description: We describe a model of international, multidimensional policy coordination where countries can enter into selective and separate agreements with di®erent partners along di®erent policy dimensions. The model is used to examine the implications of negotiation tie-in|the requirement that agreements must span multiple dimensions of interaction|for the viability of multilateral cooperation when countries are linked by international trade °ows and transboundary pollution. We show that, while in some cases negotiation tie-in has either no e®ect or can make multilateral cooperation more viable, in others a formal tie-in constraint can make an otherwise viable joint multilateral agreement unstable.

description: In Great Britain the move away from rented accommodation to owner occupation is leaving behind a large group of households with low incomes, wages and hours of work, and high housing costs, who are increasingly in receipt of welfare transfers. The disparity along all of these dimensions between renters and owner occupiers has continued to grow since the 1970’s. The relationship between housing costs, wages and transfer programmes is complex and yet plays an important part in determining the incentive to work for individuals in low income or high housing cost households. While it is true that many individuals who are in these categories are out of the labour force (retired, sick and disabled), there are many who are not and whose incentive to seek work, or to work harder if already in work, could be modified by directly changing the rent levels they face or indirectly via changes to the structure of programmes designed to subsidise housing for the poor. Here we estimate a static discrete choice labour supply model which allows for housing benefit programme participation. We use samples of 42491 married women and 13340 unmarried women drawn from Great Britain Family Resources Surveys 1994/5-97/8. We find that women are quite responsive to labour supply incentives, housing benefit income has similar incentive effects to earned income which suggests any "stigma" is small. Our analysis is complemented by simulating housing benefit and direct rent subsidy reforms.

description: The paper shows the potential of sparsity-based methods in restoring quantized signals. Following up on the study of Brauer et al. (IEEE ICASSP 2016), we significantly extend the range of the evaluation scenarios: we introduce the analysis (cosparse) model, we use more effective algorithms, we experiment with another time-frequency transform. The paper shows that the analysis-based model performs comparably to the synthesis-model, but the Gabor transform produces better results than the originally used cosine transform. Last but not least, we provide codes and data in a reproducible way.

description: The ground-state-to-ground-state $β$-decay $Q$-value of $^{135}\textrm{Cs}(7/2^+)\to\,^{135}\textrm{Ba}(3/2^+)$ was directly measured for the first time utilizing the Phase-Imaging Ion-Cyclotron Resonance (PI-ICR) technique at the JYFLTRAP Penning-trap setup. It is the first direct determination of this $Q$-value and its value of 268.66(30)\,keV is a factor of three more precise than the currently adopted $Q$-value in the Atomic Mass Evaluation 2016. Moreover, the $Q$-value deduced from the $β$-decay endpoint energy has been found to deviate from our result by approximately 6 standard deviations. The measurement confirms that the first-forbidden unique $β^-$-decay transition $^{135}\textrm{Cs}(7/2^+)\to\,^{135}\textrm{Ba}(11/2^-)$ is a candidate for antineutrino-mass measurements with an ultra-low $Q$-value of $0.44(31)$ keV. This $Q$-value is almost an order of magnitude smaller than in any presently running or planned direct (anti)neutrino-mass experiment.

It is shown that the subgroups closed in the function topology on S lie in precisely four equivalence classes under this relation. Which of these classes a closed subgroup G belongs to depends on which of the following statements about pointwise stabilizer subgroups G_{(Γ)} of finite subsets Γ\subseteqΩholds: (i) For every finite set Γ, the subgroup G_{(Γ)} has at least one infinite orbit in Ω. (ii) There exist finite sets Γsuch that all orbits of G_{(Γ)} are finite, but none such that the cardinalities of these orbits have a common finite bound. (iii) There exist finite sets Γsuch that the cardinalities of the orbits of G_{(Γ)} have a common finite bound, but none such that G_{(Γ)}=\{1\}. (iv) There exist finite sets Γsuch that G_{(Γ)}=\{1\}. Some questions for further investigation are discussed.

