description: This study investigates the optimal agricultural land use allocation and nitrogen application to a representative Japanese farm. The site-specific nature of numerous agri-environmental issues necessitates analysis at a disaggregated level in order to capture the underlying heterogeneity of agricultural productivity and environmental sensitivity across different parcels of land. This study adopts an integrated approach—a decision-making economic model for representative farms is combined with a stylized site-specific biophysical model, which quantifies the impact of different policy instruments on agricultural production practices and on multiple environmental effects. This model estimates the government budget outlays and social welfare, which require monetary valuation of environmental effects as well as of crop production. In addition to several agri-environmental policy scenarios, this study investigates the impact of the rice production adjustment policy, wherein a rice production quota is allocated to each region on the basis of the sales records for the previous two years. According to the simulation results, there is greater increase in social welfare when farmers are paid in order to reduce chemical fertilizer applications rather than by levying a nitrogen tax. Regarding carbon sequestration, the modelling exercise indicates that an agrienvironmental payment depending on the level of application of organic fertilizer (manure) is preferable; however, the social welfare derived by payments on the basis of the application of a minimum organic matter, which may avoid increasing the fiscal budget burden (on account of the increased application of organic matter on paddy fields), is higher than that derived by unit payments depending on the level of application of organic matter. The relaxation of the rice production quota results in an increase in social welfare. This integrated model approach is subject to limitations with respect to the data, model parameters, as well as economic and biophysical relationships. However, this approach is a valuable tool for enabling policy makers to design and implement effective and efficient policies.

description: Agri-environmental programs in Japan have generally been promoted through the provision of fixed payments for certain environment-friendly farming and management practices. However, the auctioning of agrienvironmental contracts is a noteworthy alternative for the furtherance of such programs. Conservation auctions are used to enhance the cost-effectiveness of public expenses and have been employed in practice as well as tested in various pilot projects in some countries. This study uses an experimental economics method to factor the risk attitude of participants into a comparison of uniform price (UP) auctions and discriminatory price (DP) auctions. Although some studies have compared fixed payments, UP auctions, and DP auctions, the superiority or inferiority of these strategies depends on the settings of an experiment. Consequently, experiments reflecting the Japanese situation could provide further insight into the advantages of each of these methods, and be used to guide policy design. In addition, the study also examines the effects of participants’ risk attitudes on auction performance. Its principal conclusion is that DP auctions outperform UP auctions; this is in line with the findings of previous studies. This empirical research furthers our understanding of environmental auctions in a first step toward the design of such auctions, but field experiments using real farmers should be conducted in order to help corroborate research conclusions before these are applied to the real world.

description: Aktuelle Strategien zum Forschungsdatenmanagement im deutschsprachigen Raum betonen immer wieder die Rolle der Fachcommunities. Die Disziplinen selbst sollen ihren Umgang mit Forschungsdaten reflektieren und eigene fachspezifische Empfehlungen entwickeln. Von den geisteswissenschaftlichen Fächern haben bisher (Stand April 2018) nur wenige auf die wissenschaftspolitischen Impulse reagiert. Die Gesellschaft für Musikforschung hat 2018 in einem Memorandum erste Überlegungen für ihr Fach dargelegt, ohne jedoch genauer zu klären, was musikwissenschaftliche Forschungsdaten sind oder was einen guten Umgang mit ihnen auszeichnet.Die vorliegende Arbeit setzt sich mit den Besonderheiten geisteswissenschaftlicher Forschungsdaten auseinander und wertet das Forschungsdatenmanagement in musikwissenschaftlichen und musikpädagogischen Dissertationen aus. Als Sample dienen 45 der 51 Arbeiten, die im Jahr 2015 an Universitäten und Musikochschulen in Deutschland angenommen wurden. Es wird untersucht, welche Forschungsmethoden die Promovierenden nutzen, mit welchen Arten von Quellen sie arbeiten und wie sie mit digitalen Forschungsdaten umgehen, die in den Promotionsprojekten entstanden sind. Auch Hinweise auf unveröffentlichte Daten und mögliche Gründe für deren Nichtveröffentlichung werden aufgespürt. Exkurse behandeln das Publikationsverhalten der angehenden Wissenschaftlerinnen und Wissenschaftler sowie typische Probleme beim Nachweis digital vorliegender Quellen. Urheberrechtliche Rahmenbedingungen und Fallstricke beim Veröffentlichen von Dissertationen und dazugehörigen Daten werden exemplarisch dargestellt.Die Untersuchung konkretisiert empirisch, mit welchen Forschungsmethoden, welchen Quellen und welchen Arten von Forschungsdaten in den Fächern Musikwissenschaft und Musikpädagogik zu rechnen ist. Darauf aufbauend werden Handlungsfelder für musikwissenschaftliches Forschungsdatenmanagement identifiziert. Damit werden Fachcommunities und Infrastruktureinrichtungen gleichermaßen adressiert. Die Studie soll eine Anregung für die anstehende fachinterne Diskussion geben. Sie kann als Vorstudie für das Erarbeiten von fachspezifischen Regeln für das Forschungsdatenmanagement in Musikwissenschaft und Musikpädagogik dienen. Die vorgestellte Methodik ist übertragbar auf andere, nicht nur geisteswissenschaftliche Fächer.

