description: Superactivation is the property that two channels with zero quantum capacity can be used together to yield positive capacity. Here we demonstrate that this effect exists for a wide class of inequivalent channels, none of which can simulate each other. We also consider the case where one of two zero capacity channels are applied, but the sender is ignorant of which one is applied. We find examples where the greater the entropy of mixing of the channels, the greater the lower bound for the capacity. Finally, we show that the effect of superactivation is rather generic by providing example of superactivation using the depolarizing channel.

Fast motion estimation methods for H.264 video coding on mobile devices
Creators: name: Von Dem Knesebeck, Matthias
Publisher: name: University of British Columbia
Year: 2010

description: Digital video is becoming an increasingly widespread application on a multitude of devices ranging from mobile devices to digital cinema. Technological advancements in processing speed and available bandwidth along with substantial improvements in compression techniques enable completely new applications and services for digital video content. The most demanding task in video encoding is the motion estimation process which aims to identify similarities to previously transmitted video frames. Up to 90% of the processing requirements are attributable to this element. In this thesis, we present three methods for encoding new and transcoding existing video content with significantly reduced computational complexity while maintaining both quality and bitrate. The first method reduces the number of steps required to perform motion estimation by adaptively adjusting the search accuracy needed in distortion measurement. The second method addresses the topic of mode decision in video encoding and provides an algorithm that allows an early decision about the most probable modes without the need to evaluate all 259 different combinations of block sizes. The third method provides a multi-dimensional measure that facilitates evaluating only the most likely modes for efficiently transcoding existing pre-encoded content to lower resolutions with an arbitrary downscaling ratio. This is an important factor for the ever-growing number of devices and application scenarios that access existing pre-encoded content. Our method supplements existing fast transcoding schemes that primarily focus on efficiently determining motion vectors in transcoding.

description: Introduction:
 Thyroid nodule has 5-10% malignancy rate in Malaysia. TIRADS 3 and 4A category patients pose a challenge in terms of managing conservatively or surgically. This study aims to investigate the malignancy rates and outcomes of patients who have undergone elective thyroid surgery. Method:
 A cross-sectional study was performed using medical records of adult patients (age ≥18 years old ) who have undergone elective thyroid surgery from 1st January 2015 to 31st December 2020. Result:
 94 patients fulfilled the inclusion criteria, with TIRADS 3, n=43 and TIRADS 4A, n=51. Mean size of thyroid nodule for TIRADS 3 is 3.66 +/- 1.35cm, TIRADS 4 is 3.71+/- 1.86. 90% underwent FNAC procedure,and 46.8% went through at least 2 times of FNAC. 61% underwent hemi-thyroidectomy, with 70% indicated for suspicion of malignancy. Tirads 3 recorded 5.4% of malignancy in low BETHESDA category (1-3), 16.7% in high BETHESDA category (4-6), p value 0.315. TIRADS 4A reported 9.3% vs 62.5% malignancy rates, in low vs high BETHESDA category, p value 0.001. Recurrent laryngeal nerve injury (RLNI) and haematoma were the highest post-operative complications recorded for TIRADS 3; for TIRADS 4A, it was hypocalcemia and RLNI. Discussion:
 Both TIRADS 3 and TIRADS 4A recorded low rates of malignancy (5.3% vs 9.3%) with low BETHESDA score (1-3). Molecular testing of FNAC samples and radionuclide scan should be considered prior to surgery in TIRADS 3. Conclusion:
 Malignancy rates are 7% in TIRADS 3, 17.6% in TIRADS 4A. RNI and hypocalcemia are common complications. Disclaimer: Abstract text might vary slightly from what is displayed in the e-poster.

