description: Η εργασία εκπονήθηκε στον Τομέα Λαογραφίας του Τμήματος Ιστορίας και Αρχαιολογίας της Φιλοσοφικής Σχολής του Α.Π.Θ .Αξιοποιείται η Προφορική Ιστορία, προσφιλής στις Κοινωνικές Επιστήμες, όπως η Κοινωνική Ανθρωπολογία και η Λαογραφία. Γίνεται χρήση του σχήματος’’ εμείς και οι άλλοι’’ ,σημαντικού μεθοδολογικού εργαλείου στις Κοινωνικές Επιστήμες. Η παρούσα μεταπτυχιακή εργασία μελετά μέσω συνεντεύξεων και βιβλιογραφικής τεκμηρίωσης την έννοια της ταυτότητας και του περιεχομένου της ελληνικής συνείδησης μιας ομάδας παλιννοστησάντων ομογενών από την πρώην Ε.Σ.Σ.Δ κατά την περίοδο των ετών 1991-1998.Οι πληροφορητές ομογενείς παλιννοστήσαντες έχουν από την αρχή της έλευσής τους εγκατασταθεί σε έναν συνοικισμό του Ε.Υ.Α.Π.Ο.Ε στο χωριό Ζυγός Καβάλας.Η προσέγγιση των πληροφορητών έγινε με βάση τη δομημένη συνέντευξη πάνω σε ερωτήματα που αφορούσαν το παρελθόν και το παρόν της ζωής τους. Μέσα από την ανάλυση των παρεχομένων πληροφοριών προσεγγίζεται η ταυτότητά τους ,τα προβλήματα μετάβασης από τη ζωή σε μια χώρα στην άλλη ,οι τρόποι που αντιμετωπίζεται το πολιτισμικό χάσμα της μετανάστευσης. Πρέπει να δηλωθεί ότι οι 33 πληροφορητές δεν προέρχονται από τις ίδιες περιοχές της Σοβιετικής Ένωσης ,αλλά από διαφορετικές πρώην Ομόσπονδες σοσιαλιστικές Δημοκρατίες.(Ουζμπεκιστάν ,Καζακστάν, Κιργιζία, Γεωργία, Αρμενία ,Ρωσία κ.λ.π
description: This work was done on the Department of Folklore and Social Anthropology of the School of History and Archaeology of the Faculty of Philosophy the Aristoteles University of Thessaloniki .By this way the Oral History ,which is favourite to the Social Sciences ,such as Social Antropology and Folklore is turned to advantage. The use of the saying “ we and the others” states the fact of how important methological tool this is in the Social Sciences.The present masterthesis studies through interviews and book documentation the sense of Identification and greek conscience of a group of home coming Greeks from the former U. S.S.R during the period of 1991 to 1998.These people established their staying in a settlement given to them by E.I.Y.A.P.O.E(National Foundation for the Reception and Resettlement of Repatriated Greeks ).Actually in the village of Zygos in Kavala .Our approach to them was based on a questionnaire referring to their past and present life. We must point out that the 33 people questioned do not come from the same regions of the Soviet Union ,but from different ex Socialist Democratic Federations such as Armenia ,Georgia ,Kirgisia, Uzbekistan, Kazakhstan e.t.c.

description: We propose a Raman spectroscopy technique which is able to probe the one-particle Green's function, the Fermi surface, and the quasiparticles of a gas of strongly interacting ultracold atoms. We give quantitative examples of experimentally accessible spectra. The efficiency of the method is validated by means of simulated images for the case of a usual Fermi liquid as well as for more exotic states: specific signatures of e.g. a d-wave pseudo-gap are clearly visible.

