Τεχνολογίες της Πληροφορίας και Επικοινωνίας(ΤΠΕ)
Εργαλειακός, Οικο-κοινωνικός, κριτικός λόγος

description: Στην παρούσα εργασία παρουσιάζεται η ανάδειξη των μοντέλων λόγου που έξι έφηβοι υιοθετούν ως προς τη χρήση των νέων τεχνολογιών και ως προς το μελλοντικό τους προσανατολισμό. Στην συνέχεια ακολουθεί η κατηγοριοποίησή των πρώτων βάσει των λόγων (discourses) που υιοθετούνται, όπως προκύπτει από τη διάκριση του Κουτσογιάννης (εργαλειακός, οικο-κοινωνικός, κριτικός) (2009), ενώ για τα μοντέλα Λόγου σχετικά με το μελλοντικό προσανατολισμό υιοθετείται η διάκριση της Mitsikopoulou (2007) (λόγος ανάπτυξης και προόδου, κοσμοπολίτικος λόγος). Τέλος ακολουθεί η συσχέτιση των λόγων που υιοθετούνται από κάθε έφηβο με την κοινωνικοοικονομική κατάσταση της οικογένειάς του. Από την ανάλυση προκύπτει ότι οι μαθητές από τα προνομιούχα κοινωνικά στρώματα υιοθετούν στις σχολικές κυρίως πρακτικές γραμματισμού μοντέλα λόγου που ανήκουν περισσότερο στην οικο-κοινωνική και κριτική οπτική για τη χρήση των ΤΠΕ και την κοσμοπολιτική οπτική για τον μελλοντικό τους προσανατολισμό. Αντίθετα, οι μαθητές που προέρχονται από μη προνομιούχα κοινωνικά στρώματα αναπτύσσουν εργαλειακή σχέση ως προς τη χρήση των ΤΠΕ, ενώ για τα μελλοντικά τους σχέδια ακολουθούν τη λογική της προόδου και της ανάπτυξης. Ανάλογη τέλος, είναι η στάση του οικογενειακού τους περιβάλλοντος ως προς την υιοθέτηση των αντίστοιχων μοντέλων λόγου.
description: In the present study, we described the appointment of the discourse models which six teenagers adopt regarding the use of new technology and their future vocational guidance. Consequently follows the classification of the former, based on the adopted discourses, ensuing by the differentiation of Koutsogianis (instrumentalist, eco-social, critical) (2009), when for the discourse models regarding the future vocational guidance, is adopted the differentiation of Mitsikopoulou(2007)(progress and development discourse, cosmopolitan discourse). Finally follows the correlation of the adopted discourses from every teenager regarding the socioeconomic condition of his family. From the analysis arises that students from preferential social rank, adopt, mainly at the school literacy practices, discourse models more inhering at the eco –social and critical discourse for the use of ICT (information and communication technologies) and the cosmopolitan discourse for the future vocational guidance. On the contrary, students from non-preferential social rank develop instrumental relation regarding the use of ICT (information and communication technologies), whereas for their future plans adopt the progress and development discourse. Finally the attitude of their family environment is relative, regarding the adoption of the equivalent discourse models.

description: We consider the noncommutative space-times with Lie-algebraic noncommutativity (e.g. $κ$-deformed Minkowski space). In the framework with classical fields we extend the $\star$-product in order to represent the noncommutative translations in terms of commutative ones. We show the translational invariance of noncommutative bilinear action with local product of noncommutative fields. The quadratic noncommutativity is also briefly discussed.

description: We present a synthetic spectral analysis of IUE archival and FUSE FUV spectra of the peculiar dwarf nova WW Ceti. During the quiescence of WW Ceti, a white dwarf with Twd=26,000K can account for the FUV flux and yields the proper distance. However, the best agreement with the observations is provided by a two-temperature white dwarf model with a cooler white dwarf at Twd=25,000K providing 75% of the FUV flux and a hotter region (accretion belt or optically thick disk ring) with T=40,000K contributing 25% of the flux for the proper distance. We find from the FUSE spectrum that the white dwarf is rotating with a projected rotational velocity V sin{i} = 600 km/s. Our temperature results provide an additional data point in the distribution of Twd versus orbital period above the CV period gap where few Twds are available.

