description: We investigate the systematic variation of the [OII]3727/Halpha flux line ratio as a function of various galaxy properties, i.e., luminosity, metallicity, reddening, and excitation state, for a sample of 1124 emission-line galaxies, with a mean redshift z ~ 0.06, drawn from the Two Degree Field Galaxy Redshift Survey. The mean observed and extinction-corrected emission-line flux ratios agree well with the values derived from the $B$-band selected Nearby Field Galaxy Survey galaxy sample, but are significantly different from the values obtained from the Halpha-selected Universidad Complutense de Madrid Survey galaxy sample. This is because the different selection criteria applied in these surveys lead to a significant difference in the mean extinction and metallicity of different samples. We use the R_{23} parameter to estimate the gas-phase oxygen abundance and find that the extinction-corrected [OII]3727/Halpha ratio depends on the oxygen abundance. For 12+log(O/H)>8.4, we confirm that the emission-line ratio decreases with increasing metallicity. We have extended the relationship further to the metal-poor regime, 12+log(O/H)< 8.4, and find that the correlation between the extinction-corrected [OII]3727/Halpha ratio and the metallicity reverses in comparison to the relationship for metal-rich galaxies. For metal-poor galaxies, in contrast with metal-rich ones, the variation of extinction-corrected [OII]3727/Halpha ratio is correlated with the ionization states of the interstellar gas.

description: We propose an efficient scheme for constructing arbitrary 2-D cluster states using probabilistic entangling quantum gates.In our scheme, the 2-D cluster state is constructed with star-like basic units generated from 1-D cluster chains.By applying parallel operations, the process of generating 2-D (or higher dimensional) cluster states is significantly accelerated, which provides an efficient way to implement realistic one way quantum computers.

description: Proteresis, a complementary effect to well-known hysteresis, is an interesting phenomenon to be explored. As we know, the hysteric device is a bistable switch whose states depend on the system's history whereas the proteretic device states' depend on the future. Though an all-optical implementation of the hysteric device has been demonstrated but its complementary behavior has yet to be contrived. Therefore, this work presents the design and development of an all-optical proteretic system using semiconductor ring lasers. The design was achieved by providing a constraint feedforward path to a hysteric feedback system. Additionally, the role of various parameters was studied in order to achieve proteresis. It is observed that the proteretic effect can be achieved only for specific conditions otherwise the system behaves as a traditional hysteric device. The experimental results match well with the theoretical Simulink results.

description: We present the results of a pilot Hubble Space Telescope (HST) imaging study of the host galaxies of ten quasars from the Sloan Digital Sky Survey Reverberation Mapping (SDSS-RM) project. Probing more than an order of magnitude in BH and stellar masses, our sample is the first statistical sample to study the BH-host correlations beyond z>0.3 with reliable BH masses from reverberation mapping rather than from single-epoch spectroscopy. We perform image decomposition in two HST bands (UVIS-F606W and IR-F110W) to measure host colors and estimate stellar masses using empirical relations between broad-band colors and the mass-to-light ratio. The stellar masses of our targets are mostly dominated by a bulge component. The BH masses and stellar masses of our sample broadly follow the same correlations found for local RM AGN and quiescent bulge-dominant galaxies, with no strong evidence of evolution in the M_BH-M_*,bulge relation to z~0.6. We further compare the host light fraction from HST imaging decomposition to that estimated from spectral decomposition. We found a good correlation between the host fractions derived with both methods. However, the host fraction derived from spectral decomposition is systematically smaller than that from imaging decomposition by ~30%, indicating different systematics in both approaches. This study paves the way for upcoming more ambitious host galaxy studies of quasars with direct RM-based BH masses at high redshift.

description: Genetically modified (GM) foods have caused many controversies. One important controversy relates to tolerance - the impurity rate that is tolerated before a commodity must be labeled as genetically modified. Currently, the United States does not have a specific tolerance or threshold level for GM foods. This paper uses experimental auctions to determine consumers' acceptance of non-GM foods with zero, 1 percent, and 5 percent tolerance for genetically modified material. Our results indicate that consumers would pay less for food that tolerates GM material, but the discount is not significantly different for foods with 1-percent and 5-percent GM content.

