description: We present the discovery of the most distant, dynamically relaxed cool core cluster, SPT-CL J2215-3537 (SPT2215) and its central brightest cluster galaxy (BCG) at z=1.16. Using new X-ray observations, we demonstrate that SPT2215 harbors a strong cool core, with a central cooling time of 200 Myr (at 10 kpc) and a maximal intracluster medium cooling rate of 1900+/-400 Msun/yr. This prodigious cooling may be responsible for fueling extended, star-forming filaments observed in Hubble Space Telescope imaging. Based on new spectrophotometric data, we detect bright [O II] emission in the BCG, implying an unobscured star formation rate (SFR) of 320^{+230}_{-140} Msun/yr. The detection of a weak radio source (2.0+/-0.8 mJy at 0.8 GHz) suggests ongoing feedback from an active galactic nucleus (AGN), though the implied jet power is less than half the cooling luminosity of the hot gas, consistent with cooling overpowering heating. The extreme cooling and SFR of SPT2215 is rare among known cool core clusters, and it is even more remarkable that we observe these at such high redshift, when most clusters are still dynamically disturbed. The high mass of this cluster, coupled with the fact that it is dynamically relaxed with a highly-isolated BCG, suggests that it is an exceptionally rare system that must have formed very rapidly in the early Universe. Combined with the high SFR, SPT2215 may be a high-z analog of the Phoenix cluster, potentially providing insight into the limits of AGN feedback and star formation in the most massive galaxies.

description: Observations of neutral hydrogen can provide a wealth of information about the kinematics of galaxies. To learn more about the large scale structures and accretion processes, the extended environment of galaxies have to be observed. Numerical simulations predict a cosmic web of extended structures and gaseous filaments. To observe the direct vicinity of galaxies, column densities have to be achieved that probe the regime of Lyman limit systems. Typically HI observations are limited to a brightness sensitivity of NHI ~ 10^19 cm-2 but this has to be improved by ~2 orders of magnitude. With the Westerbork Synthesis Radio Telescope (WSRT) we map the galaxy filament connecting the Virgo Cluster with the Local Group. About 1500 square degrees on the sky is surveyed, with Nyquist sampled pointings. By using the WSRT antennas as single dish telescopes instead of the more conventional interferometer we are very sensitive to extended emission. The survey consists of a total of 22,000 pointings and each pointing has been observed for 2 minutes with 14 antennas. We reach a flux sensitivity of 16 mJy beam-1 over 16 km s-1, corresponding to a brightness sensitivity of NHI ~ 3.5 \times 10^16 cm-2 for sources that fill the beam. At a typical distance of 10 Mpc probed by this survey, the beam extent corresponds to about 145 kpc in linear scale. Although the processed data cubes are affected by confusion due to the very large beam size, we can identify most of the galaxies that have been observed in HIPASS. Furthermore we made 20 new candidate detections of neutral hydrogen. Several of the candidate detections can be linked to an optical counterpart. The majority of the features however do not show any signs of stellar emission. Their origin is investigated further with accompanying HI surveys which will be published in follow up papers.

Metamorphoses of snake women, Melusine and Madam White
Creators: name: Zhao, Zifeng
Publisher: name: University of British Columbia
Year: 2015

description: By comparing the European literary character Melusine with her Chinese counterpart Madam White, my thesis aims to demonstrate that the metamorphosis of females into snakes is presented in both myths as the literary reproduction of the social and historical process whereby men’s power oppressed women’s. The serpentine metamorphosis will be argued to have a mechanism, which consists of three key elements, namely a specific date, religious context, and forced metamorphosis. To do this, first, I will explore the symbolism of snakes in central European and far eastern Asian traditions. Second, in a close reading, I will analyze and compare the negative impact of serpentine metamorphoses of Melusine and Madam White in their stories. Finally, by addressing the connection to real-life contexts (social, cultural and religious) in the development of these characters, I will provide new insights into the role and status of women in China and German-speaking Europe since early modern times as well as the possible roots of their image as femmes fatales in modern literature.
Physical habitat below a hydropeaking dam : examining progressive downstream change
Creators: name: Winterhalt, Lesley Marie
Publisher: name: University of British Columbia
Year: 2015