description: Present day chiral nucleon-nucleon potentials up to N3LO and three nucleon forces at N2LO are used to analyze nucleon-deuteron radiative capture at deuteron lab energies below E_d= 100 MeV. The differential cross section and the deuteron analyzing powers A_y(d) and A_{yy} are presented and compared to data. The theoretical predictions are obtained in the momentum-space Faddeev approach using the nuclear electromagnetic current operator with exchange currents introduced via the Siegert theorem. The chiral forces provide the same quality of data description as a combination of the two-nucleon AV18 and the three-nucleon Urbana IX interactions. However, the different parametrizations of the chiral potentials lead to broad bands of predictions.

Μέσα από μία εκπαιδευτική παρέμβαση σε παιδιά έκτης δημοτικού ελέγχονται οι δυνατότητες και η αποτελεσματικότητα του ΘτΚ. Επιπλέον, διερευνάται το κατά πόσο η μέθοδος αυτή, ως εφαρμογή της δραματικής τέχνης, μπορεί να αποτελέσει ένα εργαλείο που προκαλεί και τελικά επιφέρει αύξηση της ενσυναίσθησης αναφορικά με το περιβαλλοντικό ζήτημα το οποίο θέτει, καθώς και το κατά πόσο, ως κατεξοχήν μέθοδος ενδυνάμωσης, έχει ανάλογα αποτελέσματα ανάπτυξης δράσης και στους/ στις μαθητές/ τριες. Ουσιαστικά αυτή η έρευνα αποτελεί τον πρώτο κύκλο μιας έρευνας δράσης, πάνω στα ευρήματα του οποίου θα σχεδιαστεί ο δεύτερος κύκλος. Η αξιολόγηση αυτού του πρώτου κύκλου εμφάνισε ξεκάθαρη ανάπτυξη της ενσυναίσθησης και ενδείξεις ενδυνάμωσης. Επιπλέον, παρατηρήθηκε σίγουρη μετατόπιση του σημείου ελέγχου από εξωτερικό σε εσωτερικό, όσον αφορά στη πρόθεση για δράση. Τέλος, αξίζει να σημειωθεί ότι όλα τα παραπάνω ευρήματα αφορούν κυρίως τα παιδιά που μπήκαν στο ρόλο του καταπιεζόμενου και σε πολύ λιγότερες ατομικές περιπτώσεις τα παιδιά που δε μπήκαν σε ρόλο, αλλά συμμετείχαν στις υπόλοιπες δραστηριότητες της παρέμβασης.
description: The present study examines the oppression of animals by humans, as a subject that is consistent with environmental education, by applying activities from Theatre of the Oppressed (ToO) of Augusto Boal. The ability and the effectiveness of ToO are also examined through an intervention that was carried out with students in the last class of primary school. Furthermore, the capacity of the method, as an application of drama, is explored examining whether it can comprise a tool that can induce empathy, as well as empower the students, taking into account that ToO is primarily considered as an empowerment method. This study is actually a first cycle of an action research and on its results the second cycle would be designed. The evaluation of this first cycle showed a clear development of empathy and indications of empowerment. In addition, a shift in the locus of control was observed, from external to internal, as far as the intention to act is concerned. It is worthwhile mentioning that these results count mostly for the students that got inside the role of the oppressed and only in a few individual cases for the students that did not become protagonists, but participated in the other activities of the intervention.

description: We provide a quantitative analysis of the phenomenon of crowding of near-extreme events by computing exactly the density of states (DOS) near the maximum of a set of independent and identically distributed random variables. We show that the mean DOS converges to three different limiting forms depending on whether the tail of the distribution of the random variables decays slower than, faster than, or as a pure exponential function. We argue that some of these results would remain valid even for certain {\em correlated} cases and verify it for power-law correlated stationary Gaussian sequences. Satisfactory agreement is found between the near-maximum crowding in the summer temperature reconstruction data of western Siberia and the theoretical prediction.

