Efficient updating of journey instances detected within unstructured event data
Systems and methods are disclosed for efficiently storing information identifying journey instances within unstructured event data of a data intake and processing system. Each journey instance is illustratively associated with a series of events within the unstructured event data occurring over a journey duration.

Storage of instance data over time can require updating of prior incomplete journey instances with complete versions of such instance detected at a later point in time. However, a data store of the unstructured event data may be unsuited for such updating, as the store may maintain version information for deleted data to reduce possibility of data loss. To address this issue, a separate structured data store, such as a columnar time series data store, is provided to efficiently store instance information. |

Temperature locale sensors and related methods
Temperature locale sensors include an enclosure defining a sealed volume with a phase-change material therein at a known pressure. The phase-change material is formulated to exhibit a gas-to-solid phase change, without condensing to a liquid phase, at the known pressure and a targeted temperature, i.e., the material's “deposition temperature.” The phase-change material—while at least partially in gaseous form, either initially or after sublimation—is exposed to an environment with temperatures varying by location, including a maximum temperature above the phase-change material's deposition temperature and other temperatures at or below the deposition temperature. The gaseous phase-change material, in a location at the deposition temperature, solidifies from its gaseous phase to form solid grain deposits on a surface within the enclosure of the sensor. The solid deposits precisely identify the location of the specific, targeted deposition temperature. |

A process for producing ethylene and syngas comprising reacting, via OCM, first reactant mixture (CH4&O2) in first reaction zone comprising OCM catalyst to produce first product mixture comprising ethylene, ethane, hydrogen, CO2, CO, and unreacted methane; introducing second reactant mixture comprising first product mixture to second reaction zone excluding catalyst to produce second product mixture comprising ethylene, ethane, hydrogen, CO, CO2, and unreacted methane, wherein a common reactor comprises both the first and second reaction zones, wherein ethane of second reactant mixture undergoes cracking to ethylene, wherein CO2 of second reactant mixture undergoes hydrogenation to CO, and wherein an amount of ethylene in the second product mixture is greater than in the first product mixture; recovering methane stream, ethane stream, CO2 stream, ethylene stream, and syngas stream (CO&H2) from the second product mixture; and recycling the ethane stream and the carbon dioxide stream to second reaction zone. |

Process for forming sintered ceramic bodies having improved properties
A method is provided for making ceramic bodies having improved properties, such as optical and/or strength properties in which the ceramic bodies are densified by new sintering processes. The sintering profiles may have shorter run times than conventional sintering processes. Ceramic bodies made by these methods are suitable for use in dental applications, for example, as crowns. |
