From 1644 to 2003,many Chinese historians and novelists debated the existence and the identity of a provincial graduate from Qi county in Henan province who reportedly helped the commoner rebel Li Zicheng overthrow the Ming polity(1368—1644)only to be suspected of disloyalty and killed by the rebel leader,thus clearing the way for the Qing that ruled China from 1644 to *** 2004 there was discovered a genealogical manuscript that goes far towards solving the Li Yan puzzle and allows us to see how rumors were incorporated into histories and literary works that appealed to a wide variety of people over the course of three and a half *** this essay,I compare and contrast the emerging mythistorical figure of Li Yan with other scholar-rebel-advisors in Chinese and world history and suggest that he was most akin to the Lord Chancellor Thomas More in sixteenth-century England who spoke truth to power and was celebrated in twentieth-century history and 1让erature.

AIMTo describe magnetic resonance (MR) imaging features of pancreatic neuroendocrine neoplasms (PanNENs) according to their grade and tumor-nodes-metastases stage by comparing them to histopathology and to determine the accuracy of MR imaging features in predicting their biological *** study was approved by our institutional review board; requirement for informed patient consent was waived due to the retrospective nature of the study. Preoperative MR examinations of 55 PanNEN patients (29 men, 26 women; mean age of 57.6 years, range 21-83 years) performed between June 2013 and December 2015 were reviewed. Qualitative and quantitative features were compared between tumor grades and stages determined by histopathological *** defined margins were more common in G2-3 and stage III-IV PanNENs than in G1 and low-stage tumors (P -3 mm2/s vs 1.45 × 10-3 mm2/s and 1.10 × 10-3 mm2/s vs 1.53 × 10-3 mm2/s, P = 0.003 and 0.001). Receiving operator characteristic analysis determined optimal cut-offs of 1.21 and 1.28 × 10-3 mm2/s for the identification of G2-3 and stage III-IV tumors, with sensitivity and specificity values of 70.8/80.7% and 64.5/64% (95%CI: 48.7-86.6/60-92.7 and 45.4-80.2/42.6-81.3).CONCLUSIONMR features of PanNENs vary according to their grade of differentiation and their stage at diagnosis and could predict the biological behavior of these tumors.

This paper describes an improved algorithm for fuzzy c-means clustering of remotely sensed data, by which the degree of fuzziness of the resultant classification is de- creased as comparing with that by a conventional algorithm: that is, the classification accura- cy is increased. This is achieved by incorporating covariance matrices at the level of individual classes rather than assuming a global one. Empirical results from a fuzzy classification of an Edinburgh suburban land cover confirmed the improved performance of the new algorithm for fuzzy c-means clustering, in particular when fuzziness is also accommodated in the assumed reference data.

This paper explores the internationalization of higher education initiatives of Hong Kong,being one of the Special Administrative regions(SAR)of China,within the context of the Chinese Mainland-Hong Kong(CM-HK)***,social,economic,and political ties between Hong Kong and the Mainland of China,their economic and political interdependency,and a time series analysis of Hong Kong’s University Grants Committee(UGC)statistical data(local and non-local participation,geographic composition,and cost analysis of UGC-funded programs)are used to support what the author calls the“intra-nationalization of higher education.”This forms a unique internationalization strategy,whereby a sub-national region such as Hong Kong and possibly Macao,orients its internationalization strategy towards a motherland,in this case China.

Dear Editor, Intrauterine insemination （IUI） is mainly indicated in cases of unexplained or mild male subfertility. In these cases, gonadotropin ovarian stimulation combined with gonadotropin-releasing hormone （GnRH） antagonist IUI leads to up to an 18% delivery rate per attempt.1 However, when the number of motile spermatozoa inseminated is lower than 1× 10^6, the success rate drops below 5%.1 Since semen quality varies intra-individually, this threshold may not be reached on the day of IUI. In such cases, some authors have suggested asking men to provide two consecutive ejaculates and to perform IUI with the pooled spermatozoa.2 However, the effectiveness of IUI with pooled ejaculates is not dear3.

The Beryl Embayment is situated at the south end of the North Viking Graben in the North Sea. Three sets of normal faults, with N-S, NW-SE and NE-SW orientations, have been recognized in the Beryl Embayment. High-resolution subsidence analysis of 73 wells, combined with some seismic data, has been used to document Middle to Late Jurassic subsidence patterns in this area. The high temporal resolution achieved （1 to 2 million years per data point） has also allowed an assessment to be made of temporal evolution of faults with different orientations, and a study made of how and when the East Shetland Fault was linked and controlled sedimentary facies distributions. The results indicate that the East Shetland Fault can be divided into northern and southern parts which were linked together during the Early-Mid Oxfordian. The Mid-Late Jurassic syn-rift phase can be divided into four stages： minor active extension stage during the Bathonian-Middle Callovian, early syn-rotational stage during the Late Callovian-Early-Mid Oxfordian, syn-rotational climax stage during the Late Oxfordian-Early Volgian, and late syn-rotational stage during the Mid-Late Volgian. The results also show that there was a sequential variation of extension direction of active normal faults with different orientations, with an overall shift in the dominant orientation of active normal faults from N-S in the Bathonian-Middle Oxfordian, through NNW-SSE in the Late Oxfordian-Early Volgian （≈N30°E）, to NW-SE （≈N45°E） in the Mid-Late Volgian.

The Robogymnast is a triple link underactuated pendulum that mimics a human gymnast hanging from a horizontal *** this paper, two multi-objective optimization methods are developed using invasive weed optimization（IWO）. The first method is the weighted criteria method IWO（WCMIWO） and the second method is the fuzzy logic IWO hybrid（FLIWOH）. The two optimization methods were used to investigate the optimum diagonal values for the Q matrix of the linear quadratic regulator（LQR） controller that can balance the Robogymnast in an upright configuration. Two LQR controllers were first developed using the parameters obtained from the two optimization methods. The same process was then repeated, but this time with disturbance applied to the Robogymnast states to develop another set of two LQR controllers. The response of the controllers was then tested in different scenarios using simulation and their performance evaluated. The results show that all four controllers are able to balance the Robogymnast with varying accuracies. It has also been observed that the controllers trained with disturbance achieve faster settling time.