description: We study the problem of inferring communication structures that can solve cooperative multi-agent planning problems while minimizing the amount of communication. We quantify the amount of communication as the maximum degree of the communication graph; this metric captures settings where agents have limited bandwidth. Minimizing communication is challenging due to the combinatorial nature of both the decision space and the objective; for instance, we cannot solve this problem by training neural networks using gradient descent. We propose a novel algorithm that synthesizes a control policy that combines a programmatic communication policy used to generate the communication graph with a transformer policy network used to choose actions. Our algorithm first trains the transformer policy, which implicitly generates a "soft" communication graph; then, it synthesizes a programmatic communication policy that "hardens" this graph, forming a neurosymbolic transformer. Our experiments demonstrate how our approach can synthesize policies that generate low-degree communication graphs while maintaining near-optimal performance.

description: Peritonsillar abscess (PTA) is a common deep neck infection traditionally managed with conservative measures. Quinsy Tonsillectomy (QT) is recognized as a definitive treatment but remains variably utilized. We aimed to investigate PTA management strategies and attitudes toward QT among otolaryngologists. An anonymous questionnaire was distributed to members of the local national Society of Otolaryngology, evaluating treatment strategies based on patient characteristics and clinical scenario. A total of 108 otolaryngologists responded (response rate: 30.8%). Participants preferred to treat PTA patients as inpatients (89%) and predominantly offered incision and drainage (I&D) as the first (90.7%) and subsequent (98.1%) treatment plan. QT was favored as a primary treatment only in 1.9% of responders. QT adoption increased with multiple I&D failures, reaching 95.3% after four attempts. In patients with recurrent PTA or tonsillitis, 84.2% preferred I&D follows by interval elective tonsillectomy, while 15% considered QT. The most common reason (72.2%) to avoid QT was the perception of a high perioperative risk. I&D was favored for initial PTA treatment. QT is considered after multiple failed I&D attempts, and its use is limited as a primary treatment, mainly due to concerns regarding perioperative risk.

description: An efficient O(N) cluster Monte Carlo method for Ising models with long-range interactions is presented. Our novel algorithm does not introduce any cutoff for interaction range and thus it strictly fulfills the detailed balance. The realized stochastic dynamics is equivalent to that of the conventional Swendsen-Wang algorithm, which requires O(N^2) operations per Monte Carlo sweep if applied to long-range interacting models. In addition, it is shown that the total energy and the specific heat can also be measured in O(N) time. We demonstrate the efficiency of our algorithm over the conventional method and the O(N log N) algorithm by Luijten and Bloete. We also apply our algorithm to the classical and quantum Ising chains with inverse-square ferromagnetic interactions, and confirm in a high accuracy that a Kosterlitz-Thouless phase transition, associated with a universal jump in the magnetization, occurs in both cases.

description: We introduce a program named KPROJ that unfolds the electronic and phononic band structure of materials modeled by supercells. The program is based on the $\textit{k}$-projection method, which projects the wavefunction of the supercell onto the ${\textbf{k}}$-points in the Brillouin zone of the artificial primitive cell. It allows for obtaining an effective "local" band structure by performing partial integration over the wavefunctions, e.g., the unfolded band structure with layer-projection for interfaces and the weighted band structure in the vacuum for slabs. The layer projection is accelerated by a scheme that combines the Fast Fourier Transform (FFT) and the inverse FFT algorithms. It is now interfaced with a few first-principles codes based on plane waves such as VASP, Quantum Espresso, and ABINIT. In addition, it also has interfaces with ABACUS, a first-principles simulation package based on numerical atomic basis sets, and PHONOPY, a program for phonon calculations.

