description: X-Ray Flashes (XRFs) are soft gamma-ray bursts whose nature is not clear. Their soft spectrum can be due to cosmological effects (high redshift), an off-axis view of the jet or can be intrinsic to the source. We use SWIFT observations to investigate different scenarios proposed to explain their origin. We have made a systematic analysis of the afterglows of XRFs with known redshift observed by SWIFT. We derive their redshift and luminosity distributions, and compare their properties with a sample of normal GRBs observed by the same instrument. The high distance hypothesis is ruled out by the redshift distribution of our sample of XRFs, indicating that, at least for our sample, the off-axis and sub-energetic hypotheses are preferred. Of course, this does not exclude that some XRFs without known redshift could be at high distance. However we find that taking into account the sensitivity of the BAT instrument, XRFs cannot be detected by SWIFT beyond ~ 3. The luminosity distribution of XRF afterglows is similar to the GRB one. This would rule out most off-axis models, but for the homogeneous jet model. However this model predicts a GRB rate uncomfortably near the observed rate of supernovae. This implies that XRFs, at least those of our sample, are intrinsically soft.

description: We present spectral measurements of spin-wave excitations driven by direct spinpolarized current in the free layer of nanoscale Ir20Mn80/Ni80Fe20/Cu/Ni80Fe20 spin valves. The measurements reveal that large-amplitude coherent spin wave modes are excited over a wide range of bias current. The frequency of these excitations exhibits a series of jumps as a function of current due to transitions between different localized nonlinear spin wave modes of the Ni80Fe20 nanomagnet. We find that micromagnetic simulations employing the Landau-Lifshitz-Gilbert equation of motion augmented by the Slonczewski spin torque term (LLGS) accurately describe the frequency of the current-driven excitations including the mode transition behavior. However LLGS simulations give qualitatively incorrect predictions for the amplitude of excited spin waves as a function of current.

description: The biodegradation of benzene series compounds is a difficult problem in environment pollution control, which is attributed to the deficiency of high efficiency bacteria and suitable embedding materials. In this study, the immobilized cells Rhodococcussp. strain PB-1 was used to synchronously biodegrade phenol and aniline by entrapped in sodium alginate (SA)-bamboo charcoal (BC)-chitosan acetate (CA) beads. The free cells of the strain PB-1 could completely degrade 1500 mg/L phenol or 800 mg/L aniline within 48 h, while the degradation rate of 2000 mg/L phenol and 1500 mg/L aniline was 35.76% and 68.06% at 72 h, respectively. The ortho-cleavage pathway was used to degrade phenol and aniline by strain PB-1. However, after entrapped with SA-BC-CA beads,the removal rate of 2000 mg/L phenol was 100% at 108 h, 1500 mg/L aniline was 100% at 62 h and 2000–3000 mg/L total toxic compounds was over 95% at 120 h. These beads could be used four times and were more effective than SA or SA-BC beads. The SA-BC-CA beads could remarkably improve the stability and degradation efficiency of strain PB-1, and thus provide a potential application in the removal of phenol and aniline in wastewater.

description: In recent work we formulated a new set of electrodynamic equations for superconductors as an alternative to the conventional London equations, compatible with the prediction of the theory of hole superconductivity that superconductors expel negative charge from the interior towards the surface. Charge expulsion results in a macroscopically inhomogeneous charge distribution and an electric field in the interior, and because of this a spin current is expected to exist. Furthermore, we have recently shown that a dynamical explanation of the Meissner effect in superconductors leads to the prediction that a spontaneous spin current exists near the surface of superconductors. In this paper we extend the electrodynamic equations proposed earlier for the charge density and charge current to describe also the space and time dependence of the spin density and spin current. This allows us to determine the magnitude of the expelled negative charge and interior electric field as well as of the spin current in terms of other measurable properties of superconductors. We also provide a 'geometric' interpretation of the difference between type I and type II superconductors, discuss the relationship between our model and Slater's seminal work on superconductivity, and discuss the magnitude of the expected novel effects for elemental and other superconductors.

