Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Resonant production of scalar bottom, which is allowed in R-parity violating interactions of supersymmetry, has been investigated at the LHeC collider. Although searching for the physics beyond the standard model is a primary task of the LHC, recently, an $\mathit{e^{-}p}$ collider (LHeC) is proposed to complement and resolve the observation of new phenomena at the TeV scale. In this paper, we have studied on the prospects of improving constraints for $\hat{L}\hat{Q}\hat{D}$ couplings $λ_{ijk}'$ through the process $\mathit{e^{-}+p\rightarrow\widetilde{b^{*}}\rightarrowμ^{-}+\bar{q}}$ where $\mathit{q}$ denotes the up type quarks. It is shown that constraints on $λ_{ijk}'$ can be improved up to 10^{-3} for 1\: fb^{-1} integrated luminosity at 95% C.L. with 60 GeV $\mathit{e^{-}}$ beam option of the LHeC.

Για την ηλεκτρική τροφοδότηση της οικίας επιλέγεται αυτόνομο σύστημα με τη χρήση φωτοβολταϊκών, συσσωρευτών και εφεδρικής γεννήτριας. Γίνεται πλήρης διαστασιολόγηση του εξοπλισμού που απαρτίζει το αυτόνομο σύστημα, με βάση την ημερήσια κατανάλωση ενέργειας του χρήστη της οικίας και τη μέγιστη ταυτοχρονισμένη ισχύ των ηλεκτρικών συσκευών της. Εξετάζονται τεχνοοικονομικά διαφορετικά σενάρια αυτονόμησης της οικίας, είτε με τη χρήση μεγαλύτερου συστήματος αποθήκευσης, είτε μεγαλύτερου αντιστροφέα για τη βελτίωση των συνθηκών άνεσης της οικίας λόγω της μεγαλύτερης αυτονομίας και της ταυτοχρονισμένης τροφοδότησης περισσότερων ηλεκτρικών συσκευών.

Για την υπολογισμό της διατομής του καλωδίου παροχής λαμβάνεται υπόψη η ικανότητα φόρτισης του καλωδίου βάσει του Προτύπου ΕΛΟΤ ΗD384 και η επιτρεπόμενη πτώση τάσης.

description: In this diploma thesis, the electrical installation of a house located at distance from the distribution network, is being studied and planned.
A stand-alone system is selected for the electrical supply of the house using photovoltaics, a storage system with batteries and a backup generator. The complete set up of the stand-alone equipment is made on the basis of the household energy consumption of the home and the simultaneous supply of electrical appliances. The daily energy consumption determines the size of the photovoltaic system and the capacity of the batteries, and the simultaneous power of the household devices determines the rated power of the inverter and the generator. Different techno economical scenarios of house autonomy are being studied, using either a bigger storage system or a larger inverter, in order to improve the comfort level of the house due to greater autonomy as well as simultaneous power supply of more electrical appliances.
Finally, the internal and external electrical installation of the house is being studied and planned, according to the HD384 Standard. Detailed drawings are provided, single-line diagrams of the installation and the panels, while the cross-section of an underground supply cable for an additional building that functions as a guest house is calculated. In order to calculate the cross-section of the supply cable, the cable charging capacity is taken into account based on the HD384 Standard and the acceptable voltage drop.

description: Excerpt from the report: The objectives of the study were to determine (1) the level of and trends in sales of dehydrated mashed potatoes and frozen french fries in retail food outlets; (2) trends in use, marketing practices, and problems in the use of dehydrated mashed potatoes and frozen french fries in selected segments of the institutional market; and (3) the net effect of increased use of potatoes in processed form on total consumption of potatoes and on returns to growers. Special emphasis was given to dehydrated and frozen potato products because these offer the greatest potential for expanding the use of potatoes. Within the last several years, marked increases have been observed in the utilization of potatoes by freezers and dehydrators. Nearly 13.4 million hundredweight of potatoes were used in making frozen french fries in 1960, double the quantity used in 1958. Processors of flakes, granules, and other forms of dehydrated potatoes used 10.1 million hundredweight from the 1960 crop or twice the quantity used from the 1958 crop.

