description: As part of a wider study of coherent states in (loop) quantum gravity, we introduce a modification to the standard construction, based on the recently introduced (non-commutative) flux representation. The resulting quantum states have some welcomed features, in particular concerning peakedness properties, when compared to other coherent states in the literature.

Predictors of cancer prevention and early detection counselling beliefs in naturopath and medical trainees : a comparative study
Creators: name: Dale, Laura Chiaranna
Publisher: name: University of British Columbia
Year: 2013

description: Introduction: Research suggests that at least 50% of cancers could be prevented through lifestyle modifications including reductions in tobacco and alcohol, increases in physical activity, weight control, diet improvements, safer sex practices and sun protection (Colditz, Sellers, & Trapido, 2006). The early detection of cancer increases the chance of successful treatment of the disease. Health care providers in both the complementary and alternative medical and biomedical health systems can encourage patients to lead cancer free lifestyles. Health care students develop cancer-counselling beliefs during their training that may influence their future counselling practices. The main purpose of this study is to explore possible differences between naturopath and medical students’ counselling self-efficacy in terms of cancer prevention and early detection. Methods: A cross-sectional research design was employed for this study. Online surveys were administered to assess medical (n=121) and naturopath (n= 121) students’ cancer prevention and early detection beliefs. Univariate and multivariate logistic regression analyses were performed for each independent variable and the outcome variable. Odds ratios were calculated and their 95% confidence intervals were reported. Results: Significantly more naturopath (87%) than medical (45%) students believed that over 50% of cancers could be prevented. Naturopath students (89%) also expected to spend more time (>30 minutes) with their patients than medical students (3%). Naturopath students rated counselling on most cancer prevention and screening practices as more important, and they were more confident in their ability to counsel. Regardless of educational program, if students perceived cancer screening and prevention practices to be more important, they reported higher self-efficacy for counselling. No significant differences between students’ counselling self-efficacy was observed when controlling for educational program and potential confounders. Discussion: With cancer remaining the number one killer of Canadian adults, our future health care professionals must develop positive, evidence-based cancer prevention and early detection beliefs. Many similarities and differences were observed between medical and naturopath students and further investigations should examine the extent to which students’ beliefs predict counselling behaviours. There is a need for increased collaborative, educational research to encourage positive cancer prevention and screening beliefs in medical and naturopath students.

description: This paper deals with an original design of an active power splitter featuring a differential output presenting a greatly enhanced even mode rejection.The proposed circuit consists in two cascaded common emitter and common collector differential pairs.For achieving the best performance,it is shown that each of these two differential pairs requires a specific common node to ground impedance that is discussed.The circuit has been implemented on a 0.25 µm SiGe BiCMOS process and exhibits anticipated phase and amplitude broadband unbalance less than 6.5 ° and 0.6 dB respectively all over the 6 -27 GHz frequency range.At 20 GHz,a common mode rejection ratio better than 43 dB is predicted,i.e.a maximum 0.12 dB /0.35 ° output signal unbalance.

description: In this study we show that the skewness S_3 of the cosmic density field contains a significant and potentially detectable and clean imprint of Baryonic Acoustic Oscillations. Although the BAO signal in the skewness has a lower amplitude than second order measures like the two-point correlation function and power spectrum, it has the advantage of a considerably lower sensitivity to systematic influences. Because it lacks a direct dependence on bias if this concerns simple linear bias, skewness will be considerably less beset by uncertainties due to galaxy bias. Also, it has a weaker sensitivity to redshift distortion effects. We use perturbation theory to evaluate the magnitude of the effect on the volume-average skewness, for various cosmological models. One important finding of our analysis is that the skewness BAO signal occurs at smaller scales than that in second order statistics. For an LCDM spectrum with WMAP7 normalization, the BAO feature has a maximum wiggle amplitude of ~3% and appears at a scale of ~82Mpc/h. We conclude that the detection of BAO wiggles in future extensive galaxy surveys via the skewness of the observed galaxy distribution may provide us with a useful, and potentially advantageous, measure of the nature of Dark Energy.

