Daedalma

description: Daedalma vertex Pyrcz
 Daedalma vertex Pyrcz, 2004: 511–512, 596 (Figs. 55, 56), 608 (Fig. 148).
 Remarks: This species currently comprises two subspecies found in central and northern Peru, on the eastern slopes of the Andes. It shares with D. dinias the character of the FWD orange patch never extending distally from the discal cell, but this is where the similarity between the two species ends. Daedalma vertex is considerably larger, the orange patch is more elongate, with somewhat irregular edges, and always indented at the base of vein Cu1. In most specimens D. vertex has a blackish postmedian spot enclosed by orange in cell Cu1-Cu2. The HWV pattern is also darker, more similar in this respect to D. fraudata and D. boliviana.

description: We examine a set of potentially climate smart agricultural practices, including reduced tillage, crop rotation and legume intercropping, combined with the use of improved seeds and inorganic fertiliser, for their effects on maize yields in Zambia. We use panel data from the Rural Incomes and Livelihoods Surveys merged with a novel set of climatic variables based on geo-referenced historical rainfall and temperature data to explore the changing effects of these practices with climatic conditions. We estimate the impacts on maize yields, and also on the exhibition of very low yields and yield shortfalls from average levels, as indicators of resilience, while controlling for household characteristics. We find that minimum soil disturbance and crop rotation have no significant impact on these yield outcomes, but that legume intercropping significantly increases yields and reduces the probability of low yields even under critical weather stress during the growing season. We also find that the average positive impacts of modern input use (seeds and fertilisers) are significantly conditioned by climatic variables. Timely access to fertiliser emerges as one of the most robust determinants of yields and their resilience. These results have policy implications for targeted interventions to improve theproductivity and the resilience of smallholder agriculture in Zambia in the face of climate change.

description: A Physical Unclonable Function (PUF) is a device with unique behaviour that is hard to clone hence providing a secure fingerprint. A variety of PUF structures and PUF-based applications have been explored theoretically as well as being implemented in practical settings. Recently, the inherent unclonability of quantum states has been exploited to derive the quantum analogue of PUF as well as new proposals for the implementation of PUF. We present the first comprehensive study of quantum Physical Unclonable Functions (qPUFs) with quantum cryptographic tools. We formally define qPUFs, encapsulating all requirements of classical PUFs as well as introducing a new testability feature inherent to the quantum setting only. We use a quantum game-based framework to define different levels of security for qPUFs: quantum exponential unforgeability, quantum existential unforgeability and quantum selective unforgeability. We introduce a new quantum attack technique based on the universal quantum emulator algorithm of Marvin and Lloyd to prove no qPUF can provide quantum existential unforgeability. On the other hand, we prove that a large family of qPUFs (called unitary PUFs) can provide quantum selective unforgeability which is the desired level of security for most PUF-based applications.

description: Many of the ‘new’ agricultural input subsidy programs (ISPs) in sub-Saharan Africa include among their objectives raising farm incomes and reducing rural poverty, but there is a dearth of empirical evidence on whether ISPs are achieving these objectives. Focusing on the case of Zambia, where ISPs account for approximately 50% of all agricultural sector poverty reduction program expenditures, we use nationally-representative panel survey data to estimate the effects of ISP fertilizer on smallholder farm household incomes, poverty incidence, and poverty severity based on the US$2 and US$1.25/capita/day poverty lines. Panel data (fixed effects and correlated random effects) and instrumental variables/control function methods are used to correct for the potential endogeneity of subsidized fertilizer to household incomes and poverty status. Results suggest that although ISP fertilizer raises incomes, the increase is not large enough or widely distributed enough to substantively reduce poverty incidence or severity among smallholder farm households in Zambia.

