description: We apply the joint lensing and dynamics code for the analysis of early-type galaxies, CAULDRON, to a rotating N-body stellar system with dark matter halo which significantly violates the two major assumptions of the method, i.e. axial symmetry supported by a two-integral distribution function. The goal is to study how CAULDRON performs in an extreme case, and to determine which galaxy properties can still be robustly recovered. Three data sets, corresponding to orthogonal lines of sight, are generated from the N-body system and analysed with the identical procedure followed in the study of real lens galaxies, adopting an axisymmetric power-law total density distribution. We find that several global properties of the N-body system are recovered with remarkable accuracy, despite the fact that the adopted power-law model is too simple to account for the lack of symmetry of the true density distribution. In particular, the logarithmic slope of the total density distribution is robustly recovered to within less than 10 per cent (with the exception of the ill-constrained very inner regions), the inferred angle-averaged radial profile of the total mass closely follows the true distribution, and the dark matter fraction of the system (inside the effective radius) is correctly determined within ~ 10 per cent of the total mass. Unless the line of sight direction is almost parallel to the total angular momentum vector of the system, reliably recovered quantities also include the angular momentum, the V/sigma ratio, and the anisotropy parameter delta. We conclude that the CAULDRON code can be safely and effectively applied to real early-type lens galaxies, providing reliable information also for systems that depart significantly from the method's assumptions.

An econometric analysis of the effects of labour market rationing on household labour supply
Creators: name: Ryan, David Leslie
Publisher: name: University of British Columbia
Year: 2010

description: Until recently, much of the labour supply literature has been predicated on the assumption that all individuals are free to choose the amount of labour that they supply at the prevailing wage rate. However, empirical studies have shown that many individuals are rationed to work more or fewer hours than they desire. In this thesis we formulate and estimate two models of household labour supply behaviour which take account of the fact that constraints in the labour, market prevent some (male) household heads from supplying their desired amount of labour. In the first model we consider the case where a male is constrained in the number of hours of labour he can supply in a working week. In the second model we decompose male leisure into leisure during working weeks and leisure during non-working weeks, and consider rations on both. To be consistent with the economic theory of consumer behaviour we derive these models by assuming that households, based on their preferences, perform an optimization procedure to determine their desired quantities of male leisure (provided it is not rationed), female leisure and goods consumption. Since we model household behaviour, by jointly estimating demand equations for rationed and non-rationed households we are able to examine the effects that rationing of the labour supply of the household head has on the labour supply of his spouse and on household goods consumption. We find that there is no general pattern to the way in which the marginal budget shares and labour supply elasticities differ among rationed and non-rationed households. Further, the relationship between the rationed and non-rationed marginal budget shares and elasticities differs according to the demographic characteristics of the household. We also find that our estimates differ from those obtained when rationed households are either ignored or omitted from the sample. In view of this result, and the fact that marginal budget shares and labour supply elasticities for rationed households cannot be calculated using the misspecified models, we conclude that it is important to use the entire sample of rationed and non-rationed households to estimate the model in which each type of rationing is modelled appropriately.

description: The first order optimality conditions of optimal control problems (OCPs) can be regarded as boundary value problems for Hamiltonian systems. Variational or symplectic discretisation methods are classically known for their excellent long term behaviour. As boundary value problems are posed on intervals of fixed, moderate length, it is not immediately clear whether methods can profit from structure preservation in this context. When parameters are present, solutions can undergo bifurcations, for instance, two solutions can merge and annihilate one another as parameters are varied. We will show that generic bifurcations of an OCP are preserved under discretisation when the OCP is either directly discretised to a discrete OCP (direct method) or translated into a Hamiltonian boundary value problem using first order necessary conditions of optimality which is then solved using a symplectic integrator (indirect method). Moreover, certain bifurcations break when a non-symplectic scheme is used. The general phenomenon is illustrated on the example of a cut locus of an ellipsoid.