description: This thesis aims to study Goppa codes and their application to the McEliece cryptosystem. We begin by presenting some basic elements of Algebra, Theory of Error Correcting Codes, and Cryptography. Next, we introduce cyclic codes and a specific type of cyclic codes, BCH codes. Using the fundamental equation of BCH codes, we construct Goppa codes. After studying the properties of Goppa codes and analyzing a decoding algorithm for them, we use them to examine the way the McEliece cryptosystem works, as well as its efficiency. We conclude with an analysis of some attacks against the McEliece cryptosystem.
Broadband Linear Polarization in the Region of the Open Star Cluster NGC 1817

description: Multi-band linear polarimetric observations of 125 stars in the region of the cluster NGC 1817 have been carried out intending to study properties of interstellar dust and grains in that direction. The polarization is found to be wavelength-dependent, being maximum in the V band with an average value of 0.95%. The foreground interstellar dust grains appear to be the main source of linear polarization of starlight toward the direction of NGC 1817. The average value of the position angle in the V band of 119.2 degree is found to be less than the direction of the Galactic parallel in the region, indicating that the dust grains in the direction are probably not yet relaxed. Spatial distribution of dust appears to be more diverse in the coronal region than the core region of the cluster. The maximum value of the degree of polarization is estimated to be 0.93% for members of the cluster using the Serkowski relation. The average value of wavelength corresponding to the maximum polarization of 0.54+/-0.02 micron indicates that the size distribution of dust grains in the line of sight is similar to that of the general interstellar medium. Several variable stars in the cluster were also observed for polarimetrically and pulsating variables appear to have a slightly lower value of polarization from other nonvariable member stars of the cluster. There are indications of the existence of dust layers existence in front of those clusters which are located close to galactic plane while for clusters located away from galactic plane no major dust layers are observed.

Prepararsi al matrimonio: per generare una famiglia cristiana

description: L’articolo si propone di offrire una riflessione sull’importanza degli itinerari catecumenali per la vita matrimoniale partendo dagli orientamenti pastorali proposti dal Dicastero per i laici, la famiglia e la vita. Rinnovare la preparazione al matrimonio delle prossime generazioni, considerando le nozze non un punto di arrivo, ma una tappa lungo un percorso sono questi gli obiettivi di questo documento presentato. Il testo mette in atto un suggerimento ripetutamente espresso da papa Francesco circa la necessità di un «nuovo catecumenato» che includa tutte le tappe del cammino sacramentale: i tempi della preparazione al matrimonio, della sua celebrazione e degli anni successivi. La presente riflessione vuole essere un modo semplice per stimolare un nuovo processo ecclesiale, pastorale e giuridico della preparazione al matrimonio, al fine di far comprendere alla coppia la differenza tra «prepararsi al giorno del matrimonio» e «prepararsi alla vita matrimoniale» con la persona con la quale deciderà di sposarsi. Il tutto passa necessariamente da un coinvolgimento della comunità cristiana (soggetto chiamato ad attuare gli itinerari) nelle sue varie articolazioni (pastorali, ecclesiali, giuridiche), da una formazione integrale dei fidanzati (destinatari degli itinerari) che mediante l'istruzione catechetica, la dimensione esperienziale, la partecipazione alla vita della comunità cristiana li aiuti a far maturare in loro il significato vero, consapevole e profondo del «per sempre», da viversi nella storia e nella quotidianità come segno e fermento del regno di Dio che viene. La proposta che viene elaborata in questa riflessione dovrà naturalmente misurarsi sulle differenti possibilità delle situazioni concrete.

