description: Introduction The diagnostic potential of optical coherence tomography (OCT) in neurological diseases is intensively discussed. Besides the sectional view of the retina, modern OCT scanners produce a simultaneous top-view confocal scanning laser ophthalmoscopy (cSLO) image including the option to evaluate retinal vessels. A correct discrimination between arteries and veins (labeling) is vital for detecting vascular differences between healthy subjects and patients. Up to now, criteria for labeling (cSLO) images generated by OCT scanners do not exist. Objective This study reviewed labeling criteria originally developed for color fundus photography (CFP) images. Methods The criteria were modified to reflect the cSLO technique, followed by development of a protocol for labeling blood vessels. These criteria were based on main aspects such as central light reflex, brightness, and vessel thickness, as well as on some additional criteria such as vascular crossing patterns and the context of the vessel tree. Results and Conclusion They demonstrated excellent inter-rater agreement and validity, which seems to indicate that labeling of images might no longer require more than one rater. This algorithm extends the diagnostic possibilities offered by OCT investigations.
Parity bit selected spreading sequences for spread spectrum and code division multiple access systems

description: Systematic block codes compute (n-k) parity bits for an information block of k bits, and append the parity bits to the end of the information bits to form an n-bit codeword. This redundancy provides certain ability for the receiver to detect or correct a limited number of errors caused by noise and interference on the channel. In direct sequence spread spectrum (DS-SS) communication systems, the information is spread over a large bandwidth by multiplying the information bits with a high rate pseudonoise (PN) sequence. In this thesis, these two techniques are combined to create a new technique, named parity bit selected direct sequence code division multiple access (parity bit selected DS-CDMA). The proposed scheme uses the (n-k) parity bits to select one of 2 (n-k) mutually orthogonal PN sequences. Then the selected PN sequence is used to spread each bit in the information block of k bits. But the (n-k) parity bits are not appended to the end of the information bits, and are not transmitted to the receiver. The receiver can obtain the parity bits by using 2(n-k) matched filters to determine which PN sequence is used for an information block of k bits. Then the errors can be corrected by employing a decoding algorithm. Block codes with different lengths are considered in our simulation in order to find which one is best for the proposed scheme at a given Eb/No. The simulation results in a multi-user environment show that the proposed parity bit selected DS-CDMA system can provide better BER performance than both the uncoded DS-CDMA and the block coded DS-CDMA systems.

description: Increasing prevalence of depression poses a huge challenge to the healthcare systems, and the success rates of current standard therapies are limited. While 30% of treated patients do not experience a full remission after treatment, more than 75% of patients suffer from recurrent depressive episodes. Eye Movement Desensitization and Reprocessing (EMDR) therapy represents an emerging treatment option of depression, and preliminary studies show promising effects with a probably higher remission rate when compared to control-therapies such as cognitive behavioral therapy. In the present study, 49 patients with severe depression were treated with an integrated systemic treatment approach including EMDR therapy that followed a specific protocol with a treatment algorithm for depression in a naturalistic hospital setting. Following their discharge from the hospital, the patients were followed up by a structured telephone interview after 3 and 12 months. 27 of the 49 (55%) patients fulfilled the Beck’s depression criteria of a full remission when they were discharged. At the follow-up interview, 12 months after discharge, 7 of the 27 patients (26%) reported a relapse, while the remaining 20 patients (74%) had stayed relapse-free. The findings of our observational study confirm reports of earlier studies in patients with depression, showing that EMDR therapy leads to a high rate of remission, and is associated with a decreased number of relapses. Patients with depression receiving EMDR treatment may be more resilient to stressors.

