Construction Schemes and their applications

Construction schemes and their applications Fulgencio Lopez Doctor of Philosophy Graduate Department of Mathematics University of Toronto 2018 We study capturing construction schemes, a new combinatorial tool introduced by Todorčević to build uncountable structures. It consists of a ranked family of finite sets that provides a framework to do recursive constructions of uncountable objects by working with finite amalgamations of finite isomorphic substructures, the uncountable substructures of the final object can be further study using capturing. In this Thesis we study the consistency of capturing construction schemes, and related definitions, we prove results of consistency, and give several applications of this tool both to infinite combinatorics and Banach space theory. For example, we show weaker forms of capturing, such as n-capturing, form a strict hierarchy which is related to the m-Knaster Hierarchy. We also show how capturing construction schemes can be used in constructing Suslin trees and Hausdorff gaps of a special kind in an intuitive manner. And give some applications to the theory of nonseparable Banach spaces.
Secure‐aware and privacy‐preserving electronic health record searching in cloud environment

Cloud storage has become a trend of storage in modern age. The cloud‐based electronic health record (EHR) system has brought great convenience for health care. When a user visits a doctor for a treatment, the doctor may be necessary to access the history health records generated at other medical institutions. Thus, we present a secure EHR searching scheme based on conjunctive keyword search with proxy re‐encryption to realize data sharing between different medical institutions. Firstly, we propose a framework for health data sharing among multiple medical institutions based on cloud storage. We explore the public key encryption with conjunctive keyword search to encrypt the original data and store it in the cloud. It ensures data security with searchability. Furthermore, we adopt the identity‐based access control mechanism and proxy re‐encryption scheme to guarantee the legitimacy of access and the privacy of the original data. Generally speaking, our work can achieve authentication, keyword privacy, and privacy preservation. Moreover, the performance evaluation shows that the scheme can achieve high computational efficiency.
Cooperative Evolutionary Framework With Focused Search for Many-Objective Optimization

When dealing with many-objective optimization problems, Pareto-based approaches suffer from the loss of selection pressure toward Pareto front. In this study, a general cooperative evolutionary framework with focused search is proposed to make Pareto-based approaches perform better for many-objective optimization problems. The proposed framework has two evolutionary populations, a focused evolutionary population and a Pareto-based evolutionary population, and these two populations work collaboratively. The focused evolutionary population focuses on searching for the corner solutions that are important for convergence and spread (focused search), guiding the Pareto-based evolutionary population to evolve toward the Pareto front, and promoting Pareto-based evolutionary population to spread along the Pareto front. Pareto-based evolutionary population aims to obtain the solutions with well convergence and diversity (global search), providing some undeveloped but potentially promising solutions to focused evolutionary population. As a general framework, any Pareto-based approaches can be adapted to the proposed framework. As a case study, four representative Pareto-based approaches are selected to instantiate the framework. Experimental results show that Pareto-based algorithms with a focused evolutionary population can be appropriate for many-objective optimization problems, and thus the proposed framework paves a new way to improve the performance of Pareto-based approaches for many-objective optimization problems.
The Price of Anarchy: Centralized versus Distributed Resource Allocation Trade-offs

Optimizing decision quality in large scale, distributed, resource allocation problems requires selecting the appropriate decision network architecture. Such resource allocation problems occur in distributed sensor networks, military air campaign planning, logistics networks, energy grids, etc. Optimal solutions require that demand, resource status, and allocation decisions are shared via messaging between geographically distributed, independent decision nodes. Jamming of wireless links, cyber attacks against the network, or infrastructure damage from natural disasters interfere with messaging and, thus, the quality of the allocation decisions. Our contribution described in the paper is a decentralized resource allocation architecture and algorithm that is robust to significant message loss and to uncertain demand arrival, and provides fine-grained, many-to-many combinatorial task allocation. Most importantly, it enables a conscious choice of the best level of decentralization under the expected degree of communications denial and quantifies the benefits of approximating status of peer nodes using proxy agents during temporary communications loss.
A Research on the Methods for Prediction of the Slope Stability of Open-pit Mine

