description: Expressing gratitude is associated with increases in feelings of positive emotion. In a recent study, we found that writing a letter of gratitude, thanking a person for something they said or did in the past, was associated with an increase in positive affect. We also found that this effect was moderated by life satisfaction - the effect was only observed for participants with moderate and high levels of life satisfaction. This was an unregistered, exploratory study. It is now important that we replicate this finding, to show that it is a true effect and not something that we observed by chance. In the exploratory study, we also informed participants about the benefits of writing a gratitude letter - here, we aim to remove this information to investigate whether we can replicate the finding when these demand characteristics are removed.

description: We propose general separation procedures for generating cuts for the stable set polytope, inspired by a procedure by Rossi and Smriglio and applying a lifting method by Xavier and Campêlo. In contrast to existing cut-generating procedures, ours generate both rank and non-rank valid inequalities, hence they are of a more general nature than existing methods. This is accomplished by iteratively solving a lifting problem, which consists of a maximum weighted stable set problem on a smaller graph. Computational experience on DIMACS benchmark instances shows that the proposed approach may be a useful tool for generating cuts for the stable set polytope.
Evading Weinberg's no-go theorem to construct mass dimension one fermions: Constructing darkness

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Recent theoretical work reporting the construction of a new quantum field of spin one half fermions with mass dimension one requires that Weinberg's no go theorem must be evaded. Here we show how this comes about. The essence of the argument is to first define a quantum field with due care being taken in fixing the locality phases attached to each of the expansion coefficients. The second ingredient is to systematically construct the adjoint/dual of the field. The Feynman-Dyson propagator constructed from the vacuum expectation value of the field and its adjoint then yields the mass dimensionality of the field. For a quantum field constructed from a complete set of eigenspinors of the charge conjugation operator, with locality phases judiciously chosen, the Feynman-Dyson propagator has mass dimension one. The Lorentz symmetry is preserved, locality anticommutators are satisfied, without violating fermionic statistics as needed for the spin one half field.

description: Motivated by the physics of strings and branes, we develop a class of Markov chain Monte Carlo (MCMC) algorithms involving extended objects. Starting from a collection of parallel Metropolis-Hastings (MH) samplers, we place them on an auxiliary grid, and couple them together via nearest neighbor interactions. This leads to a class of "suburban samplers" (i.e., spread out Metropolis). Coupling the samplers in this way modifies the mixing rate and speed of convergence for the Markov chain, and can in many cases allow a sampler to more easily overcome free energy barriers in a target distribution. We test these general theoretical considerations by performing several numerical experiments. For suburban samplers with a fluctuating grid topology, performance is strongly correlated with the average number of neighbors. Increasing the average number of neighbors above zero initially leads to an increase in performance, though there is a critical connectivity with effective dimension d_eff ~ 1, above which "groupthink" takes over, and the performance of the sampler declines.

description: Der Einfluss der Fütterungsintensität auf das Wachstum von Ziegenlämmern. Ziel der vorliegenden Arbeit ist es, die Auswirkungen einer Milchrestriktion während der laktogenen Aufzucht von Ziegenlämmern sowie Mechanismen des kompensatorischen Wachstums nach dem Absetzen der Tiere zu untersuchen. Im Literaturteil werden das kompensatorische Wachstum, die Einflussfaktoren welche die Kompensationseffekte bestimmen, mögliche Ursachen sowie die Auswirkungen auf das Tier beschrieben. Der eigenen Untersuchung liegen die Daten aus zwei Fütterungsversuchen mit insgesamt 58 Ziegenlämmern der Rasse Bunte Deutsche Edelziege im Alter von 7 bis 165 Tagen zu Grunde. In einem 2 x 2 faktoriellen Versuchsansatz wurden zunächst die Auswirkung einer Milchrestriktion um 40 % und eine anschließende zeitweilige Futterrestriktion um 40 % auf die Lebendmasse-entwicklung, die Futteraufnahme, Futteraufwand die Entwicklung der Inneren Organe sowie die Körperzusammensetzung der Lämmer untersucht. Die Ergebnisse sind im Hinblick auf mögliche Ursachen der Kompensationseffekte diskutiert.
description: The influence of different feed levels on the growth performance of goat lambs. This study investigated the effect of a milk restriction of preweaned lambs as well as the effects of compensatory growth after weaning. The literature part gives a overview of factors, which effect compensatory growth rates as well as reasons for the compensation of a waight deficite. The present study was carried out in 2 feeding experiments with 58 goat lambs (Bunte deutsche Edelziege) during the age of 7 to 165 days. The experiment investigated the influence of a restriction of milk (40 %) on prewaened lambs. After weaning the effect of a food restriction (40 %) on growth performance, food intake, food converting rate, development of internal organs and body composition of goat lambs was investigated. The results and possible reasons for the compensation effect are discussed.

