Protecting an optical qubit against photon loss

Subjects: subject: Quantum Physics (quant-ph)

description: We consider quantum error-correction codes for multimode bosonic systems, such as optical fields, that are affected by amplitude damping. Such a process is a generalization of an erasure channel. We demonstrate that the most accessible method of transforming optical systems with the help of passive linear networks has limited usefulness in preparing and manipulating such codes. These limitations stem directly from the recoverability condition for one-photon loss. We introduce a three-photon code protecting against the first order of amplitude damping, i.e. a single photon loss, and discuss its preparation using linear optics with single-photon sources and conditional detection. Quantum state and process tomography in the code subspace can be implemented using passive linear optics and photon counting. An experimental proof-of-principle demonstration of elements of the proposed quantum error correction scheme for a one-photon erasure lies well within present technological capabilites.

description: Products containing nanomaterials (NMs) (size < 100 nanometres) are rapidly entering the market, however little is known about inhalation exposures to NMs from their use. Here, we analysed representative consumer spray products available in the UK that claim (or are expected) to contain NMs, to assess potential NM exposure levels during use. In the absence of a UK-focused product inventory, we searched “The Nanodatabase” (nanodb.dk), which listed 269 (out of 3001) products for which inhalation was identified as an exposure pathway. None were available over-the-counter at large stores, but 40 were available on “.co.uk” websites (mainly Amazon). We obtained a representative sample (based on product type and claimed content e.g. silver, silica, gold) and found that 12 out of 16 products contained detectable NMs. We used a multi-method approach to characterise the NMs; inductively-coupled plasma mass spectrometry (ICP-MS), ultraviolet-visible spectroscopy and energy-dispersive x-ray spectroscopy to assess NM composition, and dynamic light scattering, nanoparticle tracking analysis, transmission electron microscopy and single particle ICP-MS to determine particle size and shape. The sizes of the airborne particles/droplets produced by spraying a sub-set (6) of these products were measured using aerodynamic and mobility particle sizers, demonstrating the presence of inhalable aerosols. Whilst 5 out of 6 products clearly contained NMs, only 3 produced aerosols in the nano-size range, suggesting that other constituents (e.g. solvent, fragrance) make up the bulk of the aerosol mass. Using the data generated, quantities of NMs inhaled when using these products can be estimated, which is important for appropriate risk characterisation.
GRBs spectral correlations and their cosmological use

description: The correlations involving the long-GRB prompt emission energy represent a new key to understand the GRB physics. These correlations have been proved to be the tool which makes long-GRBs a new class of standard candles. Gamma Ray Bursts, being very powerful cosmological sources detected in the hard X-ray band, represent a new tool to investigate the Universe in a redshift range which is complementary to that covered by other cosmological probes (SNIa and CMB). A review of the Ep-Eiso, Ep-Egamma, Ep-Eiso-tjet, Ep-Liso-T0.45 correlations is presented. Open issues related to these correlations (e.g. presence of outliers and selection effects) and to their use for cosmographic purposes (e.g. dependence on model assumptions) are discussed. Finally, the relevance of thermal components in GRB spectra is discussed in the light of some of the models recently proposed for the interpretation of the spectral-energy correlations.

description: We present an advanced and novel control method to enable actuated Spring Loaded Inverted Pendulum model to walk over rough and challenging terrains. The high-level philosophy is the decoupling of the controls of the vertical and horizontal states. The vertical state is controlled via Backstepping-Barrier Function (BBF) based quadratic programs: a combination of control Lyapunov backstepping and control barrier function, both of which provide inequality constraints on the inputs. The horizontal state is stabilized via Hybrid-Linear Inverted Pendulum (H-LIP) based stepping, which has a closed-form formulation. Therefore, the implementation is computationally-efficient. We evaluate our method in simulation, which demonstrates the aSLIP walking over various terrains, including slopes, stairs, and general rough terrains with uncertainties.

The possibility to achieve b-τunification is studied taking into account all relevant effects. In addition, we show how to establish an upper bound on the ultraviolet cutoff Λof the theory which is compatible with the Yukawa couplings at the grand unified scale and proton decay. We find Λ\simeq 10^{17} GeV, to be considered a conservative upper bound on the cutoff. We also provide up-to-date values of all the fermions masses at the electroweak scale.

