Following the terrorist attacks in Paris (November 2015) and Brussels (March 2016), several EU Member States have decided to re-establish border controls or to build walls inside the Schengen Area. Although these decisions are temporary and legally framed by the Schengen code, their extent disrupts the free movement within the Schengen Area, in particular in border areas. While lawyers and economists have analyzed the impacts of this situation, the spatial perspective has remained rather neglected. This exploratory contribution aims to address this gap in the literature by outlining the spatial significance of reintroduced controls for border areas inside the Schengen Area. This contribution firstly undertakes a literature review of the different conceptual tools at hand. These are then compared with a set of exploratory empirical materials. The article focuses more precisely on the Greater Region where France and Germany have reintroduced border controls, thus disrupting in particular daily cross-border flows with Luxembourg and Belgium. The analysis demonstrates that the border acts as a filter, disrupting cross-border flows and cooperation. Also, it sheds some light on the important role played by the ideational perception of the border for practitioners and decision-makers. This contribution concludes by suggesting several paths for a future research agenda. [less ▲]

Dry-stacked masonry walls gives rise to geometric imperfections: the height variation of different masonry blocks ΔH and the roughness of the support area Δh. This paper studies the effect of ΔH on the structural response and the load bearing capacity of masonry walls by highlighting the load percolation. Furthermore, an algorithm was developed to define a stress multiplier coefficient respecting the imperfections ΔH. The algorithm allowed predicting 77% of the amplified stress compared to the FE analysis and showed that the geometric imperfections govern the load percolation in a wall as well as the cracking mode and the bearing capacity.

The Research Center for Autonomous Road Vehicles (RECAR) was founded in 2015 upon the initiative of the Faculty of Transportation Engineering and Vehicle Engineering of Budapest University of Technology and Economics. The research center is supported by industrial partners and other academic partners targeting research and educational purposes. In complement to this project, the construction of a new automotive test track is also under development especially for autonomous road vehicle testing serving as automotive proving ground in Zalaegerszeg, Hungary. Accordingly, an intensive research has been started in RECAR center in the field of autonomous vehicle technology. The paper’s goal is to share the main practical and methodological experiences with the scientific audience as well as the industrial sector. Based on the initial research actions we intend to enlighten the upcoming research challenges of driverless vehicles and automated intelligent transport system. Basically, three main topics are concerned. Firstly, the main issues concerning autonomous vehicle research are summarized. Secondly, the requirements for autonomous test track design are concluded. Thirdly, the legal questions that emerge with the appearance of driverless vehicles are investigated, especially concerning liability. [less ▲]

Data is a modern form of wealth in the digital world, and massive amounts of data circulate in cloud environments. While this enormously facilitates the sharing of information, both for personal and professional purposes, it also introduces some critical problems concerning the ownership of the information. Data is an intangible good that is stored in large data warehouses, where the hardware architectures and software programs running the cloud services coexist with the data of many users. This context calls for a twofold protection: on one side, the cloud is made up of hardware and software that constitute the business assets of the service provider (property of the cloud); on the other side, there is a definite need to ensure that users retain control over their data (property in the cloud). The law grants protection to both sides under several perspectives, but the result is a complex mix of interwoven regimes, further complicated by the intrinsically international nature of cloud computing that clashes with the typical diversity of national laws. As the business model based on cloud computing grows, public bodies, and in particular the European Union, are striving to find solutions to properly regulate the future economy, either by introducing new laws, or by finding the best ways to apply existing principles.

System testing plays a crucial role in safety-critical domains, e.g., automotive, where system test cases are used to demonstrate the compliance of software with its functional and safety requirements. Unfortunately, since requirements are typically written in natural language, significant engineering effort is required to derive test cases from requirements. In such a context, automated support for generating system test cases from requirements specifications written in natural language would be highly beneficial. Unfortunately, existing approaches have limited applicability. For example, some of them require that software engineers provide formal specifications that capture some of the software behavior described using natural language. The effort needed to define such specifications is usually a significant deterrent for software developers. This paper proposes an approach, OCLgen, which largely automates the generation of the additional formal specifications required by an existing test generation approach named UMTG. More specifically, OCLgen relies on semantic analysis techniques to automatically derive the pre- and post-conditions of the activities described in use case specifications. The generated conditions are used by UMTG to identify the test inputs that cover all the use case scenarios described in use case specifications. In practice, the proposed approach enables the automated generation of test cases from use case specifications while avoiding most of the additional modeling effort required by UMTG. Results from an industrial case study show that the approach can automatically and correctly generate more than 75% of the pre- and post-conditions characterizing the activities described in use case specifications.

