description: Below you can see an animated gif about the COVID-19 intensification-of-the-outbreak map in the summer of 2021 in Iran. 1. The prevalence clearly follows a geographical pattern. 2- The outbreak starts from the southeast coast and then slowly covers the whole country. 3- Places that have the beginning of summer earlier, see the intensification of the outbreak sooner. 4- The places that are high and the ridge of the mountains of Zagros are witnessing the outbreak later and are out of the outbreak sooner. This evidence supports the theory that: 1. Although SARS-CoV-2 is an infectious disease, after almost two years of rotation of the virus in the community, its intensification does not follow only the patterns of viral transmission. Environmental factors, such as the concentration of oceanic iodine in the atmosphere, can affect the severity of the syndrome through the body's hormonal mechanisms. 2- With the beginning of summer season in an area, air currents change from the upper floors of the atmosphere to the lower floors. This could cause the redistribution of oceanic iodine from the Indian Ocean (the southeast coasts of Iran) gradually over the entire plateau of Iran. 3- In the very high areas of the Zagros ridge, where the summer heat starts later and ends earlier, the flow of oceanic iodine from the atmosphere to the earth is strengthened later and weakened sooner. This theory and its evidence suggest that the climatic factor (the concentration of oceanic iodine in the air) intensifies or weakens the hormonal mechanisms associated with SARS-CoV-2 syndrome (along with the infectious agent).

description: The nature of type Ia supernovae (SNe Ia) is still unclear. Employing Eggleton's stellar evolution code with the optically thick wind assumption, we systematically studied the He star donor channel of SNe Ia, in which a carbon-oxygen white dwarf accretes material from a He main-sequence star or a He subgiant to increase its mass to the Chandrasekhar mass. We mapped out the initial parameters for producing SNe Ia in the orbital period--secondary mass plane for various WD masses from this channel. According to a detailed binary population synthesis approach, we find that this channel can produce SNe Ia with short delay times (~100Myr) implied by recent observations. We obtained many properties of the surviving companions of this channel after SN explosion, which can be verified by future observations. We also find that the surviving companions from the SN explosion scenario have a high spatial velocity (>400km/s), which could be an alternative origin for hypervelocity stars (HVSs), especially for HVSs such as US 708.

By combining this result with its analogue relevant to hadron-hadron collisions, we obtain NLO predictions matched to parton showers for the photoproduction of QQ^{-} pairs.

Approximate Solutions to Fractional Subdiffusion Equations: The heat-balance integral method
Creators: name: Hristov, Jordan
Publisher: name: arXiv
Year: 2011
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: The work presents integral solutions of the fractional subdiffusion equation by an integral method, as an alternative approach to the solutions employing hypergeometric functions. The integral solution suggests a preliminary defined profile with unknown coefficients and the concept of penetration (boundary layer). The prescribed profile satisfies the boundary conditions imposed by the boundary layer that allows its coefficients to be expressed through its depth as unique parameter. The integral approach to the fractional subdiffusion equation suggests a replacement of the real distribution function by the approximate profile. The solution was performed with Riemann -Liouville time-fractional derivative since the integral approach avoids the definition of the initial value of the time-derivative required by the Laplace transformed equations and leading to a transition to Caputo derivatives. The method is demonstrated by solutions to two simple fractional subdiffusion equations (Dirichlet problems): 1) Time-Fractional Diffusion Equation, and 2) Time-Fractional Drift Equation, both of them having fundamental solutions expressed through the M-Write function. The solutions demonstrate some basic issues of the suggested integral approach, among them: a) Choice of the profile, b) Integration problem emerging when the distribution (profile) is replaced by a prescribed one with unknown coefficients; c) Optimization of the profile in view to minimize the average error of approximations; d) Numerical results allowing comparisons to the known solutions expressed to the M-Write function and error estimations.

