A report by Sarah Tofte of Human Rights Watch, a pressure group, found that at least five states required men to register if they were caught visiting prostitutes. At least 13 required it for urinating in public (in two of which, only if a child was present). No fewer than 29 states required registration for teenagers who had consensual sex with another teenager. And 32 states registered flashers and streakers.

In late winter, while his mate stays on the nest with their clutch of two or three eggs, the male heads off to find food for both of them, carrying rats, mice, and squirrels back to the nest.

在冬末，而它的伴侣停留在巢内孵化两个或三个蛋，雄猫头鹰去寻找食物为它们两口，运输大鼠，老鼠，松鼠回巢。

In this thesis, using three partly entangled pairs as the quantum channel, we present a scheme for probabilistically teleporting an unknown three-particle entangled state by means of the optimal discrimination between two nonorthogonal quantum states.

在本论文中，使用三个非最大的纯纠缠对作为量子通道，通过对两个非正交量子态的最佳识别，我们提出了一个概率量子隐形传送三粒子纠缠态的理论方案。

San Francisco-based interaction designer Timm Kekeritz, who was born and raised in Schleswig-Holstein, Germany, decided to combine two elements that he found being constantly underestimated: infographics and the importance of water.

互动设计师 Timm Kekeritz 在德国 Schleswig-Holstein 出生和长大，现在居住在三藩市，他决定将资讯图像和水的重要性这两个元素结合起来–他觉得这两个元素长期以来都被人们所低估。

Using hundreds of computers, Choptuik and Pretorius calculated the gravitational interactions between the colliding particles and found that a black hole does form if the two particles collide with a total energy of about one-third of the Planck energy, slightly lower than the energy predicted by hoop conjecture, as they report in a paper in press at Physical Review Letters .

肖普提克和普雷托里斯运用了几百台计算机，计算了两个对撞粒子之间的引力作用。他们发现，如果两个粒子对撞的总能量为普朗克能量的大约三分之一，确实可以形成一个黑洞，这个能量比环绕猜测中所预测的稍微低一点。他们在《物理评论快报》杂志纸质版的一篇论文中报道了该发现。
