description: In this work we revisit the steady state, spherically symmetric gas accretion problem from the non-relativistic regime to the ultra-relativistic one. We first perform a detailed comparison between the Bondi and Michel models, and show how the mass accretion rate in the Michel solution approaches a constant value as the fluid temperature increases, whereas the corresponding Bondi value continually decreases, the difference between these two predicted values becoming arbitrarily large at ultra-relativistic temperatures. Additionally, we extend the Michel solution to the case of a fluid with an equation of state corresponding to a monoatomic, relativistic gas. Finally, using general relativistic hydrodynamic simulations, we study spherical accretion onto a rotating black hole, exploring the influence of the black hole spin on the mass accretion rate, the flow morphology and characteristics, and the sonic surface. The effect of the black hole spin becomes more significant as the gas temperature increases and as the adiabatic index $γ$ stiffens. For an ideal gas in the ultra-relativistic limit ($γ=4/3$), we find a reduction of 10 per cent in the mass accretion rate for a maximally rotating black hole as compared to a non-rotating one, while this reduction is of up to 50 per cent for a stiff fluid ($γ=2$).

Star formation through gravitational collapse and competitive accretion

description: Competitive accretion, a process to explain the origin of the IMF, occurs when stars in a common gravitational potential accrete from a distributed gaseous component. We show that concerns recently raised on the efficiency of competitive accretion are incorrect as they use globally averaged properties which are inappropriate for the detailed physics of a forming stellar cluster. A full treatment requires a realistic treatment of the cluster potential, the distribution of turbulent velocities and gas densities. Accreting gas does not travel at the global virial velocity of the system due to the velocity-sizescale relation inherent in turbulent gas and due to the lower velocity dispersion of small-N clusters in which much of the accretion occurs. Stars located in the gas-rich centres of such systems initially accrete from low relative velocity gas attaining larger masses before needing to accrete the higher velocity gas. Stars not in the centres of such potentials, or that enter the cluster later when the velocity dispersion is higher, do not accrete significantly and thus retain their low-masses. In competitive accretion, most stars do not continue to accrete significantly such that their masses are set from the fragmentation process. It is the few stars which continue to accrete that become higher-mass stars. Competitive accretion is therefore likely to be responsible for the formation of higher-mass stars and can explain the mass distribution, mass segregation and binary frequency of these stars. Global kinematics of competitive accretion models include large-scale mass infall, with mean inflow velocities of order 0.5 km/s at scales of 0.5 pc, but infall signatures are likely to be confused by the large tangential velocities and the velocity dispersion present.

description: In this paper we calculate the average number of cliques in random scale-free networks. We consider first the hidden variable ensemble and subsequently the Molloy Reed ensemble. In both cases we find that cliques, i.e. fully connected subgraphs, appear also when the average degree is finite. This is in contrast to what happens in Erdös and Renyi graphs in which diverging average degree is required to observe cliques of size $c>3$. Moreover we show that in random scale-free networks the clique number, i.e. the size of the largest clique present in the network diverges with the system size.

description: We present a suite of baryonic cosmological zoom-in simulations of self-interacting dark matter (SIDM) haloes within the ``Feedback In Realistic Environment'' (FIRE) project. The three simulated haloes have virial masses of $\sim 10^{12}\, \text{M}_\odot$ at $z=0$, and we study velocity-independent self-interaction cross sections of 1 and 10 ${\rm cm^2 \, g^{-1}}$. We study star formation rates and the shape of dark matter density profiles of the parent haloes in both cold dark matter (CDM) and SIDM models. Galaxies formed in the SIDM haloes have higher star formation rates at $z\leq1$, resulting in more massive galaxies compared to the CDM simulations. While both CDM and SIDM simulations show diverse shape of the dark matter density profiles, the SIDM haloes can reach higher and more steep central densities within few kpcs compared to the CDM haloes. We identify a correlation between the build-up of the stars within the half-mass radii of the galaxies and the growth in the central dark matter densities. The thermalization process in the SIDM haloes is enhanced in the presence of a dense stellar component. Hence, SIDM haloes with highly concentrated baryonic profiles are predicted to have higher central dark matter densities than the CDM haloes. Overall, the SIDM haloes are more responsive to the presence of a massive baryonic distribution than their CDM counterparts.

