description: If thick disks are ubiquitous and a natural product of disk galaxy formation and/or evolution processes, all undisturbed galaxies which have evolved during a significant fraction of a Hubble time should have a thick disk. The late-type spiral galaxy NGC 4244 has been reported as the only nearby edge-on galaxy without a confirmed thick disk. Using data from the Spitzer Survey of Stellar Structure in Galaxies (S4G) we have identified signs of two disk components in this galaxy. The asymmetries between the light profiles on both sides of the mid-plane of NGC 4244 can be explained by a combination of the galaxy not being perfectly edge-on and a certain degree of opacity of the thin disk. We argue that the subtlety of the thick disk is a consequence of either a limited secular evolution in NGC 4244, a small fraction of stellar material in the fragments which built the galaxy, or a high amount of gaseous accretion after the formation of the galaxy.

description: We describe the effect that new atomic calculations, including fully-relativistic R-matrix calculations of collisional excitation rates and level-specific dielectronic and radiative recombination rates, have on line ratios from the astrophysically significant ion Ne IX. The new excitation rates systematically change some predicted Ne IX line ratios by 25% at temperatures at or below the temperature of maximum emissivity (4x10^6 K), while the new recombination rates lead to systematic changes at higher temperatures. The new line ratios are shown to agree with observations of Capella and sigma^2 CrB significantly better than older line ratios, showing that 25-30% accuracy in atomic rates is inadequate for high-resolution X-ray observations from existing spectrometers.

description: Resonance modes in single crystal sapphire ($α$-Al$_2$O$_3$) exhibit extremely high electrical and mechanical Q-factors ($\approx 10^9$ at 4K), which are important characteristics for electromechanical experiments at the quantum limit. We report the first cooldown of a bulk sapphire sample below superfluid liquid helium temperature (1.6K) to as low as 25mK. The electromagnetic properties were characterised at microwave frequencies, and we report the first observation of electromagnetically induced thermal bistability in whispering gallery modes due to the material $T^3$ dependence on thermal conductivity and the ultra-low dielectric loss tangent. We identify "magic temperatures" between 80 to 2100 mK, the lowest ever measured, at which the onset of bistability is suppressed and the frequency-temperature dependence is annulled. These phenomena at low temperatures make sapphire suitable for quantum metrology and ultra-stable clock applications, including the possible realization of the first quantum limited sapphire clock.

description: We study the class of spacelike surfaces in the four-dimensional Minkowski space whose mean curvature vector at any point is a non-zero spacelike vector or timelike vector. These surfaces are determined up to a motion by eight invariant functions satisfying some natural conditions. The subclass of Chen surfaces is characterized by the condition one of these invariants to be zero. In the present paper we describe all Chen spacelike rotational surfaces of hyperbolic or elliptic type.

The effect of heme oxygenase-1 on breast cancer metastasis in vitro and in vivo
Creators: name: Kim, Ada Yongyeon
Publisher: name: University of British Columbia
Year: 2014

description: The metastatic spread of cancer is linked to over 90% of cancer-related deaths. Therapies designed to prevent the dissemination of metastatic cells from the primary tumour is a therapeutic strategy to improve outcome for patients at risk of developing metastatic disease. Heme oxygenase-1 (HMOX1) is the rate-limiting enzyme in heme catabolism and is induced by various stress stimuli. The role of HMOX1 in breast cancer metastasis is conflicting with some groups indicating that HMOX1 promotes metastasis while others indicating that HMOX1 reduces metastatic spread. Previously in our laboratory, HMOX1 expression was chemically induced with hemin, a potent and effective HMOX1 inducer, in murine mammary carcinoma cells to determine the effect of HMOX1 on tumour cell migration and invasion. Hemin reduced migration and invasion of all three cell lines when assessed by Boyden chamber transwell assays. Therefore, we hypothesize that HMOX1 reduces breast cancer metastasis by decreasing tumour cell migration and invasion. We used three different murine mammary carcinoma cell lines as models for breast cancer: 67NR – noninvasive/nonmetastatic, 4TO7 – invasive/metastatic, 4T1 - highly aggressive metastatic behavior. We increased HMOX1 expression genetically or by chemical induction with another HMOX1 inducer, cobalt protoporphyrin (CoPP), to determine the effect of HMOX1 on migration and invasion. CoPP and HMOX1 overexpression reduced migration of all tumour cells in vitro. Interestingly, HMOX1 overexpression decreased invasion of 4T1 cells, but increased the invasion of 67NR and 4TO7 cells, modeling the dichotomy of HMOX1’s influence on breast cancer cell invasion. We also assessed the effect of HMOX1 overexpression and knockdown on lung metastases in vivo. In 4T1 tumours, HMOX1 overexpression had no effect on primary tumour growth or lung metastases. On the other hand, in 4T1 tumours with HMOX1 knockdown, there was a reduction in tumour growth and in lung metastases.

