description: We describe the clinical course of a recurrent case of congenital fibrosarcoma diagnosed in a 9-mo-old boy with a history of hemimelia. Following complete surgical resection of the primary tumor, the patient subsequently presented with bulky bilateral pulmonary metastases 6 mo following surgery. Molecular characterization of the tumor revealed the absence of the prototypical ETV6-NTRK3 translocation. However, tumor characterization incorporating cytogenetic, array comparative genomic hybridization, and RNA sequencing analyses, revealed a somatic t(2;15)(2p21;15q25) translocation resulting in the novel fusion of EML4 with NTRK3. Cloning and expression of EML4-NTRK3 in murine fibroblast NIH 3T3 cells revealed a potent tumorigenic phenotype as assessed in vitro and in vivo. These results demonstrate that multiple fusion partners targeting NTRK3 can contribute to the development of congenital fibrosarcoma.
Neonatal pain and COMT Val158Met genotype in relation to serotonin transporter (SLC6A4) promoter methylation in very preterm children at school age
Creators: name: Chau, Cecil Ming Yeung
Publisher: name: University of British Columbia
Year: 2015

description: Children born very preterm are exposed to repeated neonatal procedures that induce pain and stress during hospitalization in the neonatal intensive care unit (NICU). The COMT Val158Met genotype is involved with pain sensitivity, and early life stress is implicated in altered expression of methylation of the serotonin transporter. We examined: (1) whether methylation of the serotonin transporter gene (SLC6A4) promoter differs between very preterm children and full-term controls at school age, (2) relationships with child behavior problems, and (3) whether the extent of neonatal pain exposure interacts with the COMT Val158Met genotype to predict SLC6A4 methylation at 7 years in the very preterm children. We examined the associations between the COMT genotypes, neonatal pain exposure (adjusted for neonatal clinical confounders), SLC6A4 methylation and behavior problems. Very preterm children had significantly higher methylation at 7/10 CpG sites in the SLC6A4 promoter compared to full-term controls at 7 years. Neonatal pain (adjusted for clinical confounders) was significantly associated with total child behaviour problems on the Child Behavior Checklist (CBCL) questionnaire (adjusted for concurrent stressors and 5HTTLPR genotype, p = 0.035). CBCL Total Problems was significantly associated with greater SLC6A4 methylation in very preterm children (p = 0.01). Neonatal pain (adjusted for clinical confounders) and COMT Met/Met genotype were associated with SLC6A4 promoter methylation in very preterm children (p = 0.001). These findings provide evidence that both genetic predisposition and early environment need to be considered in understanding susceptibility for developing behavioral problems in this vulnerable population.
The interplay of emotional awareness and emotion regulation strategies in peer victimization
Creators: name: Low, Sok Yee
Publisher: name: University of British Columbia
Year: 2015

description: Peer victimization is an emotionally charged experience, one that is all too common in schools today. Although there is an increasing body of research on the emotional processes involved in bullying and victimization, we still know very little about emotional competencies and emotion regulation strategies used by children that enhance or reduce their risk of being victimized at school. This study examined two interrelated components of emotional competence: emotional awareness and the use of two well-researched emotion regulation strategies- cognitive reappraisal and expressive suppression, and their association with school victimization. In particular, the study investigated the contribution of children’s levels of emotional awareness to their risk of victimization, and how using an antecedent-focused strategy such as reappraisal, or a response-focused strategy such as suppression influences this relationship. Participants were 607 students in grades 4-7 who completed self-report measures of emotional awareness, emotion regulation strategy use (cognitive reappraisal and expressive suppression), and experiences of victimization at school. Ordinary least squares regression analyses were conducted to explore the associations between low emotional awareness and the use of specific emotion regulation strategies. Results indicated that low emotional awareness was a predictor for the use of suppression as an emotion regulation strategy. Results of binary logistic regression analysis, examining the contributions of low emotional awareness and the use of suppression and reappraisal to reported victimization showed that low emotional awareness was associated with increased odds of being victimized, and that the use of suppression as an emotion regulation strategy decreased the odds of being victimized. For this age group, then, using suppression as an emotion regulation strategy is adaptive for decreasing the risk of victimization, particularly for children with low emotional awareness.

