description: We show that the B \to X(s) gamma photon energy (E_gamma) spectrum can be reliably computed by resummed perturbation theory. Our calculation is based on Dressed Gluon Exponentiation (DGE) incorporating Sudakov and renormalon resummation. It is shown that the resummed spectrum does not have the perturbative support properties: it smoothly extends to the non-perturbative region E_gamma > m/2, where m is the quark pole mass, and tends to zero near the physical endpoint. The calculation of the Sudakov factor, which determines the shape of the spectrum in the peak region, as well as that of the pole mass, which sets the energy scale, are performed using Principal-Value Borel summation. By using the same prescription in both, the cancellation of the leading renormalon ambiguity is respected. Furthermore, in computing the Sudakov exponent we go beyond the formal next-to-next-to-leading logarithmic accuracy using the large-order asymptotic behavior of the series, which is accurately determined from the relation with the pole mass. Upon matching the resummed result with the next-to-leading order expression we compute the spectrum, obtain its moments as a function of a minimum photon energy cut, analyze sources of uncertainty and show that our predictions are in good agreement with Belle data.

description: The major problem in rural Greece is it depopulation. From 1961 to 1971 the urban population of Greece increased from 43.3 to 53.2 percent, while at the same time its rural population decreased from 43.8 to 35.1 percent. This movement away from farming has reached very high levels in some poor and distant regions of the country. Mani, located on the extreme southern part of continental Greece, is such a region. The urbanization movement, resulting mainly from the lower returns to labor employed in farming, as compared to that employed in most non-farm occupations and from the centralization of industry in the bigger urban centers has resulted in accumulating population near Athens and Salonica, (in 1971, the population of Athens proper was 29.0 percent of the whole country). This concentration, in combination with the country's adverse physical conditions, which limit the substitution of labor for capital in farming, has caused important questions about the demand for and supply of farm products. Various suggestions have been made for decreasing out-migration. Some people argue that a change in crop patterns of some regions and reallocation of their productive resources could achieve a substantial increase in the farm incomes and thus stop or decrease the depopulation. Others believe that the key is the decentralization of industry to increase employment in the rural areas.

description: The quenching of degenerate impurity states in metals generally induces a long-range correlated quantum state known as the Kondo screening cloud. While a macroscopic number of particles clearly take part in forming this extended structure, assessing the number of truly entangled degrees of freedom requires a careful analysis of the relevant many-body wavefunction. For this purpose, we examine the natural single-particle orbitals that are eigenstates of the single-particle density (correlation) matrix for the ground state of two quantum impurity problems: the interacting resonant level model (IRLM) and the single impurity Anderson model (SIAM). As a simple and general probe for few-body versus many-body character we consider the rate of exponential decay of the correlation matrix eigenvalues towards inactive (fully empty or filled) orbitals. We find that this rate remains large in the physically most relevant region of parameter space, implying a few-body character. Genuine many-body correlations emerge only when the Kondo temperature becomes exponentially small, for instance near a quantum critical point. In addition, we demonstrate that a simple numerical diagonalization of the few-body problem restricted to the Fock space of the most correlated orbitals converges exponentially fast with respect to the number of orbitals, to the true ground state of the IRLM. We also show that finite size effects drastically affect the correlation spectrum, shedding light on an apparent paradox arising from previous studies on short chains.

description: Pantecphylus major Griffini was redescribed and regarded as subgenus Griffinius n. subgen. The species is remarkably different from other species of the genus. Only adult females and a young nymph were available. They were separated by the size of body, a bilobate fastigium verticis, the lack of a transverse sulcus of the pronotum, and the presence of two rows of long hairy spines on all femora. The body lenght of adult females was 37-38 mm, the females of the other species measuring no more than 34 mm.

description: Industrialization and development increase the demand for information. Specialization of functions and organization also greatly increases the need for coordination and thus the social returns to and demand for information. Agricultural information systems are useful to 1) the government officials dealing with food policy and agriculture, including the central bankers, and enterprises in the public sector; 2) the private sector; and 3) the donors and international organizations. The basic focus of this paper is to review the state of knowledge about the process of improving agricultural market information for both private and public sector uses in developing countries. This involves the question of whether it is wise to invest resources in information services rather than in alternatives like infrastructures. The aim is the improvement of the market coordination of existing firms in the food system. This paper will bring the attention of government officials and rural development personnel to the collection, analysis and dissemination of agricultural information.

