description: Gas in the interstellar matter is generally organized in filamentary structures, which may be also relevant for a complementary explanation of the dark matter in the Galactic halo. We examine the possibility that such structures may act as gravitational microlenses on background sources. To this purpose, we derive the general properties of a cylindrical lens and compare the light curves produced by such microlensing events with those generated by spherically symmetric clouds. We find that the establishment of the symmetry of the lens through the sole analysis of the light curve may be problematic, while the analysis of the astrometric shift of the centroid of the image can discriminate between the two classes of clouds. On the basis of our analysis, we find that only gas filaments with a very high density could be detectable. Such clouds are unlikely to exist in a long-lived state. Therefore, microlensing cannot discriminate on the existence and the relevance of gas filaments in the Halo, which could well be present and escape detection by ordinary microlensing surveys.

description: Electron backscatter diffraction is a widely used technique for nano- to micro-scale analysis of crystal structure and orientation. Backscatter patterns produced by an alloy solid solution matrix and its ordered superlattice exhibit only extremely subtle differences, due to the inelastic scattering that precedes coherent diffraction. We show that unsupervised machine learning (with PCA, NMF, and an autoencoder neural network) is well suited to fine feature extraction and superlattice/matrix classification. Remapping cluster average patterns onto the diffraction sphere lets us compare Kikuchi band profiles to dynamical simulations, confirm the superlattice stoichiometry, and facilitate virtual imaging with a spherical solid angle aperture. This pipeline now enables unparalleled mapping of exquisite crystallographic detail from a wide range of materials within the scanning electron microscope.

description: Let f: M -> N be an even codimensional immersion between smooth manifolds. We derive an explicit formula for the Pontrjagin numbers and signature of the multiple point manifolds in terms of singular cohomology of M and N, the maps induced between these by f and the characteristic classes of the normal bundle. The main trick is to solve a recursion in cohomology by the use of (generalized) formal power series.

description: This paper analyzes possible improvements to water allocation from introducing weather derivatives as an insurance instrument in irrigation districts with no water markets and two cropping seasons. Dry-season production depends completely on irrigation, while wet-season production depends on irrigation as a supplement to naturally occurring precipitation. Using an analytical model of water allocation and historical data from an irrigation district in Central Mexico, simulations show that weather derivatives could encourage interseasonal reallocation of water from wet to dry season, generating new Pareto-optimal water allocations that improve overall welfare among producers.

description: We initiate an exploration of the conformal bootstrap for $n>4$ point correlation functions. Here we bootstrap correlation functions of the lightest scalar gauge invariant operators in planar non-abelian conformal gauge theories as their locations approach the cusps of a null polygon. For that we consider consistency of the OPE in the so-called snowflake channel with respect to cyclicity transformations which leave the null configuration invariant. For general non-abelian gauge theories this allows us to strongly constrain the OPE structure constants of up to three large spin $J_j$ operators (and large polarization quantum number $l_{j}$) to all loop orders. In $ \mathcal{N}=4$ we fix them completely through the duality to null polygonal Wilson loops and the recent origin limit of the hexagon explored by Basso, Dixon and Papathanasiou.

description: Consumers are increasingly scrutinizing the animal welfare implications of modern agricultural production processes. We used surveys to examine both the U.S. public willingness-to-pay for and dairy farmer willingness-to-supply or change on-farm production practices related to dairy cattle welfare and find that the public has a positive WTP for all practices examined, while most dairy farms already supply those practices (with the exceptions of employee training programs, third-party certification, and outdoor access). Implications for practice verification and premiums are discussed in the context of dairy markets and policy.

description: Despite growing interest in local food, modeling the economic contribution of this endogenous system is inherently problematic. We present a combined hypothetical extraction and import-substitution social accounting matrix model that overcomes these problems in a theoretically consistent and computationally feasible manner. The method can be applied broadly to many different definitions of a “local food system” and uses the same underlying method as traditional economic-base contribution models. We apply this model to the state of Idaho and compare the economic contribution of the local food system against the economic contribution of the export food system.

description: The main obstacle for the generalized use of live posts of gliricidia in the production of passion fruit is the profuse crown growth in gliricidia, which requires frequent lopping. On a 1.5 year-old plantation of passion fruit in Dumbarton, St. Vincent, three treatments were used to control branch development in the gliricidia posts. The two nontraditional treatments, application of 25 cm3 of CULT AR (25% paclobutrazol) and girdling of the posts, resulted in significant reduction of branch production in comparison with the control treatment which consisted of lopping only. Posts treated with CULT AR showed the most drastic reductions in branch growth. No effect of the treatments on post mortality was observed. The new tested treatments have a potential to significantly increase the cost-effectiveness of passion fruit cultivation in the Caribbean.

