In the Collatz problem, certain runs of consecutive integers have the same height. This phenomenon is investigated using an algorithm for reconstructing the trajectory of a number from the parity vector of the number. It is found that pain of consecutive integers of the same height occur infinitely

The Collatz function C(n) is defined to take odd numbers n to 3n + 1 and even numbers n to n/2. This note presents computational results on consecutive numbers that have the same height and the same total stopping time by the Collatz function. A 35654-tuple of consecutive numbers was found. In consequence there exist infinitely many such 35654-tuples. A heuristic is given for estimating how long consecutive runs of the same height and the same total stopping time should be.

Let m(n) be the number of ordered factorizations of n 1 in factors larger than 1. We prove that for every Ξ΅ > 0 holds for all integers n > n 0 , while, for a suitable constant c > 0, holds for infinitely many positive integers n, where Ο = 1.72864 . . . is the positive real solution to ΞΆ(Ο) = 2.

The feasibility of using the same slide repeatedly for fluorescence in situ hybridization (FISH) experiments was systematically evaluated by applying standard procedures and various combinations of direct-and indirect-labeled probes to slides from patients with hematologic malignancies.