The Story Behind the Post-War Decline in Women's Housework: Prices, Income, Family Size, and Technology Effects in a Demand System

description: This paper applies production theory to define a new set of inputs for U.S. households over the post-World War II period and uses newly constructed data on some of these inputs to fit a complete household-demand system, including inputs of women's and men's housework, and seven other input groups. The econometric results yield plausible price and income elasticities. Women's and men's housework are shown to be complements, rather than substitutes, but the other seven input categories are substitutes for women's housework. Since the price of all inputs, except for men's housework, has fallen significantly relative to the price of women's time over the post-war period, substitution away from women's household work is a major factor in its decline over the study period. Much of this decline, however, occurred from 1948 to 1980. Although the number of children under age 5 per household grew from 1948 to 1960 by 25 percentage points, family size declined from 1960 to 1985 by 27 percentage points and contributed to the post-60s decline in the demand for women's housework. The parameters of the demand system are also used to make some standard of living comparisons for the post-war period.

description: In this work, we investigate the effect of Ni concentration on several shielding properties of $Nd_{0.6}Sr_{0.4}Mn_{1-y}Ni_{y}O_{3}$ (0.00 $\leq$ y $\leq$ 0.20) perovskite ceramic for possible use as radiation shielding materials. X-ray diffraction (XRD) analysis revealed that these ceramics have the orthorhombic structure with group space Pnma over a wide range of Ni-substitutions. Moreover, the analysis showed a nearly linear decrease in the lattice parameters and the unit cell volume (V) causing a gradual increase in the packing density with increasing Ni concentration. The shielding features for photons, neutrons, and protons of all ceramic samples were assessed. The mass attenuation coefficient (MAC) was computed at 0.1, 0.6, 1.25, 5 and 15 MeV by utilizing (MCNP) (version 5.0); the results were compared with the corresponding values obtained using Phy-X and XCOM program. The results obtained showed slight enhancement with increasing Ni contents. The substitution of Ni leads to progressive enhancement in effective removal cross-section of fast neutron ($Σ$R) values. Whereas the values of Mass Stopping Power (MSP) and projected range for the protons showed a gradual reduction with increasing Ni concentration. These findings suggest that the current ceramic samples can be useful as radiation shielding materials.

description: This paper applies production theory to define a new set of inputs for U.S. households for the post-war II period, tests the new inputs to see if they support a complete household-demand system, and reports a new social cost-of-living index. The data support a demand system with nine major input categories and yield plausible price, income, and translating-variable effects. Women's and men's housework are complements, but other input categories are substitutes for women's housework. Some changes in the demand are associated with household technology and demographics. My social cost-of-living index rises at an approximately 1.4 percent per year slower over the post-war era than the implicit price deflator.

description: Variation in income tax policies and health insurance costs are shown to be theoretically appropriate instruments to identify endogenous firm wage and benefit offers in a labor supply model. Empirical results show that firms are more likely to provide health insurance benefits in states with high marginal income tax rates and low hospitalization costs. The model implies that over the 1983-1995 period, large increases in health insurance costs and reductions in marginal income tax rates lowered the probability of receiving health insurance benefits from employers by 10 percentage points. This decrease in benefits lowered hours of labor supply by 4-7%.

description: In most environments, information is critical to consumers' decision making. Consumers have prior beliefs about quality and price of goods and services and obtain new information which is used to update these prior beliefs or to form posterior beliefs, i.e., Bayesian learning. New food products made from herbicide-tolerant and insect-resistant crops using bioengineering, have appeared in U.S. supermarkets starting in 1996. The objective of this paper is to examine in depth the role of consumerï¿½s prior beliefs about genetic modification and of diverse, new information on their willingness to pay for foods that might be genetically modified. One hypothesis is that prior beliefs matter and, second, consumers give less weight to information from interested than disinterested par ties. We use a unique data set collected from a set of economics experiments to show that consumers who had informed prior beliefs behaved as if they placed more trust in the third-party information than in information from interested parties. Participants whose prior beliefs were uninformed revealed greater variation in their bidding behavior than informed participants.

description: We employ optical spectroscopy from the Multi Unit Spectroscopic Explorer (MUSE) combined with X-ray and radio data to study the highly-ionized gas (HIG) phase of the feedback in a sample of five local nearby Active Galactic Nuclei (AGN). Thanks to the superb field of view and sensitivity of MUSE, we found that the HIG, traced by the coronal line [FeVII] $λ$6089, extends to scales not seen before, from 700 pc in Circinus and up to ~2 kpc in NGC5728 and NGC3393. The gas morphology is complex, following closely the radio jet and the X-ray emission. Emission line ratios suggest gas excitation by shocks produced by the passage of the radio jet. This scenario is further supported by the physical conditions derived for the HIG, stressing the importance of the mechanical feedback in AGN with low-power radio jets.

