Seismic design and performance evaluation of dual-fused h-frame system
Creators: name: Etebarian, Hamidreza
Publisher: name: University of British Columbia
Year: 2018

description: A Dual-Fused H-Frame (DFHF) is an efficient structural system that combines Damped H-Frame (DHF) modules with Welded Wide Flange Fuses (WWFFs) to create a structural solution which is efficient in construction and more seismic resilient. Each DHF module consists of two columns pin connected to a beam with two buckling restrained knee braces (BRKBs). Each DHF module can be prefabricated in the factory, shipped to the site and connected vertically using simple bolt connections. The connections between the DHF modules have relatively small moment demand which makes the design, fabrication and construction of the DHF modules very efficient. Once the DHF modules have been assembled vertically, the bays of the DHF can be connected using WWFFs. WWFFs are simple shear connectors which can dissipate stable earthquake energy. In this paper, two prototype DFHF buildings of varying heights (3- and 9- story) are designed using the Equivalent Energy Design Procedure (EEDP). EEDP is a novel design method which is developed to design innovative systems, where the structural system can achieve different performance objectives under different earthquake shaking intensities. To verify the performance of the DFHF, advanced finite element models are developed using OpenSees and subjected to an extensive array of time history analyses. The results show that the proposed EEDP designed DFHF can achieve the targeted performance objectives under different seismic shaking intensities. In addition, DFHF has sufficient margin of safety against collapse. Hence the proposed DFHF can be used as an efficient structural system in high seismic zone.

description: Using the isospin-dependent quantum molecular dynamics model we study the isospin effects on the disappearance of flow for the reactions of $^{58}Ni$ + $^{58}Ni$ and $^{58}Fe$ +$^{58}Fe$ as a function of impact parameter. We found good agreement between our calculations and experimentally measured energy of vanishing flow at all colliding geometries. Our calculations reproduce the experimental data within 5%(10%) at central (peripheral) geometries.

description: HD 46375 is known to host a Saturn-like exoplanet orbiting at 0.04 AU from its host star. Stellar light reflected by the planet was tentatively identified in the 34-day CoRoT run acquired in October-November 2008. We constrain the properties of the magnetic field of HD 46375 based on spectropolarimetric observations with the NARVAL spectrograph at the Pic du Midi observatory. In addition, we use a high-resolution NARVAL flux spectrum to contrain the atmospheric parameters. With these constraints, we perform an asteroseismic analysis and modelling of HD 46375 using the frequencies extracted from the CoRoT light curve. We used Zeeman Doppler imaging to reconstruct the magnetic map of the stellar surface. In the spectroscopic analysis we fitted isolated lines using 1D LTE atmosphere models. This analysis was used to constrain the effective temperature, surface gravity, and chemical composition of the star. To extract information about the p-mode oscillations, we used a technique based on the envelope autocorrelation function (EACF). From the Zeeman Doppler imaging observations, we observe a magnetic field of ~5 gauss. From the spectral analysis, HD 46375 is inferred to be an unevolved K0 type star with high metallicity [Fe/H]=+0.39. Owing to the relative faintness of the star (m_hip=8.05), the signal-to-noise ratio is too low to identify individual modes. However, we measure the p-mode excess power and large separation Delta nu_0=153.0 +/- 0.7 muHz. We are able do constrain the fundamental parameters of the star thanks to spectrometric and seismic analyses. We conclude that HD 46375 is similar to a young version of Alpha-CenB. This work is of special interest because of its combination of exoplanetary science and asteroseismology, which are the subjects of the current Kepler mission and the proposed PLATO mission.

