description: The inventory system under consideration consists of one central warehouse and an arbitrary number of retailers controlled by a continuous review inventory policy (R,Q). Independent Poisson demands are assumed with constant transportation times for all retailers and a constant lead time for replenishing orders from an external supplier for the warehouse. Unsatisfied demands are assumed to be lost in the retailers and unsatisfied retailer orders are backordered in the warehouse. An approximate cost function is developed to find optimal reorder points for given batch sizes in all installations and the related accuracy is assessed through simulation.

description: The United States is the world’s leading importer and second-largest producer of avocados. U.S. per capita consumption increased from 0.69 kg in 1998 to 1.48 kg in 2007. The factors responsible include aggressive promotion of the health benefits, increased disposable income, and a rapidly growing Hispanic population. Such factors enabled the prices of avocados to remain fairly attractive over the period. However, with the recent downturn in the U.S. economy and prospects of further increases in supplies of avocados, there are concerns that prices could fall substantially. With the aid of multiple-regression analysis, this paper forecasts avocado prices up to the year 2012.
Direct Urca neutrino radiation from superfluid baryonic matter

description: Dense matter in compact stars cools efficiently by neutrino emission via the direct Urca processes n -> p + e + nu and p + e -> n + nu. Below the pairing phase transition temperature Tc these processes are suppressed - at asymptotically low temperatures exponentially. We compute the emissivity of the Urca process at one loop for temperatures T < Tc, in the case where the baryons are paired in the 1S0 partial wave. The Urca process is suppressed linearly, rather than exponentially, within the temperature range 0.1 < T/Tc < 1. The charge-current Cooper pair-breaking process contributes up to 50% of the total Urca emissivity in this temperature range.

description: Psyllobora bisoctonotata (Mulsant)
(Figs 183–185)
Vibidia bisoctonotata Mulsant, 1850: 204 (Type locality: Arabia).
Thea bisoctonotata: Crotch 1874: 134; Korschefsky 1932: 559.
Psyllobora bisoctonotata: Iablokoff-Khnzorian 1982: 301; Poorani 2002a: 342.
Diagnosis. Length: 3.20–3.50 mm; width: 2.20–2.50 mm. Form small, elongate oval and narrow, dorsum convex and glabrous. Ground colour pale creamy yellow; pronotum with a pale brown, indistinct, roughly M-shaped marking; elytra with 18 black spots, arranged in a 2-3-3-1 pattern (Fig. 184a), spots variable in size; lateral margins of pronotum and elytra transparent. Ventral side pale yellowish brown. Abdominal postcoxal line (Fig. 184b) very short and incomplete. Male genitalia (Fig. 184c–e) and spermatheca (Fig. 184f) as illustrated.
Immature stages. Eggs (Fig. 185a) whitish. Larva (Fig. 185b) and pupa (Fig. 185c, d) dull slaty grey, with yellow, black and white markings on dorsal side.
Distribution. India: Very common in northern India (Delhi, Gujarat, Haryana, Himachal Pradesh, Karnataka, Punjab, Tamil Nadu, Uttarakhand, Uttar Pradesh); Pakistan; Middle East; Egypt; Ethiopia; Uganda; Cape Verde. In India, it seems to have expanded its range to the colder parts of western and peninsular India in recent years and is rare in South India (except parts of Karnataka).
Prey/associated habitat. Feeds on mildews affecting Dalbergia sissoo, Bauhinia purpurea, sunflower, mulberry, Clerodendron sp., etc. (label data). Mass assemblages on Bauhinia purpurea sighted in winter in northwestern India (Kapur 1943). Beeson (1941) reported it as feeding on the epidermis of leaves of D. sissoo. In Bangalore, it is commonly collected on Dalbergia sissoo during the winter season (December–February, label data). Omkar & Pervez (1999) erroneously reported it as a predator of aphids and mealybugs in Uttar Pradesh.
Patankar et al. (2009) studied the gut contents and faecal pellets of Psyllobora bisoctonotata and I. cincta and found the spores of powdery mildew fungi (Phyllactinia dalbergiae and P. corylea) besides those of other plant pathogenic fungi such as Cladosporium spp., Alternaria spp., and Curvularia spp.
Seasonal occurrence. Collected in large numbers on D. sissoo almost throughout the year in and around Bangalore; particularly active in post-rainy season, feeding on mildew covered leaves. More common in summer than in autumn in northern India (Kapur, 1943).
Natural enemy. Nothoserphus mirabilis Brues (Hymenoptera: Proctotrupidae) (unpublished data).
Notes. Kapur (1943) and Kumar et al. (2010) studied its biology and described and illustrated the immature stages.