description: Although credit cards are more expensive for merchants to accept than cash or debit cards, merchants typically pass through their costs evenly to all customers. Along with consumer card rewards and banking fees, this creates cross-subsidies between payment methods. Because higher-income individuals tend to use credit cards more than those with lower incomes, our results indicate that these cross-subsidies might lead to regressive distributional effects.

description: Même s’il est plus coûteux pour eux d’accepter les paiements par carte de crédit qu’en argent comptant ou par carte de débit, les commerçants répercutent généralement ces coûts de façon égale sur l’ensemble de leurs clients. Ces coûts, ainsi que les frais bancaires et les récompenses que les consommateurs obtiennent pour avoir utilisé leur carte de paiement, créent un interfinancement des différents modes de paiement. Nos résultats indiquent que, puisque les personnes à revenu élevé ont plus tendance à utiliser les cartes de crédit que celles à faible revenu, cet interfinancement pourrait entraîner des effets redistributifs régressifs.

description: We study a model (i.e., the $t_2-V$ model involving {\em next-nearest-neighbor hopping} and nearest-neighbor repulsion) in one-dimension that generically depicts the dominant transport mechanism in cooperative strong electron-phonon interaction systems. Using analytic and numerical approaches, hard-core-bosons are shown to typically undergo a striking discontinuous transition from a superfluid to a supersolid. Topological inequivalence of rings with even and odd number of sites is manifested through observable differences (in structure factor peaks) at the transition. Connections are also identified between the $t_2-V$ model and other topologically interesting models.

description: Many central banks conduct economic field research involving in-depth interviews with external parties. But very little is known about how this information is used and its importance in the formation of monetary policy. We address this gap in the literature through a thematic analysis of open-ended interviews with senior central bank economic and policy staff who work closely with policy decision-makers. We find that these central bankers consider information from field research programs not just useful but also an essential input for monetary policy making. They use this information in conjunction with quantitative tools primarily to inform their near-term forecasts. The information is considered most valuable at potential turning points in the economy when uncertainty about the pace of economic growth is heightened (in the advent of large shocks to the economy) and when timely official data are not available or are viewed as unreliable. Senior staff also place a high value on maintaining a reliable and credible sample of representative economic agents that can be accessed on an ongoing basis and very quickly when required.

description: Beaucoup de banques centrales mènent des recherches sur le terrain au cours desquelles elles effectuent des entretiens approfondis avec des acteurs du tissu économique de leur pays. Cependant, on en sait très peu sur la manière dont les renseignements ainsi recueillis sont utilisés et sur l’importance qu’ils revêtent dans la conduite de la politique monétaire. Pour remédier à cette lacune, nous réalisons une analyse thématique d’entretiens à questions ouvertes menés auprès de cadres supérieurs de banques centrales chargés des questions d’analyse et de politique économiques et qui travaillent de près avec les décideurs de leur institution. Nous constatons que, pour ces cadres, les renseignements obtenus lors des recherches sur le terrain sont non seulement utiles, mais aussi essentiels pour la formulation de la politique monétaire. Les cadres se servent de ces renseignements conjointement avec des outils quantitatifs, principalement pour éclairer leurs prévisions à court terme. Ces renseignements s’avèrent très précieux dans deux cas : quand l’économie pourrait se trouver à un point de retournement compte tenu de l’incertitude élevée entourant le rythme de croissance économique (lorsque l’économie subit des chocs importants); et quand des données officielles à jour ne sont pas disponibles ou qu’elles ne sont pas considérées comme fiables. Les cadres supérieurs accordent aussi une grande importance au maintien d’un échantillon fiable et crédible d’agents économiques représentatifs qu’ils peuvent consulter régulièrement et très rapidement, au besoin.

description: The experimental results that test Bell's inequality have found strong evidence suggesting that there are nonlocal aspects in nature. Evidently, these nonlocal effects, which concern spacelike separated regions, create an enormous tension between general relativity and quantum mechanics. In addition, by avoiding the coincidence limit, semiclassical gravity can also accommodate nonlocal aspects. Motivated by these results, we study if it is possible to construct geometrical theories of gravitation that are nonlocal in the sense of Bell. We propose three constructions of such theories, which could constitute an important step towards our understanding of the interplay between quantum mechanics and gravitation.

