description: Ο σκοπός της παρούσας διατριβής είναι η διερεύνηση των παραγόντων που επηρεάζουν τη συμπεριφορά του καταναλωτή ως προς το κρέας των πουλερικών και η διατύπωση προτάσεων σε επίπεδο στρατηγικής μάρκετινγκ και δημόσιας πολιτικής.Η έρευνα αυτή βασίζεται σε δεδομένα τα οποία συγκεντρώθηκαν από τη βιβλιογραφική ανασκόπηση, την ποιοτική και την ποσοτική έρευνα. Η ποιοτική έρευνα στηρίχθηκε στην πραγματοποίηση εις βάθος συνεντεύξεων σε n=22 καταναλωτές του πολεοδομικού συγκροτήματος της Θεσσαλονίκης. Η ποσοτική έρευνα πραγματοποιήθηκε με τη μέθοδο της απλής τυχαίας δειγματοληψίας σε δείγμα n=240 καταναλωτών. Για την ανάλυση των δεδομένων χρησιμοποιήθηκαν η περιγραφική στατιστική, η ανάλυση παραγόντων με Varimax περιστροφή και οι μη παραμετρική έλεγχοι Spearman ρ και Mann-Whitney U test.Τα ευρήματα δείχνουν ότι κοινωνικοδημογραφικές μεταβλητές (όπως το φύλο, η ηλικία, το μορφωτικό επίπεδο και το μηνιαίο οικογενειακό εισόδημα), συμπεριφορικές μεταβλητές (συχνότητα αγοράς, τόπος αγοράς, τρόπος αγοράς και περίσταση) και ψυχογραφικές μεταβλητές (αντίληψη ως προς την ποιότητα, ασφάλεια, κίνδυνο, τιμή, η ανάμιξη, οι στάσεις ως προς τη μέθοδο εκτροφής), επηρεάζουν τη συμπεριφορά του καταναλωτή ως προς το κρέας των πουλερικών.
description: The purpose of this work is to examine factors which affect consumer behavior towards poultry meat and to suggest solutions in strategic marketing and public policy level.The study is based on literature review, qualitative and quantitative research. The qualitative research is based on depth interviews and the sample was 22 consumers. The quantitative research is based on simple random sampling and the sample was 240 consumers. Descriptive statistics, principal component analysis (PCA) with Varimax rotation, Spearman ρ and Mann-Whitney U test were used. Findings suggest that consumers’ behavior towards poultry meat affected by socio-demographic variables (sex, age, education level, monthly family income), behavioral variables (purchasing frequency, purchasing places, purchasing ways and usage situation) and psychographic variables (perceived quality, safety, risk and price, involvement and attitudes towards raring methods).
Collisional Hardening of Compact Binaries in Globular Clusters

description: We consider essential mechanisms for orbit-shrinkage or "hardening" of compact binaries in globular clusters to the point of Roche-lobe contact and X-ray emission phase, focussing on the process of collisional hardening due to encounters between binaries and single stars in the cluster core. The interplay between this kind of hardening and that due to emission of gravitational radiation produces a characteristic scaling of the orbit-shrinkage time with the single-star binary encounter rate $γ$ in the cluster which we introduce, clarify, and explore. We investigate possible effects of this scaling on populations of X-ray binaries in globular clusters within the framework of a simple "toy" scheme for describing the evolution of pre-X-ray binaries in globular clusters. We find the expected qualitative trends sufficiently supported by data on X-ray binaries in galactic globular clusters to encourage us toward a more quantitative study.

description: Mutual information and information entropies in momentum space are proposed as measures of the non-local aspects of information. Singlet and triplet state members of the helium isoelectronic series are employed to examine Coulomb and Fermi correlation, and their manifestations, in both the position and momentum space mutual information measures. The triplet state measures exemplify that the magnitude of the spatial correlations relative to the momentum correlations, depends on, and may be controlled by the strength of the electronic correlation. Examination of one and two-electron Shannon entropies in the triplet state series yields a crossover point, which is characterized by a localized momentum density. The mutual information density in momentum space illustrates that this localization is accompanied by strong correlation at small values of $p$.