Anomalous SZ Contribution to 3 Year WMAP Data
Creators: name: Bielby, R. M.

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We first show that the new WMAP 3 year data confirm the detection by Myers et al 2004 of an extended SZ signal centred on 606 Abell (ACO) clusters with richness class, R>1. Our results also show SZ decrements around APM and 2MASS groups at increased significance than previously detected. We then follow the approach of Lieu et al 2006 and compare the stacked WMAP results for the decrement in 31 clusters with ROSAT X-ray profiles where Lieu et al found on average less SZ decrement in the WMAP 1 year data than predicted. We confirm that in the 3 year data these same clusters again show less SZ decrement than the X-ray data predicts. We then analysed the WMAP results for the 38 X-ray clusters with OVRO/BIMA measured SZ decrements as presented by Bonamente et al 2006. We again find that the average decrement is measured to be significantly less (5.5 sigma) than predicted by the Chandra X-ray data. Thus while we confirm the original detection of an extended SZ effect by Myers et al 2004, these X-ray comparisons may now suggest that the central SZ amplitudes detected by WMAP may actually be lower than expected. One possible explanation is that there is contamination of the WMAP SZ signal by radio sources in the clusters but we argue that this appears implausible. We then consider the possibility that the SZ decrement has been lensed away by foreground galaxy groups. Such a model predicts that the SZ decrement should depend on cluster redshift. A reduction in the SZ decrement with redshift is suggested from the ACO cluster sample and also from comparing the samples of Lieu et al 2006 and Bonamente et al 06. However, the mass power-spectrum would require a far higher amplitude than currently expected if lensing was to explain the SZ deficit in high redshift clusters.

description: Context. The microquasar 1E 1740.7-2942 is a source located in the direction of the Galactic Center. It has been detected at X-rays, soft gamma-rays, and in the radio band, showing an extended radio component in the form of a double-sided jet. Although no optical counterpart has been found so far for 1E 1740.7-2942, its X-ray activity strongly points to a galactic nature. Aims. We aim to improve our understanding of the hard X-ray and gamma-ray production in the system, exploring whether the jet can emit significantly at high energies under the light of the present knowledge. Methods. We have modeled the source emission, from radio to gamma-rays, with a cold-matter dominated jet model. INTEGRAL data combined with radio and RXTE data, as well as EGRET and HESS upper-limits, are used to compare the computed and the observed spectra. Results. From our modeling, we find out that jet emission cannot explain the high fluxes observed at hard X-rays without violating at the same time the constraints from the radio data, favoring the corona origin of the hard X-rays. Also, 1E 1740.7-2942 might be detected by GLAST or AGILE at GeV energies, and by HESS and HESS-II beyond 100 GeV, with the spectral shape likely affected by photon-photon absorption in the disk and corona photon fields.

description: Modeling of signal transduction pathways is of the utmost importance in understanding how cells respond to environmental perturbations. Signaling pathways consist of a set of protein protein interactions, identified via high throughput proteomic experiments and made available through on line pathway databases. Over the past few years a range of methods have been proposed to model these networks in an attempt to gain insight into the cells function and uncover the etiology underlying complex disease. Aim of this work is the development of a novel class of methodologies that model signal transduction networks as logic models, and using regular optimizatino formulations cross reference them with high throughput proteomic data to construct predictive models of the signaling mechanisms of the interrogated cell lines

The relationship among perceived social support, self-critical cognition and neurotic symptoms in rehabilitation medicine students : a correlational study
Creators: name: McGinity, Alix M.
Publisher: name: University of British Columbia
Year: 2008

