description: A complete analysis of the electroweak precision observables is performed within a recently proposed minimal composite Higgs model, realized as a 5-dimensional warped compactification. In particular, we compute Z->bb and the one-loop correction to the rho parameter. We find that oblique data can be easily reproduced without a significant amount of tuning in the parameters of the model, while Z->bb imposes a stronger constraint. As a consequence of the latter, some of the new fermionic resonances must have mass around 4 TeV, which corresponds to an electroweak fine tuning of a few percent. Other resonances, such as Z', can be lighter in sizeable portions of the parameter space. We discuss in detail the origin of the Z->bb constraint and we suggest several possible avenues beyond the minimal model for weakening it.

description: We study the convergence rate to equilibrium for a family of Markov semigroups $\{\mathcal{P}_t^ε\}_{ε> 0}$ generated by a class of hypoelliptic stochastic differential equations on $\mathbb{R}^d$, including Galerkin truncations of the incompressible Navier-Stokes equations, Lorenz-96, and the shell model SABRA. In the regime of vanishing, balanced noise and dissipation, we obtain a sharp (in terms of scaling) quantitative estimate on the exponential convergence in terms of the small parameter $ε$. By scaling, this regime implies corresponding optimal results both for fixed dissipation and large noise limits or fixed noise and vanishing dissipation limits. As part of the proof, and of independent interest, we obtain uniform-in-$ε$ upper and lower bounds on the density of the stationary measure. Upper bounds are obtained by a hypoelliptic Moser iteration, the lower bounds by a de Giorgi-type iteration (both uniform in $ε$). The spectral gap estimate on the semigroup is obtained by a weak Poincaré inequality argument combined with quantitative hypoelliptic regularization of the time-dependent problem.

description: We have undertaken a long-term project, Planets in Stellar Clusters Extensive Search (PISCES), to search for transiting planets in open clusters. In this paper we present the results for NGC 2158, an intermediate age, populous cluster. We have monitored the cluster for over 260 hours, spread over 59 nights. We have detected one candidate transiting low luminosity object, with eclipse depth of 3.7% in the R-band. If the host star is a member of the cluster, the eclipse depth is consistent with a 1.7 R_J object. Cluster membership of the host is supported by its location on the cluster main sequence (MS) and its close proximity to the cluster center (2'). We have discovered two other stars exhibiting low-amplitude (4-5%) transits, V64 and V70, but they are most likely blends or field stars. Given the photometric precision and temporal coverage of our observations, and current best estimates for the frequency and radii of short-period planets, the expected number of detectable transiting planets in our sample is 0.13. We have observed four outbursts for the candidate cataclysmic variable V57. We have discovered 40 new variable stars in the cluster, bringing the total number of identified variables to 97, and present for them high precision light curves, spanning 13 months.

description: SABRE (Signal Amplification By Reversible Exchange) has become a widely used method for hyper-polarizing nuclear spins, thereby enhancing their Nuclear Magnetic Resonance (NMR) signals by orders of magnitude. In SABRE experiments, non-equilibrium spin order is transferred from parahydrogen to a substrate in a transient organometallic complex. Applicability of SABRE is expanded by the methodology of SABRE-relay, in which polarization can be relayed to a second substrate either by direct chemical exchange of hyperpolarized nuclei or by polarization transfer between two substrates in a second organometallic complex. To understand the mechanism of the polarization transfer and study the transfer efficiency, we propose a theoretical approach to SABRE-relay, which can treat both spin dynamics and chemical kinetics as well as the interplay between them. The approach is based on a set of equations for the spin density matrices of the spin systems involved (i.e., SABRE substrates and complexes), which can be solved numerically. Using this method, we perform a detailed study of polarization formation and analyse in detail the dependence of attainable polarization level on various chemical kinetic and spin dynamic parameters. We foresee applications of the present approach for optimizing SABRE-relay experiments with the ultimate goal of achieving maximal NMR signal enhancements for substrates of interest.

