Rapid validation of newly predicted materials through autonomous synthesis requires real-time adaptive control methods that exploit physics knowledge, a capability that is lacking in most systems. Here, we demonstrate an approach to enable real-time control of thin film synthesis by combining optical diagnostics with a Bayesian state estimation method. We developed a physical model for film growth and applied the direct filter (DF) method for real-time estimation of nucleation and growth rates during pulsed laser deposition (PLD).

Plants are colonized by a vast array of microorganisms that outstrip plant cell densities and genes, thus referred to as plant's second genome or extended genome. The microbial communities exert a significant influence on the vigor, growth, development and productivity of plants by supporting nutrient acquisition, organic matter decomposition and tolerance against biotic and abiotic stresses such as heat, high salt, drought and disease, by regulating plant defense responses. The rhizosphere is a complex micro-ecological zone in the direct vicinity of plant roots and is considered a hotspot of microbial diversity.

Pharmacological elevation of cyclic AMP (cAMP) of cultured cumulus-oocyte complexes (COC) before or coincident with initiation of maturation has been reported to improve outcomes for various systems for in vitro production of embryos. Here it was hypothesized that artificial elevation of cAMP in the oocyte for a 2-h period of prematuration would improve developmental competence of matured oocytes and result in increased blastocyst yield and altered expression of genes important for embryonic differentiation. Treated COC were cultured for 2 h with dibutyryl cAMP (dbcAMP), a membrane-permeable form of cAMP, and 3-isobutyl-1-methylxanthine (IBMX), which inhibits phosphodiesterases that convert cAMP to ATP.

Environmental conditions influence the maternal deposition of hormones into eggs, which is hypothesized to adaptively modify developmental outcomes in offspring. However, most ecosystems harbour environmental contaminants capable of disrupting endocrine signaling, and maternal exposure to these compounds has the potential to further alter offspring traits. Studies rarely examine maternally derived hormones and contaminants along with offspring phenotypes, and we know little about their interrelationships and potential interactions.