description: A vast majority of marine geological research is based on academic seismic data collected with single-channel systems or short-offset multichannel seismic cables, which often lack reflection moveout for conventional velocity analysis. Consequently, our understanding of Earth processes often relies on seismic time sections, which hampers quantitative analysis in terms of depth, formation thicknesses, or dip angles of faults. In order to overcome these limitations, we present a robust diffraction extraction scheme that models and adaptively subtracts the reflected wavefield from the data. We use diffractions to estimate insightful wavefront attributes and perform wavefront tomography to obtain laterally resolved seismic velocity information in depth. Using diffraction focusing as a quality control tool, we perform an interpretation-driven refinement to derive a geologically plausible depth-velocity model. In a final step, we perform depth migration to arrive at a spatial reconstruction of the shallow crust. Further, we focus the diffracted wavefield to demonstrate how these diffraction images can be used as physics-guided attribute maps to support the identification of faults and unconformities. We demonstrate the potential of this processing scheme by its application to a seismic line from the Santorini Amorgos Tectonic Zone, located on the Hellenic Volcanic Arc, which is notorious for its catastrophic volcanic eruptions, earthquakes, and tsunamis. The resulting depth image allows a refined fault pattern delineation and, for the first time, a quantitative analysis of the basin stratigraphy. We conclude that diffraction-based data analysis has a high potential, especially when the acquisition geometry of seismic data does not allow conventional velocity analysis.

description: Changes in the properties and dynamics of tidewater glacier systems are key indicators of the state of Arctic climate and environment. Calving of tidewater glacier fronts is currently the dominant form of ice mass loss and a major contributor to global sea-level rise. An important yet under-studied aspect of this process is transformation of Arctic landscapes, where new lands and coastal systems are revealed due to the recession of marine-terminating ice masses. The evolution of those freshly exposed paraglacial coastal environments is controlled by nearshore marine, coastal and terrestrial geomorphic processes, which rework glacial-derived sediments to create new coastal paraglacial landforms and landscapes. Here, we present the first study of the paraglacial coasts of Brepollen, one of the youngest bays of Svalbard revealed by ice retreat. We describe and classify coastal systems and the variety of landforms (deltas, cliffs, tidal flats, beaches) developed along the shores of Brepollen during the last 100 years. We further discuss the main modes of sediment supply to the coast in different parts of the new bay, highlighting the fast rate of coastal transformation as a paraglacial response to rapid deglaciation in the Arctic. This study provides an exemplar of likely coastal responses to be anticipated in similar tidewater settings under future climate change. © 2020 The Authors.

Green smile, interrupted : the frustrated ecological possibilities in Alan Moore's Swamp Thing
Creators: name: Whitford, Alec
Publisher: name: University of British Columbia
Year: 2013

description: In this thesis, I conduct an ecocritical reading of Alan Moore’s tenure as writer on DC Comics’ monthly superhero comic Swamp Thing, which spanned from Volume 2 Issue 20 (January 1984) to Volume 2 Issue 64 (September 1987). I explore the ways in which Swamp Thing’s efforts to understand “the green”—a metaphysical network that connects all plant life in the universe—both challenge and reinforce the classical, Western division between Culture and Nature. Richard Harrison claims that the tenure of each creative team on a superhero comic establishes that tenure as a novel built around a “‘core cluster’ of first principles that define the hero in time and place and set his or her story in motion” (26). Whereas the core cluster of first principles for Wein and Wrightson’s run on Swamp Thing establishes non-human Nature as a physically violent force that unites with violent Culture to produce the monstrous body of Swamp Thing, Moore’s run establishes a core cluster of second principles that posit a more peaceful Nature that is continuously in conflict with the violence of Culture. The primary image of Wein’s first principles is Swamp Thing’s face frozen in an expression of horror and agony, while Moore’s second principles rely on a peaceful, smiling expression on Swamp Thing’s face, which suggests that Swamp Thing’s face is the face of ecology and an icon for the point at which humans can speak to the environment. Wein’s Swamp Thing was the anguished face of the environment, the point at which humans experience the sublime horror of the swamp, but Moore’s Swamp Thing is the smiling face of the environment, the point at which humans are invited to interact with the plants that comprise the swamp. For ecology to be possible in Swamp Thing’s world, humans must engage the smiling face of the environment.
Permeability estimation from induced polarization: an evaluation of geophysical length scales using an effective hydraulic radius concept
Creators: name: Weller, Andreas
name: Slater, Lee
Publisher: name: FID GEO
Year: 2019