description: In this Letter, we report on a low-resolution spectroscopic survey for Li-rich K giants among 2000 low mass (M <= 3 Msun) giants spanning the luminosity range from below to above the luminosity of the clump. Fifteen new Li-rich giants including four super Li-rich K giants (A(Li) >= 3.2) were discovered. A significant finding is that there is a concentration of Li-rich K giants at the luminosity of the clump or red horizontal branch. This new finding is partly a consequence of the fact that our low-resolution survey is the first large survey to include giants well below and above the RGB bump and clump locations in the HR diagram. Origin of the lithium enrichment may be plausibly attributed to the conversion of 3He via 7Be to 7Li by the Cameron-Fowler mechanism but the location for onset of the conversion is uncertain. Two possible opportunities to effect this conversion are discussed: the bump in the first ascent of the red giant branch (RGB) and the He-core flash at the tip of the RGB. The finite luminosity spread of the Li-rich giants serves to reject the idea that Li enhancement is, in general, a consequence of a giant swallowing a large planet.

description: 1° Desmacella Peachi var. trirhaphis n. var. PI. XVIII, fig. 9 et PI. XXL fig. 35. Trois spécimens entiers. Éponge massive, sessile, irrégulière, à surface frisée, à structure fibreuse, de consistance ferme, de couleur grisâtre dans l'alcool. Oscules épars, peu nombreux, assez larges (3 mm.). Cette variété ne s'écarte guère du type par ses caractères extérieurs. Par sa spiculation, elle eu diffère surtout à cause de l'existence d'une troisième sorte de trichodragmates, totalement absente dans le spécimen de Bowerbank (îles Shetland), dans celui que j'ai trouvé à Luc (Calvados) et dans les Desmacella Peachi var. stellifera de Fristedt (îles Koster et Vâderô). Spiculation. Styles lisses, assez forts mais pas très longs, plus ou moins courbés, à pointe courte; longueur 350 p., épaisseur 18 p.. Sigmates de différentes tailles. On peut assez facilement les grouper en trois catégories: les plus grands, très ouverts comme ceux du type de l'espèce (1, vol. LX1 II, fig. 5), longs de 80 [a, épais de 3 p.; les moyens, à tige peu courbée et à crochets peu écartés de la tige, longs de 45 p., épais de 2 ^ (ce sont les plus nombreux); les plus petits, bien arrondis, grêles, longs de 18p,, épais de 1 ^ seulement. Dans le spécimen de Luc, il n'est guère possible de grouper ces microsclères en plus de deux catégories, correspondant à la plus robuste et à la plus faible. Trichodragmates de trois catégories très nettes et sans intermédiaires: les plus petits, formés de microxes fusiformes, longs de 40 [x, épais de 3 p., par paquets de quatre à huit; d'autres, les plus nombreux, composés de raphides, longs de 150jj., linéaires, en faisceaux compacts; les autres enfin, presque aussi abondants que les premiers, faits de microxes fusiformes, longs de 170 {t, épais de 5 jx au centre. Ce sont ceux de la dernière catégorie qui font défaut chez Besmacella Peachi. Tous ces raphides sont droits, sans exception. On n'en trouve de semblables que chez Besmacella variantia (Bow.) et Besmacella fortis. Encore peuton se demander si Besmacella variantia, plus correctement B. varians, est bien spécifiquement distincte de B. Peachi.

description: We consider the planar MHV amplitude in N=4 supersymmetric Yang-Mills theory for 2 -> 4 particle scattering at two and three loops in the Regge kinematics. We perform an analytic continuation of two-loop result for the remainder function found by Goncharov, Spradlin, Vergu and Volovich to the physical region, where the remainder function does not vanish in the Regge limit. After the continuation both the leading and the subleading in the logarithm of the energy terms are extracted and analyzed. Using this result we calculate the next-to-leading corrections to the impact factors required in the BFKL approach. The BFKL technique was used to find the leading imaginary and real parts of the remainder function at three loops.

