Cosmology is not a Renormalization Group Flow

description: A critical examination is made of two simple implementations of the idea that cosmology can be viewed as a renormalization group flow. Both implementations are shown to fail when applied to a massless, minimally coupled scalar with a quartic self-interaction on a locally de Sitter background. Cosmological evolution in this model is not driven by any RG screening of couplings but rather by inflationary particle production gradually filling an initially empty universe with a sea of long wavelength scalars.

description: We have developed the combination of an etching and deposition technique that enables the fabrication of locally gated graphene nanostructures of arbitrary design. Employing this method, we have fabricated graphene nanoconstrictions with local tunable transmission and characterized their electronic properties. An order of magnitude enhanced gate efficiency is achieved adopting the local gate geometry with thin dielectric gate oxide. A complete turn off of the device is demonstrated as a function of the local gate voltage. Such strong suppression of device conductance was found to be due to both quantum confinement and Coulomb blockade effects in the constricted graphene nanostructures.

description: The optical properties of bulk $λ/2$ GaN microcavities working in the strong light-matter coupling regime are investigated using angle-dependent reflectivity and photoluminescence at 5 K and 300 K. The structures have an Al$_{0.2}$Ga$_{0.8}$N/AlN distributed Bragg reflector as the bottom mirror and either an aluminium mirror or a dielectric Bragg mirror as the top one. First, the influence of the number of pairs of the bottom mirror on the Rabi splitting is studied. The increase of the mirror penetration depth is correlated with a reduction of the Rabi splitting. Second, the emission of the lower polariton branch is observed at low temperature in a microcavity containing two Bragg mirrors and exibiting a quality factor of 190. Our simulations using the transfer-matrix formalism, taking into account the real structure of the samples investigated are in good agreement with experimental results.

description: Farm management education is undergoing change in Australia, the United Kingdom and in the United States. Farm populations are changing and these changes have impacted upon farm management education. Reduction of resources, pressures from the broader community and advances in technology have led to restructuring ofprogrammes in all three countries. The dilemma faced by farm management educators is to maintain the emphasis on quality education while at the same time adjusting to change. The authors outline specific adjustments that have been made at the three institutions. The principles that will continue to guide the development of farm management education into the 21st Century are reliance on a systems approach, industry involvement and active learning by students.

description: Presentation of a three-year-project (1995-97) including the development, implementation and evaluation of an integrated quality and environmental management system after the international standards ISO 9002 and ISO 14001. The contents of a Joint Manual is described, the framework of an individual manual is outlined and the principles are discussed. It is concluded that it is possible to develop and apply a Joint Manual that outlines a framework for several farm enterprises with similar production. The concepts of quality and environmental management as described in the standards require individual systems for individual enterprises. In this case it is fulfilled by an individual quality and environmental manual, containing all the specific management tools required. A high degree of involvement of the farmer, his wife and his employees is absolutely necessary right from the beginning of the process because quality and environmental management highly affect the farmer’s attitudes.

description: Inelastic losses are crucial to a quantitative analysis of x-ray absorption spectra. However, current treatments are semi-phenomenological in nature. Here a first-principles, many-pole generalization of the plasmon-pole model is developed for improved calculations of inelastic losses. The method is based on the GW approximation for the self-energy and real space multiple scattering calculations of the dielectric function for a given system. The model retains the efficiency of the plasmon-pole model and is applicable both to periodic and aperiodic materials over a wide energy range. The same many-pole model is applied to extended GW calculations of the quasiparticle spectral function. This yields estimates of multi-electron excitation effects, e.g., the many-body amplitude factor $S_0^2$ due to intrinsic losses. Illustrative calculations are compared with other GW calculations of the self-energy, the inelastic mean free path, and experimental x-ray absorption spectra.

