description: We compare multi-epoch sub-arcsecond VLA imaging of the 22 GHz water masers toward the massive protocluster NGC6334I observed before and after the recent outburst of MM1B in (sub)millimeter continuum. Since the outburst, the water maser emission toward MM1 has substantially weakened. Simultaneously, the strong water masers associated with the synchrotron continuum point source CM2 have flared by a mean factor of 6.5 (to 4.2 kJy) with highly-blueshifted features (up to 70 km/s from LSR) becoming more prominent. The strongest flaring water masers reside 3000 au north of MM1B and form a remarkable bow shock pattern whose vertex coincides with CM2 and tail points back to MM1B. Excited OH masers trace a secondary bow shock located ~120 au downstream. ALMA images of CS (6-5) reveal a highly-collimated north-south structure encompassing the flaring masers to the north and the non-flaring masers to the south seen in projection toward the MM3-UCHII region. Proper motions of the southern water masers over 5.3 years indicate a bulk projected motion of 117 km/s southward from MM1B with a dynamical time of 170 yr. We conclude that CM2, the water masers, and many of the excited OH masers trace the interaction of the high velocity bipolar outflow from MM1B with ambient molecular gas. The previously-excavated outflow cavity has apparently allowed the radiative energy of the current outburst to propagate freely until terminating at the northern bow shock where it strengthened the masers. Additionally, water masers have been detected toward MM7 for the first time, and a highly-collimated CS (6-5) outflow has been detected toward MM4.

Shifts in Portfolio Preferences of International Investors: An Application to Sovereign Wealth Funds

description: Reversals in capital inflows can have severe economic consequences. This paper develops a dynamic general equilibrium model to analyse the effect on interest rates, asset prices, investment, consumption, output, the exchange rate and the current account of a shift in portfolio preferences of foreign investors. The model has two countries and two asset classes (equities and bonds). It is characterized by imperfect substitutability between assets and allows for endogenous adjustment in interest rates and asset prices. Therefore, it accounts for capital gains arising from equity price movements, in addition to valuation effects caused by changes in the exchange rate. To illustrate the mechanics of the model, we calibrate it to analyse the consequences of an increase in the importance of Sovereign Wealth Funds (SWFs). Specifically, we ask what would happen if 'excess' reserves held by Emerging Markets were transferred from central banks to SWFs. We look separately at two diversification paths: one in which SWFs keep the same allocation across bonds and equities as central banks, but move away from dollar assets (path 1); and another in which they choose the same currency composition as central banks, but shift from US bonds to US equities (path 2). In path 1, the dollar depreciates and US net debt falls on impact and increases in the long run. In path 2, the dollar depreciates and US net debt increases in the long run. In both cases, there is a reduction in the 'exorbitant privilege', i.e., the excess return the US receives on its assets over what it pays on its liabilities. The model is applicable to other episodes in which foreign investors change the composition of their portfolios.

description: Current methods of disseminating scholarly information focus on the use of journals who retain exclusive rights in the material they publish. Using a simple model we explore the reasons for the development of the traditional journal model, why it is no longer efficient and how it could be improved upon. One of our main aims is to go beyond the basic question of distribution (access) to that of filtering, i.e. the process of matching information with the scholars who want it. With the volume of information production ever growing - and attention ever more scarce - filtering is becoming crucial and digital technology offers the possibility of radical innovation in this area. In particular, distribution and filtering can be separated allowing filtering to be made open and decentralized. This would promises to deliver dramatic increases in transparency and efficiency as well as greatly increased innovation in related product, processes and services.
Upstream vs. Downstream CO2 Trading: A Comparison for the Electricity Context