description: Die vorliegende Arbeit eröffnet einen weit über den „unmittelbaren“ Gegenstand Bildbeschreibung hinausweisenden allgemeinen theoretischen Horizont. Heiner Müllers Text wird als Fallstudie eines Umgangs mit dem antiken Mythos und in Hinblick auf seine Intertextualität weitgefächert untersucht. Die intensivierte Auseinandersetzung Müllers mit der Bildenden Kunst, besonders der Arbeitstechnik der Übermalung, welche sich in dem Stück Bildbeschreibung wiederfindet, wird aufgezeigt und anhand von Fallbeispielen aus der Bildenden Kunst in Zusammenhang gestellt. Die von Müller sorgfältig ausgelegten Zeichen werden durch ein close reading erschlossen: Auf der Grundlage der Prätexte und Bilder wird nach jenen Codes gesucht, die sich in Müllers Arbeiten in einer „Sprache, die niemand lesen kann“ auffinden und beschreiben lassen. Die Arbeit liefert Proben solcher Möglichkeiten der Annäherung an das Material. Der Untersuchungsbogen reicht von dem minoischen Totenkult bis zur japanischen Theatertradition des Nô-Theaters. Dabei wird über Exkurse zur Geschichtlichkeit der Mythenbilder, zur Kunst- und Filmgeschichte ein neues Erkenntnisfeld literaturwissenschaftlicher und geschichtsphilosophischer Erörterungen zum Werk Heiner Müllers eröffnet.
description: In this paper a new theoretical horizon is opened that goes far beyond a mere analysis of Mueller’s “Bildbeschreibung”. The text though is meticulously examined in terms of its intertextuality and serves mainly as a case study of a new approach to the ancient myth. Mueller’s work has a strong affinity to the visual arts, especially the “overpainting” technique, which is thoroughly used in “Bildbeschreibung”. In this paper this particular relationship is highlighted and through the use of specific examples from the visual arts is made explicit and put into context. Mueller’s carefully selected “signs” are decodified through a close reading. There is the attempt to find the codes of Mueller’s oeuvre, using the prototypical texts and images. These codes are located and described in “a language that no one can read”. The present paper provides concrete proof that such an approach to the material is possible. The analytical framework ranges from the Minoan death cult to the traditional Japanese No-theatre. The paper also makes use of the historicity of the mythical imagery and of elements of the history of art and cinematographic studies. The result is a new theoretical field into Heiner Mueller’s work that is mainly anchored in the disciplines of literary studies, history and philosophy.

description: Stationarity is a cornerstone property that facilitates the analysis and processing of random signals in the time domain. Although time-varying signals are abundant in nature, in many practical scenarios the information of interest resides in more irregular graph domains. This lack of regularity hampers the generalization of the classical notion of stationarity to graph signals. The contribution in this paper is twofold. Firstly, we propose a definition of weak stationarity for random graph signals that takes into account the structure of the graph where the random process takes place, while inheriting many of the meaningful properties of the classical definition in the time domain. Our definition requires that stationary graph processes can be modeled as the output of a linear graph filter applied to a white input. We will show that this is equivalent to requiring the correlation matrix to be diagonalized by the graph Fourier transform. Secondly, we analyze the properties of the power spectral density and propose a number of methods to estimate it. We start with nonparametric approaches, including periodograms, window-based average periodograms, and filter banks. We then shift the focus to parametric approaches, discussing the estimation of moving-average (MA), autoregressive (AR) and ARMA processes. Finally, we illustrate the power spectral density estimation in synthetic and real-world graphs.