description: This paper presents an experimental evaluation on the accuracy of indoor localisation. The research was carried out as part of a European Union project targeting the creation of ICT solutions for older adult care. Current expectation is that advances in technology will supplement the human workforce required for older adult care, improve their quality of life and decrease healthcare expenditure. The proposed approach is implemented in the form of a configurable cyber-physical system that enables indoor localization and monitoring of older adults living at home or in residential buildings. Hardware consists of custom developed luminaires with sensing, communication and processing capabilities. They replace the existing lighting infrastructure, do not look out of place and are cost effective. The luminaires record the strength of a Bluetooth signal emitted by a wearable device equipped by the monitored user. The system's software server uses trilateration to calculate the person's location based on known luminaire placement and recorded signal strengths. However, multipath fading caused by the presence of walls, furniture and other objects introduces localisation errors. Our previous experiments showed that room-level accuracy can be achieved using software-based filtering for a stationary subject. Our current objective is to assess system accuracy in the context of a moving subject, and ascertain whether room-level localization is feasible in real time.

description: We present detections of numerous 10-20 micron H2O emission lines from two protoplanetary disks around the T Tauri stars AS 205A and DR Tau, obtained using the InfraRed Spectrograph on the Spitzer Space Telescope. Follow-up 3-5 micron Keck-NIRSPEC data confirm the presence of abundant water and spectrally resolve the lines. We also detect the P4.5 (2.934 micron) and P9.5 (3.179 micron) doublets of OH and 12CO/13CO v=1-0 emission in both sources. Line shapes and LTE models suggest that the emission from all three molecules originates between ~0.5 and 5 AU, and so will provide a new window for understanding the chemical environment during terrestrial planet formation. LTE models also imply significant columns of H2O and OH in the inner disk atmospheres, suggesting physical transport of volatile ices either vertically or radially; while the significant radial extent of the emission stresses the importance of a more complete understanding of non-thermal excitation processes.

description: In this paper, we aim to use the approach to the digital preservation of research data at VU Amsterdam as a case study to show the importance and benefits of organising digital preservation from a user-centric perspective. We show that awareness raising is not enough to change the existing practices, as many reasons stop individuals from reaching out to central support services despite the awareness of their existence. Instead, we strive to put the researcher at the heart of our digital preservation support services by truly listening to their needs and creating an ecosystem that supports individuals on every step of their journey and makes digital preservation a natural part of their workflow.

description: Although deep learning has achieved remarkable successes over the past years, few reports have been published about applying deep neural networks to Wireless Sensor Networks (WSNs) for image targets recognition where data, energy, computation resources are limited. In this work, a Cost-Effective Domain Generalization (CEDG) algorithm has been proposed to train an efficient network with minimum labor requirements. CEDG transfers networks from a publicly available source domain to an application-specific target domain through an automatically allocated synthetic domain. The target domain is isolated from parameters tuning and used for model selection and testing only. The target domain is significantly different from the source domain because it has new target categories and is consisted of low-quality images that are out of focus, low in resolution, low in illumination, low in photographing angle. The trained network has about 7M (ResNet-20 is about 41M) multiplications per prediction that is small enough to allow a digital signal processor chip to do real-time recognitions in our WSN. The category-level averaged error on the unseen and unbalanced target domain has been decreased by 41.12%.
Femininity and authorship : Deren, Duras and von Trotta
Creators: name: Plessis, Judith Maria
Publisher: name: University of British Columbia
Year: 2009

description: The work of Maya Deren, Marguerite Duras and Margarethe von Trotta, three filmmakers who are also authors, inhabits a space between patriarchy and polemic feminism. The result, a refocusing and re-arrangement of traditional literary and cinematic discourse, may be termed a feminine authorship. The principles of this authorship mainly derive from Laura Mulvey’s controversial but influential application of psychoanalytical theory to feminine cinema in “Visual Pleasure and Narrative Cinema” (Screen, 1975), an investigation of the “male gaze” in film. Her propositions have been further developed by critics such as Teresa de Lauretis (1980), Mary Anne Doane (1987) and Judith Mayne (1990) as well as Mulvey herself (1981). Mulvey’s approach shares with classical psychoanalysis an emphasis on the unconscious and its visual manifestations in dream and memory. Deren, Duras and von Trotta encode the latter in spatial imagery expressive of both women’s repression and their hidden resourcefulness, most frequently drawing on the gothic novel and the exotic tale. In order to accomplish their vision, the three filmmakers variously offer original interpretations of well-established modes and genres such as surrealism (Deren), the nouveau roman (Duras), and the documentary (von Trotta), but none could have done so without conceding to a number of compromises with patriarchal discourse, partly for economic, partly for ideological reasons. This thesis asserts (in contrast to Hélène Cixous, Luce Irigaray and Peggy Kamuf) that these compromises need not be read as a flaw, but contribute to a discourse in its own right. By analyzing authors from diverse cultural, social and linguistic backgrounds who, moreover, cannot be clearly categorized within the alleged dichotomy of patriarchy and feminism, this study seeks to expand the definition of feminism across national and ideological boundaries. In so doing, it may contribute to the study of other women authors and filmmakers whose views and methods have been similarly unorthodox.