description: In addition to rather complicated general methods it is interesting and valuable to develop fast efficient methods for calculating generators of power integral bases in special types of number fields. We consider sextic fields containing a real cubic and a complex quadratic fields. We develop a very simple and very efficient method to calculate generators of power integral bases in this type of fields. Our method can be applied to infinite families of number fields, as well. We substantially improve the former methods. Our algorithm is illustrated with detailed examples, involving infinite parametric families.
High pt Measurements at the CERN SPS

description: The current experimental situation concerning high pt observables at the CERN SPS is reviewed. Recent data from the NA45, NA49 and NA57 collaborations are discussed and compared to earlier measurements by WA98 and NA45 at the same center-of-mass energies, as well as to measurements at the higher energies by the RHIC experiments. The observables include new p+p, A+A spectra, nuclear modification factors (R_AA, R_CP), two particle azimuthal correlations, and baryon to meson ratios at moderately high pt. Generally, the interpretation of the SPS data suffers from the lack of reliable baseline measurements (p+p and p+A). However, the overall picture that is emerging suggests that already at SPS energies medium effects similar to those observed at RHIC are present.

description: In this paper, we propose EasyBO, an Efficient ASYnchronous Batch Bayesian Optimization approach for analog circuit synthesis. In this proposed approach, instead of waiting for the slowest simulations in the batch to finish, we accelerate the optimization procedure by asynchronously issuing the next query points whenever there is an idle worker. We introduce a new acquisition function that can better explore the design space for asynchronous batch Bayesian optimization. A new strategy is proposed to better balance the exploration and exploitation and guarantee the diversity of the query points. And a penalization scheme is proposed to further avoid redundant queries during the asynchronous batch optimization. The efficiency of optimization can thus be further improved. Compared with the state-of-the-art batch Bayesian optimization algorithm, EasyBO achieves up to 7.35 times speed-up without sacrificing the optimization results.

De la crónica a la escena : Arauco en el teatro del Siglo de Oro

Publisher: name: University of British Columbia
Year: 2008

description: The encounter between Spain and the New World --the Americas-- is one of the distinctive historical events of the 15th century. So it is surprising that there is very little reference to the Americas in the many plays remaining from the Spanish Golden Age theatre. This thesis studies six plays centering on the Arauco wars in Southern Chile and the figure of one of the first governors of that country, don Garcia Hurtado de Mendoza. The main objective of this study is to demonstrate to what extent the literary elaboration of the topic contributed to the vision of the New World held by the Spanish public. The dramatists that dealt with this theme did not have any direct contact with the Americas, therefore their representation of that world was based on oral accounts and literary sources available at the time. Among the latter are the letters of a conqueror, two chronicles, two epic poems and a panegiric text. The first part of this thesis consists of the textual analysis of this literary corpus. The main focus of the analysis is the influence of these sources on the dramas and how the characteristics of each genre contributed to their creation. The analysis of the dramatic works with Araucanian content (five plays and one auto sacramental) forms the second part of this thesis. The approach centers particularly on the representation of the Indian world as the "Other" opposed to the Spanish world. The analysis of these texts shows the subtle evolutionary process by which the treatment of the historical fact --Arauco and the Conquest-- in the theatre contributed to create the "idea" of America held at the time in Spain. Also, the re-elaboration of characters and motives indicates the emergence of native mythical figures which have become part of the historic and cultural patrimony of Chile today.

description: In this paper, we have used the state finder hierarchy for Barrow holographic dark energy (BHDE) model in the system of the FLRW Universe. We apply two DE diagnostic tools to determine $ΛBHDE$ model to have various estimations of $\triangle$. The first diagnostic tool is the state finder hierarchy in which we have studied $S^{(1)}_{3}$ $S^{(1)}_{4}$, $S^{(2)}_{3}$ $S^{(2)}_{4}$ and second is the composite null diagnostic (CND) in which the trajectories ( $S^{(1)}_{3} - ε$), ($S^{(1)}_{4}-ε$), ($S^{(2)}_{3}-ε$)($S^{(2)}_{4}-ε$) are discussed, where $ε$ is fractional growth parameter. The infrared cut-off here is taken from the Hubble horizon. Finally, together with the growth rate of matter perturbation, we plot the state finder hierarchy that determines a composite null diagnosis that can differentiate emerging dark energy from $ΛCDM$. In addition, the combination of the hierarchy of the state finder and the fractional growth parameter has been shown to be a useful tool for diagnosing BHDE, particularly for breaking the degeneracy with different parameter values of the model.

