description: We introduce and study a metapopulation model of random walkers interacting at the nodes of a complex network. The model integrates random relocation moves over the links of the network with local interactions depending on the node occupation probabilities. The model is highly versatile, as the motion of the walkers can be fed on topological properties of the nodes, such as their degree, while any general nonlinear function of the occupation probability of a node can be considered as local reaction term. In addition to this, the relative strength of reaction and relocation can be tuned at will, depending on the specific application being examined. We derive an analytical expression for the occupation probability of the walkers at equilibrium in the most general case. We show that it depends on different order derivatives of the local reaction functions and not only on the degree of a node, but also on the average degree of its neighbours at various distances. For such a reason, reactive random walkers are very sensitive to the structure of a network and are a powerful way to detect network properties such as symmetries or degree-degree correlations. As possible applications, we first discuss how the occupation probability of reactive random walkers can be used to define novel measures of functional centrality for the nodes of a network. We then illustrate how network components with the same symmetries can be revealed by tracking the evolution of reactive walkers. Finally, we show that the dynamics of our model is influenced by the presence of degree-degree correlations, so that assortative and disassortative networks can be classified by quantitative indicators based on reactive walkers.
Long distance contribution to $B^- \to K^- K^- π^+$, - a searching ground mode for new physics

description: The decay $B^- \to K^- K^- π^+$ has been sugested as a test for minimal supersymmetric standard model and for supersymmetric models with R-parity violating couplings, in view of its extreme smallnesss in the standard model. We calculate two long distance contributions to this decay, that associated with $DD$ and $Dπ$ intermediate states and that induced by virtual $D$, $π$ mesons. The branching ratio due to these contributions is $6 \times 10^{-12}$, which is somewhat smaller than the standard model short distance result, leaving this decay free for the search of new physics.

Estimating Marginal Cost of Quality Improvements: The Case of the UK Electricity Distribution Companies

description: The main aim of this paper is to develop an econometric approach to estimation of marginal costs of improving quality of service. We implement this methodology by way of applying it to the case of the UK electricity distribution networks. The estimated marginal costs allow us to shed light on the effectiveness of the current UK incentive regulation to improve quality, and to derive optimal quality levels and welfare losses due to sub-optimal quality levels. The proposed method also allows us to measure the welfare effect of the observed quality improvements in the UK between 1995 and 2003. Our results suggest that while the incentive schemes established by the regulator to encourage utilities to reduce network energy losses leads to improvement in sector performance, they do not provide utilities with sufficient incentives to avoid power interruptions. We find that the observed improvements in quality during the period of this study only represented 30% of the potential customer welfare gains, and hence there was still significant scope for quality improvements.

description: Aim: BCRP plays a major role in the efflux of cytotoxic molecules, limiting their antiproliferative activity. We aimed to design and synthesize new BCRP inhibitors to render cancerous tumors more sensitive toward anticancer agents. Materials & methods: Based on our previous work, we conceived potential BCRP inhibitors derived from 1,3,4-oxadiazoles bearing two substituted phenyl rings. Results: Evaluating 19 derivatives, we found that 2,5-diaryl-1,3,4-oxadiazoles possessing methoxy groups were the most active. The highest activity was recorded with derivatives bearing three methoxy groups. The most active compound (3j) was selective in inhibiting BCRP and nontoxic as evidenced by cellular tests. Conclusion: 3j is a promising BCRP inhibitor thanks to its synthetic accessibility and biological profile. Substituted oxadiazoles were investigated as inhibitors of BCRP. The most active inhibitors can be synthesized in one step with acceptable yields. The most active compound (3j) strongly inhibited BCRP (ABCG2) with no toxicity even at high concentrations. 3j is specific to BCRP compared with P-gp and MRP1. 3j showed higher solubility in water than the most potent inhibitors reported so far.

description: We study Downsian competition in a Mirrleesian model of income taxation. The competing politicians may differ in competence. If politicians engage in vote-share maximization, the less competent politician's policy proposals are attractive to the minority of rich agents, whereas those of the competent politician are attractive to the majority of poor agents. The less competent politician wins with positive probability, which gives rise to a political failure in the sense of Besley and Coate (1998). Political failures are avoided if politicians maximize winning probabilities. Nevertheless, the two equilibria cannot be Pareto-ranked, the minority may be better o under vote-share maximization.