description: A review of the literature indicates that a significant number of students are psychologically distressed during their professional education. Most of the research in this area focuses on sources of stress for students, usually confined to factors within the scope of the educational experience. Researchers generally agree, however, that stress experienced in a given situation is largely a function of an individual's perception of the circumstances and that characteristics of the situation, characteristics of the individual and mediating factors external to the situation are all determinants. The purpose of this descriptive, exploratory study was to examine the relationship among the following psychological variables among second, third and fourth year students in a rehabilitation medicine program: (a) the perception of available social support and satisfaction with this social support, (b) the tendency to process self-relevant information in self-critical and self-defeating ways, and (c) the manifestation of psychological distress in the form of neurotic symptoms. A sample of 83 students (73 females and 10 males) in an occupational therapy and a physical therapy program completed the Social Support Questionnaire, the Self-Critical Cognition Scale, and the Hopkins Symptom Checklist. The Social Support Questionnaire included two dimensions; (a) the availability of perceived social support; and (b) satisfaction with perceived social support. The Hopkins Symptom Checklist included five dimensions; (a) somatization; (b) obsession-compulsion; (c) interpersonal sensitivity; (d) depression; and (e) anxiety. A Pearson Product-moment correlational analysis was conducted on the two Social Support Questionnaire dimension scores, the five Hopkins Symptom Checklist dimension scores and the Self-Critical Cognition scores. A series of t tests were done to examine differences on the variables between occupational and physical therapy students as well as a one-way ANOVA among three groups according to the year in the program. The results showed that both perceived availability of social support and satisfaction with social support correlated significantly, in a negative direction, with self-critical cognition (p < .001). The two measures of the social support variable also correlated significantly, in a negative direction, with all dimensions of the Hopkins Symptom Checklist (p < .001) except somatization. There was no statistically significant difference between occupational therapy students and physical therapy students. The ANOVA revealed that third year students were statistically significantly more obsessive-compulsive than second and fourth year students (p < .05).
Development of a Dyadic Partner Validation Scale

Publisher: name: University of British Columbia
Year: 2008

description: Self-validation is a process of restoring or enhancing one's wellbeing around the five interrelated thematic components of the self-validation model developed by Ishiyama, (1987, 1989). The thematic components of comfort, support,and security: self-worth and self-acceptance; competence, and autonomy; identity and belonging; and love, fulfillment and meaning in life are essential for self-validation and relationship validation. The Dyadic Parmer Validation Scale was developed to measure this construct This study tested the psychometric properties of Dyadic Partner Validation Scale. Item-total correlations ranged from .24 - .93, internal consistency correlations (Cronbach alpha) at .82, .81 and .70 and with a test-retest coefficient of .79 and .85 over a three week time period. Reliability correlations for the Dyadic Partner Validation Scale were high. As hypothesized, relationship validation measured by the Dyadic Partner Validation Scale had high positive correlation (.59, .75 and .78) with relationship satisfaction measured by the Dyadic Adjustment Scale. This hypothesis was accepted. It was hypothesized that relationship validation would have high negative correlations (.19, -.21 and -.30) with self-esteem measured by Rosenberg's Self Esteem Scale and high negative correlations ( .01, -.17 and -.33) with indices of mental health measured by Hopkin's Symptom Checklist This hypothesis was not supported but the correlations were moving in the expected negative direction. The Dyadic Partner Validation Scale was found to have predictive validity with relationship satisfaction. This scale provides a useful assessment tool for clinical and research purposes in studying marital and nonmarital relationships.

description: We present a new approach to gravitational lens massmap reconstruction. Our massmap solutions perfectly reproduce the positions, fluxes, and shears of all multiple images. And each massmap accurately recovers the underlying mass distribution to a resolution limited by the number of multiple images detected. We demonstrate our technique given a mock galaxy cluster similar to Abell 1689 which gravitationally lenses 19 mock background galaxies to produce 93 multiple images. We also explore cases in which far fewer multiple images are observed, such as four multiple images of a single galaxy. Massmap solutions are never unique, and our method makes it possible to explore an extremely flexible range of physical (and unphysical) solutions, all of which perfectly reproduce the data given. Each reconfiguration of the source galaxies produces a new massmap solution. An optimization routine is provided to find those source positions (and redshifts, within uncertainties) which produce the "most physical" massmap solution, according to a new figure of merit developed here. Our method imposes no assumptions about the slope of the radial profile nor mass following light. But unlike "non-parametric" grid-based methods, the number of free parameters we solve for is only as many as the number of observable constraints (or slightly greater if fluxes are constrained). For each set of source positions and redshifts, massmap solutions are obtained "instantly" via direct matrix inversion by smoothly interpolating the deflection field using a recently developed mathematical technique. Our LensPerfect software is straightforward and easy to use and is made publicly available via our website.