In order to improve the slope stability of open-pit mine, this paper proposed four prediction methods BP (Back Propagation)Neural Network, Naive Bayes Classifier, Decision Tree and Support Vector Machine for predicting the classification of slope stability of open-pit mine.Firstly, the sample data of slope stability in open-pit mine are preprocessed, and the new sample data are obtained after data standardization, discretization and attribute reduction. Then, the corresponding prediction model is established by selecting different methods. All the four methods have been successfully applied to the prediction of 8 groups of samples to be tested. In order to determine the optimal method, the detailed accuracy and node error rate are compared to analyze the prediction results. The research shows that the BP neural network has high reliability and good practicability in the evaluation of the slope stability of open-pit mine. Keywords—slope stability, back propagation, naive bayes classifier, support vector machine, decision tree, prediction
STUDY ON THE TAXONOMIC STATUS OF SPECIES OF BRACHYMYSTAX IN HEILONGJIANG RIVER AND TUMEN RIVER SYSTEMS BASED ON MITOCHONDRIAL CONTROL REGION SEQUENCE

Phylogenetic analysis was carried out for the sharp-snouted lenok and the blunt-snouted lenok distributed in Heilongjiang River system and B.tumensis from Tumen River based on the partial sequence of mitochondrial control region.Moreover,the evidence for genetic research on taxonomic status and applicability of the names for 2 species of Brachymystax,and B.tumensis in Tumen River as a valid species were supplied.Our data supports two independent evolutionary lineages in phylogenetic tree of Brachymystax fishes for lenok populations in Heilongjiang River system,which corresponds with the two phenotypically recongnizable forms of sharp-snouted lenok and blunt-snouted lenok with two very distinct external morphological characters,the genetic distance between these two independent evolutionary lineages was 1.9% with variation much above a normal species'divergence,B.tumensis in Tumen River and sharp snouted lenok populations from Huma River,Wusuli River and Kuile River form a monophyletic group,which had a genetic distance 1.2% with sharp-snouted lenok,far below the divergence of 2.2% with blunt-snouted lenok.Together with morphological characters(its external morphology is more like sharp-snouted lenok),our results don't support B.tumensis in Tumen River as a independent species,we suggest that B.tumensis is a synonym of B.lenok,and our results even don't supported assigned blunt-snouted lenok is B.tumensis,and its effective scientific name still needs further research.Our molecular results support the taxonomic diversion of two genetic lineages of lenok,that's to say,there is 2 independent species of Brachymystax in Heilongjiang River,which is B.lenok(sharp-snouted lenok)and B.sp. (blunt-snouted lenok),and B.tumensis is a synonym of B.lenok.
Deep Neural Networks with Intersection over Union Loss for Binary Image Segmentation

In semantic segmentation tasks the Jaccard Index, or Intersection over Union (IoU), is often used as a measure of success. While this measure is more representative than per-pixel accuracy, state-of-the-art deep neural networks are still trained on accuracy by using Binary Cross Entropy loss. In this research, an alternative is used where deep neural networks are trained for a segmentation task of human faces by optimizing directly an approximation of IoU. When using this approximation, IoU becomes differentiable and can be used as a loss function. The comparison between IoU loss and Binary Cross Entropy loss is made by testing two deep neural network models on multiple datasets and data splits. The results show that training directly on IoU significantly increases performance for both models compared to training on conventional Binary Cross Entropy loss.
Rail Degradation Predication: Melbourne Tram System Case Study

Nowadays, tram as an accessible and convenient mode of public transport is implemented and used in different cities. Due to high frequency of accelerations and decelerations along their routes and sharing the route with other vehicles, the rate of degradation of tram tracks (light rail) is different from the degradation rate of train tracks (heavy rail). In this paper, track gauge deviation as an indicator of irregularities on the rail-wheel contact surface is used for developing the track degradation model. Data set used in this study includes the curve sections of Melbourne tram network and divided into repaired and unrepaired segments. For data analysis more than 13 km of curved tracks are examined. Annual tonnage, previous gauge deviation and track structural properties like track surface, rail support, rail profile and gauge deviation are considered as the influencing variables on the future gauge deviation. Two different models including a regression model and an Artificial Neural Networks (ANN) model have been developed for predicting tram track gauge deviation. According to the results, the performances of the regression models are not very different from the ANN models. The determination coefficients of the selected models are approximately 0.8 and higher.
Supportive interpersonal relationships: a key component to high-performance sport

