description: Motivated by the recently discovered class of faint (10^34-10^35 ergs/s) X-ray transients in the Galactic Center region, we investigate the 2-10 keV properties of classical and recurrent novae. Existing data are consistent with the idea that all classical novae are transient X-ray sources with durations of months to years and peak luminosities in the 10^34-10^35 ergs/s range. This makes classical novae a viable candidate class for the faint Galactic Center transients. We estimate the rate of classical novae within a 15 arcmin radius region centered on the Galactic Center (roughly the field of view of XMM-Newton observations centered on Sgr A*) to be ~0.1 per year. Therefore, it is plausible that some of the Galactic Center transients that have been announced to date are unrecognized classical novae. The continuing monitoring of the Galactic Center region carried out by Chandra and XMM-Newton may therefore provide a new method to detect classical novae in this crowded and obscured region, where optical surveys are not, and can never hope to be, effective. Therefore, X-ray monitoring may provide the best means of testing the completeness of the current understanding of the nova populations.

description: High quality factor ($Q$) nanomechanical resonators have received a lot of attention for sensor applications with unprecedented sensitivity. Despite the large interest, few investigations into the frequency stability of high-$Q$ resonators have been reported. Such resonators are characterized by a linewidth significantly smaller than typically employed measurement bandwidths, which is the opposite regime to what is normally considered for sensors. Here, the frequency stability of high-$Q$ silicon nitride string resonators is investigated both in open-loop and closed-loop configurations. The stability is here characterized using the Allan deviation. For open-loop tracking, it is found that the Allan deviation gets separated into two regimes, one limited by the thermomechanical noise of the resonator and the other by the detection noise of the optical transduction system. The point of transition between the two regimes is the resonator response time, which can be shown to have a linear dependence on $Q$. Laser power fluctuations from the optical readout is found to present a fundamental limit to the frequency stability. Finally, for closed-loop measurements, the response time is shown to no longer be intrinsically limited but instead given by the bandwidth of the closed-loop tracking system. Computed Allan deviations based on theory are given as well and found to agree well with the measurements. These results are of importance for the understanding of fundamental limitations of high-$Q$ resonators and their application as high performance sensors.

Asymmetric induction and triplet sensitization in the solid state photochemistry of Anti-9-carboxybenzonorbornadiene

Publisher: name: University of British Columbia
Year: 2009

description: [Formula] Acid 19 and its methyl ester 45 were prepared, and studies of their photochemical reactivity were made in both the solution phase and solid state. Unexpectedly, both compounds underwent di-7r.-meth.ane rearrangement to the corresponding undecatrienes 54 and 53 upon direct irradiation in solution. Ester 45 reacted more rapidly in the solid state than in solution, although acid 19 did not react at all in the solid state. Although di-7t-methane rearrangement usually occurs only from the excited triplet state in constrained cyclic systems such as these, benzonorbornadiene derivatives 19 and 45 appear capable of undergoing the reaction from either the singlet or triplet excited state. Although the di-Tt-methane rearrangement would occur upon direct irradiation, the reaction was much faster when a triplet sensitizer was used. The solution phase reaction could be sensitized with acetone, acetophenone, or benzophenone. Sensitization was also possible in the solid state. Crystals of the complex formed between acid 19 and p-acetylpyridine, upon irradiation with long-wave ultraviolet light that was not absorbed by the acid (A, > 330 nm), gave rearranged product. Asymmetric induction could also be carried out. Although acid 19 is achiral, its undecatriene rearrangement product is chiral. Irradiation of crystals of salts formed between acid 19 and commercially available, optically pure, chiral amines gave optically active undecatriene products at low conversions. Enantiomeric excesses as high as 41 % were observed. Rearrangement was slow. The most rapid rearrangement occurred for the (-)-ephedrine salt of acid 19, which reached 3 1 % conversion to product after 6 hours. Crystals of acid 19 with chiral triplet sensitizer amines were also irradiated. These chiral triplet sensitizer auxiliaries were prepared by coupling natural amino acids to benzyl alcohols and phenols which contained aryl ketone groups. The auxiliaries were isolated as their hydrobromide salts and converted to the free base form immediately before use. Rearrangement of the salts formed with these chiral triplet sensitizer amines was very rapid. In the solid state, complete conversion to product occurred in less than 1 hour. Enantiomeric excesses (22% - 91%) were generally higher than those obtained upon irradiation of salts prepared with commercially available amines (5.9% - 41%).