Moving liquids with light: Photoelectrowetting on semiconductors

description: Liquid transport in microchip-based systems is important in many areas such as Laboratory-on-a-chip, Microfluidics and Optofluidics. Actuation of liquids in such systems is usually achieved using either mechanical displacement11 or via energy conversion e.g. electrowetting which modifies wetting. However, at the moment there is no clear way of actuating a liquid using light. Here, by linking semiconductor physics and wetting phenomenon a brand new effect "photoelectrowetting" is demonstrated for a droplet of conducting liquid resting on an insulator-semiconductor stack. Optical generation of carriers in the space-charge region of the underlying semiconductor alters the capacitance of the insulator-semiconductor stack; the result of this is a modification of the wetting contact angle of the droplet upon illumination. The effect is demonstrated using commercial silicon wafers, both n- and p-type having a doping range spanning four orders of magnitude (6\times1014-8\times1018 cm-3), coated with a commercial fluoropolymer insulating film (Teflon\textregistered). Impedance measurements confirm that the observations are semiconductor space-charge related effects. The impact of the work could lead to new silicon-based technologies in the above mentioned areas.

description: Normal schools in 1930s Alberta prepared the province’s future teachers. Several hundred students entered normal schools in Calgary, Camrose, and Edmonton every year to complete the one-year teacher preparation course. Student life in normal schools revolved around relationships between faculty and students. Normal school faculty regulated behaviour in and out of the classroom, supervised extracurricular activities, and oversaw off-campus accommodations in fulfilment of academic and social responsibilities to care for students. They aimed to prepare Normalites (as students called themselves) for the teaching profession and so reinforced existing gender and social mores—expectations to which students were largely content to conform. From the perspective of students, faculty were to be respected because of their power over teacher certification and because they demonstrated genuine care for student wellbeing. Faculty involvement in student affairs, more than any other factor, determined the character and course of student experience at Alberta’s normal schools.

description: In this constructivist grounded theory study, I examine the experiences of nine adult men who graduated from the faith-based drug treatment program Teen Challenge Alberta. Each of the men had been in the program for at least 12-18 months, and each of them had unique life-changing experiences there. As they described hundreds of facets of the program, I noted four basic elements that, together, helped each man change his life and achieve his goals: the structure of the program, his relationships with others, his experiences of God, and his individual initiative to make changes. Those elements helped each gain a new perspective and take on new values that gave purpose and meaning to his life. The men translated their new values into action by living their lives in a different way: helping others and becoming role-models. Their comments about their experiences suggest that Teen Challenge Alberta goes beyond treating drug addiction. It concentrates on shaping a man’s character, which leads to many different outcomes, only one of which is recovery from substance abuse.

description: We have considered the propagation process of the phase-matched array of singular beams through a uniaxial crystal. We have revealed that local beams in the array are rotated when propagating. However the right and left rotations are unequal. There are at least two processes responsible for the array rotation: the interference of local beams and the spatial depolarization. The interference takes place in the vortex birth and annihilation events forming the symmetrical part of the rotation. The depolarization process contributes to the asymmetry of the rotation that is called the rotational spin Hall effect. It can be brought to light due to the difference between the envelopes of the dependences of the angular displacement on the inclination angle of the local beams or the crystal length reaching the value some angular degree. The direction of the additional array rotation is exclusively defined by the handedness of the circular polarization in the initial beam array.

description: The aim of this thesis is to use digital rock physics for understanding flow through porous media. Pore-scale simulations were conducted using the Finite Volume method to solve the Navier-Stokes equations, and the Volume of Fluid method for capturing interface. A workflow is provided, in which primary drainage simulations are performed in order to establish initial water saturation. Then, secondary imbibition simulations are performed mimicking viscosity ratios found in thermal recovery processes involving hot water and heavy oil. Through these simulations, pore-scale events such as Haines jumps, oil ganglia mobilization, fingering and oil stripping in high shear flows are identified. This research discusses the capabilities and limitations of the Volume of Fluid method, and through the simulation results, important insights are provided in regards to the mechanisms of oil recovery through steam or hot water injection and on the balance of viscous and capillary forces in immiscible displacements.

description: Given the superposition of a low-rank matrix plus the product of a known fat compression matrix times a sparse matrix, the goal of this paper is to establish deterministic conditions under which exact recovery of the low-rank and sparse components becomes possible. This fundamental identifiability issue arises with traffic anomaly detection in backbone networks, and subsumes compressed sensing as well as the timely low-rank plus sparse matrix recovery tasks encountered in matrix decomposition problems. Leveraging the ability of $\ell_1$- and nuclear norms to recover sparse and low-rank matrices, a convex program is formulated to estimate the unknowns. Analysis and simulations confirm that the said convex program can recover the unknowns for sufficiently low-rank and sparse enough components, along with a compression matrix possessing an isometry property when restricted to operate on sparse vectors. When the low-rank, sparse, and compression matrices are drawn from certain random ensembles, it is established that exact recovery is possible with high probability. First-order algorithms are developed to solve the nonsmooth convex optimization problem with provable iteration complexity guarantees. Insightful tests with synthetic and real network data corroborate the effectiveness of the novel approach in unveiling traffic anomalies across flows and time, and its ability to outperform existing alternatives.

