description: We reconsider Chern-Simons gauge theory on a Seifert manifold M, which is the total space of a nontrivial circle bundle over a Riemann surface, possibly with orbifold points. As shown in previous work with Witten, the path integral technique of non-abelian localization can be used to express the partition function of Chern-Simons theory in terms of the equivariant cohomology of the moduli space of flat connections on M. Here we extend this result to apply to the expectation values of Wilson loop operators which wrap the circle fibers of M. Under localization, such a Wilson loop operator reduces naturally to the Chern character of an associated universal bundle over the moduli space. Along the way, we demonstrate that the stationary-phase approximation to the Wilson loop path integral is exact for torus knots, an observation made empirically by Lawrence and Rozansky prior to this work.

description: We describe a model of inelastic and elastic collisional dynamics of atoms in an optical dipole trap that utilizes numerical evaluation of statistical mechanical quantities and numerical solution of equations for the evolution of number and temperature of trapped atoms. It can be used for traps that possess little spatial symmetry and when the ratio of trap depth to sample temperature is relatively small. We compare simulation results with experiments on $^{88}$Sr and $^{84}$Sr, which have well-characterized collisional properties.

description: Over the past century, the ownership of film and television companies has transferred from small-scale, private independent operations to large, often publicly held multimedia conglomerates. What does the ownership landscape for media corporations look like now? How does the current ownership lanscape, in which telecomminications and technology companies are more actively involved, impact labor relations and the development of streaming services? This paper seeks to answer the questions above. The first question addresses the historical factors that drove the industry into its consolidated state; it also pertains to the ownership structures of individual media conglomerates, which currently operate across different media sectors. The second question addresses two direct implications of recent ownership chages: heightened labor tensions between the Hollywood writers and their talent agencies, and the traditional media companies' efforts to join the streaming space to compete with technology companies such as Netflix and Amazon.

description: It has been suggested that the high symmetries in the Schrödinger equation with the Coulomb or harmonic oscillator potentials may remain in the corresponding relativistic Dirac equation. If the principle is correct, in the Dirac equation the potential should have a form as ${(1+β)\over 2}V(r)$ where $V(r)$ is ${-e^2\over r}$ for hydrogen atom and $κr^2$ for harmonic oscillator. However, in the case of hydrogen atom, by this combination the spin-orbit coupling term would not exist and it is inconsistent with the observational spectra of hydrogen atom, so that the symmetry of SO(4) must reduce into SU(2). The governing mechanisms QED and QCD which induce potential are vector-like theories, so at the leading order only vector potential exists. However, the higher order effects may cause a scalar fraction. In this work, we show that for QED, the symmetry restoration is very small and some discussions on the symmetry breaking are made. At the end, we briefly discuss the QCD case and indicate that the situation for QCD is much more complicated and interesting.

description: This thesis explores the effects that COVID-19 has on Italian food traditions. Before the outbreak of the deadly virus, Italian cuisine was becoming a shadow of what it used to be. The increase in tourism and popularity of travel websites made it almost impossible for local businesses and small restaurants to stay open. As a result, regional cooking and traditional healthy food habits were no longer the pillars of Italian cuisine. The needs of the tourists began to outweigh the needs of the locals and authentic Italian cuisine was increasingly harder to encounter. The economic prosperity generated by the hospitality industry overshadowed what attracts tourists to the country in the first place. However, COVID-19 changed the fate of the Italian food landscape. The nation-wide quarantine created an opportunity for re-entry into some of those food traditions that were quickly being lost. Even among the mess, there is a silver lining. Throughout the course of my research, I had to start over twice due to some major road- blocks. In the short time I had to write my thesis, it was hard to build a defense. I advise further research in the topic of discussion.

description: 57Fe Mossbauer spectroscopy measurements are presented in the underdoped Ba(Fe{1-x}Cox)2As2 series for x=0.014 (T_c < 1.4K) and x=0.03 and 0.045 (T_c ~ 2 and 12K respectively). The spectral shapes in the so-called spin-density wave (SDW) phase are interpreted in terms of incommensurate modulation of the magnetic structure, and allow the shape of the modulation to be determined. In undoped BaFe2As2, the magnetic structure is commensurate, and we find that incommensurability is present at the lowest doping level (x=0.014). As Co doping increases, the low temperature modulation progressively loses its "squaredness" and tends to a sine-wave. The same trend occurs for a given doping level, as temperature increases. We find that a magnetic hyperfine component persists far above the SDW transition, its intensity being progressively tranferred to a paramagnetic component on heating.

