Mantidactylus betsileanus

description: Mantidactylus betsileanus clade
A rather species-rich clade of small to medium sized species (21.1–40.0 mm adult SVL), most of which are characterized by comparatively slender body shape with comparatively long limbs, relative to most other Brygoomantis species, and a more or less strongly expressed white tip on the snout. Contains: M. betsileanus, M. noralottae, M. tripunctatus (revalidated herein) and five new species (named based on holotypes depicted in Fig. 33). Note that several morphologically or bioacoustically similar species previously considered to be related to M. betsileanus (e.g. Glaw & Vences 2007) are here placed in a different clade (M. fergusoni clade, see below)

description: We report the identification of presolar silicates (~177 ppm), presolar oxides (~11 ppm), and one presolar SiO2 grain in the Allan Hills (ALHA) 77307 chondrite. Three grains having Si isotopic compositions similar to SiC X and Z grains were also identified, though the mineral phases are unconfirmed. Similar abundances of presolar silicates (~152 ppm) and oxides (~8 ppm) were also uncovered in the primitive CR chondrite Queen Elizabeth Range (QUE) 99177, along with 13 presolar SiC grains and one presolar silicon nitride. The O isotopic compositions of the presolar silicates and oxides indicate that most of the grains condensed in low-mass red giant and asymptotic giant branch stars. Interestingly, unlike presolar oxides, few presolar silicate grains have isotopic compositions pointing to low-metallicity, low-mass stars (Group 3). The 18O-rich (Group 4) silicates, along with the few Group 3 silicates that were identified, likely have origins in supernova outflows. This is supported by their O and Si isotopic compositions. Elemental compositions for 74 presolar silicate grains were determined by scanning Auger spectroscopy. Most of the grains have non-stoichiometric elemental compositions inconsistent with pyroxene or olivine, the phases commonly used to fit astronomical spectra, and have comparable Mg and Fe contents. Non-equilibrium condensation and/or secondary alteration could produce the high Fe contents. Transmission electron microscopic analysis of three silicate grains also reveals non-stoichiometric compositions, attributable to non-equilibrium or multistep condensation, and very fine scale elemental heterogeneity, possibly due to subsequent annealing. The mineralogies of presolar silicates identified in meteorites thus far seem to differ from those in interplanetary dust particles.

Estuarine particles simulations: the connection between Delaware Bay and offshore wind lease areas
Creators: name: Li, Yachen
Publisher: name: No Publisher Supplied
Year: 2023

description: The issue of microplastics is becoming increasingly severe; meanwhile, there is a surge in the construction of offshore wind farms. The base of wind turbines can act as artificial reefs, playing a positive role in facilitating the proliferation of a variety of marine organisms and the establishment of ecosystems. However, the potential impact of microplastics from estuaries on the ecosystems within wind farms is concerning. In this study, we use the particle tracking model ROMSPath to perform a simulation tracking the trajectories of 3650 particles over a year to reveal the connectivity from Delaware Bay to offshore wind lease areas located in the Mid-Atlantic Bight. The results suggest that 92% of the particles released from Delaware Bay did not remain in any wind lease areas after 180 days. A total of 26 wind lease areas were reached by the particles, with the area hosting the highest percentage capturing up to 41% of the particles. The particles were released from the Delaware River near Wilmington, DE and it took a minimum of 54 days for them to reach the wind lease area nearest to the bay mouth. The average residence time of the particles ranges from 0.14 to 6.5 days, indicating it would be reasonable to assume a particular impact from estuarine outflow on the wind lease area ecosystems. This study provides a reference for understanding estuarine particles' dispersion and migration patterns entering offshore wind development zones.

description: We introduce a patch to the commonly used public codes CAMB and CosmoMC that allows the user to implement a general modification of the equations describing the growth of cosmological perturbations, while preserving the covariant conservation of the energy-momentum. This patch replaces the previously publicly released code MGCAMB, while also extending it in several ways. The new version removes the limitation of late-time-only modifications to the perturbed Einstein equations, and includes several parametrization introduced in the literature. To demonstrate the use of the patch, we obtain joint constraints on the neutrino mass and parameters of a scalar-tensor gravity model from CMB, SNe and ISW data as measured from the correlation of CMB with large scale structure.

