The functionalization of methane and other hydrocarbons mediated by organometallic nitrosyl complexes of tungsten
Creators: name: Baillie, Rhett A.
Publisher: name: University of British Columbia
Year: 2016

description: The novel family of Cp*W(NO)(H)(η³-allyl) complexes has been synthesized and characterized. Upon thermolysis these compounds generate 16e Cp*W(NO)(η²-alkene) intermediate complexes that have been trapped as their corresponding 18e PMe₃ adducts. In neat alkane solutions, these Cp*W(NO)(η²-alkene) compounds effect three successive C-H activations of the alkane to produce a new Cp*W(NO)(H)(η³-allyl) complex in which the allyl ligand is derived from the alkane solvent. In the presence of CO, the Cp*W(NO)(H)(η³-allyl) complexes effect the regiospecific generation of saturated unsymmetrical ketones from hydrocarbons and CO gas via C-H activation and the formation of two new C-C bonds. For instance, the complex Cp*W(NO)(H)(η³-CH₂CHCMe₂) effects the conversion of benzene and mesitylene into the ketones 4-methyl-1-phenylpentan-1-one and 1-(3,5-dimethylphenyl)-5-methylhexan-2-one, respectively. The organometallic product of these reactions is Cp*W(NO)(CO)₂ which can be converted into the Cp*W(NO)(H)(η³-allyl) reactant in three steps, thereby completing a complete cycle with respect to tungsten. The conversion of methane into the β,γ-unsaturated ketone, 5-methylhex-4-en-2-one, is initiated by the complex Cp*W(NO)(CH₂CMe₃)(η³-CH₂CHCMe₂). In a cyclohexane solution, the complex effects the C-H activation of methane to produce Cp*W(NO)(CH₃)(η³-CH₂CHCMe₂) which has been fully characterized. Under CO pressure, the methyl ligand is converted into an acyl ligand in Cp*W(NO)(C(=O)CH₃)(η³-CH₂CHCMe₂), and then the acyl and allyl ligands couple to give Cp*W(NO)(CO)(η²-CH₂=CHCMe₂C(=O)CH₃) which contains an η²-bound ketone ligand. Finally, the ketone is released at 170 °C under CO pressure and Cp*W(NO)(CO)₂ is obtained which again can be converted back into the starting organometallic compound. Each of these organometallic complexes has been isolated and fully characterized, thereby allowing the stepwise transformation of methane through C-H activation and C-C bond-forming reactions to be definitively established. In a similar fashion, the complex Cp*W(NO)(CH₂CMe₃)(η³-CH₂CHCHPh) converts methane and ethane to the corresponding η²-bound ketone complexes, Cp*W(NO)(CO)(η²-PhCH=CHCH₂C(=O)CH₃) and Cp*W(NO)(CO)(η²-PhCH=CHCH₂C(=O)Et). The Cp*W(NO)(CH₂CMe₃)(η³-CH₂CHCHPh) complex also effects the terminal C-H activation of other alkanes and heteroatom-containing hydrocarbons. The carbonylation of ligands derived from a long-chain alkane and ether has been performed. In addition, the activation of methane, ethane, and propane has been optimized for the compound Cp*W(NO)(CH₂CMe₃)(η³-CH₂CHCHMe). Finally, the bound ketone ligands of complexes Cp*W(NO)(CO)(η²-PhCH=CHCH₂C(=O)(alkyl)) have been photolytically released as the cis and trans β,γ-unsaturated ketone products.

description: This unit was published in „International Cooperation of Competition Authorities in Europe: from Bilateral Agreements to Transgovernmental Networks” Błachucki, M., ed., (2020) In the last five years, opportunities for cooperation among competition authorities, both within regional networks and internationally, have increased considerably, involving even those authorities that were not exposed to this type of activity. In the author’s view, and from his experience at the Italian Competition Authority (the AGCM), mutual trust and familiarity are necessary ingredients for successful coordination and cooperation, even in the presence of legal instruments facilitating the exchange of information with, and/or investigatory assistance from, other cooperating authorities. Therefore, it is argued that, in a world where regional networks and bilateral agreements are of growing importance, multilateral organisations such as the ICN can still play an important role in boosting confidence and trust among competition authorities and developing tailored and cost-effective tools for cooperation.

