The generation of various β-chiral sulfones bearing chiral cyclic sulfinamides through photoredox-catalyzed sulfur dioxide insertion with asymmetric radical cyclization is described. This method features a broad substrate scope and excellent stereospecificity. Computational studies reveal that the dispersion interaction between sulfinyl group and CH2SO2Ph group plays a crucial role in the stereoselectivity control.

通过田间试验研究了绿洲膜下滴灌调亏马铃薯各生育期耗水规律及其影响因素,建立了以Jensen模型为基础的水分生产函数并对马铃薯灌溉制度进行了优化。结果表明:块茎膨大期马铃薯水分敏感指数最大,块茎形成期次之,苗期和淀粉积累期较小;块茎形成期轻度调亏对马铃薯产量无显著影响(P>0.05),而块茎形成期中度调亏、块茎膨大期轻度和中度调亏对其产量均有显著影响(P<0.05);块茎形成期轻度调亏的水分利用效率比块茎形成期中度调亏、块茎膨大期轻度调亏和全生育期充分灌水分别提高了6.2%、8.3%和6.7%;膜下滴灌调亏马铃薯产量随耗水量增加而增加,水分利用效率随之降低,全生育期充分灌水比块茎膨大期中度水分调亏耗水量增加22.4%,产量增加20.4%,水分利用效率降低14.0%。采用遗传算法并结合水分生产函数进行灌溉制度优化,结果表明:河西绿洲区膜下滴灌马铃薯全生育期灌溉定额为225 mm时,产量最高,为43.86 t·hm-2,灌溉水利用效率为19.5 kg·m-2;灌溉制度为苗期灌水20~30 mm,块茎形成期灌水70~75 mm,块茎膨大期灌水100~115mm,淀粉积累期灌水20~25 mm,灌水间隔为7 d。因此,膜下滴灌调亏在降低马铃薯耗水量的同时,提高了水分利用效率,在块茎形成期轻度水分调亏不影响产量,可达到节水增产的目的。

We rethink the segment anything model(SAM) and propose a novel multiprompt network called COMPrompter for camouflaged object detection(COD). SAM has zero-shot generalization ability beyond other models and can provide an ideal framework for COD. Our network aims to enhance the single prompt strategy in SAM to a multiprompt strategy. To achieve this, we propose an edge gradient extraction module, which generates a mask containing gradient information regarding the boundaries of camouflaged objects. This gradient mask is then used as a novel boundary prompt, enhancing the segmentation process. Thereafter, we design a box-boundary mutual guidance module, which fosters more precise and comprehensive feature extraction via mutual guidance between a boundary prompt and a box prompt. This collaboration enhances the model's ability to accurately detect camouflaged objects. Moreover, we employ the discrete wavelet transform to extract high-frequency features from image embeddings. The high-frequency features serve as a supplementary component to the multiprompt ***, our COMPrompter guides the network to achieve enhanced segmentation results, thereby advancing the development of SAM in terms of COD. Experimental results across COD benchmarks demonstrate that COMPrompter achieves a cutting-edge performance, surpassing the current leading model by an average positive metric of 2.2% in COD10K. In the specific application of COD, the experimental results in polyp segmentation show that our model is superior to top-tier methods as well. The code will be made available at https://***/guobaoxiao/COMPrompter.
