 [PDF]


Management Science and Engineering (MSE) , 2014, DOI: 10.12677/MSE.2014.31B010
Abstract:

当前,国家劳动法律法规对大型企业集用工管理体制机制提出更为严格的规范要求,迫切需要企业改进劳动用工模式的顶层设计,优化劳务派遣用工策略。本研究以劳务派遣用工和合同制用工之间的互动关系“强弱”程度为对象,以岗位或业务的价值链关联程度为标准,构建劳务派遣用工模式选择的“强弱”融入模型,为规范大型企业集团劳务派遣用工方式,从根本上实现劳务派遣用工的规范化转型,提供策略选择方法和路径。

Currently, the labor laws and regulations of the state have proposed to large conglomerates a stricter specification as for their labor management system, raising an urgent need for the enterprises to improve the top-level design of their labor modes, optimizing labor dispatch as a labor strategy. This research, which sets as the object the “strong-weak” relationship of the interaction of labor dispatch and contract bound labor use; and as the standard the relevancy of the value chain of the post or business, constructs the “strong-weak” blend-in mode chosen by labor dispatch mode, which in turn serves as a way and strategy to standardize the labor dispatch mode of large conglomerates and realize fundamentally its general transition of standardization.

Review on the Dissolution of Biogenic Silica and Its Controls in the Ocean
 [PDF]


Climate Change Research Letters (CCRL) , 2013, DOI: 10.12677/CCRL.2013.23015
Abstract:
硅(Si)元素在地壳中的丰度位居第二(约占27%),也是海洋生态系统中重要的生源要素。硅作为海洋浮游植物优势组分——硅藻生长所必需的营养元素,能够形成生源硅参与到硅循环中,并且是生物泵的重要载体,因此它的生物地球化学循环与全球碳循环及全球气候变化密切相关。生源硅的溶解作为海洋硅循环的重要组成部分,贯穿于从生源硅生成、沉降到埋藏的所有环节,是连接海表到海底的桥梁。本文概述了近年来海洋中有关生源硅溶解的研究进展,从动力学方程方面探讨了影响生源硅溶解速率的因素,并介绍了四种测定生源硅溶解速率的实验方法,指出目前研究中存在的问题,展望研究重点,以期为今后海洋硅循环的研究提供背景资料。
Silicon, which represents 27% of the lithosphere, plays an important role in marine ecosystem, and it makes the linkage with the global carbon cycle and climate change, through the biological pump of CO2. Biogenic silica (BSi) is produced mainly by diatoms, which are the predominant algae in many areas of the world ocean. The dissolution be-havior of BSi can be a bridge for understanding of the ocean Si cycle, because of its close relation with the production, export and burial of BSi. In this paper, the present research progress of the marine BSi dissolution behavior are re-viewed, and the major controlling factors effected the dissolution rate of BSi are discussed from the point of dynamical equations, in addition, four methods determining the dissolution rate of BSi are introduced, including the method prob-lems at present, so as to provide background information for researching of ocean Si cycle in the future.

Abstract:
由于受数据采集时间、照射剂量、成像系统扫描的几何位置等因素的约束,计算机断层成像(CT)技术目前只能在有限角度范围或在较少的投影角度得到数据,这些都属于不完全角度重建问题。图像重建问题中的总变分(Total-Variation, TV)最小化模型使用基于交替方向法(alternating direction method, ADM)的稀疏优化算法能够在不完全角度的图像重建中获得较优的重建结果。然而,在极稀疏的角度数量下,各向同性TV最小化算法的重建精度不是很理想,存在进一步改善空间。本文针对该问题,通过基于稀疏优化的交替方向方法推导基于各向异性TV最小化的CT图像重建算法。实验结果表明,在稀疏角度重建中,本文提出的基于各向异性TV最小化重建算法与各向同性TV最小化重建算法相比,在稀疏性保持良好的基础上,重建精度上存在优势,综合性能方面表现更优异。
In many practical applications, due to the data acquisition time, dose, and geometric constraint scanning, only in a limited Angle range, various data is available to acquire. It is the so-called few-view problem. In recent years, the Total Variation (TV) minimization model, using alternating direction method (ADM) in sparse optimization algorithm shows better reconstruction results among these TV-based algorithms. However, Isotropic TV minimization based algorithms for few- view reconstruction has not so good accuracy and there is further improvement to achieve. Aiming at this problem, Anisotropic TV minimization algorithm is proposed in this paper. The algorithm is based on ADM and uses sparse optimization theory. Experimental results demonstrate that the proposed method compared with Isotropic TV minimization algorithm, has higher reconstruction accuracy and a more excellent comprehensive performance.