description: The exact expressions for the characteristics of synchrotron radiation of charged particles in the first excited state are obtained in analytical form using quantum theory methods. We performed a detailed analysis of the angular distribution structure of radiation power and its polarization for particles with spin 0 and 1/2. It is shown that the exact quantum calculations lead to results that differ substantially from the predictions of classical theory.

description: We study the stability properties of the Cauchy horizon for two different self-dual black hole solutions obtained in a model inspired by Loop Quantum Gravity. The self-dual spacetimes depend on a free dimensionless parameter called a polymeric parameter P. For the first metric the Cauchy horizon is stable for supermassive black holes only if this parameter is sufficiently small. For small black holes, however the stability is easily implemented. The second metric analyzed is not only self-dual but also "form-invariant" under the transformation r -> r*^2/r and r* = 2 m P. We find that this symmetry protects the Cauchy horizon for any value of the polymeric parameter.

description: We consider the Cauchy problem for (energy-subcritical) nonlinear Schrödinger equations with sub-quadratic external potentials and an additional angular momentum rotation term. This equation is a well-known model for superfluid quantum gases in rotating traps. We prove global existence (in the energy space) for defocusing nonlinearities without any restriction on the rotation frequency, generalizing earlier results given in [11,12]. Moreover, we find that the rotation term has a considerable influence in proving finite time blow-up in the focusing case.

An investigation in the prevalence of co-axial misalignment of surgical loupes amongst BC dental professionals
Creators: name: Wen, Wen Maggie
Publisher: name: University of British Columbia
Year: 2016

description: Dental surgical loupes have been increasingly popular among dental professionals over the last decade for their visual and postural benefits. In the province of British Columbia, over 60% of dental clinicians practice with surgical loupes and many dental educational institutions have made surgical loupes mandatory for all pre-clinical and clinical students. However, dental professionals will only receive the full benefits of surgical loupes if the loupes are adjusted to fit the individual needs of each clinician. This study examines the co-axial alignment of surgical loupes, one of the three critical criteria for the proper adjustment of these optical systems. A simple quantitative co-axial alignment measurement tool was first developed and then tested for reliability and repeatability. The researcher then measured co-axial alignment of surgical loupes among 97 practicing dental professionals in British Columbia and 23 UBC Dentistry students who currently practice with surgical loupes. The participants were also asked to complete a survey on clinical practice patterns. The results demonstrated that 1) there is a high prevalence (82.5%) of co-axial misalignment of surgical loupes among dental professionals surveyed; 2) dental professionals wearing Front-lens Mounted surgical loupes with full vertical adjustability (FLM w/FVA), Front-lens Mounted surgical loupes with limited adjustability (FLM w/LVA) and Through-the-Lens (TTL) surgical loupes are equally likely to be out of co-axial alignment; 3) FLM w/ FVA are the only loupes that can be adjusted to achieve full co-axial alignment and 4) dental professionals’ perception of their own visual acuity and quality of care are the same for dental professionals using aligned surgical loupes and for those using misaligned surgical loupes. The results from this study establishes a solid foundation for larger-scale studies in the field of surgical magnification and helps the dental communities make informed decisions about their equipment, and will guide surgical loupes manufacturers to develop more evidence-based products.

description: We studied spatial distribution of dynamic nuclear polarization (DNP) in a Hall-bar device in a breakdown regime of the quantum Hall effect (QHE). We detected nuclear magnetic resonance (NMR) signals from the polarized nuclear spins by measuring the Hall voltage $V_{xy}$ using three pairs of voltage probes attached to the conducting channel of the Hall bar. We find that the amplitude of the NMR signal depends on the position of the Hall voltage probes and that the largest NMR signal is obtained from the pair of probes farthest from the electron-injecting electrode. Combined with results on pump-and-probe measurements, we conclude that the DNP induced by QHE breakdown develops along the electron-drift direction.