description: We study a model of a corporation which has the possibility to choose various production/business policies with different expected profits and risks. In the model there are restrictions on the dividend distribution rates as well as restrictions on the risk the company can undertake. The objective is to maximize the expected present value of the total dividend distributions. We outline the corresponding Hamilton-Jacobi-Bellman equation, compute explicitly the optimal return function and determine the optimal policy. As a consequence of these results, the way the dividend rate and business constraints affect the optimal policy is revealed. In particular, we show that under certain relationships between the constraints and the exogenous parameters of the random processes that govern the returns, some business activities might be redundant, that is, under the optimal policy they will never be used in any scenario.

description: Significant progress in the classification of Fermi unassociated sources , has led to an increasing number of blazars are being found. The optical spectrum is effectively used to classify the blazars into two groups such as BL Lacs and flat spectrum radio quasars (FSRQs). However, the accurate classification of the blazars without optical spectrum information, i.e., blazars of uncertain type (BCUs), remains a significant challenge. In this paper, we present a principal component analysis (PCA) and machine learning hybrid blazars classification method. The method, based on the data from Fermi LAT 3FGL Catalog, first used the PCA to extract the primary features of the BCUs and then used a machine learning algorithm to further classify the BCUs. Experimental results indicate that the that the use of PCA algorithms significantly improved the classification. More importantly, comparison with the Fermi LAT 4FGL Catalog, which contains the spectral classification of those BCUs in the Fermi-LAT 3FGL Catalog, reveals that the proposed classification method in the study exhibits higher accuracy than currently established methods; specifically, 151 out of 171 BL Lacs and 19 out of 24 FSRQs are correctly classified.

description: We investigate the transport properties of a classical wave propagating through a quasi-periodic Fibonacci array of waveguide segments in the form of loops. The formulation is general, and applicable for electromagnetic or acoustic waves through such structures. We examine the conditions for resonant transmission in a Fibonacci waveguide structure. The local positional correlation between the loops are found to be responsible for the resonance. We also show that, depending on the number of segments attached to a particular loop, the intensity at the nodes displays a perfectly periodic or a self-similar pattern. The former pattern corresponds to a perfectly extended mode of propagation, which is to be contrasted to the electron or phonon characteristics of a pure one dimensional Fibonacci quasi-crystal.

description: Self-cleaning surfaces often make use of superhydrophobic coatings that repel water. Here, we report a hydrophobic Si nanospring surface, that effectively suppresses wetting by repelling water droplets. We investigated the dynamic response of Si nanospring arrays fabricated by glancing angle deposition. The vertical standing nanospring arrays were approximately 250 nm tall and 60 nm apart, which allowed the droplets to rebound within a few milliseconds after contact. Amazingly, the morphology of the nanostructures influences the impact dynamics. The rebound time and coefficient of restitution were also found to be higher for Si nanosprings than vertical SI columns. It has been proposed that the restoring force of the Si nanosprings may be responsible for the water droplet rebound and can be explained by considering the droplet/nanospring surface as a coupled spring system. These nanospring surfaces may find applications in self-cleaning windows, liquid-repellent exteriors, glass panels of solar cells, and antifouling agents for roof tiling.

