Process for optimizing cobalt electrofill using sacrificial oxidants
Embodiments herein relate to methods, apparatus, and systems for electroplating metal into recessed features using a superconformal fill mechanism that provides relatively faster plating within a feature and relatively slower plating in the field region. Moreover, within the feature, plating occurs faster toward the bottom of the feature compared to the top of the feature. The result is that the feature is filled with metal from the bottom upwards, resulting in a high quality fill without the formation of seams or voids, defects that are likely where a conformal fill mechanism is used. The superconformal fill mechanism relies on the presence of a sacrificial oxidant molecule that is used to develop a differential current efficiency within the feature compared to the field region. Various plating conditions are balanced against one another to ensure that the feature fills from the bottom upwards. No organic plating additives are necessary, though plating additives can be used to improve the process. |

Taurine production or increased levels of hypoataurine or taurine in plants could be used as nutraceutical, pharmaceutical, or therapeutic compounds or as a supplement in animal feed or for animal feed or as an enhancer for plant growth or yield. |

Brassica GAT event and compositions and methods for the identification and/or detection thereof
Compositions and methods related to transgenic glyphosate tolerant Brassica plants are provided. Specifically, the present invention provides Brassica plants having a DP-073496-4 event which imparts tolerance to glyphosate. The Brassica plant harboring the DP-073496-4 event at the recited chromosomal location comprises genomic/transgene junctions within SEQ ID NO: 2 or with genomic/transgene junctions as set forth in SEQ ID NO: 12 and/or 13. The characterization of the genomic insertion site of the event provides for an enhanced breeding efficiency and enables the use of molecular markers to track the transgene insert in the breeding populations and progeny thereof. Various methods and compositions for the identification, detection, and use of the event are provided. |

Synthetic nucleic acid spike-ins
This disclosure provides methods for determining relative abundance of one or more non-host species in a sample from a host. Also provided are methods involving addition of known concentrations of synthetic nucleic acids to a sample and performing sequencing assays to identify non-host species such as pathogens. Also provided are methods of tracking samples, tracking reagents, and tracking diversity loss in sequencing assays. |

Deepsimulator method and system for mimicking nanopore sequencing
A method for sequencing biopolymers. The method includes selecting with a sequence generator module an input nucleotide sequence having plural k-mers; simulating with a deep learning simulator, actual electrical current signals corresponding to the input nucleotide sequence; identifying reads that correspond to the actual electrical current signals; and displaying the reads. The deep learning simulator includes a context-dependent deep learning model that takes into consideration a position of a k-mer of the plural k-mers on the input nucleotide sequence when calculating a corresponding actual electrical current. |

Polyphenolic additives in sequencing by synthesis
The invention relates to methods, compositions, devices, systems and kits as described including, without limitation, reagents and mixtures for determining the identity of nucleic acids in nucleotide sequences using, for example, sequencing by synthesis methods. In particular, the present invention contemplates the use of polyphenolic compounds, known as antioxidant additives, to improve the efficiency of Sequencing-By-Synthesis reactions. For example, gallic acid (GA) is shown herein to be one of many exemplary SBS polyphenolic additives. |
