applications and serve to link future quantum processors. Here, we present two protocols for transferring the state of a photonic qubit to a single-spin and to a two-spin qubit hosted in gate-defined quantum dots (GDQD). Both protocols are based on using a localized exciton as intermediary between the photonic and the spin qubit. We use effective Hamiltonian models to describe the hybrid systems formed by the the exciton and the GDQDs and apply simple but realistic noise models to analyze the viability of the proposed protocols. Using realistic parameters, we find that the protocols can be completed with a success probability ranging between 85-97%.

description: SDSS J2232-0806 (the 'Big Dipper') has been identified as a 'slow-blue nuclear hypervariable': a galaxy with no previously known active nucleus, blue colours and large-amplitude brightness evolution occurring on a timescale of years. Subsequent observations have shown that this source does indeed contain an active galactic nucleus (AGN). Our optical photometric and spectroscopic monitoring campaign has recorded one major dimming event (and subsequent rise) over a period of around four years; there is also evidence of previous events consistent with this in archival data recorded over the last twenty years. Here we report an analysis of the eleven optical spectra obtained to date and we assemble a multiwavelength data set including infrared, ultraviolet and X-ray observations. We find that an intrinsic change in the luminosity is the most favoured explanation of the observations, based on a comparison of continuum and line variability and the apparent lagged response of the hot dust. This source, along with several other recently-discovered 'changing-look' objects, demonstrate that AGN can exhibit large-amplitude luminosity changes on timescales much shorter than those predicted by standard thin accretion disc models.

Κατά τη διάρκεια της έρευνας παρουσιάσαμε αναλυτικά τα βασικότερα ζητήματα τα οποία ήταν: α) οι μετακινήσεις της έδρας της Εκκλησίας της Κωνσταντινούπολης, β) οι κτηριακές μεταβολές των πατριαρχικών ναών, και γ) η διαχείριση των κτισμάτων και των εκκλησιαστικών κειμηλίων που διασώθηκαν μέχρι τις ημέρες μας. Στη συνέχεια διαπιστώσαμε ότι, παρόλο που στη βυζαντινή αυτοκρατορία υπήρχε θρησκευτική ελευθερία, οι Πατριάρχες - όντας αδύναμοι ορισμένες φορές - ήταν φειδωλοί στο να λαμβάνουν πρωτοβουλίες για την ανοικοδόμηση ναών και τη φιλοτέχνηση / διαχείριση ψηφιδωτών παραστάσεων και άλλων ιερών αντικειμένων. Αντίθετα, κατά τους χρόνους της οθωμανικής αυτοκρατορίας και παρόλη την απουσία κρατικού μηχανισμού, ο οποίος συχνά κατέστρεφε τα εκκλησιαστικά κειμήλια, οι Πατριάρχες είχαν περισσότερη ελευθερία κινήσεων, ώστε να μεριμνούν οι ίδιοι για τους εκκλησιαστικούς χώρους και τη διαχείριση των κειμηλίων, ανάλογα με την ευσυνειδησία που διέκρινε τον καθένα από αυτούς.
description: The purpose of this work was to examine historically and architecturally the Patriarchal Temple and House of the Church of Constantinople, as well as the management of its relics, from its foundation (38 AD) until the definitive establishment of the seat of the Ecumenical Patriarchate in Phanar (1600). During the research, we presented in detail the main issues: a) the movements of the headquarters of the Church of Constantinople, b) the structural changes of the patriarchal churches, and c) the management of the buildings and church relics that are safe until today. We then found that although there was religious freedom in the Byzantine Empire, the Patriarchs - being weak at times - were sparing in taking initiatives to rebuild temples and the art/management of mosaics and other sacred objects. On the contrary, during the times of the Ottoman Empire and despite the absence of a state apparatus, which often destroyed ecclesiastical relics, the Patriarchs had more freedom of movement so that they could take care of the ecclesiastical spaces and the management of the relics themselves, depending on the conscientiousness that distinguished each of them.
Temperature dependence of the resistivity in the double-exchange model

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: The resistivity around the ferromagnetic transition temperature in the double exchange model is studied by the Schwinger boson approach. The spatial spin correlation responsible for scattering of conduction electrons are taken into account by adopting the memory function formalism. Although the correlation shows a peak lower than the transition temperature, the resistivity in the ferromagnetic state monotonically increases with increasing temperature due to a variation of the electronic state of the conduction electron. In the paramagnetic state, the resistivity is dominated by the short range correlation of scattering and is almost independent of the temperature. It is attributed to a cancellation between the nearest-neighbor spin correlation, the fermion bandwidth, and the fermion kinetic energy. This result implies the importance of the temperature dependence of the electronic states of the conduction electron as well as the localized spin states in both ferromagnetic and paramagnetic phases.

