Impact of reverberation in flared accretion discs on temporal characteristics of X-ray binaries
Creators: name: Poutanen, Juri
Publisher: name: arXiv
Year: 2001
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Observations suggest that accretion discs in many X-ray binaries are likely flared. An outer edge of the disc intercepts radiation from the central X-ray source. Part of that radiation is absorbed and reemitted in the optical/UV spectral ranges. However, a large fraction of that radiation is reflected and appears in the broad-band X-ray spectrum as a Compton reflection bump. This radiation is delayed and variability is somewhat smeared compared with the intrinsic X-ray radiation. We compute response functions for flat and flared accretion discs and for isotropic and anisotropic X-ray sources. A simple approximation for the response function which is valid in the broad range of the disc shapes and inclinations, inner and outer radii, and the plasma bulk velocity is proposed. We also study the impact of the X-ray reprocessing on temporal characteristics of X-ray binaries such as the power spectral density, auto- and cross-correlation functions, and time/phase lags. We propose a reprocessing model which explains the secondary peaks in the phase lag Fourier spectra observed in Cyg X-1 and other Galactic black hole sources. The position of the peaks could be used to determine the size of the accretion disc.

description: User independent emotion recognition with large scale physiological signals is a tough problem. There exist many advanced methods but they are conducted under relatively small datasets with dozens of subjects. Here, we propose Res-SIN, a novel end-to-end framework using Electrodermal Activity(EDA) signal images to classify human emotion. We first apply convex optimization-based EDA (cvxEDA) to decompose signals and mine the static and dynamic emotion changes. Then, we transform decomposed signals to images so that they can be effectively processed by CNN frameworks. The Res-SIN combines individual emotion features and external emotion benchmarks to accelerate convergence. We evaluate our approach on the PMEmo dataset, the currently largest emotional dataset containing music and EDA signals. To the best of author's knowledge, our method is the first attempt to classify large scale subject-independent emotion with 7962 pieces of EDA signals from 457 subjects. Experimental results demonstrate the reliability of our model and the binary classification accuracy of 73.65% and 73.43% on arousal and valence dimension can be used as a baseline.

description: Every major city in America is experiencing urban redevelopment to sustain population growth, yet the related impacts of a changing landscape disproportionately harm Black low-income communities. Rising property values and displacement are a few factors that may contribute to quantifiable health disparities among racial groups. However, there is a need for more research that explains the relationship between displacement and specific health outcomes, especially in the context of the declining Black population in east Austin. This thesis seeks to enhance our understanding of the negative impacts of urban redevelopment on Black communities via two methods: a systematic literature review on metropolitan areas across the country and a case study on east Austin, Texas. The literature review characterizes twenty-seven sources, and findings indicate that stress, anxiety, and increased risk for cardiovascular disease appear to be prominent health implications due to exacerbated financial burdens, social pressures, and reduced access to vital services and fresh food. The stress associated with displacement may have intergenerational implications and could contribute to known health disparities in hypertension and diabetes. The case study on east Austin supports the literature review findings by mapping reduced access to healthcare services and fresh food markets external to gentrifying areas. Understanding the roots of health disparities consequential to urban redevelopment can help improve urban planning and policy to better address the needs of those harmed by gentrification.

description: Spontaneous isopeptide bond formation, a stabilizing posttranslational modification that can be found in gram-positive bacterial cell surface proteins, has previously been used to develop a peptide-peptide ligation technology that enables the polymerization of tagged-proteins catalyzed by SpyLigase. Here we adapted this technology to establish a novel modular antibody labeling approach which is based on isopeptide bond formation between two recognition peptides, SpyTag and KTag. Our labeling strategy allows the attachment of a reporting cargo of interest to an antibody scaffold by fusing it chemically to KTag, available via semi-automated solid-phase peptide synthesis (SPPS), while equipping the antibody with SpyTag. This strategy was successfully used to engineer site-specific antibody-drug conjugates (ADCs) that exhibit cytotoxicities in the subnanomolar range. Our approach may lead to a new class of antibody conjugates based on peptide-tags that have minimal effects on protein structure and function, thus expanding the toolbox of site-specific antibody conjugation.

