The tentative leap forward : reforms and experiments in basic level Chinese industrial management policies, 1977-1979
Creators: name: Parrish, Geoffrey Leal
Publisher: name: University of British Columbia
Year: 2010

description: This thesis addresses two major topics. The first is the changes in national policy concerning basic level industrial management which accompanied the change in political leadership in the People's Republic of China after the death of Mao Zedong. This paper examines the nature and extent of such policy changes at a national level during the period 1977-1979. Secondly, this paper seeks to identify basic level industrial management policies formulated at a sub-national (generally provincial) level which differed in either timing or policy content from those being promoted nationally. The primary source of reference material for this thesis is the compilations of transcriptions of national, provincial, and local radio broadcasts and announced periodical articles published by the Foreign Broadcast Information Service. Approximately 750 daily reports published during the years 1977-1979 were examined in order to compile both accounts of relevant policy changes at the national level and discrepancies among policy descriptions and developments at the provincial and local levels. These materials were supplemented by numerous articles by outside observers, in order to provide additional information and a broader perspective than that offered by the Chinese government-originated material. The paper identifies two distinct categories - organizational reforms and the reintroduction of material incentives - of major changes in the policies of management of individuals, collectives, and industries during this period, in order to improve productivity. Details of the evolution of these policies and their presentation in the Chinese media are given. The paper then examines variations in these policies among different provinces and areas, and identifies three areas - Sichuan province, Guangdong province, and the major cities of Shanghai, Beijing, and Tianjin - where reforms tended to be more progressive than in the country at large and might serve as models or experiments in new policies being considered for national adoption. Finally, managerial policies promulgated during this time are reviewed and analyzed for their ability to meet the needs of the rapid industrialization desired by Chinese leadership. Three potential difficulties are identified: the political opposition of some factions to new or broader reforms; problems in the reconciliation of a greater role for market forces with the needs of a centralized, planned economy; and the difficulty in adapting or revising the present strategy to accommodate changing or unexpected circumstances.

description: GRB051022 was undetected to deep limits in early optical observations, but precise astrometry from radio and X-ray showed that it most likely originated in a galaxy at z~0.8. We report radio, optical, near infra-red and X-ray observations of GRB051022. Using the available X-ray and radio data, we model the afterglow and calculate the energetics of the afterglow, finding it to be an order of magnitude lower than that of the prompt emission. The broad-band modeling also allows us to precisely define various other physical parameters and the minimum required amount of extinction, to explain the absence of an optical afterglow. Our observations suggest a high extinction, at least 2.3 magnitudes in the infrared (J) and at least 5.4 magnitudes in the optical (U) in the host-galaxy restframe. Such high extinctions are unusual for GRBs, and likely indicate a geometry where our line of sight to the burst passes through a dusty region in the host that is not directly co-located with the burst itself.

description: We examine the electronic width ratios of Upsilon resonances below the BBbar threshold by means of an effective (Cornell-type) QCD potential incorporating 1/m_b corrections obtained from a prior fit to the bottomonium spectrum. From our analysis we conclude that the Upsilon(2S) and Upsilon(3S) states should belong to the strong-coupling (nonperturbative) regime while the Upsilon(1S) state should belong to the weak-coupling (perturbative) regime, in agreement with a previous study based on radiative decays.

A novel method for evaluating the critical nucleus and the surface tension in systems with first order phase transition
Creators: name: Cammarota, Chiara
name: Cavagna, Andrea
Publisher: name: arXiv
Year: 2007
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We introduce a novel method for calculating the size of the critical nucleus and the value of the surface tension in systems with first order phase transition. The method is based on classical nucleation theory, and it consists in studying the thermodynamics of a sphere of given radius embedded in a frozen metastable surrounding. The frozen configuration creates a pinning field on the surface of the free sphere. The pinning field forces the sphere to stay in the metastable phase as long as its size is smaller than the critical nucleus. We test our method in two first-order systems, both on a two-dimensional lattice: a system where the parameter tuning the transition is the magnetic field, and a second system where the tuning parameter is the temperature. In both cases the results are satisfying. Unlike previous techniques, our method does not require an infinite volume limit to compute the surface tension, and it therefore gives reliable estimates even by using relatively small systems. However, our method cannot be used at, or close to, the critical point, i.e. at coexistence, where the critical nucleus becomes infinitely large.

