we have studied the effect of hypothetical cosmions on the core stability of main sequence stars (of populations i and ii). cosmions, with a mass of 4-10 gev/c2 and a scattering cross section with nucleons of approximately 10-36 cm2 could prevail in transporting heat in the stellar cores. raby [17] showed the existence of a local thermal instability caused by the presence of cosmions in the sol...

We present new high resolution (R ≃ 18, 000) near-infrared spectroscopic observations of a sample of classical FU Orionis stars (FUors) and other young stars with FUor characteristics that are sources of Herbig-Haro flows. Spectra are presented for the region λ = 2.203 – 2.236 μm which is rich in absorption lines sensitive to both effective temperatures and surface gravities of stars. Both FUor...

ABSTRACT A vibrant and commercially active center is often the result of interesting, diverse building styles and or built-forms, pedestrian density along with variety of quality public places where people feel comfortable, spending time and shopping items for domestic and commercial functions in cities like Addis Ababa. The scale and design of buildings, pedestrian density, and other phy...

A method is presented for representation of and inference on probabilistic models based on local, structured, symbolic representations of uncertainty of propositions of interest. An example is provided of the intended use of this technique, and it is argued that it is a more direct and efficient basis for the construction of probiem solvers than standard representation and inference methods. Th...