description: Geophysical length scales defined from induced-polarization measurements can be used in models of permeability (k) prediction. We explore the relative merit of different induced-polarization parameters as proxies of an effective hydraulic radius (reff) that can be used to predict permeability from a modified Hagen–Poiseuille equation. Whereas geometrical measures of the hydraulic radius are good proxies of reff, the induced-polarization measures are not well correlated with reff. However, a new proxy of reff that considers both imaginary conductivity and formation factor shows an improved correlation with reff. The resulting model enables a better quality of permeability prediction compared with the other geophysical length scales, but does not reach the predictive quality of the models based on geometrical length scales. The specific polarizability defined when incorporating the effect of the formation factor on imaginary conductivity appears to be independent of pore geometry, indicating that it is the correct parameter representing the role of the surface electrochemistry on the induced-polarization effect. However, the joint dependence of induced-polarization measurements on both the pore radius and the tortuosity and porosity of the interconnected pore network is a limitation to the widely explored use of induced-polarization measurements to isolate surface properties from volumetric properties of the interconnected pore network.

description: Active rifts release large amounts of gases from deep sources to the atmosphere by advection and diffusion processes along permeable fracture zones. The objective of this study is to develop geothermal exploration concepts for areas with little or no hydrothermal surface expressions suitable for fluid sampling and analyses (e.g., hot springs, geysers, and fumaroles). In such areas, soil gas surveys can complement established geophysical and geochemical exploration. We report CO2, 222Rn (radon), and 220Rn (thoron) emission data and ground temperatures from the Aluto volcanic complex in the Main Ethiopian Rift to improve understanding of tectonic and volcanic controls on the existing geothermal system. This suite of gas emission measurements allows us to identify major, deep-rooted permeable structures with active fluid circulation and identify suitable drilling targets for geothermal production wells on Aluto. We show that significant differences in gas signatures (i.e., efflux and spatial pattern) can be used to identify predominantly volcanically and/or tectonically influenced compartments. Major gas emissions indicate significant fluid circulation at depth, which is typical for magmatic systems. Such high gas emissions have been observed in areas affected by major tectonic structures interacting with magmatic bodies at depth (tectono-volcanic). Predominantly fault-controlled sectors also show hydrothermal fluid circulation, but to a lower extent compared to tectono-volcanic sectors. Within the Aluto volcanic complex, geothermal production wells mainly target such fault-controlled domains, whereas results of the study indicate strongest fluid circulation in tectono-volcanic sectors. This result should be considered for the future exploration and development strategy of the site.

description: We combine numerical modeling of lithospheric extension with analysis of seismic moment release and earthquake b-value in order to elucidate the mechanism for deep crustal seismicity and seismic swarms in the Main Ethiopian Rift (MER). We run 2-D numerical simulations of lithospheric deformation calibrated by appropriate rheology and extensional history of the MER to simulate migration of deformation from mid-Miocene border faults to ∼30 km wide zone of Pliocene to recent rift floor faults. While currently the highest strain rate is localized in a narrow zone within the rift axis, brittle strain has been accumulated in a wide region of the rift. The magnitude of deviatoric stress shows strong variation with depth. The uppermost crust deforms with maximum stress of 80 MPa, at 8–14 km depth stress sharply decreases to 10 MPa and then increases to a maximum of 160 MPa at ∼18 km depth. These two peaks at which the crust deforms with maximum stress of 80 MPa or above correspond to peaks in the seismic moment release. Correspondingly, the drop in stress at 8–14 km correlates to a low in seismic moment release. At this depth range, the crust is weaker and deformation is mainly accommodated in a ductile manner. We therefore see a good correlation between depths at which the crust is strong and elevated seismic deformation, while regions where the crust is weaker deform more aseismically. Overall, the bimodal depth distribution of seismic moment release is best explained by the rheology of the deforming crust.

description: We propose optical phonon lasing for a double quantum dot (DQD) fabricated in a semiconductor substrate. We show that the DQD is weakly coupled to only two LO phonon modes that act as a natural cavity. The lasing occurs for pumping the DQD via electronic tunneling at rates much higher than the phonon decay rate, whereas an antibunching of phonon emission is observed in the opposite regime of slow tunneling. Both effects disappear with an effective thermalization induced by the Franck-Condon effect in a DQD fabricated in a carbon nanotube with a strong electron-phonon coupling.

