description: We re-analyse the implications of the DAMA/NaI experiment for mirror matter-type dark matter, taking into account information from the energy dependence of the DAMA annual modulation signal. This is combined with the null results from the CDMS experiment, leading to fairly well defined allowed regions of parameter space. The allowed regions of parameter space will be probed in the near future by the DAMA/LIBRA, CDMS, and other experiments, which should either exclude or confirm this explanation of the DAMA/NaI annual modulation signal. In particular, we predict that the CDMS experiments should find a positive signal around the threshold recoil energy region, E_R < 15 keV in the near future.

description: This article arose from a series of three lectures given at the Banach Center, Warsaw, during period of 24 March to 13 April, 2003. Morse functions are useful tool in revealing the geometric formation of its domain manifolds $M$. They define the handle decompositions of $M$ from which the additive homologies $H_{\ast}(M)$ may be constructed. In these lectures two further questions were emphasized. (1) How to find a Morse function on a given manifold? (2) From Morse functions can one derive the multiplicative cohomology rather than the additive homology?

description: This study examines p-interdependence and quantifies q-substitutability between domestic catfish and different species of imported fish in the U.S. fish market. In doing so, this study uses cointegration analyses for p-interdependence and structural analyses for q-substitutability. Cointegration analysis identifies the long run price equilibria between U.S. domestic catfish and different species of imported fish. The structural analyses show a degree of q-substitutability.

description: In this paper, we propose an efficient approach to generate dynamic and versatile humanoid walking with non-constant center of mass (COM) height. We exploit the benefits of using reduced order models (ROMs) and stepping control to generate dynamic and versatile walking motion. Specifically, we apply the stepping controller based on the Hybrid Linear Inverted Pendulum Model (H-LIP) to perturb a periodic walking motion of a 3D actuated Spring Loaded Inverted Pendulum (3D-aSLIP), which yields versatile walking behaviors of the 3D-aSLIP, including various 3D periodic walking, fixed location tracking, and global trajectory tracking. The 3D-aSLIP walking is then embedded on the fully-actuated humanoid via the task space control on the COM dynamics and ground reaction forces. The proposed approach is realized on the robot model of Atlas in simulation, wherein versatile dynamic motions are generated.

Medicinal plants used by Berber and Arab peoples of Morocco : ethnopharmacology and phytochemistry
Creators: name: Mouhajir, Fatima
Publisher: name: University of British Columbia
Year: 2009

description: Medicinal plants were selected on the basis of their use by Berber and Arab people to treat infectious diseases caused by viruses and microbes, as determined in interviews with 55 healers and herbalists of all regions of Morocco. Plants used traditionally to treat colds, flu, coughs, wounds, cuts, rashes, diarrhea, and fever were studied. Rare and endemic plants (205 plants of 55 families) of potential medicinal value, not investigated before, were collected from mountains (Rif, High, Middle and Anti Atlas) and eastern and western Moroccan Sahara, in the summers of 1997-2000. Many in use are toxic at high doses; consequently dosage is extremely important and may influence whether a plant is an effective medicine or a poison. Methanolic extracts of 75 Moroccan plants were evaluated against three mammalian viruses: herpes simplex, Sindbis and polio, at non-cytotoxic concentrations. Five extracts were active against all three viruses, 16 against two, and 24 against one. Thirty-two extracts showed lightenhanced, and two, light-dependent, activities. These results indicate that some of these plants are potential medicines against viral infections. Several plant species were also analyzed for antimicrobial activities. They displayed different patterns: a broad spectrum, or selective activity, against fungi or bacteria or in light only. A chemical survey of fifty plant species was performed by Electron Spin Resonance spectroscopy that detected fingerprints of phenolics that may have medicinal significance. The analysis of Nigella sativa revealed the presence of a high content of thymohydroquinones that have potent antimicrobial properties and may explain the activity of Nigella, in light and dark, against both gram-positive and gram-negative bacteria. The black seeds are used in Moroccan traditional medicine for infectious pulmonary and cough diseases as well as for other ailments. The significance of this research lies in the discovery of novel and useful biological activities from plants, and as a scientific documentation of the value of Moroccan Berber and Arab ethnomedicine. The availability of a local pharmacopoeia supported by scientific data could be beneficial to large populations who do not have access to modern drugs.