title: Using Spatio-temporal Feature Type Structures for Coupling Environmental Numerical Models to Each Other and to Data Sources
Creators: name: Harpham, Quillon
Publisher: name: The Open University
Year: 2019

description: The aim of this research is to facilitate the interaction of data between different environmental numerical models and between numerical models and observed data sources, thereby giving rise to more accurate simulations involving a variety of environmental phenomena. The thesis includes ten publications. The first gives an overall context to the field of integrated environmental modelling, which seeks increased interoperability and extensibility between numerical models and data sources. This is followed by a series of four papers introducing and discussing associated enabling technologies: the development of a web portal for the display and comparison of model and in-situ marine data; the FluidEarth 2 implementation of the OpenMI 2.0 standard passing data between models in spatio-temporal structures aggregated from lower level component parts; an extension of the ISO19115 metadata standard to provide aspects related to model coupling; and the Model MAP – a set of necessary concepts for numerical models to be coupled together. These technologies are then applied in a series of papers describing the DRIHM e-Infrastructure for research into hydro-meteorology. These papers focus on the meteorological aspects; the user interface; the back-end computing infrastructures; and two key integrating technologies with an applied example. The final paper gives another example of the use of spatio-temporal feature type structures as part of a new numerical modelling technology. Overall, this series of papers points towards a structured representation of the data supporting environmental numerical models in terms of the underlying spatio-temporal characteristics. This suggests the adoption of a new vocabulary for describing these characteristics. Adoption of this vocabulary and new representation of environmental modelled data will speed the uptake of coupling strategies and create demand for established and new standards to support integrated environmental modelling.

description: The paper studies commuting in Great Britain in the 1990s. The average oneway commute to work is now 38 minutes in London, 33 minutes in the southeast, and 21 minutes in the rest of the country. There are three other findings. First, commuting times are especially long among the highly educated, among home-owners, and among those who work in large plants and offices. In Britain, people with university degrees spend 50% more time travelling to work than those with low qualifications. Private renters do much less commuting than owner-occupiers. Second, there has recently been a rise in commuting times in the south-east and the capital. In our sample, full-time workers in London have lost 70 minutes per week of leisure time to commuting during the course of the 1990s. By contrast, outside the southeast of Britain, there has been no increase in commuting over this decade. In the south-east, 30% of workers now take at least 45 minutes to get to work. In the rest of the country, only 10% do. Third, after controlling for other factors and allowing for the endogeneity of the wage rate, there is a ceteris paribus inverse relationship between commuting hours and hourly pay.
Eigenfunction approach to the persistent random walk in two dimensions

description: The Fourier-Bessel expansion of a function on a circular disc yields a simple series representation for the end-to-end probability distribution function w(R,phi) encountered in a planar persistent random walk, where the direction taken in a step depends on the relative orientation towards the preceding step. For all but the shortest walks, the proposed method provides a rapidly converging, numerically stable algorithm that is particularly useful for the precise study of intermediate-size chains that have not yet approached the diffusion limit. As a practical application, we examine the force-extension diagram of various planar polymer chains. With increasing joint stiffness, a marked transition from rubber-like behaviour to a form of elastic response resembling that of a flexible rod is observed.

description: Previous work on the property rights theory of the …rm suggests that in the presence of outside options, asset ownership may demotivate managers. This paper shows that this conclusion relies on the assumption that a manager’s outside option only depends on her own investment. In many cases, an asset owner has the opportunity to continue with a project even if the team breaks up. The investments of non-owners may then be devalued, but are typically not wholly lost to the owner. This weakens the bargaining power of the non-owner. So, in the presence of cross e¤ects, outside options do not necessarily overturn the property of the original Grossman-HartMoore model that an asset transfer may motivate the gainer and demotivate the loser.