description: Background:
Engineered nanomaterials (ENMs) are marketed as a substance or mixtures and are additionally used due to their active agent properties in products such as pesticides or biocides, for which specific regulations apply. Currently, there are no specific testing strategies for environmental fate and effects of ENMs within the different regulations. An environmental test and risk assessment strategy for ENMs have been developed considering the general principles of chemical assessment.
Results:
The test strategy has been developed based on the knowledge of national and international discussions. It also takes into account the conclusions made by the OECD WPMN which held an expert meeting in January 2013. For the test strategy development, both conventional and alternative endpoints were discussed and environmental fate and effects were addressed separately.
Conclusion:
A tiered scheme as commonly used in the context of precautionary environmental risk assessment was suggested including the use of mathematical models and trigger values to either stop the procedure or proceed to the next tier. There are still several gaps which have to be filled, especially with respect to fate, to develop the test strategy further. The test strategy features a general approach. It is not specified to fulfil the information requirements of certain legislation (e.g. plant protection act, biocide regulation, REACH). However, the adaption of single elements of the strategy to the specific needs of certain legislation will provide a valuable contribution in relation to the testing of nanomaterials.Quelle: http://enveurope.springeropen.com/

description: Bacterial pneumonia is a major cause of acute lung injury and acute respiratory distress syndrome, characterized by alveolar barrier disruption. NLRP3 is best known for its ability to form inflammasomes and to regulate IL- 1β and IL-18 production in myeloid cells. Here we show that NLRP3 protects the integrity of the alveolar barrier in a mouse model of Streptococcus pneumoniae-induced pneumonia, and ex vivo upon treatment of isolated perfused and ventilated lungs with the purified bacterial toxin, pneumolysin. We reveal that the preserving effect of NLRP3 on the lung barrier is independent of inflammasomes, IL-1β and IL-18. NLRP3 improves the integrity of alveolar epithelial cell monolayers by enhancing cellular adherence. Collectively, our study uncovers a novel function of NLRP3 by demonstrating that it protects epithelial barrier function independently of inflammasomes.

description: This research study aims to evaluate the applicability of utilizing Polyethylene terephthalate plastic waste blends with Recycled Concrete Aggregates and Crushed Bricks as sustainable materials for road base/subbase and footpath applications. The study comprises four stages; unbound, cement-stabilization, geopolymer-stabilization and field study of concrete footpath with recycled materials. The geotechnical properties of plastic/demolition waste blends were evaluated and theoretical model parameters were developed at each laboratory stage. Moreover, the strength and durability parameters of the field footpath were evaluated. The research outcome can be used to divert significant amount of waste materials from landfills and into sustainable pavement construction.

description: Test data preparation phase for testing database applications deals with instantiating program variables, as well as generating database instance(s) to run application queries on these instances. We first propose a method that takes a database schema, a test case representing a sequence of simple queries on a path within a transaction in a given database application, and corresponding properties associated with these queries; forms a Constraint Satisfaction Problem (CSP) by considering the interactions among the queries and the integrity constraints given by the schema; and generates, by solving this CSP, an initial database instance which satisfies the property associated with each query and is consistent with respect to the integrity constraints given in the schema. Then, we extend this method by taking a sequence of test cases containing nested queries, and generate one or more consistent database instances that satisfy the properties of queries in each test case in the given sequence of test cases. We also discuss how to integrate our method in an approach given in the literature which instantiates the input host variables of queries automatically.

Identification and characterization of the type 1 diabetes-related wheat storage globulin WP5212.

Subjects: subject: Chemistry, Biochemistry.