description: In electricity, “downstream” CO2 regulation requires retail suppliers to buy energy from a mix of sources so that their weighted emissions satisfy a standard. It has been argued that such “load-based” regulation would solve emissions leakage, cost consumers less, and provide more incentive for energy efficiency than traditional source-based cap-andtrade programs. Because pure load-based trading complicates spot power markets, variants (GEAC and CO2RC) that separate emissions attributes from energy have been proposed. When all energy producers and consumers come under such a system, these load-based programs are equivalent to source-based trading in which emissions allowances are allocated by various rules, and have no necessary cost advantage. The GEAC and CO2RC systems are equivalent to giving allowances free to generators, and requiring consumers either to subsidize generation or buy back excess allowances, respectively. As avoided energy costs under source-based and pure load-based trading are equal, the latter provides no additional incentive for energy efficiency. The speculative benefits of load-based systems are unjustified in light of their additional administrative complexity and cost, the threat that they pose to the competitiveness and efficiency of electricity spot markets, and the complications that would arise when transition to a federal cap-and-trade system occurs.
Measurement of the flux of atmospheric muons with the CAPRICE94 apparatus

Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A new measurement of the momentum spectra of both positive and negative muons as function of atmospheric depth was made by the balloon-borne experiment CAPRICE94. The data were collected during ground runs in Lynn Lake on the 19-20th of July 1994 and during the balloon flight on the 8-9th of August 1994. We present results that cover the momentum intervals 0.3-40 GeV/c for negative muons and 0.3-2 GeV/c for positive muons, for atmospheric depths from 3.3 to 1000 g/cm**2, respectively. Good agreement is found with previous measurements for high momenta, while at momenta below 1 GeV/c we find latitude dependent geomagnetic effects. These measurements are important cross-checks for the simulations carried out to calculate the atmospheric neutrino fluxes and to understand the observed atmospheric neutrino anomaly.

description: This paper attempts to assess the social welfare impact of the restructuring and privatisation of the electricity market in Peru. The target companies, Electrolima and Electro Sur Medio, account for 64 percent of the total distribution market and 100 per cent of the privatised distribution companies respectively. Actual and counterfactual operating costs are examined. A separate analysis is performed for each company, due to the differences in terms of economies of scale and market structure. The benefits of being connected were also computed based on counterfactual scenarios. Companies that were not privatised (benchmark companies) were used for making appropriate comparisons and for determining our preferred counterfactual cost decline. Benchmark companies were also important for analysing the trend in quality issues. The results show that privatisation was worthwhile and that the social welfare of being connected has an important contribution on it. Government and producers benefited the most and consumers the least due to price increase.
Formation of a planetary Laplace resonance through migration in an eccentric disk - The case of GJ876

description: Orbital mean motion resonances in planetary systems originate from dissipative processes in disk-planet interactions that lead to orbital migration. In multi-planet systems that host giant planets, the perturbation of the protoplanetary disk strongly affects the migration of companion planets. By studying the well-characterized resonant planetary system around GJ 876 we aim to explore which effects shape disk-driven migration in such a multi-planet system to form resonant chains. We modelled the orbital migration of three planets embedded in a protoplanetary disk using two-dimensional locally isothermal hydrodynamical simulations. We performed a parameter study by varying the disk thickness, $α$ viscosity, mass as well as the initial position of the planets. Moreover, we have analysed and compared simulations with various boundary conditions at the disk's inner rim. We find that due to the high masses of the giant planets, substantial eccentricity can be excited in the disk. This results in large variations of the torque acting on the outer lower-mass planet, which we attribute to a shift of Lindblad and corotation resonances due to disk eccentricity. Depending on disk parameters, the migration of the outer planet can be stopped in a non-resonant state. In other models, the outer planet is able to open a partial gap and to circularize the disk again, later entering a 2:1 resonance with the most massive planet in the system to complete the observed Laplace resonance. Disk-mediated interactions between planets due to spiral waves and excitation of disk eccentricity cause deviations from smooth inward migration of exterior lower mass planets. Self-consistent modelling of the disk-driven migration of multi-planet systems is thus mandatory. Our results are compatible with a late migration of the outermost planet into the resonant chain, when the giant planet pair already is in resonance.