description: Only 5 Of?p stars have been identified in the Galaxy. Of these, 3 have been studied in detail, and within the past 5 years magnetic fields have been detected in each of them. The observed magnetic and spectral characteristics are indicative of organised magnetic fields, likely of fossil origin, confining their supersonic stellar winds into dense, structured magnetospheres. The systematic detection of magnetic fields in these stars strongly suggests that the Of?p stars represent a general class of magnetic O-type stars.

Fractal analysis of fisheries and environmental time series for the development of early warning indicators
Creators: name: Montes-Aste, Rodrigo Marco
Publisher: name: University of British Columbia
Year: 2015

description: Fractal theory has been used in aquatic sciences to quantify scale-invariant relationships under the form of scaling or power laws, which represent patterns that help to understand the complex structure of exploited marine ecosystems and their populations through time. Fisheries time series are inherently variable and complex because they represent the interaction between population dynamics, oceanographic forcing’s and anthropogenic pressure (exploitation rates). Thus, to better understand the temporal dynamics of fisheries time series under the framework of fractal theory, smooth pink shrimp (Pandalus jordani) daily catch time series, daily sea surface temperature and wind stress time series from the west coast off Vancouver Island were analyzed. The ultimate goal of this thesis was the early detection of changes and critical thresholds levels over which a fishery move to a depleted or unhealthy state. This is a highly desirable objective because it gives fishery managers time to intervene in order to avoid a fishery collapse. I identified fractal patterns in smooth pink shrimp daily catches, sea surface temperature and wind stress time series. Those patterns were quantified through the Hurst coefficient (H), which integrates time series’ long-range dependence and intermittency into a single index. Inter-annual changes in Hurst coefficients from sea surface temperature appear to be related with major oceanographic anomalous conditions such regime shifts and El Niño events. Long-range dependence and intermittency were estimated for catch time series using the fractionally differenced parameter d and the Lévy index α and then combined into a single index (1/LHE indicator). Our proposed indicator, calculated using rolling windows across the history of the fishery, tracks well the vulnerable biomass for all years, which means that it is possible to have an indicator of major changes in the biomass of Pandalus jordani at the beginning and during the progress of each fishing season.
A comparative study of executive functioning behaviours in bilingual and monolingual children with autism spectrum disorder.
Creators: name: Macaro, Stefanie
Publisher: name: University of British Columbia
Year: 2015

description: Weaker Executive Function (EF) abilities have been consistently noted in individuals with an Autism Spectrum Disorder (ASD) relative to typically-developing children, specifically with deficits in planning, mental flexibility or shifting, inhibition, and working memory. There have been mixed findings in terms of typically-developing bilingual individuals demonstrating a bilingual advantage compared to monolingual peers on tasks of EFs. However, there is currently no research comparing the EF skills of bilingual and monolingual children with ASD. The current study compared the parent and teacher ratings of EF deficits and academic achievement in 42 8.5-to-9.0-year-old bilingual and monolingual children with ASD. Results indicated no significant differences in ratings of EF deficits or academic achievement scores. The results from this study support past research that indicates bilingualism does not have a negative impact on the cognitive development of children with ASD.
An Analytical Review of John Kotter's Change Leadership Framework: A Modern Approach to Sustainable Organizational Transformation
Creators: name: Carreño, Adolfo M.
Publisher: name: Adolfo Carreño
Year: 2024