Bangladeshi Medicinal Plants: Ethnopharmacology, Phytochemistry and Anti-Staphylococcal Activity
Creators: name: Siddique, Holly

description: Antibacterial resistance is a major concern. Due to its new resistance mechanism, it is spreading and emerging globally and thereby threatening the treatment of common infectious diseases. There is no doubt to develop new antibiotic from natural sources to tackle antimicrobial resistance. This study involves, (1) ethnopharmacological survey in Bangladesh and (2) bioassay directed phytochemical investigation to explore antibacterial compounds against MRSA. In 2016, an ethnopharmacological survey conducted in Bangladesh led to the recommendation of 71 medicinal plants by 71 Ayurvedic/Unani practitioners, 21 Ayurvedic patients and 35 local inhabitants for the treatment of infectious diseases. Based on the review of literature, data analysis and ease of availability of the plants, 18 plants were initially selected and collected from Bangladesh. After initial antibacterial screening of 18 plants, five plants (MIC 32-512 μg/ml) were chosen based on potential antibacterial activity. These are (Zingiber montanum, Uraria picta, Diospyros malabarica, Cynometra namiflora, Swertia chirayita). Extensive phytochemical work using different chromatographic (VLC, Coloumn chromatography, SPE, TLC, PTLC) and spectroscopic (NMR, Mass spectromentry, IR) techniques on five Bangladeshi medicinal plants led to the isolation and identification of 25 compounds. Eight terpenes (zerumbol, zerumbone, buddledone A, germacrone, furanodienone, (-) borneol, camphor and 8(17), 12-labdadiene-15, 16-dial) were isolated from Zingiber montanum with the MIC (32- >128 μg/ml). Eugenol and steriods were isolated from Uraria picta (MIC 64- >128 μg/ml). Lupane type triterpenoids (Lupeol, botulin, betulinaldehyde, betulone and messagenin) were isolated and identified from Diospyros malabarica with the MIC (64- >128 μg/ml) while pentacyclic triterpene (glutinol, glutinone), simple phenolic (ethyl 4-ethoxybenzoate) and steroids were isolated from Cynometra ramiflora with MIC (64- >128 μg/ml). A series of xanthones (swerchirin, swertiaperenin, belidifolin and decussatin) were identified from Swertia chirayita with MIC (>128 μg/ml). Among these compounds, 4-ethoxybenzoate, messagenin were identified as new natural compounds. In terms of activity, 8(17), 12-labdadiene-15, 16-dial (32 μg/ml against ATCC 5941) and zerumbol (32 μg/ml against EMRSA 15) showed potential antibacterial activity.

description: We present a model where neutrino masses are generated by a combination of spontaneous R-parity violation and Type III seesaw. In addition to the usual MSSM particle content, our model consists of one extra triplet matter chiral superfield containing heavy SU(2) triplet fermions and its superpartners. R-parity is broken spontaneously when the sneutrinos associated with the one heavy neutrino as well as the three light neutrinos get vacuum expectation values, giving rise to the mixed $8\times 8$ neutralino-neutrino mass matrix. We show that our model can comfortably explain all the existing neutrino oscillation data. Due to the presence of the triplet fermion, we have a pair of additional heavy charged leptons which mix with the standard model charged leptons and the charginos. This gives rise to a $6\times 6$ chargino-charged lepton mass matrix, with 6 massive eigenstates. Finally we discuss about the different R-parity violating possible decay modes and the distinctive collider signatures which our model offers.

