description: Sterile neutrinos with masses in the keV range are well-motivated extensions to the Standard Model that could explain the observed neutrino masses while also making up the dark matter (DM) of the Universe. If sterile neutrinos are DM then they may slowly decay into active neutrinos and photons, giving rise to the possibility of their detection through narrow spectral features in astrophysical X-ray data sets. In this work, we perform the most sensitive search to date for this and other decaying DM scenarios across the mass range from 5 to 16 keV using archival XMM-Newton data. We reduce 547 Ms of data from both the MOS and PN instruments using observations taken across the full sky and then use this data to search for evidence of DM decay in the ambient halo of the Milky Way. We determine the instrumental and astrophysical baselines with data taken far away from the Galactic Center, and use Gaussian Process modeling to capture additional continuum background contributions. No evidence is found for unassociated X-ray lines, leading us to produce the strongest constraints to date on decaying DM in this mass range.

description: Following Baxter's method of producing Q_{72}-operator, we construct the Q-operator of the root-of-unity eight-vertex model for the crossing parameter $η= \frac{2m K}{N}$ with odd $N$ where Q_{72} does not exist. We use this new Q-operator to study the functional relations in the Fabricius-McCoy comparison between the root-of-unity eight-vertex model and the superintegrable N-state chiral Potts model. By the compatibility of the constructed Q-operator with the structure of Baxter's eight-vertex (solid-on-solid) SOS model, we verify the set of functional relations of the root-of-unity eight-vertex model using the explicit form of the Q-operator and fusion weights of SOS model.

description: This paper describes in detail the implementation of a finite element technique for solving the compressible Navier-Stokes equations that is provably robust and demonstrates excellent performance on modern computer hardware. The method is second-order accurate in time and space. Robustness here means that the method is proved to be invariant domain preserving under the hyperbolic CFL time step restriction, and the method delivers results that are reproducible. The proposed technique is shown to be accurate on challenging 2D and 3D realistic benchmarks.

description: The results of simultaneous multifrequency observations of giant radio pulses from the Crab pulsar, PSR B0531+21, at 23, 111, and 600 MHz are presented and analyzed. Giant pulses were detected at a frequency as low as 23 MHz for the first time. Of the 45 giant pulses detected at 23 MHz, 12 were identified with counterparts observed simultaneously at 600 MHz. Of the 128 giant pulses detected at 111 MHz, 21 were identified with counterparts observed simultaneously at 600 MHz. The spectral indices for the power-law frequency dependence of the giant-pulse energies are from -3.1 to -1.6. The mean spectral index is -2.7 +/- 0.1 and is the same for both frequency combinations (600-111 MHz and 600-23 MHz). The large scatter in the spectral indices of the individual pulses and the large number of unidentified giant pulses suggest that the spectra of the individual giant pulses do not actually follow a simple power law. The observed shapes of the giant pulses at all three frequencies are determined by scattering on interstellar plasma irregularities. The scatter broadening of the pulses and its frequency dependence were determined as tau_sc=20*(f/100)^(-3.5 +/- 0.1) ms, where the frequency f is in MHz.

description: Recently, there has been a lot of attention devoted to resolving the quantum corrections to the Bekenstein-Hawking entropy of the black hole. In particular, the coefficient of the logarithmic term in the black hole entropy correction has been of great interest. In this paper, the black hole is corresponded to a canonical ensemble in statistics by radiant spectrum, resulted from the black hole tunneling effect studies and the partition function of ensemble is derived. Then the entropy of the black hole is calculated. When the first order approximation is taken into account, the logarithmic term of entropy correction is consistent with the result of the generalized uncertainty principle. In our calculation, there are no uncertainty factors. The prefactor of the logarithmic correction and the one if fluctuation is considered are the same. Our result shows that if the thermal capacity is negative, there is no divergent term. We provide a general method for further discussion on quantum correction to Bekenstein-Hawking entropy. We also offer a theoretical basis for comparing string theory and loop quantum gravitaty and deciding which one is more reliable.

description: This paper deals with the quasistatic crack growth of a homogeneous elastic brittle thin film. It is shown that the quasistatic evolution of a three-dimensional cylinder converges, as its thickness tends to zero, to a two-dimensional quasistatic evolution associated with the relaxed model. Firstly, a $Γ$-convergence analysis is performed with a surface energy density which does not provide weak compactness in the space of Special Functions of Bounded Variation. Then, the asymptotic analysis of the quasistatic crack evolution is presented in the case of bounded solutions that is with the simplifying assumption that every minimizing sequence is uniformly bounded in $L^\infty$.