description: John P. Kotter’s 8-Step Change Management Model, first introduced in his 1995 Harvard Business Review article Leading Change: Why Transformation Efforts Fail and further developed in his 1996 book Leading Change, continues to stand as one of the most influential frameworks for guiding organizational transformation. This article revisits Kotter’s model within the context of 2024, where rapid technological advancements, market volatility, and an increasing need for agility are reshaping business landscapes. Kotter’s emphasis on leadership as the central driver of change offers organizations a structured and actionable approach to managing large-scale transformations, addressing common pitfalls like complacency, insufficient vision, and lack of momentum.However, this article also critically examines the limitations of Kotter’s framework, particularly its linearity and potential rigidity in fast-paced, technology-driven environments, as well as its focus on top-down leadership. The analysis explores how modern leadership styles—such as servant, transformational, and adaptive leadership—can complement and enhance Kotter’s model, making it more inclusive and better suited to today’s dynamic demands. Additionally, integrating Agile, Lean, and continuous improvement methodologies allows organizations to achieve the flexibility necessary to thrive in a rapidly evolving market.Through real-world case studies of both successful and unsuccessful applications, this article provides insights into how organizations can adapt Kotter’s framework to their specific needs. Ultimately, it argues that while Kotter’s structured approach remains a powerful foundation for change, incorporating modern leadership practices and fostering agility are crucial for addressing the challenges of both the present and the future.

We study the relevance of nonextensive statistical effects on the beta-stable equation of state at fixed entropy per baryon, in presence and in absence of trapped neutrinos, for nucleonic and hyperonic matter. We show that nonextensive statistical effects could play a crucial role in the structure and in the evolution of the protoneutron stars also for small deviations from the standard Boltzmann-Gibbs statistics.

description: To understand how planetary systems form in the dusty disks around pre-main-sequence stars a detailed knowledge of the structure and evolution of these disks is required. While this is reasonably well understood for the regions of the disk beyond about 1 AU, the structure of these disks inward of 1 AU remains a puzzle. This is partly because it is very difficult to spatially resolve these regions with current telescopes. But it is also because the physics of this region, where the disk becomes so hot that the dust starts to evaporate, is poorly understood. With infrared interferometry it has become possible in recent years to directly spatially resolve the inner AU of protoplanetary disks, albeit in a somewhat limited way. These observations have partly confirmed current models of these regions, but also posed new questions and puzzles. Moreover, it has turned out that the numerical modeling of these regions is extremely challenging. In this review we give a rough overview of the history and recent developments in this exciting field of astrophysics.

The longitudinal magnetic field of this star is detected consistently, but it is not observed to vary strongly, during nearly 5 years of observation. In this poster we evaluate whether the nearly constant longitudinal field is due to intrinsically slow rotation, or rather if the stellar or magnetic geometry is responsible.

description: The Beam Conditions and Radiation Monitoring System, BRM, is implemented in CMS to protect the detector and provide an interface to the LHC. Seven sub-systems monitor beam conditions and the radiation level inside the detector on different time scales. They detect adverse beam conditions, facilitate beam tuning close to CMS, and measure the doses accumulated in different detector components. Data are taken and analysed independently of the CMS data acquisition, displayed in the control room, and provide inputs to the trigger system and the LHC operators. In case of beam conditions dangerous to the CMS detector, a beam abort is induced. The Fast Beam Conditions Monitor, BCM1F, is a flux counter close to the beam pipe inside the tracker volume. It uses single-crystal CVD diamond sensors, radiation-hard FE electronics, and optical signal transmission to measure the beam halo as well as collision products bunch by bunch. The system has been operational during the initiatory runs of LHC in September 2008. It works reliably since the restart in 2009 and is invaluable to CMS for everyday LHC operation. A characterisation of the system on the basis of data collected during LHC operation is presented.