Absorption and emission features of $^7$Be{\sc II} in the outburst spectra of V838 Her (Nova Her 1991)

description: High and low resolution $IUE$ spectra of V838 Her in the early outburst stages exhibit a strong absorption feature shortward of $λ$3130. We discuss the nature of this spectral feature and provide convincing evidence that it corresponds to the blue-shifted resonance doublet of singly-ionized $^7$Be, recently discovered in other novae. During the evolution of the outburst the appearance of an emission feature close to $λ$3130 is also identified as $^7$Be II $λ$3132 because the usual identification as the O III $λ$3133.7 Bowen fluorescence line is hardly compatible with both the known oxygen under-abundance in the nova ejecta and the low optical depths in the nebula due to the high outflow velocity. The average $^7$Be abundance relative to hydrogen, estimated by four different methods, i.e. the $^7$Be II / Mg II absorption ratio, and the $^7$Be II / Mg II, $^7$Be II / He II$_{1640}$, and $^7$Be II / H$β$ emission ratios is N(Be)/N(H) $\approx$ 2.5 $\times 10^{-5}$ (by number), i.e. $\approx$ 1.7 $\times 10^{-4}$ by mass. This corresponds to an overproduction of $^7$Be by about 1 dex in comparison with the theoretical models of massive CO and ONe novae. Since $^7$Be all converts into $^7$Li, the $^7$Be/H abundance implies a $^7$Li/H overabundance of about 4 dex over the $^7$/H meteoritic value and indicates a total ejected mass of $^7$Li of $\approx$ 9.5$\times$10$^{-10}$ $M_{\odot}$. These data are in line with previous observations and indicate that large amounts of $^7$Li can be synthesized in a variety of novae, including very fast ONe novae.

Previous results and general recommendations for divisible-good/multi-unit auctions provides guidance on the design of the auction format, setting the reservation price, the rationing rule, and restrictions on the offer curves in wholesale electricity auctions.

Supplying Synthetic Crude Oil from Canadian Oil Sands: A Comparative Study of the Costs and CO2 Emissions of Mining and In-Situ Recovery

Social cost of carbon

description: High crude oil prices and the eventual decline of conventional oil production raise the issue of alternative fuels such as non-conventional oil. The paper describes a simple probabilistic model of the costs of synthetic crude oil (SCO) produced from Canadian oil sands. Synthetic crude oil is obtained by upgrading bitumen that is first produced through mining or in-situ recovery techniques. This forward-looking analysis quantifies the effects of learning and production constraints on the costs of supplying synthetic crude oil from Canadian bitumen deposits. The results show the uncertainties associated with the future costs of synthetic crude oil. Carbon costs have a large impact of the total costs of synthetic crude oil, in particular in the case of synthetic crude oil from in-situ bitumen, due to the carbon-intensity of the recovery techniques. The influence of each parameter on the supply costs is examined. In the case of mined SCO, the maximum production rate, the ultimate recovery rate and the depletion parameters show the largest influence on the results, while learning parameters dominate in the case of in-situ SCO.

description: In the 1990s, J.H. Conway published a combinatorial-geometric method for analyzing integer-valued binary quadratic forms (BQFs). Using a visualization he named the "topograph," Conway revisited the reduction of BQFs and the solution of quadratic Diophantine equations such as Pell's equation. It appears that the crux of his method is the coincidence between the arithmetic group $PGL_2({\mathbb Z})$ and the Coxeter group of type $(3,\infty)$. There are many arithmetic Coxeter groups, and each may have unforeseen applications to arithmetic. We introduce Conway's topograph, and generalizations to other arithmetic Coxeter groups. This includes a study of "arithmetic flags" and variants of binary quadratic forms.

description: This study specifies and estimates a gravity model for inter-provincial migration in Indonesia. Using panel data for Indonesia’s 26 provinces for 5 survey years between 1930 and 2000 we show that throughout the twentieth century economic factors were more important in the explanation of inter-provincial migration patterns in Indonesia than planned migration policy aimed at the redistribution of the population. In addition, our regression analysis demonstrates that the urban primacy of Jakarta, Indonesia’s capital, had a strong effect on the direction and size of migration flows as well. Our findings thus suggest that the costly government-supported migration is not very successful and that a strongly centralized government induces migration flows to the capital. These findings have policy implications for other developing countries.

