The use of ultrasound in the diagnosis of axillary lymph node metastases from breast cancer in a Chinese population was investigated. Data for 1,049 with breast cancer were retrospectively collected. All patients had undergone pre-operative axillary ultrasound and then axillary lymph node dissection. The sensitivity, specificity and accuracy of axillary ultrasound in this cohort were 69.4%, 81.8%...
A hybrid simulator is a simulator which embeds a hardware experiment in a numerical simulation. However, the hybrid simulator is generally subjected to an inherent problem of energy increase in collision of two hardwares in the loop because of delay times. To solve this problem, Osaki et al. proposed a compensation method of delay time that can realize a variable coefficient of restitution [1]. However,...
In the three-dimensional sensor network scenarios, a three-dimensional positioning algorithm, according to the bounding cube algorithm, which is based on the intersection of the ball field for wireless sensor networks, is presented. Also, possible coordinates of the unknown nodes are determined. The principle of this algorithm is studied and realization method of simulation is experimented by MATLAB...
Fleet collaborative decision-making (CDM) has already become a hot topic in modern military decision-making. The fleet CDM of defending against incoming threats is discussed based on integrative method of qualitative analysis and quantitative experimental validation. We put forward three kinds of important effect factors of fleet collaborative decision-making and three hypotheses in accordance with...
The structural vibration mode can be used as the characteristics parameters for identification of structural damage, achieving the positioning of structural damage through the wavelet transform. However, the identification of structural damage nearby information borders cannot be obtained due to the border effects. As vibration information borders are areas with larger structure loading effect, it...
Intertextuality is the way that we relate textual occurrences to each other and recognizes them as signs which evoke whole areas of our previous textual experience. It is very important to recognize intertextuality for understanding and translating works, especially classics. This paper proposes a framework and four types of measurements to compute intertextuality, namely, Dice coefficient, Jaccard...