description: The present work provides a general survey of the scorpion genus Euscorpius Thorell, 1876. Each species is briefly summarized, with notes on taxonomy, morphology, geographic distribution and ecology. The distribution and diagnostic characters are shown in easy to read tables and an identification key is provided. All the current valid species of Euscorpius (except Euscorpius koschewnikowi Birula, 1903) and several peculiar morphotypes are illustrated, with the first images of Euscorpius beroni Fet, 2000. The main aim of this work is to provide a complete review which will be useful both to have clearance on current systematics of the complex genus Euscorpius and to interpret possible future taxonomic rearrangements. Euscorpius italicus (Herbst, 1800) was found for the first time in Siena (central-western Italy), a record that represents a new allochthonous population, probably due to anthropogenic origin.

description: African capacity building was first identified as a major development problem during the transition to independence in the 1950s. After billions of dollars of investment in education over the past three decades, capacity building has been identified as one of Africa's most serious development problem of the 1990s. This paper analyzes African capacity building experiences over the last four decades. It focuses on the treatment of African capacity building by colonial powers, African governments, donors, and international agencies during the transition to independence in the 1950s and the post independence period since 1960. Nigeria and Kenya are used as case studies to highlight some of the key issues and draw some lessons for South Africa. Capacity building in this study focuses on the development and strengthening of education and decision-making skills required for sustainable economic development. Attention is focused on both the supply and demand sides of capacity building, namely education expansion and absorptive capacity of the economy (i.e employment creation). Key findings include the following: Uncompromising political and economic demands for education at independence in the 1960s led to a massive expansion of education at all levels, beginning with universal free primary education in the 1960s, followed by the expansion of secondary and university education in the 1970s. Manpower training programs focused on the urgent Africanization of the civil service. However, after a major expansion of education from 1960 to 1980, problems emerged in the 1980s, including an intolerable level of government expenditure on education, declining education quality and relevance, and inability to absorb school leavers and curb the brain drain. Donors and international agencies have increasingly come under fire for paying insufficient attention to African capacity building while overemphasizing the provision of physical infrastructure which they assumed to be the "missing factor". These projects promised quick, visible, and measurable results but required crisis management. Technical assistance has also come under scrutiny. The new African Capacity Building Initiative was established to redress capacity problems in Africa. Six lessons flow from this analysis for South Africa: (1) The hard trade-offs between elimination of illiteracy (i.e primary education expansion) and university education expansion, (2) The burden of financing the expansion of education, (3) The high cost of education per student, (4) Absorptive capacity of the economy, (5) Effects of education expansion on quality and relevance of education , and (6) The selective borrowing of skills from the international community in nation building.

description: The similarity in fractal dimensions of paint ``blobs'' in samples of gestural expressionist art implies that these pigment structures are statistically indistinguishable from one another. This result suggests that such dimensions cannot be used as a ``fingerprint'' for identifying the work of a single artist. To overcome this limitation, the multifractal spectrum is adopted as an alternative tool for artwork analysis. For the pigment blobs, it is demonstrated that this spectrum can be used to isolate a construction paradigm or art style. Additionally, the fractal dimensions of edge structures created by luminance gradients on the canvas are analyzed, yielding a potential method for visual discrimination of fractally-similar paintings.

description: Resource theories provide a general framework for the characterization of properties of physical systems in quantum mechanics and beyond. Here, we introduce methods for the quantification of resources in general probabilistic theories (GPTs), focusing in particular on the technical issues associated with infinite-dimensional state spaces. We define a universal resource quantifier based on the robustness measure, and show it to admit a direct operational meaning: in any GPT, it quantifies the advantage that a given resource state enables in channel discrimination tasks over all resourceless states. We show that the robustness acts as a faithful and strongly monotonic measure in any resource theory described by a convex and closed set of free states, and can be computed through a convex conic optimization problem. Specializing to continuous-variable quantum mechanics, we obtain additional bounds and relations, allowing an efficient computation of the measure and comparison with other monotones. We demonstrate applications of the robustness to several resources of physical relevance: optical nonclassicality, entanglement, genuine non-Gaussianity, and coherence. In particular, we establish exact expressions for various classes of states, including Fock states and squeezed states in the resource theory of nonclassicality and general pure states in the resource theory of entanglement, as well as tight bounds applicable in general cases.