description: It has been experimentally established that the occurrence of charge density waves is a common feature of various under-doped cuprate superconducting compounds. The observed states, which are often found in the form of bond density waves (BDW), often occur in a temperature regime immediately above the superconducting transition temperature. Motivated by recent optical experiments on superconducting materials, where it has been shown that optical irradiation can transiently improve the superconducting features, here, we propose a new approach for the enhancement of superconductivity by the targeted destruction of the BDW order. Since BDW states are usually found in competition with superconductivity, suppression of the BDW order enhances the tendency of electrons to form Cooper pairs after reaching a steady-state. By investigating the optical coupling of gapless, collective fluctuations of the BDW modes, we argue that the resonant excitation of these modes can melt the underlying BDW order parameter. We propose an experimental setup to implement such an optical coupling using 2D plasmon-polariton hybrid systems.

description: Tuberculosis control in developing regions with apparent low incidence, like the low-income Mexican state of Michoacán, with mean annual incidence rates below 10/100,000 inhabitants, requires knowledge of the actual behavior of the disease. This can be determined using an epidemiological profile at sub-regional level, allowing disclosure of the clinical and social factors that may be hampering efforts to control tuberculosis. In this work, a detailed epidemiological profile was outlined using data of all new monthly cases registered in the National System of Epidemiological Surveillance Database for Michoacán municipalities from 2000 to 2012. Cases were grouped by gender and age, and sociodemographic data were obtained both from the National Institute of Statistics and Geography and from the United Nations Development Programme. Correlations were calculated by Chi-square, Mann-Whitney U, and Kruskal-Wallis H tests. We observed no statistically significant differences between notification rates for the years 2000, 2005 and 2010 (χ2 = 0.222, p = 0.895). The percentage of cases is similar between all age groups older than 15, while some regions had low notification rates but high proportions of pediatric cases. Higher proportions of cases of extrapulmonary tuberculosis were observed in municipalities in northern Michoacán. No correlation was found between municipal Human Development Index values and municipal notification rates. Michoacán is undergoing an epidemiological transition with three regions having different epidemiological profiles and particular needs for effective prevention and containment of tuberculosis. Our work shows the importance of the spatial scale of epidemiological profiles for determining specific regional needs of surveillance and containment.

description: A closed form expression for multiplicity-free quantum 6-j symbols (MFS) was proposed in arXiv:1302.5143 for symmetric representations of $U_q(sl_N)$, which are the simplest class of multiplicity-free representations. In this paper we rewrite this expression in terms of q-hypergeometric series ${}_4Φ_3$. We claim that it is possible to express any MFS through the 6-j symbol for $U_q(sl_2)$ with a certain factor. It gives us a universal tool for the extension of various properties of the quantum 6-j symbols for $U_q(sl_2)$ to the MFS. We demonstrate this idea by deriving the asymptotics of the MFS in terms of associated tetrahedron for classical algebra $U(sl_N)$. Next we study MFS symmetries using known hypergeometric identities such as argument permutations and Sears' transformation. We describe symmetry groups of MFS. As a result we get new symmetries, which are a generalization of the tetrahedral symmetries and the Regge symmetries for N = 2.

description: Correlations between black holes and their host galaxies provide insight into what drives black hole-host co-evolution. We use the Meraxes semi-analytic model to investigate the growth of black holes and their host galaxies from high redshift to the present day. Our modelling finds no significant evolution in the black hole-bulge and black hole-total stellar mass relations out to a redshift of 8. The black hole-total stellar mass relation has similar but slightly larger scatter than the black hole-bulge relation, with the scatter in both decreasing with increasing redshift. In our modelling the growth of galaxies, bulges and black holes are all tightly related, even at the highest redshifts. We find that black hole growth is dominated by instability-driven or secular quasar-mode growth and not by merger-driven growth at all redshifts. Our model also predicts that disc-dominated galaxies lie on the black hole-total stellar mass relation, but lie offset from the black hole-bulge mass relation, in agreement with recent observations and hydrodynamical simulations.