description: There has been a wide discussion on the different properties between carbon taxes, cap-and-trade schemes and hybrid instruments such as cap-and-trade schemes with price floors and ceilings. There has been less discussion on the incentives to investment that each of these instruments may provide. We build a three-period model to investigate the incentives offered to a large firm with diversified abatement options from such instruments when facing a choice between investing in lowcarbon technologies with potential learning benefits. We parameterise our model for a system similar to the EUETS and for two sample technologies, biomass for electricity and coal with carbon capture and storage. For both technologies we find that cap-and-trade schemes generate greater mean returns to such an investment than taxes, but with a wider distribution. We find that introducing price floors increase such mean returns while reducing the distribution, while ceilings further reduce the distribution, but also the mean and thus the overall incentives they offer will depend on the risk preference of the firm and scale of investment in relation to overall compliance costs.
UK Renewable Energy Policy Since Privatisation

Subjects: Renewable electricity

description: The aim of this paper is to look at the UK’s renewable energy policy in the context of its overall decarbonisation and energy policies. This will allow us to explore the precise nature of the ‘failure’ of UK renewables policy and to suggest policy changes which might be appropriate in light of the UK’s institutional and resource endowments. Our focus is on the electricity sector both in terms of renewable generation and to a lesser extent the facilitating role of electricity distribution and transmission networks. We will suggest that the precise nature of the failure of UK policy is rather more to do with societal preferences and the available mechanisms for encouraging social acceptability than it is to do with financial support mechanisms. Radical changes to current policy are required, but they must be careful to be institutionally appropriate to the UK. What we suggest is that current policies exhibit an unnecessarily low benefit to cost ratio, and that new policies for renewable deployment must pay close attention to cost effectiveness.

description: The He3 abundance is not constrained by helioseismic data. Mixing of He3 inside the solar core by processes not included in the solar standard model (SSM) has been recently proposed as possible solution to the solar neutrino problem. We have performed a model independent analysis of solar neutrino fluxes using practically arbitrary He3 mixing. In addition, we have been simultaneously varying within very wide ranges the temperature in the neutrino production zone and the astrophysical factors, S17 and S34, of the p+Be7 and He3+He4 cross sections. Seismic data are used as constraints, but the solar- luminosity constraint is not imposed. It is demonstrated that even allowing He3 abundances higher by factors up to 16 than in the SSM, temperatures 5% (or more) lower, the astrophysical factor S17 up to 40% higher, and varying S34 in the range (-20% ,+40%), the best fit is still more than 5 sigmas away from the observed fluxes. We conclude that practically arbitrary He3 mixing combined with independent variations of temperature and cross-sections cannot explain the observed solar neutrino fluxes.

We use the one dimensional heat diffusion equation with the appropriate solution in each layer and boundary conditions at the interfaces to calculate the heat transport in this bounded system. We also consider the heat flux at the surface of the samle as boundary condition instead of using a fixed tempertaure. From this, we obtain an expression for the efective thermal diffusivity of the composite sample in terms of the thermal diffusivity of its constituent materials whithout any approximations.

description: As developing countries seek to improve their economic prospects, electricity reform has been widely viewed as a central part of this effort.While the focus of most research to date has been at economy or utility level; there has been much less research on regional outcomes. India presents a unique case, as its states share a common economic and political system, whilst having been given considerable flexibility in how they implement reform, thus allowing a comparative analysis of alternative approaches. This study contributes through an econometric analysis of the determinants and impact of electricity reform in India, giving special regard to its political economy and regional diversity. It assesses how electricity reform in India has affected key economic variables that determine sectoral efficiency, prices and investment flows. We use panel data for 19 states, spanning 1991-2007, using dynamic panel data estimators. Results show that individual reform measures have affected key economic variables differently; thus the nature of reform in individual states would determine these economic outcomes. Findings suggest that due to political economy factors influencing reform, outcomes have tended to be adverse in the initial stages, as previously hidden distortions become apparent. The performance of reforms, however, may improve as it progresses beyond a ‘baseline’ level.

