description: A simple generative model of a foraging society generates significant wealth inequalities from identical agents on an equal opportunity landscape. These inequalities arise in both equilibrium and non-equilibrium regimes with some societies essentially never reaching equilibrium. Reproduction costs mitigate inequality beyond their affect on intrinsic growth rate. The highest levels of inequality are found during non-equilibrium regimes. Inequality in dynamic regimes is driven by factors different than those driving steady state inequality. Evolutionary pressures drive the intrinsic growth rate as high as possible, leading to a tragedy of the commons.

description: This dissertation examines two policies that affect women's education, bargaining power, son preference, and awareness of domestic violence in developing countries. The first chapter evaluates a conditional cash transfer program in Bangladesh to identify its impact on the education of multiple generations and explores the pathways behind the impact. The second chapter examines a domestic violence policy in Bangladesh to identify its impact on women's justification of violence.Globally, about 254 million school-aged children are not enrolled in school, weakening their future productivity and slowing the economic development of their societies. The first chapter shows that investment in educating young women is an effective development policy because they also increase their children's education. To identify a causal effect, I use a difference-in-difference and instrumental variable approach to exploit the exogenous variation provided by a program that temporarily made secondary education free for girls in rural Bangladesh. In addition, I explore the causal role of various pathways by which a mother’s education increases her child’s education: marital matching, fertility, labor market participation, bargaining power, and son preference. The paper contributes by providing evidence of education spillovers in a developing country setting, where there is surprisingly little causal evidence. Additionally, it unpacks the multiple pathways through which an increase in the mother’s education contributes to an increase in the child’s education, an aspect previously overlooked in the literature.The second chapter investigates how domestic violence laws impact women’s attitudes toward intimate partner violence (IPV). Around 736 million women worldwide have been victims of domestic violence at least once in their lifetime. Violence can contribute to higher health and economic costs and reduced economic activities. Using the enactment of the Bangladesh Domestic Violence (Prevention and Protection) Act 2010 as a natural experiment and a difference-in-difference approach, I show that the implementation of the law significantly reduced women’s justification of violence. The study provides evidence that laws can change personal beliefs and social norms, even in patriarchal countries with a conservative outlook toward women.Overall, this dissertation highlights the importance of policies affecting women in developing countries.

description: The NASA Discovery mission EPOXI, utilizing the Deep Impact flyby spacecraft, comprises two phases: EPOCh (Extrasolar Planet Observation and Characterization) and DIXI (Deep Impact eXtended Investigation). With EPOCh, we use the 30-cm high resolution visible imager to obtain ultraprecise photometric light curves of known transiting planet systems. We will analyze these data for evidence of additional planets, via transit timing variations or transits; for planetary moons or rings; for detection of secondary eclipses and the constraint of geometric planetary albedos; and for refinement of the system parameters. Over a period of four months, EPOCh observed four known transiting planet systems, with each system observed continuously for several weeks. Here we present an overview of EPOCh, including the spacecraft and science goals, and preliminary photometry results.

The high affinity-low capacity androgen binding protein in the hepatic cystol of streptozotocin diabetic Wistar rats
Creators: name: Rodway, Marie R.
Publisher: name: University of British Columbia
Year: 2010

