description: Reliable estimates of neutrino-nucleus reactions in the resonance-excitation region play an important role in many of the on-going and planned neutrino oscillation experiments. We study here neutrino-nucleus reactions in the delta-particle excitation region with the use of neutrino pion-production amplitudes calculated in a formalism in which the resonance contributions and the background amplitudes are treated on the same footing. Our approach leads to the neutrino-nucleus reaction cross sections that are significantly different from those obtained in the conventional approach wherein only the pure resonance amplitudes are taken into account. To assess the reliability of our formalism, we calculate the electron-nucleus scattering cross sections in the same theoretical framework; the calculated cross sections agree reasonably well with the existing data.

Mechanistic studies on [alpha]-glycosyl transferases

Publisher: name: University of British Columbia

description: In order to provide insight into the mechanism of glycogen phosphorylase (phos b) and cyclodextrin glycosyltransferase (CGTase) the modified substrates, 4-deoxy-α-maltotriosyl fluoride (4DαG3F), 4-deoxymaltopentaose (4DG5), and 4-deoxymaltohexaose (4DG6) have been synthesized using chemical and enzymatic means. These types of incompetent substrate analogues can be used to "trick" each enzyme into catalyzing only the first half of its normal reaction in order to trap a glycosyl-enzyme intermediate. Glycosyl fluorides such as α-maltotriosyl fluoride (αG3F) are good substrates for Bacillus circulans 251 CGTase (kcat = 275 s⁻¹, Km = 2.5 mM) providing a convenient method of measurement. Reaction of the acid/base catalyst mutant of CGTase, Glu257Gln, with 4DαG3F, yielded a stable glycosyl-enzyme intermediate. Using neutral loss mass spectrometry, Asp229 was identified as the catalytic nucleophile. An X-ray structure of the 4- deoxymaltotriosyl moiety bound to Glu257Gln provided the first structural insights into such a covalent intermediate for any a-1,4 glycosyl transferase or α-glycosidase. The binding of active site mutants of CGTase to the inhibitor acarbose was investigated through measurement of Ki values. Kinetic parameters for αG3F and α-glucosyl fluoride were determined and reasonable correlations were observed in logarithmic plots relating the Ki value for acarbose with each mutant and both kcat/Km and Km for the hydrolysis of either substrate by the corresponding mutants. The dependence was greater in the plot of log (kcat/Km) vs log Ki than in the plot of log Km indicating that the binding mode of acarbose more closely resembles that of the reaction transition state than of the ground state. Kinetic results on phos b indicated that 4DG6 was a competitive inhibitor with respect to maltopentaose, but binds noncompetitively with respect to orthophosphate or glucose-1- phosphate. Two trapping experiments in the presence of 4DG6, a radiolabelling study using ¹⁴C-glucose-1-phosphate and an electrospray mass spectrometry investigation, provided preliminary evidence for a glycosyl-enzyme intermediate. Analogous experiments were performed with potato phosphorylase using 4DG5 yielding similar results. Positional isotope exchange experiments were attempted with both phosphorylases. Glucose-1-phosphate selectively labelled with ¹⁸O at the anomeric position was chemically synthesized for this purpose and ³¹PNMR was used to follow the extent of isotope exchange.

description: The neutron polarization of the NG-C beamline at the NIST Center for Neutron Research was measured as part of the aCORN neutron beta decay experiment. Neutron transmission through a polarized 3He spin filter cell was recorded while adiabatic fast passage (AFP) nuclear magnetic resonance (NMR) reversed the polarization direction of the 3He in an eight-step sequence to account for drifts. The dependence of the neutron transmission on the spin filter direction was used to calculate the neutron polarization. The time dependent transmission was fit to a model which included the neutron spectrum, and 3He polarization losses from spin relaxation and AFP-NMR. The polarization of the NG-C beamline was found to be ${\mid}P_\mathrm{n}{\mid} \leq 4\times 10^{-4}$ with 90 % confidence.