从耻辱到尊严:《耻》中卢里的浪漫主义情怀在后殖民语境下的解读
From Disgrace to Grace: An Analysis of Lurie’s Romanticism in Post-Colonial Context of Disgrace
 [PDF]


World Literature Studies (WLS) , 2016, DOI: 10.12677/WLS.2016.42004
Abstract:
库切的小说《耻》自问世以来便获得评论界热烈的反响。小说以平静的语言刻画人物的挣扎,将卢里个人的耻辱投放在南非后种族隔离时代的历史背景下,谱写出卢里从堕落到救赎的悲怆篇章。笔者认为小说中有四条重要线索:爱欲、诗歌、动物和歌剧。其中,对爱欲和诗歌进行语境转换下的解读是理解卢里悲剧根源的重点,而动物和歌剧则是卢里自我救赎的载体和依靠。为达到对主题的准确把脉,笔者借助热拉尔?热奈特的互文性理论来分析小说中的诗歌和歌剧。本文通过分析卢里失去身份和尊严后的自我救赎过程来解读卢里个人的浪漫主义情怀在后殖民语境下的颠覆和升华,以此展现库切对生命本身的尊严和价值的深切思考。
Coetzee’s novel, Disgrace, has aroused the extensive critical interest since its publication. With plain depiction of characters’ struggles, this novel puts Lurie’s disgrace against the background of the post-apartheid era of South Africa, composing a striking story of Lurie from disgrace to salvation. This paper proposes that there are four important motifs in the novel: sex, poetry, animal and opera. Among them, sex and poetry imply the transformation of the concept and ideology under the context of romanticism and post-colonialism which results in Lurie’s tragedy; whereas animal and opera can be interpreted as the supporters of Lurie’s self-redemption. For motifs of poetry and opera, Gérard Genette’s transtextual theory will be adopted to help illustrate the relations between different texts. Furthermore, based on the analysis of Lurie’s self-redemption after his former identity and belief are gradually undermined, this paper illustrates Coetzee’s deep contemplation and recognition of the universal significance of humanity and sublimity.
基于横向运动的频移分析—对一种新检测原理的探讨
Analysis of Frequency Shift Based on Horizontal Movement—Discussion on a Novel Detecting Principle
 [PDF]

卜德文,
Open Journal of Nature Science (OJNS) , 2016, DOI: 10.12677/OJNS.2016.41003
Abstract:
对于相对论Doppler效应,纵向和横向运动都会产生Doppler频移;在非相对论Doppler效应中,运动速度远小于光速,纵向运动会产生Doppler频移,而横向运动不会产生频移。在现实中,宏观物体的运动速度不可能接近光速,故涉及到的都是非相对论的Doppler效应。本文理论分析表明,当横向运动引起等效的纵向位移或引起纵向传播的电磁波的相位变化时,横向运动也有可能产生频移。这能够成为一种新的检测原理,用于检测运动速度和目标外形等。
For relativistic Doppler Effect, both vertical and horizontal movements can generate Doppler frequency shift. The moving velocity is much less than the speed of light in the non-relativistic Doppler Effect, the vertical movement can generate Doppler frequency shift, while the horizontal movement cannot generate frequency shift. In reality, the movement velocity of macro-object is not close to the speed of light, so it is related to the Doppler Effect of non-relativity. Theoretical analysis in this paper shows that the horizontal movement will also generate frequency shift when the movement leads to equivalent vertical displacement or phase shift of the electromagnetic wave propagating in the vertical direction. This is able to be a novel detecting principle for detecting velocity, target shape, etc.

 [PDF]

廖谦和,
Advances in Clinical Medicine (ACM) , 2016, DOI: 10.12677/ACM.2016.64026
Abstract:
Langerhans细胞组织细胞增生症(Langerhans cell histiocytosis, LCH)是一种主要由Langerhans细胞克隆性肿瘤性增生形成的肿瘤性疾病,单系统发生在淋巴结者少见,临床上经常发生误诊。本例患者男性,45岁,以发热伴右腹股沟肿块1个月余入院。光镜下淋巴结基本结构几乎完全被破坏,病变主要由Langerhans细胞和嗜酸性细胞或嗜酸性脓肿组成。Langerhans细胞中等至偏大,胞质丰富嗜酸性,细胞核圆形、卵圆形,咖啡豆样核或不规则,有明显的核沟纹。病灶中有散在的多核巨细胞和数量不等的嗜酸性粒细胞浸润,可见嗜酸性脓肿。免疫组化标记显示瘤细胞表达S-100、CD1a、CD68、vimentin,而不表达HMB45,CD21、CD45、CD20、CD3、CK、CD30、EMA。患者术后恢复良好。
Langerhans cell histiocytosis (LCH) is a neoplastic diseases majorly formed by the clonal neoplastic proliferation of Langerhans cells, and single-system which occurs in the lymph nodes is rare. So the clinical misdiagnosis often occurs. In this case, a 45-year-old man was admitted to hospital with a history of fever and a right groin mass for more than one month. Under microscopy, the structure of the lymph node was almost damaged, which was caused by the idiopathic proliferation of Langerhans cell and eosinophils or eosinophilic abscess. The Langerhans cells ranged from medium to relatively large in size and the cytoplasm is rich and eosinophilic. The nuclear was round, oval, bean-like or irregular in shape, showing clear grooves and depressions. Immunohistochemical study showed that the Langerhans cells were strongly positive for S-100 protein, CD1a, CD68, vimentin, and negative for HMB45, CD21, CD45, CD20, CD3, CK, CD30, EMA. The patient was recovered well after surgery.