description: Turbulence is a key element of the dynamics of astrophysical fluids, including those of interstellar medium, clusters of galaxies and circumstellar regions. Turbulent motions induce Doppler shifts of observable emission and absorption lines and this motivates studies of turbulence using precision spectroscopy. We provide high resolution numerical testing of the two promising techniques, namely, Velocity Channel Analysis and Velocity Coordinate Spectrum. We obtain an expression for the shot noise that the discretization of the numerical data entails and successfully test it. We show that numerical resolution required for recovering the underlying turbulent spectrum from observations depend on the spectral index of velocity fluctuations. Thus the low resolution testing may be misleading.

description: Current gate-based quantum computers have the potential to provide a computational advantage if algorithms use quantum hardware efficiently. To make combinatorial optimization more efficient, we introduce the Filtering Variational Quantum Eigensolver (F-VQE) which utilizes filtering operators to achieve faster and more reliable convergence to the optimal solution. Additionally we explore the use of causal cones to reduce the number of qubits required on a quantum computer. Using random weighted MaxCut problems, we numerically analyze our methods and show that they perform better than the original VQE algorithm and the Quantum Approximate Optimization Algorithm (QAOA). We also demonstrate the experimental feasibility of our algorithms on a Honeywell trapped-ion quantum processor.

Polarised infrared emission from X-ray binary jets

Year: 2008
Subjects: subject: Astrophysics (astro-ph)

description: Near-infrared (NIR) and optical polarimetric observations of a selection of X-ray binaries are presented. The targets were observed using the Very Large Telescope and the United Kingdom Infrared Telescope. We detect a significant level (3 sigma) of linear polarisation in four sources. The polarisation is found to be intrinsic (at the > 3 sigma level) in two sources; GRO J1655-40 (~ 4-7% in H and Ks-bands during an outburst) and Sco X-1 (~ 0.1-0.9% in H and K), which is stronger at lower frequencies. This is likely to be the signature of optically thin synchrotron emission from the collimated jets in these systems, whose presence indicates a partially-ordered magnetic field is present at the inner regions of the jets. In Sco X-1 the intrinsic polarisation is variable (and sometimes absent) in the H and K-bands. In the J-band (i.e. at higher frequencies) the polarisation is not significantly variable and is consistent with an interstellar origin. The optical light from GX 339-4 is also polarised, but at a level and position angle consistent with scattering by interstellar dust. The other polarised source is SS 433, which has a low level (0.5-0.8%) of J-band polarisation, likely due to local scattering. The NIR counterparts of GRO J0422+32, XTE J1118+480, 4U 0614+09 and Aql X-1 (which were all in or near quiescence) have a linear polarisation level of < 16% (3 sigma upper limit, some are < 6%). We discuss how such observations may be used to constrain the ordering of the magnetic field close to the base of the jet in such systems.

description: Context: Sunspot penumbrae harbor highly structured magnetic fields and flows. The moving flux tube model offers an explanation for several observed phenomena, e.g. the Evershed effect and bright penumbral grains. Aims: A wealth of information can be extracted from spectropolarimetric observations. In order to deduce the structure of the magnetic field in sunspot penumbrae, detailed forward modeling is necessary. On the one hand, it gives insight into the sensitivity of various spectral lines to different physical scenarios. On the other hand, it is a very useful tool to guide inversion techniques. In this work, we present a generalized 3D geometrical model that embeds an arbitrarily shaped flux tube in a stratified magnetized atmosphere. Methods: The new semi-analytical geometric model serves as a frontend for a polarized radiative transfer code. The advantage of this model is that it preserves the discontinuities of the physical parameters across the flux tube boundaries. This is important for the detailed shape of the emerging Stokes Profiles and the resulting net circular polarization (NCP). Results: (a) The inclination of downflows in the outer penumbra must be shallower than approximately 15 degrees. (b) Observing the limb-side NCP of sunspots in the Fe I 1564.8 nm line offers a promising way to identify a reduced magnetic field strength in flow channels. (c) The choice of the background atmosphere can significantly influence the shape of the Stokes profiles, but does not change the global characteristics of the resulting NCP curves for the tested atmospheric models.