description: We present results from a Chandra X-ray Observatory study of the field X-ray source population in the vicinity of the radio galaxy MRC 1138-262. Many serendipitous X-ray sources are detected in an area of 8'x8' around the radio source and 90% are identified in our deep VLT images. The space density of such sources is higher than expected on the basis of the statistics of ROSAT and Chandra deep surveys. The most likely explanation is in terms of a concentration of AGN associated with the protocluster at z=2.16 which was found around the radio galaxy in previous studies. Two sources have a confirmed spectroscopic redshift close to that of the radio galaxy, and for three more sources other observations suggest that they are associated with the protocluster. Four of these five X-ray sources form, together with the radio galaxy, a filament in the plane of the sky. The direction of the filament is similar to that of the radio source axis, the large scale distribution of the other protocluster members, the 150 kpc-sized emission-line halo and the extended X-ray emission associated with the radio galaxy. The majority of optically identified X-ray sources in this field have properties consistent with type I AGN, a few could be soft, low luminosity galaxies, one is probably an obscured (type II) AGN and one is a star. These statistics are consistent with the results of deep X-ray surveys.

description: We study distributed algorithms for string matching problem in presence of wildcard characters. Given a string T (a text), we look for all occurrences of another string P (a pattern) as a substring of string T . Each wildcard character in the pattern matches a specific class of strings based on its type. String matching is one of the most fundamental problems in computer science, especially in the fields of bioinformatics and machine learning. Persistent effort has led to a variety of algorithms for the problem since 1960s. With rise of big data and the inevitable demand to solve problems on huge data sets, there have been many attempts to adapt classic algorithms into the MPC framework to obtain further efficiency. MPC is a recent framework for parallel computation of big data, which is designed to capture the MapReduce-like algorithms. In this paper, we study the string matching problem using a set of tools translated to MPC model. We consider three types of wildcards in string matching: - '?' wildcard: In this setting, the pattern is allowed to contain special '?' characters or don't cares that match any character of the text. String matching with don't cares could be solved by fast convolutions, and we give a constant round MPC algorithm for which by utilizing FFT in a constant number of MPC rounds. - '+' wildcard: '+' wildcard is a special character that allows for arbitrary repetitions of a character. When the pattern contains '+' wildcard characters, our algorithm runs in a constant number of MPC rounds by a reduction from subset matching problem. - '*' wildcard: '*' is a special character that matches with any substring of the text. When '*' is allowed in the pattern, we solve two special cases of the problem in logarithmic rounds.

description: We have collected from the literature a list of early-type stars, situated at large distances from the galactic plane, for which evidence of youth seems convincing. We discuss two possible formation mechanisms for these stars: ejection from the plane by dynamical interactions within small clusters, and formation away from the plane, via induced shocks created by spiral density waves. We identify the stars that could be explained by each mechanism. We conclude that the ejection mechanism can account for about two thirds of the stars, while a combination of star formation at z = 500-800 pc from the plane and ejection, can account for 90 percent of these stars. Neither mechanism, nor both together, can explain the most extreme examples.

description: Premium price is one of the most attractive features of organic farming but having access to one possess various difficulties, especially in the context of developing countries. The objective of this study is to analyze factors impacting involvement in marketing of crops and intensity of income generation therein between organic and conventional farmers by taking into consideration the existence of premium market. It was conducted in semi-urban Chitwan district of Nepal where group conversion to organic farming exists. Data from 285 respondents, selected using stratified sampling method, were analyzed using probit and ordinary least square model. This study finds that income from organic farming is less than conventional farming because production per hectare, commercialization rate and price at which the crops are sold per unit is higher for conventional farm, and access to premium market is very limited. This should be the primary focus for making organic farming monetarily attractive.

description: The vertebral skeleton is a defining feature of vertebrate animals. However, the mode of vertebral segmentation varies considerably between major lineages. In tetrapods, adjacent somite halves recombine to form a single vertebra through the process of ‘resegmentation’. In teleost fishes, there is considerable mixing between cells of the anterior and posterior somite halves, without clear resegmentation. To determine whether resegmentation is a tetrapod novelty, or an ancestral feature of jawed vertebrates, we tested the relationship between somites and vertebrae in a cartilaginous fish, the skate (Leucoraja erinacea). Using cell lineage tracing, we show that skate trunk vertebrae arise through tetrapod-like resegmentation, with anterior and posterior halves of each vertebra deriving from adjacent somites. We further show that tail vertebrae also arise through resegmentation, though with a duplication of the number of vertebrae per body segment. These findings resolve axial resegmentation as an ancestral feature of the jawed vertebrate body plan.

