description: The lowest energy configurations of Cn(n =< 55) clusters are obtained using the energy mini- mization technique with the conjugate gradient (CG) method where a modified Brenner potential is invoked to describe the carbon and hydrocarbon interaction. We found that the ground state configuration consists of a single ring for small number of C atoms and multi-ring structures are found with increasing n, which can be in planar, bowl-like or cap-like form. Contrary to previous predictions, the binding energy Eb does not show even-odd oscillations and only small jumps are found in the Eb(n) curve as a consequence of specific types of edges or equivalently the number of secondary atoms. We found that hydrogenation of the edge atoms may change the ground state configuration of the nanocluster. In both cases we determined the magic clusters. Special attention is paid to trigonal and hexagonal shaped carbon clusters and to clusters having a graphene-like configuration. Trigonal clusters are never the ground state, while hexagonal shaped clusters are only the ground state when they have zigzag edges.

Subjects: Probability weighted moments; Rényi and Shannon entropy; Extended generalized exponential distribution; Regular family of distributions‎

description: In this paper, we introduce a univariate four-parameter distribution. Several known distributions like exponentiated Weibull or extended generalized exponential distribution can be obtained as special case of this distribution. The new distribution is quite flexible and can be used quite effectively in analysing survival or reliability data. It can have a decreasing, increasing, decreasing-increasing-decreasing (DID), upside-down bathtub (unimodal) and bathtub-shaped failure rate function depending on its parameters. We provide a comprehensive account of the mathematical properties of the new distribution. In particular, we derive expressions for the moments, mean deviations, Rényi and Shannon entropy. We discuss maximum likelihood estimation of the unknown parameters of the new model for censored and complete sample using the profile and modified likelihood functions. One empirical application of the new model to real data are presented for illustrative purposes.

RESEARCHING THE EXPERIENCES OF SOME COUNTRIES ON ANTI-CORRUPTION EFFORTS AND LESSONS FOR VIETNAM
Creators: name: LE VAN NAM
Publisher: name: Zenodo

Subjects: Corruption, Vietnam, Worldwide.

description: Abstract 
Corruption is a long-standing social issue present in all countries, regardless of their political system or level of development. Corruption involves individuals in positions of power and authority exploiting their positions for personal gain. Common types of corruption include political corruption, administrative corruption, and economic corruption. Economic corruption occurs in economic management activities such as production, business, services, public asset procurement, and asset management, carried out by individuals with authority in state economic management or state-owned enterprises. Manifestations of economic corruption include embezzlement of state or citizens' assets for personal gain, making illegal or biased economic decisions for personal gain, and exploiting legal loopholes or violating laws to engage in production, business, or profiteering at the expense of society. Corruption, especially when perpetrated by those in power, has serious consequences, not only in terms of economic damage and a decline in the quality of governance but also in eroding public trust in the leadership of the Party, State, and the country's international reputation. With the Party and State's close attention and guidance, and the collective effort of the political system, the anti-corruption work in Vietnam has made significant progress in recent years. From 2017 to the present, several legal documents related to anti-corruption have been enacted, such as the Anti-Corruption Law effective from July 1, 2019, and the Whistleblower Protection Law effective from January 1, 2019. In addition, various decrees, decisions, and directives have played a significant role in anti-corruption efforts in Vietnam. Despite positive legal developments, investigations since 2017 have exposed a significant number of large-scale corruption cases, particularly in areas such as banking, management, the use of public investment funds, and state-owned land. In reality, corruption has become increasingly sophisticated and complex, with perpetrators exploiting legal gaps. In recent years, many economic-related scandals have emerged, highlighting the interconnectedness between financial aspects and corruption. Therefore, evaluating anti-corruption efforts from a financial perspective and finding comprehensive solutions are essential. Studying the essence of corruption, its forms, causes, and drawing lessons from other countries' experiences in combating corruption is of utmost importance in formulating effective anti-corruption measures in Vietnam for the future.

Stability analysis of the Martian obliquity during the Noachian era
Creators: name: Brasser, Ramon

Publisher: name: arXiv
Year: 2011
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: We performed numerical simulations of the obliquity evolution of Mars during the Noachian era, at which time the giant planets were on drastically different orbits than today. For the preferred primordial configuration of the planets we find that there are two large zones where the Martian obliquity is stable and oscillates with an amplitude lower than 20$^\circ$. These zones occur at obliquities below 30$^\circ$ and above 60$^\circ$; intermediate values show either resonant or chaotic behaviour depending on the primordial orbits of the terrestrial planets.
Quantile-Based Generalized Entropy of Order (α, β) for Order Statistics

Year: 2019
Subjects: Quantile function; Quantile entropy; Reliability measures; Series and parallel system

description: In the present paper, we propose a quantile version of generalized entropy measure for order statistics for residual and past lifetimes and study their properties. Lower and upper bound of the proposed measures are derived. It is shown that the quantile-based generalized information between i-th order statistics and parent random variable is distribution free. The uniform, exponential, generalized Pareto and finite range distributions, which are commonly used in the reliability modeling have been characterized in terms of the proposed entropy measure with extreme order statistics.

Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: We present two Suzaku observations of the Galactic center microquasar 1E 1740.7-2942 separated by approximately 700 days. The source was observed on both occasions after a transition to the spectrally hard state. Significant emission from 1E 1740.7-2942 is detected out to an energy of 300 keV, with no spectral break or turnover evident in the data. We tentatively measure a lower limit to the cut-off energy of ~ 380 keV. The spectra are found to be consistent with a Comptonized corona on both occasions, where the high energy emission is consistent with a hard power-law (Γ~ 1.8) with a significant contribution from an accretion disc with a temperature of ~ 0.4 keV at soft X-ray energies. The measured value for the inner radius of the accretion disc is found to be inconsistent with the picture whereby the disc is truncated at large radii in the low-hard state and instead favours a radius close to the ISCO (R_in ~ 10 - 20 R_g).

description: Discrete power distributions are proposed and studied, by considering the positive jumps on the discontinuities of an original discrete distribution function. Inequalities in moments and distribution functions are studied, allowing the definition of discrete intermediate distributions that lie between an original distribution and a power distribution. Original uniform, binomial, Poisson, negative binomial, and hypergeometric distributions are considered, to propose new power and intermediate distributions. Stochastic orders and unimodality are discussed. Estimation problems using likelihood are investigated. Simulation experiments are performed, to evaluate the bias and the mean square error of the maximum likelihood estimates, that are numerically calculated, with classic tools for numerical optimization.

description: We generalize and refine the hyperkähler Arnold conjecture, which was originally established, in the non-degenerate case, for three-dimensional time by Hohloch, Noetzel and Salamon by means of hyperkähler Floer theory. In particular, we prove the conjecture in the case where the time manifold is a multidimensional torus and also establish the degenerate version of the conjecture. Our method relies on Morse theory for generating functions and a finite-dimensional reduction along the lines of the Conley-Zehnder proof of the Arnold conjecture for the torus.

Photospheric flux cancellation and associated flux rope formation and eruption

name: Kliem, B.

Publisher: name: arXiv
Year: 2010
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We study an evolving bipolar active region that exhibits flux cancellation at the internal polarity inversion line, the formation of a soft X-ray sigmoid along the inversion line and a coronal mass ejection. The evolution of the photospheric magnetic field is described and used to estimate how much flux is reconnected into the flux rope. About one third of the active region flux cancels at the internal polarity inversion line in the 2.5~days leading up to the eruption. In this period, the coronal structure evolves from a weakly to a highly sheared arcade and then to a sigmoid that crosses the inversion line in the inverse direction. These properties suggest that a flux rope has formed prior to the eruption. The amount of cancellation implies that up to 60% of the active region flux could be in the body of the flux rope. We point out that only part of the cancellation contributes to the flux in the rope if the arcade is only weakly sheared, as in the first part of the evolution. This reduces the estimated flux in the rope to $\sim\!30%$ or less of the active region flux. We suggest that the remaining discrepancy between our estimate and the limiting value of $\sim\!10%$ of the active region flux, obtained previously by the flux rope insertion method, results from the incomplete coherence of the flux rope, due to nonuniform cancellation along the polarity inversion line. A hot linear feature is observed in the active region which rises as part of the eruption and then likely traces out field lines close to the axis of the flux rope. The flux cancellation and changing magnetic connections at one end of this feature suggest that the flux rope reaches coherence by reconnection shortly before and early in the impulsive phase of the associated flare. The sigmoid is destroyed in the eruption but reforms within a few hours after a moderate amount of further cancellation has occurred.