The four Mephisto waltzes of Franz Liszt
Creators: name: Barrington, Barrie M.
Publisher: name: University of British Columbia
Year: 2008

description: The four Mephisto Waltzes of Franz Liszt constitute the focus of the present paper. Aside from the fascination they hold as individual works, they form an intriguing group related by title and heritage yet made distinct by important structural differences. Also, the separation of more than 20 years between the completion of the first and the last means that as a group they illustrate well the changes of style and concerns in Liszt’s composing. In this paper, the four works are discussed in a manner that reflects a shift in their dramatic source. The first two waltzes are closely tied to the poem Faust by Nikolaus Lenau and derive most of their drama from that extra musical link. The latter two pieces, however, exhibit fewer connections to the poem but contain compelling tonal and structural features. The first two chapters discuss the First and Second Mephisto Waltzes respectively with an emphasis on those aspects that are most closely associated with Lenau's Faust. In addition, certain passages that are not necessarily tied to the poem but are interesting in themselves are discussed. An example of this is the coda of the Second Mephisto Waltz and its effect on the piece's overall tonality. The third chapter discusses those few elements of the Third and Fourth Mephisto Waltzes that can be seen as stemming from Lenau's poem, while the final two chapters are made up of tonal and structural analyses of these latter two waltzes. The Third Mephisto Waltz, in particular, is treated to a more intense analysis since it is the most problematic of the group. In this piece, the overall tonic is unclear as two different, yet related, keys struggle to dominate, with neither coming to a clear and decisive victory. F-sharp major and D-sharp minor are supported in turn throughout the work and can be seen to coexist at times when the piece is viewed in its background. The Fourth Mephisto Waltz, although tonally more clear, contains a dramatic game of frustrated expectations and then unexpected fulfillment as the tonic, F-sharp, is strongly implied twice and only later is attained with little preparation. In order to come to terms with some of the problems posed by these works, I have used a modified form of Schenkerian analysis. Departures from, or additions to standard techniques are mentioned within the appropriate chapters. Since the four Mephisto Waltzes (especially the latter two) have not been exhaustively analysed, it is hoped that this study makes some contribution to the field of Liszt research.
To Trust or to Think: Cognitive Forcing Functions Can Reduce Overreliance on AI in AI-assisted Decision-making

description: People supported by AI-powered decision support tools frequently overrely on the AI: they accept an AI's suggestion even when that suggestion is wrong. Adding explanations to the AI decisions does not appear to reduce the overreliance and some studies suggest that it might even increase it. Informed by the dual-process theory of cognition, we posit that people rarely engage analytically with each individual AI recommendation and explanation, and instead develop general heuristics about whether and when to follow the AI suggestions. Building on prior research on medical decision-making, we designed three cognitive forcing interventions to compel people to engage more thoughtfully with the AI-generated explanations. We conducted an experiment (N=199), in which we compared our three cognitive forcing designs to two simple explainable AI approaches and to a no-AI baseline. The results demonstrate that cognitive forcing significantly reduced overreliance compared to the simple explainable AI approaches. However, there was a trade-off: people assigned the least favorable subjective ratings to the designs that reduced the overreliance the most. To audit our work for intervention-generated inequalities, we investigated whether our interventions benefited equally people with different levels of Need for Cognition (i.e., motivation to engage in effortful mental activities). Our results show that, on average, cognitive forcing interventions benefited participants higher in Need for Cognition more. Our research suggests that human cognitive motivation moderates the effectiveness of explainable AI solutions.

description: We consider the excitation dynamics of the two-photon \sts transition in a beam of atomic hydrogen by 243 nm laser radiation. Specifically, we study the impact of ionization damping on the transition line shape, caused by the possibility of ionization of the 2S level by the same laser field. Using a Monte-Carlo simulation, we calculate the line shape of the \sts transition for the experimental geometry used in the two latest absolute frequency measurements (M. Niering {\it et al.}, PRL 84, 5496 (2000) and M. Fischer {\it et al.}, PRL 92, 230802 (2004)). The calculated line shift and line width are in excellent agreement with the experimentally observed values. From this comparison we can verify the values of the dynamic Stark shift coefficient for the \sts transition for the first time on a level of 15%. We show that the ionization modifies the velocity distribution of the metastable atoms, the line shape of the \sts transition, and has an influence on the derivation of its absolute frequency.

