description: We present the analysis of the bright X-ray binary 4U 1820-30, based mainly on XMM-Newton-RGS data, but using complementary data from XMM-Epic, Integral, and Chandra-HETG, to investigate different aspects of the source. The broad band continuum is well fitted by a classical combination of black body and Comptonized emission. The continuum shape and the high flux of the source (L/L_Edd\sim0.16) are consistent with a "high state" of the source. We do not find significant evidence of iron emission at energies >=6.4 keV. The soft X-ray spectrum contain a number of absorption features. Here we focus on the cold-mildly ionized gas. The neutral gas column density is N_H\sim1.63x10^21 cm^-2. The detailed study of the oxygen and iron edge reveals that those elements are depleted, defined here as the ratio between dust and the total ISM cold phase, by a factor 0.20\pm0.02 and 0.87\pm0.14, respectively. Using the available dust models, the best fit points to a major contribution of Mg-rich silicates, with metallic iron inclusion. Although we find that a large fraction of Fe is in dust form, the fit shows that Fe-rich silicates are disfavored. The measured Mg:Fe ratio is 2.0\pm0.3. Interestingly, this modeling may point to a well studied dust constituent (GEMS), sometimes proposed as a silicate constituent in our Galaxy. Oxygen and iron are found to be slightly over- and under-abundant, respectively (1.23 and 0.85 times the solar value) along this line of sight. We also report the detection of two absorption lines, tentatively identified as part of an outflow of mildly ionized gas (ξ\sim-0.5) at a velocity of \sim1200 km/s.

Candidate gene association studies of chronic obstructive pulmonary disease and asthma
Creators: name: He, Jianqing
Publisher: name: University of British Columbia

description: COPD and asthma are complex diseases characterized by pulmonary inflammation. The roles of single nucleotide polymorphisms (SNPs) in the inflammatory cytokine IL10, IL10RA, CSF2, CSF3 and IL6 in COPD and SNPs in a Th2-polarizing cytokine thymic stromal lymphopoietin (TSLP) in asthma are not clear. Association studies were performed to explore the genetic contribution of these cytokines to COPD or asthma. Housekeeping genes on airway epithelium were also optimized. In the study of COPD in the Lung Health Study (LHS), no association was found for IL10, IL10RA and CSF2; an increase in the number of CSF3 -1719T alleles was associated with protection against low forced expiratory volume in one second (FEV₁), odds ratio (OR) = .73, 95% confidence interval (CI) = .56 - .95, P = .018; three IL6 SNPs were associated with the rate of decline of FEV₁ (.023 ≤ P ≤ .041 in additive models). In the National Emphysema Treatment Trial - Normative Aging Study, IL6_-174G/C and four other highly linked SNPs were associated with COPD (.01 ≤ P ≤ .04 in additive genetic models). Association between IL6 and rate of FEV₁ decline was the most statistically significant observations in all of our studies in LHS, which has examined more than 40 candidate genes. In the study of TSLP association with asthma, the A allele of rs1837253 was associated with protection from asthma, atopic asthma, and airway hyperresponsiveness (AHR), with ORs (95% CI) and corrected P values for each being .79 (.69 - .90) and .0058; .75 (.63 - .88) and .0074; and .76 (.64 – .89) and .0094, respectively. These associations were the most statistically significant observations in our study, which has examined 98 candidate genes. Cyclophilin A was identified as the most suitable normalizer in gene expression studies involving human airway epithelium. In summary, we demonstrate for the first time that IL6 SNPs are associated with rapid decline of FEV₁ and COPD; TSLP SNPs are associated with asthma and AHR. These results will help our understanding of COPD and asthma and lead to more effective and individualized strategies for the management of COPD and asthma.

description: We show that the charge asymmetry in t tbar production at the LHC, A_C, and the forward-backward asymmetry at the Tevatron, A_FB, are in general not tightly correlated. They can even have opposite signs, if the underlying new physics (NP) model is general enough. We demonstrate this using two examples of NP: a light axigluon, and a vector that is a color octet and electroweak triplet. The small value of A_C measured at the LHC is thus shown not to exclude a NP interpretation of the anomalously large A_FB at the Tevatron. We identify two observables where significant NP effects are still expected at the Tevatron and the LHC, the b bbar production forward-backward asymmetry and spin polarizations of the pair-produced tops and anti-tops.