Triassic reservoir performance in the Heron cluster, ETAP, Central North Sea

Year: 2020
Subjects: subject: Geology
subject: FOS: Earth and related environmental sciences

description: Shell Expro's Heron Cluster fields form part of the Eastern Trough Area Project (ETAP), an integrated development with BP of a total of seven fields. The Heron cluster comprises: Heron (discovered in 1988), Egret (1985) and Skua (1986). These form subsea tiebacks to the Central Processing Facility located over the Marnock Field. The fields are classified as HP/HT reservoirs, with initial pressures and temperatures of 9300-12,900 psi and 300-350 F respectively. The main reservoir within the cluster is the Triassic Skagerrak Formation. Development of these fields initially assumed the Skagerrak would be well connected and likely to have an active aquifer. However, initial production from Heron in 1998 revealed a dramatic pressure decline, indicating that the reservoir was more compartmentalised than anticipated, with little or no aquifer, necessitating a revision to the reservoir model. The Skagerrak can be subdivided into an upper, more channel-dominated interval and a lower, poorer quality, largely unconfined fluvial section, bounded below by the playa Marnock Shale and above by the lacustrine Heron Shale. The section records the progradation of large terminal fluvial systems, and in detail is composed of discrete channel/terminal splay cycles bounded by a hierarchy of shales. The shales have a variety of origins, ranging from perennial to ephemeral lacustrine to variably drained floodplain, and record regional expansion of the floodbasin facies in response to changes in hinterland runoff and sediment yield. These shales form laterally persistent, effective barriers to vertical flow. Additional perforations in compartments bounded by the shales have encountered near virgin pressures and also subtly differing oil compositions. Overall the Skagerrak reservoirs in the Heron Cluster appear to have the following common characteristics: good lateral connectivity, but poor to zero vertical connectivity; large faults become 'leaky' with sufficient pressure drawdown, and there appears to be no aquifer support. The short term production behaviour of these reservoirs is not representative of their longer term behaviour, and in particular, short term well tests indicate a level of compartmentalisation which does not materialise during production.
CMS III - A Carboniferous Westphalian channel sand development in the Southern North Sea

description: This core display consists of samples from various parts of the Westphalian channel sand reservoirs producing as part of the CMS III (Caister-Murdoch System) development in the Southern North Sea. The project consists of production from 6 individual accumulations. The Westphalian CD can be broadly subdivided into three chronostratigraphic units - from the base, these are the Lower Schooner, the Lower Ketch, and the Upper Ketch. The Lower Ketch 2 sub-unit contains the best developed reservoir sands of the Westphalian CD observed in the Boulton B and Hawksley fields. The sands tend to be blocky in log character, and conglomerate is common, especially in the more proximal setting around Hawksley. The Hawksley development well was brought on stream providing a constrained initial rate of 184 MMSCF and a potentially commercial accumulation was identified in the overlying Rotliegendes North Leman Sandstone. The McAdam discovery well 44/17-1 encountered gas in the Murdoch and overlying Westphalian B sandstones. The Watt discovery well 44/22b-8 encountered a gas sand within the Westphalian B . Murdoch K is a wedge of Westphalian C/D fluvial sandstones on the down-thrown side of a major NE-SW trending spoon-shaped Carboniferous normal fault to the SE of Murdoch, with an initial constrained rate of 204 MMSCF. Carboniferous diagenesis is strongly influenced by multi-phase weathering processes. There are repeated episodes of dissolution, quartz cementation and replacement of feldspars by kaolinite. Early quartz cementation has inhibited compaction and preserved high primary porosity which is enhanced by the generation of secondary porosity due to dissolution. Reservoir quality within the Carboniferous sandstones is principally a result of depositional texture. The clean, coarse grained, often conglomeratic channel-fill sandstones exhibit the best permeabilities due to lower cement content and enhanced framework grain dissolution. The flood-related sandstones (crevasse and sheetflood deposits) show poor reservoir quality due to their finer grain size and significantly enhanced ductile content, which has rendered them more susceptible to the effects of compaction.

