Weather Extremes Shock Maize Production: Current Approaches and Future Research Directions in Africa

open access: yesPlants
Extreme weather events have led to widespread yield losses and significant global economic damage in recent decades. African agriculture is particularly vulnerable due to its harsh environments and limited adaptation capacity.

MIND THE GAP [PDF]

open access: yesInternational Journal of Modern Physics A, 2001
We discuss an optimisation criterion for the exact renormalisation group based on the inverse effective propagator, which displays a gap. We show that a simple extremisation of the gap stabilises the flow, leading to better convergence of approximate solutions towards the physical theory. This improves the reliability of truncations, most relevant for

The retouching on archaeological metal artifacts: reflections and proposals, between theory and practice

open access: yesGe-conservación, 2020
When the restoration of archaeological metal artifacts is considered, the reconstruction and chromatic treatment of the gaps often determine the correct reading of the object, by suggesting its original morphology and external coloring as linked to the ...

Surface Gap Solitons

open access: yesPhysical Review Letters, 2006
We put forward the existence of surface gap solitons at the interface between uniform media and an optical lattice with defocusing nonlinearity. Such new type of solitons forms when the incident and reflected waves at the interface of the lattice experience Bragg scattering, and feature a combination of the unique properties of both surface waves and ...

Gap-planar graphs

open access: yesTheoretical Computer Science, 2018
We introduce the family of $k$-gap-planar graphs for $k \geq 0$, i.e., graphs that have a drawing in which each crossing is assigned to one of the two involved edges and each edge is assigned at most $k$ of its crossings. This definition is motivated by applications in edge casing, as a $k$-gap-planar graph can be drawn crossing-free after introducing ...

Bench-to-bedside and bedside back to the bench; coordinating clinical and experimental traumatic brain injury studies

open access: yesFrontiers in Neurology, 2012
Traumatic brain injury is one of the leading cause of death and long term disability in virtually every country. Advances in neurointensive care have resulted in steadily decreasing morbidity, but the number of individuals with severe long term ...