Mechanistic jet impingement model for cooling of hot steel plates

Publisher: name: University of British Columbia
Year: 2014

description: Accelerated cooling on the run-out table of a hot rolling mill is a key technology to tailor microstructure and properties of advanced steels. Thus, it is crucial to develop accurate heat transfer models in order to predict the temperature history of the steel plates on run-out tables. The present study describes a strategy to develop a mechanistic cooling model to simulate the temperature of the plate cooled by top water nozzles on a run-out table. Systematic experiments have been carried out on a pilot scale run-out table facility using two types of top nozzles: planar (curtain) and circular (axisymmetric) nozzles. Experimental results for cooling of stationary plates showed that the heat transfer rate depends strongly on the distance from the jet especially in the temperature range where the transition boiling regime occurs. Based on experimental results, a boiling curve model has been proposed that takes into account boiling heat transfer mechanisms and maps local boiling curves for cooling of stationary steel plates. The effects of water flow rate and water temperature on the heat extraction from the plate have been included in the model. Then, systematic experimental heat transfer studies were conducted to investigate the effect of plate speed on the heat transfer rate. It was found that the plate motion influences the heat transfer rate in the film boiling and transition boiling regimes; however, it does not have an effect on the heat flux in the nucleate boiling regime. Moreover, for the circular nozzle system, it was found that the nucleate boiling heat flux does not change with lateral distance. However, heat flux in the film boiling and transition boiling regimes decreases with increasing distance from the longitudinal centerline of the plate. In the next step, a cooling model was proposed by accounting for the boiling curves of single nozzle cooling for moving plates. Transient heat conduction within the plate was analyzed and surface heat flux and temperature histories were predicted. The validity of the cooling model was examined with multiple nozzles experimental data from the literature. Very good agreement with experimental results has been obtained.

description: We identify a high frequency of Type 1 XUV disks, reflecting recent outer disk star formation, in a sample of 31 E/S0s with stellar masses primarily below M_* ~ 4 x 10^10 M_sun. Our ~40% identification rate is roughly twice the 20% fraction reported for late-type galaxies. Intriguingly, in the dwarf mass regime (below M_* ~ 5 x 10^9 M_sun) where gas fractions clearly rise, Type 1 XUV disks occur in ~70% of red-sequence E/S0s but only ~20% of blue-sequence E/S0s, a population recently linked to active disk rebuilding, especially in the dwarf regime. Our statistics are preliminary, but could indicate that for dwarf E/S0s Type 1 XUV disks are primarily related to weak or inefficient outer-disk star formation rather than to star formation capable of driving substantial disk growth. Substantial growth may instead be associated with populations that have low XUV-disk frequency, possibly explaining the similar ~20% frequencies for normal late types and low-mass blue-sequence E/S0s.

description: Na5Cu3O6, a new member of one dimensional charge ordered chain cuprates, was synthesized via the azide/nitrate route by reacting NaN3, NaNO3 and CuO. According to single crystal X-ray analysis, one dimensional CuO2 chains built up from planar, edge-sharing CuO4 squares are a dominant feature of the crystal structure. From the analysis of the Cu-O bond lengths we find that the system forms a Wigner lattice. The commensurate charge order allows to explicitly assign the valence states of either +2 or +3 to each copper atom resulting in a repetition according to Cu(2+)-Cu(3+)-Cu(2+)-Cu(2+)-Cu(3+)-Cu(2+). Following the theoretical analysis of the previously synthesized compounds Na3Cu2O4 and Na8Cu5O10, the magnetic susceptibility was expected to show a large dimer gap. Surprisingly, this is not the case. To resolve this puzzle, we show that the magnetic couplings in this compound are strongly affected by excitations across the Wigner charge gap. By including these contributions, which are distinct from conventional superexchange in Mott-insulators, we obtain a quantitative satisfying theoretical description of the magnetic susceptibility data.

description: The recently developed structure model that uses the generator coordinate method to perform configuration mixing of angular-momentum projected wave functions, generated by constrained self-consistent relativistic mean-field calculations for triaxial shapes (3DAMP+GCM), is applied in a systematic study of ground states and low-energy collective states in the even-even magnesium isotopes $^{20-40}$Mg. Results obtained using a relativistic point-coupling nucleon-nucleon effective interaction in the particle-hole channel, and a density-independent $δ$-interaction in the pairing channel, are compared to data and with previous axial 1DAMP+GCM calculations, both with a relativistic density functional and the non-relativistic Gogny force. The effects of the inclusion of triaxial degrees of freedom on the low-energy spectra and E2 transitions of magnesium isotopes are examined.

