Field hockey at the 1964 Summer Olympics Field hockey at the 1964 Summer Olympics Field hockey at the 1964 Summer Olympics was a sport open only to men. 15 teams played in the field hockey competition. The preliminary round was conducted by breaking the 15 teams into two groups of 7 and 8 teams. The groups then played a round-robin tournament with each team playing the other teams in the group once. 2 points were awarded for a win, 1 point for a tie, and 0 for a loss. The top two teams from each group advanced to the semifinals while the third and fourth played in
Wide-field multiphoton microscopy all the elements of the formula_4 tensor thanks to the capability of being able to change the polarisation of each beam independently. Wide-field multiphoton microscopy Wide-field multiphoton microscopy refers to an optical non-linear imaging technique tailored for ultrafast imaging in which a large area of the object is illuminated and imaged without the need for scanning. High intensities are required to induce non-linear optical processes such as two-photon fluorescence or second harmonic generation. In scanning multiphoton microscopes the high intensities are achieved by tightly focusing the light, and the image is obtained by stage- or beam-scanning the sample. In wide-field
