description: A Közös Agrárpolitika bevezetése óta komoly változásokon ment keresztül. Jelenleg ezek hétévente követik egymást, amelyek közül a legutóbbi alapvető vál-tozás 2013-ban történt a 2014–2020-as időszakra vonatkozóan. A döntéshozók emellett megegyeztek egy félidős felülvizsgálatban is, hogy értékelni lehessen a bevezetett számos új rendelet hatásait. A Bizottság kidolgozott egy értékelési módszertant és már publikált is néhány anyagot az előző időszakokra vonatkozó előzetes eredményekből. A jelen írás áttekinti, hogy a Bizottság által használt módszertan és az adatbázis összhangban van-e a legmagasabb szintű agrárpoli-tikai értékelési standardokkal. = The Common Agricultural Policy has changed significantly over time. Major chang-es are now introduced every seven years, with the last fundamental change agreed upon in 2013 for the period 2014-2020. Policymakers also agreed to a mid-term review in order to evaluate the performance of numerous new regulations. The Commission has elaborated a methodology for the evaluation and has already pub-lished some documents with initial results for past periods. This article reviews whether the methodology and database used by the Commis-sion are in line with the highest standards for policy evaluation.

description: The collapse of the protostellar envelope results in the growth of the protostar and the development of a protoplanetary disk, playing a critical role during the early stages of star formation. Characterizing the gas infall in the envelope constrains the dynamical models of star formation. We present unambiguous signatures of infall, probed by optically thick molecular lines, toward an isolated embedded protostar, BHR 71 IRS1. The three dimensional radiative transfer calculations indicate that a slowly rotating infalling envelope model following the "inside-out" collapse reproduces the observations of both HCO$^{+}$ $J=4\rightarrow3$ and CS $J=7\rightarrow6$ lines, and the low velocity emission of the HCN $J=4\rightarrow3$ line. The envelope has a model-derived age of 12000$\pm$3000 years after the initial collapse. The envelope model underestimates the high velocity emission at the HCN $J=4\rightarrow3$ and H$^{13}$CN $J=4\rightarrow3$ lines, where outflows or a Keplerian disk may contribute. The ALMA observations serendipitously discover the emission of complex organic molecules (COMs) concentrated within a radius of 100 au, indicating that BHR 71 IRS1 harbors a hot corino. Eight species of COMs are identified, including CH$_{3}$OH and CH$_{3}$OCHO, along with H$_{2}$CS, SO$_{2}$ and HCN $v_{2}=1$. The emission of methyl formate and $^{13}$C-methanol shows a clear velocity gradient within a radius of 50 au, hinting at an unresolved Keplerian rotating disk.

Since that time the technique has blossomed as a powerful tool utilizing vastly improved neutron instrumentation coupled with more powerful pulsed sources. Here we review representative experiments illustrating some of the fascinating physics that has been revealed in quasi-one and two dimensional systems

description: Application of Bardeen's tunneling theory to magnetic tunnel junctions having a general degree of atomic disorder reveals the close relationship between magneto-conduction and voltage-driven pseudo-torque, as well as the thickness dependence of tunnel-polarization factors. Among the results: 1) The torque generally varies as sin theta at constant applied voltage. 2) Whenever polarization factors are well defined, the voltage-driven torque on each moment is uniquely proportional to the polarization factor of the other magnet. 3) At finite applied voltage, this relation predicts significant voltage-asymmetry in the torque. For one sign of voltage the torque remains substantial even when the magnetoconductance is greatly diminished. 4) A broadly defined junction model, called ideal middle, allows for atomic disorder within the magnets and F/I interface regions. In this model, the spin dependence of a state-weighting factor proportional to the sum over general state index of evaluated within the (e.g. vacuum) barrier generalizes the local state density in previous theories of the tunnel-polarization factor. 5) For small applied voltage, tunnel-polarization factors remain legitimate up to first order in the inverse thickness of the ideal middle. An algebraic formula describes the first-order corrections to polarization factors in terms of newly defined lateral auto-correllation scales.

