Infection Patterns of a Liberibacter Associated with Macrohomotoma gladiata, a Psyllid Feeding on Ficus microcarpa

open access: yesMicrobiology Spectrum, 2022
Almost all known Liberibacters can be transmitted by psyllids. This suggests that there is a coevolutionary relationship between these two groups of organisms. However, detailed investigation of Liberibacters and psyllids have often focused on only a few

The Distribution of Patterns in Random Trees [PDF]

open access: yesCombinatorics, Probability and Computing, 2008
Let$\Tn{}$denote the set of unrooted labelled trees of sizenand let ℳ be a particular (finite, unlabelled) tree. Assuming that every tree of$\Tn{}$is equally likely, it is shown that the limiting distribution asngoes to infinity of the number of occurrences of ℳ is asymptotically normal with mean value and variance asymptotically equivalent toμnand σ2n,

Wetting Pattern of Cow Urine Patch in an Andisol Assessed through Bromide Concentration Distribution: A Pilot Study [PDF]

open access: yes, 2022
Cow urine is a rich source of mobile nutrients such as nitrate (NO3−) and potassium (K+). The aim of this experiment was to evaluate the wetting pattern distribution through soil profile of cow urine patch in an andisol.