Intermittent Signals and Planetary Days in SETI

description: Interstellar signals might be intermittent for many reasons, such as targeted sequential transmissions, or isotropic broadcasts that are not on continuously, or many other reasons. The time interval between such signals would be important, because searchers would need to observe for long enough to achieve an initial detection and possibly determine a period. This article suggests that: (1) the power requirements of interstellar transmissions could be reduced by orders of magnitude by strategies that would result in intermittent signals, and (2) planetary rotation might constrain some transmissions to be intermittent and in some cases to have the period of the source planet, and (3) signals constrained by planetary rotation might often have a cadence in the range of 10-25 hours, if the majority of planets in our solar system are taken as a guide. Extended observations might be needed to detect intermittent signals and are rarely used in SETI but are feasible, and seem appropriate when observing large concentrations of stars or following up on good candidate signals.

Conductance enhancement due to the resonant tunneling into the subgap vortex core states in normal metal/superconductor ballistic junctions
Creators: name: Silaev, M. A.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: We investigate the low-energy quantum transport in the ballistic normal metal-insulator -superconductor junction in the presence of magnetic field creating Abrikosov vortices in the superconductor. Within the Bogolubov- de Gennes theory we show that the presence of the subgap quasiparticle states localized within the vortex cores near the junction interface leads to the strong resonant enhancement of the Andreev reflection probability, and the normal-to supercurrent conversion. The corresponding increase of the charge conductance of the junction is determined by the distance from the vortex chain to the junction interface, which can be controlled by the applied magnetic field. The effect that we study provides a tool for probing the vortex core states by the measurements of charge transport across the applied magnetic field.

Relativistic Fractional-Dimension Gravity

description: This paper presents a relativistic version of Newtonian Fractional-Dimension Gravity (NFDG), an alternative gravitational model recently introduced and based on the theory of fractional-dimension spaces. This extended version - Relativistic Fractional-Dimension Gravity (RFDG) - is based on other existing theories in the literature and might be useful for astrophysical and cosmological applications. In particular, we review the mathematical theory for spaces with non-integer dimensions and its connections with the non-relativistic NFDG. The Euler-Lagrange equations for scalar fields can also be extended to spaces with fractional dimensions, by adding an appropriate weight factor, and then can be used to generalize the Laplacian operator for rectangular, spherical, and cylindrical coordinates. In addition, the same weight factor can be added to the standard Hilbert action in order to obtain the field equations, following methods used for scalar-tensor models of gravity, multi-scale spacetimes, and fractional gravity theories. We then apply the field equations to standard cosmology and to the Friedmann-Lemaître-Robertson-Walker metric. Using a suitable weight $v_{t}\left(t\right)$, depending on the synchronous time $t$ and on a single time-dimension parameter $α_{t}$, we extend the Friedmann equations to the RFDG case. This allows for the computation of the scale factor $a\left(t\right)$ for different values of the fractional time-dimension $α_{t}$ and the comparison with standard cosmology results. Future additional work on the subject, including studies of the cosmological late-time acceleration, type Ia supernovae data, and related dark energy theory will be needed to establish this model as a relativistic alternative theory of gravity.

