Yield, stability, and plasticity of Arabica coffee genotypes under contrasting pruning systems

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Coffee yield instability caused by biennial bearing causes coffee yield instability, reducing production predictability and farm income. Biennial drastic pruning (Zero Crop), which alternates harvest and no‐harvest years, has been proposed to reduce this instability, but its benefits depend on genotype performance under contrasting management.

Genetic progress from 15 years of white oat breeding in Brazil

Crop Science, Volume 66, Issue 3, May/June 2026.
Abstract Despite advances in crop management and breeding, cereals still face considerable yield losses from phytopathogens and lodging caused by adverse weather. Developing oat genotypes that combine disease tolerance, lodging resistance, and industrial quality is therefore essential, and the estimation of genetic progress allows validation of ...

Dephasing in semiconductor-superconductor structures by coupling to a voltage probe

, 2000
We study dephasing in semiconductor-superconductor structures caused by coupling to a voltage probe. We consider structures where the semiconductor consists of two scattering regions between which partial dephasing is possible. As a particular example we

Geometry of Supergravity and the Batalin–Vilkovisky Formulation of the N=1$\mathcal N=1$ Theory in Ten Dimensions

Fortschritte der Physik, Volume 74, Issue 5, May 2026.
ABSTRACT We provide full details of a BV formulation of N=1$\mathcal N=1$ supergravity in 10 dimensions, to all orders in fermions, built from the generalised geometry description of the theory. In contrast to standard treatments, we introduce neither the degrees of freedom corresponding to orthonormal frames for the metric nor the local Lorentz ...

A combinatorial interpretation for Schreyer's tetragonal invariants [PDF]

, 2014
Schreyer has proved that the graded Betti numbers of a canonical tetragonal curve are determined by two integers b(1) and b(2), associated to the curve through a certain geometric construction.

Spinor Field Realizations of the half-integer $W_{2,s}$ Strings

, 2008
The grading Becchi-Rouet-Stora-Tyutin (BRST) method gives a way to construct the integer $W_{2,s}$ strings, where the BRST charge is written as $Q_B=Q_0+Q_1$.