description: Female C57BL/6 mice weighing between 18 and 20 grams at eight weeks of age were used in this study. The mice were housed in polycarbonate cages in an air-conditioned room with RT , humidity (~50%) and light/dark cycle for 12 h. The spinal cord injury model was constructed using an Infinite Horizons impactor at the eighth thoracic vertebra (T8). 11 mice were divided into 4 groups: 3 sham, 3 injured and 5 treated with Ce@UCNP-BCH post-injury, and all mice were harvested in the subacute phase (10 dpi) for snATAC-seq and snRNA-seq (BGI DNBelab C4) . Single-cell ATAC/RNA sequencing was performed using the DNBelab C Series Single-Cell ATAC Library Prep Set (MGI, 1000021878) and the DNBelab C Series High-throughput Single-Cell Library Preparation Kit (MGI, 940-000047-00) according to the kit instructions. Approximately 10,000-12,000 nuclei were loaded into each chip, 3,000-8,000 nuclei were recovered per sample, and libraries were sequenced to a minimum depth of 50,000 reads per nucleus using the MGI DNBSEQ-T7 platform. Raw sequencing reads were demultiplexed, aligned, and a count matrix or fragment files was generated using DNBelab_C_Series_HT_scRNA-analysis-software (https://github.com/MGI-tech-bioinformatics/DNBelab_C_Series_HT_scRNA-analysis-software). For alignment, we used the reference genome (mm10) and specifically, we used a pre-messenger-RNA reference for nuclear RNA.
Density-functional theory study of half-metallic heterostructures: interstitial Mn in Si

description: Using density-functional theory within the generalized gradient approximation, we show that Si-based heterostructures with 1/4 layer $δ$-doping of {\em interstitial} Mn (Mn$_{\mathrm int}$) are half-metallic. For Mn$_{\mathrm int}$ concentrations of 1/2 or 1 layer, the states induced in the band gap of $δ$-doped heterostructures still display high spin polarization, about 85% and 60%, respectively. The proposed heterostructures are more stable than previously assumed $δ$-layers of {\em substitutional} Mn. Contrary to wide-spread belief, the present study demonstrates that {\em interstitial} Mn can be utilized to tune the magnetic properties of Si, and thus provides a new clue for Si-based spintronics materials.

description: When a polymer solution undergoes viscoelastic phase separation, the polymer-rich phase forms a network-like structure even if it is a minor phase. This unique feature is induced by polymer dynamics, which are constrained by the temporal entanglement of polymer chains. The fundamental mechanisms of viscoelastic phase separation have already been elucidated by theory and experiments over the past few decades; however, it is not yet well understood how viscoelastic phase separation occurs in multicomponent polymer solutions. Here, we construct a new viscoelastic phase separation model for ternary polymer solutions that consist of a polymer, solvent, and nonsolvent. Our simulation results reveal that a network-like structure is formed in the ternary bulk system through a phase separation mechanism similar to that observed in binary polymer solutions. A difference in dynamics is also found in that the solvent, whose affinity to the polymer is similar to that to the nonsolvent, moves freely between the polymer-rich and water-rich phases during phase separation. These findings are considered important for understanding the phase separation mechanism of ternary mixtures often used in the manufacturing of polymeric separation membranes.