Path Calculations and Option Pricing
Creators: name: Wang, Min
Publisher: name: University of Leicester
Year: 2020
Subjects: Uncategorized

description: The thesis is worked in the areas of the intersection of probability, combinatorics and analytical combinatoric. The research is motivated from the need of producing new methodologies and financial models in global market resulted from the lesson of 2007-2009 global financial market and a quantum tool called Feynman path integral method which has been applied to model path-dependent option pricing model by Hao and Utev. Path calculation method deal with models by analysing each possible individual asset price paths which broaden the methodology of modelling financial market and can solve some unusual or complex models which is difficult to model by using non path-dependent calculation method. My research has focused on developing combinatorial structure and path calculation methods and then apply them to model individual share price path and calculate option prices. The share price can be modelled as a path with a given share price changes and the expiry date. We have applied Flajolet symbolic method, generating functions and path calculation method to model a set of typical finite restricted share price paths with restriction not allowing k consecutive down steps and derived a calculation of option prices in the model. Besides, applying the Flajolet symbolic method, we constructed a relationship between individual share price and generating function, analysed the transformed share price paths via different operations on generating functions. In addition, we applied path calculation method to solve winning probability in the classical gambler ruin problem which contributes the same result as the solution solved by establishing the recurrence equation method. Furthermore, we have solved a different gambler's ruin problem using the path calculation method which cannot be solved by the recurrence equation method. Counting paths with combinatoric can be studied from two ways, one way is to label and the other is computation. Labelling is a part of representation of objects. We have developed a graphical theoretical construction of individual share price path via general binary trees and matroid. In addition, We have developed a method to solve some kinds of pattern avoiding path counting combinatorial problem by modifying certain probability methods. Two working papers including modelling of paths via matroids and counting via Markov-type technique is now being produced.
Nanostructured flexible radiation sensors

Publisher: name: Università degli studi di Trento

description: Flexible scintillating radiation detectors have gained increasing attention in the scientific community in the last decade. They represent a fast and easy way for monitoring the impinging radiation in real time and acquire the dose released in medical treatments, like cancer radio- or proton-therapy sessions. Flexible linear-chain polysiloxane detectors offer the possibility to overcome geometrical limitations, they possess superior optical transparency and flexibility, and can be obtained with contained production costs and times, making them highly competitive with respect to traditional single-crystals and plastics. Unlike phenyl-containing siloxanes, linear polysiloxanes does not show direct interaction with the impinging radiation, therefore they can be used just as matrices for hosting luminescent materials, such as nanocrystals or nanopowders. Quantum dots (QDs) are nanocrystals showing quantum confinement effects, with an incredible light yield, a tunable emission wavelength and a fast decay lifetime. For these reasons, they are worth being incorporated in siloxane-based scintillators as primary dyes, without the need of complex ternary systems. Part of this thesis analyzes the effects of ionizing radiation on the luminescence and temporal response of QD-loaded polysiloxanes for radiation detection and monitoring, with special focus on real-time measurements under proton beam. Another possibility is to embed luminescent nanopowders, such as zinc oxide (ZnO) and reduced zinc oxide (ZnO:Zn). The Zn-rich form shows a remarked green luminescence, with increasing light yield as a function of the reduction degree, i.e. zinc content. In view of the above, this thesis reports the advances on polysiloxanes loaded with ZnO and ZnO:Zn phosphors. The core of the thesis is devoted to the progresses in ZnO production and treatment for the realization of multi-layered flexible scintillators. A special focus is putted on a novel production route based on atmospheric pressure plasma (APPJ), that allows for the co-deposition of ZnO-loaded plasma polymers and for the doping via liquid precursor solution.
Microbial enzymes for hair removal: an integrated biotechnological approach for application in the leather tanning industry
Creators: name: Demattè, Elisa
Publisher: name: Università degli studi di Trento
Year: 2021