description: To constrain the conditions for very early nucleosynthesis in the Universe we compare the chemical enrichment pattern of an extremely metal-poor damped Lyman alpha (DLA) absorber with predictions from recent explosive nucleosynthesis model calculations. For this, we have analyzed chemical abundances in the DLA system at z_abs=2.6183 toward the quasar Q0913+072 (z_em=2.785) using public UVES/VLT high spectral resolution data. The total neutral hydrogen column density in this absorber is logN(HI)=20.36. Accurate column densities are derived for CII, NI, OI, AlII, SiII, and FeII. Upper limits are given for FeIII and NiII. With [C/H]=-2.83, [N/H]=-3.84, and [O/H]=-2.47, this system represents one of the most metal-poor DLA systems investigated so far. It offers the unique opportunity to measure accurate CNO abundances in a protogalactic structure at high redshift. Given the very low overall abundance level and the observed abundance pattern, the data suggest that the chemical evolution of this DLA system is dominated by one or at most a few stellar generations. With reference to numerical model calculations, the chemical abundances in the DLA system are consistent with an enrichment from a single starburst of a zero-metallicity population of massive stars (10-50 M_sun) exploding as core-collapse Supernovae (SNe), i.e., the classical Type II Supernovae (SNeII), and possibly as hyper-energetic (E>10^51erg) core-collapse Supernovae, so-called Hypernovae (HNe), as well. In contrast, models using non-zero metallicity progenitors or other explosion mechanisms, such as pair-instability Supernovae (PISNe) or Type Ia Supernovae (SNeIa), do not match the observed abundance pattern.

Simulating volume-controlled invasion of a non-wetting fluid in volumetric images using basic image processing tools

description: A new algorithm is presented for simulating volume-controlled invasion of a non-wetting phase into voxel images. This method is complementary to the traditional morphological image opening method which mimics pressure-based invasion. A key advantage of the volume-based approach is that all saturations between 0 and 1 can obtained rather than the irregularly and widely spaced saturation steps obtained by pressure-based methods. Because of the incremental increases in saturation, it becomes possible to correctly predict defending phase trapping, which is not the case when pressure-based steps are applied. The algorithm is validated against morphological image opening and obtains near perfect agreement at equal saturations as expected from theory. It is also demonstrated that a volume-controlled capillary pressure curve can be obtained that displays the characteristic jumps in capillary pressure, and moreover, the envelop of peak pressures yields the pressure-based capillary pressure obtained by morphological opening, so in fact the results of the proposed algorithm are a superset of the morphological approach. Finally, results are compared to multiphase lattice Boltzmann and qualitatively similar results were achieved in substantially less time. The lattice Boltzmann method is more flexible in terms of variable contact angle and inclusion of viscous effects, but for quasi-static volume-based injection of a non-wetting fluid, the proposed method is viable alternative.

description: The pressure for more affordable housing has resulted in intensification of residential development and biodiversity loss. Using seven medium-density housing developments in three New Zealand cities, we explore the relationship between medium-density and greenspace quality. We also compare the sites pre- and post-development to determine the extent of loss of permeable space. In six developments for which we had pre and post-data, percentage loss ranged from 12% to 67%. The development with the highest housing density (82 units/ha) had very poor vegetation quality. However, there was no correlation between density and vegetation quality for those with less than 60 units/ha, indicating potential for improving the ecological value of permeable areas. Medium-density developments prioritising communal space had the highest provision of permeable space. We offer some recommendations on the application of biodiverse-sensitive design and planning principles to support biodiverse human living environments.

We have found evidence for an excess of Seyfert galaxies and LINERs among polar-ring galaxies compared to ordinary objects. The observed nuclear activity of polar-ring galaxies may be associated with the accretion of gas from the region of the polar structures onto the central galaxies.

description: A general paradigm for describing classical (and semiclassical) gravity is presented. This approach brings to the centre-stage a holographic relationship between the bulk and surface terms in a general class of action functionals and provides a deeper insight into several aspects of classical gravity which have no explanation in the conventional approach. After highlighting a series of unresolved issues in the conventional approach to gravity, I show that (i) principle of equivalence, (ii) general covariance and (iii)a reasonable condition on the variation of the action functional, suggest a generic Lagrangian for semiclassical gravity of the form $L=Q_a^{bcd}R^a_{bcd}$ with $\nabla_b Q_a^{bcd}=0$. The expansion of $Q_a^{bcd}$ in terms of the derivatives of the metric tensor determines the structure of the theory uniquely. The zeroth order term gives the Einstein-Hilbert action and the first order correction is given by the Gauss-Bonnet action. Any such Lagrangian can be decomposed into a surface and bulk terms which are related holographically. The equations of motion can be obtained purely from a surface term in the gravity sector. Hence the field equations are invariant under the transformation $T_{ab} \to T_{ab} + λg_{ab}$ and gravity does not respond to the changes in the bulk vacuum energy density. The cosmological constant arises as an integration constant in this approach. The implications are discussed.

