description: The capability of the Terrestrial Planet Finder Interferometer (TPF-I) for planetary signal extraction, including both detection and spectral characterization, can be optimized by taking proper account of instrumental characteristics and astrophysical prior information. We have developed the Point Process Algorithm (PPA), a Bayesian technique for extracting planetary signals using the sine-chopped outputs of a dual nulling interferometer. It is so-called because it represents the system being observed as a set of points in a suitably-defined state space, thus providing a natural way of incorporating our prior knowledge of the compact nature of the targets of interest. It can also incorporate the spatial covariance of the exozodi as prior information which could help mitigate against false detections. Data at multiple wavelengths are used simultaneously, taking into account possible spectral variations of the planetary signals. Input parameters include the RMS measurement noise and the a priori probability of the presence of a planet. The output can be represented as an image of the intensity distribution on the sky, optimized for the detection of point sources. Previous approaches by others to the problem of planet detection for TPF-I have relied on the potentially non-robust identification of peaks in a "dirty" image, usually a correlation map. Tests with synthetic data suggest that the PPA provides greater sensitivity to faint sources than does the standard approach (correlation map + CLEAN), and will be a useful tool for optimizing the design of TPF-I.

The Arecibo Legacy Fast ALFA Survey: IV. Strategies for Signal Identification and Survey Catalog Reliability
Creators: name: Saintonge, Amelie
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present a signal extraction utility written for the purposes of the Arecibo Legacy Fast ALFA survey (ALFALFA). This survey, when completed, will have covered 7000 square degrees of the high galactic latitude sky and should detect over 20,000 extragalactic objects. It is the most sensitive blind HI survey to date. The large size of the survey justifies in itself the need for an automated way of identifying signals in the data set. The matched-filtering signal extractor proposed is based on convolutions in the Fourier domain of templates of varying widths with each spectrum. The chosen templates are built from a simple combination of Hermite functions to mimic the shape of typical galactic HI profiles of varying widths. The main advantages of this matched-filtering approach are a sensitivity to the total flux of the signals (and not only to peak flux), robustness against instabilities and short computing times. The details of the algorithm are given here, as well as results of simulations that assess the reliability and completeness of the process.

description: We present radio observations of the source G332.5-5.6, a candidate supernova remnant (SNR). Observations have been performed with the Australia Telescope Compact Array (ATCA) at two frequencies, at 1.4 and 2.4 GHz. Our results confirm that G332.5-5.6 is an SNR, with a spectral index equal to -0.7 +/- 0.2 for the whole source and an average fractional polarization of ~35% at 2.4 GHz. The central component is coincident with extended X-ray emission and the distance to the SNR is estimated to be ~3.4 kpc. Based on its radio and X-ray morphology, this SNR should be classified as a composite, and we suggest that it belongs to a trident-shaped subclass like G291.0-0.1.

description: The aim of the present thesis was the iconographic and theological approach of the most popular imaginary animals in Byzantine art. At the beginning we examined the transition from the Greek-roman to the christian art and we discussed the characteristics of the ancient Greek tradition, that survived until the late byzantine period. Furthermore we presented the most important of the imaginary animals, referencing the Holy Bible and the Patrologia, described their image and their symbolism. At the second part of the thesis we presented the most important monuments from the Early until the Late Byzantine period.

description: Systematic measurements of auto- and cross-correlations of photons emitted from individual CdTe/ZnTe quantum dots under pulsed excitation were used to elucidate non-resonant excitation mechanisms in this self-assembled system. Memory effects extending over a few excitation pulses have been detected in agreement with previous reports and quantitatively described by a rate equation model, fitting a complete set of correlation and PL intensity results. The important role of single carrier trapping in the quantum dot was established. An explanation was suggested for the unusually wide antibunching dip observed previously in X-X autocorrelation experiments on quantum dots under cw excitation.

description: Based on an estimate of the knot entropy of a worm-like chain we predict that the interplay of bending energy and confinement entropy will result in a compact metastable configuration of the knot that will diffuse, without spreading, along the contour of the semi-flexible polymer until it reaches one of the chain ends. Our estimate of the size of the knot as a function of its topological invariant (ideal aspect ratio) agrees with recent experimental results of knotted dsDNA. Further experimental tests of our ideas are proposed.

