description: Two different computational approaches to the magnetorotational instability (MRI) are pursued: the shearing box approach which is suited for local simulations and the embedding box approach whereby a Taylor Couette flow is embedded in a box so that numerical problems with the coordinate singularity are avoided. New shearing box simulations are presented and differences between regular and hyperviscosity are discussed. Preliminary simulations of spherical nonlinear Taylor Couette flow in an embedding box are presented and the effects of an axial field on the background flow are studied.

description: Современное общество, вступившее в эпоху глобализации, остро нуждается в осмыслении коммуникативных процессов, происходящих в нем. С одной стороны, необходимо исследовать тенденции, которые способствуют объединению цивилизаций, народов и культур, с другой стороны, нуждаются в осмыслении факты, обусловливающие сохранение национальной идентичности культур в условиях их тесного взаимодействия. В обществе, культуре и языке в равной мере наблюдаются две тенденции - к обособлению и унификации - и обе они в равной степени актуальны для исследования. Вданной статье рассматриваются к проблеме трактовки понятия «культуроведческая компетенция» в методике русского языка.

description: The paper extends the household hedonic model, as a non-market valuation tool, by estimating a supply function for variety attributes of a subsistence crop in a developing country. The model is applied to bananas in Uganda, making use of disaggregated data on variety-specific farm-gate banana bunch prices and attributes. The hedonic analysis is applied at the farm-gate, the first link in the market chain, while accounting for the semi-subsistence nature of banana producing households. Within the framework of the agricultural household, where consumption and production decisions are non-separable, prices reflect the implicit marginal valuation of both consumption and production attributes jointly. The paper is motivated by the need to quantify the value of banana attributes in light of targeted efforts for variety improvement. Whether variety improvement will pay-off at the market level requires a more detailed examination of the relative worth of banana attributes within the structure of consumer preferences and production technologies related to bananas in Uganda. By revealing important price-attribute relationships, the findings provide guidance for future crop improvement efforts and diversification choices, while taking into account implicit market signals for output characteristics.

description: This paper analyzes the current and proposed biosafety systems in Kenya, Tanzania, and Uganda using a set of components and characteristics common to functional and protective biosafety regulatory systems. It also assesses how those systems take into account the major international legal obligations that relate to biosafety, such the Cartagena Biosafety Protocol. The paper identifies certain areas in each country’s biosafety regulatory systems where further development and clarification would improve the biosafety system, making it more functional and protective. Those areas include: (1) the addition of procedures to ensure the food safety of genetically engineered organisms; (2) the inclusion of the standard and criteria for making an approval decision; (3) the differentiation of regulatory procedures based on the relative risk of the organism; and (4) an explanation of how socio-economic considerations will be defined and assessed. Finally, the paper discusses possible ways the three countries can coordinate and harmonize their national biosafety regulatory systems so they are efficient, effective and make the best use of limited scientific and legal capacity.

Maternal leukocyte CD markers, apoptosis and band forms in preeclampsia
Creators: name: Fuchisawa, Akiko
Publisher: name: University of British Columbia
Year: 2009

description: INTRODUCTION: Preeclampsia is a pregnancy-specific condition, and it still remains one of the most common causes of maternal mortality in the developed world. Although the exact cause of preeclampsia has not been identified, it is most widely accepted that preeclampsia results from incomplete placentation. Interestingly, normotensive intrauterine growth restriction also shows the same defect of placentation. In preeclampsia, the maternal syndrome develops from a number of alternative pathways leading to uteroplacental mismatch and, consequently, the release of endothelium-activating factors. This research is focused on neutrophil activation and the hypothesis for this research was that maternal neutrophils and monocytes are inappropriately activated in preeclampsia but not in normotensive intrauterine growth restriction. METHODS: This was a prospective controlled cohort study in a tertiary center. Subjects consisted of cases: women with early-onset preeclampsia (<34+0wk; EOPET), late-onset preeclampsia (≧34+0wk; LOPET), normotensive intrauterine growth restriction and controls: normal pregnancy controls (NPC) and non-pregnant controls (non-preg). Peripheral blood leukocytes were analyzed immediately after phlebotomy for CD11b, CD18, CD14 and band forms (marrow production). Neutrophils were cultured for 18-24h and apoptosis was assessed by Annexin V binding and hypodiploid PI. All analyses were by flow cytometry. Kruskal Wallis, Mann Whitney U and Dunn's post test were used for statistical analysis (significance at p<0.05). RESULTS: CD11b/CD18 monocyte expression was increased in pregnancy (all groups). CD18 expression was reduced on preeclampsia lymphocytes. CD14 expression was reduced on preeclampsia granulocytes. Gestational age-dependent decrease was noted for apoptosis in normal pregnancy. Band forms were increased in all pregnancy groups, with no difference seen between normal and abnormal pregnancy. CONCLUSIONS: Normal pregnancy is a state of Th1-to-Th2 switch. In preeclampsia, some findings noted by ourselves and others were not reproduced, probably due to steroid effects. Decreased CD18 on preeclampsia lymphocytes implies excess Th1 activity in preeclampsia. Preeclampsia granulocytes shed CD14, probably in response to prior activation. There was a gestational age effect on neutrophil apoptosis, as previously noted. However, neutrophil apoptosis was not inappropriately delayed in preeclampsia, probably due to steroid effects. Marrow production of neutrophils is similarly increased in all pregnancy groups.