description: A discussion on the intricacies of enterprise search; contrasting web search, the systems distributed nature, various applications, and evaluation measures. Following this, a shift in focus to expertise search and the development of the Terrorist Expertise Locator (TEL), built using the latest open source enterprise search technology. Implementation follows an enterprise search methodology centered on tuning relevancy for the applicable dataset, in this case the Global Terrorism Database (GTD). Data analysis drives the application of information retrieval and information extraction techniques; stemming, query expansion, query operators, and document quality weighting. Evaluation of the enterprise search engine, in various configurations, provide insight into best practices used to improve relevancy. Three expertise calculation methods are compared; count-based, relevancy weighted, and expertise weighted. Validation of results are established by cross-referencing un-indexed popular media and government sources, including CBC news reports and FBI declassified files.

description: We outline the many quarkonium-physics opportunities offered by a multi-purpose fixed-target experiment using the p and Pb LHC beams extracted by a bent crystal. This provides an integrated luminosity of 0.5 fb-1 per year on a typical 1cm-long target. Such an extraction mode does not alter the performance of the collider experiments at the LHC. With such a high luminosity, one can analyse quarkonium production in great details in pp, pd and pA collisions at sqrt(sNN)~115 GeV and at sqrt(sNN)~72 GeV in PbA collisions. In a typical pp (pA) run, the obtained quarkonium yields per unit of rapidity are 2-3 orders of magnitude larger than those expected at RHIC and about respectively 10 (70) times larger than for ALICE. In PbA, they are comparable. By instrumenting the target-rapidity region, the large negative-xF domain can be accessed for the first time, greatly extending previous measurements by Hera-B and E866. Such analyses should help resolving the quarkonium-production controversies and clear the way for gluon PDF extraction via quarkonium studies. The nuclear target-species versatility provides a unique opportunity to study nuclear matter and the features of the hot and dense matter formed in PbA collisions. A polarised proton target allows the study of transverse-spin asymmetries in J/psi and Upsilon production, providing access to the gluon and charm Sivers functions.

Pixarticulation : the voice in contemporary animated cinema
Creators: name: Montgomery, Colleen
Publisher: name: University of British Columbia
Year: 2010

description: Since releasing the first animated feature film Toy Story in 1995, Pixar has radically altered contemporary animated filmmaking/viewing practices. Yet, inasmuch as Pixar’s popularization of digital rendering technologies has had a profound impact on the visual aesthetics of animation, the studio’s use of the voice—on both a narrative and extratextual level—is also at the forefront of a profound aesthetic and economic reshaping of the aural, and more precisely, vocal landscape of contemporary animated cinema. Whereas Pixar’s parent corporation, The Walt Disney Company, is a critical focal point in animation studies, as Chapter One outlines, Pixar has remained largely absent from scholarly discourses on animation. As a corrective to this critical lacuna, Chapter Two proposes a triangulation of animation/Disney criticism, psychoanalysis, and media theory, for thinking Pixar’s use of the voice. Chapter Three contextualizes this analysis, providing a critical overview of American animation history, emphasizing Mike Budd, Max Kirsch, and Janet Wasko’s writing on Disney’s corporate and artistic practices. Moving towards a theory of Pixar animation’s relationship to the voice, Chapter Four outlines the studio’s history and relevance to contemporary animation. Drawing from Michel Chion and Mladen Dolar’s psychoanalytic theories of the voice (and cinema), Chapters Five and Six present two case studies that elucidate the textual dimensions of Pixar’s voices. The first of these centres on Toy Story and Toy Story 2, both of which feature a complex mix of mechanical, acousmatic and ventriloquial voices, while the second case study focuses on Monsters, Inc. and its interrogation of the symbolic, linguistic and cultural functions of the scream and laughter. Finally, Chapter Seven examines the extratextual use of the voice as a part of Pixar’s promotional discourses, intensive, synergistic branding strategies, and cultivation of a broad audience demographic. This chapter calls upon Barbara Klinger and Martin Barker’s respective discussions of the role that promotional materials play in influencing a text’s reception, and Noël Carroll’s writing on intertextuality, proposing that the use of the voice in Pixar’s marketing campaigns structures an intertextual, multi-tiered mode of reception for reading its films—a process which I here term ‘Pixarticulation.’