Temperature-driven spectral weight transfer in doped magnetic insulators
Creators: name: Möller, Mirko
Publisher: name: University of British Columbia
Year: 2017

description: In this thesis we study the effects of finite temperature (T ) on the single-electron spectral function of doped magnetic insulators. First, we derive the low-temperature correction to the self-energy of a charge carrier injected with parallel spin into a ferromagnetic background which is modeled with both Heisenberg and Ising Hamiltonians so that differences due to gapless versus gapped magnons can be understood. Beside the expected thermal broadening of the T = 0 quasiparticle peak which becomes a resonance inside a continuum, we find that spectral weight is transferred to regions lying outside this continuum, because the carrier and a thermal magnon can bind into a spin-polaron. This work is valid in dimensions d ≥ 2, because it does not include the role of magnetic domains which are important in 1d. We then consider the role of these magnetic domains in 1d systems, for models where spin-polaron formation is impossible. We present Monte Carlo simulations for the spectral function of three related models of a charge carrier that is injected into an Ising chain. Both ferromagnetic and antiferromagnetic coupling between the Ising spins are considered. The interaction between the carrier and the Ising spins is also of Ising type. In two of the models the charge carrier is hosted by a different band, while in the third model it is hosted by the same band as the Ising spins. We find that the carrier’s spectral function exhibits a distinctive fine structure due to its temporary entrapping inside small magnetic domains, and use these results to construct an accurate (quasi)analytic approximation for low and medium T . While at T = 0, for ferromagnetic order all three models have identical, low-energy quasiparticles, at finite T the low-energy behavior of the first two models remains equivalent, but that of the third model is controlled by rare events due to thermal fluctuations, which transfer spectral weight below the T = 0 quasiparticle peak, generating a pseudogaplike phenomenology. Taken together, our results show that the temperature evolution of the spectral weight of weakly doped magnetic insulators can be very complex.

Removable Matter-Power-Spectrum Covariance from Bias Fluctuations
Creators: name: Neyrinck, Mark C.
Publisher: name: arXiv
Year: 2011
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: We find a simple, accurate model for the covariance matrix of the real-space cosmological matter power spectrum on slightly nonlinear scales (k~0.1-0.8 h/Mpc at z=0), where off-diagonal matrix elements become substantial. The model includes a multiplicative, scale-independent modulation of the power spectrum. It has only one parameter, the variance (among realizations) of the variance of the nonlinear density field in cells, with little dependence on the cell size between 2-8 Mpc/h. Furthermore, we find that this extra covariance can be modeled out by instead measuring the power spectrum of (delta/sigma_cell), i.e. the ratio of the overdensity to its dispersion in cells a few Mpc in size. Dividing delta by sigma_cell essentially removes the non-Gaussian part of the covariance matrix, nearly diagonalizing it.

Year: 2010

description: The paper describes a concept of a secondary controlled traction drive integrated in a common Load Sensing system. When used in a single circuit system, a secondary controlled drive for tracked vehicles shows a big efficiency optimisation potential compared to other drives. The high losses at turns can be avoided if two secondary controlled units are connected to a single Load Sensing valve. The traction drive is still supplied in a traditional way using Load Sensing. For steering, the secondary controlled units are integrated in a control loop where the steering ratio is used as command value.

Year: 2010

description: Im Entwicklungsprozess von mobilen Arbeitsmaschinen spielt die Simulation eine immer wichtigere Rolle. Dabei müssen komplexe Systeme aus Mechanik, Hydraulik und Regelung abgebildet werden. Die heute verfügbaren Simulationsprogramme bieten nur mit Einschränkungen die Möglichkeit, diese Systeme mit einem Programm komplett abzubilden. Daneben ist es möglich, für jede Disziplin ein spezialisiertes Programm zu verwenden und durch eine so genannte Co-Simulation zu verbinden. Zahlreiche Programme bieten bereits derartige Schnittstellen an, aber insbesondere bei der Einbindung komplexer hydraulischer Systeme sind noch verschiedene Schwierigkeiten zu überwinden. 

Hier soll das Projekt GUSMA Grundlagen erarbeiten und die Anwendung einer Co-Simulation an einem typischen Beispiel einer geregelten Komforthydraulik aufzeigen. Der Prozess der Co-Simulation soll standardisiert und eine Plattform etabliert werden, auf der die gekoppelte Simulation anhand einer standardisierten Vorgehensweise durchgeführt werden kann. Um die gewachsene enge Lieferantenbeziehung, die für den Bereich der mobilen Arbeitsmaschinen typisch ist, auszubauen, soll die Möglichkeit geschaffen werden, Teilsimulationsmodelle des Lieferanten in das Gesamtmodell einzubauen. Dabei muss ein besonderes Augenmerk auf das Thema Know-how Schutz gelegt werden.

