description: Roles of many genes in a typical genome are still unknown or only partially explored. Experiments that determine the gene function are expensive and time-consuming, necessitating development of novel computational methods to predict gene functions by using machine learning and knowledge discovery techniques. It is known from comparative genomics that certain functionally interacting groups of genes reside in conserved neighbourhoods in phylogenetically distant bacterial genomes. In this work we present a novel feature construction method which uses the functional composition of a gene’s neighbourhood on the chromosome as features for inferring the gene’s functions. We integrate data across approx. 1000 bacterial and archaeal genomes using COG gene families; each COG is then described by the average frequency of gene functions in its close neighbourhood across many genomes.

description: Taking the dominant couplings in the standard model to be the quartic scalar coupling, the Yukawa coupling of the top quark, and the SU(3) gauge coupling, we consider their associated running couplings to one loop order. Despite the non-linear nature of the differential equations governing these functions, we show that they can be solved exactly. The nature of these solutions is discussed and their singularity structure is examined. It is shown that for a sufficiently small Higgs mass, the quartic scalar coupling decreases with increasing energy scale and becomes negative, indicative of vacuum instability. This behavior changes for a Higgs mass greater than 168 GeV, beyond which this couplant increases with increasing energy scales and becomes singular prior to the ultraviolet (UV) pole of the Yukawa coupling. Upper and lower bounds on the Higgs mass corresponding to new physics at the TeV scale are obtained and compare favourably with the numerical results of the one-loop and two-loop analyses with inclusion of electroweak couplings.

description: Telomere length dynamics in lung adenocarcinomas has been extensively studied. However, details on how mean telomere length (MTL) is associated with activity changes in signaling, metabolic and regulatory pathways is scarce. We have studied the connection of MTL with biomolecular pathway deregulations in 26 lung adenocarcinoma cell lines.
MTL was computed from whole genome sequencing data with an in-house program Computel. The RNA-seq data was analyzed with an Pathway Signal Flow algorithm for assessing the activity profiles of 168 KEGG pathways in the studied samples. We performed partial correlation analysis of MTL with pathway signal flow values. The top three pathways positively correlated with telomere length (local FDR p value < 0.05) were Cytokine-cytokine receptor interaction, Purine metabolism and Glycolysis/Gluconeogenesis pathways (Spearman correlation coefficients 0.46, 0.42 and 0.4). The pathways identified in this study have previously been strongly implicated in lung adenocarcinomas. The cytokine-cytokine receptor interaction pathway has been shown altered both on the levels of expression and genetic variations. Additionally, purine metabolism and glycolysis/gluconeogenesis acceleration was shown to be characteristic of poorly differentiated tumors, such as adenocarcinomas. Moreover, telomerase targeting of tumor cells has been shown to have strong effect on activation of the glycolytic pathway.
In conclusion, this study for the first time demonstrated the possible association of mean telomere length with activation of metabolic and signaling pathways involved in growth and proliferation of lung adenocarcinoma cells.

description: We employ N-body, smoothed particle hydrodynamical simulations, including detailed treatment of chemical enrichment, to follow a gas-rich merger which results in a galaxy with disk morphology. We trace the kinematic, structural and chemical properties of stars formed before, during, and after the merger. We show that such a merger produces two exponential disk components, with the older, hotter component having a scale-length 20% larger than the later-forming, cold disk. Rapid star formation during the merger quickly enriches the protogalactic gas reservoir, resulting in high metallicities of the forming stars. These stars form from gas largely polluted by Type II supernovae, which form rapidly in the merger-induced starburst. After the merger, a thin disk forms from gas which has had time to be polluted by Type Ia supernovae. Abundance trends are plotted, and we examine the proposal that increased star formation during gas-rich mergers may explain the high alpha-to-iron abundance ratios which exist in the relatively high-metallicity thick disk component of the Milky Way.