description: We present a detailed study of vector meson photoproduction in ultraperipheral heavy ion collisions (UPCs). Using the dipole model, we develop a framework for the joint impact parameter and transverse momentum dependent cross sections. We compute the unpolarized cross section and $\cos 2ϕ$ azimuthal angular correlation for $ρ^0$ photoproduction with $ϕ$ defined as the angle between the $ρ^0$'s transverse momentum and its decay product pion meson's transverse momentum. Our result on unpolarized coherent differential cross section gives excellent description to the STAR experimental data. A first comparison between theoretical calculation and experimental measurement on the $\cos 2ϕ$ azimuthal asymmetry, which results from the linearly polarized photons, is performed and reasonable agreement is reached. We find out the characteristic diffractive patterns at both RHIC and LHC energies and predict the impact parameter dependent $\cos 2ϕ$ azimuthal asymmetries for $ρ^0$ photoproduction by considering UPCs and peripheral collisions. The future experimental measurements at RHIC and LHC relevant to our calculations will provide a tool to rigorously investigate the coherent and incoherent production of vector meson in UPCs, as well as to probe the nuclear structure in heavy ion collisions.

description: Direct and indirect effects of exchange rates on foreign and home prices may induce a change in terms of trade and volume of trade. In particular, the price effect in substitutability between foreign and home products and endogeneity of the foreign price provide evidence for the indirect impact of the exchange rate on home price. Furthermore, elasticity of substitution and degree of returns to scale influence the impact of the exchange rate on terms of trade and trade volume. In an empirical examination of the Korean beef market, this study found a decrease in terms of trade and an increase in volume of trade when the U.S. dollar depreciates, and an increase in terms of trade and a decrease in volume of trade when the U.S. dollar appreciates. However, the effect on terms of trade is greater than the effect on volume, implying that the foreign price elasticity of import demand is less than one.
Instabilities of Galactic Disks in the Presence of Star Formation
Creators: name: Nusser, Adi
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We discuss the stability of galactic disks in which the energy of interstellar clouds is gained in encounters with expanding supernova remnants and lost in inelastic collisions. Energy gain and loss processes introduce a phase difference between the pressure and density perturbations, making disks unstable on small scales for several recipes of star formation. This is in contrast to the standard stability analysis in which small scale perturbations are stabilized by pressure. In the limit of small scales the dispersion relation for the growth rate reduces to that of thermal instabilities in a fluid without gravity. If instabilities lead to star formation, then our results imply a secondary mode of star formation which operates on small scales and feeds on the existence of a primary mode on intermediate scales. This may be interpreted as a positive feedback. Further, the standard stability criterion on intermediate scales is significantly modified.

description: Blockchain has the potential to accelerate the deployment of emissions trading systems (ETS) worldwide and improve upon the efficiency of existing systems. In this paper, we present a model for a permissioned blockchain implementation based on the successful European Union (EU) ETS and discuss its potential advantages over existing technology. We propose an ETS model that is both backwards compatible and future-proof, characterised by interconnectedness, transparency, tamper-resistance and high liquidity. Further, we identify key challenges to implementation of a blockchain ETS, as well as areas of future work required to enable a fully-decentralised blockchain ETS.

description: According to FAO (2005) about 13 million hectares of the word’s forest are lost due to deforestation. Naoto (2006) found Africa to lead the list of countries with the highest rate of deforestation. This worrisome situation is further aggravated by the possible negative impacts of climate change due to an increase in the mean global temperature. Evidence supports that Africa is most likely to suffer the most the devastating impacts of natural calamities such as droughts and floods. This paper sought to evaluate the causes of deforestation in 27 Sub-Saharan African (SSA) countries. Our model uses annual data spanning from 1990 to 2004. Trade and urban population tend to be associated with a decline in deforestation. On the other hand, we found strong evidence of the existence of the environmental Kuznets curve with regards to deforestation in Sub-Saharan Africa. Finally, our results suggest that countries with a floating exchange rate regime have the highest rate of deforestation. Should future deforestation in SSA continue at the present pace, the associated costs to their already weakened economies may be substantial?