The Pioneers spacecrafts were decelerated, and their spin when not disturbed, was declining. On the other hand, fly-bys for gravity assists, appeared with extra speeds, relative to infinity. The Pioneers and fly-by anomalies are given now exact general relativistic full general solutions, in a rotating expanding Universe.We cite new evidence on the rotation of the Universe. Our solution seems to be the only one that solves the three anomalies.

The mechanism is sensitive to the neutrino emission model and to neutrino oscillations. We discuss the implications of an r-process that could alter interpretations of abundance data from metal-poor stars, and point out the need for further calculations that include effects of the supernova shock.

Six-dimensional Methods for Four-dimensional Conformal Field Theories

description: The calculation of both spinor and tensor Green's functions in four-dimensional conformally invariant field theories can be greatly simplified by six-dimensional methods. For this purpose, four-dimensional fields are constructed as projections of fields on the hypercone in six-dimensional projective space, satisfying certain transversality conditions. In this way some Green's functions in conformal field theories are shown to have structures more general than those commonly found by use of the inversion operator. These methods fit in well with the assumption of AdS/CFT duality. In particular, it is transparent that if fields on AdS$_5$ approach finite limits on the boundary of AdS$_5$, then in the conformal field theory on this boundary these limits transform with conformal dimensionality zero if they are tensors (of any rank), but with conformal dimension 1/2 if they are spinors or spinor-tensors.

Flow characteristics of single and double liquid jet impingement
Creators: name: Mohajer, Behzad
Publisher: name: University of British Columbia
Year: 2017

description: In the past few decades, the increasing demands for superior cooling systems in various industries have shifted the focus onto impinging liquid jets as an efficient, powerful cooling technique. Although much has been done on the thermal aspects of jet impingement, the available knowledge still lacks an in-depth understanding of the fluid dynamics involved in the phenomena that dictate the associated transport mechanisms. The present thesis has been planned to study the fluid dynamics of the interaction between a liquid, free-surface impinging jet with a solid surface, and also with a neighboring jet. The circular hydraulic jump as a key feature of a free-surface jet impingement was analyzed. The focus was given to the influence of the target plate on the behavior of the hydraulic jump. Two conditions for the target plate were examined: large plates with capillary limit at the edge, and also small target plates. It was experimentally and theoretically discussed that the circular jumps with these two conditions exhibit different behaviors from those presented in the literature. Furthermore, a systematic Froude number analysis on circular hydraulic jumps was carried out and the significant differences between circular jumps and the open-channel jumps were Highlighted. It was shown that due to the significant influence of the surface tension in circular jumps, the critical Froude number differs from that observed in the classical jumps and could be larger than unity. Moreover, the interaction between the flow fields formed by two jets impinging on a solid surface was investigated in detail. Understanding of this interaction is of significant importance due to the promising potentials of multiple jets for high heat flux applications. Two different configurations were studied: two vertical jets, and two inclined jets. The fluid dynamics involved in the collision between two thin liquid films formed on the surface was theoretically analyzed. A systematic experimental study was also carried out to examine the effects of different parameters on the flow field interaction. The experimental results were then compared to the theoretical predictions to verify the presented models. Good agreements were observed between the presented theory and the experimental data.

description: Alkylation of benzene with 1-decene for production of linear alkylbenzene in the presence of nanotitania (n-TiO2)-supported Dawson heteropolyacids was studied. Various operating parameters including benzene to 1-decene molar ratio, catalyst weight percent (wt%), catalyst loading (wt%), calcination temperature, reaction time, and temperature influenced the reaction yield. Fractional factorial design was employed to screen these parameters, and significant parameters modeled by a central composite design. Finally, the best conditions were defined by using nonlinear Nelder-Mead optimization to reach maximum reaction yield.

We study the effect of initial state fluctuations and finite viscosities on the flow coefficients v_2 and v_3 as functions of transverse momentum and pseudo-rapidity. Fluctuations are essential to reproduce the measured centrality dependence of elliptic flow. We argue that simultaneous measurements of v_2 and v_3 can determine eta/s more precisely.

description: We consider a (small) quantum mechanical system which is operated by an external agent, who changes the Hamiltonian of the system according to a fixed scenario. In particular we assume that the agent (who may be called a demon) performs measurement followed by feedback, i.e., it makes a measurement of the system and changes the protocol according to the outcome. We extend to this setting the generalized Jarzynski relations, recently derived by Sagawa and Ueda for classical systems with feedback. One of the two relations by Sagawa and Ueda is derived here in error-free quantum processes, while the other is derived only when the measurement process involves classical errors. The first relation leads to a second law which takes into account the efficiency of the feedback.

