thin films of binary bi 0 -teo and bi 0 -v 0 systems were prepared by the thermal co-evaporation technique in a vacuum at room temperature. the optical absorption edge of these systems are studied in the wavelength of 200-800 nm using a perkin-elmer uv/vis spectrophotometer. it is found that the value of n=3/2 in the davis-mott equation is best fitted for the fundamental absorption edge for the...

Social psychologists have shown human decisions to be sensitive to numerous ordinary, possibly nonconscious, situational contingencies, motivating the view that control is largely illusory, and that our choices are largely governed by such external contingencies. Against this view is evidence that self-control and goal-maintenance are regularly displayed by humans and other animals, and evidenc...

Social life consists of making mistakes, then correcting them. The big questions do not concern who makes the fewest mistakes and why, but whether the mistakes are fruitful, how fast people recognize them, and how well they correct them. The same principles apply to writing books, even if the interaction and error-correction take longer to operate than in everyday conversation. This symposium’s...

THEOREM. Let G be a graph on n vertices and an euen number of edges. Then the zero-sum (mod 2) Ramsey numbers are given by {i +2 R(G, ~2) = + 1 +t ifG=Kn, n =0,1(mod4) if all the degrees in G are odd otherwise. 0 (mod 2) This settles several problems raised mainly by Noga Alon, Arie Bialostocki, and Yehuda Roditty.

Eq. (1) defines the distribution of a relation strength for irrelevant data entries φ. Eq. (2) defines an relation strength from the clsuter k to cluster l for relevant data entries. λi, i = 1, 2, . . . , N in Eq. (3) denotes the probability of a relevancy flag variable ri being 1. ri = {0, 1} in Eq. (4) indicates whether the object i is relevant or not. zi = k ∈ {1, 2, . . . } indicates the cl...