Constraining compactness and magnetic field geometry of X-ray pulsars from the statistics of their pulse profiles

description: The light curves observed from X-ray pulsars and magnetars reflect the radiation emission pattern, the geometry of the magnetic field, and the neutron star compactness. We study the statistics of X-ray pulse profiles in order to constrain the neutron star compactness and the magnetic field geometry. We collect the data for 124 X-ray pulsars, which are mainly in high-mass X-ray binary systems, and classify their pulse profiles according to the number of observed peaks seen during one spin period, dividing them into two classes, single- and double-peaked. We find that the pulsars are distributed about equally between both groups. We also compute the probabilities predicted by the theoretical models of two antipodal point-like spots that emit radiation according to the pencil-like emission patterns. These are then compared to the observed fraction of pulsars in the two classes. Assuming a blackbody emission pattern, it is possible to constrain the neutron star compactness if the magnetic dipole has arbitrary inclinations to the pulsar rotational axis. More realistic pencil-beam patterns predict that 79% of the pulsars are double-peaked independently of their compactness. The theoretical predictions can be made consistent with the data if the magnetic dipole inclination to the rotational axis has an upper limit of 40+/-4 deg. We also discuss the effect of limited sensitivity of the X-ray instruments to detect weak pulses, which lowers the number of detected double-peaked profiles and makes the theoretical predictions to be consistent with the data even if the magnetic dipole does have random inclinations. This shows that the statistics of pulse profiles does not allow us to constrain the neutron star compactness. In contrast to the previous claims by Bulik et al. (2003), the data also do not require the magnetic inclination to be confined in a narrow interval.

title: Social and religious determinants of the likelihood of adopting Islamic banking and financial services among Canadian Muslim consumers
Creators: name: Sawwaf, Mohamad M.
Publisher: name: University of Reading
Year: 2023

description: This is the first-known study conducted in Canada on the social and religious determinants of the likelihood of adopting Islamic banking and financial services among Canadian Muslim consumers. Using Structural Equation Modelling, a model was tested based on the Theory of Planned Behaviour. The hypothesized paths in the structural model affecting one's intentions to use Islamic banking and financial services were: positive attitude, higher Islamic religiosity, positive subjective norms, perceived behavioural control, and lower perceived cost of being Muslim. A total of 536 completed surveys from individuals residing in Canada who self-identified as Muslims were obtained. The data were then analyzed using SPSS and AMOS. The model's research hypotheses were tested using a three-step approach: exploratory factor analysis, confirmatory factor analysis, and SEM. The results reveal that attitude was most important, followed by religiosity, subjective norms, and perceived behavioural control. In contrast, the cost of being Muslim had the least bearing on the intention to adopt IBF. This research study is based in Canada and seeks to address the gap in IBF literature in the Canadian and broader North American contexts. While other IBF studies consider religiosity as a construct to determine IBF adoption, this research study extends on this research, adopting a multidimensional construct that explores the impact of belief, experience, rituals, knowledge, devotion, and consequences to identify differences and relationships, if any, between each dimension and the intention to adopt IBF. This study creates a predictive model that may be used to identify not only the intention of the Muslim population in Canada to adopt IBF but, ultimately, assist in developing targeted marketing and business development strategies for IBF for both conventional and Islamic finance institutions. This is a timely study in the Canadian market and broader Western context, and the findings may significantly impact future development and practices.

description: In finance, one usually deals not with prices but with growth rates $R$, defined as the difference in logarithm between two consecutive prices. Here we consider not the trading volume, but rather the volume growth rate $\tilde R$, the difference in logarithm between two consecutive values of trading volume. To this end, we use several methods to analyze the properties of volume changes $|\tilde R|$, and their relationship to price changes $|R|$. We analyze $14,981$ daily recordings of the S\&P 500 index over the 59-year period 1950--2009, and find power-law {\it cross-correlations\/} between $|R|$ and $|\tilde R|$ using detrended cross-correlation analysis (DCCA). We introduce a joint stochastic process that models these cross-correlations. Motivated by the relationship between $| R|$ and $|\tilde R|$, we estimate the tail exponent ${\tildeα}$ of the probability density function $P(|\tilde R|) \sim |\tilde R|^{-1 -\tildeα}$ for both the S\&P 500 index as well as the collection of 1819 constituents of the New York Stock Exchange Composite index on 17 July 2009. As a new method to estimate $\tildeα$, we calculate the time intervals $τ_q$ between events where $\tilde R>q$. We demonstrate that $\barτ_q$, the average of $τ_q$, obeys $\bar τ_q \sim q^{\tildeα}$. We find $\tilde α\approx 3$. Furthermore, by aggregating all $τ_q$ values of 28 global financial indices, we also observe an approximate inverse cubic law.

