description: We introduce a class of new algebras, the shifted quiver Yangians, as the BPS algebras for type IIA string theory on general toric Calabi-Yau three-folds. We construct representations of the shifted quiver Yangian from general subcrystals of the canonical crystal. We derive our results via equivariant localization for supersymmetric quiver quantum mechanics for various framed quivers, where the framings are determined by the shape of the subcrystals. Our results unify many known BPS state counting problems, including open BPS counting, non-compact D4-branes, and wall crossing phenomena, simply as different representations of the shifted quiver Yangians. Furthermore, most of our representations seem to be new, and this suggests the existence of a zoo of BPS state counting problems yet to be studied in detail.

description: Let $X\to¶^n$ be an irreducible holomorphic symplectic manifold of dimension $2n$ fibred over $¶^n$. Matsushita proved that the generic fibre is a holomorphic Lagrangian abelian variety. In this article we study the discriminant locus $Δ\subset¶^n$ parametrizing singular fibres. Our main result is a formula for the degree of $Δ$, leading to bounds on the degree when $X$ is a four-fold.

A conceptual look at empathy: implications for moral education
Creators: name: Jeffers, Elizabeth W.
Publisher: name: University of British Columbia
Year: 2009

description: Drawing on current educational, psychological and philosophical literature, this thesis addresses the diversity of the meaning of the term empathy as used in the literature and the consequences that emphasizing some meamngs over others may have for moral education. Making sense of the conceptual confusion is of utmost importance to educators in terms of what they can legitimately pursue in attempting to cultivate and increase empathic understanding in students. The meanings of the term serve as a basis for an analysis of the concept and the development of a new conception of empathy-one specifically developed for moral education. If the concept of empathy is to go beyond our ordinary language use to be of significant use in an education aimed at promoting respect for others, it must be specified that having empathic receptions involves taking the humanity of another seriously. Empathy, as this notion is developed and justified throughout the thesis, involves seeing others as fully human and having a genuine concern for the welfare of others. This conception which includes these compassionate dispositions is further developed and justified to provide a basis for future empirical research on the acquisition of empathy among children and for the production of appropriate ways to develop empathic understanding in students.

description: In this diploma thesis we will analyze and comment on Articles 62 to 73 of the Regulation referring to the European Certificate of Succession, comparing them with the provisions concerning the Certificate of Inheritance applicable in Greek law. From the comparative study, we will determine what are the similarities and differences between the two institutions of the Certificate. Next, we will discuss the new elements that are introduced by the European Succession Certificate into the Greek law, what extent it differs from the national procedural rules, if and what contributes to the Greek procedural order. Finally, the findings and conclusions from the future use of the European Certificate of Succession will be recorded. Until the time of writing, European inheritances have not been issued by the Greek courts actually the local Courts of Justice of the country. From search and research through the legal bases, no European Certificate of Succession was found issued up to the time of writing this thesis, as the implementation of Regulation 650/2012 was only recently launched on 17-8-2015. For the same reason the bibliography used is equally limited and comes mainly from analyzes, studies and books that were co-authored for the national succession certificate.

description: We consider a system realized with one spinless quantum particle and an array of $N$ spins 1/2 in dimension one and three. We characterize all the Hamiltonians obtained as point perturbations of an assigned free dynamics in terms of some ``generalized boundary conditions''. For every boundary condition we give the explicit formula for the resolvent of the corresponding Hamiltonian. We discuss the problem of locality and give two examples of spin dependent point potentials that could be of interest as multi-component solvable models.

description: The quantum world distinguishes itself from the classical world by being governed by probability amplitudes rather than probabilities. On a single-particle level, quantum phases can be manipulated leading to observable interference patterns that can be used as a probe e.g. in matter wave microscopy. But the quantum world bears even more fascinating effects when it comes to the interplay between more than one particle. Correlations between quantum particles such as entanglement can be exploited to speed up computational algorithms or enable secure cryptography. Here, we propose and numerically explore a thought experiment to address the question whether quantum correlations between particles can be used in matter wave microscopy. Specifically, we address the following questions: How can information be transferred between two mutually spin-correlated free-electron wavepackets? Can Coulomb and exchange correlations be linked to the decoherence mechanism of matter waves? Using a time-dependent Hartree-Fock algorithm, we will show that the exchange term has a substantial role in transferring the information between two mutually spin-correlated electrons, whereas the Hartree potential (or mean-field Coulomb potential) dominates the dephasing on a single-particle level. Our findings might facilitate fermionic matter-wave interferometry experiments in which it is possible to retrieve information about non-classical correlations and the mechanism of decoherence in open versus closed quantum systems.