description: Type 1 diabetes (T1D) affects approximately 200,000 Canadians and is increasing at a rate of about 3.0% per year. The development of autoimmune diabetes requires genetic susceptibility and is influenced by environmental agents. Diets in which wheat protein is the sole amino acid source are associated with high diabetes frequency in diabetes-prone BioBreeding (BBdp) rats and non-obese diabetic (NOD) mice, two models of spontaneous autoimmune diabetes. We hypothesized that an abnormal immune response to wheat, as indicated by circulating IgG antibodies, could be used to identify T1D-related wheat proteins. Similar methods have been used to identify the diabetes-related autoantigens. A wheat cDNA expression library was immunoscreened with pooled IgG antibodies from wheat gluten-fed diabetic BBdp rats. Initially, three clones were isolated. When the proteins were screened with sera from individual rats at varying risk of disease, antibody reactivity to clone WP5212, a wheat storage globulin, was strongest in diabetic rats. This antibody reactivity was not only associated with disease but also closely correlated with islet damage. Additional studies revealed that WP5212 antibodies were linked to diabetes in NOD mice and, remarkably, in human T1D patients. Furthermore, patients with both T1D and the wheat sensitive enteropathy, celiac disease (CD), displayed high WP5212 antibody reactivity, possibly representing a marker of the predisposition of T1D patients to develop CD. WP5212 shared homology with a number of dietary proteins and allergens, suggesting that diabetes-promoting structures could exist in other food plants and that immunomodulatory molecules could interact with the immune system by a common mechanism. WP5212 also shared homology with self proteins, which could act as a means for the initiation or promotion of autoimmunity. WP5212 is the first candidate dietary wheat protein implicated in the development of diabetes. Thus, screening a cDNA expression library provides a novel approach that permits the identification of environmental antigens involved in autoimmune diseases. The evidence suggests that WP5212 is strongly antigenic in three separate species that develop spontaneous diabetes. The molecular identity of this immune-targeted dietary wheat protein will help elucidate the pathogenic mechanisms by which wheat-related diabetes occurs.

description: A 0.17 mM NaCl droplet on X100 pipeline steel covered by paraffin oil is used to simulate the corrosive environment encountered in heavy oil or bitumen pipelines. The development of corrosion under the droplet was monitored and explored in two stages. In the initial stage (1 h), the distribution of corrosion pits was heterogeneous with one area under the droplet presenting a higher pit density. As the corrosion proceeded (24 h), the localized corrosion in the area under the droplet with the higher pit density switched to general corrosion, while the other region of the droplet continued to pit. The mechanisms driving this new distinctive corrosion form developed beneath an underoil salty droplet on X100 pipeline steel are explained.
Petrology of the Gracefield pluton.
Creators: name: Durocher, Marcel Elzear.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1977
Subjects: subject: Geology.

description: The Gracefield pluton is composed of two distinct syenite intrusions; both of which appear to have been intruded late in the Grenville tectonic and metamorphic history. They both exhibit a well developed concentric mineralogical zoning. They have shonkinitic cores which grade laterally into alkali syenite. The larger (earlier) intrusive is locally transitional to nepheline syenite along the south margin. The temperature of mineral equilibration of the nepheline-bearing syenite was determined to be 730°C. The temperature of the magma at the time of intrusion was somewhat higher. If the oxygen fugacity during the crystallization history of the early intrusive was close to that of the QFM buffer, the fugacity of water was between 302 and 1950 bars. The silica activity in the magma was low during crystallization. The two intrusives are mineralogically, chemically, and texturally similar. They also appear to have had similar crystallization histories. It is highly probable that the temperature of intrusion, oxygen and water fugacities, and silica activity in the later intrusive, were in the same range as those in the early intrusive. The mineralogical zoning in the intrusives is due to the operation of convection cells during the early parts of their crystallization histories. Shortly after emplacement of a largely liquid magma, salite, apatite, and minor amounts of magnetite and ilmenite started crystallizing along the walls of the magma chamber. These crystals were then concentrated in the lower part of the magma chamber by slow moving convection cells. This resulted in an alkalic magma in the upper part of the chamber, and a crystal mush in the lower part. After convection ceased, crystallization of the feldspars, barkevikite, biotite, most of the magnetite, and nepheline and calcite commenced in the larger intrusive.