description: We use the second Gaia data release in combination with the catalog of Sanders & Das (2018) to dissect the Milky Way disc in phase-space and relative ages. We confirm and report the existence of multiple velocity moving groups at low azimuthal velocities and angular momenta, below Arcturus, regularly separated by $\sim~18-20\,\rm{km s^{-1}}$ in azimuthal velocity. Such features were predicted to exist more than ten years ago from the reaction of the Milky Way to a perturbation in the disc undergoing phase-mixing. These structures appear slightly younger than their phase-space surroundings, arguing against an extra-galactic origin. We also identify in relative age many of the classical ridges in the plane of azimuthal velocity vs. Galactocentric radius, traditionally associated with resonance features. These ridges are also younger than their phase-space surroundings in accordance with predictions from recent state-of-the-art cosmological hydrodynamical simulations of Milky Way-like galaxies. We study the response of dynamically young and old stellar disc populations to resonances from an analytic model of a large bar, which, remarkably, qualitatively reproduces the trends seen in the data. Our results re-inforce the idea that the Galactic disc is currently being shaped by both internal and external perturbations, and that, while absolute isochrone ages have to be taken with great care, exploring the dynamical structure of the disc in stellar ages, especially with future asteroseismic data, will provide much stronger constraints than metallicity/abundance trends alone.

description: The thermodynamic properties of S>=1 ferromagnetic chains with an easy-axis single-ion anisotropy are investigated at arbitrary temperatures by both a Green-function approach, based on a decoupling of three-spin operator products, and by exact diagonalizations of chains with up to N=12 sites using periodic boundary conditions. A good agreement between the results of both approaches is found. For the S=1 chain, the temperature dependence of the specific heat reveals two maxima, if the ratio of the anisotropy energy D and the exchange energy J exceeds a characteristic value, D/J >7.4, and only one maximum for D/J <7.4. This is in contrast to previous exact diagonalization data for comparably small chains (N <= 7) using open boundary conditions. Comparing the theory with experiments on di-bromo Ni complexes the fit to the specific heat yields concrete values for D and J which are used to make predictions for the temperature dependences of the spin-wave spectrum, the correlation length, and the transverse magnetic susceptibility.

description: The parameters of the nuclear liquid drop model, such as the volume, surface, symmetry, and curvature constants, as well as bulk radii, are extracted from the non-relativistic and relativistic energy density functionals used in microscopic calculations for finite nuclei. The microscopic liquid drop energy, obtained self-consistently for a large sample of finite, spherical nuclei, has been expanded in terms of powers of A^{-1/3} (or inverse nuclear radius) and the isospin excess (or neutron-to-proton asymmetry). In order to perform a reliable extrapolation in the inverse radius, the calculations have been carried out for nuclei with huge numbers of nucleons, of the order of 10^6. The Coulomb interaction has been ignored to be able to approach nuclei of arbitrary sizes and to avoid radial instabilities characteristic of systems with very large atomic numbers. The main contribution to the fluctuating part of the binding energy has been removed using the Green's function method to calculate the shell correction. The limitations of applying the leptodermous expansion to actual nuclei are discussed. While the leading terms in the macroscopic energy expansion can be extracted very precisely, the higher-order, isospin-dependent terms are prone to large uncertainties due to finite-size effects.

description: Stamens with monocolpate Clavatipollenites- type pollen sp. 4
Text-fig. 13a–d
Description and remarks. The material comprises a fragment of a staminate structure with more than ten closely packed stamens that have in situ Clavatipollenitestype pollen. There are no well-developed filaments. The shape of the fragment indicates that the anthers were sessile or almost sessile and that the stamens were originally borne in whorls in a multistaminate inflorescence (Text-fig. 13a). The anthers are strongly compressed, obovate in outline, about 0.5 mm long and 0.2 mm broad. Pollen is monoaperturate with a poorly delimited aperture (Text-fig. 13b, c). The grains are about 14–17 µm in diameter. The exine is semitectatereticulate with a homobrochate reticulum (Text-fig. 13b–d). Lumina are irregular, up to about 1 µm in diameter. Muri are narrow, about 0.3 µm wide ornamented with minute verrucae arranged in one to two rows. Columellae are long, about 0.7 µm, and widely spaced (Text-fig. 13d). Orbicules were not observed.
Affinity and other occurrences. See comments on “Stamens with monocolpate Clavatipollenitestype pollen sp. 1” above. The pollen is closely similar to dispersed fossil grains assigned to the extinct genus Clavatipollenites, as well as pollen of extant Ascarina. The stamens are similar to those in the staminate inflorescences of Proencistemon portugallicus and Proencistemon sp. from Catefica (above) in being arranged in dense whorls and having sessile or almost sessile anthers. However, pollen in situ within stamens of Proencistemon differs in having a trichotomocolpate aperture, and stamens of Proencistemon are longer than those of the staminate structure described here. The estimated number of stamens per whorl is also fewer than in Proencistemon.

