description: We provide an infinity of spacetimes which contain part of both the Schwarzschild vacuum and de Sitter space. The transition, which occurs below the Schwarzschild event horizon, involves only boundary surfaces (no surface layers). An explicit example is given in which the weak and strong energy conditions are satisfied everywhere (except in the de Sitter section) and the dominant energy condition is violated only in the vicinity of the boundary to the Schwarzschild section. The singularity is avoided by way of a change in topology in accord with a theorem due to Borde..

When Does Natural Resource Abundance Lead to a Resource Curse?

description: This paper looks at the relationship between natural resource endowment, particularly the type associated with minerals and plantations, and economic development. It may not be natural resource endowment per se but its type that matters, when it comes to growth and development. Certain types of natural resources such as oil and minerals have a tendency to lead to production and revenue patterns that are concentrated, while revenue flows from other types of resources such as agriculture are more diffused throughout the economy. The former category is dubbed a point-source economies, while the latter type is referred to as diffuse. Most countries in the first group have been prone to growth failure in recent times, with notable exceptions such as Botswana and Indonesia. The paper reviews two sets of models, the first set outlining the onset of the resource curse, and the second category sketching conditions where resource booms actually aid growth, or policies to avoid the resource curse. The vast majority of these models stress intersectoral linkages. Political economy considerations associated with resource rents are also reviewed. The focus is on institutions that determine the policy superstructure. The importance of institutions is highlighted, followed by a sketch of institutional malfunctioning and an overview of the empirical models of institutional determination. An explicit model of growth collapse with micro-foundations in rent-seeking behaviour and contests is also presented. The empirical analysis put forward is one of the few econometric investigations into the resource curse that includes analysis over time, as it is a panel data estimation. Due to this time series property our proxy for institutional quality is the degree of democracy. Our findings suggest that a point-source type natural resource endowment does retard democratic and institutional development, which in turn hampers economic growth. Institutions and institutional functioning are the crucial link between resource endowments, geography and policies, on the one hand and economic outcomes on the other hand.
Functional characterization of a small nonstructural protein of the parvovirus B19
Creators: name: Fan, Mannie Man Yee
Publisher: name: University of British Columbia
Year: 2009

description: The pathogenic human parvovirus B19 produces a class of small, 11kDa proteins whose function is as yet undetermined. In the absence of a continuous permissive cell line in which B19 can be readily propagated, in vitro studies have been used to assess the functional role of the 11kDa proteins. In previous studies, the 11kDa proteins have not been shown to be targets of phosphorylation or binding partners for other viral proteins, nor have they demonstrated Zn++-binding or transactivation activities. However, there is preliminary evidence that the 11kDa proteins are capable of interacting with the cellular growth factor receptor-binding protein 2 (Grb2) in vitro, and this thesis aims to investigate this interaction in greater detail. In studies reported in this thesis, far western experiments confirm in vitro interactions between Grb2 and the 11kDa proteins. Moreover, a fusion construct of the 11kDa protein with glutathione S-transferase (GST) is able to specifically pull down endogenous Grb2 from HEK 293 cell lysates, providing further support for our hypothesis that the two proteins interact. Grb2 is an important adaptor molecule in the MAPK signal transduction pathway leading to defined cellular responses. The protein is composed of a series of modular domains each specialized for a different function, including two SH3 domains that are capable of binding proline-rich sequences. Such sequences correspond to consensus "ligand" motifs found in binding partners for Grb2 such as son of sevenless (Sos), a guanine nucleotide exchange factor for the Ras small GTP-binding protein that is implicated in MAPK activation. Sos-like proline-rich regions are also present in the 11kDa proteins. Further studies have focused on the requirement for these regions in the Grb2/11kDa interaction. Far western studies employing 11kDa proteins mutated at proline residues suggest reduced interactions with Grb2. Furthermore, GST-11 mutant constructs do not precipitate Grb2 from mammalian cell lysates as readily as does the wild-type. These results indicate possible involvement of the proline-rich region in mediating interactions of the 11kDa proteins with Grb2, in an SH3- dependent manner. The findings from this thesis strongly support an interaction of the 11kDa proteins with the host protein Grb2 to influence host cell environment during the viral replicative cycle.

