description: We present a general method, based on a multiple-scale approach, for deriving the perturbative solutions of the scaling equations governing the expansion of superfluid ultracold quantum gases released from elongated harmonic traps. We discuss how to treat the secular terms appearing in the usual naive expansion in the trap asymmetry parameter epsilon, and calculate the next-to-leading correction for the asymptotic aspect ratio, with significant improvement over the previous proposals.

description: In 2008, a large-scale outdoor sculpture created by world-renowned artist, Dennis Oppenheim, was installed on a proposed site for a billion dollar mixed-use real estate redevelopment project in Calgary’s historic Ramsay neighbourhood. Oppenheim’s sculpture, Device to Root out Evil is one of many public artworks recently installed in East Calgary and serves as a prime example of how public art is being integrated into urban development and private real estate projects. This research project explores how cultural artifacts, such as public art, are being used as placemaking tools. This localized case study connects artistic practice to economic emplacement and displacement, cultural consumption and production, and urban change. It is a mixed-methods ethnography that moves beyond visual analysis of public art to incorporate sensory experiences of being in a place, thereby revealing how attending to the senses can contribute to the placemaking process.

description: Using the Space Telescope Imaging Spectrograph (STIS) onboard the Hubble Space Telescope, we have obtained high-resolution ultraviolet spectra of the C I absorption toward two stars behind the Local Leo Cold Cloud (LLCC). At a distance (~20 pc) that places it well inside the Local Bubble, the LLCC is the nearest example of the coldest known (T~20 K) diffuse interstellar clouds. The STIS measurements of the C I fine-structure excitation toward HD 85259 and HD 83023 indicate that the thermal gas pressure of the LLCC is much greater than that of the warm clouds in the Local Bubble. The mean LLCC pressure measured toward these two stars (60,000 cm$^{-3}$ K) implies an H I density of ~3000 cm$^{-3}$ and a cloud thickness of ~200 AU at the 20 K cloud temperature. Such a thin, cold, dense structure could arise at the collision interface between converging flows of warm gas. However, the measured LLCC pressure is appreciably higher than that expected in the colliding cloud interpretation given the velocity and column density constraints on warm clouds in the HD 85259 and HD 83023 sightlines. Additional STIS measurements of the Zn II, Ni II, and Cr II column densities toward HD 85259 indicate that the LLCC has a modest "warm cloud" dust depletion pattern consistent with its low dust-to-gas ratio determined from H I 21 cm and 100 micron observations. In support of the inferred sheet-like geometry for the LLCC, a multi-epoch comparison of the Na I absorption toward a high-proper-motion background star reveals a 40% column density variation indicative of LLCC Na I structure on a scale of ~50 AU.

description: Recently, the Department of Homeland Security (DHS) identified the need to encourage hands-on learning throught cybersecurity competitions to address a shortage of skilled cyber defenders. Likewise, in 2019, Executive Order 13870 addressed the need to identify, challenge, and reward the United States government’s best cybersecurity practitioners and teams across offensive and defensive cybersecurity disciplines. Well-developed cybersecurity competitions offer a way for government organizations to fulfill that order. The Software Engineering Institute (SEI) has been working with the DHS Cybersecurity & Infrastructure Security Agency (CISA) to bring unique cybersecurity challenges to the federal cyber workforce. This blog post highlights the SEI’s experience developing cybersecurity challenges for the President's Cup Cybersecurity Competition and general-purpose guidelines and best practices for developing effective challenges. It also discusses tools the SEI has developed and made freely available to support the development of cybersecurity challenges. The SEI technical report 'Challenge Developmment Guidelines for Cybersecurity Competitions' explores these ideas in greater detail.
Population divergence and candidate signatures of natural selection in alpine and lowland ecotypes of the allotetrapoloid plant, Anemone multifida (Ranunculaceae)

description: Adaptation plays a central role in population divergence and speciation. Studying the evolutionary history of populations due to neutral evolutionary processes and the effects of natural selection enables the identification of genes under natural selection in the wild. In this thesis, I conducted a genome scan to elucidate candidate signatures of natural selection in alpine and lowland ecotypes of the allopolyploid plant, Anemone multifida. I found numerous signatures of divergent natural selection between alpine and lowland populations and between alpine populations, but natural selection appeared strongest in alpine environments. These results are consistent with findings in diploid species, but the neutral evolutionary structure of the polyploid A. multifida showed complex patterns of differentiation. Overall, these results indicate divergent natural selection has generated adaptation to alpine and lowland environments despite complex evolutionary history.