We obtain the the behavior of the phase in terms of the iteration of a simple family of circle maps. When expansion of the universe is taken into account the qualitative behavior of the phase and growth number evolution is reminiscent of the behavior found in the case without expansion.

description: Using the potential model and thermodynamical quantities obtained in lattice gauge calculations, we determine the spontaneous dissociation temperatures of color-singlet quarkonia and the `quark drip lines' which separate the region of bound $Q\bar Q$ states from the unbound region. The dissociation temperatures of $J/ψ$ and $χ_b$ in quenched QCD are found to be 1.62$T_c$ and $1.18T_c$ respectively, in good agreement with spectral function analyses. The dissociation temperature of $J/ψ$ in full QCD with 2 flavors is found to be 1.42$T_c$. For possible bound quarkonium states with light quarks, the characteristics of the quark drip lines severely limit the stable region close to the phase transition temperature. Bound color-singlet quarkonia with light quarks may exist very near the phase transition temperature if their effective quark mass is of the order of 300-400 MeV and higher.

description: Gauge effects on the fluctuation properties of the normal-to-superconducting phase transition in bulk and thin film superconductors are reviewed. Similar problems in the description of other natural systems (liquid crystals, quantum field theory, early universe) are also discussed. The relatively strong gauge effects on the fluctuations of the ordering field at low spatial dimensionality $D$ and, in particular, in thin (quasi-2D) films are considered in details. A special attention is paid to the fluctuations of the gauge field. It is shown that the mechanism, in which these gauge fluctuations affect the phase transition order and other phase transition properties varies with the variation of spatial dimensionality $D$. The problem for the experimental confirmation of theoretical predictions about the order of phase transitions in gauge systems is discussed. Related topics: gauge effects on the critical behavior of unconventional superconductors, disorder, quantum fluctuations in a close vicinity of ultra-low phase transition temperatures, are also briefly discussed.

description: We simplify the one-loop functional matching formalism to develop a streamlined prescription. The functional approach is conceptually appealing: all calculations are performed within the UV theory at the matching scale, and no prior determination of an Effective Field Theory (EFT) operator basis is required. Our prescription accommodates any relativistic UV theory that contains generic interactions (including derivative couplings) among scalar, fermion, and vector fields. As an example application, we match the singlet scalar extended Standard Model (SM) onto SMEFT.

description: Classical molecular dynamics (MD) is a well established and powerful tool in various fields of science, e.g. chemistry, plasma physics, cluster physics and condensed matter physics. Objects of investigation are few-body systems and many-body systems as well. The broadness and level of sophistication of this technique is documented in many monographs and reviews, see for example \cite{Allan,Frenkel,mdhere}. Here we discuss the extension of MD to quantum systems (QMD). There have been many attempts in this direction which differ from one another, depending on the type of system under consideration. One direction of QMD has been developed for condensed matter systems and will not discussed here, e.g. \cite{fermid}. In this chapter we are dealing with unbound electrons as they occur in gases, fluids or plasmas. Here, one strategy is to replace classical point particles by wave packets, e.g. \cite{fermid,KTR94,zwicknagel06} which is quite successful. At the same time, this method struggles with problems related to the dispersion of such a packet and difficulties to properly describe strong electron-ion interaction and bound state formation. We, therefore, avoid such restrictions and consider a completely general alternative approach. We start discussion of quantum dynamics from a general consideration of quantum distribution functions.

description: We show that quantum pumping does not always require a quantum description or a quantum phase. Quantum pumping is shown to encompass different types of processes, some of which intrinsically rely on phase while others do not. We also show that many pumping processes have a hidden antisymmetric component that contributes significantly to the instantaneous current at the terminals without causing net charge transfer in a period. We have also computed the exact pumped current for some cases over a full range of time variation from adiabatic to non-adiabatic.

