Febrile seizures affect 2–4% of all children1 and have a strong genetic component2. Recurrent mutations in three main genes (SCN1A, SCN1B and GABRG2)3, 4, 5 have been identified that cause febrile seizures with or without epilepsy. Here we report the identification of mutations in STX1B, encoding syntaxin-1B6, that are associated with both febrile seizures and epilepsy. Whole-exome sequencing in independent large pedigrees7, 8 identified cosegregating STX1B mutations predicted to cause an early truncation or an in-frame insertion or deletion. Three additional nonsense or missense mutations and a de novo microdeletion encompassing STX1B were then identified in 449 familial or sporadic cases. Video and local field potential analyses of zebrafish larvae with antisense knockdown of stx1b showed seizure-like behavior and epileptiform discharges that were highly sensitive to increased temperature. Wild-type human syntaxin-1B but not a mutated protein rescued the effects of stx1b knockdown in zebrafish. Our results thus implicate STX1B and the presynaptic release machinery in fever-associated epilepsy syndromes. [less ▲]

Using exome sequencing, we identify SERAC1 mutations as the cause of MEGDEL syndrome, a recessive disorder of dystonia and deafness with Leigh-like syndrome, impaired oxidative phosphorylation and 3-methylglutaconic aciduria. We localized SERAC1 at the interface between the mitochondria and the endoplasmic reticulum in the mitochondria-associated membrane fraction that is essential for phospholipid exchange. A phospholipid analysis in patient fibroblasts showed elevated concentrations of phosphatidylglycerol-34:1 (where the species nomenclature denotes the number of carbon atoms in the two acyl chains:number of double bonds in the two acyl groups) and decreased concentrations of phosphatidylglycerol-36:1 species, resulting in an altered cardiolipin subspecies composition. We also detected low concentrations of bis(monoacyl-glycerol)-phosphate, leading to the accumulation of free cholesterol, as shown by abnormal filipin staining. Complementation of patient fibroblasts with wild-type human SERAC1 by lentiviral infection led to a decrease and partial normalization of the mean ratio of phosphatidylglycerol-34:1 to phosphatidylglycerol-36:1. Our data identify SERAC1 as a key player in the phosphatidylglycerol remodeling that is essential for both mitochondrial function and intracellular cholesterol trafficking. [less ▲]

Program based test adequacy criteria (TAC), such as statement, branch coverage and mutation give objectives for software testing. Many techniques and tools have been developed to improve each phase of the TAC-based software testing process. Nonetheless, The engineering effort required to integrate these tools and techniques into the software testing process limits their use and creates an overhead to the users. Especially for system testing with languages like C, where test cases are not always well structured in a framework. In response to these challenges, this paper presents Muteria, a TAC-based software testing framework. Muteria enables the integration of multiple software testing tools. Muteria abstracts each phase of the TAC-based software testing process to provide tool drivers interfaces for the implementation of tool drivers. Tool drivers enable Muteria to call the corresponding tools during the testing process. An initial set of drivers for KLEE, Shadow and SEMu test-generation tools, Gcov, and coverage.py code coverage tools, and Mart mutant generation tool for C and Python programming language were implemented with an average of 345 lines of Python code. Moreover, the user configuration file required to measure code coverage and mutation score on a sample C programs, using the Muteria framework, consists of less than 15 configuration variables. Users of the Muteria framework select, in a configuration file, the tools and TACs to measure. The Muteria framework uses the user configuration to run the testing process and report the outcome. Users interact with Muteria through its Application Programming Interface and Command Line Interface. Muteria can benefit to researchers as a laboratory to execute experiments, and to software practitioners. [less ▲]

A critical step in multi-frame super-resolution is the registration of frames based on their motion. We improve the performance of current state-of-the-art super-resolution techniques by proposing a more robust and accurate registration as early as in the initialization stage of the high resolution estimate. Indeed, we solve the limitations on scale and motion inherent to the classical Shift & Add approach by upsampling the low resolution frames up to the super-resolution factor prior to estimating motion or to median filtering. This is followed by an appropriate selective optimization, leading to an enhanced Shift & Add. Quantitative and qualitative evaluations have been conducted at two levels; the initial estimation and the final optimized super-resolution. Results show that the proposed algorithm outperforms existing state-of-art methods. [less ▲]