description: Long-baseline interferometric observations obtained with the Navy Prototype Optical Interferometer of the H-alpha-emitting envelopes of the Be stars eta Tauri and beta Canis Minoris are presented. For compatibility with the previously published interferometric results in the literature of other Be stars, circularly symmetric and elliptical Gaussian models were fitted to the calibrated H-alpha observations. The models are sufficient in characterizing the angular distribution of the H-alpha-emitting circumstellar material associated with these Be stars. To study the correlations between the various model parameters and the stellar properties, the model parameters for eta Tau and beta CMi were combined with data for other Be stars from the literature. After accounting for the different distances to the sources and stellar continuum flux levels, it was possible to study the relationship between the net H-alpha emission and the physical extent of the H-alpha-emitting circumstellar region. A clear dependence of the net H-alpha emission on the linear size of the emitting region is demonstrated and these results are consistent with an optically thick line emission that is directly proportional to the effective area of the emitting disk. Within the small sample of stars considered in this analysis, no clear dependence on the spectral type or stellar rotation is found, although the results do suggest that hotter stars might have more extended H-alpha-emitting regions.

description: We compute the differential rotation of main sequence stars of the spectral types F, G, K, and M by solving the equation of motion and the equation of convective heat transport in a mean-field formulation. For each spectral type the rotation rate is varied to study the dependence of the surface shear on this parameter. The resulting rotation patterns are all solar-type. The horizontal shear turns out to depend strongly on the effective temperature and only weakly on the rotation rate. The meridional flow depends more strongly on the rotation rate and has different directions in the cases of very slow and very fast rotation, respectively.

description: WTO trade negotiations on market access follow the MFN treatment. However, an increasing share of trade falls under preferential regimes. For agriculture, trade liberalization analyses have showed that the impact on developing countries (DC) is not uniform, partly from omitting preferences. In this paper, we examine whether preference-recipient DC benefit more from across the board tariff cuts than from preferences. We employ a global CGE model with detailed preference-inclusive tariff database to examine the differential impact of trade liberalization on DC subject to preferences versus MFN-based market access. We focus on the European Union- the world largest preferences provider- and run two experiments of tariff cuts by the EU: a 50% across-the-board MFN tariff cut on agricultural products with or without comparable preferential tariff cuts. Results show that EU preferences confer a market access advantage for beneficiary countries, especially the Least Developed and ACP countries, which is eroded under MFN tariff cuts. A combination of across-the-board MFN and preferential tariff cuts (to preserve margins of preference) enable some but not all preferential partners to preserve or increase its trade with the EU. Moreover, the composition of trade changes and the magnitude of trade loss will vary between partners and products and depends on the specifics of the preferential regime. As a follow up to the present study, we will further examine trade and welfare impacts in the case of select key agricultural products subject to tariff preferences within preferential quotas or tariff-rate quotas.

description: We systematically study supersymmetric embeddings of D-brane probes of different dimensionality in the AdS_5xY^{p,q} background of type IIB string theory. The main technique employed is the kappa symmetry of the probe's worldvolume theory. In the case of D3-branes, we recover the known three-cycles dual to the dibaryonic operators of the gauge theory and we also find a new family of supersymmetric embeddings. The BPS fluctuations of dibaryons are analyzed and shown to match the gauge theory results. Supersymmetric configurations of D5-branes, representing domain walls, and of spacetime filling D7-branes (which can be used to add flavor) are also found. We also study the baryon vertex and some other embeddings which break supersymmetry but are nevertheless stable.