Reconfigurable RF Devices Using Pneumatic Control of Solid Dielectric Slugs

description: Many antennas reported with switchable polarization were designed using PIN diodes because of their reliability and commercial availability. However, in realizing more elaborate antennas, the biasing structures for these DC-controlled switching components become more complex, which leads to design limitations, losses, and undesired radiation. Other reconfigurable technologies, such as MEMS and liquid crystals, could be chosen for a particular application depending on various trade-offs, for example efficiency and ease of implementation. A recently developed scheme of using pneumatically controlled solid dielectric slugs offers an alternative to the existing technologies. These copper-backed slugs are confined within a dielectric channel adjacent to the conducting layer. A slug is either directly above or situated away from a slit in the conducting layer to realize its two switching states. Its translational movement is induced by a pneumatic pressure gradient inside the channel. The technology is low-loss and immune to RF distortion, and eliminates the need of DC biasing structures. This technique was incorporated in the design of a reconfigurable ring slot antenna capable of three polarization states (LP/LHCP/RHCP) at the 2.4-GHz ISM band. The multilayered structure consisted of low-loss dielectric laminate layers that were laser-machined to produce the precise profile and smooth edges required for repeatable movement of the slugs. The measured axial ratio (AR) bandwidth is 5%, which compares favourably to similar antennas. Parametric analyses were performed to accomplish the challenging task of realizing a design in which, the AR and impedance bandwidths of all three states shared a common frequency band centered around 2.4 GHz. An overall three-state bandwidth of 2.4% was achieved, which is the highest amongst similar antennas operating in the same frequency range. The measured antenna performance — radiation patterns, gain values, AR, and |S11| — in all three polarization states was consistent with the simulated performance. The pneumatic actuation of four slugs inside a channel to realize the three different states was successfully implemented, demonstrating that pneumatic slug control technology is suitable for inclusion in reconfigurable antennas.

Salmonid distribution in relation to stream temperatures in Fortune Creek, British Columbia : the influence of surface water and groundwater interactions
Creators: name: McGrath, Elinor Olivia
Publisher: name: University of British Columbia
Year: 2010

description: There is concern over the impacts of increased water temperature on salmonid populations in British Columbia’s (BC) Southern Interior. Groundwater influx may moderate stream temperatures and provides thermal refuge for salmonids. The objective of this study was to establish quantitative linkages among groundwater, water temperatures and juvenile coho salmon (Oncorhynchus kisutch Walbaum), Chinook salmon (Oncorhynchus tshawytscha Walbaum) and rainbow trout (Oncorhynchus mykiss Walbaum) in Fortune Creek, a small regulated stream in BC’s Southern Interior. In addition, this study quantified whether groundwater influx could provide thermal relief to salmonids during periods of heat stress. Salmonid enumeration and field data collection were carried out between July 2008 and June 2009. Generalized Linear Mixed Models (Poisson and logistic regression) were used to establish linkages between juvenile salmonids and physical and chemical fish habitat indicators. Thermal modeling of vertical groundwater fluxes in the streambed was conducted using the software VS2DH, which simulates fluid and conductive-convective heat transport. The relative influence of groundwater and stream discharge on stream temperatures was assessed using a conceptual energy balance approach. Statistical modeling confirmed that the distribution of juvenile salmonids was consistently related to water temperatures. Salmonids avoided reaches where maximum daily water temperatures exceeded 22°C, which was exceeded at most of the sites studied. Relationships to water chemistry were less consistent and existed almost exclusively in combination with water temperature variables. While groundwater flux to the stream was widespread, estimated upward fluxes were low (10-7 m/s) and were primarily constrained by low streambed hydraulic conductivities. The influence of advective cooling on stream temperatures in unshaded reaches was too small to provide significant thermal relief for salmonids. However, groundwater influx provided up to 88% of baseflows during the summer low flow season and was critical in maintaining flows in the creek. Conceptual energy balance modeling confirmed that low flows in Fortune Creek limit juvenile salmonid rearing by causing water temperatures to escalate. Recommendations for maintaining suitable water temperatures for juvenile salmonids include re-vegetation of the banks to provide shade and strategically supplementing flows to increase discharge at times of high water temperature potential.
A novel multi-component generalization of the short pulse equation and its multisoliton solutions
Creators: name: Matsuno, Yoshimasa
Publisher: name: arXiv
Year: 2011
Subjects: subject: Exactly Solvable and Integrable Systems (nlin.SI)
subject: FOS: Physical sciences