description: Recently several groups have identified and partially characterized a high affinity-low capacity androgen binding protein (HALC ABP) in the hepatic cytosol of rats, rabbits and humans. In order to further characterize and to identify the physiological control mechanisms of this protein we did a series of studies in Wistar rats. The synthetic androgen methyltrienolone (R1881) was used as the ligand in binding studies. Precipitation with 50% ammonium sulfate resulted in a 2 to 3 fold purification, but did not eliminate the glucocorticoid receptor to which R1881 also binds. Frozen storage, at -80°C has no apparent effect on the hepatic HALC ABP. Studies on sex and age differences showed that R1881 binding was present in mature females and immature rats at less than one-half the concentration found in mature males. Neonatal castration of males appears to decrease or eliminate the HALC ABP in mature rats. No evidence of binding of R1881 to androgen binding proteins in blood was seen . The HALC ABP binding capacity was significantly reduced from control levels in 4 and 10 day streptozotocin (STZ, 60 mg/kg, intravenous) diabetic male Wistar rats; there are no apparent changes in Kd or in steroid specificity. After induction of diabetes with STZ, serum insulin levels are significantly decreased in 24 hours-Testosterone serum levels and triiodothyronine serum levels are significantly decreased 3 days after STZ injection. Dampening of the normal peaks of growth hormone secretion in male rats is evident 18 hours after STZ injection, and continues progressively. These changes correspond to the decrease in binding capacity of the hepatic HALC ABP. If the HALC ABP were regulated by one of these hormones, restoration of their serum levels should have restored the binding capacity of the HALC ABP. Partial restoration of the binding capacity of the prostatic androgen receptor was possible with testosterone or insulin in STZ diabetic rats. Attempted restoration to control levels of the hepatic HALC ABP by treatment of 4 day STZ diabetics with the following hormones was unsuccessful: insulin (protamine zinc insulin, 10 U/kg s.c. daily, or Toronto insulin 15 U/kg s.c. twice daily); testosterone enanthate (1 mg/kg s.c. daily); triiodothyronine (30 μg/kg s.c. daily); or ovine growth hormone (by minipump 0.02 U/hr for 4 days, s.c. 30 μg/dose for 7 daily doses, vena cava catheter 30 μg/dose for 7 daily doses, and tail vein injection 30 μg/dose, for 4 daily dose s). It is concluded that the HALC ABP is not regulated by insulin levels, by testosterone levels, by T₃ levels, or by GH levels or the GH male secretory pattern. Stress appears to cause a decrease in the binding capacity of the HALC ABP in adult male Wistar rats.

description: Recent astronomical observations of both isomers E and Z of imines such as cyanomethanimine, ethanimine and 2-propyn-1-imine, have revealed that the abundances in the ISM of these isomers differ by factors of ~3-10. Several theories have been proposed to explain the observed behavior, but none of them successfully explains the [E]/[Z] ratios. In this work we present a detailed study of the kinetics of the one-step E-Z isomerization reactions of cyanomethanimine, ethanimine and 2-propyn-1-imine under interstellar conditions (in the 10-400 K temperature range). This reaction was previously thought to be non-viable in the ISM due to its associated high-energy barrier (about 13,000 K). In this Letter, we show that considering the multidimensional small curvature tunneling approximation, the tunneling effect enables the isomerization even at low temperatures. This is due to the fact that the representative tunneling energy lies in the vibrational ground state of the least stable isomer up to approximately 150 K, making the reaction constants of the isomerization from the least stable to the most stable isomer basically constant. The predicted [E]/[Z] ratios are almost the same as those reported from the astronomical observations for all imines observed. This study demonstrates that the [E]/[Z] ratio of imines in the ISM strongly depends on their relative stability.

Black hole mass estimates from soft X-ray spectra

description: In the absence of direct kinematic measurements, the mass of an accreting black hole is sometimes inferred from the X-ray spectral parameters of its accretion disk; specifically, from the temperature and normalization of a disk-blackbody model fit. Suitable corrections have to be introduced when the accretion rate approaches or exceeds the Eddington limit. We summarize phenomenological models that can explain the very high state, with apparently higher disk temperatures and lower inner-disk radii. Conversely, ultraluminous X-ray sources often contain cooler disks with large characteristic radii. We introduce another phenomenological model for this accretion state. We argue that a standard disk dominates the radiative output for radii larger than a characteristic transition radius R_c ~ mdot x R_{ISCO}, where mdot is the accretion rate in Eddington units and R_{ISCO} is the innermost stable orbit. For R_{ISCO} < R < R_c, most of the accretion power is released via non-thermal processes. We predict the location of such sources in a luminosity-temperature plot. We conclude that black holes with masses ~ 50-100 Msun accreting at mdot ~ 10-20 may explain the X-ray properties of many ULXs.

