ATOM (Analysis Tools with OM) is a single framework for building a wide range of customized program analysis tools. It provides the common infrastructure present in all code-instrumenting tools; this is the difficult and time-consuming part. The user simply defines the tool-specific details in instrumentation and analysis routines. Building a basic block(More)
Code instrumentation is a powerful mechanism for understanding program behavior. Unfortunately, code instrumentation is extremely difficult, and therefore has been mostly relegated to building special purpose tools for use on standard industry benchmark suites. ATOM (Analysis Tools with OM) provides a very flexible and efficient code instrumentation(More)
Identifying variables as invariant or constant at compile-time allows the compiler to perform optimizations including constant folding, code specialization, and partial evaluation. Some variables, which cannot be labeled as constants, may exhibit semi-invariant behavior. A "semi-invariant" variable is one that cannot be identified as a constant at(More)
Variables and instructions that have invariant or predictable values at run-time, but cannot be identified as such using compiler analysis, can benefit from value-based compiler optimizations. Value-based optimizations include all optimizations based on a predictable value or range of values for a variable or instruction at run-time. These include constant(More)

BACKGROUND As degradation of formalin-fixed paraffin-embedded (FFPE) samples limits the ability to profile mRNA expression, we explored factors predicting the success of mRNA expression profiling of FFPE material and investigated an approach to overcome the limitation. METHODS Bladder (n=140, stored 3-8 years) and cervix (n=160, stored 8-23 years)(More)
This paper proposes a novel solution to querying hyperlinked multimedia cultural heritage datasets based on the user's context. Context in this sense is defined as the user's location in virtual space and the particular mobile device being modelled together with user preferences or profile. The purpose is to automatically push relevant data from the(More)
BACKGROUND The addition of carbogen and nicotinamide (CON) to radiotherapy (RT) improves overall survival in invasive bladder cancer. We explored whether expression of the hypoxia marker hypoxia-inducible factor-1α (HIF-1α) alone or in combination with other markers predicted benefit from CON. METHODS A retrospective study was carried out using material(More)
BACKGROUND The addition of hypoxia modifiers carbogen and nicotinamide (CON) to radiotherapy (RT) improved overall survival (OS) in bladder cancer patients in the BCON phase III clinical trial. We investigate whether expression of hsa-miR-210 in BCON patient samples reflects hypoxia and predicts benefit from hypoxia modification. METHODS In all, 183(More)