description: The topological approach to baryon-antibaryon production in the chiral phase transition is numerically simulated for rapidly expanding hadronic systems. For that purpose the dynamics of the effective chiral field is implemented on a space - rapidity lattice. The essential features of evolutions from initial 'hot' configurations into final ensembles of (anti-)baryons embedded in the chiral condensate are studied in proper time of comoving frames. Typical times for onset and completion of the roll-down and exponents for the growth of correlations are extracted. Meson and baryon-antibaryon yields are estimated. For standard assumptions about initial coherence lengths they are compatible with experimental results.

description: We propose a formalism to obtain the electroweak sphaleron, which is one of the static classical solutions, using the gradient flow method. By adding a modification term to the gradient flow equation, we can obtain the sphaleron configuration as a stable fixed point of the flow in the large flow time. Applying the method to the $SU(2)$-Higgs model (the Weinberg angle $θ_W$ is $0$) in four dimensions, we obtain the sphaleron configuration whose energy coincides with previous studies numerically. We can also show that the Chern-Simons number of the solution has a half-integer.

description: The spreading of an epidemic is determined by the connectiviy patterns which underlie the population. While it has been noted that a virus spreads more easily on a network in which global distances are small, it remains a great challenge to find approaches that unravel the precise role of local interconnectedness. Such topological properties enter very naturally in the framework of our two-timestep description, also providing a novel approach to tract a probabilistic system. The method is elaborated for SIS-type epidemic processes, leading to a quantitative interpretation of the role of loops up to length 4 in the onset of an epidemic.

description: We investigate theoretically the noise and the full counting statistics of electrons that are emitted from a superconductor into two spatially separated quantum dots by the splitting of Cooper pairs and further on collected in two normal-state electrodes. With negatively-biased drain electrodes and a large superconducting gap, the dynamics of the Cooper pair splitter can be described by a Markovian quantum master equation. Using techniques from full counting statistics, we evaluate the electrical currents, their noise power spectra, and the power-power correlations in the output leads. The current fluctuations can be attributed to the competition between Cooper pair splitting and elastic cotunneling between the quantum dots via the superconductor. In one regime, these processes can be clearly distinguished in the cross-correlation spectrum with peaks and dips appearing at characteristic frequencies associated with elastic cotunneling and Cooper pair splitting, respectively. We corroborate this interpretation by analyzing the charge transport fluctuations in the time domain, specifically by investigating the $g^{(2)}$-function of the output currents. Our work identifies several experimental signatures of the fundamental transport processes involved in Cooper pair splitting and provides specific means to quantify their relative strengths. As such, our results may help guide and interpret future experiments on current fluctuations in Cooper pair splitters.

description: Power indices are general measures of the relative a priori voting power of individual members of a voting body. They are useful for both positive and normative analysis of voting bodies particularly those using weighted voting. This paper applies new algorithms for computing the rival Shapley-Shubik and Banzhaf indices for large voting bodies to shareholder voting power in a cross section of British companies. Each company is a separate voting body and there is much variation in ownership between them resulting in different power structures. Because the data are incomplete, both finite and “oceanic” games of shareholder voting are analysed. The indices are appraised, using reasonable criteria, from the literature on corporate control. The results are unfavourable to the Shapley-Shubik index and suggest that the Banzhaf index much better reflects the variations in the power of shareholders between companies as the weights of shareholder blocs vary.
Temporal Behavior of the Conditional and Gibbs' Entropies

description: We study the temporal approach to equilibrium of the Gibbs' and conditional entropies for both invertible deterministic dynamics as well as non-invertible stochastic systems in the presence of white noise. The conditional entropy will either remain constant or monotonically increase to its maximum of zero. However, the Gibbs' entropy may have a variety of patterns of approach to its final value ranging from a monotone increase or decrease to an oscillatory approach. We have illustrated all of these behaviors using examples in which both entropy dynamics can be determined analytically.

