For every Scott set F and every nonrecursive set X in F , there is a Y ∈ F such that X and Y are Turing incomparable.

We begin with a graph (or a directed graph), a single set of nodes N , and a set of lines or arcs L. It is common to use this mathematical concept to represent a network. We use the notation of [1], especially Chapters 13 and 15. There are extensions of these ideas to a wide range of networks, including multiple relations, affiliation relations, valued relations, and social influence and select...

‎This paper develops a basic theory of $H$-groups‎. ‎We‎ ‎introduce a special quotient of $H$-groups and‎ ‎extend some algebraic constructions of topological groups to the category‎ ‎of H-groups and H-maps and then present a functor from this category to the category of quasitopological groups‎.

Various plant organ segments including segments from roots (root tip, and root collar), stems, leaves, and also seeds of several Hyoscyamus species (i.e. H. pusillus, H. arachnoideus, annual and biennial H. niger from two distinct geographical regions) were cultured on MS media with various growth regulator combinations, to assess the ability of flower production. Statistical assessments showed...

مقالة حاضر بر آن است که اصطلاح نوآورانة «درون‌متنیت» را معرفی و ویژگی‌های شاخص در رمان ابر اطلس اثر دیوید میچل بررسی کند. واژة روایت‌شناختیِ درون‌متنیت از اصول حاکم وحدت ارگانیک چارچوب‌های نظری مرتبط با بینامتنیت تأثیر گرفته است. پرسش‌های اصلی این پژوهش عبارت‌اند از: چیست مؤلفه‌های منحصر به‌فرد چه هستند؟ عناصر ساختاری معنایی سبب می‌شوند جنبه‌های بافت رواییِ مصداق داشته باشند؟ نقشی ایفا می‌کنند؟ م...

Many recent creationists are attracted to plasma astronomy, the idea that electromagnetic effects rather than gravity are responsible for much of the structure of the universe. I examine the claims of at least one proponent of plasma astronomy, Donald E. Scott. Scott has written a book that discusses many aspects of plasma astronomy. This book appears to be the most concise treatment of plasma ...

A new algorithm is proposed for the construction of BrezingWeng-like elliptic curves such that polynomials defining the CM discriminant are linear. Using this construction, new families of curves with variable discriminants and embedding degrees of k ∈ {8, 16, 20, 24}, which were not covered by Freeman, Scott, and Teske [9], are presented. Our result is useful for constructing elliptic curves w...
