Human Experimentation: a Guided Step into the Unknown

Experimentation: the next step.

General practice has entered a period of accelerating change, and those responsible for planning its development now put forward a variety of promising proposals. Unless provision is made for large scale experimentation and scientific evaluation, the direction of future change will be determined not by evidence but by rhetoric. A framework for creating and evaluating a substantial programme of ...

PolyU's Experimentation with Guided Summarization

In addition to the familiar tasks of update summarization and automatic summary evaluation, the TAC 2010 summarization track includes a new task: guided summarization. It is designed to “encourage a deeper linguistic (semantic) analysis of the source documents” in order to generate a summary guided by a given set of aspects. The new task is an upgrade of query-focused summarization in that an a...

Experimentation with a Big-Step Semantics for ATL Model Transformations

Formal semantics is a convenient tool to equip a model transformation language with precise meaning for its model transformations. Hence, clarifying their usage in complex scenarios and helping in the development of robust model transformation engines. In this paper, we focus on the formal specification of a model transformation engine for the declarative part of ATL. We present an implementati...

brief azacytidine step allows the conversion of suspension human fibroblasts into neural progenitor-like cells

in recent years transdifferentiation technology has enabled direct conversion of human fibroblasts to become a valuable, abundant and accessible cell source for patient-specific induced cell generation in biomedical research. the majority of transdifferentiation approaches rely upon viral gene delivery which due to random integration with the host genome can cause genome instability and tumorig...