Lithium depletion and the rotational history of exoplanet host stars

Subjects: subject: Astrophysics (astro-ph)

description: Israelian et al. (2004) reported that exoplanet host stars are lithium depleted compared to solar-type stars without detected massive planets, a result recently confirmed by Gonzalez (2008). We investigate whether enhanced lithium depletion in exoplanet host stars may result from their rotational history. We have developed rotational evolution models for slow and fast solar-type rotators from the pre-main sequence (PMS) to the age of the Sun and compare them to the distribution of rotational periods observed for solar-type stars between 1 Myr and 5 Gyr. We show that slow rotators develop a high degree of differential rotation between the radiative core and the convective envelope, while fast rotators evolve with little core-envelope decoupling. We suggest that strong differential rotation at the base of the convective envelope is responsible for enhanced lithium depletion in slow rotators. We conclude that lithium-depleted exoplanet host stars were slow rotators on the zero-age main sequence (ZAMS) and argue that slow rotation results from a long lasting star-disk interaction during the PMS. Altogether, this suggests that long-lived disks (> 5 Myr) may be a necessary condition for massive planet formation/migration.

description: Fractional Hamiltonian Monodromy is a generalization of the notion of Hamiltonian Monodromy, recently introduced by N. N. Nekhoroshev, D. A. Sadovskii and B. I. Zhilinskii for energy-momentum maps whose image has a particular type of non-isolated singularities. In this paper, we analyze the notion of Fractional Hamiltonian Monodromy in terms of the Gauss-Manin Monodromy of a Riemann surface constructed from the energy-momentum map and associated to a loop in complex space which bypasses the line of singularities. We also prove some propositions on Fractional Hamiltonian Monodromy for 1:-n and m:-n resonant systems.

Marbled white and brown in life (Fig 3 A), the colonies form sheets 2mm thick, investing rocks and sponges. Brown zooids are suspended between a thin layer of tunic filled with dense spicules and a compact basal layer. Dense brown cells (Fig. 4 A) are mixed with the spicules in the upper part of the colony. The abdomens are included into the basal tunic with dense spicules but sparse pigmented cells. The zooids are brown. The oral siphon is short (Fig. 3 B) with 6 short lobes. The wide atrial aperture, without languet, uncovers the most part of the branchial sac in relaxed zooids. Six stigmata are in the first row. Small oval lateral thoracic organs are placed above the fourth stigmata row. The retractor muscle extends from the top of the oesophageal neck. The digestive loop is well open, folded on itself, with well marked compartments. The single testis vesicle (Fig. 3 C) is spherical, protruding on the side and partly below the gut loop; it is completely encircled by 8–9 turns of the sperm duct. No ovary and no larvae were present. The spicules (Fig. 4 B) range in size to 40µm, the largest are stellate, while smaller ones have few very short rays, all with a fibrous structure.
 This species has characters in common with many Didemnum species, thus in the absence of larvae it cannot be identified at the species level. The presence of particularly large brown cells in the tunic and zooids is distinctive, they may be symbionts.

description: Measured response functions and low photon yield spectra of silicon photomultipliers (SiPM) were compared to multi-photoelectron pulse-height distributions generated by a Monte Carlo model. Characteristic parameters for SiPM were derived. The devices were irradiated with 14 MeV electrons at the Mainz microtron MAMI. It is shown that the first noticeable damage consists of an increase in the rate of dark pulses and the loss of uniformity in the pixel gains. Higher radiation doses reduced also the photon detection efficiency. The results are especially relevant for applications of SiPM in fibre detectors at high luminosity experiments.

description: Hundreds of millions of people lack access to electricity. Decentralised solar-battery systems are key for addressing this whilst avoiding carbon emissions and air pollution, but are hindered by relatively high costs and rural locations that inhibit timely preventative maintenance. Accurate diagnosis of battery health and prediction of end of life from operational data improves user experience and reduces costs. But lack of controlled validation tests and variable data quality mean existing lab-based techniques fail to work. We apply a scaleable probabilistic machine learning approach to diagnose health in 1027 solar-connected lead-acid batteries, each running for 400-760 days, totalling 620 million data rows. We demonstrate 73% accurate prediction of end of life, eight weeks in advance, rising to 82% at the point of failure. This work highlights the opportunity to estimate health from existing measurements using `big data' techniques, without additional equipment, extending lifetime and improving performance in real-world applications.