Σκοπός αυτής της διπλωματικής εργασίας ήταν η συγκριτική αξιολόγηση της ακρίβειας εναλλακτικών μοντέλων φωτοβολταϊκών στοιχείων. Αρχικά, τα μοντέλα αυτά υλοποιήθηκαν σε περιβάλλον Matlab και μελετήθηκε η συμπεριφορά τους για διάφορες συνθήκες προσπίπτουσας ηλιακής ακτινοβολίας και θερμοκρασίας περιβάλλοντος των φωτοβολταϊκών στοιχείων. Στη συνέχεια, μετρήθηκαν πειραματικά οι χαρακτηριστικές ρεύματος-τάσης δύο εμπορικά διαθέσιμων φωτοβολταϊκών πλαισίων με διαφορετικές τεχνολογίες κατασκευής. Με βάση τα πειραματικά αποτελέσματα που προέκυψαν, πραγματοποιήθηκε συγκριτική αξιολόγηση της ακρίβειας των θεωρητικών μοντέλων των φωτοβολταϊκών στοιχείων.

description: International investment treaties entrench and exacerbate intra-national inequality by: 1) Providing stronger substantive legal rights to a certain class of actors that in turn strengthen the legal force of their economic rights and “expectations”, with potentially negative impacts on the competing rights and interests of other stakeholders; and 2) Providing unequal procedural rights to a certain class of actors, easing their ability, through ISDS, to challenge regulatory measures negatively impacting their economic interests, while other individuals and entities continue to face relatively high legal and practical barriers to using litigation to protect and/or enhance public interest objectives. This Working Paper, adapted from the book chapter “Investment Treaties, Investor-State Dispute Settlement and Inequality: How International Rules and Institutions Can Exacerbate Domestic Disparities” (in José Antonio Ocampo, ed., International Rules and Inequality: Implications for Global Economic Governance (Columbia University Press), 2019-01), explores these channels in greater depth. It also calls for further research to explore how international investment governance could be enlisted to combat inequality, instead of embedding and inflaming it.

description: In the framework of the 3-3-1 model with neutral leptons, we have investigated the lepton-flavor-violating sources based on the Higgs mass spectrum which has two neutral Higgses identitied with corresponding ones in the Two-Higgs-Doublet model (THDM). On the $13~\mathrm{TeV}$ scale of the LHC, we point out the parameter space regions where the experimental limits of $e_i \rightarrow e_jγ$ decays are satisfied. These regions depend heavily on the mixing of exotic leptons but are predicted to have large $h^0_1\rightarrow μτ$ signals. We also show that $\mathrm{Br}(h^0_1\rightarrow μτ)$ can reach a value of $10^{-4}$.

description: Online learning algorithms are fast, memory-efficient, easy to implement, and applicable to many prediction problems, including classification, regression, and ranking. Several online algorithms were proposed in the past few decades, some based on additive updates, like the Perceptron, and some on multiplicative updates, like Winnow. A unifying perspective on the design and the analysis of online algorithms is provided by online mirror descent, a general prediction strategy from which most first-order algorithms can be obtained as special cases. We generalize online mirror descent to time-varying regularizers with generic updates. Unlike standard mirror descent, our more general formulation also captures second order algorithms, algorithms for composite losses and algorithms for adaptive filtering. Moreover, we recover, and sometimes improve, known regret bounds as special cases of our analysis using specific regularizers. Finally, we show the power of our approach by deriving a new second order algorithm with a regret bound invariant with respect to arbitrary rescalings of individual features.

description: Energy Conservation Theory of Second Language Acquisition (ECT-L2A; Han, Bao & Wiita, 2017), an interdisciplinary theory juxtaposing a physics perspective and an applied linguistics perspective, conceptualizes individuals’ ultimate attainment as a function of dynamic transformation of endogenous and exogenous energies throughout the learning process. ECT-L2A predicts, inter alia, (1) that beginning L2 learners should show stronger motivation than end-state learners, (2) that developing learners should show higher motivation than that of beginners, and (3) that beginning, developing, and end-state learners should exhibit similar profile in aptitude. These predictions were tested with 56 ESL learners. Correlation analyses were conducted on learners’ aptitude, motivation, years of study, and performance on a timed grammaticality judgment test. The results showed that: (1) with increase in proficiency and years of study, there was a decrease in motivation; (2) the effect of aptitude diminished as learners made progress towards the target language; (3) combined effect of aptitude and motivation correlated positively with the their L2 attainment, but its effects diminished as the proficiency level of the groups became more advanced.

