Abstract: A transmitter can include a laser operable to output an optical signal; a digital signal processor operable to receive user data and provide electrical signals based on the data; and a modulator operable to modulate the optical signal to provide optical subcarriers based on the electrical signals. A first one of the subcarriers carriers carries first TDMA encoded information and second TDMA encoded information, such that the first TDMA encoded information is indicative of a first portion of the data and is carried by the first one of the subcarriers during a first time slot, and the second TDMA encoded information is indicative of a second portion of the data and is carried by the first one of the subcarriers during a second time slot. The first TDMA encoded information is associated with a first node remote from the transmitter and the second TDMA encoded information is associated with a second node remote from the transmitter.

Abstract: The present invention is directed to a method and system for enhancing the production of ammonia from gaseous hydrogen and nitrogen. Advantageously, the method and system does not emit carbon gases during production. The method and system enhances the production of ammonia compared to traditional Haber-Bosch reactions.

Abstract: A composition includes a plurality of processed leguminous straw particles having about 18-21 wt. % of particles on sieve #25 or particles measuring 0.71-1.17 mm and about 18-20 wt. % of particles on sieve #50 or particles measuring 0.3-0.7 mm, based on total weight of the leguminous straw particles, the composition being a mulch composition.

Abstract: An online system presents a user with a content item including an image and text. The online system overlays the text on the image if it predicts doing so will not render the text unreadable. To predict whether the overlay will render the text unreadable, the online system computes values describing various visual characteristics of a segment of the image on which the text may be overlaid and compares the values to corresponding threshold values. Based on the comparison, the online system predicts a readability of the text if overlaid on the segment. If the predicted readability is at least a threshold readability, the online system overlays the text on the segment of the image and presents the content item to the user with the text overlaid on the image. Otherwise, the online system presents the content item to the user with the text not overlaid on the image.

Abstract: An online system is configured to provide content items to users. The content item includes an image, and is displayed with a color block or colored border as an accent to the image. The color of the color block or colored bordered is dynamically selected based upon the image included in the content item, and is selected using a waterfall selection method comprising a sequence of different selection methods, each selection method configured to select a color based upon a most common color of the image that satisfies a respective set of selection criteria or determine that no color meets the respective set of selection criteria. The selection methods may comprise a dominant color selection method wherein the selected color corresponds to a most dominant color of the image, and a complementary color selection method wherein the select color is a complement of a dominant color of the image.