description: In the past year, a new non-supersymmetric framework for electroweak symmetry breaking (with or without Higgs) involving SU(2)_L * SU(2)_R * U(1)_{B-L} in higher dimensional warped geometry has been suggested. In this work, we embed this gauge structure into a GUT such as SO(10) or Pati-Salam. We showed recently (in hep-ph/0403143) that in a warped GUT, a stable Kaluza-Klein fermion can arise as a consequence of imposing proton stability. Here, we specify a complete realistic model where this particle is a weakly interacting right-handed neutrino, and present a detailed study of this new dark matter candidate, providing relic density and detection predictions. We discuss phenomenological aspects associated with the existence of other light (

Measurement and prediction of gas hydrate equilibrium conditions in the presence of inhibitors
Creators: name: Wu, Huijie
Publisher: name: University of British Columbia
Year: 2009

description: Gas hydrates are crystals which are formed by water and small gas molecules at low temperature and high pressure. Hydrate for many years have been a problem in o i l and gas industries because hydrate formation may plug the pipelines or valves and might also cause blowout in the drilling operations. In order to avoid hydrate formation, inhibitors are introduced to increase the pressure needed at a given temperature for hydrates formation. Generally used inhibitors in oil and gas industries are methanol, glycerol, ethylence glycol and triethylene glycol. Knowledge of the equilibrium hydrate-forming conditions is necessary for the rational and economic design of processes in the chemical, oil, gas, and other industries where hydrate formation is encountered. It is important to measure the incipient hydrate formation conditions for the systems containing different inhibitors, and also it is important to have available reliable methods for calculating the impact of the addition of these chemicals into the aqueous phase on the equilibrium hydrate formation conditions (inhibiting effect). In this work, the inhibiting effects of triethylene glycol (TEG) and glycerol in methane-ethane and methane-propane gas mixture hydrate formation systems were measured. The data showed that TEG (20.0wt% and 30.0wt %) and glycerol (20.0wt %) have considerable inhibiting effect on hydrate formation. These data are also valuable for validating the hydrate prediction models. Several models have been published based on cubic equations of state. In this work the Trebble-Bishnoi equation was used. The results were found to be in very good agreement with the data. The statistical associating fluid theory (SAFT) equation of state was also employed for the prediction of the thermodynamic inhibiting effect of methanol, glycerol, ethylene glycol and triethylene glycol on single gas hydrate formation. The results were found to be in satisfactory to excellent agreement with the experimental data. The SAFT equation takes into account hard sphere repulsion, hard chain formation, dispersion and association. This enables this model to be able to correlate and predict successfully systems containing water, alcohols and hydrocarbons.

description: We investigate which practical constraints are imposed by foregrounds to the detection of the B-mode polarization generated by gravitational waves in the case of experiments of the type currently being planned. Because the B-mode signal is probably dominated by foregrounds at all frequencies, the detection of the cosmological component depends drastically on our ability for removing foregrounds. We provide an analytical expression to estimate the level of the residual polarization for Galactic foregrounds, according to the method employed for their subtraction. We interpret this result in terms of the lower limit of the tensor-to-scalar ratio r that allows to disentangle the cosmological B-mode polarization from the foregrounds contribution. Polarized emission from extragalactic radio sources and gravitational lensing is also taken into account. As a first approach, we consider the ideal limit of an instrumental noise--free experiment: for a full--sky coverage and a degree resolution, we obtain a limit of r~10^(-4). This value can be improved by high--resolution experiments and, in principle, no clear fundamental limit on the detectability of gravitational waves polarization is found. Our analysis is also applied to planned or hypothetical future polarization experiments, taking into account expected noise levels.