Számításaink nem tudták igazolni, hogy a mezőgazdaság hozzájárult volna a gazdasági növekedéshez, ugyanakkor a fordított irányú kapcsolat nem utasítható el, azaz a gazdasági növekedés húzóerőt jelenthet a mezőgazdaság számára. Eredményeink általánosításának két korlátja van: egyrészt a korábbi kutatásokhoz képest rövidebb időszakot vizsgáltunk, másrészt további változók bevonása szükséges a mezőgazdaság szerepének jobb megértéséhez a gazdasági fejlődésben. = The aim of the paper is to analyse whether agriculture can an engine for economic growth in Central and Eastern European countries using data for period between 1990 and 2011. Our calculations do not support the positive contribution of agricul-ture to economic growth. However, we can not reject the opposite causal direction, namely economic growth has positive impact on the agriculture. Interpretation of results has two serious limitations. First, period in question is shorter than previous research. Second, it should be introduced additional variables into analysis to better understanding of agriculture in economic development.

title: Photoreception in Ambulacraria: A Comprehensive Approach
Creators: name: Valero Gracia, Alberto
Publisher: name: The Open University
Year: 2019

description: Non-directional photoreceptors are the evolutionary precursors of all animal eyes; they enable the monitoring of ambient light intensity and regulate feeding, movement and reproduction. While the first animals were most likely benthic, they evolved larval stages very early on, thus conquering a new ecological niche: the pelagic. In this realm, the evolutionary pressure to prey but not be preyed upon became stronger. This implied strong selection for better sensory systems, including photoreception. How were the photoreceptor systems of the earliest primary larvae arranged? Did this system mediate vertical migration, the largest movement of biomass on Earth? To try to answer these questions, I chose the pluteus larva of the sea urchin as a model. A comprehensive array of techniques was applied, covering levels of organization from genes to behaviour. The diversity of opsins in Ambulacraria (echinoderms plus hemichordates) has been surveyed to have the first phylogenetic context on this matter (Chapter 1). A nondirectional photoreceptor based on Go-opsins has been first described in an invertebrate larva of the deuterostome lineage (Chapter 2). A novel custom built behavioural set up was created to investigate the vertical migration of these pluteus larvae under different light conditions (Chapter 3). Based on these findings, a mechanistic model for understanding simple photodetection is proposed.

description: The Kondo-Heinsberg chain is an interesting model of a strongly correlated system which has a broad superconducting state with pair-density wave (PDW) order. Some of us have recently proposed that this PDW state is a symmetry-protected topological (SPT) state, and the gapped spin sector of the model supports Majorana zero modes. In this work, we reexamine this problem using a combination of numeric and analytic methods. In extensive density matrix renormalization group calculations, we find no evidence of a topological ground state degeneracy or the previously proposed Majorana zero modes in the PDW phase of this model. This result motivated us to reexamine the original arguments for the existence of the Majorana zero modes. A careful analysis of the effective continuum field theory of the model shows that the Hilbert space of the spin sector of the theory does not contain any single Majorana fermion excitations. This analysis shows that the PDW state of the doped 1D Kondo-Heisenberg model is not an SPT with Majorana zero modes.

The Sierra Ballena Shear Zone in the southernmost Dom Feliciano Belt (Uruguay): evolution, kinematics, and deformation conditions

Publisher: name: Springer-Verlag

description: The Sierra Ballena Shear Zone (SBSZ) is part of a high-strain transcurrent system that divides the Neoproterozoic Dom Feliciano Belt of South America into two different domains. The basement on both sides of the SBSZ shows a deformation stage preceding that of the transcurrent deformation recognized as a high temperature mylonitic foliation associated with migmatization. Grain boundary migration and fluid-assisted grain boundary diffusion enhanced by partial melting were the main deformation mechanisms associated with this foliation. Age estimate of this episode is >658 Ma. The second stage corresponds to the start of transpressional deformation and the nucleation and development of the SBSZ. During this stage, pure shear dominates the deformation, and is characterized by the development of conjugate dextral and sinistral shear zones and the emplacement of syntectonic granites. This event dates to 658–600 Ma based on the age of these intrusions. The third stage was a second transpressional event at about 586 to <560 Ma that was associated with the emplacement of porphyry dikes and granites that show evidence of flattening. Deformation in the SBSZ took place, during the late stages, under regional low-grade conditions, as indicated by the metamorphic paragenesis in the supracrustals of the country rocks. Granitic mylonites show plastic deformation of quartz and brittle behavior of feldspar. A transition from magmatic to solid-state microstructures is also frequently observed in syntectonic granites. Mylonitic porphyries and quartz mylonites resulted from the deformation of alkaline porphyries and quartz veins emplaced in the shear zone. Quartz veins reflect the release of silica associated with the breakdown of feldspar to white mica during the evolution of the granitic mylonites to phyllonites, which resulted in shear zone weakening. Quartz microstructures characteristic of the transition between regime 2 and regime 3, grain boundary migration and incipient recrystallization in feldspar indicate deformation under lower amphibolite to upper greenschist conditions (550–400°C). On the other hand, the mylonitic porphyries display evidence of feldspar recrystallization suggesting magmatic or high-T solid-state deformation during cooling of the dikes.
Inter-Network magnetic fields observed during the minimum of the solar cycle