Multilateral approaches to the theory of international comparisons
Creators: name: Armstrong, Keir G.
Publisher: name: University of British Columbia
Year: 2009

description: The present thesis provides a definite answer to the question of how comparisons of certain aggregate quantities and price levels should be made across two or more geographic regions. It does so from the viewpoint of both economic theory and the “test” (or “axiomatic”) approach to index-number theory. Chapter 1 gives an overview of the problem of multilateral interspatial comparisons and introduces the rest of the thesis. Chapter 2 focuses on a particular domain of comparison involving consumer goods and services, countries and households in developing a theory of international comparisons in terms of the the (Kontis-type) cost-of-living index. To this end, two new classes of purchasing power parity measures are set out and the relationship between them is explored. The first is the many-household analogue of the (single-household) cost-of-living index and, as such, is rooted in the theory of group cost-of-living indexes. The second Consists of sets of (nominal) expenditure-share deflators, each corresponding to a system of (real) consumption shares for a group of countries. Using this framework, a rigorous exact index- number interpretation for Diewert’s “own-share” system of multilateral quantity indexes is provided. Chapter 3 develops a novel multilateral test approach to the problem at hand by generalizing Eichhorn and Voeller’s bilateral counterpart in a sensible manner. The equivalence of this approach to an extended version of Diewert’s multilateral test approach is exploited in an assessment of the relative merits of several alternative multilateral comparison formulae motivated outside the test-approach framework. Chapter 4 undertakes an empirical comparison of the formulae examined on theoretical grounds in Chapter 3 using an appropriate cross-sectional data set constructed by the Eurostat—OECD Purchasing Power Parity Programme. The principal aim of this comparison is to ascertain the magnitude of the effect of choosing one formula over another. In aid of this, a new indicator is proposed which facilitates the measurement of the difference between two sets of purchasing power parities, each computed using a different multilateral index-number formula.

description: Η παρούσα εργασία ασχολείται με το μυθολογικό έπος De Raptu Proserpinae του λατίνου ποιητή Κλαυδιανού του 4ου αιώνα. Η εργασία αποτελείται από τέσσερα βασικά μέρη: Το Μέρος Ι είναι μια γενικότερη εισαγωγή στη βιογραφία και τη συγγραφική παραγωγή του ίδιου του Κλαυδιανού, ενώ τα Μέρη ΙΙ, ΙΙΙ και IV αφορούν το ίδιο το έργο De Raptu Proserpinae. Συγκεκριμένα το Μέρος ΙΙ αφορά το ίδιο το κείμενο του De Raptu Proserpinae: εδώ θίγεται το πρόβλημα της χρονολόγησης, των συνθηκών σύνθεσης και της παράδοσης του έργου. Το Μέρος ΙΙΙ, που είναι και το βασικότερο, ασχολείται με τις διάφορες πτυχές του De Raptu Proserpinae, όπως τη δομή και το περιεχόμενό του, τις πηγές από τις οποίες έλαβε ο Κλαυδιανός τα δάνειά του για το μύθο της Περσεφόνης, τις ομοιότητες και τις διαφορές που παρουσιάζει το έργο σε σχέση με άλλα έργα που πραγματεύονται τον ίδιο μύθο. Επίσης περιλαμβάνει μια ενότητα που αφορά τη λογοτεχνική τεχνική που ακολουθεί ο Κλαυδιανός στο έργο του και τέλος μια ενότητα που εξετάζει το έργο σε αλληγορικό και συμβολικό επίπεδο. Το Μέρος IV εξετάζει την ιδεολογία του ποιητή, όπως αντικατοπτρίζεται μέσα από το έργο του, δηλαδή πιθανές πολιτικές και προπαγανδιστικές εκφάνσεις και υπαινιγμούς, καθώς επίσης και χριστιανικές και παγανιστικές ιδέες. Η εργασία κλείνει με μια σύντομη αναφορά στις γενικότερες επιδράσεις του Κλαυδιανού και του έργου του σε μεταγενεστέρους.
description: The present paper deals with the mythological epos of Claudius, De Raptu Proserpinae. It consists of four basic parts of which Part I forms a general introduction to the biography and the auctorial production of the poet himself. Parts II, III and IV on the other hand, refer to the epic itself. In particular, Part II deals with the text of De Raptu Proserpinae itself, where the problem of its date and circumstances of composition is addressed, as well as its text-tradition. Part III, which is the most basic one, examines several aspects of the epic, such as its overall structure and content, the sources to which Claudian owes his borrowings for the myth of Persephone, the similarities and differences of Claudian’s version in relation to other works that treat the same mythological theme. It also includes a section regarding the literary qualities and technics that Claudian applies in his work and last but not least a section that goes further to an allegoric and symbolic level of the epic. Part IV touches on the ideology of the poet as reflected on his work, that is, presumptive political and propagandistic allusions and notions in the De Raptu Proserpinae as well as christian or paganistic ideas. The paper concludes with a brief reference to the overall influences of Claudian and his work to his posteriors.

