Since 1839, Yale medical students have been writing theses as part of their professional training. It is an introduction to the practice of original research, a demanding and sometimes exhausting pursuit. The thesis project promotes a tenacity well suited for the practice of medicine. The thesis advisor has a challenging role as well — one that can only be filled by an individual whose dedicati...

We derived explicit formulae for the eccentric connectivity index and Wiener index of 2-dimensional square-octagonal TUC4C8(R) lattices with open and closed ends. New compression factors for both indices are also computed in the limit N-->∞.

Let $G$ be a connected graph on $n$ vertices. $G$ is called tricyclic if it has $n + 2$ edges, and tetracyclic if $G$ has exactly $n + 3$ edges. Suppose $mathcal{C}_n$ and $mathcal{D}_n$ denote the set of all tricyclic and tetracyclic $n-$vertex graphs, respectively. The aim of this paper is to calculate the minimum and maximum of eccentric connectivity index in $mathcal{C}_n$ and $mathcal{D}_n...

Wireless sensor networks are often located in areas where access to them is difficult or dangerous. Today, in wireless sensor networks, cluster-based routing protocols by dividing sensor nodes into distinct clusters and selecting local head-clusters to combine and send information of each cluster to the base station and balanced energy consumption by network nodes, get the best performance ...

Based on the associated network of passenger and freight transport in New Western Land-Sea Corridor, structure characteristics different years are analyzed using volume volume, resilience is disturbance model. Finally, coordinated development logistics discussed by applying a coupling coordination The results show that, from 2000 to 2018, Corridor has realized evolution spatial pattern “two cen...

On October 25 and 26, 2007, at the University of Toronto, the Gairdner Foundation in partnership with Canadian Institutes of Health Research presented a two-day international symposium titled Minds That Matter. The symposium featured academic lectures by Gairdner Award winners past and present and by other leading biomedical scientists. These distinguished researchers share many characteristics...

let $gamma_{n,kappa}$ be the class of all graphs with $ngeq3$ vertices and $kappageq2$ vertex connectivity. denote by $upsilon_{n,beta}$ the family of all connected graphs with $ngeq4$ vertices and matching number $beta$ where $2leqbetaleqlfloorfrac{n}{2}rfloor$. in the classes of graphs $gamma_{n,kappa}$ and $upsilon_{n,beta}$, the elements having maximum augmented zagreb index are determined.

Much within the profession of massage therapy is done according to tradition. From an epistemological viewpoint, tradition is a way of knowing or, by extension, being, that is based upon both tenacity and authority and not always in best practices. As the profession of massage therapy moves in the direction of evidence-based medicine, or evidence-informed practice, the opportunity to re-evaluat...
