The Saljuq Turks’ Conversion to Islam: The Crusading Sources

This article contributes to the important debate over the conversion of the Turks to Islam. Previously, it was thought that the Turks abandoned their former steppe faith and customs very swiftly to become staunch Sunni Muslims, but this view has recently been challenged by a number of studies. The current consensus seems to be that the Turks’ adoption of Islam was a process of far longer duration, spanning many decades. This article broadens this discussion by demonstrating that the chronicles written by the First Crusaders contain much useful information that is pertinent to this question. It works through these texts, showing that they can shed new light on this point.     

基于负样本多通道优化SSD网络的钢铁厂提取

准确提取钢铁厂对去产能监测和环境保护具有重要意义。传统的人工目视解译方法效率低、成本高,无法满足开展大区域钢铁厂监测的需求。以深度学习目标检测网络SSD为基础,构建面向遥感影像钢铁厂提取的深度学习目标检测网络,提出maxout模块,将负样本通路优化为多分支结构,突出难分负样本特征并提升网络对无用特征的抵制效果。利用国产GF-1数据对京津冀地区的钢铁厂进行快速自动提取实验。与人工解译的钢铁厂点位数据的对比表明,该目标检测方法的提取精度达到80%以上。     

Why super sandstorm 2021 in North China?

Severe sandstorms reoccurred in the spring of 2021 after an absence for more than 10 years in North China. The dust source area, located in Mongolia, suffered destructive cooling and warming in early and late winter, which loosened the land. A lack of precipitation, excessive snow melt and strong evaporation resulted in dry soil and exiguous spring vegetation. A super-strong Mongolian cyclone developed on the bare and loose ground, and easily blew and transported large amounts of sand particles into North China. Furthermore, top-ranking anomalies (sea ice shift in the Barents and Kara Sea, and sea surface temperatures in the east Pacific and northwest Atlantic) were found to induce the aforementioned tremendous climate anomalies in the dust source area. Analyses, based on large-ensemble Coupled Model Intercomparison Project Phase 6, yield results identical to the reanalysis data. Thus, the climate variabilities at different latitudes and synoptic disturbances jointly facilitated the strongest spring sandstorm over the last decade.     

AQP-1和AQP-5在卵巢上皮性肿瘤的表达及临床意义

目的探讨AQP1及AQP5在卵巢上皮性肿瘤的表达及临床意义。方法采用免疫组化法检测105例卵巢上皮性肿瘤和10例正常卵巢组织AQP1和AQP5蛋白的表达。结果AQP1主要表达于毛细血管及小血管内皮细胞．而AQP5表达于卵巢肿瘤细胞。随着卵巢上皮性肿瘤由良性向恶性发展,AQP1和AQP5的表达逐渐增加（P〈0．05）。Ⅲ、Ⅳ期卵巢癌AQP1的表达明显高于Ⅰ、Ⅱ期（P〈0．05）,伴淋巴转移者AQP1明显高于无淋巴转移者（／9〈0．05）;腹水大于1000mL者AQP1和AQP5的表达明显高于小于1000mL者（P〈0．01）：低分化卵巢癌AQP5的表达明显高于高、中分化者（P〈0．05）;AQP1及AQP5的表达与腹水量呈正相关（r分别为0．40,0.31;P〈0．05）。结论AQP1和AQP5高表达与卵巢癌的发生、发展及预后有关,可能是卵巢癌腹水产生的主要原因。     

公共知识中心与公共知识管理——再论图书馆的本质和定义

图书馆是一个发展中的概念。当前,图书馆的定义有很大局限性。公共知识资源应是图书馆的本质内容;公共知识管理是图书馆的本质职能;知识共享与知识保障是社会对图书馆的本质要求。“公共知识中心”这一概念能更加准确地反映图书馆的本质。图4。参考文献18。

地表模型上的最短路径算法研究

本文提出了一种基于空间三角网格表示的地表模型上的最短路径算法,该算法利用离散点的空间信息计算得到起点到周围邻接点的最短距离,然后利用逐步向外层边界扩展的方法扩大起点的邻接点范围,直到起点的邻接点中包含终点,此过程可求得s0到t0的最短路径上的关键点,然后求取无原始边连接的两个关键点之间的精确路径点。
