One day in the 1980’s I was helping a visiting scientist get his experiment set up at a remote site to the west of Ottawa. This site contained the decaying remains of decades of radio experiments. Among some trees I found an old shed, crammed to the roof with yagi antennas, combiners, hybrids and many matched lengths of heliax coaxial cable. Many were broken, but mixed in with the debris were s...
A graph is planar if it can be drawn in the plane without edges crossing. More formally, a graph is planar if it has an embedding in the plane, in which each vertex is mapped to a distinct point P (v), and edge (u, v) to simple curves connecting P (u), P (v), such that curves intersect only at their endpoints. Examples of planar graphs: Pn, Trees, Cycles, X-tree, K4. Examples of non-planar grap...

PURPOSE To investigate whether the induction of cytotoxic T lymphocytes (CTLs) targeting VEGF receptor 2 inhibits corneal neovascularization caused by alkali injury. METHODS H-2Db-restricted peptide corresponding to amino acids 400 to 408 of VEGF receptor 2 (VEGFR2(400-408)) was used as an epitope peptide. Dendritic cells (DCs) were harvested from bone marrow progenitors of C57BL/6 mice. Six-...
We present images of the SNR HB3 at both 408 MHz and 1420 MHz from the Canadian Galactic Plane Survey mainly based on data from the Synthesis Telescope of the Dominion Radio Astrophysical Observatory. We reproduce the 100m-Effelsberg HB3 image at 2695 MHz at large scale, and find that there exists a background emission gradient across the HB3 area. Based on our analysis of background emission a...