Σκοπός της εργασίας είναι να υπολογιστούν τα τυρβώδη χαρακτηριστικά της ροής για δύο διαφορετικές διατάξεις ανοιγμάτων των αγροτικών κατασκευών. Για τη μελέτη της ροής του αέρα γύρω από τα εμπόδια, χρησιμοποιήθηκε το μοντέλο της άμεσης αριθμητικής προσομοίωσης , το οποίο επιλύθηκε με την μέθοδο των πεπερασμένων στοιχείων. Η ροή είναι ασταθής, ασυμπίεστη και δισδιάστατη. Ο αριθμός Reynolds που χρησιμοποιήθηκε είναι 2800 και αντιστοιχεί σε ταχύτητα αέρα u=7 m/s. Από την στατιστική επεξεργασία των στιγμιαίων αριθμητικών προβλέψεων των ταχυτήτων προέκυψαν τα χαρακτηριστικά μεγέθη της τυρβώδους ροής όπως: η τυρβώδης ένταση, οι τάσεις Reynolds και η τυρβώδης κινητική ενέργεια ( Τ.Κ.Ε). Για την επαλήθευση του αριθμητικού πειράματος έγινε σύγκριση των αριθμητικών προβλέψεων της τυρβώδους κινητικής ενέργειας με αντίστοιχες εργαστηριακές μετρήσεις άλλων ερευνητών.
description: In the present paper, was studied the airflow inside and outside rural constructions, with side openings, which were located inside the wind tunnel. The purpose of this paper was to calculate the turbulent air flow characteristics of two rural constructions with different ventilation openings. For the study of the air flow around obstacles, it was used a direct numerical simulation model (DNS), which was solved by the finite element method. The flow is unstable, two-dimensional and incompressible. The Reynolds number used is 2800, corresponding to a wind speed u = 7 m / s. From the statistical analysis of the instantaneous numerical estimation of air speeds, we took the following results of turbulent air flow characteristics: turbulent intensity, the Reynolds stresses and turbulent kinetic energy. In order to verify the numerical experiment, we have compared the numerical predictions of turbulent kinetic energy with corresponding laboratory measurements of other researchers.

description: The Bardeen-Cooper-Schrieffer (BCS) mean-field theory of the pairing interaction breaks down for nuclei and ultra-small metallic grains (nanoparticles). Finite-temperature pairing correlations in such finite-size systems can be calculated beyond the BCS theory in an auxiliary-field Monte Carlo approach. We identify thermal signatures of pairing correlations in both nuclei and nanoparticles that depend on the particle-number parity.

The Abrikosov Vortex in Curved Space

description: We study the self-gravitating Abrikosov vortex in curved space with and without a (negative) cosmological constant, considering both singular and non-singular solutions with an eye to hairy black holes. In the asymptotically flat case, we find that non-singular vortices round off the singularity of the point particle's metric in 3 dimensions, whereas singular solutions consist of vortices holding a conical singularity at their core. There are no black hole vortex solutions. In the asymptotically AdS case, in addition to these solutions there exist singular solutions containing a BTZ black hole, but they are always hairless. So we find that in contrast with 4-dimensional 't Hooft-Polyakov monopoles, which can be regarded as their higher-dimensional analogues, Abrikosov vortices cannot hold a black hole at their core. We also describe the implications of these results in the context of AdS/CFT and propose an interpretation for their CFT dual along the lines of the holographic superconductor.

description: The photoproduction reaction of $γp \to K^+Λ(1405)$ is investigated based on an effective Lagrangian approach at the tree-level approximation with the purpose of understanding the reaction mechanism and extracting the resonance contents and the associated resonance parameters in this reaction. Apart from the $t$-channel $K$ and $K^\ast$ exchanges, $s$-channel nucleon ($N$) exchange, $u$-channel $Σ$, $Λ$, and $Λ(1405)$ exchanges, and generalized contact term, the exchanges of a minimum number of $N$ resonances in the $s$ channel are taken into account in constructing the reaction amplitudes to describe the experimental data. It is found that by introducing the $N(2000){5/2}^+$ resonance exchange in the $s$ channel, one can reproduce the most recent differential cross-section data from the CLAS Collaboration quite well. Further analysis shows that the cross sections of $γp \to K^+Λ(1405)$ at high energies are dominated by the $t$-channel $K$ exchange, while the contributions from the $s$-channel $N$ and $N(2000){5/2}^+$ exchanges are rather significant to the cross sections in the near-threshold energy region. Predictions for the beam and target asymmetries for $γp \to K^+Λ(1405)$ are given.