description: In Stokes flows, symmetry considerations dictate that a neutrally-buoyant spherical particle will not migrate laterally with respect to the local flow direction. We show that a loss of symmetry due to flow-induced surfactant redistribution leads to cross-stream drift of a spherical drop in Poiseuille flow. We derive analytical expressions for the migration velocity in the limit of small non-uniformities in the surfactant distribution, corresponding to weak-flow conditions or a high-viscosity drop. The analysis predicts that the direction of migration is always towards the flow centerline.

description: We explore the connection between quantum brachistochrone (time-optimal) evolution of a three-qubit system and its residual entanglement called three-tangle. The result shows that the entanglement between two qubits is not required for some brachistochrone evolutions of a three-qubit system. However, the evolution between two distinct states cannot be implemented without its three-tangle, except for the trivial cases in which less than three qubits attend evolution. Although both the probability density function of the time-averaged three-tangle and that of the time-averaged squared concurrence between two subsystems become more and more uniform with the decrease in angles of separation between an initial state and a final state, the features of their most probable values exhibit a different trend.

Financial Crisis

description: The 2008 financial crisis was one of global proportions. Its roots were in the United States’ financial services industry and eventually spread to countries in the Eurozone. In addition to the material effects it had on families and workers in America, it also caused some to question the integrity and stability of the philosophy that its economy was built upon. The people who were responsible for answering this question, in addition to many others, were government figures such as Timothy Geithner, Ben Bernanke, and Henry Paulson. They had the task of explaining to America why they took the actions they did to address the crisis. This project will analyze whether or not Geithner, Bernanke, and Paulson engaged in apologia, also known as defense rhetoric, in their framing of the crisis.

description: We present here a quantum tripwire, which is a quantum optical interrogation technique capable of detecting an intrusion with very low probability of the tripwire being revealed to the intruder. Our scheme combines interaction-free measurement with the quantum Zeno effect in order to interrogate the presence of the intruder without interaction. The tripwire exploits a curious nonlinear behaviour of the quantum Zeno effect we discovered, which occurs in a lossy system. We also employ a statistical hypothesis testing protocol, allowing us to calculate a confidence level of interaction-free measurement after a given number of trials. As a result, our quantum intruder alert system is robust against photon loss and dephasing under realistic atmospheric conditions and its design minimizes the probabilities of false positives and false negatives as well as the probability of becoming visible to the intruder.

description: We systematically study the relationship between equilibrium and non-equilibrium phase diagrams of a system of short-ranged attractive colloids. Using Monte Carlo and Brownian dynamics simulations we find a window of enhanced crystallization that is limited at high interaction strength by a slowing down of the dynamics and at low interaction strength by the high nucleation barrier. We find that the crystallization is enhanced by the metastable gas-liquid binodal by means of a two-stage crystallization process. First, the formation of a dense liquid is observed and second the crystal nucleates within the dense fluid. In addition, we find at low colloid packing fractions a fluid of clusters, and at higher colloid packing fractions a percolating network due to an arrested gas-liquid phase separation that we identify with gelation. We find that this arrest is due to crystallization at low interaction energy and it is caused by a slowing down of the dynamics at high interaction strength. Likewise, we observe that the clusters which are formed at low colloid packing fractions are crystalline at low interaction energy, but glassy at high interaction energy. The clusters coalesce upon encounter.

French oil investments in Canada
Creators: name: Lesage, Jean- Pierre
Publisher: name: University of British Columbia