description: In this model, a rotor layout was developed, a modal analysis of the object of study was carried out to compare the natural frequencies of axial vibrations with the initial data, a hydrodynamic calculation was carried out to determine the damping coefficients and the coefficients of the attached masses, the natural frequencies of the model were determined. It is shown that the calculation technique used has sufficient accuracy and is applicable to more complex damping systems from the point of view of geometry and design. A series of tests was also carried out on a simplified (single-section) model of the object of study with and without a damping device to verify the correctness of the hydrodynamic part of the problem.

description: $ε$~Eridani is a young planetary system hosting a complex multi-belt debris disk and a confirmed Jupiter-like planet orbiting at 3.48 AU from its host star. Its age and architecture are thus reminiscent of the early Solar System. The most recent study of Mawet et al. 2019, which combined radial velocity (RV) data and Ms-band direct imaging upper limits, started to constrain the planet's orbital parameters and mass, but are still affected by large error bars and degeneracies. Here we make use of the most recent data compilation from three different techniques to further refine $ε$~Eridani~b's properties: RVs, absolute astrometry measurements from the Hipparcos~and Gaia~missions, and new Keck/NIRC2 Ms-band vortex coronagraph images. We combine this data in a Bayesian framework. We find a new mass, $M_b$ = $0.66_{-0.09}^{+0.12}$~M$_{Jup}$, and inclination, $i$ = $77.95_{-21.06}^{\circ+28.50}$, with at least a factor 2 improvement over previous uncertainties. We also report updated constraints on the longitude of the ascending node, the argument of the periastron, and the time of periastron passage. With these updated parameters, we can better predict the position of the planet at any past and future epoch, which can greatly help define the strategy and planning of future observations and with subsequent data analysis. In particular, these results can assist the search for a direct detection with JWST and the Nancy Grace Roman Space Telescope's coronagraph instrument (CGI).

description: The Internet of Things (IoT) is penetrating many facets of our daily life with the proliferation of intelligent services and applications empowered by artificial intelligence (AI). Traditionally, AI techniques require centralized data collection and processing that may not be feasible in realistic application scenarios due to the high scalability of modern IoT networks and growing data privacy concerns. Federated Learning (FL) has emerged as a distributed collaborative AI approach that can enable many intelligent IoT applications, by allowing for AI training at distributed IoT devices without the need for data sharing. In this article, we provide a comprehensive survey of the emerging applications of FL in IoT networks, beginning from an introduction to the recent advances in FL and IoT to a discussion of their integration. Particularly, we explore and analyze the potential of FL for enabling a wide range of IoT services, including IoT data sharing, data offloading and caching, attack detection, localization, mobile crowdsensing, and IoT privacy and security. We then provide an extensive survey of the use of FL in various key IoT applications such as smart healthcare, smart transportation, Unmanned Aerial Vehicles (UAVs), smart cities, and smart industry. The important lessons learned from this review of the FL-IoT services and applications are also highlighted. We complete this survey by highlighting the current challenges and possible directions for future research in this booming area.

description: The QCD description of exclusive decays of the $Λ_b$ baryon involves hadronic matrix elements of non-local light ray operators, the light-cone distribution amplitudes. We introduce the complete set of three--quark distribution amplitudes and calculate the renormalization scale dependence for the leading twist. At leading order in the strong coupling the evolution is driven by pairwise two--quark interactions: heavy--light involving Sudakov logarithms as in the B-meson case, and light--light as in light mesons. We solve the evolution equation and show that its main effect is to generate a radiative tail extending to high energies. Finally, we present simple models for the distribution amplitudes based on QCD sum rules, and study the effect of the evolution on these models.

