When is Arsenic Poisoning Prevention Unaffordable? Determining the EPA 'Affordability Criteria' for Small Water Systems Under the 1996 Clean Drinking Water Act

description: Why would anyone want lower quality drinking water? The Safe Drinking Water Act allows an "affordability, variance technology, small system variance exemption" to the drinking water standards based on a supply side argument. It assumes small drinking water systems have significant diseconomies of scale in meeting the maximum contaminant levels. We can test this assumption by examining the cost of compliance technologies by system size developed by the Environmental Protection Agency to meet the mcl for arsenic. The data show that the least costly arsenic reduction technology to meet the current mcl of 10 parts per billion (ppb) is modify coagulation/filtration. This technology is also six to seven times more expensive to implement for very small systems (50 people or less) than for the small and medium size systems. At least for very small drinking water systems the arsenic case supports the assumption of diseconomies of small scale production. On the demand side, Albert Hirschman provides a theory that allows us to look at the tradeoff between the prices and the varieties of quality, e.g., mcl, for two types of consumers for a given quantity of drinking water. We describe the EPA affordability criterion. Then we analyze it in terms of changes in consumer surplus and economic rent from welfare theory. Finally we suggest an alternative criterion that we believe is more consistent with economic theory.

Non-linear Structure Formation in Cosmologies with Early Dark Energy

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: We argue that a few per cent of "Early Dark Energy" can be detected by the statistics of nonlinear structures. The presence of Dark Energy during linear structure formation is natural in models where the present tiny Dark-Energy density is related to the age of the Universe rather than a new fundamental small parameter. Generalisation of the spherical collapse model shows that the linear collapse parameter delta_c is lowered. The corresponding relative enhancement of weak gravitational lensing on arc-minute scales lowers the value of sigma_8 inferred from a given lensing amplitude as compared to Lambda-CDM. In presence of Early Dark Energy, structures grow slower, such that for given sigma_8 the number of galaxies and galaxy clusters is substantially increased at moderate and high redshift. For realistic models, the number of clusters detectable through their thermal Sunyaev-Zel'dovich effect at redshift unity and above, e.g. with the Planck satellite, can be an order of magnitude larger than for Lambda-CDM.

description: Noble gas and liquid detectors rely on high chemical purity for successful operation. While gaseous purification has emerged as a reliable method of producing high-purity noble fluids, the requirement for large mass flows drives the development of liquid-phase purification. We constructed a medium-scale liquid argon (LAr) purification system based on a copper catalyst and 4 A molecular sieve capable of purifying 1 t of commercial LAr 5.0 to a long effective triplet lifetime of $τ_3 \sim 1.3 μ$s. We further demonstrate that a quenched effective triplet lifetime of $τ_3 \sim 1 μ$s, due to contamination by air, can be recovered in loop-mode purification to $τ_3 \sim 1.3 μ$s after > 20 volume exchanges.

description: Optical rotation, a form of optical activity, is a phenomenon employed in various metrological applications and industries including chemical, food, and pharmaceutical. In naturally-occurring, as well as structured media, the integrated effect is, however, typically small. Here, we demonstrate that, by exploiting the inherent and stable spin-orbit interaction of orbital angular momentum fiber modes, giant, scalable optical activity can be obtained, and that we can use this effect to realize a new type of wavemeter by exploiting its optical rotary dispersion. The device we construct provides for an instantaneous wavelength-measurement technique with high resolving power $R =3.4 \times 10^6$ (i.e. resolution $< 0.3 pm$ at $1-μm$ wavelengths) and can also detect spectral bandwidths of known lineshapes with high sensitivity.

description: This study is primarily meant to develop a methodology to detect early-stage Parkinsonism when the symptoms may not be consistent or visible. The current clinical diagnosis methods identify Parkinsonism only when symptoms are advanced/visible and by this point majority of the neurons are degenerated. Early diagnosis would help clinicians to start the correct treatment procedure right from the beginning thereby reducing the severity of symptoms in later stages. Thus, the patients will have a better quality of life with reduced treatment costs.