Χρησιμοποιήθηκαν 3 φωτοπολυμεριζόμενες ακρυλικές ρητίνες και 1 αυτοπολυμεριζόμενη ως υλικό μάρτυρας. ¨Έγινε λήψη φασμάτων από την άνω και κάτω επιφάνεια πολύ λεπτών δοκιμίων, αφού ακτινοβολήθηκαν σε συσκευή φωτοπολυμερισμού από 0 μέχρι 5 min. Επίσης μετρήθηκε η μικροσκληρότητα στην άνω και κάτω επιφάνεια δοκιμίων πάχους 5 mm, που είχαν ακτινοβοληθεί επί 3, 5, 10 min, αμέσως μετά τον πολυμερισμό και μετά την παρέλευση 24 ωρών. Διαπιστώθηκε ότι η άνω επιφάνεια όλων των υλικών πολυμερίζεται στα 3 min, η κάτω επιφάνεια καθυστερεί σε σχέση με την άνω, ενώ η παραμονή για 24 ώρες μπορεί να βελτιώσει τη σκληρότητα. Όλες οι αντίστοιχες επιφάνειες των φωτοπολυμεριζόμενων υλικών πολυμερίζονται με τον ίδιο ρυθμό τόσο μεταξύ τους όσο και σε σχέση με το αυτοπολυμεριζόμενο, ενώ, μετά την παρέλευση 24 ωρών, τα φωτοπολυμεριζόμενα υλικά είναι περισσότερο σκληρά από το αυτοπολυμεριζόμενο.
description: The effect of irradiation time and measurement time ( immediate after irradiation or after 24 hours ) on the depth of cure of selected visible light cured ( VLC ) tray resins was studied through FTIR-ATR infrared spectroscopy and surface microhardness evaluation. Three VLC tray resins were tested. One autopolymerizing acrylic resin was included as the control material. In the first part of the study were fabricated very thin circular film specimens for each material and for 8 irradiation times from 0 to 5 min. The specimens were irradiated in a light curing device and then placed on the spectrometer to obtain absorption infrared spectra of their upper and bottom surfaces. In the second part of the study were fabricated rectangular specimens of 5 mm thickness for each material and for 3 irradiation times (3, 5, 10 min) and then subjected to Knoop microhardness measurement of the upper and lower surfaces, both immediately after irradiation and 24 hours after it. It was concluded that the top surfaces of all tested materials polymerize after a 3min irradiation but the bottom surfaces’ polymerization is delayed relative to the top surfaces. When the material is thick, it cannot be cured in less than 5 min irradiation time, but in case of insufficient irradiation, a storage time of 24 hours can improve depth of cure. All the respective top and bottom surfaces of the 3 visible light cured materials are polymerized at the same rate relative to the autopolymerizing. After a storage time of 24 hours though, the visible light cured materials are more hard than the autopolymerizing.

description: We study a precise and computationally tractable notion of operator complexity in holographic quantum theories, including the ensemble dual of Jackiw-Teitelboim gravity and two-dimensional holographic conformal field theories. This is a refined, "microcanonical" version of K-complexity that applies to theories with infinite or continuous spectra (including quantum field theories), and in the holographic theories we study exhibits exponential growth for a scrambling time, followed by linear growth until saturation at a time exponential in the entropy $\unicode{x2014}$a behavior that is characteristic of chaos. We show that the linear growth regime implies a universal random matrix description of the operator dynamics after scrambling. Our main tool for establishing this connection is a "complexity renormalization group" framework we develop that allows us to study the effective operator dynamics for different timescales by "integrating out" large K-complexities. In the dual gravity setting, we comment on the empirical match between our version of K-complexity and the maximal volume proposal, and speculate on a connection between the universal random matrix theory dynamics of operator growth after scrambling and the spatial translation symmetry of smooth black hole interiors.

description: A central question in the underdoped cuprates pertains to the nature of the pseudogap ground state. A conventional metallic ground state of the pseudogap region has been argued to host quantum oscillations upon destruction of the superconducting order parameter by modest magnetic fields. Here we use low applied measurement currents and millikelvin temperatures on ultra-pure single crystals of underdoped YBa$_2$Cu$_3$O$_{6+x}$ to unearth an unconventional quantum vortex matter ground state characterized by vanishing electrical resistivity, magnetic hysteresis, and non-ohmic electrical transport characteristics beyond the highest laboratory accessible static fields. A new model of the pseudogap ground state is now required to explain quantum oscillations that are hosted by the bulk quantum vortex matter state without experiencing sizeable additional damping in the presence of a large maximum superconducting gap; possibilities include a pair density wave.