description: The construction of large-scale quantum computers will require modular architectures that allow physical resources to be localized in easy-to-manage packages. In this work, we examine the impact of different graph structures on the preparation of entangled states. We begin by explaining a formal framework, the hierarchical product, in which modular graphs can be easily constructed. This framework naturally leads us to suggest a class of graphs, which we dub hierarchies. We argue that such graphs have favorable properties for quantum information processing, such as a small diameter and small total edge weight, and use the concept of Pareto efficiency to identify promising quantum graph architectures. We present numerical and analytical results on the speed at which large entangled states can be created on nearest-neighbor grids and hierarchy graphs. We also present a scheme for performing circuit placement--the translation from circuit diagrams to machine qubits--on quantum systems whose connectivity is described by hierarchies.

description: Algorithm, based on explicit representations for analytic continuation of the T-matrix Faddeev components on unphysical sheets, is worked out for calculations of resonances in the three-body quantum problem. According to the representations, poles of the T--matrix, scattering matrix and resolvent on unphysical sheets, interpreted as resonances, coincide with those complex energy values where appropriate truncations of the scattering matrix have zero as eigenvalue. Scattering amplitudes on the physical sheet, necessary to construct scattering matrix, are calculated on the basis of the Faddeev differential equations. Effectiveness of the algorithm developed is demonstrated for example of searching for resonances in the system $nnp$ and in a model three-boson system.

description: Assuming that the lightest supersymmetric particle (LSP) is the lightest neutralino, we present a detailed exploration of neutralino-stau coannihilation channels, including analytical expressions and numerical results. We also include neutralino coannihilations with the selectron and smuon. We evaluate the implications of coannihilations for the cosmological relic density of the LSP, which is assumed to be stable, in the constrained minimal supersymmetric extension of the Standard Model (CMSSM), in which the soft supersymmetry-breaking parameters are universal at the supergravity GUT scale. We evaluate the changes due to coannihilations in the region of the MSSM parameter space that is consistent with the cosmological upper limit on the relic LSP density. In particular, we find that the upper limit on the mass of the neutralino is increased from about 200 GeV to about 600 GeV in the CMSSM, and estimate a qualitatively similar increase for gauginos in the general MSSM.

description: Aim: To synthesize novel chloroquine analogues and evaluate them for antimicrobial and cytotoxic potential. Methods: Novel analogues were synthesized from chloroquine by nucleophilic substitution reaction at the 4-amino position. Results: Analogue CS1 showed maximum antimicrobial potential (30.3 ± 0.15 mm zone) against Pseudomonas aeruginosa and produced a 19.2 ± 0.21 mm zone against Candida albicans, while CS0 produced no zone at the same concentration. Analogue CS9 has excellent cytotoxic potential (HeLa cell line), showing 100% inhibition (IC50 = 8.9 ± 1.2 μg/ml), compared with CS0 (61.9% inhibition at 30 μg/ml). Conclusion: These synthesized chloroquine analogues have excellent activity against different microbial strains and cervical cancer cell lines (HeLa) compared with their parent molecule. Novel chloroquine analogues were synthesized by nucleophilic substitution reaction at the 4-amino position. These analogues were characterized using nuclear magnetic resonance and Fourier transform infrared spectroscopic techniques. The antimicrobial result showed that the new analogues have good antimicrobial activity, while chloroquine was not active against any strain. In the cytotoxicity study, a few analogues had improved activity compared with chloroquine. Docking results also support in vitro findings due to good binding affinity.
The X-ray catalog of spectroscopically identified Galactic O stars: Investigating the dependence of X-ray luminosity on stellar and wind parameters