description: We present far-ultraviolet observations of IC 63, an emission/reflection nebula illuminated by the B0.5IV star gamma Cassiopeia, located 1.3 pc from the nebula. Molecular hydrogen fluorescence was detected first in IC 63 by IUE and later at shorter wavelengths by ORFEUS. Here we present Far Ultraviolet Spectroscopic Explorer (FUSE) observations towards three locations in the nebula, complemented by Hopkins Ultraviolet Telescope (HUT) data on the central nebular position. In addition, we present a sounding rocket calibration of a FUSE spectrum of gamma Cas. Molecular hydrogen fluorescence is detected in all three FUSE pointings. The intensity of this emission as well as the contributions from other species are seen to vary with position. The absolute flux calibration of the sounding rocket data allows us to reliably predict the radiation field incident on IC 63. We use these data to test models of the fluorescent process. Our modeling resolves the perceived discrepancy between the existing ultraviolet observations and achieves a satisfactory agreement with the H_2 rotational structure observed with FUSE.

The effects of prenatal exposure to alcohol, tobacco and other risks on children’s health, behaviour and academic abilities
Creators: name: George, Mary Anne
Publisher: name: University of British Columbia
Year: 2009

description: Maternal behaviours during pregnancy may contribute to unhealthy child development. Previous research has linked adverse outcomes to prenatal exposure to heavy alcohol use, to tobacco use, and to socioeconomic background. Health professionals have been responsive because of the preventable nature of these risks. This research examined the impact on children from diverse backgrounds who had been exposed prenatally to varying amounts of alcohol and tobacco, or both. It further assessed the additive effects of these risks. The Vancouver Island Pregnancy Follow-up Study is population-based. It examined the health, academic abilities and behaviours of 8-year old children born over a 1-year period in a pre-defined area of British Columbia (n=3,659). It attempted to find the total randomly selected sample (n=403), with the result that 65.7% families (n=265) participated, 25.8% were not located, 5.5% refused, and 3.0% were not available. The data sources were children, who were tested on their academic abilities using the WRAT-3, and their parents and teachers who were interviewed regarding the child's health, behaviour and school performance. Results with respect to academic abilities showed that only reading scores were associated with prenatal alcohol exposure. Reading and spelling ability scores were associated with the combination of being prenatally exposed to alcohol and having a father with low education. Poorer health ratings were associated with prenatal alcohol exposure, with the combination of pre- and postnatal tobacco exposure, and with lower socioeconomic background. All three independent variables were associated with behaviour scores. Children of heavy drinkers had higher scores on the total behaviour scale and on five subscales. Prenatal tobacco exposure was associated with higher Conduct Disorder scores. The findings are consistent with other longitudinal studies. In the absence of other risk factors, there was little evidence of associations between prenatal exposure to moderate alcohol use or risk level and academic abilities, health ratings, or behavioural problems. It may be productive to take ecological approaches to understanding children's behavioural, academic and health problems in the context of their socioeconomic conditions and their exposure to alcohol prenatally and to tobacco both prenatally and postnatally.

description: This article describes a simple Susceptible Infected Recovered (SIR) model fitting with COVID-19 data for the month of march 2020 in New York (NY) state. The model is a classical SIR, but is non-autonomous; the rate of susceptible people becoming infected is adjusted over time in order to fit the available data. The death rate is also secondarily adjusted. Our fitting is made under the assumption that due to limiting number of tests, a large part of the infected population has not been tested positive. In the last part, we extend the model to take into account the daily fluxes between New Jersey (NJ) and NY states and fit the data for both states. Our simple model fits the available data, and illustrates typical dynamics of the disease: exponential increase, apex and decrease. The model highlights a decrease in the transmission rate over the period which gives a quantitative illustration about how lockdown policies reduce the spread of the pandemic. The coupled model with NY and NJ states shows a wave in NJ following the NY wave, illustrating the mechanism of spread from one attractive hot spot to its neighbor. }

description: Imposing curvature and monotonocity restrictions always has been a vexing problem for applied economists. We present an estimation methodology for more efficiently estimating flexible functional forms subject to "regional", as opposed to "local" or "global", regularity conditions. The technique involves a Markov Chain Monte Carlo sampler to ensure consistency over a predefined connected set of the regressor space. Numerical examples demonstrate the advantages and technical feasibility of our new approach.