description: Uniform auctions are commonly used to elicit willingness to pay for new or novel products, product attributes, or non-market goods. However, most auctions or other contingent-valuation techniques do not allow for negative values, despite the fact that many consumers hold negative values for these products or product attributes. We conducted a WTP auction for a new product along with a within-sample WTA second auction allowing for negative responses. We find that failing to allow for negative values significantly inflates willingness to pay estimates and estimates of expected market share. This paper provides a method of incorporating negative values into auctions and willingness to pay elicitation.

The genetics of selective breeding in western hemlock Tsuga heterophylla
Creators: name: Wellman, Hugh Francis
Publisher: name: University of British Columbia
Year: 2009

description: Rates of genetic diversity were inferred from allozyme allelic variation and used to compare differing seed crops that had originated from seed orchards under various seed production conditions with natural stands of western hemlock (Tsuga heterophylla (Raf.) Sarg). The supplemental mass pollination (SMP) technique was found to maximize both Ht and H0 when compared with unimproved wind pollinated seed crops and controlled full-sib crosses. This was identified as being the result of minimized self-fertilization and an improved parental balance. It also can be noted that 8 private alleles were lost in the seed orchard populations when compared with natural populations. Results of an inbreeding analysis have suggested that when compared with natural populations, inbreeding decreased in the wind pollinated unimproved and controlled fullsib seed crops of first generation seed orchard. The SMP treatment also showed lower values of inbreeding and when compared with controlled crosses had the highest genetic diversity. These finding suggest that the SMP technique best maintains genetic diversity and minimizes inbreeding while retaining the required selection intensity for genetic gains. Fifteen microsatellite markers were isolated from western hemlock genomic DNA and six of these markers were optimized for use in mountain hemlock [Tsuga mertensiana (Bong) Carr.]. The developed SSR's were then implemented in a test of the Heterozygosity-Fitness Correlation (HFC) in western hemlock elite families. In general no significant relationship was identified between the genetic distance/relatedness of top western hemlock families and the fitness of their progeny based on phenotypic indicators. One exception were the MKL and STV progeny trials which were found to be significantly correlated at 9 5 % . They both showed negative slope indicating that as genetic distance increase, height decreases which is indicative of outbreeding depression. Reasons that may have lent to the null result include limited parental lines, concluding in too little distance variation, a low degree of relatedness resulting in very little inbreeding depression and very little evidence for linkage disequilibrium, a cause of associative overdominance. The lack of structure identified in Western hemlock populations may not have allowed for strong heterosis therefore resulting in the poor predictive power of genetic distance.

This may constitute a dark radiation component which can sufficiently alter the early cosmological evolution to alleviate the Hubble tension.

description: We show how the central equality of scattering theory, the definition of the $\mathbb{T}$ operator, can be used to generate hierarchies of mean-field constraints that act as natural complements to the standard electromagnetic design problem of optimizing some objective with respect to structural degrees of freedom. Proof-of-concept application to the problem of maximizing radiative Purcell enhancement for a dipolar current source in the vicinity of a structured medium, an effect central to many sensing and quantum technologies, yields performance bounds that are frequently more than an order of magnitude tighter than all current frameworks, highlighting the irreality of these models in the presence of differing domain and field-localization length scales. Closely related to domain decomposition and multi-grid methods, similar constructions are possible in any branch of wave physics, paving the way for systematic evaluations of fundamental limits beyond electromagnetism.

