description: We exhibit an infinite family of knots with isomorphic knot Heegaard Floer homology. Each knot in this infinite family admits a nontrivial genus two mutant which shares the same total dimension in both knot Floer homology and Khovanov homology. Each knot is distinguished from its genus two mutant by both knot Floer homology and Khovanov homology as bigraded groups. Additionally, for both knot Heegaard Floer homology and Khovanov homology, the genus two mutation interchanges the groups in $δ$-gradings $k$ and $-k$.

description: We consider a large neutral molecule with total nuclear charge $Z$ in a model with self-generated classical magnetic field and where the kinetic energy of the electrons is treated relativistically. To ensure stability, we assume that $Z α< 2/π$, where $α$ denotes the fine structure constant. We are interested in the ground state energy in the simultaneous limit $Z \rightarrow \infty$, $α\rightarrow 0$ such that $κ=Z α$ is fixed. The leading term in the energy asymptotics is independent of $κ$, it is given by the Thomas-Fermi energy of order $Z^{7/3}$ and it is unchanged by including the self-generated magnetic field. We prove the first correction term to this energy, the so-called Scott correction of the form $S(αZ) Z^2$. The current paper extends the result of \cite{SSS} on the Scott correction for relativistic molecules to include a self-generated magnetic field. Furthermore, we show that the corresponding Scott correction function $S$, first identified in \cite{SSS}, is unchanged by including a magnetic field. We also prove new Lieb-Thirring inequalities for the relativistic kinetic energy with magnetic fields.

The exact tail asymptotics behaviour of the joint stationary distributions of the generalized join the shortest queueing model
Creators: name: Zafari, Zafar
Publisher: name: University of British Columbia
Year: 2012

description: Parallel queueing networks have advantage over single server queueing networks, because when some servers simultaneously serve the customers in the line, the efficiency increases. Therefore, in the real world parallel queueing servers such as computer networks and multiple parallel processors, have become common. Since then many scientists have been studying the analysis of parallel queueing networks to give the exact practical models for the real world queueing problems. One of the topics in parallel queueing networks is the two-dimensional random walk, which recently have been studied by many scientists. The formulation for a random walk model in the first quadrant has been already studied by Fayolle, Malyshev and Iasnogorodski [19]. In this thesis I extend the formulation of a general random walk model to the half plane, including the first and fourth quadrants, and by using kernel method and Tauberian-like Theorem I investigate the exact tail asymptotic behaviour of the joint stationary distribution of the generating functions. In addition, I apply the results of the formulation of a general random walk model in the half plane to the Generalized-JSQ model, which is a queueing system with two parallel servers that have three streams of arrivals, two of which are dedicated to each servers, and the third one joins the shorter queue. Suppose that arrivals are independent Poisson processes, and service times have identical exponential distributions. Although this queueing model has been already studied by Zhao and Grassmann [75], and M. Miyazawa, [56], in this thesis I will use a different method named kernel method to investigate the exact tail asymptotic behaviour of the generating functions. The kernel method is simpler and faster than other methods, since in this method we are not dealing with the explicit expressions in terms of generating functions, but we only discuss the dominant singularity and its location.

description: Knotty structures of Herbig-Haro jets are common phenomena, and knowing the origin of these structures is essential for understanding the processes of jet formation. Basically, there are two theoretical approaches: different types of instabilities in stationary flow, and velocity variations in the flow. We investigate the structures with different radial velocities in the knots of the HL Tau jet as well as its unusual behaviour starting from 20 arcsec from the source. Collation of radial velocity data with proper motion measurements of emission structures in the jet of HL Tau makes it possible to understand the origin of these structures and decide on the mechanism for the formation of the knotty structures in Herbig-Haro flows. We present observations obtained with a 6 m telescope (Russia) using the SCORPIO camera with scanning Fabry-Perot interferometer. Two epochs of the observations of the HL/XZ Tau region in Halpha emission (2001 and 2007) allowed us to measure proper motions for high and low radial velocity structures. The structures with low and high radial velocities in the HL Tau jet show the same proper motion. The point where the HL Tau jet bents to the north (it coincides with the trailing edge of so-called knot A) is stationary, i.e. does not have any perceptible proper motion and is visible in Halpha emission only. We conclude that the high- and low- velocity structures in the HL Tau jet represent bow-shocks and Mach disks in the internal working surfaces of episodic outflows. The bend of the jet and the brightness increase starting some distance from the source coincides with the observed stationary deflecting shock. The increase of relative surface brightness of bow-shocks could be the result of the abrupt change of the physical conditions of the ambient medium as well as the interaction of a highly collimated flow and the side wind from XZ Tau.

