description: We present a combined photometric and spectroscopic analysis of the star formation history and space density of a sample of 485 luminous, M_V - 5 log h < -20.5, field early-type galaxies at redshifts 0.3 < z < 0.6. The observed b_Jori colours as a function of redshift, mean absorption line strengths and [OII] 3727 emission properties are used to constrain the star formation history of the galaxies. The mean star formation history of the early-type galaxy sample is consistent with an old (z_f>1), passively evolving luminosity-weighted stellar population. Twenty-one percent of the sample possess detectable [OII] 3727 emission consistent with a low level (<1 M_solar/yr) of on-going star formation. Parametric and non-parametric estimates of the space density of the sample are derived. The integrated luminosity density at z ~ 0.4, allowing only for passive luminosity evolution, is in excellent agreement with the local, ( = 0.1), luminosity density of early-type galaxies. Overall, the sample properties are consistent with a galaxy formation scenario in which the majority of luminous field early-type galaxies formed at redshifts z>1 and have largely evolved passively since the formation epoch.

description: We investigate the distribution of roots of polynomials of high degree with random coefficients which, among others, appear naturally in the context of "quantum chaotic dynamics". It is shown that under quite general conditions their roots tend to concentrate near the unit circle in the complex plane. In order to further increase this tendency, we study in detail the particular case of self-inversive random polynomials and show that for them a finite portion of all roots lies exactly on the unit circle. Correlation functions of these roots are also computed analytically, and compared to the correlations of eigenvalues of random matrices. The problem of ergodicity of chaotic wave-functions is also considered. For that purpose we introduce a family of random polynomials whose roots spread uniformly over phase space. While these results are consistent with random matrix theory predictions, they provide a new and different insight into the problem of quantum ergodicity. Special attention is devoted all over the paper to the role of symmetries in the distribution of roots of random polynomials.

description: We compute radiative corrections to nuclear reaction rates that determine the outcome of the Big-Bang Nucleosynthesis (BBN). Any nuclear reaction producing a photon with an energy above $2m_e$ must be supplemented by the corresponding reaction where the final state photon is replaced by an electron-positron pair. We find that pair production brings a typical $0.2 \%$ enhancement to photon emission rates, resulting in a similar size corrections to elemental abundances. The exception is $^4{\rm He}$ abundance, which is insensitive to the small changes in the nuclear reaction rates. We also investigate the effect of vacuum polarisation on the Coulomb barrier, which brings a small extra correction when reaction rates are extrapolated from the measured energies to the BBN Gamow peak energies.

description: The development of information technology has changed people's learning methods. Fragmented learning, as an informal learning method, has become an important way to accept new knowledge and learn new technologies. Through analyzing the connotation, characteristics, and advantages and disadvantages of fragmented learning, this paper came up with reasonable recommendations for fragmented learning. To truly become systematic and holistic knowledge, fragmented knowledge must be explored, understood, integrated and internalized. This paper is expected to play an important guiding role in building a lifelong learning society.

description: The semileptonic decays and two-body nonleptonic decays of light baryon octet ($T_8$) and decuplet ($T_{10}$) consisting of light $u,d,s$ quarks are studied with the SU(3) flavor symmetry in this work. We obtain the amplitude relations between different decay modes by the SU(3) irreducible representation approach, and then predict relevant branching ratios by present experimental data within $1 σ$ error. We find that the predictions for all branching ratios except $\mathcal{B}(Ξ\rightarrow Λ^0π)$ and $\mathcal{B}(Ξ^*\rightarrow Ξπ)$ are in good agreement with present experimental data, that implies the neglected $C_+$ terms or SU(3) breaking effects might contribute at the order of a few percent in $Ξ\rightarrow Λ^0π$ and $Ξ^*\rightarrow Ξπ$ weak decays. We predict that $\mathcal{B}(Ξ^{-}\rightarrow Σ^0μ^-\barν_μ)=(1.13\pm0.08)\times10^{-6}$, $\mathcal{B}(Ξ^{-}\rightarrowΛ^0μ^-\barν_μ)=(1.58\pm0.04)\times10^{-4}$, $\mathcal{B}(Ω^-\rightarrowΞ^0μ^-\barν_μ)=(3.7\pm1.8)\times10^{-3}$, $\mathcal{B}(Σ^-\rightarrow Σ^0e^-\barν_e)=(1.35\pm0.28)\times10^{-10}$, $\mathcal{B}(Ξ^-\rightarrow Ξ^0e^-\barν_e)=(4.2\pm2.4)\times10^{-10}$. We also study $T_{10}\to T_8 P_8$ weak, electromagnetic or strong decays. Some of these decay modes could be observed by the BESIII, LHCb and other experiments in the near future. Due to the very small life times of $Σ^0$, $Ξ^{*0,-}$, $Σ^{*0,-}$ and $Δ^{0,-}$, the branching ratios of these baryon weak decays are only at the order of $\mathcal{O}(10^{-20}-10^{-13}$), which are too small to be reached by current experiments. Furthermore, the longitudinal branching ratios of $T_{8A} \to T_{8B} \ell^- \barν_\ell~(\ell=μ,e)$ decays are also given.

