A universal Turing machine \(U\) is a Turing machine that can imitate the behavior of any other Turing machine \(T\ .\) It is a fundamental result that such machines exist and can be constructed effectively.Only a suitable description of \(T\)'s finite program and input needs to be entered on \(U\)'s tape initially.uring gave a brilliant demonstration that everything that can be reasonably said to be computed by a human computer using a fixed procedure can be computed by such a machine. As Turing claimed, any process that can be naturally called an effective procedure is realized by a Turing machine.
Dysautonomia is a term for a group of diseases that include postural orthostatic tachycardia syndrome (POTS), multiple system atrophy, autonomic failure, and autonomic neuropathy. In these conditions the autonomic nervous system (ANS) does not work properly.
In many cases treatment of primary dysautonomia is symptomatic and supportive. Measures to combat orthostatic hypotension include elevation of the head of the bed, frequent small meals, a high-salt diet, and drugs such as fludrocortisone, midodrine, and ephedrine.atients with chronic, progressive, generalized dysautonomia in the setting of central nervous system degeneration have a generally poor long-term prognosis. Death can occur from pneumonia, acute respiratory failure, or sudden cardiopulmonary arrest in such patients.