It is expected that at LHC the chiral magnetic effect will be about 20 times weaker than at RHIC. At lower energy range this effect should vanish sharply at energy somewhere above the top SPS one. To elucidate CME background effects a transport model including magnetic field evolution is put forward.

description: The $k_\perp$-moment of a quark's Sivers function is known to be related to the corresponding twist-three quark-gluon correlation function $T_{q,F}(x, x)$. The two functions have been extracted from data for single-spin asymmetries in semi-inclusive deep inelastic scattering and in single-inclusive hadron production in $pp$ collisions, respectively. Performing a consistent comparison of the extracted functions, we find that they show a "sign mismatch": while the magnitude of the functions is roughly consistent, the $k_\perp$-moment of the Sivers function has opposite sign from that of $T_{q,F}(x, x)$, both for up and for down quarks. Barring any inconsistencies in our theoretical understanding of the Sivers functions and their process dependence, the implication of this mismatch is that either, the Sivers effect is not dominantly responsible for the observed single-spin asymmetries in $pp$ collisions or, the current semi-inclusive lepton scattering data do not sufficiently constrain the $k_\perp$-moment of the quark Sivers functions. Both possibilities strengthen the case for further experimental investigations of single-spin asymmetries in high-energy $pp$ and $ep$ scattering.

description: Characterization of migration in gravitationally unstable disks is necessary to understand the fate of protoplanets formed by disk instability. As part of a larger study, we are using a 3D radiative hydrodynamics code to investigate how an embedded gas giant planet interacts with a gas disk that undergoes gravitational instabilities (GIs). This Letter presents results from simulations with a Jupiter-mass planet placed in orbit at 25 AU within a 0.14 $M_{\odot}$ disk. The disk spans 5 to 40 AU around a 1 $M_{\odot}$ star and is initially marginally unstable. In one simulation, the planet is inserted prior to the eruption of GIs; in another, it is inserted only after the disk has settled into a quasi-steady GI-active state, where heating by GIs roughly balances radiative cooling. When the planet is present from the beginning, its own wake stimulates growth of a particular global mode with which it strongly interacts, and the planet plunges inward six AU in about 10$^3$ years. In both cases with embedded planets, there are times when the planet's radial motion is slow and varies in direction. At other times, when the planet appears to be interacting with strong spiral modes, migration both inward and outward can be relatively rapid, covering several AUs over hundreds of years. Migration in both cases appears to stall near the inner Lindblad resonance of a dominant low-order mode. Planet orbit eccentricities fluctuate rapidly between about 0.02 to 0.1 throughout the GI-active phases of the simulations.

description: We investigate the QCD phase diagram based on the strong coupling expansion of the lattice QCD with one species of the staggered fermions at finite temperature (T) and chemical potential (mu). We analytically derive an effective potential including both chiral and deconfinement (Z_3) dynamics with finite coupling effects in mean-field approximations. We focus on Polyakov loop properties in whole T-mu plane, and study relations between the chiral and deconfinement crossovers. At a fixed large mu, sequencial rapid variations of the Polyakov loop are observed with increasing T. It is natural to interprete them as the "chiral induced" and "Z_3 induced" deconfinement crossovers.

description: We introduce two-level discounted games played by two players on a perfect-information stochastic game graph. The upper level game is a discounted game and the lower level game is an undiscounted reachability game. Two-level games model hierarchical and sequential decision making under uncertainty across different time scales. We show the existence of pure memoryless optimal strategies for both players and an ordered field property for such games. We show that if there is only one player (Markov decision processes), then the values can be computed in polynomial time. It follows that whether the value of a player is equal to a given rational constant in two-level discounted games can be decided in NP intersected coNP. We also give an alternate strategy improvement algorithm to compute the value.