description: Cyclin A-cyclin dependent kinase (CDK) activity is regulated by cyclin A proteolysis and CDK inhibitors (CKIs) during M and G1 phases. Our previous work has shown that constitutive activation of cyclin A-CDK in mouse somatic cells, by ectopic expression of stabilized human cyclin A2 (lacking the destruction box: CycAΔ80) in triple CKI (p21, p27, and p107)-knocked-out mouse embryonic fibroblasts, induces rapid tetraploidization. However, effects of such cyclin A-CDK hyperactivation in human cells have been unknown. Here, we show hyperactivity of cyclin A-CDK induces G2/M-phase arrest in human cell lines with relatively low expression of p21 and p27. Moreover, adenovirus E1A protein promoted CycAΔ80-derived G2/M-phase arrest by increasing the amount of cyclin A and cyclin A-CDK2 complex. This response was suppressed by an addition of ATR or Chk1 inhibitor. The amount of repressive phosphorylation of CDK1 at tyrosine 15 (Y15) was decreased by Chk1 inhibitor treatment. Moreover, we observed that co-expressing CDK1AF mutant, which is resistant to the repressive phosphorylation at threonine 14 and Y15, or cdc25A, which dephosphorylates CDK1 at Y15, suppressed the G2/M-phase arrest by CycAΔ80 with E1A. These results suggest that G2/M-phase arrest in human cells by hyperactivity of cyclin A-CDK2 is caused by repression of CDK1 via the cell cycle checkpoint ATR-Chk1 pathway.

description: Indirect detection experiments typically measure the flux of annihilating dark matter (DM) particles propagating freely through galactic halos. We consider a new scenario where celestial bodies "focus" DM annihilation events, increasing the efficiency of halo annihilation. In this setup, DM is first captured by celestial bodies, such as neutron stars or brown dwarfs, and then annihilates within them. If DM annihilates to sufficiently long-lived particles, they can escape and subsequently decay into detectable radiation. This produces a distinctive annihilation morphology, which scales as the product of the DM and celestial body densities, rather than as DM density squared. We show that this signal can dominate over the halo annihilation rate in $γ$-ray observations in both the Milky Way Galactic center and globular clusters. We use \textit{Fermi} and H.E.S.S. data to constrain the DM-nucleon scattering cross section, setting powerful new limits down to $\sim10^{-39}~$cm$^2$ for sub-GeV DM using brown dwarfs, which is up to nine orders of magnitude stronger than existing limits. We demonstrate that neutron stars can set limits for TeV-scale DM down to about $10^{-47}~$cm$^2$.

The fact that any user may tag a piece of content with any term they desire introduces significant ambiguity into the information system. As a result there was a need to use content from one or more sources on the web to provide better quality information(mashups). In the current diploma thesis we present a mashup that we created combining data from DBpedia project that extracts structured information from Wikipedia with Flick, website where users can publish their photos and apply tags to them.

description: The recently observed multiferroic behavior in the s=1/2 chain cuprate LiVCuO_4 (LiCuVO_4) with edge-shared CuO_4 plaquettes and helical spin ordering does not agree with the existing theories such as a spin-current scenario. We argue that the effect can be consistently explained, if the exchange-induced electric polarization on the out-of-chain Cu^2+ centers substituting for Li-ions in LiVCuO_4 is taken into account. These substituent centers are proved to be an effective probe of the spin incommensurability and the magnetic field effects.