The aim of this investigative effort is to create a glossary of anatomical terms of human body from the Greek to the Spanish language. In the beginning, it is clarified what terminology is. There is also reference to the concept, which is one of the basic structural terminological components, as well as it is explained the structure of a glossary. Moreover the term is defined. This is followed by the redaction of the glossary as well as a qualitative approach of terms, in both Greek and Spanish. The structures of the terms are explicated morphologicaly at a synchronic level and then their historical origins are investigated at a diachronic level

description: We study the overdamped version of two coupled anharmonic oscillators under the influence of both low- and high-frequency forces respectively and a Gaussian noise term added to one of the two state variables of the system. The dynamics of the system is first studied in the presence of both forces separately without noise. In the presence of only one of the forces, no resonance behaviour is observed, however, hysteresis happens there. Then the influence of the high-frequency force in the presence of a low-frequency, i.e. biharmonic forcing, is studied. Vibrational resonance is found to occur when the amplitude of the high-frequency force is varied. The resonance curve resembles a stochastic resonance-like curve. It is maximum at the value of $g$ at which the orbit lies in one well during one half of the drive cycle of the low-frequency force and in the other for the remaining half cycle. Vibrational resonance is characterized using the response amplitude and mean residence time. We show the occurrence of stochastic resonance behaviour in the overdamped system by replacing the high-frequency force by Gaussian noise. Similarities and differences between both types of resonance are presented.

description: The Navier-Stokes transport coefficients for binary mixtures of smooth inelastic hard disks or spheres under gravity are determined from the Boltzmann kinetic theory by application of the Chapman-Enskog method for states near the local homogeneous cooling state. It is shown that the Navier-Stokes transport coefficients are not affected by the presence of gravity. As in the elastic case, the transport coefficients of the mixture verify a set of coupled linear integral equations that are approximately solved by using the leading terms in a Sonine polynomial expansion. The results reported here extend previous calculations [V. Garzó and J. W. Dufty, Phys. Fluids {\bf 14}, 1476 (2002)] to an arbitrary number of dimensions. To check the accuracy of the Chapman-Enskog results, the inelastic Boltzmann equation is also numerically solved by means of the direct simulation Monte Carlo method to evaluate the diffusion and shear viscosity coefficients for hard disks. The comparison shows a good agreement over a wide range of values of the coefficients of restitution and the parameters of the mixture (masses and sizes).

description: The standard diffusive spreading, characterized by a Gaussian distribution with mean square displacement that grows linearly with time, can break down, for instance, under the presence of correlations and heterogeneity. In this work, we consider the spread of a population of fractional (long-time correlated) Brownian walkers, with time-dependent and heterogeneous diffusivity. We aim to obtain the possible scenarios related to these individual-level features from the observation of the temporal evolution of the population spatial distribution. We develop and discuss the possibility and limitations of this connection for the broad class of self-similar diffusion processes. Our results are presented in terms of a general framework, which is then used to address well-known processes, such as Laplace diffusion, nonlinear diffusion, and their extensions.

description: The increased digitalisation and monitoring of the energy system opens up numerous opportunities to decarbonise the energy system. Applications on low voltage, local networks, such as community energy markets and smart storage will facilitate decarbonisation, but they will require advanced control and management. Reliable forecasting will be a necessary component of many of these systems to anticipate key features and uncertainties. Despite this urgent need, there has not yet been an extensive investigation into the current state-of-the-art of low voltage level forecasts, other than at the smart meter level. This paper aims to provide a comprehensive overview of the landscape, current approaches, core applications, challenges and recommendations. Another aim of this paper is to facilitate the continued improvement and advancement in this area. To this end, the paper also surveys some of the most relevant and promising trends. It establishes an open, community-driven list of the known low voltage level open datasets to encourage further research and development.