Electrochemical evaluation and modulation of surface wettability
Creators: name: Kung, Chun Haow
Publisher: name: University of British Columbia
Year: 2018

description: Smart surfaces with dynamic and reversible wettability offer much versatility to meet various application needs. However, application of the smart materials remains challenging, mostly due to complex preparation procedure, a small change in the contact angle, and slow wettability switching. A thorough understanding of wetting phenomena is needed to achieve a breakthrough in the design of superwettability systems. This thesis describes an electrochemical technique to evaluate the surface wettability of rough surfaces based on the wetted area under the droplet. The proportionality between the double layer capacitance and the ion accessible solid-liquid interfacial area is exploited to determine the actual wetted area. While the contact angle fails to describe the wetting mode, the electrochemical approach is capable of discerning the effective wetted area. The electrochemical wettability metric is also used to understand an anomalous wetting behaviour at which the contact angle and interfacial area of an intrinsically hydrophilic substrate show a concurrent increase with roughness. These observations contradict predictions from the Wenzel and Cassie- Baxter models. Based on a coupled optical and electrochemical analysis, the limitations of contact angle are highlighted. An in-situ control over the wettability of electrodeposited copper structure through electrochemical modulation of oxidation state is demonstrated for the first time. Precise control over the rate and extent of the wetting transition is achieved by tuning the magnitude and duration of the applied voltage. Moreover, air drying at room temperature for 1 hour or mild heat drying at 100°C for 30 min restores the initial superhydrophobicity. Microstructural and electrochemical analysis show that the active wetting control is based on the Faradaic phase transformation of the surface-bound CuxO phase shielding the Cu core. Based on the wetting switching functionality of the Cu-CuxO core-shell structures, a smart oil-water membrane is designed. The as-deposited or air-dried Cu mesh exhibits superhydrophobicity and superoleophilicity, thus is effective for heavy oil-water separation. On the other hand, the application of a small reduction voltage (< 1.5 V) remediated light-oil contaminated water. Separation efficiencies greater than 98% are achieved with less than 5% variation over 30 cycles.

Classifying the near-equality of ribbon Schur functions
Creators: name: Tom, Foster
Publisher: name: University of British Columbia
Year: 2018

description: We consider the problem of when the difference of two ribbon Schur functions is a single Schur function. We prove that this near-equality phenomenon occurs in fourteen infinite families and we conjecture that these are the only possible cases. Towards this converse, we prove that under certain additional assumptions the only instances of near-equality are among our fourteen families. In particular, we prove that our first ten families are a complete classification of all cases where the difference of two ribbon Schur functions is a single Schur function whose corresponding partition has at most two parts at least 2. We also provide a framework for interpreting the remaining four families and we explore some ideas towards resolving our conjecture in general. We also determine some necessary conditions for the difference of two ribbon Schur functions to be Schur-positive.

description: We investigate an effective model for organometallic complexes (with potential uses in optoelectronic devices) via both exact diagonalisation and the configuration interaction singles (CIS) approximation. This model captures a number of important features of organometallic complexes, notably the sensitivity of the radiative decay rate to small chemical changes. We find that for large parameter ranges the CIS approximation accurately reproduces the low energy excitations and hence the photophysical properties of the exact solution. This suggests that electronic correlations do \emph{not} play an important role in these complexes. This explains why time-dependent density functional theory works surprisingly well in these complexes.