Control and planning : a distinction with a difference, a case study of the central Okanagan
Creators: name: White, Richard Henry
Publisher: name: University of British Columbia
Year: 2010

description: This thesis studies the decisions of the Kelowna, B.C. City Council to trace the development of land use control and planning in the central Okanagan. Initially a review of planning literature is conducted which supports the distinction between land use control and land use planning. For the purpose of this thesis, "land use control" is defined as reactive municipal by-laws or resolutions which restrict development on a program or project basis, and "land use planning" is defined as a municipal policy process which is goal oriented guiding the long term development of the community. While early Canadian planning theorists and practitioners advocated land use controls only as part of an overall planning process, a review of planning history shows that Canadian municipalities have often favoured land use controls to the exclusion of land use planning initiatives. Similarly, the case study shows that Kelowna Council adopted land use control by-laws eschewing a committment to land use planning. The thesis shows that, although the literature provides no consensus on the underlying political or economic rationale, it contends that the local political process dominates land control and planning. The case study supports this contention and provides evidence to show that land use controls were politically popular while land use planning was not. The study argues that the local political process does not support goals oriented, policy based planning because it limits political power and flexibility while requiring political commitment.
On the Origin of Rapid Flares in TeV Blazars
Creators: name: Levinson, Amir
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The rapid variability of the VHE emission reported for some TeV blazars implies Doppler factors well in excess of those inferred from superluminal motions and unification schemes. We propose that those extreme flares may result from radiative deceleration of blobs on scales where local dissipation occurs. The minimum jet power estimated from the resolved synchrotron emission on VLBI scales appears to be consistent with this model. It is shown that if the energy distribution of nonthermal electrons accelerated locally in the blob is reasonably flat, then a background radiation field having a luminosity in the range 10$^{41}-10^{42}$ erg s$^{-1}$ can give rise to a substantial deceleration of the blob, but still be transparent enough to allow the TeV $γ$-rays thereby produced to escape the system.

Pion superfluid phase transition at finite isospin chemical potential
Creators: name: Xu, Shu-Sheng
Publisher: name: arXiv
Year: 2021
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The pion superfluidity phase transition at $T-μ_I$ and $μ_q-μ_I$ planes are studied in the framework of Dyson-Schwinger equations. The rainbow truncation and Gaussian effective gluon propagator are employed to calculate pion condensate, $\langleπ\rangle$, as a function of $μ_I$ at finite $T$ and $μ_q$. At $T=(0, 80, 113, 120)$~MeV, the $\langleπ\rangle$ keeps zero when $μ_I$ is less than a critical value $μ_{Ic}(T)$. The $\langleπ\rangle$ at $T=113$~MeV agrees with the lattice QCD result. At the $T-μ_I$ plane, the pion superfluid phase appears at low temperature and high isospin chemical potential region. At finite $μ_q$, $\langleπ\rangle$ varying with $μ_I$ almost coincide for $μ_q<400$~MeV. At $μ_q-μ_I$ plane, the pion superfluid phase appears at $μ_I\gtrsim m_π$ when $μ_q<400$~MeV.

Hydrodynamics of laser accelerated foils
Creators: name: Josin, Gary M.
Publisher: name: University of British Columbia
Year: 2010

description: A ruby laser system has been constructed and characterized to check the applicability of a diagnostic method which extracts all the hydrodynamic parameters without any knowledge of the microscopic physics. Our diagnostic method is not yet employable since strong shock waves are not generated with the available laser system. However the experimental results agree with a general heat wave model which is based on a universal heating characteristic. Furthermore the experimental results are consistent with the well documented Medusa hydrocode. It is of interest that for laser plasmas a universal heating characteristic exists from which the exhaust temperature for the laser plasma can be predicted from the laser intensity alone.

description: In the paper, combined bimodal microscopic visualization of biological objects based on reflection-mode optical and photoacoustic measurements was presented. Gasmicrophone configuration was chosen for the registration of photothermal response. Precise positioning of the scanning laser beam with modulated intensity was performed employing acousto-optic deflectors. Photoacoustic images are shown to give complementary details to the optical images obtained in the reflected light. Specifically, the photoacoustic imaging mode allows much better visualization of the features with enhanced heat localization due to the reduced heat outflow. For example, the application of the photoacoustic imaging mode was especially successful to visualize Drosophila fly's micro-hairs. Furthermore, the photoacoustic image quality was shown to be adjusted through modulation frequency.

