The Biosynthesis of Astaxanthin Esters in sp. is Mediated by a Bifunctional Diacylglycerol Acyltransferase.

Astaxanthin esters are a major form of astaxanthin found in nature. However, the exact mechanisms of the biosynthesis and storage of astaxanthin esters were previously unknown. We found that sp.

AHEGC: Adaptive Hindsight Experience Replay With Goal-Amended Curiosity Module for Robot Control.

With shaped reward functions, reinforcement learning (RL) has recently been successfully applied to several robot control tasks. However, designing a task-relevant and well-performing reward function takes time and effort. Still, if RL can train an agent to complete a task in a sparse reward environment, it is an effective way to address the difficulty of reward function design, but it is still a significant challenge.

Modulating DHA-Producing sp. toward Astaxanthin Biosynthesis via a Seamless Genome Editing System.

sp. is commercially used for the production of docosahexaenoic acid (DHA). Some strains of sp.

Raman mapping of piezoelectric poly(l-lactic acid) films for force sensors.

Poly-l-lactic acid (PLLA) is a synthetic, biocompatible, biodegradable polymer with good piezoelectric properties. The prepared PLLA films were annealed in the oven at 140 °C for 0 h, 3 h, 12 h, and 24 h, respectively. The influences of temperature treatment time on the optoelectronic properties of the PLLA films and piezoelectric sensors based on them were investigated.

Spectroscopy and Theoretical Modeling of Phonon Vibration Modes and Band Gap Energy of CuZnSn(S Se ) Bulk Crystals and Thin Films.

Semiconductor CuZnSn(S Se ) (CZTSSe) solid solution is considered as a perspective absorber material for solar cells. However, during its synthesis or deposition, any modification in the resulting optical properties is hardly predicted. In this study, experimental and theoretical analyses of CZTSSe bulk crystals and thin films are presented based on Raman scattering and absorption spectroscopies together with compositional and morphological characterizations.

Lipid Distribution Pattern and Transcriptomic Insights Revealed the Potential Mechanism of Docosahexaenoic Acid Traffics in sp. A-2.

sp. A-2 is a heterotrophic marine fungus used for the commercial production of docosahexaenoic acid (DHA). However, the pattern of the distribution of DHA and how DHA is channeled into phospholipid (PL) and triacylglycerol (TAG) are unknown.