Ein Großteil der wissenschaftlichen Publikationen der letzten zwanzig Jahre zum Thema Mehrsprachigkeit in Luxemburg stellt Webers Konzept der Mischkultur zu Recht als Pfeiler von nationalen Kulturtheorien und Identitätsmodellen hin. Der vorliegende Beitrag möchte zu einer differenzierteren Betrachtung des Artikels von 1909 im Kontext von Webers Gesamtwerk anregen und anhand der Quelle der Feuilletonserie Abreißkalender (1913-1940) deutlich machen, dass für Weber die Mischkultur keine permanente Identität bedeutete, sondern einen andauernden Prozess des Negoziierens, der Zueigenmachung, der Ablehnung, der Assimilierung und der Emanzipation von interkulturellen Elementen. Weber tritt zwar in diesem Text für die Wertschätzung der luxemburgischen Kultur ein, stellt aber im Laufe seiner journalistischen und literarischen Laufbahn selbst sprachliche Qualitätsstandarde auf, die, durch interkulturellen Vergleich, die Bildung, Kompetenz und Ausdrucksfähigkeit seiner Leser in Frage stellen. Wenn auch Weber seinen Identitätsbegriff nie an klar definierten binären Dichotomien von fremd und eigen festmacht, so fordert er doch wiederholt die einwandfreie Beherrschung mehrerer Standardsprachen, indem er klar zwischen Fehler und korrektem Gebrauch unterscheidet. Während die Mischung von französischen, deutschen und luxemburgischen Kulturelementen für Weber den verallgemeinerten Luxemburger ausmacht, stellt er sprachliche Interferenzen als Fehler dar. Diese Fehlerhaftigkeit ist stark kontextabhängig: im Sprachgebrauch der Bevölkerung stellt Weber Vermischungen von Sprachsystemen oft als Zeichen von Inkompetenz und Anmaßung dar aber im Bereich der Kunst zeugen sie, ihm zufolge, von Kreativität, Individualität und luxemburgischer Eigenart. Besonders in den ersten Jahren seines Feuilletons, ca. 1913 bis 1920, beschäftigt sich Weber mir linguistischen Notionen der Korrektheit, die in den 1930er Jahren stark an Bedeutung verlieren. In diesem Jahrzehnt sind Feuilletons, in denen Weber versucht das Kunstpotential der Luxemburger Literaten genau zu lokalisieren, häufig. [less ▲]

It was recently shown by Barato et al (2013 Phys. Rev. E 87 042104) that the mutual information at the trajectory level of a bipartite Markovian system is not bounded by the entropy production. In the same way as Gaspard showed (2004 J. Stat. Phys. 117 599) that the entropy production is not directly related to the Shannon entropy at the trajectory level but is in fact equal to its difference from the so-called time-reversed Shannon entropy, we show in this paper that the difference between the mutual information and its time-reversed form is equal to the mutual entropy production (MEP), i.e. the difference between the full entropy production and that of the two marginal processes. Evaluation of the MEP is in general a difficult task due to non-Markovian effects. For bipartite systems, we provide closed expressions in various limiting regimes which we verify by numerical simulations. [less ▲]

We present evidence that some mutual funds systematically act as contrarian traders, and earn returns in the stock market by providing liquidity to investors that demand immediacy, while others systematically realize costs of immediacy. On average, the mutual funds’ costs of immediacy exceed their returns from providing liquidity. The funds with outflows, flows that correlate with industry flows, high market beta funds, and funds highly exposed to the momentum strategy suffer the most in costs of immediacy. The mutual funds’ average underperformance can be explained with their costs of immediacy. Finally, the funds’ historical costs of immediacy predict their alphas. [less ▲]

Pooling of member-states debts is not authorized by European treaties and would imply a handing over of budgetary responsibilities from member States to the Union. Restructuring these debts is practicable according to ordinary law (collective action clause) and backed by the European Stability Mechanism. There are also some alternative solutions which are more in keeping with the Union spirit: budgetary discipline, financial aid backed by the EIB, asset purchasing by the ECB which does not go without risks and has limits.
