In the realm of nonlinear integrable systems, the presence of decompositions facilitates the establishment of linear superposition solutions and the derivation of novel coupled systems exhibiting nonlinear integrability. By focusing on single-component decompositions within the potential BKP hierarchy, it has been observed that specific linear superpositions of decomposition solutions remain consistent with the underlying equations. Moreover, through the implementation of multi-component decompositions within the potential BKP hierarchy,successful endeavors have been undertaken to formulate linear superposition solutions and novel coupled Kd V-type systems that resist decoupling via alterations in dependent variables.

目的探讨表观扩散系数(ADC)值在宫颈癌评估中的潜在价值。方法共112例宫颈癌病人及67例正常对照者在治疗前行常规3.0TMR成像及扩散加权成像(DWI)。所有ADC值分别用b=0,600s/mm2和b=0,1000s/mm2进行计算。结果两组ADC图均显示子宫颈癌的ADC值显著低于正常宫颈。高/中分化(G1/2)和低分化(G3)肿瘤的ADC值之间、鳞状细胞癌和腺癌的ADC值之间、根治性子宫切除术后复发或转移和术后无瘤生存者的术前ADC之间差异均有统计学意义。当子宫颈癌按其他特征(FIGO、淋巴结是否转移、肿瘤大小和年龄段)进行分组时,两组ADC图差异均无统计学意义。结论 ADC值在子宫颈癌和正常宫颈的鉴别诊断中有很高的诊断准确率。尽管存在一些重叠,ADC值仍可预示宫颈癌的组织学类型和分级。G3级肿瘤和较低的ADC值预示预后较差。两组ADC图的诊断准确性相同。要点①DWI为子宫颈癌提供了新的信息。②ADC值可以鉴别宫颈癌和正常宫颈。③治疗前ADC值可以预测根治性子宫切除术病人的预后。④ADC值有助于预示子宫颈癌的组织学类型和分级。⑤G3级肿瘤和较低ADC值病人可以从术前放化疗中受益。

Methane（CH4） is a highly potent greenhouse gas due to its high radiative forcing and global warming *** the magnitude, spatial patterns, and drivers of CH4emission from wetlands at the regional scale is crucial for formulating suitable strategies to mitigate future climate change. In this study, we synthesized the CH4flux data reported for major plant communities in the coastal salt marshes and mangrove forests in China and produced a spatial map of CH4fluxes from the mangrove sediments and salt marshes in China based on the results of machine learning models. Moreover, we examined the main drivers of CH4flux from these coastal wetlands and estimated the annual CH4emissions from the salt marshes and mangrove forests in different coastal provinces of China using a bottom-up approach. Our results showed that the mean CH4fluxes from the salt marsh and mangrove ecosystems in China were 2.22±0.29 and 2.26±0.55 mg m-2h-1, respectively. Across China, the total annual CH4emission from salt marshes was 31,179.75 Mg CH4a-1, while that from mangroves was 5,533.97 Mg CH4a-1with the sediments contributing to 12.7%(701.64 Mg CH4a-1) of the total efflux. The salt marshes and mangroves in China accounted for 2.75% and 0.14%–0.15% of the global annual CH4emissions from these two ecosystems,respectively. Moreover, we found that CH4emissions from the salt marshes and mangroves could offset the cooling impact arising from net carbon dioxide uptake by 88% and 53%, respectively, over a 100-year time scale. Mean annual temperature, soil moisture, and soil organic carbon content were the main factors controlling CH4emissions from these coastal ***, we found that CH4fluxes from the salt marshes in China decreased with latitude, which implied a possible increase in marsh CH4emission in response to global warming that should be considered carefully when developing nature-based climate solutions to achieve national goals for carbon neutrality.