description: Kamihara and coworkers' report of superconductivity at Tc = 26 K in fluorine-doped LaFeAsO inspired a worldwide effort to understand the nature of the superconductivity in this new class of compounds. These iron pnictide and chalcogenide (FePn/Ch) superconductors have Fe electrons at the Fermi surface, plus an unusual Fermiology that can change rapidly with doping, which lead to normal and superconducting state properties very different from those in standard electron-phonon coupled 'conventional' superconductors. Clearly superconductivity and magnetism/magnetic fluctuations are intimately related in the FePn/Ch - and even coexist in some. Open questions, including the superconducting nodal structure in a number of compounds, abound and are often dependent on improved sample quality for their solution. With Tc values up to 56 K, the six distinct Fe-containing superconducting structures exhibit complex but often comparable behaviors. The search for correlations and explanations in this fascinating field of research would benefit from an organization of the large, seemingly disparate data set. This review attempts to provide an overview, using numerous references, with a focus on the materials and their superconductivity.

description: Detailed properties of resonance fluorescence from a single quantum dot in a micropillar cavity are investigated, with particular focus on emission coherence in dependence on optical driving field power and detuning. Power-dependent series over a wide range could trace characteristic Mollow triplet spectra with large Rabi splittings of $|Ω| \leq 15$ GHz. In particular, the effect of dephasing in terms of systematic spectral broadening $\propto Ω^2$ of the Mollow sidebands is observed as a strong fingerprint of excitation-induced dephasing. Our results are in excellent agreement with predictions of a recently presented model on phonon-dressed QD Mollow triplet emission in the cavity-QED regime.

description: Graph games of infinite length are a natural model for open reactive processes: one player represents the controller, trying to ensure a given specification, and the other represents a hostile environment. The evolution of the system depends on the decisions of both players, supplemented by chance. In this work, we focus on the notion of randomised strategy. More specifically, we show that three natural definitions may lead to very different results: in the most general cases, an almost-surely winning situation may become almost-surely losing if the player is only allowed to use a weaker notion of strategy. In more reasonable settings, translations exist, but they require infinite memory, even in simple cases. Finally, some traditional problems becomes undecidable for the strongest type of strategies.
Seed oil, seed coat mucilage and cuticular wax deposition are interconnected in Arabidopsis thaliana
Creators: name: Shi, Lin
Publisher: name: University of British Columbia
Year: 2015

description: Seed oil, seed coat mucilage and cuticular wax are plant-specific metabolites important for plant development and growth. Therefore, understanding biosynthesis, deposition, transport and regulation of these metabolites will benefit our daily life and the environment. The original objectives of my thesis research were to investigate the regulation of seed oil accumulation by a transcription factor GLABRA2 (GL2; chapter 2) and to explore the secretory process involved in the transport of cuticular waxes from the endoplasmic reticulum to the plasma membrane (chapter 3) in Arabidopsis thaliana. However, my research revealed two unexpected connections between seed oil and seed coat mucilage deposition and between cuticular wax export and cell wall formation. At the beginning of chapter 2, I hypothesized that GL2 may regulate seed oil biosynthesis by controlling PHOSPHOLIPASE D ZETA (PLDZ) genes in the embryo. However, my data demonstrated that GL2, and all of the transcription factors known to be required for GL2 expression, influence seed oil accumulation in the embryo by regulating transcription of a seed coat mucilage biosynthetic gene, MUCILAGE MODIFIED 4 (MUM4) in the seed coat. Based on this evidence, I propose that mucilage biosynthesis in the seed coat competes with oil biosynthesis in the embryo for available photosynthate during seed development. This information suggests a promising way to engineer high oil yields in seeds by blocking seed coat mucilage production. In chapter 3, I characterized deposition of stem cuticular wax, seed coat mucilage and secondary cell wall columella, and secretion in the cer11-1 mutant. The pleiotropic cer11-1 phenotype suggests that CER11 plays a role in secretory trafficking involved in the deposition of apoplastic matrix components, including cuticular wax, seed coat mucilage and cell wall constituents. Cloning of the CER11 gene revealed that it encodes C-TERMINAL DOMAIN PHOSPHATASE LIKE 2 (CPL2) that interacts with a vacuolar type H⁺-ATPase (V-ATPase) subunit C (VHA-C) in yeast and plants. I hypothesize that the role of the CER11/CPL2 in secretory trafficking is to determine phosphorylation levels of VHA-C involved in regulation of V-ATPase activity.

description: Let the adiabatic invariant of action variable in slow-fast Hamiltonian system with two degrees of freedom have two limiting values along the trajectories as time tends to infinity. The difference of two limits is exponentially small in analytic systems. An iso-energetic reduction and canonical transformations are applied to transform the slow-fast systems to form of systems depending on slowly varying parameters in a complexified phase space. On the basis of this method an estimate for the accuracy of conservation of adiabatic invariant is given for such systems.