description: We analyze a time series of high angular resolution magnetograms of quiet Sun Inter-Network (IN) magnetic fields. These magnetograms have a spatial resolution better than 0.5 arcsec, a noise of some 20 G, and they have been obtained at the disk center during the minimum of the solar cycle. The IN regions show a typical unsigned flux density of the order of 15 G. Signals occur, preferentially, in the intergranular lanes, and the strongest signals trace a network with a scale similar to the mesogranulation. All these features are consistent with the IN magnetograms by Dominguez Cernena et al., obtained during the maximum of the solar cycle. Consequently, the unsigned magnetic flux of the structures that give rise to the IN polarization signals does not seem to undergo large variations during the solar cycle.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: We study global-in-time dynamics of the stochastic nonlinear wave equations (SNLW) with an additive space-time white noise forcing, posed on the two-dimensional torus. Our goal in this paper is two-fold. (i) By introducing a hybrid argument, combining the $I$-method in the stochastic setting with a Gronwall-type argument, we first prove global well-posedness of the (renormalized) cubic SNLW in the defocusing case. Our argument yields a double exponential growth bound on the Sobolev norm of a solution. (ii) We then study the stochastic damped nonlinear wave equations (SdNLW) in the defocusing case. In particular, by applying Bourgain's invariant measure argument, we prove almost sure global well-posedness of the (renormalized) defocusing SdNLW with respect to the Gibbs measure and invariance of the Gibbs measure.

description: We report the discovery of the first short period binary in which a hot subdwarf star (sdOB) fills its Roche lobe and started mass transfer to its companion. The object was discovered as part of a dedicated high-cadence survey of the Galactic Plane named the Zwicky Transient Facility and exhibits a period of $P_{\rm orb}=39.3401(1)$ min, making it the most compact hot subdwarf binary currently known. Spectroscopic observations are consistent with an intermediate He-sdOB star with an effective temperature of $T_{\rm eff}=42,400\pm300$ K and a surface gravity of $\log(g)=5.77\pm0.05$. A high-signal-to noise GTC+HiPERCAM light curve is dominated by the ellipsoidal deformation of the sdOB star and an eclipse of the sdOB by an accretion disk. We infer a low-mass hot subdwarf donor with a mass $M_{\rm sdOB}=0.337\pm0.015$ M$_\odot$ and a white dwarf accretor with a mass $M_{\rm WD}=0.545\pm0.020$ M$_\odot$. Theoretical binary modeling indicates the hot subdwarf formed during a common envelope phase when a $2.5-2.8$ M$_\odot$ star lost its envelope when crossing the Hertzsprung Gap. To match its current $P_{\rm orb}$, $T_{\rm eff}$, $\log(g)$, and masses, we estimate a post-common envelope period of $P_{\rm orb}\approx150$ min, and find the sdOB star is currently undergoing hydrogen shell burning. We estimate that the hot subdwarf will become a white dwarf with a thick helium layer of $\approx0.1$ M$_\odot$ and will merge with its carbon/oxygen white dwarf companion after $\approx17$ Myr and presumably explode as a thermonuclear supernova or form an R CrB star.

