To explain Gamma Ray Bursts, Ruffini argued that the event horizon of a charged black hole is surrounded by a special region called, the Dyadosphere where electric field exceeds the critical value for e+ e− pair production. In the present work, we construct a thin shell wormhole by performing a thought surgery between two dadospheres. Several physical properties of this thin shell wormhole have...

In this paper, we consider the number of 2-protected nodes in random digital trees. For tries, Gaither, Homma, Sellke and Ward (2012) and Gaither and Ward (2013) derived asymptotic expansions for mean and variance. We re-derive their results (with some corrections) and show their conjectured central limit theorem. This will be done by recent unified approaches by Fuchs, Hwang and Zacharovas (20...

In this paper, we consider a generalized Catalan triangle de…ned by km n 2n n k for positive integer m: Then we compute the weighted half binomial sums with the certain powers of generalized Fibonacci and Lucas numbers of the form n X k=0 2n n+ k km n X tk; where Xn either generalized Fibonacci or Lucas numbers, t and r are integers for 1 m 6: After we describe a general methodology to show how...

In letters [1] to one of us (Fielder) in mid-1977, the late Verner Hoggatt conjectured that the third diagonal of Pascal's triangle could be used in a simple algorithm to generate rows of integers whose row sums equaled correspondingly indexed Baxter permutation values (see [3], [4]). Later, in 1978, Chung, Graham, Hoggatt, and Kleiman produced a remarkable paper [2] in which they derived a gen...

An overview of the ‘triangle’ method for estimating soil surface wetness and evapotranspiration fraction from satellite imagery is presented here. The method is insensitive to initial atmospheric and surface conditions, net radiation and atmospheric correction, yet can yield accuracies comparable to other methods. We describe the method first from the standpoint of the how the triangle is obser...

PURPOSE To compare the intraocular pressure measurements as defined by the Pascal tonometer, the Goldmann tonometer and the pneumotonometer. METHODS This was an observational clinical study, which included two hundred and five randomly selected subjects recruited from the Ophthalmology Department. The intraocular pressure measurements were performed with each tonometry technique in a randomiz...