description: The X-ray emission of O-type stars was first discovered in the early days of the Einstein satellite. Since then many different surveys have confirmed that the ratio of X-ray to bolometric luminosity in O-type stars is roughly constant, but there is a paucity of studies that account for detailed information on spectral and wind properties of O-stars. Recently a significant sample of O stars within our Galaxy was spectroscopically identified and presented in the Galactic O-Star Spectroscopic Survey (GOSS). At the same time, a large high-fidelity catalog of X-ray sources detected by the XMM-Newton X-ray telescope was released. Here we present the X-ray catalog of O stars with known spectral types and investigate the dependence of their X-ray properties on spectral type as well as stellar and wind parameters. We find that, among the GOSS sample, 127 O-stars have a unique XMM-Newton source counterpart and a Gaia data release 2 (DR2) association. Terminal velocities are known for a subsample of 35 of these stars. We confirm that the X-ray luminosities of dwarf and giant O stars correlate with their bolometric luminosity. For the subsample of O stars with measure terminal velocities we find that the X-ray luminosities of dwarf and giant O stars also correlate with wind parameters. However, we find that these correlations break down for supergiant stars. Moreover, we show that supergiant stars are systematically harder in X-rays compared to giant and dwarf O-type stars. We find that the X-ray luminosity depends on spectral type, but seems to be independent of whether the stars are single or in a binary system. Finally, we show that the distribution of log(Lx/Lbol) in our sample stars is non-Gaussian, with the peak of the distribution at log(Lx/Lbol) around -6.6.

description: NGO aid is still widely believed to be superior to official aid (ODA). However, the incentives of NGOs to excel and target aid to the poor and deserving are increasingly disputed. We contribute to the emerging literature on the allocation of NGO aid by performing panel Tobit estimations for Swiss NGOs. The analysis offers new insights in two major regards: First, we cover the allocation of both self-financed and officially co-financed aid for a large panel of NGOs and recipient countries. Second, by classifying each NGO according to its financing structure, we address the unresolved question of whether financial dependence on the government impairs the targeting of NGO aid. It turns out that NGOs mimic the state as well as NGO peers. Officially refinanced NGOs are more inclined to imitate the allocation of ODA. However, the degree of financial dependence does not affect the poverty orientation of NGO aid and the incentives of NGOs to engage in easier environments. The allocation of self-financed aid differs in several respects from the allocation of officially co-financed aid, including the role of financial dependence for imitating the state and herding among NGOs.
Deformations of Lorentzian Polyhedra: Kapovich-Millson phase space and SU(1,1) Intertwiners

description: We describe the Lorentzian version of the Kapovitch-Millson phase space for polyhedra with $N$ faces. Starting with the Schwinger representation of the $\mathfrak{su}(1,1)$ Lie algebra in terms of a pair of complex variables (or spinor), we define the phase space for a space-like vectors in the three-dimensional Minkowski space $\mathbb{R}^{1,2}$. Considering $N$ copies of this space, quotiented by a closure constraint forcing the sum of those 3-vectors to vanish, we obtain the phase space for Lorentzian polyhedra with $N$ faces whose normal vectors are space-like, up to Lorentz transformations. We identify a generating set of $SU(1,1)$-invariant observables, whose flow by the Poisson bracket generate both area-preserving and area-changing deformations. We further show that the area-preserving observables form a $\mathfrak{gl}_{N}(\mathbb{R})$ Lie algebra and that they generate a $GL_{N}(\mathbb{R})$ action on Lorentzian polyhedra at fixed total area. That action is cyclic and all Lorentzian polyhedra can be obtained from a totally squashed polyhedron (with only two non-trivial faces) by a $GL_{N}(\mathbb{R})$ transformation. All those features carry on to the quantum level, where quantum Lorentzian polyhedra are defined as $SU(1,1)$ intertwiners between unitary $SU(1,1)$-representations from the principal continuous series. Those $SU(1,1)$-intertwiners are the building blocks of spin network states in loop quantum gravity in 3+1 dimensions for time-like slicing and the present analysis applies to deformations of the quantum geometry of time-like boundaries in quantum gravity, which is especially relevant to the study of quasi-local observables and holographic duality.