description: INTRODUCTION
 Complex cardiac surgeries, redo sternotomy cases, salvage and emergent surgeries, and patients who have high EUROSCORE II scores are known to have higher intraoperative and postoperative blood transfusions. Perpetual need of blood and blood components also mount cost and resources efficiency on National Blood Banks. Transfusion related immunologic reactions and contracting infectious diseases via blood transfusion is another major issue that has to be addressed, especially in cardiac surgeries. METHODOLODY
 A total of 130 patients who underwent CABG operation between July 2020 till March 2021 were included in this study. Patient data were obtained prospectively from hospital registry. Local ethics committee approval was obtained. All the data obtained was entered into a form. The European System for Cardiac Operative Risk Evaluation (EuroSCORE) scoring system was used for preoperative mortality risk assessment. RESULTS
 Packed cell transfusion was higher among patients with low level of preoperative haematocrit especially those who had haematocrit below 30 had a higher risk of blood transfusion preoperatively. Blood transfusion was also high among patients with chronic kidney disease and longer cardiopulmonary bypass time. Patients with a relatively low platelet count preoperatively also was a strong predictor of perioperative blood transfusion. CONCLUSION
 In our study, low preoperative hematocrit levels were associated with an increased risk of receiving a perioperative blood transfusion, which has many risks and side effects among patients undergoing Coronary Artery Bypass Surgery. Therefore, detecting and treating the cause of low preoperative hematocrit levels may eliminate unnecessary blood transfusions and undesirable consequences patients undergoing surgery.

description: When two isolated system are brought in contact, they relax to equilibrium via energy exchange. In another setting, when one of the systems is driven and the other is large, the first system reaches a steady-state which is not described by the Gibbs distribution. Here, we derive expressions for the size of energy fluctuations as a function of time in both settings, assuming that the process is composed of many small steps of energy exchange. In both cases the results depend only on the average energy flows in the system, independent of any other microscopic detail. In the steady-state we also derive an expression relating three key properties: the relaxation time of the system, the energy injection rate, and the size of the fluctuations.

description: Modeling a hydraulically fractured unconventional tight sand reservoir is a coupled hydro-mechanical problem associated with complex interactions between dynamical fracture deformation under a loading condition and multiphase flow inside a fracture network. First, a DPDK model with numerical MINC (multiple interacting continua) algorithms is utilized to represent the pressure transient within the tight matrix and interporosity flow from the matrix into a hybrid system consisting of a complex fracture network. The flow model is coupled with a FEM stress code to model the dynamical changing of fracture aperture associated with increasing of the effective normal stress during the pressure depletion. Second, the choice of a coupling approach is critical because of the slow nonlinear convergence due to a significant increase in unknowns associated with poroelasticity equations. In this thesis, the iterative coupling is adopted to solve the multiphase flow and stress equations using parallel computations because of its flexibility and efficiency compared to the fully coupled approach. A hydraulic fracture deformation mechanical model is developed and implemented into the PRSI framework. The fracture network closure is approximated by the Barton-Bandis hyperbolic deformation model, coupled with a modified Cubic Law based on a contact theory and validated by an API proppant test on proppant conductivity under loading stress. Finally, numerical examples on hydraulic fracture deformation will be presented. The coupled fluid flow-rock mechanics will illustrate the degradation of the fracture conductivity due to the increasing of normal stresses for a variety of proppant types.

We apply these junction conditions to a particular model of a Friedmann universe on the brane and show explicitly that the limit gives the standard Randall-Sundrum model Friedmann equation.