description: Com'è noto, tra i requisiti fondamentali del Laboratorio del Gran Sasso, in corso di realizzazione lungo il tunnel autostradale della Roma-L'Aquila, vi è quello di mantenere al suo interno un fondo di radiazioni quanto più basso possibile.
In precedenti note(1,,2) sono stalte esaminate le due più imp~rtanti componenti del
predetto fondo di radiazioni, le rocce circostanti e i materiali da costruzione, tra cui
in primo luogo il calcestruzzo da usare per il rivestimento delle pareti del Laboratorio.
In entrambi i casi principali contributi alla radioattività totale sono risultati quellii
dovuti al K-40 e ai rad'ionucliidi delle famiglie radioattive dell'U-238 e del Th-232.
Nelle stesse note sono stati anche riportati i risultati di misure di esposizione effettuate
in vari punti della galleria autostradale.
Recentemente sono state eseguite ulteriori misure di radioattività in vari campioni
di cemento, estendendo cos' le precedenti indagini. con lo scopo questa volta di selezionare
quello piû adatto per realizzare la sorgente da utilizzare per lo studio del decadimento
del protone.
Sono state inoltre effettuate nuove misure dei livelli di esposizione nel costruendo
laboratorio e per la prima volta anche misure di concentrazione di radon in aria.

description: Thin films of the high-temperature superconductor HgBa$_2$CaCu$_2$O$_{6+δ}$ have been prepared on SrTiO$_3$ substrates by pulsed-laser deposition of precursor films and subsequent annealing in mercury-vapor atmosphere. The microstructural properties of such films can vary considerably and have been analyzed by x-ray diffraction and atomic force microscopy. Whereas the resistivity is significantly enhanced in samples with coarse-grained structure, the Hall effect shows little variation. This disparity is discussed based on models for transport properties in granular materials. We find that, despite of the morphological variation, all samples have similar superconducting properties. The critical temperatures $T_c \sim 121.2$ K $\dots 122.0$ K, resistivity, and Hall data indicate that the samples are optimally doped. The analyses of superconducting order parameter fluctuations in zero and finite magnetic fields yield the in-plane $ξ_{ab}(0) \sim 2.3$ nm $\dots 2.8$ nm and out-of-plane $ξ_{c}(0) \sim 0.17$ nm $ \dots 0.24$ nm Ginzburg-Landau coherence lengths at zero temperature. Hall measurements provide estimates of carrier scattering defects in the normal state and vortex pinning properties in the superconducting state inside the grains.

description: Stretching of a protein by a fluid flow is compared to that in a force-clamp apparatus. The comparison is made within a simple topology-based dynamical model of a protein in which the effects of the flow are implemented using Langevin dynamics. We demonstrate that unfolding induced by a uniform flow shows a richer behavior than that in the force clamp. The dynamics of unfolding is found to depend strongly on the selection of the amino acid, usually one of the termini, which is anchored. These features offer potentially wider diagnostic tools to investigate structure of proteins compared to experiments based on the atomic force microscopy.

description: Rapidly rotating early-type stars with strong magnetic fields frequently show H$α$ emission originating in Centrifugal Magnetospheres (CMs), circumstellar structures in which centrifugal support due to magnetically enforced corotation of the magnetically confined plasma enables it to accumulate to high densities. It is not currently known whether the CM plasma escapes via Centrifugal Breakout (CB), or by an unidentified leakage mechanism. We have conducted the first comprehensive examination of the H$α$ emission properties of all stars currently known to display CM-pattern emission. We find that the onset of emission is dependent primarily on the area of the CM, which can be predicted simply by the value $B_{\rm K}$ of the magnetic field at the Kepler corotation radius $R_{\rm K}$. Emission strength is strongly sensitive to both CM area and $B_{\rm K}$. Emission onset and strength are {\em not} dependent on effective temperature, luminosity, or mass-loss rate. These results all favour a CB scenario, however the lack of intrinsic variability in any CM diagnostics indicates that CB must be an essentially continuous process, i.e.\ it effectively acts as a leakage mechanism. We also show that the emission profile shapes are approximately scale-invariant, i.e.\ they are broadly similar across a wide range of emission strengths and stellar parameters. While the radius of maximum emission correlates closely as expected to $R_{\rm K}$, it is always larger, contradicting models that predict that emission should peak at $R_{\rm K}$.