A single colony 4cm long and 0.5mm thick was of a cream colour in life (Fig. 6A), coating a bivalve shell. Its surface has a pattern in pavement, each system of zooids with a central common aperture. Spicules and round pigment cells are mixed at the tunic surface. The common cloacal cavity extends at the thoracic level and contains fecal pellets. The abdomens are included in the basal tunic filled with spicules. The zooids 8mm in length have 6 long, thin oral lobes (Fig. 5 B) contrasting with the contracted thorax. There is no languet above the wide atrial aperture. The lateral thoracic organs are leaf-shaped, very protruding (Fig. 5 B). The stigmata could not be counted. The waist is short with a retractor muscle as long as the thorax. The digestive loop (Fig. 5 C) is slightly twisted with a short stomach, a wide post-stomach and the intestine is divided in compartments. The single testis vesicle (Fig. 5 C) is circled with 5 to 6 turns of the sperm duct. An oocyte is present in many zooids of the colony but no larvae were detected. The spicules (Fig. 5 A) are regularly stellate up to 40µm in diameter, mixed with smaller ones. Large spicules of 60µm are rather common, with the same shape. The short rays have a hexagonal base.
 Didemnum sp.2 shares characters with Didemnum digestum Sluiter, 1909 and Didemnum uturoa Monniot & Monniot, 1987. These two species have particularly long oral lobes, but the shape of their spicules clearly differs in having one or several long rays among short ones. D. digestum has a single testis vesicle in the colony from Raja Ampat, while D. uturoa has 2 testis lobes. Didemnum sp. 2 may be a new species characterized by its spicules with few short rays of equal length, its long thin oral lobes, but without larvae and a single colony it does not seem wise to create a new species.

Population III.1 stars: formation, feedback and evolution of the IMF

subject: FOS: Physical sciences

description: I discuss current theoretical expectations of how primordial, Pop III.1 stars form. Lack of direct observational constraints makes this a challenging task. In particular predicting the mass of these stars requires solving a series of problems, which all affect, perhaps drastically, the final outcome. While there is general agreement on the initial conditions, H_2-cooled gas at the center of dark matter minihalos, the subsequent evolution is more uncertain. In particular, I describe the potential effects of dark matter annihilation heating, fragmentation within the minihalo, magnetic field amplification, and protostellar ionizing feedback. After these considerations, one expects that the first stars are massive >~100Msun, with dark matter annihilation heating having the potential to raise this scale by large factors. Higher accretion rates in later-forming minihalos may cause the Pop III.1 initial mass function to evolve to higher masses.

description: Diels-Alder cycloadditions are efficient routes for the synthesis of cyclic organic compounds. There has been a long-standing discussion whether these reactions proceed via stepwise or concerted mechanisms. Here, we adopt a new experimental approach to explore the mechanistic details of the model polar cycloaddition of 2,3-dibromo-1,3-butadiene with propene ions by probing its conformational specificities in the entrance channel under single-collision conditions in the gas phase. Combining a conformationally controlled molecular beam with trapped ions, we find that both conformers of the diene, gauche and s-trans, are reactive with capture-limited reaction rates. Aided by quantum-chemical and quantum-capture calculations, this finding is rationalised by a simultaneous competition of concerted and stepwise reaction pathways, revealing an interesting mechanistic borderline case.

Small pieces of thin encrusting colonies were red in life (Fig. 6 B) but are white in formalin. The colony surface is spotted by the oral apertures. The oral lobes are filled with spicules in the centre of a ring of tunic with less dense spicules. The zooids are small: 0.7mm for the best relaxed zooids. The common cloacal cavity is narrow and restricted to the thoracic level. The oral lobes are triangular on a short siphon. The atrial opening is narrow without a languet (Fig. 7 B). The lateral thoracic organs are small in the centre of each body side. The number of stigmata could not be determined in the 4 rows. The muscular appendage starts from the base of the thorax. The waist is short. The gut loop is flat with well marked segments (Fig. 7 C). The single testis lobe lies on the side of the rectum with 5–6 turns of the sperm duct. In some zooids, an oocyte as large as the testis is present. No larvae have been found in the colonies.
 The spicules (Fig. 7 A) are spheres of different sizes, from 20 to 40µm in diameter. Their very short rays have a hexagonal base, a blunt point and are made of incompletely fused elements. This spicule shape is not common in the genus Didemnum but alone, it cannot lead to a species identification in the absence of larvae in the colony and with no unique characters of the zooids.