description: 	Type 1 diabetes (T1D) is characterized by autoimmune-mediated destruction of insulin-producing ? cells in pancreatic islets. Infiltrating immune cells secrete high levels of pro-inflammatory cytokines that disrupt islet function and lead to ?-cell death in early T1D. The peri-islet extracellular matrix (ECM) serves as a protective barrier and is crucial for islet survival. Specifically, laminin supports ?-cell survival via transmembrane integrins. In several cell types, laminin receptor activity is linked to protein kinase C ? (PKC?), a key regulator of apoptosis. Laminin is also known to engage the PI3K/Akt pro-survival pathway in ? cells. Thus, we hypothesize that loss of laminin interactions with the islet in T1D enhances cytokine-mediated ?-cell death via PKC? activation and dysregulation of the PI3K/Akt pro-survival pathway. To investigate laminin’s protective role, we encapsulated C57Bl/6 mouse islets in a 3D reverse thermal gel (RTG) alone or functionalized with laminin (RTG-LAM) and treated them with a pro-inflammatory cytokine cocktail (10ng/mL TNF-?, 5ng/mL IL-1? and 10ng/mL IFN-?) for 24 hours. Islet interactions with laminin significantly protected against cytokine-induced death (p=0.027). Using a membrane-targeted FRET biosensor in MIN6 cells and a GFP-tagged PKC? fusion protein in intact islets, we found that laminin reduced PKC? activity at the cell membrane (p=0.039). To determine if laminin in the RTG activates a downstream pro-survival pathway in ?-cells, we will perform western blot analysis on components of the PI3K/Akt signaling pathway. Overall, our results suggest that laminin interactions protect islets from cytokine-induced apoptosis, which may be mediated by PKC? and downstream signaling pathways.

description: We propose an ansatz for OPE coefficients in chaotic conformal field theories which generalizes the Eigenstate Thermalization Hypothesis and describes any OPE coefficient involving heavy operators as a random variable with a Gaussian distribution. In two dimensions this ansatz enables us to compute higher moments of the OPE coefficients and analyse two and four-point functions of OPE coefficients, which we relate to genus-2 partition functions and their squares. We compare the results of our ansatz to solutions of Einstein gravity in AdS$_3$, including a Euclidean wormhole that connects two genus-2 surfaces. Our ansatz reproduces the non-perturbative correction of the wormhole, giving it a physical interpretation in terms of OPE statistics. We propose that calculations performed within the semi-classical low-energy gravitational theory are only sensitive to the random nature of OPE coefficients, which explains the apparent lack of factorization in products of partition functions.

description: We sketch the foundations of classical electrodynamics, in particular the transition that took place when Einstein, in 1915, succeeded to formulate general relativity. In 1916 Einstein demonstrated that, with a choice of suitable variables for the electromagnetic field, it is possible to put Maxwell's equation into a form that is covariant under general coordinate transformations. This unfolded, by basic contributions of Kottler, Cartan, van Dantzig, Schouten & Dorgelo, Toupin & Truesdell, and Post, to what one may call {\em premetric classical electrodynamics.} This framework will be described shortly. An analysis is given of the physical dimensions involved in electrodynamics and subsequently the question of units addressed. It will be pointed out that these results are untouched by the generalization of classical to quantum electrodynamics (QED). We compare critically our results with those of {\sl L.B. Okun} which he had presented at a recent conference.

description: Recently, Imaging Ultraviolet Spectrograph (IUVS) on-board Mars Atmosphere and Volatile EvolutioN (MAVEN) satellite observed CO$^+$ first-negative band limb emission in the Martian upper atmosphere. We aim to explore the photochemical processes in the Martian upper atmosphere, which drives this band emission. A photochemical model is developed to study the excitation processes of CO$^+$ first-negative band emission (B$^2Σ^+ \rightarrow$ X$^2Σ^+$) in the upper atmosphere of Mars. The number density profiles of CO$_2$ and CO from two different models, viz., Mars Climate Database (MCD) and Mars Global Ionosphere-Thermosphere (MGIT) are used to determining the limb intensity of this band emission. On increasing the CO density by a factor of 4 and 8 in MCD and MGIT models, respectively, the modelled CO$^+$ first-negative band limb intensity profile is found to be consistent with IUVS/MAVEN observation. In this case, the intensity of this band emission is significantly determined by the ionization of CO by solar photons and photoelectrons, and the role of dissociative ionization of CO$_2$ is negligible. Since CO is the major source of the CO$^+$(B$^2Σ^+$), we suggest that the observed CO$^+$ first-negative band emission intensity can be used to retrieve the CO density in the Martian upper atmosphere for the altitudes above 150 km.