description: We theoretically show that materials with perovskite-type crystal structures provide a platform for spin current generation, taking advantage of a mechanism requiring neither the spin-orbit coupling nor a ferromagnetic moment, but is based on spin-split band structures in certain kinds of collinear antiferromagnetic states. By investigating a multiband Hubbard model for transition metal compounds by means of the Hartree-Fock approximation and the Boltzmann transport theory, we find that a pure spin current is induced by an electric field applied to a C-type antiferromagnetic metallic phase. The spin current generation originates from a cooperative effect of spatially anisotropic electron transfer integrals owing to the GdFeO$_3$-type lattice distortion, which is ubiquitous in many perovskites, and the collinear spin configuration. We discuss our finding from the symmetry point of view, in comparison with other spin current generator candidates with collinear antiferomagnetism. We also propose several ways to detect the phenomenon in candidate perovskite materials.

description: The dissipation effect in a hybrid system is studied in this Letter. The hybrid system is a compound of a classical magnetic particle and a quantum single spin. Two cases are considered. In the first case, we investigate the effect of the dissipative quantum subsystem on the motion of its classical partner. Whereas in the second case we show how the dynamics of the quantum single spin are affected by the dissipation of the classical particle. Extension to general dissipative hybrid systems is discussed.

description: We present CCD photometric and mass function study of 9 young Large Magellanic Cloud star clusters namely NGC 1767, NGC 1994, NGC 2002, NGC 2003, NGC 2006, SL 538, NGC 2011, NGC 2098 and NGC 2136. The BVRI data reaching down to V ~ 21 mag, are collected from 3.5-meter NTT/EFOSC2 in sub-arcsec seeing conditions. For NGC 1767, NGC 1994, NGC 2002, NGC 2003, NGC 2011 and NGC 2136, broad band photometric CCD data are presented for the first time. Seven of the 9 clusters have ages between 16 to 25 Myr while remaining two clusters have ages $32\pm4$ Myr (NGC 2098) and $90\pm10$ Myr (NGC 2136). For 7 younger clusters, the age estimates based on a recent model and the integrated spectra are found to be systematically lower ($\sim$ 10 Myr) from the present estimate. In the mass range of $\sim 2 - 12$ $M_{\odot}$, the MF slopes for 8 out of nine clusters were found to be similar with the value of $γ$ ranging from $-1.90\pm0.16$ to $-2.28\pm0.21$. For NGC 1767 it is flatter with $γ= -1.23\pm0.27$. Mass segregation effects are observed for NGC 2002, NGC 2006, NGC 2136 and NGC 2098. This is consistent with the findings of Kontizas et al. for NGC 2098. Presence of mass segregation in these clusters could be an imprint of star formation process as their ages are significantly smaller than their dynamical evolution time. Mean MF slope of $γ= -2.22\pm0.16$ derived for a sample of 25 young ($\le 100$ Myr) dynamically unevolved LMC stellar systems provide support for the universality of IMF in the intermediate mass range $\sim 2-12 M_{\odot}$.

description: The current thesis presents the social and cultural phenomenon of multiculturalism or cultural pluralism within Greece, as well as internationally. It is made clear that the exploitation of the above-mentioned phenomenon within the limits of globalisation, combined with the hypocritical use of human rights and the promotion of the syncretist New Age movement, is aimed at the uniformity and homogenisation of all religious, cultural and ethnic expressions and traditions. At the same time, emphasis is bestowed on the important role that the great world religions and especially the Orthodox Church should play in the transgression of the national and local conflicts, as well as the restoration of social peace among the nations.
Optimal cost tuning of frustration: Achieving desired states in the Kuramoto-Sakaguchi model

