On Relations between Gluons and Gravitons

In this thesis we analyze several cases of mysterious connections between gauge and gravity theories, known as double copy relations. We focus on tree level scattering amplitudes in Einstein-(scalar-)-chromo-dynamics, i.e. scattering scenarios between gluons, massive fundamental quarks (scalars) and gravitons. In these scenarios we study the sub leading contribution to the adjacent collinear gluon limits in pure Yang-Mills amplitudes. Recently, S. Stieberger and T. Taylor have proposed a linear combination of amplitudes with a pair of collinear gluons to an Einstein-Yang-Mills amplitude. We present a proof of such relations using a novel representation of bosonic tree level amplitudes based on a localized integral on the Riemann sphere, called the Cachazo-He-Yuan formalism. Moreover, we give insight into an intriguing interplay between those relations and surprising gauge invariance violations of the sub-leading collinear gluon limit of Yang-Mills amplitudes. Next, we will focus on yet another set of relations between Yang-Mills amplitudes and Einstein-Yang-Mills amplitudes that were also proposed by S. Stieberger and T. Taylor. They directly relate single gluons to single gravitons. We show universality of such relations, i.e. their validity in the presence of massive fundamental quarks and scalars. For that purpose, we will use a Feynman diagrammatic approach which results in a novel color-to-kinematics rule, mapping gluons to gravitons in these scattering scenarios. Finally, we establish a novel double copy connection between classical effective actions of two massive classical worldlines which are colored and interacting in Yang-Mills theory and dilaton charged and interacting through dilaton-gravity. Doing so, we extend and improve existing work relating the same system of worldlines through a double copy at the level of perturbative solutions to the involved equations of motion for the gluon and graviton fields, as has been proposed by W. Goldberger and A. Ridgway.
Transition in Cigarette Smoking Stages and its Relation with Parenting Styles of Parents among Iranian High School Students: A Longitudinal Study

Background: Smoking is increasing among adolescents, and family is a factor influencing it. The present study aimed to examine the relationship between transition in smoking stages and parenting styles of parents of adolescents. Materials and Methods: This was a longitudinal study in which 3968 high school students in Tabriz, Iran, were examined from November 2017 to June 2018. Sampling was multi-stage, with proportional and random clusters. A questionnaire containing demographic information and potential confounders were filled in by students, and the Parenting Style Inventory was completed by parents only in the first stage. Moreover, students twice (in the beginning of the study and six months later) completed a valid algorithm of stages of cigarette smoking. Data were analyzed using univariate and multivariate logistic regression analysis. Results: After the six-month interval, 429 students (11.7%) with a 95% Confidence Interval (CI) (10.68 - 12.76) progressed through the stages of smoking. By controlling potential confounding variables, the father’s permissive parenting style compared to the authoritative style increases the odds of progress through the stages of smoking by almost five times (OR=5.06, 95% CI: 2.58 - 9.93), and the father’s authoritarian parenting style compared to the authoritative style increases the odds of progress through the stages of smoking by almost four times (OR=4.01, 95% CI: 2.17 - 7.40). Conclusion: Inefficient parenting styles are an important risk factor for progress through the stages of cigarette smoking in adolescents. Desirable relationships between parents and children as well as parents’ awareness of parenting styles may prevent smoking in adolescents.
Real-Time Inspection System for Ballast Railway Fasteners Based on Point Cloud Deep Learning

Rail fasteners are the most numerous components in railways and they should be inspected periodically. Manual inspection is currently a common solution, which is laborious and low-efficient. Some automatic inspection approaches are proposed. But for ballast railway fasteners inspection, debris, especially ballast along tracks may cover the fasteners, which is still a tricky problem. In this paper, a real-time inspection system for ballast railway fasteners based on point cloud deep learning is developed. Dense and precise point cloud of fastener is obtained from the structured light sensors in the system. The point cloud of fastener is segmented into different parts to avoid the interference of debris on fasteners. A ballast fastener point cloud semantic segmentation dataset is created based on automatic annotation method. Several deep learning point cloud segmentation models are tested in this dataset and PointNet++ is selected to be deployed in the real-time deep learning module of the system. Field tests on ballast railways show excellent accuracy and efficiency of this system.
Statistical and spatial variability of climate data in the Mareb-Gash river basin in Eritrea