description: Foundations in coastal structures are subject to geomorphological and hydrological changes which can result in serviceability issues. This research studies the effect of repetitive water level changes on a soft clay slope. Centrifuge model studies were carried to study the soil movements and pore pressures within a slope subject to fluctuating water level changes. Results shows that piles and pile groups at different locations along the slope experiences bending moments and pile head movements. A fully coupled flow deformation model is presented which is used to back analyse centrifuge results and can be used to analyse such complex problems.

description: Autism spectrum disorders (ASDs) are characterized by repetitive behaviors and impairments of sociability and communication. About 1% of ASD cases are caused by mutations of SHANK3, a major scaffolding protein of the postsynaptic density. We studied the role of SHANK3 in plastic changes of excitatory synapses within the central nervous system by employing mild traumatic brain injury (mTBI) in WT and Shank3 knockout mice. In WT mice, mTBI triggered ipsi- and contralateral loss of hippocampal dendritic spines and excitatory synapses with a partial recovery over time. In contrast, no significant synaptic alterations were detected in Shank3∆11−/− mice, which showed fewer dendritic spines and excitatory synapses at baseline. In line, mTBI induced the upregulation of synaptic plasticity-related proteins Arc and p-cofilin only in WT mice. Interestingly, microglia proliferation was observed in WT mice after mTBI but not in Shank3∆11−/− mice. Finally, we detected TBI-induced increased fear memory at the behavioral level, whereas in Shank3∆11−/− animals, the already-enhanced fear memory levels increased only slightly after mTBI. Our data show the lack of structural synaptic plasticity in Shank3 knockout mice that might explain at least in part the rigidity of behaviors, problems in adjusting to new situations and cognitive deficits seen in ASDs.

description: Multiple myeloma is a bone marrow plasma cell tumor which is supported by the external growth factors APRIL and IL-6, among others. Recently, we identified eosinophils and megakaryocytes to be functional components of the micro- environmental niches of benign bone marrow plasma cells and to be important local sources of these cytokines. Here, we investigated whether eosinophils and megakaryocytes also support the growth of tumor plasma cells in the MOPC315.BM model for multiple myeloma. As it was shown for benign plasma cells and multiple myeloma cells, IL-6 and APRIL also supported MOPC315.BM cell growth in vitro, IL-5 had no effect. Depletion of eosinophils in vivo by IL-5 blockade led to a reduction of the early myeloma load. Consistent with this, myeloma growth in early stages was retarded in eosinophil-deficient ΔdblGATA-1 mice. Late myeloma stages were unaffected, possibly due to megakaryocytes compensating for the loss of eosinophils, since megakaryocytes were found to be in contact with myeloma cells in vivo and supported myeloma growth in vitro. We conclude that eosinophils and megakaryocytes in the niches for benign bone marrow plasma cells support the growth of malignant plasma cells. Further investigations are required to test whether perturbation of these niches represents a potential strategy for the treatment of multiple myeloma.

description: Rainwater tanks provide a range of social, economic and environmental benefits through their water saving and stormwater management capacity. This study constructed a holistic analysis of rainwater tank performance based upon an analysis of the fundamental mechanics of techniques used across the different aspects of hydrology. This new model combined previously incompatible modelling techniques from different hydrological areas of study into a single multi-objective analysis. This holistic assessment allowed the full benefit of these systems to be quantified and optimised with benefits for water supply reliability, local drainage design, catchment flood mitigation and the health of local waterways.

