Deep reinforcement learning and fuzzy logic controller codesign for energy management of hydrogen fuel cell powered electric vehicles.

Hydrogen-based electric vehicles such as Fuel Cell Electric Vehicles (FCHEVs) play an important role in producing zero carbon emissions and in reducing the pressure from the fuel economy crisis, simultaneously. This paper aims to address the energy management design for various performance metrics, such as power tracking and system accuracy, fuel cell lifetime, battery lifetime, and reduction of transient and peak current on Polymer Electrolyte Membrane Fuel Cell (PEMFC) and Li-ion batteries. The proposed algorithm includes a combination of reinforcement learning algorithms in low-level control loops and high-level supervisory control based on fuzzy logic load sharing, which is implemented in the system under consideration.

Efficient multi-allelic genome editing via CRISPR-Cas9 ribonucleoprotein-based delivery to mesophyll protoplasts.

Canola ( L.) is a valuable oilseed crop worldwide. However, trait improvement by breeding has been limited by its low genetic diversity and polyploid genetics.

Female zebrafish are more affected than males under polystyrene microplastics exposure.

Microplastics are ubiquitous in freshwater and can be absorbed into fish skin and gills, accumulate in the gut, and be transported to other tissues, thus posing a risk to fish health. Further studies are needed, however, to investigate effects such as endocrine disruption and multi-tissue toxicity. In this study, zebrafish were exposed to polystyrene (PS) microplastics and health-related indicators were measured, including skin mucus, gut damage, oxidative stress, stable isotope composition and reproduction as well as an assessment of changes to metabolites using a metabolomics approach.

Toxicological impacts of plastic microfibers from face masks on Artemia salina: An environmental assessment using Box-Behnken design.

An increase in global plastic manufacturing and subsequent disposal has resulted in widespread increase in microplastic pollution. Particularly, the post-COVID surge in face mask usage has introduced significant volumes of synthetic plastic microfibers into the environment, posing new ecological risks. Present study examines the toxicological impacts of face mask derived microfibers on Artemia salina, a key marine zooplankton species, using the Box-Behnken design to assess the effects of microfiber dosage (0.