A Singularity Problem with f(R) Dark Energy

description: In this paper, I point out that there is a curvature singularity problem appearing on non-linear level that generally plagues f(R) models that modify Einstein gravity in the infrared. It is caused by the fact that for the effective scalar degree of freedom, the curvature singularity is at a finite field value and energy level, and can be easily accessed by the field dynamics in the presence of matter. This problem is invisible in linearized analysis, except for the tell-tale growing oscillatory modes it causes. In view of this, viability of many f(R) models in current literature will have to be re-evaluated.

description: We present a comparative full-potential study of generalized Kohn-Sham schemes (gKS) with explicit focus on their suitability as starting point for the solution of the quasiparticle equation. We compare $G_0W_0$ quasiparticle band structures calculated upon LDA, sX, HSE03, PBE0, and HF functionals for exchange and correlation (XC) for Si, InN and ZnO. Furthermore, the HSE03 functional is studied and compared to the GGA for 15 non-metallic materials for its use as a starting point in the calculation of quasiparticle excitation energies. For this case, also the effects of selfconsistency in the $GW$ self-energy are analysed. It is shown that the use of a gKS scheme as a starting point for a perturbative QP correction can improve upon the deficiencies found for LDA or GGA staring points for compounds with shallow $d$ bands. For these solids, the order of the valence and conduction bands is often inverted using local or semi-local approximations for XC, which makes perturbative $G_0W_0$ calculations unreliable. The use of a gKS starting point allows for the calculation of fairly accurate band gaps even in these difficult cases, and generally single-shot $G_0W_0$ calculations following calculations using the HSE03 functional are very close to experiment.

description: In the context of loop quantum gravity, we construct the phase-space of isolated horizons with genus greater than 0. Within the loop quantum gravity framework, these horizons are described by genus g surfaces with N punctures and the dimension of the corresponding phase-space is calculated including the genus cycles as degrees of freedom. From this, the black hole entropy can be calculated by counting the microstates which correspond to a black hole of fixed area. We find that the leading term agrees with the A/4 law and that the sub-leading contribution is modified by the genus cycles.

Electrostatics of Edge States of Quantum Hall Systems with Constrictions: Metal--Insulator Transition Tuned by External Gates

description: The nature of a metal--insulator transition tuned by external gates in quantum Hall (QH) systems with point constrictions at integer bulk filling, as reported in recent experiments of Roddaro et al. [1], is addressed. We are particularly concerned here with the insulating behavior--the phenomena of backscattering enhancement induced at high gate voltages. Electrostatics calculations for QH systems with split gates performed here show that observations are not a consequence of interedge interactions near the point contact. We attribute the phenomena of backscattering enhancement to a splitting of the integer edge into conducting and insulating stripes, which enable the occurrence of the more relevant backscattering processes of fractionally charged quasiparticles at the point contact. For the values of the parameters used in the experiments we find that the conducting channels are widely separated by the insulating stripes and that their presence alters significantly the low-energy dynamics of the edges. Interchannel impurity scattering does not influence strongly the tunneling exponents as they are found to be irrelevant processes at low energies. Exponents of backscattering at the point contact are unaffected by interchannel Coulomb interactions since all channels have same chirality of propagation.

Exploring the phenomenon of recovery for chemically dependent women survivors of childhood sexual abuse
Creators: name: Oxner, Katherine B.
Publisher: name: University of British Columbia
Year: 2008

description: This study explores the influence of childhood sexual abuse on the recovery process from chemical dependence for women. A feminist perspective is utilized in the qualitative design which elicited rich information from the interviews held with eight women The participants who volunteered, were referred by their counsellors from a Drug and Alcohol residential treatment program and out-patient clinic. The recovery stories as shared by these women were audio taped and the interpretation of their responses was directed by the grounded theory method of data analysis. Two themes emerged from the analysis: 1) Self-Discovery Through Story Sharing and, 2) Symptomatic Relapse, which captured the complex intertwining nature of recovery from chemical dependence where the process is compounded by the aftereffects of childhood sexual abuse trauma. All eight women reported a desire to maintain a drug and alcohol free lifestyle but repeatedly found themselves abusing substances until they understood the connection between their addiction patterns and the aftereffects of being survivors of childhood sexual abuse. Chemical dependence and childhood sexual abuse have been viewed as distinct "treatment" issues, however, these findings suggest the issues be addressed simultaneously if chemical abstinence is to be a realized goal in recovery.