description: Abstract

Introduction: Systemic lupus Erythematosus (SLE) is an auto-immune disease with multisystem involvement. Gastrointestinal involvement is fairly common in patients of SLE. Acute pancreatitis is a rare presenting feature among patients with SLE. SLE related pancreatitis has an annual incidence of 0.4-1.1 per thousand patients, occurring in 0.5-0.9% of patients with SLE. Case description: A 24-year-old male, presented to the emergency of Sharda Hospital, Greater Noida with complaints of vomiting and pain in abdomen for 2 days, dysphagia and fever since 1 month, oral ulcers since 2 months. At the time of admission patient was treated as a case of Acute pancreatitis with AKI. However, as more investigations became available and patient showed no significant clinical improvement an ANA (IFA) was sent. ANA was moderately positive and the ANA profile was strongly positive for Anti SM antibody, Ds DNA antibody and RNP-Sm antibody. Patient met the EULAR/ACR criteria for SLE and was treated with systemic steroids (methylprednisolone). Patients clinical condition improved and his liver functions and amylase/lipase normalized. Patient was discharged in satisfactory condition after a 2 week stay on HCQs and oral steroids. At 4 week follow up patient remained asymptomatic albeit a few occasional oral ulcers. Conclusion: SLE associated acute pancreatitis is a rare but known complication of SLE. In a patient of acute pancreatitis without any apparent cause SLE should be evaluated in presence of supporting clinical features like leukopenia, rash, ulcers etc. A strong index of suspicion should be maintained in such patients as they have a higher mortality and morbidity.

description: What difference does it make whether farmers are served by cooperatives or investor owned firms? Are these two forms of organizations really different? Cooperative ownership principles result in owners being more interdependent and interactive with managers of the work organization than do investor ownership principles. This difference results in a difference in manager roles and cooperative firm behavior unless the interdependence and interaction is offset by technological constraints, complexity, product diversity, and rate of change in the environment. Institutional Analysis and Organizational Behavior-Contingency Theory are used to link the influence of ownership principles and task environment to managerial role behavior.

description: We report interferometric observations of the semi-regular variable star RS CrB, a red giant with strong silicate emission features. The data were among the first long baseline mid-infrared stellar fringes obtained between the Keck telescopes, using parts of the new nulling beam combiner. The light was dispersed by a low-resolution spectrometer, allowing simultaneous measurement of the source visibility and intensity spectra from 8 to 12 microns. The interferometric observations allow a non-ambiguous determination of the dust shell spatial scale and relative flux contribution. Using a simple spherically-symmetric model, in which a geometrically thin shell surrounds the stellar photosphere, we find that ~30% to ~70% of the overall mid-infrared flux - depending on the wavelength - originates from 7-8 stellar radii. The derived shell opacity profile shows a broad peak around 11 microns (tau ~ 0.06), characteristic of Mg-rich silicate dust particles.

Inscribing Ireland : Place-names and the author/ity of the Ordnance Survey (1824-1846)
Creators: name: Gilchrist, Elizabeth Anne
Publisher: name: University of British Columbia
Year: 2009