description: Inspired by the 750 GeV diphoton state recently reported by ATLAS and CMS, we propose a U(1)_{B-L} extension of the MSSM which predicts the existence of four spin zero resonance states that are degenerate in mass in the supersymmetric limit. Vector-like fields, a gauge singlet field, as well as the MSSM Higgsinos are prevented from acquiring arbitrary large masses by a U(1) R-symmetry. Indeed, these masses can be considerably lighter than the Z' gauge boson mass. Depending on kinematics the resonance states could decay into right handed neutrinos and sneutrinos, and/or MSSM Higgs fields and Higgsinos with total decay widths in the multi-GeV range.

description: We prove that estimating the ground state energy of a translationally-invariant, nearest-neighbour Hamiltonian on a 1D spin chain is QMAEXP-complete, even for systems of low local dimension (roughly 40). This is an improvement over the best previously-known result by several orders of magnitude, and it shows that spin-glass-like frustration can occur in translationally-invariant quantum systems with a local dimension comparable to the smallest-known non-translationally-invariant systems with similar behaviour. While previous constructions of such systems rely on standard models of quantum computation, we construct a new model that is particularly well-suited for encoding quantum computation into the ground state of a translationally-invariant system. This allows us to shift the proof burden from optimizing the Hamiltonian encoding a standard computational model to proving universality of a simple model. Previous techniques for encoding quantum computation into the ground state of a local Hamiltonian allow only a linear sequence of gates, hence only a linear (or nearly linear) path in the graph of all computational states. We extend these techniques by allowing significantly more general paths, including branching and cycles, thus enabling a highly efficient encoding of our computational model. However, this requires more sophisticated techniques for analysing the spectrum of the resulting Hamiltonian. To address this, we introduce a framework of graphs with unitary edge labels. After relating our Hamiltonian to the Laplacian of such a unitary labelled graph, we analyse its spectrum by combining matrix analysis and spectral graph theory techniques.

This formula is based on a combinatorial model of classical crystals called spinor model. We show that our formulas extend in a bijective way various stable branching rules for classical groups to arbitrary highest weights, including the Littlewood restriction rules.

description: Label embedding (LE) is an important family of multi-label classification algorithms that digest the label information jointly for better performance. Different real-world applications evaluate performance by different cost functions of interest. Current LE algorithms often aim to optimize one specific cost function, but they can suffer from bad performance with respect to other cost functions. In this paper, we resolve the performance issue by proposing a novel cost-sensitive LE algorithm that takes the cost function of interest into account. The proposed algorithm, cost-sensitive label embedding with multidimensional scaling (CLEMS), approximates the cost information with the distances of the embedded vectors by using the classic multidimensional scaling approach for manifold learning. CLEMS is able to deal with both symmetric and asymmetric cost functions, and effectively makes cost-sensitive decisions by nearest-neighbor decoding within the embedded vectors. We derive theoretical results that justify how CLEMS achieves the desired cost-sensitivity. Furthermore, extensive experimental results demonstrate that CLEMS is significantly better than a wide spectrum of existing LE algorithms and state-of-the-art cost-sensitive algorithms across different cost functions.

description: The objects of study of this paper are communication channels in which the dominant type of noise are symbol shifts, the main motivating examples being timing and bit-shift channels. Two channel models are introduced and their zero-error capacities and zero-error-detection capacities determined by explicit constructions of optimal codes. Model A can be informally described as follows: 1) The information is stored in an $ n $-cell register, where each cell is either empty or contains a particle of one of $ P $ possible types, and 2) due to the imperfections of the device each of the particles may be shifted several cells away from its original position over time. Model B is an abstraction of a single-server queue: 1) The transmitter sends packets from a $ P $-ary alphabet through a queuing system with an infinite buffer and a First-In-First-Out (FIFO) service procedure, and 2) each packet is being processed by the server for a random number of time slots. More general models including additional types of noise that the particles/packets can experience are also studied, as are the continuous-time versions of these problems.