Metal element multiply bonded group 6 complexes with 1,3-N,O-donor ligands
Creators: name: Clarkson, Joseph Mitchell
Publisher: name: University of British Columbia
Year: 2019

description: This thesis discusses the synthesis and characterization of group 6 complexes that have metal element multiple bonds and 1,3-N,O-donor ligands. Furthermore, the evaluation of the metal-ligand interactions, including hemilability and metal-ligand cooperativity in E-H bond activation processes (where E=C or N), of the 1,3-N,O-donor ligands that resulted in reactivity of the metal element multiple bonds is reported. The 1,3-N,O-donor ligands in this thesis include amidates and pyridonates. The 1,3-N,O-donor ligands were installed on group 6 metals directly from the 1,3-N,O-proligands or as deprotonated sodium salts of the 1,3-N,O-proligands, by protonolysis or salt metathesis reactions respectively. Complexes such as di(1,3-N,O-chelate)bis(t-butylimido)tungsten and di(1,3-N,O-chelate)bis(dimethylamido)molybdenum, were synthesized by protonolysis reactions in chapters 2 and 4 respectively. In chapter 3 di(1,3-N,O-ligated)(neopentylidene)(oxo)tungsten complexes were synthesized by both protonolysis and salt metathesis reactions. These group 6 complexes with 1,3-N,O-donor ligands were characterized by single crystal X-ray diffraction, and in solution by multinuclear NMR spectroscopies, among other analytical methods. The solid-state molecular structures showed κ²-N,O, κ¹-O and µ²-N,O bonding modes, highlighting the flexibility of the 1,3-N,O-donor ligands. Solution NMR spectroscopy showed fluxional 1,3-N,O-donor ligands in all complexes at elevated temperatures, further highlighting the hemilability of these ligands. Throughout this thesis, pyridonate ligands showed more dynamic hemilability relative to amidate ligands. In chapter 2 pyridonate ligands were observed to have κ²-N,O, κ¹-O and µ²-N,O bonding modes in the solid state, whereas amidate ligands where exclusively bound in a κ²-N,O in the solid state. Variable temperature ¹H-NMR spectroscopy demonstrated that pyridonate ligands were fluxional at temperatures above -40 °C, whereas amidate ligands were fluxional at elevated temperatures (>60 °C). The steric parameters of 1,3-N,O-donor ligands influence how the ligands prefer to bond to the metal. Furthermore the steric demand also influences the hemilability of the 1,3-N,O-donor ligands. The differences in the electronic parameters between amidate and pyridonate ligands influences their hemilability, where pyridonates exhibit more dynamic hemilability in part due to the aryloxy imine motif. The metal-ligand cooperativity of the hemilabile 1,3-N,O-donor ligands towards E-H bond activations (where E=C or N) is reported in this thesis and applications of these processes are discussed.

description: In the present work we have proposed the method that allows one to easily estimate hardness and bulk modulus of known or hypothetical solid phases from the data on Gibbs energy of atomization of the elements and corresponding covalent radii. It has been shown that hardness and bulk moduli of compounds strongly correlate with their thermodynamic and structural properties. The proposed method may be used for a large number of compounds with various types of chemical bonding and structures; moreover, the temperature dependence of hardness may be calculated, that has been performed for diamond and cubic boron nitride. The correctness of this approach has been shown for the recently synthesized superhard diamond-like BC5. It has been predicted that the hypothetical forms of B2O3, diamond-like boron, BCx and COx, which could be synthesized at high pressures and temperatures, should have extreme hardness.

description: We show anisotropy of the dipole interaction between magnetic atoms or polar molecules can stabilize new quantum phases in an optical lattice. Using a well controlled numerical method based on the tensor network algorithm, we calculate phase diagram of the resultant effective Hamiltonian in a two-dimensional square lattice - an anisotropic Hubbard model of hard-core bosons with attractive interaction in one direction and repulsive interaction in the other direction. Besides the conventional superfluid and the Mott insulator states, we find the striped and the checkerboard charge density wave states and the supersolid phase that interconnect the superfluid and the striped solid states. The transition to the supersolid phase has a mechanism different from the case of the soft-core Bose Hubbard model.

description: We correct claims about lower bounds on mutual information (MI) between real-valued random variables made in A. Kraskov {\it et al.}, Phys. Rev. E {\bf 69}, 066138 (2004). We show that non-trivial lower bounds on MI in terms of linear correlations depend on the marginal (single variable) distributions. This is so in spite of the invariance of MI under reparametrizations, because linear correlations are not invariant under them. The simplest bounds are obtained for Gaussians, but the most interesting ones for practical purposes are obtained for uniform marginal distributions. The latter can be enforced in general by using the ranks of the individual variables instead of their actual values, in which case one obtains bounds on MI in terms of Spearman correlation coefficients. We show with gene expression data that these bounds are in general non-trivial, and the degree of their (non-)saturation yields valuable insight.