Effect of the biceps Brachii tendon on elbow flexor force steadiness in men and women
Creators: name: Lizu, Afruna
Publisher: name: University of British Columbia
Year: 2015

description: Tendons are connective tissue that transmit force to the skeleton. Therefore, mechanical and material properties of the tendon, such as stiffness, strain, stress and Young’s Modulus likely influence force production and control. Men are steadier than women in maintaining isometric elbow flexion force, but the cause of this sex-related difference in force steadiness (FS) has not been established. To-date most FS studies have centred on absolute force as well as motor unit activity, with limited attention given to the interaction between muscle and tendon. The purpose of this study was to determine whether the mechanical properties of tendon differ between men and women, and whether this contributes to men being steadier than women. Ten men (23 ± 4years) and 10 women (22 ± 3years) who were healthy and recreationally active participated in a single session to evaluate maximal force, steadiness and tendon properties. Submaximal forces of 2.5%, 5%, 10%, 20%, 40% and 60% maximum voluntary contraction (MVC) were executed and FS as well as tendon properties were measured during these efforts. Contractions were randomized within and between individuals for the submaximal isometric elbow flexion contractions. All measures were undertaken during the 5 second steady state contraction executed in a neutral wrist position. Results indicated that men were significantly stronger (p < 0.001), steadier (p < 0.001) and the BB tendon was stiffer (p = 0.03) in men than women. Tendon stiffness and CV of force were strongly correlated (r² = 0.60; r = 0.77; p < 0.001) for women but moderately correlated (r² = 0.21; r = 0.46; p < 0.001) for men. Therefore, our results suggest that having a more compliant BB tendon is likely a contributing factor of less stability in the elbow flexors of women compared to men.
Carbon management in airports
Creators: name: Cohen, Yaron
Publisher: name: University of British Columbia
Year: 2015

description: Airports are multi-stakeholder organizations that can be as complex to manage as small cities. Carbon emissions have begun to occupy an important place in airport environmental management plans. Proposed solutions to reduce carbon emissions from airports’ landside and airside operations are diverse and contain different courses of action for emission sources located both on the ground and in the air. However, due to the complexity of airport governance, the implementation of carbon management policy faces technical, financial, and organizational challenges. Buildings, ground fleets, and ground support equipment (GSE) used at airports tend to be owned by different parties, including airlines, airports, and third-party sub-contractors, and the lack of coordination among those parties can be a challenge to developing emission-reduction goals. Emission-reduction goals in airports require collaborative environmental management, including emission monitoring, and designated personnel who can supervise the progress of the policy’s implementation. The study conducted for this thesis examined the following topics: · The ways airports report and monitor carbon emissions · Airports’ perceived environmental management priorities · Constraints on carbon management in airports · Currently incorporated elements of collaborative carbon management in airports. The study involved two parts. The first part is a review of current GHG emission reports published by airports, and the second part is an internet-based survey that was sent to airports. The analysis conducted for part 1 (reported in chapter 2) reveals the need for new harmonized GHG reporting standards for airports that better reflect the technological interdependence between airplanes and airports. The findings of part 2 (reported in chapter 3), based on the responses received from airports (n=31), reveal a growing willingness to allocate more resources to reduce carbon emissions in airports, in addition to constraints on carbon management. The constraints are in the form of lack of government regulation that requires airport authorities to engage tenants in the carbon management process, lack of access to tenants’ emission data, and high costs of implementing technological solutions currently available for carbon reduction. The results highlight the importance of developing strategies to address carbon emissions in inter-organizational levels.

description: In this paper, Lipschitz univariate constrained global optimization problems where both the objective function and constraints can be multiextremal are considered. The constrained problem is reduced to a discontinuous unconstrained problem by the index scheme without introducing additional parameters or variables. A Branch-and-Bound method that does not use derivatives for solving the reduced problem is proposed. The method either determines the infeasibility of the original problem or finds lower and upper bounds for the global solution. Not all the constraints are evaluated during every iteration of the algorithm, providing a significant acceleration of the search. Convergence conditions of the new method are established. Test problems and extensive numerical experiments are presented.