description: We perform collisionless N-body simulations of 1:1 galaxy mergers, using models which include a galaxy halo, disc and bulge, focusing on the behaviour of the halo component. The galaxy models are constructed without recourse to a Maxwellian approximation. We investigate the effect of varying the galaxies' orientation, their mutual orbit, and the initial velocity anisotropy or cusp strength of the haloes upon the remnant halo density profiles and shape, as well as on the kinematics. We observe that the halo density profile (determined as a spherical average, an approximation we find appropriate) is exceptionally robust in mergers, and that the velocity anisotropy of our remnant haloes is nearly independent of the orbits or initial anisotropy of the haloes. The remnants follow the halo anisotropy - local density slope (β-γ) relation suggested by Hansen & Moore (2006} in the inner parts of the halo, but βis systematically lower than this relation predicts in the outer parts. Remnant halo axis ratios are strongly dependent on the initial parameters of the haloes and on their orbits. We also find that the remnant haloes are significantly less spherical than those described in studies of simulations which include gas cooling.

Clusters die hard: Time-correlated excitation in the Hamiltonian Mean Field model

description: The Hamiltonian Mean Field (HMF) model has a low-energy phase where $N$ particles are trapped inside a cluster. Here, we investigate some properties of the trapping/untrapping mechanism of a single particle into/outside the cluster. Since the single particle dynamics of the HMF model resembles the one of a simple pendulum, each particle can be identified as a high-energy particle (HEP) or a low-energy particle (LEP), depending on whether its energy is above or below the separatrix energy. We then define the trapping ratio as the ratio of the number of LEP to the total number of particles and the ``fully-clustered'' and ``excited'' dynamical states as having either no HEP or at least one HEP. We analytically compute the phase-space average of the trapping ratio by using the Boltzmann-Gibbs stable stationary solution of the Vlasov equation associated with the $N \to \infty$ limit of the HMF model. The same quantity, obtained numerically as a time average, is shown to be in very good agreement with the analytical calculation. Another important feature of the dynamical behavior of the system is that the dynamical state changes transitionally: the ``fully-clustered'' and ``excited'' states appear in turn. We find that the distribution of the lifetime of the ``fully-clustered'' state obeys a power law. This means that clusters die hard, and that the excitation of a particle from the cluster is not a Poisson process and might be controlled by some type of collective motion with long memory. Such behavior should not be specific of the HMF model and appear also in systems where {\it itinerancy} among different ``quasi-stationary'' states has been observed. It is also possible that it could mimick the behavior of transient motion in molecular clusters or some observed deterministic features of chemical reactions.

description: The physics of a Tonks-Giradeau Gas in the presence of a local potential is studied. In order to evaluate the single particle density matrix (SPDM) of the many-body ground state, the Wiger-Jordan transformation is used. The eigenvector with the largest eigenvalue of the SPDM corresponds to the "Bose-Einstein Condensate"(BEC) State. We find that the "BEC" state density at the positon of the local potential decreases, as expected, in the case of a repulsive potential. For an attractive potential, it decreases or increases depending on the strength of the potential. The superfluidity of this system is investigated both numerically and perturbatively. An experimental method for detecting the effect of an impurity in a Tonks-Giradueau gas is discussed.

description: The dephasing of coherent longitudinal optical (LO) phonons in ion-irradiated GaP has been investigated with a femtosecond pump-probe technique based on electro-optic sampling. The dephasing time of the coherent LO phonon is found to be dramatically prolonged by the introduction of a small amount of defects by means of Ga-ion irradiation. The maximum dephasing time observed at room temperature is 9.1 ps at a Ga$^{+}$ ion dose of 10$^{13}$/cm$^{2}$, which is significantly longer than the value of 8.3 ps for GaP before ion irradiation. The longer dephasing time is explained in terms of the suppression of electron-LO-phonon scattering by the presence of defect-induced deep levels.