description: Η καρδιακή ανεπάρκεια αποτελεί αναμφίβολα ένα μείζον κοινωνικό πρόβλημα. Περισσότεροι από τους μισούς ασθενείς που έχουν νοσηλευτεί για καρδιακή ανεπάρκεια θα οδηγηθούν ξανά στο νοσοκομείο σε σύντομο χρονικό διάστημα. Στο πλαίσιο αυτό, διενεργήθηκε η παρούσα μελέτη κοόρτης στην οποία συμπεριλήφθηκαν ασθενείς με καρδιακή ανεπάρκεια που καταγράφηκαν στο τακτικό ιατρείο Καρδιακής Ανεπάρκειας της Α΄ Καρδιολογικής Κλινικής του Πανεπιστημιακού Νοσοκομείου Θεσσαλονίκης ΑΧΕΠΑ για το χρονικό διάστημα μεταξύ Δεκεμβρίου του 2014 και Απριλίου του 2016. Το καταληκτικό σημείο που διερευνήθηκε ήταν ο χρόνος που χρειάστηκε για την επανανοσηλεία λόγω απορρύθμισης της καρδιακής ανεπάρκειας ή το θάνατο των ασθενών με καρδιακή ανεπάρκεια. Πιο συγκεκριμένα, μελετήθηκε η προβλεπτική αξία επιδημιολογικών, κλινικών και παρακλινικών μεταβλητών ως προς την εμφάνιση του καταληκτικού σημείου. Στην κοόρτη συμπεριλήφθηκαν 108 ασθενείς (ηλικία 68.5 (19), 72% άνδρες, 66% ΚΑ με ελαττωμένο ΚΕ). O διάμεσος χρόνος παρακολούθησης τους ήταν 5.5 (8) μήνες και το καταληκτικό σημείο ικανοποιήθηκε για 38 ασθενείς, αριθμός που αντιστοιχεί στο 35%, με τις επαναληπτικές νοσηλείες να φτάνουν το 27%. Μετά την εφαρμογή του πολυπαραγοντικού μοντέλου αναλογικών κινδύνων κατά Cox διαπιστώθηκε ότι η χρόνια νεφρική ανεπάρκεια (eGFR<60 ml/min/m2) και το μέτριο/εκτεταμένο οίδημα αποτελούν ανεξάρτητους προβλεπτικούς δείκτες των επαναληπτικών νοσηλειών ή του θανάτου για τους ασθενείς με καρδιακή ανεπάρκεια (HR: 2.326, CI: 1.173-4.613; HR: 2.248, CI: 1.013-4.991, αντίστοιχα).
description: The purpose of this study was to identify predictors of rehospitalization or death in patients with heart failure. Multiple hospitalizations are extremely common after heart failure diagnosis, reflecting the poor quality of life often experienced by those patients. However, it is difficult to predict rehospitalization due to heart failure exacerbation. As a result, we conducted a single center based cohort study, comprising all consecutive patients who visited the Heart failure department at AXEPA hospital, from December 2014 to April 2016. Demographic, clinical and paraclinical data were evaluated and included in a multivariate Cox regression model to identify predictors of rehospitalization or death. In short, a total of 108 patients (age 68.5 (19), 72% males, 66% HFrEF) were included in the analysis. The median follow-up period was 5.5 (8) months and the rate of hospital readmission due to worsening HF, or death was 35% (30 rehospitalizations; 8 deaths). Finally, chronic kidney disease (eGFR<60 ml/min/m2) and extensive edema were found to be independent predictors of the combined endpoint (HR: 2.326, CI: 1.173-4.613; HR: 2.248, CI: 1.013-4.991, respectively).

description: The second law of thermodynamics dictates that heat simultaneously flows from the hot to cold bath on average. To go beyond this picture, a range of works in the past decade show that, other than the average dynamical heat flux determined by instantaneous thermal bias, a non-trivial flux contribution of intrinsic geometric origin is generally present in temporally driven systems. This additional heat flux provides a free lunch for the pumped heat and could even drive heat against the bias. We review here the emergence and development of this so called ``geometric heat pump'', originating from the topological geometric phase effect, and cover various quantum and classical transport systems with different internal dynamics. The generalization from the adiabatic to the non-adiabatic regime and the application of control theory are also discussed. Then, we briefly discuss the symmetry restriction on the heat pump effect, such as duality, supersymmetry and time-reversal symmetry. Finally, we examine open problems concerning the geometric heat pump process and elucidate their prospective significance in devising thermal machines with high performance.

