Fetching a query result using a query filter
A query scheme is presented in which a query filter data structure is created and utilized to determine whether to obtain live query data from a storage server or aged data within an associated dataset. The number of queries to the storage server may be reduced and overall efficiency of the query system is increased. Another query scheme is presented to adjust the frequency of a dataset refresh based upon a user defined data age parameter indication that is contained a subsequent query and/or based upon whether a frequency of storage server queries is above a predetermined threshold. The propensity of obtaining query results from a dataset is increased while the propensity of queries to the storage server decreases, thereby increasing query system efficiency. |

Generating a proactive alert for outdated scraping script
A method and system that proactively generate alerts for updating a scraping script to avoid scraping script errors. A predetermined number of webpages targeted by the scraping script are randomly sampled. The scraping script is appended to each webpage in the sample.

Scalable method of fabricating structured polymers for passive daytime radiative cooling and other applications
A switchable light transmission module is disclosed that includes a substrate having a first surface defining at least part of an enclosed volume, a porous layer disposed on the first surface and in fluid communication with the enclosed volume, and a reservoir in fluid communication with the enclosed volume.

Circular economy for plastic waste to polyethylene via refinery FCC feed pretreater and FCC units
Provided in one embodiment is a continuous process for converting waste plastic into recycle for polyethylene polymerization. The process comprises selecting waste plastics containing polyethylene and/or polypropylene, and passing the waste plastics through a pyrolysis reactor to thermally crack at least a portion of the polyolefin waste and produce a pyrolyzed effluent. The pyrolyzed effluent is separated into offgas, a pyrolysis oil and optionally pyrolysis wax comprising a naphtha/diesel fraction and heavy fraction, and char.
