    摘要： Data is received characterizing an electrocardiogram (ECG) measured from a patient having a pacemaker. The pacemaker can intermittently provide a pace to a heart of the patient. By comparing at least a portion of the received data to a template a pace pulse can be detected from at least a portion of the received data. The template comprises one or more pace pulses measured from the patient. The template is modified, at least in part, by the detected pace pulse to update the template. Data characterizing the detected pace pulse is provided. Related apparatus, systems, techniques and articles are also described.

    摘要： The disclosure generally describes computer-implemented methods, software, and systems for rating and ranking stakeholders in the distribution of controlled substances. One computer-implemented method includes receiving, at a computer system, retail prescription data, encrypted patient data, reference prescriber data, and pharmaceutical purchase data. For a retail outlet included in the received data, the method includes aggregating the received data and determining information about sales of a pharmaceutical product associated with the retail outlet. The method further includes rating the retail outlet based on the aggregated information.

    摘要： In an embodiment of the invention, there is proposed a method of and apparatus for accessing in a user equipment, the method including the steps of: i) performing a random access on a predetermined resource according to a channel condition of the user equipment, wherein the predetermined resource is associated with the channel condition of the user equipment; and ii) receiving, on a PDCCH, a response to the random access from an eNB. With this solution, during a random access of a user equipment, particularly a MTC device, an eNB can perform a Random Access Response (RAR) adaptively using a different number of Control Channel Elements (CCEs) according to an indication, capable of reflecting a channel condition, e.g., a signal to noise ratio, of the user equipment, thereby saving the channel resource.

    摘要： The object of the present invention is to provide a method and an apparatus for performing synchronization among neighboring base stations in the wireless communication network. According to the technical solution of the present invention, a base station turns off a transmitter randomly to receive a synchronization signal from neighboring base stations, and obtains a new local synchronization reference time based on the synchronization reference time of other neighboring base station. With the apparatus and the method provided by the present invention, the strongly robust synchronization among base stations is realized.

    摘要： In recent years, researchers have found that some XOR erasure codes lead to higher performance and better throughput in fault-tolerant distributed data storage applications. However, little consideration has been given to the advantages of parallel processing or hardware implementations taking advantage of the emergence of multi-core processors. An efficient horizontal MDS-like (Maximum Distance Separable) RAID-6 scheme, called EEO, is provided which significantly improves the performance of the decoding procedure in parallel implementations with little storage overhead. EEO is the fastest and most efficient double disk failure recovering algorithm in RAID-6, at the cost of only two more parity symbols. In practice, it is very useful for application where high decoding throughput is desired.

    摘要翻译： 近年来，研究人员发现，一些异或擦除码导致容错分布式数据存储应用中的更高的性能和更好的吞吐量。 然而，很少考虑到利用多核处理器出现的并行处理或硬件实现的优点。 提供了一种称为EEO的高效的横向MDS（最大距离可分离）RAID-6方案，其显着地提高了并行实现中的解码过程的性能，同时具有很少的存储开销。 EEO是RAID-6中最快，最有效的双磁盘故障恢复算法，只有两个奇偶校验符号。 实际上，对于需要高解码吞吐量的应用来说，这是非常有用的。