description: In 1825, two detachments of Royal Engineers were dispatched from their English headquarters and sent to Dublin to undertake the first Ordnance Survey of Ireland. This Survey aimed to set new standards for topographical mapping: however there was an anxiety to make the maps a standard of orthography as well as of topography. Placenames were to be examined and 'rectified' with the same ardour for precision as all other aspects of the Survey. This thesis examines the textual processes by which the Ordnance Survey's journey through Ireland resulted in its place-names becoming fixed in print. From detailed readings of original documents of the Ordnance Survey I reconstruct the principles, policies and methods by which the surveyors collected and edited placenames for publication on the Ordnance Survey maps. I trace how orthographic knowledge was produced, manipulated and negotiated within the analytical spaces of the Ordnance Survey documentation. Having reconstructed the Survey's orthographic procedures I consider what the overall effect these various policies and practices was on the Irish namescape at large. I argue that the fixing of Ireland's place-names on the Ordnance Survey maps systematically modified these names. More specifically I argue that the Ordnance Survey anglicised Ireland's place-names. Upon its completion in 1846, this cartographic operation had accomplished more than the production of a "representation of land on paper." These maps of the Irish Survey constructed a particular vision of Ireland through very particular modes of representation. This cartographic construction of Ireland comprised a profoundly pragmatic and politicised discourse. I situate the Survey's naming practices within the broader political context of English-Irish relations. The Ordnance Survey and its orthographic practices in particular are argued throughout this work to be important constituents of England's apparatus for extending political, cultural and economic control over Ireland during the nineteenth century.

description: This study addresses unsupervised subword modeling, i.e., learning acoustic feature representations that can distinguish between subword units of a language. We propose a two-stage learning framework that combines self-supervised learning and cross-lingual knowledge transfer. The framework consists of autoregressive predictive coding (APC) as the front-end and a cross-lingual deep neural network (DNN) as the back-end. Experiments on the ABX subword discriminability task conducted with the Libri-light and ZeroSpeech 2017 databases showed that our approach is competitive or superior to state-of-the-art studies. Comprehensive and systematic analyses at the phoneme- and articulatory feature (AF)-level showed that our approach was better at capturing diphthong than monophthong vowel information, while also differences in the amount of information captured for different types of consonants were observed. Moreover, a positive correlation was found between the effectiveness of the back-end in capturing a phoneme's information and the quality of the cross-lingual phone labels assigned to the phoneme. The AF-level analysis together with t-SNE visualization results showed that the proposed approach is better than MFCC and APC features in capturing manner and place of articulation information, vowel height, and backness information. Taken together, the analyses showed that the two stages in our approach are both effective in capturing phoneme and AF information. Nevertheless, monophthong vowel information is less well captured than consonant information, which suggests that future research should focus on improving capturing monophthong vowel information.

description: A survey conducted in central Italy found 126 species of phytophagous insects from five orders and 25 families on dyer’s woad, Isatis tinctoria L., a biennial or short-lived perennial. About 75% of the species found attacking this weed were polyphagous, 20% were restricted to the family Brassicaceae, and only 5% were restricted to the genus Isatis. Four of the one hundred twenty six species recovered were specific enough to merit further research as candidates for biological control of I. tinctoria L. in the United States. Preliminary host range tests were conducted for the weevils Ceutorhynchus rusticus Gyllenhal, Ceutorhynchus peyerimoffi Hustache, Aulacobaris fallax (H. Brisout), and the fleabeetle Psylliodes isatidis Heikertinger. All tests were conducted at the USDA-ARS-EBCL Rome substation from 2003 to 2006 and are reported herein.

description: Static economic theory views the production and consumption sides of the economic environment separately as two unique activities. The distinction between the business and home aspects in the case of farming arose in economic theory and principles of analysis, especially because static theory assumes perfect knowledge, perfect foresight and the absence of change in production techniques and consumption patterns, and overlooks their interrelationships and interdependence when farmers are viewed both as producers and consumers. A great number of personal values, wants, and desires are encountered on the production side of farming and a major part of management consists of appraising the subjective costs and values of performing the various managerial functions. On the other hand, a great deal of production is recognized to be occurring on the household side of farming. Therefore, it was then realized that the distinctions maintained between the business and home sides of farming were artificial and unrealistic. As a result the distinction between the firm and household became increasingly confused and less meaningful. This basic understanding of the basic nature of operation of farm households led to the development of holistic or comprehensive farm management research and extension activities in the middle part of this century. In the subsequent period, these programs and the holistic focus on firm-household interrelationships in farming were delegated a somewhat reduced role in the research and extension activities. Recently, however, there has been a growing interest among general and development economists in this concept of firm-household behavior, and the related research and extension programs. For the most part the development has ignored past and present emphasis on firm-household interrelationships in the traditional field of farm management. It is the intention of this paper to emphasize the importance of making use of the valuable research and extension knowledge gained in the U.S. through the development of the holistic farm and home programs and the need to incorporate these concepts and the learning experiences into the newly developing methodology of Farming Systems Research.