description: I report on observations of the z=0.01 dwarf galaxy SBS1543+593 which is projected onto the background QSO HS1543+5921. As a star-forming galaxy first noted in emission, this dwarf is playing a pivotal role in our understanding of high-redshift galaxy populations, because it also gives rise to a Damped Lyman Alpha system. This enabled us to analyze, for the first time, the chemical abundance of $α$ elements in a Damped Lyman Alpha galaxy using both, emission and absorption diagnostics. We find that the abundances agree with one another within the observational uncertainties. I discuss the implications of this result for the interpretation of high-redshift galaxy observations. A catalog of dwarf-galaxy--QSO projections culled from the Sloan Digital Sky Survey is provided to stimulate future work.

The quantification of upland runoff for subsurface drainage design
Creators: name: Runesson, Deborah
Publisher: name: University of British Columbia
Year: 2010

description: Accurate upland runoff and peak flow estimates are crucial for successful subsurface drainage design in adjacent lowland agricultural regions. Three techniques used in drainage design, namely the SCS Curve Number approach for runoff estimation, and the SCS unit hydrograph procedure and the Rational formula for peak flow estimation were evaluated. A small upland research watershed was established at Agriculture Canada's Agassiz Research Station, Farm #2, in the eastern end of the Lower Fraser Valley of British Columbia. The use of digital elevation models to assist in watershed analysis was reviewed through the development of a model for the Research watershed. Findings showed that the SCS Curve Number approach underestimated runoff. The Rational formula provided the best estimates of peak flow. The use of a digital elevation model provided required parameters for the various methods tested, and showed high potential for further use in watershed quantification.

Spatiotemporal correlations in entangled photons generated by spontaneous parametric down conversion

description: In most configurations aimed at generating entangled photons based on spontaneous parametric down conversion (SPDC), the generated pairs of photons are required to be entangled in only one degree of freedom. Any distinguishing information coming from the other degrees of freedom that characterize the photon should be suppressed to avoid correlations with the degree of freedom of interest. However, this suppression is not always possible. Here, we show how the frequency information available affects the purity of the two-photon state in space, revealing a correlation between the frequency and the space degrees of freedom. This correlation should be taken into account to calculate the total amount of entanglement between the photons.

description: At B3LYP level of theory, we predict that the half-metallicity in zigzag edge graphene nanoribbon (ZGNR) can be realized when an external electric field is applied across the ribbon. The critical electric field to induce the half-metallicity decreases with the increase of the ribbon width. Both the spin polarization and half-metallicity are removed when the edge state electrons fully transferred from one side to the other under very strong electric field. The electric field range under which ZGNR remain half-metallic increases with the ribbon width. Our study demonstrates a rich field-induced spin polarization behavior, which may leads to some important applications in spinstronics.

description: Accurately understanding the interior structure of extra-solar planets is critical for inferring their formation and evolution. The internal density distribution of a planet has a direct effect on the star-planet orbit through the gravitational quadrupole field created by the rotational and tidal bulges. These quadrupoles induce apsidal precession that is proportional to the planetary Love number ($k_{2p}$, twice the apsidal motion constant), a bulk physical characteristic of the planet that depends on the internal density distribution, including the presence or absence of a massive solid core. We find that the quadrupole of the planetary tidal bulge is the dominant source of apsidal precession for very hot Jupiters ($a \lesssim 0.025$ AU), exceeding the effects of general relativity and the stellar quadrupole by more than an order of magnitude. For the shortest-period planets, the planetary interior induces precession of a few degrees per year. By investigating the full photometric signal of apsidal precession, we find that changes in transit shapes are much more important than transit timing variations. With its long baseline of ultra-precise photometry, the space-based \emph{Kepler} mission can realistically detect apsidal precession with the accuracy necessary to infer the presence or absence of a massive core in very hot Jupiters with orbital eccentricities as low as $e \simeq 0.003$. The signal due to $k_{2p}$ creates unique transit light curve variations that are generally not degenerate with other parameters or phenomena. We discuss the plausibility of measuring $k_{2p}$ in an effort to directly constrain the interior properties of extra-solar planets.