description: The Lovasz theta function provides a lower bound for the chromatic number of finite graphs based on the solution of a semidefinite program. In this paper we generalize it so that it gives a lower bound for the measurable chromatic number of distance graphs on compact metric spaces. In particular we consider distance graphs on the unit sphere. There we transform the original infinite semidefinite program into an infinite linear program which then turns out to be an extremal question about Jacobi polynomials which we solve explicitly in the limit. As an application we derive new lower bounds for the measurable chromatic number of the Euclidean space in dimensions 10,..., 24, and we give a new proof that it grows exponentially with the dimension.

description: The density-matrix renormalization group (DMRG) applied to transfer matrices allows it to calculate static as well as dynamical properties of one-dimensional quantum systems at finite temperature in the thermodynamic limit. To this end the quantum system is mapped onto a two-dimensional classical system by a Trotter-Suzuki decomposition. Here we discuss two different mappings: The standard mapping onto a two-dimensional lattice with checkerboard structure as well as an alternative mapping introduced by two of us. For the classical system an appropriate quantum transfer matrix is defined which is then treated using a DMRG scheme. As applications, the calculation of thermodynamic properties for a spin-1/2 Heisenberg chain in a staggered magnetic field and the calculation of boundary contributions for open spin chains are discussed. Finally, we show how to obtain real time dynamics from a classical system with complex Boltzmann weights and present results for the autocorrelation function of the XXZ-chain.

description: Critical current density Jc in polycrystalline or granular superconducting material is known to be hysteretic with applied field H due to the focusing of field within the boundary between adjacent grains. This is of concern in the so-called coated conductors wherein superconducting film is grown on a granular, but textured surface of a metal substrate. While previous work has mainly been on Jc determined using induced or magnetization currents, the present work utilizes transport current via an applied potential in strip geometry. It is observed that the effect is not as pronounced using transport current, probably due to a large difference in criterion voltage between the two types of measurements. However, when the films are narrowed by patterning into 200-, 100-, or 80-micron, the hysteresis is clearly seen, because of the forcing of percolation across higher-angle grain boundaries. This effect is compared for films grown on ion-beam-assisted-deposited (IBAD) YSZ substrate and those grown on rolling-assisted-biaxially-textures substrates (RABiTS) which have grains that are about ten times larger. The hysteresis is more pronounced for the latter, which is more likely to have a weak grain boundary spanning the width of the microbridge. This is also of concern to applications in which coated conductors will be striated in order to reduce of AC losses.

description: Massive black holes (BHs) in dwarf galaxies can provide strong constraints on BH seeds, however reliably detecting them is notoriously difficult. High resolution radio observations were recently used to identify accreting massive BHs in nearby dwarf galaxies, with a significant fraction found to be non-nuclear. Here we present the first results of our optical follow-up of these radio-selected active galactic nuclei (AGNs) in dwarf galaxies using integral field unit (IFU) data from Gemini-North. We focus on the dwarf galaxy J1220+3020, which shows no clear optical AGN signatures in its nuclear SDSS spectrum covering the radio source. With our new IFU data, we confirm the presence of an active BH via the AGN coronal line [Fe X] and enhanced [O I] emission coincident with the radio source. Furthermore, we detect broad H$α$ emission and estimate a BH mass of $M_{\rm BH}=10^{4.9}M_\odot$. We compare the narrow emission line ratios to standard BPT diagnostics and shock models. Spatially-resolved BPT diagrams show some AGN signatures, particularly in [O I]/H$α$, but overall do not unambiguously identify the AGN. A comparison of our data to shock models clearly indicates shocked emission surrounding the AGN. The physical model most consistent with the data is an active BH with a radiatively inefficient accretion flow (RIAF) that both photoionizes and shock-excites the surrounding gas. We conclude that feedback is important in radio-selected BHs in dwarf galaxies, and that radio surveys may probe a population of low accretion-rate BHs in dwarf galaxies that cannot be detected through optical surveys alone.