description: This thesis consists of a summary of two related research directions. First, the close study of the cohomology of stable vector bundles on the projective plane, and second, the attempt to extend the results and computations possible on on the projective plane via exceptional bundles to three-dimensional projective space. We give a rapid but readable introduction to helix theory, which is the systematic study of exceptional bundles on projective spaces. Using helix theory, we introduce the theory of stable vector bundles on the projective plane, and reproduce recent results of the author and collaborators the Brill-Noether theory of moduli spaces of higher rank vector bundles on the projective plane. Finally, we reproduce the results of the author on constructive exceptional bundles on three-dimensional projective space.

description: Noninteracting bosons were proposed to be used for a demonstration of quantum-computing supremacy in a boson-sampling setup. A similar demonstration with fermions would require that the fermions are initially prepared in an entangled state. I suggest that pairwise entanglement of fermions would be sufficient for this purpose. Namely, it is shown that computing multi-particle scattering amplitudes for fermions entangled pairwise in groups of four single-particle states is #P hard. In linear algebra, such amplitudes are expressed as exterior products of two-forms of rank two. In particular, a permanent of a NxN matrix may be expressed as an exterior product of N^2 two-forms of rank two in dimension 2N^2, which establishes the #P-hardness of the latter.

description: We introduce the network model as a formal psychometric model, conceptualizing the covariance between psychometric indicators as resulting from pairwise interactions between observable variables in a network structure. This contrasts with standard psychometric models, in which the covariance between test items arises from the influence of one or more common latent variables. Here, we present two generalizations of the network model that encompass latent variable structures, establishing network modeling as parts of the more general framework of Structural Equation Modeling (SEM). In the first generalization, we model the covariance structure of latent variables as a network. We term this framework Latent Network Modeling (LNM) and show that, with LNM, a unique structure of conditional independence relationships between latent variables can be obtained in an explorative manner. In the second generalization, the residual variance-covariance structure of indicators is modeled as a network. We term this generalization Residual Network Modeling (RNM) and show that, within this framework, identifiable models can be obtained in which local independence is structurally violated. These generalizations allow for a general modeling framework that can be used to fit, and compare, SEM models, network models, and the RNM and LNM generalizations. This methodology has been implemented in the free-to-use software package lvnet, which contains confirmatory model testing as well as two exploratory search algorithms: stepwise search algorithms for low-dimensional datasets and penalized maximum likelihood estimation for larger datasets. We show in simulation studies that these search algorithms performs adequately in identifying the structure of the relevant residual or latent networks. We further demonstrate the utility of these generalizations in an empirical example on a personality inventory dataset.

description: Axion-like particles (ALPs) can induce localised oscillatory modulations in the spectra of photon sources passing through astrophysical magnetic fields. Ultra-deep Chandra observations of the Perseus cluster contain over $5 \times 10^5$ counts from the AGN of the central cluster galaxy NGC1275, and represent a dataset of extraordinary quality for ALP searches. We use this dataset to search for X-ray spectral irregularities from the AGN. The absence of irregularities at the O(30%) level allows us to place leading constraints on the ALP-photon mixing parameter $g_{aγγ} \lesssim 1.4 - 4.0 \times 10^{-12} {\rm GeV}^{-1}$ for $m_a \lesssim 10^{-12}$ eV, depending on assumptions on the magnetic field realisation along the line of sight.

The problems of this research are how Edmodo is implemented by the teachers in learning English as foreign language (EFL) in order to gain the better results of students learning achievement and what the problems around using Edmodo are found and solved by the teachers. It is a classroom action research based on qualitative-research. Research’s data is collected by doing class observation, filling the questionnaire, and test in two cycles. The first cycle results the average score that students can accomplish is 44.38 points which is below from the standard of minimum accomplishment (SMA) that is 75 points and there are only 12% of the students can accomplish the test. By applying Edmodo in the second cycle, the average mark of the students is touching 82.61 points with the conclusion that Edmodo succeed increases students’ achievements. The difficulties that are encountered in applying Edmodo in digital class are the availability of the hardware from the internet infrastructure to personal computer or smartphone of the students and the proficiency of students and teachers in using Edmodo.

