A bstract The state-of-the-art in current two-loop QCD amplitude calculations is at five-particle scattering. Computing six-particle processes requires knowledge of the corresponding one-loop amplitudes to higher orders dimensional regulator. In this paper we compute analytically hexagon integral via differential equations. particular identify its function alphabet for general D -dimensional ex...

background: sentinel  lymph  node  biopsy  has  shown  to  be  a  good  alternative procedure  for  axillary  lymph  node  dissection  and  to lead  to  lower  frequency  of morbidity, though this technique has its own side effects. it needs especial equipment and may not be available in some medical centers, especially in developing countries. this study aimed to identify a subgroup of patient...

When it was proclaimed that the Library contained all books, the first impression was one of extravagant happiness. All men felt themselves to be the masters of an intact and secret treasure. There was no personal or world problem whose eloquent solution did not exist in some hexagon. (. . . ) As was natural, this inordinate hope was followed by an excessive depression. The certitude that some ...

An edge tessellation of the plane is generated by the reflection of some polygon in its edges. We prove that a polygon generating an edge tessellation is exactly one of the following: An equilateral, 30-right, isoceles right, or 120-isoceles triangle, a rectangle, a 60-rhombus, a 60-90-120-kite, or a regular hexagon. The results in this paper were discovered by Millersville University students ...

While the phrase “six degrees of separation” is widely used to characterize a variety of humanderived networks, in this study we show that in patent citation network, related patents are connected with an average distance of 6, whereas an average distance for a random pair of nodes in the graph is approximately 15. We use this information to improve the recall level in prior-art retrieval in th...

This paper will discuss the role of networks in cognition on two levels: on the level of the organization of ideas, and on the level of interpersonal communication. By way of introduction, however, let me refer to the level which is the most basic: that of neurophysiological organization. The adult brain has around 100 billion neurons, linked to each other by axons. Most axons connect nearby ne...