Risk and Uncertainty

description: The dichotomy between perceptions of the acceptability of risk associated with genetically modified (GM) foods and willingness to consume GM foods is investigated. Results indicate that some consumers are willing to consume GM foods even though they may perceive such foods as somewhat unsafe, with determinants such as self-perceived knowledge about the availability of GM foods and altruistic motives having positive and significant effects on their consumption decisions. Efforts toward decreasing perception of risk and ultimately increasing acceptance of and demand for GM foods should address issues related to their altruistic characteristics and outrage.

description: L’un de facteur important de morbidité et de mortalités maternelles c’est l’hémorragie du post-partum qui s’observe même dans les pays développés. Entre 2003 et 2010, l’incidence de l’HPP au Canada était de 5,6 cas par 100 accouchements. Les données internationales provenant de pays riches en ressources semblent indiquer que le taux s’approche plutôt de 10 % lorsque la perte sanguine est réellement mesurée et que ce taux continue d’augmenter, l’atonie utérine en étant la principale cause (1).

La mort maternelle par hémorragie est en diminution : depuis 15 ans le nombre de décès a été divisé par deux. C’est la preuve de l’amélioration des prises en charge grâce à la mobilisation collective. Le nombre de décès de ce triennium s’élève à 22, soit 8,4 % des morts maternelles et un ratio de mortalité maternelle par hémorragie de 1,0/100 000 naissances vivantes. Il existe néanmoins une proportion préoccupante de décès par hémorragie occulte. Un défaut de surveillance dans les suites immédiates est le plus souvent associé (1).

Le manque de sang est à l’origine de 40% des cas de décès des femmes, liés aux complications hémorragiques lors de l’accouchement en République du Congo. La RDC est l’un des pays ayant le ratio de la mortalité maternelle parmi les plus élevées au monde. Pour avoir souscrit aux objectifs de développement durables, elle doit consentir d’ici à 2030, au moins six fois plus d’efforts dans la réduction du taux. Soit, passer de 473 sur 100.000 naissances vivantes à 70. Selon les données chiffrées contenues dans le Système national d’information sanitaire, en abrégé SNIS, pour l’année 2017, le pays a enregistré un total de 8449 décès maternels (soit 2.827 répertoriés dans les institutions hospitalières et 5.622 signalés dans la communauté) dont 350 pour la capitale Kinshasa. En 2018, 6.517 décès maternels (soit 2.701 au niveau des formations sanitaires et 3.816 dans la communauté) dont 362 à Kinshasa. En 2019, 11.856 (2.816 au niveau des formations sanitaires et 9.040 dans la communauté) dont 253 à Kinshasa (2).

Avec le devoir ci-haut, nous nous sommes engagés à former les professionnelles de santé sur la prise en charge de l’hémorragie du post-partum.

description: Super Resolution is the problem of recovering a high-resolution image from a single or multiple low-resolution images of the same scene. It is an ill-posed problem since high frequency visual details of the scene are completely lost in low-resolution images. To overcome this, many machine learning approaches have been proposed aiming at training a model to recover the lost details in the new scenes. Such approaches include the recent successful effort in utilizing deep learning techniques to solve super resolution problem. As proven, data itself plays a significant role in the machine learning process especially deep learning approaches which are data hungry. Therefore, to solve the problem, the process of gathering data and its formation could be equally as vital as the machine learning technique used. Herein, we are proposing a new data acquisition technique for gathering real image data set which could be used as an input for super resolution, noise cancellation and quality enhancement techniques. We use a beam-splitter to capture the same scene by a low resolution camera and a high resolution camera. Since we also release the raw images, this large-scale dataset could be used for other tasks such as ISP generation. Unlike current small-scale dataset used for these tasks, our proposed dataset includes 11,421 pairs of low-resolution high-resolution images of diverse scenes. To our knowledge this is the most complete dataset for super resolution, ISP and image quality enhancement. The benchmarking result shows how the new dataset can be successfully used to significantly improve the quality of real-world image super resolution.

description: A directed a cyclical graph (DAG) methodology was used to discover changes in price relationships among cull cow markets in the U.S. and Canada resulting from the trade ban initiated by the discovery of bovine spongiform encephalopathy (BSE, also called mad cow disease), in a Canadian cow in 2003. Comparison of the pre- and post-ban DAGs supports the hypothesis that large structural changes in the flow of cull cow market information has occurred with significant changes both within and between countries. The typical flow of information from south to north and east to west was disrupted.