description: Over the last three decades, the demand for fish in the Amazon basin has greatly increased due to population growth in the main cities of the region. While technological improvements in commercial fishing methods have made it possible to meet this growing demand, they have led to concerns about the possible extinction of certain fish species and to conflicts over the resource between commercial fishermen and rural communities. This study reviews the current state of inland fisheries in the Amazon in order to analyse policy options for fisheries management, and identifies key gaps in information on the economic, social and biological aspects of fisheries which constrain policymakers.
On The Origin of the Local Group's Peculiar Velocity

Year: 2005
Subjects: subject: Astrophysics (astro-ph)

description: We aim to settle the debate regarding the fraction of the Local Group's peculiar velocity that is induced by structures beyond the Great Attractor by calculating the dipole anisotropy of the largest, all-sky, truly X-ray selected cluster sample compiled to date. The sample is the combination of the REFLEX catalog in the southern hemisphere, the eBCS sample in the north, and the CIZA survey in the Galactic plane. The composite REFLEX+eBCS+CIZA sample overcomes many of the problems inherent to previous galaxy and cluster catalogs which limited their effectiveness in determining the origin of the Local Group's motion. From the dipole anisotropy present in the cluster distribution we determine that 44% of the Local Group's peculiar velocity is due to infall into the GA region, while 56% is in the form of a large-scale flow induced by more distant overdensities between 130 and 180 h^-1 Mpc away. In agreement with previous analyses, we find that the Shapley supercluster is the single overdensity most responsible for the increase in the dipole amplitude beyond 130 h^-1 Mpc, generating 30.4% of the large-scale contribution. We find that numerous groupings and loose associations of clusters at roughly the same distance as the Shapley region induce a significant acceleration on the Local Group. These include the well known Horologium-Reticulum concentration, as well as newly noted associations centered on Abell 3667 and Abell 3391 and a string of CIZA clusters near C1410 which may trace an extension of the Shapley complex into the Zone of Avoidance. We also note that the large-scale anisotropy measured in the cluster distribution near 150 h^-1 Mpc may be due to an observed underdensity of clusters in the northern hemisphere near this distance.

description: We perform a large scale analysis of a list of fintech terms in (i) news and blogs in English language and (ii) professional descriptions of companies operating in many countries. The occurrence and co-occurrence of fintech terms and locutions shows a progressive evolution of the list of fintech terms in a compact and coherent set of terms used worldwide to describe fintech business activities. By using methods of complex networks that are specifically designed to deal with heterogeneous systems, our analysis of a large set of professional descriptions of companies shows that companies having fintech terms in their description present over-expressions of specific attributes of country, municipality, and economic sector. By using the approach of statistically validated networks, we detect geographical and economic over-expressions of a set of companies related to the multi-industry, geographically and economically distributed fintech movement.

description: We treat two possible phenomenological effects of quantum fluctuations of spacetime geometry: spectral line broadening and angular blurring of the image of a distance source. A geometrical construction will be used to express both effects in terms of the Riemann tensor correlation function. We apply the resulting expressions to study some explicit examples in which the fluctuations arise from a bath of gravitons in either a squeezed state or a thermal state. In the case of a squeezed state, one has two limits of interest: a coherent state which exhibits classical time variation but no fluctuations, and a squeezed vacuum state, in which the fluctuations are maximized.

description: In the next decades, the astrobiological community will debate whether the first observations of oxygen in an exoplanet$'$s atmosphere signifies life, so it is critical to establish procedures now for collection and interpretation of such data. We present a step-by-step observational strategy for using oxygen as a robust biosignature, to prioritize exoplanet targets and design future observations. It is premised on avoiding planets lacking subaerial weathering of continents, which would imply geochemical cycles drastically different from Earth$'$s, precluding use of oxygen as a biosignature. The strategy starts with the most readily obtained data: semi-major axis and stellar luminosity to ensure residence in the habitable zone; stellar XUV flux, to ensure an exoplanet can retain a secondary (outgassed) atmosphere. Next, high-precision mass and radius information should be combined with high-precision stellar abundance data, to constrain the exoplanet$'$s water content; those incompatible with less than 0.1 wt % H$_{2}$O can be deprioritized. Then, reflectance photometry or low-resolution transmission spectroscopy should confirm an optically thin atmosphere. Subsequent long-duration, high-resolution transmission spectroscopy should search for oxygen and ensure that water vapor and CO$_{2}$ are present only at low (10$^{2}$-10$^{4}$ ppm levels). Assuming oxygen is found, attribution to life requires the difficult acquisition of a detailed, multispectral light curve of the exoplanet to ensure both surface land and water. Exoplanets failing some of these steps might be habitable, even have observable biogenic oxygen, but should be deprioritized because oxygen could not be attributed unambiguously to life. We show how this is the case for the Solar System, the 55 Cnc System, and the TRAPPIST-1 System, in which only the Earth and TRAPPIST-1e successfully pass through our procedure.