description: The project aims to build a fully-fledged Social Sciences and Humanities Open Cloud (SSHOC) where users of Social Sciences and Humanities (SSH) data are provided with data, tools and training materials. SSHOC plays a key role in the realization of Europe’s Open Science agenda and the European Open Science Cloud (EOSC). This community engagement strategy outlines how the project will engage with the SSHOC community coherently and efficiently, thereby fostering community engagement, developing a data-sharing culture that follows the FAIR principles, and giving user communities knowledge, skills and expertise so that they can use and contribute to SSHOC resources. The strategy also describes the stakeholder categories identified in the SSHOC Overall Communication and OutreachPlan, and follows a stakeholder landscape analysis performed by project partners. It explains why the SSHOC project should engage with these stakeholders, outlines key messages and value propositions for each group, and shares the most effective channels and approaches to be used. Collaboration between project Work Packages (WPs) and coordination of timeline of engagement activities, will create a storyline of engagement for each group. This is critical in order to gain a certain level of commitment. It is important to note that project partners already represent a big part of the SSH community. This strategy, therefore, builds on existing networks, channels and tools. Furthermore, collaboration with other EOSC-relevant projects will be at the core of activities. The strategy is complemented by a set of KPIs based on identified needs and assigned activities to project partners, as per the Grant Agreement. Provisions for possible gaps and risks are also addressed. This Community Engagement Strategy is in line with the activities of the SSHOC Overall Communication and Outreach Plan, keeps and intentionally flexible timeline, in order to be able to adapt to current EOSC developments and will be complemented by the training activities of a sound Building Expertise Strategy to be delivered in December 2019.

description: The core structure of multiply quantized vortices is theoretically investigated in fermionic superfluid near Feshbach resonance. Under population imbalance in two hyperfine spin states, the vortex core is filled in by the ``paramagnetic moment''. Here, we find the spatial oscillation of the magnetization inside the core sensitively due to the topological structure of the pairing field, in the range from the weak coupling regime to the unitary limit. This magnetization inside the giant core reveals the winding number of the vortex and directly results from the low-lying quasiparticle states bound inside the core. It is therefore proposed that the density profile experiment using phase contrast imaging can provide the spectroscopy of novel core level structures in giant vortices. To help the understanding on these outcomes, we also derive the analytic solution for the low-lying quasiparticle states inside the core of a multiply quantized vortex.

description: Image matting is an ill-posed problem that aims to estimate the opacity of foreground pixels in an image. However, most existing deep learning-based methods still suffer from the coarse-grained details. In general, these algorithms are incapable of felicitously distinguishing the degree of exploration between deterministic domains (certain FG and BG pixels) and undetermined domains (uncertain in-between pixels), or inevitably lose information in the continuous sampling process, leading to a sub-optimal result. In this paper, we propose a novel network named Prior-Induced Information Alignment Matting Network (PIIAMatting), which can efficiently model the distinction of pixel-wise response maps and the correlation of layer-wise feature maps. It mainly consists of a Dynamic Gaussian Modulation mechanism (DGM) and an Information Alignment strategy (IA). Specifically, the DGM can dynamically acquire a pixel-wise domain response map learned from the prior distribution. The response map can present the relationship between the opacity variation and the convergence process during training. On the other hand, the IA comprises an Information Match Module (IMM) and an Information Aggregation Module (IAM), jointly scheduled to match and aggregate the adjacent layer-wise features adaptively. Besides, we also develop a Multi-Scale Refinement (MSR) module to integrate multi-scale receptive field information at the refinement stage to recover the fluctuating appearance details. Extensive quantitative and qualitative evaluations demonstrate that the proposed PIIAMatting performs favourably against state-of-the-art image matting methods on the Alphamatting.com, Composition-1K and Distinctions-646 dataset.