title: Non-conventional synthesis and characterization of selected MAX phases and antiperovskite materials
Creators: name: Kubitza, Niels
Publisher: name: UNSPECIFIED
Year: 2023

description: In this work, efficient, non-conventional solid-state methods were applied for the synthesis of selected MAX phases and antiperovskite materials. In the context of MAX phases, three hitherto unknown M-site solid-solution phases, as well as three new X-site solid-solution phases were prepared and comprehensively characterized. For the synthesis of the M-site solid-solution phases, the rapid microwave heating method was applied and led to the synthesis of (V1-xCrx)2GaC, (V1-xMnx)2GaC, and (Cr1-xMox)2GaC, respectively. Particularly, the synthesis of (V1-xCrx)2GaC provides a new approach to reach magnetic ordering in MAX phases since this system was identified as an itinerant Pauli paramagnet which is nearly magnetically ordered. In terms of the X-site solid solution phases, new synthesis approaches were developed to synthesize underrepresented nitride and carbonitride MAX phases by combining conventional/non-conventional heating methods with solvent-based precursor synthesis approaches (e.g., sol-gel synthesis, synthesis in liq. NH3). In the field of antiperovskites, it was concentrated on the magnetocaloric interesting phase Mn3GaC. Here, for the first time, a citric acid-based sol-gel approach was applied resulting in a highly phase pure product combined with a significant reduction of the reaction time.
A simple randomized algorithm for sequential prediction of ergodic time series

description: We present a simple randomized procedure for the prediction of a binary sequence. The algorithm uses ideas from recent developments of the theory of the prediction of individual sequences. We show that if the sequence is a realization of a stationary and ergodic random process then the average number of mistakes converges, almost surely, to that of the optimum, given by the Bayes predictor. The desirable finite-sample properties of the predictor are illustrated by its performance for Markov processes. In such cases the predictor exhibits near optimal behavior even without knowing the order of the Markov process. Prediction with side information is also considered.
Unbounded Fredholm modules and double operator integrals

description: In noncommutative geometry one is interested in invariants such as the Fredholm index or spectral flow and their calculation using cyclic cocycles. A variety of formulae have been established under side conditions called summability constraints. These can be formulated in two ways, either for spectral triples or for bounded Fredholm modules. We study the relationship between these by proving various properties of the map on unbounded self adjoint operators $D$ given by $f(D)=D(1+D^2)^{-1/2}$. In particular we prove commutator estimates which are needed for the bounded case. In fact our methods work in the setting of semifinite noncommutative geometry where one has $D$ as an unbounded self adjoint linear operator affiliated with a semi-finite von Neumann algebra $\aM$. More precisely we show that for a pair $D,D_0$ of such operators with $D-D_0$ a bounded self-adjoint linear operator from $\aM$ and $ ({\bf 1}+D_0^2)^{-1/2}\in \sE$, where $\sE$ is a noncommutative symmetric space associated with $\aM$, then $$ \Vert f(D) - f (D_0) \Vert_{\sE} \leq C\cdot \Vert D-D_0\Vert_{\aM}. $$ This result is further used to show continuous differentiability of the mapping between an odd $\sE$-summable spectral triple and its bounded counterpart.

description: We investigate the low-lying excited states of the spin J ferromagnetic XXZ chain with Ising anisotropy Delta and kink boundary conditions. Since the third component of the total magnetization, M, is conserved, it is meaningful to study the spectrum for each fixed value of M. We prove that for J>= 3/2 the lowest excited eigenvalues are separated by a gap from the rest of the spectrum, uniformly in the length of the chain. In the thermodynamic limit, this means that there are a positive number of excitations above the ground state and below the essential spectrum.