Reduction of limonitic laterites by ferrous sulphate in ammoniacal solutions

Publisher: name: University of British Columbia
Year: 2015

description: Leaching of a limonitic laterite (1.49% Ni, 0.33 % Co, 2.29% Mn, 51.8% Fe) using ferrous sulphate as reductant was studied in ammoniacal solutions. Studied parameters included temperature, agitation, ferrous sulphate concentration, solids content, ammonia concentration and a comparison between ammonium sulphate and chloride. Tests were performed in a batch cell with temperatures between 20 and 80ºC at atmospheric pressure. Leaching kinetics for nickel were different to cobalt and manganese. Nickel was favoured by temperature in ammonium sulphate reaching 66% extraction in 3 hours, whereas in ammonium chloride it showed slower but steady kinetics with an extraction of 75% in 24 hours. Cobalt extraction in ammonium sulphate was low at high temperature and solids content; however, at low solids content (4% w/w) and high temperature (80°C) cobalt extraction reached 80% in 4 hours. With 11% solids at the same temperature, extraction decreased to 20%. In presence of ammonium chloride, temperature had a positive impact on cobalt reaching 80% in 8 hours at 23% w/w solids. Cobalt appeared to re-precipitate in presence of ammonium sulphate. Manganese behaved similarly to cobalt, however, in presence of ammonium sulphate, it only reached 60% extraction after 8 hours at 80°C at low solids. In presence of ammonium chloride, manganese reached 65% in 3 hours while increasing solids was not detrimental. Manganese suffered adsorption and/or co-precipitation in ammonium sulphate and chloride. This decrease in extraction exhibited by cobalt and manganese was attributed to co-precipitation and/or adsorption in iron oxides/hydroxides. Nickel extraction appeared aided by ferrous sulphate. Cobalt and manganese improved in presence of higher ammonia/ammonium, agreeing with the observation that cobalt and manganese are more prone to co-precipitation/adsorption; for which they prefer lower ferrous sulphate and higher ammonia/ammonium in order to stabilize their ammines. Feed and solid residue analyses using chemical assays, x-ray diffraction, scanning electron microscopy and mineralogy, provided better understanding of limonite reduction. The main phase in the residue was magnetite. Differences in behaviour between nickel and cobalt/manganese suggest a two-stage process, and chloride solutions seem promising due to better stability of cobalt and manganese.
An Analytical Review of John Kotter's Change Leadership Framework: A Modern Approach to Sustainable Organizational Transformation

Publisher: name: Institute for Change Leadership and Business Transformation
Year: 2024

description: This essay aims to critically evaluate John P. Kotter’s 8-Step Change Leadership Model in the context of modern organizational transformation. The study examines how the framework, originally designed for top-down leadership in structured environments, applies to contemporary challenges such as technological disruption and market volatility. The methodology involves a qualitative review of case studies from healthcare, education, and corporate sectors where Kotter’s model was applied. Cases were selected based on the presence of large-scale transformation efforts, and data were analyzed to assess the effectiveness of Kotter’s linear approach versus more iterative, adaptive methods like Agile and Lean.Results indicate that while Kotter’s model remains useful for initiating change, its rigidity can limit long-term adaptability in fast-paced environments. Successful cases demonstrated early wins and strong leadership, while unsuccessful cases showed resistance and lack of sustained momentum. Integration of Agile and Lean methodologies improved flexibility and responsiveness, contributing to better outcomes.In conclusion, Kotter’s model provides a solid foundation for organizational change, but incorporating adaptive practices is crucial for success in today’s dynamic business landscapes. This research suggests that modernizing Kotter’s framework with iterative and inclusive strategies can better meet the evolving needs of organizations.
Nitrate removal from drinking water using combined ion exchange/ resin bioregeneration
Creators: name: Ebrahimi, Shelir
Publisher: name: University of British Columbia
Year: 2015