description: Using recent high-statistics STAR data from Au+Au and Cu+Cu collisions at full RHIC energy I discuss strong and Coulomb-induced final state interaction effects on identical ($π-π$) and non-identical ($π-Ξ$) particle correlations. Analysis of $π-Ξ$ correlations reveals the strong and Coulomb-induced FSI effects allowing for the first time to estimate space extension of $π$ and $Ξ$ sources and average shift between them. Source imaging technique providing clean separation of these effects from effects due to the source function itself is applied to one-dimensional relative momentum correlation function of identical pions. For low momentum pions and/or non-central collisions large departure from a single-Gaussian shape is observed.

description: For decades, researchers have been studying genetic variation and its impact on drug response and efficacy. Despite this, threr is still a lack of information on how common and rare pharmacogenetic (PGx) variants affect medication in the Chiinese population, particularity for newborns. Here, we used high-depth whole genome sequencing (WGS) data of 6,442 nono-related infants from Qingdao, China, to establish a comprehensive PGx database in Han Chinese population, named "QDnewborn Cohort PGx dataset". In total, we identified 593,206 SNPs and InDels from 257 pharmacogenes, of which 49.49% were novel and 91.22% were rare variants (MAF<0.01). Additionally, we investigated therapeutic PGx variations and drug dosage influence in the cohort from individual tp population level regarding 58 drugs from CPIC level A guideline and the latest Chinese National Reimbursement Drug List. Of note, 27 of selected drugs were associated with dosage adjustment and/or ARDs which at least affecting over 10% of newborns, suggesting a potentially clinical impacts of pre-emptive PGx profiling. To our knowledge, this study is the largest by far to systematically explore the genetic diversity of PGx variation in Northern Han Chinese. The web-based database offers a significant resource for future pharmacogenetic genotype analyses, including common, known, and rare functional variants, to develop personalized medication strategies.

description: We propose a novel generic reputation bootstrapping framework for composite services. Multiple reputation-related indicators are considered in a layer-based framework to implicitly reflect the reputation of the component services. The importance of an indicator on the future performance of a component service is learned using a modified Random Forest algorithm. We propose a topology-aware Forest Deep Neural Network (fDNN) to find the correlations between the reputation of a composite service and reputation indicators of component services. The trained fDNN model predicts the reputation of a new composite service with the confidence value. Experimental results with real-world dataset prove the efficiency of the proposed approach.

We describe an experimental implementation of an atomic gradiometer with a noise level below 10 fT/Hz^{1/2}, fractional field sensitivity below 10^{-9}/Hz^{1/2}, and an active measurement volume of about 1.5 cm^3. We show that the fundamental field sensitivity of a scalar magnetometer is determined by the rate of alkali-metal spin-exchange collisions even though the resonance linewidth can be made much smaller than the spin-exchange rate by pumping most atoms into a stretched spin state.

description: The subject of this study is the detection of teenage girls’ portraits in modern adolescent literature, focusing on how the teenage heroines construct their identity. The theoretical part of the paper is consisted of an approximation of the area of literature, its connection with the production of ideology, while highlighting the special dimension of socialization in adolescent literature through the reproduction of dominant ideologies. Then, the term "young- adolescent literature" is clarified and a short history of Greek adolescent literature is presented. In addition, a connection between feminist criticism and literary theory is attempted, as well as a definition of poetic feminist fiction novel. Finally, the term "gender identity" is approached in the light of poststructuralism and adolescence is analyzed as a search stage of identities. In the research part, the method of Discourse Analysis is presented, the underlying assumptions of Logopsychologias and the interpretive repertoire as a methodological analysis tool are analyzed. Afterwards, the analysis follows, in a way which derives from the groupings of the repertoires. Finally, some of the key findings are exposed in the way they map the world of teenage girls and the construction of the female identity in contemporary adolescent fiction novels.

