Diffraction in the Semiclassical Approximation to Feynman's Path Integral Representation of the Green Function

description: We derive the semiclassical approximation to Feynman's path integral representation of the energy Green function of a massless particle in the shadow region of an ideal obstacle in a medium. The wavelength of the particle is assumed to be comparable to or smaller than any relevant length of the problem. Classical paths with extremal length partially creep along the obstacle and their fluctuations are subject to non-holonomic constraints. If the medium is a vacuum, the asymptotic contribution from a single classical path of overall length L to the energy Green function at energy E is that of a non-relativistic particle of mass E/c^2 moving in the two-dimensional space orthogonal to the classical path for a time τ=L/c. Dirichlet boundary conditions at the surface of the obstacle constrain the motion of the particle to the exterior half-space and result in an effective time-dependent but spatially constant force that is inversely proportional to the radius of curvature of the classical path. We relate the diffractive, classically forbidden motion in the "creeping" case to the classically allowed motion in the "whispering gallery" case by analytic continuation in the curvature of the classical path. The non-holonomic constraint implies that the surface of the obstacle becomes a zero-dimensional caustic of the particle's motion. We solve this problem for extremal rays with piecewise constant curvature and provide uniform asymptotic expressions that are approximately valid in the penumbra as well as in the deep shadow of a sphere.

description: The long-wavelength coherent overdensity and tidal force, which are not direct observables for a finite-volume survey, affect time evolution of cosmic structure formation and therefore clustering observables through the mode coupling. In this paper we develop an "anisotropic" separate universe (SU) simulation technique to simulate large-scale structure formation taking into account the effect of large-scale tidal force into the anisotropic expansion of local background. We modify the TreePM N-body simulation code to implement the anisotropic SU simulations, and then study the "response" function of matter power spectrum that describes how the matter power spectrum responds to the large-scale tidal effect as a function of wavenumber and redshift for a given global cosmology. We test and validate the SU simulation results from the comparison with the perturbation theory predictions and the results from high-resolution PM simulations. We find that the response function displays characteristic scale dependences over the range of scales down to nonlinear scales, up to k ~ 6 h/Mpc.

An investigation into sustainable energy storage systems for buildings

Publisher: name: The University of British Columbia
Year: 2012

description: This report documents the research that has been done on the use of Energy Storage Systems (ESS). To ensure the reliability of the alternative energy source for the new SUB, ESS needs to be incorporated in the energy system to store electricity at off-peak periods and release the energy at peak time. Three storage techniques are presented in the report, including the most traditional batteries, and two promising techniques— the flywheel system, and the superconducting magnetic energy system. Operation and implementation of every energy storage method is covered. In addition, each technique’s advantages and disadvantages are analyzed, and triple-bottom line analyses are made. Although battery is very reliable and has an energy density of about 80kwh/kg, it has a cost of over $1/kwh, and it is non-environmentally friendly; the flywheel is both reliable and efficient; the superconducting magnetic energy system is 97% efficient and reliable, still it is not cost-effective at small scale. Based on the cost, social and environmental impacts, the flywheel energy storage system is recommended for the new SUB.

description: Vacuum expectation values for one Wegner-Wilson loop representing a moving quark-antiquark pair are calculated in four-dimensional Euclidean and Minkowski space-time. The calculation uses gluon field strength correlators with perturbative gluon exchange and non-perturbative correlations from the stochastic vacuum model. The expectation value of a Wegner-Wilson loop forming a hyperbolic angle in Minkowski space-time is connected by an analytical continuation to the expectation value of the Wegner-Wilson loop in Euclidean four-space. The obtained result shows how confinement enters into the light-cone Hamiltonian for valence quarks independently of the chosen model.

description: Can local fluctuations of a ``Quintessence'' scalar field play a dynamical role in the gravitational clustering and cosmic structure formation process? We address this question in the general framework of scalar-tensor theories of gravity. Non-linear energy density perturbations, both in the scalar field and matter component, and linear metric perturbations are accounted for in the perturbed Einstein's equations. We derive the Newtonian limit of the relevant equations for clustering in scalar-tensor cosmologies. We then specialize to non-linear perturbations of the ``Extended Quintessence'' model of Dark Energy; in such a model, a non-minimally coupled scalar field is thought to be responsible for driving the present accelerated phase of the Universe expansion. The interplay between Dark Energy and Dark Matter is displayed in the equations governing the growth of structure in the Universe.

description: Female primates carry and nurse the fetus, and thus have the …rst responsibility for rearing the o¤spring. Assuming males are at least equally adept at obtaining food, males might either share surplus food with females or consume the food themselves. The distribution of this surplus is the subject of a battle of the sexes. If females succeed in obtaining a large share of the surplus, then there is little size dimorphism between males and females; otherwise males might use the surplus themselves to become larger and stronger, and to engage in sexual competition with other males. Besides competing with males, females may compete with each other. Dependency may coincide with sexual competitiveness (sexiness). This paper introduces these ideas in a game theoretic setting and derives a simple bound, called the ‘®-male condition, on the male ‘sexiness’ required for a nonsupportive strategy to be worthwhile.