description: ABSTRACT Microbial enzymes have been used for decades in a number of processes in the industrial, biomedical, environmental, and agro-food sectors. The dehairing phase of the leather tanning process is currently mediated by sulphur/sulphides chemicals, requiring expensive and complex procedures for water depollution and increasing safety risks for workers. This project is aimed at the development of a microbially-driven process for hair removal based on secreted enzymes. The first phase of the project consisted in the isolation of microorganisms naturally present on raw hides (cow skin) and displaying dehairing ability. A collection of 52 pure bacterial isolates was first screened for proteolytic activity (25 positive isolates) and then for their ability to grow on minimal media (10 positive isolates). The genome of these 10 isolates was sequenced and the supernatants containing secreted enzymes (and potential other metabolites) were tested for enzymatic activity and dehairing capacity at a laboratory scale. The secretome analysis reported the presence of more than 200 secreted proteins for each isolate and showed an increase in the release of hydrolytic enzymes during growth on minimal media. Further selection among the 10 isolates was based on proteomic analysis, pilot scale dehairing tests and yields after the downstream process The 4 isolates, selected on the base of the unhairing ability, secretome analysis and downstream yields, were subjected to further characterization to choose the most promising for the desired activity. Isolate 1Dm15, selected for the dehairing ability demonstrated at pilot scale, was grown in bioreactor and once the parameters were defined a scale-up of the process was performed. In conclusion, in this work we identified a Bacillus sp. strain able to grow on minimal media and secrete a pool of enzymes active in the dehairing of hides. This microbially driven process shows promising application in the industrial practice substituting the use of reducing agents.

The two condensates are created with a well-defined relative phase and complete spatial overlap. In subsequent evolution they undergo complex relative motions which tend to preserve the total density profile. the motions quickly damp out, leaving the condensates in a steady state with a nonnegligible (and adjustable) overlap region.

description: The automobile industry has set the demand regarding Powder Metallurgy (PM) parts for decades, since this near-net shape technology is a cost-effective manufacturing process allying good mechanical properties with dimensional and geometrical precision. Aiming at the future of the electric automobiles high production and demand, many changes are on the way to guarantee the competitiveness of PM against other manufacturing process. The high costs of alloying elements such as Ni and Cu, the changes in health and safety regulations as well as light weighting of components are the topics of major importance in the field of PM and focus of main R&D around the globe. The use of high temperature sintering and different alloying elements are possible solutions to overcome properties obtained by using Ni as an alloying element sintered at conventional temperatures. Materials with Cr, Mo and Si were investigated using high temperature sintering (1180°C and 1250°) in comparison to traditionally high Ni materials sintered at conventional temperature (1120°C). The dimensional stability, geometrical precision, density, and microstructure of ring-shaped specimens were studied by using a coordinate measuring machine (CMM) and the effect of HTS on the mechanical properties were estimated through the fraction of the load bearing section. The effect of HTS on the dimensional precision and geometrical stability was later investigated in real parts manufactured by industrial partners through an EPMA Club Project. The 4%Ni material sintered at 1120°C was also compared to Ni-less/Ni-free materials sintered at 1250°C using tensile testing, impact testing, and hardness. The use of HTS to improve the mechanical properties without impairing the dimensional and geometrical stability was confirmed in parts with both low and high complexity designs. This project sets the blueprint for future material developments using HTS as manufacturing process.

description: We study the statistical properties of energy spectra of two-dimensional quasiperiodic tight-binding models. We demonstrate that the nearest-neighbor level spacing distributions of these non-random systems are well described by random matrix theory. Properly taking into account the symmetries of models defined on various finite approximants of quasiperiodic tilings, we find that the underlying universal level-spacing distribution is given by the Wigner-Dyson distribution of the Gaussian orthogonal random matrix ensemble. Our data allow us to see the differences between the Wigner surmise and the exact level-spacing distribution. In particular, our result differs from the critical level-spacing distribution computed at the metal-insulator transition in the three-dimensional Anderson model of disorder.