description: Nitrate contamination is a drinking water concern in many areas in the world, especially rural communities. Excess nitrate can cause several environmental and health problems. The maximum acceptable concentration of nitrate in drinking water is set to be 45 mg /L as nitrate by USEPA. One of the most common methods for nitrate removal from water is ion exchange using nitrate selective resins. Although these resins have a great capacity for nitrate removal, they are considered non regenerable. The ability to regenerate these resins multiple times will increase the environmental and economic sustainability of nitrate-contaminated water treatment processes. This dissertation tests the hypothesis that multi-cycle exhaustion/ bioregeneration of resin enclosed in a membrane is feasible and temperature and salt concentration in the medium will have an influence on the processes involved. The results showed that this method is an effective and innovative resin regeneration method. Applying 6 cycles of resin exhaustion/ regeneration showed that resin could be used for 4 cycles without a loss of capacity, after 6 cycles only 6% of the capacity was lost. A pseudo-second order kinetic equation described the nitrate desorption analysis well. The initial desorption rates of nitrate from the resin in a membrane were significantly different at different salt concentrations and temperatures; maximum of 306±21 mg of nitrate/g of resin. h for 6% at 35 °C and minimum of 42±3 mg of nitrate/g of resin. h at 2% salt and 12 °C . The effect of different salt concentrations on the biological nitrate removal rate was dependent on the temperature; within each group of temperatures, the nitrate degradation rate decreased with increasing the salt concentration. 𝒓𝒂𝒕𝒆 ( 𝑚𝑔 𝑛𝑖𝑡𝑟𝑎𝑡𝑒/𝑚𝑔 𝑉𝑆𝑆.ℎ𝑟)=0.0102+(0.00114×𝒕𝒆𝒎𝒑𝒆𝒓𝒂𝒕𝒖𝒓𝒆)−(0.000291×𝒔𝒂𝒍𝒕) fit the data for the effect of salt concentration and temperature on nitrate degradation rate with the best correlation (R² = 0.93). The results from the kinetic studies were used to develop a mathematical model which incorporated physical desorption process with biological removal kinetics. The model fit well to experimental data (R²= 0.94±0.06 for 6 bioregeneration cycles) and was applied in the design of a bioreactor for a local nitrate contaminated drinking water source.
Permeable bodies : children, cancer, and biomedicine in Argentina
Creators: name: Wainer, Rafael E.
Publisher: name: University of British Columbia
Year: 2015

description: The vast improvement in survival rates in childhood cancer, especially in childhood leukemia, has expanded expectations of survival. Surviving cancer is the result of invasive and life- disrupting treatments. To understand the long and taxing medical journeys of these children living with cancer this study traces children and families’ experiences at Hospital Infantil (public Children’s Hospital) in the City of Buenos Aires, Argentina. It examines how children and families as well as hematologists, communicable disease specialists, and palliativists struggle with the treatments and care for these children. This thesis asks: How does a “sick child” overcome a life-threatening illness such as a cancer and its painful treatments to become a “cancer survivor” living “life without illness” in the global south, particularly in a country like Argentina? This question leads to an anthropological reflection on the role of the body, especially children’s bodies, in cancer treatment, palliative care, and cure. It pays careful attention to issues of corporeality and subjectivity. The thesis examines how bodies work interactively while being the object of invasive and painful biomedical interventions. These interventions not only affect children but also their families and the professionals themselves. This ethnography investigates the potentials and perils of pediatric cancer treatment in its specific Argentinean context and the importance of carefully looking at the body to understand children, families, and professionals’ practices that aim for a life without cancer. By focusing on the production of “permeable bodies” this study argues that cancer treatment turns children’s bodies into permeable bodies, bodies painfully turned inside out, as a way of producing knowledge and an urgent therapeutic relation that stretches in multiple dimensions. Children become the embodied objects of cancer treatment.