The need to belong and health promotion
Creators: name: Dowd, Anna Justine
Publisher: name: University of British Columbia
Year: 2014

description: The overall purpose of this PhD thesis was to examine the need to belong and a sense of belonging in relation to health-enhancing cognitions and behaviours. In chapter 1, an overview is provided of the need to belong and a sense of belonging in relation to human behaviour. Next, in chapter 2, the findings are presented from two studies that examined the effectiveness of framing exercise as a means of boosting social skills (versus health benefits) for increasing self-regulatory efficacy, exercise intentions, and exercise behaviour among socially isolated individuals. Results from Study 1 revealed that the social skills manipulation led to greater self-regulatory efficacy (but not exercise intentions). In Study 2, all participants reported engaging in more exercise; however, those in the social skills condition also reported a greater sense of belonging than those in the health benefits comparison condition. Chapters 3, 4 and 5 present findings from a program evaluation that sought to examine a group-based mentorship lifestyle program for adolescent girls, which aims to foster a sense of belonging among participants. In chapter 3, results from the outcome evaluation are presented in which participants reported significant increases in health enhancing cognitions and behaviours at the end of, and 7 weeks after, program completion. Findings discussed in chapter 4 revealed that participants’ cognitions at the end of the program prospectively predicted physical activity and healthy eating behaviour 7 weeks after program completion. In chapter 5, findings from a qualitative interview-based study indicated that participants enjoyed the program, reported changes in important health-enhancing cognitions and behaviours and developed meaningful relationships with program mentors and other program participants (i.e., a sense of connection to the program). Finally, a summary is provided in chapter 6 of the novel contributions of this research as well as limitations and future directions for inquiry. In conclusion, the research presented within this dissertation demonstrates that the need to belong can be used to improve health-enhancing cognitions and exercise behaviour (chapter 2) and feelings of belonging are an important component of effective mentoring programs that target health behaviours among adolescent girls (chapters 3, 4 and 5).

description: We analyze the equilibrium properties of a weakly interacting, trapped quasi-one-dimensional Bose gas at finite temperatures and compare different theoretical approaches. We focus in particular on two stochastic theories: a number-conserving Bogoliubov (ncB) approach and a stochastic Gross-Pitaevskii equation (sGPe) that have been extensively used in numerical simulations. Equilibrium properties like density profiles, correlation functions, and the condensate statistics are compared to predictions based upon a number of alternative theories. We find that due to thermal phase fluctuations, and the corresponding condensate depletion, the ncB approach loses its validity at relatively low temperatures. This can be attributed to the change in the Bogoliubov spectrum, as the condensate gets thermally depleted, and to large fluctuations beyond perturbation theory. Although the two stochastic theories are built on different thermodynamic ensembles (ncB: canonical, sGPe: grand-canonical), they yield the correct condensate statistics in a large BEC (strong enough particle interactions). For smaller systems, the sGPe results are prone to anomalously large number fluctuations, well-known for the grand-canonical, ideal Bose gas. Based on the comparison of the above theories to the modified Popov approach, we propose a simple procedure for approximately extracting the Penrose-Onsager condensate from first- and second-order correlation functions that is computationally convenient. This also clarifies the link between condensate and quasi-condensate in the Popov theory of low-dimensional systems.