Flow of S-matrix poles for elementary quantum potentials

description: The poles of the quantum scattering matrix (S-matrix) in the complex momentum plane have been studied extensively. Bound states give rise to S-matrix poles, and other poles correspond to non-normalizable anti-bound, resonance and anti-resonance states. They describe important physics, but their locations can be difficult to find. In pioneering work, Nussenzveig performed the analysis for a square well/wall, and plotted the flow of the poles as the potential depth/height varied. More than fifty years later, however, little has been done in the way of direct generalization of those results. We point out that today we can find such poles easily and efficiently, using numerical techniques and widely available software. We study the poles of the scattering matrix for the simplest piece-wise flat potentials, with one and two adjacent (non-zero) pieces. For the finite well/wall the flow of the poles as a function of the depth/height recovers the results of Nussenzveig. We then analyze the flow for a potential with two independent parts that can be attractive or repulsive, the two-piece potential. These examples provide some insight into the complicated behavior of the resonance, anti-resonance and anti-bound poles.

description: I studied roosting behaviours of western small-footed bats (Myotis ciliolabrum) in Dinosaur Provincial Park, a semi-arid badland region in Alberta. Individuals roosted solely in the prevalent erosion-holes within the park. Regardless of sex or reproductive condition, M. ciliolabrum exhibited low roost fidelity but high fidelity to coulees. Individuals selected roosts which were high off the ground with an internal microclimate significantly buffered from external conditions, with depth not affecting roost buffering capacity. I also measured the effect of habitat on the echolocation calls for three Myotis species within the coulees and along tree edges. Myotis lucifugus and Myotis ciliolabrum significantly alter their calls between the two habitat types. Using local calls to construct a call library allowed me to determine that both M. ciliolabrum and M. evotis were present over winter. The higher proportion of M. evotis activity may be explained by gleaning insects during warmer periods.

description: The observation made in laboratory core floods is that chemical recovery of oil is achieved under high pressure gradients. A potential shortfall of core tests is their 1D nature: there are only limited water pathways established throughout the core during the initial waterflood. In this case, water channels can be blocked and the additional oil produced before chemical consequently breaks through. In actual reservoirs, with more water pathways present, there is a possibility that this blockage mechanism will not be significant, and production from chemical flooding may not work the way it does in the laboratory. This thesis presents a study on heavy oil production using chemicals in a 2D Hele-Shaw cell system. This system does not allow for capillary trapping of fluids so localized water channel blockage will not occur, and the cell is 2D so non-linear flow pathways can be visualized. Chemical injections (surfactant, polymer and SP systems) are run in the Hele-Shaw cell with the goal being to identify if there is still an improved recovery from chemical floods and, if so, to identify the production mechanisms.

Problematic non-trivial monodromies of non-geometric backgrounds in ten dimensions can be absorbed in a total derivative term such that a well-defined Lagrangian is obtained.

description: In deep-submicron CMOS technology, the switching speed of digital circuits has become extremely fast. At the same time, analog design has become increasingly difficult due to very low supply voltage levels. This makes it advantageous to represent signals in the time-domain as the delay between two digital pulse edges, rather than the conventional voltage domain. This work applies the idea of time-based processing to high-speed analog-to-digital converters (ADCs). The proposed time-based ADC consists of two stages. The first is the voltage-to-time converter (VTC), which uses a modified current-starved inverter architecture. The VTC accepts an analog voltage input and produces a series of pulses in which the delay of each pulse is proportional to the input at the time the pulse was created. The second stage is the time-to-digital converter (TDC). The TDC measures the delay on each VTC pulse and converts it to a digital logic value. The VTC and TDC can be physically separated with the VTC output transmitted to the TDC input over coaxial cables. An on-chip digital programming system in the TDC allows the entire ADC to be calibrated, and an automatic calibration scheme is presented. Two prototypes were fabricated, a 3-bit 2.5GS/s ADC in 90nm CMOS and a 4-bit 5GS/s ADC in 65nm CMOS. The 65nm circuit achieves an effective resolution bandwidth of 2.1GHz and consumes 34.6mW of power. The figure of merit is 1.0pJ/conversion. This is the fastest time-based ADC published to date.

description: The present study was conducted to examine the influence of personality and work meaningfulness on reactions to companies’ corporate social responsibility (CSR) initiatives. Participants were measured on personality and then shown a website of a hypothetical company that either presented CSR initiatives (treatment condition) or presented materials not related to CSR (control condition). Participants were then measured on the extent to which they found potential work at the company meaningful as well as how much they were attracted to the firm. Contrary to predictions, personality did not moderate the relationship between CSR and outcomes. However, consistent with predictions, work meaningfulness did mediate the relationship between CSR and firm attraction. Theoretical and practical implications of these findings are discussed.