Introduction. Global reanalysis products are extensively used for hydrologic applications in sparse data regions. The establishment of inputs for hydrologic modelling from such global reanalysis requires prior checking and analyses. Materials and methods. The present study attempts to utilize Climate Forecast System Reanalysis (CFSR) datasets for the Mereb-Gash river basin in Eritrea, to prepare the input data for forthcoming hydrological modelling studies. The activities include statistical analyses, computation of PET, and drought indices using different methods so as to understand basin characteristics through the use of geospatial and geostatistical tools. Results. The results of statistical analyses indicated that there was predominantly a significant monotonic trend in the majority of the data. Precipitation (P) and relative humidity tend to decrease, whereas temperature (T) and potential evapotranspiration (PET) tend to increase. Among the PET estimation methods, the Thornthwaite method gave inconsistent results as compared to Hargreaves and Penman-Monteith methods, the former being highly dependent on the elevation of the station. In most cases, it was found that Penman-Monteith produced the highest PET values. Conclusions. Besides, Standardized Precipitation and Evapotranspiration Index (SPEI) analyses in the basin indicate persistent dry conditions over the period 2000–2013 and predominantly humid conditions over the period 1979–2000. The study concluded that the presence of a significant trend in most of the climatic variables and persistent drought conditions in recent years were found to be congruent with global and regional climatic studies that are highly likely linked to human and climate influence on the environment.
Oral health related quality of life in patients with diabetes mellitus type 2 in the year 2012

BACKGROUND AND AIM : The aim of this study was investigation of oral and dental side effects of diabetes mellitus (DM) on oral health-related quality of life (OHQoL) in patients with DM type 2. METHODS : In this descriptive, analytic study 121 patients were participated by consecutive method based on the type of diabetes and the age. After the subjects received adequate explanations about the necessity of carrying out such a study, a questionnaire was handed into each patient who gave their consent to take part in the study. Oral lesions consisted of ulcers, erythema, leukoplakia, erythroplakia, candidiasis, angular cheilitis, median rhomboid glossitis, and denture stomatitis based on oral examination. The OHQoL were surveyed by oral health impact profile (OHIP-14) questionnaire. Data were analyzed by Pearson’s correlation test, T-test, and χ 2 by SPSS software. RESULTS : A total of 121 patients with diabetes were evaluated in this study [31 males (25.6%) and 90 females (74.4%)]. In this study, there was no significant correlation between OHQoL and decayed, missing, and filled teeth, periodontal disease index. OHQoL was associated with higher ages and higher levels of blood sugar (P = 0.002, P = 0.016). The average of OHIP score significantly was increased by xerostomia experience (P = 0.010). CONCLUSION: In this survey, the influence of oral manifestation on OHQoL was low. Xerostomia was the most important symptom in diabetic patients that causes decreasing OHQoL. Age and blood sugar had more influence on this matter as well.

Spatial Characteristics of Flooded Areas in the Mun and Chi River Basins in Northeastern Thailand

The objectives of this study are to conduct an analysis on rainfall change tendencies, calculate the inundation in the basins of Mun and Chi Rivers in the northeastern region of Thailand, and clarify the flood risk in the long term, taking the spatial characteristics of flooding into consideration. To grasp the rainfall change tendencies, two statistical analyses are conducted using the Mann-Kendall test and the generalized extreme value distribution. The inundation analysis is conducted using the Rainfall-Runoff-Inundation (RRI) model. As a result of the statistical analysis on the rainfall characteristics, it can be observed that the annual rainfall has significant increasing tendencies at the significance level of 5% in a wide area of the upper reaches. In addition, inundation calculation indicates that the maximum inundation depth and inundation area have increased in recent years.
Factors Associated with Occupational Injuries of Ship-building Supply Workers in Busan.

Objective: This study was conducted to evaluate both personal and work-related factors associated with occupational injuries of ship-building supply workers in Busan, Korea. Methods: A self-administered, questionnaire survey, asking both personal and work-related factors associated with occupational injuries, was administered to 1,651 workers from 64 different ship-building supply companies in Busan, Korea. All occupational injuries had occurred within the previous 5 years. The workers were divided into three sub-groups: Group I, under 4 day-sick leave, Group II, 4 day-sick leave and over, and Group III, which consisted of both Groups I and II. The statistical significance of the factors associated with occupational injuries underwent cross tabulation analysis for each group. Afterwards, the relationships between the factors which had statistical significance and the occurrence of occupational injuries were analyzed through multiple logistic regression by using the SPSS 12.0 K program. Results: The prevalence of occupational injuries was 4.30% in Group II and 7.57% in Group III. The work activities which had the most frequent occupational injuries were ‘Fit-up’ and ‘Welding’, and 30.0% of injured workers were covered by workers’ compensation in Group II. According to the multiple logistic regression analysis results, the factors which had statistical significance in occupational injury occurrence were education level above college (OR 2.78) and high level of fatigue (OR 2.18) in Group I, sleeping less than 5 hours per day (OR 3.47), high level of fatigue (OR 2.79) and working over 56 hours per week (OR 1.53) in Group II, and education level above college (OR 1.78), sleeping less than 5 hours per day (OR 2.98), poor sleep quality (OR 1.65) and high level of fatigue (OR 2.58) in Group III. Conclusion: This study demonstrated that several factors of ship-building supply workers such as sleep hours, sleep quality, fatigue, working hours, and educational level exerted a statistical effect on the occurrence of occupational injuries. In association with occupational injuries occurrence, these factors need to be controlled by proper methods such as effective safety education, work condition modification, and life style management.
Compare and contrast Lifestyle Redesign and Traditional Chinese Medicine Regimen