description: Understanding the dynamics around rotating black holes is imperative to the success of the future gravitational wave observatories. Although integrable in principle, test particle orbits in the Kerr spacetime can also be elaborate, and while they have been studied extensively, classifying their general properties has been a challenge. This is the first in a series of papers that adopts a dynamical systems approach to the study of Kerr orbits, beginning with equatorial orbits. We define a taxonomy of orbits that hinges on a correspondence between periodic orbits and rational numbers. The taxonomy defines the entire dynamics, including aperiodic motion, since every orbit is in or near the periodic set. A remarkable implication of this periodic orbit taxonomy is that the simple precessing ellipse familiar from planetary orbits is not allowed in the strong-field regime. Instead, eccentric orbits trace out precessions of multi-leaf clovers in the final stages of inspiral. Furthermore, for any black hole, there is some point in the strong-field regime past which zoom-whirl behavior becomes unavoidable. Finally, we sketch the potential application of the taxonomy to problems of astrophysical interest, in particular its utility for computationally intensive gravitational wave calculations.

description: We study a sample of 48127 galaxies selected from the SDSS MPA-JHU catalogue, with $\log M_{\star}/M_{\odot} = 10.73 - 11.03$ and $z<0.1$. Local galaxies in this stellar mass range have been shown to have systematically shorter assembly times within their inner regions ($<0.5~R_{50}$) when compared to that of the galaxy as a whole, contrary to lower or higher mass galaxies which show consistent assembly times at all radii. Hence, we refer to these galaxies as Inside-Out Assembled Galaxy (IOAG) candidates. We find that the majority of IOAG candidates with well-detected emission lines are classified as either AGN (40%) or composite (40%) in the BPT diagram. We also find that the majority of our sources are located below the main sequence of star formation, and within the green valley or red sequence. Most BPT-classified star-forming IOAG candidates have spiral morphologies and are in the main sequence, whereas Seyfert 2 and composites have mostly spiral morphologies but quiescent star formation rates (SFRs). We argue that a high fraction of IOAG candidates seem to be in the process of quenching, moving from the blue cloud to the red sequence. Those classified as AGN have systematically lower SFRs than star-forming galaxies suggesting that AGN activity may be related to this quenching. However, the spiral morphology of these galaxies remains in place, suggesting that the central star-formation is suppressed before the morphological transformation occurs.

A microscopic nuclear equation of state derived in the Brueckner-Hartree-Fock approach is used together with compatible neutron and proton pairing gaps. We then study the effect of modifying the gaps on the final deduced neutron star mass distributions. We find that a consistent description of all current cooling data can be achieved and a reasonable neutron star mass distribution can be predicted employing the (slightly reduced by about 40\%) proton 1S0 Bardeen-Cooper-Schrieffer (BCS) gaps and no neutron 3P2 pairing.

We argue that generalised geometry enables us to treat these non-geometric compactifications using a supergravity analysis in a way very similar to geometric compactifications. We find supersymmetric Minkowski vacua with all the moduli stabilised at weak string coupling and all the tadpole conditions satisfied. Generically the value of the moduli fields in the vacuum is parametrically controlled and can be taken to arbitrarily large values.

Αφού μελετήθηκε ο ηλεκτρονικός row decoder ξεκινήσαμε την υλοποίηση του οπτικού row decoder βήμα βήμα. Πρώτα υλοποιήθηκε η οπτική πύλη ΝΟΤ και στη συνέχεια η οπτική πύλη AND. Αφού μελετήθηκαν τα θετικά αποτελέσματα των οπτικών πυλών προχωρήσαμε στον κατάλληλο συνδυασμό αυτών με στόχο την υλοποίηση του row decoder. Ανάλογα με τα σήματα εισόδου που εισέρχονται στον row decoder κάθε δορά ενεργοποιείται στην έξοδό του και μία διαφορετική γραμμή αποθήκευσης της συστοιχίας κελιών μνήμης. Η επιλογή της στήλης αποθήκευσης γίνεται από τον column decoder. Η υλοποίηση του column decoder είναι πολύ απλή και υλοποιείται με έναν WDM αποπολυπλέκτη.
description: In this diploma thesis is presented the problem of «Memory Wall» and the need to implement optical RAM memory. The aim of this thesis is to explore and identify the factors that lead to the design of optical memories. We must find a way to implement the individual pieces of logic gates. Some of the key regional circuits of memory are encoders and decoders. The main objective is to study and create a purely optical decoder and specifically, the row decoder. Having studied the electronic row decoder first, we continued to the implementation of the optical row decoder. We implemented the optical NOT gate and then the optical AND gate. Having studied the positive effects of optical gates, we proceeded to the appropriate combination of these in order to implement the row decoder. Depending on the input signals entering in the row decoder, only one output is activated and consequently a different line of storage memory cell array. The choice of column storage is done by the column decoder. The implementation of the column decoder is very simple and involves a WDM demultiplexer.

