[more ▼]We devise the first closed formula for the number of rounds of a blockcipher with secret components so that these components can be revealed using multiset, algebraic-degree, or division-integral properties, which in this case are equivalent. Using the new result, we attack 7 (out of 9) rounds of Kuznyechik, the recent Russian blockcipher standard, thus halving its security margin. With the same technique we attack 6 (out of 8) rounds of Khazad, the legacy 64-bit blockcipher. Finally, we show how to cryptanalyze and find a decomposition of generic SPN construction for which the inner-components are secret. All the attacks are the best to date.

[more ▼]Multistability is found to be an important recurring theme in synthesis biology. In this article, the multistability analysis problem is investigated by applying control theory and mathematical tools. Both the modelling and analysis issues are discussed. Specifically, the genetic regulatory networks (GRNs) with multistability are modelled as switched systems with interval time-varying delays and parameter uncertainties, where the piecewise-affine models are used to approximate the inherent non-linearities existing in the GRNs. Then, by using a novel Lyapunov functional approach and linear matrix inequality (LMI) techniques, a few delay-dependent criteria for the multistability of such genetic regulatory networks are established in the form of LMIs, which can be readily verified by using standard numerical software. A three-component network and a genetic toggle switch with bistability are employed to illustrate the applicability and usefulness of the developed theoretical results.

[more ▼]We present a detection scheme for attacks on a Cyber-Physical System (CPS) in which we leverage the connectivity of a multistage process to detect attacks downstream from the point of attack. Our methods form a control theoretic approach to CPS security by characterizing a real water treatment facility with a mathematical model; obtaining a residual (error) signal from sensor measurements and sensor measurement estimates; and finally using Cumulative Sum (CUSUM) and Bad-Data detection methods to detect the presence of a sensor attack. In particular, the attacks are designed so that they do not raise alarms on the detectors in the same stage where the attack takes place, requiring detection to take place on a separate part of the system. Proposed scheme is implemented on a real world water treatment facility. Extensive experiments are carried out and results show the significance of the proposed scheme.

[more ▼]This article introduces an efficient multithreading local search algorithm for solving the multiobjective scheduling problem in heterogeneous computing systems considering the makespan and energy consumption objectives. The proposed method follows a fully multiobjective approach using a Pareto-based dominance search executed in parallel. The experimental analysis demonstrates that the new multithreading algorithm outperforms a set of deterministic heuristics based on Min-Min. The new method is able to achieve significant improvements in both objectives in reduced execution times for a broad set of testbed instances.

[more ▼]We address the problem of combining limited feedback information with long-term channel statistical information in the design of downlink SDMA schemes. A novel combining method is developed to improve the quality of channel knowledge at the base station. More specifically, a set of novel feedback parameters is proposed and a related method is developed to estimate a representation of the multiuser channel vectors at the base station. This method utilizes the hybrid information by combining instantaneous channel feedback and long-term channel statistics, and is based on a channel phase codebook designed using the generalized Lloyd algorithm. The estimated channel knowledge at the base station can be used for joint design of multiuser precoding and opportunistic scheduling. The advantage of the proposed scheme over existing CSI quantization based SDMA schemes is further confirmed by computer simulations.

[more ▼]Our study is founded on a multivariate approach to creativity. We analyze cognitive and personality variables in relationship to creative potential. The sample consists of 37 middle aged adults from the Grand Duchy of Luxembourg (20 women, 17 men, MAge = 41.03, SD = 7.23, age range: 29-55 years). Whereas ego-strength is positively related to creative potential, it is negatively related to psychoticism. We argue that in a population of academics psychoticism is not an essential condition for creative potential. It is rather the other side of the same coin. Ego-strength is some kind of moderator variable that determines which feature will be uncovered. We conceive that this ensues in three different forms of creativity. The first one relies on mental strength and emotional stability; the second one on emotional vulnerability and finally the third one arises from a confluence of both features.

We demonstrate the usefulness of that expression in the computation of orness and andness average values of certain aggregation functions. By generalizing our result to Riemann-Stieltjes integrals, we also provide a method for the calculation of certain expected values and distribution functions.

[more ▼]We present a new approach on shape preserving estimation of probability distribution and density functions using wavelet methodology for multivariate dependent data. Our estimators preserve shape constraints such as monotonicity, positivity and integration to one, and allow for low spatial regularity of the underlying functions. As important application, we discuss conditional quantile estimation for financial time series data. We show that our methodology can be easily implemented with B-splines, and performs well in a finite sample situation, through Monte Carlo simulations.

[more ▼]A MULTIVERSE AXIOM INDUCTION FRAMEWORK The multiverse paradigm in set theory does not only reflect philosophical preferences, or set up a new playground for mathematical investigation, but it also offers a powerful methodological tool for investigating the conceptual foundations of set theory by guiding the search for and the evaluation of new set-theoretic axioms or facts. The prototypical example is Friedman's Hyperuniverse Program (HUP). Our goal is to develop an abstract inferential framework generalizing the HUP whose (defeasible, inductive) inference methods are meant to identify or validate new axioms. We consider nonmonotonic consequence relations |~, parametrized by specifications of the multiverse and set-theoretic desiderata, which associate with any suitable ZFC + X new - not necessarily classically derivable - candidate truths. The desiderata could, for instance, consist of consistency conditions or maximization demands w.r.t. preorders over universes. There are a number of possible inductive strategies, but it doesn't seem that conceptual considerations at the level of set theory are sufficient to decide among them. The idea is therefore to also assess the inferential level and to use rationality postulates for nonmonotonic inference, heavily investigated within AI for modeling commonsense reasoning, to classify and evaluate such procedures. This is however a non-trivial task because of the special characteristics of axiom induction.

[more ▼]In educational sciences, the gathering of video diaries as a form of "student standpoint research" has become increasingly important, and critical developments in educational ethnography support participatory frameworks of ethnographic research projects. Legitimizing research subjects' voices through their own data collection corresponds to ethical demands of democratic, dialogical, multivoiced research. In this chapter, we combine perspectives from two different research projects in primary schools in Luxembourg to shed light on the methodological and practical underpinnings of collectively gathered audio-visual ethnographic data. Drawing on video data collected by children in schools, we consider ways in which children’s documentation of their school experiences allows for dynamic approaches to space, context, time, reality and identity. As we analyze the coherence between this kind of multiperspectival data and the demands of ethnographic research we seek to demonstrate the extents to which such methods allow for an interpretation of institutionally embedded, highly performative and individualised data authored by the children themselves.
