Abstract Cytokinins (CKs) play a fundamental role in regulating dynamics of organ source/sink relationships during plant development, including flowering and seed formation stages. As result, CKs are key drivers yield. The cytokinin oxidase/dehydrogenase (CKX) is one the critical enzymes responsible for CK levels by causing their irreversible degradation. Variation CKX activity significantly correlated with yield many crop species while soybean ( Glycine max L.), possible associations...

Abstract Fatty acid (FA) levels and profiles are vital for soybean oil quality, while cytokinins (CKs) abscisic (ABA) potent regulators of plant growth development. Previous research suggested associations between FA biosynthesis hormonal signalling networks; however, regulation accumulation during ( Glycine max ) seed maturation has never been measured. We analysed hormone obtained from HPLC-(ESI)-MS/MS GC-FID screening maturation. A multilayered data processing approach, involving...

In this article, we deal with some computational aspects of geodesic convex sets. Motzkin-type theorem, Radon-type and Helly-type theorem for sets are shown. particular, given a finite collection in simple polygon an “oracle,” which accepts as input three the gives its output intersection point or reports nonexistence; present algorithm finding collection.

We consider class of equilibrium models including the implicit Walras supply-demand and competitive models. Such a model in this class, general, is ill-posed. formulate such form variational inequality having certain monotonicity property which allow us to describe regularization algorithm avoiding ill-posedness based upon bilevel optimization for fnding point that nearest given guessed or desired price model. The obtained computational results with many randomly generated data show proposed...

Given γ>0, a real-valued function f defined on noempty convex set D of normed space X is said to be symmetrically γ-convex iff for all x oand 1∊D satisfying , the Jensen inequality fulfilled and . Though only required hold true at two points segment [x 0,x 1] such has interesting properties similar those classical functions. For instance, from finite-dimensional locally Lipschitzian each γ-interior point D, i.e., x∊D which there some ε>0 that implies This other this class are established in our paper

Solving shortest path problems inside simple polygons is a very classical problem in motion planning. To date, it has usually relied on triangulation of the polygons. The question: "Can one devise O(n) time algorithm for computing between two points polygon (with n vertices), without resorting to (complicated) linear-time algorithm?" raised by J. S. B. Mitchell Handbook Computational Geometry (J. Sack and Urrutia, eds., Elsevier Science B.V., 2000), still open. aim this paper show that...

Abstract For some given positive δ, a function f : D ⊆ X → ℝ is called δ-convex if it satisfies the Jensen inequality f(x λ) := (1 − λ)f(x 0) + λf(x 1) for all x 0, 1 ∈ and λ ≔ λ)x 0 λx [x 1] satisfying ‖x 1‖ ≥ 0‖ δ/2 [Hu, T.