As the Maupertuis-Jacobi principle in classical mechanics, this result allows us, in principle, to infer some of the dynamical properties of the cosmologies from the geometry of the associated augmented spaces.

description: We construct fast algorithms for evaluating transforms associated with families of functions which satisfy recurrence relations. These include algorithms both for computing the coefficients in linear combinations of the functions, given the values of these linear combinations at certain points, and, vice versa, for evaluating such linear combinations at those points, given the coefficients in the linear combinations; such procedures are also known as analysis and synthesis of series of certain special functions. The algorithms of the present paper are efficient in the sense that their computational costs are proportional to n (ln n) (ln(1/epsilon))^3, where n is the amount of input and output data, and epsilon is the precision of computations. Stated somewhat more precisely, we find a positive real number C such that, for any positive integer n > 10, the algorithms require at most C n (ln n) (ln(1/epsilon))^3 floating-point operations and words of memory to evaluate at n appropriately chosen points any linear combination of n special functions, given the coefficients in the linear combination, where epsilon is the precision of computations.

description: The inhalation of air-borne toxicants is associated with adverse health outcomes which can be somewhat mitigated by enhancing endogenous anti-oxidant capacity. Carnosine is a naturally occurring dipeptide (β-alanine-L-histidine), present in high abundance in skeletal and cardiac muscle. This multi-functional dipeptide has anti-oxidant properties, can buffer intracellular pH, chelate metals, and sequester aldehydes such as acrolein. Due to these chemical properties, carnosine may be protective against inhaled pollutants which can contain metals and aldehydes and can stimulate the generation of electrophiles in exposed tissues. Thus, assessment of carnosine levels, or levels of its acrolein conjugates (carnosine-propanal and carnosine-propanol) may inform on level of exposure and risk assessment. We used established mass spectroscopy methods to measure levels of urinary carnosine (n = 605) and its conjugates with acrolein (n = 561) in a subset of participants in the Louisville Healthy Heart Study (mean age = 51 ± 10; 52% male). We then determined associations between these measures and air pollution exposure and smoking behavior using statistical modeling approaches. We found that higher levels of non-conjugated carnosine, carnosine-propanal, and carnosine-propanol were significantly associated with males (p < 0.02) and those of Caucasian ethnicity (p < 0.02). Levels of carnosine-propanol were significantly higher in never-smokers (p = 0.001) but lower in current smokers (p = 0.037). This conjugate also demonstrated a negative association with mean-daily particulate air pollution (PM2.5) levels (p = 0.01). These findings suggest that urinary levels of carnosine-propanol may inform as to risk from inhaled pollutants.

description: The aim of the present thesis was the study of the institution of asylia (inviolability) in the Hellenistic period. We examined the institution using as our main methodology the interstate networks of the Ecumene, however we took into consideration other methodological approaches like numismatics, the study of emotions and cognitive historiography. We dealt with the separation of networks, the relation that cities built in the Hellenistic era, and the ways the institution of asylia could contribute to further communication between the cities. At the same time we dealt with other interstate institutions of the same era, but also with phenomena related to the institution of asylia, like piracy.
The changing construction of the human being in medical discourse concerning melancholy
Creators: name: Patterson, Lois R.
Publisher: name: University of British Columbia
Year: 2008