description: While the acoustic properties of solid foams have been abundantly characterized, sound propagation in liquid foams remains poorly understood. Recent studies have investigated the transmission of ultrasound through three-dimensional polydisperse liquid foams (Pierre et al., 2013, 2014, 2017). However, further progress requires to characterize the acoustic response of better controlled foam structures. In this work, we study experimentally the transmission of ultrasounds through a single layer of monodisperse bubbles generated by microfluidics techniques. In such a material, we show that the sound velocity is only sensitive to the gas phase. Nevertheless, the structure of the liquid network has to be taken into account through a transfer parameter analogous to the one in a layer of porous material. Finally, we observe that the attenuation cannot be explained by thermal dissipation alone, but is compatible with viscous dissipation in the gas pores of the monolayer.

description: We consider the construction of operator bases for massless, relativistic quantum field theories, and show this is equivalent to obtaining the harmonic modes of a physical manifold (the kinematic Grassmannian), upon which observables have support. This enables us to recast the approach of effective field theory (EFT) through the lens of harmonic analysis. We explicitly construct harmonics corresponding to low mass dimension EFT operators.

description: The contemporary cities are facing affected by three factors that are changing our lifestyle: the economic and relative social crisis getting worse by the pandemic, the technological revolution and the climate changes effects. In this framework, this thesis investigates the adaptive urban planning as a part of DICAM - Trento Urban Transformation Research Programme, which started in 2017 to provide scientific support for the Trento general urban plan review. This doctoral research aims to demonstrate how the open, adaptive and metabolic plan can respond to city demands by means of Collaborative urban Transformations: the processes that go beyond the dichotomous relationship between the strategical approach and the tactical one. The thesis output is an Open Toolbox made of strategies, tactics and devices to catalyses the challenges, goals and actions of adaptive urban plan, as the Trento Leaf Plan proposed by the TUT research group. The final Manifesto has been proposed to test and implement in other contexts the new planning approach capable to activating the ecological transition, as an adaptive, multi-scalar and interdisciplinary process that leads towards a city more ECO, ACCOGLIENTE, ACCESSIBILE, SMART and BELLA.

description: Abstract

The use of reliable ecological information to support evidence-based management decisions for critically threatened species is often limited by data availability and local ecological knowledge (LCK) is increasingly regarded as a significant source of knowledge for conservation. The Indian Pangolin, Manis Crassicaudata, is considered endangered even though it plays a vital role in the food chain because it eats termites and other insects.  This study in Pakistan aims to assess the critically endangered Indian pangolin's ecological role, population status, and illegal trade level using local community knowledge. We conducted a questionnaire-based survey research and collected the most recent data of Indian pangolin with 200 respondents across different locations of four districts (Jhelum, Chakwal, Rawalpindi, and Islamabad) between March 2020- April 2022 in the Potohar region of Punjab province, Pakistan. The survey aimed to determine whether LCK can provide innovative insights for pangolin conservation. The illegal trade of pangolins was reported across all four districts: Jhelum (73%, n=41), Chakwal (61.81%, n=55), Islamabad (>78.5%, n=42), and Rawalpindi (48.5%, n=62). As insectivorous animals, Indian pangolins serve as pest controllers and are beneficial for the ecosystem by protecting crops and forests. However, the illegal trade continues, with pangolin scales and other body parts, such as nails and flesh, being used by local communities and traded outside the country. Worldwide fund for nature plays an important role to stop the illegal trading of Indian Pangolin. This study stresses the need for detailed surveys to create conservation plans based on local community knowledge.

description: In this article, we consider a small rigid body moving in a viscous fluid filling the whole plane. We assume that the diameter of the rigid body goes to 0, that the initial velocity has bounded energy and that the density of the rigid body goes to infinity. We prove that the rigid body has no influence on the limit equation by showing convergence of the solutions towards a solution of the Navier-Stokes equations in the full plane.

