Abstract: A computer system generates a first rating of a research paper by applying one or more trained machine learning models to data extracted from the research paper. As one or more users interact with the research paper, the computer system detects actions by the user that are directed to the research paper. The computer system modifies the one or more machine learning models using the actions by the users. A second rating of the research paper is generated by applying the modified models to the actions by the users and the first rating of the research paper.

Abstract: A collaboration platform facilitates review of research papers by recommending papers to reviewers and managing annotation of the papers by the reviewers. The platform applies a model to analyze historical actions by a user with respect to the platform to predict an attribute of the user. Based on a match between the predicted attribute and the subject matter of a paper, the platform recommends at least one research paper to the user. As the user reads the paper, the platform receives an input from the user to define an annotation associated with the research paper. The user attribute is linked to the annotation and the annotation is published in association with the research paper, where the annotation is selected for display to a second user based at least in part on the attribute of the user.

Abstract: A revolver for firing high velocity ammunition includes a frame, a cylinder, a barrel, and a firing mechanism. The revolver may include one or more of the following, each of which is especially adapted for use in the context of firing high velocity ammunition: spacers for adjusting a barrel-cylinder gap, for eliminating broaching of the rearward surface(s) of the barrel; a forcing cone formed in the rearward opening of the barrel for accommodating deformed projectiles; a reflective surface (e.g., mirrored surface) provided on the cone and/or barrel rearward surfaces, for reducing erosion resulting from using high velocity ammunition; gain-twist rifling in the barrel for a smoother transition to full projectile velocity; a larger diameter, hardened firing pin bushing for minimizing brass flow in the rearward direction; and a front sight assembly that minimizes lateral shift or drift of the sight pin during firing.

Abstract: The Green Coffee Exchange is an Internet auction trading platform for “industrial level” trading of green coffee beans for the coffee industry. The Green Coffee Exchange opens up the limited, narrow green coffee trading marketplace that exists today into a global marketplace for professional buyers and sellers of green coffee beans. This invention provides the capabilities for “coffee farmers” (growers) and the “coffee buyers” to trade directly with each other. The Green Coffee Exchange eliminates the additional layers of middlemen and their exorbinate mark-ups in both the coffee growing countries and the coffee consuming (importing) countries. Ex. USA. Also, this invention creates logistical efficiencies by streamlining the international green coffee supply-chain; which generates storage and transportation synergies that will allow “coffee farmers” and the “coffee buyers” to substantially increase their profitability.