description: Chromatin loop extrusion is a popular model for the formation of CTCF loops and topological domains. Recent HiC data have revealed a strong bias in favour of a particular arrangement of the CTCF binding motifs that stabilize loops, and extrusion is the only model to date which can explain this. However, the model requires a motor to generate the loops, and although cohesin is a strong candidate for the extruding factor, a suitable motor protein (or a motor activity in cohesin itself) has yet to be found. Here we explore a new hypothesis: that there is no motor, and thermal motion within the nucleus drives extrusion. Using theoretical modelling and computer simulations we ask whether such diffusive extrusion could feasibly generate loops. Our simulations uncover an interesting ratchet effect (where an osmotic pressure promotes loop growth), and suggest, by comparison to recent in vitro and in vivo measurements, that diffusive extrusion can in principle generate loops of the size observed in the data.

Slow Star Formation in Dense Gas: Evidence and Implications

description: It has been known for more than 30 years that star formation in giant molecular clouds (GMCs) is slow, in the sense that only ~1% of the gas forms stars every free-fall time. This result is entirely independent of any particular model of molecular cloud lifetime or evolution. Here we survey observational data on higher density objects in the interstellar medium, including infrared dark clouds and dense molecular clumps, to determine if these objects form stars slowly like GMCs, or rapidly, converting a significant fraction of their mass into stars in one free-fall time. We find no evidence for a transition from slow to rapid star formation in structures covering three orders of magnitude in density. This has important implications for models of star formation, since competing models make differing predictions for the characteristic density at which star formation should transition from slow to rapid. The data are inconsistent with models that predict that star clusters form rapidly and in free-fall collapse. Magnetic- and turbulence-regulated star formation models can reproduce the observations qualitatively, and the turbulence-regulated star formation model of Krumholz & McKee quantitatively reproduces the infrared-HCN luminosity correlation recently reported by Gao & Solomon. Slow star formation also implies that the process of star cluster formation cannot be one of global collapse, but must instead proceed over many free-fall times. This suggests that turbulence in star-forming clumps must be driven, and that the competitive accretion mechanism does not operate in typical cluster-forming molecular clumps.

description: We construct a model of set theory in which there exists a Suslin tree and satisfies that any two normal Aronszajn trees, neither of which contains a Suslin subtree, are club isomorphic. We also show that if $S$ is a free normal Suslin tree, then for any positive integer $n$ there is a c.c.c. forcing extension in which $S$ is $n$-free but all of its derived trees of dimension greater than $n$ are special.

description: For a flux qubit described by a two-level system of equations we propose a special time dependent external control field. We show that for a qubit placed in this field there exists a critical value of tunnel frequency. When the tunnel frequency is close to its critical value, the probability value of a definite direction of the current circulating in a Josephson-junction circuit may be kept above 1/2 during a desirable time interval. We also show that such a behavior is not much affected by a sufficiently small dissipation.

