A Boolean map theory of visual attention

A theory is presented that attempts to answer two questions. What visual contents can an observer consciously access at one moment? Answer: only one feature value (e.g., green) per dimension, but those feature values can be associated (as a group) with multiple spatially precise locations (comprising a single labeled Boolean map). How can an observer voluntarily select what to access? Answer: in one of two ways: (a) by selecting one feature value in one dimension (e.g., selecting the color red) or (b) by iteratively combining the output of (a) with a preexisting Boolean map via the Boolean operations of intersection and union. Boolean map theory offers a unified interpretation of a wide variety of visual attention phenomena usually treated in separate literatures. In so doing, it also illuminates the neglected phenomena of attention to structure.     

中医的"证"与人体"状态"

近年来在证的研究中 ,像“机体反应状态”、“机体宏观状态”、“整体功能态”、“异常机能状态”、“综合性的功能态”、“应变态势”等等一些类似的语词常被用来说明证的内涵。这些来自不同角度的称谓之间虽然有些细微差异 ,但大都认为证是人体的一种异常状态。甚至有人干脆说中医学就是状态医学[1] 。那么什么是状态 ?证为什么能够称作状态 ?把证看成状态又有什么意义呢 ?对这些问题目前尚缺乏一个通盘的论证。1　状态是什么状态作为一个哲学范畴具有相当老的资格 ,在亚里士多德的“十范畴表”中它就占了一席 ,他指出 :“状态则是一种很…

Efficient spatio-temporal data mining with GenSpace graphs

We describe a method for spatio-temporal data mining based on GenSpace graphs. Using familiar calendar and geographical concepts, such as workdays, weeks, climatic regions, and countries, spatio-temporal data can be aggregated into summaries in many ways. We automatically search for a summary with a distribution that is anomalous, i.e., far from user expectations. We repeatedly ranking possible summaries according to current expectations, and then allow the user to adjust these expectations. We also choose a propagation path in the GenSpace subgraph that reduces the storage and time costs of the mining process.     

自我概念对主观幸福感预测的内隐社会认知研究

从内隐社会认知的观点出发研究自我概念和主观幸福感的结构,并在此基础上探讨自我概念对主观幸福感的影响,得到以下结论:在中国大学生样本中(1)自我概念是双重的,存在外显自我和内隐自我两种成分;(2)主观幸福感结构是双重的,存在外显幸福感和内隐幸福感两种成分;(3)自我概念对主观幸福感的预测模型为:外显自我预测外显幸福感,内隐自我预测内隐幸福感。

探测金星的历程(一)

除太阳、月亮之外金星是天空中肉眼能够看到的最明亮的星,最亮的时候达4．4等,比全天最亮的恒星天狼星还亮14倍。金星是太阳系九大行星中距离太阳第二近的行星,也是距离地球最近的行星。我国古代称之为太白,早上出现在东方时又叫启明、晓星、明星,傍晚出现在西方时也叫长庚、黄昏星。金星接受的阳光比地球多了一倍,笼罩金星的厚密云层将大约75％的阳光反射到空间,使它变得光彩夺目。无论从年龄、体积、形态、密度, 还是诞生时的环境上看,金星都与地球非常相似, 因此被称为地球的“姐妹星”,人们猜测那里可能     

胸腺肽对心理应激引起老年大鼠免疫功能降低的改善作用

研究胸腺肽作为一种免疫增强剂,是否参与调节应激对免疫系统的作用,心理应激采用可控／不可控电击的模型。结果表明,受到６天,每天半小时的可控或不可控的足底电击后,与不受电南的对照组相比,不可控组老年大鼠的免疫功能明显下降,而可控组没有明显变化．;肾上腺糖皮质激素的分泌量在受到电击后显著升高。