description: Given a graph $G=(V,E)$, the $b$-coloring problem consists in attributing a color to every vertex in $V$ such that adjacent vertices receive different colors, every color has a $b$-vertex, and the number of colors is maximized. A $b$-vertex is a vertex adjacent to vertices colored with all used colors but its own. The $b$-coloring problem is known to be NP-Hard and its optimal solution determines the $b$-chromatic number of $G$, denoted $χ_b(G)$. This paper presents an integer programming formulation and a very effective multi-greedy randomized heuristic which can be used in a multi-start metaheuristic. In addition, a matheuristic approach is proposed combining the multi-start multi-greedy randomized metaheuristic with a MIP (mixed integer programming) based local search procedure using the integer programming formulation. Computational experiments establish the proposed multi-start metaheuristic as very effective in generating high quality solutions, along with the matheuristic approach successfully improving several of those results. Moreover, the computational results show that the multi-start metaheuristic outperforms a state-of-the-art hybrid evolutionary metaheuristic for a subset of the large instances which were previously considered in the literature. An additional contribution of this work is the proposal of a benchmark instance set, which consists of newly generated instances as well as others available in the literature for classical graph problems, with the aim of standardizing computational comparisons of approaches for the $b$-coloring problem in future works.

description: Systematic surveys of astronomical objects often lead to discoveries, but always provide invaluable information for statistical studies of well-defined samples. They also promote follow-up investigations of individual objects or classes. Surveys using a yet unexplored observing wavelength, a novel technique or a new instrument are of special importance. Significantly improved observing parameters (e.g. sensitivity, angular resolution, monitoring capability) provide new insight into the morphological and physical properties of the objects studied. I give a brief overview of the important Very Long Baseline Interferometry (VLBI) imaging surveys conducted in the past. A list of surveys guides us through the developments up until the present days. I also attempt to show directions for the near future.

description: For planning further activities in WP6 - Fostering Communities, Empowering Users, & Building Expertise as well as input for the development of the SSH Open Marketplace in WP7- Creating the SSH Open Marketplace it is indispensable to survey the current landscape of existing training materials in the SSH cluster as well as in the broader context of EOSC. Numerous similar activities have been performed in various recent EOSC- and FAIR- related projects and these have served as partial input while compiling this inventory. Around 30 sources of training material of various kinds and scopes have been gathered initially. These were analysed along with a number of dimensions, like intended audience, relevant discipline, topics covered, extent, status etc. Additionally, for most of the sources, a few individual training material items were picked and described in further detail. All this information has been collected through a dedicated Drupal-based application. The collected information is not exhausting, but it should provide a sufficient probe into the training materials landscape to inform further actions. Particularly it reveals the following findings: There seems to be a host of material on Research Data Management and application of FAIR principles, as well as on basic scripting skills for Data Science, i.e. working with the shell, programming with Python/R, for purposes of automatically processing data. We can distinguish four types of training materials: e-learning courses, carpentry-style, blog-style, static (slides, videos, PDFs) There are numerous sources that seem to be abandoned or in danger of becoming obsolete. There is little to none harmonisation with respect to metadata about the training material. This information is seldom available in structured and automatically harvestable form. The findings imply the following recommendations for further work in WP6 and WP7: Perform a gap analysis on the topic coverage combined with the set of topics which could be provided by the individual WPs of the project Reserve sufficient capacities for the manual curation of existing sources, defining metadata and communicating with the providers. Start as soon as possible.

Low level Tc1 transposition and Tc1-induced mutations in dpy-5
Creators: name: Babity, Joseph M.
Publisher: name: University of British Columbia
Year: 2008

description: The transposable element Tcl is the most thoroughly studied transposon in the nematode Caenorhabditiselegans. In this thesis I have examined Tcl transposition in the Bristol strain of C. elegans and analyzed Tcl-induced mutations in the dpy-5 gene of chromosome I. In the Bristol strain of C. elegans, germline Tcl transposition has been undetectable; however, Bristol isolates were identified in which low-level Tcl transposition was observed. In the gene identified as dpy-5, one of many genes that affect overall worm morphology in C. elegans, Tcl-inducedmutations were examined and used to clone the dpy-5 gene and a second gene in the dpy-5 region. A novel Tcl element from a Bristol isolate was cloned and the genomic insertion site was analyzed. The sequence of the insertion site was found to be similar to the consensus sequence for transposition insertion indicating that germline Tcl transposition had occurred. Further analysis identified a derivative Bristol strain in which a high level of germline Tcl transposition was observed. Six Tcl-induced alleles of dpy-5 were studied. From one of these alleles a novel 2.7 kilobase pair Tcl-hybridizing EcoRI fragment was isolated and used as a tag in cloning the dpy-5 gene. Examination of Tcl-induced mutations of dpy-5 and wild type revertants revealed that the mutation was the result of Tcl transposition into a1.1 kilobase pair genomic EcoRI fragment. The dpy-5 gene was sequenced and shown to encode a 254 amino acid protein. The gene has no known homologues or protein patterns; however, a potential secretion signal peptide has been identified. Northern analysis indicates that the gene is developmentally expressed, correlating well with the onset of the Dpy-5 phenotype. Analysis of DNA sequences upstream from the dpy-5 gene reveals the presence of a neighbouring gene with homology to casein kinase I.