description: We analyze the generation of helical magnetic fields during preheating in a model of low-scale electroweak (EW) hybrid inflation. We show how the inhomogeneities in the Higgs field, resulting from tachyonic preheating after inflation, seed the magnetic fields in a way analogous to that predicted by Vachaspati and Cornwall in the context of the EW symmetry breaking. At this stage, the helical nature of the generated magnetic fields is linked to the non-trivial winding of the Higgs-field. We analyze non-perturbatively the evolution of these helical seeds through the highly non-linear stages of symmetry breaking (SB) and beyond. Electroweak SB occurs via the nucleation and growth of Higgs bubbles which squeeze the magnetic fields into string-like structures. The W-boson charge density clusters in lumps around the magnetic strings. After symmetry breaking, a detailed analysis of the magnetic field Fourier spectrum shows two well differentiated components: a UV radiation tail at a temperature T ~ 0.23 m_higgs slowly growing with time, and an IR peak associated to the helical magnetic fields, which seems to follow inverse cascade. The system enters a regime in which we observe that both the amplitude (ρ_B/ρ_{EW} ~ 0.01) and the correlation length of the magnetic field grow linearly with time. During this stage of evolution we also observe a power-law growth in the helical susceptibility. These properties support the possibility that our scenario could provide the seeds eventually evolving into the microgauss fields observed today in galaxies and clusters of galaxies.

description: Triple-component fermions are pseudospin-1 quasiparticles hosted by certain three-band semimetals in the vicinity of their band-touching nodes [Phys. Rev. B {\bf 100}, 235201 (2019)]. The excitations comprise of a flat band and two dispersive bands. The energies of the dispersive bands are $E_{\pm}=\pm\sqrt{α^2_n k^{2n}_\perp+v^2_z k^2_z}$ with $k_\perp=\sqrt{k^2_x+k^2_y}$ and $n=1,2,3$. In this work, we obtain the exact expression of Berry curvature, approximate form of density of states and Fermi energy as a function of carrier density for any value of $n$. In particular, we study the Berry curvature induced electrical and thermal magnetotransport properties of quadratic $(n=2)$ triple-component fermions using semiclassical Boltzmann transport formalism. Since the energy spectrum is anisotropic, we consider two orientations of magnetic field (${\bf B}$): (i) ${\bf B}$ applied in the $x$-$y$ plane and (ii) ${\bf B}$ applied in the $x$-$z$ plane. For both the orientations, the longitudinal and planar magnetoelectric/magnetothermal conductivities show the usual quadratic-$B$ dependence and oscillatory behaviour with respect to the angle between the applied electric field/temperature gradient and magnetic field as observed in other topological semimetals. However, the out-of-plane magnetoconductivity has an oscillatory dependence on angle between the applied fields for the second orientation but is angle-independent for the first one. We observe large differences in the magnitudes of transport coefficients for the two orientations at a given Fermi energy. A noteworthy feature of quadratic triple-component fermions which is typically absent in conventional systems is that certain transport coefficients and their ratios are independent of Fermi energy within the low-energy model.

description: Using the linearity property of the Mullins-Herring equation when the velocity is zero with a Gaussian noise, we obtain an analytic form for the global mean-square surface width and height-height correlation function. This can be used to read the critical exponents in any dimension. In particular for d=1 we show that although the surface is super rough the system exhibits Family-Vicsek scaling behavior.

Magnetic resonance on atomic hydrogen confined by liquid helium walls
Creators: name: Morrow, Michael Robert
Publisher: name: University of British Columbia
Year: 2010

description: A gas of atomic hydrogen confined at and below 1K in a sealed cell has been studied by magnetic resonance at the zero-field hyperfine transition frequency of 1420 MHz. A review is presented of magnetic resonance theory for a two level system, with emphasis on determination of the absolute magnetization by two methods: calibration of the spectrometer sensitivity and by use of the radiation damping time constant. Measurements at 1K on a gas at low density, 10¹¹<n[sub=H]<5x10¹² cm⁻³, in the saturated ⁴He vapour density have yielded the rate for the reaction H+H+He￫H₂+He, the diffusion constant and pressure shift of the hyperfine transition for H interacting with the He gas, and the cross-section for spin exchange relaxation. At temperatures below 1K, measurements of the frequency shift and effective recombination rate for H adsorbed on the He film have yielded values of the binding energies for H on ³He and for H on ³He as well as the hyperfine transition frequency shift and surface recombination rate for H adsorbed on each of these surfaces. The binding energies are found to be 1.15(5) K for H on ³He and 0.42(5) K for H on ³He. Measurements have been carried out at temperatures as low as 162 mK for H on ³He and 65 mK for H on ³He. lineshape for H atoms undergoing occasional sticking events on the helium surface. This model has been applied to frequency shift and transverse relaxation data at low temperatures to yield sticking probabilities of 0.046(5) for H on ³He and 0.016(5) for H on ³He.

