Automatic load-balancing techniques in a network device are used to select, from a multipath group, a path to assign to a flow based on observed state attributes such as path state(s), device state(s), port state(s), or queue state(s) of the paths.

However, if the flow(s) go idle, or if the mapped path fails, a new optimal path may be assigned to the flow(s) from the multipath group. |

Method and apparatus for decoding polar code in communication and broadcasting system
The disclosure proposes a technique for achieving validity decision performance of a suitable level in communication and broadcasting systems using a polar code. The polar code is a channel code in which it is difficult to use a syndrome check due to a successive cancellation (SC)-based decoding operation and coding structure. Accordingly, in the communication of the related art and broadcasting systems using the polar code, a validity check of a decoding result has been performed by using a path-metric (PM) generated during decoding and a concatenated error detection code, such as a cyclic redundancy check (CRC) code. However, it is difficult to achieve target error detection performance only via such methods when the length of the CRC code is short or when input and output lengths of a code are short. In this regard, an embodiment of the disclosure proposes a method for obtaining a Euclidean distance-based metric between a received signal and a decoded signal by using an estimated codeword output bit sequence, and performing post error detection based on this. |

Methods are provided for planarizing a patterned substrate in a spatial atomic layer processing system comprising a rotating platen.

Method of using genetic architecture of phenomic-enabled canopy coverage in Glycine max
Digital imagery can help to quantify seasonal changes in desirable crop phenotypes that can be treated as quantitative traits. Because limitations in precise and functional phenotyping restrain genetic improvement in the post-genomic era, imagery-based phenomics could become the next breakthrough to accelerate genetic gains in field crops. Whereas many phenomic studies focus on exploratory analysis of spectral data without obvious interpretative value, we used field images to directly measure soybean canopy development from phenological stage V2 to R5. Over three years, we collected imagery using ground and aerial platforms of a large and diverse nested association panel comprising 5,555 lines. Genome-wide association analysis of canopy coverage across sampling dates detected a large quantitative trait locus on soybean (Glycine max, L. Merr.) chromosome 19. This QTL provided an increase in yield of 47.3 kg·ha−1. Variance component analysis indicated that a parameter, described as average canopy coverage, is a highly heritable trait (h2=0.77) with a promising genetic correlation with grain yield (0.87), enabling indirect selection of yield via canopy development parameters. Our findings indicate that fast canopy coverage is an early season trait that is inexpensive to measure and has great potential for application in breeding programs focused on yield improvement. We recommend using the average canopy coverage in multiple trait schemes, especially for the early stages of the breeding pipeline (including progeny rows and preliminary yield trials), in which the large number of field plots makes collection of grain yield data challenging. |