Charge density wave breakdown in a heterostructure with electron-phonon coupling

description: Understanding the influence of vibrational degrees of freedom on transport through a heterostructure poses considerable theoretical and numerical challenges. In this work, we use the density-matrix renormalization group (DMRG) method together with local basis optimization (LBO) to study the half-filled Holstein model in the presence of a linear potential, either isolated or coupled to tight-binding leads. In both cases, we observe a decay of charge-density-wave (CDW) states at a sufficiently strong potential strength. Local basis optimization selects the most important linear combinations of local oscillator states to span the local phonon space. These states are referred to as optimal modes. We show that many of these local optimal modes are needed to capture the dynamics of the decay, that the most significant optimal mode on the initially occupied sites remains well described by a coherent-state typical for small polarons, and that those on the initially empty sites deviate from the coherent-state form. Additionally, we compute the current through the structure in the metallic regime as a function of voltage. For small voltages, we reproduce results for the Luttinger parameters. As the voltage is increased, the effect of larger electron-phonon coupling strengths becomes prominent. Further, the most significant optimal mode remains almost unchanged when going from the ground state to the current-carrying state in the metallic regime.

Our calculations of the lifetimes of the metastable $6d$ states using the relativistic coupled-cluster theory suggest that they are sufficiently long for Ra$^+$ to be considered as a potential candidate for an atomic clock. This is further corroborated by our studies of the hyperfine interactions, dipole and quadrupole polarizabilities and quadrupole moments of the appropriate states of this system.

Mass-luminosity relation and pulsational properties of Wolf-Rayet stars
Creators: name: Fadeyev, Yu. A.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Evolution of Population I stars with initial masses from 70M_\odot to 130M_\odot is considered under various assumptions on the mass loss rate \dot M. The mass-luminosity relation of W-R stars is shown to be most sensitive to the mass loss rate during the helium burning phase \dot M_{3α}. Together with the mass-luminosity relation obtained for all evolutionary sequences several more exact relations are determined for the constant ratio f_{3α}=\dot M/\dot M_{3α} with 0.5 \le f_{3α} \le 3. Evolutionary models of W-R stars were used as initial conditions in hydrodynamic computations of radial nonlinear stellar oscillations. The oscillation amplitude is larger in W-R stars with smaller initial mass or with lower mass loss rate due to higher surface abundances of carbon and oxygen. In the evolving W-R star the oscillation amplitude decreases with decreasing stellar mass M and for M < 10M_\odot the sufficiently small nonlinear effects allow us to calculate the integral of the mechanical work W done over the pulsation cycle in each mass zone of the hydrodynamical model. The only positive maximum on the radial dependence of W is in the layers with temperature of T\sim 2e5K where oscillations are excited by the iron Z--bump kappa-mechanism. Radial oscillations of W-R stars with mass of M > 10M_\odot are shown to be also excited by the kappa-mechanism but the instability driving zone is at the bottom of the envelope and pulsation motions exist in the form of nonlinear running waves propagating outward from the inner layers of the envelope.

description: In this paper the author draws on recent study offamily farming and agribusiness trends in Europe, USA, New Zealand and Australia. He reviews the characteristics of traditional family farms in Western countries. He then indicates major global trends which are impacting on the ways in which agriculture and the food andfibre system operate. The major cultural and business changes which should be considered by each farm family are then reviewed. With reference to family farm case studies he indicates how some successful farm families are responding to the demands of the new globalised food and fibre system. The author concludes that an exciting and rewarding new era in family farming is emerging but only for those farm families willing to challenge their traditional sacred cows.

Year: 1997
Subjects: Farm Management

description: After working for one year in a Russian-German project for „ Restructuring Large Agricultural Firms in the Region of Vladimir the author has made an in-depth analysis of the current economic situation of farms in Russia. The goal of the project is to develop approaches to restructuring farms, to build up an extension service and to give advice on regional agricultural policy. Accordingly, a series of adjustments in the management of the pilot farms involved in the project was developed Areas of suggested change in farm management include reconsidering the legal form of the enterprises, evaluating competence and responsibility of the leaders and improving information flow and communication between the owners andfarm workers. The economic situation for Russian farms has got so difficult that fundamental adjustment to the new market economy is inevitable. Therefore technical and management improvements are necessary, and deconcentration and decentralization of the farms is imperative. The cost of these restructuring efforts must be borne by the farms themselves, which makes the whole process even more difficult. This makes great demands on the managers of the farms.