description: Perennial peanut species Arachis glabrata Benth. (rhizoma peanut) and A. pintoi Krap. et Greg. are promising forage legumes for the tropics. Seventy-seven accessions primarily of the rhizoma species and six A. pintoi were evaluated for adaptation, rate of plant spread, yield, nutritional quality, and persistence in small plots on an Oxisol at the USDA-ARS farm in Isabela, Puerto Rico. Single plant introductions exhibited significant variability in plant density and plant height one year after planting. Selected accessions of rhizoma peanut were evaluated for rate of plant spread, rhizome development, and forage yield. A full-plot cover of rhizoma peanut was obtained between 24 and 36 weeks after planting. Significant variability was detected for rhizome yield, which averaged 3.21 kg m- 2. Crude protein content (CPC) of rhizoma peanut ranged from 163 to I 97 g kg-I and in vitro dry matter digestibility (IVDMD) from 523 to 616 g kg- 1. Dry matter yield (DMY) averaged 1.44 t ha-I at 36 weeks of growth. Introduction plot material subjected to mob grazing was highly acceptable and persistent. Accumulative DMY of 2.2 t ha-I was obtained using 42-day grazing cycles on rhizoma peanut. A. pintoi accessions TARS 17182 and 17186 exhibited excellent plant spread with a full-plot cover at 16 weeks after planting. DMY of the two accessions averaged I.I t ha- 1, and averaged CPC and IVDMD of I 57 and 671 g kg-I, respectively. Generally, pests and diseases were not a major problem. Our findings indicate that these two perennial peanut species offer potential for use as protein banks, special purpose pastures, or in grass/legume associations in livestock production systems for the Caribbean region.

description: The Nevis South Field is operated by Mobil North Sea Ltd (ExxonMobil) in partnership with Amerada Hess Ltd, Shell UK Ltd and OMV (UK) Ltd. It is a sub-sea development tied back to the Beryl Alpha platform that lies 7 km to the east-north-east. First oil was produced in 1996 but the field is still actively being drilled to bring on new reservoirs or maximise recovery from those reservoirs already developed. Structurally the field is relatively simple, being a rotated fault block with beds dipping to the south-west. The Base Cretaceous Unconformity cuts down into the crest of the fault block such that strata are progressively eroded towards the north-east. This has led to the core of the field being Triassic reservoirs with Jurassic reservoirs on the flank. The oldest reservoir in the field is the Triassic Lewis I sequence of fluviolacustrine origin. The core illustrates a prograding lacustrine delta sequence and overlying aggradational fluvial sandstones. The Lewis I contains an unusual heavy oil which is currently being produced via a single, high-angle well. Above this unit lies the Lewis III/IV reservoir which contains the bulk of the hydrocarbons in the field. The Lewis III comprises aggradational fluvial braidplain deposits. The Lewis IV comprises an association of floodplain facies. The Lewis III/IV reservoir is exploited via three crestal producers and two water injectors. The Middle Jurassic Beryl reservoir is a high net/gross tidal channel/tidal bar succession of multi-Darcy permeability. Evacuation of the Beryl oil rim is by three horizontal wells with pressure support supplied by an extensive aquifer. The youngest reservoir comprises mass-flow sandstones of the Middle-Upper Jurassic Heather Formation. These are as yet undeveloped and are not illustrated by the selected cores.

description: With the exception of Marx and Schumpeter, the subjects of “long run” and technical progress have lain dormant from the Classics to the end of World War II. Since then, curiosity has again been aroused on two fronts. The first is from former colonies in development and the second is from a renewed optimism in mature industrial countries. The present article deals with the theory and literature that came about with regards to the latter area. In particular, the author considers the work of Harrod and Kalecki. JEL: O41, O42, E12

description: The work broadens the concept of oil-push inflation by introducing the possibility of inflation-impeti deriving from other primary product sectors. The author argues that strict monetary analysis is less appropriate to analysis of a situation in which real variables assume new magnitudes than to a situation in which monetary aggregates change without any spontaneous changes in real variables. The effects of changes in exchange rates of currencies and changes in food prices and costs within different nations are introduced. The mechanism by which nominal wage-rates increase and the implications of this mechanism for the inflationary process are then considered. JEL: E31

description: We consider multidimensional optimization problems, which are formulated and solved in terms of tropical mathematics. The problems are to minimize (maximize) a linear or nonlinear function defined on vectors over an idempotent semifield, and may have constraints in the form of linear equations and inequalities. The aim of the paper is twofold: first to give a broad overview of known tropical optimization problems and solution methods, including recent results; and second, to derive a direct, complete solution to a new constrained optimization problem as an illustration of the algebraic approach recently proposed to solve tropical optimization problems with nonlinear objective functions.

description: We examine the dependence of a thermodynamic potential of a fluid on the geometry of its container. If motion invariance, continuity, and additivity of the potential are fulfilled, only four morphometric measures are needed to describe fully the influence of an arbitrarily shaped container on the fluid. These three constraints can be understood as a more precise definition for the conventional term "extensive" and have as a consequence that the surface tension and other thermodynamic quantities contain, beside a constant term, only contributions linear in the mean and Gaussian curvature of the container and not an infinite number of curvatures as generally assumed before. We verify this numerically in the entropic system of hard spheres bounded by a curved wall.