description: We use transient absorption spectroscopy with circularly polarized x-rays to detect laser-excited hole states below the Fermi level and compare their dynamics with that of unoccupied states above the Fermi level in ferromagnetic [Co/Pd] multilayers. While below the Fermi level an instantaneous and significantly stronger demagnetization is observed, above the Fermi level the demagnetization is delayed by 35+/-10 fs. This provides a direct visualization of how ultrafast demagnetization proceeds via initial spin-flip scattering of laser-excited holes to the subsequent formation of spin waves.

description: The life of Hacı Bektaş Veli and the historical course of the Bektashi order are among the subjects that have been the focus of attention of many researchers inspecialized fields such as history, history of religions, literature and archeology in Iran since 1976. As a result of a search on the Internet, more than 50 written works, mas?ter’s and doctoral theses, books and articles titled “Bektashi” and “Bektashiyye” were found. Some of these articles and books have been extracted from theses, and some of them are translations of the work of non-Iranian researchers. Some of the works are duplicates and 29 of them are from non-Iranian authors. The studies selected for evaluation in this study are limited to those prepared and published in accordance with scientific and research techniques. In order to investigate the nature and importance of this topic among Iranian researchers and the ways in which researchers perceive the issue, those published under 29 research and review article titles were analyzed. The results of the analysis of these works show the following: the historical context of the formation and establishment of the Bektashi Sect and its active role in the social and political movements in the affected regions, understanding and assimilation of the ideas and belief elements of other religions and different cultures with which the religious philosophy of the sect is compatible, belief partnership with Twelver Shiism, this The influence of the sect on the spread of Islam, the customs and traditions of the sect, and the written works of this sect are gathered under the headings that attract the most attention

description: As a well-motivated dark matter candidate, axions can be detected through the axion-photon resonant conversion in the magnetospheres of magnetic white dwarf stars or neutron stars. In this work, we utilize Omega Centauri, which is the largest globular cluster in the Milky Way and is suggested to be the remnant core of a dwarf galaxy, to probe the axion dark matter through radio signals that originate from all the neutron stars and magnetic white dwarf stars in it. With 100 hours of observation, the combination of SKA phase 1 and LOFAR can effectively probe the parameter space of the axion-photon coupling $g_{aγ}$ up to $10^{-14}\sim 10^{-15}~\text{GeV}^{-1}$ for the axion mass range of $0.1\sim 30 ~μ\text{eV}$. Depending on the choice of neutron star evolution model, this limitation is two or three and a half orders of magnitude higher than that of the single neutron star or magnetic white dwarf.

description: The recent growth in data volumes produced by modern electron microscopes requires rapid, scalable, and flexible approaches to image segmentation and analysis. Few-shot machine learning, which can richly classify images from a handful of user-provided examples, is a promising route to high-throughput analysis. However, current command-line implementations of such approaches can be slow and unintuitive to use, lacking the real-time feedback necessary to perform effective classification. Here we report on the development of a Python-based graphical user interface that enables end users to easily conduct and visualize the output of few-shot learning models. This interface is lightweight and can be hosted locally or on the web, providing the opportunity to reproducibly conduct, share, and crowd-source few-shot analyses.