description: The OPERA neutrino detector at the underground Gran Sasso Laboratory (LNGS) was designed to perform the first detection of neutrino oscillations in appearance mode, through the study of nu_mu to nu_tau oscillations. The apparatus consists of a lead/emulsion-film target complemented by electronic detectors. It is placed in the high-energy, long-baseline CERN to LNGS beam (CNGS) 730 km away from the neutrino source. In August 2006 a first run with CNGS neutrinos was successfully conducted. A first sample of neutrino events was collected, statistically consistent with the integrated beam intensity. After a brief description of the beam and of the various sub-detectors, we report on the achievement of this milestone, presenting the first data and some analysis results.

description: The scope of this thesis was to initially provide a bibliographic review of the research that has already taken place in regards to project management and specific techniques, such as the critical path method, program evaluation and review technique, as well as the activity crashing. Furthermore, the scope of the thesis was to approach theoretically project management and finally to apply the above techniques to the management of a particular project. In particular, it was attempted a theoretical approach to basic concepts, such as: project, project management, project manager, success factors, project management benefits, management methods, techniques and tools, Gantt charts, critical path, program evaluation and crash activity. In the practical part of the thesis, we applied the critical path method / program evaluation and review technique, as well as the activity crashing in the management of the renovation of an apartment in Thessaloniki and then we compared our results with those we got from the architectural office, which used no project management approach.

description: In this paper we consider the influence of relativistic rotation on the confinement/deconfinement transition in gluodynamics within lattice simulation. We perform the simulation in the reference frame which rotates with the system under investigation, where rotation is reduced to external gravitational field. To study the confinement/deconfinement transition the Polyakov loop and its susceptibility are calculated for various lattice parameters and the values of angular velocities which are characteristic for heavy-ion collision experiments. Different types of boundary conditions (open, periodic, Dirichlet) are imposed in directions, orthogonal to rotation axis. Our data for the critical temperature are well described by a simple quadratic function $T_c(Ω)/T_c(0) = 1 + C_2 Ω^2$ with $C_2>0$ for all boundary conditions and all lattice parameters used in the simulations. From this we conclude that the critical temperature of the confinement/deconfinement transition in gluodynamics increases with increasing angular velocity. This conclusion does not depend on the boundary conditions used in our study and we believe that this is universal property of gluodynamics.

Για την εκπόνηση της εργασίας χρησιμοποιήθηκε ένας μικρός πλωτήρας, χαμηλού κόστους, με ενσωματωμένο Γεωδαιτικό Δέκτη GNSS που συλλέγει ανεξάρτητα δεδομένα συνεχών μετρήσεων. Με τον τρόπο αυτό παρείχε πληροφορίες κινηματικής θέσης κατά τη διάρκεια των μετρήσεων. Η βασική ιδέα είναι να ενσωματωθούν οι λύσεις με χρήση διαφορετικών τεχνικών προσδιορισμού θέσης και η σύγκριση τους με διαφορετικά λογισμικά. Επιπλέον, αναλύθηκε η ικανότητα υπολογισμού των υψών των κυμάτων από τις μετρήσεις του δέκτη. Στα κεφάλαια που ακολουθούν, πραγματοποιείται συνοπτική ανάλυση του θεωρητικού υποβάθρου που χρησιμοποιήθηκε, περιγραφή των χρησιμοποιημένων σεναρίων λαμβάνοντας υπόψη τα διαθέσιμα δεδομένα, καθώς επίσης ανάλυση και σχολιασμός των αποτελεσμάτων για την περιοχή μελέτης.

Σαφώς μία πληθώρα όμοιων συσκευών διασκορπισμένες στον θαλάσσιο Ελλαδικό χώρο θα μπορούσε να προσφέρει σημαντικές πληροφορίες στην επιστημονική κοινότητα σε θέματα σχετικά με εφαρμογές των επιστημών της θάλασσας.
description: This master thesis was elaborated within the framework of the Postgraduate Program of Studies "Geoinformatics" of the School of Rural and Surveying Engineering of the Aristotle University of Thessaloniki. The master thesis refers to the analysis of sea surface heights from a low-cost buoy, whose main payload was a built-in GNSS Geodetic Receiver with a choke-ring antenna. The dedicated buoy collects independent continuous high-rate sea state observations, while consequently a dedicated post-processing analysis of the collected data is carried out. In this way, it provides kinematic information during the measurements. The basic idea is to integrate solutions using different positioning techniques and comparing them with a variety of software. Furthermore, the ability to calculate wave heights from receiver measurements was analyzed. In the following chapters, a brief analysis of the theoretical background used, a description of the used scenarios taking into account the data provided, as well as an analysis and annotation of the results for the study area are made. From the analysis of the result finally, we come to the conclusion that this methodology can be used with absolute certainty and reliability in corresponding applications. A number of similar systems could be scattered in the sea of Greece and could provide important information to the scientific community, related to applications of marine sciences.
Resonant interactions of nonlinear water waves in a finite basin