description: We propose a novel multi-component system of nonlinear equations that generalizes the short pulse (SP) equation describing the propagation of ultra-short pulses in optical fibers. By means of the bilinear formalism combined with a hodograph transformation, we obtain its multi-soliton solutions in the form of a parametric representation. Notably, unlike the determinantal solutions of the SP equation, the proposed system is found to exhibit solutions expressed in terms of pfaffians. The proof of the solutions is performed within the framework of an elementary theory of determinants. The reduced 2-component system deserves a special consideration. In particular, we show by establishing a Lax pair that the system is completely integrable. The properties of solutions such as loop solitons and breathers are investigated in detail, confirming their solitonic behavior. A variant of the 2-component system is also discussed with its multisoliton solutions.

description: Hadrontherapy is an emerging technique in cancer therapy that uses beams of charged particles. To meet the improved capability of hadrontherapy in matching the dose release with the cancer position, new dose monitoring techniques need to be developed and introduced into clinical use. The measurement of the fluxes of the secondary particles produced by the hadron beam is of fundamental importance in the design of any dose monitoring device and is eagerly needed to tune Monte Carlo simulations. We report the measurements done with charged secondary particles produced from the interaction of a 80 MeV/u fully stripped carbon ion beam at the INFN Laboratori Nazionali del Sud, Catania, with a Poly-methyl methacrylate target. Charged secondary particles, produced at 90$\degree$ with respect to the beam axis, have been tracked with a drift chamber, while their energy and time of flight has been measured by means of a LYSO scintillator. Secondary protons have been identified exploiting the energy and time of flight information, and their emission region has been reconstructed backtracking from the drift chamber to the target. Moreover a position scan of the target indicates that the reconstructed emission region follows the movement of the expected Bragg peak position. Exploting the reconstruction of the emission region, an accuracy on the Bragg peak determination in the submillimeter range has been obtained. The measured differential production rate for protons produced with $E^{\rm Prod}_{\rm kin} >$ 83 MeV and emitted at 90$\degree$ with respect to the beam line is: $dN_{\rm P}/(dN_{\rm C}dΩ)(E^{\rm Prod}_{\rm kin} > 83 {\rm ~MeV}, θ=90\degree)= (2.69\pm 0.08_{\rm stat} \pm 0.12_{\rm sys})\times 10^{-4} sr^{-1}$.

description: Abstract Electronic Mail (E-mail) is considered to be one of the most common and efficient ways of communication in today’s internet based world. The need for E-mail clients to keep up with this rising demand is expected. Utilization of the newest improvements and techniques in the machine learning and network analysis fields for problems, such as e-mail organization, relations detection, and explorative learning, is inevitable. Almost every E-mail client today, such as Microsoft Outlook, Thunderbird, Zimbra Desktop, Claws Mail and many more, operates in the same old-fashioned way with some minor differences in each. They provide basic features that lack intelligence. The main motivation of the NE-mail system discussed in this thesis is to leverage some of the other hidden benefits of the E-mail to its users by incorporating the related data mining and social network algorithms. NE-mail is an E-mail Mining and Social network tool implemented as a Microsoft Outlook® Plugin that provides classification, spam detection, clustering and graph- based social network functionalities in a novel way. Some NE-mail new functionalities are expected to change the way we look at the current E-mail client’s intelligence level.