description: A unique field experiment in South Africa has provided the opportunity to study the Critically Endangered African penguin Spheniscus demersus and their prey with and without localised fishing activity. The aim of this experiment was to understand the impact of the local purse-seine fishery on the penguin population declines. This PhD uses a long-term biologging dataset to determine whether fishing results in changes in prey acquisition in the African penguin. I quantify the level of overlap between the purse-seine fishery and the foraging grounds of the penguins and found that overlap was lowest when prey biomass was low, suggesting that competition with the fishery is exacerbated when conditions are poor. I then investigated how the presence of the fishery may result in changes in penguin foraging and prey schooling behaviour using simultaneous prey acoustic surveys with penguin biologging data. Schools were smaller in height and length, and penguins carried out 10% fewer foraging dives when the fishery was present. Consequently, fishing intensity, particularly when the fishery was harvesting sardine, was found to impact penguin foraging effort. Acceleration data also suggested more foraging behaviour occurs when prey biomass is high. Finally, a bioenergetics model was developed to determine the proportion of breeding penguins that are returning from a foraging trip with sufficient energy to successfully rear chicks. Breeding penguins were found to be at their energetic limit with only 50% of individuals expecting to return from foraging trips in an energy surplus. Through simulating a reduction in fishing, the median net energy increased by over 1000 kJ and a further 12% of individuals were in an energy surplus after the 2-day period. This thesis highlights the effects of fishing on the foraging behaviour of the Critically Endangered African penguin. Fishing and changes in prey availability significantly impacted the amount of foraging behaviour carried out by penguins.

description: We demonstrate low-power amplification process in cavity optomechanics (COM). This operation is based on the nonlinear position-modulated self-Kerr interaction. Owing to this nonlinear term, the effective coupling highly scales with the photon number, resulting in a giant enhancement of the cooperativity. Even for small nonlinearity, the system reaches the amplification threshold for weak driving strength, leading to low-power phonon lasing. This amplifier can be phase-preserving and provides a practical advantage related to the power consumption issues. This work opens up new avenues to realize low-power and efficient amplifiers in optomechanics and related fields.

description: We give a physical interpretation of the entries of the reflection $K$-matrices of Baxter's eight-vertex model in terms of an Ising interaction at an open boundary. Although the model still defies an exact solution we nevertheless obtain the exact surface free energy from a crossing-unitarity relation. The singular part of the surface energy is described by the critical exponents $α_s = 2 - \fracπ{2μ}$ and $α_1 = 1 - \fracπμ$, where $μ$ controls the strength of the four-spin interaction. These values reduce to the known Ising exponents at the decoupling point $μ=π/2$ and confirm the scaling relations $α_s = α_b + ν$ and $α_1 = α_b -1$.

description: This paper provides a rationale for group support for political violence in situations where violence does not provide a material benefit. Rabin’s (1993) theory of fairness is adopted to demonstrate that although group violence may not be the equilibrium of a material game it may be a fairness equilibrium in a game containing psychological payoffs. For this to happen the material stakes must be perceived as low and psychological payoffs are expressive. Although the material stakes are actually high, members of each group may choose expressively to support the use of violence because the probability of being decisive is low. The paper also considers the possibility of peace emerging as a fairness equilibrium. This can only happen if each group perceives the other as making some sacrifice in choosing peace.

description: The Chinese government frequently threatens that meetings between its trading partners’ officials and the Dalai Lama will be met with animosity and ultimately harm trade ties with China. We run a gravity model of exports to China from 159 partner countries between 1991 and 2008 to test to which extent bilateral tensions affect trade with autocratic China. In order to account for the potential endogeneity of meetings with the Dalai Lama, the number of Tibet Support Groups and the travel pattern of the Tibetan leader are used as instruments. Our empirical results support the idea that countries officially receiving the Dalai Lama at the highest political level are punished through a reduction of their exports to China. However, this ‘Dalai Lama Effect’ is only observed for the Hu Jintao era and not for earlier periods. Furthermore, we find that this effect is mainly driven by reduced exports of machinery and transport equipment and that it disappears two years after a meeting took place.

description: This paper tests the hypothesis that the extension of the voting franchise was caused by the threat of revolution, as suggested by Acemoglu and Robinson [Quarterly Journal of Economics 115, 1167-1199, 2000]. We approximate the threat of revolution in a given country by revolutionary events happening in neighboring countries. We investigate the relationship between this new measure of the threat of revolution and measures of su¤rage reform in two samples of European countries covering the period from 1820 to 1938. We ?nd strong support for the 'threat of revolution theory'. We also ?nd some evidence that war triggered suffrage reform, whereas other theories of the extension of the franchise, including 'modernization theory', receive little support.