description: The dynamic scaling properties of the one dimensional Burgers equation are expected to change with the inclusion of additional conserved degrees of freedom. We study this by means of 1-D driven lattice gas models that conserve both mass and momentum. The most elementary version of this is the Arndt-Heinzel-Rittenberg (AHR) process, which is usually presented as a two species diffusion process, with particles of opposite charge hopping in opposite directions and with a variable passing probability. From the hydrodynamics perspective this can be viewed as two coupled Burgers equations, with the number of positive and negative momentum quanta individually conserved. We determine the dynamic scaling dimension of the AHR process from the time evolution of the two-point correlation functions, and find numerically that the dynamic critical exponent is consistent with simple Kardar-Parisi-Zhang (KPZ) type scaling. We establish that this is the result of perfect screening of fluctuations in the stationary state. The two-point correlations decay exponentially in our simulations and in such a manner that in terms of quasi-particles, fluctuations fully screen each other at coarse grained length scales. We prove this screening rigorously using the analytic matrix product structure of the stationary state. The proof suggests the existence of a topological invariant. The process remains in the KPZ universality class but only in the sense of a factorization, as $({KPZ})^2$. The two Burgers equations decouple at large length scales due to the perfect screening.

description: As part of preparations for a southern sky search for faint Milky Way dwarf galaxy satellites, we report the discovery of a stellar overdensity in the Sloan Digital Sky Survey Data Release 5, lying at an angular distance of only 1.5 degrees from the recently discovered Bo{ö}tes dwarf. The overdensity was detected well above statistical noise by employing a sophisticated data mining algorithm and does not correspond to any catalogued object. Overlaid isochrones using stellar population synthesis models show that the color-magnitude diagram of that region has the signature of an old (12 Gyr), metal-poor (${\rm Fe/H}\approx-2.0$) stellar population at a tentative distance of 60 kpc, evidently the same heliocentric distance as the Boötes dwarf. We estimate the new object to have a total magnitude of $M_{V}\sim-3.1\pm1.1$ mag and a half-light radius of $r_{h}=4'.1\pm1'.6$ ($72\pm28$ pc) placing it in an apparent $40

Near-Field Microlensing from Wide-Field Surveys

Subjects: subject: Astrophysics (astro-ph)

description: We estimate the rate of near-field microlensing events expected from all-sky surveys and investigate the properties of these events. Under the assumption that all lenses are composed of stars, our estimation of the event rate ranges from Γ_{tot}~0.2 yr^{-1}$ for a survey with a magnitude limit of V_{lim}=12 to Γ_{tot}~20 yr^{-1} for a survey with V_{lim}=18. We find that the average distances to source stars and lenses vary considerably depending on the magnitude limit, while the dependencies of the average event time scale and lens-source transverse speed are weak and nearly negligible, respectively. We also find that the the average lens-source proper motion of events expected even from a survey with V_{lim}=18 would be >~ 40 mas yr^{-1}, implying that the source and lens of a significant fraction of near-field events could be resolved from high-resolution follow-up observations. From the investigation of the variation of the event characteristics depending on the position of the sky, we find that the average distances to source stars and lenses become shorter, the lens-source transverse speed increases, and the time scale becomes shorter as the the galactic latitude of the field increases. Due to the concentration of events near the galactic plane, we find that >~ 50 % of events would be detected in the field with b <= 20^\circ.

description: We consider a superintegrable Hamiltonian system in a two-dimensional space with a scalar potential that allows one quadratic and one cubic integral of motion. We construct the most general cubic algebra and we present specific realizations. We use them to calculate the energy spectrum. All classical and quantum superintegrable potentials separable in Cartesian coordinates with a third order integral are known. The general formalism is applied to quantum reducible and irreducible rational potentials separable in Cartesian coordinates in E2. We also discuss these potentials from the point of view of supersymmetric and PT-symmetric quantum mechanics.

