Critical-care medicine requires rapidity of treatment decisions and clinical management. To meet the objectives of critical-care medicine, the critical-care laboratory must consider four major aspects of laboratory organization in addition to analytical responsibilities: specimen collection and delivery, training of technologists, selection of reliable instrumentation, and efficient data dissem...

As workflow management systems become more complex and critical to an organisation’s performance, there is an opportunity for a new generation of workflow management products. These products could greatly increase the scope of workflow management systems in target application areas. One of the key extensions to workflow management systems will be the use of transactional semantics to increase r...

The specification of business processes is becoming a more and more critical aspect for organizations. Such processes are specified as workflow models expressing the logical precedence among the different business activities (i.e., the units of work). Up to now, workflow models have been commonly managed through specific subsystems, called workflow management systems. In this paper we advocate ...

INTRODUCTION E-consultations are asynchronous text-based consultations between providers which can facilitate patient access to timely specialty care. In contrast to traditional face-to-face consults, conveying and completing recommendations of the specialist is the responsibility of the referring provider. This presents a new workflow for primary care providers who have multiple options (face-...

This paper highlights the need for adaptive workflow management, classifies various types of workflow adaptation, and discusses potential mechanisms for achieving adaptive workflow management. Our current efforts on adaptive workflow research are presented with emphasis laid on human involvement. The developments are based on dynamic composition of workflow resources, including workflow models,...

Consider cotangent bundles of exotic spheres, with their canonical symplectic structure. They admit automorphisms which preserve the part at infinity of one fibre, and which are analogous to the square of a Dehn twist. Pursuing that analogy, we show that they have infinite order up to isotopy (inside the group of all automorphisms with the same behaviour).

For any knot T transverse to a given contact structure on a 3-manifold, we exhibit a Legendrian two-component link L = L1 t L2 such that T equals the transverse push-off of L1 and contact (+1)surgery on L has the same effect as a Lutz twist along T .

There is an ongoing debate in the workflow community about the relative merits of Petri nets and π-calculus for workflow modeling. Recently, van der Aalst presented some challenges to model workflow in π-calculus. This paper responds to those challenges by showing how to code the 20 most commonplace workflow patterns in CCS (a subset of π-calculus), and describes two new workflow patterns that ...

Business processes are crucial for every organisation as they represent the core value generating processes. Managing business processes is important to be efficient and to compete with a globalized market. Business process monitoring is an essential means to understand and to improve working procedures. It helps detecting deviations from planned procedures and brings transparency into the stat...