The model is used to analyse the implications of changing from a title based division of property on divorce to an equal sharing regime. There are two opposing effects. In line with popular expectations, the change to an equal sharing regime prevents some wealthy individuals from marrying since they risk losing half of their assets in the event of divorce. Offsetting this, the equal sharing property division regime enables cooperative investments to be made in marriage, and so increases the value of marriage relative to cohabitation for some couples. Overall the impact on the marriage rate is ambiguous, although the rate is most likely to increase where it is more difficult to make cooperative investments due to unilateral divorce laws, and where couples are more similar to each other, reducing their cost of divorce.

description: 4-derivative gravity provides a renormalizable theory of quantum gravity at the price of introducing a physical ghost, which could admit a sensible positive-energy quantization. To understand its physics, we compute ghost-mediated scatterings among matter particles at tree-level, finding a new power-like infra-red enhancement typical of 4-derivative theories, that we dub '$ghostrahlung$'. Super-Planckian scatterings get downgraded to Planckian by radiating hard gravitons and ghosts, which are weakly coupled and carry away the energy.

Energy-efficiency and environmental policies & income supplements in the UK: Their evolution and distributional impact in relation to domestic energy bills

description: The paper examines the financial costs of energy-efficiency and environmental policies that directly affect domestic electricity and gas bills in the UK over time. It also attempts for the first time to work out the current distributional impacts of these policies and others that act as income supplements thereby presenting a consistent picture across time and income deciles. Figures suggest that during 2000-11, the percentage share of policy costs in typical domestic electricity and gas bills rose by 14% and 4%, respectively. This reflects a growing share of policy costs in bills which is relatively small for gas customers but significant for electricity customers. Moreover, distributional impacts of the energy-policy mix highlight the issue of imperfect targeting of low-income households during 2009-10. The study also indicates that during 2010-11, 76% of the funds for energy-efficiency schemes were handled by the private sector. Given that a long-term solution to fuel poverty lies in improving thermal efficiency of houses; this research draws attention towards the need for definitive evidence on the ways in which energy suppliers charge policy costs from their domestic customers. This would facilitate in making the future policies more empirically grounded. In time, a clearer understanding of official statistics on energy bills will go a long way in restoring consumers’ trust in the pricing mechanism of the energy market.

description: An unobserved components model in which the signal is buried in noise that is non-Gaussian may throw up observations that, when judged by the Gaussian yardstick, are outliers. We describe an observation driven model, based on a conditional Student t-distribution, that is tractable and retains some of the desirable features of the linear Gaussian model. Letting the dynamics be driven by the score of the conditional distribution leads to a specification that is not only easy to implement, but which also facilitates the development of a comprehensive and relatively straightforward theory for the asymptotic distribution of the ML estimator. The methods are illustrated with an application to rail travel in the UK. The .final part of the article shows how the model may be extended to include explanatory variables.

Fermi and Gamow-Teller Strength in Charge Exchange with Radioactive Beams

description: At forward angles, and bombarding energies E > 200 MeV, the (p,n) and (n,p) reactions are thought to be directly proportional to the Gamow-Teller transition strengths in the nuclei. Assuming that this relationship also holds for charge exchange induced by high-energy heavy ions, it would be very useful in studies with radioactive beams. Contrary to this expectation, we show that the determination of Gamow-Teller and Fermi matrix elements from heavy-ion charge-exchange at forward angles is very inaccurate.