description: Mining gene expression profiles has proven valuable for identifying metagenes, defined as linear combinations of individual genes, serving as surrogates of biological phenotypes. Typically, such metagenes are jointly generated as the result of an optimization process for dimensionality reduction. Here we present an unconstrained method for individually generating metagenes that can point to the core of the underlying biological mechanisms. We use an iterative process that starts from any seed gene and converges to one of several precise attractor metagenes representing biomolecular events, such as cell transdifferentiation or the presence of an amplicon. By analyzing six rich gene expression datasets from three different cancer types, we identified many such biomolecular events, some of which are present in all tested cancer types. We focus on several such events including a stage-associated mesenchymal transition and a grade-associated mitotic chromosomal instability.

description: We provide an extension of the recently constructed double field theory formulation of the low-energy limits of type II strings, in which the RR fields can depend simultaneously on the 10-dimensional space-time coordinates and linearly on the dual winding coordinates. For the special case that only the RR one-form of type IIA carries such a dependence, we obtain the massive deformation of type IIA supergravity due to Romans. For T-dual configurations we obtain a `massive' but non-covariant formulation of type IIB, in which the 10-dimensional diffeomorphism symmetry is deformed by the mass parameter.

We also show that these Leavitt path algebras have the additional (unusual) property that all their Lie ideals are (ring-theoretic) ideals, and construct examples of such rings with various ideal structures.

description: Electro-deposition is versatile method for producing metal composite coatings on surfaces for protection against wear and corrosion. The electro-deposition of nano-sized ceramic composite coatings is novel and offers coatings with superior properties compared to conventional pure metallic coatings. The co-deposition process can provide a cost effective solution to coat complex geometries and internal surfaces of components or hard to reach surfaces with high degree of control on coat thickness and characteristics. In this research nickel composite coatings was co-electrodeposited with 3 different types of ceramic oxide particles (Y2O3, TiO2, or Al2O3). The effect of electroplating parameters on the distribution of these nano-sized particles and the impact of this distribution on mechanical and physical properties were examined. It was found that the type of ceramic dispersoids used directly affected the coat hardness, with the highest value produced with Al2O3 dispersion (600VHN), followed by Y2O3 (550VHN) and then TiO2 (500VHN). Furthermore, the type of ceramic used and the values of different plating parameters changed the deposition rates, the cohesive strength of the coating and the extent of agglomeration of these nano particles within the coating. A mechanism was proposed to describe the agglomeration phenomena and the key factors that affect it, aiming at finding the optimum ranges that controls the extent of particles agglomeration within the coatings, and then the experimental observations were used to validate this mechanism.

description: An extensive b-value power law analysis is carried out on a large dataset of microseismic events accumulated from over 300 stages during the hydraulic fracture treatment of three wellpads in the Horn River basin. This analysis is carried out on three different length scales: the single stage level, the level of the formation and finally in a 3D volume. A comparison of three commonly used statistical methods of analysis is carried out at the stage level to determine the statistical validity of these methods. B-value analysis is a form of statistical analysis which is highly sensitive to the statistical methods being employed as well as the size of the data sample. B-values themselves are not a completely self-sufficient and quantitative description of the stress state of the medium but must be combined with other observations involving other geoscience methods such as seismic and well-log analysis along with engineering data.

description: We discuss the interplay between lagrangian distributions and connections in symplectic geometry, beginning with the traditional case of symplectic manifolds and then passing to the more general context of poly- and multisymplectic structures on fiber bundles, which is relevant for the covariant hamiltonian formulation of classical field theory. In particular, we generalize Weinstein's tubular neighborhood theorem for symplectic manifolds carrying a (simple) lagrangian foliation to this situation. In all cases, the Bott connection, or an appropriately extended version thereof, plays a central role.