description: The set of homology cobordisms from a surface to itself with markings of their boundaries has a natural monoid structure. To investigate the structure of this monoid, we define and study its Magnus representation and Reidemeister torsion invariants by generalizing Kirk-Livingston-Wang's argument over the Gassner representation of string links. Moreover, by applying Cochran and Harvey's framework of higher-order (non-commutative) Alexander invariants to them, we extract several pieces of information about the monoid and related objects.

description: Porous graphene (PG) is a graphene derivative endowed of nanoporous architectures. This material possesses a particular structure with interconnected networks of high pore volume, producing membranes with a large surface area. Experiments revealed that PG combines remarkable properties such as high mechanical strength and good thermal stability. In this work, we have carried out fully-atomistic reactive (ReaxFF) molecular dynamics simulations to perform a comprehensive study on the elastic properties, fracture mechanism, and thermal stability of 2D porous n-Benzo-CMPs (CMP and n refer, respectively, to pi-conjugated microporous polymers and the pore diameter) membranes with distinct nanoporous architectures. For comparison purposes, the results were also contrasted with the ones for graphene sheets of similar dimensions. We adopted three different nanoporous diameters: small (3.45 A), medium (8.07 A), and large (11.93 A). Results showed that PG is thermally stable up to 4660K, about 1000K smaller than the graphene melting point (5643K). During the PG heating, linear atomic chains are formed combining carbon and hydrogen atoms. The fracture strains range between 15%-34% by applying a uniaxial loading in both plane directions for temperatures up to 1200K. The fracture strain increases proportionally with the nanoporous size. Remarkably, the critical tensile strength for the PG complete fracture is temperature independent. Instead, it depends only on the nanoporous diameter. All the PG membranes go abruptly from elastic to completely fractured regimes after a critical strain threshold.

description: We develop a general scheme of deriving boundary conditions for spin-charge coupled transport in disordered systems with spin-orbit interactions. To illustrate the application of the method, we explicitly derive boundary conditions for spin diffusion in the Rashba model. Due to the surface spin precession, the boundary conditions are non-trivial and contain terms, which couple different components of the spin density. We argue that boundary conditions and the corresponding electric-field-induced spin accumulation generally depend on the nature of the boundary and therefore the spin Hall effect in a spin-orbit coupled system can be viewed as a non-universal edge phenomenon.

He joined up as a volunteer, belonging to the Ulster Volunteer Force, and may have done so in response to an appeal. He was born in 1891 in Belfast, so was 23 at the time. In June 1917, he lost an eye during the Battle of Messines and was therefore "honourably discharged", or invalided out, to Clopton House War Hospital in Stratford-upon-Avon. Between joining up and his discharge he had been promoted to a sergeant.
Economic Inequality and the Urban Environment: The Case of Water and Sanitation

description: This paper looks at the relationship between economic inequality and urban environmental quality in developing countries, with specific reference to the provision of water and sanitation services. The paper explores the consequences of 'dual' systems, in which a proportion of a city's residents are served by subsidised 'town' water and sanitation facilities, whilst another section of the city has been forced to develop a variety of 'on-site' strategies through their own efforts. A number of conclusions are reached: firstly, it is argued that poorer households are generally more adversely affected by low levels of provision and that standard project evaluation techniques perpetuate this bias; secondly, the cost structure of service provision implies that equal access to a standardised system is more efficient than the differentiated levels of access and treatment which prevail; and, thirdly, it is argued that access to water and sanitation and the means by which such systems are financed can be one of the most significant and effective means of distributing resources in the urban context.