description: Target search by active agents in rugged energy landscapes has remained a challenge because standard enhanced sampling methods do not apply to irreversible dynamics. We overcome this non-equilibrium rare-event problem by developing an algorithm generalizing transition-path sampling to active Brownian dynamics. This method is exemplified and benchmarked for a paradigmatic two-dimensional potential with a high barrier. We find that even in such a simple landscape the structure and kinetics of the ensemble of transition paths change drastically in the presence of activity. Indeed, active Brownian particles reach the target more frequently than passive Brownian particles, following longer and counterintuitive search patterns.

description: We present results of a new deep 1.1 mm survey using Bolocam, a millimeter-wavelength bolometer array camera designed for mapping large fields at fast scan rates, without chopping. A map, galaxy candidate list, and derived number counts are presented. This survey encompasses 324 arcmin^2 to an rms noise level (filtered for point sources) of 1.4 mJy/beam and includes the entire regions surveyed by the published 8 mJy 850 micron JCMT SCUBA and 1.2 mm IRAM MAMBO surveys. We reduced the data using a custom software pipeline to remove correlated sky and instrument noise via a principal component analysis. Extensive simulations and jackknife tests were performed to confirm the robustness of our source candidates and estimate the effects of false detections, bias, and completeness. In total, 17 source candidates were detected at a significance > 3.0 sigma, with six expected false detections. Nine candidates are new detections, while eight candidates have coincident SCUBA 850 micron and/or MAMBO 1.2 mm detections. From our observed number counts, we estimate the underlying differential number count distribution of submillimeter galaxies and find it to be in general agreement with previous surveys. Modeling the spectral energy distributions of these submillimeter galaxies after observations of dusty nearby galaxies suggests extreme luminosities of L = 1.0-1.6 x 10^13 L_solar and, if powered by star formation, star formation rates of 500-800 M_solar/yr.

description: After reviewing trends in the production and marketing of fresh produce for the domestic market in Kenya since 1997, this paper presents detailed information on the structure of the flow of this produce from rural areas to wholesale markets in Nairobi and from those wholesale markets to assorted retail markets. Market shares are estimated by product for geographic areas supplying Nairobi, and for each important wholesale and retail market in the city. It is found that horticultural production for the domestic market is keeping up with rural population growth but not with the much faster urban population growth. The urban wholesaling and retailing system has decentralized dramatically and with little planning over the past two decades in response to lack of investment in public market places. In the current system, all participants are subjected to high costs and poor quality, and many traders, especially but not only those in kiosks, are subject to theft and even bodily injury. Collaborative planning for new investment between city officials and farmer- and trader organizations is badly needed; positive signs of movement in this direction include a more constructive approach to kiosks and joint public/private planning for a new wholesale market outside Nairobi. As new approaches to wholesaling and retailing are considered in response to Vision 2030, the continuing importance of existing market places means that complementary improvements in these markets, at the same time that investments in new markets are being made, will have major positive effects on farmers and consumers.
Scaling Invariance in Spectra of Complex Networks: A Diffusion Factorial Moment Approach

description: A new method called diffusion factorial moment (DFM) is used to obtain scaling features embedded in spectra of complex networks. For an Erdos-Renyi network with connecting probability $p_{ER} < \frac{1}{N}$, the scaling parameter is $δ= 0.51$, while for $p_{ER} \ge \frac{1}{N}$ the scaling parameter deviates from it significantly. For WS small-world networks, in the special region $p_r \in [0.05,0.2]$, typical scale invariance is found. For GRN networks, in the range of $θ\in[0.33,049]$, we have $δ=0.6\pm 0.1$. And the value of $δ$ oscillates around $δ=0.6$ abruptly. In the range of $θ\in[0.54,1]$, we have basically $δ>0.7$. Scale invariance is one of the common features of the three kinds of networks, which can be employed as a global measurement of complex networks in a unified way.