description: Using new Chandra X-ray observations and existing XMM-Newton X-ray and Hubble far ultraviolet observations, we aim to detect and identify the faint X-ray sources belonging to the Galactic globular cluster NGC 2808 in order to understand their role in the evolution of globular clusters. We present a Chandra X-ray observation of the Galactic globular cluster NGC 2808. We classify the X-ray sources associated with the cluster by analysing their colours and variability. Previous observations with XMM-Newton and far ultraviolet observations with the Hubble Space Telescope are re-investigated to help identify the Chandra sources associated with the cluster. We compare our results to population synthesis models and observations of other Galactic globular clusters. We detect 113 sources, of which 16 fall inside the half-mass radius of NGC 2808 and are concentrated towards the cluster core. From statistical analysis, these 16 sources are very likely to be linked to the cluster. We detect short-term (1 day) variability in X-rays for 7 sources, of which 2 fall inside the half-mass radius, and long-term (28 months) variability for 10 further sources, of which 2 fall inside the half-mass radius. Ultraviolet counterparts are found for 8 Chandra sources in the core, of which 2 have good matching probabilities and have ultraviolet properties expected for cataclysmic variables. We find one likely neutron star-quiescent low-mass X-ray binary and 7 cataclysmic variable candidates in the core of NGC 2808. The other 8 sources are cataclysmic variable candidates, but some could possibly be active binaries or millisecond pulsars. We find a possible deficit of X-ray sources compared to 47 Tuc which could be related to the metallicity content and the complexity of the evolution of NGC 2808.

description: Relativistic viscous hydrodynamic fits to RHIC data on the centrality dependence of multiplicity, transverse and elliptic flow for sqrt{s}=200 GeV Au+Au collisions are presented. For Glauber-type initial conditions, while data on integrated v_2 is consistent with a ratio of viscosity over entropy density up to eta/s=0.16, data on minimum bias v_2 seems to favor a much smaller viscosity over entropy ratio, below the bound from the AdS/CFT conjecture. Some caveats on this result are discussed.

description: We investigate Rindler's frame measurements. From its perspective, we found a geometric/gravitational interpretation of speed of light, mass and uncertainty principle. This can be interpreted as measurements of a black hole universal clock. This lead to an emergence of a timeless state of gravity in a mathematically consistent way. In other words, space my be a frozen time.

description: Expressions for the quantum fluctuations of energy density have been derived for the subsystems consisting of hot relativistic gas of particles with spin-$\frac{1}{2}$ and mass $m$. Our expressions for the fluctuation depend on the form of energy-momentum tensor which in turn depend on the choice of pseudo-gauge. These results suggest that quantum fluctuations of energy should be considered seriously in the case of the very small thermodynamic systems.

description: Electromagnetic dipole absorption cross-sections of transitional nuclei with large-amplitude shape fluctuations are calculated in a microscopic way by introducing the concept of Instantaneous Shape Sampling. The concept bases on the slow shape dynamics as compared to the fast dipole vibrations. The elctromagnetic dipole strength is calculated by means of RPA for the instantaneous shapes, the probability of which is obtained by means of IBA. Very good agreement with the experimental absorption cross sections near the nucleon emission threshold is obtained.

AdS/CFT with Flavour in Electric and Magnetic Kalb-Ramond Fields

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We investigate gauge/gravity duals with flavour for which pure-gauge Kalb-Ramond B fields are turned on in the background, into which a D7 brane probe is embedded. First we consider the case of a magnetic field in two of the spatial boundary directions. We show that at finite temperature, i.e. in the AdS-Schwarzschild background, the B field has a stabilizing effect on the mesons and chiral symmetry breaking occurs for a sufficiently large value of the B field. Then we turn to the electric case of a B field in the temporal direction and one spatial boundary direction. In this case, there is a singular region in which it is necessary to turn on a gauge field on the brane in order to ensure reality of the brane action. We find that the brane embeddings are attracted towards this region. Far away from this region, in the weak field case at zero temperature, we investigate the meson spectrum and find a mass shift similar to the Stark effect.