description: We study exact four-wave resonances among gravity water waves in a square box with periodic boundary conditions. We show that these resonant quartets are linked with each other by shared Fourier modes in such a way that they form independent clusters. These clusters can be formed by two types of quartets: (1) {\it angle-resonances} which cannot directly cascade energy but which can redistribute it among the initially excited modes and (2) {\it scale-resonances} which are much more rare but which are the only ones that can transfer energy between different scales. We find such resonant quartets and their clusters numerically on the set of 1000 x 1000 modes, classify and quantify them and discuss consequences of the obtained cluster structure for the wavefield evolution. Finite box effects and associated resonant interaction among discrete wave modes appear to be important in most numerical and laboratory experiments on the deep water gravity waves, and our work is aimed at aiding the interpretation of the experimental and numerical data.

description: We theoretically study macroscopic quantum entanglement in two superconducting flux qubits. To manipulate the state of two flux qubits, a Josephson junction is introduced in the connecting loop coupling the qubits. Increasing the coupling energy of the Josephson junction makes it possible to achieve relatively strong coupling between the qubits, causing two-qubit tunneling processes even dominant over the single-qubit tunneling process in the states of two qubits. It is shown that due to the two-qubit tunneling processes both the ground state and excited state of the coupled flux qubits can be a Bell type state, maximally entangled. The parameter regimes for the Bell states are discussed in terms of magnetic flux and Josephson coupling energies.

description: It is argued that accretion discs in young stellar objects may have hot coronae that are heated by magnetic reconnection. This is a consequence of the magneto-rotational instability driving turbulence in the disc. Magnetic reconnection away from the midplane leads to heating of the corona which, in turn, contributes to driving disc winds.

description: Η έγκαιρη διάγνωση και αντιμετώπιση του καρκίνου αποτελεί μια τεράστια πρόκληση για την ερευνητική κοινότητα, καθώς παραμένει μια από τις σημαντικότερες αιτίες θανάτου παγκοσμίως. Διάφορες μέθοδοι θεραπείας έχουν χρησιμοποιηθεί μέχρι σήμερα, οι σημαντικότερες από τις οποίες είναι η εγχειρητική αφαίρεση του όγκου, η ακτινοθεραπεία και η χημειοθεραπεία. Το αντικείμενο μελέτης της παρούσας εργασίας αγγίζει μια ιδιαίτερη προσέγγιση στα πλαίσια της προσπάθειας αντιμετώπισης της πάθησης του καρκίνου με χημειοθεραπεία. Πιο συγκεκριμένα, εκμεταλλεύεται τις καινούριες προοπτικές που προσφέρει η νανοτεχνολογία στη φαρμακευτική τεχνολογία, κι έχει σκοπό την ανάπτυξη φαρμακευτικού σκευάσματος με χρήση χαμηλότερων συγκεντρώσεων της αντικαρκινικής δραστικής, μειώνοντας έτσι τις πολύ σοβαρές παρενέργειες της χημειοθεραπείας (καταστροφή υγιών κυττάρων), αυξάνοντας, όμως, παράλληλα την βιοθεσιμότητα και άρα την αποτελεσματικότητά της. Για το λόγο αυτό, παρασκευάστηκαν πολυμερικοί νανοφορείς (τύπου core-shell), στους οποίους ενθυλακώθηκε το αντικαρκινικό φάρμακο paclitaxel καθώς και μαγνητικά νανοσωματίδια (MNPs) φερρίτη του μαγγανίου, και μελετήθηκαν οι δυνατότητές τους στην ελεγχόμενη και στοχευμένη χορήγηση.

description: The early diagnosis and treatment of cancer remains a huge challenge for scientists, as it is one of the most leading causes of death worldwide. Several types of treatment have been developed so far, with surgical resection, radiotherapy and chemotherapy being the most important. The subject of the present study offers an alternative approach to standard chemotherapy. More specifically, it takes advantage of the new perspectives provided by nanotechnology, which aims at developing innovative formulations using lower concentrations of anticancer drugs (thus reducing the serious side-effects of chemotherapy), while at the same time increasing bioavailability. For this, core-shell polymeric nano-carriers were prepared, and the anticancer drug paclitaxel as well as manganese ferrite magnetic nanoparticles (MNPs) were entrapped inside them. Their potential as controlled and targeted drug delivery systems was also studied. The polymer matrix was formed using two fully biodegradable and biocompatible copolymers, which were successfully synthesized for the first time in a previous work of our lab.

