This report covers the 44th annual Group of 7 (G-7) summit on June 8-9. Seven of the world's largest advanced economies meet annually to discuss and coordinate economic and foreign policies, with the 2018 agenda focusing on economic growth, gender equality, jobs, and the environment.

This report presents an overview of Canada's political situation, foreign and security policy, and economic and trade policy, focusing particularly on issues that may be relevant to U.S. policymakers.

This report discusses the NAFTA renegotiation process and major topics of interest in the agreement as well as Congress's role in the negotiation and approval process.

This report discusses current issues and developments in "Lumber V", a dispute between Canada and the U.S. over the pricing and quantity of softwood lumber imports from Canada to the U.S., which has been a source of friction between the two countries for decades.

Discrimination of different tree crowns based on their 3D shapes is essential for a wide range of forestry applications, and, due to its complexity, is a significant challenge. This study presents a modified 3D shape descriptor for the perception of different tree crown shapes in discrete-return LiDAR point clouds. The proposed methodology comprises of five main components, including definition of a local coordinate system, learning salient points, generation of simulated LiDAR point clouds with geometrical shapes, shape signature generation (from simulated LiDAR points as reference shape signature and actual LiDAR point clouds as evaluated shape signature), and finally, similarity assessment of shape signatures in order to extract the shape of a real tree. The first component represents a proposed strategy to define a local coordinate system relating to each tree to normalize 3D point clouds. In the second component, a learning approach is used to categorize all 3D point clouds into two ranks to identify interesting or salient points on each tree. The third component discusses generation of simulated LiDAR point clouds for two geometrical shapes, including a hemisphere and a half-ellipsoid. Then, the operator extracts 3D LiDAR point clouds of actual trees, either deciduous or evergreen. In the fourth …
