An important problem for forestry in-field chipping operations is the efficient daily truck transportation of chips from different coupes being harvested, with known supplies, to customer destinations with known daily demands. This paper presents initial results from a trial with FastTRUCK, a software tool that uses a simulated annealing approach to optimise truck schedules. The software was de...

U recently, conventional wisdom has held that the lineage potential of stem cells was restricted to the tissue of origin. That is, stem cells derived from tissue A could only give rise to differentiated cells of tissue A and not to differentiated cells of tissues B, C, or D. This notion has been challenged since by a plethora of reports suggesting that stem cells have an inherent plasticity tha...

In clinical cardiology, therapy for the most part is still primarily palliative, whereas relatively few procedures are truly curative. In the early days of invasive electrophysiology, clinicians were excited about the ability to induce supraventricular tachycardia with single, critically timed atrial extrastimuli.1 Soon thereafter, a whole array of mechanisms that induced these tachycardias bec...

Survivors of acquired brain injury (ABI) are at risk of a range of neuropsychiatric and behavioural disorders. Emotional disturbance, with reactive elements of mood disorder, such as depression and anxiety, appear particularly common. Specific anxiety disorders, such as post-traumatic stress disorder (PTSD) have also been identified. Pain syndromes are also common-particularly in those who have...