This map is not intended to be used for selecting individual sites. Its purpose is to inform land-use planners, government officials, and the public in a general way about geologic bedrock conditions that affect the selection of sites for various purposes. The properties of thick soils may supercede those of the underlying bedrock and should be considered on a site-to-site basis. At any site, it is important to understand the characteristics of both the soils and the underlying rock.

Using exact diagonalization, we find that for moderate non-Abelian field strengths the system's behaviour resembles a single internal state quantum Hall system, while for stronger fields there is a phase transition to either two internal state behaviour or the complete absence of fractional quantum Hall plateaus. Usually the energy gap is reduced by the presence of a non-Abelian field, but some non-Abelian fields appear to slightly increase the gap of the $ν=1$ and $ν=3/2$ Read-Rezayi states.

Characterizing the role of proteins in modulating microtubule dynamics and cell morphogenesis in Arabidopsis thaliana

description: Microtubules are dynamic polymers that are important for the growth and development of plant cells. Because of their vital role, the dynamics and organization of microtubules need to be tightly modulated by other proteins. The major focus on this dissertation is to elucidate and characterize the role of specific proteins (ARK1, NEK6, MOR1) that are responsible for orchestrating the dynamics and organization of microtubules in the model plant, Arabidopsis thaliana. The motor protein, ARK1, was previously shown to play an important role in root hair morphogenesis but had an unknown role in modulating microtubule dynamics. Moreover, evidence showed that ARK1 physically interacts with the NEK6 kinase, although for an undetermined reason. Based on my data, I determined that ARK1 functions as a plus-end tracking protein that has a specific role in promoting the depolymerization of microtubules. I also discovered that ARK1 has a secondary microtubule-binding domain in addition to the motor domain, which is the canonical microtubule-binding domain. I noted, however, that this secondary microtubule-binding domain is not essential for ARK1’s ability to induce microtubule depolymerization. While NEK6 and ARK1 both modulate microtubule dynamics, I determined that neither protein requires each other for function or localization, suggesting that they operate independently from each other to control microtubule dynamics and cell elongation. In addition, I provided evidence that shows that ARK1 has a putative yet unknown role in controlling NEK6 gene expression. Finally, the microtubule-associated protein MOR1 was confirmed to be a plus-end tracking protein through live-cell imaging of MOR1 fused to a fluorescent reporter (MOR1-3xYpet). In revealing that MOR1 binds to both growing and shrinking microtubule plus ends, my data corroborated previous studies showing reduced microtubule growth and shrinkage in mor1 mutants, and confirm MOR1’s role as a microtubule polymerase. Comparing MOR1-3xYpet live-cell imaging with previous experiments using fixed samples revealed that the chemical fixation process affects the plus-ends of microtubules, stressing the importance of using non-fixed samples for the most accurate results. My dissertation thus expands our knowledge about how microtubule dynamics and organization is controlled in plant cells by three distinct proteins.
Design and simulation of a coded sequence ground penetrating radar

description: In the context of climate change, ground water monitoring has become an important task for which Ground Penetrating Radar (GPR) has been ideally suited. However, the limited depth of investigation has prevented GPR’s use in situations with deep water tables. In order to meet these new depth objectives, a novel Radar has been designed. This new radar, marries modern digital coding techniques and the ever improving field of digital electronics with that of a prototypical GPR. The sequences chosen for investigation include Golay-codes and M-sequences. This new GPR uses off the shelf digital equipment to meet these demands and does so in a more cost effective manner than conventional GPR. The design and implementation of this radar is covered. Simulations of theoretical performance are included for both code types and include factors for both white noise and digitizer quantization. Preliminary results demonstrate that the use of digital codes allow for greater dynamic range above and beyond that afforded by an impulse radar. Specifically, we show that when used with pre-existing dynamic range Golay-codes can add an additional 50 dB of dynamic range. Contrarily, we show that M-sequences can provide a similar dynamic range but this is total and not in addition to receiver sensitivity. In both cases, however, we achieve total dynamic ranges greater than that of an impulse radar. According to the simulation, the increase in dynamic range from the sequences, combined with a lower frequency of radar (25 MHz), allow us to achieve previously unseen depths of investigation (180 m). This depth is under a presumed attenuation of 1 dB m −¹ . As an additional benefit of using these codes, we can exploit the use of commercial FPGAs for code generation and processing. This substantially reduces the cost and opens up the radar for the intended application of remote monitoring. This lower frequency has the adverse effect of lowering the radar’s resolution. Moreover, the use of long codes increases the device’s acquisition time. However, these limitations do not unduly impact its intended use.

