Long Walk: The Day Before

Walk a day in my shoes.

Simple expressions for the long walk distance

The walk distances in graphs are defined as the result of appropriate transformations of the ∑∞ k=0(tA) k proximity measures, where A is the weighted adjacency matrix of a connected weighted graph and t is a sufficiently small positive parameter. The walk distances are graph-geodetic, moreover, they converge to the shortest path distance and to the so-called long walk distance as the parameter ...

Long-time entanglement in the Quantum Walk

The coin-position entanglement generated by the evolution operator of a discrete–time quantum walk is quantified, using the von Neumann entropy of the reduced density operator (entropy of entanglement). In the case of a single walker, the entropy of entanglement converges, in the long time limit, to a well defined value which depends on the initial state. Exact expressions are obtained for loca...

Walk your way to health: October 15 – World Walking Day

As defined by the World Health Organization (WHO), physical activity is “any bodily movement produced by skeletal muscles that requires energy expenditure.” It is one of the fundamental functional stimuli to the body, which, if regularly applied, reduces the risk of developing a series of chronic, primarily cardiovascular, diseases, certain types of cancer, non-insulin-dependent diabetes, and o...

Vocal Assessment Before, After, and the Day After Opera Performance.

OBJECTIVE To explore aerodynamic, acoustic, and laryngeal changes surrounding opera performance. STUDY DESIGN Prospective preperformance, postperformance, and day after performance. METHODS The laryngeal and vocal function of five male and five female classically trained singers was assessed immediately before, immediately after, and 1 day after an actual operatic performance. Phonatory thr...