description: Three French oil companies invested in Canada, they are: — Compagnie Française des Pétroles (C.F.P.), in 1953, which created the French Petroleum Co. of Canada. — Société Nationale des Pétroles d'Aquitaine (S.N.P.A.), in 1963, which created Aquitalne Co. of Canada Ltd. — Entreprise de Recherches et d'activité Petroliéres (E.R.A.P.), in 1963, which created Elf Exploration and Production of Canada Ltd. All these companies are located in Calgary,Alberta. These companies came to Canada for two main reasons: — the stability of the country, both economic and political. — the potential for oil discovery. Their investments are different: — S.N.P.A. invested $58,183,412 (Dec. 31, 1967) or 14% of its total assets. — C.F.P. invested $33,834,213 or 4% of its total assets. — E.R.A.P. invested $9,168,412 or 1.2% of its total assets. Their policies also are different: — S.N.P.A. and C.F.P. work principally in Alberta which can be considered as the most proven zone of Canada. — E.R.A.P. is more interested in the long term and invests much in the Arctic regions of Canada. This leads to differences in their results: — S.N.P.A. is the most successful Of the French Oil Investors: Aquitaine had a production of 5,111,409 barrels in 1967, this represents 33% of the total production of S.N.P.A. for the same year. This is due to the big discovery of Rainbow, Alberta. Its rate of return on investment is 6.0%, which is above the Canadian average of — C.F.P. did not make any big discovery but did make small ones. The production of its subsidiary in Canada was l,ll4,339 barrels in 1967, or .3% of its total production. Its rate of return on investment is 1.9%. — E.R.A.P. is exploring and not producing in Canada. Therefore it appears that except for Aquitaine these investments are not financially profitable for the French companies to date. The total of the French oil companies in Canada represents only 1.4% of the total oil production of Canada. Therefore these investments are not quantitatively significant for Canada. Their significance for Canada is that they are a change from American capital because the United States owned 62% of the Canadian oil industry in 1962. The interest of Canada and France is mutual: the French oil companies wanted to diversify their investments, Canada wanted to diversify its sources of capital .

description: Relativistic self-focusing and channeling of intense laser pulses have been studied in underdense plasma using 2D PIC simulations, for different laser powers and plasma densities. Analytical solutions for the stationary evacuated channels have been recovered in PIC simulations. It is shown that otherwise stable channels can accelerate electrons due to surface waves on the walls of the channels. Relativistic filaments with finite electron density are unstable to transverse modulations which lead in the nonlinear stage to the break-up of laser pulses into independent filaments. Different regimes of relativistic self-focusing and channeling, including electron heating, transverse instability and break-up of the filaments have been discussed and characterized using plasma density and laser power.

description: In this paper we prove a formula, much in the spirit of one due to Rubin, which expresses the leading coefficients of various p-adic L-functions in the presence of an exceptional zero in terms of Nekovar's p-adic height pairings on his extended Selmer groups. In a particular case, the Rubin-style formula we prove recovers a p-adic Kronecker limit formula. In a disjoint case, we observe that our computations with Nekovar's heights agree with the Ferrero- Greenberg formula (more generally, Gross' conjectural formula) for the leading coefficient of the Kubota-Leopoldt p-adic L-function (resp., the Deligne-Ribet p-adic L-function) at s = 0.

La decisión por la “autoidentificación” fue elegida por la falta de definición del campo de las HD, que hace difícil tanto dirigir el cuestionario a una comunidad pre-definida como crear variables discretas. También esto guió la intención detrás del hecho de que que 24 de las 29 fueron preguntas abiertas.

description: We develop an effective description of noise-induced oscillations based on deterministic phase dynamics. The phase equation is constructed to exhibit correct frequency and distribution density of noise-induced oscillations. In the simplest one-dimensional case the effective phase equation is obtained analytically, whereas for more complex situations a simple method of data processing is suggested. As an application an effective coupling function is constructed that quantitatively describes periodically forced noise-induced oscillations.

description: The transport and fluctuation properties of organic molecules ordered parallel between two Au contact leads are investigated by the method of surface Green function. From first-principles simulation the relevant hopping parameters are extracted and used to calculate nonlinear transport coefficients with respect to an external bias voltage. A staggering of conductance is found in dependence on the number of molecules squeezed in between the contacts. The thermal properties show an anomalous behavior whenever the voltage reaches the values of the molecular energy levels active for transport. The thermoelectric figure of merit shows a resonance allowing to reach values even larger than one.