description: In the recent world, security is a prime important issue, and encryption is one of the best alternative way to ensure security. More over, there are many image encryption schemes have been proposed, each one of them has its own strength and weakness. This paper presents a new algorithm for the image encryption/decryption scheme. This paper is devoted to provide a secured image encryption technique using multiple chaotic based circular mapping. In this paper, first, a pair of sub keys is given by using chaotic logistic maps. Second, the image is encrypted using logistic map sub key and in its transformation leads to diffusion process. Third, sub keys are generated by four different chaotic maps. Based on the initial conditions, each map may produce various random numbers from various orbits of the maps. Among those random numbers, a particular number and from a particular orbit are selected as a key for the encryption algorithm. Based on the key, a binary sequence is generated to control the encryption algorithm. The input image of 2-D is transformed into a 1- D array by using two different scanning pattern (raster and Zigzag) and then divided into various sub blocks. Then the position permutation and value permutation is applied to each binary matrix based on multiple chaos maps. Finally the receiver uses the same sub keys to decrypt the encrypted images. The salient features of the proposed image encryption method are loss-less, good peak signal-to-noise ratio (PSNR), Symmetric key encryption, less cross correlation, very large number of secret keys, and key-dependent pixel value replacement.

Teacher candidates’ imaginative capacity and dispositions toward using ICT in practice
Creators: name: Arntzen, Jenny
Publisher: name: University of British Columbia

description: The study investigated the relationship between instructional discourses in a pre-service teacher education program and teacher candidates’ subsequent plans to use ICT in their professional practice. Teacher candidates’ dispositions, in terms of comportment and composure, were seen as indicative of the quality of their relationship with ICT. Teacher candidates’ manifestations of these dispositions, in terms of ICT imaginative capacity, were seen as indicative of the characteristics of their use (what they had the capacity to imagine and the capability to implement). Manifestations of dispositions were described as displays of ICT imaginative capacity. The setting for the study was a post-baccalaureate two-year teacher education program in a large regional university in western Canada. Participants in the study were comprised of a thirty-eight member cohort of teacher candidates in the first year of their two-year program. A sub-group of teacher candidates was self-selected from the cohort and participated in a research intervention. This study adapted a social constructivist theoretical framework complemented by an enactive analysis of social interactions examining communicative events from the teacher education program. An interpretive case study methodology collected data from teacher education classes, teacher candidate questionnaires, and focus group discussions. These three datasets were analyzed and interpreted to explore relationships between instructional discourses and teacher candidates’ dispositions toward using ICT. Findings document teacher candidates’ dispositions toward using ICT as demonstrated by their capacity to imagine using ICT and their capability to implement these imaginings in practice. Conclusions suggest a need for further research into “ecologies of learning”. Recommendations also include a need to investigate instructional discourses with regards to developing ICT imaginative capacity and imaginative capability. The need to develop imaginative capacity extends beyond when, where, why, how, or what ICT teachers learn to use in practice.

description: We consider an open bipartite quantum system with dissipative Lindblad type dynamics. In order to study the entanglement of the stationary states, we develop a perturbative approach and apply it to the physically significant case when a purely dissipative perturbation is added to the unperturbed generator which by itself would produce reversible unitary dynamics.
