Mutationen von Transkriptionsfaktoren (TF) betreffen nicht nur die Funktion des TFs, sondern auch die Expression seiner Zielgene und liegen häufig angeborenen Entwicklungsdefekten zugrunde. Über 20 Mutationen in HOXD13, einem TF der die Entwicklung der Extremitäten kontrolliert, sind bisher als Ursache verschiedenartiger Extremitätenfehlbildungen entdeckt worden. Eine molekularbiologische Grundlage für die Vielgestaltigkeit der HOXD13-Mutationen ist jedoch unbekannt. Die bisherigen Methoden zur funktionellen Charakterisierung von TF-Mutationen ermöglichten eine lediglich eingeschränkte Inte

Abstract:

Software is all around us in our lives in the industrialized world, and we as a society and individuals need it to function correctly. Software testing fills the role of performing behavior audits, to guide the correction of the software to its intended behavior. The consequences of faulty software can range to the late arrival of trains, to nuclear meltdowns. This places quality requirements on the software of various levels. Program based mutation testing provides a high level of faultfinding capability. It does this by injecting many synthetic faults into the code under test, as described b

Abstract:

The recessive hair loss mutant, dep, contains a mutation (del-233F) at the C-terminal of Zdhhc21. Wild-type Zdhhc21 has been shown to enhance palmitoylation of several specific substrates in a transfected cell assay. Zdhhc21 localises to the cis-Golgi, whereas the mutant protein is mislocalised and is inactive in palmitoylation. We verified the candidacy of Zdhhc21 by transgenic BAC rescue. Dep is characterised by progressive hair loss, hyperplasia of the sebaceous glands, the interfollicular epidermis and the outer root sheath.

Base rivalry arises at replication of monotonous DNA – sequences. Irreparable mutations can arise by tunnel processes if the developed energy is high enough. The tunnel probability depends not only on the base rivalry energy but also depends on the temperature of surroundings. The tunnel probability diminishes with decreasing temperature. The cytoplasm viscosity increases in the long term with decreasing temperature. The length of the monotonous sequence in which happens an irreparable mutation (caused by base rivalry) then will be larger than at higher temperatures. This means that the possib

Abstract:

Mutation Testing (or Mutation Analysis) is a source code testing technique which analyses code by altering code components. The output from the altered code is compared with output from the original code. If they are identical then Mutation Testing has been successful in discerning a weakness in either the test code or the test data. A mutation test therefore helps the tester to develop a program devoid of simple faults with a well developed test data set. The confidence in both program and data set is then increased. Mutation Analysis is resource intensive. It requires program copies, with on

Abstract:

Mutation testing is a fault-based software testing technique that has been studied widely for over three decades. To date, work in this field has focused largely on first order mutants because it is believed that higher order mutation testing is too computationally expensive to be practical. This thesis argues that some higher order mutants are potentially better able to simulate real world faults and to reveal insights into programming bugs than the restricted class of first order mutants. This thesis proposes a higher order mutation testing paradigm which combines valuable higher order mutan

Inspired by Happel's question, whether the exchange graph and the simplicial complex of tilting modules over a quiver algebra are independent from the multiplicities of multiple arrows in the quiver, we study quantitative aspects of Fomin and Zelevinsky's quiver mutation rule. Our results turn out to be very useful in the mutation-infinite case for understanding combinatorial structures as the cluster exchange graph or the simplicial complex of tilting modules, which are governed by quiver mutation. Using a class of quivers we call forks we can show that any such quiver yields a tree in the ex

Abstract:

Although much progress has been made in engineering multi-agent systems (MAS), many issues remain to be resolved. One issue is that there is a lack of techniques that can adequately evaluate the effectiveness (fault detection ability) of tests or testing techniques for MAS. Another is that there are no systematic approaches to evaluating the impact of possible semantic changes (changes in the interpretation of agent programs) on agents' behaviour and performance. This thesis introduces syntactic and semantic mutation to address these two issues. Syntactic mutation is a technique that systemati

Abstract:

Evolutionary algorithms (EAs) are a class of stochastic search and optimization algorithms that are inspired by principles of natural and biological evolution. Although EAs have been found to be extremely useful in finding solutions to practically intractable problems, they suffer from issues like premature convergence, getting stuck to local optima, and poor stability. Recently, researchers have been considering adaptive EAs to address the aforementioned problems. The core of adaptive EAs is to automatically adjust genetic operators and relevant parameters in order to speed up the convergence

Genetic Improvement (GI) of software is a recent field that has drawn much attention from Software Engineering researchers. It aims to use search techniques to automatically modify and improve existing software. The drawback in previous GI approaches is scalability of these approaches, due to the large search space formed by the code base in real-world systems. To overcome the scalability challenge, more recent studies have confined the granularity of code modification at the statement level and applied a prior sensitivity analysis to further reduce the search space.

The increasing use of dynamically typed programming languages brings a new challenge to software testing. In these languages, types are not checked at compile-time. Type errors must be found by testing and in general, programs written in these languages require additional testing compared to statically typed languages. Mutation analysis (or mutation testing) has been shown to be effective in testing statically (or strongly) typed programs. In statically typed programs, the type information is essential to ensure only type-correct mutants are generated. Mutation analysis has not so far been ful

Failure to do so may lead to critical faults, which may cause data loss or degradation of data quality, remaining undetected until later when they will prove much more costly to fix.

Research on the acquisition of grammatical gender has shown that for many languages, children gain an early command of gender. However, often in these languages gender marking is quite overt and provides a clear one-to-one correspondence between a marker and the gender encoded. In Welsh, gender marking is more complex. Gender is marked by mutations, a set of morphophonological changes that affect the initial consonants of words, and the mapping between mutation and gender is quite opaque.