description: This review presents experimental results on the inter-edge-state transport in the quantum Hall effect, mostly obtained in the regime of high imbalance. The application of a special geometry makes it possible to perform I-V spectroscopy between individual edge channels in both the integer and the fractional regime. This makes it possible to study in detail a number of physical effects such as the creation of topological defects in the integer quantum Hall effect and neutral collective modes excitation in fractional regime. The while many of the experimental findings are well explained within established theories of the quantum Hall effects, a number of observations give new insight into the local structure at the sample edge, which can serve as a starting point for further theoretical studies.

Jets and complex magnetic fields are ubiquitous in the solar atmosphere, which suggests the possibility of the kink instability in certain cases. The aim of the paper is to study the kink instability of triangular jets sandwiched between magnetic tubes/slabs and its possible connection to observed properties of the jets in the solar atmosphere. A dispersion equation governing the kink perturbations is obtained through matching of analytical solutions at the jet boundaries. The equation is solved analytically and numerically for different parameters of jets and surrounding plasma. The analytical solution is accompanied by a numerical simulation of fully nonlinear MHD equations for a particular situation of solar type II spicules. MHD triangular jets are unstable to the dynamic kink instability depending on the Alfven Mach number (the ratio of flow to Alfven speeds) and the ratio of internal and external densities. When the jet has the same density as the surrounding plasma, then only super Alfvenic flows are unstable. However, denser jets are unstable also in sub Alfvenic regime. Jets with an angle to the ambient magnetic field have much lower thresholds of instability than field-aligned flows. Growth times of the kink instability are estimated as 6-15 min for type I spicules and 5-60 s for type II spicules matching with their observed life times. Numerical simulation of full nonlinear equations shows that the transverse kink pulse locally destroys the jet in less than a minute in the conditions of type II spicules. Dynamic kink instability may lead to full breakdown of MHD flows and consequently to observed disappearance of spicules in the solar atmosphere.

description: We report a first-principles study of the energetics of hydrogen absorption and desorption (i.e. H-vacancy formation) on pure and Ti-doped sodium alanate (NaAlH4) surfaces. We find that the Ti atom facilitates the dissociation of H2 molecules as well as the adsorption of H atoms. In addition, the dopant makes it energetically more favorable to creat H vacancies by saturating Al dangling bonds. Interestingly, our results show that the Ti dopant brings close in energy all the steps presumably involved in the absorption and desorption of hydrogen, thus facilitating both and enhancing the reaction kinetics of the alanates. We also discuss the possibility of using other light transition metals (Sc, V, and Cr) as dopants.

description: The evolution of Bose-Einstein condensates is usually described by the famous time-dependent Gross-Pitaevskii equation, which assumes all bosons to reside in a single time-dependent orbital. In the present work we address the evolution of fragmented condensates, for which two (or more) orbitals are occupied, and derive a corresponding time-dependent multi-orbital mean-field theory. We call our theory TDMF($n$), where $n$ stands for the number of evolving fragments. Working equations for a general two-body interaction between the bosons are explicitly presented along with an illustrative numerical example.