Mechanistic studies on human pancreatic [alpha]-amylase
Creators: name: Rydberg, Edwin Harold
Publisher: name: University of British Columbia
Year: 2009

description: Human pancreatic α-amylase (HPA) is known to hydrolyze maltooligosaccharides with retention of anomeric configuration utilizing at least two active site carboxylic acids as nucleophile and acid/base catalyst in a double displacement reaction. The roles of three conserved active site carboxylic acids (D197, E233, and D300) in the catalytic mechanism of HPA were studied by utilizing site-directed mutagenesis in combination with structural and kinetic analyses of the recombinant enzymes. All three residues were altered to both alanine and the corresponding amide, in addition several other variants were generated (E233A/D300A, E233K, D300H, D300Y). The ten mutants, and the wild-type HPA, were successfully expressed in Pichia pastoris, and were secreted at modest levels (10 mg/L). Isolation of the mutant proteins required development of a new purification strategy since the affinity precipitation used to purify wild-type HPA was demonstrated to be ineffective on the low activity ocamylases. Hydrophobic interaction chromatography followed by anion exchange chromatography provided the desired mutant enzymes in highly purified form. In addition, the recombinant enzymes were shown, by electrospray ionization mass spectrometry (ESI-MS) in combination with endoglycosidase F treatment, to be heterogeneously glycosylated at a single asparagine (N461). Partial deglycosylation of the recombinant enzymes allowed for their successful crystallization and subsequent structural characterization to 1.8 Å resolution. Kinetic analyses were performed on the mutants, utilizing a range of substrates. All results suggested that D197 was the nucleophile, since virtually all activity (>10 ⁵ fold decrease in k[sub cat] at values) was lost for the enzymes mutated at this position when assayed with each substrate. The significantly greater second order rate constant of E233 mutants on "activated" substrates (k[sub cat /K[sub m] value for α-maltotriosyl fluoride = 15 s⁻¹mM⁻¹) compared with "unactivated" substrates (k[sub cat /K[sub m] value for maltopentaose = 0.0030 s⁻¹ mM⁻¹) strongly suggested that E233 is the general acid catalyst. Data for the D300 mutants will be presented, although the role of D300 remains unclear. In conclusion, structural and kinetic analyses of wild-type and mutant HP As have provided strong evidence for the roles of two conserved active site carboxylic acids (D197 and E233) in its double displacement mechanism, while the role of D300 remains elusive.

description: Genetically modified organisms (GMO) crops have become increasingly popular with Iowa farmers over the past few years. The current genetic modifications are focused on pest management technologies. Although there were early efforts by environmental activists to disrupt the adoption of GMO technology, few concerns were raised by U.S. food retailers and consumers. The primary concern was getting European Union (EU) regulatory approval for each GMO crop variety event as late as spring 1999. The situation has changed dramatically in the last few months, and the current situation is highly uncertain. This paper provides the economic perspective on the issues surrounding non-GMO/GMO market segregation, the potential price impacts that may materialize with 1999 corn and soybeans, potential benefits from segregating, and issues in certifying non-GMO crops. This information should be useful as producers make decisions about marketing their 1999 crop.

description: The share of resources allocated to food marketed through supermarkets and their marketing channels has grown at an unprecedented rate in lower income countries during the 1990s. The implication is that the evolution of supermarkets cannot be viewed in isolation of the broader economic general equilibrium forces giving rise to a middle class, nor can this process be viewed in a static context. Our dynamic model captures, in an obviously aggregative way, the marketing channels that require resources to: assemble inputs for farmers, produce raw agricultural output, assemble, process and add value to, and market the final products to retail establishments in the long run.

description: Simulation-optimization techniques are employed to analyze changes in farmland control arrangements as a result of using different constructs of intertemporal risk behavior. Risk behavior based on constant absolute risk aversion (CARA) and constant relative risk aversion (CRRA) mean-standard deviation functions are used to achieve this objective. Specfically, a multi-period programming framework for a representative grain farm is developed to explore farmland control decisions under these two behavioral assumptions. Our results suggest that the use of a CRRA behavioral construct in analyzing farmland control decisions produce predictions that are more consistent with observed farm behavior.

description: Based on the first-order action for scalar-tensor theories with the Immirzi parameter, the symplectic form for the spacetimes admitting a weakly isolated horizon as internal boundary is derived by the covariant phase space approach. The first law of thermodynamics for the weakly isolated horizons with rotational symmetry is obtained. It turns out that the Immirzi parameter appears in the expression of the angular momentum of isolated horizon, and the scalar field contributes to the horizon entropy.