description: A Zeeman-insensitive optical clock atomic transition is engineered when nuclear spins are dressed by a non resonant radio-frequency field. For fermionic species as $^{87}$Sr, $^{171}$Yb, and $^{199}$Hg, particular ratios between the radiofrequency driving amplitude and frequency lead to "magic" magnetic values where a net cancelation of the Zeeman clock shift and a complete reduction of first order magnetic variations are produced within a relative uncertainty below the $10^{-18}$ level. An Autler-Townes continued fraction describing a semi-classical radio-frequency dressed spin is numerically computed and compared to an analytical quantum description including higher order magnetic field corrections to the dressed energies.

The methods we describe are practical in the case n=3 for elliptic curves over the rationals, and have been implemented in Magma. One important ingredient of our work is an algorithm for trivialising central simple algebras. This is of independent interest: for example, it could be used for parametrising Brauer-Severi surfaces.

description: We obtain Dini conditions with "exponent 2" that guarantee that an asymptotically conformal quasisphere is rectifiable. In particular, we show that for any e>0 integrability of (esssup_{1-t < |x| < 1+t} K_f(x)-1)^{2-e} dt/t implies that the image of the unit sphere under a global quasiconformal homeomorphism f is rectifiable. We also establish estimates for the weak quasisymmetry constant of a global K-quasiconformal map in neighborhoods with maximal dilatation close to 1.

description: In Alberta, synthetic crude oil is produced from the oil sands. After oil extraction from the oil sands generated waste is dumped into the tailings ponds. It has been studied that the tailings ponds have an affinity to release carbon dioxide and methane into the environment due to the microbial biodegradation/fermentation of lost diluent. Currently, not enough studies have been done to reuse the oil sands tailings waste. This study introduces the treatment of tailings solvent recovery unit (TSRU) tailings waste. It is generated during the oil sands treatment process. In this research, TSRU tailings waste is converted into the activated carbon-zeolite (ACZ) composite. In this thesis two different methods used for the synthetization of the ACZ composite. Where, two-step method (activation followed by hydrothermal synthetization) and fusion-assisted methods have been studied in this report. TSRU tailings waste contains quartz and several heavy metals which are removed by the fusion treatment before the activation. Brunauer-Emmett-Teller (BET) result showed that the fused sample had 236 m2/g of surface area, whereas the non-fused sample had 108 m2/g of surface area. The resulting composite, with the addition of potassium hydroxide for enhanced porosity, demonstrated a notable surface area of 430 m2/g. The increase in the surface area also showed an increase in the overall CO2 capture capacity. The utilization of the TSRU tailings for the synthetization of ACZ composite eliminates the source of greenhouse gas (GHG) emissions, and the composite can be used for CO2 uptake. By converting TSRU tailings waste into valuable ACZ composites, the study not only addresses environmental concerns associated with tailings ponds but also presents a viable solution for carbon capture. The findings of this research have the potential to pave the way for a more sustainable and environmentally friendly approach to managing oil sands waste.

description: It is well-known that a nilpotent n by n matrix B is determined up to conjugacy by a partition of n formed by the sizes of the Jordan blocks of B. We call this partition the Jordan type of B. We obtain partial results on the following problem: for any partition P of n describe the type Q(P) of a generic nilpotent matrix commuting with a given nilpotent matrix of type P. A conjectural description for Q(P) was given by P. Oblak and restated by L. Khatami. In this paper we prove "half" of this conjecture by showing that this conjectural type is less than or equal to Q(P) in the dominance order on partitions.

Electric charge in the field of a magnetic event in three-dimensional spacetime

Year: 2011
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We analyze the motion of an electric charge in the field of a magnetically charged event in three-dimensional spacetime. We start by exhibiting a first integral of the equations of motion in terms of the three conserved components of the spacetime angular momentum, and then proceed numerically. After crossing the light cone of the event, an electric charge initially at rest starts rotating and slowing down. There are two lengths appearing in the problem: (i) the characteristic length $\frac{q g}{2 πm}$, where $q$ and $m$ are the electric charge and mass of the particle, and $g$ is the magnetic charge of the event; and (ii) the spacetime impact parameter $r_0$. For $r_0 \gg \frac{q g}{2 πm}$, after a time of order $r_0$, the particle makes sharply a quarter of a turn and comes to rest at the same spatial position at which the event happened in the past. This jump is the main signature of the presence of the magnetic event as felt by an electric charge. A derivation of the expression for the angular momentum that uses Noether's theorem in the magnetic representation is given in the Appendix.

