Abstract: A screw includes a shank extending axially from a head and thread convolutions spirally disposed on the shank. The head has a top surface, a conical surface opposite to the top surface, cutting units extending circumferentially of the top surface, accommodation portions recessedly provided in the conical surface, and ridge portions each located between every two adjacent accommodation portions. The accommodation portions and the ridge portions extend between the cutting units and the shank. Accordingly, the cutting units sever fibers and scrape burrs which incur a ragged edge of a workpiece, thereby preventing the entanglement of unsevered fibers. The ridge portions cut fibers into chips and guide chips to the accommodation portions for suitable accommodation of chips inside the accommodation portions, which attains a tight engagement between the screw and the workpiece, reduces screwing resistance, and allows the top surface to fit level with a surface of the workpiece.

Abstract: An online system manages presentation of content items in various presentation contexts such as when the users are browsing pages or when the users have entered a search query. The online system trains a single unified machine learning model that predicts one or more likelihoods of a target event associated with presentation of a content item in the different presentation contexts. The learned model is applied to a set of candidate content items associated with a presentation opportunity in a specific context. Features that are inapplicable to the specific context may be masked when applying the model. The online system may select between the candidate content items based on the predicted likelihoods using the model trained across the multiple different contexts, such that the prediction for one context may be based in part on learned outcomes in other related contexts.
