Abstract: A signal generator includes a data source, a power source, and a modulator. The modulator is configured to modulate a power signal from the power source with a data signal from the data source to generate a modulated power signal. Data values of the data signal correspond to variations in a voltage level of the modulated power signal over time. The modulator is coupled to output the modulated data signal to a one-wire interface.

Abstract: A system and a method are disclosed for recommending podcasts. In an embodiment, the system detects a podcast request, and responsively determines whether a profile of the user indicates consumption by the user of podcasts. Responsive to determining that the profile does not indicate consumption by the user of podcasts, the system determines music preferences of the user based on data of the profile, and generates a podcast seed based on the music preferences. The system selects a podcast recommendation based on the podcast seed, and provides the podcast recommendation to the user. The system receives a selection of the podcast recommendation by the user, and responsively plays back a podcast corresponding to the podcast recommendation.

Abstract: Methods of synthesizing transition metal dichalcogenide nanoparticles include forming a metal-amine complex, combining the metal-amine complex with a chalcogen source in at least one solvent to form a solution, heating the solution to a first temperature for a first period of time, and heating the solution to a second temperature that is higher than the first temperature for a second period of time.

Abstract: Quantum dot semiconductor nanoparticle compositions that incorporate ions such as zinc, aluminum, calcium, or magnesium into the quantum dot core have been found to be more stable to Ostwald ripening. A core-shell quantum dot may have a core of a semiconductor material that includes indium, magnesium, and phosphorus ions. Ions such as zinc, calcium, and/or aluminum may be included in addition to, or in place of, magnesium. The core may further include other ions, such as selenium, and/or sulfur. The core may be coated with one (or more) shells of semiconductor material. Example shell semiconductor materials include semiconductors containing zinc, sulfur, selenium, iron and/or oxygen ions.