description: There are numerous examples of studied real-world systems that can be described as dynamical systems characterized by individual phases and coupled in a network like structure. Within the framework of oscillatory models, much attention has been devoted to the Kuramoto model, which considers a collection of oscillators interacting through a sinus function of the phase differences. In this paper, we draw on an extension of the Kuramoto model, called the Kuramoto-Sakaguchi model, which adds a phase lag parameter to each node. We construct a general formalism that allows to compute the set of lag parameters that may lead to any phase configuration within a linear approximation. In particular, we devote special attention to the cases of full synchronization and symmetric configurations. We show that the set of natural frequencies, phase lag parameters and phases at the steady state is coupled by an equation and a continuous spectra of solutions is feasible. In order to quantify the system's strain to achieve that particular configuration, we define a cost function and compute the optimal set of parameters that minimizes it. Despite considering a linear approximation of the model, we show that the obtained tuned parameters for the case of full synchronization enhance frequency synchronization in the nonlinear model as well.
Vertically Extended Neutral Gas in the Massive Edge-on Spiral NGC 5746

description: We present Very Large Array 21-cm observations of the massive edge-on spiral galaxy NGC 5746. This galaxy has recently been reported to have a luminous X-ray halo, which has been taken as evidence of residual hot gas as predicted in galaxy formation scenarios. Such models also predict that some of this gas should undergo thermal instabilities, leading to a population of warm clouds falling onto the disk. If so, then one might expect to find a vertically extended neutral layer. We detect a substantial high-latitude component, but conclude that almost all of its mass of 1.2-1.6 billion solar masses most likely resides in a warp. Four features far from the plane containing about 100 million solar masses are found at velocities distinct from this warp. These clouds may be associated with the expected infall, although an origin in a disk-halo flow cannot be ruled out, except for one feature which is counter-rotating. The warp itself may be a result of infall according to recent models. But clearly this galaxy lacks a massive, lagging neutral halo as found in NGC 891. The disk HI is concentrated into two rings of radii 1.5 and 3 arcminutes. Radial inflow is found in the disk, probably due to the bar in this galaxy. A nearby member of this galaxy group, NGC 5740, is also detected. It shows a prominent one-sided extension which may be the result of ram pressure stripping.

description: Relativistic electrons generated by the interaction of petawatt-class short laser pulses with solid targets can be used to generate bright X-rays via bremsstrahlung. The efficiency of laser energy transfer into these electrons depends on multiple parameters including the focused intensity and pre-plasma level. This paper reports experimental results from the interaction of a high intensity petawatt-class glass laser pulses with solid targets at a maximum intensity of $10^{19}$ W/cm$^2$. In-situ measurements of specularly reflected light are used to provide an upper bound of laser absorption and to characterize focused laser intensity, the pre-plasma level and the generation mechanism of second harmonic light. The measured spectrum of electrons and bremsstrahlung radiation provide information about the efficiency of laser energy transfer.
An Halpha-selected sample of cataclysmic variables -- II. Implications for CV evolution
Creators: name: Pretorius, Magaretha L.

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We use an independent new sample of cataclysmic variables (CVs), constructed by selecting objects for Halpha emission, to constrain the properties of the intrinsic CV population. This sample is restricted to systems that are likely to be non-magnetic and unevolved; it consists of 17 CVs, of which at least 10 have orbital periods above 3 h. We find that even very generous allowance for selection effects is not sufficient to reconcile the large ratio of short- to long-period CVs predicted by standard CV evolution theory with the observed sample, possibly implying that short-period systems evolve faster than predicted by the disrupted magnetic braking model. This would require that an angular momentum loss mechanism, besides gravitational radiation, acts on CVs with orbital periods below the period gap. To bring the model into agreement with observations, the rate of angular momentum loss below the period gap must be increased by a factor of at least 3, unless the model also over estimates the angular momentum loss rate of long-period CVs.

description: We fabricated epitaxial thin films of hexagonal DyMnO3, which otherwise form in a bulk perovskite structure, via deposition on Pt(111)//Al2O3 (0001) and YSZ(111) substrates: each of which has in-plane hexagonal symmetry. The polarization hysteresis loop demonstrated the existence of ferroelectricity in our hexagonal DyMnO3 films at least below 70 K. The observed 2.2 uC/cm^2 remnant polarization at 25 K corresponded to a polarization enhancement by a factor of 10 compared to that of the bulk orthorhombic DyMnO3. Interestingly, this system showed an antiferroelectric-like feature in its hysteresis loop. Our hexagonal DyMnO3 films showed an antiferromagnetic Neel temperature around 60 K and a spin reorientation transition around 40 K. We also found a clear hysteresis in the temperature dependence of the magnetization, which was measured after zero-field-cooling and field-cooling. This hysteresis may well have been of spin glass origin, which was likely to arise from the geometric frustration of antiferromagnetically-coupled Mn spins with an edge-sharing triangular lattice.
Vortex propagation and phase transitions in a chiral antiferromagnetic nanostripe