description: This thesis refers to the study and presentation of ancient monuments restorations during the Italian Rule in Kos.  The  ancient  monuments  of  Kos  were  recorded, consolidated and restoredby  the  Italians  during  the period 1920–1940;a fact that contributed to their preservation.However, there are some weaknesses in the methods and principles of restorations conductedby the Italians. Those disadvantages have been studied with respect tothespecific time period, that is to say, with regard to the principles that were commonly followed for monumentrestorationin Italy duringthe first half of the 20th century. For a better understanding of this study, those principles are presented in brief. In addition, the text deals  with  the  particular  natural  and structural environment  of  Kos  in  order  to  understand  the historical background andconditions prevailingin Kos during this period.The  main  and  most  famous  monuments  of  the  island,  as  well  as  monuments  of  smaller  scale,  with  equally important interest as to the Italian interventionsare also presented.The study concludes in the evaluation of practices andmethods implemented by the Italians and attempts a more  general analysis of the  effectiveness  of thesemethods,as  to  contribute  to  the  safeguarding  ofthe monuments in the future.

description: Many astrophysical systems can only be accurately modelled when the behaviour of their baryonic gas components is well understood. The residual distribution (RD) family of partial differential equation (PDE) solvers produce approximate solutions to the corresponding fluid equations. We present a new implementation of the RD method. The solver efficiently calculates the evolution of the fluid, with up to second order accuracy in both time and space, across an unstructured triangulation, in both 2D and 3D. We implement a novel variable time stepping routine, which applies a drifting mechanism to greatly improve the computational efficiency of the method. We conduct extensive testing of the new implementation, demonstrating its innate ability to resolve complex fluid structures, even at very low resolution. We can resolve complex structures with as few as 3-5 resolution elements, demonstrated by Kelvin-Helmholtz and Sedov blast tests. We also note that we find cold cloud destruction time scales consistent with those predicted by a typical PPE solver, albeit the exact evolution shows small differences. The code includes three residual calculation modes, the LDA, N and blended schemes, tailored for scenarios from smooth flows (LDA), to extreme shocks (N), and both (blended). We compare our RD solver results to state-of-the-art solvers used in other astrophysical codes, demonstrating the competitiveness of the new approach, particularly at low resolution. This is of particular interest in large scale astrophysical simulations, where important structures, such as star forming gas clouds, are often resolved by small numbers of fluid elements.

description: To any manifold equipped with a higher degree closed form, one can associate an L-infinity algebra of local observables that generalizes the Poisson algebra of a symplectic manifold. Here, by means of an explicit homotopy equivalence, we interpret this L-infinity algebra in terms of infinitesimal autoequivalences of higher prequantum bundles. By truncating the connection data on the prequantum bundle, we produce analogues of the (higher) Lie algebras of sections of the Atiyah Lie algebroid and of the Courant Lie 2-algebroid. We also exhibit the L-infinity cocycle that realizes the L-infinity algebra of local observables as a Kirillov-Kostant-Souriau-type L-infinity extension of the Hamiltonian vector fields. When restricted along a Lie algebra action, this yields Heisenberg-like L-infinity algebras such as the string Lie 2-algebra of a semisimple Lie algebra.

description: Catalytic finance leverages limited amounts of scarce development-focused capital into much larger amounts of other capital, particularly private capital, towards projects with high development impact. In order to successfully implement catalytic finance transactions in a development finance context, a development bank must play the essential role of a policy entrepreneur, often sourcing catalytic capital and other resources in a highly customized manner to address specific financing challenges. This case study examines three innovative transactions designed by the Inter-American Development Bank (IDB) to address specific development financing challenges in the Latin America and Caribbean (LAC) region. These cases comprise risk reduction in the financing of geothermal energy, securitization of solar energy, and collective action to facilitate efficient and results-based investment in disease prevention. We examine the methods used in these transactions to decrease actual and perceived risk, and match appropriate sources of capital with pressing development needs. The broader lessons from these examples, when scaled up to similar situations, can facilitate the leveraging of private investment in the underdeveloped world that is many times larger than the available public capital. They all involve the curating of diverse sources of capital which would not be feasible in the absence of a mission-driven blended finance sponsor such as the IDB. These cases illustrate the crucial role played by the Office of Outreach and Partnerships within the IDB, whose task is to act as a resource mobilizer, blended finance sponsor and policy entrepreneur.