Des enquêtes ont été menées en 2009, auprès de 300 producteurs de riz de 10 villages rizicoles de sélection variétale participative. La méthode de l'effet moyen du traitement (ATE) a permis de déterminer un taux commun d’exposition et d’adoption des NERICA de 17% en 2008 et un taux potentiel d’adoption de 37%. Ceci montre qu’il existe un écart d'adoption de 20% lié à la diffusion incomplète des NERICA qu'il faut combler en menant davantage d’actions de diffusion de ces variétés. Le contact avec la recherche agricole constitue le principal facteur déterminant de l'exposition et de l'adoption des NERICA au Burkina Faso. --- This paper aims to assess the actual and potential adoption rate of NERICA (New Rice for Africa) rice varieties and identify the determinants of their diffusion and adoption in Burkina Faso. The surveys were conducted in 2009 among 300 rice farmers in 10 villages participating in the rice varietal selection tests. The average treatment effect (ATE) method made it possible to determine a common rate of exposure to and adoption of NERICA of 17% in 2008, and a potential adoption rate of 37%. This means that there is an adoption gap of 20% due to the incomplete diffusion of NERICA, which must be addressed by carrying out more actions to disseminate these varieties. The contact with agricultural research services is a key factor determining the awareness and adoption of NERICA in Burkina Faso.

description: The infinite color-Coulomb energy of color-charged states is related to enhanced density of near-zero modes of the Faddeev-Popov operator in Coulomb gauge. We confirm the enhancement in numerical simulations and show that it is tied to the presence of percolating center vortex configurations.

description: This study documents the chemical and textural responses of zircon in the Elba igneous complex, with particular reference to the 7- to 7.8-Ma-old Monte Capanne pluton in relation to its coeval volcanic counterpart (Capraia), using BSE imaging and quantitative electron microprobe analyses. The Monte Capanne pluton displays multiple field and geochemical evidence for magma mixing. The samples we have investigated (including monzogranitic, mafic enclave and dyke samples) display similar zircon textures and are associated with an extremely large range of trace and minor element (Hf, Y, HREE, Th, U) compositions, which contrast with relatively simple textures and zoning patterns in zircons from a Capraia dacite. We have used a relatively simple textural classification (patchy zoning, homogenous cores, oscillatory zoning and unzoned zircon) as the basis for discussing the chemical composition and chemical variation within zircons from the Monte Capanne pluton. Based on these data and other works (Dini et al. 2004 in Lithos 78:101–118, 2004) , it is inferred that mixing between metaluminous and peraluminous melts occurred early in the evolution of the Monte Capanne magma chamber. In particular, mixing was responsible for the development of the patchy-zoning texture in the zircon cores, which was associated with reactions between other accessory phases (including monazite, apatite, allanite), which we infer to have significantly affected the Th distribution in zircon. Zircons from the MC pluton displaying “homogeneous cores” have chemical affinities with zircons in the coeval Capraia volcanic system, consistent with the participation of a Capraia-like mantle end-member during mixing. Further zircon growth in the MC pluton produced the oscillatory zoning texture, which records both long-term (crystal fractionation) and transient (recharge with both silicic and mafic magmas) events in a hybrid magma chamber. It is inferred that Hf and the Th/U ratio cannot be used alone to infer magmatic processes due to their dependency on temperature, nor are they a diagnostic feature of xenocrystic grains. This study shows that zircon chemistry coupled with detailed textural analysis can provide a powerful tool to elucidate the complex evolution of a magma system.