These experiments examined solutions at millimolar concentrations of N-Acetyl-Aspartate (NAA), Choline (Clio), Creatine (Cr), and myo-Inositol (mI). The 1H NMR signal from these metabolites varied linearly with their concentration. Various agar gels were made with an NAA solution. The T2 relaxation time of the water signal varied with gel strength. No correlation was seen with the NAA signal T2 time. The scaling factor between the spectroscopy signal and a modified CPMG sequence signal was 2.19 x 10 to the power of 5. Theoretical justification is given for choosing TE and TR times for the MRS protocol. The TE and TR times accurately described the water relaxation as was verified by other techniques. The protocol did not fully characterize the metabolites and the quantification method over-estimated their concentrations.

description: Το κλίμα της Γης έχει αποδεδειγμένα αλλάξει μετά την προβιομηχανική εποχή. Κυρίως ενοχοποιείται το διοξείδιο του άνθρακα (CO2) λόγω της αύξησης της συγκέντρωσής του στην ατμόσφαιρα εξ αιτίας ανθρωπογενών δραστηριοτήτων. Τα δάση μέσω της φωτοσύνθεσης προσλαμβάνουν διοξείδιο του άνθρακα και με την αφομοίωση τον μετατρέπουν σε γλυκόζη (υδατάνθρακες). Δεσμεύουν με τον τρόπο αυτό τον άνθρακα μέσα στην ξυλώδη μάζα τους και τον κατακρατούν για μεγάλα χρονικά διαστήματα. Ακόμη και μετά την υλοτομία τους ο άνθρακας διατηρείται μέσα στα ξύλινα προϊόντα για πάρα πολλά χρόνια, μέχρι την αποικοδόμησή τους. Τα δάση επομένως θεωρούνται ως αποτελεσματικές δεξαμενές συσσώρευσης άνθρακα. Τα δρυοδάση του Ν. Τρικάλων, που χαρακτηρίζεται ως κατ’ εξοχήν ορεινός, είναι πρεμνοφυή, υποβαθμισμένα και παράγουν μόνο καυσόξυλα και ξυλάνθρακες. Η αναγωγή είναι η διαδικασία με την οποία μετατρέπονται από πρεμνοφυή σε σπερμοφυή, δηλαδή σε δάση μεγάλων αποθεμάτων και παραγωγής πολύτιμης τεχνικής ξυλείας. Είναι επομένως παραπάνω από βέβαιο ότι αυτός ο τρόπος διαχείρισής τους θα συμβάλλει στην άμβλυνση του φαινομένου θερμοκηπίου επηρεάζοντας τον κύκλο του άνθρακα με τη διττή δράση (της δέσμευσης και της κατακράτησης και διατήρησής του άνθρακα για πολλά χρόνια στη βιομάζα του). Γιαυτό επιβάλλεται η άμεση εφαρμογή της αναγωγής στα δημόσια δρυοδάση του νομού και η συμμόρφωση με την υπάρχουσα νομοθεσία και ο καθορισμός κινήτρων για τους δασοκτήμονες των ιδιωτικών δασών.
description: The Earth's climate has evidently changed since the pre-industrial era. Carbon dioxide (CO2) is mostly implicated due to its increased concentration in the atmosphere as a result of human activities. The forests through photosynthesis employ carbon dioxide and convert the uptake to glucose (carbohydrates), thus binding the carbon in the wood mass and detain it for long periods. Even after logging the carbon is held within wood products for many years until their degradation. Forests are therefore considered as effective reservoirs of carbon accumulation. The oak forests of the Prefecture of Trikala, which is characterized as predominantly mountainous are coppice, degraded and only produce firewood and charcoal. The conversion is the process by which they are converted from coppice to large forest stocks and forests of production of valuable technique timber. It is therefore more than likely that this method of management will help mitigate the greenhouse effect by influencing the carbon cycle through its dual action (sequestration, retention and preservation of carbon for many years in its biomass). So an immediate application of conversion in public oak forests of the prefecture and compliance with the existing legislation and the establishment of incentives for forest owners of private forests is of prime importance.