Expressive uses of word order in Iliad
Creators: name: Stiles, Lewis
Publisher: name: University of British Columbia
Year: 2010

description: Homer uses some poetic effects in the Iliad which have not "been properly studied. These include enjambement, balance, triadic structure, assonance, rhyme and repetition with variation. All of them are dependent on word order, and are associated to a large extent with enjambement. In this thesis, each of these special effects is discussed in the Introduction, In the body of the thesis, they are examined and discussed in detail as they occur in Iliad I. This is done in three ways. First, an Annotated Text indicates details of assonance and metre which are too numerous to present in any other way, as well as many of the other effects. Second, a Translation serves as a gloss on the Text and provides a fixed record of word order and word choice useful for isolating the repetitions, as well as many of the other effects, in the book. Finally, a Commentary discusses specific lines and the effects found in them in detail, and presents arguments for new interpretations of the poetry which arise from these discussions.

description: We present results on the star cluster properties from a series of high resolution smoothed particles hydrodynamics (SPH) simulations of isolated dwarf galaxies as part of the GRIFFIN project. The simulations at sub-parsec spatial resolution and a minimum particle mass of 4 $\mathrm{M_\odot}$ incorporate non-equilibrium heating, cooling and chemistry processes, and realise individual massive stars. All the simulations follow feedback channels of massive stars that include the interstellar-radiation field, that is variable in space and time, the radiation input by photo-ionisation and supernova explosions. Varying the star formation efficiency per free-fall time in the range $ε_\mathrm{ff}$ = 0.2 - 50$\%$ neither changes the star formation rates nor the outflow rates. While the environmental densities at star formation change significantly with $ε_\mathrm{ff}$, the ambient densities of supernovae are independent of $ε_\mathrm{ff}$ indicating a decoupling of the two processes. At low $ε_\mathrm{ff}$, more massive, and increasingly more bound star clusters are formed, which are typically not destroyed. With increasing $ε_\mathrm{ff}$ there is a trend for shallower cluster mass functions and the cluster formation efficiency $Γ$ for young bound clusters decreases from $50 \%$ to $\sim 1 \%$ showing evidence for cluster disruption. However, none of our simulations form low mass ($< 10^3$ $\mathrm{M_\odot}$) clusters with structural properties in perfect agreement with observations. Traditional star formation models used in galaxy formation simulations based on local free-fall times might therefore not be able to capture low mass star cluster properties without significant fine-tuning.

description: Orca (Orcinus orca) is known for complex vocalisation. Their social structure consists of pods and clans sharing unique dialects due to geographic isolation. Sound type repertoires are fundamental for monitoring orca populations and are typically created visually and aurally. An orca pod occurring in the Ligurian Sea (Pelagos Sanctuary) in December 2019 provided a unique occasion for long-term recordings. The numerous data collected with the bottom recorder were analysed with a traditional human-driven inspection to create a repertoire of this pod and to compare it to catalogues from different orca populations (Icelandic and Antarctic) investigating its origins. Automatic signal detection and cross-correlation methods (R package warbleR) were used for the first time in orca studies. We found the Pearson cross-correlation method to be efficient for most pairwise calculations (> 85%) but with false positives. One sound type from our repertoire presented a high positive match (range 0.62-0.67) with one from the Icelandic catalogue, which was confirmed visually and aurally. Our first attempt to automatically classify orca sound types presented limitations due to background noise and sound complexity of orca communication. We show cross-correlation methods can be a powerful tool for sound type classification in combination with conventional methods.

description: The spatiotemporal dynamics of Lyapunov vectors (LVs) in spatially extended chaotic systems is studied by means of coupled-map lattices. We determine intrinsic length scales and spatiotemporal correlations of LVs corresponding to the leading unstable directions by translating the problem to the language of scale-invariant growing surfaces. We find that the so-called 'characteristic' LVs exhibit spatial localization, strong clustering around given spatiotemporal loci, and remarkable dynamic scaling properties of the corresponding surfaces. In contrast, the commonly used backward LVs (obtained through Gram-Schmidt orthogonalization) spread all over the system and do not exhibit dynamic scaling due to artifacts in the dynamical correlations by construction.

