We propose a method for learning landmark detectors for visual objects (such as the eyes and the nose in a face) without any manual supervision. We cast this as the problem of generating images that combine the appearance of the object as seen in a first example image with the geometry of the object as seen in a second... | Görsel nesneler için (örneğin bir yüzün gözleri ve burnu gibi) herhangi bir elle denetim olmadan belirleyici dedektörleri öğrenmeye yönelik bir yöntem öneriyoruz.

We estimate the rate at which the proposed space gravitational-wave interferometer LISA could detect intermediate-mass black-hole binaries, that is, binaries containing a black hole in the mass range 10 -- 100 Msun orbiting a black hole in the mass range 100 -- 1000 Msun. For one-year integrations leading up to the inn... | 我们估算了拟议的空间引力波干涉仪LISA探测中等质量黑洞双星（即其中一个黑洞质量在10至100倍太阳质量之间，围绕另一个质量在100至1000倍太阳质量之间的黑洞运行）的速率。对于持续一年、直至最内层稳定轨道的积分，且信噪比为10的情况下，我们估计10倍太阳质量/100倍太阳质量双星的探测速率仅为每百万年1次。该估算采用通过匹配滤波进行参数估计的方法，结合了LISA科学团队在线公布的LISA噪声曲线，并采用了Miller（2002）使用的中等质量黑洞形成率模型。我们发现，可探测距离对LISA臂长或加速度噪声相对不敏感，但大致与LISA的位置误差成反比，并且大致随积分时间T（以年为单位）的平方根（T^(1/2)）变化。我们还表明，尽管... | zh |

The purpose of this paper is to develop the theory of holomorphic gerbes on complex tori in a manner analogous to the classical theory for line bundles. In contrast to past studies on this subject, we do not restrict to the case where these gerbes are torsion or topologically trivial.
