Coxiella burnetii is the causative agent of the zoonotic disease Q fever. To date, the lipopolysaccharide (LPS) is the only defined and characterized virulence determinant of C. burnetii. In this study, proteome profiles ...

The k-generalized Fibonacci sequence (Fn(k))n (sometimes also called k-bonacci or k-step Fibonacci sequence), with k >= 2, is defined by the values 0,0, horizontal ellipsis ,0,1 of starting k its terms and such way that ...

In this paper, we study the Diophantine equation $u_n=R(m)P(m)^{Q(m)}$,where $R, P$ and $Q$ are some polynomials (under weak assumptions) and $u_n$ is a Lucas sequence, thus the sequence $(u_n)_{n\geq 0}$ with characteristic ...

The elementary symmetric functions played a crucial role in the study of zeros of non-zero polynomials in $C[x]$, and the problem of finding zeros in $Q[x]$ leads to the definition of algebraic and transcendental numbers. ...