description: This study explores the source of inconsistent and unemotional performances by voice students in higher education music programs. The emphasis will be on how to address this through vocal instruction. Many varying approaches to vocal instruction exist in higher education programs which appear to prolong inconsistency and unengaged performing. The research explores several existentialist principles of Jean-Paul Sartre and how these principles may inform and enhance current vocal teaching practice in higher education and perhaps better prepare new voice teachers. The following study will consider the effectiveness of the application of Sartre’s existentialist principles and how they may inform vocal instruction and improve vocal development.

This process is claimed to be correlated to the emergence of the power-law distribution of the discussion lengths observed in the dialogues. We perform numerical simulations based on the noticed phenomenon obtaining a good agreement with the real data. Finally, we propose a method to artificially prolong the duration of the discussion that relies on the entropy of emotional probability distribution.

description: This study explores the interplay of adult educator backgrounds with organizational contexts and discusses how those elements combine to inform teacher practice. Using life history methodology as a basis for educational research, this study connected life experience to educational practice by examining the relationship of individual adult educator histories and the workplace settings in which their educator practices were situated. The primary purpose of this study was to explore aspects of life journeys that relate to the practice of adult education and correlate this understanding to examine how specific workplace contexts influence courses of action and decision-making in adult teaching and learning environments. A significant part of this research included an inquiry into how educators convey a personal essence within their instruction in order to form holistic or authentic teacher practices based on the tenets of transformative and critical adult education. Elements emerging from the data in this research pointed to how the unique position of adult educators, particularly in the area of English language teaching (ELT), enables educational practitioners to bridge gaps between educational practice, business agendas, and organizational paradigms. At the same time, in understanding links from personal to professional aspects of self, data from this research highlighted the notion of ELT as providing rather unstable workplace contexts that influence and possibly restrict educator ability to develop self-identity and authenticity.

description: The feasibility of underground injection and storage of CO2 is associated with many technical and economic challenges. Careful engineering design, economic evaluation, and risk assessment are essential steps towards successful implementation of such complex projects. To address some of these issues, reservoir simulations were conducted on different prototypes with properties relevant to potential storage sites in Alberta. The study covers important aspects of injection into two major types of geological formations: saline aquifers and hydrocarbon reservoirs. In the case of CO2 storage into saline aquifers, the two important studied phenomena were (i) the fate of dissolved H2S in a sour aquifer and (ii) the feasibility of injecting large volumes of CO2 into a very large aquifer. In the case of CO2 storage in hydrocarbon reservoirs, the feasibility of CO2 EOR/ storage in the tight portion of Pembina Cardium field was studied. Various design parameters and operating conditions can affect the performance of a WAG flood. The parameters considered here are those related to development pattern, hydraulic fracture geometry, WAG parameters and the timing of the switch between different schemes. CO2 EOR performance was assessed based on the oil recovery factor and the amount of stored CO2. However, to reflect the effect of time, the net present value of the projects was also considered. The effect of all parameters on objective functions was investigated using a compositional simulator. Design of experiment was then utilized to perform a comprehensive statistical analysis to recognize the most prominent factors in fulfillment of each objective function. Response surfaces were generated to quantify the effect of the factors on the objective functions. Optimization was carried out to find those sets of factors, which provided the highest recovery, storage, and NPV. To reduce the uncertainty related to CO2-EOR projects, comprehensive economic studies are required to minimize the risk of failure under different market. Therefore, a rigorous workflow was provided for the industry to evaluate CO2 EOR and storage in tight oil reservoirs. Based on this workflow, it would be possible to quantify the amount of incentives required to make the coupled CO2 EOR and storage economically attractive.