Anisotropic deformations in a class of projectively-invariant metric-affine theories of gravity

description: Among the general class of metric-affine theories of gravity, there is a special class conformed by those endowed with a projective symmetry. Perhaps the simplest manner to realise this symmetry is by constructing the action in terms of the symmetric part of the Ricci tensor. In these theories, the connection can be solved algebraically in terms of a metric that relates to the spacetime metric by means of the so-called deformation matrix that is given in terms of the matter fields. In most phenomenological applications, this deformation matrix is assumed to inherit the symmetries of the matter sector so that in the presence of an isotropic energy-momentum tensor, it respects isotropy. In this work we discuss this condition and, in particular, we show how the deformation matrix can be anisotropic even in the presence of isotropic sources due to the non-linear nature of the equations. Remarkably, we find that Eddington-inspired-Born-Infeld theories do not admit anisotropic deformations, but more general theories do. However, we find that the anisotropic branches of solutions are generally prone to a pathological physical behaviour.

description: The fact that most extrasolar planets found to date are orbiting metal-rich stars lends credence to the core accretion mechanism of gas giant planet formation over its competitor, the disc instability mechanism. However, the core accretion mechanism is not refined to the point of explaining orbital parameters such as their unexpected semi-major axes and eccentricities. We propose a model, which correlates the metallicity of the host star with the original semi-major axis of its most massive planet, prior to migration, considering that the core accretion scenario governs giant gas planet formation. The model predicts that the optimum regions for planetary formation shift inward as stellar metallicity decreases, providing an explanation for the observed absence of long period planets in metal-poor stars. We compare our predictions with the available data on extrasolar planets for stars with masses similar to the mass of the Sun. A fitting procedure produces an estimate of what we define as the Zero Age Planetary Orbit (ZAPO) curve as a function of the metallicity of the star. The model also hints that the lack of planets circling metal-poor stars may be partly caused by an enhanced destruction probability during the migration process, since the planets lie initially closer to the central stars.
description: Nature of the replacement: According to recent simulations, the temperature profile, T, is more adequately reproduced by beta = 1 rather than beta = 2. We have introduced a distance scale factor that solves the very fast drop of T for low metallicity and introduces naturally the inferior distance limit of our ZAPO. Under this modification all the fitting process was altered

description: China's record in reducing rural poverty has been nothing short of spectacular and should be a source of lessons for other countries. Rural poverty reduction is generally sought in the role of agriculture in contributing to farm incomes. However, non-farm employment in rural areas can also be a major contributor. Using detailed household survey data from Hubei province, we simulate the counterfactual of what rural households' incomes, poverty, and inequality would be in the absence of access to non-farm sources of income. Results show that, without non-farm employment, rural poverty would be much higher and deeper, and that income inequality would be higher as well. We find that education, proximity to town, neighborhood effects, and village effects are crucial in helping particular households gain access to these opportunities. We also find that those who stay as pure farmers have non-observable characteristics that make them much more productive in agriculture, implying positive selection on these characteristics. Moreover, participation in non-farm activities has a positive spillover effect on household farm production.

The spectrum of the axial excited states strongly depends on the coupling among the various discrete radial modes in a given symmetry. By including mode-coupling within a given symmetry, the complete excitation spectrum of axial quasiparticles with various discrete radial nodes are presented. A single parameter which determines the strength of the mode coupling is identified. The excitation spectrum in the zero angular momentum sector can be observed by using the Bragg scattering experiments.