Our results are applicable to a wide range of systems including an ideal gas of spinless fermions in one dimension (1D), the Tonks-Girardeau (TG) gas of hard-core bosons, as well as a 1D gas of hard-core anyons. In order to illustrate the utility of our approach, we focus on the TG gas confined to an arbitrary time-dependent trapping potential. In particular, we use the determinant representation of the many-body wave function to characterize the nonequilibrium thermodynamics of the TG gas and obtain exact and computationally tractable expressions---in terms of Fredholm determinants---for the mean work, the work probability distribution function, the nonadiabaticity parameter, and the Loschmidt amplitude. When applied to a harmonically trapped TG gas, our results for the mean work and the nonadiabaticity parameter reduce to those derived previously using an alternative approach. We next propose to use periodic modulation of the trap frequency in order to drive the system to highly non-equilibrium states by taking advantage of the phenomenon of parametric resonance. Under such driving protocol, the nonadiabaticity parameter may reach large values, which indicates a large amount of irreversible work being done on the system as compared to sudden quench protocols considered previously. This scenario is realizable in ultracold atom experiments, aiding fundamental understanding of all thermodynamic properties of the system.

subject: F32, E31, F33

description: Many authors welcomed the shift to floating exchange rates as they expected it to result in lower inflation, unemployment and balance of payments disequilibria. However, the new system exhibits two sharp daily fluctuations of exchange rates, imposing unwelcome risks on enterprises. Thus, the urge towards more stable exchange rates is becoming intense. The paper analyses the gradual stabilisation of exchange rates through the establishment of monetary zones. JEL: F32, E31, F33

description: The work takes up a series of issues pertaining to the monetary interpretation of Friedman and Simons. The authors find that espousal of a monetary rule involves, foremost, confidence in the extrapolability of long-term statistical trends, particularly with respect to velocity. The initial formulation of the monetary hypothesis of the Great Depression is linked to an entirely overlooked original contribution by William Foster and Waddill Catchings. Their contribution these authors essentially anticipates views set forth by Friedman and Simons, and already included the formulation of the monetary growth-rate rule. JEL: B31

Subjects: subject: Formal Languages and Automata Theory (cs.FL)

description: A theorem of Eilenberg establishes that there exists a bijection between the set of all varieties of regular languages and the set of all varieties of finite monoids. In this article after defining, for a fixed set of sorts $S$ and a fixed $S$-sorted signature $Σ$, the concepts of formation of congruences with respect to $Σ$ and of formation of $Σ$-algebras, we prove that the algebraic lattices of all $Σ$-congruence formations and of all $Σ$-algebra formations are isomorphic, which is an Eilenberg's type theorem. Moreover, under a suitable condition on the free $Σ$-algebras and after defining the concepts of formation of congruences of finite index with respect to $Σ$, of formation of finite $Σ$-algebras, and of formation of regular languages with respect to $Σ$, we prove that the algebraic lattices of all $Σ$-finite index congruence formations, of all $Σ$-finite algebra formations, and of all $Σ$-regular language formations are isomorphic, which is also an Eilenberg's type theorem.

subject: F33, G21, F34

description: The growth of international financial intermediation through the Euromarket and other regional financial centres is one of the most remarkable phenomena of the last 15 years. The present work elucidates the nature of international financial activity through a model of financial intermediation. It goes on to underline the potential benefits from risks inherent in the various activities, as well as their healthy and destabilising macroeconomic impact. A deeper understanding of the international financial mechanism should benefit both bankers and regulators. JEL: F33, G21, F34

description: A study of the decays $B^0\to μ^+μ^-$ and $B^0_s\to μ^+μ^-$ has been performed using data corresponding to an integrated luminosity of $25$ fb$^{-1}$ of $7$ TeV and $8$ TeV proton--proton collisions collected with the ATLAS detector during the LHC Run 1. For $B^0$, an upper limit on the branching fraction is set at ${\cal B}(B^0 \to μ^+μ^-) < 4.2 \times 10^{-10}$ at $95\%$ confidence level. For $B^0_s$, the branching fraction ${\cal B}(B^0_s \to μ^+μ^-) = \left( 0.9^{+1.1}_{-0.8} \right) \times 10^{-9}$ is measured. The results are consistent with the Standard Model expectation with a $p$-value of $4.8\%$, corresponding to $2.0$ standard deviations.