description: This study examines the short-term physical habitat conditions at four sites on the Kananaskis River, Alberta, where a hydropeaking dam was installed in 1955. This dam imposes both the approximate pre-dam minimum flow, and the pre-dam flood (from a small flood year) on a daily basis. The purpose of this study was to examine the extent of daily changes in physical habitat conditions that organisms in the stream would have to endure, and the extent to which these fluctuations might be reduced downstream due to distance from the dam and unregulated tributary influence. Physical habitat conditions monitored over low flow and high flow dam releases were: velocity; depth; bed mobility; ramping rates; and total suspended solids. River2D was used to calculate weighted usable area and potential habitat for Brown Trout (fry, juveniles and adults) and Mountain Whitefish (fry, juveniles and adults) at the low and high flow conditions. Of the factors examined, only ramping rates and total suspended solids showed signs of downstream attenuation. Differences in depth, velocity, weighted usable area, and potential habitat between low flow and high flow dam releases were variable, and showed no downstream pattern. Between low and high flow releases, significant (p = 0.05) changes in depth were observed at all sites, and significant changes (p = 0.05) in velocity were observed at all but the second site. The second site also saw the smallest changes in measures of habitat between low flow and high flow dam releases; however, all other sites saw median differences of 48.1% to 170.9%. Percent differences in habitat between low and high flow dam releases ranged from 2.6% (second downstream site, juvenile Brown Trout) to 193.3% (third downstream site, adult Mountain Whitefish). These habitat changes happen more often than before the dam was installed (many times weekly vs. about once a year during the spring freshet) and they occur more rapidly. Because these changes happen at times of the year that are out of synchronization with the biota of the river, and as these changes are extreme, this implies challenging physical habitat conditions for indigenous stream biota.

description: Context: Recently, Doroshenko and collaborators reported a very low-mass compact star, a Central Compact Object named XMMU J173203.3-344518 inside the supernova remnant HESS J1731-347. Its tiny mass is at odds with all calculations of minimum masses of neutron stars generated by iron cores, therefore (and even if not compellingly) it has been suggested to be a {\it strange star}. Besides the mass, a radius and surface temperature have been extracted from data, and the whole body of information should ultimately reveal if this object is truly consistent with an exotic composition. Aims: To understand the status of the compact object XMMU J173203.3-344518 in HESS J1731-347 within the existing models of strange stars, including its prompt formation. Methods: The information obtained on the mass, radius and surface temperature are compared to theoretical calculations performed within usual theoretical models using General Relativity as the assumed theory of gravitation and a handful of cooling scenarios. A qualitative discussion showing the consistency of the strange-matter driven supernova scenario with a low-mass compact star is provided. Results: We found that the object HESS J1731-347 fits within the same quark star models recently employed to explain the masses and radii of the NICER objects PSR J040+6620 and PSR J0030+0451, in which both quantities were simultaneously determined. It is also remarkable to find that a simple cooling scenario devised $30\text{ yr}$ ago with superconducting quarks provides an overall good explanation of the surface temperature. Conclusions: We conclude that XMMU J173203.3-344518 in the remnant HESS J1731-347 fits into a ``strange star'' scenario that is also consistent with heavier compact stars, which can also belong to the same class and constitute an homogeneous type of self-bound objects produced in Nature.

description: In the large N_c limit, some apparently different gauge theories turn out to be equivalent due to large N_c orbifold equivalence. We use effective field theory techniques to explore orbifold equivalence, focusing on the specific case of a recently discovered relation between an SO(2N_c) gauge theory and QCD. The equivalence to QCD has been argued to hold at finite baryon chemical potential, μ_B, so long as one deforms the SO(2N_c) theory by certain "double-trace" terms. The deformed SO(2N_c) theory can be studied without a sign problem in the chiral limit, in contrast to SU(N_c) QCD at finite μ_B. The purpose of the double-trace deformation in the SO(2N_c) theory is to prevent baryon number symmetry from breaking spontaneously at finite density, which is necessary for the equivalence to large N_c QCD to be valid. The effective field theory analysis presented here clarifies the physical significance of double-trace deformations, and strongly supports the proposed equivalence between the deformed SO(2N_c) theory and large N_c QCD at finite density.