Correlated metal, Mott insulator and Anderson insulator phases are identified. The metal--insulator transitions are found to be continuous. The interaction and disorder compete with each other stabilizing the metallic phase against occurring one of the insulators. The Mott and Anderson insulators are found to be continuously connected.

description: We investigate quantum interference effects with magnetic field (magnetofingerprints) in strongly disordered Au-nanobridges. The magnetofingerprints are unconventional because they are caused by the Zeeman effect, not by the Aharonov-Bohm effect. These spin-based magnetofingerprints are equivalent to the Ericson's fluctuations (the fluctuations in electron transmission probability with electron energy). We present a model based on the Landauer-Buttiker formalism that describes the data. We show that the dephasing time $τ_ϕ(E,T)$ of electrons at temperature $T$ and energy $E$ above the Fermi level can be obtained from the correlation magnetic field. In samples with localization length comparable to sample size, $h/τ_ϕ(E,T) \approx E$, for $E\gg k_B T$, which shows that the Fermi liquid description of electron transport breaks down at length scale comparable to the localization length.

description: The phenomenological dynamics of the QCD critical phenomena is revisited. Recently, Son and Stephanov claimed that the dynamical universality class of the QCD phase transition belongs to model H. In their discussion, they employed a time-dependent Ginzburg-Landau equation for the net baryon number density, which is a conserved quantity. We derive the Langevin equation for the net baryon number density, i.e., the Cahn-Hilliard equation. Furthermore, they discussed the mode coupling induced through the {\it irreversible} current. Here, we show the {\it reversible} coupling can play a dominant role for describing the QCD critical dynamics and that the dynamical universality class does not necessarily belong to model H.

description: Genus Singhikalia Kapur
Singhikalia Kapur, 1963a: 16.
Type species: Singhikalia ornata Kapur, 1963a: 17, by original designation.
Diagnosis. Form broad oval, dorsum convex and densely pubescent. General appearance with red and black coloration and dorsal pubescence suggestive of Epilachnini. Lateral antennal insertions much closer to the eyes. Mandibles apically bifid. Labial terminal palpomere about as broad as penultimate one. Mesoventrite anteriorly strongly emarginate medially. Elytral lateral margins without marginal bead. Middle and hind tibia without apical spurs. Hind margin of ventrite 5 in female sinuate and produced medially backwards. Tarsal claws appendiculate. Male genitalia with penis having more than one sclerite that are distinctly separated by a membrane. Infundibulum in the form of at least lightly sclerotized piece of bursa at origin of sperm duct.
Distribution. India, China, Pakistan.
Affinities. Singhikalia is most unusual in Coccinellini because it is the only genus of the Indian region with distinct dorsal pubescence and outwardly resembles members of the tribe Epilachnini. It probably mimics members of Epilachnini because “both are often found in the same series in museum collections, suggesting that they may co-occur in the same area and host plants” (Escalona et al. 2017). Only Subepilachna Bielawski, 1963b, a genus endemic to Papua New Guinea, is comparable to Singhikalia in the tribe Coccinellini in having dorsal pubescence and it was synonymized with Singhikalia by Jadwiszczak (1990). However, Ślipiński et al. (2020) recognized both as valid genera on the basis of “pronounced differences in the male and female terminalia and external morphology”.
Included species. Two species are known from the Indian subcontinent- Singhikalia ornata Kapur, the type species, and S. duodecimguttata Xiao (newly recorded from Pakistan here).

description: Monitoring and Evaluation of policies is intrinsically challenging and requires a very high level of technical capacity. Appropriate statistical indicators have to be selected and calculated to satisfy the needs of final users, linking the date to statistical demand. Appropriate classifications and definitions are also essential, while different data-sources and highly disaggregated estimations are needed; for instance, for small areas estimations and rural areas. Furthermore, Evaluation of a policy is a specific purpose, different from monitoring a project or long run economic analysis. The paper try to address the argument from a National Account prospective, rely on the assumption that this is an appropriate macro-economic framework for statistics and to base scientific studies.

