What is Oeis complex?
The OEIS complex comprises a combination of defects including omphalocele, exstrophy of the cloaca, imperforate anus, and spinal defects. It may represent the most severe manifestation of a spectrum of birth defects, the exstrophy-epispadias sequence.
What causes Oeis?
What is cloacal exstrophy (OEIS Syndrome)? Cloacal exstrophy, also known as OEIS Syndrome, occurs when a portion of the large intestine lies outside of the body, and on either side of it —and connected to it — are the two halves of the bladder.
What does Oeis stand for?
The On-Line Encyclopedia of Integer Sequences
The On-Line Encyclopedia of Integer Sequences (OEIS) is an online database of integer sequences. It was created and maintained by Neil Sloane while researching at AT Labs.
What is a cloacal exstrophy?
Cloacal exstrophy is a condition where some internal organs that are normally in the lower abdomen are exposed externally. In addition, some of these organs may not have developed correctly and the lower parts of the reproductive, urinary and intestinal tracts may not be completely formed.
How does OEIS work?
Q: What is the purpose of the OEIS? A: The main purpose is to allow mathematicians or other scientists to find out if some sequence that turns up in their research has ever been seen before. If it has, they may find that the problem they’re working on has already been solved, or partially solved, by someone else.
How do you use OEIS?
Most people use the OEIS to get information about a particular number sequence. If you are a new visitor, then you might ask the database if it can recognize your favorite sequence, if you have one. To do this, go to the main look-up page, enter the sequence, and click Search.
What abnormalities are associated with a bladder exstrophy?
In classic bladder exstrophy, most anomalies are related to defects of the abdominal wall, bladder, genitalia, pelvic bones, rectum and anus.
Which is more emergent omphalocele or gastroschisis?
Gastroschisis occurs more often than omphalocele. But both conditions are considered rare. The National Institutes of Health reports that about 2 to 6 out of 10,000 newborns in the United States are born with gastroschisis.
What is difference between epispadias and hypospadias?
In hypospadias, the urethra doesn’t fully develop and reach the penis tip. The urethra opening ends up in a different position along the bottom of the penis. In epispadias, the tube also doesn’t form correctly. The opening is on the top of the penis.
Which sequence is not found in OEIS?
8795, 9935, 11147, 11446, 11612, 11630 were the first integers not appearing in any OEIS sequence, 8267 and 9734 were the first integers lower than 10000 appearing only once, 7495, 8758 and 9820 appeared in 2 sequences.
How do I add a sequence to OEIS?
Edit the entry for an existing sequence in the OEIS To add to or make changes to an existing entry for a sequence, log in (if you haven’t already) and then visit that sequence’s web page. Next to the sequence data you will see a link named “edit,” which you can click to submit changes or additions.
How do you find an OEIS?
The OEIS search engine will convert numbers containing decimal points into digit sequences automatically, so you can type 3.14159 directly. To search for a single large number in the OEIS, try Google, because Google has searched all the . txt files in the OEIS, and so may do a better job than the OEIS search engine.