description: Estimating depth from RGB images is a long-standing ill-posed problem, which has been explored for decades by the computer vision, graphics, and machine learning communities. Among the existing techniques, stereo matching remains one of the most widely used in the literature due to its strong connection to the human binocular system. Traditionally, stereo-based depth estimation has been addressed through matching hand-crafted features across multiple images. Despite the extensive amount of research, these traditional techniques still suffer in the presence of highly textured areas, large uniform regions, and occlusions. Motivated by their growing success in solving various 2D and 3D vision problems, deep learning for stereo-based depth estimation has attracted growing interest from the community, with more than 150 papers published in this area between 2014 and 2019. This new generation of methods has demonstrated a significant leap in performance, enabling applications such as autonomous driving and augmented reality. In this article, we provide a comprehensive survey of this new and continuously growing field of research, summarize the most commonly used pipelines, and discuss their benefits and limitations. In retrospect of what has been achieved so far, we also conjecture what the future may hold for deep learning-based stereo for depth estimation research.

Year: 2005
Subjects: Farm Management

description: Empirical evidence for the existence of moral hazard in the U.S. crop insurance program has been inconclusive. Here we use a nested-dynamic programming framework to estimate an intra-seasonal dynamic model that explicitly incorporates a farmer's crop abandonment decision. The estimation is implemented for selected Texas counties where actuarial performances of the crop insurance program are poor and high incidences of acreage abandonment are frequently observed.

description: The paper studies the impacts of livestock facilities on property values, and extends the hedonic housing price models by explicitly modeling the way odor is dispersed in the atmosphere. Using a Gaussian dispersion model of odor, our estimation allows us to separately estimate the environmental effects and other effects, and to evaluate the marginal contributions of livestock facilities depending on their location.
17. Solar siblings

Publisher: name: Zenodo
Year: 2021

description: There are hints that our Sun was born in a star cluster, of perhaps a thousand other stars.  But was it, instead, born in isolation? If it was part of a larger cluster, where are the other members now?  Gaia is advancing the search for solar siblings, which also aims to gain a better understanding of the conditions under which life developed on Earth.

description: The Arkansas River in Colorado has a major salinity problem, due to agricultural runoff caused by irrigation. It is necessary to see how on-farm net sales, regional and state employment and income levels are affected by alternative aquifer recharge rates. The positive impacts were greatest for the 40% recharge rate.

description: A combined density and first-order reduced-density-matrix (1RDM) functional method is proposed for the calculation of potential energy curves (PECs) of molecular multibond dissociation. Its 1RDM functional part, a pair density functional, efficiently approximates the ab initio pair density of the complete active space self-consistent-field (CASSCF) method. The corresponding approximate on top pair density Π is employed to correct for double counting a correlation functional of density functional theory (DFT). The proposed ELS-DMΠDFT method with the extended Löwdin-Shull (ELS) 1RDM functional with dispersion and multibond (DM) corrections augmented with the ΠDFT functional closely reproduces PECs of multibond dissociation in the paradigmatic N_2 , H_2O, and H_2CO molecules calculated with the recently proposed CASΠDFT (CASSCF augmented with a Π based scaled DFT correlation correction) method. Furthermore, with the additional M-correction, ELS-DMΠDFT+M reproduces well the benchmark PEC of the N_2 molecule by Lie and Clementi.
CAPPA: Continuous-time Accelerated Proximal Point Algorithm for Sparse Recovery

description: This paper develops a novel Continuous-time Accelerated Proximal Point Algorithm (CAPPA) for $\ell_1$-minimization problems with provable fixed-time convergence guarantees. The problem of $\ell_1$-minimization appears in several contexts, such as sparse recovery (SR) in Compressed Sensing (CS) theory, and sparse linear and logistic regressions in machine learning to name a few. Most existing algorithms for solving $\ell_1$-minimization problems are discrete-time, inefficient and require exhaustive computer-guided iterations. CAPPA alleviates this problem on two fronts: (a) it encompasses a continuous-time algorithm that can be implemented using analog circuits; (b) it betters LCA and finite-time LCA (recently developed continuous-time dynamical systems for solving SR problems) by exhibiting provable fixed-time convergence to optimal solution. Consequently, CAPPA is better suited for fast and efficient handling of SR problems. Simulation studies are presented that corroborate computational advantages of CAPPA.

description: We analyze the movement of farm prices relative to other commodity prices in the period 1913:1-2003:12, investigating the number and time of structural breaks and discussing likely causes of structural breaks in the relative farm prices. Bai and Perron's (1998, 2003) multiple structural change test with a dynamic programming algorithm is used. This test makes it possible to have an efficient computation of the estimates of the break points as global minimizers of the sum of squared residuals. We find 6 structural breaks when we consider only the mean process and 2 breaks when we consider the mean and autoregressive processes. Possible causes for these breaks are discussed.