description: There is currently a severe discrepancy between theoretical models of dust formation in core-collapse supernovae (CCSNe), which predict $\gtrsim 0.01$ M$_\odot$ of ejecta dust forming within $\sim 1000$ days, and observations at these epochs, which infer much lower masses. We demonstrate that, in the optically thin case, these low dust masses are robust despite significant observational and model uncertainties. For a sample of 11 well-observed CCSNe, no plausible model reaches carbon dust masses above $10^{-4}$ M$_\odot$, or silicate masses above $\sim 10^{-3}$ M$_\odot$. Optically thick models can accommodate larger dust masses, but the dust must be clumped and have a low ($<0.1$) covering fraction to avoid conflict with data at optical wavelengths. These values are insufficient to reproduce the observed infrared fluxes, and the required covering fraction varies not only between SNe but between epochs for the same object. The difficulty in reconciling large dust masses with early-time observations of CCSNe, combined with well-established detections of comparably large dust masses in supernova remnants, suggests that a mechanism for late-time dust formation is necessary.

Last passage percolation and limit theorems in Barak-Erdős directed random graphs and related models

description: We consider directed random graphs, the prototype of which being the Barak-Erdős graph $\vec G(\mathbb Z, p)$, and study the way that long (or heavy, if weights are present) paths grow. This is done by relating the graphs to certain particle systems that we call Infinite Bin Models (IBM). A number of limit theorems are shown. The goal of this paper is to present results along with techniques that have been used in this area. In the case of $\vec G(\mathbb Z, p)$ the last passage percolation constant $C(p)$ is studied in great detail. It is shown that $C(p)$ is analytic for $p>0$, has an interesting asymptotic expansion at $p=1$ and that $C(p)/p$ converges to $e$ like $1/(\log p)^2$ as $p \to 0$. The paper includes the study of IBMs as models on their own as well as their connections to stochastic models of branching processes in continuous or discrete time with selection. Several proofs herein are new or simplified versions of published ones. Regenerative techniques are used where possible, exhibiting random sets of vertices over which the graphs regenerate. When edges have random weights we show how the last passage percolation constants behave and when central limit theorems exist. When the underlying vertex set is partially ordered, new phenomena occur, e.g., there are relations with last passage Brownian percolation. We also look at weights that may possibly take negative values and study in detail some special cases that require combinatorial/graph theoretic techniques that exhibit some interesting non-differentiability properties of the last passage percolation constant. We also explain how to approach the problem of estimation of last passage percolation constants by means of perfect simulation.

description: We investigate the longitudinal spin relaxation arising due to spin-flip transitions accompanied by phonon emission in quantum dots where the strength of the Rashba spin-orbit coupling is a random function of the lateral (in-plane) coordinate on the spatial nanoscale. In this case the Rashba contribution to the spin-orbit coupling cannot be completely removed by applying a uniform external bias across the quantum dot plane. Due to the remnant random contribution, the spin relaxation rate cannot be decreased by more than two orders of magnitude even when the external bias fully compensates the regular part of the spin-orbit coupling.

Using the generalized Lanczos equations we explored the energy conditions at the wormhole's throat along with the traversability condition. We determined the stability regions when the wormhole configurations are surrounded by different bulk sources and obtained that the stability regions are considerably modified due to the non-trivial dependence of the Rastall parameter in the effective potential energy.

