Genetic progress in rice yield: preliminary insights from historically released varieties in Sub-Saharan Africa [PDF]

open access: yesFrontiers in Plant Science
Rice is a vital staple crop in sub-Saharan Africa (SSA), where improving grain yield is critical for food security and economic growth. Assessing genetic gain over time is essential for measuring breeding effectiveness and guiding future strategies and ...

Uniform dipole resonance and suppressed quadrupole resonance for constant transmittivity full phase control plasmonic metasurfaces [PDF]

open access: yesScientific Reports
Transmission-type plasmonic phase metasurfaces utilizing the Pancharatnam-Berry (PB) phase require constant transmittivity with complete phase variation from 0 to 2 $$\pi$$ .

Affine Subspace Concentration Conditions [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2023
We define a new notion of affine subspace concentration conditions for lattice polytopes, and prove that they hold for smooth and reflexive polytopes with barycenter at the origin.

Relations on a lattice of varieties of completely regular semigroups [PDF]

open access: yesMathematica Bohemica, 2020
Completely regular semigroups $\mathcal{CR}$ are considered here with the unary operation of inversion within the maximal subgroups of the semigroup. This makes $\mathcal{CR}$ a variety; its lattice of subvarieties is denoted by $\mathcal{L(CR)}$.

Constructive Canonicity of Inductive Inequalities [PDF]

open access: yesLogical Methods in Computer Science, 2020
We prove the canonicity of inductive inequalities in a constructive meta-theory, for classes of logics algebraically captured by varieties of normal and regular lattice expansions.

Varieties of K-lattices

open access: yesFuzzy Sets and Systems, 2022
In this paper we deal with varieties of commutative residuated lattices that arise from a specific kind of construction: the {\em twist-product} of a lattice. Twist-products were first considered by Kalman in 1958 to deal with order involutions on plain lattices, but the extension of this concept to residuated lattices has attracted some attention ...