Spatial interference between infectious hotspots: epidemic condensation and optimal windspeed

description: We discuss the effects of spatial interference between two infectious hotspots as a function of the mobility of individuals (wind speed) between the two and their relative degree of infectivity. As long as the upstream hotspot is less contagious than the downstream one, increasing the wind speed leads to a monotonic decrease of the infection peak in the downstream hotspot. Once the upstream hotspot becomes about between twice and five times more infectious than the downstream one, an optimal wind speed emerges, whereby a local minimum peak intensity is attained in the downstream hotspot, along with a local maximum beyond which the beneficial effect of the wind is restored. Since this non-monotonic trend is reminiscent of the equation of state of non-ideal f luids, we dub the above phenomena epidemic condensation. When the relative infectivity of the upstream hotspot exceeds about a factor five, the beneficial effect of the wind above the optimal speed is completely lost: any wind speed above the optimal one leads to a higher infection peak. It is also found that spatial correlation between the two hotspots decay much more slowly than their inverse distance. It is hoped that the above findings may offer a qualitative clue for optimal confinement policies between different cities and urban agglomerates.

The dust-continuum size of TNG50 galaxies at $z=1-5$: a comparison with the distribution of stellar light, stars, dust and H$_2$

description: We present predictions for the extent of the dust-continuum emission of thousands of main-sequence galaxies drawn from the TNG50 simulation between $z=1-5$. To this aim, we couple the radiative transfer code SKIRT to the output of the TNG50 simulation and measure the dust-continuum half-light radius of the modeled galaxies, assuming a Milky Way dust type and a metallicity dependent dust-to-metal ratio. The dust-continuum half-light radius at observed-frame 850 $μ$m is up to $\sim$75 per cent larger than the stellar half-mass radius, but significantly more compact than the observed-frame 1.6 $μ$m (roughly corresponding to H-band) half-light radius, particularly towards high redshifts: the compactness compared to the 1.6 $μ$m emission increases with redshift. This is driven by obscuration of stellar light from the galaxy centres, which increases the apparent extent of 1.6 $μ$m disk sizes relative to that at 850 $μ$m. The difference in relative extents increases with redshift because the observed-frame 1.6 $μ$m emission stems from ever shorter wavelength stellar emission. These results suggest that the compact dust-continuum emission observed in $z>1$ galaxies is not (necessarily) evidence of the buildup of a dense central stellar component. We also find that the dust-continuum half-light radius very closely follows the radius containing half the star formation in galaxies, indicating that single band dust-continuum emission is a good tracer of the location of (obscured) star formation. The dust-continuum emission is more compact than the H2 mass (for galaxies at $z\geq 2$) and the underlying dust mass. The dust emission strongly correlates with locations with the highest dust temperatures, which do not need to be the locations where most H$_2$ and/or dust is located. The presented results are a common feature of main-sequence galaxies.

description: The first measurements of $x_F$-dependent single spin asymmetries of identified charged hadrons, $π^{\pm}$, $K^{\pm}$, and protons, from transversely polarized proton-proton collisions at 62.4 GeV at RHIC are presented. The measurements extend to high-$x_F$ ($|x_F|\sim 0.6$) in both the forward and backward directions.Large asymmetries are seen in the pion and kaon channels. The asymmetries in inclusive $π^{+}$ production, $A_N(π^+)$, increase with $x_F$ from 0 to $\sim$0.25 %at $x_F = 0.6$ and $A_N(π^{-})$ decrease from 0 to $\sim$$-$0.4. Even though $K^-$ contains no valence quarks, observed asymmetries for $K^-$ unexpectedly show positive values similar to those for $K^+$, increasing with $x_F$, whereas proton asymmetries are consistent with zero over the measured kinematic range. Comparisons of the data with predictions of QCD-based models are presented. The flavor dependent single spin asymmetry measurements of identified hadrons allow for stringent tests of theoretical models of partonic dynamics in the RHIC energy regime.

