The first set of subsidiary forts were planned by the Portuguese at Montevideo in 1701 to establish a front line base to stop frequent insurrections by the Spaniards emanating from Buenos Aires. These fortifications were planned within the River Plate estuary at Colonia del Sacramento. However, this plan came to fruition only in November 1723, when Captain Manuel Henriques de Noronha reached the shores of Montevideo with soldiers, guns and colonists on his warship Nossa Senhora de Oliveara. They built a small square fortification. However, under siege from forces from Buenos Aires, the Portuguese withdrew from Montevideo Bay in January 1724, after signing an agreement with the Spaniards.
When were the first set of subsidiary forts planned?
1701

After the war, though, the Continental Army was quickly given land certificates and disbanded in a reflection of the republican distrust of standing armies. State militias became the new nation's sole ground army, with the exception of a regiment to guard the Western Frontier and one battery of artillery guarding West Point's arsenal. However, because of continuing conflict with Native Americans, it was soon realized that it was necessary to field a trained standing army. The Regular Army was at first very small, and after General St. Clair's defeat at the Battle of the Wabash, the Regular Army was reorganized as the Legion of the United States, which was established in 1791 and renamed the "United States Army" in 1796.
In what year was the Legion of the United States established?
1791

Temporal theories offer an alternative that appeals to the temporal structure of action potentials, mostly the phase-locking and mode-locking of action potentials to frequencies in a stimulus. The precise way this temporal structure helps code for pitch at higher levels is still debated, but the processing seems to be based on an autocorrelation of action potentials in the auditory nerve. However, it has long been noted that a neural mechanism that may accomplish a delaya necessary operation of a true autocorrelationhas not been found. At least one model shows that a temporal delay is unnecessary to produce an autocorrelation model of pitch perception, appealing to phase shifts between cochlear filters; however, earlier work has shown that certain sounds with a prominent peak in their autocorrelation function do not elicit a corresponding pitch percept, and that certain sounds without a peak in their autocorrelation function nevertheless elicit a pitch. To be a more complete model, autocorrelation must therefore apply to signals that represent the output of the cochlea, as via auditory-nerve interspike-interval histograms. Some theories of pitch perception hold that pitch has inherent octave ambiguities, and therefore is best decomposed into a pitch chroma, a periodic value around the octave, like the note names in western musicand a pitch height, which may be ambiguous, that indicates the octave the pitch is in.