description: M-theory preons -- solutions of eleven-dimensional supergravity preserving 31 supersymmetries -- have recently been shown to be locally maximally supersymmetric. This implies that if preons exist they are quotients of maximally supersymmetric solutions. In this paper we show that no such quotients exist. This is achieved by reducing the problem to quotients by cyclic groups in the image of the exponential map, for which there already exists a partial classification, which is completed in the present paper.

description: We investigate the cause of exchange anisotropy in a family of copper-based, quasi-two-dimensional materials with very similar geometries. This family differs mainly in the inter-layer separation, but have very different magnetic interactions even within the basal plane. We use density functional theory and Wannier functions to parameterize two complimentary tight-binding models and show that the superexchange between the Cu(II) ions is dominated by a through-space interaction between hybrid Cu-pyrazine orbitals centered on the copper atoms. We find no correlations between the strength of this exchange interaction with homologous geometric features across the compounds, such as Cu and pyrazine bond lengths and orientations of nearby counter-ions. We find that the pyrazine tilt angles do not affect the Cu-pyrazine-Cu exchange because the lowest unoccupied molecular orbital on the pyrazine is at a very high energy (relative to the frontier orbitals, which are Cu-based). We conclude that the anisotropy of magnetic interactions within this family of materials is largely unpredictable before the crystal structure is firmly established -- it is due to non-homologous geometric features such as the inter-layer organic ligands previously thought to be benign.

Στην συνέχεια, στο δίκτυο αυτό εφαρμόστηκε ο αλγόριθμος walktrap για την εύρεση των ομάδων/ clusters μέσα στις οποίες οι συνδέσεις μεταξύ των χωρών είναι εντονότερες. Ο αλγόριθμος χώρισε τις υπάρχουσες συνδέσεις σε πέντε ξεχωριστές ομάδες.

The research of the paper was based on the econometric method of Granger causality. This method is suitable for the examination of the transmitted information from the past to the present in linear systems. Statistically significant connections (pairs) of countries, that were found, were used to generate a directed effect network linking the countries that produce effect with the countries receiving this influence. Then, Walktrap algorithm was applied in the network in order to find the groups / clusters in which the connections between countries are more pronounced. The algorithm grouped the existing connections in five separate groups. These final groups witness the failure of the EU to operate under a common price regime and broader mutual response to each transmitted information. At the same time, the results reveal a strong correlation between the interaction of price formation and the natural geographical distance between countries.

description: This deliverable describes the first release of the SSHOC Training Toolkit which was launched on April 20th 1
 2020 . The Toolkit consists of an inventory of various learning and training materials that trainers in the Social Sciences and Humanities (SSH) can use to develop and improve their own training activities. The Toolkit at the time of the launch listed over 70 materials from 41 different sources in various formats, such as slides, modules, videos, games and other items. Materials cover a range of topics including Research Data Management, FAIR data, text encoding, Open Science, and quantitative analysis, as well as didactics for better development and implementation of training activities Information about these train-the-trainer materials was collected and are displayed using a dedicated drupal- based application that was already utilized for the inventory of existing training materials described in D6.7 Inventory of existing learning materials (Ďurčo, Illmayer & Barbot, 2019). The Toolkit will be further developed in collaboration with the SSHOC Training Community and presented and evaluated during the SSHOC Train-the-Trainer Bootcamps. Note on the terminology While the original title of the toolkit mentioned in the grant proposal and agreement was “SSHOC Train-the- Trainer Toolkit” rather than “SSHOC Training Toolkit”, the task team has decided to adapt the name to “SSHOC Training Toolkit” as it more accurately describes the content of the toolkit and its use. The Toolkit is directed at SSH trainers, but next to train-the-trainer materials, the toolkit also contains information on other learning and training materials available for the SSH community. The development of the toolkit was based on an already performed inventory for SSH learning materials (D6.7) and it was felt that the collected information was of use to SSH trainers and the SSH community as well. Therefore, it was decided to adjust the name of the toolkit to better reflect its content and potential use. The term “SSHOC Training Toolkit” is hence used in the deliverable names and in the SSHOC online communication.