description: Germacrene B is an abundant volatile metabolite in the essential oils of several plants that have major pharmaceutical and ecological interest (Araujo et al., 2003; Eom et al., 2006; Salido et al., 2002; Singh et al., 2006). The synthase that leads to the production of germacrene B in trichomes was isolated and characterized in 2008 from the plant Cistus creticus subsp. creticus by Vasiliki Falara, group of Biotechnology of Pharmaceutical Plants, Laboratory of Pharmacognosy, Department of Pharmaceutical Sciences, Aristotle University of Thessaloniki. The objective of this M.Sc thesis was the isolation and the functional characterization of the germacrene B synthase gene promoter (PRO/GERBS). For this purpose we isolated, sequenced and cloned the DNA region of the above promoter from the plant Cistus creticus. In order to do the qualitative determination of promoter expression, transient transformation in Nicotiana benthamiana plants was conducted and expression was studied using the reporter gene beta-glucuronidase (GUS), which was fused with the promoter. The bioinformatic analysis of the promoter sequence revealed the existence of important cis-elements as well as one transposable element.

All these generators can be obtained by temporal coarse-graining procedures, and we compare different coarse-graining schemes. Similar as for undriven systems, we find that a dynamically adapted coarse-graining time, effectively yielding non-Markovian dynamics by interpolating through a series of different but invididually Markovian solutions, gives the best results among the different coarse-graining schemes, albeit at highest computational cost.

Publisher: name: University of British Columbia

description: This thesis reports methodology that was developed to isolate and enrich intestinal endocrine cell preparations by centrifugal elutriation and short-term culture to enable the study of the regulation of IRGIP secretion at the cellular level. Adherent canine epithelial cell cultures contained ~10% IRGIP cells. The release of IRGIP from these cells was significantly increased by incubation with depolarizing concentrations of K⁺, glucose, somatostatin immunoneutralizing antibody, or GRP, in addition to pharmacological elevations of intracellular cAMP or Ca²⁺. It is concluded that this method provides a means of further investigating the cellular mechanisms controlling GIP release. Enteroendocrine tumor cell lines were also investigated as an alternate source of GIP cells. A cell line derived from intestinal tumors of transgenic mice (STC- 1) was subcloned to produce a cell line with ~30% IRGIP (STC 6-14). HPLC of STC 6-14 extracts indicated that the tumor cell derived IRGIP eluted with synthetic porcine GIP 1-42. Release of IRGIP from STC 6-14 cells; increased in a concentration dependent fashion in response to glucose, was augmented by the addition of somatostatin neutralizing antibody, and attenuated by exogenous somatostatin. Immunoreactive somatostatin (IRSS) release was significantly increased by adding GIP to the incubation medium. It is concluded that this cell line represents a means of rapidly obtaining large numbers of GIP cells, and thus should be useful to investigate stimulus-secretion coupling in the GIP cell. GIP secreted by STC 6-14 cells was metabolized by a serum constituent to biologically inactive GIP 3-42. ¹²⁵I-GIP was purified by HPLC and used as a highly sensitive means to further investigate the degradation of GIP by serum. The removal of the N-terminal dipeptide by serum could be blocked by diprotin A, a competitive inhibitor of dipeptidyl peptidase IV (DPP IV). No GIP 3-42 was produced by incubation of GIP with serum from rats specifically lacking DPP IV. Infusion ¹²⁵I-GIP into rats, followed by HPLC analysis, indicated that 50% was metabolized ¹²⁵I-GIP 3-42 by ~1.5 min. It is concluded that DPP IV is a primary degradative and inactivating enzyme of GIP.