description: We present the results of multi-epoch very long baseline interferometry (VLBI) water (H2O) maser observations carried out with the VLBI Exploration of Radio Astrometry (VERA) toward the Cepheus A HW3d object. We measured for the first time relative proper motions of the H2O maser features, whose spatio-kinematics traces a compact bipolar outflow. This outflow looks highly collimated and expanding through ~ 280 AU (400 mas) at a mean velocity of ~ 21 km/s (~ 6 mas/yr) without taking into account the turbulent central maser cluster. The opening angle of the outflow is estimated to be ~ 30{\circ}. The dynamical time-scale of the outflow is estimated to be ~ 100 years. Our results provide strong support that HW3d harbors an internal massive young star, and the observed outflow could be tracing a very early phase of star formation. We also have analyzed Very Large Array (VLA) archive data of 1.3 cm continuum emission obtained in 1995 and 2006 toward Cepheus A. The comparative result of the HW3d continuum emission suggests the possibility of the existence of distinct young stellar objects (YSOs) in HW3d and/or strong variability in one of their radio continuum emission components.

On optical self-phase modulation via collective atomic excitations in a Bose-Einstein condensate
Creators: name: Almutairi, Khulud
Publisher: name: Graduate Studies
Year: 2014
Subjects: Condensed Matter

description: This thesis presents a method for generating nonlinear phase shifts on superpositions of photon number states. Light is stored in a Bose-Einstein condensate (BEC) via electromagnetically induced transparency (EIT) memory techniques. Atomic collisions are exploited to generate a nonlinear phase shift of the stored state. The stored light is then revived with the nonlinear phase shift imprinted upon it. We show that this method can be used to develop a nonlinear-sign gate in the regime where the Thomas-Fermi and mean-field approximations are valid. We test these approximations using realistic parameters to find that these approximations pass the standard tests for validity in a single-component condensate. However, for the two-component condensates considered here, we find that these conditions are not sufficiently strict. Therefore, we find a stronger set of conditions and show for the same set of parameters that the approximations are invalid.

The Evolutionary Ecology of Facilitation: A Case Study Using Potentilla diversifolia

description: Facilitation occurs when the presence of one or more neighbours ameliorates abiotic conditions for a focal individual, leading to an increase in its absolute fitness. Facilitation is strong and widespread among sessile organisms such as plants. Nevertheless, the linkage between facilitation and patterns at the individual, population and species-level have only recently become subjects of investigation. My research sought to understand the role of facilitation as an agent of natural selection, and what, if any, consequences the amelioration of abiotic conditions by neighbours has for evolutionary processes such as local adaptation. Plant ecology and evolution along elevation gradients are well understood and form an excellent basis upon which to examine the ecological and evolutionary consequences of facilitation. Therefore, my studies considered Potentilla diversifolia, an alpine herbaceous perennial found in North America. A neighbour-removal experiment demonstrated that P. diversifolia experiences strongest facilitation at lower elevations within its range where the presence of neighbours reduces chronic heat stress. This association conflicts with conclusions of previous findings that the likelihood and strength of facilitation among alpine plants increases with elevation. A phenotypic selection experiment examined how the presence of neighbours affects the strength and direction of selection on stem length, leaf number, leaflet length and trichome density at different elevations. Neighbourhood significantly affected individual plant performance, but only stem length experienced directional selection, and this could not be clearly attributed to the effect of facilitation. Initial results from an ongoing reciprocal transplant experiment revealed that P. diversifolia is locally adapted to conditions at different elevations, and that the presence of neighbours appears to weaken the magnitude of local adaptation, especially at lower elevations where facilitation is the dominant interaction. Finally, an individual-based simulation model demonstrated that stable range limits could develop even where facilitation is the dominant interaction. The research presented here highlights the importance of considering species traits, and not just an individual’s location along an environmental gradient, when trying to understand the ecological and evolutionary consequences of facilitation. The results demonstrate that strong individual-level facilitation may not translate into significant consequences at the population- or species-level.