Two CP-violating asymmetries, a linear-polarization asymmetry and a circular-polarization asymmetry, were computed including both non-standard [t t-bar gamma] and [gamma gamma H] couplings. An optimal-observable analysis for the process gamma gamma --> t t-bar --> l^{+-} ... was performed in order to estimate the precision for determination of all relevant non-standard couplings, including the anomalous tbW coupling.

title: The Effect of Grain Size Distribution and Bimodal Sea States on Coarse Beach Sediment Dynamics
Creators: name: Polidoro, Andrea
Publisher: name: The Open University
Year: 2019

description: In this work we investigated the effect of gravel beach profile response under wave spectra characterised by swell and wind wave periods in various combinations. This was done by running an extensive series of 2D physical model tests. It was found that even a small percentage of wave energy within the low frequency range triggers a significant landward displacement of the beach crest. Based on this 2D physical model study, a new parametric model, Shingle B, was derived and an online tool was developed and made available.

 This research also presents a study on the effect of the grain size distribution, i.e. permeability, on the beach profile response. It was investigated, using a permeameter, how a stationary porous flow is influenced by the grain size distribution. The results clearly show that the D15 parameter dominates the flow/resistance behaviour for all the tested samples and the other parameters (D50 or D85) have only second order effects on the flow/resistance relationship.

 Additionally, in order to investigate how the grain size distribution influences both the wave induced pore pressure and beach profile evolution, a 2D physical model study was carried out using ten different gravel beaches. Observations made during this study, in which more complex phenomena were involved, proved that the pore pressure attenuation was mainly influenced by the grading width parameter D85/D15. Measurements on the internal wave set up recorded during these experiments showed that the internal wave set-up was strongly influenced by both the incident wave conditions and the sediment characteristic D50.

 Post-storm beach profiles, with similar grading parameters (e.g., D50, D15 and D85/ D15), were then compared. These comparisons demonstrated that the crest moves upwards and shoreward as D50 and D15 decrease. In particular the crest elevation increases with increasing internal wave set-up.

description: The coherence of collective modes, such as phonons, and their modulation of the electronic states are long sought in complex systems, which is a cross-cutting issue in photovoltaics and quantum electronics. In photovoltaic cells and lasers based on metal halide perovskites, the presence of polaronic coupling, i.e., photocarriers dressed by the macroscopic motion of charged lattice, assisted by terahertz (THz) longitudinal optical (LO) phonons, has been intensely studied yet still debated. This may be key for explaining the remarkable properties of the perovskite materials, e.g., defect tolerance, long charge lifetimes and diffusion length. Here we use the intense single-cycle THz pulse with the peak electric field up to $E_{THz}=$1000\,kV/cm to drive coherent band-edge oscillations at room temperature in CH$_3$NH$_3$PbI$_3$. We reveal the oscillatory behavior dominantly to a specific quantized lattice vibration mode at $ω_{\mathrm{LO}}\sim$4 THz, being both dipole and momentum forbidden. THz-driven coherent dynamics exhibits distinguishing features: the room temperature coherent oscillations at $ω_{\mathrm{LO}}$ longer than 1 ps in both single crystals and thin films; the {\em mode-selective} modulation of different band edge states assisted by electron-phonon ($e$-$ph$) interaction; {\em dynamic mode splitting} controlled by temperature due to entropy and anharmonicity of organic cations. Our results demonstrate intense THz-driven coherent band-edge modulation as a powerful probe of electron-lattice coupling phenomena and provide compelling implications for polaron correlations in perovskites.

description: We characterise profit-maximising operating strategies, over some time horizon [0, T], for an energy store which is trading in an arbitrage market. Our theory allows for leakage, operating inefficiencies and general cost functions. In the special case where the operating cost of a store depends only on its instantaneous power ouput (or input), we present an algorithm to determine the optimal strategies. A key feature is that this algorithm is localised in time, in the sense that the action of the store at a time t ∈ [0, T] only requires information about electricity prices over some subinterval of time [t, τ ] ⊂ [t, T].