ABSTRACT Randomised controlled trials beginning in the 1990s showing that the Lifestyle Redesign programme can improve the health-related quality of life and satisfaction. Traditional Chinese Medicine Regimen, which is the concept of ‘prevention is better than treatment’ clarifies methods of health preservation. We observed similarities between Traditional Chinese Medicine Regimen and Lifestyle Redesign despite their different cultural backgrounds. The pattern of self-care, stress management, time management, social network, environmental modification, productive activity, and entertainment were reviewed intend to increase interest on the application of Lifestyle Redesign and Traditional Chinese Medicine Regimen in occupational therapy. We elaborate the native concept of occupational therapy in Traditional Chinese Medicine Regimen, as well as the relationship between the International Classification of Functioning, Disability, and Health, connections between with Lifestyle Redesign, and discussed whether they can be conjunctively applied in occupational therapy. Future studies should investigate the feasibility of the actual joint incorporation of Lifestyle Redesign and Traditional Chinese Medicine Regimen into occupational therapy.
Features of optimization synthesis of equipment for feeding nanodispersed materials

For the first time, in the analysis of the behavior of a nanodispersed material (i.e., its outflow and batching from the hopper unit, as well as movement and mixing), a conventional approach was used to calculate the hardware and technological design of its functionalization. Besides, the features of the behavior of the nanodispersed layer and single nanoparticles as applied to the feeding process from the hopper under vibrations, its movement along the guide blade and the pouring of the flow into the receiving tank were considered, dependencies were formulated, and recommendations were given for designing the hopper assembly used to process the nanodispersed materials. The results were tested and showed high convergence in practical implementation.
Older Travelers’ E-Loyalty: The Roles of Service Convenience and Social Presence in Travel Websites

The research aims to examine what service convenience factors drive customer satisfaction in travel websites from the perspective of older travelers, and if older travelers’ satisfaction enhances e-loyalty. Additionally, drawing on socioemotional selectivity theory, this study argues that the social presence in travel websites plays a significant moderating role in increasing older travelers’ satisfaction. To empirically verify the conceptual model, an online survey was conducted targeting older travelers aged over 50 in the USA who have purchased products via travel websites. The data from 308 older travelers were analyzed, and the results revealed four dimensions of service convenience positively influence satisfaction. Unexpectedly, access convenience and transaction convenience do not influence older travelers’ satisfaction. The older travelers’ satisfaction with travel websites has a positive impact on e-loyalty. Additionally, social presence amplifies the effect of post-purchase convenience on satisfaction. The current research makes a significant contribution to understanding older travelers’ perceptions and behaviors for using e-commerce service in the field of tourism and provides practitioners with effective ways to attract older travelers for sustainable management of travel websites.
Practise on plastic: the impact of high fidelity simulation on learning and teaching

The integration of high fidelity simulation (HFS) as an adjunct resource into healthcare curricula is not a new phenomenon. Healthcare assistants (HCAs) are increasingly likely to be expected either to partake in high fidelity simulation training, or to work in the context of a multidisciplinary team (MDT) where this is commonplace activity in training or continuing professional development. HFS is regularly used in the context of medical, nursing and the allied healthcare professions to provide realistic scenarios where students can practise their clinical skills and interventions in an ethos of support and constructive feedback. Over the past five years particularly, the use of simulated practice as a teaching and learning tool within healthcare has increased in importance; it is seen as the major teaching method for practising and assessing developing skills, knowledge, attitudes and meaningful decision-making within the field of healthcare (Humphreys, 2013). The use of HFS offers a safe, non-threateni.