Ultra-Luminous X-ray Sources: Evidence for Very Efficient Formation of Population III Stars Contributing to the Cosmic Near-Infrared Background Excess?

subject: FOS: Physical sciences

description: Accumulating evidence indicates that some of ultra-luminous X-ray sources (ULXs) are intermediate mass black holes (IMBHs), but the formation process of IMBHs is unknown. One possibility is that they were formed as remnants of population III (Pop III) stars, but it has been thought that the probability of being an ULX is too low for IMBHs distributed in galactic haloes to account for the observed number of ULXs. Here we show that the number of ULXs can be explained by such halo IMBHs passing through a dense molecular cloud, if Pop III star formation is very efficient as recently suggested by the excess of the cosmic near-infrared background radiation that cannot be accounted for by normal galaxy populations. We calculate the luminosity function of X-ray sources in our scenario and find that it is consistent with observed data. Our scenario can explain that ULXs are preferentially found at outskirts of large gas concentrations in star forming regions. A few important physical effects are pointed out and discussed, including gas dynamical friction, radiative efficiency of accretion flow, and radiative feedback to ambient medium. ULXs could last for ~10^{5-6} yr to emit a total energy of ~10^{53} erg, which is sufficient to power the ionized expanding nebulae found by optical observations.

description: One of the advantages of the finite energy sum rules is the fact that every operator in the operator product expansion series can be selected individually by the use of an appropriate kernel function which removes other operator poles. This characteristic is maintained by QCD systems in the presence of external homogeneous magnetic field, providing interesting information about the magnetic evolution of QCD and hadronic parameters. In this work finite energy sum rules are applied on QCD in the light quark sector, combining axial and pseudoscalar channels in the presence of an external homogeneous magnetic field, obtaining the magnetic evolution of the light quark masses, pion mass, the pion decay constant, the gluon condensate and the continuum hadronic threshold.

description: We show how the collapse of an energy scale in a quantum critical metal can lead to physics beyond the weak-field limit usually used to compute transport quantities. For a density-wave transition we show that the presence of a finite magnetic field at the critical point leads to discontinuities in the transport coefficients as temperature tends to zero. The origin of these discontinuities lies in the breakdown of the weak field Jones-Zener expansion which has previously been used to argue that magneto-transport coefficients are continuous at simple quantum critical points. The presence of potential scattering and magnetic breakdown rounds the discontinuities over a window determined by tau Delta < 1 where Delta is the order parameter and tau is the quasiparticle elastic lifetime.

description: Salmonellosis in people is a costly disease, much of it occurring because of food associated exposure. We develop a farm-to-fork model which estimates the pork associated Salmonella risk and human health costs. This analysis focuses on the components of the pork production chain up to the point of producing a chilled pork carcass. Sensitivity and scenario analysis show that changes that occur in Salmonella status during processing are substantially more important for human health risk and have a higher benefit/cost ratio for application of strategies that control Salmonella compared with on-farm strategies.

description: Methyl Bromide in the United States is supplied by only four firms (two producers and two importers) who reap windfall profits from MB restrictions. Since 1992 we estimate that over $300 million in cumulative windfall profits have resulted from restrictions on Methyl Bromide and currently run between $65 to $80 million annually. We examine the factors that influenced this price rise, the changes in quota premiums and deadweight losses under trade and no-trade scenarios; and how methods to capture and redistribute windfall profits will alter efficiency and equity.

description: In this article we focus on the effects of preferential trade arrangements on agricultural trade and agricultural income. Given the large number of preferential trade arrangements and complex interactions among them, we attempt to find out whether preferential trade arrangements are beneficial to agricultural trade and income, and are an effective tool to liberalize agricultural trade. The findings suggest that preferential trade arrangements with some exceptions tend to expand agricultural trade and improve agricultural income.