description: Land markets, including land sales and short-term land rentals, have an important role to play for efficient and sustainable land management and agricultural development, especially where markets for other factors of production are imperfect or missing. This study utilises data from the highlands of Ethiopia, Kenya and Uganda to examine the impact of land markets on various types of land investment and management practices, crop yield, and land quality. The results highlight the relative long-term versus short-term return to different types of investment and practices, where those with longer-term benefits such as trees, manuring, and composting are preferred on more tenure-secure plots, while those with immediate or season-to-season benefits such as drainage structures or chemical fertilizers are preferred on rented plots. The impact on agricultural productivity is mixed and context specific. Regarding land quality outcomes, there is reason to believe that plots traded on short-term markets in Kenya and Uganda tend to be of inferior quality, supporting the hypothesis of movement of land from households to those with higher capital/land ratios.

description: We report the realization of coupling-independent, robust wireless sensing of fully-passive resistive sensors. PT-symmetric operation obviates sweeping, permitting real-time, single-point sensing. Self-oscillation is achieved through a fast-settling nonlinearity whose voltage amplitude is proportional to the sensor's resistance. These advances markedly simplify the reader. A dual time-scale theoretical framework generalizes system analysis to arbitrary operating conditions and a correction strategy reduces errors due to detuning from PT-symmetric conditions by an order of magnitude.

description: The details of ignition of Type Ia supernovae remain fuzzy, despite the importance of this input for any large-scale model of the final explosion. Here, we begin a process of understanding the ignition of these hotspots by examining the burning of one zone of material, and then investigate the ignition of a detonation due to rapid heating at single point. We numerically measure the ignition delay time for onset of burning in mixtures of degenerate material and provide fitting formula for conditions of relevance in the Type Ia problem. Using the neon abundance as a proxy for the white dwarf metallicity, we then find that ignition times can decrease by ~20% with addition of even 5% of neon by mass. When temperature fluctuations that successfully kindle a region are very rare, such a reduction in ignition time can increase the probability of ignition by orders of magnitude. If the neon comes largely at the expense of carbon, a similar increase in the ignition time can occur. We then consider the ignition of a detonation by an explosive energy input in one localized zone, eg a Sedov blast wave leading to a shock-ignited detonation. Building on previous work on curved detonations, we find that surprisingly large inputs of energy are required to successfully launch a detonation, leading to required matchheads of ~4500 detonation thicknesses - tens of centimeters to hundreds of meters - which is orders of magnitude larger than naive considerations might suggest. This is a very difficult constraint to meet for some pictures of a deflagration-to-detonation transition, such as a Zel'dovich gradient mechanism ignition in the distributed burning regime.

An empowered voice? : an assessment of the participatory process conducted to draft a proposal for the establishment of the Inkomati Catchment Management Agency, Mpumalanga, South Africa

description: Public participation is becoming increasingly important in the management of natural resources. South Africa has recognised the link between environmental management and public participation through the passing of the National Water Act (Act 36 of 1998), which legalised the establishment of 19 Catchment Management Agencies (CMA's). One of the objectives of these CMA's is to delegate responsibilities at the catchment level so that interested parties can participate. Social equity in decision-making is therefore seen as an important aspect of sustainable catchment management. This thesis focuses on social equity in decision-making, given South Africa's lack of experience in this regard. The objective of this thesis is to assess the public participation process conducted in 2000 to draft a proposal for the establishment of the Inkomati Catchment Management Agency, the first CMA in South Africa. The framework for the assessment was based on the literature of procedural justice and empowerment. The present research elucidates the context in which the participatory process was conducted, and assesses the participatory process with respect to the empowerment of stakeholders. The research methodology followed a qualitative research paradigm. Information was triangulated between 62 semi-structured interviews with stakeholders who were involved in the process, observations in the field, and documents relating to the case. The findings illustrate that the public participation process was not completely procedurally just nor was it completely successful in empowering stakeholders to make informed decisions. To assist in ensuring more social equity in decision-making, multi-dimensional learning, encompassing technical, ecological, and social knowledge of water management is recommended as a process goal. To achieve this the following mechanisms were identified as important: 1) Sufficient finances and external support; 2) Effective representative structures; 3) Creative and diverse opportunities for interaction; 4) Adequate opportunities to allow stakeholders to have an influence; 5) Transparent, dedicated, and empowering facilitators; and 6) Adequate information and avoidance of misinformation. This research offers a unique perspective on a participatory process that forms the building block for the establishment of sustainable Catchment Management in South Africa.

