Software watermarking is a tool used to combat software piracy by embedding identifying information into a program. Most existing proposals for software watermarking have the shortcoming that the mark can be destroyed via fairly straightforward semantics-preserving code transformations. This paper introduces path-based watermarking, a new approach to(More)
This paper presents an implementation of the novel water-marking method proposed by Venkatesan, Vazirani, and Sinha in their recent paper A Graph Theoretic Approach to Software Watermarking. An executable program is marked by the addition of code for which the topology of the control-flow graph encodes a watermark. We discuss issues that were identified(More)
In this paper, we discuss graph-theoretic approaches to software watermarking and fingerprinting. Software watermarking is used to discourage intellectual property theft and software fingerprinting is used to trace intellectual property copyright violations. We focus on two algorithms that encode information in software through the use of graph structures.(More)
Modulation of the immune system may be a viable alternative in the treatment of fulminant hepatic failure (FHF) and can potentially eliminate the need for donor hepatocytes for cellular therapies. Multipotent bone marrow-derived mesenchymal stem cells (MSCs) have been shown to inhibit the function of various immune cells by undefined paracrine mediators in(More)

Positron emission tomography (PET) with H2(15)O was used as an in vivo, relatively noninvasive, quantitative method for measuring regional blood flow to hindlimb skeletal muscle of anesthetized dogs. A hydrooccluder positioned on the femoral artery was used to reduce flow, and high-flow states were produced by local infusion of adenosine. Three to four(More)
In this paper we describe and assess the use of the GRAIL knowledge representation in the development of an advanced personalised patient information system. The patient information system uses natural language generation techniques from Artificial Intelligence which enable the content and wording of medical information to be personalised automatically. The(More)
Sepsis remains the major cause of death in patients with major burn injuries. In the present investigation we evaluated the interaction between burn injuries of varying severity and preexisting distant infection. We used Gram-negative bacteria (Pseudomonas aeruginosa and Proteus mirabilis) that were genetically engineered to be bioluminescent, which allowed(More)