description: Entropic uncertainty relations play an important role in both fundamentals and applications of quantum theory. Although they have been well-investigated in quantum theory, little is known about entropic uncertainty in generalized probabilistic theories (GPTs). The current study explores two types of entropic uncertainty relations, preparation and measurement uncertainty relations, in a class of GPTs which can be considered generalizations of quantum theory. Not only a method for obtaining entropic preparation uncertainty relations but also an entropic measurement uncertainty relation similar to the quantum one by Buscemi et al. [Phys. Rev. Lett., 112, 050401] are proved in those theories. It manifests that the entropic structure of uncertainty relations in quantum theory is more universal. Concrete calculations of our relations in GPTs called the regular polygon theories are also demonstrated.

description: Farmland values in the United States represent a major component of the farm sector balance sheet. The linkage between farmland values and agricultural debt has typically been ignored in the literature. This paper attempts to make two contributions to our understanding of farmland prices. First, building on established literature, this study examines the role of debt solvency and government payments in farmland valuation. Second, from a methodological standpoint, this study incorporates both the nonstationarity dimension of farmland prices and the panel structure of the data relying on recent advances in econometric literature.

description: In this work we propose a tightly-coupled Extended Kalman Filter framework for IMU-only state estimation. Strap-down IMU measurements provide relative state estimates based on IMU kinematic motion model. However the integration of measurements is sensitive to sensor bias and noise, causing significant drift within seconds. Recent research by Yan et al. (RoNIN) and Chen et al. (IONet) showed the capability of using trained neural networks to obtain accurate 2D displacement estimates from segments of IMU data and obtained good position estimates from concatenating them. This paper demonstrates a network that regresses 3D displacement estimates and its uncertainty, giving us the ability to tightly fuse the relative state measurement into a stochastic cloning EKF to solve for pose, velocity and sensor biases. We show that our network, trained with pedestrian data from a headset, can produce statistically consistent measurement and uncertainty to be used as the update step in the filter, and the tightly-coupled system outperforms velocity integration approaches in position estimates, and AHRS attitude filter in orientation estimates.

description: In this Letter we report on lateral diffusion measurements of excitons at low temperature in double quantum wells of various widths. The structure is designed so that excitons live up to 30 $μ$s and diffuse up to 500 $μ$m. Particular attention is given to establishing that the transport occurs by exciton motion. The deduced exciton diffusion coefficients have a very strong well-width dependence, and obey the same power law as the diffusion coefficient for electrons.

description: This paper investigates the scope of the unit value problem in household level expenditure survey data. I test whether self-reported prices vary with covariates thought to be important in household demand behavior. The paper then measures expenditure elasticity of quality for 196 different food aggregates. Approximately half of the expenditure elasticities estimated are significantly different from zero. Finally, a generalization of the standard quality demand regression is proposed, in which the expenditure elasticity of quality is allowed to vary over the range of total food expenditure. Some food aggregates display significant nonlinearities.

description: Secure ranging refers to the capability of upper-bounding the actual physical distance between two devices with reliability. This is essential in a variety of applications, including to unlock physical systems. In this work, we will look at secure ranging in the context of ultra-wideband impulse radio (UWB-IR) as specified in IEEE 802.15.4z (a.k.a. 4z). In particular, an encrypted waveform, i.e. the scrambled timestamp sequence (STS), is defined in the high rate pulse repetition frequency (HRP) mode of operation in 4z for secure ranging. This work demonstrates the security analysis of 4z HRP when implemented with an adequate receiver design and shows the STS waveform can enable secure ranging. We first review the STS receivers adopted in previous studies and analyze their security vulnerabilities. Then we present a reference STS receiver and prove that secure ranging can be achieved by employing the STS waveform in 4z HRP. The performance bounds of the reference secure STS receiver are also characterized. Numerical experiments corroborate the analyses and demonstrate the security of the reference STS receiver.

description: Americans are becoming more health conscious and more obese. The food industry attempts to capitalize on both of these current trends. In advance of government mandate, the dominant leader in the cracker industry introduced a trans fatty acid label to its products. The impact on demand of the voluntary introduction of this label varies across metropolitan area and depends on health-related media coverage, both local and national, and health attitudes of these metropolitan areas.
