We study the problem of computing a minimal subset of nodes of a given asynchronous Boolean network that need to be perturbed in a single-step to drive its dynamics from an initial state to a target steady state (or attractor), which we call the source-target control of Boolean networks. Due to the phenomenon of state-space explosion, a simple global approach that performs computations on the entire network, may not scale well for large networks. We believe that efficient algorithms for such networks must exploit the structure of the networks together with their dynamics. Taking this view, we derive a decomposition-based solution to the minimal source-target control problem which can be significantly faster than the existing approaches on large networks. We then show that the solution can be further optimised if we take into account appropriate information about the source state. We apply our solutions to both real-life biological networks and randomly generated networks, demonstrating the efficiency and efficacy of our approach. [less ▲]

Malware is one of the most popular cyber-attack methods in the digital world. According to the independent test company AV-TEST, 350,000 new malware samples are created every day. To analyze all samples by hand to discover whether they are malware does not scale, so antivirus companies automate the process e.g., using sand- boxes where samples can be run, observed, and classified. Malware authors are aware of this fact, and try to evade detection. In this paper we describe one of such evasion technique: unprecedented, we discovered it while analyzing a ransomware sample. Analyzed in a Cuckoo Sandbox, the sample was able to avoid triggering malware indicators, thus scoring significantly below the minimum severity level. Here, we discuss what strategy the sample follows to evade the analysis, proposing practical defense methods to nullify, in our turn, the sample’s furtive strategy. [less ▲]

This paper explores the relationship between rating scales and response style using experimental data from a sample of 1500 households of the Innovation Panel (2008) which is part of the Understanding Society database. Two random groups of individuals are being asked about their level of job satisfaction using a self-assessment questionnaire through two (7 and 11 points) rating options. By comparing the two groups, we explore the effects of the different rating scales on Extreme Response Style (ERS). The experimental design of the data enables us to show that both high and low Extreme Response Style (ERS) are correlated with personal and demographic characteristics. In addition, when comparing the shorter to a longer scale, we show that the survey design may generates tendency to choose responses at the extreme values of the distribution. [less ▲]

Parkinson’s disease (PD) exhibits systemic effects on human metabolism with emerging roles for the gut microbiome. Here, we integrated longitudinal metabolome data from 30 drug-naïve, de-novo PD patients and 30 matched controls with constraint-based modeling of gut microbial communities derived from an independent, drug-naïve PD cohort, and prospective data from a general population. Our key results are i) longitudinal trajectory of metabolites associated with the interconversion of methionine and cysteine via cystathionine differed between PD patients and controls, ii) dopaminergic medication showed strong lipidomic signatures, iii) taurine-conjugated bile acids correlated with the severity of motor symptoms, while low levels of sulfated taurolithocholate were associated with incident PD in the general population, and iv) computational modeling predicted changes in sulfur metabolism, driven by A. muciniphila and B. wadsworthia, consistent with the changed metabolome. In conclusion, the multi-omics integration revealed PD-specific patterns in microbial-host sulfur co-metabolism that may contribute to PD severity. [less ▲]

Runtime verification is an area of formal methods that studies the dynamic analysis of execution traces against formal specifications. Typically, the two main activities in runtime verification efforts are the process of creating monitors from specifications, and the algorithms for the evaluation of traces against the generated monitors. Other activities involve the instrumentation of the system to generate the trace and the communication between the system under analysis and the monitor. Most of the applications in runtime verification have been focused on the dynamic analysis of software, even though there are many more potential applications to other computational devices and target systems. In this paper we present a collection of challenges for runtime verification extracted from concrete application domains, focusing on the difficulties that must be overcome to tackle these specific challenges. The computational models that characterize these domains require to devise new techniques beyond the current state of the art in runtime verification. [less ▲]

Slender constituents are present in many structures and materials. In associated mechanical models, each slender constituent is often described with a beam. Contact between beams is essential to incorporate in mechanical models, but associated contact frameworks are only demonstrated to work for beams with circular cross-sections. Only two studies have shown the ability to treat contact between beams with elliptical cross-sections, but those frameworks are limited to point-wise contact, which narrows their applicability. This contribution presents initial results of a framework for shear-deformable beams with elliptical cross-sections if contact occurs along a line or at an area (instead of at a point). This is achieved by integrating a penalty potential over one of the beams’ surfaces. Simo-Reissner Geometrically Exact Beam (GEB) elements are employed to discretise each beam. As the surface of an assembly of such beam elements is discontinuous, a smoothed surface is introduced to formulate the contact kinematics. This enables the treatment of contact for large sliding displacements and substantial deformations. [less ▲]

Intergenerational value transmission occurs widely and to a large extent within the family as primary socialization agent. In families, children are confronted with specific practices, paradigms, rules and routines which are part of their family culture (Albert & Barros Coimbra, 2017) and as such family is a mediator between societal/cultural and individual values. The ability to transmit values is essential for collective knowledge and memory, the continuity of value orientations being a main feature of intergenerational relations that enables members of different generations to communicate with each other (Barni, Rosnati, & Ranieri, 2013; Halbwachs, 1941/1992; Schönpflug, 2001). Intergenerational transmission of values becomes particularly complex in the context of migration or in times of rapid social change. On the one hand, family identity and traditions might provide a secure base in light of a changing context, and parents might find it important to transmit traditional values to the next generation in order to keep memories alive. At the same time, they might feel that their children should adapt to the changed cultural context, resulting in a (not always clear) dilemma about what they want for their children. How can migrant parents reconcile or move between the different collective frameworks of their culture of origin and the receiving culture (Middleton & Brown, 2005)? In the following, we will first give a brief overview over research in the area of intergenerational value transmission, and we will second illustrate and further inform our theoretical assumptions by identifying related themes and phenomena in our qualitative dyadic interviews. Then, we will delve into memory as a horizon that is emerging out of the analysis as a transversal theme. From this point of view, we continue the analysis and progressively integrate the notions pertaining to the role of memory in the intergenerational transmission of values. Aspects of cultural background are apparent in the excerpts that we will quote supporting the themes we will refer to. We will more explicitly return to this in our conclusions. [less ▲]

Anxiety symptoms and anxiety disorders are highly prevalent among older adults, and are associ- ated with considerable distress, functional impairment, and burden. Also, there is growing need for brief instruments to measure anxiety symptoms in primary care and geriatric medical settings. Therefore, the current study focuses on the development and psychometric evaluation of a short- form of the Geriatric Anxiety Scale (GAS-G), a well-established anxiety instrument for use with older adults. Study 1 draws on the original data from the GAS-G validation study (N1⁄4242) to develop the short-form (GAS-G-SF) and determines whether the results replicate with the short- form. Study 2 extends the validation of the GAS-G-SF to a clinical sample (N1⁄4156; 62 patients with heart disease, 94 patients with Parkinson’s disease). Overall, the GAS-G-SF showed promising psychometric properties in terms of internal consistency and validity. Also, the GAS-G-SF showed good discriminatory power based on receiver operating characteristic curve analysis in both stud- ies. These results support the utility of the GAS-G-SF as a brief assessment measure for anxiety. [less ▲]