description: The heterogeneous condensation of a Lennard-Jones vapor onto a nanoscale seed particle is studied using molecular dynamics simulations. Measuring the nucleation rate and the height of the free energy barrier using the mean first passage time method shows that the presence of a weakly interacting seed has little effect on the work of forming very small cluster embryos but accelerates the rate by lowering the barrier for larger clusters. We suggest that this results from a competition between the energetic and entropic features of cluster formation in the bulk and at the heterogeneity. As the interaction is increased, the free energy of formation is reduced for all cluster sizes. We also develop a simple phenomenological model of film formation on a small seed that captures the general features of the nucleation process for small heterogeneities. A comparison of our simulation results with the model shows that heterogeneous classical nucleation theory provides a good estimate of the critical size of the film but significantly over-estimates the size of the barrier.

Seasonal business diversification of ski resorts and the effects on forest management : effects on trees and people due to a shift from winter only to year-round business of ski resorts in British Columbia
Creators: name: De Grave, Arnaud
Publisher: name: University of British Columbia
Year: 2014

description: Some ski resorts are shifting their business models from winter-only snow-based activities to year-round tourism. This may be happening as a result of climate change or because of a change in recreationists' behaviour, amongst other causes.  This research seeks to understand the impacts of such shifts on forest management in the areas surrounding the ski resorts. It investigates the effects of these shifts on the boundaries of the the impacted land used by residents and visitors. These effects are evaluated from an environmental impact point of view and also from a socio-economic point of view. The research also attempts to relate these shifts to factors such as location, timing and scale effects related to the size of the resorts. Four case studies were chosen: Whistler, Sun Peaks resort, Hemlock Valley resort and Mount Washington resort. In each case, opinions of stakeholders were collected through semi-structured interviews and the data were analysed by a method inspired by grounded theory and Qualitative Data Analysis. Results identify factors and mechanisms that allow a shift to happen in a ski resort and propose dates for the two case studies where the shift occurred. The strength of the communities and their incorporation into resort municipalities are identified as critical factors. Forestry practices are found to have been impacted by the shift because of a change of management values towards more recreation and visuals values. An increase of the amount of stakeholders with varied vested interests in the forests is believed to improve the forests' management. The number of people experiencing nature during the summer months and their attitudes are believed to increase awareness about the environment. This increased awareness induces scrutiny and self-regulation through information technologies. Moreover, the quality of life of shifted communities is shown to be increased and linked to a more environmentally friendly land stewardship. This acts as a positive feedback loop for a successful shift and change in forest management.

description: Establishing hidden communication is an important subject of discussion that has gained increasing importance nowadays with the development of the internet. One of the key methods for establishing hidden communication is steganography. Modern day steganography mainly deals with hiding information within files like image, text, html, binary files etc. These file contains small irrelevant information that can be substituted for small secret data. To store a high capacity secret data these carrier files are not very supportive. To overcome the problem of storing the high capacity secret data with the utmost security fence, we have proposed a novel methodology for concealing a voluminous data with high levels of security wall by using movie clip as a carrier file.

description: The results of three-color BVR photometric study of a recently discovered unusual binary system VSX J052807.9+725606 = USNO-B1.0 1629-0064825 are presented. This system is very similar to V361 Lyr, which was assumed to be unique. We confirmed a strong asymmetry of the phase curve and found the wavelength dependence of the amplitude. This is interpreted by a "direct impact" model with a "hot spot" in the atmosphere of the accreting component. Color temperatures are determined. Characteristics of the "hot spot" are estimated. We also calculated the new ephemeris for VSX J052807.9+725606.

