Using append only log format in data storage cluster with distributed zones for determining parity of reliability groups
Techniques for a data storage cluster and a method for maintaining and updating reliability data and reducing data communication between nodes, are disclosed herein. Each data object is written to a single data zone on a data node within the data storage cluster. Each data object includes one or more data chunks, and the data chunks of a data object are written to a data node in an append-only log format. When parity is determined for a reliability group including the data zone, there is no need to transmit data from other data nodes where the rest of data zones of the reliability group reside. Thus, inter-node data communication for determining reliability data is reduced. |

Selection of sponsored content using multiple sets of query terms
Multiple sets of words and phrases can be used as query terms for accessing sponsored content. Sponsored content is associated with item terms. The query terms are matched with the item terms. The result of the matching operation is a numerical score for each item of sponsored content that can be used to select sponsored content. Conditions present across the set of matched terms are detected. Such conditions can include the occurrence of a matched query term in multiple sets of query terms. This condition can be addressed by determining a number of unique matching query terms across all sets of query terms.

For example, the score could be adjusted according to a function of the number of unique matching query terms across all sets of query terms. If the number of matching query terms across all sets of query terms is low, such as one or two, then the function can define a penalty to be applied to the score given to the item of sponsored content. If the number of matching query terms across all sets of query terms is higher, such as three or more, then the function can define an adjustment to be applied to the score given to the item of sponsored content. |

Low dose single step grating based X-ray phase contrast imaging
Phase sensitive X-ray imaging methods provide substantially increased contrast over conventional absorption based imaging, and therefore new and otherwise inaccessible information. The use of gratings as optical elements in hard X-ray phase imaging overcomes some of the problems impairing the wider use of phase contrast in X-ray radiography and tomography. To separate the phase information from other contributions detected with a grating interferometer, a phase-stepping approach has been considered, which implies the acquisition of multiple radiographic projections. Here, an innovative, highly sensitive X-ray tomographic phase contrast imaging approach is presented based on grating interferometry, which extracts the phase contrast signal without the need of phase stepping. Compared to the existing phase step approach, the main advantage of this new method dubbed “reverse projection” is the significantly reduced delivered dose, without degradation of the image quality. |

Method of creating map alterations for use in a navigation device
An end-user can input a correction to a map error, directly on the device. The device is then able to use the correction without external processing of the correction. Hence, it is no longer necessary for an end-user to simply report errors to the map vendor over a web link, then wait for that map vendor to verify the error, update its maps and finally supply the end-user with updates—a cycle that can take months and sometimes years to complete. Instead, the navigation device can use the correction immediately. End-users can also share corrections with other end-users and also with a shared remote server that aggregates, validates and distributes correction. |

Varying the degree of precision in navigation data analysis
For a segment of a route, a navigation data gathering system and method may progressively increment the precision of data analysis in proportion to the number of people actively on a route segment.

Thus, the system and method may use navigation data related to a busy section of an interstate highway at the level of precision with which the data is gathered, but reduce the level of precision of data available for a rarely used road segment. |

Registration timer adjustment based on wireless network quality
The disclosure is directed to managing registration of a wireless communication device (WCD) operating in a wireless network. The WCD may support registration according to a signaling protocol, such as session initiation protocol (SIP). The WCD adjusts a registration timer based on network quality experienced by the WCD. When network quality is poor, for example, the WCD reduces the length of the registration timer. Reduced network quality may indicate that the WCD is at risk of losing network coverage. By reducing the length of the registration timer when network quality is degraded, stale registrations for out-of-coverage WCDs can be reduced. In particular, the shortened registration timer will expire more quickly, permitting the registration to be cleared more quickly. Consequently, the amount of call forwarding and other resources devoted to stale registrations can be reduced. If the WCD retains network coverage, it can maintain a registration by sending another registration request. |
