|Post-processing of the residuals is vital to obtain viable segmentations, since the compared methods yield residuals where notions of geometry and structure are not explicitly considered. Our chosen post-processing steps introduce very basic prior knowledge on size, shape and location of anomalies in...
yet still very workable. The Ultra setting is best planned for an overnight session but does yield somewhat better output. Results can come out a bit glitchy, which requires some experimenting with proper settings and algorithms. In the High preset, the shape is compiled completely and accuratel...
Finally, double-Tet-knockout embryos created with 6 sgRNAs showed reduced birth rate, and triple Tet-knockout embryos created by 9 sgRNAs yield- ed no live birth (Figure 3E), consistent with previous studies [13-16]. These results demonstrate the efficiency of one-step deletion of multiple...
The optimized condition produced ketone 2a with an isolated yield of 94% (entry 1). Methyl-substituted ketone 2b was obtained in a similarly high yield of 93% (entry 2). To investigate the electronic effect of substituents, electron-withdrawing 4-fluoro- and electron-donating 4-methoxy-...
Thus, there is a great need to develop a facile, low-cost, and high-yield method for the preparation of CDs with strong fluorescence emission. In this study, we employed citric acid and glutathione to produce CCA+GSH dots based on a one-step strategy (Fig. 1). In particular, CA ...
a high percentage of these substructures being correct. On the test data, even if products and associated candidates yield results that are inclusive of incorrect substructures, the average number of correct substructures is still 7.3. This indicates that, after aggregating the results, the model can...
