Due to the summation (integration) from to, linear trends in the mean of the profile represent constant trends in the initial sequence, and DFA1 only removes such constant trends (steps) in the. In general DFA of order removes (polynomial) trends of order. For linear trends in the mean of at least DFA2 is needed.
A few days after I had a severe outbreak of canker sores I developed a swollen lymph node under my chin, right in the middle. I went to the dr's after 2 days and he put me on antibiotics. I am trying to figure out how serious this swollen lymph node may be. It is about the size of a pea. It is not as painful as it was.
Diet - A diet lacking in vitamin B-12, zinc, folate (folic acid) or iron puts you at high risk of developing a canker sore. Likewise, certain foods such as chocolate, coffee, strawberries, eggs, nuts, cheese and highly acidic foods, such as pineapple can increase the likelihood of a canker sore outbreak.