description: The scaling of magnetic fluctuations provides crucial information for the understanding of solar wind turbulence. However, the observed magnetic fluctuations contain not only turbulence but also magnetic structures, leading to the violation of the time stationarity. This violation would conceal the true scaling and influence the determination of the sampling angle with respect to the local background magnetic field. Here, to investigate the scaling anisotropy, we utilize an easy but effective criterion $ϕ<10^\circ$ to ensure the time stationarity of the magnetic field, where $ϕ$ is the angle between the two averaged magnetic fields after cutting the interval into two halves. We study the scaling anisotropy using higher-order statistics of structure functions under the condition of stationarity for the near-Sun solar wind turbulence for the first time based on measurements obtained from Parker Solar Probe (PSP) at 0.17 au. We find that the scaling indices $ξ$ of magnetic field show a linear dependence on the order $p$ close to $ξ(p)=p/4$. The multifractal scaling of magnetic-trace structure functions becomes monoscaling close to $ξ(p)=p/3$ with the local magnetic field perpendicular to the sampling direction and close to $ξ(p)=p/4$ with the local magnetic field parallel to the sampling direction when measured with the stationary background magnetic field. The scaling of velocity-trace structure functions has similar but less significant changes. The near-Sun solar wind turbulence displays different scaling anisotropies with the near-Earth solar wind turbulence, suggesting the evolution of the nonlinear interaction process during the solar wind expansion.

Statistical methods for relating strength properties of dimensional lumber
Creators: name: Cai, Yanling
Publisher: name: University of British Columbia
Year: 2015

description: We present a novel approach for predicting one lumber strength property from another, each being measured destructively. The objective is to reduce the cost of lumber monitoring programs, by measuring one of the properties and predicting the other. To reach the objective, we review single proof load design (SPLD) proposed to assess dependence between two jointly normally distributed random variables X and Y that cannot be observed simultaneously. The SPLD tests specimens in one mode X up to a determined load (proof loading), and the survivors are tested to failure in a second mode Y. To resolve the near non--identifiability of parameters in the SPLD approach, we construct a penalty function based on a Bayesian power prior to regularize the parameters. Simulation studies of the penalized approach suggest redesigning the SPLD for improving the estimation performance. The new design, a rediscovery, assigns specimens to one of the two groups: SPLD and shoulder. The shoulder group tests specimens to failure in the Y mode. The SPLD with a shoulder approach results in a more accurate and precise estimate. To quantify damage caused by proof loading lumber specimens, we use the maximum likelihood method to estimate theoretical quantiles of the strength distribution using a sample from a SPLD with a shoulder experiment with a low proof load level. The comparison between those estimated theoretical quantiles and empirical quantiles of the proof load survivors reveals the damage at higher proof load levels. Using our experimental data on manufactured lumber, we find low and high proof load levels leave survivors undamaged, but intermediate load levels do damage weaker survivors. We generalize the SPLD with a shoulder approach to incorporate proof load damage, and thus finally provide a method for estimating the X-Y dependence when damage occurs. This generalized approach is applied on our experimental data to estimate the relationship between bending and log--transformed tension. The high correlation found in our application suggests that if there is a need to verify the two strength properties, only one of them needs to be measured and the other is predicted from the measured strength.
The tensile properties and toughness of microstructures relevant to the HAZ of X80 linepipe steel girth welds
Creators: name: Gaudet, Michael J.
Publisher: name: University of British Columbia
Year: 2015

description: In the transportation of oil and gas products from and over remote locations, such as Canada's Arctic environment, pipelines are used. Girth welding to join sections of steel pipelines creates a substantial heat affected zone (HAZ) within the base pipeline steel. While there is significant concern as to the fracture and mechanical properties of the HAZ as whole, detailed knowledge about the mechanical properties of the microstructural constituents is lacking. For this research, measurements of the temperature time profile in the HAZ of single and dual torch welds were made. This was then used to guide heat treatments of X80 steel in a Gleeble simulator to create samples of 8 different bulk microstructures with differing amounts and morphologies of bainite, ferrite and martensite-retained austenite (MA). From the heat treated samples tensile and Kahn tear test specimens were made for testing at ambient, -20⁰C, and -60⁰C. The highest strength microstructure proved to be the finest, lower bainitic microstructure, while the lowest strength microstructure was the coarsest, upper bainitic sample containing a significant amount of MA. This was observed to be true at all testing temperatures. As part of the tensile behaviour investigation, the Bouaziz dislocation based model for work hardening was applied and shown to fit well across all temperatures and conditions. The Kahn tear test, a machine notched, thin-sheet, slow strain rate test, showed all tests failed in a ductile manner. Relative toughness measurement from this test showed that the fine, lower bainitic microstructure was the toughest and the coarse, ferritic microstructure was the least tough. This work presents a novel measurement of dual torch temperature time profiles in a real HAZ, an extensive mechanical testing program of isolated microstructures relevant to the X80 HAZ at potential pipeline operating temperatures, and an applied a robust model to fit the work hardening behaviour for all conditions. This work has the potential for future application in microstructure evolution-property models, and in a combined mechanical model of the different microstructures to further improve understanding of HAZ mechanical responses.