description: Millisecond radio pulsars are neutron stars that have been spun-up by the transfer of angular momentum during the low-mass X-ray binary phase. The transition from an accretion-powered to a rotation-powered pulsar takes place on evolutionary timescales at the end of the accretion process, however it may also occur sporadically in systems undergoing transient X-ray activity. We have obtained the first optical spectrum of the low mass transient X-ray pulsar SAX J1808.4-3658 in quiescence. Similar to the black widow millisecond pulsar B1957+20, this X-ray pulsar shows a large optical modulation at the orbital period due to an irradiated companion star. Using the brightness of the companion star as a bolometer, we conclude that a very high irradiating luminosity, a factor of ~100 larger than directly observed, must be present in the system. This most likely derives from a rotation-powered neutron star that resumes activity during quiescence.

AGN-1 are by far the largest contributors to the soft X-ray samples. Their evolution is responsible for the break in the 0.5-2 keV source counts. Their soft X-ray luminosity function clearly changes shape as a function of redshift, confirming earlier reports of luminosity--dependent density evolution. The space density with redshift changes significantly for different luminosity classes, showing a strong positive evolution up to a certain redshift and then a flattening. The redshift, at which the evolution peaks, changes considerably with X-ray luminosity. The amount of density evolution also depends strongly on X-ray luminosity, more than a factor of 100 at high luminosities, but less than a factor of 10 for low luminosities. For the first time, a significant decline of the space density of X-ray selected AGN towards high redshift has been detected. No significant evolution of the X-ray to optical spectral index is found for AGN-1. The constraints from the AGN luminosity function and evolution in comparison with the mass function of black holes in local galaxies indicates, that the average supermassive black hole has built up its mass through efficient accretion and is likely rapidly spinning.

description: Artificial spin ices are frustrated spin systems that can be engineered, wherein fine tuning of geometry and topology has allowed the design and characterization of exotic emergent phenomena at the constituent level. Here we report a realization of spin ice in a lattice of superconducting qubits. Unlike conventional artificial spin ice, our system is disordered by both quantum and thermal fluctuations. The ground state is classically described by the ice rule, and we achieve control over a fragile degeneracy point leading to a Coulomb phase. The ability to pin individual spins allows us to demonstrate Gauss's law for emergent effective monopoles in two dimensions. The demonstrated qubit control lays the groundwork for potential future study of topologically protected artificial quantum spin liquids.

description: Evidence-based or evidence-aware policy approaches are used in many different sectors (health, education, etc.). These approaches are less common in agriculture but are gradually emerging. Analysis of debates surrounding this trend sheds light on the particular nature of the difficulties faced by public decision-makers who are willing to use available scientific knowledge. After examining certain misunderstandings which arise in the international debate over evidence-based policy approaches, this paper addresses two specific issues: (i) the problems of competing evidence for using knowledge in the design of public policies and (ii) the potential role of rationalization tools in a possible "depoliticisation" of public decision-making.

description: The nuclear polarization of $\mathrm{H}_2$ molecules formed by recombination of nuclear polarized H atoms on the surface of a storage cell initially coated with a silicon-based polymer has been measured by using the longitudinal double-spin asymmetry in deep-inelastic positron-proton scattering. The molecules are found to have a substantial nuclear polarization, which is evidence that initially polarized atoms retain their nuclear polarization when absorbed on this type of surface

