description: We have studied a quinary Fe-based superconductor Sr$_2$VFeAsO$_3$ by the measurements of x-ray diffraction, x-ray absorption, Mössbauer spectrum, resistivity, magnetization and specific heat. This apparently undoped oxyarsenide is shown to be self doped via electron transfer from the V$^{3+}$ ions. We observed successive magnetic transitions within the VO$_2$ layers: an antiferromagnetic transition at 150 K followed by a weak ferromagnetic transition at 55 K. The spin orderings within the VO$_2$ planes are discussed based on mixed valence of V$^{3+}$ and V$^{4+}$.

description: A recently proposed SO(5)xU(1) gauge-Higgs unification model in the Randall-Sundrum warped space contains a very interesting dark matter candidate, the Higgs boson. As a part of the fifth component of a five-dimensional gauge field, the four-dimensional neutral Higgs boson has odd H parity while all the other standard model particles have even parity to all orders in perturbation theory. Based on H-parity conserving WWHH and ZZHH vertices, we investigate the collider signatures of Higgs dark matter production associated with a SM W or Z gauge boson at the LHC and the ILC. The final state consists of a W or a Z boson with large missing energy. We found that the level of the signal cross section is quite hopeless at the LHC while we may be able to identify it at the ILC with polarized electron beams.

description: Twenty-one samples belonging to species of Spyridia Harvey with uncinate (= hook-shaped) spines on determinate lateral branches were investigated for their morphology with a focus on the structure of determinate branches, and for comparative chloroplast-encoded rbcL and nuclear LSU rDNA sequence analysis to elucidate their taxonomy and phylogeny. Currently, four Spyridia species with uncinate spines are recognized worldwide: S. alternans, S. cupressina, S. horridula and S. hypnoides. Of them, S. hypnoides has been recognized as the most common species with uncinate spines. In this study, we show that S. aculeata needs to be resurrected from S. hypnoides, and recognized as a distinct species based on samples from Israel, Red Sea, near the type locality. Spyridia aculeata is characterized by the spiral arrangement of determinate branches, incompletely corticated determinate branches, naked basal segment of determinate branches, by the presence of only acropetal cortication in the nodes of determinate branches, and by uncinate spines at the terminal node and on the first and second nodes of determinate branches. In our molecular analyses based on rbcL and LSU rDNA, although four Spyridia species with uncinate spines are supported on phylogenetic trees, they are not a monophyletic group. The feature of uncinate spines in Spyridia is recognized as a polyphyletic character. Our phylogenetic analysis using rbcL and LSU rDNA sequences reveals high gene sequence divergence (6.8–7.0% for rbcL and 1.2–1.3% for LSU rDNA) between samples of S. aculeata and S. hypnoides. Therefore, the distribution of S. hypnoides may be restricted to the Indian Ocean, whereas S. aculeata is widely distributed in the Atlantic Ocean including the Mediterranean Sea and the Red Sea. Another Spyridia species with uncinate spines, S. alternans, is recognized as a synonym of S. horridula by our detailed morphological observations of its type specimen.
School mergers in Singapore: a sociological analysis of educational equity

Publisher: name: Monash University
Year: 2023
Subjects: Sociology of education

description: This thesis is written to address, in part, the issue of just who enjoys access to which school, and the differing experiences and outcomes of graduates from different schools in Singapore. I problematise the issue of school closures in Singapore beyond the official narrative of slowing population growth. Questions of social justice in Singapore about state education’s contribution to social mobility and the reproduction of social inequality have been raised in recent years. I argue that Singapore schools have been moulded by the state’s ideological bearings of meritocracy and elitism, thus resulting in its current hierarchical form. My thesis brings to the fore issues of social mobility, equality and equity as manifested through public education and school choice and contributes to the extant literature on the sociology of education.
A geometric approach to correlations and quark number susceptibilities

description: We study the thermodynamic geometry arising from the free energy for the 2- and 3-flavor finite temperature hot QCD near the critical temperature. We develop a geometric notion for QCD thermodynamics, relating it with the existing microscopic quantities, e.g. quark-number susceptibility, which appears naturally within an approximately self-consistent resummation of perturbative QCD. We further incorporate thermal fluctuations in the free energy, thus yielding the geometric properties of local and global chemical correlations. These investigations are perturbative in nature. Nevertheless, one could apply the same line of thought for the geometric realization of underlying quark susceptibilities, either in the fabric of lattice QCD or in that of non-perturbative QCD.