description: Abstract

Steam boilers are used in many industry sectors, such as the food industry, textile mill, paper factory, sugar mill, oil field, power plants and other industries. Boiler explosion is a very widespread problem that can be easily averted by just keeping a log of boiler data and understanding its behavioural trends in real time systems. Since these data are not accessible nor is properly recorded, every year lots of avoidable boiler explosions still occur. This project devises a strategy to solve this issue by tracking all the vital readings from a boiler and documenting it. Over a period of time, boiler operating logs help distinguish operating trends that can allow problems to be diagnosed, and boiler system maintenance to be scheduled, before an emergency shutdown is necessary. For instance, a steady rise in stack temperature, at the same boiler load, indicates dirty boiler firesides or waterside scale build-up. In either case, remedial action can be taken before it is necessary to shut the unit down for cleaning. This data will be collected by using an Arduino UNO R3 microcontroller and then accordingly a servo motor is rotated so that the right number of substances are sent into the boiler.

description: In this paper we develop a dressing method for constructing and solving some classes of matrix quasi-linear Partial Differential Equations (PDEs) in arbitrary dimensions. This method is based on a homogeneous integral equation with a nontrivial kernel, which allows one to reduce the nonlinear PDEs to systems of non-differential (algebraic or transcendental) equations for the unknown fields. In the simplest examples, the above dressing scheme captures matrix equations integrated by the characteristics method and nonlinear PDEs associated with matrix Hopf-Cole transformations.

description: A typical quantum state with no symmetry can be realized by letting a random unitary act on a fixed state, and the subsystem entanglement spectrum follows the Laguerre unitary ensemble (LUE). For integer-spin time reversal symmetry, we have an analogous scenario where we prepare a time-reversal symmetric state and let random orthogonal matrices act on it, leading to the Laguerre orthogonal ensemble (LOE). However, for half-integer-spin time reversal symmetry, a straightforward analogue leading to the Laguerre symplectic ensemble (LSE) is no longer valid due to that time reversal symmetric state is forbidden by the Kramers' theorem. We devise a system in which the global time reversal operator is fractionalized on the subsystems, and show that LSE arises in the system. Extending this idea, we incorporate general symmetry fractionalization into the system, and show that the statistics of the entanglement spectrum is decomposed into a direct sum of LOE, LUE, and/or LSE. Here, various degeneracies in the entanglement spectrum may appear, depending on the non-Abelian nature of the symmetry group and the cohomology class of the non-trivial projective representation on the subsystem. Our work establishes the entanglement counterpart of the Dyson's threefold way for Hamiltonians with symmetries.

description: We present a study of the Nernst effect in amorphous superconducting thin films of Nb$_{0.15}$Si$_{0.85}$. The field dependence of the Nernst coefficient above T$_{c}$ displays two distinct regimes separated by a field scale set by the Ginzburg-Landau correlation length. A single function $F(ξ)$, with the correlation length as its unique argument set either by the zero-field correlation length (in the low magnetic field limit) or by the magnetic length (in the opposite limit), describes the Nernst coefficient. We conclude that the Nernst signal observed on a wide temperature ($30 \times T_c$) and field ($4 \times B_{c2}$) range is exclusively generated by short-lived Cooper pairs.