description: The strong irrigation tradition has sustained the broad based community interest in irrigation. The result is a very complex institutional milieu in which a set of formally established irrigation rules and organizations exists side by side with an intricate set of social institutions. The two sets act like a dual system often in conflict with each other. The authors, while analyzing the present institutional barriers, have highlighted the importance of irrigation rules and procedures in the institutional framework.
A Knee-Point in the Rotation-Activity Scaling of Late-type Stars with a Connection to Dynamo Transitions

description: The magnetic activity of late-type stars is correlated with their rotation rates. Up to a certain limit, stars with smaller Rossby numbers, defined as the rotation period divided by the convective turnover time, have higher activity. A more detailed look at this rotation-activity relation reveals that, rather than being a simple power law relation, the activity scaling has a shallower slope for the low-Rossby stars than for the high-Rossby ones. We find that, for the chromospheric CaII H&K activity, this scaling relation is well modelled by a broken two-piece power law. Furthermore, the knee-point of the relation coincides with the axisymmetry to non-axisymmetry transition seen in both the spot activity and surface magnetic field configuration of active stars. We interpret this knee-point as a dynamo transition between dominating axi- and non-axisymmetric dynamo regimes with a different dependence on rotation and discuss this hypothesis in the light of current numerical dynamo models.

Magnetically Driven Accretion in the Kerr Metric III: Unbound Outflows

description: We have carried out fully relativistic numerical simulations of accretion disks in the Kerr metric. In this paper we focus on the unbound outflows that emerge self-consistently from the accretion flow. These outflows are found in the axial funnel region and consist of two components: a hot, fast, tenuous outflow in the axial funnel proper, and a colder, slower, denser jet along the funnel wall. Although a rotating black hole is not required to produce these unbound outflows, their strength is enhanced by black hole spin. The funnel-wall jet is excluded from the axial funnel due to elevated angular momentum, and is also pressure-confined by a magnetized corona. The tenuous funnel outflow accounts for a significant fraction of the energy transported to large distances in the higher-spin simulations. We compare the outflows observed in our simulations with those seen in other simulations.

Describing Console I/O Behavior for Testing Student Submissions in Haskell

description: We present a small, formal language for specifying the behavior of simple console I/O programs. The design is driven by the concrete application case of testing interactive Haskell programs written by students. Specifications are structurally similar to lexical analysis regular expressions, but are augmented with features like global variables that track state and history of program runs, enabling expression of an interesting range of dynamic behavior. We give a semantics for our specification language based on acceptance of execution traces. From this semantics we derive a definition of the set of all traces valid for a given specification. Sampling that set enables us to mechanically check program behavior against specifications in a probabilistic fashion. Beyond testing, other possible uses of the specification language in an education context include related activities like providing more helpful feedback, generating sample solutions, and even generating random exercise tasks.

description: This paper has a twofold contribution. The first is a data driven approach for predicting the Covid 19 pandemic dynamics, based on data from more advanced countries. The second is to report and discuss the results obtained with this approach for Brazilian states, as of May 4th, 2020. We start by presenting preliminary results obtained by training an LSTM SAE network, which are somewhat disappointing. Then, our main approach consists in an initial clustering of the world regions for which data is available and where the pandemic is at an advanced stage, based on a set of manually engineered features representing a country response to the early spread of the pandemic. A Modified Auto-Encoder network is then trained from these clusters and learns to predict future data for Brazilian states. These predictions are used to estimate important statistics about the disease, such as peaks. Finally, curve fitting is carried out on the predictions in order to find the distribution that best fits the outputs of the MAE, and to refine the estimates of the peaks of the pandemic. Results indicate that the pandemic is still growing in Brazil, with most states peaks of infection estimated between the 25th of April and the 19th of May 2020. Predicted numbers reach a total of 240 thousand infected Brazilians, distributed among the different states, with São Paulo leading with almost 65 thousands estimated, confirmed cases. The estimated end of the pandemics (with 97 percent of cases reaching an outcome) starts as of May 28th for some states and rests through August 14th, 2020.

description: In this paper, we establish an explicit correspondence between kissing reflection groups and critically fixed anti-rational maps. The correspondence, which is expressed using simple planar graphs, has several dynamical consequences. As an application of this correspondence, we give complete answers to geometric mating problems for critically fixed anti-rational maps.