description: In this paper we outline a Matrix Ansatz approach to some problems of combinatorial enumeration. The idea is that many interesting quantities can be expressed in terms of products of matrices, where the matrices obey certain relations. We illustrate this approach with applications to moments of orthogonal polynomials, permutations, signed permutations, and tableaux.

description: We investigate the asteroseismology of two solar-like targets as observed with the CoRoT satellite, with particular attention paid to the mode fitting. HD 181420 and HD 49933 are typical CoRoT solar-like targets (156 and 60-day runs). The low signal-to-noise ratio (SNR) of about 3-10 prevents us from unambiguously identifying the individual oscillation modes. In particular, convergence problems appear at the edges of the oscillation spectrum. HD 181420 and HD 49933 are typical CoRoT solar-like targets (156 and 60-day runs). The low signal-to-noise ratio (SNR) of about 3-10 prevents us from unambiguously identifying the individual oscillation modes. In particular, convergence problems appear at the edges of the oscillation spectrum. We apply a Bayesian approach to the analysis of these data. We compare the global fitting of the power spectra of this time series, obtained by the classical maximum likelihood (MLE) and the maximum a posteriori (MAP) estimators. We examine the impact of the choice of the priors upon the fitted parameters. We also propose to reduce the number of free parameters in the fitting, by replacing the individual estimate of mode height associated with each overtone by a continuous function of frequency (Gaussian profile). The MAP appears as a powerful tool to constrain the global fits, but it must be used carefully and only with reliable priors. The mode width of the stars increases with the frequency over all the oscillation spectrum.

Polymer translocation into a fluidic channel through a nanopore

subject: FOS: Physical sciences

description: Using two dimensional Langevin dynamics simulations, we investigate the dynamics of polymer translocation into a fluidic channel with diameter $R$ through a nanopore under a driving force $F$. Due to the crowding effect induced by the partially translocated monomers, the translocation dynamics is significantly altered in comparison to an unconfined environment, namely, we observe a nonuniversal dependence of the translocation time $τ$ on the chain length $N$. $τ$ initially decreases rapidly and then saturates with increasing $R$, and a dependence of the scaling exponent $α$ of $τ$ with $N$ on the channel width $R$ is observed. The otherwise inverse linear scaling of $τ$ with $F$ breaks down and we observe a minimum of $α$ as a function of $F$. These behaviors are interpreted in terms of the waiting time of an individual segment passing through the pore during translocation.

Non-equilibrium effects in the magnetic behavior of Co_3O_4 nanoparticles

description: We report detailed studies on non-equilibrium magnetic behavior of antiferromagnetic Co_3O_4 nanoparticles. Temperature and field dependence of magnetization, wait time dependence of magnetic relaxation (aging), memory effects and temperature dependence of specific heat have been investigated to understand the magnetic behavior of these particles. We find that the system shows some features characteristic of nanoparticle magnetism such as bifurcation of field cooled (FC) and zero field cooled (ZFC) susceptibilities and a slow relaxation of magnetization. However, strangely, the temperature at which the ZFC magnetization peaks coincides with the bifurcation temperature and does not shift on application of magnetic fields up to 1 kOe, unlike most other nanoparticle systems. Aging effects in these particles are negligible in both FC and ZFC protocol and memory effects are present only in FC protocol. We estimate the Néel temperature by using Fisher's relation as well as directly by measurement of specific heat, thus testing the validity of Fisher's relation for nanoparticles. We show that Co3O4 nanoparticles constitute a unique aniferromagnetic system which develops a magnetic moment in the paramagnetic state because of antiferromagnetic correlations and enters into a blocked state above the Néel temperature.