EU’s response to the recent Euro-crisis has involved a mixture of EU and international law, with the latter being linked to all the arrangements that may have fiscal implications for national Member States. The SRF embodies all the controversial characteristics of Banking Union. This article illustrates the legal implications that this political choice creates, and how the interrelation between the SRM, the SRF and the ESM, allows leading economies, including Germany, to control the resolution framework both before and after crisis. This raises questions as to the direction that European Integration is taking and its highly nationalised character. [less ▲]

Most lung cancer deaths are related to metastases, which indicates the necessity of detecting and inhibiting tumor cell dissemination. Here, we aimed to identify microRNAs (miRNAs) involved in metastasis of lung adenocarcinoma as prognostic biomarkers and therapeutic targets. To that end, lymph node metastasis-associated miRNAs were identified in The Cancer Genome Atlas (TCGA) lung adenocarcinoma patient cohort (sequencing data; n=449) and subsequently validated by RT-qPCR in an independent clinical cohort (n=108). Overexpression of miRNAs located on chromosome 14q32 were associated with metastasis in lung adenocarcinoma patients. Importantly, Kaplan-Meier analysis and log-rank test revealed that higher expression levels of individual 14q32 miRNAs (mir-539, mir-323b, and mir-487a) associated with worse disease-free survival of never-smoker patients. Epigenetic analysis including DNA methylation microarray data and bisulfite sequencing validation demonstrated that the induction of 14q32 cluster correlated with genomic hypomethylation of the 14q32 locus. CRISPR activation technology, applied for the first time to functionally study the increase of clustered miRNA levels in a coordinated manner, showed that simultaneous overexpression of 14q32 miRNAs promoted tumor cell migratory and invasive properties. Analysis of individual miRNAs by mimic transfection further illustrated that miR-323b-3p, miR-487a-3p, and miR-539-5p significantly contributed to the invasive phenotype through the indirect regulation of different target genes. In conclusion, overexpression of 14q32 miRNAs, associated with the respective genomic hypomethylation, promotes metastasis and correlates with poor patient prognosis in lung adenocarcinoma. IMPLICATIONS: This study points to chromosome 14q32 miRNAs as promising targets to inhibit tumor cell dissemination and to predict patient prognosis in lung adenocarcinoma. [less ▲]

Internet-enabled smartphones are increasingly ubiquitous in the Western world. Research suggests a number of problems can result from mobile phone overuse, including dependence, dangerous and prohibited use. For over a decade, this has been measured by the Problematic Mobile Phone Use Questionnaire (PMPU-Q). Given the rapid developments in mobile technologies, changes of use patterns and possible problematic and addictive use, the aim of the present study was to investigate and validate an updated contemporary version of the PMPU-Q (PMPU-Q-R). A mixed methods convergent design was employed, including a psychometric survey (N = 512) alongside qualitative focus groups (N = 21), to elicit experiences and perceptions of problematic smartphone use. The results suggest the PMPU-Q-R factor structure can be updated to include smartphone dependence, dangerous driving, and antisocial smartphone use factors. Theories of problematic mobile phone use require consideration of the ubiquity and indispensability of smartphones in the present day and age, particularly regarding use whilst driving and in social interactions [less ▲]

OBJECTIVE: To assess the consequences of aneurysmal subarachnoid hemorrhage (aSAH) on sexual pleasure in patients with an otherwise favorable neurologic outcome. METHODS: Anonymous, standardized questionnaires concerning sexual function, including the International Index of Erectile Function (IIEF), Female Sexual Function Index (FSFI), and a statement on subjective change in sexual pleasure after aSAH, were completed by 33 patients treated at the Cantonal Hospital St Gallen between 2005 and 2013. All had favorable neurologic outcomes (Glasgow Outcome Scale score 4 or 5). RESULTS: Ten patients (31.3%) reported a subjective worsening of sexual pleasure after aSAH. Sexual dysfunction according to FSFI criteria affected 9 of the 19 female patients (47.4%). All 19 women had a hypoactive sexual desire disorder. Erectile dysfunction was present in 7 of the 14 male patients (50%). Patients with World Federation of Neurosurgical Societies (WFNS) grade 2 aSAH were significantly more likely to report a subjective worsening of sexual experience after hemorrhage than those with WFNS grade 1. CONCLUSIONS: This is the first known evaluation of sexual health following aSAH with otherwise favorable neurological outcomes, and confirms that sexual dysfunction is common in this population. Sexual health should be explored during follow-up with these patients [less ▲]
