Estimating ammonium changes in pilot and full-scale constructed wetlands using kinetic model, linear regression, and machine learning.

Constructed wetlands (CWs) are a widely utilized nature-based wastewater treatment method for various effluents. However, their application has been more focused on pilot and full-scale CWs with substantial surface areas and extended operation times, which hold greater relevance in practical scenarios. This study used kinetics, linear regression (LR), and machine learning (ML) models to estimate effluent ammonium in pilot and full-scale CWs.

Selective egg cell polyspermy bypasses the triploid block.

Polyploidization, the increase in genome copies, is considered a major driving force for speciation. We have recently provided the first direct in planta evidence for polyspermy induced polyploidization. Capitalizing on a novel -based polyspermy assay, we here show that polyspermy can selectively polyploidize the egg cell, while rendering the genome size of the ploidy-sensitive central cell unaffected.

Antenatal influenza and pertussis vaccination in Western Australia: a cross-sectional survey of vaccine uptake and influencing factors.

Background: Influenza and pertussis vaccines have been recommended in Australia for women during each pregnancy since 2010 and 2015, respectively. Estimating vaccination coverage and identifying factors affecting uptake are important for improving antenatal immunisation services.

Methods: A random sample of 800 Western Australian women ≥18 years of age who gave birth between 4th April and 4th October 2015 were selected.

Publisher Correction: Triparental plants provide direct evidence for polyspermy induced polyploidy.

This Article contained errors in Fig. 3 that were brought to our attention by the authors during the production process but, inadvertently, were not corrected before publication. The tick marks on the y-axis in panels b, f, and k, and the median line in the box-and-whisker plot for biparental diploid plants (BP) in panel i were shifted downwards by up to 2 mm.

Triparental plants provide direct evidence for polyspermy induced polyploidy.

It is considered an inviolable principle that sexually reproducing organisms have no more than two parents and fertilization of an egg by multiple sperm (polyspermy) is lethal in many eukaryotes. In flowering plants polyspermy has remained a hypothetical concept, due to the lack of tools to unambiguously identify and trace this event. We established a high-throughput polyspermy detection assay, which uncovered that supernumerary sperm fusion does occur in planta and can generate viable polyploid offspring.