description: We develop the extended dynamical mean field theory (E-DMFT) with a view towards realistic applications. {\bf 1)} We introduce an intuitive derivation of the E-DMFT formalism. By identifying the Hartree contributions before the E-DMFT treatment, it allows to handle systems in symmetry breaking phases within a simple formalism. {\bf 2)} We make a new implementation of E-DMFT through real Hubbard-Stratonovich transformation to decouple the non-local two-particle interactions. We apply it to a 3D U-V model and investigate the behavior of the various Green's functions, especially the density susceptibility, as the density instability is approached. We obtain the phase diagram at a finite temperature. {\bf 3)} We present a formalism incorporating E-DMFT with Cellular DMFT. {\bf 4)} We suggest an improvement of the E-DMFT approach by combining it with a generalized GW method. The method combines the local self-energy from E-DMFT and the non-local ones from the perturbative calculation of GW. We apply the method to a 1D U-V model with two sublattices carrying different chemical potentials. By comparing with those from DMRG, we show the results are shifted in the correct direction due to the GW contributions. {\bf 5)} In order to handle the generic Coulomb repulsion within E-DMFT, we describe a method to tailor E-DMFT so that proper momentum dependence can be kept in general response functions.

description: Recent large-scale investments in agricultural land that are coupled with irrigation present opportunities for increased food production in sub-Saharan Africa. However, to achieve this objective two management issues must be addressed: efficient water use in the face of a looming water scarcity and equity in the sharing of the resource between large-scale investors and smallholder farmers. Focusing on the Office du Niger, one of the largest irrigable areas in Africa this paper compares the performance of three alternative water valuation methods: the currently used flat rate area-based pricing, uniform pricing and increasing block tariffs. Results show the limitations of the current pricing system in economic efficiency and equity terms and in terms of generating sufficient revenue to meet water supply costs. The paper shows that volumetric water pricing avoids these shortcomings and allows the water decision maker to weigh the efficiency-equity trade-offs in irrigation water management.

description: Nanowires are versatile nanostructures, which allow an exquisite control over bandgap energies and charge carrier dynamics making them highly attractive as building blocks for a broad range of photonic devices. For optimal solutions concerning device performance and cost, a crucial element is the selection of a suitable material system which could enable a large wavelength tunability, strong light interaction and simple integration with the mainstream silicon technologies. The emerging GaBiAs alloys offer such promising features and may lead to a new era of technologies. Here, we apply million-atom atomistic simulations to design GaBiAs/GaAs core-shell nanowires suitable for low-loss telecom-wavelength photonic devices. The effects of internal strain, Bi Composition (x), random alloy configuration, and core-to-shell diameter ratio ($\rm ρ_D$) are analysed and delineated by systematically varying these attributes and studying their impact on the absorption wavelength and charge carrier confinement. The complex interplay between x and $\rm ρ_D$ results in two distinct pathways to accomplish 1.55 um optical transitions: either fabricate nanowires with $\rm ρ_D \geq$ 0.8 and $x \sim$15\%, or increase $x$ to $\sim$30\% with $\rm ρ_D \leq$ 0.4. Upon further analysis of the electron hole wave functions, inhomogeneous broadening and optical transition strengths, the nanowires with $\rm ρ_D \leq$ 0.4 are unveiled to render favourable properties for the design of photonic devices. Another important outcome of our study is to demonstrate the possibility of modulating the strain character from a compressive to a tensile regime by simply engineering the thickness of the core region. The availability of such a straightforward knob for strain manipulation would be highly desirable for devices involving polarisation-sensitive light interactions.