description: We investigate the average velocity of Brownian particles driven by a constant external force when constrained to move in two-dimensional, weakly-corrugated channels. We consider both the geometric confinement of the particles between solid walls as well as the soft confinement induced by a periodic potential. Using perturbation methods we show that the leading order correction to the marginal probability distribution of particles in the case of soft confinement is equal to that obtained in the case of geometric confinement, provided that the (configuration) integral over the cross-section of the confining potential is equal to the width of the solid channel. We then calculate the probability distribution and average velocity in the case of a sinusoidal variation in the width of the channels. The reduction on the average velocity is larger in the case of soft channels at small Péclet numbers and for relatively narrow channels and the opposite is true at large Péclet numbers and for wide channels. In the limit of large Péclet numbers the convergence to bulk velocity is faster in the case of soft channels. The leading order correction to the average velocity and marginal probability distribution agree well with Brownian Dynamics simulations for the two types of confinement and over a wide range of Péclet numbers.

description: Gellius toxius n. sp. Sur une vingtaine d'espèces connues du genre Gellius, il n'en était pas, à ma connaissance, une seule jusqu'ici qui ne possédât que des toxes en fait de microsclères. Ridley et Dendy ont en effet constaté que Gellius angulatus Bowerbank avait été décrit par son auteur d'une façon incomplète. Gellius toxius a pour type un petit spécimen blanchâtre et peu consistant, en plaque longue de 10 mm., épaisse de 2, sur un polypier. La surface, lisse en apparence, est en réalité très finement hispide. Les pores s'aperçoivent à travers l'ectosome. La charpente est réticulée, unispiculée, à faibles liens de spongine aux entrecroisements des spicules, nullement comparable en un mot à celle des Toxochalïna. Spiculation. - I. Mégasclères: 1. Oxes, à pointes acérées, courtes, ne se dessinant qu'à une distance des extrémités égale à un diamètre et demi de la tige; longueur 180 fx, épaisseur 9 [t. Il en existe une assez forte proportion de plus grêles, épars dans la chair et dans l'ectosome. II. Microsclères: 2. Toxes à courbure douce, arrondie, et à pointes récurvées. Ils sont très nombreux, mais de taille inégale; en moyenne, ils mesurent 50 ^ d'envergure et 2 jj, d'épaisseur; les plus forts atteignent 90 n de longueur sur 3 y* d'épaisseur au centre.

description: The masses of the heavy tetraquarks with open charm and bottom are calculated within the diquark-antidiquark picture in the framework of the relativistic quark model. The dynamics of the light quarks and diquarks is treated completely relativistically. The diquark structure is taken into account by calculating the diquark-gluon form factor. New experimental data on charmed and charmed-strange mesons are discussed. Our results indicate that the anomalous scalar D_{s0}^*(2317) and axial vector D_{s1}(2460) mesons could not be considered as diquark-antidiquark bound states. On the other hand, D_s(2632) and D_{sJ}^*(2860) could be interpreted as scalar and tensor tetraquarks, respectively. The predictions for masses of the corresponding bottom counterparts of the charmed tetraquarks are given.

description: We review the differences between bubble formation in champagne and other carbonated drinks, and stout beers which contain a mixture of dissolved nitrogen and carbon dioxide. The presence of dissolved nitrogen in stout beers gives them a number of properties of interest to connoisseurs and physicists. These remarkable properties come at a price: stout beers do not foam spontaneously and special technology, such as the widgets used in cans, is needed to promote foaming. Nevertheless the same mechanism, nucleation by gas pockets trapped in cellulose fibres, responsible for foaming in carbonated drinks is active in stout beers, but at an impractically slow rate. This gentle rate of bubble nucleation makes stout beers an excellent model system for the scientific investigation of the nucleation of gas bubbles. The equipment needed is very modest, putting such experiments within reach of undergraduate laboratories. Finally we consider the suggestion that a widget could be constructed by coating the inside of a beer can with cellulose fibres.