description: We address the phase retrieval problem with errors in the sensing vectors. A number of recent methods for phase retrieval are based on least squares (LS) formulations which assume errors in the quadratic measurements. We extend this approach to handle errors in the sensing vectors by adopting the total least squares (TLS) framework that is used in linear inverse problems with operator errors. We show how gradient descent and the specific geometry of the phase retrieval problem can be used to obtain a simple and efficient TLS solution. Additionally, we derive the gradients of the TLS and LS solutions with respect to the sensing vectors and measurements which enables us to calculate the solution errors. By analyzing these error expressions we determine conditions under which each method should outperform the other. We run simulations to demonstrate that our method can lead to more accurate solutions. We further demonstrate the effectiveness of our approach by performing phase retrieval experiments on real optical hardware which naturally contains both sensing vector and measurement errors.

description: Previous analysis on forecasting theory either assume knowing the true parameters or assume the stationarity of the series. Not much are known on the forecasting theory for nonstationary process with estimated parameters. This paper investigates the recursive least square forecast for stationary and nonstationary processes with unit roots. We first prove that the accumulated forecast mean square error can be decomposed into two components, one of which arises from estimation uncertainty and the other from the disturbance term. The former, of the order of $\log(T)$, is of second order importance to the latter term, of the order T. However, since the latter is common for all predictors, it is the former that determines the property of each predictor. Our theorem implies that the improvement of forecasting precision is of the order of $\log(T)$ when existence of unit root is properly detected and taken into account. Also, our theorem leads to a new proof of strong consistency of predictive least squares in model selection and a new test of unit root where no regression is needed. The simulation results confirm our theoretical findings. In addition, we find that while mis-specification of AR order and under-specification of the number of unit root have marginal impact on forecasting precision, over-specification of the number of unit root strongly deteriorates the quality of long term forecast. As for the empirical study using Taiwanese data, the results are mixed. Adaptive forecast and imposing unit root improve forecast precision for some cases but deteriorate forecasting precision for other cases.

description: The area of domain adaptation has been instrumental in addressing the domain shift problem encountered by many applications. This problem arises due to the difference between the distributions of source data used for training in comparison with target data used during realistic testing scenarios. In this paper, we introduce a novel MultiScale Domain Adaptive YOLO (MS-DAYOLO) framework that employs multiple domain adaptation paths and corresponding domain classifiers at different scales of the recently introduced YOLOv4 object detector to generate domain-invariant features. We train and test our proposed method using popular datasets. Our experiments show significant improvements in object detection performance when training YOLOv4 using the proposed MS-DAYOLO and when tested on target data representing challenging weather conditions for autonomous driving applications.

description: A natural explicit condition is given ensuring that an action of the multiplicative monoid of non-negative reals on a manifold F comes from homotheties of a vector bundle structure on F, or, equivalently, from an Euler vector field. This is used in showing that double (or higher) vector bundles present in the literature can be equivalently defined as manifolds with a family of commuting Euler vector fields. Higher vector bundles can be therefore defined as manifolds admitting certain $\N^n$-grading in the structure sheaf. Consequently, multi-graded (super)manifolds are canonically associated with higher vector bundles that is an equivalence of categories. Of particular interest are symplectic multi-graded manifolds which are proven to be associated with cotangent bundles. Duality for higher vector bundles is then explained by means of the cotangent bundles as they contain the collection of all possible duals. This gives, moreover, higher generalizations of the known `universal Legendre transformation' T*E->T*E*, identifying the cotangent bundles of all higher vector bundles in duality. The symplectic multi-graded manifolds, equipped with certain homological Hamiltonian vector fields, lead to an alternative to Roytenberg's picture generalization of Lie bialgebroids, Courant brackets, Drinfeld doubles and can be viewed as geometrical base for higher BRST and Batalin-Vilkovisky formalisms. This is also a natural framework for studying n-fold Lie algebroids and related structures.