description: Following the discovery of blue large-amplitude pulsators (BLAPs), single star evolu- tion models of post red giant branch stars that have undergone a common envelope (CE) ejection in the form of a high mass loss rate have been constructed and analysed for pulsation stability. The effects of atomic diffusion, particularly radiative levitation, have been examined. Two principal models were considered, being post-CE stars of 0.31 and 0.46 M$_{\odot}$. Such stars are likely, in turn, to become either low-mass helium white dwarfs or core helium-burning extreme horizontal-branch stars. The inclusion of radiative levitation leads to opacity driven pulsations in both types of post-CE object when their effective temperatures are comparable to those of BLAPs, with similar periods. The extent of the instability region for models in these simulations, which are not in thermal balance, is larger than that found for static models, in agreement with previous theory. By comparing to observations, and making some simple evolutionary assumptions, we conclude the 0.31 M$_{\odot}$ star is the more likely candidate for BLAPs. The rate of period change is negative for both cases, so the origin of BLAPs with positive rates of period change remain uncertain.

description: While much of the literature on cross section dependence has focused mainly on estimation of the regression coefficients in the underlying model, estimation and inferences on the magnitude and strength of spill-overs and interactions has been largely ignored. At the same time, such inferences are important in many applications, not least because they have structural interpretations and provide useful interpretation and structural explanation for the strength of any interactions. In this paper we propose GMM methods designed to uncover underlying (hidden) interactions in social networks and committees. Special attention is paid to the interval censored regression model. Our methods are applied to a study of committee decision making within the Bank of England’s monetary policy committee.

description: Each cycle of a directed graph can be written as a linear combination of the circuits of a cycle basis for that directed graph. We define two new classes of cycle bases and show how each relates to the known classes of strictly fundamental cycle bases, zero-one cycle bases and integral cycle bases. We provide examples showing the significance of the Möbius band to constructing directed graphs, the bases of which are in some of these classes and not in other classes.

Constrained Dynamics for Quantum Mechanics I. Restricting a Particle to a Surface

description: We analyze constrained quantum systems where the dynamics do not preserve the constraints. This is done in particular for the restriction of a quantum particle in Euclidean n-space to a curved submanifold, and we propose a method of constraining and dynamics adjustment which produces the right Hamiltonian on the submanifold when tested on known examples. This method we hope will become the germ of a full Dirac algorithm for quantum constraints. We take a first step in generalising it to the situation where the constraint is a general selfadjoint operator with some additional structures.

Regulation, customer protection and customer engagement

description: The UK utility regulation framework developed in the 1980s was intended to improve on the restrictive, inefficient and burdensome regulatory approach in the US. But the UK regulatory process has itself now become increasingly burdensome. Meanwhile, utilities and customer groups in the US and Canada have developed methods of negotiating and settling regulatory issues that more directly reflect the interests of customers, often embody incentive price caps as in the UK, and avoid unduly burdensome regulatory processes. There is now scope for UK regulators to learn from overseas. This paper summarises these developments. It then examines how three UK utility regulators – the CAA, Ofgem and Ofwat - are responding to them. Briefly, the CAA has moved firmly in this direction, but Ofgem and Ofwat have nominally rejected it while seeking to secure many of the benefits of the approach via a less committed process. There is scope for governments to encourage a regulatory approach that offers the prospect of better outcomes for customers and a less onerous process for all concerned.

description: MicroRNAs (miRNAs) are a class of single-stranded non-coding small RNAs (sRNAs) that are 20–24 nucleotides (nt) in length. Extensive studies have indicated that miRNAs play important roles in plant growth, development and stress responses. With more copper (Cu) and copper containing compounds used as bactericides and fungicides in plants, Cu stress has become one of the serious environmental problems that affect plant growth and development. In order to uncover the hidden response mechanisms of Cu stress, two small RNA libraries were constructed from Cu-treated and water-treated (Control) leaves of ‘Summer Black’ grapevine. Following high-throughput sequencing and filtering, a total of 158 known and 98 putative novel miRNAs were identified in the two libraries. Among these, 100 known and 47 novel miRNAs were identified as differentially expressed under Cu stress. Subsequently, the expression patterns of nine Cu-responsive miRNAs were validated by quantitative real-time PCR (qRT-PCR). There existed some consistency in expression levels of Cu-responsive miRNAs between high throughput sequencing and qRT-PCR assays. The targets prediction of miRNAs indicates that miRNA may regulate some transcription factors, including AP2, SBP, NAC, MYB and ARF during Cu stress. The target genes for two known and two novel miRNAs showed specific cleavage sites at the 10th and/or 11th nucleotide from the 5′-end of the miRNA corresponding to their miRNA complementary sequences. The findings will lay the foundation for exploring the role of the regulation of miRNAs in response to Cu stress and provide valuable gene information for breeding some Cu-tolerant grapevine cultivars.