Grammar-Based Geodesics in Semantic Networks

Year: 2010
Subjects: subject: Data Structures and Algorithms (cs.DS)
subject: FOS: Computer and information sciences

description: A geodesic is the shortest path between two vertices in a connected network. The geodesic is the kernel of various network metrics including radius, diameter, eccentricity, closeness, and betweenness. These metrics are the foundation of much network research and thus, have been studied extensively in the domain of single-relational networks (both in their directed and undirected forms). However, geodesics for single-relational networks do not translate directly to multi-relational, or semantic networks, where vertices are connected to one another by any number of edge labels. Here, a more sophisticated method for calculating a geodesic is necessary. This article presents a technique for calculating geodesics in semantic networks with a focus on semantic networks represented according to the Resource Description Framework (RDF). In this framework, a discrete "walker" utilizes an abstract path description called a grammar to determine which paths to include in its geodesic calculation. The grammar-based model forms a general framework for studying geodesic metrics in semantic networks.

description: We investigate the effect of a distorted neutron star dipole magnetic field on pulsar pair cascade multiplicity and pair death lines. Using a simple model for a distorted dipole field that produces an offset polar cap, we derive the accelerating electric field above the polar cap in space charge limited flow. We find that even a modest azimuthally asymmetric distortion can significantly increase the accelerating electric field on one side of the polar cap and, combined with a smaller field line radius of curvature, leads to larger pair multiplicity. The death line for producing pairs by curvature radiation moves downward in the P-Pdot diagram, allowing high pair multiplicities in a larger percentage of the radio pulsar population. These results could have important implications for the radio pulsar population, high energy pulsed emission and the pulsar contribution to cosmic ray positrons.

An empirical study of practical, theoretical and online variants of random forests
Creators: name: Matheson, David
Publisher: name: University of British Columbia
Year: 2014

description: Random forests are ensembles of randomized decision trees where diversity is created by injecting randomness into the fitting of each tree. The combination of their accuracy and their simplicity has resulted in their adoption in many applications. Different variants have been developed with different goals in mind: improving predictive accuracy, extending the range of application to online and structure domains, and introducing simplifications for theoretical amenability. While there are many subtle differences among the variants, the core difference is the method of selecting candidate split points. In our work, we examine eight different strategies for selecting candidate split points and study their effect on predictive accuracy, individual strength, diversity, computation time and model complexity. We also examine the effect of different parameter settings and several other design choices including bagging, subsampling data points at each node, taking linear combinations of features, splitting data points into structure and estimation streams and using a fixed frontier for online variants. Our empirical study finds several trends, some of which are in contrast to commonly held beliefs, that have value to practitioners and theoreticians. For variants used by practitioners the most important discoveries include: bagging almost never improves predictive accuracy, selecting candidate split points at all midpoints can achieve lower error than selecting them uniformly at random, and subsampling data points at each node decreases training time without affecting predictive accuracy. We also show that the gap between variants with proofs of consistency and those used in practice can be accounted for by the requirement to split data points into structure and estimation streams. Our work with online forests demonstrates the potential improvement that is possible by selecting candidate split points at data points, constraining memory with a fixed frontier and training with multiple passes through the data.

description: The characters of the angular distributions of quark jets and gluon jets with different flavors are carefully studied after introducing the cone angle of jets. The quark jets and gluon jets are identified from the 3-jet events which are produced by Monte Carlo simulation Jetset7.4 in e+e- collisions at $\sqrt s$=91.2GeV. It turns out that the ranges of angular distributions of gluon jets are obviously wider than that of quark jets at the same energies. The average cone angles of gluon jets are much larger than that of quark jets. As the multiplicity or the transverse momentum increases, the cone-angle distribution without momentum weight of both the quark jet and gluon jet all increases, i.e the positive linear correlation are present, but the cone-angle distribution with momentum weight decreases at first, then increases when n > 4 or p_t > 2 GeV. The characters of cone angular distributions of gluon jets produced by quarks with different flavors are the same, while there are obvious differences for that of the quark jets with different flavors.