description: In this study, new approaches were adopted toward the template-free synthesis and modification of LTY, LTL and ZSM-5 zeolites via the direct hydrothermal synthesis method, without using any organic structure directing agent or seeding gel. The original and modified zeolites were characterized by x-ray diffraction, Fourier-transformed infrared spectroscopy, solid state nuclear magnetic resonance spectroscopy, scanning electron microscopy, Brunauer–Emmett–Teller surface area analysis, and energy dispersive x-ray spectroscopy. Moreover, the prepared zeolites were applied as catalysts in pyrolysis experiments in a bench scale horizontal reactor with Saskatchewan boundary dam coal, and their influences on the solid, liquid and gaseous products of this reaction were investigated using gas chromatography (GC), gas chromatography–mass spectrometry (GCMS) and CHNS/O elemental analysis. Furthermore, the influence of the catalysts on the pyrolysis kinetics was studied using thermogravimetric analysis.
Comparison of leg muscle activity and vibration propagation during whole body vibration between older and young adult populations

description: Whole body vibration (WBV) platforms are commonly used as a tool to enhance muscle activity. Scientific literature has studied these platforms to understand how certain boundary conditions (vibration frequency, amplitude, standing position, etc.) affect muscle activity. These studies focused primarily on young, trained adults. Older adults may also benefit from these platforms, but may react differently to a vibration stimulus. Another aspect studied relates to the acceleration experienced throughout the body during WBV, as high accelerations may produce undesirable effects. However, the effect of age on these results has not been quantified. Therefore, the purpose of this study was to compare leg muscle activity and the transmission of acceleration through the body in older adults (55+ years) and younger, trained adults (18 to 35 years). The effect of different vibration frequencies (6Hz, 11Hz, and 16Hz) and different amplitudes (0.9mm, 2.5mm, and 4mm) were quantified and compared. When compared to younger adults, older adults experienced higher muscle activity in six of seven muscles measured. Altering the vibration amplitude affected the muscle activity more than altering the vibration frequency. The acceleration transmission was similar for the young and the old cohorts.
Proneural Genes in Neocortical Development

description: The timing of neocortical development is regulated by both intrinsic proneural genes Neurog2 and Ascl1, and extrinsic signals. However, how these intrinsic factors and extrinsic signals coordinatedly control neural cell fate decisions was not well understood at the start of my studies. Neurog2 and Ascl1 were known to be expressed by dorsal and ventral telencephalic progenitors, respectively. In the embryonic dorsal telencephalon, Neurog2 was known to promote the differentiation of glutamatergic projection neurons, while in the ventral telencephalon, Ascl1 was known to promote the formation of GABAergic interneurons and oligodendrocyte precursor cells (OPCs). However, little was understood about the regulatory controls that governed Neurog2 and Asc11’s proneural activities. During my PhD study, I first found that the proneural activity of Neurog2 declined at later stages of cortical neurogenesis, which was controlled by a simultaneous increase in GSK3 activity (Chapter 3). Furthermore I found that GSK3 inhibited Neurog2’s proneural activity through direct phosphorylation, which altered Neurog2-cofactor interactions. Next, I found that RAS/ERK signaling controlled a Neurog2-Ascl1 genetic switch, promoting Ascl1 expression while inhibiting Neurog2 expression (Chapter 4). Moreover, I found that RAS/ERK signaling modified Ascl1’s functions through direct phosphorylation, with higher levels of RAS/ERK causing Ascl1 to select OPC differentiation pathways, while lower levels allowed Ascl1 to promote a GABAergic neuronal fate. Notably, the interaction between RAS/ERK signaling and Ascl1 was found to be important in both normal neocortical development and in gliomagenesis. Finally, I observed that Neurog2 and Ascl1 proteins were co-expressed in a subset of early cortical progenitors, with the frequency of co-expression declining over developmental time (Chapter 5). Furthermore, I found that the Neurog2-Ascl1 co-expression is associated with enhanced neural stem cell properties and a decreased propensity to undergo neuronal differentiation. Accordingly, in Neurog2-/-;Ascl1-/- double mutant cortices, I found that neurogenesis and laminar marker expression was accelerated. I thus conclude that the Neurog2-Ascl1 co-expression ‘primes’ a subset of cortical progenitors to prevent lineage selection until later in development. Taken together, I made a great deal of progress in improving our understanding of how the proneural genes cooperate with extrinsic signals to regulate the timing of neocortical development.
The Role of Abscisic Acid in Arabidopsis thaliana Shoot Organogenesis