description: Forbush decreases (FDs), which are short-term drops in the flux of galactic cosmic rays, are caused by the shielding from strong and/or turbulent magnetic structures in the solar wind, especially interplanetary coronal mass ejections (ICMEs) and their associated shocks, as well as corotating interaction regions. Such events can be observed at Earth, for example, using neutron monitors, and also at many other locations in the solar system, such as on the surface of Mars with the Radiation Assessment Detector instrument onboard Mars Science Laboratory. They are often used as a proxy for detecting the arrival of ICMEs or corotating interaction regions, especially when sufficient in situ solar wind measurements are not available. We compare the properties of FDs observed at Earth and Mars, focusing on events produced by ICMEs. We find that FDs at both locations show a correlation between their total amplitude and the maximum hourly decrease, but with different proportionality factors. We explain this difference using theoretical modeling approaches and suggest that it is related to the size increase of ICMEs, and in particular their sheath regions, en route from Earth to Mars. From the FD data, we can derive the sheath broadening factor to be between about 1.5 and 1.9, agreeing with our theoretical considerations. This factor is also in line with previous measurements of the sheath evolution closer to the Sun.

description: New marine geophysical data acquired across the partly ice-covered northern East Greenland continental margin highlight a complex interaction between tectonic and magmatic events. Breakup-related lava flows are imaged in reflection seismic data as seaward dipping reflectors, which are found to decrease in size both northward and southward from a central point at 75°N. We provide evidence that the magnetic anomaly pattern in the shelf area is related to volcanic phases and not to the presence of oceanic crust. The remnant magnetization of the individual lava flows is used to deduce a relative timing of the emplacement of the volcanic wedges. We find that the seaward dipping reflectors have been emplaced over a period of 2–4 Ma progressively from north to south and from landward to seaward. The new data indicate a major post-middle Eocene magmatic phase around the landward termination of the West Jan Mayen Fracture Zone. This post-40-Ma volcanism likely was associated with the progressive separation of the Jan Mayen microcontinent from East Greenland. The breakup of the Greenland Sea started at several isolated seafloor spreading cells whose location was controlled by rift structures and led to the present-day segmentation of the margin. The original rift basins were subsequently connected by steady-state seafloor spreading that propagated southward, from the Greenland Fracture Zone to the Jan Mayen Fracture Zone.
A HISTORICAL PERSPECTIVE ON THE MISUSE OF POWER IN ORWELL'S ANIMAL FARM

description: It is normal to witness politicians exploiting ordinary people as a result of the leader's poor use of absolute authority and the people's silence. Knowledge and education appear to lead to total power, culminating in the pain and persecution of simple and ignorant people in the Soviet Union. The majority of people do not understand the terminology utilized in Animal Farm, which creates a danger through numerous concepts and rules. This allowed the wealthy to abuse people for their selfish interests and engage in illegal activities. As a result of the use of ambiguous language and the deployment of terror tactics, they were able to persuade others, and then they developed lies in the interests of leaders. However, because of their simplicity, the others were readily persuaded, whereas power could be used to serve the entire people of the Soviet Union. The paper analyzes the research using a historical method.
Performance of thunniform propulsion : a high bio-fidelity experimental study
Creators: name: Delepine, Marc
Publisher: name: University of British Columbia