description: We consider the Cauchy problem for the massive Dirac equation in the non-extreme Kerr-Newman geometry outside the event horizon. We derive an integral representation for the Dirac propagator involving the solutions of the ODEs which arise in Chandrasekhar's separation of variables. It is proved that for initial data in L^\infty_loc near the event horizon with L^2 decay at infinity, the probability of the Dirac particle to be in any compact region of space tends to zero as t goes to infinity. This means that the Dirac particle must either disappear in the black hole or escape to infinity.

description: We show that certain dense and spectral invariant subalgebras of a $C^*$-algebra have the same bilateral Bass stable rank. This is a partial answer for (a version of) an open problem raised by R.G. Swan. Then, for certain Banach algebras, we indicate when the homotopy groups $π_{i}(GL_{n}(A))$ stabilize for large $n$. This is an improvement of a result due to G. Corach and A. Larotonda. Using some results due to M. Karoubi, we show the isomorphism of the Witt group of a symmetric Banach algebra with the $K_0$-group of its enveloping $C^*$-algebra. The question if this is true for all involutive Banach algebras was raised by A. Connes.

Especially, an optimal system of one dimensional subalgebras is constructed and some invariant solutions corresponding to the resulted symmetries are obtained.
STRESS AND GAS HYDRATE-FILLED FRACTURE DISTRIBUTION, KRISHNA-GODAVARI BASIN, INDIA
Creators: name: Cook, Ann

Publisher: name: The University of British Columbia
Year: 2008

description: In this research, we study high resistivity fractures found in unconsolidated clay sediments on logging-while-drilling borehole resistivity images from Indian continental margin collected during the National Gas Hydrate Program Expedition 01. These fractures, found at Sites 5, 6, 7, and 10 are likely filled with natural gas hydrate. Gas hydrate is identified on borehole logs and images as high resistivity responses without associated density increases or indications of free gas. The local state of stress at the time of fracturing can be determined by fracture orientations. In Holes 5A, 5B, 6A an 7A the gas hydrate-filled fractures have an aligned, preferred orientation likely associated with a local stress regime. At Site 10, where 130 m of gas hydrate-filled fractures were observed, fracturing is chaotic, likely due to high gas flux.

description: A spider is an axiomatization of the representation theory of a group, quantum group, Lie algebra, or other group or group-like object. We define certain combinatorial spiders by generators and relations that are isomorphic to the representation theories of the three rank two simple Lie algebras, namely A2, B2, and G2. They generalize the widely-used Temperley-Lieb spider for A1. Among other things, they yield bases for invariant spaces which are probably related to Lusztig's canonical bases, and they are useful for computing quantities such as generalized 6j-symbols and quantum link invariants.

description: We study the critical behavior (CB) of all period $p$-tuplings $(p \!=\!2,3,4,\dots)$ in $N$ $(N \!=\! 2,3,4,\dots)$ symmetrically coupled one-dimensional maps. We first investigate the CB for the $N=2$ case of two coupled maps, using a renormalization method. Three (five) kinds of fixed points of the renormalization transformation and their relevant ``coupling eigenvalues'' associated with coupling perturbations are found in the case of even (odd) $p$. We next study the CB for the linear- and nonlinear-coupling cases (a coupling is called linear or nonlinear according to its leading term), and confirm the renormalization results. Both the structure of the critical set (set of the critical points) and the CB vary according as the coupling is linear or nonlinear. Finally, the results of the two coupled maps are extended to many coupled maps with $N \geq 3$, in which the CB depends on the range of coupling.