description: An epidemiological model which incorporates synergistic effects that allow the infectivity and/or susceptibility of hosts to be dependent on the number of infected neighbours is proposed. Constructive synergy induces an exploitative behaviour which results in a rapid invasion that infects a large number of hosts. Interfering synergy leads to a slower and sparser explorative foraging strategy that traverses larger distances by infecting fewer hosts. The model can be mapped to a dynamical bond-percolation with spatial correlations that affect the mechanism of spread but do not influence the critical behaviour of epidemics.

description: Valve surgery is common in cardiac procedures, with fasteners like COR-KNOT® and hand-tied knots used for knot securing. This study compares their efficacy in valve surgery patients. We searched PubMed, SCOPUS, and Cochrane Central until August 2023. Outcomes assessed included aortic cross-clamp time (AXT), cardiopulmonary bypass (CPB) time, valvular regurgitation, mortality, prolonged ventilatory support, atrial fibrillation, postoperative left ventricular ejection fraction (LVEF), and renal failure. Subgroup analysis was performed for minimally invasive and open cardiac surgery. We used a random effects model for analysis. We included eight observational studies and two randomized controlled trials (RCTs) with a total of 1.411 participants. COR-KNOT significantly reduced AXT [MD -15.14, 95 % CI (-18.57, -11.70), P<0.00001] and CPB time [MD -12.38, 95 % CI (-14.99, -9.77), P<0.00001]. Valvular regurgitation [RR 0.40, 95 % CI (0.26, 0.61), P<0.0001] and need for prolonged ventilatory support [RR 0.29, 95 % CI (0.13, 0.65), P=0.003] were significantly lower with COR-KNOT. There were no significant differences in mortality [RR 0.39, 95 % CI (0.09, 1.69), P=0.44], atrial fibrillation [RR 1.03, 95 % CI (0.83, 1.27), P=0.81], LVEF changes [MD 0.05, 95 % CI (−1.37, 1.47), P = 0.95], or renal failure [RR 0.87, 95 % CI (0.16, 4.80), P = 0.87]. COR-KNOT devices reduce operative time and valvular regurgitation without increasing mortality or adverse outcomes. This supports their use in enhancing surgical efficiency and patient outcomes. However, ongoing discussions about suturing techniques, especially in minimally invasive procedures, highlight the need for further research and consensus among practitioners.

description: Cloud computing allows shared computer and storage facilities to be used by a multitude of clients. While cloud management is centralized, the information resides in the cloud and information sharing can be implemented via off-the-shelf techniques for multiuser databases. Users, however, are very diffident for not having full control over their sensitive data. Untrusted database-as-a-server techniques are neither readily extendable to the cloud environment nor easily understandable by non-technical users. To solve this problem, we present an approach where agents share reserved data in a secure manner by the use of simple grant-and-revoke permissions on shared data.

Elucidating the function of arabinogalactan proteins during wood formation
Creators: name: Xi, Li
Publisher: name: University of British Columbia

description: Arabinogalactan proteins (AGPs) are cell wall proteins with abundant glycosylation, belonging to the large, multi-gene hydroxyproline-rich glycoprotein (HRGP) family. It has been reported that AGPs may contribute to cell expansion, xylem cell differentiation and secondary cell wall deposition. However, the roles of specific AGP in wood developmental processes have never been thoroughly elucidated. Therefore, the objective of this thesis was to investigate the functional role(s) of three AGPs in wood cell wall development. Specifically, the lysine-rich AGP18; a classical AGP, AGP9; and an AGP peptide, AGP14 were studied, because they demonstrated high gene expression levels in the developing xylem of Populus trichocarpa during transcriptome re-sequencing initiatives. Based on the phenotypic changes observed when PtAGP18 was down-regulated in transgenic poplar trees and Arabidopsis atagp18 T-DNA mutant analyses, I showed roles for AGP18 in fiber cell shape and fiber secondary cell wall formation (Chapter 2). Moreover, the poplar PtAGP18 was able to complement the Arabidopsis atagp18 T-DNA mutants which displayed altered fiber shape and cell wall thickness, indicating that these two genes are functionally equivalent (Chapter 2). Analysis of the growth of Arabidopsis hypocotyls cultivated in darkness revealed that AGP18 is involved in cell expansion (Chapter 2). In parallel, I showed that the AGP9 affects xylem vessel differentiation and vessel cell expansion (Chapter 3). A role for AGP9 in cell expansion was also demonstrated with Arabidopsis agp9 mutant hypocotyls grown in the dark (Chapter 3). Furthermore, AGP14 appears to contribute to cell wall formation in poplar (Chapter 4). Taken together, the functional characterization of these AGPs suggests that AGP18 and AGP9 play roles in the development of fibers and vessels, respectively. However, further research is needed to delineate the exact cellular and molecular mechanisms through which AGPs contribute to secondary xylem development.