description: The genetic contribution and economic impacts of exotic germplasm (particularly IRRI’s and Japan’s material) to China’s rice production are studied based on the analysis of varieties’ pedigree information from 16 major rice producing provinces in China during 1982-2011. The results indicated that the exotic germplasm, especially those coming from the International Rice Research Institute (IRRI) and Japan contributed greatly to China’s rice production and varietal improvement efforts. IRRI is the biggest contributors to China rice production, the average contribute rate reach 16.3% in 30 years. The contribution to china rice production increase gradually during the 1980s’, it reached its peak 23.59% in 1990 then declined gradually over the years that followed. The trend of Japanese varieties manifests a steady share since 1992. And their overall importance shows no sign of fading. The policy implication means that government should encourage breeders to focus more on the use and improvement of exotic germplasm.

description: I will present our recent results on the spectrum of a confining flux tube that is closed around a spatial torus as a function of its length. The extraction of the spectrum has been realized using lattice techniques. I will briefly demonstrate the spectrum in 2+1 and then I will focus on the case of 3+1 dimensional SU(N) gauge theories. For D=3+1 we have performed a calculation for N=3,5,6 and for various values of spin, parity and longitudinal momentum. A new extended basis of operators enables us to extract the first few excitation states for each different combination of spin and parity. Long flux-tubes can be thought of as infinitesimally thin strings; hence their spectrum is expected to be described by an effective string theory. Furthermore, the flux-tube's internal structure makes possible the existence of massive states in addition to string modes. Recent theoretical advances which made use of our old and less accurate results on D=3+1 provided evidence for the existence of a massive particle with particular (axionic) quantum numbers on the world-sheet of the QCD flux-tube. Our calculations on the spectrum of the flux tube in D=2+1 have shown that this is very well described by the Nambu-Goto bosonic string up to small deviations. However, our results in D=3+1 demonstrate that albeit most states exhibit spectrum which can be approximated adequately by Nambu-Goto there is now an even stronger evidence for the existence of a massive axion on the world-sheet of the QCD flux-tube as well as a bound state of two such axions twice as massive. Hence, a complete picture of the low-lying spectrum of the confining flux-tube will be provided

description: We investigate the non-BPS realm of 3d ${\cal N} = 4$ superconformal field theory by uniting the non-perturbative methods of the conformal bootstrap and supersymmetric localization, and utilizing special features of 3d ${\cal N} = 4$ theories such as mirror symmetry and a protected sector described by topological quantum mechanics (TQM). Supersymmetric localization allows for the exact determination of the conformal and flavor central charges, and the latter can be fed into the mini-bootstrap of the TQM to solve for a subset of the OPE data. We examine the implications of the $\mathbb{Z}_2$ mirror action for the SCFT single- and mixed-branch crossing equations for the moment map operators, and apply numerical bootstrap to obtain universal constraints on OPE data for given flavor symmetry groups. A key ingredient in applying the bootstrap analysis is the determination of the mixed-branch superconformal blocks. Among other results, we show that the simplest known self-mirror theory with $SU(2) \times SU(2)$ flavor symmetry saturates our bootstrap bounds, which allows us to extract the non-BPS data and examine the self-mirror $\mathbb{Z}_2$ symmetry thereof.

description: Menten, Reid, Eckart and Genzel (1997) accurately determined the position of Sgr A* on an infrared image, by aligning the infrared image with positions measured for SiO masers, associated with infrared-bright evolved stars, at radio wavelengths. We now report greatly improved radio positions and, for the first time, proper motions of many stellar SiO masers at the Galactic Center. These positions and motions, coupled with better infrared imaging, allow a much improved location of Sgr A* on infrared images. With current data, infrared stars can be placed in a reference frame tied to Sgr A*, to an accuracy of approximately 10 mas in position and 1 mas/yr in motion. The position of Sgr A* is, within uncertainties, consistent with stellar accelerations and the measured orbital focus of the star S2. The star S2 was observed within 16 mas (130 AU in projection) of Sgr A* on 2002 May 02. Finally, we find that the central stellar cluster moves with Sgr A* to within approximatly 70 km/s.