description: One of the most fundamental studies of plant biology is to understand the formation of shoot (SAM) and root (RAM) apical meristems and how they maintain post-embryonic development of the plant body. My thesis entitled ‘The role of abscisic acid in Arabidopsis thaliana shoot organogenesis’ seeks to understand shoot apical meristem initiation from zygotic embryo explants during in vitro culture conditions. An efficient shoot regeneration protocol based on abscisic acid (ABA), a key additive in the shoot induction medium, assures greater number of normal shoots, and serves as an excellent experimental system to carry out the proposed research. None of the available Arabidopsis protocols mention the importance of ABA on shoot regeneration. Both fluridone treatment and regeneration studies using an aba3-2 mutant demonstrated that a reduced level of ABA greatly inhibited shoot regeneration. Histological studies indicated the organogenic calluses were produced from procambium cell files and the SAM was differentiated from meristemoid cell clusters near the surface of the organogenic callus. Supplementation of ABA along with cytokinin enhanced WUSCHEL (WUS) expression, a stem cell specifying homeodomain transcription factor, and it was localized close to vascular tissues of organogenic calluses. The results were confirmed by quantitative PCR, RNA in situ hybridization, and a WUS reporter line. The precise spatial and temporal expressions of WUS most likely resulted in SAM cell specification. Drastic reduction of shoot regeneration from a wus-1 mutant suggests that WUS is a main downstream player of ABA treatment. In addition to WUS, elevated expression of ABA responsive transcription factor ABSCISIC INSENSITIVE 5 at the earlier stages of shoot induction and the broader expression ABSCISIC INSENSITIVE 3 in the organogenic calluses suggest the possible role of these factors on shoot organogenesis. The findings from this thesis indicate a strong positive role of ABA on cellular and developmental events of Arabidopsis SAM specification and initiation. Our findings have potential applications on the improvement of propagation systems of recalcitrant species through the manipulation of culture conditions, specifically through the supplementation of ABA.

description: Despite decades of research, homelessness remains a paradoxical feature of even the most affluent societies, including Canada. Since the early 1980s, there has been a renewed academic and policy interest in homelessness. Existing research is predominantly quantitative in nature and focuses on the identification of individual-level factors contributing to homelessness. A growing body of research focuses on the ways in which institutional environments produce “the homeless” as knowable subjects and shape their day-to-day experiences. My dissertation explores ethnographically the social organization of service provision to homeless families at the Guest House, a Calgary family shelter. I conducted in-depth interviews with shelter guests and staff, engaged in participant observation, and analyzed various documents, such as institutional records, policy documents, and news reports. My discussion begins with an account of individual experiences of becoming homeless and shelter life, which is based on nine in-depth interviews with shelter guests. My attention then shifts to the social practices that shaped these experiences. To understand the context in which services to homeless families are provided at the Guest House, I examine the processes that shaped the institutional foundation of the Guest House. My discussion continues with an examination of the complex, socially organized processes, such as policy mandates, funding stipulation and structures of accountability, that shape day-to-day practices of shelter staff and administrators. This discussion is based on data I generated through extensive participation in those shelter practices as a volunteer and frontline staff member. Using the example of shelter-admission decisions, I show how homeless families are transformed into shelter residents. While staff members have the discretion to admit or reject shelter-seeking families, their decisions are shaped by realities that are beyond the control of individual actors, such as economic conditions, the real estate market organizational stipulations, funding provisions, and political mandates imposed by Calgary’s Ten Year Plan to End Homelessness. My discussion demonstrates that institutional practices do not originate exclusively within the institution itself, but are organized by principles located outside the organization. In other words, shelter staff might be the captain of their ship, but they are not the master of the sea.