description: Over the past half-century, the empirical finance community has produced vast literature on the advantages of the equally weighted S\&P 500 portfolio as well as the often overlooked disadvantages of the market capitalization weighted Standard and Poor's (S\&P 500) portfolio (see \cite{Bloom}, \cite{Uppal}, \cite{Jacobs}, \cite{Treynor}). However, portfolio allocation based on Tukey's transformational ladde have, rather surprisingly, remained absent from the literature. In this work, we consider the S\&P 500 portfolio over the 1958-2015 time horizon weighted by Tukey's transformational ladder (\cite{Tukey2}): $1/x^2,\,\, 1/x,\,\, 1/\sqrt{x},\,\, \text{log}(x),\,\, \sqrt{x},\,\, x,\,\, \text{and} \,\, x^2$, where $x$ is defined as the market capitalization weighted S\&P 500 portfolio. Accounting for dividends and transaction fees, we find that the 1/$x^2$ weighting strategy produces cumulative returns that significantly dominates all other portfolios, achieving a compound annual growth rate of 18\% over the 1958-2015 horizon. Our story is furthered by a startling phenomenon: both the cumulative and annual returns of the $1/x^2$ weighting strategy are superior to those of the $1/x$ weighting strategy, which are in turn superior to those of the 1/$\sqrt{x}$ weighted portfolio, and so forth, ending with the $x^2$ transformation, whose cumulative returns are the lowest of the seven transformations of Tukey's transformational ladder. The order of cumulative returns precisely follows that of Tukey's transformational ladder. To the best of our knowledge, we are the first to discover this phenomenon.

description: We present a new framework for the modelling of hard diffraction in pp and ppbar collisions. It starts from the the approach pioneered by Ingelman and Schlein, wherein the single diffractive cross section is factorized into a Pomeron flux and a Pomeron PDF. To this it adds a dynamically calculated rapidity gap survival factor, derived from the modelling of multiparton interactions. This factor is not relevant for diffraction in ep collisions, giving non-universality between HERA and Tevatron diffractive event rates. The model has been implemented in Pythia 8 and provides a complete description of the hadronic state associated with any hard single diffractive process. Comparisons with ppbar and pp data reveal improvement in the description of single diffractive events.

Our work not only extends the set of known memcapacitive and meminductive systems to qubit-based quantum devices but also highlights their unique properties potentially useful for future technological applications.

Publisher: name: Zenodo
Year: 2024

description: Purpose: Disruptive technologies (AI, IoT, etc) unlock new frontiers of data-centric innovation. This increases the computational needs, pushing more and more companies into the HPC space. However, although HPC is a key tool for processing and analysing the constantly growing volume of data across numerous application areas many companies remain reluctant to use HPC and move their HPC workloads to the cloud, which may be attributed to the inadequate understanding about HPC and its potential benefits, cost, security and performance aspects. At the same time, existing HPC training, mainly focus on the research and academic community, thus creating a gap in the provision of industrial HPC training and addressing the supercomputing knowledge skills of enterprises.

Methods: Towards this aim, this paper presents an example of “massively” co-created education and training HPC module, namely anHPC NOOC (Nano Open Online Course), targeting industrial learners. This open, agile co-creation approach incorporates key components of the European HPC ecosystem and beyond, aiming to offer aparadigm for success in the democratisation of HPC knowledge, and the co-creation of educational value aiming to reach a wide impact (i.e., educational, technological, innovation, economic impact, etc).

Results: The proposed HPC NOOC has been designed in an agile format so as to enable its ongoing evolution and expansion across emerging themes and indicative success stories across Europe and the world. 

Conclusion: Acknowledging the importance of HPC as a strategic investment for Europe and the world, this paper, aims to contribute to the democratisation of HPC training for industry and narrowing the gap between HPC adoption for micro, small and medium sized enterprises is important in order to reap the benefits of HPC innovations.

