Quantum error correction is a crucial technology for realizing quantum *** computers achieve faulttolerant quantum computing by detecting and correcting errors using decoding *** error correction using neural network-based machine learning methods is a promising approach that is adapted to physical systems without the need to build noise *** this paper,we use a distributed decoding strategy,which effectively alleviates the problem of exponential growth of the training set required for neural networks as the code distance of quantum error-correcting codes *** decoding algorithm is based on renormalization group decoding and recurrent neural network *** recurrent neural network is trained through the ResNet architecture to improve its decoding *** we test the decoding performance of our distributed strategy decoder,recurrent neural network decoder,and the classic minimum weight perfect matching(MWPM)decoder for rotated surface codes with different code distances under the circuit noise model,the thresholds of these three decoders are about 0.0052,0.0051,and 0.0049,*** results demonstrate that the distributed strategy decoder outperforms the other two decoders,achieving approximately a 5%improvement in decoding efficiency compared to the MWPM decoder and approximately a 2%improvement compared to the recurrent neural network decoder.

Hepatic mucormycosis mimicking hilar cholangiocarcinoma:A case report and literature review

World Journal of Gastroenterology 2010年第8期16卷 1039-1042页

作者： Li, Ke-Wei Wen, Tian-Fu Li, gan-di Sichuan Univ W China Hosp Div Liver Transplantat Chengdu 610041 Sichuan Prov Peoples R China Sichuan Univ W China Hosp Dept Pathol Chengdu 610041 Sichuan Prov Peoples R China

Mucormycosis is a rare but invasive opportunistic fungal infection associated with a high mortality rate,and normally occurs in immunocompromised patients. In this report,we describe an immunocompetent patient suffering from hepatic mucormycosis secondary to adrenal mucormycosis,which masquerades as hilar cholangiocarcinoma. After surgical procedure and treatment with amphotericin B and itraconazole,the patient recovered well and had a 2-year infection-free survival. To our knowledge,this special clinical manifestation of hepatic infection as well as adrenal mucormycosis has not been reported to date. Mean-while,this is the first case of an immunocompetent patient with both adrenal and hepatic mucormycosis who has been treated successfully.

甘肃省张掖盆地是国家现代农业示范区,也是1990s迄今唯一农业土壤调查与区域地球化学勘查相重合的地区。笔者搜集了1990s甘肃省物探队与化探队在张掖盆地及其周围山地采集的岩石、表土层深部土壤和水系沉积物的地球化学调查数据,按照拉依达法则和采样介质计算了元素在各个地质单元中的背景值;进而以重金属为主线,采用将区域表土层深部土壤背景值与中国土壤背景值和同时期耕作层土壤平均值作对比、第四系地层土壤背景值与区域土壤背景值作对比,以及将地球化学混合模型与地理学要素相结合的方法,探讨1990s张掖盆地表土层深部土壤重金属分布特征及其物质来源。相对中国土壤元素背景值,研究区表土层深部土壤富集Cu和Cd,贫Zn;与同时期耕作层土壤相比,Cr显著富集,Cu、Zn、Pb和As显著贫化。重金属Zn、Cd和As主要源于北祁连;Pb来源于龙首山;Hg和Cr可能主要与人类活动有关;表土层深部土壤中的H3潜在生态风险指数异常是西北风和东南风共同作用的结果。重金属在表土层深部土壤中的富集程度与人类活动强度正相关,与新构造运动强度负相关。本次研究为探讨该区区域土壤环境演化提供了科学数据。

铁矿是我国的重要战略矿产资源;考虑大型矿床的发现主要源于对小型矿床的研究,本文研究洛大式菱铁矿矿床地质及成矿规律,以促进菱铁矿矿床的找矿发现。基于区域地质、区域重力异常和矿产地质调查数据,阐述矿床地质特征;进而总结成矿规律,展望找矿前景。结果表明:矿床分布于含矿建造与隐伏花岗岩类侵入体的耦合区域,控矿构造样式为羽状右行走滑断层系统,厘定的成岩期、热液期和表生期成矿过程中,热液期有石英—硫化物(Ⅰ)、石英—菱铁矿—白云石(Ⅱ)和石英—白云石—方解石(Ⅲ)三个成矿阶段,菱铁矿仅形成于第Ⅱ阶段。矿床的热液成矿作用特征显著,岩浆热液可能参与成矿,矿石结构构造具有浅成特征。结论认为,洛大式菱铁矿属于浅成中—低温热液型矿床,羽状走滑构造系统决定矿床的深部与外围找矿空间。