description: We have obtained high quality FORS1/VLT optical spectra of 85 disk HII regions several nearby spiral galaxies. Our sample of metal-rich HII regions with metallicities close to solar and higher reveal the presence of Wolf-Rayet (WR) stars in 27 objects from the blue WR bump and 15 additional candidate WR regions. This provides for the first time a large set of metal-rich WR regions. Approximately half of the WR regions also show broad CIV emission attributed to WR stars of the WC subtype (...). The WR regions show quite clear trends between their observed WR features and the Hbeta emission line. Detailed synthesis models are presented to understand/interpret these observations. (...) The availability of a fairly large sample of metal-rich WR regions allows us to improve existing estimates of the upper mass cut-off of the IMF in a robust way and independently of detailed modeling: from the observed maximum Hbeta equivalent width of the WR regions we derive a LOWER LIMIT for M_up of 60-90 Msun in the case of a Salpeter slope and larger values for steeper IMF slopes. From our direct probe of the massive star content we conclude that there is at present no evidence for systematic variations of the upper mass cut-off of the IMF in metal-rich environments, in contrast to some claims based on indirect nebular diagnostics.

description: The miniaturisation of chemical and biological systems has become a research focus since the last century. Compared to conventional bulk reactors, microreactors have numerous advantages such as larger surface-area-to-volume ratio, higher heat and mass transfer rates as well as the reduction in energy demand and waste generation. Miniaturisation also improves control over reaction parameters and enhances reaction safety especially if hazardous substances are involved. The need for miniaturised reaction systems has led to the development of various microreactor platforms such as droplet-based microreactors. However, these platforms possess inherent drawbacks such as rapid evaporation and difficulty in handling a minute amount of liquid that have limited their implementation in practical applications. Liquid marbles are droplets covered with hydrophobic particles and present a platform that can potentially overcome the weaknesses of bare droplets. The coating layers completely isolate the interior liquids from the surrounding environment, thus conveniently encapsulating the reactions. Great efforts have been made over the past decade to demonstrate the feasibility of liquid marble-based microreactors for chemical and biological applications. Nevertheless, the inability to monitor reactions and the lack of an effective mixing method remains the main obstacles that can significantly hinder the potential of liquid marble-based microreactors. In order to benefit from the full potential of liquid marbles as universal microreactors, it is necessary to develop effective methods to enhance the mixing and monitoring abilities in liquid marbles. My Ph.D research focuses on developing methods to enhance the ability to monitor reaction and to improve mixing process in liquid marble-based platform.

description: Malware attacks are a significant part of the new software security threats detected each year. Intel Software Guard Extensions (SGX) are a set of hardware instructions introduced by Intel in their recent lines of processors that are intended to provide a secure execution environment for user-developed applications. To our knowledge, there was no serious attempt yet to overcome the SGX protection by exploiting the weaknesses in the software supply chain infrastructure, namely at the level of the development, build or signing servers. While SGX protection does not specifically take into consideration such threats, we show in the current paper that a simple malware attack exploiting a separation between the build and signing processes can have a serious damaging impact, practically nullifying SGX integrity protection measures. We also explore two possible mitigations against the attack, one centralized leveraging SGX itself, and one distributed that relies on a smart contract deployed on a blockchain infrastructure. Our evaluation shows that both methods are feasible in practice and their added costs are acceptable for the offered protection.

