Cold stress, a major abiotic factor, positively modulates the synthesis of artemisinin in Artemisia annua and influences biosynthesis other secondary metabolites. To elucidate changes metabolites under low-temperature conditions, we conducted dynamic transcriptomic metabolite quantification analyses A. leaves. The accumulation total organic carbon (TOC) leaves cold stress provided ample precursors for synthesis. Short-term exposure to low temperature induced transient increase jasmonic acid...

Multi-label active learning addresses the scarce labeled example problem by querying most valuable unlabeled examples, or example-label pairs, to achieve a better performance with limited query cost. Current multi-label methods require scrutiny of whole in order obtain its annotation. In contrast, one can find positive evidence respect label examining specific patterns (i.e., subexample), rather than example, thus making annotation process more efficient. Based on this observation, we...

Abstract Automatic colour‐patterned fabric‐defect detection is essential and challenging in controlling manufacturing quality. Because of the scarcity defective fabric samples imbalance defect types, an auto‐encoder trained with defect‐free used. However, sometimes has weak generalisation ability, leading to mis‐ or over‐detection defects. An unsupervised memorising method proposed for The designs a memory‐guided quantisation variational auto‐encoder‐2 model improves residual post‐processing...

Here we report a low-cost and "green" phosphine-free route for the size- shape-controlled synthesis of high-quality zinc blende (cubic) ZnSe nanocrystals. To avoid use expensive toxic solvents such as trioctylphosphine (TOP) or tributylphosphine (TBP), SeO2 was dispersed in 1-octadecene (ODE) chalcogen precursor. It has been found that temperature surface ligand influenced nucleation, reaction speed formation different shapes. Absorption spectroscopy, fluorescence powder X-ray diffraction...