description: LHC-7 has narrowed down the mass range of the light Higgs boson. This result is consistent with the supergravity unification framework, and the current Higgs boson mass window implies a rather significant loop correction to the tree value pointing to a relatively heavy scalar sparticle spectrum with universal boundary conditions. It is shown that the largest value of the Higgs boson mass is obtained on the Hyperbolic Branch of radiative breaking. The implications of light Higgs boson in the broader mass range of 115 GeV to 131 GeV and a narrower range of 123 GeV to 127 GeV are explored in the context of the discovery of supersymmetry at LHC-7 and for the observation of dark matter in direct detection experiments.

description: Monte Carlo (MC) simulations are known to be the most accurate method to model radiation transport and absorbed dose. Geant4 application for tomographic emission (GATE) is a Monte Carlo simulation platform built and is relatively new at modeling radiotherapy systems. A MC model of the Brainlab Novalis Classic 6 MV was developed using GATE which will investigate GATE’s capabilities in the application of a stereotactic radiosurgery (SRS) dedicated linear accelerator. Measured depth dose distributions and dose profiles using an ion chamber, diode detector, and radiochromic film are used as reference measurements for the model. The model shows agreement with the measured data with greater than 90% of points passing a 3%/1mm gamma comparison, with the exception of smaller field sizes in the penumbra region which still agree within 3%/3mm. This model demonstrates GATE ability to model linacs and can be used in the future for research and clinical comparisons.

description: Previous research has demonstrated a tendency to pair nonwords like bouba with round shapes, and nonwords like kiki with sharp shapes. This is evidence against the arbitrariness of language, and supports the notion that phonemes can be inherently meaningful (i.e., sound symbolism). However many of these studies used explicit tasks. I investigated if the Bouba/Kiki effect would emerge on a more implicit measure: a priming task. Across six experiments I varied instructions and stimuli and in some experiments a priming effect was observed: participants were faster or more accurate when responding to shapes following a congruent than an incongruent nonword prime. The categorization of neutral shapes was also impacted by the type of nonword prime. These results provide some support for the possibility of sound symbolic priming.

description: We study the acoustic phonon response of crystals hosting a gapped time-reversal symmetry breaking electronic state. The phonon effective action can in general acquire a dissipationless "Hall" viscosity, which is determined by the adiabatic Berry curvature of the electron wave function. This Hall viscosity endows the system with a characteristic frequency, ω_v; for acoustic phonons of frequency ω, it shifts the phonon spectrum by an amount of order (ω/ω_v)^2 and it mixes the longitudinal and transverse acoustic phonons with a relative amplitude ratio of ω/ω_v and with a phase shift of +/- π/2, to lowest order in ω/ω_v. We study several examples, including the integer quantum Hall states, the quantum anomalous Hall state in Hg_{1-y}Mn_{y}Te quantum wells, and a mean-field model for p_x + i p_y superconductors. We discuss situations in which the acoustic phonon response is directly related to the gravitational response, for which striking predictions have been made. When the electron-phonon system is viewed as a whole, this provides an example where measurements of Goldstone modes may serve as a probe of adiabatic curvature of the wave function of the gapped sector of a system.

description: Data-related harm and injustice are commonly viewed through instrumental, procedural, distributional, or representational theories of social justice. These theories do not account for the social injustice that occurs through the lack of recognition of individuals when data are first conceptualized. We explore recognition of individuals in data conceptualization by drawing from information systems (IS) literature on data artifacts that acknowledges the fact that data are comprised of semantics and formats. Guided by recognition theory, we studied a project to expand sexual orientation and gender identity (SOGI) data collection at a public, U.S.-based LGBTQ+ -welcoming university. We found that while the actors involved worked towards recognizing in SOGI data the fact that identities are layered, non-binary, plural, and fluid, the data themselves still misrecognized individuals due to data warping. We argue that data warping occurs because of recognition concessions between social recognition through data semantics and systems recognition through data formats. Such concessions are both necessary for some recognition but accessory to misrecognition. Our findings have implications for recognition theory, data justice, and information systems research, as well as for personal data in practice.