Subjects: Screen media

description: This thesis explores how television criticism has recently been reimagined from what was once a small section within print broadsheet newspapers to become a dynamic, central component of television post-viewing engagement practices. Through an examination of three case studies—the recap, the thinkpiece, and the podcast—this thesis brings journalistic critical perspectives on television to the fore, employing the critic as a lens through which to assess changes to the contemporary television landscape.

description: Algal turfs are ecosystem engineers receiving steadily growing attention in recent years in relation to their expansion on temperate reefs due to global change. However, their species diversity and taxonomy are still poorly understood, mostly based solely on morphological information. Algal turfs are the dominant type of assemblage in Macaronesia, but molecular diversity surveys have barely been applied in this region. We aim to show how molecular tools can assist us to improve our understanding of the diversity and taxonomy of natural algal turfs by studying the turf-forming rhodomelacean genus Stichothamnion which has only one recognized species in Macaronesia, the generitype S. cymatophilum. Stichothamnion resembles other members of the tribe Streblocladieae, but it has unbranched trichoblasts, an unusual character in the family. Here, we show using phylogenetic analyses of the rbcL gene that specimens collected in the Canary Islands and the Azores identifiable morphologically as S. cymatophilum exhibit cryptic diversity, and these analyses position Stichothamnion in the Vertebrata clade with full support. We place Stichothamnion in synonymy with Vertebrata, transfer the existing species, and describe a newly discovered cryptic species as V. barbarae Muñoz-Luque & Díaz-Tapia, sp. nov., found exclusively in the Azores. The new species was morphologically indistinguishable from V. cymatophila but diverged by 2.1–2.3% in the rbcL gene. This study illustrates the work required to better understand the extraordinary species diversity in algal turfs such as those in Macaronesia which remain taxonomically under-studied.

description: Four different neutrino mass sum-rules have been analyzed: these frequently arise in flavor symmetry models based on the groups A_4, S_4 or T', which are often constructed to generate tri-bimaximal mixing. In general, neutrino mass can be probed in three different ways, using beta decay, neutrino-less double beta decay and cosmology. The general relations between the corresponding three neutrino mass observables are well known. The sum-rules lead to relations between the observables that are different from the general case and therefore only certain regions in parameter space are allowed. Plots of the neutrino mass observables are given for the sum-rules, and analytical expressions for the observables are provided. The case of deviations from the exact sum-rules is also discussed, which can introduce new features. The sum-rules could be used to distinguish some of the many models in the literature, which all lead to the same neutrino oscillation results.

description: This thesis charts a genealogy for the critical essay, a topical subset of the literary essay that includes analysis of an artwork amongst its objects of inquiry. After examining the genre’s literary, theoretical and philosophical antecedents, the critical essay is deployed as an analytical framework through which to read the work of contemporary North American practitioners Wayne Koestenbaum, Chris Kraus and Hilton Als. The critical essay is then applied as a creative methodology in an accompanying creative project, Terror Australis, a suite of seven interlinked critical essays examining representations of fear in Australian cinema.

description: We have performed Raman-scattering measurements on a high-quality single crystal of the recently discovered Fe-based superconductor K$_{0.8}$Fe$_{1.6}$Se$_2$ ($T_c$ = 32 K). At least thirteen phonon modes were observed in the wave number range 10$-$300 cm$^{-1}$. The spectra possess a four-fold symmetry indicative of bulk vacancy order in the Fe-deficient planes. We perform a vibration analysis based on first-principles calculations, which both confirms the ordered structure and allows a complete mode assignment. We observe an anomaly at $T_c$ in the 180 cm$^{-1}$ $A_g$ mode, which indicates a rather specific type of electron-phonon coupling.