description: Le but de cette thèse est de faire une analyse de l'origine et du fonctionnement de la gestion mondiale du risque de désastres en prenant comme étude de cas la Stratégie internationale pour la prévention des catastrophes naturelles (SIPC). Le cadre théorique donne les définitions les plus courantes des concepts importants de la thèse, c'est-à-dire désastre, risque et mondialisation et il cherche à analyser deux courants sociologiques, le constructivisme et le réalisme, que l'on retrouve souvent à l'intérieur de la sociologie du risque. Plus précisement, la thèse cherche à exposer la confusion que l'on retrouve dans la sociologie du risque par rapport à ces deux courants afin de l'éliminer. Ensuite la thèse présente une description de l'origine et du fonctionnement de la Stratégie internationale pour la prévention des catastrophes naturelles (SIPC). On y retrouve une description historique de, premièrement, la construction de l'ONU au sein de laquelle la Stratégie a été créée et, deuxièmement, de la Décennie internationale pour la prévention des catastrophes naturelles qui la précédait. La thèse analyse l'origine et les outils conceptuels de la SIPC en utilisant les théories expliquées dans les chapitres précédants. En fait, on utilise la théorie de la naissance de la "société à risque" d'Ulrich Beck pour expliquer comment et pourquoi la SIPC existe. De plus, on analyse les concepts de la SIPC à la lumière des théories constructivistes et réalistes. Finalement, on y précise les réalisations et les limites de cette section de l'ONU. La conclusion tire les implications théoriques de la thèse et termine par soulever des pistes pour les recherches futures.

description: Background: Cross‐sectional studies suggested that allergy prevalence in childhood is higher in boys compared to girls, but it remains unclear whether this inequality changes after puberty. We examined the sex‐specific prevalence of asthma and rhinitis as single and as multimorbid diseases before and after puberty onset in longitudinal cohort data. Methods: In six European population‐based birth cohorts of MeDALL, we assessed the outcomes: current rhinitis, current asthma, current allergic multimorbidity (ie, concurrent asthma and rhinitis), puberty status and allergic sensitization by specific serum antibodies (immunoglobulin E) against aero‐allergens. With generalized estimating equations, we analysed the effects of sex, age, puberty (yes/no) and possible confounders on the prevalence of asthma and rhinitis, and allergic multimorbidity in each cohort separately and performed individual participant data meta‐analysis. Findings: We included data from 19 013 participants from birth to age 14‐20 years. Current rhinitis only affected girls less often than boys before and after puberty onset: adjusted odds ratio for females vs males 0.79 (95%‐confidence interval 0.73‐0.86) and 0.86 (0.79‐0.94), respectively (sex‐puberty interaction P = .089). Similarly, for current asthma only, females were less often affected than boys both before and after puberty onset: 0.71, 0.63‐0.81 and 0.81, 0.64‐1.02, respectively (sex‐puberty interaction P = .327). The prevalence of allergic multimorbidity showed the strongest sex effect before puberty onset (female‐male‐OR 0.55, 0.46‐0.64) and a considerable shift towards a sex‐balanced prevalence after puberty onset (0.89, 0.74‐1.04); sex‐puberty interaction: P < .001. Interpretation: The male predominance in prevalence before puberty and the “sex‐shift” towards females after puberty onset were strongest in multimorbid patients who had asthma and rhinitis concurrently.

description: Reading is a transaction, a two-way process, involving a reader and a text at a particular time under particular circumstances (Rosenblatt, 1982). An interest in working with children, and an intrigue in the ways children transact with the stories they hear and/or read has turned me into a "Storycatcher" (Baldwin, 2005). As a storycatcher-researcher, I ventured into the world of stories at the Ottawa Public Library in order to exp-lore the narrative transactions of children between the ages of 3 and 6 years old. My Storycatching is a narrative within a narrative because my focus is on the four (4) child-storytellers' verbal and pictorial narratives, as they embody the literary transactions between themselves, their imaginations, and their live(d) experiences in response to the stories they hear during storytimes at the library.

description: Radar simulations of human targets can be deployed to reduce the measurement effort linked to dataset generation for tasks such as gesture or activity classification. However, simulations require realistic human motion data in order to capture the dynamics of the simulated activities. For this purpose, this paper proposes a stereo camera-based system that enables simultaneous recording of radar data and the corresponding human pose ground truth. By introducing a camera-radar calibration procedure, the 3D human poses and the radar system are synchronized both in time and space. Thus, the system enables the one-by-one re-simulation of the captured measurements for the investigation of simulation quality or sensor studies. The performance of the calibration procedure and the feasibility of direct re-simulations is shown with measurements of an exemplary gesture. In addition, the straightforward extension of the proposed approach to radar sensor networks is demonstrated.