The Political Economy of a Soviet Military R&D Failure: Steam Power for Aviation, 1932 to 1939

description: By studying a Soviet R&D failure, the prewar attempt to create a new aeroengine technology based on the steam turbine, we find out more about the motivations, strategies, and payoffs of principals and agents in the Soviet command economy. Alternative approaches to the evaluation of R&D failure are outlined. New archival documentation shows the scale and scope of the Soviet R&D effort in this field. The allocation of R&D resources resulted from agents’ horizontal interactions within a vertical command hierarchy. Project funding was determined in a context of biased information, adverse selection, and agents’ rent seeking. Funding was rationed across projects and through time. Budget constraints on individual projects were softened in the presence of sunk costs, but were hardened periodically. There is no evidence that rents were intentionally distributed through the Soviet military R&D system to win trust or reward loyalty; the termination of aviation steam power R&D in 1939 despite the sunk costs they represented was timely.

description: This thesis examines contemporary architectural culture through the lens of queering - a theoretical framework that challenges normative spatial practicesand social structures. It critically analyses how modern architecture has shifted from human-centred design to profit-driven development, and explores whether queering methodologies can offer transformative solutions to the challenges facing architecture, society and the environment. The research explores how rapid technological development has mechanised architectural practice, potentially diminishing its creative and humanistic elements. Through experimental writing that takes the form of a personal diary, this thesis traces architectural discourse from early modernism, beginning with a critical examination of Adolf Loos’s anti-ornamental stance and its unintended consequences in contemporary practice.The analysis extends through various queer theoretical frameworks, examining how concepts of masking,performance and authenticity manifest in architectural space.The work culminates in a deeply personal examination of contemporary architectural practice, exploring how current working conditions and institutional structures affect designers, architects and students.Drawing on diverse methodological approaches including historical analysis, queer theory and autoethnography,the thesis examines how queering can functionas both critique and creative practice in architecture.It analyzes specific case studies, including the Villa Müller, architectural spaces in Seville and Athens, and the opening ceremony of the Paris 2024 Olympic Games, to demonstrate how queering can be manifested in both built form and cultural events. Ultimately, the research proposes that queering offers potential strategies for liberating architecture from current constraints and suggests pathways towards more inclusive, expressive and humane spatial practices.

TYPE LOCALITY. — Le Quesnoy, Chevrière, region of Creil, Oise department, France.
GEOLOGICAL AGE. — Lowermost Eocene, Sparnacian, level MP 7 of the mammal fauna of Dormaal.
STATE OF PRESERVATION. — This specimen is incomplete, the head and main part of thorax are missing. Three tarsal segments of a leg and five apical segments of an antenna are visible.
DESCRIPTION
Length of the abdomen 4.8 mm, width 2.3 mm; seven abdominal segment visible, thus it is probably a female; two very short extensions, 0.6 mm long, on the last abdominal segment, overlapping cerci; cerci long and narrow, 2.5 mm long, about 0.5 mm wide, crossing apically, curved upwards at the apex; only distal parts of tegmina preserved, with a darker strip along inner margin and posterior margin straight; hindwings present; antenna bicoloured: the two apical segments are dark; the two following ones are clear coloured, others are dark; tarsal segments pubescent, especially the first and the second; second tarsal segment not bilobate, weakly prolonged below the third, both being clearly separated; third tarsal segment short, in a form of enlarged club; no arolium.
DISCUSSION
 The preserved parts of this fossil are very similar to those of the extant Dermaptera. It is most probably a female, thus difficult to attribute to a precise family, even if it was more complete. It clearly corresponds to a genus and species different from Chelisoficula caussaneli n. gen., n. sp. (cerci very different, second tarsal segment less prolonged below the third). It is probably not a chelisochid-forficulid type. It could correspond to a labiid-type but with no accuracy.

