We consider πI, a fragment of the π-calculus where only exchange of private names among processes is permitted (internal mobility). The calculus πI enjoys a simpler mathematical treatment, very close to that of CCS. In particular, πI avoids the concept of substitution. We provide an encoding from the asynchronous π-calculus to πI and then prove that two processes are barbed equivalent in π-calc...

Supragingival calculus predisposes to the development of periodontal disease by providing a retentive surface for plaque bacteria and impeding attempts to maintain an effective level of plaque control (47). Although the presence of calculus and gingival inflammation, as evidenced by bleeding on probing, are not always coincident (1) the close proximity of supragingival calculus to the gingiva e...

In the present paper, we introduce a multi-type display calculus for dynamic epistemic logic, which we refer to as Dynamic Calculus. The displayapproach is suitable to modularly chart the space of dynamic epistemic logics on weaker-than-classical propositional base. The presence of types endows the language of the Dynamic Calculus with additional expressivity, allows for a smooth proof-theoreti...

Formal methods for the verification of safety-critical systems are an area of active research. In this thesis we investigate systems involving mobility and real-time constraints. For the description of many mobile real-time systems both spatial and temporal aspects need to be considered. There are several well-understood methods for the formal treatment of real-time aspects among them the Durat...

INTRODUCTION The prevalence of lower urinary tract symptoms (LUTS) is about 20% in men aged 40 or above. Other than benign prostatic hyperplasia (BPH), urethral diverticulum or calculus is not uncommon for LUTS in men. Surgical treatment is often recommended for urethral diverticulum or calculus, but treatment for an impacted urethral calculus complicated by a stone-containing diverticulum is c...

In many theorem proving applications, a proper treatment of equational theories or equality is mandatory. In this paper we show how to integrate a modern treatment of equality in the Model Evolution calculus (ME), a first-order version of the propositional DPLL procedure. The new calculus, MEE, is a proper extension of the ME calculus without equality. Like ME it maintains an explicit candidate...
