It is well known that significant variations in stomach size, shape, and respiratory motion lead to uncertainties in target localization during treatment for gastric lymphoma. In this study, the usefulness of 4D-CT for radiation planning of gastric MZBCL/MALT was evaluated. Treatment planning using 4DCT (plan A) and conventional planning with a uniform margin (plan B) were compared using dose v...

The purpose of this study is to investigate the potential benefits of conformal radiotherapy (CRT) combined with a sequential volumetric-modulated arc therapy (VMAT) boost in the treatment of upper thoracic esophageal cancer. Ten patients with upper thoracic esophageal cancer previously treated with CRT plus a sequential VMAT boost plan were replanned with CRT plus an off-cord CRT boost plan an...

BACKGROUND Physicians require specific communication skills, because the face-to-face contact with their patients is an important source of information. Although physicians who perform work disability assessments attend some communication-related training courses during their professional education, no specialised and evidence-based communication skills training course is available for them. Th...

In this paper, we address the problem of generating preferred plans by combining the procedural control knowledge specified by Hierarchical Task Networks (HTNs) with rich user preferences. To this end, we extend the popular Plan Domain Description Language, PDDL3, to support specification of preferences over HTN constructs. To compute preferred HTN plans, we propose a branch-and-bound algorithm...

This paper presents the design and implementation of a course of action (COA) ontology for counterinsurgency (COIN) operations. This ontology supports the commander’s C2 decision making processes for COA design, analysis and selection and represents the key elements of the COA planning process; specifically measures-of-performance (MOP) and measures-of-effectiveness (MOE) for describing COA pla...

Mass collaboration involving large number of people working and learning together is emerging in the digitally networked environment. Socio-technical environments fostering mass collaboration are facilitated by the technical infrastructure of the Internet, and they support collaborating participants to solve problems, share information, and engage in the joint construction of artifacts and know...