description: We derive critical noise levels for Gallager codes on asymmetric channels as a function of the input bias and the temperature. Using a statistical mechanics approach we study the space of codewords and the entropy in the various decoding regimes. We further discuss the relation of the convergence of the message passing algorithm with the endogeny property and complexity, characterizing solutions of recursive equations of distributions for cavity fields.

description: The Galactic black hole candidate (BHC) 4U~1630-472 has gone through several outbursts (13 to be particular) in the last two and a half decades starting from the RXTE era till date. Like the outbursts of other transient BHCs, the outbursts of this source show variations in duration, peak numbers, highest peak flux, etc. However, unlike any other soft X-ray transients, this source showed outbursts of two types, such as normal and super. The normal outbursts of duration $\sim 100-200$~days are observed quasi periodically at an average recurrence/quiescence period of $\sim 500$~days. The super outbursts of duration $\sim 1.5-2.5$~years contain one or more normal outbursts other than one mega outburst. We make an effort to separate flux contribution of the normal and the mega outbursts from the super outbursts, and tried to understand the nature of evolution of both types (normal and mega) of outbursts, based on the quiescent period prior to the outbursts. Archival data of RXTE/ASM from January 1996 to June 2011, and MAXI/GSC from August 2009 to July 2020 are used for our study. A possible linear relation between the quiescent and outburstsing periods for both types of outbursts are observed. This makes the BHC a special source, and it may contain two companion binaries. Two companions might be responsible for two types of outbursts.

A near-infrared shock wave in the 2006 outburst of recurrent nova RS Ophiuchi

description: Near-infrared spectra are presented for the recent 2006 outburst of the recurrent nova RS Ophiuchi (RS Oph).We report the rare detection of an infrared shock wave as the nova ejecta plows into the pre-existing wind of the secondary in the RS Oph system consisting of a white dwarf (WD) primary and a red giant secondary. The evolution of the shock is traced through a free expansion stage to a decelerative phase. The behavior of the shock velocity with time is found to be broadly consistent with current shock models. The present observations also imply that the WD in the RS Oph system has a high mass indicating that it could be a potential SNIa candidate. We also discuss the results from a recent study showing that the near-IR continuum from the recent RS Oph eruption does not originate in an expanding fireball. However, the present work shows that the IR line emission does have an origin in an expanding shock wave.

description: In recent work we have shown that a black hole stacked on a brane escapes once it acquires a recoil velocity. This result was obtained in the {\it probe-brane} approximation, {\it i.e.}, when the tension of the brane is negligibly small. Therefore, it is not clear whether the effect of the brane tension may prevent the black hole from escaping for small recoil velocities. The question is whether a critical escape velocity exists. Here, we analyze this problem by studying the interaction between a Dirac-Nambu-Goto brane and a black hole assuming adiabatic (quasi-static) evolution. By describing the brane in a fixed black hole spacetime, which restricts our conclusions to lowest order effects in the tension, we find that the critical escape velocity does not exist for co-dimension one branes, while it does for higher co-dimension branes.

