Salem–Spencer sets are also called 3-AP-free sequences or progression-free sets. They have also been called non-averaging sets, [ 1 ] [ 2 ] but this term has also been used to denote a set of integers none of which can be obtained as the average of any subset of the other numbers. [ 3 ]
Each tube is a muscular hollow organ [3] that is on average between 10 and 14 cm (3.9 and 5.5 in) in length, with an external diameter of 1 cm (0.39 in). [4] It has four described parts: the intramural part, isthmus, ampulla, and infundibulum with associated fimbriae.

Further, ectopic pregnancy is a typical complication. [3] Surgical interventions can be done by laparotomy or laparoscopy. Non-infertile patients who suffer from severe chronic pain due to hydrosalpinx formation that is not relieved by pain management may consider surgical removal of the affected tubes ( salpingectomy ) or even a hysterectomy ...
Musicians playing the salpinx (trumpet) and the hydraulis (water organ). Terracotta figurine made in Alexandria, 1st century BC Greek warrior blowing a salpinx. A salpinx (/ ˈ s æ l p ɪ ŋ k s /; plural salpinges / s æ l ˈ p ɪ n dʒ iː z /; Greek σάλπιγξ) was a trumpet-like instrument of the ancient Greeks. [1]
Small finite examples: The three partially ordered sets on the left are trees (in blue); one branch of one of the trees is highlighted (in green). The partially ordered set on the right (in red) is not a tree because x 1 < x 3 and x 2 < x 3, but x 1 is not comparable to x 2 (dashed orange line).
For symmetric difference, the sets ( ) and () = ( ) are always disjoint. So these two sets are equal if and only if they are both equal to ∅ . {\displaystyle \varnothing .} Moreover, L ∖ ( M R ) = ∅ {\displaystyle L\,\setminus \,(M\,\triangle \,R)=\varnothing } if and only if L ∩ M ∩ R = ∅ and L ⊆ M ∪ R . {\displaystyle L\cap M ...
In this same graph, the maximal cliques are the sets {a, b} and {b, c}. A MIS is also a dominating set in the graph, and every dominating set that is independent must be maximal independent, so MISs are also called independent dominating sets. The top two P 3 graphs are maximal independent sets while the bottom two are independent sets, but not ...