description: We consider large-scale collective motion of flat edge-on spiral galaxies from the Revised Flat Galaxy Catalogue (RFGC) taking into account the curvature of space-time in the Local Universe at the scale 100 Mpc/h. We analyse how the relativistic model of collective motion should be modified to provide the best possible values of parameters, the effects that impact these parameters and ways to mitigate them. Evolution of galactic diameters, selection effects, and difference between isophotal and angular diameter distances are inadequate to explain this impact. At the same time, measurement error in HI line widths and angular diameters can easily provide such an impact. This is illustrated in a toy model, which allows analytical consideration, and then in the full model using Monte Carlo simulations. The resulting velocity field is very close to that provided by the non-relativistic model of motion. The obtained bulk flow velocity is consistent with ΛCDM cosmology.

Generalized mechanics and dynamics of 3-axis machining processes
Creators: name: Dabiri Farahani, Nima
Publisher: name: University of British Columbia
Year: 2021

description: Machining processes are widely used to achieve the net shape of the parts in the industry. To plan the process with desired productivity and accuracy, the mechanics and dynamics of machining operations must be modeled to predict the cutting forces, torque, power of the spindle, and deflection marks left on the cut surface. Namely milling, drilling, boring, and turning, all machining processes remove layers of the workpiece to achieve the final product. Due to the similarities between different machining operations in terms of the cutting principles, they are generalized in one mathematical model to predict the cutting mechanics and dynamics in this thesis. Although operations are varied in terms of tool setup and configurations, all the tools are modeled through basic CAD elements and combined to achieve the final tool assembly. Considering the tool and workpiece's relative translational and rotational motions, the process types are determined automatically, and cutting engagement angles in the contact zone are interpreted from the tool CAD model, addressing all the geometrical features. A unified kinematics model is proposed to predict the cutting forces, spindle torque, and deflection marks left on the cut surface. The process kinematics are also used for a fast and acceptably accurate prediction of the chatter stability in the frequency domain. The results of the developed generalized physics-based model are presented for multiple industrial applications, including milling, drilling, boring, and turning operations. The simulated cutting mechanics and chatter stability charts predicted by the analytical model are demonstrated to be valid through comparisons with experimental measurements and existing data available in the literature. The proposed generalized model allows the planners to predict and optimize the 3-axis machining operations by avoiding costly trial and error-based tests in the industry.

Connections between the Seesaw and Dark Matter Searches

description: In some dark matter models, the coupling of the dark matter particle to the standard model Higgs determines the dark matter relic density while it is also consistent with dark matter direct detection experiments. On the other hand, the seesaw for generating the neutrino masses probably arises from a spontaneous symmetry breaking of global lepton number. The dark matter particle thus can significantly annihilate into massless Majorons when the lepton number breaking scale and hence the seesaw scale is near the electroweak scale. This leads to an interesting interplay between neutrino physics and dark matter physics and the annihilation mode has an interesting implication on dark matter searches.

description: Populations within the same species range edge may experience contrasting local conditions and exhibit diverse levels of environmental tolerance. This heterogeneity within a range boundary has seldom been considered in studies forecasting the impact of anthropogenic habitat alteration and climate change on species distributions. Moreover, any ecological prediction under changing environmental conditions requires a good understanding of the combined responses of organisms to multiple stressors, in particular the effects on key life cycle stages of species. The intertidal seaweed Fucus serratus is a dominant species on northern Atlantic shores and whose southern limit is in the NW Iberian Peninsula. We examined how early developmental stages of southern-edge populations of this foundation alga responded to the combined effects of environmental stressors, including salinity and aerial and seawater temperature. Four populations from two different areas of the NW Iberian coast were considered: two populations from open shores on the northern coast and two populations from the western rias on the Atlantic coast. The study findings revealed inter-population variability in the response to heat stress, with greater survival of germlings from the northern populations than those from western rias. Environmental conditions are still more benign within western rias, under the influence of strong summer upwelling events. The results also suggest the key role of aerial thermal stress in determining the southern limit of distribution of the target species. The future of these heterogeneous edge populations from NW Iberian Peninsula depends on trends in climate change and the ability of populations to cope with these. Environmental changes may already be occurring at rates that exceed the plastic and adaptive potential of edge populations in N Spain, while the future of western rias as climate refugia for this and other foundation alga is also uncertain.
The Quantum Hall Effect in Graphene

description: We investigate the quantum Hall effect in graphene. We argue that in graphene in presence of an external magnetic field there is dynamical generation of mass by a rearrangement of the Dirac sea. We show that the mechanism breaks the lattice valley degeneracy only for the $n=0$ Landau levels and leads to the new observed $ν= \pm 1$ quantum Hall plateaus. We suggest that our result can be tested by means of numerical simulations of planar Quantum Electro Dynamics with dynamical fermions in an external magnetic fields on the lattice.

