description: We discuss the application of the momentum-shell renormalization group method to the interacting homogeneous Bose gas in the symmetric and in the symmetry-broken phases. It is demonstrated that recently discussed discrepancies are artifacts of not taking proper care of infrared divergencies appearing at finite temperature. If these divergencies are taken into account and treated properly by means of the epsilon-expansion, the resulting renormalization group equations and the corresponding universal properties are identical in the symmetric and the symmetry-broken phases.

description: In-line holographic microscopy provides an unparalleled wealth of information about the properties of colloidal dispersions. Analyzing one colloidal particle's hologram with the Lorenz-Mie theory of light scattering yields the particle's three-dimensional position with nanometer precision while simultaneously reporting its size and refractive index with part-per-thousand resolution. Analyzing a few thousand holograms in this way provides a comprehensive picture of the particles that make up a dispersion, even for complex multicomponent systems. All of this valuable information comes at the cost of three computationally expensive steps: (1) identifying and localizing features of interest within recorded holograms, (2) estimating each particle's properties based on characteristics of the associated features, and finally (3) optimizing those estimates through pixel-by-pixel fits to a generative model. Here, we demonstrate an end-to-end implementation that is based entirely on machine-learning techniques. Characterizing and Tracking Colloids Holographically (CATCH) with deep convolutional neural networks is fast enough for real-time applications and otherwise outperforms conventional analytical algorithms, particularly for heterogeneous and crowded samples. We demonstrate this system's capabilities with experiments on free-flowing and holographically trapped colloidal spheres.

Reforming IMF and World Bank governance : in search of simplicity, transparency and democratic legitimacy in the voting rules

description: We discuss the reform of the voting rules at the heart of the governance of the IMF and World Bank (the BWIs) in terms of three principles that we suggest ought to be fundamental: simplicity, transparency and democratic legitimacy. By simplicity we mean that the rules should make sense in terms of the purposes of the BWI and be easy to understand. By transparency we mean that the rules mean what they appear to mean in the sense of leading to the same distribution of voting power as the institution’s designers intended. We show using voting power analysis that the inequality in the distribution of voting power among countries is greater than that of their voting weight. By democratic legitimacy, we consider whether we can reconcile weighted voting with democracy. Our conclusion is that the voting rules as they currently exist are far from satisfying any of these criteria and that recent reform proposals do not lead us to change this conclusion.
Reconciling the Light Scalar Mesons with Breit-Wigner Resonances as well as the Quark Model

description: Resonances appearing in hadronic scattering processes are described by a two-phase model. In the one phase, scattering products are observed, whereas the other phase describes confinement. A so-called ``Resonance-Spectrum Expansion'' is derived, containing expressions that resemble Breit-Wigner formulae. This method also provides a straightforward explanation for the origin of the light scalar mesons without requiring extra degrees of freedom.

description: This paper explores the relationship between domestic retail electricity prices in Great Britain and their determinants in the particular context of the New Electricity Trading Arrangements (NETA) introduced in 2001. The analysis requires a consistent comparison of wholesale power price series before and after NETA, which we investigate using a range of wholesale future price series. Despite its stated intention of reducing prices, we conclude that the net effect of NETA alongside other developments instead merely rearranged where money was made in the system.
A class of self-gravitating, magnetized accretion disks

description: The steady-state structure of self-gravitating, magnetized accretion disks is studied using a set of self-similar solutions which are appropriate in the outer regions. The disk is assumed to be isothermal and the magnetic field outside of the disk is treated in a phenomenological way. However, the internal field is determined self-consistently. The behaviour of the solutions are investigated by changing the input parameters of the model, i.e. mass accretion rate, coefficients of viscosity and resistivity, and the magnetic field configuration.

We show that, in contrast to conventional superconductors, MgB$_2$ is characterized by two different anisotropy parameters ($Γ_λ= λ_c/λ_{ab}$ and $Γ_ξ= ξ_{ab}/ξ_c$) which strongly differ at low temperature and merge at $T_c $. These results are in very good agreement with recent calculations in weakly coupled two bands suprerconductors (Phys. Rev. B, 66, 020509(R) (2002).