description: We consider optimization of phase response curves for stochastic synchronization of non-interacting limit-cycle oscillators by common Poisson impulsive signals. The optimal functional shape for sufficiently weak signals is sinusoidal, but can differ for stronger signals. By solving the Euler-Lagrange equation associated with the minimization of the Lyapunov exponent characterizing synchronization efficiency, the optimal phase response curve is obtained. We show that the optimal shape mutates from a sinusoid to a sawtooth as the constraint on its squared amplitude is varied.

description: We report on multi-bands VLBA polarimetric observations of NRAO 530 in February 1997. Total intensity, EVPA distributions at all these frequencies are presented. Model fitting has been performed, from which the fitted southmost component A is confirmed as the core of the radio structure with relatively high brightness temperature and hard spectrum between 15 and 43 GHz in comparison with the central component B of dominant flux. The relatively high degree of polarization for the component A may arise from its complex radio structure, which is resolvable at 86 GHz. As a contrast, the component B shows a well fitted power-law spectrum with the spectral index of about -0.5, and a linear correlation between EVPAs and wavelength square with the observed RM of about -1062 rad m^{-2}, indicating its structural singleness. Assuming that the component B has a comparable degree of polarization without depolarization at these frequencies, the decrease in fractional polarization with wavelength mainly results from opacity and Faraday rotation, in which the opacity plays quite a large part of role. A spine-sheath like structure in fractional polarization is detected covering almost the whole emission region at 5 and 8 GHz. The linear polarization at 5 GHz shows 3 separate polarized emission regions with alternately aligned and orthogonal polarization vectors down the jet. The polarization goes to zero between the top two regions, with the highest polarization level occurring at the top and bottom. The 5 and 8 GHz images show EVPA changes across the width of the jet as well as along the jet. These complex polarimetric properties can be explained in terms of either the presence of a large helical magnetic field or tangled magnetic fields compressed and sheared down the jet.

Romantic descent : poetry and the aesthetics of disappointment, 1790-1820
Creators: name: Mathes, Carmen Faye
Publisher: name: University of British Columbia
Year: 2023

description: Romantic Descent investigates disappointment as a minor, or non-cathartic, critical and aesthetic category in Romantic poetry and prose. Major aesthetic categories, long a focus of Romantic scholarship, have been understood to affirm individual self-cultivation and communal praxes of meaningful progress. However, recent work on affect has theorized alternative models for embodiment and relationality that have allowed new, radical and material, approaches to aesthetic phenomena. My dissertation critically intervenes in these developments by reconsidering Romanticism through its experimentation with disappointment as a negative aesthetic, and in so doing reveals a Romantic poetics of adjustment after the loss of an attachment to a self-affirming outcome or ideal future. Rather than start anew, such a poetics compels readers to persevere in encounters with difficulty, asking them to strive and struggle in ways both socially oriented and radically negative. Through close readings of eighteenth- and early nineteenth-century philosophy, poetry, letters, and the occasional novel, this dissertation traces writers’ mobilizations and responses to aesthetic disappointment in myriad formal and conceptual ways: falling figures (allegory and metaphor); structural recursion (repetition and tautology); metrical irregularities (what Coleridge calls “downfalls”); and stilted or bathetic stylistic conventions. Such “descents” I situate in light of significant intellectual, social and political changes occurring in the period, including British and German responses to the revolutions in France and Haiti; changing cultures of reading; the tensions between philosophical skepticism and the Swabian educational system; and stylistic developments in Romantic theatre. As these contexts suggest, aesthetic activations of disappointment emerge on scales both national and coterie, and what is at stake in this dissertation are the diverse and unexplored affective relations captured but not quite contained by these writings. From Wordsworth’s sympathetic sinking alongside the suffering of slaves; to Coleridge’s projection of reading irregular meter as proprioceptive loss; Hölderlin’s calculated formal downturns; Keats’s affective reciprocity; and finally, Austen’s ironic censure of interrupted novel readers, this dissertation reveals how the critical and aesthetic category of disappointment responds to the dissonant sense between hope and fear, striving and failure, movement and suspension, that permeates Romantic literature.