Social health determinants, including human social connections, are critical to sustain health and well-being1 and are central to elite sporting performance. Athletes live in high-pressure environments, and supportive relationships with coaches, support staff and/or others are vital to both athletic performance and well-being. Our study of World, Olympic and Paralympic champions revealed that while interpersonal relationships are a key contributor to high performance, they are not easily prescribed.2 Quality relationships can induce positive physiological changes that improve adaption to stress and enhance performance.3 The ability of relationships to mitigate stressful experiences is highlighted by Coan et al who found that access to social resources altered physiological and neuronal responses to a threat or stress.3 This study, which used functional MRI scans to document neuronal responses of women confronted with the threat of electrical shock, found that high-quality relationships reduced threat-related brain activation. This is consistent with research that suggests quality relationships attenuate physiological responses such as cardiovascular arousal, cortisol and glucocorticoid levels, reduce threat-related brain activity and enhance general health and longevity.1 4 An athlete’s progression and transition from novice to expert is greatly influenced by their social environment including peer interaction and culture.5 Like the general population, athletes have innate needs when it comes to building relationships, and interpersonal relationships can shape developmental experiences and perspectives for either better or worse. The stress associated with the highs and lows of competition, negative chance events (ie, injury, illness and so on), and the typical demands of high-performance sport (travel, funding, juggling a dual-career,6 non-selection, self-perceived poor performance, losses, relegation and the impact of social media) can be alleviated by a strong social scaffold. In contrast, non-accidental violence and maltreatment in sport, which includes psychological (bullying, harassment and ostracism), sexual and physical violence, is more prevalent in elite athletes and …
Sound source localization with varying amount of visual information in virtual reality

To achieve accurate spatial auditory perception, subjects typically require personal head-related transfer functions (HRTFs) and the freedom for head movements. Loudspeaker-based virtual sound environments (VSEs) allow for realism without individualized measurements. To study audio-visual perception in realistic environments, the combination of head mounted displays (HMDs) and VSEs may be valuable. However, HMDs may affect the subjects’ HRTFs and thus influence sound localization performance. Furthermore, due to limitations of the visual reproduction of the HMD, audio-visual perception might be influenced. Here, a sound localization experiment was conducted both with and without an HMD and with a varying amount of visual information provided to the subjects. Furthermore, interaural time and level difference errors (ITDs and ILDs) as well as spectral perturbations induced by the HMD were analyzed and compared to the perceptual localization data. The results showed a reduction of the localization accuracy when the subjects were wearing an HMD and when they were blindfolded. The induced changes of ITDs and ILDs were found to account for these errors. When visual information was provided, the localization error induced by the HMD was negligible. Presenting visual information of hand-location, room dimensions, source locations and pointing feedback on the HMD revealed similar effects as previously shown in real environments.

Also staff response on non training but motivational techniques positively high in the areas of Free Medical Services 184; Free Transport 102; Transport Allowance 184; Christmas Bonus 184 and others 130.Fewer numbers ranging between 8 and 65 variously identified classroom assignment, discussion and conferences, committee assignment, film, TV and cinema, etc off-the-job training techniques. Conclusion: The study revealed among others, that on-the-job training techniques were commonly adopted and considered most effective too. It also showed that the company’s manpower development was not based on training alone but also on other non-training staff welfare schemes designed to motivate workers.
Self-Reported and Parent-Reported School Bullying in Adolescents with High Functioning Autism Spectrum Disorder: The Roles of Autistic Social Impairment, Attention-Deficit/Hyperactivity and Oppositional Defiant Disorder Symptoms

The aim of this study was to examine the prevalence of self-reported and parent-reported bullying victimization, perpetration, and victimization-perpetration and the associations of autistic social impairment and attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) symptoms with bullying involvement in adolescents with high functioning autism spectrum disorder (ASD). A total of 219 adolescents with high functioning ASD participated in this study. The associations of sociodemographic characteristics, parent-reported autistic social impairment, and parent-reported ADHD and ODD symptoms with self-reported and parent-reported bullying victimization, perpetration, and victimization-perpetration were examined using logistic regression analysis. The results found that the agreement between self-reported and parent-reported bullying involvement was low. Compared with bullying involvement experiences reported by adolescents themselves, parents reported higher rates of pure bullying victimization (23.7% vs. 17.8%) and victimization-perpetration (28.8% vs. 9.1%) but a lower rate of pure bullying perpetration (5.9% vs. 9.1%). Deficit in socio-communication increases the risk of being pure victims and victim-perpetrators. Parent-reported victim-perpetrators had more severe ODD symptoms than did parent-reported pure victims.
Incorporating Voluntary Medical Male Circumcision Into Traditional Circumcision Contexts: Experiences of a Local Consortium in Zimbabwe Collaborating With an Ethnic Group