Perturbative approach to the colour confinement, both in gluodynamics and the real world, was long considered heretic but is gaining ground. We discuss Gribov's approach to the confinement problem, centered around the role played by light quarks - the supercritical light quark confinement scenario. We also review some recent developments that are motivated, directly or indirectly, by his ideas.

description: We explore the scope of employing standard assumptions and replicating standard (KuhnTucker-type) techniques that are used to study the first-best Pareto frontier to the study of Pareto frontiers of second-best economies. In the context of a simple second-best situation created by the inability of the government to implement personalized lump-sum transfers and where the government takes recourse to linear (Ramsey) commodity taxes as alternative redistributive devices, we identify at least three potential problems that second-best situations create for obtaining well-behaved Pareto frontiers. We show that additional conditions are required to ensure that the second-best Pareto frontier of an economy with H consumers will have the expected structure of a H −1-dimensional manifold. Second-best Pareto optima, as is well-known, are characterized by consumption and/ or production inefficiencies. In a class of private-ownership economies with Ramsey taxation, we show that, generically, while the jointly production and consumption inefficient component of the second-best Pareto manifold is a submanifold that also has a dimension equal to H − 1, the production efficient but consumption inefficient, consumption effi- cient but production inefficient, and the first-best components are lower dimensional, and hence negligible in size, submanifolds. Thus, we formally demonstrate that, generically, in second-best economies, joint production and consumption inefficiencies are prevalent and, hence, neither producer nor consumer prices reveal the true social shadow prices of resources. The recovery of unobservable shadow prices from observable data is crucial for cost-benefit analysis of competing public sector projects. Our results demonstrate the important need for further research for recovering the true social shadow prices from observable data in second-best economies.

description: We are working towards filling the last remaining gap in the historical national accounts of Russia and the USSR in the twentieth century. The gap includes the Great War (1914 to 1917), the Bolshevik Revolution, the Civil War and War Communism (1918 to 1921), and postwar recovery under the New Economic Policy of a mixed economy (1921 to 1928). Our work builds on our predecessors and also returns to a number of original sources. We find that the economic performance of the Russian Empire in wartime was somewhat better than previously thought; that of War Communism was correspondingly worse. We confirm the persistence of losses associated with the Civil War into the postwar period, or the failure of the New Economic Policy to achieve full recovery, or some mixture of both. We conclude that the Great War and Civil War produced the deepest economic trauma of Russia’s troubled twentieth century.

description: We analyze the welfare cost of inflation in a model with cash-in-advance constraints and an endogenous distribution of establishments’ productivities. Inflation distorts aggregate productivity through firm entry dynamics. The model is calibrated to the United States economy and the long-run equilibrium properties are compared at low and high inflation. We find that increasing the annual inflation rate by 10 percentage points above the average rate in the U.S. would result in a fall in average productivity of roughly 1.3 percent. This decrease in productivity is not innocuous: it is responsible for about one half of the welfare cost of inflation.
Self-Calibration of Cluster Dark Energy Studies: Counts in Cells

description: Cluster number counts can constrain the properties of dark energy if and only if the evolution in the relationship between observable quantities and the cluster mass can be calibrated. Next generation surveys with ~10000 clusters will have sufficient statistics to enable some degree of self-calibration. The excess variance of counts due to the clustering of clusters provides such an opportunity and can be measured from the survey without additional observational cost. It can minimize the degradation in dark energy constraints due to an unknown power law evolution in the mass-observable relation improving constraints on the dark energy equation of state by a factor of 2 or more to sigma(w)=0.06 for a deep 4000 deg2 survey.