 A very characteristic species which has a broad distribution from Guatemala to Bolivia, at high altitudes. Because the female has a distinct frons, it has been readily identified as this species, despite some morphological variation. There may therefore be several similar species present in previous samples of S. unipunctatus. A new species in this complex is described below, primarily distinguished by elevated interstriae on the declivity, and much stouter body shape.

description: Using biodiesel fuel to reduce emissions from diesel engines is an area of increasing interest. Many environmental benefits associated with biodiesel are not traded in markets and their estimation requires economic valuation methods applied to non-market goods and services. This paper presents the results of a contingent valuation survey conducted in 2006 in two Ohio regions to estimate willingness to pay for air pollution reduction arising from using biodiesel fuel in diesel engines. The double bounded parametric formulation was used to estimate mean WTP ranging from $157 to $457. These results yield estimated aggregate benefits ranging from $123 to $429 million and can be used as a starting point for cost-benefit analysis.

description: Increase in demand for ethanol as a fuel additive has resulted in growth in ethanol production. Ethanol is produced from corn by either wet milling or dry grind processing. In wet milling, the corn kernel is fractionated into different components, resulting in several coproducts. Wet mill plants are capital intensive because of equipment requirements and typically are corporate owned. In dry grind processing, the corn kernel is not fractionated and only one coproduct, distillers dried grains with solubles (DDGS), is generated. Dry grind plants require less equipment and capital than wet mills. They typically are producer owned and add direct benefits to rural economies. Most of the increase in ethanol production during the past decade is attributed to growth in the dry grind industry. The marketing of coproducts provides income to offset processing costs. For dry grind plants, this is especially important, because only one coproduct is available. Several issues affect DDGS marketing. The increasing volume of DDGS accompanying ethanol production could reduce market value; high phosphorus content could limit use of DDGS, because of animal waste disposal issues. Technologies to remove germ and fiber from DDGS could produce a coproduct suitable for feeding to nonruminants; this would expand the markets for DDGS. Reducing phosphorus in DDGS would sustain markets for conventional DDGS. New technologies could contribute to long term stability of dry grind plants.
Nonlinear Function Inversion using k-vector

Year: 2020
Subjects: subject: Data Structures and Algorithms (cs.DS)
subject: FOS: Computer and information sciences

description: This work introduces a general numerical technique to invert one dimensional analytic or tabulated nonlinear functions in assigned ranges of interest. The proposed approach is based on an optimal version of the k-vector range searching, an ad-hoc modification devised for function inversion. The optimality consists of retrieving always the same number of data ($1,2,\dots$) for a specified searching range to initiate the root solver. This provides flexibility to adapt the technique to a variety of root solvers (e.g., bisection, Newton, etc.), using a specified number of starting points. The proposed method allows to build an inverse function toolbox for a set of specified nonlinear functions. In particular, the method is suitable when intensive inversions of the same function are required. The inversion is extremely fast (almost instantaneous), but it requires a one-time preprocessing effort.

description: Various Monte Carlo techniques are used to determine the complete phase diagrams of the square well model for the attractive ranges $λ= 1.15$ and $λ= 1.25$. The results for the latter case are in agreement with earlier Monte Carlo simulations for the fluid-fluid coexistence curve and yield new results for the liquidus-solidus lines. Our results for $λ= 1.15$ are new. We find that the fluid-fluid critical point is metastable for both cases, with the case $λ= 1.25$ being just below the threshold value for metastability. We compare our results with prior studies and with experimental results for the gamma-II crystallin.

Quantized conical waves in multimode optical fibers

Subjects: subject: Optics (physics.optics)

description: Multimode optical fibers has emerged as the platform that will bridge the gap between nonlinear optics in bulk media and in single-mode fibers. However, the understanding of the transition between these two research fields still remains incomplete despite numerous investigations of intermodal nonlinear phenomena and spatiotemporal coupling. Some of the striking phenomena observed in bulk media with ultrashort and ultra-intense pulses (i.e., conical emission, harmonic generation and light bullets) require a deeper insight to be possibly unveiled in multimode fibers. Here we generalize the concept of conical waves described in bulk media towards structured media, such as multimode optical fibers, in which only a discrete and finite number of modes can propagate. The modal distribution of optical fibers provides a quantization of conical emission (e.g., quantized X-waves) through phase-matched resonant radiations (i.e., dispersive waves) seeded by optical shocks or ultrashort wave structures during spatiotemporal compression stages. Such quantized dispersion- and diffraction-free waves are generated when a rather intense short pulse propagates nonlinearly in a multimode waveguide, whatever the dispersion regime and waveguide geometry. Future nonlinear experiments in commercially-available multimode fibers could reveal different forms of conical emission and an easy control of supercontinuum light bullets.