description: We present self-consistent high-resolution simulations of NGC4038/4039 (the "Antennae galaxies") including star formation, supernova feedback and magnetic fields performed with the N-body/SPH code Gadget, in which magnetohydrodynamics are followed with the SPH method. We vary the initial magnetic field in the progenitor disks from 1 nG to 100 muG. At the time of the best match with the central region of the Antennae system the magnetic field has been amplified by compression and shear flows to an equilibrium field of approximately 10 muG, independent of the initial seed field. These simulations are a proof of the principle that galaxy mergers are efficient drivers for the cosmic evolution of magnetic fields. We present a detailed analysis of the magnetic field structure in the central overlap region. Simulated radio and polarization maps are in good morphological and quantitative agreement with the observations. In particular, the two cores with the highest synchrotron intensity and ridges of regular magnetic fields between the cores and at the root of the southern tidal arm develop naturally in our simulations. This indicates that the simulations are capable of realistically following the evolution of the magnetic fields in a highly non-linear environment. We also discuss the relevance of the amplification effect for present day magnetic fields in the context of hierarchical structure formation.

description: Micro- and nanoplastics (MNPs) are increasingly detected in environmental and biological systems, raising concerns about their potential long-term impacts on human health and ecosystems. Despite growing awareness, significant knowledge gaps and uncertainties remain regarding their persistence, bioaccumulation, and detrimental interactions within biological systems. However, as our experience with other classes of synthetic substances, such as CFCs and their ozone-depleting effects, has shown, originally harmless substances can exhibit dangerous properties with dramatic consequences in certain environments. To avoid such unpleasant surprises, prospective risk assessment approaches are necessary to enable a risk-minimizing and sustainable design of new materials and thereby support the Safe and Sustainable by Design Strategy (SSbD) and Circular Economy Action Plan of the EU (2020; 2022).

One of the aims of the PlasticsFatE (Plastics Fate and Effects in the Human Body) Project, supported by Horizon 2020, was to develop a risk assessment and management strategy for plastics based on a Decision Support System (DSS). Developing this tool has shown which knowledge gaps still exist and limit the use of current risk assessment approaches for plastics. This policy brief summarizes the difficulties we still face in the development and application of risk assessment tools and formulates research tasks to enable robust and sustainable risk assessment and risk management for plastics in the future.

description: The addition of Wide Field Camera 3 (WFC3) on the Hubble Space Telescope (HST) has led to a dramatic increase in our ability to study the z>6 Universe. The increase in the near-infrared (NIR) sensitivity of WFC3 over previous instruments has enabled us to reach apparent magnitudes approaching 29 (AB). This allows us to probe the rest-frame ultraviolet (UV) continuum, redshifted into the NIR at $z>6$. Taking advantage of the large optical depths at this redshift, resulting in the Lyman-alpha break, we use a combination of WFC3 imaging and pre-existing Advanced Camera for Surveys (ACS) imaging to search for z approx 7 over 4 fields. Our analysis reveals 29 new z approx 7 star forming galaxy candidates in addition to 16 pre-existing candidates already discovered in these fields. The improved statistics from our doubling of the robust sample of z-drop candidates confirms the previously observed evolution of the bright end of the luminosity function.

Japanese business organization through mentality perspective
Creators: name: Yamashita, Hideo
Publisher: name: University of British Columbia
Year: 2011