description: As a ramification of a motivational discussion for previous joint work, in which equations of motion for the finite spectral action of the Standard Model were derived, we provide a new analysis of the results of the calculations herein, switching from the perspective of Spectral triple to that of Fredholm module and thus from the analogy with Riemannian geometry to the pre-metrical structure of the Noncommutative geometry. Using a suggested Noncommutative version of Morse theory together with algebraic $K$-theory to analyse the vacuum solutions, the first two summands of the algebra for the finite triple of the Standard Model arise up to Morita equivalence. We also demonstrate a new vacuum solution whose features are compatible with the physical mass matrix.

description: The demand for museums’ openness in conjunction with the political, economic and social developments of the last decade reveals the importance of re-designing their communication policy. This paper study combines the need for communication policy with the fulfillment of the mission-vision of the museum. Focusing in these aims, the paper examines the communication policy and analyzes the existing means in the museum's interior and exterior environment. In this context, this paper study focuses on the case of Thessaloniki Cinema Museum examining the communication policy and exploring the needs it satisfies and mainly if the TCM satisfies them. The main aim is via the study of existing communication structure of the Museum, on the one hand to identify and evaluate its shortcomings and on the other hand by evaluating the upcoming results to make suggestions for optimizing the communication possibilities for Thessaloniki Cinema Museum.

description: We present the first results from the X-SHOOTER Lyman-$α$ survey at $z=2$ (XLS-$z2$). XLS-$z2$ is a deep spectroscopic survey of 35 Lyman-$α$ emitters (LAEs) utilising $\approx90$ hours of exposure time with VLT/X-SHOOTER and covers rest-frame Ly$α$ to H$α$ emission with R$\approx4000$. We present the sample selection, the observations and the data reduction. Systemic redshifts are measured from rest-frame optical lines for 33/35 sources. In the stacked spectrum, our LAEs are characterised by an interstellar medium with little dust, a low metallicity and a high ionisation state. The ionising sources are young hot stars that power strong emission-lines in the optical and high ionisation lines in the UV. The LAEs exhibit clumpy UV morphologies and have outflowing kinematics with blue-shifted SiII absorption, a broad [OIII] component and a red-skewed Ly$α$ line. Typically 30 % of the Ly$α$ photons escape, of which one quarter on the blue side of the systemic velocity. A fraction of Ly$α$ photons escapes directly at the systemic suggesting clear channels enabling a $\approx10$ % escape of ionising photons, consistent with an inference based on MgII. A combination of a low effective HI column density, a low dust content and young star-burst determine whether a star forming galaxy is observed as a LAE. The first is possibly related to outflows and/or a fortunate viewing angle, while we find that the latter two in LAEs are typical for their stellar mass of 10$^9$ M$_{\odot}$.

Alterations in cardiac responses to adrenergic agonists and in circulating thyroid hormones in alloxan induced diabetic rats
Creators: name: Bi, Yi Jia
Publisher: name: University of British Columbia
Year: 2009

description: The effects of adrenergic agonists in the heart were investigated in isolated cardiac tissues and in the whole heart in 8 week diabetic and age-matched control rats by measuring contractile force following administration of PE in presence of timolol, or ISO. Plasma thyroid hormones as well as insulin, glucose and triglyceride was measured. The contractile force of the isolated cardiac tissues was measured in tissue baths under physiological conditions and results expressed by construction of concentration response curves to adrenoceptors agonists, 10⁻⁹ to 10⁻⁴ M for ISO and 10⁻⁷ to 10⁻³ M for PE. The contractile force of the whole heart was measured as left ventricular systolic pressure, without pharmacological intervention and following administration of 10⁻⁶ M PE or 10⁻⁵ M ISO in the perfusate. The hearts were clamp-frozen at 0, 15 and 30 seconds, and 1, 4 minutes following adrenoceptor agonists for measurement of cAMP levels. Cardiac cAMP was measured in the frozen ventricles by employing Amersham commercial SPA kit while protein was measured by using Bio-Rad Dye method. The tissue content of cAMP was expressed as pmol cAMP/mg protein. It was found that the contractile response to PE was increased whereas that to ISO was decreased significantly in diabetic papillary muscle but not the left atria from the same group of animals. The chronotropic effect of PE was increased and that of ISO was decreased significantly in diabetic right atria. The contractile force of the whole heart preparation was increased in diabetic hearts following both adrenoceptor agonists and the increased positive inotropic effect of ISO was accompanied by an increase in cAMP levels. In all of the diabetic animals, the thyroid hormone levels were significantly lower than those of the controls. These findings confirmed that the cardiac alterations and the low thyroid state in ALX-induced diabetic rats are similar to those that occur in STZ-induced diabetic rats although further studies would be needed to reveal the interrelation between the diabetesassociated low thyroid state and diabetic cardiomyopathy.
Why exercise builds muscles: Titin mechanosensing controls skeletal muscle growth under load