" Tuberculocythere horrida" Ayress, 1988 *: 629; pI. 22, figs 13-15. Remarks. Material illustrated here is from DSDP Site 254 in the eastern Indian Ocean, and represents the only record of this species outside the North Atlantic. The Indian Ocean specimens differ slightly from the Atlantic material in having a more inflated posteroventral tubercle which may be attributable to geographical variation. In several species of Hemiparacytheridea the degree of inflation of the lateral tubercles can be seen to be rather variable and end members with very swollen tubercles have been placed in Tuberculocythere Colalongo & Pasini, 1980. The tubercular inflation is not, therefore, considered to represent a natural generic character, and for this reason Tuberculocythere is not used here.

description: Efficient detection of trace water was important before use in water-sensitive reactions. Herein, a fluorescence sensor 1,4-bis((E)-(2-(benzo[d]thiazol-2-yl)hydrazineylidene)methyl)benzene (DHB) was designed and synthesised by a simple one-step reaction using 2-hydrazinobenzothiazole and terephthalaldehyde as raw materials. DHB showed aggregation-induced emission characteristics in solid state and 1,4-dioxane/H2O mixture. In addition, the fluorescent colour changes in IPA and fluorescence quenching in N,N-dimethylformamide (DMF), N,N-dimethylacetamide (DMA), dimethyl sulphoxide (DMSO), glycerine (GI), and 1,3-propanediol (1,3-PDO) were obviously observed with increasing water content, making DHB a highly sensitive fluorescent sensor for water detection with a detection limit of 0.174% for IPA, 0.040% for DMSO, 0.067% for DMF, 0.039% for DMA, 0.069% for 1,3-PDO, and 0.013% for GI, respectively. Further, DHB displayed fluorescence colorimetric response to water in solid state. 1H NMR titration indicated that the sensing mechanism for the detection of trace water was form hydrogen bonds between H2O molecule and amino group of DHB.
The bosonic birthday paradox

description: We motivate and prove a version of the birthday paradox for $k$ identical bosons in $n$ possible modes. If the bosons are in the uniform mixed state, also called the maximally mixed quantum state, then we need $k \sim \sqrt{n}$ bosons to expect two in the same state, which is smaller by a factor of $\sqrt{2}$ than in the case of distinguishable objects (boltzmannons). While the core result is elementary, we generalize the hypothesis and strengthen the conclusion in several ways. One side result is that boltzmannons with a randomly chosen multinomial distribution have the same birthday statistics as bosons. This last result is interesting as a quantum proof of a classical probability theorem; we also give a classical proof.

Modeling the net greenhouse gas balance of projects that displace gasoline with wood ethanol from short rotation tree plantations
Creators: name: Ristea, Catalin
Publisher: name: University of British Columbia
Year: 2015