Shuttling of a functional cre recombinase gene into mammalian cells using a retroviral vector
Creators: name: Hendry, Jerrod
Publisher: name: University of British Columbia
Year: 2009

description: Cre recombinase of bacteriophage PI has become a useful tool for molecular biological studies in vivo as well as in vitro. The Cre protein is an essential part of a system which catalyzes recombination between specific DNA sequence repeats called loxP sites. This recombination system allows for excision or inversion, depending on loxP orientation, Of DNA sequences flanked by loxP sites. In order to utilize the recombinase in mammalian systems, the retroviral vectors, LXSN and LXSHD, have been incorporated into the production of shuttle vectors and retroviral producing cell lines. The produced retroviruses allow for the transfer into and expression of the Cre recombinase in mammalian cells. These newly constructed retroviral particles will be a useful tool for inducing specific gene ablation in infective mammalian cells.

description: We report the ground-level detection of a Galactic Cosmic-Ray (GCR) flux enhancement lasting $\sim$ 17 hr and associated with the passage of a magnetic flux rope (MFR) over the Earth. The MFR was associated with a slow Coronal Mass Ejection (CME) caused by the eruption of a filament on 2016 October 9. Due to the quiet conditions during the eruption and the lack of interactions during the interplanetary CME transport to the Earth, the associated MFR preserved its configuration and reached the Earth with a strong magnetic field, low density, and a very low turbulence level compared to the local background, thus generating the ideal conditions to redirect and guide GCRs (in the $\sim$ 8 to 60 GV rigidity range) along the magnetic field of the MFR. An important negative $B_Z$ component inside the MFR caused large disturbances in the geomagnetic field and a relatively strong geomagnetic storm. However, these disturbances are not the main factors behind the GCR enhancement. Instead, we found that the major factor was the alignment between the MFR axis and the asymptotic direction of the observer.

description: Η εκπαίδευση των μαθητών με νοητική ανεπάρκεια έχει δύο πόλους. Ο πρώτος αφορά την εκπαίδευση στο γνωστικό κομμάτι και εκπροσωπεί την εκπαιδευτική πολιτική και ο δεύτερος την κοινωνική εκπαίδευση και αφορά την ικανοποίηση των αναγκών των μαθητών για εκπαίδευση στις κοινωνικές δεξιότητες και κοινωνικές σχέσεις. Ο σκοπός της έρευνας μας είναι να απαντήσουμε στο ποια είναι η άποψη των εκπαιδευτικών και των γονέων για την εκπαίδευση των παιδιών με νοητική ανεπάρκεια. Διερευνήσαμε με λοιπόν το νόημα που προσδίδουν αυτές οι δύο ομάδες των σημαντικών ενηλίκων στην εκπαίδευση των παιδιών με νοητική ανεπάρκεια. Έτσι λοιπόν επιλέξαμε 10 παιδιά με διαγνωσμένη νοητική ανεπάρκεια και πήραμε συνεντεύξεις από τους εκπαιδευτικούς των Τμημάτων Ένταξης των Δημοτικών Σχολείων που φοιτούν και από τους γονείς τους. Οι εκπαιδευτικοί μέσα από την εκπαιδευτική τους πράξη μας φανερώνουν το νόημα που αποδίδουν οι ίδιοι στην εκπαίδευση των παιδιών με νοητική ανεπάρκεια ενώ οι γονείς μέσα από την επιθυμία τους και την αξιολόγηση της εκπαίδευσης που λαμβάνουν τα παιδιά.
description: The education of students with mental retardation has two poles. First concerns the education in the cognitive piece and represents the educational policy and second the social education and concerns the satisfaction of needs of students for education in the social dexterities and social relations. The aim of our research is to answer in who it is the opinion of teachers and parents for the education of children with mental retardation. We investigated with therefore the meaning that they lend these two teams of important adults in the education of children with mental retardation. Thus therefore we selected 10 children with diagnosed intellectual insufficiency and we took interviews from the teachers of Departments of Integration of Municipal Schools that study also from their parents. The teachers through their educational action reveal the meaning that attribute the himself in the education of children with mental retardation while the parents through their wish and the evaluation of education that receives the children.