description: Time series measurements in 2H-NbS$_2$ crystal had unravelled a drive induced transition wherein the critical current (Ic) changes from a low to a high Ic jammed vortex state, via a negative differential resistance (NDR) transition. Here, using multiple current (I) - voltage (V) measurement cycles, we explore the statistical nature of observing the NDR transition in the free-flux-flow (FF) regime in a single crystal of 2H-NbS$_2$. The probability of observing the NDR transition always remains finite for a vortex state created with either fast or slow rate of magnetic field. The probability of observing the NDR transition in the FF regime is found to systematically increase with magnetic field (B) in weak collective pinning regime. In the strong pinning regime, the said probability becomes B-independent. We show that the higher Ic state is unique and cannot be accessed via any conventional route. While the I-V curves do not distinguish between zero field cooled (ZFC) and field cooled (FC) modes of preparing the vortex state, the probability for observing an NDR transition has different B-dependences for the vortex matter prepared in the ZFC and FC modes. We find that the NDR occurs in a high dissipation regime, where the flow resistivity is well above the theoretical value expected in the FF regime. We understand our results on the basis of a rapid drop in vortex viscosity at high drives in 2H-NbS$_2$, which triggers a rapid increase in the vortex velocity and reorganization in the moving vortex matter leading to a dynamical unstable vortex flow. This dynamical instability leads to the NDR transition into a high entropy vortex state with high Ic.
title: The Covid‐19 containment effects of public health measures: A spatial difference‐in‐differences approach

description: The paper studies the containment effects of public health measures to curb the spread of Covid‐19 during the first wave of the pandemic in spring 2020 in Germany. To identify the effects of six compound sets of public health measures, we employ a spatial difference‐in‐differences approach. We find that contact restrictions, mandatory wearing of face masks and closure of schools substantially contributed to flattening the infection curve. The significance of the impact of restaurant closure does not prove to be robust. No incremental effect is evidenced for closure of establishments and the shutdown of nonessential retail stores.

description: In this paper, we carry out multiwavelength observations of three recurring jets on 2014 November 7. The jets originated from the same region at the edge of AR 12205 and propagated along the same coronal loop. The eruptions were generated by magnetic reconnection, which is evidenced by continuous magnetic cancellation at the jet base. The projected initial velocity of the jet2 is 402 km s. The accelerations in the ascending and descending phases of jet2 are not consistent, the former is considerably larger than the value of solar gravitational acceleration at the solar surface, while the latter is lower than solar gravitational acceleration. There are two possible candidates of extra forces acting on jet2 during its propagation. One is the downward gas pressure from jet1 when it falls back and meets with jet2. The other is the viscous drag from the surrounding plasma during the fast propagation of jet2. As a contrast, the accelerations of jet3 in the rising and falling phases are constant, implying that the propagation of jet3 is not significantly influenced byextra forces.
title: The Red‐Shirt‐sided underground movements in Thai politics: resistant operations towards the Mysterious Land

Subjects: subject: Thai Underground Movement, Thai Red-Shirt Movement, Marxism and Social Movement, Historical Materialism, Uneven and Combined Development.