description: Ant colony optimization (ACO) algorithms have previously been used to compile single short scales of psychological constructs. In the present article, we showcase the versatility of the ACO to construct multiple parallel short scales that adhere to several competing and interacting criteria simultaneously. Based on an initial pool of 120 knowledge items, we assembled three 12-item tests that (a) adequately cover the construct at the domain level, (b) follow a unidimensional measurement model, (c) allow reliable and (d) precise measurement of factual knowledge, and (e) are gender-fair. Moreover, we aligned the test characteristic and test information functions of the three tests to establish the equivalence of the tests. We cross-validated the assembled short scales and investigated their association with the full scale and covariates that were not included in the optimization procedure. Finally, we discuss potential extensions to metaheuristic test assembly and the equivalence of parallel knowledge tests in general.

description: In the current era of Gaia and large, high signal to noise stellar spectroscopic surveys, there is an unmet need for a reliable library of fundamentally calibrated stellar effective temperatures based on accurate stellar diameters. Here we present a set of precision diameters and temperatures for a sample of 6 dwarf, 5 sub-giant, and 5 giant stars observed with the PIONIER beam combiner at the VLTI. Science targets were observed in at least two sequences with five unique calibration stars each for accurate visibility calibration and to reduce the impact of bad calibrators. We use the standard PIONIER data reduction pipeline, but bootstrap over interferograms, in addition to employing a Monte-Carlo approach to account for correlated errors by sampling stellar parameters, limb darkening coefficients, and fluxes, as well as predicted calibrator angular diameters. The resulting diameters were then combined with bolometric fluxes derived from broadband Hipparcos-Tycho photometry and MARCS model bolometric corrections, plus parallaxes from Gaia to produce effective temperatures, physical radii, and luminosities for each star observed. Our stars have mean angular diameter and temperatures uncertainties of 0.8% and 0.9% respectively, with our sample including diameters for 10 stars with no pre-existing interferometric measurements. The remaining stars are consistent with previous measurements, with the exception of a single star which we observe here with PIONIER at both higher resolution and greater sensitivity than was achieved in earlier work.

description: We present submillimeter (CSO 350um) and millimeter (SEST 1.2 mm, OVRO 3 mm) photometry for 125 solar-type stars from the FEPS Spitzer Legacy program that have masses between ~0.5 and 2.0 Msun and ages from 3 Myr to 3 Gyr. Continuum emission was detected toward four stars with a signal to noise ratio >= 3$: the classical T Tauri stars RX J1842.9-3532, RX J1852.3-3700, and PDS 66 with SEST, and the debris disk system HD 107146 with OVRO. RXJ1842.9-3532 and RXJ1852.3-3700 are located in projection nearby the R CrA molecular cloud with estimated ages of ~10 Myr, while PDS66 is a probable member of the 20 Myr old Lower Centaurus-Crux subgroup of the Sco-Cen OB association. The continuum emission toward these three sources is unresolved at the 24'' SEST resolution and likely originates from circumstellar accretion disks, each with estimated dust masses of ~5x10**-5 Msun. Analysis of the visibility data toward HD107146 (age 80-200 Myr) indicates that the 3 mm continuum emission is centered on the star within the astrometric uncertainties and resolved with a gaussian-fit FWHM size of (6.5'' +/- 1.4'') x (4.2''+/-1.3''), or 185 AUx120 AU. The results from our continuum survey are combined with published observations to quantify the evolution of dust mass with time by comparing the mass distributions for samples with different stellar ages. The frequency distribution of circumstellar dust masses around solar-type stars in the Taurus molecular cloud (age ~2 Myr) is distinguished from that around 3-10 Myr and 10-30 Myr old stars at a significance level of ~1,5sigma and 3sigma respectively. These results suggest a decrease in the mass of dust contained in small dust grains and/or changes in the grain properties by stellar ages of 10-30 Myr, consistent with previous conclusions.