description: Zusammen mit der Microservice-Bewegung werden immer häufiger synchrone Request-Response-Schnittstellen nach dem REST-Paradigma entwickelt, um Service-Landschaften zu integrieren. Die Einfachheit des Paradigmas verleitet viele Organisationen, nahezu die komplette Interprozesskommunikation ihres Ökosystems über diese Art von Schnittstelle abzuwickeln – nicht ohne Konsequenzen. Diese Arbeit entwickelt Ansätze, wie die Integrationsprobleme, die bei übermäßiger Verwendung von REST entstehen, mithilfe von Event-Driven Architecture gelöst werden können, ohne den Status quo dieser Organisationen außer Acht zu lassen. Dafür werden der gegenwärtige Zustand der Integrationsmuster und eingesetzten Infrastruktur von Event-Driven Architecture kritisiert und Kriterien erarbeitet, die pragmatische und zugängliche Integrationsansätze erfüllen müssen. Um die Einführungskosten gering zu halten, wird eine Middleware entwickelt, die in bestehende REST-Schnittstellen eingesetzt werden kann und auf Basis der API-Aufrufe Events generiert. Darauf aufbauend werden vier Integrationsmuster entwickelt, die eine schrittweise Transformation zu Event-Driven Microservices ermöglichen. Um die Zugänglichkeit der Eventing-Infrastruktur zu erhöhen, wird außerdem wird die Standardisierung der Event-Struktur durch die CloudEvents-Spezifikation vorgeschlagen. Um die Zugänglichkeit weiter zu erhöhen, erfolgt die Kommunikation der Services nicht direkt mit dem Event-Broker, sondern über Proxies, die die Events per HTTP annehmen oder ausspielen. Um die Transparenz über den Datenfluss im System zu wahren, werden alle Produzenten und Konsumenten werden mitsamt ihrer Events durch den Beschreibungsstandard AsyncAPI dokumentiert. Nach einer Validierung dieser Ansätze mithilfe eines Prototyps kommt diese Arbeit zu der Erkenntnis, dass der Einsatz der entwickelten Middleware für alle Organisationen sinnvoll ist, die bereits viele REST-Schnittstellen im Einsatz haben. Die Standardisierung der Event-Struktur und des Event-Protokolls mittels CloudEvents und HTTP-Proxies sowie die Dokumentation durch AsyncAPI empfiehlt sich auch unabhängig des Status quo für alle Organisationen, die Event-Driven Microservices entwickeln möchten.

description: Browser fingerprinting consists in collecting attributes from a web browser to build a browser fingerprint. In this work, we assess the adequacy of browser fingerprints as an authentication factor, on a dataset of 4,145,408 fingerprints composed of 216 attributes. It was collected throughout 6 months from a population of general browsers. We identify, formalize, and assess the properties for browser fingerprints to be usable and practical as an authentication factor. We notably evaluate their distinctiveness, their stability through time, their collection time, and their size in memory. We show that considering a large surface of 216 fingerprinting attributes leads to an unicity rate of 81% on a population of 1,989,365 browsers. Moreover, browser fingerprints are known to evolve, but we observe that between consecutive fingerprints, more than 90% of the attributes remain unchanged after nearly 6 months. Fingerprints are also affordable. On average, they weigh a dozen of kilobytes, and are collected in a few seconds. We conclude that browser fingerprints are a promising additional web authentication factor.

description: (ABRIDGED) We have applied the near-IR Barnes-Evans realization of the Baade-Wesselink method as calibrated by Fouque & Gieren (1997) to five metal-poor Cepheids with periods between 13 and 17 days in the Small Magellanic Cloud as well as to a sample of 34 Galactic Cepheids to determine the effect of metallicity on the period-luminosity (P-L) relation. For ten of the Galactic Cepheids we present new accurate and well sampled radial-velocity curves. The Baade-Wesselink analysis provides accurate individual distances and luminosities to the Cepheids in the two samples, allowing us to constrain directly, in a purely differential way, the metallicity effect on the Cepheid P-L relation. For the Galactic Cepheids we provide a new set of P-L relations which have zero-points in excellent agreement with astrometric and interferometric determinations. These relations can be used directly for the determination of distances to solar-metallicity samples of Cepheids in distant galaxies, circumventing any corrections for metallicity effects on the zero-point and slope of the P-L relation. We find evidence for both such metallicity effects in our data. Comparing our two samples of Cepheids at a mean period of about 15 days, we find a weak effect of metallicity on the luminosity similar to that adopted by the HST Key Project on the Extragalactic Distance Scale.

description: After nearly three decades of isolation from the world economy, Myanmar is moving forward with political and economic reforms. As a result of this political and economic transformation Myanmar has tremendous opportunities for growth. Although agriculture accounts for the largest share of employment in Myanmar, its contribution to GDP is small. Myanmar’s agriculture value chains are underdeveloped; smallholder capacity is low and investment in the agriculture sector has been limited. At the same time, Myanmar’s geographic position and climate make agriculture a potential driver for growth and development. In particular, Myanmar is well positioned to become a large exporter of rubber. Large parts of the high rainfall areas in eastern and southeastern Myanmar are well-suited for rubber cultivation. Following a gradual liberalization of the agriculture sector in the 1990s and a surge in rubber prices in international markets in the2000s, there was a surge in smallholder investment. Although yields remain low, they have risen substantially over the past two decades.