description: An accurate prediction of the surface potential at the air-water interface is critical to calculating ion hydration free energies and electrochemical half-cell potentials. Using Density Functional Theory (DFT), model interfacial configurations, and a theoretical definition of the surface potential, we report a value of +3.63~volt at 0.92~g/cc water density. A maximally localized Wannier function analysis confirms that the surface potential is dominated by molecular quadrupole (or "spherical second moment") contributions. We find that the predicted surface potential depends on computational details, and conclude that standard DFT codes may not yield surface potentials directly comparable to existing experiments.

description: This unit was published in „International Cooperation of Competition Authorities in Europe: from Bilateral Agreements to Transgovernmental Networks” Błachucki, M., ed., (2020). International cooperation is one of key elements of successfully applying competition rules. As business becomes ever more global, there is an inevitable influence also on the assessment of competition. With increasing numbers of international transactions, powerful multinational companies and international cartels, it is all the more necessary for countries to cooperate with each other. The Antimonopoly Office of the Slovak Republic (hereinafter as the ‘Slovak NCA’) does not operate in isolation; on the contrary,it needs strong support from partnering agencies in various forms, either at a regional level or a global level. A number of different possible forms of international cooperation have developed during the existence of the Slovak NCA. We have recapped our overall experience with all of these (either positive or unsuccessful) in the article. The ambition of the article is further to review the existing obstacles to closer cooperation, uncover the main reasons behind unsuccessful attempts at cooperation, and at the same time find a way past these obstacles. The new Directive 2019/1, dealing with strengthening the NCAs’ powers might be an important step towards more effective cooperation. The Slovak NCA’s approach to the amendment of its legislation is described in the article.

description: This unit was published in „International Cooperation of Competition Authorities in Europe: from Bilateral Agreements to Transgovernmental Networks” Błachucki, M., ed., (2020). Over the last 15 to 20 years, compliance in the corporate sector has taken a very dynamic development. Hardly any company, and least all of the large and multinational companies, can manage without an individual compliance policy and company-wide compliance programmes, which is also a sign of good corporate citizenship. The implementation of effective antitrust compliance programmes plays an important role for companies seeking to comply with antitrust rules and regulations. An increasing number of jurisdictions have introduced the possibility to use effective antitrust compliance programmes as a mitigating factor for calculating the fines for antitrust violations. To this end, companies need to know the regulator‘s expectations as to the components of an effective antitrust compliance programme. The following article looks at the decisive elements for such a programme. It refers especially to the new and relatively detailed guidance that has been issued by the Antitrust Division of the U.S. Department of Justice. In 2019, the DOJ gave up its longstanding policy of categorically rejecting any consideration of effective antitrust compliance programmes and announced a landmark policy shift through acknowledging the positive aspects of such programmes. For regulators, in order to promote competition, it is still necessary to cooperate and harmonise their activities to strike the right balance between positive and negative incentives for companies seeking to comply with antitrust rules and regulations. Leniency programmes and antitrust compliance programmes are the cornerstones of preserving the positive impacts of effective competition on social and economic wealth of a society.

description: Magnetic properties of uranium and neptunium compounds showing the coexistence of Kondo screening effect and ferromagnetic order are investigated within the Anderson lattice Hamiltonian with a two-fold degenerate $f$-level in each site, corresponding to $5f^2$ electronic configuration with $S=1$ spins. A derivation of the Schrieffer-Wolff transformation is presented and the resulting Hamiltonian has an effective $f$-band term, in addition to the regular exchange Kondo interaction between the $S=1$ $f$-spins and the $s=1/2$ spins of the conduction electrons. The obtained effective Kondo lattice model can describe both the Kondo regime and a weak delocalization of $5f$-electron. Within this model we compute the Kondo and Curie temperatures as a function of model parameters, namely the Kondo exchange interaction constant $J_K$, the magnetic intersite exchange interaction $J_H$ and the effective $f$-bandwidth. We deduce, therefore, a phase diagram of the model which yields the coexistence of Kondo effect and ferromagnetic ordering and also accounts for the pressure dependence of the Curie temperature of uranium compounds such as UTe.