description: Recently, the BESIII Collaboration reported a resonance $Y(2040)$ with $M=2034\pm13\pm9$ MeV and $Γ=234\pm30\pm25$ MeV in the process of $e^+e^-\rightarrowωπ^0$. In addition, new measurements with much higher precision for the $ρ(1900)$ and $ρ(2150)$ states are obtained by the BESIII and BABAR Collaborations. In this work, we perform a systematic study on the mass spectrum of the excited $ρ$ resonances using the modified Godfrey-Isgur model, and the strong decays of $Y(2040)$, $ρ(1900)$, and $ρ(2150)$ within the $^3P_0$ model.We find that $Y(2040)$, $ρ(1900)$, and $ρ(2150)$ can be interpreted as the $ρ(2^3D_1)$, $ρ(3^3S_1)$, and $ρ(4^3S_1)$ states, respectively. Meanwhile, the mass and strong decays of the $ρ(3^3D_1)$ state are predicted as well, which could be helpful to search for this state in future.

description: Θεματική της παρούσας εργασίας αποτελεί ο θεσμός των pacta (συμφώνων) στο Ρωμαϊκό Δίκαιο και η εξέλιξή του στο Βυζαντινό Δίκαιο. Επρόκειτο για έναν πολύ σημαντικό θεσμό του Ρωμαϊκού Ενοχικού Δικαίου που αφορούσε όλες τις άτυπες μη απαγορευμένες από το νόμο συμβάσεις, οι οποίες δεν ήταν αγώγιμες, αλλά γεννούσαν απλώς φυσική ενοχή. Στο πρώτο κεφάλαιο της εργασίας γίνεται ένας εννοιολογικός προσδιορισμός των pacta και ένας διαχωρισμός τους από έναν άλλο σημαντικό θεσμό του Ρωμαϊκού Δικαίου, τα contracta, τα οποία ήταν αγώγιμα. Στο δεύτερο κεφάλαιο της εργασίας γίνεται μια παρουσίαση του θεσμού των pacta στα πλαίσια του Ρωμαϊκού Δικαίου. Πιο συγκεκριμένα, γίνεται αναφορά στα στοιχεία της νομικής φύσης και της νομοτεχνικής υπόστασης του θεσμού, ενώ παράλληλα, παρουσιάζεται η εξέλιξη του θεσμού στο Ρωμαϊκό Δίκαιο και ειδικότερα, μετά την καθιέρωση κάποιων pacta ως αγώγιμων, η διάκρισή τους σε pacta adiecta, pacta praetoria, pacta legitima και pacta nuda. Στο τρίτο κεφάλαιο παρουσιάζεται η εξέλιξη του θεσμού των pacta στο Βυζαντινό Δίκαιο μέσα από αναφορές στο περιεχόμενο των πηγών του και γίνεται μια προσπάθεια εντοπισμού ομοιοτήτων και διαφορών σε σχέση με την εφαρμογή του θεσμού στα πλαίσια του Ρωμαϊκού Δικαίου. Τέλος, στο κεφάλαιο του επιλόγου της εργασίας γίνεται μια αποτίμηση του θεσμού των pacta και παρουσιάζονται κάποια συμπεράσματα και διαπιστώσεις σχετικά με την εφαρμογή αυτού του θεσμού και την εξέλιξή του μέσα στο πέρασμα του χρόνου.
description: The issue of this essay is the institution of pacta in Roman Law and its evolution in Byzantine Law. Pacta was a very important institution in Roman Law of obligations which concerned all the informal - not prohibited by law - contracts, which were not enforceable by action, but would just create natural obligation. In the first part of the essay, there is a definition of pacta and a separation between pacta and another important institution in Roman Law, contracta, which were enforceable by action. In the second part there is a presentation of pacta during Roman Law. In particular there is a reference in the nature of pacta and the legistlative drafting status of the institution as well as a presentation of the evolution of the institution during the period of Roman Law. In particular, after the establishment of some pacta as enforceable by action, all the categories of pacta (pacta adiecta, pacta praetoria, pacta legitima and pacta nuda) are presented one by one. In the third part there is a presentation of pacta in Byzantine Law through references in texts of Byzantine Law and there is an effort to identify similarities and differences between pacta in Roman Law and pacta in Byzantine Law. The essay is completed by an overall assessment of the institution of pacta and the conclusions about the application and the evolution of this institution are presented.

