The clinical setting is a significant learning environment for undergraduate nursing students. However, the learning that occurs in this environment presents challenges that may cause students to experience stress and anxiety. High levels of anxiety can affect students' clinical performance, presenting a clear threat to success in a clinical rotation. It is crucial for clinical nursing faculty ...

In this paper we offer a methodology for verifying correctness of (timed) security protocols whose actions are parametrized with time. To this aim the model of a protocol involves delays and timeouts on transitions, and sets time constraints on actions to be executed. Our approach consists in specifying a security protocol, possibly with timestamps, in a higher-level language and translating au...

One protocol (called the primary protocol) is independent of other protocols (jointly called the secondary protocol) if the question whether the primary protocol achieves a security goal never depends on whether the secondary protocol is in use. In this paper, we use multiprotocol strand spaces ([27], cf. [28]) to prove that two cryptographic protocols are independent if they use encryption in ...

The correspondence between the steady-state theory of current transfer and scattering theory in a system of coupled tight-binding models of one-dimensional wires is explored. For weak interwire coupling both calculations give nearly identical results, except at singular points associated with band edges. The effect of decoherence in each of these models is studied using a generalization of the ...