description: This paper examines the effects of tenure on tree management at a community level. First, several important conceptual issues arising from this particular meso-level focus are discussed. Second, a description of the key tenure and tree management issues in Uganda and Malawi is presented. In each case, data representing changes in land use and tree cover between the 1960–70s and 1990s are analyzed. In both countries, there has been significant conversion of land from woodlands to agriculture. Tree cover has been more or less maintained over time in Uganda but has decreased in Malawi. Lastly, the paper explores the relationships between tenure and tree management using econometric techniques. Tenure is found to be linked to land-use and tree-cover change in both countries, though it is not necessarily the most important factor (e.g., population pressure is the key driving force for land-use change). In Uganda, conversion of land was more rapid under the customary tenure system and tree cover on nonagricultural land better maintained under the mailo system. In Malawi there was more rapid land-use conversion and tree cover depletion where there were more changes to traditional tenure systems taking place.

description: The adoption of intensified cattle-feeding techniques by smallholders in Sub-Saharan Africa has been slower than anticipated. This study seeks to better define and understand the role of local collective action in conditioning the strategies that smallholders choose to intensify their cattle-feeding techniques. Collective action was analyzed as a determinant of the transaction costs of accessing feed for these techniques. An in-depth case-study method was used in a single peri-urban village that was at a low but increasing level of intensification of land use. The research found that cattle-keepers were intensifying their cattle-feeding techniques, but in a much more marginal, step-wise fashion than anticipated. The process of intensification involved changes in transaction costs, which were born differently by smallholders depending on their sources of wealth and personal networks. Whereas previous studies have found wealth to be a key factor conditioning the adoptability of new techniques, this study shows that personal networks can be used in some cases as a substitute for wealth.

I present explicitly the first nonlocal symmetry flow in each of the two hierarchies of this system. An invariant solution of $CMA$ with respect to these nonlocal symmetries is constructed which, being a noninvariant solution in the usual sense, does not undergo symmetry reduction in the number of independent variables. I also construct the corresponding 4-dimensional anti-self-dual (ASD) Ricci-flat metric with either Euclidean or neutral signature. It admits no Killing vectors which is one of characteristic features of the famous gravitational instanton $K3$. For the metric with the Euclidean signature, relevant for gravitational instantons, I explicitly calculate the Levi-Civita connection 1-forms and the Riemann curvature tensor.

description: Lead-based halide perovskites have emerged as a most prominent candidate for emerging opto-electronic applications. In this talk we will briefly showcase recent efforts towards designing new Pb-free semiconductors that are alternatives to traditional halide perovskites, for which computational approaches from first-principles have been extensively successful and revealed a series of new compounds within the so-called halide double perovskites family and vacancy ordered perovskites. Among these, Cs2BiAgBr6 has the narrower indirect band gap of 1.9 eV, [1] and Cs2InAgCl6 is the only direct band gap semiconductor, yet with a large gap of 3.3 eV. [2] All of them exhibit low carrier effective masses and consequently, are prominent candidates for a range of opto-electronic applications such as photovoltaics, light-emitting devices, sensors, and photo-catalysts. [3] We will specifically outline the computational ab initio design strategy that led to the synthesis of these compounds, and particularly focus on the insights we can get from first-principles calculations in order to facilitate the synthesis, improve their opto-electronic properties and the in-silico identification of compounds with properties that are similar to the lead-halide perovskites. The newly developed concept of analogs will lead us to identify a new oxide double perovskite semiconductor, Ba2AgIO6, which exhibits an electronic band structure remarkably similar to that of our recently discovered halide double perovskite Cs2AgInCl6, but with a band gap in the visible range at 1.9 eV. [4] In the final part of our talk, we will employ this strategy to explore the phase space of vacancy-ordered double perovskite and discuss the case of Zr-based compounds as stable alternates to Cs2TiX4 with X=Br,I, which exhibit lighter charge carrier effective masses.[5] This DROP-IT project has received funding from the European Union’s Horizon 2020 research and innovation Program under the grant agreement No 862656.