description: We study a vortex in a nanostripe of an antiferromagnet with easy-plane anisotropy and interfacial Dzyloshinskii-Moriya interaction. The vortex has hybrid chirality being Néel close to its center and Bloch away from it. Propagating vortices can acquire velocities up to a maximum value that is lower than the spin wave velocity. When the vortex is forced to exceed the maximum velocity, phase transitions occur to a nonflat spiral, vortex chain, and flat spiral, successively. The vortex chain is a topological configuration stabilised in the stripe geometry. Theoretical arguments lead to the general result that the velocity of localized excitations in chiral magnets cannot reach the spin wave velocity.

Studies towards the total synthesis of ionomycin
Creators: name: Daynard, Timothy S.
Publisher: name: University of British Columbia
Year: 2009

description: An optically pure precursor to ionomycin (1) consisting of the thirty two carbon backbone and protected functional groups of the target molecule was synthesized by the coupling of two subunits between C₁₅ and C₁₆ via the Suzuki reaction. An enantioselective route to the C₁₁-C₁₅ fragment 57 was developed. This unit was coupled to the C₁-C₁₀ fragment 53 to provide the left half 162a (C₁-C₁₅) of the target molecule. Hydroboration of this 2-methyl terminal alkene with 9-BBN generated an asymmetric center at C₁₄ and provided the alkylborane moiety necessary for the Suzuki coupling reaction. The resulting alkylborane was reacted with the alkenyl iodide fragment 200 (C1₆-C₃₂) in the presence of the palladium catalyst PdCI₂(dppf) and sodium hydroxide to afford the coupled products 203a,b in 79% yield with the stereochemistry about the double-bond exclusively E and as a 57:43 mixture of epimers about C₁₄.
Merging of globular clusters within inner galactic regions. II. The Nuclear Star Cluster formation

description: In this paper we present the results of two detailed N-body simulations of the interaction of a sample of four massive globular clusters in the inner region of a triaxial galaxy. A full merging of the clusters takes place, leading to a slowly evolving cluster which is quite similar to observed Nuclear Clusters. Actually, both the density and the velocity dispersion profiles match qualitatively, and quantitatively after scaling, with observed features of many nucleated galaxies. In the case of dense initial clusters, the merger remnant shows a density profile more concentrated than that of the progenitors, with a central density higher than the sum of the central progenitors central densities. These findings support the idea that a massive Nuclear Cluster may have formed in early phases of the mother galaxy evolution and lead to the formation of a nucleus, which, in many galaxies, has indeed a luminosity profile similar to that of an extended King model. A correlation with galactic nuclear activity is suggested.

