The survival of animals depends, among other things, on their ability to identify threats in their surrounding environment. Senses such as olfaction, vision and taste play an essential role in sampling their living environment, including microorganisms,

Thereafter, neutrophils were left untreated (‘no stimulus’) or stimulated with PR3-ANCA (200 μg/ml) or PMA (100 ng/ml). Results are mean±s.e.m. superoxide release in nmol/105 cells/45 min from eight separate experiments. * P<0.05 compared to TNFα-primed, uninhibited ...
Update 1: The conjectureIf has been proved for the special case $x+y$ (in the answer below) and is already known to be true for $x^2 + y^2$. Experimental data shows that $x^3 + y^3$ is not divisible by infinitely many primes of the form $8k+3$ while $x^4 + y^4$ is ...

Like (12) Solve Later Add To Group Did you know that the number 5 is the first safe prime? A safe prime is a prime number that can be expressed as 2p+1, where p is also a prime. To celebrate Cody's Five-Year Anniversary, write a function to determine if a positive integer n ...
Under this definition, if n is a pseudoprime to base a, then n and a are necessarily coprime ( HINT: un + va = 1, for some integers u and v). There's also a weaker definition of the term for which this need not be so. Carmichael...
Add To Group Given an even whole numbern(> 2), return a 2-element vector of primes,p, such thatp(1) + p(2) = n. The elements ofpshould be in increasing numerical order (that is,p(1) <=p(2)). Fun note: technically it cannot be guaranteed that such primes exist for anyn....