description: We present, theoretically and experimentally, amorphous photonic lattices exhibiting a band-gap yet completely lacking Bragg diffraction: 2D waveguides distributed randomly according to a liquid-like model responsible for the absence of Bragg peaks as opposed to ordered lattices containing disorder, which always exhibit Bragg peaks. In amorphous lattices the bands are comprised of localized states, but we find that defect states residing in the gap are more localized than the Anderson localization length. Finally, we show how the concept of effective mass carries over to amorphous lattices.

description: Cooperative effects such as super- and subradiance can be observed in the fluorescence emitted by a system of N atoms in vacuum, after interaction with a laser beam. In the vicinity of a dielectric or metallic surface, Casimir-Polder effects can modify collective atomic frequency shifts and decay rates. In this work, we study cooperative fluorescent emission next to resonant surfaces using the coupled dipoles model. We show that cooperative effects, expected in free space, are absent when the atoms are close to a surface whose polariton resonances coincide with the dominant atomic dipole coupling. In this case, cooperative effects are overshadowed by the very fast decay of the atomic fluorescence into surface modes. We illustrate our formalism and our results by considering a line of cesium 6D3/2 atoms in front of a sapphire surface. Finally, we propose the study of Cesium 6P3/2 atoms in front of a resonant metasurface as the most promising scenario for experimentally demonstrating the results of our study.

description: Students in introductory physics courses struggle to understand virtual image formation by a plane mirror and the proper construction of ray diagrams. This difficulty, if not sufficiently addressed, results in further problems throughout the study of geometric optics. Specifically, students fail to apply proper graphical representation of light rays during investigations of the formation of real images by converging lenses and concave mirrors. We present a guided-inquiry activity based on the research-verified Physics by Inquiry text that incorporates a small and inexpensive billiards table, with billiard balls acting as "light". In this way, we approach the abstract concept of virtual images by relation to the concrete concept of physical reflection.

Lyman alpha emission from the first galaxies: Implications of UV backgrounds and the formation of molecules

description: The Lyman alpha line is a robust tracer of high redshift galaxies. We present estimates of Lyman alpha emission from a protogalactic halo illuminated by UV background radiation fields with various intensities. For this purpose, we performed cosmological hydrodynamics simulations with the adaptive mesh refinement code FLASH, including a detailed network for primordial chemistry,comprising the formation of primordial molecules, a multi-level model for the hydrogen atom as well as the photo-ionization and photo-dissociation processes in a UV background. We find that the presence of a background radiation field J_21 excites the emission of Lyman alpha photons, increasing the Lyman alpha luminosity up to two orders of magnitude. For a halo of \sim 10^10 M_sun, we find that a maximum flux of 5 \times 10^-15 erg cm^-2 s^-1 is obtained for J21 \times f_esc = 0.1, where f_esc is the escape fraction of the ionizing radiation. Depending on the environmental conditions, the flux may vary by three orders of magnitude. For J_21 \times f_esc > 0.1 the Lyman alpha luminosity decreases as the atomic hydrogen abundance becomes rather small. The fluxes derived here can be probed using Subaru and the upcoming James Webb Space Telescope. The emission of Lyman alpha photons is extended and comes from the envelope of the halo rather than its core. In the center of the halo, line trapping becomes effective above columns of 10^22 cm^-2 and suppresses the emission of Lyman alpha. In addition, cooling by primordial molecules may decrease the gas temperature in the central region, which further reduces Lyman alpha emission. In the central core, H_2 is photo-dissociated for a background flux of J_21 \geq 1000. For weaker radiation fields, i.e. J_21 < 0.1, H_2 and HD cooling are particularly strong in the center of the halo, leading to gas temperatures as low as \sim 100 K.