Reexamination of the Constraint on Topcolor-Assisted Technicolor Models from R_b

description: Recent study on the charged top-pion correction to R_b shows that it is negative and large, so that the precision experimental value of R_b gives rise to a severe constraint on the topcolor-assisted technicolor models such that the top-pion mass should be of the order of 1 TeV. In this paper, we restudy this constraint by further taking account the extended technicolor gauge boson correction which is positive. With this positive contribution to R_b, the constraint on the topcolor-assisted technicolor models from R_b changes significantly. The top-pion mass is allowed to be in the region of a few hundred GeV depending on the models.

description: Multiple-input-multiple-output (MIMO) antenna will play a key role in the development of fifth generation (5G) wireless mobile communication systems due to their performance-enhancement capability in multipath environment. Antenna radiation efficiency is an important parameter for MIMO antenna system. In this paper, we present a comparison of MIMO antenna efficiency measurements performed in Anechoic Chamber (AC) and Reverberation Chamber (RC) at the UK National Physical Laboratory. Two commercial available directional dual polarized full LTE band MIMO antennas were measured both in AC and RC between 1 GHz and 3 GHz.

description: We study the end-point of the Electroweak phase transition using the auxiliary mass method. The end point is $m_H\sim40$ (GeV) in the case $m_t=0$ (GeV) and strongly depends on the top quark mass. A first order phase transition disappears at $m_t\sim 160$ (GeV). The renormalization effect of the top quark is significant.

International benchmarking of Electricity Transmission by Regulators: Theory and Practice

description: Benchmarking of electricity networks has a key role in sharing the benefits of efficiency improvements with consumers and ensuring regulated companies earn a fair return on their investments. This paper analyses the theory and practice of international benchmarking of electricity transmission by regulators. We examine the literature relevant to electricity transmission benchmarking and conduct a survey of 48 national electricity regulators. Consideration of the literature and our survey indicates that electricity transmission benchmarking is significantly more challenging than electricity distribution benchmarking. New panel data techniques aimed at dealing with unobserved heterogeneity and the validity of the comparator group look intellectually promising but are in their infancy for regulatory purposes. In electricity transmission choosing variables is particularly difficult, because of the large number of potential variables to choose from. Failure to apply benchmarking appropriately may negatively affect investors’ willingness to invest in the future. While few of our surveyed regulators acknowledge that regulatory risk is currently an issue in transmission benchmarking, many more concede it might be. New regulatory approaches – such as those based on tendering, negotiated settlements, a wider range of outputs or longer term grid planning - are emerging and will necessarily involve a reduced role for benchmarking.

description: We have updated our multipole analyses to incorporate new data from the low-energy and delta resonance regions. We note a slight decrease in our estimate of the delta photo-decay amplitudes. This agrees with results found in Compton scattering. Our values are also in good agreement with a previous RPI determination. We have reexamined our determinations of the E2/M1 ratio at the resonance energy and at the pole. We find an E2/M1 ratio (at the pole) which is in good agreement with recent the Mainz value.

Persistent Habits, optimal Monetary Policy Inertia and Interest Rate Smoothing

Subjects: Multiplicative habits

description: Dynamic stochastic general equilibrium models featuring imperfect competition and nominal rigidities have become central for the analysis of the monetary transmission mechanism and for understanding the conduct of monetary policy. However, it is agreed that the benchmark model fails to generate the persistence of output and inflation that is observed in the data. Moreover, it cannot provide a theoretically well-grounded justification for the interest rate smoothing behaviour of monetary authorities. This paper attempts to overcome these deficiencies by embedding a multiplicative habit specification in a New Keynesian model. We show that this particular form of habit formation can explain why monetary authorities smooth interest rates.

description: Few level quantum systems driven by $n_\mathrm{f}$ incommensurate fundamental frequencies exhibit temporal analogues of non-interacting phenomena in $n_\mathrm{f}$ spatial dimensions, a consequence of the generalisation of Floquet theory in frequency space. We organise the fundamental solutions of the frequency lattice model for $n_\mathrm{f}=2$ into a quasi-energy band structure and show that every band is classified by an integer Chern number. In the trivial class, all bands have zero Chern number and the quasi-periodic dynamics is qualitatively similar to Floquet dynamics. The topological class with non-zero Chern bands has dramatic dynamical signatures, including the pumping of energy from one drive to the other, chaotic sensitivity to initial conditions, and aperiodic time dynamics of expectation values. The topological class is however unstable to generic perturbations due to exact level crossings in the quasi-energy spectrum. Nevertheless, using the case study of a spin in a quasi-periodically varying magnetic field, we show that topological class can be realised at low frequencies as a pre-thermal phase, and at finite frequencies using counter-diabatic tools.
