 Question: can you have a heart attack from laughing Context: Some authors use more general definitions of ``positive definite'', including some non-symmetric real matrices, or non-Hermitian complex ones.
 Question: can a positive definite matrix be non symmetric Context: The figure illustrates a deterministic finite automaton using a state diagram. In the automaton, there are three states: S, S, and S (denoted graphically by circles). The automaton takes a finite sequence of 0s and 1s as input. For each state, there is a transition arrow leading out to a next state for both 0 and 1. Upon reading a symbol, a DFA jumps deterministically from one state to another by following the transition arrow. For example, if the automaton is currently in state S and the current input symbol is 1, then it deterministically jumps to state S. A DFA has a start state (denoted graphically by an arrow coming in from nowhere) where computations begin, and a set of accept states (denoted graphically by a double circle) which help define when a computation is successful.

The following year the course would be from New York City, USA, to Paris, France with a 150-mile (240 km) ship passage from Nome, Alaska, across the Bering Strait to East Cape, Siberia, this at a time when ``the motor car is the most fragile and capricious thing on earth.''

Since the National Security Act of 1947, this has been understood to mean all United States Armed Forces. U.S. ranks have their roots in British military traditions, with the President possessing ultimate authority, but no rank, maintaining a civilian status, other than the title of Commander in Chief. The exact degree of authority that the Constitution grants to the President as Commander in Chief has been the subject of much debate throughout history, with Congress at various times granting the President wide authority and at others attempting to restrict that authority.
 Question: is the president the head of the military Context: The lower respiratory tract or lower airway is derived from the developing foregut and consists of the trachea, bronchi (primary, secondary and tertiary), bronchioles (including terminal and respiratory), and lungs (including alveoli).