description: This paper is an attempt to shed light on Japanese business organization from a mentality perspective and thus to explain some characteristic attributes of the organization. "Mentality" provides, the basis for the mode of thought attributable to the nation. The "YAMATO SPIRIT", which is one of such mentalities and which is also the core concept of this thesis, is the Japanese mentality and thus is the basis for Japanese ways of thought and action. The Japanese mentality, in other words, the "YAMATO SPIRIT", is defined as "an effort to attain the identity of one with many through 'Nothingness'". As such, it manifests itself in the business field as well as in other aspects of Japanese life. In fact, this SPIRIT is one of the decisive elements in the business field, emerging as the Japanese business spirit. The Japanese business,spirit, in turn, takes various forms, such as the maxim "do your bit for your country" on the management side, Nenko wage system and Shushin Koyo employment system on the labor side, and the interdependence among firms, banks, and the Government. Furthermore, it is manifest in the business decision-making, functioning as a synthesizing element. Finally apart from the business organization, the Japanese mentality manifests itself with the existence and importance of the "Betriebswirtshaft" in the scholarly field of business in Japan. Again, this paper is an attempt to explain these characteristic attributes of Japanese business organization through Japanese mentality. The paper is composed of three Parts. In Part I, we shall look briefly, from a historical point of view, at the management and labor sides of Japanese business organization. This preliminary survey should present a good background for us to understand what the "YAMATO SPIRIT" is, and what its implications are in the Japanese business scene. In Part II, we shall discuss the three elements on which the "YAMATO SPIRT" is based, and then arrive at the definition of YAMATO SPIRIT by referring to Dr. Nishida's philosophy, and finally take up two distinguishing traits of Japanese mentality. The definition of YAMATO SPIRIT and its traits in this stage will be highly conceptual and abstract. Proceeding to Part III, however, YAMATO SPIRIT will take concrete forms; i.e., the forms of those above-mentioned characteristic attributes of the organization. In other words, it is in this Part that we shall view Japanese business organization from a mentality perspective. For this reason, much more emphasis has been put on this particular Part.
Heavy-baryon chiral perturbation theory approach to thermal neutron capture on ${}^{3}{He}$

description: The cross section for radiative thermal neutron capture on ${}^{3}He$ ($\He3 +n \to \He4 +γ$; known as the $hen$ reaction) is calculated based on heavy-baryon chiral perturbation theory. The relevant M1 operators are derived up to next-to-next-to-next-to-leading order (N${}^3$LO). The initial and final nuclear wave functions are obtained from the rigorous Faddeev-Yakubovski equations for five sets of realistic nuclear interactions. Up to N${}^3$LO, the M1 operators contain two low-energy constants, which appear as the coefficients of non-derivative two-nucleon contact terms. After determining these two constants using the experimental values of the magnetic moments of the triton and ${}^3 He$, we carry out a parameter-free calculation of the $hen$ cross section. The results are in good agreement with the data.

description: Australia’s colonial past and subsequent propagation of the White Australia policy in the Immigration Restriction Act of 1901 has meant that 'Whiteness' remains central to the national imaginary. Consequently, racial-colonial discourses axiomatically regulate scholarly and societal understandings of racial minorities through two unique but analogous debates – one focussed on the schism between Indigenous and non-Indigenous peoples; the other centred around immigration policy and multiculturalism (Curthoys, 2000). In the context of Australian education, there is a slowly developing collection of Critical Race Theory (CRT) scholarship that has addressed and challenged the inequities that pervade the Indigenous student experience (Ford, 2013; Vass, 2014, 2015); however, there has been much less momentum made with other racial minorities. Specifically, the experiences and voices of migrant pre-service and early career teachers from Asian backgrounds like myself, who have become increasingly prevalent in Australian education, remain largely absent from scholarship. In light of this, in this paper I use Asian CRT (AsianCrit) (Museus & Iftikar, 2013) to present an autoethnographic account of a migrant ‘Asian’ Australian high school teacher’s subjectivities, quests for solidarity and attempts at dealing with racial injustice across a range of White Australian classrooms.

description: We have carried out a search for radio emission at 820 MHz from six X-ray dim isolated neutron stars with the Robert C. Byrd Green Bank Radio Telescope. No transient or pulsed emission was found using fast folding, fast Fourier transform, and single-pulse searches. The corresponding flux limits are about 0.01 mJy for pulsed emission, depending on the integration time for the particular source and assuming a duty cycle of 2%, and 20 mJy for single dispersed pulses. These are the most sensitive limits to date on radio emission from X-ray dim isolated neutron stars. There is no evidence for isolated radio pulses, as seen in a class of neutron stars known as rotating radio transients. Our results imply that either the radio luminosities of these objects are lower than those of any known radio pulsars, or they could simply be long-period nearby radio pulsars with high magnetic fields beaming away from the Earth. To test the latter possibility, we would need around 40 similar sources to provide a 1 sigma probability of at least one of them beaming toward us. We also give a detailed description of our implementation of the Fast Folding Algorithm.