description: Abstract Background: Mental illnesses are more common among the prison population than the general public. However, little attention is given to mental health service in low and middle income countries in general. The problem is more so for prisoners where the overall health care is poor. Therefore, the aim of this study was to assess the prevalence of anxiety and the associated factors among prisoners of North West Amhara, Ethiopia. Methods: Institutional based cross-sectional study was employed from February to March 2015 by taking a sample of 700 prisoners. Simple random sampling method was employed to select three prisons out of 10 prisons found in the North West Amhara region. Generalized Anxiety Disorder 7-item (GAD-7) scale was used to assess prisoners’ anxiety status. The receiver- operator characteristic (ROC) curve was used to determine the cutoff point with high sensitivity and specificity. Structured and pretested interviewer administered questionnaire was used for data collection. Data were checked, coded and entered into Epi Info version 7 and analyzed using R version 3.2.0. Bivariable and multivariable logistic regression analyses were carried out to identify factors associated with anxiety. Odds ratio with its 95 % confidence interval was used as a measure of association. Akaike’s Information’s Criterion (AIC) was used to check model fitness. Results: A total of 649 prisoners were included in the analysis making the response rate 92.5 %. The prevalence of Anxiety was found to be 36.1 % (95 % CI: 32.7, 39.9). The odds of Anxiety was 2.49(95 % CI: 1.38, 4.55) times higher among prisoners who used to be unhappy in their life before imprisonment. Moreover, smokers were 2.6 (AOR=2.6, 95 % CI: 1.08, 6.6) times more likely to have anxiety compared with non smokers. However, the odds of the odds of anxiety was 89% lower among Debre-Tabor prisoners (AOR=0.11, 95 % CI: 0.06, 0.20) and 57 % lower among Gondar prisoners (AOR=0.43, 95 % CI: 0.28, 0.67). Conclusion: The prevalence of anxiety is found to be very high among prisoners in North West Ethiopia. Anxiety was associated with current smoking and having had a dissatisfying life. Screening prisoners for common mental disorders and integrated health care is necessary. Keywords: Anxiety, Cross-sectional study, Prisoner

description: Pastoralists are among the marginalized groups of society who live in a marginalized environment and whose livelihood is exposed to the vagaries of climate and harsh environmental conditions. This study explores into impediments of pastoral children’s participation into schooling and education with particular emphasis on the primary school of selected Woreda, Afar Zone. To achieve this purpose, a qualitative research method was employed. Participants of the study were selected by employing purposive sampling mainly on the basis of their roles related to schooling. Seven members of parent teacher associations, 20 teachers, 4 school principals, 14 education experts and officials, a total of45 respondents took part in the study. Data were collected through the use of different instruments: Strutted interview, focus group discussion, and document review and observation checklist. The data obtained through these data collection instruments were analysed thematically. The steps involved were organizing and preparing data for analysis, reading through all data, coding, generating a description of the settings and people and identifying categories or themes for analysis, representing descriptions and themes in the qualitative narrative and interpretation. The study identified several cultural and economic barriers such as early marriage, lack of interest for modern education, parental level of education, mobility, child labor, poverty and finance. The results also showed that existence of both supply and demand side constraints. Problem of funding, inability to attract and retain qualified teaching staff, poorly equipped schools and community perception of modern education as a threat to pastoralist way of life were the major supply related shortcomings. The demand side limitations were identified as dispersed settlement patterns, demand for child labour, bride-price and peer pressure. Mandatory seasonal mobility, frequent conflicts and conflict induced displacement were cited as the most pronounced disenabling features. Drought and harsh weather were the driving forces of mobility. Competition over water sources and pastureland coupled with border dispute and cattle raid were identified as the long standing causes of armed conflict which in turn result in school activity disruption. Thus, based on the findings, recommendation is made to planners and policymakers so as to alleviate the observed shortcomings. Improving quality of school facilities, sensitization campaign on the benefits of education, blended mode of delivery, peace dialogue to arrest recurring conflicts, self-proof of schools about their worthiness to the local community and rethinking of teacher incentive mechanisms are some of the important propositions made in view to avert the long standing legacy of educational under representation of the Afar pastoralist communities in Ethiopia.

