In this paper, the influence of microscopic parameters on the macroscopic behaviour of polycrystalline materials under different loading configuration is investigated. Linear elastic grains with zero thickness cohesive interfaces are considered at the microscale with in depth introduction of effective parameters. A multiscale method based on homogenisation technique is employed to bridge the scales. In order to minimize the homogenisation error, a representative volume element (RVE) of the microscopic structure is statistically determined to be used in the numerical analysis. For each loading condition of the RVE, several numerical examinations are conducted to illustrate the relationship between the microscopic parameters. Finally, the effects of microscopic critical fracture energies, maximum tensile and shear strengths of grain interfaces on the mechanical properties, i.e. stress-strain curve and yield surface at the macroscale are discussed in details. It is shown that macroscopic yield surface and stress strain curves can be used to characterise the microscopic properties. [less ▲]

This thesis consists of two parts. Part I is an introduction to Hermite processes, Hermite random fields, Fisher information and to the papers constituting the thesis. More precisely, in Section 1 we introduce Hermite processes in a nutshell, as well as some of its basic properties. It is the necessary background for the articles [a] and [c]. In Section 2 we consider briefly the multiparameter Hermite random fields and we study some less elementary facts which are used in the article [b]. In section 3, we recall some terminology about Fisher information related to the article [d]. Finally, our articles [a] to [d] are summarised in Section 4. Part II consists of the articles themselves: [a] T.T. Diu Tran (2017): Non-central limit theorem for quadratic functionals of Hermite-driven long memory moving average processes. Stochastic and Dynamics, 18, no. 4. [b] T.T. Diu Tran (2016): Asymptotic behavior for quadratic variations of nonGaussian multiparameter Hermite random fields. Under revision for Probability and Mathematical Statistics. [c] I. Nourdin, T.T. Diu Tran (2017): Statistical inference for Vasicek-type model driven by Hermite processes. Submitted to Stochastic Process and their Applications. [d] T.T. Diu Tran (2017+): Fisher information and multivariate Fouth Moment Theorem. Main results have already been obtained.

Sir, In their letter in this issue, Gaare and colleagues (2018) state that TRAP1 may not be a Parkinson’s disease gene because of lack of genetic association. In response, we welcome their data analyses and we welcome any further genetic analyses of TRAP1 variants in additional Parkinson’s disease genetic datasets, including the reanalysis of open access datasets such as the Parkinson’s Progressive Markers Initiative (PPMI). Our point of view is that TRAP1 is an interesting effector protein that our study unequivocally showed is relevant to Parkinson’s disease signaling in the context of mitochondrial regulation. Furthermore, the overall contribution of TRAP1 genetic variants to Parkinson’s disease was not the focus of our recent paper in Brain (Fitzgerald et al., 2017). [less ▲]

Research suggests negative effects of unemployment and skill underutilization on subsequent labor market outcomes. Among others, signaling theory has been used to explain why recruiters may evaluate competence and commitment of some job applicants less favorably than others. However, various country-, firm-, occupation-, and job-specific context factors may moderate such scarring effects. For example, a high youth unemployment rate may be associated with more scarring of previous unemployment spells and these effects might be different for occupations with different skill requirements. In this contribution, we explore the moderating role of transaction costs, i.e., the direct and indirect costs of recruiting and training new employees for scarring due to previous unemployment and skill underutilization. Furthermore, we investigate the extent to which the perceived difficulty of recruiting moderates these effects. Using data from a recent large-scale factorial survey of recruiters in four European countries (N~=~2,000) and employing multilevel linear regression models, we found, overall, scarring due to skill underutilization to exceed scarring due to unemployment. Skill underutilization was especially penalized when recruiting for a particular position was considered easy. Indirect transaction costs, particularly anticipated time required for organizational socialization, were negatively associated with unemployment scarring, but positively with scarring due to skill underutilization. Unemployment spells only had a negative effect on hiring chances, for jobs where there were monetary expenses for introductory trainings. Our findings constitute new evidence on the heterogeneity of scarring effects on hiring chances. We further contribute to the literature by highlighting the role of transaction costs and labor market performance. [less ▲]

Rolandic Epilepsy (RE) is the most common focal epilepsy in childhood. To date no hypothesis-free exome-wide mutational screen has been conducted for RE and Atypical RE (ARE). Here we report on whole-exome sequencing of 194 unrelated patients with RE/ARE and 567 ethnically matched population controls. We identified an exome-wide significantly enriched burden for deleterious and loss-of-function variants only for the established RE/ARE gene GRIN2A. The statistical significance of the enrichment disappeared after removing ARE patients. For several disease-related gene-sets, an odds ratio > 1 was detected for loss-of-function variants. [less ▲]