description: Projects that establish fast growing tree plantations and substitute gasoline with ethanol from the resulting wood biomass have the potential to reduce atmospheric carbon dioxide and other greenhouse gas (GHG) emissions and to increase terrestrial carbon (C) stocks. However, current methodologies for evaluating the net GHG balance of biofuel projects do not consider specifically the life cycle impacts of biogenic C dynamics and the emissions from decomposition of dead organic matter (DOM). This dissertation proposes the Carbon Balance and Biomass to Biofuel Optimization planning model (C3BO), which determines the net GHG balance of biofuel projects on a life cycle basis from initial land-use change, establishment of plantations and construction of biorefinery, through conversion of biomass into ethanol and final use in internal combustion engines. The novel approach of the C3BO model is the inclusion of initial C stocks, soil organic matter and biogenic C dynamics to the project GHG balance calculations. C3BO model results show that the GHG balance of biofuel projects is most sensitive to initial carbon stocks and biorefinery emissions. The potential direct land-use change impacts on initial C stocks (including the initial biomass removal and the affect of the project on the emissions from decay of soil organic matter) can affect the life-cycle net GHG balance, clearly indicating that they need to be included in life cycle analyses of biofuel projects. The magnitude of the reductions in emissions, compared with the fossil fuel baseline, is highly dependent on the length of the project time horizon: the GHG balance changes with project length, and the impact of input variables also changes with time. Biofuel projects can produce fewer emissions but they can also result in more emissions than the displaced fossil fuel system. The viability of biofuel projects as worthwhile climate mitigation strategies depends on project-specific conditions that need to be properly assessed on a project-by-project basis. This study also suggests that ethanol production cost is twice as sensitive to conversion efficiency than to biomass yield. Improving conversion efficiency will result in much larger benefits than improving biomass yield, in terms of reducing ethanol production costs.
Polaronic slowing of fermionic impurities in lattice Bose-Fermi mixtures

description: We generalize the application of small polaron theory to ultracold gases of Ref. [\onlinecite{jaksch_njp1}] to the case of Bose-Fermi mixtures, where both components are loaded into an optical lattice. In a suitable range of parameters, the mixture can be described within a Bogoliubov approach in the presence of fermionic (dynamic) impurities and an effective description in terms of polarons applies. In the dilute limit of the slow impurity regime, the hopping of fermionic particles is exponentially renormalized due to polaron formation, regardless of the sign of the Bose-Fermi interaction. This should lead to clear experimental signatures of polaronic effects, once the regime of interest is reached. The validity of our approach is analyzed in the light of currently available experiments. We provide results for the hopping renormalization factor for different values of temperature, density and Bose-Fermi interaction for three-dimensional $^{87}\rm{Rb}-^{40}\rm{K}$ mixtures in optical lattice.

description: The Coma cluster of galaxies hosts the brightest radio halo known and has therefore been the target of numerous searches for associated inverse Compton (IC) emission, particularly at hard X-ray energies where the IC signal must eventually dominate over thermal emission. The most recent search with the Suzaku Hard X-ray Detector (HXD) failed to confirm previous IC detections with RXTE and BeppoSAX, instead setting an upper limit 2.5 times below their nonthermal flux. However, this discrepancy can be resolved if the IC emission is very extended, beyond the scale of the cluster radio halo. Using reconstructed sky images from the 58-month Swift BAT all sky survey, the feasibility of such a solution is investigated. Building on Renaud et al., we test and implement a method for extracting the fluxes of extended sources, assuming specified spatial distributions. BAT spectra are jointly fit with an XMM-Newton EPIC-pn spectrum derived from mosaic observations. We find no evidence for large-scale IC emission at the level expected from the previously detected nonthermal fluxes. For all nonthermal spatial distributions considered, which span the gamut of physically reasonable IC models, we determine upper limits for which the largest (most conservative) limit is <4.2x10^{-12} erg/s/cm^2 (20-80 keV), which corresponds to a lower limit on the magnetic field B>0.2uG. A nominal flux upper limit of <2.7x10^{-12} erg/s/cm^2, with corresponding B>0.25uG, is derived for the most probable IC distribution given the size of the radio halo and likely magnetic field radial profile.

description: Offering of different attractive opportunities by different wireless technologies trends the convergence of heterogeneous networks for the future wireless communication system. To make a seamless handover among the heterogeneous networks, the optimization of the power consumption, and optimal selection of interface are the challenging issues for convergence networks. The access of multi interfaces simultaneously reduces the handover latency and data loss in heterogeneous handover. The mobile node (MN) maintains one interface connection while other interface is used for handover process. However, it causes much battery power consumption. In this paper we propose an efficient interface selection scheme including interface selection algorithms, interface selection procedures considering battery power consumption and user mobility with other existing parameters for overlaying networks. We also propose a priority based network selection scheme according to the service types. MN's battery power level, provision of QoS/QoE in the target network and our proposed priority parameters are considered as more important parameters for our interface selection algorithm. The performances of the proposed scheme are verified using numerical analysis.
