OBJECTIVE To investigate error and reaction time consequences of alternating compatible and incompatible steering arrangements during a simulated obstacle avoidance task. BACKGROUND Underground coal mine shuttle cars provide an example of a vehicle in which operators are required to alternate between compatible and incompatible steering configurations. METHODS This experiment examines the p...

Upper ontologies are interesting because describing and representing concepts that can be used across various domains (as opposed to domain ontologies). This feature may enable increased correctness of mappings between domain ontologies, conceptual schema and languages. Unfortunately, there exist various upper ontologies and it is quite difficult to decide or to assess which of them should be u...

It remains controversial whether alloreactive donor-derived natural killer (NK) cells display graft-versus-leukemia reactions after unmodified allogeneic hematopoietic stem cell transplantation (HSCT). The present study evaluated the role of inhibitory killer immunoglobulin-like receptor (KIR) ligand incompatibility using a well-defined and uniform setting of unmodified allogeneic HSCT in 374 p...