REDUNDANT AND NON-BINDING CONSTRAINTS IN LINEAR PROGRAMMING PROBLEMS

Research Methods/ Statistical Methods

description: General mathematical programming problems may contain redundant and nonbinding constraints. These are constraints, which can be removed from the problem without altering the feasible region or the optimal solution respectivily. Here we consider some more theoretical definitions and give reasons for selecting a special one. The emphasis is put on linear programming, but most of the material can be applied to any mathematical programming problem with linear constraints. To identify redundant constraints several methods have been proposed. We give a survey and show that all these methods are variants of a general method (Telgen (1977a)). No method is known to identify non-binding constraints directly; therefore we give some indirect ways to identify non-binding constraints. Finally, some remarks are made concerning the importance of the methods to identify redundant and nonbinding constraints in practical linear programming problems, both from a managerial and from a computational point of view.

description: We present HST spectroscopy of the nucleus of M31 obtained with STIS. Spectra taken around the CaT lines at 8500 see only the red giants in the double bright- ness peaks P1 and P2. In contrast, spectra taken at 3600-5100 A are sensitive to the tiny blue nucleus embedded in P2, the lower surface brightness red nucleus. P2 has a K-type spectrum, but the embedded blue nucleus has an A-type spectrum with strong Balmer absorption lines. Given the small likelihood for stellar collisions, a 200 Myr old starburst appears to be the most plausible origin of the blue nucleus. In stellar population, size, and velocity dispersion, the blue nucleus is so different from P1 and P2 that we call it P3. The line-of-sight velocity distributions of the red stars in P1+P2 strengthen the support for Tremaine s eccentric disk model. The kinematics of P3 is consistent with a circular stellar disk in Keplerian rotation around a super-massive black hole with M_bh = 1.4 x 10^8 M_sun. The P3 and the P1+P2 disks rotate in the same sense and are almost coplanar. The observed velocity dispersion of P3 is due to blurred rotation and has a maximum value of sigma = 1183+-201 km/s. The observed peak rotation velocity of P3 is V = 618+-81 km/s at radius 0.05" = 0.19 pc corresponding to a circular rotation velocity at this radius of ~1700 km/s. Any dark star cluster alternative to a black hole must have a half-mass radius <= 0.03" = 0.11 pc. We show that this excludes clusters of brown dwarfs or dead stars on astrophysical grounds.

With the increasing demand for paper in the developing countries such as China and India, the growing concerns for the environmental impacts are expected to accumulate over time. Our report investigates the environmental concerns in the production stages of both types of paper. The investigation focuses on various categories such as chemicals used in bleaching, different types of bleaching processes, quantitative analysis on wastewater, and alternative methods of bleaching process. This report includes a case study in Iran, academic journals, and data collected from past production reports. Based on the findings from the investigation, it is environmentally prominent to opt for bagasse (sugar cane) paper when it is challenged with wood fiber paper due to the quantity of wastes generated, and the amount of water required to effectively treat the said wastes.

description: Abstract Heeding the call of the special issue, we look at the past decade's advances in public opinion studies of our understanding of the relationship between white racial identities, attitudes, and presidential voting preferences. Following a short review of developments in the literature during the Obama years, we critically evaluated four theories explaining whites' support for Trump: racial resentment, xenophobia, sexism, and white identity. Using data from three ANES studies, we test the relative explanatory power of all four approaches in predicting a vote for Trump during the 2016 Republican primary, the 2016 election, and intent to vote for him in 2020. The results suggest that xenophobia had the most consistent effect across all models, followed by racial resentment and sexism. White identity appears to have influenced voting for Trump in the primary and it could also have an impact in the 2020 election, but its effect in the 2016 general election does not appear to have been consistent with theoretical expectations. Finally, we use these results to think critically about the state of the field and propose new questions and challenges for research.

description: In the network design problem we are given a weighted undirected graph. We wish to find a subgraph which connects all the original vertices and minimizes the sum of the shortest path weights between all vertex pairs, subject to a budget constraint on the sum of its edge weights. In this note we establish NP-completeness for the network design problem, even for the simple case where all edge weights are equal and the budget restricts the choice to spanning trees. This result justifies the development of enumerative optimization methods and of approximation algorithms, such as those described in a recent paper by R. Dionne and M. Florian.

description: We present spectral and timing results from a long (130 ks) XMM-NEWTON EPIC observation of the nucleus of the Seyfert/LINER galaxy M 81. During the observation the X-ray flux varied by 20%, but there was no significant change in spectral shape. The 2-10 keV spectrum is well described by a power law continuum and three narrow Fe K emission lines at 6.4, 6.7 and 6.96 keV. The three emission lines have equivalent widths of 39, 47, and 37 eV respectively. The ratios of the three lines are thus more similar to those observed from the Galactic Centre region than to those typically observed from Seyfert galaxies. The high ionization lines most likely originate either from photoionized gas within 0.1 pc of the nucleus of M 81, or from a non-thermal distribution of cosmic-ray electrons interacting with the 0.2-0.6 keV thermal plasma which is found in the bulge of M 81.

