Patterning of L10 FePt nanoparticles(NPs) with high coercivity offers a promising route to develop bit-patterned media(BPM) for the next generation magnetic data recording system, but the synthesis of monodisperse FePt NPs and mass production of their nanopatterns has been a longstanding challenge. Here, highly efficient nanoimprint lithography was applied for large-scale universal patterning, which was achieved by imprinting the solution of a single-source bimetallic precursor. The rigid coplanar metallic cores and the surrounding flexible tails in the bimetallic complex permit the spontaneous molecular arrangements to form the highly ordered negative morphology replicated from the soft ***-situ pyrolysis study was then investigated by one-pot pyrolysis of the precursor under an Ar/H2 atmosphere, and the resultant NPs were fully characterized to identify the phase,morphology and magnetic properties. Finally, highly-ordered patterns on certain substrates were preserved perfectly after pyrolysis and could be potentially utilized in magnetic data recording media.

针对神东矿区布尔台煤矿首个综采放顶煤工作面回采过程中频繁出现的端面漏冒及片帮问题,采用现场实测、数值模拟等方法研究42103综放面端面片帮、漏冒特征及其影响因素。基于现场实测统计,分析了42103综放面端面片帮冒顶程度及分布特征,建立了端面冒高与支架端面距及支架阻力之间的回归方程,得出煤岩体冒高、片帮与端面距呈线性正相关,与支架工作阻力为倒幂函数相关性关系,煤岩体冒高与片深呈对数相关关系。在此基础上,模拟优化该综放面端面漏冒防控技术参数,即两柱掩护式支架综放面端面距小于0.75m、支架工作阻力大于12000kN时的端面顶板控制效果好。研究成果为神东矿区类似开采条件以及布尔台矿后续综放工作面的安全高效开采提供参考。

Asherman's syndrome(AS) is a common disease that presents endometrial regeneration disorder. However, little is known about its molecular features of this aregenerative endometrium in AS and how to reconstruct the functioning endometrium for the patients with AS. Here, we report that ΔNp63 is significantly upregulated in residual epithelial cells of the impaired endometrium in AS; the upregulated-ΔNp63 induces endometrial quiescence and alteration of stemness. Importantly, we demonstrate that engrafting high density of autologous bone marrow mononuclear cells(BMNCs) loaded in collagen scaffold onto the uterine lining of patients with AS downregulates ΔNp63 expression, reverses ΔNp63-induced pathological changes, normalizes the stemness alterations and restores endometrial regeneration. Finally, five patients achieved successful pregnancies and live births. Therefore, we conclude that ΔNp63 is a crucial therapeutic target for AS. This novel treatment significantly improves the outcome for the patients with severe AS.

Precision agriculture, and more specifically Site-Specific Crop Management(SSCM), has been implemented in some form across nearly all agricultural production systems over the past 25 years. Adoption has been greatest in developed agricultural countries. In this review article, the current situation of SSCM adoption and application is investigated from the perspective of a developed(UK) and developing(China) agricultural economy. The current state-of-the art is reviewed with an emphasis on developments in position system technology and satellite-based remote sensing. This is augmented with observations on the differences between the use of SSCM technologies and methodologies in the UK and China and discussion of the opportunities for(and limitations to)increasing SSCM adoption in developing agricultural economies. A particular emphasis is given to the role of socio-demographic factors and the application of responsible research and innovation(RRI) in translating agritechnologies into China and other developing agricultural economies. Several key research and development areas are identified that need to be addressed to facilitate the delivery of SSCM as a holistic service into areas with low precision agriculture(PA) adoption. This has implications for developed as well as developing agricultural economies.

距离测度是毕达哥拉斯(Pythagorean)模糊决策的一个基本概念,其在用权重向量进行有序集成运算、有序加权距离和相似度构造时具有重要作用。然而,早期发表于International Journal of Intelligent Systems中的文章Extension of TOPSIS to multiple criteria decision making with Pythagorean fuzzy sets,在首次引入海明距离测度时,对距离公理化条件的证明存在不妥。为此,通过反例和分析指出了其在证明公理化条件的有界性和三点不等式时存在的错误,并统筹考虑犹豫度的绝对值项和其他绝对值项,通过分情况讨论给出了海明距离测度的严格证明,进一步,证明了其推广形式(欧几里得距离测度)的公理化条件。