Global Well-Posedness and Scattering for the Defocusing Energy-Supercritical Cubic Nonlinear Wave Equation
Creators: name: Bulut, Aynur

Year: 2010
Subjects: subject: Analysis of PDEs (math.AP)

description: In this paper, we consider the defocusing cubic nonlinear wave equation $u_{tt}-Δu+|u|^2u=0$ in the energy-supercritical regime, in dimensions $d\geq 6$, with no radial assumption on the initial data. We prove that if a solution satisfies an a priori bound in the critical homogeneous Sobolev space throughout its maximal interval of existence, that is, $u\in L_t^\infty(\dot{H}_x^{s_c}\times\dot{H}_x^{s_c-1})$, then the solution is global and it scatters. Our analysis is based on the methods of the recent works of Kenig-Merle \cite{KenigMerleSupercritical} and Killip-Visan \cite{KillipVisanSupercriticalNLS,KillipVisanSupercriticalNLW3D} treating the energy-supercritical nonlinear Schrödinger and wave equations.

description: A variety of studies have modeled the physics of material deformation and damage as examples of generalized phase transitions, involving either critical phenomena or spinodal nucleation. Here we study a model for frictional sliding with long range interactions and recurrent damage that is parameterized by a process of damage and partial healing during sliding. We introduce a failure threshold weakening parameter into the cellular-automaton slider-block model which allows blocks to fail at a reduced failure threshold for all subsequent failures during an event. We show that a critical point is reached beyond which the probability of a system-wide event scales with this weakening parameter. We provide a mapping to the percolation transition, and show that the values of the scaling exponents approach the values for mean-field percolation (spinodal nucleation) as lattice size $L$ is increased for fixed $R$. We also examine the effect of the weakening parameter on the frequency-magnitude scaling relationship and the ergodic behavior of the model.

On the structure of optimal martingale transport in higher dimensions
Creators: name: Lim, Tongseok
Publisher: name: University of British Columbia
Year: 2016

description: In the first part of this thesis, we study the structure of solutions to the optimal martingale transport problem, when the marginals lie in higher dimensional Euclidean spaces (ℝ^d, d ≥ 2). The problem has been extensively studied in one-dimensional space (ℝ), but few results have been shown in higher dimensions. In this thesis, we propose two conjectures and provide key ideas that lead to solutions in important cases. In the second part, we study the structure of solutions to the optimal subharmonic martingale transport problem, again when the marginals lie in higher dimensional Euclidean spaces. First, we show that this problem has an equivalent formulation in terms of the celebrated Skorokhod embedding problem in probability theory. We then describe the fine structure of the solution provided the marginals are radially symmetric. The general case remains unsolved, and its potential solution calls for a deeper understanding of harmonic analysis and Brownian motion in higher dimensional spaces.

description: The polarization of x-rays plays an outstanding role in experimental techniques such as non-resonant magnetic x-ray scattering and resonant x-ray scattering of magnetic and multipolar order. Different instrumental methods applied to synchrotron light can transform its natural polarization into an arbitrary polarization state. Several synchrotron applications, in particular in the field of magnetic and resonant scattering rely on the improvement in the signal/noise ratio or the deeper insight into the ordered state and the scattering process made possible through these polarization techniques. Here, we present the mathematical framework for the description of fully and partially polarized x-rays, with some applications such as linear x-ray polarization analysis for the determination of the scattered beam's polarization, and the Ge K-edge resonant scattering.

description: Self-organization of proteins in space and time is of crucial importance for the functioning of cellular processes. Often, this organization takes place in the presence of strong random fluctuations due to the small number of molecules involved. We report on stochastic switching of the Min-protein distributions between the two cell halves in short Escherichia coli cells. A computational model provides strong evidence that the macroscopic switching is rooted in microscopic noise on the molecular scale. In longer bacteria, the switching turns into regular oscillations that are required for positioning of the division plane. As the pattern becomes more regular, cell-to-cell variability also lessens, indicating cell length-dependent regulation of Min-protein activity.