description: In the late 70' s, small farmers started growing pineapple, because of the numerous advantages of this crop, particularly a low susceptibility to climatic risks (hurricanes) and guaranteed saleability (canneries) and prices. To respond to this interest and to the need of more technicality, the CIRAD-FLHOR started an operation to provide training and technical assistance. After a preliminary identification of their needs, this operation included thematic meetings, followed by regular farms visits. In all cases, a close relationship has been maintained with every farmer. According to the results of an investigation carried out in 1990, these farmers have reached a high technical and intensification level (optimization of land use and inputs, generalization of ratoon cropping). They are now associated within the ASP A. On a total area of 90 hectares they produce about 15% (i.e. 2000 mt) of the fruits supplied to the largest pineapple cannery of the island. In 1991, a convention between CIRAD-FLHOR, SUAD (official agricultural development service) and ASPA provided the frame to continue this cooperation with the small farmers, with a particular emphasis on socio-economical aspects (reference plots follow-up). ----- Vers la fin des annees 70, des petits planteurs se sont lances dans la culture de I' ananas, qui presente de nombreux a vantages notamment une faible sensibilite aux aleas climatiques (cyclones) et un ecoulement sur a un prix garanti (conserveries). Devant cet engouement, et pour pallier un manque de technicite, le CIRAD-FLHOR a initie en 1981 une operation de formation et d'assistance technique aupres de ces planteurs. Apres une phase preliminaire d'identification des besoins, la methode a consiste a organiser des reunions a themes, relayees par des visites individuelles regulieres. Dans tous Jes cas, un contact etroit avec chacun des planteurs a ete maintenu. Une enquete realisee en 1990 a permis de mettre en evidence Jes progres techniques et le niveau d'intensification atteints par ces planteurs (optimisation du potentiel foncier et des intrants, generalisation du second cycle). Regroupes au sein d'une association (ASPA), ces petits planteurs, exploitent au total 90 ha et assurent environ 15% (i.e 2000 T) de l'approvisionnement de la plus grande conserverie de l'ile. En 1991, ce travail d'encadrement aupres de ces planteurs se poursuit, en partenariat avec le SUAD. Une convention CIRADFLHOR/ SUAD/ASPA formalise Jes actions menees, avec un accent particulier sur Jes aspects socio-economiques (suivi de parcelles de reference).

description: We present a novel framework for motion planning in dynamic environments that accounts for the predicted trajectories of moving objects in the scene. We explore the use of composite signed-distance fields in motion planning and detail how they can be used to generate signed-distance fields (SDFs) in real-time to incorporate predicted obstacle motions. We benchmark our approach of using composite SDFs against performing exact SDF calculations on the workspace occupancy grid. Our proposed technique generates predictions substantially faster and typically exhibits an 81--97% reduction in time for subsequent predictions. We integrate our framework with GPMP2 to demonstrate a full implementation of our approach in real-time, enabling a 7-DoF Panda arm to smoothly avoid a moving robot.

description: A critical review of the agronomic practices performed in pineapple cultivation is conducted. These practices include selection of varieties, propagation, treating of planting materials, land preparation, planting and spacing, fertiliser uses, weed control, pest and disease control, forcing, pruning and harvesting. The practices are closely examined and include how they are conducted, their advantages and setbacks, if any. Post-harvest handling includes preparation for market, packaging, storage and transportation. A new and exciting technique that has a lot of promise for the future of pineapple is also discussed. The technique, known as waxing, is gaining tremendous popularity among pineapple exporters. The export market is dominated by two (2) countries within the Caricom region and extra regional trade accounts for a little more than 0.10 percent of total exports. The major source of transportation is via air-freight. Constraints to the export trade are also stated. Discussion then surrounds several reasons why, though promising, pineapple production has declined in Guyana in recent years. Prospects for the future are then mentioned.
Implementing monetarism: some reflections on the U.K. experience
Creators: name: ROWAN, D.
Publisher: name: PSL Quarterly Review
Year: 2013
Subjects: subject: Monetarist gradualism, monetary policy, implementation, U.K., control
subject: E52, E65

description: Contemporary British macro-economic policy is conceived and rationalised as an exercise in “monetarist gradualism”. The present paper is concerned with the problem of its implementation: that is the extent to which the chosen intermediate target available is a “controllable variable” in the sense required by a “monetarist” monetary policy. Specifically, the author looks at how effective monetary control has been in the U.K, and what would be involved in attempting to formulate a set of monetary arrangements more conducive to an “acceptable” degree of control of £M3.
