Scientists have discovered a new exoplanet that, in the language of “Star Wars,” would be the polar opposite of frigid Hoth, and even more inhospitable than the deserts of Tatooine. But instead of res...
A Fatou–Bieberbach domain avoiding a neighborhood of a variety of codimension 2.
Urban forestry is a very important element of urban structures that can improve the environment and life quality within the urban areas. Having an accurate classification of urban forests and grass ar...
The strategy is paying off. At the American Astronomical Society (AAS) meeting in Seattle this week, researchers reported early successes from the All-Sky Automated Survey for Supernova...
Here we present 1584 new southern proper motion systems with mu > 0.18 "/yr and 16.5 > R_59F > 18.0. This search complements the six previous SuperCOSMOS-RECONS (SCR) proper motion searches of the sou...
We estimate the Lyapunov times (characteristic times of predictabil-ity of motion) in Quillen's (2003) set of models for the dynamics in the Solar neighborhood.
We define the block neighborhood of a reversible CA, which is related both to its decomposition into a product of block permutations and to quantum computing. We give a purely combinatorial characteri...
We consider a $\pi$-mode solution of the Fermi-Pasta-Ulam $\beta$ system. By perturbing it, we study the system as a function of the energy density from a regime where the solution is stable to a regi...
Comparison of Solar Motion relative to Stars of Different Color Index in the Solar Neighborhood
Making use of the familiar convolution structure of analytic functions, in this paper we introduce and investigate two new subclasses of multivalently analytic functions of complex order. Among the va...
In the present paper, the authors prove several inclusion relations associated with the -neighborhoods of certain subclasses of -valently analytic functions of complex order, which are introduced here...
By means of a certain extended derivative operator of Ruscheweyh type, the authors introduce and investigate two new subclasses of p-valently analytic functions of complex order. The various results o...
n(Y) for each Y∈I^*_{k+1}(G), then G is Hamilton-connected. The existing results are generalized by these since I_{k+1}(G) is replaced by I^*_{k+1}(G). We introduce a new technique of T-insertion in t...
Let G be a 2-connected simple graph of order n. In this paper we prove the following generalization of Ore's theorem: If G is a 2-connected graph such that |N(u) \cup N(v)|+|N(u) \cup N(w)| ≥ n for ev...
Let C be a 2-connected graph on n\geq 31 venices. G is called pancyclic if itcontains a cycle of length for every l such that 3\leq l \leq n. In this paper we shall prove that if |N(u)\cup N(v)| \geq...