description: This thesis studies the Red-Shirt-sided underground movement that began its political role in the Thai political scene beginning with the 2010 repression of the Red-Shirt movement by Thai state. This movement has three main characteristics. Firstly, this underground movement has more radical political ideas than the previous Red-Shirt movement. Secondly, besides Red Shirts supporters, there are other people join this subsequent movement, albeit never participated in Red-Shirt activities but ‘sided’ with its direction. Finally, this movement used underground methods to avoid being arrested and repressed by the Thai government. The study used the two Marxist ideas – historical materialism and the uneven and combined development (UCD) – and some social movement theories such as Charles Tilly’s work to create a conceptual framework. According to this framework and the main data obtained from interviewing activists and collecting online material, the results of this study show, firstly, the Red-Shirt-sided underground movement is one of the results of the development of the capitalist mode of production in Thai society under the conditions of UCD. The main groups in the Thai ruling class which led the transition from a pre-capitalist to a capitalist mode of production in Thai society had been able to retain their power continually, even while facing difficulties and challenges on both domestic and international level. Although this made the Thai ruling class very powerful, the intrinsic expansion of capitalist development and political conditions led to crucial social conflicts and the uprising of mass movements in the late 2000s. The brutal repression by the state caused some dissidents to adopt radical ideas and this eventually formed the underground movement. Second, although the early ideas and actions of the underground movement derived from the previous movements, the dialectic relationships both within the movement and between the movement and other social institutions led to the reproduction of ideas and actions but with differing qualities. Finally, this movement made changes both within the movement and to the impact on external social institutions. Some underground groups could expand their number of followers and arrange activities in Thailand. However, Thai authorities repressed underground groups in many ways including by arrest, and allegedly, by abduction and assassination.
Managerial Reforms for a Russian Dairy Farm

Subjects: Farm Management

description: Russia is attempting to move from collectivized command based agriculture to an industry based on private ownership and market forces. The transformation of command economies has, however, proved extremely complex. This paper outlines the difficulties associated with reforming management in the Russian dairy industry. The current state of dairy technology is discussed and the former managerial system outlined. The managerial difficulties faced by both small scale private dairy farmers and the former collective/state farms are discussed. It appears that past investments in large scale facilities and the legacy of a management structure which failed to treat dairying as an interactive, interdependent system will constrain the modernization of the Russian dairy industry, at least over the intermediate term.

Localized Modes in Type II and Heterotic Singular Calabi-Yau Conformal Field Theories

Year: 2008

description: We consider type II and heterotic string compactifications on an isolated singularity in the noncompact Gepner model approach. The conifold-type ADE noncompact Calabi-Yau threefolds, as well as the ALE twofolds, are modeled by a tensor product of the SL(2,R)/U(1) Kazama-Suzuki model and an N=2 minimal model. Based on the string partition functions on these internal Calabi-Yaus previously obtained by Eguchi and Sugawara, we construct new modular invariant, space-time supersymmetric partition functions for both type II and heterotic string theories, where the GSO projection is performed before the continuous and discrete state contributions are separated. We investigate in detail the massless spectra of the localized modes. In particular, we propose an interesting three generation model, in which each flavor is in the 27+1 representation of E6 and localized on a four-dimensional space-time residing at the tip of the cigar.

The opinions of the adult deaf community towards methods of communication in the education of deaf children
Creators: name: Stewart, David Alan
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of the study was to survey the adult Deaf and document their viewpoints on appropriate methods of communication for deaf children. A review of the literature revealed that different methods were being used in the education of the Deaf. Sign language is one of the methods that is presently being used as a means for instruction. However, it is noted that the sign language utilized by the Deaf within the Deaf community is different from signs being used in the classroom. Furthermore, input from the Deaf community is not a factor in determining how signs are to be incorporated into the framework of our educational system. These findings gave directions for a survey of the Deaf community. A questionnaire was designed, pilot-tested, and then administered to 162 Deaf adults in the Greater Vancouver metropolitan area. The questions were concerned with viewpoints on sign language and its role in the development of a deaf child's communication. Special attention was given to the comparative roles of Deaf signs and English signs. Data analysis revealed the overall expectations of the Deaf community of deaf children's methods of communication. The consensus of the Deaf was that sign language should be learned at an early age and before speech; language should be acquired bilingually with Deaf signs and English signs forming the basis of the two languages; and deaf children should be able to obtain a bilingual education and have the opportunity to be able to converse in either language with teachers of the Deaf. Finally, members of the Deaf community should be involved in the formulation and implementation of policies in education of the Deaf.