description: These slides are part of the 2nd Mapping Commons Workshop on Simple Standard for Sharing Ontological Mappings Conference: 16th Annual International Biocuration Conference in Padlova, Italy Workshop Description Website: https://biocuration2023.github.io/workshops Despite significant advances in standardisation and FAIRification of data, global interoperability remains an elusive goal. The decentralised nature of standardisation causes semantic spaces to emerge which are governed by diverse standards, in particular controlled vocabularies and semantic data models. To facilitate interoperability across standards, we need to curate and publish mappings. The Simple Standard for Sharing Ontological Mappings (SSSOM) has been proposed as a standard model for sharing FAIR semantic entity mappings. While the core of the standard model has been solidified, certain issues remain; in particular, the representation of complex mappings (mappings that involve more than 2 entities) and entity-literal mappings. Furthermore, certain use cases remain only partially supported, such as value set mappings and schema crosswalks. In this workshop, we aim to: Develop a common understanding of the problem of non-simple mappings Determine if SSSOM is suitable to cover some or all of these non-simple mapping problems Potentially gather requirements on how SSSOM needs to be extended to cover more of them This workshop is organised by members of the Monarch Initiative, the SSSOM developer community, FAIR Impact, and FAIRCORE4EOSC.

description: Thermal methods are extensively used to extract heavy oil and bitumen with reasonable recovery percentages to compensate for the light oil production decline in recent years. In addition, new technologies are tested to increase the value of the produced liquids. Nanoparticles technology is emerging as a new alternate technology for enhancing the upgrading and recovery processes of heavy oil. Ultra-dispersed nanocatalysts can be injected into the reservoir along with hydrogen to enhance both the upgrading and recovery of heavy oil. Nanocatalysts can be introduced into the reservoir at a typical SAGD configuration (in the area between injector and producer) with the desired residence time to produce higher quality products with enhanced heavy oil recovery. However, before applying these nanocatalysts in the field and testing their performance, their transport behavior inside the porous media and catalytic activity towards heavy oil upgrading and subsequently recovery enhancement has to be determined. In this study, a pilot plant unit was built in-house to investigate the performance of multi-metallic nanoparticles in an oil sand packed bed column at high pressure and temperature conditions. Results showed that nanoparticles could be controllably delivered inside the medium with a meager influence on the medium permeability. In addition, deposition of the nanoparticles mainly occurs at the entrance of injection zone and rapidly decreases across the reaction zone. Moreover, effect of different hot fluid injection scenarios on recovery enhancement has been evaluated in presence and absence of tri-metallic nanocatalysts. Comparing the iii recovery curves show effectiveness of nanocatalysts on recovery enhancement. In addition, presence of nanocatalysts inside the porous media along with hydrogen enhanced the quality of produced liquids by reducing the hydrocarbon residue and micro carbon content. Furthermore, significant enhancement of liquid viscosity and API gravity was achieved. In the other side, using the nanocatalysts enhanced the hydrocracking reactions by reducing coke formation as well as reduction of carbon dioxide emission, which reduces the environmental impact of nanocatalysts on the in-situ upgrading processes.

description: Probability distributions of human displacements has been fit with exponentially truncated Lévy flights or fat tailed Pareto inverse power law probability distributions. Thus, people usually stay within a given location (for example, the city of residence), but with a non-vanishing frequency they visit nearby or far locations too. Herein, we show that an important empirical distribution of human displacements (range: from 1 to 1000 km) can be well fit by three consecutive Pareto distributions with simple integer exponents equal to 1, 2 and ($\gtrapprox$) 3. These three exponents correspond to three displacement range zones of about 1 km $\lesssim Δr \lesssim$ 10 km, 10 km $\lesssim Δr \lesssim$ 300 km and 300 km $\lesssim Δr \lesssim $ 1000 km, respectively. These three zones can be geographically and physically well determined as displacements within a city, visits to nearby cities that may occur within just one-day trips, and visit to far locations that may require multi-days trips. The incremental integer values of the three exponents can be easily explained with a three-scale mobility cost/benefit model for human displacements based on simple geometrical constrains. Essentially, people would divide the space into three major regions (close, medium and far distances) and would assume that the travel benefits are randomly/uniformly distributed mostly only within specific urban-like areas.