description: Automatic liver lesion segmentation is a challenging task while having a significant impact on assisting medical professionals in the designing of effective treatment and planning proper care. In this paper we propose a cascaded system that combines both 2D and 3D convolutional neural networks to effectively segment hepatic lesions. Our 2D network operates on a slice by slice basis to segment the liver and larger tumors, while we use a 3D network to detect small lesions that are often missed in a 2D segmentation design. We employ this algorithm on the LiTS challenge obtaining a Dice score per case of 68.1%, which performs the best among all non pre-trained models and the second best among published methods. We also perform two-fold cross-validation to reveal the over- and under-segmentation issues in the LiTS annotations.

description: This paper examines cointegration and the difference in the extent of price transmission, and speed of adjustment between global and domestic prices of high and low quality rice. Unit root tests, cointegration tests and error correction models are employed in the analysis. While there are no comparable studies in the literature, the findings of this study indicate that the dynamics of price transmission may be different between high and low quality rice markets. That is, the extent of price transmission appears to be larger for the global prices of low quality rice whereas the speed of adjustment to the long-run equilibrium may be faster for domestic prices of high quality rice. Moreover, a shock in the global prices of low quality rice may have a long-lasting effect on domestic prices of low quality rice as compared to their high quality counterparts affecting domestic prices of high quality rice.

description: The three-dimensional integer-valued lattice gauge theory, which is also known as a "frozen superconductor," can be obtained as a certain limit of the Ginzburg-Landau theory of superconductivity, and is believed to be in the same universality class. It is also exactly dual to the three-dimensional XY model. We use this duality to demonstrate the practicality of recently developed methods for studying topological defects, and investigate the critical behavior of the phase transition using numerical Monte Carlo simulations of both theories. On the gauge theory side, we concentrate on the vortex tension and the penetration depth, which map onto the correlation lengths of the order parameter and the Noether current in the XY model, respectively. We show how these quantities behave near the critical point, and that the penetration depth exhibits critical scaling only very close to the transition point. This may explain the failure of superconductor experiments to see the inverted XY model scaling.

Phase transitions in self-gravitating systems. Self-gravitating fermions and hard spheres models

description: We discuss the nature of phase transitions in self-gravitating systems both in the microcanonical and in the canonical ensemble. We avoid the divergence of the gravitational potential at short distances by considering the case of self-gravitating fermions and hard spheres models. Three kinds of phase transitions (of zeroth, first and second order) are evidenced. They separate a ``gaseous'' phase with a smoothly varying distribution of matter from a ``condensed'' phase with a core-halo structure. We propose a simple analytical model to describe these phase transitions. We determine the value of energy (in the microcanonical ensemble) and temperature (in the canonical ensemble) at the transition point and we study their dependance with the degeneracy parameter (for fermions) or with the size of the particles (for a hard spheres gas). Scaling laws are obtained analytically in the asymptotic limit of a small short distance cut-off. Our analytical model captures the essential physics of the problem and compares remarkably well with the full numerical solutions.

description: We derive the coordinate representation of the one-spinon one-holon wavefunction for the supersymmetric $t-J$ model with $1/r^2$-interaction. This result allows us to show that spinon and holon attract each other at short distance. The attraction gets stronger as the size of the system is increased and, in the thermodynamic limit, it is responsible for the square root singularity in the hole spectral function.