The successful collaboration resulted in a male circumcision camp where 98% of the 672 boys and men ages 10 and up chose voluntary medical male circumcision (VMMC) while traditional practices were respected. Such collaborations may improve patient safety and increase VMMC uptake in sub-Saharan Africa. The successful collaboration resulted in a male circumcision camp where 98% of the 672 boys and men ages 10 and up chose voluntary medical male circumcision (VMMC) while traditional practices were respected. Such collaborations may improve patient safety and increase VMMC uptake in sub-Saharan Africa. ABSTRACT Employing voluntary medical male circumcision (VMMC) within traditional settings may increase patient safety and help scale up male circumcision efforts in sub-Saharan Africa. In Zimbabwe, the VaRemba are among the few ethnic groups that practice traditional male circumcision, often in suboptimal hygienic environments. ZAZIC, a local consortium, and the Zimbabwe Ministry of Health and Child Care (MoHCC) established a successful, culturally sensitive partnership with the VaRemba to provide safe, standardized male circumcision procedures and reduce adverse events (AEs) during traditional male circumcision initiation camps. The foundation for the VaRemba Camp Collaborative (VCC) was established over a 4-year period, between 2013 and 2017, with support from a wide group of stakeholders. Initially, ZAZIC supported VaRemba traditional male circumcisions by providing key commodities and transport to help ensure patient safety. Subsequently, 2 male VaRemba nurses were trained in VMMC according to national MoHCC guidelines to enable medical male circumcision within the camp. To increase awareness and uptake of VMMC at the upcoming August–September 2017 camp, ZAZIC then worked closely with a trained team of circumcised VaRemba men to create demand for VMMC. Non-VaRemba ZAZIC doctors were granted permission by VaRemba leaders to provide oversight of VMMC procedures and postoperative treatment for all moderate and severe AEs within the camp setting. Of 672 male camp residents ages 10 and older, 657 (98%) chose VMMC. Only 3 (0.5%) moderate infections occurred among VMMC clients; all were promptly treated and healed well. Although the successful collaboration required many years of investment to build trust with community leaders and members, it ultimately resulted in a successful model that paired traditional circumcision practices with modern VMMC, suggesting potential for replicability in other similar sub-Saharan African communities.
Addition of Docetaxel to Oral Fluoropyrimidine Improves Efficacy in Patients With Stage III Gastric Cancer: Interim Analysis of JACCRO GC-07, a Randomized Controlled Trial

PURPOSE S-1 is a standard postoperative adjuvant chemotherapy for patients with stage II or III gastric cancer in Asia. Neoadjuvant or perioperative strategies dominate in Western countries, and docetaxel has recently shown significant survival benefits when combined with other standard regimens in advanced cancer and perioperative settings. PATIENTS AND METHODS This randomized phase III study was designed to prove the superiority of postoperative S-1 plus docetaxel over S-1 alone for R0 resection of pathologic stage III gastric cancer. The sample size of 1,100 patients was necessary to detect a 7% increase in 3-year relapse-free survival as the primary end point (hazard ratio, 0.78; 2-sided α = .05; β = .2). RESULTS The second interim analysis was conducted when the number of events reached 216 among 915 enrolled patients (median follow-up, 12.5 months). Analysis demonstrated the superiority of S-1 plus docetaxel (66%) to S-1 (50%) for 3-year relapse-free survival (hazard ratio, 0.632; 99.99% CI, 0.400 to 0.998; stratified log-rank test, P < .001), and enrollment was terminated as recommended by the independent data and safety monitoring committee. Incidences of grade 3 or greater adverse events, particularly neutropenia and leukopenia, were higher in the S-1 plus docetaxel group, but all events were manageable. CONCLUSION Addition of docetaxel to S-1 is effective with few safety concerns in patients with stage III gastric cancer. The present findings may also be applicable in countries in which perioperative adjuvant chemotherapy or chemoradiation is not standard.