Submarine landforms and past ice flow in the Krossfjorden system, northwest Svalbard
Creators: name: Burton, David
Publisher: name: Apollo - University of Cambridge Repository
Year: 2013

description: Very high-resolution swath-bathymetric data, acquired by the Norwegian Hydrographic Service, have been analysed to investigate submarine landforms and their implications for the dynamics and extent of past ice flow in the whole of the Krossfjorden system, northwest Svalbard. The results from this study confirm that ice extended out of the Krossfjorden system (to the shelf edge west of Svalbard) during the Late Weichselian glacial maximum. They also improve the understanding of the relative chronology of retreat through Krossfjorden, which represents the outer part of the fjord system under study. Two transverse ridges were the only ice-marginal features present within Krossfjorden proper, indicating a relatively rapid ice retreat from the continental shelf to the shallower inner fjords of the Krossfjorden system. This retreat was part of the Late Weichselian deglaciation of the northwestern part of the Svalbard-Barents Sea ice sheet. The bathymetric data from the innermost fjords and bays represent the advance and subsequent retreat of ice during the period known as the Little Ice Age, when ice on Svalbard reached a recent maximum about 100 years ago. These advances of the five tidewater glaciers in the Krossfjorden system varied from 2.3 to 5 km, with retreat rates of about 30 to 40 m a-1 from 1910 to 1966 and 10 to 45 m a-1 from 1966 to the present. This variation in retreat rate is attributed to local differences in glacier drainage-basin size, fjord depth and the presence of bedrock outcrops that provided pinning-points during retreat. The very recent deposition of these submarine landforms and the detail in the swath-bathymetric data (including small transverse ridges that in some cases represent annual glacier-terminus positions) have made it possible to produce descriptions and interpretations of the landforms, and to infer the dynamics and retreat rate of ice, at a higher resolution than elsewhere in the Svalbard archipelago.

description: We point out that different choices of Gliozzi-Scherk-Olive (GSO) projections in superstring theory can be conveniently understood by the inclusion of fermionic invertible phases, or equivalently topological superconductors, on the worldsheet. This allows us to find that the unoriented Type $\rm 0$ string theory with $Ω^2=(-1)^{\sf f}$ admits different GSO projections parameterized by $n$ mod 8, depending on the number of Kitaev chains on the worldsheet. The presence of $n$ boundary Majorana fermions then leads to the classification of D-branes by $KO^n(X)\oplus KO^{-n}(X)$ in these theories, which we also confirm by the study of the D-brane boundary states. Finally, we show that there is no essentially new GSO projection for the Type $\rm I$ worldsheet theory by studying the relevant bordism group, which classifies corresponding invertible phases. This paper provides the details for the results announced in the letter \cite{Kaidi:2019pzj}.

Legend and landscape: convergence of oral and scientific traditions with special reference to the Yukon territory, Canada
Creators: name: Cruikshank, Julia M.
Publisher: name: Apollo - University of Cambridge Repository
Year: 1980

description: The paper examines two distinct intellectual traditions in the north, Native oral tradition and western scientif~c research. It begins by discussing my own anthropological field research in the southern Yukon Territory, Canada, the present interest of natural scientists in oral tradition, and the cultural context within which the narratives should be viewed. It then looks at oral tradition and western science as contrasting theoretical frameworks and discusses the strengths and limitations of each. With this background, examples of 'convergence' of the two traditions in the southern Yukon are discussed. Oral traditions about glacier movement and impounded lakes, climatic fluctuations, geography and geology, fauna and flora, and prehistory are compared with present day scientific research about the same phenomena. Scientific interest in oral narrative elsewhere in the circum~ polar north is summarized. The suggestion emerges that in combination the two approaches can provide a broader perspective on the natural environment than can either by itself, particularly if lin guistic categories used by Native speakers can be corr elated with scientific knowled ge of the same phenomena. Oral history and lin guistic research may have a con~ribution to make to an 'anthropology of natural history'. Oral tradition must be seen as a distinctive intellectual tradition, not simply as an adjunct to western science.

description: This study investigates the oxide formation behaviour and mechanical properties of oxide-dispersion-strengthened (ODS) CoCrFeMnNi high-entropy alloy (HEA) matrix composites produced via powder metallurgy. Grain boundary strengthening, solid solution hardening, and precipitation hardening were controlled by varying the duration of mechanical milling and heat treatment durations. The grain size decreased significantly upon milling and it increased to the range of hundreds of nanometres with the heat treatment. Although ex situ-added Y2O3 nanoparticles were uniformly dispersed in the HEA matrix regardless of the milling duration and heat treatment time, different types of in situ oxides, such as Cr- and Mn-oxides, were formed during the heat treatment. Longer milling times led to more crystal defects (e.g. grain boundaries and dislocations) and stored energy in the HEA matrix, thereby stimulating second phase precipitation and oxide formation. Under optimal conditions, the ODS-HEA composites exhibited a good balance between yield strength and elongation in compression.