description: Emissions trading systems (ETS) have been a widely-adopted policy instrument for global climate mitigation and a key choice in China’s pledge for peaking emissions and carbon neutrality. Broader adoption and linkage of ETS programmes require a better understanding of whether, to what extent, and how existing regional programmes address carbon emissions at an aggregate level. Combining a synthetic control method and event studies, we adopt a comprehensive evaluation framework to investigate regional mitigation effects, pathways, and ancillary impacts in three Chinese regions with four independent pilot ETS programmes. The findings show economy-wide responses to pilot announcement even in non-ETS sectors, but enduring mitigation only within ETS sectors. Mitigation was achieved via improvement in energy efficiency and fuel switch, without impairing industrial activities. There were local air-pollution reduction co-benefits but no leakage or spillover. Bounded extrapolation from the pilots suggests 18%–20% reductions can be achieved in non-pilot regions by a national market, which could learn from pilots’ experiences to broaden sector coverage and ensure policy consistency and transparency. Regional ETS were able to stabilize emissions with little cost, providing rationale for rapidly developing economies to adopt such systems. Key policy insightsDespite being unlinked, regional ETS pilots delivered substantial climate mitigation and local air pollution reduction in China.Policy effects were initially driven by economy-wide mitigation due to policy expectations, followed by ETS-sector mitigation due to carbon pricing.Industries reduced CO2 emissions from energy efficiency improvements and fuel switch.Mitigation was accompanied by little emission leakage or impairment to the economy.Extrapolating mitigation rates in a national market suggests 18%–20% reduction of CO2.

description: A major challenge in biology is determining what governs the precise spatiotemporal gene expression required to pattern the vertebrate embryo. As vertebrate genomes continue to be sequenced, the presence of large, noncoding regions of DNA termed gene deserts are found with prominence. Complete with the information that they are often highly conserved and located near important developmental genes (such as the short stature homeobox 2 gene; Shox2), gene deserts have become a focus for their potential in cis-regulatory governance. The work in this thesis partially uncovers the regulatory mechanism of Shox2; a gene with pleiotropic developmental functions in mice located upstream of a 675 kb gene desert (S2GD) with cis-regulatory sequences that have activity in the limb and brain of transgenic mice. Our findings show that Shox2 expression in the mouse limb and brain partially requires the presence of the S2GD. More specifically, following a removal of the majority of the S2GD (582 kb) and a sensitized genetic background for Shox2 in the limb (whereby all Shox2 expression in the limb comes from the allele lacking the majority of the S2GD), mice display abnormal proximal limb formation that proceeds into adulthood. Second, when mice are bred on a sensitized genetic background for Shox2 in the central nervous system (CNS) (this time with all Shox2 expression in the CNS coming from the allele lacking the majority of the S2GD), mice not only display aberrant exploratory behaviour and motor coordination in both sexes, but reduced Shox2 expression in E12.5 hindbrain nuclei (n=3) and an overexpression of Shox2 in P1 pontine nuclei (n=2). Ultimately, the work in this thesis provides a paradigm for the regulation of an important developmental gene in mice, brought forth in part by the downstream gene desert.

description: The accreting X-ray pulsar Her X-1 shows two types of long-term variations, both with a period of 35 days: 1) A modulation of the flux with a ten day long Main-On and a 5 d long Short-On, separated by two Off-states, and 2) A systematic variation of the shape of the 1.24 s pulse profile. While there is general consensus that the flux modulation is due to variable shading of the X-ray emitting regions on the surface of the neutron star by the precessing accretion disk, the physical reason for the variation of the pulse profiles had remained controversial. Following the suggestion by Truemper et al. (1986) that free precession of the neutron star may be responsible for the variation of the pulse profiles, we had developed physical models of strong feedback interaction between the neutron star and the accretion disk in order to explain the seemingly identical values for the periods of the two types of variations. In a deep analysis of pulse profiles observed by several different satellites over the last three decades we find now that the clock behind the pulse profile variations shows exactly the same erratic behavior as the turn-on clock, even on short time scales (100 d), suggesting that there may in fact be only one 35 d clock in the system. If this is true, it presents a serious challenge for the idea of free precession of the neutron star and calls for alternative physical models for the variation in pulse shape.