description: Σκοπός της παρούσας διπλωματικής εργασίας είναι η ανάλυση του μεγάλου μας ποιητή Οδυσσέα Ελύτη, μέσω των δύο σημαντικών έργων του: Εν Λευκώ και Ανοιχτά Χαρτιά. Αναλύσαμε την αγάπη του για την Ελλάδα και το Αιγαίο, παρακολουθήσαμε την διαλογή του με την φύση, τον ακολουθήσαμε στην προσπάθειά του για την οικουμενικότητα του ανθρωπισμού του, παρατηρήσαμε την αισιοδοξία που έφερε στην ελληνική λογοτεχνία, συγκινηθήκαμε με το μεγαλείο του ελληνισμού που διαπνέει όλο το έργο του. Ο λόγος του γονιμοποιεί και δίνει σάρκα και οστά και πνεύμα στο όνειρο της ελευθερίας και της ανθρώπινης αξιοπρέπειας. Η ελληνική γλώσσα, δεν είναι απλά ένα μέσο επικοινωνίας αλλά κουβαλάει την ψυχή και την ιστορία του λαού. Μέσω των έργων του κατανοήσαμε όλη την πνευματική και ποιητική πορεία του ποιητή. Κείμενα για τον Παπαδιαμάντη, τον Άγιο Ρωμανό τον Μελωδό, τον Ανδρέα Εμπειρίκο, τον Ανδρέα Κάλβο, κείμενα για την αναλογία ζωγραφικής και ποίησης, αλλά κι ένα «ημερολόγιο» φτιαγμένο από χρονικά ανακόλουθες προσωπικές μνήμες, αποτελούν το παγιωμένο τρόπο σκέψης και αισθητικό ύφος του ποιητή. Ο Ελύτης και τα έργα του αποτελούν για όποιον συναναστρέφεται με αφοσίωση την ποίηση μια έκτακτη περίπτωση άξια σπουδής
description: The purpose of this diploma thesis is the analysis of our great poet Odysseas Elytis, through his two major works: En Lefco and Anechta Chartia. We analyzed his love for Greece and the Aegean, we followed his screening with nature, followed him in his effort for the universality of his humanity, observed the optimism he brought to Greek literature, we were moved with the greatness of Hellenism that inspires the whole his work. His speech fertilizes and gives flesh and bones and spirit to the dream of freedom and human dignity. Τhe Greek language, is not just a mean of communication but carries the soul and history of the people. Through his works, we understood the poet's whole spiritual and poetic course. Texts for Papadiamantis, Saint Romanos the Melodist, Andreas Ebericos, Andreas Calvos, texts on painting and poetry ratio, but also a "diary" made from time-inconsistent personal memories are the entrenched mindset and aesthetic style of the poet. Elytis and his works are for anyone engaged in dedication poetry an extraordinary case worthy of study

description: The dilepton production at backward rapidities in $pAu$ and $pp$ collisions at RHIC and LHC energies is investigated in the dipole approach. The results are shown through the nuclear modification ratio $R_{pA}$ considering transverse momentum and rapidity spectra. The dilepton modification ratio presents interesting behavior at the backward rapidities when compared with the already known forward ones, since it is related with the large $x$ kinematical region that is being probed. The rapidity dependence of the nuclear modification ratio in the dilepton production is strongly dependent on the Bjorken $x$ behavior of the nuclear structure function ratio $R_{F_{2}}=F_{2}^{A}/F_{2}^{p}$. The $R_{pA}$ transverse momentum dependence at backward rapidities is modified due to the large $x$ nuclear effects: at RHIC energies, for instance, the ratio $R_{pA}$ is reduced as $p_T$ increases, presenting an opposite behavior when compared with the forward one. It implies that the dilepton production at backward rapidities should carry information of the nuclear effects at large Bjorken $x$, as well as that it is useful to investigate the $p_T$ dependence of the observables in this kinematical regime.

description: Quantum theories of gravity predict interesting phenomenological features such as a minimum measurable length and maximum momentum. We use the Generalized Uncertainty Principle (GUP), which is an extension of the standard Heisenberg Uncertainty Principle motivated by Quantum Gravity, to model the above features. In particular, we use a GUP with modelling maximum momentum to establish a correspondence between the GUP-modified dynamics of a massless spin-2 field and quadratic (referred to as Stelle) gravity. In other words, Stelle gravity can be regarded as the classical manifestation of a maximum momentum and the related GUP. We explore the applications of Stelle gravity to cosmology and specifically show that Stelle gravity applied to a homogeneous and isotropic background leads to inflation with an exit. Using the above, we obtain strong bounds on the GUP parameter from CMB observations. Unlike previous works, which fixed only upper bounds for GUP parameters, we obtain both \emph{lower and upper bounds} on the GUP parameter.