description: We develop a model for the weak pion production off the nucleon, which besides the Delta pole mechanism (weak excitation of the $Δ(1232)$ resonance and its subsequent decay into $Nπ$), includes also some background terms required by chiral symmetry. We re-fit the $C_5^A(q^2)$ form factor to the flux averaged $ν_μp \to μ^-pπ^+$ ANL $q^2-$differential cross section data, finding a substantially smaller contribution of the Delta pole mechanism than traditionally assumed in the literature. Within this scheme, we calculate several differential and integrated cross sections, including pion angular distributions, induced by neutrinos and antineutrinos and driven both by charged and neutral currents. In all cases we find that the background terms produce quite significant effects and that they lead to an overall improved description of the data, as compared to the case where only the Delta pole mechanism is considered. We also show that the interference between the Delta pole and the background terms produces parity-violating contributions to the pion angular differential cross section, which are intimately linked to $T-$odd correlations in the contraction between the leptonic and hadronic tensors. However, these latter correlations do not imply a genuine violation of time reversal invariance because of the existence of strong final state interaction effects.

Modeling Curtailment in Germany: How Spatial Resolution Impacts Line Congestion

description: This paper investigates the effects of network constraints in energy system models at transmission level on renewable energy generation and curtailment as the network is being spatially aggregated. We seek to reproduce historically measured curtailment in Germany for the years 2013-2018 using an open model of the transmission system, PyPSA-Eur. Our simulations include spatial and temporal considerations, including congestion per line as well as curtailment per control zone and quarter. Results indicate that curtailment at high network resolution is significantly overestimated due to inaccurate allocation of electricity demand and renewable capacities to overloaded sites. However, high congestion rates of the transmission network decrease as the network is clustered to a smaller number of nodes, thus reducing curtailment. A measure to capture errors in the assignment of electricity demand and power plants is defined and hints towards a preferable spatial resolution. Thus, we are able to balance the effects of accurate node assignment and network congestion revealing that a reduced model can capture curtailment from recent historical data. This shows that it is possible to reduce the network to improve computation times and capture the most important effects of network constraints on variable renewable energy feed-in at the same time.

description: Μελετώντας κανείς την σκέψη των αρχαίων Ελλήνων έρχεται σε επαφή με τις παραθέσεις απόψεων 2.500 ετών πριν και δε μπορεί παρά να εντυπωσιαστεί από το μοναδικό μεγαλείο του πνεύματός τους. Ένα από αυτά τα θέματα, το οποίο και πραγματεύεται η παρούσα μελέτη, είναι η παιδεία. Η εκπαίδευση πρέπει να αντλεί την πραγματικότητά και τον αληθινό σκοπό της από τη σύνδεσή της με τη ζωή. Η τέχνη της εκπαίδευσης έχει δημιουργηθεί για να βοηθήσει τον άνθρωπο να συστηματοποιήσει και να διευρύνει την εμπειρία του, να κατανοήσει τον εαυτό του και να μπορεί να συνεργάζεται δημιουργικά με τους συνανθρώπους του προς έναν κοινό σκοπό, τη βελτίωση της ζωής τους, τόσο σε πρακτικό, όσο και σε ηθικό επίπεδο. Σκοπός της μεταπτυχιακής αυτής εργασίας είναι να αναλυθούν το περιεχόμενο και οι σκοποί της παιδείας, όπως προκύπτουν από τη συζήτηση για τη Δικαιοσύνη στον Πλάτωνα και από την προσπάθεια σύνδεσης της Ηθικής με την Πολιτική Επιστήμη στον Αριστοτέλη. Στην πρώτη ενότητα, παραθέτονται εν συντομία στοιχεία του βίου και του έργου του Πλάτωνα και στη συνέχεια, οι απόψεις του για την παιδεία, όπως εκφράστηκαν κυρίως στα δύο μεγάλα έργα του, την «Πολιτεία» και τους «Νόμους». Η δεύτερη ενότητα ξεκινά με την παράθεση στοιχείων από τη ζωή και το συγγραφικό έργο του Αριστοτέλη και συνεχίζεται με την εξέταση των προτάσεών του για το θέμα και το τέλος της παιδείας. Έργα αναφοράς αποτελούν, κυρίως, τα «Ηθικά Νικομάχεια» και τα «Πολιτικά» του.
description: Studying the ancient Greek thought gives us an excellent chance to dive into their expressed opinions which date back 2500 years ago and the only we can only feel absolutely impressed by their high intelligence and splendor. Education, one of these ancient Greek thoughts, is the main subject of the current (paper). True education should derive its existence from the reality and its first purpose should be no other than its connection to real life. The art of educating has been created so as to help man systematize and widen his experience, understand himself and creatively cooperate on a common goal with his fellow men. This goal is to improve their lives, practically and ethically, at the same time. This paper tries to analyze the content and the main purposes of what is called Education, as it is revealed through discussion about Justice in Plato and along with the effort to connect Ethics to Political Science in Aristotle. A brief overview of Plato’s life and works covers the first section. Afterwards, we deal with his thoughts on education, as they have been developed in his great works, “The Republic” and “Laws”. The second section begins with details about Aristotle’s life and his writings and it continues with a thorough look at his views on the meaning and purpose of Education. There is a main reference to his works “Nicomachean Ethics” and “Politics”.