description: We introduce a novel method to measure the masses of galaxy clusters at high redshift selected from optical and IR Spitzer data via the red-sequence technique. Lyman-break galaxies are used as a well understood, high-redshift background sample allowing mass measurements of lenses at unprecedented high redshifts using weak lensing magnification. By stacking a significant number of clusters at different redshifts with average masses of ~1-3x10^14M_sun, as estimated from their richness, we can calibrate the normalisation of the mass-richness relation. With the current data set (area: 6 deg^2) we detect a magnification signal at the >3-sigma level. There is good agreement between the masses estimated from the richness of the clusters and the average masses estimated from magnification, albeit with large uncertainties. We perform tests that suggest the absence of strong systematic effects and support the robustness of the measurement. This method - when applied to larger data sets in the future - will yield an accurate calibration of the mass-observable relations at z>~1 which will represent an invaluable input for cosmological studies using the galaxy cluster mass function and astrophysical studies of cluster formation. Furthermore this method will probably be the least expensive way to measure masses of large numbers of z>1 clusters detected in future IR-imaging surveys.

description: The ATLAS detector at the Large Hadron Collider has collected several hundred million cosmic ray events during 2008 and 2009. These data were used to commission the Muon Spectrometer and to study the performance of the trigger and tracking chambers, their alignment, the detector control system, the data acquisition and the analysis programs. We present the performance in the relevant parameters that determine the quality of the muon measurement. We discuss the single element efficiency, resolution and noise rates, the calibration method of the detector response and of the alignment system, the track reconstruction efficiency and the momentum measurement. The results show that the detector is close to the design performance and that the Muon Spectrometer is ready to detect muons produced in high energy proton-proton collisions.

description: The Mount Wilson Ca HK survey revealed magnetic activity variations in a large sample of solar-type stars with timescales ranging from 2.5 to 25 years. This broad range of cycle periods is thought to reflect differences in the rotational properties and the depths of the surface convection zones for stars with various masses and ages. In 2007 we initiated a long-term monitoring campaign of Ca II H and K emission for a sample of 57 southern solar-type stars to measure their magnetic activity cycles and their rotational properties when possible. We report the discovery of a 1.6-year magnetic activity cycle in the exoplanet host star iota Horologii, and we obtain an estimate of the rotation period that is consistent with Hyades membership. This is the shortest activity cycle so far measured for a solar-type star, and may be related to the short-timescale magnetic variations recently identified in the Sun and HD49933 from helio- and asteroseismic measurements. Future asteroseismic observations can be compared to those obtained near the magnetic minimum in 2006 to search for cycle-induced shifts in the oscillation frequencies. If such short activity cycles are common in F stars, then NASA's Kepler mission should observe their effects in many of its long-term asteroseismic targets.

description: Macroeconomic forecasts are used extensively in industry and government even though the historical accuracy and reliability is disputed. This thesis develops and studies a prediction market designed to forecast macro-economic indicators in Germany. The market forecasts performed well in comparison to the 'Bloomberg'-survey forecasts. Distinguishing between trading behavior and performance the thesis provides insights into the interplay between interface, information and decision-making.
Constraints on coronal turbulence models from source sizes of noise storms at 327 MHz

description: We seek to reconcile observations of small source sizes in the solar corona at 327 MHz with predictions of scattering models that incorporate refractive index effects, inner scale effects and a spherically diverging wavefront. We use an empirical prescription for the turbulence amplitude $C_{N}^{2}(R)$ based on VLBI observations by Spangler and coworkers of compact radio sources against the solar wind for heliocentric distances $R \approx$ 10--50 $R_{\odot}$. We use the Coles & Harmon model for the inner scale $l_{i}(R)$, that is presumed to arise from cyclotron damping. In view of the prevalent uncertainty in the power law index that characterizes solar wind turbulence at various heliocentric distances, we retain this index as a free parameter. We find that the inclusion of spherical divergence effects suppresses the predicted source size substantially. We also find that inner scale effects significantly reduce the predicted source size. An important general finding for solar sources is that the calculations substantially underpredict the observed source size. Three possible, non-exclusive, interpretations of this general result are proposed. First and simplest, future observations with better angular resolution will detect much smaller sources. Consistent with this, previous observations of small sources in the corona at metric wavelengths are limited by the instrument resolution. Second, the spatially-varying level of turbulence $C_{N}^{2}(R)$ is much larger in the inner corona than predicted by straightforward extrapolation Sunwards of the empirical prescription, which was based on observations between 10--50 $R_{\odot}$. Either the functional form or the constant of proportionality could be different. Third, perhaps the inner scale is smaller than the model, leading to increased scattering.

