Research into the maintenance of procedural knowledge has focused on the detection of declarative meta-structures within the procedures. An alternative approach is described here based on the ripple-down-rules (RDR) formalism. To the standard RDR rule tree, we add a functions environment hierarchy that stores the implementation of the procedures used in the rules. This functions environment str...

Adaptable software systems and architectures give the programmer the ability to create applications that might customize themselves to runtime-emerging requirements. Computational reflection is a programming language technique that is commonly used to achieve the development of this kind of systems. Most runtime reflective systems use meta-object protocols (MOPs). However, MOPs restrict the amo...

The XML port scanning technique described in this paper allows an attacker to utilise an XML parser to execute port scanning of systems behind a restrictive perimeter firewall. While the technique relies on some reasonably specific implementation details in order to be exploitable remotely, it is potentially applicable to any application that accepts XML document inputs. Several workarounds exi...

Methods A total of 43 consecutive patients (age 44 10 years) with moderate to severe PVS referred to Royal Brompton Hospital from 2002 to 2005 were retrospectively studied. Patient New York Heart Association (NYHA) functional class was recorded. The RV (lateral tricuspid annulus motion) long-axis movement was measured by M-mode and pulsed-wave (PW) tissue Doppler imaging (TDI). Restrictive RV p...

in this paper, we examine the treatment of persian relative clauses in role and reference grammar. rrg is a structural-functional theory which has studied the syntax-semantics-pragmatics interface in human language systems. the main objectives of this article, on the one hand, are to elucidate syntactic, semantic and pragmatic properties of farsi relative clauses, and on the other hand, to asse...

Restrictive cardiomyopathies may have different etiologies, among which we can point out storage diseases by accumulation of different materials such as desmin. Desminopathies are uncommon diseases that progress with conduction abnormalities, peripheral myopathies, and ventricular dysfunction. The present report describes a patient with complete atrioventricular block as the initial event; he l...

This report details the clinical, hemodynamic, and morphologic data from four patients 59 to 77 years old (mean 66) with a primary restrictive cardiomyopathy. All patients had symptoms of congestive heart failure, jugular venous distention, and murmurs of mitral and tricuspid regurgitation. Four patients required pacemakers, three for the brady-tachy syndrome and one for complete heart block. C...

This paper presents the results of a corpus study which reveals the frequency of restrictive post-modification on definite descriptions in English language texts (newspaper articles). It shows that restricted descriptions are usually first mention uses (nonanaphoric) and that these can be systematically identified. The paper then compares features of restricted descriptions with bridging refere...