description: This study explores the political discourse on women in prison and the issue of co-corrections in Canada. Tentative propositions were generated regarding the nature of the official rhetoric, feminist position and female inmates' perspective on the treatment of Canadian female prisoners and the issue of shared services. First, provisional generalizations were developed through a review of the American literature dealing with female imprisonment and co-corrections in the United States. Subsequently, through an analysis of the major Canadian penitentiary reports, official female offender reports, relevant parliamentary debates, and an interview with a group of women in P4W, the generalizations were tested against the Canadian context. An effort has been made to develop a substantive theory of the political discourse on women in prison and the issue of co-corrections in Canada. Generally, the tentative framework generated through the analysis of the American literature and the debates on co-corrections in the United States was validated. Some peculiar Canadian features, however, did prompt a revision of the original 'model'. (Abstract shortened by UMI.)

description: Objectives: In this qualitative study, we examined older adults’ experiences of taking part in two 2 efficacious group-based physical activity programs as part of the GrOup-based physical Activity for 3 oLder adults (GOAL) randomized controlled trial. 4 Method: In the GOAL Trial, 627 older adults were randomized to one of three conditions: similar 5 age same gender (SASG), similar age mixed gender (SAMG), or ‘standard’ mixed age mixed 6 gender (MAMG) control exercise group conditions. Participants in this qualitative study (N = 31; 7 Nmen = 17, Nwomen = 14; Mage = 70 years) were purposively sampled from the two experimental 8 conditions (SASG, SAMG) and involved in semi-structured interviews. The data were analyzed 9 using thematic analysis. 10 Results: The results included 12 lower-order and three higher-order themes that reflected (a) the 11 benefits and challenges of exercising with peers, (b) the group as a means of mitigating social 12 isolation, and (c) group exercise and the physically active body. 13 Discussion: Findings highlight the importance of social connections that exist within the age-14 matched physical activity programs, as well as some of the challenges for older adults participating 15 in community-based physical activity programs. Implications for intervention, program planning, 16 and future research are discussed.

The dynamics of polarization in communication fiber

description: Here a temperature stable optical fiber current sensor based on the Sagnac loop interferometer and a cavity formed from two Faraday rotation mirrors is developed and tested. To the best of the author's knowledge a cavity composed of two Faraday rotation mirrors has never been used for the measurement of alternating currents. For the first time, it is shown that the maximum Faraday rotation angle for a long, static optical fiber is input polarization insensitive. Also, linear birefringence is shown to quench this angle in long optical fiber. The polarization dynamics in an optical ground wire network, for a summer period and a fall period, are reported for the first time. The highest-speed polarization changes are attributed to the high-voltage power line, i.e., the electrical current. A novel spectral analysis polarization optical time domain reflectometry method, that uses an induced birefringent event, is shown to work in long optical fiber.

L'identification aux groupes sociaux en milieu de travail: Un regard sur la resolution de conflits dans la perspective de Thomas-Kilmann

description: Les organisation de travail contemporaines sont marquees par diversite des groupes sociaux, qu'ils soient issus de la culture, du sexe ou de l'age. Un tel phenomene se repercute quant a la vision du monde du travail tout autant qu'a la resolution des coflits en milieu de travail. C'est dans ce contexte de diversite que la presente etude avait pour objet, une nouvelle analyse du modele de resolution de conflits de Thomas-Kilmann (1974). Ce modele a ete analyse dans la perspective de l'identification a differents groupes sociaux (age sexe et statut professionnel) et de l'incidence de cette identification sur les dynamiques de conflits au travail. Les resultats d'analyse d'un sondage par questionnaire (n = 60) et d'entrevues semi-dirigees (n = 6) suggerent que la majorite des travailleurs de cette entreprise privilegient le mode de resolution de conflits " compromis " et s'identifient le plus fortement au groupe social " sexe " qu'a ceux bases sur l'age et le statut. En ce qui concerne les styles de resolution de conflits en lien avec le sexe des travailleurs, l'age et le statut professionnel, il semble que les facons de faire traditionnelles persistent: les hommes optent davantage que les femmes pour le mode " competition ", les subalternes privilegient des styles de resolution de conflits moins agressifs que les gestionnaires et la generation Y percoit les plus vieux comme moins enclins aux changements et aux innovations.