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: Ultraviolet observations of classical T Tauri Stars (cTTSs) have shown that there is a hot (Te ~ 80,000 K) and dense (ne ~ 1e10 cm-3) component associated with the large scale jet. This hot component is formed very close to the base of the jet providing fundamental information on the jet formation mechanism. In this series, we have investigated whether this component can be formed in disc winds, either cool or warm. To conclude the series, jet launching from the interface between the magnetic rotor (the star) and the disc is studied. Synthetic profiles are calculated from numerical simulations of outflow launching by star-disc interaction. Profiles are calculated for several possible configurations of the stellar field: dipolar (with surface strengths, B of 1, 2 and 5 kG) or dynamo fed. Also two types of discs, passive or subjected to an alpha/Omega-dynamo, are considered. These profiles have been used to define the locus of the various models in the observational diagram: dispersion versus centroid, for the profiles of the SiIII] line. Bulk motions produce an increasing broadening of the profile as the lever arm launching the jet becomes more efficient; predicted profiles are however, sensitive to the disc inclination. Models are compared with observations of the SiIII] lines obtained with the Hubble Space Telescope. In addition, it is shown that the non-stationary nature of star-disc winds produce a flickering of the profile during quiescence with variations in the line flux of about 10%. At outburst, accretion signatures appear in the profiles together with an enhancement of the wind, producing the correlation between accretion and outflow as reported from RU Lup, AA Tau and RW Aur observations.

description: We calculate a nonequilibrium steady state of a quantum XX chain in the presence of dephasing and driving due to baths at chain ends. The obtained state is exact in the limit of weak driving while the expressions for one- and two-point correlations are exact for an arbitrary driving strength. In the steady state the magnetization profile and the spin current display diffusive behavior. Spin-spin correlation function on the other hand has long-range correlations which though decay to zero in either the thermodynamical limit or for equilibrium driving. At zero dephasing a nonequilibrium phase transition occurs from a ballistic transport having short-range correlations to a diffusive transport with long-range correlations.

description: Spin-related electronic phase transitions in the fractional quantum Hall regime are accompanied by a large change in resistance. Combined with their sensitivity to spin orientation of nuclei residing in the same plane as the 2D electrons, they offer a convenient electrical probe to carry out nuclear magnetometry. Despite conditions which should allow both electronic and nuclear-spin subsystems to approach thermodynamic equilibrium, we uncover for the nuclei a remarkable and strongly electronic filling-factor-dependent deviation from the anticipated thermal nuclear-spin polarization.

description: In eukaryotic cell nuclei, a variety of DNA interactions with nuclear elements occur, which, in combination with intra- and inter- chromosomal cross-talks, shape a functional 3D architecture. In some cases they are organized by active, i.e. actin/myosin, motors. More often, however, they have been related to passive diffusion mechanisms. Yet, the crucial questions on how DNA loci recognize their target and are reliably shuttled to their destination by Brownian diffusion are still open. Here, we complement the current experimental scenario by considering a physics model, in which the interaction between distant loci is mediated by diffusing bridging molecules. We show that, in such a system, the mechanism underlying target recognition and colocalization is a thermodynamic switch-like process (a phase transition) that only occurs if the concentration and affinity of binding molecules is above a threshold, or else stable contacts are not possible. We also briefly discuss the kinetics of this "passive-shuttling" process, as produced by random diffusion of DNA loci and their binders, and derive predictions based on the effects of genomic modifications and deletions.
Evaluation of in-situ laser ultrasonics for abnormal grain growth in a plain carbon steel
Creators: name: Tran, Brian
Publisher: name: University of British Columbia
Year: 2018

description: The control of grain size distribution is an important factor governing the homogeneity of mechanical properties for steels and other alloys used in a wide range of applications. In the present work, the evolution of austenite grain size is in-situ monitored in an A36 plain carbon steel during isothermal holding between 900°C and 1150°C using laser ultrasonics. In this technique, the attenuation of laser generated ultrasound is related to a representative mean grain size in the material. In A36 steel, the coarsening and dissolution of AlN precipitates at 1000°C leads to a stage of abnormal austenite grain growth with the development of a bimodal grain size distribution. This stage corresponds to a period of high grain growth rate when measured by laser ultrasonics, suggesting that the technique is sensitive to the progression of abnormal grain growth stages. For abnormal grain growth scenarios, the laser ultrasonic measurements are compared with ex-situ metallographic measurements of large grain area fraction on quenched samples. Experimental correlation between laser ultrasonic grain size measurement and area fraction of large grains is validated with a finite element analysis of ultrasound wave propagation in an anisotropic polycrystalline aggregate of controlled grain size distribution. The numerical analysis provides important insight into the scattering of ultrasound waves in a material of heterogeneous grain size. The range of applicability for the laser ultrasonic technique is evaluated using grain size calculations from simulated attenuation for selected grain size distributions.