description: The latter half of the seventeenth century brought the scientific revolution and a new style and habit of thought. This thesis examines medical texts from the period 1620-1750in order to relate the changes wrought by the scientific revolution to changes in the ways physicians envisioned the nature of the human being. In order to narrow the scope of this study, this thesis will focus on a particular ailment, melancholy. Melancholy was considered a disorder which affected all parts of a human being, however his or her components were subdivided. Thus, a physician's discussion of melancholy reveals his perception of how the human being was constructed. Robert Burton's Anatomy of Melancholy, first published in 1621, reflects the sum of classical and medieval understanding of the human being -- the soul, the body, and their interaction -- and it forms the basis of this study. The Anatomy serves as a touchstone by which to compare later texts. The other works studied are representative of their period, and they are thoughtful texts which describe physiology and melancholy at length. This thesis begins by describing Burton's model of the human being, and then discusses the definitions of melancholy used by later medical authorities. The symptoms, causes, and cures which Burton attributes to melancholy are compared to those of later writers. The construction of the human being which emerges from The Anatomy is related to that which emerges from later works, and the moral and social implications of this change are discussed. In the eighteenth century, the human being is increasingly viewed as a collection of components, rather than the type of intrinsic whole which Burton perceived him or her to be. Human beings are discussed separately from their surroundings, rather than in conjunction with their position in society. The soul becomes insignificant to physicians as they begin to focus their attention solely on the concrete and tangible body.
Effect of grid sensitivity on the performance of wall adapting SGS models for LES of swirling and separating reattaching flows
Creators: name: Arya, Nitish

Year: 2021
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: The present study assesses the performance of the Wall Adapting SGS models along with the Dynamic Smagorinsky model for flows involving separation, reattachment and swirl. Due to the simple geometry and wide application in a variety of engineering systems, the Backward-Facing Step (BFS) geometry and Confined Swirling Flow (CSF) geometry are invoked in the present case. The calculation of the SGS stresses employs three models, namely, the Dynamic Smagorinsky model, the Wall Adapting Local Eddy viscosity (WALE) model and the Dynamic WALE model. For studying the effect of the grid sensitivity, the simulations are performed over two sets of grids with different resolutions based on the non-dimensional wall distance parameter ( y+ ). Grids corresponding to y+ = 70 and y+ = 20 are employed for the subsonic flow over the BFS while grids corresponding to y+ = 40 and y+ = 20 are employed for supersonic flow over the BFS and for confined swirling flow geometry. The validation against the experimental results includes the mean flow fields and the turbulent stresses obtained for each case. The results reveal that for the fine grid (y+ = 20), the near wall eddy viscosity profile for the WALE model is better than both the Dynamic WALE and the Dynamic Smagorinsky model. The difference between the predictions of the coarse and fine grids for Dynamic Smagorinsky and the WALE model is high whereas, the Dynamic WALE model is almost insensitive to the grid resolutions considered for the present case. The mean velocity and pressure values as well as the turbulent quantities predicted by the Dynamic WALE model are closest to the experimental values for all the cases.

description: In this paper, we present consistent and inconsistent discontinuous Galerkin methods for incompressible Euler and Navier-Stokes equations with the kinematic pressure, Bernoulli function and EMAC function. Semi- and fully discrete energy stability of the proposed dG methods are proved in a unified fashion. Conservation of total energy, linear and angular momentum is discussed with both central and upwind fluxes. Numerical experiments are presented to demonstrate our findings and compare our schemes with conventional schemes in the literature in both unsteady and steady problems. Numerical results show that global conservation of the physical quantities may not be enough to demonstrate the performance of the schemes, and our schemes are competitive and able to capture essential physical features in several benchmark problems.

Low mass X-ray binaries with pre-main sequence companions

Subjects: subject: Astrophysics (astro-ph)

description: In this Letter we examine the idea that a subset of short-period black-hole low-mass X-ray binaries could be powered by the mass transfer from pre-main sequence donors. As the star contracts towards the main sequence, the strong magnetic fields operate the magnetic braking which dissipates the orbital angular momentum, driving the binary to contact. We show that the periods and apparent donor spectral classes of the X-ray binaries with a pre-main sequence donor agree better with the available observations of black hole X-ray binaries than those of binaries with a main-sequence donor. This mechanism also explains, without the need for additional hypotheses, the roughly primordial abundance of Li detected in donor companions of black hole X-ray candidates in our Galaxy.