description: Hoards of Polish, Lithuanian and Polish-Lithuanian Coins of the 16th-17th centuries discovered on the territory of Georgia The history of Georgian-Polish and Georgian-Lithuanian relations has more than five centuries. The foundations of these connections were laid back in 1494, when the ambassador of the Georgian king Constantine II Bagrationi (1447-1505) visited Poland and Lithuania and conveyed the letter of his mo­narch to their rulers. From the 16th century to the beginning of the second half of the 17th century, widespread use in Georgia received silver money signs of the Kingdom of Poland, the Grand Duchy of Lithuania, and then (since 1569) – Rze­c­zpospolita, that is, united Polish-Lithuanian Commonwealth. As it turns out, the composition of the hoards of European coins found on the territory of Georgia allows us to conclude that silver coins of small denomination were circulating here – half grosses, grosses, poltoraks, troyaks and orts, minted at different times in the Kingdom of Poland, the Grand Duchy of Lithuania and the united Polish-Lithuanian state, along with the gold ducats, were silver thalers, Orts and poltoraks of Brandenburg-Prussia. This, in turn, testifies to the fact that there were rather close political, trade and economic relations between the Georgian kingdoms and principalities with Poland and Lithuania, and then with Rzeczpospolita.

description: We design a novel algorithm for solving Mean-Payoff Games (MPGs). Besides solving an MPG in the usual sense, our algorithm computes more information about the game, information that is important with respect to applications. The weights of the edges of an MPG can be thought of as a gained/consumed energy -- depending on the sign. For each vertex, our algorithm computes the minimum amount of initial energy that is sufficient for player Max to ensure that in a play starting from the vertex, the energy level never goes below zero. Our algorithm is not the first algorithm that computes the minimum sufficient initial energies, but according to our experimental study it is the fastest algorithm that computes them. The reason is that it utilizes the strategy improvement technique which is very efficient in practice.

Pathogen-induced inflammation in immunocompromised conditions
Creators: name: McDonald, Allison
Publisher: name: University of British Columbia
Year: 2014

description: Primary immunodeficiencies arise from genetic anomalies and can cause aberrant inflammation, tissue destruction, and uncontrolled infections. Defects in immunity often first present as cases of recurrent or severe infections with unusual pathogens. Patients with chronic granulomatous disease (CGD) have mutations in the NADPH oxidase that prevent the formation of reactive oxygen species (ROS) critical for effective immunity. We investigated the phagocyte response to Burkholderia cenocepacia, which causes severe lung infections in patients with CGD. B. cenocepacia survived within ROS-deficient neutrophils and induced rapid cell death that was not observed by infection with other bacteria, including other CGD pathogens. Increased cell death was associated with enhanced caspase-3 activation and phosphatidylserine surface exposure compared to healthy neutrophils, both hallmarks of apoptotic programmed cell death. Caspase activation was required to induce increased neutrophil death in the absence of ROS. B. cenocepacia-induced apoptotic neutrophils were pro-inflammatory to macrophages, especially in the absence of ROS, inducing the secretion of IL-6, IL-8, and TNF-α but not the anti-inflammatory cytokines IL-10 or TGF-β from human macrophages. Surprisingly, macrophages enhanced the growth of B. cenocepacia by providing a nutrient-rich intracellular replication niche that allowed the bacteria to escape from normal neutrophil killing. We also report here two sisters with an underlying immunodeficiency who presented with fatal neurodegeneration triggered by infections. Whole exome sequencing identified mutations in perforin1, involved in the granule-mediated cytotoxicity pathway for eliminating infected host cells. Perforin1 mutations are associated with familial hemophagocytic lymphohistiocytosis (FHL). In contrast to FHL, these girls did not have hematopathology or elevated cytokine overproduction. However, 3 years after disease onset, the proband had markedly deficient cytokine production, including IL-1β production following stimulation with a panel of bacterial ligands. These observations extend the spectrum of disease associated with perforin mutations to immune-mediated neurodegeneration triggered by infection. Studies that investigate how opportunistic pathogens cause disease aim to decrease morbidity and mortality in immunocompromised patients and also provide the opportunity to better understand the molecular mechanisms that allow healthy individuals to combat disease.

description: We prove that the countable intersection of $C^1$-diffeomorphic images of certain Diophantine sets has full Hausdorff dimension. For example, we show this for the set of badly approximable vectors in $\mathbb{R}^d$, improving earlier results of Schmidt and Dani. To prove this, inspired by ideas of McMullen, we define a new variant of Schmidt's $(α, β)$-game and show that our sets are hyperplane absolute winning (HAW), which in particular implies winning in the original game. The HAW property passes automatically to games played on certain fractals, thus our sets intersect a large class of fractals in a set of positive dimension. This extends earlier results of Fishman to a more general set-up, with simpler proofs.