description: Στις μέρες μας, η τεχνολογία οπτικής μεταγωγής ριπής (OBS) έχει αποδειχθεί ένα αποτελεσματικό μοντέλο για την υποστήριξη IP κίνησης πάνω από WDM δίκτυα. Η ανάπτυξη ποικίλων εφαρμογών που μεταφέρουν φωνή, δεδομένα, βίντεο και πολυμέσα, έχει καταστήσει αναγκαία την παροχή ποιότητας υπηρεσίας (Quality of Service) πάνω από OBS δίκτυα. Με το πέρασμα των χρόνων και παρά την εξέλιξη της τεχνολογίας μετατροπής μήκους κύματος παρατηρείται μία πιο περιορισμένη ανάπτυξη αυτών των μετατροπέων στα δίκτυα OBS. Αντικείμενο της παρούσας μελέτης – εργασίας είναι η περιγραφή, μοντελοποίηση, προσομοίωση και μελέτη της λειτουργίας ενός δικτύου οπτικής μεταγωγής ριπής, με τη βοήθεια του εργαλείου προσομοίωσης OMNeT++. Προτείνεται μια προσέγγιση για τον έλεγχο παθητικών οπτικών αστέρων με πολυπλεξία διαίρεσης μήκους κύματος, η οποία περιλαμβάνει ουρά αφίξεων για καθυστερημένη παραλαβή. Αυτή η λύση φέρνει τα δίκτυα οπτικού αστέρα ένα βήμα πιο κοντά σε μία πλήρως οπτική πραγματικότητα, παρέχοντας υψηλή απόδοση, χαμηλή καθυστέρηση, μικρές απαιτήσεις μνήμης και αξιοπιστία κάτα από όλες τις συνθήκες κίνησης.
description: Nowadays, the optical burst switching technology (OBS) has proved to be an efficient paradigm for supporting IP traffic over WDM networks. The growth of a variety of applications which transmit voice, data, video and multimedia, has necessitated the need to provide Quality of Service (QoS) over OBS networks. Over the years and despite the development of wavelength conversion technology, it is likely to dictate a more limited deployment of wavelength converters in optical burst switching networks (OBS). Purpose of this study is the description, modeling, simulation and study of the operation of OBS, with the network simulator OMNeT++. This paper proposes an approach to controlling wavelength-division-multiplexing passive optical stars, consisting in queuing arrivals for delayed reception. This solution brings optical star networks a step closer to all-optical realization, providing high throughput, low delay, small buffer requirements, and robustness under all traffic conditions.