description: The logarithmic negativity of a bipartite quantum state is a widely employed entanglement measure in quantum information theory, due to the fact that it is easy to compute and serves as an upper bound on distillable entanglement. More recently, the $κ$-entanglement of a bipartite state was shown to be the first entanglement measure that is both easily computable and has a precise information-theoretic meaning, being equal to the exact entanglement cost of a bipartite quantum state when the free operations are those that completely preserve the positivity of the partial transpose [Wang and Wilde, Phys. Rev. Lett. 125(4):040502, July 2020]. In this paper, we provide a non-trivial link between these two entanglement measures, by showing that they are the extremes of an ordered family of $α$-logarithmic negativity entanglement measures, each of which is identified by a parameter $α\in[ 1,\infty] $. In this family, the original logarithmic negativity is recovered as the smallest with $α=1$, and the $κ$-entanglement is recovered as the largest with $α=\infty$. We prove that the $α$-logarithmic negativity satisfies the following properties: entanglement monotone, normalization, faithfulness, and subadditivity. We also prove that it is neither convex nor monogamous. Finally, we define the $α$-logarithmic negativity of a quantum channel as a generalization of the notion for quantum states, and we show how to generalize many of the concepts to arbitrary resource theories.

description: We investigate the dark matter profile of the Milky Way using the observed rotation curve data out to 100 kpc. The baryonic matter of the Milky Way is divided into bulge, disk and gas components, and each component is modelled using various possible mass profiles available in literature. The arbitrary combination of seven bulge profiles, four disk profiles and two gas profiles results in fifty-six baryon models. These baryon models are combined with one of the four dark matter profiles: Burkert profile, core-modified profile, pseudo-isothermal profile and NFW profile, to fit the observed rotation curve data. Results show that in general the NFW profile fits the data better than the Burkert profile, while the core-modified profile and the pseudo-isothermal profile are essentially ruled out. The best-fitting NFW model has the scale length $r_0=8.1\pm 0.7$ kpc, and the corresponding local density of dark matter is $ρ_{\rm dm}(R=R_\odot)=0.51\pm0.09~{\rm GeV}/{\rm cm}^3$.

description: This dissertation studies the impact of institutional interventions on labor markets in the United States, Norway and India. The labor markets studied are diverse, and include the criminal sector in the United States, the healthcare sector in Norway and the market for workfare employment in rural India.
      Chapter 1 studies whether juvenile offenders are deterred by the threat of criminal sanctions. Existing research, which studies adolescent crime as a series of on-the-spot decisions, finds that deterrence estimates are negligible at best. This paper first presents a model that allows the return from crime to increase with previous criminal involvement. The predictions of the model are tested using policy variation in the United States over the period 2006-15. The results show that when criminal capital accumulates, juveniles may respond in anticipation of increases in criminal sanctions. Accounting for these anticipatory responses can overturn the conclusion that harsh sanctions do not deter juvenile crime.
      Chapter 2 studies the impact of a graduate's first job on her career trajectory, and how job-seeking graduates’ respond to the persistence of these "first job effects". For identification, we exploit a natural experiment in Norway, where doctors' first jobs were allocated through a random serial dictatorship mechanism until 2013. We use administrative data on individual outcomes to confirm empirically that the residency allocation mechanism effectively randomized choice sets of hospitals across medical graduates. We then use the resulting variation in individual doctors’ choice sets to show that first jobs affect doctors' earnings, place of residence, and specialization in the long run.
      Chapter 3 evaluates the effects of encouraging the selection of local politicians in India via community-based consensus, as opposed to a secret ballot election. I find that financial incentives aimed at encouraging consensus-based elections and discouraging political competition crowd in younger, more educated political representatives. However, these incentives also lead to worse governance as measured by a fall in local expenditure and regressive targeting of workfare employment. These results can be explained by the fact that community-based processes are prone to capture by the local elite, and need not improve the quality of elected politicians or governance.

description: A molecular porous material, MPM-2, comprised of cationic [Ni2(AlF6) (pzH)8(H2O)2] and anionic [Ni2Al2F11(pzH)8(H2O)2] complexes that generate a charge-assisted hydrogen-bonded network with pcu topology is reported. The packing in MPM-2 is sustained by multiple interionic hydrogen bonding interactions that afford ultramicroporous channels between dense layers of anionic units. MPM-2 is found to exhibit excellent stability in water (>1 year). Unlike most hydrogen-bonded organic frameworks which typically show poor  stability in organic solvents, MPM-2 exhibited excellent stability with respect to various organic solvents for at least two days. MPM-2 is found to be permanently porous with gas sorption isotherms at 298 K revealing a strong affinity for C2H2 over CO2 thanks to a high (ΔQst)AC [Qst (C2H2) − Qst (CO2)] of 13.7 kJ mol−1 at low coverage. Dynamic column breakthrough experiments on MPM-2 demonstrated the separation of C2H2 from a 1:1 C2H2/CO2 mixture at 298 K with effluent CO2 purity of 99.995% and C2H2 purity of >95% after temperature-programmed desorption. C-H···F interactions between C2H2 molecules and F atoms of AlF6 3− are found to enable high selectivity toward C2H2, as determined by density functional theory simulations.