Image Animation Using Deep Learning

description: Recently media content generation, particularly image and video, using deep learning gained a lot of attention in the research community. One of the main reasons for that is the surge of the interactions in the social networks, that draw a lot of people without specialized backgrounds into the media industry. This raises the interest in the tolls for simplifying the production of the media content, such as images and videos. Another potential avenue for deep learning methods is a simplification of the content generation for the traditional media, especially creation of movies, visual effects for which require significant human efforts. One of the most promising directions, in deep learning based content production, is image animation, e.g. generation of videos based on the known appearance and the movement. While the GANs and other generative models have shown great progress in the generation of the random images and videos, photorealistic quality in image animation is still not achieved. In this work we made a step into this direction by stating the task of the image animation and proposing several new methods for solving it. In the image animation we are given a single source image and a driving video and are asked to produce a video where an object from the source image moves like an object from the driving video. Prior to adapting deep learning techniques for image animation we investigate an ability of these to work on simpler, but related task, e.g. pose-guided generation. In this task we are given source image and target pose and asked to generate a person from the source image in the target pose. We identify the main flaw of the current image2image architectures and propose a new architecture, based on deformable skip connection, to address this. We used these insides to create methods for image animation. To this end we propose an architecture called Monkey-Net that is based on the keypoints learned in the unsupervised way. However only the keypoints are not able to represent all the possible variations in the pose movement, to this end we propose to extend the keypoints representation with local affine transformation around these keypoints in the First Order Model. Finally we propose a new better way of estimation of the affine transformations using Principal Component Analysis (PCA).

Preserving the hand-painted films of Margaret Tait

Subjects: P303 - Film studies

description: In this paper I discuss a small amount of the work of Margaret Tait. The Introduction offers a personal discussion on the profession of Archiving which I revisit in my conclusion. Section One provides a general overview of Margaret Taitâ€™s life and influences. This brief biographical information serves as a background for the more substantial technical discussion in Section Two.Though I do enjoy Taitâ€™s films and find her work compelling, I should emphasise that I am not concerned with providing a critique of Margaret Taitâ€™s films nor a complete overview of her life and work. I deem that to be a quite different paper and one I am not interested in writing. My main purpose here is to trace the technical developments Tait made in her filmmaking and show how an understanding of her practices can help in the restoration and preservation of her films. I hope this paper also demonstrates that the biographical is inseparable from the technical and for the Archivist, these two approaches to Taitâ€™s work are again inseparable from the ethical and philosophical dimensions of the idea of permanence.
Ground-state properties of rutile: electron-correlation effects

description: Electron-correlation effects on cohesive energy, lattice constant and bulk compressibility of rutile are calculated using an ab-initio scheme. A competition between the two groups of partially covalent Ti-O bonds is the reason that the correlation energy does not change linearly with deviations from the equilibrium geometry, but is dominated by quadratic terms instead. As a consequence, the Hartree-Fock lattice constants are close to the experimental ones, while the compressibility is strongly renormalized by electronic correlations.

description: In this lecture we present some interesting issues that arise when the dynamics of the charge carriers in the CuO$_2$ planes of the high temperature superconductors is considered. Based on the qualitative picture of doping, set by experiments and some previous calculations, we consider the strength of various inter and intra-cell charge transfer susceptibilities, the question of Coulomb screening and charge collective modes. The starting point is the usual p-d model extended by the long range Coulomb (LRC) interaction. Within this model it is possible to examine the case in which the LRC forces frustrate the electronic phase separation, the instability which is present in the model without an LRC interaction. While the static dielectric function in such systems is negative down to arbitrarily small wavevectors, the system is not unstable. We consider the dominant electronic charge susceptibilities and possible consequences for the lattice properties.

description: We calculate the zero-temperature phase diagram of the disordered Bose-Hubbard model in one dimension using the density matrix renormalization group. For integer filling the Mott insulator is always separated from the superfluid by a Bose glass phase. There is a reentrance of the Bose glass both as a function of the repulsive interaction and of disorder. At half-filling where no Mott insulator exists, the superfluid density has a maximum where the kinetic and repulsive energies are about the same. Superfluidity is suppressed both for small and very strong repulsion but is always monotonic in disorder.

description: We examine the motion of charged particles in gravitational and electro-magnetic background fields. We study in particular the deviation of world lines, describing the relative acceleration between particles on different space-time trajectories. Two special cases of background fields are considered in detail: (a) pp-waves, a combination of gravitational and electro-magnetic polarized plane waves travelling in the same direction; (b) the Reissner-Nordstrøm solution. We perform a non-trivial check by computing the precession of the periastron for a charged particle in the Reissner-Nordstrøm geometry both directly by solving the geodesic equation, and using the world-line deviation equation. The results agree to the order of approximation considered.

description: Entanglement is a critical resource used in many current quantum information schemes. As such entanglement has been extensively studied in two qubit systems and its entanglement nature has been exhibited by violations of the Bell inequality. Can the amount of violation of the Bell inequality be used to quantify the degree of entanglement. What do Bell inequalities indicate about the nature of entanglement?
