Healing powers of dressing well
consistent value beyond the order of the authors. To quantify their utility and perceived value, Sauermann and Haeussler used data from more than 12,000 author contribution statements and surveyed 6000 corresponding authors. Author order correlated strongly with the breadth and type of author contribution, and most researchers, especially those at junior levels, saw value in the statements. How...
متن کاملEndosymbiosis: The Remarkable Healing Powers of Wolbachia
Wolbachia, a maternally transmitted bacterium globally present in arthropods, favors its own transmission by producing dramatic changes in host reproduction. Insight into the underlying molecular and cellular mechanisms comes from the identification of the Wolbachia effector protein TomO, which maintains host germline stem cells in an undifferentiated state.
متن کاملComparing Powers and Symbolic Powers of Ideals
We develop tools to study the problem of containment of symbolic powers I(m) in powers I for a homogeneous ideal I in a polynomial ring k[P ] in N + 1 variables over an arbitrary algebraically closed field k. We obtain results on the structure of the set of pairs (r, m) such that I(m) ⊆ I. As corollaries, we show that I2 contains I(3) whenever S is a finite generic set of points in P2 (thereby ...
متن کاملPowers of Two Modulo Powers of Three
Since 2 is a primitive root of 3 for each positive integer m, the set of points {(n, 2 mod 3) : n > 0}, viewed as a subset of Z>0×Z>0 is bi-periodic, with minimal periods φ(3) (horizontally) and 3 (vertically). We show that if one considers the classes of n modulo 6, one obtains a finer structural classification. This result is presented within the context of the question of strong normality of...
متن کاملDomination number of graph fractional powers
For any $k in mathbb{N}$, the $k$-subdivision of graph $G$ is a simple graph $G^{frac{1}{k}}$, which is constructed by replacing each edge of $G$ with a path of length $k$. In [Moharram N. Iradmusa, On colorings of graph fractional powers, Discrete Math., (310) 2010, No. 10-11, 1551-1556] the $m$th power of the $n$-subdivision of $G$ has been introduced as a fractional power of $G$, denoted by ...