We compare the result of $\mathrm{Re}A_2$ with previous results calculated by several methods, and experiment. We also show the I=2 $ππ$ scattering phase shift.

description: The non-linear evolution of dense partonic systems has been suggested as one of the novel physics mechanisms relevant to the dynamics of hadron-nucleus and nucleus-nucleus collisions at collider energies. Here we study to what extent the description of Cronin enhancement in the framework of this non-linear evolution is consistent with the recent observation in 200 AGeV d--Au collisions at the Relativistic Heavy Ion Collider. We solve the Balitsky-Kovchegov evolution equation numerically for several initial conditions encoding Cronin enhancement. We find that the properly normalized nuclear gluon distribution is suppressed at all momenta relative to that of a single nucleon. Calculating the resulting spectrum of produced gluons in p-A and A-A collisions, we establish that the nonlinear QCD evolution is unable to generate a Cronin type enhancement, and that it quickly erases any such enhancement which may be present at lower energies.

description: This paper studies a strategic aspect of prot-sharing in an oligopolistic industry with a monopoly union. Whenever a uniform prot share exists in the industry, we show that a union that values the per worker remuneration positively, may have incentives to reduce industry employment, decreasing thus total output and causing total prots to increase. Thus, we show that prot-sharing may lead to higher prots for such an industry even if productivity eects are absent.

description: Currency substitution appears to be an important issue affecting the design of monetary policy, especially in transition economies. Therefore, this paper strives to analyze the particular relevance of a currency substitution phenomenon for the Czech Republic is case. We initially discuss various approaches and definitions of currency substitution that found in the literature. Subsequently, we discuss the role of currency substitution in small open economies in transition with some illustrations relating to the Czech Republic - we distinguish and analyse a locally and globally substituting currency from a substituted one and consequences of euroization. The empirical part of this paper presents estimations of modified Branson and Henderson portfolio model for the Czech Republic’s case. This provides a multi-perspective approach to currency substitution in a broad sense. Further, we attempt to intensify the robustness of our estimation, applying several cointegration techniques. These are namely the Johansen procedure, the ARDL, the DOLS and the ADL. Finally, we discuss potential implications of currency and assets substitution according to our estimates present in the Czech economy.

description: In a robotic soccer team, goalkeeper is an important challenging role, which has different characteristics from the other teammates. This paper proposes a new learning-based behavior model for a soccer goalkeeper robot by using Petri nets. The model focuses on modeling and analyzing, both qualitatively and quantitatively, for the goalkeeper role so that we have a model-based knowledge of the task performance in different possible situations. The different primitive actions and behaviors as well as the events to switch between them, and also environment models were designed and implemented. For this purpose, a modeling and analysis framework based on Petri nets is used, which enables modeling a robot task, analyzing its qualitative and quantitative properties and using the Petri net representation for actual plan execution. The proposed model building blocks and some tasks of robot are detailed. The novelty of approach is considering some alternatives through tasks execution, which are implemented by conflicts in their Petri net models, and also Q_learning employment in these decision points in order to learn the best policy. Therefore, the execution of actions in different tasks will be controlled effectively. The results of theoretical analysis of some case studies show impressive performance improvement in goalkeeper task execution.

As liquid-crystalline mesogens achiral, nematogen and chiral cholesteric guest molecules infiltrated into nanochannels by spontaneous imbibition were chosen. The molecular ordering inside the nanochannels, which can be tailored by modifying the surface anchoring, was characterized by optical polarimetry (linear and/or circular birefringence) in combination with X-ray diffraction. For the synthesis of the solid crystalline nanocomposites ferroelectric triglycine sulfate (TGS) nanocrystals were deposited into the nanochannels by slow evaporation of saturated water solutions imbibed into the porous hosts. Their textural and physicochemical properties were explored by x-ray diffraction, scanning electron microscopy and dielectric techniques.

description: In this paper we strive to present a somewhat internationalised view of demand for money as applied to the Czech Republic. We extend the traditional money demand function, consisting purely of domestic variables, to include certain foreign determinants that probably affect the demand for money in a small open transition economy. We do so in the case of both narrow and broad money. For the purposes of generalisation and robust estimates we employ several estimation techniques, namely the Johansen procedure, ARDL, DOLS and ADL. We also consider the aspect of the stability of such estimates. Finally, we analyse the possible effects on prices and output of disequilibria on money market. We have found that a liquidity gap probably has a significant influence on both prices and output.

description: The following report describes the current assessment of plastic garbage collecting system at the University of British Columbia. First, it explains the general concepts of the degradable plastic bag and its characteristics with respect to the sustainability. Then, it goes on to the regular plastic bag and finally, the plastic bag-free section. Those three different types of the garbage colleting systems illustrate the environmental, the social, and the economic impacts. By comparing and contrasting those different types of garbage collecting system at UBC, the reasonable recommendation and solutions can be made as to what would be a good alternative to the current plastic bag being used. The scope of the report is mostly concentrated on the usage of the plastic bags for the garbage bins and the waste containers. Some cost approximations were made in order to approach the alternative solutions.