description: The German response to the Fukushima nuclear power plant incident was possibly the most significant change of policy towards nuclear power outside Japan, leading to a sudden and very significant shift in the underlying power generation structure in Germany. This provides a very useful natural experiment on the impact of increasing proportions of renewable compared to conventional fuel inputs into power production, helping us to see how changed proportions in future as a result of policy moves in favour of renewables are likely to impact. We find through quasi-experimental exploration of a modified demand-supply framework that despite the swift, unpredicted change, the main impact was a significant increase in prices, partly caused by more frequent situations with unilateral market power. The price impact was also most significant in off-peak hours leading to changed investment incentives. There were no appreciable quantity effects on the market, such as power outages, contrary to some views that the impacts would be significant. Furthermore, we find the sudden and unilateral phase-out decision by the German government has significantly affected electricity prices and thus competitiveness in neighbouring countries.

description: A comparative study of the dynamics of inherent structures at low temperatures is performed on different models of glass formers: a three dimensional Lennard-Jones binary mixture (LJBM), facilitated spin models (either symmetrically constrained, SCIC, or asymmetrically, ACIC) and the trap model. We use suitable correlation functions introduced in a previous work which allow to distinguish the behaviour between models with or without spatial or topological structure. Furthermore, the correlations between inherent structures behave differently in the cases of strong (SCIC) and fragile (ACIC, LJBM) glasses, as a consequence of the different role played by energy barriers when the temperature is lowered. The similarities in the behaviour of the ACIC and LJBM suggest a common nature of the glassy dynamics for both systems.

description: The X-ray emission from a supernova remnant (SNR) is a powerful diagnostic of the state of the shocked plasma. The temperature (kT) and the emission measure (EM) of the shocked-gas are related to the energy of the explosion, the age of the SNR, and the density of the surrounding medium. Progress in X-ray observations of SNRs has resulted in a significant sample of Galactic SNRs with measured kT and EM values. We apply spherically symmetric SNR evolution models to a new set of 43 SNRs to estimate ages, explosion energies, and circumstellar medium densities. The distribution of ages yields a SNR birth rate. The energies and densities are well fit with log-normal distributions, with wide dispersions. SNRs with two emission components are used to distinguish between SNR models with uniform ISM and with stellar wind environment. We find type Ia SNRs to be consistent with a stellar wind environment. Inclusion of stellar wind SNR models has a significant effect on estimated lifetimes and explosion energies of SNRs. This reduces the discrepancy between the estimated SNR birthrate and the SN rate of the Galaxy.

description: The orbital period ratios of neighbouring sub-Neptunes are distributed asymmetrically near first-order resonances. There are deficits of systems---"troughs" in the period ratio histogram---just short of commensurability, and excesses---"peaks"---just wide of it. We reproduce quantitatively the strongest peak-trough asymmetries, near the 3:2 and 2:1 resonances, using dissipative interactions between planets and their natal discs. Disc eccentricity damping captures bodies into resonance and clears the trough, and when combined with disc-driven convergent migration, draws planets initially wide of commensurability into the peak. The migration implied by the magnitude of the peak is modest; reductions in orbital period are $\sim$10\%, supporting the view that sub-Neptunes complete their formation more-or-less in situ. Once captured into resonance, sub-Neptunes of typical mass $\sim$$5$--$15 M_{\oplus}$ stay captured (contrary to an earlier claim), as they are immune to the overstability that afflicts lower mass planets. Driving the limited, short-scale migration is a gas disc depleted in mass relative to a solar-composition disc by 3--5 orders of magnitude. Such gas-poor but not gas-empty environments are quantitatively consistent with sub-Neptune core formation by giant impacts (and not, e.g., pebble accretion). While disc-planet interactions at the close of the planet formation era adequately explain the 3:2 and 2:1 asymmetries at periods $\gtrsim$ $5$--$15$ days, subsequent modification by stellar tides appears necessary at shorter periods, particularly for the 2:1.