description: Tunas, lamnid sharks and whales are some of the fastest sustained swimming animals. To propel themselves these animals use the thunniform propulsion mode, and are physically characterized by having streamlined bodies with narrow necking of the caudal peduncle and a high aspect ratio lunate tail generating lift-based thrust. For these reasons, thunniform propulsion has received considerable attention from biologists and bio-inspired engineers. Thunniform propulsion is assumed to have the highest propulsive performance of all swimming modes, meaning high propulsive efficiency at fast swimming speeds. However, there is no direct empirical evidence to support this common idea, due to the difficulty of obtaining force measurements for these animals. Therefore, indirect approaches are used, such as theoretical and experimental studies. But these experiments oversimplify the animal (motion, shape or material property) and/or the flow condition. Our goal was to assess the propulsive performance of the Atlantic bluefin tuna, Thunnus thynnus, which is our case study for thunniform propulsion, by an experimental approach of the highest bio-fidelity currently performed. A computed tomography scanner and a polyjetTM 3-Dimensional printer were used to make three tail models: two with materials of similar properties to the caudal fin, and one of uniform stiffness. Each model was actuated in a water tunnel by a computer controlled, motorized system to follow motion paths typical for a tuna. Propulsive efficiencies and thrust coefficients were calculated from force and torque measurements. Flow structures were visualized by means of particle image velocimetry (PIV). For the 30 motion regimes the mean thrust over a tail-beat was positive. About half of those generated sufficient thrust to counter the whole body drag estimates (CT ≥0.19). Propulsive performance trends and values were similar for all our tail models and to previous experiments investigating a similar parametric space, where the peak propulsive performance was observed for all tail models and hydrofoils at Sttip =0.35 and α_max =20º. The average peak propulsive performance for the tail models was ηp =0.43 and CT =0.3. As with recent studies, we conclude propulsive performance is more sensitive to kinematics rather than the shape and bending behavior of the caudal fin.
A note on the one-dimensional hydrogen atom with minimal length uncertainty

description: We present exact energy spectrum and eigenfunctions of the one-dimensional hydrogen atom in the presence of the minimal length uncertainty. By requiring the self-adjointness property of the Hamiltonian, we completely determine the quantization condition. We indicate that the single-valuedness criteria of the eigenfunctions in non-deformed case is an emergent condition and the semiclassical solutions exactly coincide with the quantum mechanical results. The behavior of the wave functions at the origin in coordinate space and in quasiposition space is discussed finally.

description: The ESD characteristics of GaAs diode are
compared with those of Silicon diode. The ESD diodes are
designed and implemented using GaAs HBT technology and
0.25 um CMOS technology. The differences of ESD
characteristics between GaAs diode and Silicon diode are
investigated, simulated and measured. Because the thermal
characteristics of GaAs are different from those of Silicon,
the ESD characteristics of GaAs device are different from
those of Silicon device.

description: Newly developed GaN technology offers great
potential for military and space, as well as some high
volume applications. The devices are grown on different
substrates (sapphire, silicon and silicon carbide), involving
differences on the performances, price, and technological
complexity. The design of a fully integrated transceiver in
such a technology necessitates great noise performances for
the linear (Low Noise Amplifiers, LNA) and non-linear
(Voltage Controlled Oscillator, VCO) applications. The low
noise figure already published on this technology up to Xband,
associated to the capability to handle high power
levels avoid the integration of a limiter stage that
deteriorates the overall noise figure in conventional
architectures. The low frequency noise performances are
useful both for the technology assessment (maturity’s
indicator) and for the non-linear circuit design (conversion
to phase noise around the carrier). This paper presents the
noise performances of AlGaN/GaN HEMT grown on SiC
substrate. Low frequency noise contributors in the Ohmic
and saturated regime are discussed. Residual phase noise
characterization at 10 GHz correlates the results about the
noise sources involved, and linear high frequency noise
figure measurements are also presented, targeting
respectively VCO and LNA applications.

description: This paper provides a new approach to
evaluate the transistor safe operating area at nominal
operating conditions which has been demonstrated on
MESFET technology. It consists on performing on-state and
off-state accelerated DC step stresses for bias conditions
which can be reached by the Vds and Vgs sweeps in
overdrive conditions. Both on-state and off-state stresses
shown different degradation modes which can be attributed
to the different stress bias conditions. On the one hand, the
on-state stress corresponds to the impact ionization regime
where the drain-gate voltage is considered as an
accelerating factor for the device degradation. On the other
hand, the off-state stress is performed for bias conditions
which correspond to the gate leakage current regime in the
reverse Igs-Vgs characteristics where the drain-gate voltage
and the gate current are considered as an accelerating
factor for the device degradation.

description: We compute the topological entropy of the toric code models in arbitrary dimension at finite temperature. We find that the critical temperatures for the existence of full quantum (classical) topological entropy correspond to the confinement-deconfinement transitions in the corresponding Z_2 gauge theories. This implies that the thermal stability of topological entropy corresponds to the stability of quantum (classical) memory. The implications for the understanding of ergodicity breaking in topological phases are discussed.