Integration of sea surface temperature and light for prediction of coral bleaching
Creators: name: González Espinosa, Pedro Cuautémoc
Publisher: name: University of British Columbia
Year: 2021

description: Climate change represents one of the principal threats to coral reef ecosystems because of an increase in mass coral bleaching and associated coral mortality due to more frequent and severe thermal stress. Even though most research has focused on temperature, coral bleaching results from the interacting effects of temperature and other environmental variables such as solar radiation. Exposure of corals to high light exacerbates the impact of thermal stress on corals, whereas reductions in light can reduce sensitivity to thermal stress. This dissertation aims to integrate the effects of light and temperature to assess how corals have responded to periods of cold and warm water, and under various future climate change scenarios. The synergetic effect of light is evaluated through the development of different models and methods. First, performing a logistic regression model approach on cold-water bleaching observations I find that cold-water bleaching can be best predicted with an accumulated cold-temperature metric (Degree Cooling Weeks), although the effect of light marginally improved prediction accuracy. Second, using mixed-effects models on a global database of warm-water bleaching observations and environmental metrics, I find that coral reefs exposed to severe bleaching-level heat stress show a reduced bleaching response if exposed to high cloudiness. Then, I developed a ‘cloudy refugia’ index which identifies regions where cloudiness is most likely to protect corals from bleaching. The findings suggest that incorporating cloudiness into prediction models can help identify reefs that may be more resilient to climate change. Finally, using mixed-effects models on future climate projections from GFDL-ESM4, I find that though warming ocean water is the primary driver of future coral bleaching conditions, cloudiness might delay the onset of frequent bleaching by four decades in low emission scenarios. However, the protection of clouds in addition to corals' ability to adapt to climate conditions are likely to be outpaced in high-emission scenarios. This research provides an overarching assessment of the influence of thermal stress and light on mass coral bleaching patterns globally. Furthermore, it demonstrates the value of including more driving variables when examining the fate of coral reefs in different future greenhouse gas emissions scenarios.
Complicating the “Yellow Peril”: Chinese Responses to Early Twentieth-century British Literary Representations of China

description: The Yellow Peril is understood generally as a racist discourse that degrades Easterners, especially the Chinese. But the crucial reactions to Yellow Peril from Chinese writers, the three British writers (Goldsworthy Lowes Dickinson, Sax Rohmer, and William Somerset Maugham), and the Chinese readers of the three British writers’ works I study suggest a strategic and instrumental response that attempts to exploit the Yellow Peril and its associated ideas to defend or advance personal and national interests (British or Chinese). This duo-foci study not only contributes to literary-historical research but to China–West studies more broadly.

description: Global climate change has profound effects on species distributions, causing range shifts and population extinctions. Range-edge populations that are better adapted or acclimatized to stressful environments than core populations may ensure the persistence of species under future climate conditions, especially in environments at the retreating, rear edge of distributions. Furthermore, geographically peripheral populations are not always located in unfavourable sites, as they can occupy suitable environments. We examined how early developmental stages of rear-edge populations of the foundation alga Fucus serratus responded to the combined effects of environmental factors, including salinity and aerial and seawater temperature. Four populations from two different areas of the NW Iberian coast were considered: two populations from open shores on the northern Cantabrian coast (province of Lugo) and two populations from the western rias on the Atlantic coast. The study findings confirmed differential heat resistance in early developmental stages of the alga in populations at the trailing edge. The results also highlighted the strong influence of aerial thermal stress, either alone or in synergy with seawater temperature, on the performance of early stages of F. serratus. The findings thus suggest that aerial thermal stress plays a key role in determining the southern limits of distribution. Regardless of the underlying mechanisms that drive such intraspecific variability in rear-edge populations, differential responses may be important for the persistence of canopy-forming species. Nevertheless, the future of these two distinct groups of marginal populations remains an open question with important ecological and evolutionary implications.