description: Aims: We provide new insights into the gamma-ray emission from HESS J1912+101, a TeV supernova remnant candidate probably associated with the radio pulsar PSR J1913+1011. Methods: We obtained new observations at 1.5 GHz using the VLA in the D configuration, with the purpose of detecting the radio shell of the putative remnant. In addition, we observed a single pointing at 6.0 GHz toward PSR J1913+1011 to look for a radio pulsar wind nebula. We also studied the properties of the surrounding interstellar medium using data of the 13CO, HI, and infrared emissions, obtained from public surveys. Results: We did not find evidence of a radio shell down to the sensitivity of the new image at 1.5 GHz. We detect faint diffuse emission around PSR J1913+1011 at 6.0 GHz, which could represent a radio pulsar wind nebula powered by the pulsar. We find dense ambient gas at 60 km/s, which shows a good spatial correspondence with the TeV emission only in the western and eastern directions. There is also dense gas near the center of HESS J1912+101, where the TeV emission is weak. Using infrared data, we identify an active star-forming region in the western part of the shell. Conclusions: Based on the poor spatial match between the ambient gas and the TeV emission (which shows a good correlation in the western and eastern directions and an anticorrelation in the other directions), we conclude that the hadronic mechanism alone does not give a satisfactory explanation of the gamma rays from HESS J1912+101. Additional contributions may come from leptonic processes in the shell of the supernova remnant, together with contributions from PSR J1913$+$1011 and its pulsar wind nebula and/or from the star-forming region. A confident determination of the distance to the putative remnant is necessary to determine whether these sources are associated or just appear superimposed in the line of sight.

Clients' experience of counselling that integrates yoga : a phenomenological inquiry
Creators: name: Beveridge, Samantha
Publisher: name: University of British Columbia

description: Yoga is a mind-body practice that is widely practiced in North America and has demonstrated physical, mental, and emotional benefits, many of which overlap with the benefits of counselling and psychotherapy. Yoga postures, philosophy, breathing, and meditative practices have begun to be used within the counselling paradigm. However, little research has been done on the use and integration of yoga in counselling. This study explored the experience of clients who engaged in counselling that included yoga. Descriptive phenomenology was used to gain a rich understanding of the common essential features of the phenomenon from the participants’ descriptions of their lived experience. Participants included six clients of counselling that integrated yoga (i.e., the use and inclusion of mindful awareness, breath, and bodywork with verbal processing). In-depth interviews and two follow-up member checks were conducted with each participant. Essential themes that emerged include: (1) yoga components: breath, bodywork, body awareness, and mindfulness; (2) counselling component: curious, nonjudgmental verbal processing; (3) integration and transition between components; (4) yoga facilitates processing and regulation; (5) counsellor qualities matter; and (6) this therapy as a whole person, whole life approach. This study contributes to the understanding of this holistic psychotherapy from the client perspective, which gives clients, counsellors, and researchers greater insight and awareness into this emerging integrative practice. Implications for future research and practice in counselling psychology are discussed.

description: Целью данной статьи является исследование основных тенденций управления цифровизацией в Российской Федерации. В статье представлены результаты обзора и анализа основных тенденций управления цифровизацией. Оценен фактический характер влияния интенсивности развития цифровой экономики в РФ на динамику среднего уровня инновационной активности и рентабельности производства продукции, работ, услуг. Охарактеризованы особенности развития основных моделей управления интеграцией организаций в современную цифровую экономику в рамках систем менеджмента отечественных компаний. На основании экономико-статистического анализа оценен характер влияния доли цифровой экономики в ВВП РФ на динамику среднего уровня рентабельности и инновационной активности в национальной экономике в 2012-2019 гг. Систематизированы основные особенности реализации моделей интеграции компаний в структуру цифровой экономики в современной Российской Федерации. Как продемонстрировал экономико-статистический анализ, интенсивное развитие цифровой экономики в 2012 - 2019 гг. не оказывало значимого влияния на средний уровень рентабельности отечественных компаний, что свидетельствует о недостаточной эффективности процессов управления интеграцией субъектов хозяйствования РФ в структуру цифровой экономики. Выявленная тенденция свидетельствует о недостаточно полном использовании экономического потенциала цифровой экономики в системе инновационного менеджмента отечественных организаций различного профиля.