description: We report our discovery of NLTT 20346 as an M5+M6 companion system to the tight binary (or triple) L dwarf 2MASS J0850359+105716. This nearby (~31 pc), widely separated (~7700 AU) quadruple system was identified through a cross-match of proper motion catalogs. Follow-up imaging and spectroscopy of NLTT 20346 revealed it to be a magnetically active M5+M6 binary with components separated by ~2" (50-80 AU). Optical spectroscopy of the components show only moderate Halpha emission corresponding to a statistical age of ~5 - 7 Gyr for both M dwarfs. However NLTT 20346 is associated with the XMM-Newton source J085018.9+105644, and based on X-ray activity the age of NLTT 20346 is between 250-450 Myr. Strong Li absorption in the optical spectrum of 2MASS J0850+1057 indicates an upper age limit of 0.8 - 1.5 Gyr favoring the younger age for the primary. Using evolutionary models in combination with an adopted system age of 0.25-1.5 Gyr indicates a total mass for 2MASS J0850+1057 of 0.07+/-0.02 Msun if it is a binary. NLTT 20346/2MASS J0850+1057 joins a growing list of hierarchical systems containing brown dwarf binaries and is among the lowest binding energy associations found in the field. Formation simulations via gravitational fragmentation of massive extended disks have successfully produced a specific analog to this system.

description: We consider holomorphic mappings $H$ between a smooth real hypersurface $M\subset \bC^{n+1}$ and another $M'\subset \bC^{N+1}$ with $N\geq n$. We provide conditions guaranteeing that $H$ is transversal to $M'$ along all of $M$. In the strictly pseudoconvex case, this is well known and follows from the classical Hopf boundary lemma. In the equidimensional case ($N=n$), transversality holds for maps of full generic rank provided that the source is of finite type in view of recent results by the authors (see also a previous paper by the first author and L. Rothschild). In the positive codimensional case ($N>n$), the situation is more delicate as examples readily show. In recent work by S. Baouendi, the first author, and L. Rothschild, conditions were given guaranteeing that the map $H$ is transversal outside a proper subvariety of $M$, and examples were given showing that transversality may fail at certain points. One of the results in this paper implies that if $N\le 2n-2$, $M'$ is Levi-nondegenerate, and $H$ has maximal rank outside a complex subvariety of codimension 2, then $H$ is transversal to $M'$ at all points of $M$. We show by examples that this conclusion fails in general if $N\geq 2n$, or if the set $W_H$ of points where $H$ is not of maximal rank has codimension one. We also show that $H$ is transversal at all points if $H$ is assumed to be a finite map (which allows $W_H$ to have codimension one) and the stronger inequality $N\leq 2n-3$ holds, provided that $M$ is of finite type.

Evolution of white dwarf stars with high-metallicity progenitors: the role of 22Ne diffusion

description: Motivated by the strong discrepancy between the main sequence turn-off age and the white dwarf cooling age in the metal-rich open cluster NGC 6791, we compute a grid of white dwarf evolutionary sequences that incorporates for the first time the energy released by the processes of 22Ne sedimentation and of carbon/oxygen phase separation upon crystallization. The grid covers the mass range from 0.52 to 1.0 Msun, and it is appropriate for the study of white dwarfs in metal-rich clusters. The evolutionary calculations are based on a detailed and self-consistent treatment of the energy released from these two processes, as well as on the employment of realistic carbon/oxygen profiles, of relevance for an accurate evaluation of the energy released by carbon/oxygen phase separation. We find that 22Ne sedimentation strongly delays the cooling rate of white dwarfs stemming from progenitors with high metallicities at moderate luminosities, whilst carbon/oxygen phase separation adds considerable delays at low luminosities. Cooling times are sensitive to possible uncertainties in the actual value of the diffusion coefficient of 22Ne. Changing the diffusion coefficient by a factor of 2, leads to maximum age differences of approx. 8-20% depending on the stellar mass. We find that the magnitude of the delays resulting from chemical changes in the core is consistent with the slow down in the white dwarf cooling rate that is required to solve the age discrepancy in NGC 6791.