Two-phase percolation in texturally equilibrated porous media

Subjects: Textural equilibrium
Porous media

description: Texturally equilibrated porous media are an important part of many natural systems of interest including subsurface salt formations, glacier systems, and partially molten melt systems. The processes that create this type of medium and the specific pore space geometry are both unique aspects of texturally equilibrated porous media that are different from conventional rock geometries studied in petroleum engineering. Single phase flow and creation of these pore spaces has been studied in the past; although in reality, multiple fluid phases are likely to be present during both their creation and flow within. As a first step in exploring this problem, two-phase flow simulations through texturally equilibrated pore spaces remained the focus of this study. First, a fully open-source lattice-Boltzmann method simulation workflow was developed to produce relative permeability curves, capillary pressure curves, and 3D along with 4D visualizations. Next, the developed workflow was utilized to run the first two-phase flow simulations in texturally equilibrated porous media within the context of planetary core formation. Finally, a morphological drainage tool was used to supplement the two-phase flow simulations and to compare twelve different texturally equilibrated geometries. The unique geometry of texturally equilibrated pore spaces includes sharp corners and long pore throats. The geometry was observed to alter flow behavior from what is typically observed in conventional types of porous media, and the sharp corners tended to trap the wetting phase fluid in connected, tube-like paths. Overall, these results can be used to make further insights in the variety of application areas where texturally equilibrated porous media can be found
The Role of 5’ hox13 Genes in Danio rerio (Zebrafish) Caudal Fin Ray/Joint Development and Regeneration

Fin ray

description: Zebrafish are part of the teleost infraclass (bony fish) of the ray-finned fish. Like other teleosts, zebrafish possess the ability to regenerate most tissues, including their fins. Zebrafish fins contain segmented bony fin rays that longitudinally span the fin. The segments of fin ray are separated by fibrous joints at regularly spaced intervals providing segmentation and flexibility for the fin. Based on gene expression and changes in cell morphology, joint cell differentiation during development and regeneration proceeds through three stages: presumptive joint, joint-forming, and mature joint cells. Our lab has shown that new joint formation correlates with the upregulation of 5’ hoxa gene, hoxa13a. The hox genes encode transcription factors important for patterning in development. In mice, phenotypes resulting from loss- and gain-of-function mutations in Hox genes have revealed that the spatiotemporal expression of these genes is critical for the correct morphogenesis of the limb, a homologous structure to the fin. The first experiments in this thesis use the NTR/MTZ mechanism to partially ablate hoxa13a-expressing cells in the joints and blastema of the regenerating caudal fin. Partial ablation of the hoxa13a-expressing cells results in shorter bone segments following regeneration of the fin. This experiment draws the conclusion that hoxa13a-expressing cells are involved in the regulation of segment length. To examine the function of the 5’ hoxa/d genes in zebrafish, our lab created CRISPR/Cas9 mutations that inactivate hoxa13a, hoxa13b, and hoxd13a. The triple mutants created through serial breeding, show fin-specific defects in the formation and patterning of joints, as well as general defects in the morphology of the ray and in the actinotrichia, collagenous fibres found at the distal edge of the fin. Overall, our data suggest that hox13 genes are necessary for joint formation and proper fin ray growth. With further phenotypic and genotypic analyses our lab proposes that the dosage of hox13 alleles is responsible for anomalies in fin ray formation found in hox13 mutants.