Effects of Dense Quark Matter on Gluon Propagators in Lattice QC$_2$D

description: The transverse and longitudinal gluon propagators in the Landau gauge are studied in the two-color lattice QCD at nonzero quark chemical potential $μ_q$. Parameterization of the momentum dependence of the propagators is provided for all values of chemical potential under study. We find that the longitudinal propagator is infrared suppressed at nonzero $μ_q$ with suppression increasing with increasing $μ_q$. The transverse propagator dependence on $μ_q$ was found to be opposite: it is enhanced at large $μ_q$. It is found, respectively, that the electric screening mass is increasing while the magnetic screening mass is decreasing with increasing $μ_q$. Nice agreement between the electric screening mass computed from the longitudinal propagator and the Debye mass computed earlier from the singlet static quark-antiquark potential was found. We discuss how the dependence of the propagators on the chemical potential correlates with the respective dependence of the string tension. Additionally, we consider the difference between two propagators as a function of the momentum and make interesting observations.

description: Using spectroscopic data from the Deep Extragalactic Evolutionary Probe (DEEP) Groth Strip survey (DGSS), we analyze the gas-phase oxygen abundances in the warm ionized medium for 64 emission-line field galaxies in the redshift range 0.26-19) end of the sample and vanishingly small for objects at the high-luminosity end of the sample (M_B ~ -22). Simple galaxy evolution models can produce reasonable agreement with observations for low-mass galaxies when least two of the following are true: 1) low-mass galaxies have lower effective chemical yields than massive galaxies, 2) low-mass galaxies assemble on longer timescales than massive galaxies, 3) low-mass galaxies began the assembly process at a later epoch than massive galaxies.

description: Objective : Although human aging is characterized by loss of fertility and progressive decline in physical abilities, later life is associated with better psychological health and well-being. Furthermore, there has been an unprecedented increase in average lifespan over the past century without corresponding extensions of fertile and healthy age spans. We propose a possible explanation for these paradoxical phenomena. Method: We reviewed the relevant literature on aging, well-being, and wisdom. Results: An increase in specific components of individual wisdom in later life may make up for the loss of fertility as well as declining physical health. However, current data on the relationship between aging and individual wisdom are not consistent, and do not explain increased longevity in the general population during the past century. We propose that greater societal wisdom (including compassion) may account for the notable increase in average lifespan over the last century. Data in older adults with serious mental illnesses are limited, but suggest that many of them too experience improved psychosocial functioning, although their longevity has not yet increased, suggesting persistent stigma against mental illness and inadequate societal compassion. Conclusions: Research should focus on the reasons for discrepant findings related to ageassociated changes in different components of individual wisdom; also, more work is needed on the construct of societal wisdom. Studies of wisdom and well-being are warranted in older people with serious mental illnesses, along with campaigns to enhance societal compassion for these disenfranchised individuals. Finally, effective interventions to enhance wisdom need to be developed and tested.

description: Cooperating behavior may be fostered by personality traits reflecting either favorable inclination to others or willingness to comply with norms and rules. We test the relative importance of these two factors in an experiment where subjects provide real mental effort in two treatments with identical task, differing only by whether others’ payment is affected. If the first hypothesis is true, subjects reporting high Agreeableness score should put more effort; if the second is true, reporting higher Conscientiousness should predict more effort. We find experimental support for the second hypothesis but not for the first, as subjects reporting high Altruism do not behave consistently with this statement.

description: We show that a firm’s profits under Cournot oligopoly can be increasing in the number of firms in the industry if wages are determined by decentralised bargaining in unionised bilateral oligopoly. The intuition for the result is that increased product market competition following an increase in the number of firms is mirrored by increased labour market rivalry which induces (profit-enhancing) wage moderation. Whether the product or labour market effect dominates depends both on the extent of union bargaining power and on the nature of union preferences. An incumbent monopolist will have an incentive to accommodate entry if the labour market effect dominates. We also show that this incentive is stronger if the incumbent anticipates that, post entry, it will be able to act as a Stackelberg leader.