The contribution of X-ray binaries to the evolution of late-type galaxies: Evolutionary population synthesis simulations

description: X-ray studies of normal late-type galaxies have shown that non-nuclear X-ray emission is typically dominated by X-ray binaries, and provides a useful measure of star formation activity. We have modeled the X-ray evolution of late-type galaxies over the $\sim$ 14 Gyr of cosmic history, with an evolutionary population synthesis code developed by Hurley et al. Our calculations reveal a decrease of the X-ray luminosity-to-mass ratio $L_{\rm X}/M$ with time, in agreement with observations (Fig.~7$a$). We show that this decrease is a natural consequence of stellar and binary evolution and mass accumulating process in galaxies. The X-ray-to-optical luminosity ratio $L_{\rm X}/L_{\rm B}$ is found to be fairly constant (around $\sim 10^{30}$ erg\,s$^{-1}$$L_{\rm B,\odot}^{-1}$, Fig.~7$b$), and insensitive to the star formation history in the galaxies. The nearly constant value of $L_{\rm X}/L_{\rm B}$ is in conflict with the observed increase in $L_{\rm X}/L_{\rm B}$ from $z=0$ to 1.4. The discrepancy may be caused by intense obscured star formation activity that leads to nonlinear relationship between X-ray and B-band emission.

Probing cosmic star formation up to z = 9.4 with GRBs

description: We propose a novel approach, based on Principal Components Analysis, to the use of Gamma-Ray Bursts (GRBs) as probes of cosmic star formation history (SFH) up to very high redshifts. The main advantage of such approach is to avoid the necessity of assuming an \textit{ad hoc} parameterization of the SFH. We first validate the method by reconstructing a known SFH from Monte Carlo-generated mock data. We then apply the method to the most recent \textit{Swift} data of GRBs with known redshift and compare it against the SFH obtained by independent methods. The main conclusion is that the level of star formation activity at $z \approx 9.4$ could have been already as high as the present-day one ($\approx 0.01 M_\odot$ yr$^{-1}$ Mpc$^{-3}$). This is a factor 3-5 times higher than deduced from high-$z$ galaxy searches through drop-out techniques. If true, this might alleviate the long-standing problem of a photon-starving reionization; it might also indicate that galaxies accounting for most of the star formation activity at high redshift go undetected by even the most deep searches.

The Douglas–Rachford operator in the possibly inconsistent case : static properties and dynamic behaviour
Creators: name: Moursi, Walaa M.
Publisher: name: University of British Columbia
Year: 2017

description: The problem of finding a minimizer of the sum of two convex functions – or, more generally, that of finding a zero of the sum of two maximally monotone operators – is of central importance in variational analysis and optimization. Perhaps the most popular method of solving this problem is the Douglas–Rachford splitting method. Surprisingly, little is known about the behaviour of the algorithm in the general inconsistent case, i.e., when the sum problem has no zeros. This thesis provides a comprehensive study of the Douglas–Rachford operator and the corresponding algorithm. First, a novel framework of the normal problem that copes with the possibly inconsistent situation is introduced and studied. We present a systematic study of the range of the operator and displacement map, which provides precise information on the minimal displacement vector needed to define the normal problem. A new Fejér monotonicity principle as well as new identities for the Douglas–Rachford operator are developed. A systematic and detailed study of affine nonexpansive operators and their asymptotic behaviour is presented. In the light of the new analysis, we significantly advance the understanding of the inconsistent case by providing a complete proof of the full weak convergence of the shadow sequence to a best approximation solution in the convex feasibility setting. In fact, a more general sufficient condition for weak convergence in the general case is presented. Under some extra assumptions, we were able to prove strong and linear convergence. Our results are illustrated through numerous examples. We conclude with a list of open problems which serve as promising directions of future research.

description: Correlation functions of the two-dimensional Ising model on the periodic lattice can be expressed in terms of form factors - matrix elements of the spin operator in the basis of common eigenstates of the transfer matrix and translation operator. Free-fermion structure of the model implies that any multiparticle form factor is given by the pfaffian of a matrix constructed from the two-particle ones. Crossed two-particle form factors can be obtained by inverting a block of the matrix of linear transformation induced on fermions by the spin conjugation. We show that the corresponding matrix is of elliptic Cauchy type and use this observation to solve the inversion problem explicitly. Non-crossed two-particle form factors are then obtained using theta functional interpolation formulas. This gives a new simple proof of the factorized formulas for periodic Ising form factors, conjectured by A. Bugrij and one of the authors.