Als 1917 die Revolution Frauen den Männern gleichstellt, ist die Sowjetunion das fortschrittlichste Land der Welt: Frauen dürfen wählen, studieren und in die Politik gehen. Allen voran Nadeschda Krupskaja, die Ehefrau und Kampfgefährtin von Revolutionsführer Lenin. Mit seinem Nachfolger Stalin jedoch verschwinden die Frauen im Kreml wieder von der Bildfläche. Der Diktator entmachtet Krupskaja, seine Ehefrau Nadeschda Allilujewa darf nicht mehr öffentlich auftreten. Sie vereinsamt und nimmt sich 1932 das Leben. Den anderen Kremlfrauen verordnet Stalin ein traditionelles Lebensmodell, das bis heute gilt. Während damals gewöhnliche Russinnen zur Arbeit gehen mussten, bleiben sie meist unfreiwillig zuhause. So ergeht es auch Nina Petrowna, der Lebensgefährtin von Nikita Chruschtschow, und der Ehefrau von Leonid Breschnew, Viktoria Breschnewa. Beide geben zugunsten der Karriere ihrer Männer den Beruf auf und ebnen damit ihren Männern den Weg an die Spitze des Staates. Dies ändert sich erst gegen Ende der Sowjetunion. Trotz politischer Umwälzungen wird auch von Raissa Gorbatschowa, der Ehefrau von Michail Gorbatschow erwartet, dass sie sich zurückhält und gehorcht. Doch sie lehnt sich auf und handelt eigenständig. Am Ende zerbricht die Frau des großen Reformers, Raissa Gorbatschowa, am starren Kremlapparat. Nur einer gelingt es, sich aus dem Bann der Macht zu befreien: Ljudmila Putina. [less ▲]

Computer-supported collaborative work is increasingly common in our professional and personal life. However, the expectations and requirements of the users are frequently neglected when addressing the technological challenges associated with the development of a distributed collaboration system. The proposed collaboration environment employs an integrative approach to distributed compound document authoring, including both a user- and system-centric perspective on collaborative work. An interruption-free, reliable, and responsive shared work environment with a near real-time representation of the work of others is a core expectation from the users. In order to provide these features, a fine-granular, graph-based data representation has been developed to serve as the basis for this approach. The data representing individual compound document elements is partitioned over sets of three distinct nodes in the graph structure. This separation of metadata and payload data enables the precise attribution of editing operations while maintaining an adaptable and extensible data representation. User-specific preferences allow for the individualization of a user's work environment to account for personal preferences, requirements from the current collaboration scenario, or limitations of the employed computer system. Support for complex, data type-specific editing commands is integrated with a concurrent command application and Layered Consistency Management model. This enables a near real-time representation of the work of others, the preservation of the users' editing intentions, and the maintenance of a globally consistent data state. Intra- and inter-document relations retain semantic connections between distinct data structure elements. Together with an element's supplemental data, this related information enables additional, autonomous conflict resolution approaches and facilitates a comprehensive representation of the conflict in case of a manual resolution process. By integrating these functionalities into one coherent system, the users are provided with an unobtrusive, yet reliable and feature-rich distributed work environment able to actively support collaborative compound document authoring.

The investigation and condition assessment of bridges have a very high priority in the construction industry today. Particularly, due to the fact that many bridge structures are getting old and partly reach the end of their useful life, the control and condition assessment of bridge structures have become very important and essential. The present research work introduces an efficient new method for condition assessment called the Deformation Area Difference (DAD) Method. This new method represents an attractive alternative to visual inspection and long-term monitoring. In this paper, the new method with its theoretical background is presented and explained by means of a laboratory experiment and some additional theoretical calculation examples. The experimental investigations have been realised on a reinforced concrete beam, which has been gradually loaded until failure. For each load step, the stiffness reduction and the apparent cracking have been monitored. High-precision measurements such as close-range photogrammetry, digital levelling and displacement sensors have been used for the determination of the deflection curve. The DAD method has been applied to identify the area of the crack pattern of the laboratory experiment. Furthermore, the method is discussed with regard to the load level and the precision of the deformation measurements. On the basis of the laboratory experiment, the applicability of the DAD method for damage detection could be proven. Furthermore, the sensitivity of the method with regard to the damage degree, the static system, the damage position and the impact of temperature variation were analysed. [less ▲]