On proving consistency of equational theories in Bounded Arithmetic

description: We consider pure equational theories that allow substitution but disallow induction, which we denote as PETS, based on recursive definition of their function symbols. We show that the Bounded Arithmetic theory $S^1_2$ proves the consistency of PETS. Our approach employs models for PETS based on approximate values resembling notions from domain theory in Bounded Arithmetic, which may be of independent interest.

description: The rate of dark matter-electron scattering depends on the underlying velocity distribution of the dark matter halo. Importantly, dark matter-electron scattering is particularly sensitive to the high-velocity tail, which differs significantly amongst the various dark matter halo models. In this work, we summarize the leading halo models and discuss the various parameters which enter them. We recommend updated values for these parameters based on recent studies and measurements. Furthermore, we quantify the dependence of the dark matter-electron scattering rate on the choice of halo model and parameters, and demonstrate how these choices propagate to the predicted cross-section limits. The rate is most sensitive to changes in the circular velocity v0; in silicon targets, we find that the changes in the rate predictions can range from O(0.01%) to O(100%) for contact interactions and O(10%) to O(100%) for long-range interactions.

description: Large-scale {\em ab initio} QED calculations are performed for the $2p_{3/2}$--$2p_{1/2}$ fine-structure interval of Li-like ions with nuclear charges $Z = 5\,$--$\,92$. Improved theoretical predictions are obtained by combining together two complementary theoretical methods, namely, the approach that accounts for all orders in the binding nuclear strength and the nonrelativistic QED approach that accounts for all orders in the nonrelativistic electron-electron interaction. The resulting unified approach provides theoretical predictions which are more accurate than the available experimental results across the interval of the nuclear charges considered.

description: We report results of Canberra-ATCA Doppler-only continuous wave (CW) radar observations of near-Earth asteroid (163899) 2003 SD220 at a receiving frequency of 7159 MHz (4.19 cm) on 2018 December 20, 21, and 22 during its close approach within 0.019 au (7.4 lunar distances). Echo power spectra provide evidence that the shape is significantly elongated, asymmetric, and has at least one relatively large concavity. An average spectrum per track yields an OC (opposite sense of circular polarisation) radar cross section of 0.39, 0.27, and 0.25 km$^{2}$, respectively, with an uncertainty of 35 \%. Variations by roughly a factor of two in the limb-to-limb bandwidth over the three days indicate rotation of an elongated object. We obtain a circular polarization ratio of 0.21 $\pm$ 0.07 that is consistent with, but somewhat lower than, the average among other S-class near-Earth asteroids observed by radar.

description: Anti-ferromagnetic materials have the possibility to offer ultra fast, high data density spintronic devices. A significant challenge is the reliable detection of the state of the antiferromagnet, which can be achieved using exchange bias. Here we develop an atomistic spin model of the athermal training effect, a well known phenomenon in exchange biased systems where the bias is significantly reduced after the first hysteresis cycle. We find that the setting process in granular thin films relies on the presence of interfacial mixing between the ferromagnetic and antiferromagnetic layers. We systematically investigate the effect of the intermixing and find that the exchange bias, switching field and coercivity all increase with increased intermixing. The interfacial spin state is highly frustrated leading to a systematic decrease in interfacial ordering of the ferromagnet. This metastable spin structure of initially irreversible spins leads to a large effective exchange coupling and thus large increase in the switching field. After the first hysteresis cycle these metastable spins drop into a reversible ground state that is repeatable for all subsequent hysteresis cycles, demonstrating that the effect is truly athermal. Our simulations provide new insights into the role of interface mixing and the importance of metastable spin structures in exchange biased systems which could help with the design an optimisation of antiferromagnetic spintronic devices.

Research on Hidden Variable Theories: a review of recent progresses

Year: 2007
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Quantum Mechanics (QM) is one of the pillars of modern physics: an impressive amount of experiments have confirmed this theory and many technological applications are based on it. Nevertheless, at one century since its development, various aspects concerning its very foundations still remain to be clarified. Among them, the transition from a microscopic probabilistic world into a macroscopic deterministic one and quantum non-locality. A possible way out from these problems would be if QM represents a statistical approximation of an unknown deterministic theory. This review is addressed to present the most recent progresses on the studies related to Hidden Variable Theories (HVT), both from an experimental and a theoretical point of view, giving a larger emphasis to results with a direct experimental application. More in details, the first part of the review is a historical introduction to this problem. The Einstein-Podolsky-Rosen argument and the first discussions about HVT are introduced, describing the fundamental Bell's proposal for a general experimental test of every Local HVT and the first attempts to realise it. The second part of the review is devoted to elucidate the recent progresses toward a conclusive Bell inequalities experiment obtained with entangled photons and other physical systems. Finally, the last sections are targeted to shortly discuss Non-Local HVT.