Geometric Drive of the Universe's Expansion

description: What if physics is just the way we perceive geometry? That is, what if geometry and physics will one day become one and the same discipline? I believe that will mean we will at last really understand physics, without postulates other than those defining the particular space where the physics play is performed. In this paper I use 5-dimensional spacetime as a point of departure and make a very peculiar assignment between coordinates and physical distances and time. I assume there is an hyperspherical symmetry which is made apparent by assigning the hypersphere radius to proper time and distances on the hypersphere to usual 3-dimensional distances. Time, or Compton time to distinguish from cosmic time is the 0th coordinate and I am able to project everything into 4-dimensions by imposing a null displacement condition. Surprisingly nothing else is needed to explain Hubble's expansion law without any appeal to dark matter; an empty Universe will expand naturally at a flat rate in this way. I then discuss the perturbative effects of a small mass density in the expansion rate in a qualitative way; quantitative results call for the solution of equations that sometimes have not even been clearly formulated and so are deferred to later work. A brief outlook of the consequences an hyperspherical symmetry has for galaxy dynamics allows the derivation of constant rotation velocity curves, again without appealing to dark matter. An appendix explains how electromagnetism is made consistent with this geometric approach and justifies the fact that photons must travel on hypersphere circles, to be normal to proper time.

description: A household model with differential asset endowments and idiosyncratic transactions costs in accessing labor markets is developed to (1) explain membership of farm households to alternative labor regimes (sellers, employers, or self-sufficient in labor), (2) test for recursivity between production and consumption decisions selectively by labor regime, and (3) identify the determinants of differential labor productivity across labor regimes. The model is applied to a 1994 household survey of the Mexican land reform sector. (Forthcoming in the Journal of Industrial Relations)

description: Binary black hole (BBH) mergers are the primary sources of gravitational wave (GW) events detected by LIGO/Virgo. Binary black holes embedded in the accretion discs of active galactic nuclei (AGN) are possible candidates for such GW events. We develop an idealised analytic model for the orbital evolution of BBHs in AGN accretion discs by combining the evolution equations of disc-binary interaction and GW inspiral. We investigate the coupled `disc+GW'-driven evolution of BBHs transitioning from the disc-driven regime at large orbital separations into the GW-driven regime at small separations. In this evolution channel, BBH mergers are accelerated by a combination of orbital decay and orbital eccentricity growth in the disc-dominated regime. We provide a quantification of the resulting merger timescale $τ_\text{merger}$, and analyse its dependence on both the accretion disc and binary orbital parameters. By computing the evolution of the orbital eccentricity as a function of the GW frequency, we predict that most binaries in AGN discs should have significant residual eccentricities ($e \sim 0.01-0.1$), potentially detectable by LISA. We further discuss the potentials and caveats of this particular BBH-in-AGN channel in the framework of binary evolutionary paths.

description: Using the mixed space representation, we extend our earlier analysis to the case of Dirac and gauge fields and show that in the absence of a chemical potential, the finite temperature Feynman diagrams can be related to the corresponding zero temperature graphs through a thermal operator. At non-zero chemical potential we show explicitly in the case of the fermion self-energy that such a factorization is violated because of the presence of a singular contact term. Such a temperature dependent term which arises only at finite density and has a quadratic mass singularity cannot be related, through a regular thermal operator, to the fermion self-energy at zero temperature which is infrared finite. Furthermore, we show that the thermal radiative corrections at finite density have a screening effect for the chemical potential leading to a finite renormalization of the potential.

description: This paper investigates how child labor and schooling are responsive to opportunities to work, in particular to opportunities provided by children's own parents. The paper demonstrates that after controlling for household, parental, regional, and child characteristics, children whose parents are self-employed or employers are more likely to work than children of employees, irrespective of the sector of parent activity. Furthermore, the paper also confirms a recent finding that children from areas with high average adult employment rates are more likely to work than children from areas with low average adult employment rates. Finally, since twice as many children of the self-employed and employers both work and go to school as those of employees, the paper suggests that child labor does not necessarily represent a trade off with schooling as it depends on the occupation of the parents.

description: A semiparametric estimator for evaluating the parameters of data generated under a sample selection process is developed. This estimator is based on the generalized maximum entropy estimator and performs well for small and ill-posed samples. Theoretical and sampling comparisons with parametric and semiparametric estimators are given. This method and standard ones are applied to three small-sample empirical applications of the wage-participation model for female teenage heads of households, immigrants, and Native Americans.