description: When different technologies are present in an industry, assuming a homogeneous technology will lead to misleading implications about technical change and inefficient policy recommendations. In this paper a latent class modelling approach and flexible estimation of the production structure is used to distinguish different technologies for a representative sample of E.U. dairy producers, as an industry exhibiting significant structural changes and differences in production systems in the past decades. The model uses a transformation function to recognize multiple outputs; separate technological classes based on multiple characteristics, a flexible generalized linear functional form, a variety of inputs, and random effects to capture firm heterogeneity; and measures of first- and second-order elasticities to represent technical change and biases. We find that if multiple production frontiers are embodied in the data, different firms exhibit different output or input intensities and changes associated with different production systems that are veiled by overall (average) measures. In particular, we find that farms that are larger and more capital intensive experience greater productivity, technical progress and labor savings, and enjoy scale economies that have increased over time.
Localized post-transcriptional gene silencing of the very long chain fatty acid condensing enzyme, CER6, and analysis of transcript accumulation in the anthers of developing flower buds of Arabidopsis thaliana
Creators: name: Houlahan, Nora Kathleen
Publisher: name: University of British Columbia

description: In Arabidopsis thaliana, both the stem wax and the pollen lipids are generated from very long chain fatty acid (VLCFA) precursors. A mutation in the gene encoding CER6, a condensing enzyme involved in VLCFA synthesis, results in plants with alterations in both the stem wax and the pollen coat lipid profiles. Phenotypically these plants lack epicuticular wax crystals on their stems and are conditionally male sterile. When grown under conditions of low humidity, the pollen of cer6 plants does not hydrate on a receptive stigma, although hydration will occur under high humidity growth conditions. This conditional male sterility can be exploited for use in breeding systems. Pollination of cer6 plants as the female parent will ensure no self-pollinated contaminants and the line can be easily propagated for future use through growth in high humidity. Alterations in stem wax profile are, however, not desirable as they may negatively influence the fitness of the plant. To address this problem, an RNAi construct was designed to induce localized silencing of the CER6 gene in the tissues where the pollen coat is produced. Transgenic plants expressing this silencing construct displayed a wildtype stem wax load and exhibited conditional male sterility. Analysis of RNA extracted from flower buds of the TI generation showed a decrease in CER6 expression at stage 12 of floral development in plants that were phenotypically conditionally male sterile. Analysis of the subsequent T2 and T3 generations revealed a reversion to a wildtype fertile phenotype in all of the initially silenced lines. Examination of CER6 transcript levels confirmed that this fertility was correlated to wildtype levels of expression at stage 12 of floral development. This loss of silencing was not the result of an aberrant transgene transcript that was unable to initiate silencing, as no such transcript could be detected in any of the plants examined. Rather, methylation of the transgene promoter was observed, indicating the transcriptional silencing of transgene expression.
The CAP and the EU budget: Do the ex-ante data tell the true?

description: The aim of this paper is to suggest the adoption of an "evidence based" approach in the analysis of CAP expenditure. The debate on CAP expenditure is generally based on ex-ante images of the budget as presented in the Multiannual Financial Framework and, before each financial year, on the budget appropriations for commitments. But this differs significantly from the actual payments as recorded ex-post in the Financial Reports. These differences are mainly concentrated on structural policies (such as regional and rural development policy), while they do not exist, or are minimal, in the mere transfer policies (such as in Pillar 1 of the CAP). Based as it is on a partial and distorted image of the expenditure, the analysis and discussion on the CAP reform is distorted as well.

description: We derive strong observational limits on any possible large-scale spatial variation in the values of physical 'constants' whose space-time evolution is driven by a scalar field. The limits are imposed by the isotropy of the microwave background on large angular scales in theories which describe space and time variations in the fine structure constant, the electron-proton mass ratio, and the Newtonian gravitational constant, G. Large-scale spatial fluctuations in the fine structure constant are bounded by 2x10^-9 and 1.2x10^-8 in the BSBM and VSL theories respectively, fluctuations in the electron-proton mass ratio by 9x10^-5 in the BM theory and fluctuations in G by 3.6x10^-10 in Brans-Dicke theory. These derived bounds are significantly stronger than any obtainable by direct observations of astrophysical objects at the present time.

description: The transfer-matrix eigenvalues of the isotropic open Heisenberg quantum spin-1/2 chain with non-diagonal boundary magnetic fields are known to satisfy a TQ-equation with an inhomogeneous term. We derive here a discrete Wronskian-type formula relating a solution of this inhomogeneous TQ-equation to the corresponding solution of a dual inhomogeneous TQ-equation.
