Felicity Stout’s monograph Exploring Russia in the Elizabethan Commonwealth incorporates elements of her PhD thesis and is a welcome addition to the discussion of Elizabethan political culture and England’s mercantile interactions with Muscovy in the late 16th century.(1) Exploring the themes of commonwealth, corruption and tyranny, the book draws upon Giles Fletcher’s experiences and writings ...

The reciprocal complementary Wiener number of a connected graph G is defined as ( ) { } ( ) ( ) | ∑ u v V G RCW G d d u v G ⊆ = + − , 1 1 , where ( ) V G is the vertex set. ( ) | d u v G , is the distance between vertices u and v, and d is the diameter of G. A tree is known as a caterpillar if the removal of all pendant vertices makes it as a path. Otherwise, it is called a non-caterpillar. Amo...

In response to the rise in construction defect litigation and the resulting increase in the cost of insurance contractors are required to carry, the Washington Legislature passed RCW 64.50.005 et seq., which became effective June 13, 2002. The statute (referred to by some as a “bill of rights” for contractors) requires that homeowners and condominium homeowners’ associations (collectively “home...

Recent observations of 1E 161348-5055 the neutron-star candidate at the center of the supernova remnant RCW 103, show that a component of its emission varies sinusoidally with a period of approximately six hours. We argue that this period is what one would expect for a freely precessing neutron star with a spin period of about one second. We produce light curves for a freely precessing neutron ...

We review the properties of the very young (∼ 2 Myr) open cluster NGC 6383. The cluster is dominated by the massive binary HD 159176 (O7 V + O7 V). The distance to NGC 6383 is consistently found to be 1.3 ± 0.1 kpc and the average reddening is determined to be E(B−V ) = 0.32 ± 0.02. Several pre-main sequence candidates have been identified using different criteria relying on the detection of em...
