Patient discussion about differential

Q. How do you differentiate between fluorosis and caries? Both appear as white spots on the teeth, so clinically how do you differentiate between them? I know it has something to do with their appearance while wet and dry, but I am not sure what? please help me I can't find this in any book.

A. Only mild fluorosis is seen as white stop lesion on the tooth. It usually comes with brown spots. Look for them. Another method is trying to stick a dental explorer into it (not the Microsoft one- it’ll only be a portal for viruses..) and because caries is demineralized area it will feel kind of sticky. But I wouldn’t do that…it can harm the teeth. Another way is by an x ray. Fluorosis- you will see it as a whiter spot. Caries- a more translucent spot.

Q. Differentiate Wheezing & Asthma My sister who is 29 years old is suffering from wheezing for the past 7 years. Its not a genetic problem. Some times she uses inhaler for temporary recovery. She tried English medicine, homeo and other treatments. Is it an Asthma? I find very difficult in seeing her struggle when she find hard to breathe. Please help to make her free out of this struggle.

A. i see what scares you...it's frustrating to see your loved ones suffer and you cannot help. if she is has an inhaler- that mean she has been to the Dr. and he prescribed her some kind of medicine. without giving a diagnose first...?

Q. how can i differentiate between normal stomach ache and an Appendicitis? I've been having a strange sharp pain in my stomach lately and a friend of mine told me it could be Appendicitis.

A. When you have Appendicitis, there should be a sharp pain on the right lower Abdomen. but you mustn't forget that Appendicitis is an inflammation. which means you'll have a fever some time in the near future, and it always get worse. not like other Abdominal pains. you'll vomit probably. i had my Appendix removed 2 years ago. don't worry, it's not too bad ;).

If one line in a differential pair sees a higher or lower effective Dk than the other, there will be skew in the propagation delay between the two lines.
Differential skew, or simply "skew," is typically measured in picoseconds (ps).
As a result, we show that, unless considering the details of the S-boxes, there is no impossible differential path more than or equal to 3-round, 5-round, 7-round and 9-round impossible differentials for Kuznyechik[15], KLEIN[16] [17], Midori64[18] and MIBS[19] [20] respectively.
Section 2 describes some notations used in this paper such as SPN structure, Feistel structure, the matrix of linear transformation and impossible differentials. Section 3 presents the impossible differentials cryptanalysis of the SPN structure and proves the upper bound of the longest impossible differential paths of Kuznyechik, KLEIN and Midori64.
Now, we represent the main theorem of this study, through which a weakly singular Volterra integral equation can be expressed as a series of fractional differential transform for
We present a new set of notations for impossible differential analysis in Section 2.
Therefore, it is possible to describe and propose so-called pseudo-differential structures, which have differential input and output voltage terminals, however, the inner circuit topology is non-differential.

The present study is aimed to resolve the coupled problem of symmetric regularized long wave equations by the reduced differential transform method.
Many problems in natural and engineering sciences are modeled by Partial differential equations (PDE's).
In addition to total lengths, it is best to keep differential signals tightly "in phase" with one another.