description: As concern regarding the environmental and economic impacts of non-native invasive species (NIS) grows, governments are devoting greater resources to NIS management. Yet, management agencies continue to face limited resources as they handle an increasing number of diverse nonindigenous species. Substantial damages from certain invaders have fueled the widely-accepted perspective that prevention is the optimal management strategy. Unfortunately, it is not always possible due to the highly uncertain nature of potentially invasive species coupled with the need to manage existing invasive species. Thus, agencies must constantly detect and control species after they have arrived. This detection stage, and its relationship to the management activities, is often overlooked by existing literature which focuses on the prevention and control stages. This paper analyzes the optimal management strategies for government agencies after the species has been introduced. Using a two-stage stochastic dynamic model, we capture the stochastic nature of successful detection of a species. The probability of detection depends on the interaction between the chosen search intensity and the species' population density. While high levels of search and control are optimal for invasive species with high damages, such as the Emerald Ash Borer, the optimal management levels are often much lower for less invasive or less damaging species. The paper also examines the effect of uncertainty in various parameters to assess the optimal resource allocation between management strategies.

description: The transition process in central and eastern Europe (CEE) had a profound effect on how individuals interact. Economic and social institutions have changed, requiring an adaptation process by individuals in the move toward a market economy. How each individual accesses, manipulates and uses their networks will determine the use of their social capital. Within CEE, there is a presumption of low levels of social capital. This paper was written as a conceptual framework for a research project entitled 'Integrated Development of Agricultural and Rural Institutions' (IDARI) in CEE countries. The paper exposes the emergence and maintenance of cooperative behaviour in light of rural restructuring and institutional change in CEE. A link exists between social capital formation and cooperation amongst individuals, as both concepts imply social interaction and the formation of trust. This paper questions the rationale of applying the contested 'western' concept of social capital to CEE countries. Social networks and use of those networks (social capital) is becoming more important in light of accession to the EU, particularly when opportunities within and access to rural and regional development programmes are dependent on existing networks. Social capital is seen as a dynamic entity, a form of institutional change, which leads to innovation in governance. Thus social capital provides a powerful explanatory tool for processes of institutional change.

description: We have conducted a systematic search for stellar disk truncations in disk-like galaxies at intermediate redshift (z<1.1) using the Hubble Ultra Deep Field (UDF) data. We use the position of the truncation as a direct estimator of the size of the stellar disk. After accounting for the surface brightness evolution of the galaxies, our results suggest that the radial position of the truncations has increased with cosmic time by ~1-3 kpc in the last ~8 Gyr. This result indicates a small to moderate (~25%) inside-out growth of the disk galaxies since z~1.

description: Maize is an important staple in Mozambique. It is also a dominant crop produced by smallholder farmers. However, the actual maize yields, currently estimated at 1.4 tons/ha, fall short of potential yields of 5-6.5 tons/ha. With population growth rate increasingly exceeding agricultural (and maize) productivity growth rate, the government of Mozambique faces a serious problem of food insecurity and poverty alleviation. This study examines cost inefficiency among smallholder maize farmers in Mozambique, and the impact of improved maize seed adoption on cost efficiency. A Translog functional form is used to estimate the frontier cost function. A cost-inefficiency function is used to examine the factors that determine cost inefficiency among farmers. Econometric techniques to control for self-selection bias resulting from endogeneity of the adoption variable are used.

description: The geometry of the elementary charge is studied in the framework of the concept of space considered as a tessellation lattice ('tessellattice'), which has recently been developed by M. Bounias and the author. The descriptive-geometric sense of the electric and magnetic fields and their carriers - photons - is analyzed. The notion of the scalar and vector potentials of a charged particle and their behavior at the motion of the particle along a path is investigated in detail. Based on the potentials, the Lagrangian leading to the Maxwell equations is constructed. The distinctive properties of the inerton and the photon - two basic elementary excitations, or quasi-particles of the space tessellattice - are discussed. Summarizing, we may say that the work suggests the detailed interpretation of the Maxwell equations in terms of the submicroscopic approach to Nature.