description: Microfinance provides strength to boost the economic activities of low-income earners and thus contributes to eradication of poverty. However, microfinance institutions face stringent competition from commercial banks; the growth of microloan activities of commercial banks may confront microfinance institutions with increased competition for borrowers. In Kenya, the micro finance sector has extremely high competition indicated by the shifting market share and profitability. This study sought to examine the determinants of financial performance of Microfinance banks in Kenya. The study adopted a descriptive research design and used secondary data from 7 Microfinance banks for a period of 5 years from 2011 to 2015. The data collected was analyzed using correlation and regression analysis. The study found a positive and statistically significant relationship between operational efficiency, capital adequacy, firm size and financial performance of microfinance banks in Kenya. However, the study found an insignificant negative relationship between liquidity risk, credit risk and financial performance of microfinance banks in Kenya. The study concluded that there is direct relationship between operational efficiency, capital adequacy, firm size and financial performance of microfinance banks in Kenya.

description: We have entered a new era where integral-field spectroscopic surveys of galaxies are sufficiently large to adequately sample large-scale structure over a cosmologically significant volume. This was the primary design goal of the SAMI Galaxy Survey. Here, in Data Release 3 (DR3), we release data for the full sample of 3068 unique galaxies observed. This includes the SAMI cluster sample of 888 unique galaxies for the first time. For each galaxy, there are two primary spectral cubes covering the blue (370-570nm) and red (630-740nm) optical wavelength ranges at spectral resolving power of R=1808 and 4304 respectively. For each primary cube, we also provide three spatially binned spectral cubes and a set of standardized aperture spectra. For each galaxy, we include complete 2D maps from parameterized fitting to the emission-line and absorption-line spectral data. These maps provide information on the gas ionization and kinematics, stellar kinematics and populations, and more. All data are available online through Australian Astronomical Optics (AAO) Data Central.

description: Η μελέτη αυτή διερευνά τη μαθησιακή επάρκεια παιδιών προσχολικής ηλικίας (προνήπια – νήπια), τα οποία αντιμετωπίζουν προβλήματα λόγου. Εκκινεί από την υπόθεση ότι, όταν παιδιά προσχολικής ηλικίας εμφανίζουν προβλήματα λόγου, αναμένεται να επηρεαστεί συνολικά η μαθησιακή τους επάρκεια. Οι διαταραχές στο λόγο του παιδιού στην προσχολική ηλικία, συνήθως, στη σχολική ηλικία μετεξελίσσονται σε μαθησιακές δυσκολίες. Για τη διερεύνηση της υπόθεσής μας χρησιμοποιήσαμε το κριτήριο μαθησιακής – γνωστικής επάρκειας DTLA – P:3. Στην έρευνα συμμετείχαν 120 παιδιά προσχολικής και πρώτης σχολικής ηλικίας. Τα ευρήματα της έρευνας επιβεβαιώνουν την αρχική μας υπόθεση. Επιπλέον, διαπιστώσαμε ότι η μαθησιακή επάρκεια των παιδιών επηρεάζεται ακόμη περισσότερο με την είσοδό τους στο σχολείο.
description: The subject of the present Thesis is the learning competence of preschool children with language difficulties. Our working hypothesis was that learning competence would be affected in children who have language difficulties. Language difficulties during preschool age, at school age are usually expected to grow into learning disabilities. To investigate our assumption we used the Detroit Test of Learning Aptitude (DTLA – P: 3). We tested through DTLA – P: 3 120 preschool and school age children. The findings of our research confirmed the working hypothesis. Furthermore we noted that children’s learning competence is affected even more when they enter school (first – grade).