description: Chatbots are “computer agents that can interact with the user” in a way that feels like human-to- human conversation.1 While the use of chatbots for reference service in academic libraries is a topic of interest for both library professionals and researchers, little is known about how they are used in library reference service, especially in academic libraries in Canada. This article aims to fill this gap by conducting a web-based survey of 106 academic library websites in Canada and analyzing the prevalence and characteristics of chatbot and live chat services offered by these libraries. The authors found that only two libraries were using chatbots for reference service. For live chat services, the authors found that 78 libraries provided this service. The article discusses possible reasons for the low adoption of chatbots in academic libraries, such as accessibility, privacy, cost, and professional identity issues. The article also provides a case study of the authors’ institution, the University of Calgary, which integrated a chatbot service in 2021. The article concludes with suggestions for future research on chatbot use in libraries.

description: International students from around the world are increasingly being recruited and admitted to secondary schools and universities across Canada. As neither immigrants nor native-born Canadians, international students occupy a special space in the student landscape and have significantly different identities than other groups of culturally and linguistically diverse students. The unique experiences and perspectives of adolescent international students in Canadian secondary schools requires further study as this area has been largely overlooked in the literature. This exploratory study investigated the experiences of international students in a Canadian secondary school through semi-structured interviews with three students, one from Korea and two from Japan. Prior to the interviews, students were given the interview questions in the form of a questionnaire translated into their first language and asked to reflect on and respond to the questions in writing. Students were asked to share their perspectives on the educational and cultural differences between the school(s) they attended in their home country and their school in Canada. The interview transcripts and written responses revealed reoccurring themes corresponding to the key words or ideas within each reply. The students in this study were very positive in their perception of the Canadian education system and unanimously agreed that they preferred studying in Canada over studying in their home countries. The cultural differences discussed in the interviews were perceived as positive and beneficial rather than problematic. The social differences between Canada and their home countries, in terms of how they were allowed to interact with others and how others, especially their teachers, responded to them, were found to be the most important and meaningful differences for all three students. These social differences included having more personal autonomy and freedom, both in and out of the classroom, having positive and “comfortable” relationships with teachers and the student-centered nature of Canadian teaching methods. Environmental differences, such as the school schedule and student course load, were also mentioned several times. Strictly instructional differences, in terms of types of class activities and assignments, were only discussed when I asked about them directly.

description: The spinel FeV2O4 is known to exhibit peculiar physical properties, which is generally ascribed to the unusual presence of two cations showing a pronounced interplay between spin, orbital and lattice degrees of freedom (Fe2+ and V3+ on the tetrahedral and octahedral sites, respectively). The present work reports on an experimental re-investigation of this material based on a broad combination of techniques, including x-ray diffraction, energy dispersive and Mössbauer spectroscopies, as well as magnetization, heat capacity, dielectric and polarization measurements. Special attention was firstly paid to establish the exact cationic composition of the investigated samples, which was found to be Fe1.18V1.82O4. All the physical properties were found to point out a complex ordering process with a structural transition at TS = 138 K, followed by two successive magnetostructural transitions at TN1 = 111 K and TN2 = 56 K. This latter transition marking the appearance of electric polarization, magnetization data were analysed in details to discuss the nature of the magnetic state at T< TN2. An overall interpretation of the sequence of transitions was proposed, taking into account two spin couplings, as well as the Jahn-Teller effects and the mechanism of spin-orbit stabilization. Finally, the origin of ferroelectricity in Fe1.18V1.82O4 is discussed on the basis of recent models.

