Abstract: A method for extracting photon depth-of-interaction of an incident photon in a crystal with a reflective coating optically coupled to all sides of the crystal, except for an opening, wherein a photodetector is optically coupled to the opening. A pulse shape of a photodetector output as a result of detection of scintillation photons from the crystal generated by the incident photon is measured, wherein the reflective coating optically coupled to all sides of the crystal, except for an opening optically coupled to the photodetector reflects the scintillation photons passing to all sides of the crystal, except for the opening optically coupled to the photodetector. The pulse shape is used to determine photon depth-of-interaction within the crystal.

Abstract: There are provided systems and methods for allocation of digital media over communication networks. A bidding platform for digital advertising manages multichannel buying of digital media using impression-level decisioning based on multiple parameters and data sources. When a request for an ad is received from a publisher or other supply side entity, such as an ad exchange or supply side platform, an expected value of the advertisement impression to each advertiser is calculated, in some cases, in real time, on behalf of the advertiser using media-buying rules. An ad having a highest expected value is selected, and the bidding platform responds to the ad request with a bid and the selected ad, and serves the winning ad if bid response wins the publisher side auction, resulting in an ad impression for the winning ad. User interactions with the ad are recorded and leveraged to optimize further the media buying rules.

Abstract: An adjustable roller leg assembly, in a first embodiment, has a mounting cylinder, a housing cylinder, a bearing assembly, and a bearing engagement cylinder. The bearing assembly has a stem affixed to the housing cylinder, leaving the bearing protruding beyond the housing cylinder end. The bearing engagement cylinder is threadably inserted into the housing cylinder, which is threadably inserted into the mounting cylinder. The adjustable roller leg assembly is then attached to an article. Article movement occurs by rotation of the bearing engagement cylinder to engage the bearing against the housing, so that the bearing protrudes beyond the open end of the bearing engagement cylinder and contacts the floor. Stationary support is achieved by counter-rotating the bearing engagement cylinder until the bearing is completely contained therein, so that the bearing engagement cylinder contacts the floor. Article height adjustment is by housing cylinder rotation relative to the mounting plate cylinder.
