Can Probabilities Be Mimicked by Rules?
We examine the expressive power of probabilistic context free grammars (PCFGs), with a special focus on the use of probabilities as a filtering mechanism. Probabilities in PCFGs induce an ordering relation among the set of trees yielding a given input sentence. PCFG parsers return the trees bearing the maximum probability for a given sentence, discarding all other possible trees. Obviously, thi...
متن کاملHypothermic Preconditioning Reverses Tau Ontogenesis in Human Cortical Neurons and is Mimicked by Protein Phosphatase 2A Inhibition
Hypothermia is potently neuroprotective, but the molecular basis of this effect remains obscure. Changes in neuronal tau protein are of interest, since tau becomes hyperphosphorylated in injury-resistant, hypothermic brains. Noting inter-species differences in tau isoforms, we have used functional cortical neurons differentiated from human pluripotent stem cells (hCNs) to interrogate tau modula...
متن کاملMultidimensionality in host manipulation mimicked by serotonin injection.
Manipulative parasites often alter the phenotype of their hosts along multiple dimensions. 'Multidimensionality' in host manipulation could consist in the simultaneous alteration of several physiological pathways independently of one another, or proceed from the disruption of some key physiological parameter, followed by a cascade of effects. We compared multidimensionality in 'host manipulatio...
متن کاملForeign Accent Syndrome Mimicked by Garcin Syndrome with Spontaneous Resolution
An English speaking women developed a French accent, without any aphasic syndromes, in conjunction with multiple left sided cranial nerve deficits, temporally related to cranial trauma. Extensive testing with multimodality magnetic resonance imaging, cerebrospinal fluid and laboratory analysis was unremarkable. She was followed over a 3 year period during which her French accent resolved as did...
متن کاملAntiarrhythmic drug effect mimicked by spontaneous variability of ventricular ectopy.
Twenty patients with frequent ventricular ectopic beats had a 5 1/2 hour ECG rhythm strip recorded. Individual patients showed a marked spontaneous variability from one half-hour to the next in the total number of ectopic beats (-99% to +1100%) and the occurrence of pairs or salvos. Although no patient received antiarrhythmic drugs, some patients showed a spontaneous change in arrhythmia which ...
