Summary: The impact of the ionization source in the ITER far SOL on the overall SOL performance has been numerically studied using SOLPS-ITER modeling. It has been found that this source can significantly affect the retention of the seeded impurity radiator (Ne) in the divertor and the plasma temperature in the far SOL. Both factors indicate the beneficial effect of high fuel throughput on separatrix and pedestal plasma composition.

Summary: By the end of 2019, ITER has completed about 67% of the overall work required to achieve First Plasma, with significant progress in key building completion and manufacturing. The project is on track to enter the Assembly Phase in 2020 and achieve First Plasma in 2025. The ITER Research Plan and systems installation are consistent with the planned timeline towards full fusion power operation in 2035.

Summary: Time-dependent SOLPS-ITER simulations were used to identify reduced models using the SINDy method and develop model-predictive control of the boundary plasma state. The identified reduced models show good predictive accuracy and can be applied to other time-dependent data from boundary simulations or experimental data.

Summary: Antimicrobial or antioxidant active packaging (AP) is a technology that incorporates a bioactive agent into packaging material to protect the contained product from deterioration. The goal of AP fabrication is to achieve a balance between the deterioration rate and controlled release of the bioactive agent. Modeling the controlled release can avoid trial and error and predict the release behavior of bioactive agents in different packaging systems. This review provides an overview of release controlling approaches, release mechanisms, different release profiles, and modeling techniques used in AP.

Summary: This study used advanced analytical tools to understand the kinetics of aromatic compounds during the fermentation process of kombucha and control its sensory profiles to make it a beverage with mass market appeal. The synthesis of various compounds by Saccharomyces genus and the terpene synthesis during fermentation were identified. Principal component analysis revealed the major variations in carboxylic acids, alcohols, and terpenes. Aromatic analysis identified 17 aroma-active compounds. The changes in VOCs led to different flavors, from citrus-floral-sweet notes to intense citrus-herbal-lavender-bergamot notes, and finally to sweet-floral-bready-honey notes. This study provides insights for the development of new drinks by controlling the fermentation process and optimizing their sensory profile, which could enhance consumer acceptance.