description: Tobin and Houthakker's work on consumer behavior under quantity rationing has been extended by many authors, especially through the use of duality theory. This paper uses duality theory to extend the work on demand theory under rationing to the case of producer behavior under quotas. These results permit estimation of otherwise unobservable market supply and demand structures. The structure of the farm economy operating under a tobacco quota system is estimated, and the theory is utilized to infer that the supply elasticity of tobacco would be about 7 .0 if the quotas were removed. Estimates such as this are not normally attainable without the theory outlined here, even though they are essential for the evaluation of policy changes.

description: The importance of effective and appropriate policies in achieving broader development objectives through agriculture is increasingly being recognized by national governments, development agencies, and supranational institutions. Despite increasing attention to improving the quality of agricultural policy discussions and decision-making, in many ways these efforts are proceeding in the absence of a systematic strategy for how to achieve this. This paper provides a practical guide for applied policy researchers and other stakeholders engaged in agricultural policy reform in developing countries. It draws on a case study from Zambia to provide a set of tools and strategies to improve the effectiveness of policy engagement. This guide consolidates years of practical experiences with agricultural policy dialogue and change garnered primarily through Michigan State University's collaborative research and policy programs in SubSaharan Africa.

description: A methodology is presented that permits simultaneous consideration of the economics of production and groundwater contamination hazard of pesticide use. An example is constructed for weed control in soybean (Glycine max) production at Clayton, North Carolina. A cost/groundwater hazard frontier is, developed that can be used to identify and illustrate the cost tradeoffs of selecting alternative weed control strategies that reduce the risk of adverse health effects from drinking contaminated groundwater. 1The methodology relies on models to estimate costs, crop yields, pest competition, and leaching.of pesticides; thus, its applicability depends on availability of local data and appropriately validated models for the site considered. The cost/groundwater hazard frontier provides an excellent decision aid to assist pesticide users in making cost-effective and environmentally favorable production decisions. I:t is also useful in evaluating policy or the value of new pest control technologies, as it indicates a farmer's ability to substitute alternatives for currently used practices.

description: An example is developed to show that the loose ideological definition that describes sustainable agriculture may mask conflicting objectives. A nebulous definition supports wider support but also leads to inefficient use of research and training resources. A popular goal, environmental quality, is defined in terms of measurable objectives: soil erosion, pesticide leaching, pesticide runoff, and excess nitrogen. Restrictions on these environmental pollutants had very different impacts on profits, and sometimes restricting one increased another. Greater success in improving the environment and in research accountability will be realized as supporters set priories for objectives. Economists can provide information that will help to set priories for these objectives.

description: The James Webb Space Telescope (JWST) will devote significant observing time to the study of exoplanets. It will not be serviceable as was the Hubble Space Telescope, and therefore the spacecraft/instruments will have a relatively limited life. It is important to get as much science as possible out of this limited observing time. We provide an analysis framework (including publicly released computational tools) that can be used to optimize lists of exoplanet targets for atmospheric characterization. Our tools take catalogs of planet detections, either simulated, or actual; categorize the targets by planet radius and equilibrium temperature; estimate planet masses; generate model spectra and simulated instrument spectra; perform a statistical analysis to determine if the instrument spectra can confirm an atmospheric detection; and finally, rank the targets within each category by observation time required. For a catalog of simulated Transiting Exoplanet Survey Satellite planet detections, we determine an optimal target ranking for the observing time available. Our results are generally consistent with other recent studies of JWST exoplanet target optimization. We show that assumptions about target planet atmospheric metallicity, instrument performance (especially the noise floor), and statistical detection threshold, can have a significant effect on target ranking. Over its full 10-year (fuel-limited) mission, JWST has the potential to increase the number of atmospheres characterized by transmission spectroscopy by an order of magnitude (from about 50 currently to between 400 and 500).