Microscopic Mechanism for Staggered Scalar Order in PrFe4P12

description: A microscopic model is proposed for the scalar order in PrFe4P12 where f2 crystalline electric field (CEF) singlet and triplet states interact with two conduction bands. By combining the dynamical mean-field theory and the continuous-time quantum Monte Carlo, we obtain an electronic order with staggered Kondo and CEF singlets with the total conduction number being unity per site. The ground state becomes semimetallic provided that the two conduction bands have different occupation numbers. This model naturally explains experimentally observed properties in the ordered phase of PrFe4P12 such as the scalar order parameter, temperature dependence of the resistivity, field-induced staggered moment, and inelastic features in neutron scattering. The Kondo effect plays an essential role for ordering, in strong contrast with ordinary magnetic orders by the RKKY interaction.

description: The random transitions of ion channels between conducting and non-conducting states generate a source of internal fluctuations in a neuron, known as channel noise. The standard method for modeling fluctuations in the states of ion channels uses continuous-time Markov chains nonlinearly coupled to a differential equation for voltage. Beginning with the work of Fox and Lu, there have been attempts to generate simpler models that use stochastic differential equation (SDEs) to approximate the stochastic spiking activity produced by Markov chain models. Recent numerical investigations, however, have raised doubts that SDE models can preserve the stochastic dynamics of Markov chain models. We analyze three SDE models that have been proposed as approximations to the Markov chain model: one that describes the states of the ion channels and two that describe the states of the ion channel subunits. We show that the former channel-based approach can capture the distribution of channel noise and its effect on spiking in a Hodgkin-Huxley neuron model to a degree not previously demonstrated, but the latter two subunit-based approaches cannot. Our analysis provides intuitive and mathematical explanations for why this is the case: the temporal correlation in the channel noise is determined by the combinatorics of bundling subunits into channels, and the subunit-based approaches do not correctly account for this structure. Our study therefore confirms and elucidates the findings of previous numerical investigations of subunit-based SDE models. Moreover, it presents the first evidence that Markov chain models of the nonlinear, stochastic dynamics of neural membranes can be accurately approximated by SDEs. This finding opens a door to future modeling work using SDE techniques to further illuminate the effects of ion channel fluctuations on electrically active cells.

Induced seismicity and corrosion vulnerability assessment of oil and gas pipelines using a Bayesian belief network model
Creators: name: Shabarchin, Oleg
Publisher: name: University of British Columbia
Year: 2016

description: A substantial amount of oil and gas products are transported and distributed via pipelines, which can stretch for thousands of kilometers. Because of the adverse environmental impact and significant financial losses, the integrity of these pipelines is essential. British Columbia Oil and Gas Commission (BCOGC) has indicated metal loss due to corrosion as one of the primary causes of pipeline failures. Therefore, it is important to identify pipelines subjected to severe corrosion in order to improve corrosion mitigation and pipeline maintenance strategies, thus minimizing the likelihood of failure. To accomplish this task, this thesis presents a Bayesian belief network (BBN)-based probabilistic corrosion hazard assessment approach for oil and gas pipelines. A cause-effect BBN model has been developed by considering various types of information, such as analytical corrosion models, expert knowledge and published literature. Multiple corrosion models and failure pressure models have been incorporated into a single flexible network in order to estimate corrosion defects and the associated probability of failure. Besides corrosion hazard, BCOGC has reported multiple cases of anthropogenic seismicity, which also may compromise the pipeline integrity. To this end, this thesis explores the potential impact of induced seismicity on the oil and gas pipeline infrastructure. Spatial clustering analysis is used for earthquakes, previously registered in the region, to delineate areas, which are particularly prone to the induced seismicity. The state of the art ground motion prediction equation for induced seismicity is applied in a Monte Carlo simulation to obtain a stochastic field of the seismic intensity. Based on the established seismic fragility formulations for pipelines and mechanical characteristics as well as corrosion conditions, spatial and probabilistic distributions of the repair rate and probability of failure have been obtained and visualized with the aid of the Geographic Information System. The proposed model can help to identify vulnerable pipeline sections and rank them accordingly to enhance the informed decision making process. To demonstrate the application of the proposed approach, two case studies for the Northeastern British Columbia oil and gas pipeline infrastructure are presented.
