    摘要： A catalyst is synthesized by a method in which a catalytic metal such as platinum or another noble metal is dispersed onto a support member. A transition metal macrocycle is also adsorbed onto the support, and the support is heat treated so as to at least partially pyrolyze the macrocycle and anchor the transition metal to the support. The catalytic metal is alloyed with the transition metal either during the pyrolysis step, or in a separate step. The catalyst has significant utility in a variety of applications including use as an oxygen reduction catalyst in fuel cells.

    摘要： A composite material having utility as an anode for lithium ion batteries comprises silicon, a transition metal, a ceramic and an electrically conductive diluent such as carbon. In particular instances, the ceramic is electrically conductive, and may comprise vanadium carbide or tungsten carbide. The transition metal may, in some instances, comprise iron. The material may be fabricated by grinding together a starting mixture of the components, and grinding may be accomplished in a high impact ball milling process, and the grinding step may cause partial alloying of the silicon with the metal and/or carbon. Further disclosed is a method for making the material as well as electrodes which incorporate the material.

    摘要： Communications between server computer systems of a cluster routinely exchange notice of configuration status and, on demand, transmit updated configuration data sets. Each status message identifies any change in the local configuration of a servers and, further, includes encrypted validation data. Each of the servers stores respective configuration data including respective sets of data identifying the servers known to the respective servers as participating in the cluster. Each status message, as received, is validating against the respective configuration data stored by the receiving server. A status message is determined valid only when originating from a server as known by the receiving server, as determined from the configuration data held by the receiving server. Where a validated originating server identifies updated configuration data, the receiving server requests a copy of the updated configuration data set, which must also be validated, to equivalently modify the locally held configuration data. The configuration of the cluster thus converges on the updated configuration.

    摘要翻译： 集群的服务器计算机系统之间的通信会定期交换配置状态的通知，并根据需要发送更新的配置数据集。 每个状态消息标识服务器的本地配置的任何变化，并且还包括加密的验证数据。 每个服务器存储相应的配置数据，包括识别各个服务器已知的服务器参与集群的各组数据。 如接收到的每个状态消息正在针对由接收服务器存储的相应配置数据进行验证。 只有从接收服务器已知的从服务器发起的状态消息被确定为从接收服务器保持的配置数据确定的状态消息。 在经过验证的始发服务器识别更新的配置数据的情况下，接收服务器请求还必须经过验证的更新的配置数据集的副本等同地修改本地保存的配置数据。 因此，集群的配置会收敛于更新的配置。