description: Muscles sense internally generated and externally applied forces, responding to these in a coordinated hierarchical manner at different time scales. The center of the basic unit of the muscle, the sarcomeric M-band, is perfectly placed to sense the different types of load to which the muscle is subjected. In particular, the kinase domain (TK) of titin located at the M-band is a known candidate for mechanical signaling. Here, we develop the quantitative mathematical model that describes the kinetics of TK-based mechanosensitive signaling, and predicts trophic changes in response to exercise and rehabilitation regimes. First, we build the kinetic model for TK conformational changes under force: opening, phosphorylation, signaling and autoinhibition. We find that TK opens as a metastable mechanosensitive switch, which naturally produces a much greater signal after high-load resistance exercise than an equally energetically costly endurance effort. Next, in order for the model to be stable, give coherent predictions, in particular the lag following the onset of an exercise regime, we have to account for the associated kinetics of phosphate (carried by ATP), and for the non-linear dependence of protein synthesis rates on muscle fibre size. We suggest that the latter effect may occur via the steric inhibition of ribosome diffusion through the sieve-like myofilament lattice. The full model yields a steady-state solution (homeostasis) for muscle cross-sectional area and tension, and a quantitatively plausible hypertrophic response to training as well as atrophy following an extended reduction in tension.

description: In this paper, we propose a generalization for the class of laura algebras, which we call almost laura. We show that this new class of algebras retains most of the essential features of laura algebras, especially concerning the important role played by the non-semiregular components in their Auslander-Reiten quivers. Also, we study more intensively the left supported almost laura algebras, showing that these are characterized by the presence of a generalized standard, convex and faithful component. Finally, we prove that almost laura algebras behave well with respect to full subcategories, split-by-nilpotent extensions and skew group algebras.

description: We perform a Koopman spectral analysis of elementary cellular automata (ECA). By lifting the system dynamics using a one-hot representation of the system state, we derive a matrix representation of the Koopman operator as a transpose of the adjacency matrix of the state-transition network. The Koopman eigenvalues are either zero or on the unit circle in the complex plane, and the associated Koopman eigenfunctions can be explicitly constructed. From the Koopman eigenvalues, we can judge the reversibility, determine the number of connected components in the state-transition network, evaluate the periods of asymptotic orbits, and derive the conserved quantities for each system. We numerically calculate the Koopman eigenvalues of all rules of ECA on a one-dimensional lattice of 13 cells with periodic boundary conditions. It is shown that the spectral properties of the Koopman operator reflect Wolfram's classification of ECA.

description: We present low temperature transport measurements in one dimensional Josephson junctions rhombi chains. We have measured the current phase relation of a chain of 8 rhombi. The junctions are either in the classical phase regime with the Josephson energy much larger than the charging energy, $E_{J}\gg E_{C}$, or in the quantum phase regime where $E_{J}/E_{C}\approx 2$. In the strong Josephson coupling regime ($E_{J}\gg E_{C} \gg k_{B}T$) we observe a sawtooth-like supercurrent as a function of the phase difference over the chain. The period of the supercurrent oscillations changes abruptly from one flux quantum $Φ_{0}$ to half the flux quantum $Φ_{0}/2$ as the rhombi are tuned in the vicinity of full frustration. The main observed features can be understood from the complex energy ground state of the chain. For $E_{J}/E_{C}\approx 2$ we do observe a dramatic suppression and rounding of the switching current dependence which we found to be consistent with the model developed by Matveev et al.(Phys. Rev. Lett. {\bf 89}, 096802(2002)) for long Josephson junctions chains.

description: The boson star filled with two interacting scalar fields is investigated. The scalar fields can be considered as a gauge condensate formed by SU(3) gauge field quantized in a non-perturbative manner. The corresponding solution is regular everywhere, has a finite energy and can be considered as a quantum SU(3) version of the Bartnik - McKinnon particle-like solution.