description: In this paper, a new method for handwritten signature identification based on rotated complex wavelet filters is proposed. We have proposed to use the rotated complex wavelet filters (RCWF) and dual tree complex wavelet transform(DTCWT) together to derive signature feature extraction, which captures information in twelve different directions. In identification phase, Canberra distance measure is used. The proposed method is compared with discrete wavelet transform (DWT). From experimental results it is found that signature identification rate of proposed method is superior over DWT

Microstructural evolution in the HAZ of X80 linepipe steel : Phase Field Modelling
Creators: name: Toloui, Morteza
Publisher: name: University of British Columbia
Year: 2015

description: During welding, the heat affected zone (HAZ) of X80 linepipe steel is subjected to very steep spatial variations in temperature and concentration of Nb bearing particles which results in a strongly graded microstructure. Therefore, models on the length scale of the microstructure, i.e. the so-called mesoscale, are useful to simulate microstructure evolution in the HAZ. Among mesoscale models, phase field modelling (PFM) is selected because it is based on diffusional time steps and it is a robust tool to capture complex morphologies, e.g. bainitic ferrite. A PFM is developed for austenite grain growth in 2D and 3D that is applicable to rapid heat-treatment cycles taking the pinning/dissolution effects of Nb bearing particles into account by using an effective mobility concept. In addition, a PFM is developed for the austenite decomposition to predict the simultaneous formation of polygonal ferrite and bainite. PFM is coupled with a carbon diffusion model and an effective interface mobility is introduced to implicitly account for the solute drag effect of Nb. For simplicity, the formation of carbide-free bainite is considered and a suitable anisotropy approach is proposed for the austenite-bainite interface mobility. The model is first applied to a TRIP steel in which ferrite and bainite form separately, and bainite can be considered carbide-free bainite. Then the model is applied to simulate the microstructural evolution in the HAZ of the X80 linepipe steel accounting for the thermal and microstructural gradients and validated with microstructure observations made in a weld trial.

description: Despite the unprecedented performance of deep neural networks (DNNs) in computer vision, their practical application in the diagnosis and prognosis of cancer using medical imaging has been limited. One of the critical challenges for integrating diagnostic DNNs into radiological and oncological applications is their lack of interpretability, preventing clinicians from understanding the model predictions. Therefore, we study and propose the integration of expert-derived radiomics and DNN-predicted biomarkers in interpretable classifiers which we call ConRad, for computerized tomography (CT) scans of lung cancer. Importantly, the tumor biomarkers are predicted from a concept bottleneck model (CBM) such that once trained, our ConRad models do not require labor-intensive and time-consuming biomarkers. In our evaluation and practical application, the only input to ConRad is a segmented CT scan. The proposed model is compared to convolutional neural networks (CNNs) which act as a black box classifier. We further investigated and evaluated all combinations of radiomics, predicted biomarkers and CNN features in five different classifiers. We found the ConRad models using non-linear SVM and the logistic regression with the Lasso outperform others in five-fold cross-validation, although we highlight that interpretability of ConRad is its primary advantage. The Lasso is used for feature selection, which substantially reduces the number of non-zero weights while increasing the accuracy. Overall, the proposed ConRad model combines CBM-derived biomarkers and radiomics features in an interpretable ML model which perform excellently for the lung nodule malignancy classification.
Efficient generation of axial magnetic field by multiple laser beams with twisted pointing directions

description: Strong laser-driven magnetic fields are crucial for high-energy-density physics and laboratory astrophysics research, but generation of axial multi-kT fields remains a challenge. The difficulty comes from the inability of a conventional linearly polarized laser beam to induce the required azimuthal current or, equivalently, angular momentum (AM). We show that several laser beams can overcome this difficulty. Our three-dimensional kinetic simulations demonstrate that a twist in their pointing directions {enables them to carry orbital AM and transfer it to the plasma, thus generating a hot electron population carrying AM needed to sustain the magnetic field.} The resulting multi-kT field occupies a volume that is tens of thousands of cubic microns and it persists on a ps time scale. The mechanism can be realized for a wide range of laser intensities and pulse durations. Our scheme is well-suited for implementation using {multi-kJ PW-class lasers, because, by design, they have multiple beamlets and because the scheme requires only linear-polarization.