We show that $CCD(K,N)$ provides necessary and sufficient conditions for the underlying graph to satisfy a sharp global Poincaré inequality which in turn translates to a sharp lower bound for the first eigenvalues of these graphs. Another application of the conical curvature-dimension analysis is finding a sharp estimate on the curvature of complete graphs.

description: The canonical trace and the Wodzicki residue on classical pseudodifferential operators on a closed manifold are characterised by their locality and shown to be preserved under lifting to the universal covering as a result of their local feature. As a consequence, we lift a class of spectral $ζ$-invariants using lifted defect formulae which express discrepancies of $ζ$-regularised traces in terms of Wodzicki residues. We derive Atiyah's $L^2$-index theorem as an instance of the $\mathbb Z_2$-graded generalisation of the canonical lift of spectral $ζ$-invariants and we show that certain lifted spectral $ζ$-invariants for geometric operators are integrals of Pontryagin and Chern forms.

description: The step-growth polymerisation of a mixture of arbitrary-functional monomers is viewed as a time-continuos random graph process with degree bounds that are not necessarily the same for different vertices. The sequence of degree bounds acts as the only input parameter of the model. This parameter entirely defines the timing of the phase transition. Moreover, the size distribution of connected components features a rich temporal dynamics that includes: switching between exponential and algebraic asymptotes and acquiring oscillations. The results regarding the phase transition and the expected size of a connected component are obtained in a closed form. An exact expression for the size distribution is resolved up to the convolution power and is computable in subquadratic time. The theoretical results are illustrated on a few special cases, including a comparison with Monte Carlo simulations.

description: Bisherige Methoden der Haplotyp-Block-Definition zielen entweder auf abwesende Rekombinationsereignisse oder eine effiziente Beschreibung genomischer Variation. Die vorliegende Arbeit definiert Blöcke von Single Nucleotide Polymorphisms (SNP) als Gebiete erhöhten Kopplungsungleichgewichtes (LD). Für dieses Ziel wird ein neues, entropie-basiertes Maß für LD zwischen multiplen Markern/Loci (Normalized Entropy Difference) entwickelt und als eine Multilocus-Erweiterung des paarweisen Maßes r2 charakterisiert. Ein zugehöriger Algorithmus für die Block-Definition wird vorgeschlagen. Seine Evaluierung an einem Datensatz des menschlichen Chromosoms 12 vom Internationalen Haplotype Map Projekt zeigt die Nützlichkeit der abgeleiteten Blöcke in Hinblick auf verschiedene Eigenschaften, einschließlich ihrer chromosomalen Coverage und der Anzahl sowie des Anteils der häufigen Block-Haplotypen. Der wesentliche Einfluß der SNP-Dichte auf die zu entdeckenden LD- und Blockstrukturen wird demonstriert. Der Erfolg von Assoziationsstudien in komplexen Erkrankungen mit Block-Haplotypen als multiallelischen Markern wird davon abhängen, ob die Common Variants/Common Diseases (CV/CD) Hypothese für solche Erkrankungen erfüllt ist.
description: Current approaches to haplotype block definition target either absent recombination events or the efficient description of genomic variation. This thesis aims to define blocks of single nucleotide polymorphisms (SNP) as areas of elevated linkage disequilibrium (LD). To this end, a new entropy-based measure for LD between multiple markers/loci, the Normalized Entropy Difference, is developed and is characterized as a multilocus extension of the pairwise measure r2. A corresponding algorithm for the block definition is proposed. Its evaluation on a data set of human chromosome 12 from the International Haplotype Map project proves the usefulness of the derived blocks with respect to several features, including their chromosomal coverage and the number and portion of common block haplotypes. The critical role of the SNP density for detectable LD and block structure is demonstrated. The success of association studies in common diseases with block haplotypes serving as multi-allelic markers will depend on whether the Common Variants/Common Diseases (CV/CD) hypothesis holds true for those diseases.

description: We propose a systematic magnetic-flux-free approach to detect, manipulate and braid Majorana fermions in a semiconductor nanowire-based topological Josephson junction by utilizing the Majorana spin degree of freedom. We find an intrinsic $π$-phase difference between spin-triplet pairings enforced by the Majorana zeros modes (MZMs) at the two ends of a one-dimensional spinful topological superconductor. This $π$-phase is identified to be a spin-dependent superconducting phase, referred to as the spin-phase, which we show to be tunable by controlling spin-orbit coupling strength via electric gates. This electric controllable spin-phase not only affects the coupling energy between MZMs but also leads to a fractional Josephson effect in the absence of any applied magnetic flux, which enables the efficient topological qubit readout. We thus propose an all-electrically controlled superconductor-semiconductor hybrid circuit to manipulate MZMs and to detect their non-Abelian braiding statistics properties. Our work on spin properties of topological Josephson effects potentially opens up a new thrust for spintronic applications with Majorana-based semiconductor quantum circuits.