description: We study to unify soliton systems, KdV/mKdV/sinh-Gordon, through SO(2,1) $\cong$ GL(2,$\mathbb R$) $\cong$ Möbius group point of view, which might be a keystone to exactly solve some special non-linear differential equations. If we construct the $N$-soliton solutions through the KdV type Bäcklund transformation, we can transform different KdV/mKdV/sinh-Gordon equations and the Bäcklund transformations of the standard form into the same common Hirota form and the same common Bäcklund transformation except the equation which has the time-derivative term. The difference is only the time-dependence and the main structure of the $N$-soliton solutions has same common form for KdV/mKdV/sinh-Gordon systems. Then the $N$-soliton solutions for the sinh-Gordon equation is obtained just by the replacement from KdV/mKdV $N$-soliton solutions. We also give general addition formulae coming from the KdV type Bäcklund transformation which plays not only an important role to construct the trigonometric/hyperbolic $N$-soliton solutions but also an essential role to construct the elliptic $N$-soliton solutions. In contrast to the KdV type Bäcklund transformation, the well-known mKdV/sinh-Gordon type Bäcklund transformation gives the non-cyclic symmetric $N$-soliton solutions. We give an explicit non-cyclic symmetric 3-soliton solution for KdV/mKdV/sinh-Gordon equations.

description: The presence of OH (1720 MHz) masers, and the absence of counterparts at 1665/1667 MHz has proved to be a clear diagnostic of shocked molecular gas associated with Galactic supernova remnants. This suggests that shocked molecular gas should be associated with the OH (1720 MHz) masers that have been detected in the circumnuclear disk (CND) and Sgr A East at the Galactic center. In order to test this hypothesis, we observed the H$_2$ 1--0 S(1) and Br $γ$ lines using NICMOS on the HST and UNSWIRF on the AAT, near the regions where OH (1720 MHz) masers are detected in the CND and Sgr A East. We present the distribution of H$_2$ in the North and South lobes of the CND and in Sgr A East. H$_2$ emission accompanies almost all of the maser spots detected at the Galactic center. In particular, we find a striking filamentary structure near the Northwest of the CND and evidence that shocked molecular gas is associated with the 70 \kms molecular cloud at the Galactic center. We argue that the emission from the CND could arise in gas heated by the dissipation of the random motion of clumps by collisions or the dissipation of turbulence in a more homogeneous medium. In addition, highly red-shifted gas of up to 140 \kms\ close to the eastern edge of the Sgr A East shell is detected. These observations combined with OH (1720 MHz) results suggest that the H$_2$ gas is shocked and accelerated by the expansion of Sgr A East into the 50 and the 70 \kms cloud and into the lobes of the CND.

description: Tree-level scattering amplitudes for a scalar particle coupled to an arbitrary number N of photons and a single graviton are computed. We employ the worldline formalism as the main tool to compute the irreducible part of the amplitude, where all the photons and the graviton are directly attached to the scalar line, then derive a tree replacement rule to construct the reducible parts of the amplitude which involve irreducible pure N-photon two-scalar amplitudes where one photon line emits the graviton. We test our construction by verifying the on-shell gauge and diffeomorphism Ward identities, at arbitrary N.

description: We study a non local version of the sine-Gordon model connected to a many-body system with backward and umklapp scattering processes. Using renormalization group methods we derive the flow equations for the couplings and show how non locality affects the gap in the spectrum of charge-density excitations. We compare our results with previous predictions obtained through the self-consistent harmonic approximation.

description: Um globalen Herausforderungen wie der ökologischen Krise zu begegnen und an einer nachhaltigen Entwicklung mitzuwirken, benötigen Lernende ein grundlegendes Verständnis ökologischer Prinzipien und Wirkungszusammenhänge. Im Unterrichtsfach Biologie sollen hierfür wesentliche ökologische Konzepte vermittelt werden. Gleichzeitig hat sich gezeigt, dass Lernende trotz oft vorausgegangenem Unterricht häufig Schwierigkeiten haben, relevante Aspekte wie z. B. die essentielle Bedeutung von Pflanzen in Ökosystemen angemessen einzuschätzen. Es stellt sich die Frage, wie sich bei Lernenden das Verständnis ökologischer Konzepte entwickelt und wie es wirksam gefördert werden kann. Zur Beantwortung dieser Frage wurden im Rahmen einer Querschnittstudie wurden Schülerinnen und Schüler der Sekundarstufe I aus unterschiedlichen Klassenstufen zu ihren Vorstellungen und Denkmustern zu wesentlichen ökologischen Konzepten befragt (N = 294). Darüber hinaus wurden im Rahmen einer Wirksamkeitsstudie die Effekte eines Waldschulheimaufenthalts auf die Entwicklung eines Verständnisses der hier fokussierten ökologischen Konzepte getestet (N = 52). Es zeigte sich u. a., dass sich die Vorstellungen der Lernenden zu Stoffkreisläufen im Laufe der Sekundarstufe I deutlich in Richtung fachlich gültiger Vorstellungen veränderten. Durch den Waldschulheimaufenthalt konnten lediglich einzelne Aspekte gefördert werden, z. B. die Artenkenntnis von Pflanzen des Waldes. Die Ergebnisse werden in Hinblick auf die Wirkung von Biologieunterricht und Entwicklung von Lernangeboten hinsichtlich der Förderung nachhaltigkeitsrelevanten ökologischen Wissens diskutiert.