description: Multi-storey buildings can be constructed using timber panels for slabs or walls, which are stable and self-supporting, by using CLT panels - Cross Laminated Timber. They consist of several layers of timber boards glued with structural adhesive and arranged orthogonally. The slabs of CLT when combined with a concrete layer on the upper surface have their structural performance optimized for flexural stiffness, structure dynamics, as well as the best efficiency in meeting the requirements of the construction system such as thermal, acoustic and the fire behavior. This work studies the connection between the concrete and the CLT by circular notches in the timber through numerical simulation of the pushout test in the ANSYS software and comparing it to the analytical values. For the mechanical properties of the CLT strength classes C20 and C30 according to EN 338 were used.
Expression patterns of nitrate transporter genes (AtNRT) in Arabidopsis thaliana
Creators: name: Okamoto, Mamoru
Publisher: name: University of British Columbia
Year: 2009

description: Higher plants possess both high- and low-affinity nitrate transporters. Since the first Arabidopsis thaliana low-affinity nitrate transporter gene, AtNRTl.l (CHL1), was isolated (Tsay et al., 1993), three low-affinity (NRT1), and seven high-affinity (NRT2) nitrate transporter gene homologues have been identified in this species. We investigated the transcript abundances of all eleven genes both in shoot and root tissues in response to NO3" provision, by relative quantitative RT-PCR method. Based upon their patterns of expression following NO3⁻ provision, the genes were classified into three groups: 1. nitrate-inducible, 2. nitrate-repressible, and 3. nitrate-constitutive. AtNRTl.l, 2.1, and 2.2, representatives of the first group, were strongly induced, by 1 mM NO₃ ⁻, peaking at 3 to 12 hours, and declining during 3 subsequent days. By contrast AtNRT2.4 showed only modest induction both in shoots and roots. Expression of AtNRT2.7, one of the nitrate-repressible genes from the second group, was strongly suppressed by nitrate provision in both roots and shoots. The last group, characterized by a constitutive expression pattern, contains the largest membership, including AtNRTl.2, 1.4, 2.3, 2.5, and 2.6. Tissue-specific expression patterns of limited number of AtNRT genes were observed by using GUS reporter DNA fusion lines. In the root tip regions, AtNRTl.l, 2.1 and 2.4 were expressed, while in the epidermal cells of mature roots, AtNRT2.1, 2.2, 2.4, and 2.6 were expressed. Expression of AtNRT2.1 was also found in the cortex and endodermal cells. In shoots AtNRTl.l showed expression in leaves and flowers, while AtNRT2.6 was specifically expressed in pollen grains. ¹³NO₃⁻ - influx from 100|iM and 5mM [NO₃⁻], chosen to examine high-affinity and low-affinity transport, respectively, corresponded closely with the expression patterns of AtNRT2.1 and 1,1 respectively. These results indicate that despite the close homology among members of the NRT2 and NRT1 families, individual members appear to be differently regulated, and may therefore perform different functions with respect to nitrate transport.
Rigidly rotating perfect fluid stars in $2+1$ dimensions

description: Cataldo has found all rigidly rotating self-gravitating perfect fluid solutions in 2+1 dimensions with a negative cosmological constant $Λ$, for a density that is specified a priori as a function of a certain radial coordinate. We rewrite these solutions in standard polar-radial coordinates, for an arbitrary barotropic equation of state $p(ρ)$. For any given equation of state, we find the two-parameter family of solutions with a regular centre and finite total mass $M$ and angular momentum $J$ (rigidly rotating stars). For analytic equations of state, the solution is analytic except at the surface, but including at the centre. Defining the dimensionless spin $\tilde J:=\sqrt{-Λ}\,J$, there is precisely one solution for each $(\tilde J,M)$ in the region $|\tilde J|-1|M|$. In an adjacent compact part of the black hole region $|\tilde J|