Time-Evolving to Space-Evolving Thermal Instability of a Porous Medium Flow

Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: The Rayleigh-Bénard instability of the stationary throughflow in a horizontal porous layer, also known as Prats' problem, is here analysed in a fresh new perspective. In fact, the classical analysis of the linear instability, carried out by employing space-periodic Fourier modes, is here reconsidered by focussing on the effects of time-periodic and space-evolving modes. The basic stationary flow is assumed to be perturbed by a localised source of perturbation which is steady-periodic in time. Then, the streamwise development of such perturbations is monitored in order to detect their possible amplification or decay in the direction of propagation. Accordingly, the spatial stability/instability threshold is determined. The study is carried out by employing a Fourier transform formalism, where the transformed variable is time.

Survival probability of a particle in a sea of mobile traps: A tale of tails

description: We study the long-time tails of the survival probability $P(t)$ of an $A$ particle diffusing in $d$-dimensional media in the presence of a concentration $ρ$ of traps $B$ that move sub-diffusively, such that the mean square displacement of each trap grows as $t^γ$ with $0\leq γ\leq 1$. Starting from a continuous time random walk (CTRW) description of the motion of the particle and of the traps, we derive lower and upper bounds for $P(t)$ and show that for $γ\leq 2/(d+2)$ these bounds coincide asymptotically, thus determining asymptotically exact results. The asymptotic decay law in this regime is exactly that obtained for immobile traps. This means that for sufficiently subdiffusive traps, the moving $A$ particle sees the traps as essentially immobile, and Lifshitz or trapping tails remain unchanged. For $γ> 2/(d+2)$ and $d\leq 2$ the upper and lower bounds again coincide, leading to a decay law equal to that of a stationary particle. Thus, in this regime the moving traps see the particle as essentially immobile. For $d>2$, however, the upper and lower bounds in this $γ$ regime no longer coincide and the decay law for the survival probability of the $A$ particle remains ambiguous.

description: We point out that the Neyman-Pearson lemma applies to Bayes factors if we consider expected type-1 and type-2 error rates. That is, the Bayes factor is the test statistic that maximises the expected power for a fixed expected type-1 error rate. For Bayes factors involving a simple null hypothesis, the expected type-1 error rate is just the completely frequentist type-1 error rate. Lastly we remark on connections between the Karlin-Rubin theorem and uniformly most powerful tests, and Bayes factors. This provides frequentist motivations for computing the Bayes factor and could help reconcile Bayesians and frequentists.

Rapidity divergences and valid definitions of parton densities
Creators: name: Collins, John
Publisher: name: arXiv
Year: 2008
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Rapidity divergences occur when parton densities in a gauge theory are defined in the most natural way, as expectation values of partonic number operators in light-front quantization. I review these and other related divergences, and show how the definitions of parton densities can be modified to remove the divergences. A modified definition is not only essential for many phenomenological applications of QCD, but also concerns the treatment of parton densities in non-perturbative approaches. The necessity of modifications in the definition of a parton density also entails corrections in the formulation of light-front quantization for gauge theories.

TN5 insertions in ribosomal protein genes in Escherichia coli
Creators: name: Hui, Ivy Yuk Chee
Publisher: name: University of British Columbia
Year: 2010

description: The genetic organization and interrelationship between the two ribosomal protein transcription units (the L11 and the L10 operons) from near 89 min on the Escherichia coli chromosome were studied using insertional mutations generated by the kanamycin resistant transposable element Tn5. The polar effects of Tn5 insertion on the expression of these ribosomal genes were examined by: (1) The level of β-galactosidase generated from L10-lacZ and β-lacZ fusion proteins; (2) Direct SDS-polyacrylamide gel electrophoresis of the proteins specified -by the plasmid ribosomal genes in UV-inactivated maxicells; (3) Urea-polyacrylamide gel electrophoresis of plasmid and chromosome specified L12 proteins in an L12 electrophoretic mutant (Strain JF1039). The above experiments localized the major promoter for the L10 operon between nucleotide 1280 and 1360. These investigations also confirmed that the translational regulatory proteins for the L11 and L10 operons are L1 and L10 respectively.