Techniques for Inverted Index Compression

description: The data structure at the core of large-scale search engines is the inverted index, which is essentially a collection of sorted integer sequences called inverted lists. Because of the many documents indexed by such engines and stringent performance requirements imposed by the heavy load of queries, the inverted index stores billions of integers that must be searched efficiently. In this scenario, index compression is essential because it leads to a better exploitation of the computer memory hierarchy for faster query processing and, at the same time, allows reducing the number of storage machines. The aim of this article is twofold: first, surveying the encoding algorithms suitable for inverted index compression and, second, characterizing the performance of the inverted index through experimentation.

description: We consider the escape probability of a photon emitted from the innermost stable circular orbit (ISCO) of a rapidly rotating black hole. As an isotropically emitting light source on a circular orbit reduces its orbital radius, the escape probability of a photon emitted from it decreases monotonically. The escape probability evaluated at the ISCO also decreases monotonically as the black hole spin increases. When the dimensionless Kerr parameter $a$ is at the Thorne limit $a=0.998$, the escape probability from the ISCO is $58.8\%$. In the extremal case $a=1$, even if the orbital radius of the light source is arbitrarily close to the ISCO radius, which coincides with the horizon radius, the escape probability remains at $54.6\%$. We also show that such photons that have escaped from the vicinity of the horizon reach infinity with sufficient energy to be potentially observed because Doppler blueshift due to relativistic beaming can overcome the gravitational redshift. Our findings indicate that signs of the near-horizon physics of a rapidly rotating black hole will be detectable on the edge of its shadow.

description: This thesis focusses on the properties of, and relationships between, several fundamental objects arising from critical physical models. In particular, we consider Schramm--Loewner evolutions, the Gaussian free field, Liouville quantum gravity and the Brownian continuum random tree. We begin by considering branching diffusions in a bounded domain $D\subset \R^d$, in which particles are killed upon hitting the boundary $\partial D$. It is known that such a system displays a phase transition in the branching rate: if it exceeds a critical value, the population will no longer become extinct almost surely. We prove that at criticality, under mild assumptions on the branching mechanism and diffusion, the genealogical tree associated with the process will converge to the Brownian CRT. Next, we move on to study Gaussian multiplicative chaos. This is the rigorous framework that allows one to make sense of random measures built from rough Gaussian fields, and again there is a parameter associated with the model in which a phase transition occurs. We prove a uniqueness and convergence result for approximations to these measures at criticality. From this point onwards we restrict our attention to two-dimensional models. First, we give an alternative, ``non-Gaussian" construction of Liouville quantum gravity (a special case of Gaussian multiplicative chaos associated with the 2-dimensional Gaussian free field), that is motivated by the theory of multiplicative cascades. We prove that the Liouville (GMC) measures associated with the Gaussian free field can be approximated using certain sequences of ``local sets" of the field. This is a particularly natural construction as it is both local and conformally invariant. It includes the case of nested $\CLE_4$, when it is coupled with the GFF as its set of ``level lines". Finally, we consider this level line coupling more closely, now when it is between $\SLE_4$ and the GFF. We prove that level lines can be defined for the GFF with a wide range of boundary conditions, and are given by $\SLE_4$-type curves. As a consequence, we extend the definition of $\SLE_4(\rho)$ to the case of a continuum of force points.

description: We report the first measurement of inclusive antiproton production at mid-rapidity in Au+Au collisions at 130 GeV by the STAR experiment at RHIC. The antiproton transverse mass distributions in the measured transverse momentum range of 0.25 < pT < 0.95 GeV/c are found to fall less steeply for more central collisions. The extrapolated antiproton rapidity density is found to scale approximately with the negative hadron multiplicity density.
