TL;DR: In this paper, the optimal proxy variance for the sub-Gaussianity of the Beta distribution has been shown for the symmetric (around its mean) case and the non-symmetrical case.
Abstract: We obtain the optimal proxy variance for the sub-Gaussianity of Beta distribution, thus proving upper bounds recently conjectured by Elder (2016). We provide different proof techniques for the symmetrical (around its mean) case and the non-symmetrical case. The technique in the latter case relies on studying the ordinary differential equation satisfied by the Beta moment-generating function known as the confluent hypergeometric function. As a consequence, we derive the optimal proxy variance for the Dirichlet distribution, which is apparently a novel result. We also provide a new proof of the optimal proxy variance for the Bernoulli distribution, and discuss in this context the proxy variance relation to log-Sobolev inequalities and transport inequalities.

TL;DR: In this paper, a wireless network receiver or proxy is contacted, and one or more client identifiers are received from the contacted receiver, and coordinate information is also received from a receiver or a proxy.
Abstract: This application is directed to systems and methods for surveying a wireless network site. A wireless network receiver or proxy is contacted. One or more client identifiers are received from the contacted receiver or proxy. Coordinate information is also received from the contacted receiver or proxy. The received client identifiers are correlated with the received coordinate information. RF signal characteristic data is received from the contacted wireless network or proxy. Survey data is stored based on the received client identifiers, coordinate information, and RF signal characteristic data.

TL;DR: In this paper, the authors propose a method and apparatus in a distributed data processing system for providing proxy services, where requests are processed by a primary proxy, using a shared memory.
Abstract: A method and apparatus in a distributed data processing system for providing proxy services. Requests are processed by a primary proxy, using a shared memory in the distributed data processing system. A challenge from a secondary proxy to the primary proxy is detected. A determination is made as to whether the secondary proxy has priority over the primary proxy. This may be determined using priorities assigned to the proxies. Responsive to determining whether the secondary proxy has priority over the primary proxy, a priority of the secondary proxy is stored. Responsive to the secondary proxy having priority over the primary proxy, the secondary proxy to is allowed access the shared memory. Further, the secondary proxy is then allowed to multi-cast a message to clients indicating the secondary proxy's location. This message indicates that the secondary proxy is now the primary proxy.