description: As shown by Overhauser and others, the pair-distribution function $g(r)$ of a many-electron system may be found by solving a two-electron scattering problem with an effective screened electron-electron repulsion $V(r)$. We propose a simple physical picture in which this screened repulsion is the ``dressed-dressed'' interaction between two neutral objects, each an electron surrounded by its full-coupling exchange-correlation hole. For the effective interaction between two electrons of antiparallel spin in a high-density uniform electron gas of arbitrary spin polarization, we confirm that this picture is qualitatively correct. In contrast, the ``bare-dressed'' interaction is too repulsive, and does not have the expected symmetry $V_{\ud}(r) = V_{\du}(r)$. The simple original Overhauser model interaction, independent of the relative spin polarization $ζ$, does not capture the $ζ$-dependence of the correlation contribution to $g(r=0)$.

description: Branch-and-bound algorithms are widely used to solve combinatorial maximization problems. At each step of such an algorithm a search strategy selects an active subset of feasible solutions for examination. In this paper we discuss the formal properties and the practical value of search strategies based on branching from the largest upper bound (BLUB strategies). We investigate conditions under which BLUB strategies are optimal in the sense that they minimize the number of subsets generated. Counterexamples show that the conditions given in the literature are not strong enough and a correct optimality condition is formulated. Finally, we argue that the practical objections raised against BLUB strategies are not necessarily convincing.

description: In this paper Monte Carlo simulation is used in order to compare the performance of five different methods to estimate quarterly models with partly missing quarterly observations. The methods are compared on the basis of the parameter estimates they produce. The first three methods solve the estimation problem in two steps: first the yearly series is disaggregated into a quarterly one and then the quarterly model is estimated. The fourth method considers disaggregation of the yearly series within the context of the model to be estimated and arrives simultaneously at estimates of the missing quarterly observations and of the parameters of the model. The last method simply consists of maximum likelihood estimation of the yearly model. The conclusions from this simulation study are twofold: (i) none of the methods that are developed for the purpose of estimating quarterly models with partly missing observations performs significantly better than maximum likelihood estimation of the yearly model; (ii) the standard errors that result from application of the first three methods are deceptive.

A multi-wavelength scattered light analysis of the dust grain population in the GG Tau circumbinary ring

description: We present the first 3.8 micron image of the dusty ring surrounding the young binary system GG Tau, obtained with the W. M. Keck II 10m telescope's adaptive optics system. This is the longest wavelength at which the ring has been detected in scattered light so far, allowing a multi-wavelength analysis of the scattering properties of the dust grains present in this protoplanetary disk in combination with previous, shorter wavelengths, HST images. We find that the scattering phase function of the dust grains in the disk is only weakly dependent on the wavelength. This is inconsistent with dust models inferred from observations of the interstellar medium or dense molecular clouds. In particular, the strongly forward-throwing scattering phase function observed at 3.8 micron implies a significant increase in the population of large (>~1 micron) grains, which provides direct evidence for grain growth in the ring. However, the grain size distribution required to match the 3.8 micron image of the ring is incompatible with its published 1 micron polarization map, implying that the dust population is not uniform throughout the ring. We also show that our 3.8 micron scattered light image probes a deeper layer of the ring than previous shorter wavelength images, as demonstrated by a shift in the location of the inner edge of the disk's scattered light distribution between 1 and 3.8 micron. We therefore propose a stratified structure for the ring in which the surface layers, located ~50 AU above the ring midplane, contain dust grains that are very similar to those found in dense molecular clouds, while the region of the ring located ~25 AU from the midplane contains significantly larger grains. This stratified structure is likely the result of vertical dust settling and/or preferred grain growth in the densest parts of the ring.