description: Η σύμπτωση των τοιχωμάτων της τραχείας(ΣΤΤ) είναι συχνά εμφανιζόμενο νόσημα σε μικρόσωμες, μέσως ηλικίας φυλές σκύλες. Μέχρι σήμερα η μέθοδος εκλογής για τη διάγνωση και σταδιοποίηση του νοσήματος είναι η τραχειοσκόπηση με βάση την οποία γίνεται η διάκριση του νοσήματος σε 4 στάδια. Τόσο στον άνθρωπο όσο και στο σκύλο η παραπάνω μέθοδος τείνει να αντικατασταθεί λόγω των κινδύνων που εγκυμονεί. Στόχος της παρούσας μελέτης ήταν να διερευνήσει εάν η καμπύλη Ροής-Ογκου σε αυτόματη αναπνοή, μία απλή γρήγορη και ακίνδυνη λειτουργική δοκιμή ελέγχου της αναπνευστικής λειτουρφίας μπορεί να θέσει διάγνωση και να σταδιοποιήσει τη ΣΤΤ. Σύμφωνα με τα αποτελέσματα της παρούσας μελέτης προσδιορίζοντας τρεις μόνο παραμέτρους της παραπάνω δοκιμής (ΤΕ/ΤΙ, ΤΙ/ΤΤΟΛ, ΕF75/ΙF75) αυτό είναι εφικτό σε ποσοστό 97,4% των περιστατικών
description: Tracheal collapse(TC) is mostly diagnosed in middle aged, toy breed dogs. The gold standard method in the diagnosis and staging of the disease is tracheoscopy according to which TC is categorized into four stages. In both humans an and dogs tracheoscopy is sometimes withheld due to its complications. The aim of this study was to investigate, whether Tidal breathing flow-volume loop, a simple, fast and harmfull pulmonary function test is able to diagnose the disease. According to the results of this study the measurement of only three parameters of TBFVL is adequeate for diagnosis and stageing of the disease(TE/TI, TI/TTOL, EF75/IF75)with a sensitivity of 97,4% of the cases

description: The rigorous explanation for the term $| t |^{2β}$ in the rectilinear diameter equation is given ($t = (T_c-T)/T_c$, $β$ is the critical exponent for the asymptotic form of the equation of state). The optimal order parameter, for which the branches of binodal are symmetric is constructed within the canonical formalism. It is shown that the ratio of the amplitudes $\f{D_{2β}}{D_{1-α}}$ before $|t|^{2β}$ and $|t|^{1-α}$ where $α$ determines the behavior of the heat capacity, takes the universal character. The analysis of entropy for argon and water leads to $β= 0.33$ and $\f{D_{2-β}}{D_{1-α}}\approx - 3.5$.

description: We investigated the possibility of temperature dependent lattice distortions in the pyrochlore compound Tb$_{2}$Ti$_{2}$O$_{7}$ by measuring the internal magnetic field distribution, using muon spin resonance, and comparing it to the susceptibility. The measurements are done at temperatures as low as 70 mK and external fields up to 6 kG. We find that the evolution of the width of the field distribution can be explained by spin susceptibility only, thus ruling out a temperature dependent hyperfine coupling. We conclude that lattice deformations are absent in Tb$_{2}$Ti$_{2}$O$_{7}$.

description: In this paper, we present an analysis of a chiral cosmological scenario from the perspective of K-essence formalism. In this setup, several scalar fields interact within the kinetic and potential sectors. However, we only consider a flat Friedmann--Robertson--Lama\^ıtre--Walker universe coupled minimally to two quintom fields: one quintessence and one phantom. We examine a classical cosmological framework, where analytical solutions are obtained. Indeed, we present an explanation of the ``big-bang'' singularity by means of a ``big-bounce''. Moreover, having a barotropic fluid description and for a particular set of parameters, the phantom line is in fact crossed. Additionally, for the quantum counterpart, the Wheeler--DeWitt equation is analytically solved for various instances, where the factor-ordering problem has been taken into account (measured by the factor Q). Hence, this approach allows us to compute the probability density of the previous two classical subcases. It turns out that its behavior is in effect damped as the scale factor and the scalar fields evolve. It also tends towards the phantom sector when the factor ordering constant $\rm Q\ll 0$.