Dewey and Chinese Education: A Centennial Reflection

The year 2019 marks the 100th anniversary of Dewey’s two-year stay in China from 1919 to 1921. It is my honor to serve as the guest editor of this special issue on “Dewey and Chinese Education: A Centennial Reflection,” supported by Professor Michael A. Peters and Professor Zhu Xudong, the editors-in-chief of Beijing International Review of Education. It has been a few years since my book titled John Dewey, Liang Shuming and China’s Education Reform: Cultivate Individuality (Zhang, 2013) was published. Since that time, I have witnessed a steady spate of publications relating to Deweyan studies on China, written by both Chinese and international scholars in the fields of education and other disciplines, primarily philosophy. However, in light of a consideration of the turbulent history of such scholarship in China over the last 100 years, the recent burgeoning of Deweyan studies in China and on China should not be taken for granted. Instead, it should be viewed in the context of China’s developmental trajectory that has entailed highly complex social and political conditions. The contributors to this special issue engage with Dewey’s writings from the following key perspectives. The first entails the recognition that Dewey’s writings should be read from a comparative and cultural perspective to address practical problems in the field of Chinese education. Specifically, Dewey’s emphasis on the intellectual, ethical, and aesthetic experiences of the individual resonates with the concept of self-cultivation in traditional Confucianism. The commonalities between these two schools of thought are also indicative of a possible vision for a new humanism in the contemporary world, where clashes and violence are prevalent. Second, we hold that to illuminate Dewey’s legacy for Chinese education in the global context, it is necessary to consider his philosophy as a whole as opposed to extracting the part focusing on education from the wider body of his pragmatic thought. This exercise requires in-depth dialogue among scholars from different disciplines as well as from different
Systems Support for Emerging Memory Technologies

Trust and scalability are the two significant factors which impede the dissemination of clouds. The possibility of privileged access to customer data by a cloud provider limits the usage of clouds for processing security-sensitive data. Low latency cloud services rely on in-memory computations, and thus, are limited by several characteristics of Dynamic RAM (DRAM) such as capacity, density, energy consumption, for example. Two technological areas address these factors. Mainstream server platforms, such as Intel Software Guard eXtensions (SGX) und AMD Secure Encrypted Virtualisation (SEV) offer extensions for trusted execution in untrusted environments. Various technologies of Non-Volatile RAM (NV-RAM) have better capacity and density compared to DRAM and thus can be considered as DRAM alternatives in the future. However, these technologies and extensions require new programming approaches and system support since they add features to the system architecture: new system components (Intel SGX) and data persistence (NV-RAM). This thesis is devoted to the programming and architectural aspects of persistent and trusted systems. For trusted systems, an in-depth analysis of new architectural extensions was performed. A novel framework named EActors and a database engine named STANlite were developed to effectively use the capabilities of trusted~execution. For persistent systems, an in-depth analysis of prospective memory technologies, their features and the possible impact on system architecture was performed. A new persistence model, called the hypervisor-based model of persistence, was developed and evaluated by the NV-Hypervisor. This offers transparent persistence for legacy and proprietary software, and supports virtualisation of persistent memory.
sports d'hiver chez l'enfant ou l'adolescent

Contexte : Les sports d’hiver avec 8 millions de pratiquants chaque annee, suscitent un engouement incontestable en France. Ces sports sont pourvoyeurs de blessures dont des Traumatismes Crâniens (TC) parfois a risque eleve. Ils constituent un enjeu en termes de sante publique. Objectif : L’objectif principal de cette etude est d’identifier les facteurs aggravants et protecteurs des TC a risque eleve. Methodes : Les « cas » ont ete recueillis dans la base de donnees de Pediatrie du CHU de Grenoble. Les « temoins » sont issus de la base de donnees issues du comptage au pied des pistes ou des fiches « blesses » de Medecins de Montagne. La comparaison statistique entre ces populations s’est faite par des tests de Chi­deux et d’odds-ratio. Resultats : 43 enfants ou adolescents ont ete hospitalises pour TC a risque eleve suite a un accident de sport d’hiver sur ces 9 annees au CHU de Grenoble. Le casque apparait etre un facteur protecteur indeniable, il diminue le risque de TC a risque eleve de 3.45 fois. Les collisions entre usagers et contre un obstacle augmentent respectivement de 3.5 fois et de 27 fois le risque que le TC soit a haut risque par rapport a un TC benin. La luge parait etre egalement un sport a risque mais aucun test statistique n’a pu etre realise. Conclusion : Le casque protege des TC a haut risque alors que les collisions et la luge en sont des facteurs aggravants. Des campagnes de sensibilisation ont ete menees et ont porte leurs fruits mais il reste des ameliorations a apporter au niveau de l’amenagement des pistes, de la prevention et de l’education.