description: Σκοπός της διπλωματικής εργασίας ήταν η αφηγηματική ανάλυση κατά G. Genette του διηγήματος Η Σειρήνα του Ιταλού συγγραφέα Τζουζέπε Τομάζι ντι Λαμπεντούζα. Μετά από μια αρχική αναφορά στη ζωή και την ποιητική του συγγραφέα γενικά αλλά και ειδικά στο υπό εξέταση διήγημα, αναλύθηκαν ο μύθος και συγκεκριμένα ο τόπος, ο χρόνος και τα πρόσωπα. Ακολούθησε εξέταση της πλοκής με παρουσίαση της δομής του διηγήματος και το διαχωρισμό του σε ενότητες για πληρέστερη ανάλυση. Εκεί απασχόλησαν οι σχέσεις των χαρακτήρων μεταξύ τους, η διαφορά ανάμεσα στο χρόνο της ιστορίας και αυτόν της αφήγησης, το είδος του αφηγητή και της εστίασης. Έπειτα το ενδιαφέρον επικεντρώθηκε σε κάποιες θεματικές που αναπτύχθηκαν κατ' επιλογή όπως η παρουσία του φανταστικού και η σχέση του με τα αρχέτυπα κατά Γιουνγκ καθώς το κείμενο παρουσιάζει πληθώρα αντιθετικών συμβολισμών που εμπίπτουν στη θεωρία του Ελβετού γιατρού και ψυχολόγου και φτάνουν ως τη μεταφυσική εμπειρία εκκινώντας από το σουρεαλιστικό συμβάν της νιότης του πρωταγωνιστή. Κλείνοντας έγινε μια σύντομη αναφορά στο ρόλο της σειρήνας ως μυθικό πλάσμα, ως σύμβολο και ως αρχέτυπο.
description: The aim of the present thesis was the narratological analysis according to G. Genette of the short story The professor and the siren by the Italian writer Giuseppe Tomasi di Lampedusa. After an inceptive reference to his life and his poetic generally and specifically in the short story in consideration, the myth and in particular the place, the time and the characters have been analyzed. A study of the plot and the separation of the short story in unities followed for a more complete analysis. The relations between the characters, the difference between the time of the story and that of the narration, the kind of the narrator and the focus were what was evaluated as far as the plot is concerned. Certain topics were studied selectively such as the fantastic element and its relation with the archetypes as presented by Jung. The text presents a surfeit of contrasting symbolisms that reach the metaphysical experience starting from the surreastic incidence in the youth of the professor. In the end a short reference to the role of the siren as a mythical creature, as a symbol and as an archetype took place.

description: Affective Computing has recently attracted the attention of the research community, due to its numerous applications in diverse areas. In this context, the emergence of video-based data allows to enrich the widely used spatial features with the inclusion of temporal information. However, such spatio-temporal modelling often results in very high-dimensional feature spaces and large volumes of data, making training difficult and time consuming. This paper addresses these shortcomings by proposing a novel model that efficiently extracts both spatial and temporal features of the data by means of its enhanced temporal modelling based on latent features. Our proposed model consists of three major networks, coined Generator, Discriminator, and Combiner, which are trained in an adversarial setting combined with curriculum learning to enable our adaptive attention modules. In our experiments, we show the effectiveness of our approach by reporting our competitive results on both the AFEW-VA and SEWA datasets, suggesting that temporal modelling improves the affect estimates both in qualitative and quantitative terms. Furthermore, we find that the inclusion of attention mechanisms leads to the highest accuracy improvements, as its weights seem to correlate well with the appearance of facial movements, both in terms of temporal localisation and intensity. Finally, we observe the sequence length of around 160\,ms to be the optimum one for temporal modelling, which is consistent with other relevant findings utilising similar lengths.

Is the outer Solar System chaotic?

description: The existence of chaos in the system of Jovian planets has been in question for the past 15 years. Various investigators have found Lyapunov times ranging from about 5 millions years upwards to infinity, with no clear reason for the discrepancy. In this paper, we resolve the issue. The position of the outer planets is known to only a few parts in 10 million. We show that, within that observational uncertainty, there exist Lyapunov timescales in the full range listed above. Thus, the ``true'' Lyapunov timescale of the outer Solar System cannot be resolved using current observations.