description: Σκοπός της μεταπτυχιακής μου εργασίας είναι η διερεύνηση της ιδεολογίας και πολιτικής πράξης του Gheorghe Gheorghiu-Dej (Γκεόργκε Γκεοργκίου-Ντεζ), του πρώτου ηγέτη της Λαϊκής Δημοκρατίας της Ρουμανίας, κατά την περίοδο της παραμονής του στην εξουσία (1945-1965). Στο Πρώτο Κεφάλαιο ασχολήθηκα με τις πολιτικές εξελίξεις στη Ρουμανία την περίοδο 1930-1944. Στο Δεύτερο Κεφάλαιο, μετά από μία σύντομη αναφορά στην ιστορία του Ρουμανικού Κομμουνιστικού Κόμματος και την πολιτική δράση του Γκεοργκίου-Ντεζ την περίοδο1930-1944, περιγράφεται η άνοδος του Ρουμανικού Κομμουνιστικού Κόμματος στην εξουσία και η έναρξη της σοσιαλιστικής οικοδόμησης στη Ρουμανία κατά την περίοδο 1948-1958. Περιγράφεται ακόμα η εσωκομματική επικράτηση του Γκεοργκίου-Ντεζ, καθώς και οι σχέσεις του Ρουμάνου ηγέτη με τη Σοβιετική Ένωση. Τέλος, στο Τρίτο Κεφάλαιο, περιγράφεται η τελευταία περίοδος ομαλότητας μεταξύ της Λαϊκής Δημοκρατίας της Ρουμανίας και της Σοβιετικής Ένωσης (1958-1963), η ρήξη των δύο χωρών και τα αίτια της, καθώς και η εξέλιξή της (1963-1965). Τέλος, αναλύεται η επονομαζόμενη "Διακήρυξη της Ανεξαρτησίας", ένα πολιτικό μανιφέστο που εσωκλείει την ιδεολογία και πολιτική πράξη του Γκεοργκίου-Ντεζ λίγο πριν τον θάνατό του, το 1965.
description: The aim of my postgraduate paper is to research the ideology and political action of Gheorghe Gheorghiu-Dej, first leader of People's Republic of Romania, during the period he remained in power (1945-1965). First Chapter speaks about the political development in Romania from 1930 until 1944. Second Chapter, after a short reference in the history of Romanian Communist Party and in action of Gheorghiu-Dej during the period 1930-1944, describes the rise of Romanian Communist Party of Romania to power and the launch of socialistic structure, from 1948 until 1958. Furthermore, describes the interparty dominance of Gheorghiu-Dej and the relations of Romanian leader with Soviet Union. Finally, Third Chapter speaks for the last period of normality between the People's Republic of Romania and the Soviet Union (1958-1963), the rupture between them and its origins, as well as its development (1963-1965). Moreover, analyzes the so-called "Declaration of Independence", a political manifest that encloses the ideology and political action of Gheorghiu-Dej, right before his death, in 1965.

description: (Abridged) We study the two-point correlation function of a uniformly selected sample of 4,426 luminous optical quasars with redshift $2.9 \le z\le 5.4$ selected over 4041 deg$^2$ from the Fifth Data Release of the Sloan Digital Sky Survey. For a real-space correlation function of the form $ξ(r)=(r/r_0)^{-γ}$, the fitted parameters in comoving coordinates are $r_0 = 15.2 \pm 2.7 h^{-1}$ Mpc and $γ= 2.0 \pm 0.3$, over a scale range $4\le r_p\le 150 h^{-1}$ Mpc. Thus high-redshift quasars are appreciably more strongly clustered than their $z \approx 1.5$ counterparts, which have a comoving clustering length $r_0 \approx 6.5 h^{-1}$ Mpc. Dividing our sample into two redshift bins: $2.9\le z\le 3.5$ and $z\ge 3.5$, and assuming a power-law index $γ=2.0$, we find a correlation length of $r_0 = 16.9 \pm 1.7 h^{-1}$ Mpc for the former, and $r_0 = 24.3 \pm 2.4 h^{-1}$ Mpc for the latter. Following Martini & Weinberg, we relate the clustering strength and quasar number density to the quasar lifetimes and duty cycle. Using the Sheth & Tormen halo mass function, the quasar lifetime is estimated to lie in the range $4\sim 50$ Myr for quasars with $2.9\le z\le 3.5$; and $30\sim 600$ Myr for quasars with $z\ge 3.5$. The corresponding duty cycles are $0.004\sim 0.05$ for the lower redshift bin and $0.03\sim 0.6$ for the higher redshift bin. The minimum mass of halos in which these quasars reside is $2-3\times 10^{12}\ h^{-1}M_\odot$ for quasars with $2.9\le z\le 3.5$ and $4-6\times 10^{12}\ h^{-1}M_\odot$ for quasars with $z\ge 3.5$.