description: Sergeant Samuel Moulder was the grandfather of Richard Brown. He joined the army in 1897, aged 18, in the Second Battalion of Oxfordshire and Buckinghamshire Light Infantry. Moulder went straight to war in September 1914. He had been sending cards home, but they suddenly stopped arriving. His sister-in-law wrote to the war office and received a letter in December 1914 saying he wasn't on any casualty lists. Moulder's pay stopped, which meant his family had to leave their home in Eynsham to live in the Oxford slums. In January 1915 they received confirmation of his death; he had been in a battle at Langemarck on October 22nd 1914. They never found his body, but a friend said he had a bullet through his head. His name is listed on the Menin Gate in Ypres.
Gasoline Price Differences: Taxes, Pollution Regulations, Mergers, Market Power, and Market Conditions

description: Retail and wholesale gasoline prices vary over time and across geographic locations due to differences in government policies and other factors that affect demand, costs, and market power. We use a two-equation, reduced-form model to determine the relative importance of these various factors. An increase in the price of crude oil has been virtually the only major factor contributing to a general rise in prices over the last couple of decades. Tax variations and mergers contribute substantially more to geographic price differentials than do price discrimination, cost factors, or pollution controls.
PCA and K-Means decipher genome

description: In this paper, we aim to give a tutorial for undergraduate students studying statistical methods and/or bioinformatics. The students will learn how data visualization can help in genomic sequence analysis. Students start with a fragment of genetic text of a bacterial genome and analyze its structure. By means of principal component analysis they ``discover'' that the information in the genome is encoded by non-overlapping triplets. Next, they learn how to find gene positions. This exercise on PCA and K-Means clustering enables active study of the basic bioinformatics notions. Appendix 1 contains program listings that go along with this exercise. Appendix 2 includes 2D PCA plots of triplet usage in moving frame for a series of bacterial genomes from GC-poor to GC-rich ones. Animated 3D PCA plots are attached as separate gif files. Topology (cluster structure) and geometry (mutual positions of clusters) of these plots depends clearly on GC-content.

description: We make remarks on the Maximum Entropy Method (MEM) for studies of the spectral function of hadronic correlators in finite temperature lattice QCD. We discuss the virtues and subtlety of MEM in the cases that one does not have enough number of data points such as at finite temperature. Taking these points into account, we suggest several tests which one should examine to keep the reliability for the results, and also apply them using mock and lattice QCD data.

subject: observational equivalence

description: This note derives the dynamic programming equation (DPE) to a differentiable Markov Perfect equilibrium in a problem with non-constant discounting and general functional forms. We begin with a discrete stage model and take the limit as the length of the stage goes to 0 to obtain the DPE corresponding to the continuous time problem. We characterize the multiplicity of equilibria under non-constant discounting and discuss the relation between a given equilibrium of that model and the unique equilibrium of a related problem with constant discounting. We calculate the bounds of the set of candidate steady states and we Pareto rank the equilibria.

Tidal Asteroseismology: Possible Evidence of Non-linear Mode Coupling in an Equilibrium State in Kepler Eclipsing Binary KIC 3230227
Creators: name: Guo, Zhao
Publisher: name: arXiv
Year: 2020
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Previously, a series of tidally-excited oscillations were discovered in the eccentric eclipsing binary KIC 3230227. The pulsation amplitudes and phases suggest the observed oscillations are prograde quadruple modes. In this paper, we refine the analysis and extract more oscillation frequencies. We also study the temporal variations of amplitudes and phases and show that almost all modes have stable phases and amplitudes. We then focus on the non-orbital-harmonic oscillations. We consider two formation mechanisms: 1) nonlinear response of the surface convective layer, and 2) nonlinear three/multi-mode coupling. Although the former can explain some of the observed features, we find the latter mechanism is more probable. Assuming that these are coupled modes, the constant amplitude/phase over four years can be explained by either an equilibrium state in the mode coupling or modes undergoing limit cycles with very long periods. The observed frequency detuning and the calculated damping rates of the daughter modes favor the equilibrium-state interpretation. This is verified by integrating the amplitude equations of three-mode coupling. We find that the steady-state relation derived in Weinberg et al., which relates the observed frequency detuning, phase detuning, and mode damping rates, is approximately satisfied for one mode triplet. We also try to identify the azimuthal number of the modes based on the observed mode amplitude ratios and the selection rules in nonlinear three-mode coupling. We discuss further implications of these observations on nonlinear tidal asteroseismology.