description: A model of the extent of wave driven overwash into fields of sea ice floes is proposed. The extent model builds on previous work modelling wave overwash of a single floe by regular waves by including irregular incoming waves and random floe fields. The model is validated against a laboratory experiment. It is then used to study the extent of wave overwash into marginal ice zones consisting of pancake and fragmented floe fields. The effects of wave conditions and floe geometry on predicted extents are investigated. Finally, the model is used to predict the wave overwash extent for the conditions observed during a winter (July) 2017 Antarctic voyage in which the sea surface was monitored by a stereo-camera system.

description: In spinor formalism, since any massless free-field spinor with spin higher than $1/2$ can be constructed with spin-1/2 spinors (Dirac-Weyl spinors) and scalars, we introduce a map between Weyl fields and Dirac-Weyl fields. We determine the corresponding Dirac-Weyl spinors in a given empty spacetime. Regarding them as basic units, other higher spin massless free-field spinors are then identified. Along this way, we find some hidden fundamental features related to these fields. In particular, for non-twisting vacuum Petrov type N solutions, we show that all higher spin massless free-field spinors can be constructed with one type of Dirac-Weyl spinor and the zeroth copy. Furthermore, we systematically rebuild the Weyl double copy for non-twisting vacuum type N and vacuum type D solutions. Moreover, we show that the zeroth copy not only connects the gravity fields with a single copy but also connects the degenerate Maxwell fields with the Dirac-Weyl fields in the curved spacetime, both for type N and type D cases. Besides, we extend the study to non-twisting vacuum type III solutions. We find a particular Dirac-Weyl scalar independent of the proposed map and whose square is proportional to the Weyl scalar. A degenerate Maxwell field and an auxiliary scalar field are then identified. Both of them play similar roles as the Weyl double copy. The result further inspires us that there is a deep connection between gravity theory and gauge theory.

description: Με την παρούσα διπλωματική εργασία επιχειρείται ένα σύνολο επεμβάσεων στη Β΄πλαζ Βούλας Αττικής με στόχο την αναβίωση της περιοχής και τη δημιουργία ενός παραλιακού σημείου συνάντησης, που θα επαναφέρει την σχέση του κατοίκου με τη θάλασσα. Η περιοχή μελέτης λειτουργούσε κατά τις δεκαετίες του ’70 και του ‘80 ως πλαζ του ΕΟΤ με λουτρικές εγκαταστάσεις και χρήσεις αναψυχής. Η εργασία αυτή έχει ως στόχο την επανένταξη της περιοχής στον αστικό ιστό και τη δημιουργία εγκαταστάσεων που θα απευθύνονται στους κατοίκους της ευρύτερης περιοχής, σε υφιστάμενα και νέα κτίρια. Πιο συγκεκριμένα, επαναπροσδιορίζονται οι προσβάσεις προς την πλαζ, τοποθετούνται κτίρια και χρήσεις πολιτισμού, ψυχαγωγίας, αθλητισμού και κολύμβησης, και διαμορφώνεται ο δημόσιος χώρος γύρω από αυτές.