description: The $ΔΔ$ dibaryon resonance $d^\ast (2380)$ with $(J^P, I)=(3^+, 0)$ is studied theoretically on the basis of the 3-flavor lattice QCD simulation with heavy pion masses ($m_π=679, 841$ and $1018$ MeV). By using the HAL QCD method, the central $Δ$-$Δ$ potential in the ${}^7S_3$ channel is obtained from the lattice data with the lattice spacing $a\simeq 0.121$ fm and the lattice size $L\simeq 3.87$ fm. The resultant potential shows a strong short-range attraction, so that a quasi-bound state corresponding to $d^\ast (2380)$ is formed with the binding energy $25$-$40$ MeV below the $ΔΔ$ threshold for the heavy pion masses. The tensor part of the transition potential from $ΔΔ$ to $NN$ is also extracted to investigate the coupling strength between the $S$-wave $ΔΔ$ system with $J^P=3^+$ and the $D$-wave $NN$ system. Although the transition potential is strong at short distances, the decay width of $d^\ast (2380)$ to $NN$ in the $D$-wave is kinematically suppressed, which justifies our single-channel analysis at the range of the pion mass explored in this study.

We examine how misophonia becomes a popular diagnosis, how experts and lay people refer to each other, and what resistance they face in this process. We understand the development of the medical category as »making up people«: as the development of a group of affected persons who identify closely with the diagnosis and vigorously fight for its recognition as an illness.

description: Three closely related stumbling blocks of solar mean field dynamo theory are discussed: how dominant are the small scale fields, how is the alpha effect quenched, and whether magnetic and current helicity fluxes alleviate the quenching? It is shown that even at the largest currently available resolution there is no clear evidence of power law scaling of the magnetic and kinetic energy spectra in turbulence. However, using subgrid scale modeling, some indications of asymptotic equipartition can be found. The frequently used first order smoothing approach to calculate the alpha effect and other transport coefficients is contrasted with the superior minimal tau approximation. The possibility of catastrophic alpha quenching is discussed as a result of magnetic helicity conservation. Magnetic and current helicity fluxes are shown to alleviate catastrophic quenching in the presence of shear. Evidence for strong large scale dynamo action, even in the absence of helicity in the forcing, is presented.

description: Policies to devolve responsibility for natural resource management to local bodies have become widespread in the past 20 years. Although the theoretical advantages of user management have been convincing and the impetus for devolution policies strong, the actual outcomes of devolution programs in various sectors and countries have been mixed. This paper summarizes key research findings on factors that contribute to effective devolution programs in the forestry, fisheries, irrigation, and rangelands sectors, which were presented and discussed at an international Policy Workshop on Property Rights, Collective Action and Devolution of Natural Resource Management, June 21-25, 1999, in Puerto Azul, the Philippines. We begin by addressing the language of devolution in an effort to clarify concepts and terminology that enable a more productive discussion of the issues. This is followed by some of the key arguments made by the workshop participants for devolving rights to resources to local users. Policies and factors that have the potential to strengthen or constrain devolution are addressed at a broad level before looking specifically at how property rights and collective action institutions can shape devolution outcomes. Whereas some factors cut across resource sectors and regions, others are more specific to their contexts. In all cases, proponents of devolution of rights to resource users struggle to understand better what elements facilitate collective action and what factors hinder its creation and sustainability. Finally, a set of recommended frameworks formulated by the workshop participants highlight the potential for fostering a devolution process that leads to the simultaneous improvement of natural resource management and the livelihoods of the poor.

description: Very recently, the Xenon1T collaboration has reported an intriguing electron recoil excess, which may imply for light dark matter. In order to interpret this anomaly, we propose the atmospheric dark matter (ADM) from the inelastic collision of cosmic rays (CRs) with the atmosphere. Due to the boost effect of high energy CRs, we show that the light ADM can be fast-moving and successfully fit the observed electron recoil spectrum through the ADM-electron scattering process. Meanwhile, our ADM predicts the scattering cross section $σ_e \sim {\cal O}(10^{-38}- 10^{-39}$) cm$^{2}$, and thus can evade other direct detection constraints. The search for light meson rare decays, such as $η\to π+ \slashed E_T$, would provide a complementary probe of our ADM in the future.

description: The objective of this paper is to deeply analyze some of the theoretical and methodological implications linked to the definition, the characterization, the evaluation and the estimation of the economic results of a multifunction agricultural farm. A deep study of these aspects seems essential for two reasons. On one hand, society is pressing farms to enlarge the existing set of goods and services; on the other hand, sector policies offer to farms new opportunities, which regard the allocation of services linked to the different functions that agriculture is able to carry out. In these conditions, in order to make the entrepreneur able to decide which services to set in motion, considering the economical input that their activation could bring to the farm, it is fundamental to identify an analytic method that is capable to estimate and evaluate the economic results of a multifunction farm.