description: It is known that strong electric fields produce electron and positron pairs from the vacuum, and due to the back-reaction these pairs oscillate back and forth coherently with the alternating electric fields in time. We study this phenomenon in spatially inhomogeneous and bound electric fields by integrating the equations of energymomentum and particle-number conservations and Maxwell equations. The space and time evolutions of the pair-induced electric field, electric charge- and currentdensities are calculated. The results show that non-vanishing electric charge-density and the propagation of pair-induced electric fields, differently from the case of homogeneous and unbound electric fields. The space and time variations of pair-induced electric charges and currents emit an electromagnetic radiation. We obtain the narrow spectrum and intensity of this radiation, whose peak ωpeak locates in the region around 4 KeV for electric field strength \sim Ec. We discuss their relevances to both the laboratory experiments for electron and positron pair-productions and the astrophysical observations of compact stars with an electromagnetic structure.

description: Binary systems of compact objects with electromagnetic field are modeled by helically symmetric Einstein-Maxwell spacetimes with charged and magnetized perfect fluids. Previously derived thermodynamic laws for helically-symmetric perfect-fluid spacetimes are extended to include the electromagnetic fields, and electric currents and charges; the first law is written as a relation between the change in the asymptotic Noether charge $\dl Q$ and the changes in the area and electric charge of black holes, and in the vorticity, baryon rest mass, entropy, charge and magnetic flux of the magnetized fluid. Using the conservation laws of the circulation of magnetized flow found by Bekenstein and Oron for the ideal magnetohydrodynamic (MHD) fluid, and also for the flow with zero conducting current, we show that, for nearby equilibria that conserve the quantities mentioned above, the relation $\dl Q=0$ is satisfied. We also discuss a formulation for computing numerical solutions of magnetized binary compact objects in equilibrium with emphasis on a first integral of the ideal MHD-Euler equation.

description: Stationary black holes of massless supergravity theories are described by certain geodesic curves on the target space that is obtained after dimensional reduction over time. When the target space is a symmetric coset space we make use of the group-theoretical structure to prove that the second order geodesic equations are integrable in the sense of Liouville, by explicitly constructing the correct amount of Hamiltonians in involution. This implies that the Hamilton-Jacobi formalism can be applied, which proves that all such black hole solutions, including non-extremal solutions, possess a description in terms of a (fake) superpotential. Furthermore, we improve the existing integration method by the construction of a Lax integration algorithm that integrates the second order equations in one step instead of the usual two step procedure. We illustrate this technology with a specific example.

description: Heavy quark production has been very well studied over the last years both theoretically and experimentally. Theory has been used to study heavy quark production in $e p$ collisions at HERA, in $pp$ collisions at Tevatron and at RHIC, in $pA$ and $dA$ collisions at RHIC and in $AA$ collisions at CERN-SPS and at RHIC. However, to the best of our knowledge, heavy quark production in $eA$ has received almost no attention. With the possible construction of a high energy electron-ion collider, updated estimates of heavy quark production are needed. We address the subject from the perspective of saturation physics and compute the heavy quark production cross section with the dipole model. We isolate shadowing and non-linear effects, showing their impact on the charm structure function and on the transverse momentum spectrum.

description: We report the study of high quality samples of the frustrated S = 1/2 kagome antiferromagnet vesignieite, Cu3Ba(VO5H)2. Neutron powder diffraction measurements evidence the high quality of the kagome lattice and show no sign of a transition to long-range order. A kink in the susceptibility below T = 9 K is matched to a reduction in paramagnetic-like correlations in the diffraction data and a slowing of the spin dynamics observed by MuSR. Our results point to an exotic quantum state below 9 K with coexistance of both dynamical and small frozen moments \sim 0.1 \muB. We propose that Dzyaloshinsky-Moriya interaction is large enough in this system to stabilize this novel quantum ground state.