description: Στην παρούσα διατριβή μελετάται η ασφαλής βιομετρική πιστοποίηση με τεχνικές κωδικοποίησης κατανεμημένων πηγών. Συγκεκριμένα, αρχικά εξετάζεται ένα νέο σχήμα βιομετρικής πιστοποίησης που βασίζεται σε κώδικες διόρθωσης λαθών και το θεώρημα Slepian-Wolf και αναλύεται η προστασία που παρέχει στα βιομετρικά πρότυπα. Στη συνέχεια, περιγράφεται ένα νέο σύστημα βιομετρικής πιστοποίησης από ακολουθίες βαδίσματος. Προτείνονται νέοι μετασχηματισμοί για την εξαγωγή των κτυριότερων χαρακτηριστικών από την ανθρώπινη σιλουέτα και αναπτύσσονται αναλυτικά πιθανοτικά μοντέλα για τη μοντελοποίηση των ενδοατομικών παραλλαγών. Επίσης, εξετάζεται ένα πολυτροπικό βιομετρικό σύστημα από εικόνες προσώπου και ακολουθίες βαδίσματος επεκτείνοντας το θεώρημα Slepian-Wolf για τη κωδικοποίηση πολλαπλών κατανεμημένων πηγών. Τέλος, προτείνεται μια νέα μέθοδος παρεμβολής εικόνων βασισμένη στην εκτίμηση κίνησης με δυναμικά μεταβαλλόμενο μέγεθος μπλοκ για την κωσικοποίηση εικονοσειρών Wyner-Ziv που βελτιώνει σημαντικά το αποτέλεσμα προγούμενων μεθόδων
description: This thesis addresses the problem of secure biometric verication using distributed source coding principles. Specically, a novel biometric authentication scheme based on error correcting codes and the Slepian-Wolf theorem is initially examined and the biometric template protection is analyzed. Next, a novel gait authentication system is described. New transforms are proposed for meaningful feature extraction from human silhouettes and analytic probabilistic models are developed to model intra-personal variations. Also, a multimodal biometric system based on face and gait authentication is investigated based on the extension of the Slepian-Wolf theorem for distributed source coding of multiple sources. Finally, a novel frame interpolation method for Wyner-Ziv video coding is proposed based on motion estimation using dynamically adapted block size, which surpasses the performance of state-of-the-art methods
Moiré-pattern evolution couples rotational and translational friction at crystalline interfaces

description: The sliding motion of objects is typically governed by their friction with the underlying surface. Compared to translational friction, however, rotational friction has received much less attention. Here, we experimentally and theoretically study the rotational depinning and orientational dynamics of two-dimensional colloidal crystalline clusters on periodically corrugated surfaces in the presence of magnetically exerted torques. We demonstrate that the traversing of locally commensurate areas of the moiré pattern through the edges of clusters, which is hindered by potential barriers during cluster rotation, controls its rotational depinning. The experimentally measured depinning thresholds as a function of cluster size strikingly collapse onto a universal theoretical curve which predicts the possibility of a superlow-static-torque state for large clusters. We further reveal a cluster-size-independent rotation-translation depinning transition when lattice-matched clusters are driven jointly by a torque and a force. Our work provides guidelines to the design of nanomechanical devices that involve rotational motions on atomic surfaces.

description: The space of positively curved hermitian metrics on a positive holomorphic line bundle over a compact complex manifold is an infinite-dimensional symmetric space. It is shown by Phong and Sturm that geodesics in this space can be uniformly approximated by geodesics in the finite dimensional spaces of Bergman metrics. We prove a stronger C^2-approximation in the special case of toric (i.e. S^1-invariant) metrics on CP^1.
