简介：为强子的激发QCD的模型预言让比夸克反夸克介子和原来的quark-parton的三夸克的baryons更复杂的结构当模特儿的异国情调的强子的一个分类。这些包括pentaquarkbaryons，六夸克的H-dibaryon，和tetraquark，混血儿和glueball介子。尽管有广泛的试验性的搜索，任何这些异国情调的配置的不含糊的候选人都没被识别。在另一方面，很多个介子说，似乎是一个质子反质子界限状态的，和包含任何一个charmed-anticharmed夸克的其它配对或bottom-antibottom夸克配对，最近被发现了那也不适合进夸克反夸克介子图画也不匹配启发QCD的exotics的期望的性质。这里，我简短为H-dibaryon从最近的搜索考察结果，并且讨论最新发现的状态的一些性质质子反质子状态和所谓的XYZ介子--并且为常规夸克反夸克介子和预言的QCD异国情调的状态把他们与期望作比较。

简介：我们在场为电可擦可编程只读存储器记忆的一个新感觉放大器电路。感觉放大器的拓扑学使用察觉到方法的电压，有象高可靠性一样的低成本和低动力消耗量。感觉放大器在与嵌入的电可擦可编程只读存储器处理的一个SMIC0.35-μm2P3M互补金属氧化物半导体认识到的一个电可擦可编程只读存储器被实现。在电力供应是3.3V的条件下面，模拟结果证明费用时间是在建议感觉放大器的35ns，并且最大值在read时期期间平均当前的消费，这是40μA。新奇拓扑学允许电路与象1.4V一样低的电力供应工作。感觉放大器为RFID标签IC应用在2-kb电可擦可编程只读存储器记忆被实现了，并且有240仅仅μm2的一个硅区域。