description: The focus of our group’s project was to create a resource tool for those involved with the planning and coordinating of the upcoming fine dining restaurant ‘The Perch’, to be located in the new SUB at UBC. Building on the AMS Lighter Footprint Strategy, our methods for compiling resources and developing a handbook consisted of many steps, all which tied back to the vision of sustainability. These included the initial phases of reviewing literature and past AMS projects as well as conducting interviews with local restaurants holding a similar sustainable-fine-dining vision to gain insight on their motives and success factors. From this information our group compiled a list of criteria important for sustainable menu success, which included nutritional, organic, local/seasonal, fair trade, animal welfare, vegetarian, and vegan elements. We then conducted a simple survey to determine the importance of each criterion to a convenience sample, enabling us to gain insight as to how the categories ranked among the public and proceed to make recommendations that best matched the criteria demand. Upon analyzing the gathered data, we found a common theme of using and promoting local/seasonal foods from the restaurant interviews, and through the survey established a list of sustainable criteria ranked from most important to least important being; nutrition, local/seasonal, animal welfare, fair trade, organic, vegetarian, vegan. Further, our group was able to provide recommendations on narrowing ‘The Perch’s menu theme to ingredients that incorporate the popular criteria as indicated by restaurant interviewees and survey participants. Through developing this handbook, we hope to have addressed the needs of the project by targeting the vision of ‘The Perch” restaurant and compiling a list of resources that are easily accessible and useful.

description: Credit scoring is without a doubt one of the oldest applications of analytics. In recent years, a multitude of sophisticated classification techniques have been developed to improve the statistical performance of credit scoring models. Instead of focusing on the techniques themselves, this paper leverages alternative data sources to enhance both statistical and economic model performance. The study demonstrates how including call networks, in the context of positive credit information, as a new Big Data source has added value in terms of profit by applying a profit measure and profit-based feature selection. A unique combination of datasets, including call-detail records, credit and debit account information of customers is used to create scorecards for credit card applicants. Call-detail records are used to build call networks and advanced social network analytics techniques are applied to propagate influence from prior defaulters throughout the network to produce influence scores. The results show that combining call-detail records with traditional data in credit scoring models significantly increases their performance when measured in AUC. In terms of profit, the best model is the one built with only calling behavior features. In addition, the calling behavior features are the most predictive in other models, both in terms of statistical and economic performance. The results have an impact in terms of ethical use of call-detail records, regulatory implications, financial inclusion, as well as data sharing and privacy.

description: Carol is the granddaughter of Herbert Arthur Stone. He survived the war and was demobbed 27th May 1919.

He was a member of the ground crew for the Royal Flying Corps. His service number was 58477 reg no AM3. One of the photos brought in was of him on the back row far right, of a group with a name board of 'Tails Up'. It is not known what this was i.e. maybe a football or rugby team or maybe an entertainment group.

Herbert was born in 1898. Before the war he was a carpenter and so thoughts are that he repaired the frameworks etc of the wooden framed aircrafts. On his identity papers it states that he was a Rigger (Aero) in France.

A tin of medals was brought in and although Herbert was reluctant to talk about the war to family and friends it was said in the family that he had helped to pull a pilot from a burning aircraft.

He was demobbed at no 1 dispersal unit at Favant Saisbury on 27th May 1919 and died in November 1973 having lived in Brislington.

description: Recent developments in the theory of computational complexity as applied to combinatorial problems have revealed the existence of a large class of so-called NP-complete problems, either all or none of which are solvable in polynomial time. Since many infamous combinatorial problems have been proved to be NP-complete, the latter alternative seems far more likely. In that sense, NP-completeness of a problem justifies the use of enumerative optimization methods and of approximation algorithms. In this paper we give an informal introduction to the theory of NP-completeness and derive some fundamental results, in the hope of stimulating further use of this valuable analytical tool.

description: Carbon nanotubes and biological filaments each spontaneously assemble into kinked helices, rings, and "tennis racket" shapes due to competition between elastic and interfacial effects. We show that the slender geometry is a more important determinant of the morphology than any molecular details. Our mesoscopic continuum theory is capable of quantifying observations of these structures, and is suggestive of their occurrence in other filamentous assemblies as well.
