In this paper we present a probabilistic broadcast calculus for mobile and wireless networks whose connections are unreliable. In our calculus, broad-casted messages can be lost with a certain probability, and due to mobility the connection probabilities may change. If a network broadcasts a message from a location, it will evolve to a network distribution(More)
Probabilistic automata (PA) [20] have been successfully applied in the formal verification of concurrent and stochastic systems. Efficient model checking algorithms have been studied, where the most often used logics for expressing properties are based on PCTL [11] and its extension PCTL * [4]. Various behav-ioral equivalences are proposed for PAs, as a(More)
Adsorption of phenanthrene on carbon nanotubes (CNTs) and bioaccessibility of adsorbed phenanthrene were studied in simulated gastrointestinal fluids. Adsorption of phenanthrene on CNTs was suppressed in pepsin (800 mg/L) solution (gastric) and bile salt (500 and 5000 mg/L) fluids (intestinal). In addition to competitive sorption, pepsin and(More)
This paper presents a formal characterisation of safety and liveness properties for fully probabilistic systems. As for the classical setting, it is established that any (probabilistic tree) property is equivalent to a conjunction of a safety and liveness property. A simple algorithm is provided to obtain such a property decomposition for flat probabilistic(More)
In this work, the influence of particle size and surface functional groups on the adsorption behavior of bovine serum albumin (BSA) by three types of oxide nanoparticles (NPs), TiO(2) (50±5 nm), SiO(2) (30±5 nm), and Al(2)O(3) (150±5 nm for α type and 60±5 nm for γ type) was investigated in deionized water, in order to explore their interaction mechanisms(More)
The following full text is a preprint version which may differ from the publisher's version. Abstract. The spectrum of branching-time relations for probabilistic systems has been investigated thoroughly by Baier, Hermanns, Katoen and Wolf (2003, 2005), including weak simulation for systems involving substochastic distributions. Weak simulation was proven to(More)
We introduce a continuous time stochastic broadcast calculus for mobile and wireless networks. The mobility between nodes in a network is mod-eled by a stochastic mobility function which allows to change part of a network topology depending on an exponentially distributed delay and a network topology constraint. We allow continuous time stochastic behavior(More)
