一种用于宽动态范围上的高精度散射测量的标准方法

The co-effect of transmitted power fluctuation and system nonlinearity produce deviations in scatterometer measurement results . An internal calibration method to deal with this problem is proposed. The method can result in more precise scatterometric measurements in a wide range. The basic principle of the method is combining real-transmitted-power detection with the calibration of system nonlinearity. A practical scheme to implement the method is also presented, which is developed based on a special designed mechanism of a microwave radiometer-scatterometer combined system.

Using sexually explicit material in a therapeutic context

For most of us, sex is a subjective, lived experience that is as unique as our genetic make-up, our upbringing, our thoughts, values, feelings, beliefs and ideas. It is through our erotic interactions, or the absence thereof, that we form aspects of our fluid and mutable erotic paths and identities. Despite the proliferation of sexual imagery throughout our culture, many of us still struggle with what sex means to us, what we do, how we experience it and what that says about who we are as people. Some who struggle with this may seek the services of a psychosexual sex therapist. This paper aims to explain how such services function, why they are necessary and how the use of sexually explicit material, in some psychosexual therapeutic contexts, can help unravel the mixed responses we have to sex and our social conditioning, and enhance our overall relationship to eroticism, pleasure and general well-being.     

渐进运动对恶化肺部真菌感染的斑点追踪治疗

目的:研究渐进运动对恶化性肺部真菌感染的感染过程,分析斑点追踪指导治疗方法对肺部真菌感染恶化过程的临床指导。方法:以某运动疾病康复治疗医院从2014年1月到2014年3月收治的85例肺部真菌感染患者为分析对象,对患者的肺部真菌感染过程进行全程监控,对恶化过程每天进行观察记录,综合提取肺部真菌感染的斑点分布特性与斑点运动特性,比较伊曲康唑、霉素B脂质体、氟康唑三种药物代谢过程的斑点特性,给出真菌感染度及恶化趋势,最后采用相应药物进行治疗。结果:不同感染和恶化程度的肺部真菌感染斑点分布复杂,运动特性各异,随着真菌感染恶化加剧,斑点分布更加随机化,且运动特性明显加剧。结论:渐进运动对渐进恶化性的肺部真菌感染的斑点追踪具有很好的临床参考价值,可以依据斑点特性对肺部真菌感染恶化特性做出准确预测。     

Sexually Dimorphic Tridimensionally Preserved Pterosaurs and Their Eggs

<正>The pterosaur record is generally poor,with little information about their populations,and pterosaur eggs are even more rare,with only four isolated and flattened eggs found to date.Dr.WANG Xiaolin,Institute of Vertebrate Paleontology and Paleoanthropology(IVPP)of the Chinese Academy of Sciences(CAS),and his team revealed a new pterosaur-rich area with potentially thousands of bones,including tridimensionally preserved male and female skulls and eggs discovered together for the fi rst time in the Early Cretaceous deposit of the TurpanHami Basin,south of the Tian Shan Mountains in Xinjiang Uygur Autonomous Region,northwestern China.On June 6,the researchers reported online a population of a new sexually dimorphic pterosaur species(Hamipterus tianshanensis gen.et sp.nov.),with five exceptionally well-preserved three-dimensional eggs in Current Biology,providing new and important evidence regarding male and     

Abuse of power in relationships and sexual health

STI rates are high for First Nations in Canada and the United States. Our objective was to understand the context, issues, and beliefs around high STI rates from a nêhiyaw (Cree) perspective. Twenty-two in-depth interviews were conducted with 25 community participants between March 1, 2011 and May 15, 2011. Interviews were conducted by community researchers and grounded in the Cree values of relationship, sharing, personal agency and relational accountability. A diverse purposive snowball sample of community members were asked why they thought STI rates were high for the community. The remainder of the interview was unstructured, and supported by the interviewer through probes and sharing in a conversational style. Modified grounded theory was used to analyze the narratives and develop a theory. The main finding from the interviews was that abuse of power in relationships causes physical, mental, emotional and spiritual wounds that disrupt the medicine wheel. Wounded individuals seek medicine to stop suffering and find healing. Many numb suffering by accessing temporary medicines (sex, drugs and alcohol) or permanent medicines (suicide). These medicines increase the risk of STIs. Some seek healing by participating in ceremony and restoring relationships with self, others, Spirit/religion, traditional knowledge and traditional teachings. These medicines decrease the risk of STIs. Younger female participants explained how casual relationships are safer than committed monogamous relationships. Resolving abuse of power in relationships should lead to improvements in STI rates and sexual health.