Migrations are an intrinsic aspect of human societies, past and present. This global character can be used to build a comparative anthropological framework seeking to understand the drivers and consequences of migration. Within this agenda, we seek to comprehend what are the causes and social effects of a rapid migration pulse recorded between AD 1270-1420 in the southern Andes (Uspallata Valley, 32ºS, Mendoza, Argentina), shortly preceding the Inka conquest. We will develop a bottom-up approach to human life-histories linking the micro-scale of the individual with the level of households, communities, and larger social groups. This will be based on an interdisciplinary bioarchaeological approach to burial sites in Uspallata, combining the analysis of intra-individual stability and inter-individual diversity in diet and residence as measured by stable and radiogenic isotopes, the demographic profiles of the sites with migrants and locals, causes of the death, and biological distances as revealed by paleogenomics. We contend that the life-history approach allows bridging scales between short-term contemporary approaches to migration studies and deep time diachronic studies of migration and cultural change. By building on this case-study we will foster a comparative approach to life-histories, lineages, and migrations in the southern Andes and beyond.

description: In all Friedman models, the cosmological redshift is widely interpreted as a consequence of the general-relativistic phenomenon of EXPANSION OF SPACE. Other commonly believed consequences of this phenomenon are superluminal recession velocities of distant galaxies and the distance to the particle horizon greater than c*t (where t is the age of the Universe), in apparent conflict with special relativity. Here, we study a particular Friedman model: empty universe. This model exhibits both cosmological redshift, superluminal velocities and infinite distance to the horizon. However, we show that the cosmological redshift is there simply a relativistic Doppler shift. Moreover, apparently superluminal velocities and `acausal' distance to the horizon are in fact a direct consequence of special-relativistic phenomenon of time dilation, as well as of the adopted definition of distance in cosmology. There is no conflict with special relativity, whatsoever. In particular, INERTIAL recession velocities are subluminal. Since in the real Universe, sufficiently distant galaxies recede with relativistic velocities, these special-relativistic effects must be at least partly responsible for the cosmological redshift and the aforementioned `superluminalities', commonly attributed to the expansion of space. Let us finish with a question resembling a Buddhism-Zen `koan': in an empty universe, what is expanding?

description: We review recent results on the role of light quark states within the QCD phase diagram. In particular, we will discuss how the combined use of theoretical techniques such as Effective Theories, Unitarization and Ward Identities helps to shed light on several important issues regarding chiral symmetry restoration, building bridges with recent lattice analyses. Special attention will be paid to the role of chiral and $U(1)_A$ partners in the interplay between those symmetries, which is crucial to properly understand the transition pattern. Light scalar mesons at finite temperature will be shown to be responsible for the description of susceptibilities encoding chiral and $U(1)_A$ restoration properties.

description: This paper presents the results of field interviews conducted in the Fall of 1965 and Winter of 1966 among Puerto Rican farmers, truckers, and processors. Each type of respondent was asked questions which were appropriate to his occupation, but all interviews were composed of four general sections: (1) economic aspects of the firm or operation, (2) personal characteristics of the operators, (3) attitudes toward economic environment and modernization, and (4) communication habits of the respondents. The results of the survey were confined to the western end of the island in the Mayaguez region. The area was chosen because the Department of Agriculture had initiated their regional plan for agricultural program coordination there. Therefore, considerable information was available from previous studies in the region. Also, the producer marketing associations described and analyzed elsewhere were concentrated in the Mayaguez area. Thus, it was possible to observe and compare association member farmers and non-member farmers.

description: The benefits of an objective method of describing beef carcasses are being investigated through trials at several Australian abattoirs. This paper reports the results of an attitudinal study carried out with the beef retailers who trade with one of these abattoirs. Most retailers surveyed were receptive to the idea of an objective classification system and felt that it would be useful to them in carcass trading. However, other findings raised doubts about the ability of the system being trialed to meet their requirements. The results had a number of implications for the planning of specific aspects of this classification trial.