description: The analytical expressions for both diagonal and off-diagonal ac and dc conductivities of graphene placed in an external magnetic field are derived. These conductivities exhibit rather unusual behavior as functions of frequency, chemical potential and applied field which is caused by the fact that the quasiparticle excitations in graphene are Dirac-like. One of the most striking effects observed in graphene is the odd integer quantum Hall effect. We argue that it is caused by the anomalous properties of the Dirac quasiparticles from the lowest Landau level. Other quantities such as Hall angle and Nernst signal also exhibit rather unusual behavior, in particular when there is an excitonic gap in the spectrum of the Dirac quasiparticle excitations.

description: 就職活動において重要な要素の 1 つに面接が存在する. 面接では, 視線や仕草, 表情, 声の大きさ, 抑揚の有無, 話し方, 話す内容など様々な観点から就職志願者を 精査している. しかし, 多くの人は面接で自分の実力を最大限発揮できないと考え る. また, 自分の実力を発揮するために, 面接の練習を行うこともしばしばあるが, 練習を行う上で, 人に見られることに恥ずかしさや煩わしさを感じたり, 1 人で練 習するにしても何が悪いのか, また何を直したらいいのかわからないと感じる人は 多いと考える. 既存研究や既存システムには実際にプレゼンテーションを行い改善を促すシス テムや, 実際に面接官が目の前にいるように見せるためにバーチャルリアリティー を用いて, 自己 PR や質疑を行い適切な職種を提示してくれるシステムなどが存在 する. しかし, これらのシステムは, 自分が主張したい文や箇所がきちんと強調で きているかわからないというのが現状である. また, 表情の取得も行っていない. 本研究では, 就職活動における面接での自己 PR を想定した文章を読んでもらい, 強調すべき箇所がきちんと強調できているのか, 適切な表情になっているのか, 画 像処理や音声処理を用いて見本となるデータとの比較により 5 段階でフィードバッ クを行うシステムの開発を行う. これにより, ユーザーが強調すべき箇所を強調し ている話し方になることを期待する. 評価実験では, 我々自身で行う実験 1 と, システムの評価が適切か確かめるため の実験 2 を行った. 実験 1 では, 面接時における自己 PR に対して, 明らかに適し ていない表情や話し方をした場合と, 適切な表情や話し方をした場合において適切に評価されるかを確かめるために行った. その結果, 音声に関しては, 適切な抑揚 をつけたときは最大評価の 4, 棒読みになると低い評価である 2 という適切な評価 が表示された. しかし, 視線と顔の動きに関して, 見本となるデータが大きく動い ているものと, あまり動いていないものが存在したため, 大袈裟に顔などを動かし ても最大評価の 4 になってしまうこととなってしまった. 実験 2 では, システムの 評価が適切なのかを確かめるために, 実際に 5 人のユーザーにシステムを使用して もらい, その様子を録画した. 録画した映像をシステムを使用してもらった人とは 別の人に見てもらい, システムと同様の評価項目で評価してもらった. その結果, システムの評価結果と, 人による評価結果に全体の抑揚では相関係数が 0.68, 強調 でも相関係数 0.42 と中程度の相関が表れた. そのため, 適切なフィードバックを行 うことが出来る. しかし, 話す速さや画像に関する部分については相関係数が 0.2 未満と相関がないという結果になった. そのため, 表情や, 顔の動きなどは適切に フィードバックができないとなった. 今後の課題として, 3 つ挙げられる. 1 つ目は見本となるデータが適切かどうかで ある点である. 今回は見本となるデータに大学生 2 名を使用したが, その適切さに ついては検証していない. そのため, 明らかに適していない話し方をしない限りは 悪くない評価が表示されることとなってしまった. 2 つ目は結果表示に時間がかか る点である. 画像処理に関して画像処理の過程でタイムラグが発生し, 結果の表示 に時間がかかることがわかったので改善する必要がある. 3 つ目は, 相関がなかっ た評価項目について必要か, 不必要なのか見当する必要がある点である. 今回, 全 体の抑揚, 強調についてはそれぞれ中程度の相関があるとなったが, 他の項目につ いては相関係数が 0.2 未満と相関がないという結果になってしまった. 原因は様々 あると考えられるが, 特に画像に関しては顔の動きについて見当する必要があると 考える. 人が頷く時, それがシステムでは動いたと判定されマイナスの評価になっ てしまったが, 人が評価するとそれが説得力のある話し方に見えることもある. こ のような差を検証していく必要がある
