Goal (sport) are required to hold the ball in. Similarly, in ice hockey, scoring a goal is similar to scoring a goal in football. The puck must be put completely over the goal line between the posts and under the bar either off an offensive player's stick or off any part of a defensive player's body. The puck may not be kicked, batted, or thrown into the goal, though a goal may be awarded if the puck is inadvertently deflected off an offensive player's skate or body into the goal. The goal structure is a frame tall and wide with a net
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