description: Essential genes are deemed crucial for survival and/or reproductive success, hence, their loss of function leads to lethality. However, gene essentiality is not static, but dependent on multiple factors, including the genetic background. The genetic background affects gene essentiality through genetic modifiers, second-site variants capable of interacting with the primary variant and altering phenotype. Genetic modifiers can act as suppressors, alleviating the phenotype, or enhancers, exacerbating the phenotype. The plasticity (modification) of gene essentiality caused by genetic modifiers has been shown in multiple species. In Caenorhabditis elegans, recent evidence shows phenotypic variability for knock-down of essential genes in two natural isolates: N2 and CB4856. N2 represents the laboratory-cultivated strain, while CB4856 is one of the strains with most diverse genome in comparison to N2. Much has been explored for these two genetic backgrounds, but little is known about the plasticity of gene essentiality in other C. elegans wild isolates. Thus, I here explore the effect of the genetic background on the plasticity of two genes, known as essential in the N2 background, but potentially dispensable in CB4856: the Metaphase-to-Anaphase Transition Defect gene (mat-1), and the Conserved Germline Helicase (cgh-1). These are involved in cell division and posttranscriptional regulation, respectively. Here, I further investigate the plasticity of mat-1 and cgh-1 in N2 and CB4856 backgrounds, and also include four other wild isolate backgrounds from diverse geographical locations (GXW1, KR314, JU1400, and AB1). Using hatch rate and propagation assays, I explored the phenotype of mat-1 and cgh-1 knockdowns across the six natural isolates using temperature-sensitive alleles and uncovered phenotypic variability for the embryonic lethal phenotype, suggestively due to influence of each genetic background. Next, bioinformatics and genomics tools were utilized for identification of candidate genetic modifiers for mat-1 and cgh-1 and led to prioritization of eight extragenic variants. Out of these, none showed notable modifying activity when studied in isolation. Importantly, this work shows the challenges associated with identifying true genetic modifiers in genomes with substantial variation. Undeniably, understanding more about a gene and its phenotype under different conditions and genetic backgrounds may be fundamental for elucidating fixed and plastic genetic interactions.

description: Mass Media hold great power in shaping public opinion and they function as an informative mediation tool between societies. Gender-based violence and femicide are harmful acts, originating from socially ascribed gender roles, that are being also perpetuated by Media, only with variant cultural hues. The representation of these social problems in Social Media platforms, such as Twitter, taking the shape of online movements, can provoke radical socio-economic and political changes, and equally extreme reactions. This diplomatic thesis’s investigation focuses on eight selected cases of influential Twitter movements on a global scale, that are being examined from a cultural, semantic, and legal perspective, in order to highlight the relations between cultures and how they are being accentuated by Media to the public. This analysis’s aim is to conclude to what exact extent is the influence of Twitter shaping the new social reality and the fourth feminist wave. Compatibility and divergences between cultures are discussed, as well as further research, that is considered vital for sustainable solutions and future social change.
description: Τα Μέσα Μαζικής Ενημέρωσης έχουν τη δύναμη να διαμορφώνουν τη κοινή γνώμη μέσα στην εκάστοτε κοινωνία, καθώς λειτουργούν ως ενημερωτικά εργαλεία διαμεσολάβησης. Η έμφυλη βία και η γυναικοκτονία αποτελούν βλαβερές πράξεις και προέρχονται από κοινωνικά επιρριπτόμενους φυλετικούς ρόλους με ποικίλες πολιτισμικές αποχρώσεις, που αναπαράγονται μονοδιάστατα από τα Μέσα. Η προβολή αυτών των κοινωνικών προβλημάτων σε πλατφόρμες Κοινωνικής Δικτύωσης, όπως το Twitter, λαμβάνουν τη μορφή διαδικτυακών κινημάτων και μπορούν να επιφέρουν ριζικές κοινωνικές, οικονομικές και πολιτικές αλλαγές, καθώς και εξίσου ακραίες αντιδράσεις. Η έρευνα αυτής της διπλωματικής εργασίας επικεντρώνεται σε οκτώ επιλεγμένες περιπτώσεις σημαινόντων κινημάτων του Twitter παγκόσμιας κλίμακας, οι οποίες εξετάζονται από πολιτισμική, σημασιολογική και νομική οπτική, ώστε να επισημανθεί το πως αναπαρίσταται η σχέση μεταξύ των πολιτισμών από τα Μέσα στο κοινό. Ο σκοπός αυτής της ανάλυσης είναι η σκιαγράφηση του πραγματικού εύρους επιρροής του Twitter, το οποίο διαμορφώνει την καινούργια κοινωνική πραγματικότητα καθώς και το τέταρτο φεμινιστικό κύμα. Λόγος γίνεται για τη συμβατότητα και τις αποκλίσεις μεταξύ πολιτισμών, ενώ περαιτέρω έρευνα κρίνεται ζωτική για την εύρεση βιώσιμων λύσεων και την επιτέλεση της όποιας κοινωνικής αλλαγής στο μέλλον.

description: Effects of doping on morphology of iron carbide (cementite) nanowires have been explored by first principle electronic structure calculations. We examined the role of several realistic impurities (Si, Mn, V, P and S) in the formation energies of the cementite nanowires with different sizes and morphologies. It is shown that the presence of the impurities decreases the formation energy and can switch the preferable axis of the cementite nanowire growth. The conditions of the formation and decomposition of cementite nanowires in steels are also discussed.