Most of them modify the gauge transformations of the free theory but the commutator algebra of the deformed gauge transformations remains Abelian in all cases. All of these interactions contain terms cubic in the Curtright fields with four or five derivatives, which are reminiscent of Yang-Mills, Chapline-Manton, Freedman-Townsend and Chern-Simons interactions, respectively.

description: Elimination of redundancies in the memory representation is necessary for fast and efficient analysis of large sets of fuzzy data. In this work, we use MTBDDs as the underlying data-structure to represent fuzzy sets and binary fuzzy relations. This leads to elimination of redundancies in the representation, less computations, and faster analyses. We also extended a BDD package (BuDDy) to support MTBDDs in general and fuzzy sets and relations in particular. Representation and manipulation of MTBDD based fuzzy sets and binary fuzzy relations are described in this paper. These include design and implementation of different fuzzy operations such as max, min and max-min composition. In particular, an efficient algorithm for computing max-min composition is presented. Effectiveness of our MTBDD based implementation is shown by applying it on fuzzy connectedness and image segmentation problem. Compared to a base implementation, the running time of the MTBDD based implementation was faster (in our test cases) by a factor ranging from 2 to 27. Also, when the MTBDD based data-structure was employed, the memory needed to represent the final results was improved by a factor ranging from 37.9 to 265.5. We also describe our base implementation which is based on matrices

description: This paper shows that macroeconomic movements have strong effects on the happiness of nations. First, we find that there are clear microeconomic patterns in the psychological well-being levels of a quarter of a million randomly sampled Europeans and Americans from the 1970's to the 1990's. Happiness equations are monotonically increasing in income, and have a similar structure in different countries. Second, movements in reported well-being are correlated with changes in macroeconomic variables such as Gross Domestic Product. This holds true after controlling for the personal characteristics of respondents, country fixed-effects, year dummies, and country-specific time trends. Third, the paper establishes that recessions create psychic losses that extend beyond the fall in GDP and rise in the number of people unemployed. These losses are large. Fourth, the welfare state appears to be a compensating force: higher unemployment benefits are associated with higher national well-being.

description: We have measured the transverse field muon spin precession in the flux lattice (FL) state of the two gap superconductor MgB2 and of the electron doped compounds Mg1-xAlxB2 in magnetic fields up to 2.8T. We show the effect of the two gaps on the internal field distribution in the FL, from which we determine two coherence length parameters and the doping dependence of the London penetration depth. This is an independent determination of the complex vortex structure already suggested by the STM observation of large vortices in a MgB2 single crystal. Our data agrees quantitatively with STM and we thus validate a new phenomenological model for the internal fields.

description: We present an update of the MILC studies of the physics of light pseudoscalars using improved staggered fermions. New runs at lighter quark mass, as well as increased statistics for older sets, are enabling us to improve the results for decay constants in full QCD. In addition, we have analyzed quenched runs at two different lattice spacings. This makes possible a test of the applicability of staggered chiral perturbation theory in a different context.

description: One of the most important steps which is used in every data mining projects is searching an object or some similar objects in a data set. For geometric data, there are some methods that measure the diference between two objects. In recent years, researchers have focused on these types of metrics and used them in diferent applications (e.g., shape matching, machine vision, map generation, etc.). The query problem in these kinds of applications is more complicated when we have big data. In this paper, a new metric is presented which works efciently when the geometric objects are in discrete form (e.g., polygon or chain). The presented method is important from a theoretical point of view, and its diferences with other similar metrics are discussed in this paper

