On Endomorphism Universality of Sparse Graph Classes

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT We show that every commutative idempotent monoid (a.k.a. lattice) is the endomorphism monoid of a subcubic graph. This solves a problem of Babai and Pultr and the degree bound is best‐possible. On the other hand, we show that no class excluding a minor can have all commutative idempotent monoids among its endomorphism monoids. As a by‐product,

Borax Promotes Fertility of Brassica napus Better Than Other Boron Species at Suboptimal Supply

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Continuous and sufficient boron (B) supply is essential for achieving maximum yield in Brassica napus. Increasing incidences of environmental water limitation are linked to reduced plant B availability and increased B deficiencies.
