following the formation of the persian empire by cyrus the great and its extension by darius i, from indus river in india to nile in egypt, persian kings felt that there is a need to use an international language to be understandable by all nations of this great empire. this need was greater when they sent orders and messages to these different nations. when darius i defeated his enemies and su...

A boolean term order is a total order on subsets of [n] = {1,. .. , n} such that ∅ ≺ α for all α ⊆ [n], α = ∅, and α ≺ β ⇒ α ∪ γ ≺ β ∪ γ for all γ with γ ∩ (α ∪ β) = ∅. Boolean term orders arise in several different areas of mathematics, including Gröbner basis theory for the exterior algebra, and comparative probability. The main result of this paper is that boolean term orders correspond to o...

We study the computable structure theory of linear orders of size א1 within the framework of admissible computability theory. In particular, we characterize which of these linear orders are computably categorical.

background: low compliance with drugs regimens in diabetic patients is one of the greatest challenges in the treatment of diabetes. the aim of this study was to evaluate compliance with medical orders in diabetic patients referred to the endocrinology clinic of afzalipour hospital, kerman, iran. methods: in this cross sectional study 345 of the 3000 patients, who referred to the endocrinology c...

0. Abstract First we prove that the set of countable linear orders of the form I +I form a complete analytic set. As a consequence of this we improve a result of Humke and Laczkovich, who showed in HL] that the set of functions of the form f f form a true analytic set in C0; 1]. We show that these functions form a complete analytic set, solving a problem mentioned on p.215 of K] and on p.4 of B].