description: In the State of Queensland in Australia, Years 11 and 12 students can opt to study calculus based or non-calculus based mathematics. Calculus based mathematics subjects are a prerequisite for Science, Technology, Engineering and Mathematics (STEM), which has been identified as critically important for current and future productivity by the Australian government. The objective of this study was to identify broad trends in senior Queensland students’ participation in calculus and non-calculus based Mathematics purely from a statistical viewpoint using a large data set from the Queensland Curriculum and Assessment Authority (QCAA). To this end, trends in Years 11 and 12 students’ participation in calculus based Mathematics B and C, and non-calculus based Mathematics A and Prevocational Mathematics between 2010 and 2019 was investigated. The QCAA data was analysed using quantitative methods to identify trends in student participation in the various mathematics subject options. The data included number of schools, location, gender, indigenous or non-indigenous, residence status and number of students in different options. The results indicated that more male students opted for Mathematics B and C compared to females, and not all schools offered all options.

description: The static vacuum spherically symmetric solutions in massive gravity are obtained both analytically and numerically. The solutions depend on two parameters (integration constants): the mass M (or, equivalently, the Schwarzschild radius), and an additional parameter, the "scalar charge" S. At zero value of S and positive mass the standard Schwarzschild black hole solutions are recovered. Depending on the parameters of the model and the signs of M and S, the solutions may or may not have horizon. Those with the horizon describe modified black holes provided they are stable against small perturbations. In the analytically solvable example, the modified black hole solutions may have both attractive and repulsive (anti-gravitating) behavior at large distances. At intermediate distances the gravitational potential of a modified black hole may mimics the presence of dark matter. Modified black hole solutions are also found numerically in more realistic massive gravity models which are attractors of the cosmological evolution.

description: The equilibrium phase behavior of microphase-forming substances and models is notoriously difficult to obtain because of the extended metastability of the modulated phases. We develop a simulation method based on thermodynamic integration that avoids this problem and with which we obtain the phase diagram of the canonical three-dimensional axial next-nearest-neighbor Ising model. The equilibrium devil's staircase, magnetization, and susceptibility are obtained. The critical exponents confirm the XY nature of the disorder-modulated phase transition beyond the Lifshitz point. The results identify the limitations of various approximation schemes used to analyze this basic microphase-forming model.

description: The two-dimensional, periodic Lorentz gas, is the dynamical system corresponding with the free motion of a point particle in a planar system of fixed circular obstacles centered at the vertices of a square lattice in the Euclidian plane. Assuming elastic collisions between the particle and the obstacles, this dynamical system is studied in the Boltzmann-Grad limit, assuming that the obstacle radius $r$ and the reciprocal mean free path are asymptotically equivalent small quantities, and that the particle's distribution function is slowly varying in the space variable. In this limit, the periodic Lorentz gas cannot be described by a linear Boltzmann equation (see [F. Golse, Ann. Fac. Sci. Toulouse 17 (2008), 735--749]), but involves an integro-differential equation conjectured in [E. Caglioti, F. Golse, C.R. Acad. Sci. Sér. I Math. 346 (2008) 477--482] and proved in [J. Marklof, A. Strömbergsson, preprint arXiv:0801.0612], set on a phase-space larger than the usual single-particle phase-space. The main purpose of the present paper is to study the dynamical properties of this integro-differential equation: identifying its equilibrium states, proving a H Theorem and discussing the speed of approach to equilibrium in the long time limit. In the first part of the paper, we derive the explicit formula for a transition probability appearing in that equation following the method sketched in [E. Caglioti, F. Golse, loc. cit.].
