A STATISTICAL NOISE MODEL AND MATHEMATICAL MODEL OF SPECKLE PATTERN AND ADAPTIVE FILTERING APPROACH

引用

Journal of Electronics(China) 1995年第1期12卷 24-32页

作者：杨亦兵何振亚 Southeast University Nanjing 210096

A statistical noise model and a mathematical model for real speckle pattern are presented in this paper, and then, in view of the models, a new adaptive suboptimal image filtering approach is proposed. The proposed approach, with the local direction features of speckle pattern, combines the characteristics of optimal linear filter with non-linear filter and is an adaptive approximation to linear minimum mean square error filter. Experimental results show that the proposed approach has fairly good edge-preserved performance, compared with other present image filters, as well as much better filtering performance and robustness for speckle pattern.

Carbon is a versatile element in the Periodic Table and can bind itself to many polymorphs through various bonding forms(e.g.,sp,sp2,and sp3 hybridizations)[1].Based on structural periodicity,carbon materials can be classified into crystalline or amorphous[2].For example,graphene,diamond and graphite are well-known crystalline carbon materials with different periodic binding motifs in the carbon atom networks[3‒5].By contrast,the active carbons featured with high porosity are the typical amorphous carbons in which the carbon atoms are arranged in a disordered fashion[6].

STEM领域的拔尖女生是青年女性科技人才的重要后备军,因人数较少往往成为统计意义上易被忽略的微群体,其生涯选择困境难以被真正看到。本文运用质性研究方法,对某顶尖大学拔尖计划2020—2022年本科在读、中途选择分流以及临近毕业的女生进行了多轮次、多角度深度访谈,并结合对拔尖男生群体的访谈进行多重情境与主题对比分析。研究发现:我国STEM拔尖女生的科研生涯选择主要受能力觉悟、情感倾向和关系支持三个维度的影响,关系支持是她们面临科研生涯选择时的关键影响因素;来自多重“关心圈层”的关心由于忽视了女性路径的存在与价值,而导致拔尖女生群体职业选择时陷入“关心困境”。本文为关注和理解STEM拔尖女生的成长与发展提供两项教育切入策略,即关心过程的具体化和教育过程的平等化。

目的:通过观察EGFR、NF-κB蛋白表达与鼻咽癌放射敏感性的关系,评价两因子在预测鼻咽癌放射敏感性方面的作用,并为以后靶向基因治疗鼻咽癌、提高放疗效果提供理论依据。方法:采用免疫组织化学SP法检测41例鼻咽癌组织中EGFR及NF-κB的表达情况,并通过随访及临床观察,判断每例患者放疗效果,从而将所有患者分为完全缓解组、部分缓解/稳定组和进展组,评定两因子表达水平与放射敏感性的关系。结果:EG-FR、NF-κB在鼻咽癌中均有不同程度表达,两者在鼻咽癌组织的不同放射敏感性中表达各具有差异性(P0.05)。两因子表达与鼻咽癌放射敏感性呈负相关。结论:EGFR、NF-κB可能成为预测鼻咽癌放射敏感性的2个重要指标,为鼻咽癌患者的靶向基因治疗提供理论依据。