Population Synthesis in the Blue IV: Accurate Model Predictions for Lick Indices and UBV Colors in Single Stellar Populations
Creators: name: Schiavon, Ricardo P.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: [Abridged] We present new model predictions for 16 Lick absorption line indices from Hdelta through Fe5335, and UBV colors for single stellar populations (SPs) with ages ranging between 1 and 15 Gyr, [Fe/H] ranging from -1.3 to +0.3, and variable abundance ratios. We develop a method to estimate mean ages and abundances of Fe, C, N, Mg, and Ca that explores the sensitivity of the various indices to those parameters. When applied to high-S/N Galactic cluster data, the models match the clusters' elemental abundances and ages with high precision. Analyzing stacked SDSS spectra of early-type galaxies brighter than Lstar, we find mean luminosity-weighted ages of the order of ~ 8 Gyr and iron abundances slightly below solar. Abundance ratios, [X/Fe], are higher than solar, and correlate positively with galaxy luminosity. Nitrogen is the element whose abundance correlates the most strongly with luminosity, which seems to indicate secondary enrichment. This result may impose a lower limit of 50-200 Myr to the time-scale of star formation in early-type galaxies. Unlike in the case of clusters, in galaxies bluer Balmer lines yield younger ages than Hbeta. This age discrepancy is stronger for lower luminosity galaxies. We examine four scenarios to explain this trend. The most likely is the presence of small amounts of a young/intermediate-age SP component. Two-component models provide a better match to the data when the mass fraction of the young component is a few %. This result implies that star formation has been extended in early-type galaxies, and more so in less massive galaxies, lending support to the ``downsizing'' scenario. It also implies that SP synthesis models are capable of constraining not only the mean ages of SPs in galaxies, but also their age spread.

Constraining reionization with the first measurement of the cross-correlation between the CMB optical-depth fluctuations and the Compton y-map

description: We propose a new reionization probe that uses cosmic microwave background (CMB) observations; the cross-correlation between fluctuations in the CMB optical depth which probes the integrated electron density, $δτ$, and the Compton $y$-map which probes the integrated electron pressure. This cross-correlation is much less contaminated than the $y$-map power spectrum by late-time cluster contributions. In addition, this cross-correlation can constrain the temperature of ionized bubbles while the optical-depth fluctuations and kinetic SZ effect can not. We measure this new observable using a Planck $y$-map as well as a map of optical-depth fluctuations that we reconstruct from Planck CMB temperature data. We use our measurements to derive a first CMB-only upper limit on the temperature inside ionized bubbles, $T_{\rm b}\lesssim 7.0\times10^5\,$K ($2\,σ$). We also present future forecasts, assuming a fiducial model with characteristic reionization bubble size $R_{\rm b}=5\,$Mpc and $T_{\rm b}=5\times10^4\,$K. The signal-to-noise ratio of the fiducial cross-correlation using a signal dominated PICO-like $y$-map becomes $\simeq7$ with CMB-S4 $δτ$ and $\simeq13$ with CMB-HD $δτ$. For the fiducial model, we predict that the CMB-HD $-$ PICO cross-correlation should achieve an accurate measurement of the reionization parameters; $T_{\rm b}\simeq 49800^{+4500}_{-5100}\,$K and $R_{\rm b}\simeq 5.09^{+0.66}_{-0.79}\,$Mpc. Since the power spectrum of the electron density fluctuations is constrained by the $δτ$ auto spectrum, the temperature constraints should be only weakly model-dependent on the details of the electron distributions and should be statistically representative of the temperature in ionized bubbles during reionization. This cross-correlation could, therefore, become an important observable for future CMB experiments.
