A novel stimulating protocol was used to demonstrate the existence of a biphasic inhibitory reflex in single soleus motor neurones in response to weak stimulation of the tibial nerve in human subjects. The stimulus intensity was sufficient to evoke a small M-response but was subthreshold for the H-reflex. Stronger stimulation caused the 2 phases of(More)
The reflex responses of single motor units in the soleus muscle to electrical stimulation of the tibial nerve were recorded in human volunteers. A feature of the experiments was the stimulation paradigm used. In order to control the peri-stimulus firing rate, a computer triggered the stimulus isolator only when 2 interspike intervals of specified duration(More)
BACKGROUND An estimated 120,000 HIV-associated cryptococcal meningitis (CM) cases occur each year in South and Southeast Asia; early treatment may improve outcomes. The World Health Organization (WHO) recently recommended screening HIV-infected adults with CD4<100 cells/mm(3) for serum cryptococcal antigen (CrAg), a marker of early cryptococcal infection,(More)
We propose a new dynamic row/column management algorithm for freight train scheduling in a single track railway system. While many papers have already been devoted to train scheduling, previously published optimization models still suffer from scalability issues, even for single track railway systems. Moreover, very few of them take into account the(More)