description: Frictional forces affect the rheology of hard-sphere colloids, at high shear rate. Here we demonstrate, via numerical simulations, that they also affect the dynamics of active Brownian particles, and their motility induced phase separation. Frictional forces increase the angular diffusivity of the particles, in the dilute phase, and prevent colliding particles from resolving their collision by sliding one past to the other. This leads to qualitatively changes of motility-induced phase diagram in the volume-fraction motility plane. While frictionless systems become unstable towards phase separation as the motility increases only if their volume fraction overcomes a threshold, frictional system become unstable regardless of their volume fraction. These results suggest the possibility of controlling the motility induced phase diagram by tuning the roughness of the particles.

description: The growing complexity and diversity of models used in the engineering of dependable systems implies that a variety of formal methods, across differing abstractions, paradigms, and presentations, must be integrated. Such an integration relies on unified semantic foundations for the various notations, and co-ordination of a variety of automated verification tools. The contribution of this paper is Isabelle/UTP, an implementation of Hoare and He's Unifying Theories of Programming, a framework for unification of formal semantics. Isabelle/UTP permits the mechanisation of computational theories for diverse paradigms, and their use in constructing formalised semantic models. These can be further applied in the development of verification tools, harnessing Isabelle's proof automation facilities. Several layers of mathematical foundations are developed, including lenses to model variables and state spaces as algebraic objects, alphabetised predicates and relations to model programs, including algebraic and axiomatic semantics, proof tools for Hoare logic and refinement calculus, and UTP theories to encode computational paradigms.

HYDRATE INHIBITION VIA COLD FLOW - NO CHEMICALS OR INSULATION
Creators: name: Turner, Doug

Publisher: name: The University of British Columbia
Year: 2008

description: Nonadhesive hydrate slurries have been shown to exhibit low viscosities in a field-scale flow loop when formed under appropriate conditions. The factors that favor formation of low-viscosity hydrate slurries include high Reynolds Number and Capillary Number, and high mass transfer and heat transfer rates. High liquid loading and high superficial fluid velocities are found to be conducive to the formation of low viscosity hydrate slurries. Dispersed bubble flow has been observed to facilitate flowable hydrate slurry production. Alternatively, the formation of nonadhesive hydrates at moderate superficial velocity is possible when a static mixer is used upstream of the hydrate formation location. For certain fields, low-viscosity hydrate slurry technology could eliminate the need for insulation and hydrate inhibitor chemicals (revised version of ICGH 2008 paper 5818) .

description: Purpose: The purpose of this study was to investigate the effectiveness of a self-administered naming treatment for one individual, B.N., presenting with semantic variant primary progressive aphasia (svPPA) and a history of traumatic brain injury (TBI).Method: Naming treatment included components of Lexical Retrieval Cascade Treatment and was self-administered using an adaptive spaced retrieval software, Anki. Using a multiple-baseline, single-case experimental design, naming accuracy probes were taken during pretreatment, treatment, posttreatment, and follow-up (through 12 months) for 60 trained words and 10 untrained words. Item-level Bayesian generalized mixed-effects models were used to estimate (a) the treatment effect for trained words, (b) change in untrained words, and (c) maintenance of treatment effects from posttreatment to each subsequent follow-up.Results: Statistical analyses revealed that a gain of 35 out of 60 trained words (35.3; 90% CI [30.6, 39.5]) was directly attributable to treatment. Following treatment, evidence of generalization to untrained words was not observed. During the follow-up period, there was gradual decline in naming accuracy of trained items.Conclusions: The positive treatment results reported here support the use of self-administered naming treatments for those with svPPA and a history of TBI. Although the utility of this treatment approach is constrained by patient factors including motivation, self-administered naming treatments represent a unique opportunity to expand access to speech-language intervention for people with svPPA, including those with concomitant diagnoses.Supplemental Material S1.