Renormalization-Group Improved Calculation of the B->Xs+gamma Branching Ratio

description: Using results on soft-collinear factorization for inclusive B-meson decay distributions, a systematic study of the partial $B\to X_sγ$ decay rate with a cut $E_γ> E_0$ on photon energy is performed. For values of $E_0$ below about 1.9 GeV, the rate can be calculated without reference to shape functions using a multi-scale operator product expansion (MSOPE). The transition from the shape-function region to the MSOPE region is studied analytically. The resulting prediction for the $B\to X_sγ$ branching ratio depends on three large scales: $m_b$, $\sqrt{m_bΔ}$, and $Δ=m_b-2E_0$. Logarithms associated with these scales are resummed at next-to-next-to-leading logarithmic order. While power corrections in $Λ_{QCD}/Δ$ turn out to be small, the sensitivity to the scale $Δ\approx 1.1$ GeV (for $E_0\approx 1.8$ GeV) introduces significant perturbative uncertainties, which so far have been ignored. The new theoretical prediction for the $B\to X_sγ$ branching ratio with $E_γ\ge 1.8$ GeV is $Br(B\to X_sγ)=(3.38_{-0.42-0.30}^{+0.31+0.32})\times 10^{-4}$, where the first error is an estimate of perturbative uncertainties and the second one reflects uncertainties in input parameters. With this cut $(89_{-7}^{+6}\pm 1)%$ of all events are contained. The implications of larger theory uncertainties for New Physics searches are briefly explored with the example of the type-II two-Higgs-doublet model, for which the lower bound on the charged-Higgs mass is reduced compared with previous estimates to approximately 200 GeV at 95% confidence level.

description: Στην παρούσα διπλωματική εργασία διεξήχθησαν μετρήσεις ταχυτήτων χρονικά μεταβαλλόμενης ροής νερού σε μικροκανάλι τραπεζοειδούς διατομής βάθους 130 μm με τη μέθοδο micro P.I.V. Για το λόγο αυτό, η λειτουργία αντλίας τύπου σύριγγας, εμπορικού τύπου, ελέγχθηκε με τη βοήθεια μικροελεγκτή ώστε η παροχή της αντί σταθερή να είναι χρονικά μεταβαλλόμενη. Έγιναν μετρήσεις για παροχή περιόδου 16 sec μεταβαλλόμενης ημιτονοειδώς μεταξύ 20 και 40 μl/min. Εν φάσει μετρήσεις ελήφθησαν σε διάφορα βάθη για 16 φάσεις της περιόδου, στέλνοντας ένα σήμα σκανδαλισμού στο σύστημα micro PIV από τον μικροελεγκτή κάθε 1 sec. Λόγω του μικρού αριθμού Womersley (<1), δεν υπήρχε διαφορά φάσης στην ταχύτητα του ρευστού μεταξύ της περιοχής κοντά στον τοίχο και το κέντρο του καναλιού. Ο λόγος της μέγιστης προς την μέση ταχύτητα ήταν περίπου 1.7 ενώ ο μέγιστος λόγος του πλάτους της ταχύτητας προς τη μέση ήταν 32%.
description: n the context of the present Diploma thesis, the velocity field in a 130 micron deep microchannel of a trapezoidal cross section was measured, employing a micro-PIV system for a time dependent flow rate. For this purpose, a commercial syringe type pump, supplying de-ionized water to the channel with a constant flow rate, was externally controlled by a microcontroller so that the flow rate varies sinusoidally in time with a non zero mean. Phase averaged velocity profiles were taken at various depths sending a trigger signal from the microcontroller to the PIV system with a frequency of 1 Hz. Measurements were done for a flow rate varying between 20 to 40 μl/min for a period of 16 sec. Due to the small Womersley number (<1), there was no phase difference of the fluid velocity between the region close to the wall and that at the center plane of the microchannel. The ratio of the maximum to the average mean velocity was approximately 1.7 and the maximum ratio of the velocity amplitude to the mean was 32%.

description: We present a new version of PyR@TE, a Python tool for the computation of renormalization group equations for general, non-supersymmetric gauge theories. Its new core relies on a recent paper by Poole & Thomsen (arXiv:1906.04625) to compute the $β$-functions. In this framework, gauge kinetic mixing is naturally implemented, and the Weyl consistency relations between gauge, quartic and Yukawa couplings are automatically satisfied. One of the main new features is the possibility for the user to compute the gauge coupling $β$-functions up to the three-loop order. Large parts of the PyR@TE code have been rewritten and improved, including the group theory module PyLie. As a result, the overall performance in terms of computation speed was drastically improved and the model file is more flexible and user-friendly.