description: We construct a dynamic theory of civil conflict hinging on inter-ethnic trust and trade. The model economy is inhabitated by two ethnic groups. Inter-ethnic trade requires imperfectly observed bilateral investments and one group has to form beliefs on the average propensity to trade of the other group. Since conflict disrupts trade, the onset of a conflict signals that the aggressor has a low propensity to trade. Agents observe the history of conflicts and update their beliefs over time, transmitting them to the next generation. The theory bears a set of testable predictions. First, war is a stochastic process whose frequency depends on the state of endogenous beliefs. Second, the probability of future conflicts increases after each conflict episode. Third, "accidental" conflicts that do not reflect economic fundamentals can lead to a permanent breakdown of trust, plunging a society into a vicious cycle of recurrent conflicts (a war trap). The incidence of conflict can be reduced by policies abating cultural barriers, fostering inter-ethnic trade and human capital, and shifting beliefs. Coercive peace policies such as peacekeeping forces or externally imposed regime changes have instead no persistent effects.

description: The mathematical formulation of a large-scale equilibrium natural gas simulation model is presented. Although large-scale natural gas models have been developed and used for energy security and policy analysis quite extensively (e.g., Holz (2007), Egging et al. (2008), Holz et al. (2009) and Lise et al. (2008)), this model differs from earlier ones in its detailed representation of the structure and operations of the Former Soviet Union (FSU) gas sector. In particular, the model represents: (i) market power of transit countries, (ii) transmission pipelines in Russia, Ukraine, Belarus and Central Asia, (iii) differentiation among gas production regions in Russia, and (iv) gas trade relations between FSU countries (e.g., Gazprom’s re-exporting of Central Asian gas). To demonstrate the model, a social benefit-cost analysis of the Nord Stream gas pipeline project from Russia to Germany via the Baltic Sea is provided. It is found that Nord Stream project is profitable for its investors and the project also improves social welfare in all market power scenarios. Also, if transit countries (Ukraine and Belarus) exert substantial market power then the economic value of Nord Stream to its investors and to society improves substantially. We also found that the value of Nord Stream investment is rather sensitive to the degree of downstream competition in European markets and that lack of downstream competition might result in the negative value of the Nord Stream system to Gazprom.

description: We present a study of the static magnetic properties and spin dynamics in Cobalt valence tautomers (VT), molecules where a low-spin (LS) to high-spin (HS) crossover driven by an intramolecular electron transfer can be controlled by the temperature, by the external pressure or by light irradiation. In the investigated complex, a LS-Co(III) ion bound to a dinegative organic ligand can be reversibly converted into the HS-Co(II) bound to a mononegative one. By combining magnetization measurements with Nuclear Magnetic Resonance (NMR) and Muon Spin Relaxation (μSR), we have investigated the static magnetic properties and the spin dynamics as a function of the temperature. Moreover, the effect of the external pressure as well as of the infrared light irradiation have been explored through magnetometry and NMR measurements to determine the spin dynamics of the HS state. The photoinduced HS state, which can have a lifetime of several hours below 30 K, is characterized by spin dynamics in the MHz range, which persist at least down to 10 K. The application of an external pressure causes a progressive increase of the LS-HS crossover, which reaches room temperature for pressures around 10 kbar.

description: We show that drought-induced changes in the intensity of riots lead to moves towards democracy in sub-Saharan Africa, and that these changes are often a result of concessions made as a result of the riots. This provides evidence that low-intensity conflict can have a substantial short-run impact on democratic change, and supports the window of opportunity hypothesis: droughts lead to an increase in the threat of conflict, and incumbents often respond by making democratic concessions.