description: Αντικείμενο της παρούσας εργασίας είναι η αξιολόγηση της Πρωτοβουλίας LEADER+ της τρίτης προγραμματικής περιόδου, με την Ανάλυση Απόκλισης – Συμμετοχής (Shift – Share Analysis). Η μέθοδος αυτή κατατάσσει και συγκρίνει τις 40 Ομάδες Τοπικής Δράσης μεταξύ τους, οι οποίες δραστηριοποιήθηκαν σε εθνικό επίπεδο, αναλύοντας την απορρόφηση των κονδυλίων έκαστης. Έτσι, προκύπτουν συμπεράσματα για αδυναμίες και πλεονεκτήματα, τόσο σε τοπικό όσο και σε εθνικό/κοινοτικό επίπεδο.Τα αποτελέσματα της έρευνας φανερώνουν ευνοϊκή επίδραση της διάρθρωσης του Εθνικού Προγράμματος της LEADER+, για τις 21 από τις 40 ΟΤΔ, που την υλοποιούν. Από αυτές, οι 9 αξιοποιούν πλήρως το πλεονέκτημα αυτό, οι 2 επωφελούνται του πλεονεκτήματος, εξουδετερώνοντας την ελλιπή διαχείρισή τους, ενώ οι υπόλοιπες 10 δεν επωφελούνται του πλεονεκτήματος. Από τις 19 ΟΤΔ, για τις οποίες η διάρθρωση του Εθνικού Προγράμματος δεν είναι ευνοϊκή, οι 7 έχουν αναστρέψει τις αρνητικές προϋποθέσεις, η μία αντιμετωπίζει, αλλά όχι επαρκώς τις δυσμενείς προϋποθέσεις, ενώ οι υπόλοιπες 11 επιδεικνύουν αρνητικές, συγκριτικά, ικανότητες αντιμετώπισης της διαρθρωτικής αδυναμίας του Προγράμματος.Από τα αποτελέσματα συμπεραίνεται η ανάγκη διερεύνησης των αιτίων της μη ικανοποιητικής επίδοσης ορισμένων ΟΤΔ, αλλά και η επανεξέταση του βαθμού αποκέντρωσης της προσέγγισης «από τη βάση προς την κορυφή» της Πρωτοβουλίας LEADER+.
description: The aim of the present work was the evaluation of the project (initiative) “LEADER+” (3rd programmatic period), using the Shift - Share Analysis. With this method, forty (40) “Local Action Groups” (LAGs) were classified and compared, analyzing the absorption of their budgets, in order to dissect advantages and possible weak points of the structure of this project (initiative), at national and European Community level, as well as in local management.Results indicated a favorable effect of the project for 21 out of the 40 “Local Action Groups”. Among them, 9 took full advantage, 2 counteracted their incomplete management, while no profit for 10 LAGs was monitored. Among the 19 LAGs for which the structure of National Program was not favorable, 7 of them inverted (but not sufficiently) the negative conditions, while 11 of them demonstrated negative results.Overall, results of the present thesis indicated an accumulating need to further investigate the reasons for which many Local Action Groups did not take advantage of this project and additionally to reconsider the degree of decentralization within the “bottom – up” approach of the studied project (initiative).
On the Chermnykh-Like Problems: I. The Mass Parameter μ=0.5

description: Following Papadakis (2005)'s numerical exploration of the Chermnykh's problem, we here study a Chermnykh-like problem motivated by the astrophysical applications. We find that both the equilibrium points and solution curves become quite different from the ones of the classical planar restricted three-body problem. In addition to the usual Lagrangian points, there are new equilibrium points in our system. We also calculate the Lyapunov Exponents for some example orbits. We conclude that it seems there are more chaotic orbits for the system when there is a belt to interact with.

Emerging singularities in the bouncing loop cosmology

description: In this paper we calculate $\mathcal{O}(μ^4)$ corrections from holonomies in the Loop Quantum Gravity, usually not taken into account. Allowance of the corrections of this kind is equivalent with the choice of the new quatization scheme. Quantization ambiguities in the Loop Quantum Cosmology allow for this additional freedom and presented corrections are consistent with the standard approach. We apply these corrections to the flat FRW cosmological model and calculate the modified Friedmann equation. We show that the bounce appears in the models with the standard $\mathcal{O}(μ^2)$ quantization scheme is shifted to the higher energies $ρ_{\text{bounce}} = 3 ρ_{\text{c}}$. Also a pole in the Hubble parameter appears for $ρ_{\text{pole}} = {3/2} ρ_{\text{c}}$ corresponding to \emph{hyper-inflation/deflation} phases. This pole represents a curvature singularity at which the scale factor is finite. In this scenario the singularity and bounce co-exist. Moreover we find that an ordinary bouncing solution appears only when quantum corrections in the lowest order are considered. Higher order corrections can lead to the nonperturbative effects.