description: The rapid development of DNA microarray technology enables researchers to measure the expression levels of thousands of genes simultaneously and allows biologists easily gain insight into the complex interaction in tumours on gene expression levels. Its application in cancer studies has been shown great success in both diagnosis and elucidating the pathological mechanism. However, DNA microarray data usually contains thousands of genes and most of them are proved to be uninformative and redundant. Meanwhile, small size of samples of microarray data undermines the diagnosis accuracy of statistical models. Thereby, selecting highly discriminative genes from raw gene expression data can improve the performance of cancer classification and cut down the cost of medical diagnosis. This M.Sc. thesis proposes and investigates a new method of selecting highly discriminative genes for cancer classification based on DNA microarray data. For two-group classification problem, the Bhattacharyya distance is proposed to measure the dissimilarity in gene expression levels between the two groups. For any particular gene, we calculate the Bhattacharrya distance between the two groups based on the expression levels of that particular gene. We use the calculated distances, one for each gene, as a criteria to rank all the genes. Finally, support vector machine is utilized to obtain the optimal subset of genes achieving the lowest misclassification rate. Compared with the other two methods, SWKC (supervised weighted kernel clustering) (Shim et al., 2009) and SVM-RFE (support vector machine with recursive feature elimination) (Guyon et al., 2002), the proposed method is shown to be more effective and sensitive to differentially expressed genes. In the simulation study, the proposed method has much higher recovery rate than the other two methods. Comparisons among these three gene selection methods are also made through two real DNA microarray datasets, the colon dataset and the leukemia dataset, that are publicly available. Based on three classification performance indexes, i.e. average number of genes selected, average number of classification errors in test set and misclassification rate, the proposed method gets slightly better classification results than SVM-RFE for the colon dataset while at a much less computation cost. It also achieves better classification results than the SWKC methods in both datasets. Finally, we discuss that in future work improvement in performance could be achieved by introducing kernel density estimators and replacing Bhattacharyya distance with Hellinger distance as a feature selection criteria. Since kernel density estimation is free of distribution assumptions, under which the classification results would be more robust than that obtained by the Bhattacharyya distance under normal assumption.
Comment to a paper [arXiv:1103.4937] of M. Villata on antigravity

description: In a recent paper of M. Villata [arXiv:1103.4937], it is claimed that "antigravity appears as a prediction of general relativity when CPT is applied." However, the present paper argues that Villata puts the cart before the horse qua methodology, and that the resulting theory cannot be reconciled with the ontological presuppositions of general relativity. The conclusion is that Villata's suggestion for the physics that might underlie a gravitational repulsion of matter and antimatter is not acceptable in its current state of development.

Optical trapping using a photonic crystal cavity : design and sample fabrication
Creators: name: Mirsadeghi, Seyed Hamed
Publisher: name: University of British Columbia
Year: 2010

description: A photonic crystal (PC) structure for trapping a 50nm radius dielectric particle at a precise location on a silicon surface in an organic solvent environment has been designed and all of its key components have been fabricated. The high gradient of electric field intensity in a PC cavity mode, with wavelength ~ 1.5 microns, exerts a radiation force toward the center of the cavity. The Finite Difference Time Domain (FDTD) modeling method was used to design a symmetric (input/output) structure that consists of two grating couplers, two parabolic tapered waveguides, two single mode ridge waveguides, two photonic crystal waveguides and a single three-missing-hole (L3) PC cavity. The radiation force on the dielectric sphere was exactly calculated using FDTD simulations to evaluate the Maxwell Stress Tensor (MST) in the presence of the particle to be trapped. This result was compared to that obtained using the simpler dipole approximation, and good agreement between them was found. The fabrication of the structure was done by electron beam lithography and chlorine plasma etching. The Q factors for some of the fabricated samples were measured from the cavity enhanced photoluminescence emission of PbSe quantum dots deposited on the sample surface. A vertical Q factor of 3600 (in vacuum environment) was measured for an isolated cavity, which corresponds to a Qv of 3800 ( in solvent environment) in the FDTD simulations. Also, the Q, of the overall structure (cavity and the waveguides) was measure to be 1050 in vacuum, which from simulations is equivalent to a Q of 1800 in a solvent. These Q values and the resonant frequencies of the modes are in close, but not perfect agreement with the simulation results.