description: Η ερευνητική εργασία πραγματεύεται την σχέση Μορφής και Περιεχομένου σε δύο σημαντικές στιγμές της φιλοσοφίας αυτές της αισθητικής θεωρίας του G.W.F. Hegel και της θεωρίας του στοχασμού του ‘έξω’του Michel Foucault. Η σχέση μορφής και περιεχομένου εξετάζεται, επίσης, μέσω της μετάβασης της φιλοσοφικής σκέψης από τη διαλεκτική θεωρία σ’ αυτή της διαφοράς. Το κείμενο αρθρώνεται σε τρεις ενότητες όπου αναλύονται οι δύο φιλοσοφικές θεωρίες και τέλος χαρακτηριστικά χωρικά παραδείγματα. Διερευνάται η σκέψη του Γερμανού φιλοσόφου G.W.F. Hegel στο πεδίο της αισθητικής όπου ορίζεται η σχέση μορφής και περιεχομένου στο σύστημα των τεχνών και αναλύεται διαλεκτικά. Στο πλαίσιο αυτό θα μελετηθούν οι βασικές αρχές της Αισθητικής του Hegel ξεκινώντας από την έννοια του «ωραίου της τέχνης» και την Ιδέα του ‘ωραίου’ η οποία πραγματώνεται μέσω του Απόλυτου Πνεύματος. Στη συνέχεια, αναπτύσσεται η σκέψη του Michel Foucault σε σχέση με την τοπολογική και όχι πλέον διαλεκτική ερμηνεία της σχέσης ανάμεσα σε δίπολα όπως το μέσα και το έξω, μορφή/ περιεχόμενο, βάθος /επιφάνεια προτείνοντας στη θέση της διαλεκτικής τη σχέση της διαφοράς. Τέλος, εντοπίζονται τα βασικά χαρακτηριστικά και οι διαφορές των δύο αυτών στάσεων μεταφέροντας την προβληματική τους στην χωρική κατανόηση των μεταβατικών σχέσεων του ‘κατωφλιού’ και στην χωρική και αισθητική ερμηνεία του τοπίου.

description: For many years now it has become conventional for theorists to argue that "space-time is doomed", with the difficulties in finding a quantum theory of gravity implying the necessity of basing a fundamental theory on something quite different than usual notions of space-time geometry. But what is this space-time geometry that is doomed? In this essay we'll explore how our understanding of four-dimensional geometry has evolved since Einstein, leading to new ideas about such geometry which may not be doomed at all.

description: We investigate the localization of low-energy single quasi-particle states in the 7/9-hybrid nanoribbon system in the presence of strong interactions and within a finite volume. We consider two scenarios, the first being the Hubbard model at half-filling and perform quantum Monte Carlo simulations for a range $U$ that includes the strongly correlated regime. In the second case we add a nearest-neighbor superconducting pairing $Δ$ and take the symmetric line limit, where $Δ$ is equal in magnitude to the hopping parameter $t$. In this limit the quasi-particle spectrum and wavefunctions can be directly solved for general onsite interaction $U$. In both cases we extract the site-dependent quasi-particle wavefunction densities and demonstrate that localization persists in these non-perturbative regimes under particular scenarios.

description: Although Earth is the only known planet on which plate tectonics operates, many small- and large-scale tectonic landforms indicate that deformational processes also occur on the other rocky planets. Although the mechanisms of deformation differ on Mercury, Venus, and Mars, the surface manifestations of their tectonics are frequently very similar to those found on Earth. Furthermore, tectonic processes invoked to explain deformation on Earth before the recognition of horizontal mobility of tectonic plates remain relevant for the other rocky planets. These connections highlight the importance of drawing analogies between the rocky planets for characterizing deformation of their lithospheres and for describing, applying appropriate nomenclature, and understanding the formation of their resulting tectonic structures. Here we characterize and compare the lithospheres of the rocky planets, describe structures of interest and where we study them, provide examples of how historic views on geology are applicable to planetary tectonics, and then apply these concepts to Mercury, Venus, and Mars.

description: Most real-world networks evolve over time. Existing literature proposes models for dynamic networks that are either unlabeled or assumed to have a single membership structure. On the other hand, a new family of Mixed Membership Stochastic Block Models (MMSBM) allows to model static labeled networks under the assumption of mixed-membership clustering. In this work, we propose to extend this later class of models to infer dynamic labeled networks under a mixed membership assumption. Our approach takes the form of a temporal prior on the model's parameters. It relies on the single assumption that dynamics are not abrupt. We show that our method significantly differs from existing approaches, and allows to model more complex systems --dynamic labeled networks. We demonstrate the robustness of our method with several experiments on both synthetic and real-world datasets. A key interest of our approach is that it needs very few training data to yield good results. The performance gain under challenging conditions broadens the variety of possible applications of automated learning tools --as in social sciences, which comprise many fields where small datasets are a major obstacle to the introduction of machine learning methods.