description: We present some advances, both from a theoretical and from a computational point of view, on a quadratic vector equation (QVE) arising in Markovian Binary Trees. Concerning the theoretical advances, some irreducibility assumptions are relaxed, and the minimality of the solution of the QVE is expressed in terms of properties of the Jacobian of a suitable function. From the computational point of view, we elaborate on the Perron vector-based iteration proposed in [http://arxiv.org/abs/1006.0577]. In particular we provide a condition which ensures that the Perron iteration converges to the sought solution of the QVE. Moreover we introduce a variant of the algorithm which consists in applying the Newton method instead of a fixed-point iteration. This method has the same convergence behaviour as the Perron iteration, since its convergence speed increases for close-to-critical problems. Moreover, unlike the Perron iteration, the method has a quadratic convergence. Finally, we show that it is possible to alter the bilinear form defining the QVE in several ways without changing the solution. This modification has an impact on convergence speed of the algorithms.

description: A set S of n points is 2-color universal for a graph G on n vertices if for every proper 2-coloring of G and for every 2-coloring of S with the same sizes of color classes as G has, G is straight-line embeddable on S. We show that the so-called double chain is 2-color universal for paths if each of the two chains contains at least one fifth of all the points, but not if one of the chains is more than approximately 28 times longer than the other. A 2-coloring of G is equitable if the sizes of the color classes differ by at most 1. A bipartite graph is equitable if it admits an equitable proper coloring. We study the case when S is the double-chain with chain sizes differing by at most 1 and G is an equitable bipartite graph. We prove that this S is not 2-color universal if G is not a forest of caterpillars and that it is 2-color universal for equitable caterpillars with at most one half non-leaf vertices. We also show that if this S is equitably 2-colored, then equitably properly 2-colored forests of stars can be embedded on it.

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We present the results of a 40 ks Chandra observation of the quiescent stellar mass black hole GS 1354-64. A total of 266 net counts are detected at the position of this system. The resulting spectrum is found to be consistent with the spectra of previously observed quiescent black holes, i.e., a power-law with a photon index of Γ~ 2. The inferred luminosity in the 0.5 -- 10 keV band is found to lie in the range 0.5 - 6.5 x 10^{34} erg/s, where the uncertainty in the distance is the dominant source of this large luminosity range. Nonetheless, this luminosity is over an order of magnitude greater than that expected from the known distribution of quiescent stellar mass black hole luminosities and makes GS 1354-64 the only known stellar mass black hole to disagree with this relation. This observation suggests the possibility of significant accretion persisting in the quiescent state.

Antimicrobial resistance in a membrane enhanced biological phosphorus removal process

Publisher: name: University of British Columbia

description: Coupling of membrane bioreactors with enhanced biological phosphorus removal (EBPR) processes increases the potential for low-yield sludge production by operating systems at long solids retention times (SRTs). However, biological foaming of anoxic mixed liquor in membrane EBPR (MEBPR) systems causes operational challenges (e.g. interference with the estimation of total suspended solids in the system). Hence, operating MEBPR systems by regular wastage of foam bacteria as a means to control SRT has gained increasing attention. The present research aims to evaluate the performance of MEBPR processes operating at long SRT (60 days) through estimation of the ARB release rates in foam, waste aerobic mixed liquor and effluent. The results indicated that, while superior antibiotic resistant bacterial (ARB) removal was achieved by membrane filtration in MEBPR systems (SRT= 60 and 25 days (control)), the proportions of sulfamethoxazole and trimethoprim resistant bacteria among mixed liquor heterotrophs exhibited statistically significant elevations relative to the influent. It was also demonstrated that extended SRT operations could achieve similar total daily release rates of ARB (amoxicillin, sulfamethoxazole, tetracycline) compared to those of the 25 day SRT train. In detail, waste aerobic mixed liquor and foam were found to be the major contributors to ARB release in the 25 and 60 day SRT trains, respectively. Data also showed that operating MEBPR systems at 25 and 60 day SRTs could reduce the total ARB release rates relative to the ARB inflow rates. It was also observed that the parallel trains significantly increased the relative abundances of the sul1 gene (normalized to 16S rRNA gene) in mixed liquor compared to those of the influent. Using an Illumina MiSeq platform, the taxonomic compositions of bacterial communities in influent and MEBPR environments were identified. Data analysis exhibited a shift in bacterial composition from influent to mixed liquor and then to treated effluent. A significant similarity was also found between mixed liquor and foam at the 25 day SRT train. Finally, PCR-based examination and functional screening of the fosmid library revealed the presence of nine antibiotic resistance genes conferring resistance to four classes of antimicrobials in the foaming compartment of the MEBPR process.