description: The Clustered Shortest-Path Tree Problem (CluSPT) plays an important role in various types of optimization problems in real-life. Recently, some Multifactorial Evolutionary Algorithm (MFEA) have been introduced to deal with the CluSPT, however these researches still have some shortcomings such as evolution operators only perform on complete graphs, huge resource consumption for finding the solution on large search spaces. To overcome these limitations, this paper describes a MFEA-based approach to solve the CluSPT. The proposed algorithm utilizes Dijkstra's algorithm to construct the spanning trees in clusters while using evolutionary operators for building the spanning tree connecting clusters. This approach takes advantage of both exact and approximate algorithms so it enables the algorithm to function efficiently on complete and sparse graphs alike. Furthermore, evolutionary operators such as individual encoding and decoding methods are also designed with great consideration regarding performance and memory usage. We have included a proof on the repairing method's efficacy in ensuring all solutions are valid. We have conducted tests on various types of Euclidean instances to assess the effectiveness of the proposed algorithm and methods. Experiment results point out the effectiveness of the proposed algorithm existing heuristic algorithms in most of the test cases. The impact of the proposed MFEA was analyzed and a possible influential factor that may be useful for further study was also pointed out.

Women, the household economy and the informal sector in Hanoi
Creators: name: Drummond, Lisa Barbara Welch
Publisher: name: University of British Columbia
Year: 2008

description: This thesis explores the role of women in a transitional economy. Doi moi, the process of 'renovation', is the restructuring of the economy from centrally-planned to market-driven. The consequences of this restructuring is affecting women’s economic roles in the economy and in the household in very specific ways. Vietnamese women have a long history of participation, if not domination, of trading activities. The simultaneous lifting of restrictions against the private sector and mass unemployment resulting from cuts in subsidies to state-owned enterprise has resulted in a blossoming of the informal sector, and a revival of this 'traditional’ occupation for women. This revival has taken place with the tacit, sometimes outright encouragement of the government, which looks to the household to play the economic and social role necessary to replace the shrinking state sector employment and crumbling social services system. This thesis looks specifically at the informal sector in Hanoi, the capital of Vietnam, and issues in the lives of women who participate in it. The thesis describes in general terms the situation of urban women in contemporary Vietnam, reviews some of the major economic developments in Vietnam since reunifcation in 1975, and looks at some issues in urbanization trends in Hanoi which affect and involve the informal sector. The focus of the thesis is a discussion of qualitative research interviews conducted in 1991-92 with women in informal sector activities, which details these activities and the ways in which this type of employment affects women's roles within the household and in society.

description: Bosonic and fermionic particle currents can be introduced in a more unified way, with the cost of introducing a preferred spacetime foliation. Such a unified treatment of bosons and fermions naturally emerges from an analogous superstring current, showing that the preferred spacetime foliation appears only at the level of effective field theory, not at the fundamental superstring level. The existence of the preferred spacetime foliation allows an objective definition of particles associated with quantum field theory in curved spacetime. Such an objective definition of particles makes the Bohmian interpretation of particle quantum mechanics more appealing. The superstring current allows a consistent Bohmian interpretation of superstrings themselves, including a Bohmian description of string creation and destruction in terms of string splitting. The Bohmian equations of motion and the corresponding probabilistic predictions are fully relativistic covariant and do not depend on the preferred foliation.

description: We investigate strongly asymmetric self-assembled nanostructures with one of dimensions reaching hundreds of nanometers. Close to the nanowire-like type of confinement, such objects are sometimes assigned as one-dimensional in nature. Here, we directly observe the spectrum of exciton excited states corresponding to longitudinal quantization. This is based on probing the optical transitions via polarization-resolved microphotoluminescence excitation ($μ$PLE) measurement performed on single nanostructures combined with theoretical calculation of neutral and charged exciton optical properties. We successfully probe absorption-like spectra for individual bright states forming the exciton ground-state fine structure, as well as for the negatively charged exciton. Confronting the calculated spectrum of excitonic absorption with $μ$PLE traces, we identify optical transitions involving states that contain carriers at various excited levels related to the longest dimension. Based on cross-polarized excitation-detection scheme, we show very well conserved spin configuration during orbital relaxation of the exciton from a number of excited states comparable to the quasi-resonant pumping via the optical phonon, and no polarization memory for the trion, as theoretically expected.