description: To enable investigation of spatial orientation abilities across a range of ages and developmental abilities, we developed a navigation task comprised of a video game in a virtual museum in which subjects were required to find different rooms with distinct themes. We then validated the task by studying a large number of healthy young adults and confirming a strong correlation with self-reported orientation abilities in everyday life (Chapter 2). We also analysed performance on the navigation task as it related to demographics and video game use, verifying previously observed gender differences and demonstrating that individuals with a longer history of video game play, as well as participants who played video games that required navigation, performed better than individuals without experience navigating in video games. Our evidence, therefore, supports the hypothesis that better navigation and orientation skills in individuals playing video games are likely due to the consistent practice of those skills while playing for entertainment (Chapter 2). Children who have experienced a stroke around the time of birth have been shown to have IQ in the normal or near normal range as a group; however a portion of children has consistently demonstrated cognitive delays. Utilizing both concurrent neuropsychological testing and pre-existing clinical data, we found that the factors that were predictive of initial performance on the spatial orientation task were age, gender, motor dexterity, the presence of Arterial Ischemic Stroke (AIS), and loss of grey matter volume (Chapter 3). Furthermore, the modest deficits in topographical orientation, seen in AIS patients, were ameliorated by further practice and were no longer seen after the second time playing the video game. In contrast, AIS, parental education and involvement of the dorsolateral prefrontal (DLPF) cortex were predictive factors for full-scale intelligence quotient (FSIQ). Loss of tissue volume predicted reduced verbal comprehension index (VCI) scores (Chapter 3). The relative preservation of spatial orientation, a multifaceted behaviour with a prolonged developmental course, would lend support to the hypothesis that injury within a network allows for better resiliency of that skill and may be an illustration that there is better recovery of an ability if injury occurs before that proficiency has fully matured.
SBV Regularity for Genuinely Nonlinear, Strictly Hyperbolic Systems of Conservation Laws in one space dimension

description: We prove that if $t \mapsto u(t) \in \mathrm {BV}(\R)$ is the entropy solution to a $N \times N$ strictly hyperbolic system of conservation laws with genuinely nonlinear characteristic fields \[ u_t + f(u)_x = 0, \] then up to a countable set of times $\{t_n\}_{n \in \mathbb N}$ the function $u(t)$ is in $\mathrm {SBV}$, i.e. its distributional derivative $u_x$ is a measure with no Cantorian part. The proof is based on the decomposition of $u_x(t)$ into waves belonging to the characteristic families \[ u(t) = \sum_{i=1}^N v_i(t) \tilde r_i(t), \quad v_i(t) \in \mathcal M(\R), \ \tilde r_i(t) \in \mathrm R^N, \] and the balance of the continuous/jump part of the measures $v_i$ in regions bounded by characteristics. To this aim, a new interaction measure $μ_{i,\jump}$ is introduced, controlling the creation of atoms in the measure $v_i(t)$. The main argument of the proof is that for all $t$ where the Cantorian part of $v_i$ is not 0, either the Glimm functional has a downward jump, or there is a cancellation of waves or the measure $μ_{i,\mathrm{jump}}$ is positive.

description: We formulate macroscopic quantum electrodynamics for the most general linear, absorbing media. In particular, Onsager reciprocity is not assumed to hold. For media with a non-local response, the field quantisation is based on the conductivity tensor and the Green tensor for the electromagnetic field. For a local medium response, we introduce the permittivity, permeability and magnetoelectric susceptibilities to obtain an explicitly duality-invariant scheme. We find that duality invariance only holds as a continuous symmetry when non-reciprocal responses are allowed for.

description: This research explored what people with a history of childhood physical/sexual abuse perceived to have helped or hindered the formation of a therapeutic alliance in counselling. Using the methodology of the enhanced critical incident technique, 10 participants were interviewed about what helped or hindered their building a strong working alliance, as well as what factors they wish had been present. From these interviews, 17 categories were generated. The seven helping categories were: (a) Counsellor’s skills or approach was effective, (b) Facilitated communication, (c) Counsellor was personable, (d) Counsellor was a woman, (e) Personal characteristics of the counsellor, (f) Trust/Non-judgement and (g) Accessibility. The seven hindering categories were (a) Not offering solutions or follow-up, (b) Unsuitable or incompatible interpersonal style, (c) Therapeutic approach or skills were not a fit, (d) Did not facilitate communication, (e) Lack of understanding, (f) Disrespect, and (g) Having to change counsellors. The three wish list item categories were (a) Facilitate communication more, (b) Incorporate wellness factors, and (c) More accessible. These categories are discussed in relation to the literature on both the working alliance and childhood abuse. Recommendations for counselling professionals are offered based on the findings and the scholarly literature.