description: To describe the high harmonic generation at plasma surfaces in the relativistic regime, we introduce the concept of {\it apparent reflection point} (ARP). It appears to an external observer that the radiation electric field is zero at the ARP. The relativistic dynamics of the ARP completely defines the generation of high harmonics and attosecond pulses. The ARP velocity is a smooth function of time. The corresponding $γ$-factor, however, has sharp spikes at the times when the tangential vector potential vanishes and the surface velocity becomes close to the speed of light. We show that managing the laser polarization, one can efficiently control the ARP dynamics, e.g., to gate a single (sub-)attosecond pulse out of the short pulse train generated by a multi-cycle driver. This relativistic control is demonstrated numerically by particle-in-cell simulations.

description: We report the simultaneous quasi-phase-matching of all three possible nonlinearities for propagation along the X axis of periodocally poled (PP) KTiOPO4 (KTP) for second-harmonic generation of 745 nm pulsed light from 1490nm subpicosecond pulses in a PPKTP crystal with a 45.65 micrometer poling period. This confirms the recent Sellmeier fits of KTP by K. Kato and E. Takaoka [Appl. Opt. 41, 5040 (2002)]. Such coincident nonlinearities are of importance for realizing compact sources of multipartite continuous-variable entanglement [Pfister et al., Phys. Rev. A 70, 020302 (2004)] and we propose a new simpler method for entangling four fields, based on this triple coincidence.

Those for Salassa katschinica Bryk, 1944, Cricula zubsiana Nässig, 1985, Actias winbrechlini Brechlin, 2007 and Loepa diversiocellata Bryk, 1944 are notheworthy records. Indeed, Cricula zubsiana is reported for the first time for this country. Salassa katschinica was apparently known only on the typical series. New records for the recent described Actias winbrechlini are reported. The true identity of Loepa diversiocellata is briefly discussed on the basis of comparisons of the holotype with recently collected specimens.

description: We investigate the possibility to observe the QCD critical point in A+A collisions at the SPS. Guided by the QCD phase diagram expressed in experimentally accessible variables we suggest that the process C+C at 158 GeV/n freezes out very close to the critical point. We perform an analysis of the available preliminary experimental data for a variety of SPS processes. The basic tool in our efforts is the reconstruction of the critical isoscalar sector which is formed at the critical point. Our results strongly support our proposition regarding the C+C system.

description: Probability judgements are important components of decision making under uncertainty. In particular, economic decisions can be aided by assuring more accurate assessment of probabilities and more realistic modelling of economic problems through the inclusion of subjective probabilities. The purpose of this paper is to describe the techniques which can be used to elicit subjective probabilities and the ways in which these techniques can be incorporated into agricultural economics research. The review draws from the statistics, psychology, management, operations research, meteorology and economics literature.

description: The lightcurves of variable DA stars are usually multi-periodic and non-sinusoidal, so that their Fourier transforms show peaks at eigenfrequencies of the pulsation modes and at sums and differences of these frequencies. These combination frequencies provide extra information about the pulsations, both physical and geometrical, that is lost unless they are analyzed. Several theories provide a context for this analysis by predicting combination frequency amplitudes. In these theories, the combination frequencies arise from nonlinear mixing of oscillation modes in the outer layers of the white dwarf, so their analysis cannot yield direct information on the global structure of the star as eigenmodes provide. However, their sensitivity to mode geometry does make them a useful tool for identifying the spherical degree of the modes that mix to produce them. In this paper, we analyze data from eight hot, low-amplitude DAV white dwarfs and measure the amplitudes of combination frequencies present. By comparing these amplitudes to the predictions of the theory of Goldreich & Wu, we have verified that the theory is crudely consistent with the measurements. We have also investigated to what extent the combination frequencies can be used to measure the spherical degree (ell) of the modes that produce them. We find that modes with ell > 2 are easily identifiable as high ell based on their combination frequencies alone. Distinguishing between ell=1 and 2 is also possible using harmonics. These results will be useful for conducting seismological analysis of large ensembles of ZZ Ceti stars, such as those being discovered using the Sloan Digital Sky Survey. Because this method relies only on photometry at optical wavelengths, it can be applied to faint stars using 4 m class telescopes.
