BACKGROUND Although proximal right coronary artery (RCA) occlusion is the culprit commonly responsible for acute right ventricular (RV) infarction (RVI), the severity of RV dysfunction ranges broadly. This study was designed to delineate the patterns of coronary compromise that determine the magnitude of RV ischemic dysfunction. METHODS AND RESULTS In 125 patients with acute inferior myocardi...

A complex variation in the pattern of blood supply to the palm of the hand was encountered during a routine dissection of a female adult cadaver. Findings were: (a) there was no communication between the superficial palmar branches of the radial and ulnar arteries (incomplete superficial palmar arch); (b) the superficial palmar branch of the radial artery coursed superficially to the thenar mus...

Chemical Graph Theory is a branch of Mathematical Chemistry whose focus interest to finding topological indices chemical graphs which correlate well with properties the molecules. In this study, we define edge version Sombor index, modified index and, Nirmala graph and compute exact formulas for certain families nanotubes nanotori.

RNA molecules with internal 2',5'-branches are intermediates in RNA splicing, and branched RNAs have recently been proposed as retrotransposition intermediates. A broadly applicable in vitro synthetic route to branched RNA that does not require self-splicing introns or spliceosomes would substantially improve our ability to study biochemical processes that involve branched RNA. We recently desc...

RNA molecules with internal 20,50-branches are intermediates in RNA splicing, and branched RNAs have recently been proposed as retrotransposition intermediates. A broadly applicable in vitro synthetic route to branched RNA that does not require selfsplicing introns or spliceosomes would substantially improve our ability to study biochemical processes that involve branched RNA. We recently descr...

This paper introduces the Pyramidal Capacitated Vehicle Routing Problem (PCVRP) as a restricted version of the Capacitated Vehicle Routing Problem (CVRP). In the PCVRP each route is required to be pyramidal in a sense generalized from the Pyramidal Traveling Salesman Problem (PTSP). A pyramidal route is defined as a route on which the vehicle first visits customers in increasing order of custom...

The paper proposes several dynamic bandwidth allocation strategies for QoS routing on TDMA-based mobile ad hoc networks. Comprehensively, these strategies are called a distributed slots reservation protocol (DSRP). In DSRP, QoS routing only depends on one-hop neighboring information of each mobile host (MH). In addition, slot inhibited policies (SIPs) and slot decision policies (SDPs) are propo...

Effective route planning for battery electric commercial vehicle (ECV) fleets has to take into account their limited autonomy and the possibility of visiting recharging stations during the course of a route. In this paper, we consider four variants of the electric vehicle-routing problem with time windows: (i) at most a single recharge per route is allowed, and batteries are fully recharged on ...

Topological indices are empirical features of graphs that characterize the topology graph and, for most part, independent. An important branch theory is chemical theory. In theory, atoms corresponds vertices and edges covalent bonds. A topological index a numeric number represents underline structure. this article, we examined properties prism octahedron network dimension <math xmlns="http://ww...