XMM-Newton Archival Study of the ULX Population in Nearby Galaxies

description: We present the results of an archival XMM-Newton study of the bright X-ray point sources (L_X > 10^38 erg/s) in 32 nearby galaxies. From our list of approximately 100 point sources, we attempt to determine if there is a low-state counterpart to the Ultraluminous X-ray (ULX) population, searching for a soft-hard state dichotomy similar to that known for Galactic X-ray binaries and testing the specific predictions of the IMBH hypothesis. To this end, we searched for "low-state" objects, which we defined as objects within our sample which had a spectrum well fit by a simple absorbed power law, and "high-state" objects, which we defined as objects better fit by a combined blackbody and a power law. Assuming that ``low-state'' objects accrete at approximately 10% of the Eddington luminosity (Done & Gierlinski 2003) and that "high-state" objects accrete near the Eddington luminosity we further divided our sample of sources into low and high state ULX sources. We classify 16 sources as low-state ULXs and 26 objects as high-state ULXs. As in Galactic black hole systems, the spectral indices, Gamma, of the low-state objects, as well as the luminosities, tend to be lower than those of the high-state objects. The observed range of blackbody temperatures for the high state is 0.1-1 keV, with the most luminous systems tending toward the lowest temperatures. We therefore divide our high-state ULXs into candidate IMBHs (with blackbody temperatures of approximately 0.1 keV) and candidate stellar mass BHs (with blackbody temperatures of approximately 1.0 keV). A subset of the candidate stellar mass BHs have spectra that are well-fit by a Comptonization model, a property similar of Galactic BHs radiating in the "very-high" state near the Eddington limit.

description: In this paper we report photovoltaic devices fabricated from PbS nanocrystals and the conducting polymer poly MEH-PPV. This composite material was produced via a new single-pot synthesis which solves many of the issues associated with existing methods. Our devices have white light power conversion efficiencies under AM1.5 illumination of 0.7% and single wavelength conversion efficiencies of 1.1%. Additionally, they exhibit remarkably good ideality factors (n=1.15). Our measurements show that these composites have significant potential as soft optoelectronic materials.

description: This paper uses plant-level micro-data from the 2002 Census of Manufactures, Food Safety Inspection Service, and the Economic Research Service in a translog cost function to examine the costs of effort devoted to the performance of sanitation and process control tasks and levels of food safety technology use. Results suggest that more effort devoted to performance of sanitation and process control tasks and greater use of food safety technologies modestly reduce long run costs.

description: Topological photonics harnesses the physics of topological insulators to control the behavior of light. Photonic modes robust against material imperfections are an example of such control. In this work, we propose a soft-matter platform based on nematic liquid crystals that supports photonic topological insulators. The orientation of liquid crystal molecules introduces an extra geometric degree of freedom which in conjunction with suitably designed structural properties, leads to the creation of topologically protected states of light. The use of soft building blocks potentially allows for reconfigurable systems that exploit the interplay between light and the soft responsive medium.

description: The Penna bit-string model successfully encompasses many phenomena of population evolution, including inheritance, mutation, evolution and ageing. If we consider social interactions among individuals in the Penna model, the population will form a complex network. In this paper, we first modify the Verhulst factor to control only the birth rate, and introduce activity-based preferential reproduction of offspring in the Penna model. The social interactions among individuals are generated by both inheritance and activity-based preferential increase. Then we study the properties of the complex network generated by the modified Penna model. We find that the resulting complex network has a small-world effect and the assortative mixing property.

description: We characterize the high-temperature thermodynamics of rotating bosons and fermions in two- (2D) and three-dimensional (3D) isotropic harmonic trapping potentials. We begin by calculating analytically the conventional virial coefficients $b_n$ for all $n$ in the noninteracting case, as functions of the trapping and rotational frequencies. We also report on the virial coefficients for the angular momentum and associated moment of inertia. Using the bn coefficients, we analyze the deconfined limit (in which the angular frequency matches the trapping frequency) and derive explicitly the limiting form of the partition function, showing from the thermodynamic standpoint how both the 2D and 3D cases become effectively homogeneous 2D systems. To tackle the virial coefficients in the presence of weak interactions, we implement a coarse temporal lattice approximation and obtain virial coefficients up to third order.