description: Hybrid Reynolds-averaged Navier Stokes large eddy simulation (RANS LES) methods have become popular for simulation of massively separated flows at high Reynolds numbers due to their reduced computational cost and good accuracy. The current study aims to examine the performance of LES and hybrid RANS-LES model for a given grid resolution. For better assessment and contrast of model performance, both mean and instantaneous flow fields have been investigated. For studying instantaneous flow, proper orthogonal decomposition has been used. Current analysis shows that hybrid RANS-LES is capable of achieving similar accuracy in prediction of both mean and instantaneous flow fields at a very coarse grid as compared to LES. Focusing mostly on the practical applications of computation, most of the attention has been given to the prediction of one-point flow statistics and little consideration has been put to two-point statistics. Here, two-point statistics has been considered using POD to investigate unsteady turbulent flow.

description: Σκοπός της διατριβής ήταν η μελέτη της σύμβασης μάνατζμεντ ή σύμβασης διοίκησης και διαχείρισης επιχείρησης. Πρόκειται για τη σύμβαση με την οποία μία επιχείρηση (μάνατζερ, δότης του μάνατζμεντ) αναλαμβάνει έναντι αμοιβής να διοικήσει την επιχείρηση άλλου (αναθέτουσα επιχείρηση, λήπτης του μάνατζμεντ) στο όνομα, για λογαριασμό και με κίνδυνο της τελευταίας. Αρχικά, εξετάσαμε τη νομική φύση αυτής της σύμβασης και τη διάκρισή της από συγγενείς συμβάσεις. Στη συνέχεια, παρουσιάσαμε αναλυτικά την κατάρτιση της σύμβασης και τα θέματα που δημιουργούνται όταν και τα δύο μέρη είναι νομικά πρόσωπα, δίνοντας ιδιαίτερη έμφαση στο Εταιρικό Δίκαιο. Ακόμη, αναφερθήκαμε αναλυτικά στις υποχρεώσεις που βαρύνουν τα δύο μέρη, δηλαδή το δότη και το λήπτη του μάνατζμεντ. Ένα άλλο θέμα που θίξαμε ήταν η ευθύνη της εταιρίας μάνατζμεντ έναντι της αναθέτουσας επιχείρησης και έναντι τρίτων. Τέλος, έγινε λόγος για τους λόγους λήξης της σύμβασης και τις συνέπειές της.
description: The aim of the present thesis was the study of management contract or management agreement. It’s the agreement, in which one company (manager, giver of management) undertakes the management of another company (contracting business, receiver of management), in the name, on behalf and with risk of the contracting business. Firstly, we presented the legal nature of this agreement and the difference of this agreement from relevant agreements. Furthermore, we analyzed the contracting of this agreement and the issues resulting from the examined management agreement between two legal entities focusing on the Company Law. We also examined the obligations of the two parts of the agreement (giver and receiver of management). Another aim of this study was to examine the liability of the manager against the contracting business and against the third parties. Last but not least, we presented the reasons that lead to the end of the agreement and the consequences of that ending.

A Generic Model for Current Collapse in Spin Blockaded Transport

description: A decrease in current with increasing voltage, often referred to as negative differential resistance (NDR), has been observed in many electronic devices and can usually be understood within a one-electron picture. However, NDR has recently been reported in nanoscale devices with large single-electron charging energies which require a many-electron picture in Fock space. This paper presents a generic model in this transport regime leading to a simple criterion for the conditions required to observe NDR and shows that this model describes the recent observation of multiple NDR's in Spin Blockaded transport through weakly coupled-double quantum dots quite well. This model shows clearly how a delicate interplay of orbital energy offset, delocalization and Coulomb interaction lead to the observed NDR under the right conditions, and also aids in obtaining a good match with experimentally observed features. We believe the basic model could be useful in understanding other experiments in this transport regime as well.

description: A growing number of researchers suggest that software process must be tailored to a project's context to achieve maximal performance. Researchers have studied 'context' in an ad-hoc way, with focus on those contextual factors that appear to be of significance. The result is that we have no useful basis upon which to contrast and compare studies. We are currently researching a theoretical basis for software context for the purpose of tailoring and note that a deeper consideration of the meaning of the term 'context' is required before we can proceed. In this paper, we examine the term and present a model based on insights gained from our initial categorisation of contextual factors from the literature. We test our understanding by analysing a further six documents. Our contribution thus far is a model that we believe will support a theoretical operationalisation of software context for the purpose of process tailoring.
