Effects of Temperature and Light on the Germination-Promoting Activity by Melatonin in Almond Seeds without Stratification

open access: yesAgronomy, 2022
Melatonin is a new plant hormone involved in multiple physiological functions in plants. Its roles in germination, photosynthesis, growth, flowering, fruiting, and senescence are noteworthy.

Sheaf-Theoretic Stratification Learning from Geometric and Topological Perspectives [PDF]

open access: yes, 2020
In this paper, we investigate a sheaf-theoretic interpretation of stratification learning from geometric and topological perspectives. Our main result is the construction of stratification learning algorithms framed in terms of a sheaf on a partially ...

Computational Analysis for Bioconvection of Microorganisms in Prandtl Nanofluid Darcy–Forchheimer Flow across an Inclined Sheet

open access: yesNanomaterials, 2022
The two-dimensional boundary layer flow of a Prandtl nanofluid was explored in the presence of an aligned magnetic field over an inclined stretching/shrinking sheet in a non-Darcy permeable medium. To transform the PDEs of the leading equations into ODEs,

Cardiac risk stratification in stable coronary artery disease

open access: yesKlinicist, 2020
Despite a gradually decreased mortality from cardiovascular diseases, including coronary artery disease (CAD), they remain the main cause of death in the world. In the coming decades, an increased prevalence of CAD is expected.

Mesoscale variability of the Mexican Tropical Pacific using TOPEX and SeaWiFS data

open access: yesCiencias Marinas, 2006
The Mexican Tropical Pacific has oligotrophic characteristics; however, it sustains an abundant biodiversity, mainly because of upwelling promoted by its relatively shallow thermocline, strong winds and mesoscale eddies.

The Influence of Wind Direction during Storms on Sea Temperature in the Coastal Water of Muping, China

open access: yesJournal of Marine Science and Engineering, 2021
Sea temperature structures are important for water stratification and marine ecosystems. In the coastal water of Muping, China, stationary measurements of sea temperature captured temporal temperature changes during two summer storm events.