Shape and orientation of stellar velocity ellipsoids in spiral galaxies

Year: 2007

description: We present a numerical study of the properties of the stellar velocity distribution in stellar discs which have developed a saturated, two-armed spiral structure. We follow the growth of the spiral structure deeply into the non-linear regime by solving the Boltzmann moment equations up to second order. By adopting the thin-disc approximation, we restrict our study of the stellar velocity distribution to the plane of the stellar disc. We find that the outer (convex) edges of stellar spiral arms are characterized by peculiar properties of the stellar velocity ellipsoids, which make them distinct from most other galactic regions. In particular, the ratio σ_1:σ_2 of the smallest versus largest principal axes of the stellar velocity ellipsoid can become abnormally small (as compared to the rest of the disc) near the outer edges of spiral arms. Moreover, the epicycle approximation fails to reproduce the ratio of the tangential versus radial velocity dispersions in these regions. These peculiar properties of the stellar velocity distribution are caused by large-scale non-circular motions of stars, which in turn are triggered by the non-axisymmetric gravitational field of stellar spiral arms. The magnitude of the vertex deviation appears to correlate globally with the amplitude of the spiral stellar density perturbations. However, locally there is no simple correlation between the vertex deviation and the density perturbations. (Abstract abridged).

Reading the digital city in Africa
Creators: name: Pucciarelli, Marta
name: Cantoni, Lorenzo
Publisher: name: Zenodo
Year: 2021
Subjects: Digital city in Africa, Douala, Digital divide, ICT4D

description: Aims: This research studies the development of the digital city of Douala (Cameroun) and its relationships with the physical city, by analysing the online presence of socio-economic categories, their origin, online visible/invisible urban spaces, and their evolution over the time. Key findings and ideas: We need to combine synchronic/diachronic views to get a comprehensive representation of how a digital city is produced and how it is evolving. The synchronic view provides a static picture of the digital city and the emerging online representation mirrors a parallelism between digital and social inclusion/exclusion; the diachronic view depicts the movement, the changing picture of the digital city in the making and the social transition of Douala toward becoming an information/knowledge society.

description: In this work, we use observations of the Hubble parameter from the differential ages of passively evolving galaxies and the recent detection of the Baryon Acoustic Oscillations (BAO) at $z_1=0.35$ to constrain the Dvali-Gabadadze-Porrati (DGP) universe. For the case with a curvature term, we set a prior $h=0.73\pm0.03$ and the best-fit values suggest a spatially closed Universe. For a flat Universe, we set $h$ free and we get consistent results with other recent analyses.

description: We analyze the details of mass exchange in the vicinity of the Coulomb barrier for heavy-ion collisions involving neutron-rich nuclei using the time-dependent Hartree-Fock (TDHF) theory. We discuss the time-dependence of transfer and show that the potential barriers seen by individual single-particle states can be considerably different than the effective barrier for the two interacting nuclei having a single center-of-mass. For this reason we observe a substantial transfer probability even at energies below the effective barrier.

description: Um die Bedürfnisse des Kunden nach schnellem Internet und digitaler Technologie zu befriedigen, plant die Wohnungsgenossenschaft eG Magdeburg MWG Wohnungen mit FTTH-Installationen zu versorgen. Das Problem sind die erheblichen Kosten, welche bei der FTTH-Installation anfallen. Hier setzt diese Arbeit mit der Analyse von Optionen an, welche Kosteneinsparungen möglich sind. Um diese Analyse zu unterstützen wurden zur Informationsbeschaffung viele Recherchen betrieben und einige Experteninterviews durchgeführt. Die Analyse hat gezeigt, dass die geplante FTTH-Installation eigentlich für diesen Gebäudetyp P2 M10 schon sehr optimiert ist. Allerdings könnte man noch bei den Brandschutzmaterialien und Glasfaser-Gebäudeverteilern Kosten sparen.
