Abstract: In embodiment, a method of displaying an answer of a question-answer pair in response to a natural language search query includes receiving, from a Bidirectional Encoder Representations from Transformers (BERT) model, an array of attention matrices for the question-answer pair, where each attention matrix of the array of attention matrices includes an array of attribution values, generating a total attribution value for each word of an answer of the question-answer pair from the array of attention matrices, and displaying the answer on an electronic display, wherein one or more words of the answer is highlighted based on the total attribution values for each word.

Abstract: A modular product display unit includes a tray and display inserts. The tray includes a magnetic top surface and an apron at least partially surrounding the magnetic top surface and extending above the magnetic top surface. The display inserts are disposed on and magnetically coupled to the magnetic top surface, the display inserts form product-display compartments on the magnetic top surface.

Abstract: Systems disclosed herein are directed to a display fixture having a display surface, dynamic input blocks disposed along the display surface, and a display screen positioned on the display surface next to the dynamic input blocks. Each of the dynamic input blocks displays content associated with a product. In response to a user interaction with one of the dynamic input blocks, the display screen displays content related to the product associated with the one dynamic input block. The content and associated products displayed on the dynamic input blocks automatically change in response to an external input.

Abstract: Provided are systems and methods for treating wastewater with a continuous-process mobile station. The mobile station may include one or more mobile units configured to receive a feed of wastewater. The one or more mobile units may include: a mobile ozonation unit configured to treat the received feed of wastewater with ozone gas to breakdown impurities in the wastewater, a pH control unit may be configured to raise pH of the treated wastewater, a mobile electrocoagulation unit configured to separate solids and metals from the treated wastewater, a mobile flocculation unit configured to cause suspended particles to form flocs and to remove the flocs from the received treated water.