description: We present deep optical spectra of the archetypal young planetary nebula (PN) NGC 7027, covering a wavelength range from 3310 to 9160 A. The observations were carried out by uniformly scanning a long slit across the entire nebular surface, thus yielding average optical spectra for the whole nebula. A total of 937 emission features are detected. The extensive line list presented here should prove valuable for future spectroscopic analyses of emission line nebulae. The optical data, together with the archival IUE and ISO spectra, are used to probe the temperature and density structures and to determine the elemental abundances from lines produced by different excitation mechanisms. The C++/H+, N++/H+, O++/H+ and Ne++/H+ ionic abundance ratios derived from optical recombination lines (ORLs) are found to be only slightly higher than those derived from collisionally excited lines (CELs). We conclude that whatever mechanism is causing the BJ/CEL temperature discrepanies and the ORL/CEL abundance discrepancies that have been observed in many PNe, it has an insignificant effect on this bright young compact PN. The properties of the central star are also discussed. Based on the integrated spectrum and using the energy-balance method, we have derived an effective temperature of 219 000 K for the ionizing star. Finally, we report the first detection in the spectrum of this bright young PN of Raman-scattered O VI features at 6830 and 7088 A, pointing to the existence of abundant neutral hydrogen around the ionized regions.

description: The concept of sector coupling promises to provide flexibility for rising renewable shares. A strong metric is needed to determine the viability and economic feasibility of different sector coupled energy systems. A direct translation of key performance indicators (KPI) commonly used for single vector systems is not always possible. The KPI proposed have been developed based on a stakeholder workshop within the H2020 research project E Land.

description: It is often suggested that the poor are credit-rationed due to their lack of formal collateral. Using a household survey from Indonesia, we estimate the impact of having a land title on formal credit access. Adopting an instrumental variable approach, we find that having a formal title significantly increases a household's probability of ever having had a formal loan and the observed loan amount. Why land titles increase access to credit is still not clear. Incorporating data from a unique survey of bankers in Indonesia, we will argue that possessing a formal title increases a household's incidences of formal credit not because the value of the title as collateral but because of what possessing a title signals about the household to the banker. We apply a simple model of contract choice to show how title can act as an indirect signal.

description: In this paper we derive a joint continuous/censored demand system suitable for the analysis of commodity demand relationships using panel data. Unobserved heterogeneity is controlled for using a correlated random effects specification and a Generalized Method of Moments framework used to estimate the model in two stages. While relatively small differences in elasticity estimates are found between a flexible specification and one that restricts the relationship between the random effect and budget shares to be time invariant, larger differences are observed between the most flexible random effects model and a pooled cross sectional estimator. The results suggest the limited ability of such estimators to control for preference heterogeneity and unit value endogeneity leads to parameter bias.
Explicit height bounds for $K$-rational points on transverse curves in powers of elliptic curves

description: Let $C$ be an algebraic curve embedded transversally in a power $E^N$ of an elliptic curve $E$. In this article we produce a good explicit bound for the height of all the algebraic points on $C$ contained in the union of all proper algebraic subgroups of $E^N$. The method gives a totally explicit version of the Manin-Dam'janenko Theorem in the elliptic case and it is a generalisation of previous results only proved when $E$ does not have Complex Multiplication.

description: This article considers a long-outstanding open question regarding the Jacobian determinant for the relativistic Boltzmann equation in the center-of-momentum coordinates. For the Newtonian Boltzmann equation, the center-of-momentum coordinates have played a large role in the study of the Newtonian non-cutoff Boltzmann equation, in particular, we mention the widely used cancellation lemma by Alexandre et al. (Arch. Ration. Mech. Anal. 152(4):327-355, 2000). In this article we calculate specifically the very complicated Jacobian determinant, in ten variables, for the relativistic collision map from the momentum $p$ to the post-collisional momentum $p'$; specifically we calculate the determinant for $p\mapsto u = θp'+\left(1-θ\right)p$ for $θ\in [0,1]$. Afterwards we give an upper-bound for this determinant that has no singularity in both $p$ and $q$ variables. Next we give an example where we prove that the Jacobian goes to zero in a specific pointwise limit. We further explain the results of our numerical study which shows that the Jacobian determinant has a very large number of distinct points at which it is machine zero. This generalizes the work of Glassey-Strauss (Transport Theory Statist. Phys. 20(1):55-68, 1991) and Guo-Strain (Comm. Math. Phys. 310(3):649-673, 2012). These conclusions make it difficult to envision a direct relativistic analog of the Newtonian cancellation lemma in the center-of-momentum coordinates.