description: Let $(\mathcal{M},g)$ be a compact Riemannian manifold of dimension $N\geq 2$. We prove the existence of a family $(Ω_\varepsilon)_{\varepsilon\in (0,\varepsilon_0)}$ of self-Cheeger sets in $(\mathcal{M},g)$ . The domains $Ω_\varepsilon\subset\mathcal{M}$ are perturbations of geodesic balls of radius $\varepsilon$ centered at $p \in \mathcal{M}$, and in particular, if $p_0$ is a non-degenerate critical point of the scalar curvature of $g$, then the family $(\partial Ω_\varepsilon)_{\varepsilon \in (0,\varepsilon_0)}$ constitutes a smooth foliation of a neighborhood of $p_0$.

description: Κύριος στόχος της διπλωματικής εργασίας είναι η υλοποίηση μίας διαδικτυακής εφαρμογής, με την χρήση τεχνολογιών Web 2.0, συνεπικουρούμενες από τεχνολογίες Web 1.0 και τον τρόπο που αυτές αλληλοεπιδρούν μεταξύ τους. Η λειτουργία της εφαρμογής είναι διττή, καθώς ο χρήστης μπορεί να εγγραφή με δύο τρόπους. Είτε ως «σεφ» είτε ως «πελάτης». Κάνοντας εγγραφή ως «σεφ», ο χρήστης έχει τη δυνατότητα δημιουργίας προσωπικού προφίλ βάσει των μαγειρικών δεξιοτήτων του και το είδος της κουζίνας που αντιπροσωπεύει, εμπλουτίζοντάς το με φωτογραφικό υλικό. Με την εγγραφή του ως «πελάτης», δημιουργεί προσωπικό προφίλ με τα βασικά στοιχεία επικοινωνίας, έχοντας τη δυνατότητα εύρεσης μαγειρικού προσωπικού, βάσει κριτηρίων επιλογής, το οποίο είναι ήδη εγγεγραμμένο στην πλατφόρμα. Ο χρήστης μπορεί να επικοινωνήσει μαζί με τον σεφ μέσω των στοιχείων επικοινωνίας του και να κάνει κράτηση μέσω του Book Section. Για τη δημιουργία και τη δόμηση της πλατφόρμας χρησιμοποιήθηκαν 5 βασικές τεχνολογίες. Η πρώτη είναι η HTML5, η οποία χρησιμοποιήθηκε για την περιγραφή της δομής της εφαρμογής, με χρήση ετικετών (tags). Στην συνέχεια η CSS3, η οποία ορίζει την εμφάνιση και τη διάταξη των στοιχείων της πλατφόρμας, όπως το χρώμα, τη γραμματοσειρά, τα περιθώρια, τις διαστάσεις, τα σχήματα κτλ. Τρίτη βασική τεχνολογία που χρησιμοποιείται για την ανάπτυξη διαδικτυακών εφαρμογών, σε συνδυασμό με την HTML και την CSS είναι η Javascript, η οποία προσθέτει δυναμικότητα αλλά και ζωντάνια στην ίδια την πλατφόρμα. Επιπλέον, για την προσθήκη δυναμικότητας στην εφαρμογή έγινε η χρήση της PHP 8.0 σε συνδυασμό με την mySQL 8.0, η οποία βοήθησε στην υλοποίηση της βάσης δεδομένων. Αποτελείται από 4 πίνακες, στους οποίους αποθηκεύονται όλα τα δεδομένα, όπως τα στοιχεία εγγραφής κάθε χρήστη, καθώς και πληροφορίες για το υλικό με το οποίο ο σεφ εμπλουτίζει το προφίλ του, αλλά και δεδομένα για τα ραντεβού που κλείνονται μέσω της πλατφόρμας, μεταξύ πελάτη και σεφ. Η ανάπτυξη και ο προγραμματισμός της εφαρμογής έγινε μέσω του Visual Studio Code.
