Choosing a sheltered middle path

Choosing a Sheltered Middle Path

We say that point x ∈ R2 is sheltered by a continuum S ⊂ R2 if x does not belong to the unbounded component of R2 \ S. Suppose that points a and b are the endpoints of each of three arcs A0, A1 and A2 contained in R2. We prove that there is an arc B ⊂ A0 ∪A1 ∪A2 with its endpoints a and b such that each point of B is sheltered by the union of each two of the arcs

Choosing a Shortest Path Algorithm

Computation of shortest paths is an integral component of many applications such as transportation planning and VLSI design. Frequently, a shortest path algorithm is selected for a given application based on the performance of the algorithm for a set of test networks. The performance of this algorithm, however, can be signiicantly diierent for networks not included in the test set. Therefore, i...

Choosing a Post-Fellowship Path

While the gastroenterology career path is by no means short, for many of us it was relatively straightforward. If, like me, you knew you wanted to pursue gastroenterology, you moved from medical school to residency to fellowship relatively seamlessly, without need for significant pause or reflection. Yet during fellowship, there is a looming fork in the road. Mentors ask about your career goals...

Choosing Development Path According to Priority Power: Determination of key sector for Iran economy

Resources’ scarcity, especially in developing countries, has caused allocation essentially among competing activities to create value. The importance of resource allocation would be more understood if we pay attention to growing complexity in societies and economic development problems they face. In the context of the national economic development literature, the notion of “Key or Critical Sect...