Intersecting non-SUSY $p$-brane with chargeless 0-brane as black $p$-brane

description: Unlike BPS $p$-brane, non-supersymmetric (non-susy) $p$-brane could be either charged or chargeless. As envisaged in [hep-th/0503007], we construct an intersecting non-susy $p$-brane with chargeless non-susy $q$-brane by taking T-dualities along the delocalized directions of the non-susy $q$-brane solution delocalized in $(p-q)$ transverse directions (where $p\geq q$). In general these solutions are characterized by four independent parameters. We show that when $q=0$ the intersecting charged as well as chargeless non-susy $p$-brane with chargeless 0-brane can be mapped by a coordinate transformation to black $p$-brane when two of the four parameters characterizing the solution take some special values. For definiteness we restrict our discussion to space-time dimensions $d=10$. We observe that parameters characterizing the black brane and the related dynamics are in general in a different branch of the parameter space from those describing the brane-antibrane annihilation process. We demonstrate this in the two examples, namely, the non-susy D0-brane and the intersecting non-susy D4 and D0-branes, where the solutions with the explicit microscopic descriptions are known.

description: In recent years, there has been an increased interest in the application of Natural Language Processing (NLP) to legal documents. The use of convolutional and recurrent neural networks along with word embedding techniques have presented promising results when applied to textual classification problems, such as sentiment analysis and topic segmentation of documents. This paper proposes the use of NLP techniques for textual classification, with the purpose of categorizing the descriptions of the services provided by the Public Prosecutor's Office of the State of Paraná to the population in one of the areas of law covered by the institution. Our main goal is to automate the process of assigning petitions to their respective areas of law, with a consequent reduction in costs and time associated with such process while allowing the allocation of human resources to more complex tasks. In this paper, we compare different approaches to word representations in the aforementioned task: including document-term matrices and a few different word embeddings. With regards to the classification models, we evaluated three different families: linear models, boosted trees and neural networks. The best results were obtained with a combination of Word2Vec trained on a domain-specific corpus and a Recurrent Neural Network (RNN) architecture (more specifically, LSTM), leading to an accuracy of 90\% and F1-Score of 85\% in the classification of eighteen categories (law areas).

Τέλος γίνεται σύντομη αναφορά στη χρησιμοποίηση της αλληλογραφίας στην πολεμική των Εκκλησιών μεταξύ τους.
description: In this postgraduate thesis we present the theological dialogue during the years 1573-1581 between the Tubingen theologians and the Ecumenical Patriarch Jeremiah II from the aspect of the Western theological tradition. After the summary description of the historical context, through which the Reformation was emerged, we present the position of the Reformation over the Orthodox Church and vice versa before the beginning of the correspondence. Then we describe the historical progress of the correspondence and we make a theological analysis of all the points of disagreement that arose, laying emphasis on the Lutheran theological approach of each one of them. Finally we give a brief account of the way the correspondence was used in the polemics among the Church both in West and East.

description: Star formation rates (SFRs) obtained via extinction corrected H alpha are compared to dense gas as traced by CO(J=3-2) emission at the centers of nearby galaxies, observed with the ASTE telescope. It is found that, although many of the observed positions are dusty and therefore heavily absorbed at H alpha, the SFR shows a striking correlation with dense gas in the form of the Schmidt law with an index 1.0. The correlation is also compared between gas traced by CO(J=1-0) and application of H alpha extinction correction. We find that dense gas produces a far better correlation with SFR in view of surface density values.

Tunneling through molecules and quantum dots: master-equation approaches

description: An important class of approaches to the description of electronic transport through molecules and quantum dots is based on the master equation. We discuss various formalisms for deriving a master equation and their interrelations. It is shown that the master equations derived by Wangsness, Bloch, and Redfield and by Koenig et al. are equivalent. The roles of the large-reservoir and Markov approximations are clarified. The Markov approximation is traced back to nonzero bias voltage and temperature, whereas interactions and the corresponding rapid relaxation in the leads are shown to be irrelevant for the transport under certain conditions. It is explained why the T-matrix formalism gives incomplete results except for diagonal density operators and to second order in the tunneling amplitudes. The time-convolutionless master equation is adapted to tunneling problems and a diagrammatic scheme for generating arbitrary orders in the tunneling amplitudes is developed.