description: In the domain of software engineering, our efforts as researchers to advise industry on which software practices might be applied most effectively are limited by our lack of evidence based information about the relationships between context and practice efficacy. In order to accumulate such evidence, a model for context is required. We are in the exploratory stage of evolving a model for context for situated software practices. In this paper, we overview the evolution of our proposed model. Our analysis has exposed a lack of clarity in the meanings of terms reported in the literature. Our base model dimensions are People, Place, Product and Process. Our contributions are a deepening of our understanding of how to scope contextual factors when considering software initiatives and the proposal of an initial theoretical construct for context. Study limitations relate to a possible subjectivity in the analysis and a restricted evaluation base. In the next stage in the research, we will collaborate with academics and practitioners to formally refine the model.

description: The first low radio frequency (<1.4 GHz) detection of the outburst of the recurrent nova RS Ophiuchi is presented in this letter. Radio emission was detected at 0.61 GHz on day 20 with a flux density of ~48 mJy and at 0.325 GHz on day 38 with a flux density of ~ 44 mJy. This is in contrast with the 1985 outburst when it was not detected at 0.327 GHz even on day 66. The emission at low radio frequencies is clearly non-thermal and is well-explained by a synchrotron spectrum of index alpha ~ -0.8 (S propto nu^alpha) suffering foreground absorption due to the pre-existing, ionized, warm, clumpy red giant wind. The absence of low frequency radio emission in 1985 and the earlier turn-on of the radio flux in the current outburst are interpreted as being due to higher foreground absorption in 1985 compared to that in 2006, suggesting that the overlying wind densities in 2006 are only ~30% of those in 1985.

description: We develop sequestered inflation models, where inflation occurs along flat directions in supergravity models derived from type IIB string theory. It is compactified on a ${\mathbb{T}^6 \over \mathbb{Z}_2 \times \mathbb{Z}_2}$ orientifold with generalized fluxes and O3/O7-planes. At Step I, we use flux potentials which 1) satisfy tadpole cancellation conditions and 2) have supersymmetric Minkowski vacua with flat direction(s). The 7 moduli are split into heavy and massless Goldstone multiplets. At Step II we add a nilpotent multiplet and uplift the flat direction(s) of the type IIB string theory to phenomenological inflationary plateau potentials: $α$-attractors with 7 discrete values $3α= 1, 2, 3, ..., 7$. Their cosmological predictions are determined by the hyperbolic geometry inherited from string theory. The masses of the heavy fields and the volume of the extra dimensions change during inflation, but this does not affect the inflationary dynamics.

description: SORLA, the protein encoded by SORL1 gene, has an important role in recycling cargo proteins to the cell surface. While SORLA loss-of-function variants occur almost exclusively in Alzheimer's disease cases, the majority of SORL1 variants are missense variants that are individually rare and can have individual mechanisms how they impair SORLA function as well as have individual effect size on disease risk. However, since carriers mostly come from small pedigrees, it is challenging to determine variant penetrance, leaving clinical significance associated with most missense variants unclear. In this article, we present functional approaches to evaluate the pathogenicity of a SORL1 variant p.D1105H. First, we generated our mutant receptor by inserting the D1105H variant into the full-length SORLA-WT receptor. Then using Western blot analysis we quantified the effect of the mutation on maturation and shedding of the receptor for transfected cells, and finally applied a flow cytometry approach to quantify SORLA expression at the cell surface. The results showed decreased maturation, decreased shedding, and decreased cell surface expression of D1105H compared to wild-type SORLA. We propose how these approaches can be used to functionally assess the pathogenicity of SORL1 variants in the future.This article is part of a discussion meeting issue ‘Understanding the endosomal network in neurodegeneration’.