description: This Master’s thesis investigates collection management from a life cycle sustainability perspective. The final aim of this research is to support the integration of disposal within collection management decision-making through the design of an evaluative framework and supportive tool. Deselection is recognized as an important management tool for collection sustainability. Due to impacts inherent to any disposal activity, collection disposal falls under professional responsibilities of responsible resource management. How deselected material is then handled is an important component of the sustainable library. A history of libraries and collection management, from acquisition to disposal, is examined. This is supported by a qualitative analysis of current collection disposal experiences in Alberta and a quantitative analysis of collection deselection in Canada. A life cycle assessment method is proposed and disposal impacts are identified and assessed. Viewing collections from a life cycle perspective, including disposal, provides additional insight to further promote sustainable collection management.
Jacobi-SVD Channel Estimation for Amplify and Forward MIMO Relay

Subjects: Engineering--Electronics and Electrical

description: In this thesis we present a least squares based channel estimation scheme for amplify and forward relaying systems. Firstly, a composite channel estimate is obtained at the destination by least squares method. This is followed by a sequence of least squares minimizations and Jacobi rotation to obtain individual channel estimates of source-relay and relay-destination channels. Theoretical method of obtaining singular value decomposition by computing the Eigen decomposition of gram matrix have proven to be very difficult and impractical to implement due to associated numerical difficulties. Therefore Jacobi Singular Value Decomposition parallel algorithm for channel decomposition is proposed. Performance evaluation is carried out to determine the accuracy of individual channel estimates using normalized mean square error (NMSE). It was also shown that using the channel state information (CSI) of source-relay channel to determine the relay gain improves the BER performance of the system.

Enhanced addressability and localization in digital microfluidic multiplexer systems

Publisher: name: University of British Columbia

description: This research presents a novel digital microfluidic multiplexer structure based on a cross-referencing architecture. The new multiplexing technique uses bi-polar voltage activation and threshold effects to overcome addressability limitations and eliminate inter-microdroplet interference. Fan et al. in 2002 introduced cross-referencing for enhancing addressability. The technique uses two sets of rectangular electrodes: top rows and bottom columns. Such a system achieves m+n addressability with only m+n electrodes. This is a significant achievement as voltage addressing and microdroplet actuation are performed by the same linear electrode structures. There remains one major drawback to the conventional cross-referencing method. Desired motion of a microdroplet on an electrode grid can result in undesired motion of other microdroplets placed on the same electrode row. Other groups have proposed intriguing solutions to this problem with cascaded differential voltage activation and graph theory, respectively. However, these methods become increasingly complex for systems with multiple microdroplets, as the solutions for addressability must have a limited number of microdroplets. The proposed method introduces a new multiplexing format for cross-referencing of DMF systems through the simultaneous use of threshold-based voltage actuation (which sets a minimum voltage to initiate microdroplet motion) and bi-polar voltage activation on the overlying and underlying electrodes. The threshold voltage effect for requirement one has been characterized numerically and experimentally, and the results are presented here. With regard to requirement two, it is necessary to employ a voltage addressing scheme that can preferentially isolate overlapped regions of the 2-D grid. This goal can be achieved using a bi-polar electrode activation technique, as the bi-polar DMF multiplexers will have a ±2Vapp voltage difference in the overlapped location and only a maximum of ±1 Vapp voltage difference in all other locations. This relationship has been quantified using an electrostatic 3-D COMSOL model of the proposed DMF multiplexer. A fabrication recipe for the proposed DMF multiplexer system is reported in this research, and the multiplexing protocol has been studied experimentally to verify the numerical analyses. The proposed technique with this threshold-based bi-polar activation can improve mxn addressability with multiple microdroplets in a cross-referenced DMF grid.
