Non-uniform image deblurring is an ill-posed problem. Previous research efforts attempt to solve this problem by increasing the number of scales processed in the model, including but not limited to multi-scale methods, multi-patch methods, and atrous convolution. However, these methods are still subject to the fixed geometric structures, which are inherently unable to adequately handle complex blur. This paper proposes a novel residual block called Deform-ResBlock that is composed of traditional convolution and deformable convolution to enhance the model's capability of modeling geometric transformations. Then, we design parallel multi-scale convolution streams composed of densely Deform-ResBlock for extracting multi-scale features. Finally, we apply the multi-patch approach stacking two stages to deblur images gradually. The overall method is named deformable multi-scale fusion network (DMSFN). Compared to the previous methods, our method combines the advantages of multi-scale and multi-patch approaches and has better modeling geometric transformation capability. Extensive experimental results on the GoPro, HIDE, and RealBlur datasets demonstrate that the proposed method performs favorably against the state-of-the-art in the non-uniform image deblurring.

Symbiotic nitrogen fixation is the main source of nitrogen for soybean growth. Since the genotypes of rhizobia and soybean germplasms vary, the nitrogen-fixing ability of soybean after inoculation also varies. A few studies have reported that quantitative trait loci (QTLs) control biological nitrogen fixation traits, even soybean which is an important crop. The present study reported that the Sinorhizobium fredii HH103 gene rhcJ belongs to the tts (type III secretion) cluster and that the mutant HH103ΩrhcJ can clearly decrease the number of nodules in American soybeans. However, few QTLs of nodule traits have been identified. This study used a soybean (Glycine max (L.) Merr.) 'Charleston' × 'Dongnong 594' (C × D, n = 150) recombinant inbred line (RIL). Nodule traits were analysed in the RIL population after inoculation with S. fredii HH103 and the mutant HH103ΩrhcJ. Plants were grown in a greenhouse with a 16-h light cycle at 26 °C and an 8-h dark cycle at 18 °C. Then, 4 weeks after inoculation, plants were harvested for evaluation of nodule traits. Through QTL mapping, 16 QTLs were detected on 8 chromosomes. Quantitative PCR (qRT-PCR) and RNA-seq analysis determined that the genes Glyma.04g060600, Glyma.18g159800 and Glyma.13g252600 might interact with rhcJ. [ABSTRACT FROM AUTHOR]