description: Background: Patients with vestibular schwannomas (VS) are faced with complex management decisions. Watchful waiting, surgical resection, and radiation are all viable options with associated risks and benefits. We sought to determine if patients with VS experience decisional conflict when deciding between surgery or non-surgical management, and factors influencing the degree of decisional conflict. Methods: A prospective cohort study in two tertiary ambulatory skull-base clinics was performed. Patients with newly diagnosed or newly growing vestibular schwannomas were recruited. Patients were given a demographic form and the decisional conflict scale (DCS), a validated measure to assess the degree of uncertainty when making medical decisions. The degree of shared decision making (SDM) experienced by the patient and physician were assessed via the SDM-Q-10 and SDM-Q-Doc questionnaires, respectively. Non-parametric statistics were used. Questionnaires and demographic information were correlated with DCS using Spearman correlation coefficient and Mann-Whitney U. Logistic regression was performed to determine factors independently associated with DCS scores. Results: Seventy-seven patients participated (55% female, aged 37–81 years); VS ranged in size from 2 mm–50 mm. Significant decisional conflict (DCS score 25 or greater) was experienced by 17 (22%) patients. Patients reported an average SDM-Q-10 score of 86, indicating highly perceived level of SDM. Physician and patient SDM scores were weakly correlated (p = 0.045, Spearman correlation coefficient 0.234). DCS scores were significantly negatively correlated with a decision to pursue surgery, presence of a trainee, and higher SDM-Q-10 score. DCS was higher with female gender. Using logistic regression, the SDM-Q-10 score was the only variable associated with significantly reduced DCS. Conclusions: About one fifth of patients deciding how to manage their vestibular schwannoma experienced a significant degree of decisional conflict. Involving the patients in the process through shared decision-making significantly reduced the degree of uncertainty patients experienced.
Accelerating the scalar multiplication on genus 2 hyperelliptic curve cryptosystems

description: Elliptic Curve Cryptography (ECC) was independently introduced by Koblitz and Miller in the eighties. ECC requires shorter sizes of underlying finite fields in comparison to other public key cryptosystems such as RSA, introduced by Rivest, Shamir and Adleman. Hyperelliptic curves, a generalization of elliptic curves, require decreasing field size as genus increases. Hyperelliptic curves of genus g achieve equivalent security of ECC with field size 1/g times the size of field of ECC for g ≤ 4. Recently, a lot of research is being focused on increasing the efficiency of hyperelliptic curve cryptosystems (HECC). The most time consuming operation in HECC is the scalar multiplication. At present, scalar multiplication on HECC over prime fields under performs in terms of computational time compared to ECC of equivalent security. This thesis focuses on optimizing HECC scalar multiplication at the point arithmetic level. At the point arithmetic level we obtain more efficient doubling and mixed addition operations to decrease the computational time in the scalar multiplication using binary expansions of scalars. In addition, we introduce tripling operations for the Jacobians of hyperelliptic curves to make use of multibase representations of scalars that are being used effectively in ECC. We also develop double-add operations for semi-affine coordinates and Lange's new coordinates. We use these double-add operations to improve the computational cost of precomputation for semi-affine coordinates and that of more important main phase of scalar multiplication for semi-affine coordinates and Lange's new coordinates. We derive special addition to improve the cost of precomputation for Lange's new coordinates and projective coordinates.