Dermaptera

description: Dermaptera family indet. 2 (Fig. 6B)  MATERIAL EXAMINED. — Specimen PA 2987, in the same piece of amber with organic remains; in collection De Ploëg and Indivision Langlois-Meurine, deposited in Muséum national d’Histoire naturelle, Paris.
TYPE LOCALITY. — Le Quesnoy, Chevrière, region of Creil, Oise department, France.
GEOLOGICAL AGE. — Lowermost Eocene, Sparnacian, level MP 7 of the mammal fauna of Dormaal.
DESCRIPTION
Only the two cerci with the five last abdominal segments are preserved; cerci narrow and relatively long, 3.8 mm long for a total length of 2.0 mm for the five distal abdominal segments; cerci straight, with the apices crossing; small teeth on the inner sides of cerci and few sparse setae.
DISCUSSION
It is not possible to determine whether this fossil is a larva or an adult. Nevertheless, this type of long and narrow cerci occurs in modern dermapteran families Labiidae or Forficulidae. The main interest of this fossil is to show that there is a third species of Dermaptera in the amber of this outcrop.

description: This paper estimates micro-econometric happiness equations for the United States and Great Britain. Reported levels of wellbeing have declined over the last quarter of a century in the US; life satisfaction has run approximately flat through time in Britain. These findings are consistent with the Easterlin hypothesis (1974, 1995). The happiness of American blacks, however, has risen. Despite legislation on gender discrimination, the well-being of women has declined. White women in the US have been the biggest losers. Well-being equations have a stable structure. Money buys happiness. People care also about relative income. Wellbeing is U-shaped in age. The paper estimates the dollar values of events like unemployment and divorce. They are large. A lasting marriage (compared to widow-hood as a ‘natural’ experiment), for example, is estimated to be worth $100,000 a year.

description: This paper studies workers’ lives in modern Britain. It uses longitudinal data to examine stress and job satisfaction through the decade of the 1990s. The results are disturbing. On both measures, the wellbeing of British public sector workers worsened sharply over the decade. The size of the deterioration was between one half point and one full point on a standard GHQ mental stress scale. This is remarkably large. Stress levels among private sector employees also rose. Job satisfaction in the private sector ran approximately flat through time. These findings may be of interest to nations who are thinking of adopting the British government’s policies towards the public sector, and to those who have conjectured that working life is becoming more pressurised.
Loop Variables with Chan-Paton Factors

description: The Loop Variable method that has been developed for the U(1) bosonic open string is generalized to include non-Abelian gauge invariance by incorporating "Chan-Paton" gauge group indices. The scale transformation symmetry $k(s) \to k(s) λ(s)$ that was responsible for gauge invariance in the U(1) case continues to be a symmetry. In addition there is a "rotation" symmetry. Both symmetries crucially involve the massive modes. However it is plausible that only a linear combination, which is the usual Yang-Mills transformation on massless fields, has a smooth (world sheet) continuum limit. We also illustrate how an infinite number of terms in the equation of motion in the cutoff theory add up to give a term that has a smooth continuum limit, and thus contributes to the low energy Yang-Mills equation of motion.

description: Mid-term quasi-periodicities in solar coronal mass ejections (CMEs) during the most recent solar maximum cycle 23 are reported here for the first time using the four-year data (February 5, 1999 to February 10, 2003) of the Large Angle Spectrometric Coronagraph (LASCO) onboard the Solar and Heliospheric Observatory (SOHO). In parallel, mid-term quasi-periodicities in solar X-ray flares (class >M5.0) from the Geosynchronous Operational Environment Satellites (GOES) and in daily averages of Ap index for geomagnetic disturbances from the World Data Center (WDC) at the International Association for Geomagnetism and Aeronomy (IAGA) are also examined for the same four-year time span. Several conceptual aspects of possible equatorially trapped Rossby-type waves at and beneath the solar photosphere are discussed.

description: One of the most important questions for managers of corporations is how they select a smart strategy for their corporations. To answer this question, Managers should consider some dimensions witch impact on the future of the corporation, and then they select a suitable strategy for their corporations. This paper presents a novel model (FASE model) for evaluating strategic position and choosing smart strategy based on Big Data techniques and SPACE matrix. In order to achieve the best position in the market, FASE model facilitates selecting the best strategy among: aggressive, conservative, defensive, and competitive strategies. FASE model consists of three main processes namely Fuzzy-Cmeans, Apriori association rule inducer, SPACE matrix. Fuzzy-Cmeans algorithm is used for clustering customers based on RFM values and behavioral scoring. The results of the clustering were then profiled on customers’ attributes using Apriori association rule inducer. A SPACE matrix was used to evaluate the strategic position and to choose smart strategy. To get a better understanding of the FASE model, the banking case has been selected and FASE model is applied over that.