description: We study the optical appearance of a thin accretion disk around compact objects within the Einstein-Gauss-Bonnet gravity. Considering static spherically symmetric black holes and naked singularities we search for characteristic signatures which can arise in the observable images due to the modification of general relativity. While the images of the Gauss-Bonnet black holes closely resemble the Schwarzschild black hole, naked singularities possess a distinctive feature. A series of bright rings are formed in the central part of the images with observable radiation $10^3$ times larger than the rest of the flux making them observationally significant. We elucidate the physical mechanism, which causes the appearance of the central rings, showing that the image is determined by the light ring structure of the spacetime. In a certain region of the parametric space the Gauss-Bonnet naked singularities possess a stable and an unstable light ring. In addition the gravitational field becomes repulsive in a certain neighbourhood of the singularity. This combination of features leads to the formation of the central rings implying that the effect is not specific for the Einstein-Gauss-Bonnet gravity but would also appear for any other compact object with the same characteristics of the photon dynamics.

description: In this paper causal geodesic completeness of FLRW cosmological models is analysed in terms of generalised power expansions of the scale factor in coordinate time. The strength of the found singularities is discussed following the usual definitions due to Tipler and Krolak. It is shown that while classical cosmological models are both timelike and lightlike geodesically incomplete, certain observationally alllowed models which have been proposed recently are lightlike geodesically complete.

The role of foliar glucosinolates in host plant resistance of oilseed rape and mustard to the Bertha armyworm and the diamondback moth
Creators: name: McCloskey, Catherine A.
Publisher: name: University of British Columbia
Year: 2008

description: The relationships between host plant glucosinolates and feeding and growth of a polyphagous insect, the Bertha armyworm, Mamestra configurata Walker and field infestation levels of an oligophagous insect, the diamondback moth, Plutella xylostella L. were investigated. M. configurata reared on eight rape and mustard varieties had significantly different final weights by species order Brassica juncea <Sinapis alba < B. napus < B. rapa. In choice tests, B. juncea was least preferred while S. alba was significantly more attractive than rape to neonate larvae. Relative consumption and growth rates of fourth in star larvae were also reduced on B. juncea foliage. Neonate choice and fourth in star growth rates were negatively correlated to concentrations of isothiocyanate-releasing glucosinolates. In feeding tests with pure compounds in meridic diets, sinigrin and its metabolite, allyl isothiocyanate inhibited growth in a dose-dependent manner. No effects were observed with indole-3-carbinol, the metabolite of 3-indolylmethyl glucosinolate. Foliar isothiocyanate-releasing glucosinolates may provide some protection against polyphagous insects. Plant growth stage differences in the relative resistance of brassicaceous host plants were investigated by feeding B. juncea (relatively resistant) or B. rapa cv. Tobin (Canola) (susceptible) foliage of three plant growth stages (2-4) to M. configurata. Relative consumption rates did not differ significantly between the plant species. However, with B. rapa, relative consumption rate increased with advancing plant growth stage. Relative growth rates on B. juncea foliage were significantly lower than on B. rapa. With B. juncea, relative growth rate decreased with plant growth stage. Concentrations of isothiocyanate- and thiocyanate-releasing glucosinolatescor responded to the trends observed in the nutritional indices, while levels of total phenols and catechols appeared unimportant. Analyses of total nitrogen in field-collected plants showed a serial reduction with advancing growth stage. The influence of glucosinolate profile on infestation by P.xylostella was investigated using field plots of six rape and mustard varieties. S. alba plots supported larger populations than the other plant species in the study. Parasitism rates by Diadegma insularis (Hymenoptera: Ichneumonidae) were not significantly different between plant species on foliar samples. On flower head samples, larvae on B. juncea were parasitised the most, whereas larvae on S. alba were parasitised the least. The glucosinolate profile of the host plant may be more important to D. insularis than to P.xylostella.