description: Sample size is often dictated by budget and acceptable error bounds. However, there are many economic problems where sample size directly affects a benefit or loss function, and in these cases, sample size is an endogenous variable. We introduce an economic approach to sample size determination utilizing a Bayesian decision theoretic framework that balances the expected costs and benefits of sampling using a Bayesian prior distribution for the unknown parameters. To demonstrate the method for a relevant applied economics problem, we turn to randomly sampling beef cattle for genetic testing. A theoretical model is developed, and several simplifying assumptions are made to solve the problem analytically. Data from 101 pens (2,796 animals) of commercially-fed cattle are then used to evaluate this solution empirically. Results indicate that at the baseline parameter values an optimal sample size of n^*=10 out of 100 animals generate returns from sampling of nearly $10/head, or a return-on-investment of 250%. Therefore, a large portion of the additional value for higher-quality cattle can be captured by testing a relatively small percentage of the lot. These results vary depending on the actual quality (or profitability) of a particular pen of cattle, the homogeneity within the pen, the variance of the buyer’s subjective prior distribution of expected profit, and the per-head cost of genetic testing. Nonetheless, results suggest that random sampling has the potential to provide a context in which the benefits of genetic testing outweigh the costs, which has not generally been the case in previous research.

description: Abstract: Mental imagery is the process through which we retrieve and recombine information from our memory to elicit the subjective impression of “seeing with the mind’s eye”. In the social domain, we imagine other individuals while recalling our encounters with them or modelling alternative social interactions in future. Many studies using imaging and neurophysiological techniques have shown several similarities in brain activity between visual imagery and visual perception, and have identified frontoparietal, occipital and temporal neural components of visual imagery. However, the neural connectivity between these regions during visual imagery of socially relevant stimuli has not been studied. Here we used electroencephalography to investigate neural connectivity and its dynamics between frontal, parietal, occipital and temporal electrodes during visual imagery of faces. We found that voluntary visual imagery of faces is associated with long-range phase synchronisation in the gamma frequency range between frontoparietal electrode pairs and between occipitoparietal electrode pairs. In contrast, no effect of imagery was observed in the connectivity between occipitotemporal electrode pairs. Gamma range synchronisation between occipitoparietal electrode pairs predicted subjective ratings of the contour definition of imagined faces. Furthermore, we found that visual imagery of faces is associated with an increase of short-range frontal synchronisation in the theta frequency range, which temporally preceded the long-range increase in the gamma synchronisation. We speculate that the local frontal synchrony in the theta frequency range might be associated with an effortful top-down mnemonic reactivation of faces. In contrast, the long-range connectivity in the gamma frequency range along the fronto-parieto-occipital axis might be related to the endogenous binding and subjective clarity of facial visual features.

description: This paper questions the impact of the globalization of the retail sector on the export activity of origin country agri-food firms. In a previous paper (Cheptea et al., 2015), we showed that the overseas expansion of a country’s retailers fostered its exports to foreign markets. This effect can be explained by a reduction in trade costs for retailers’ supplying firms in the origin country, or to a change in consumer preferences in the host country that benefits all origin country firms. In this paper, we evaluate which of the two mechanisms dominates. For that, we use an original firm-level database of French agri-food exports, identifying the domestic suppliers of French retailers through certification with the private IFS standard. We find that IFS certified French firms are more likely to export and export larger volumes than noncertified firms to markets where French retailers established outlets. We also show that when French retailers close down their activities in a market, IFS firms face a drop in exports to this market in the subsequent years. The results are robust to the use of different sets of firm- and country-specific fixed effects, are unaffected by possible selection and endogeneity biases, and by the presence in export markets of other retailers. The difference in behavior for certified and non-certified exporting firms on markets where French retailers operate confirms the trade cost advantage of retailers’ suppliers, which is lost when French retailers exit from the destination country.

description: We have measured deconfined hadronic volumes, $4.4 < V < 13.0$ fm$^{3}$, produced by a one dimensional (1D) expansion. These volumes are directly proportional to the charged particle pseudorapidity densities $6.75 < dN_{c}/dη< 20.2$. The hadronization temperature is $T = 179.5 \pm 5$ (syst) MeV. Using Bjorken's 1D model,the hadronization energy density is $ε_{F} = 1.10 \pm 0.26$ (stat) GeV/fm$^{3}$ corresponding to an excitation of $24.8 \pm 6.2$ (stat) quark-gluon degrees of freedom.
