Restricted walks

In Parkinson’s disease (PD) population, performing secondary tasks while walking further deteriorates gait and restrict mobility in functional contexts of daily life. This study (1) analyzed the interference of functional cognitive and motor secondary task on untrained people with PD and (2) compared their walking with healthy subjects.

Although the Flow of Funds data are available only after 1945, it is clear from Figure 3 that the market value of NYSE companies as a fraction of the market value of all U.S. companies has been remarkably constant. The total market value of all domestic corporations is about 1.45 times the market value of NYSE companies. Notice that these values are very close for the entire post-World War II period — not only on average but at peaks and troughs too. If we assume that the ratio is roughly 1.45 in the pre-World War II period as well, we can use the NYSE values to...

Let T be an innite regular tree and n a positive integer. Fix two vertices x and y in T . By a walk or a path between x and y we mean any nite sequence of edges that connect x and y in which backtrackings are allowed. There are many formulas in the literature which give the number of walks of length n between x and y, such as recurrence formulas, generating functions, Green functions, and others. Here we consider walks of length n between x and y which at a certain time follow a number of predetermined steps....
