In analog video, blanking occurs between horizontal lines and between frames. In raster scan equipment, an image is built up by scanning an electron beam from left to right across a screen to produce a visible trace of one scan line, reducing the brightness of the beam to zero (horizontal blanking), moving it back as fast as possible to the left of the screen at a slightly lower position (the next scan line), restoring the brightness, and continuing until all the lines have been displayed and the beam is at the bottom right of the screen. Its intensity is then reduced to zero again (vertical blanking), and it is rapidly moved to the top left to start again, creating the next frame

The mechanome[1] consists of the body, or ome, of data including cell and molecular processes relating to force and mechanical systems at molecular, cellular and tissue length scales - the fundamental "machine code" structures of the cell. The mechanome encompasses biological motors, like kinesin, myosin, RNAP, and Ribosome mechanical structures, like actin or the cytoskeleton and also proteomic and genomic components that are mechanosensitive and are involved in the response of cells to externally applied force. A definition of the "Mechanome" extending to cell/organ/body given by Prof

The overhand (or overhead) throw is a single-handed throw of a projectile where the object is thrown above the shoulder. The overhand throw is a complex motor skill that involves the entire body in a series of linked movements starting from the legs, progressing up through the pelvis and trunk, and culminating in a ballistic motion in the arm that propels a projectile forward. It is used almost exclusively in athletic events

Pedobarography is the study of pressure fields acting between the plantar surface of the foot and a supporting surface. Used most often for biomechanical analysis of gait and posture, pedobarography is employed in a wide range of applications including sports biomechanics and gait biometrics. The term 'pedobarography' is derived from the Latin: pedes, referring to the foot (as in: pedometer, pedestrian, etc

The physics of skiing refers to the analysis of the forces acting on a person while skiing. The motion of a skier is determined by the physical principles of the conservation of energy and the frictional forces acting on the body. For example, in downhill skiing, as the skier is accelerated down the hill by the force of gravity, their gravitational potential energy is converted to kinetic energy, the energy of motion

Several organisms are capable of rolling locomotion. However, true wheels and propellers—despite their utility in human vehicles—do not seem to play a significant role in the movement of living things (with the exception of certain flagella, which work like corkscrews). Biologists have offered several explanations for the apparent absence of biological wheels, and wheeled creatures have appeared often in speculative fiction

Sauropod neck posture is a subject occasionally debated among scientists, with some favoring postures closer to horizontal whilst others a more upright posture. Research has looked at various avenues of evidence and analysis including: attempting to reconstruct the neutral posture of their necks and estimating range of motion by studying the bones; attempting to reconstruct sauropod metabolism and the energy requirements of sustaining incredibly long necks in various postures; and comparing sauropod neck anatomy to those of living animals. Biomechanics The biomechanics of sauropod skeletons and necks can help determine at what angle the neck was positioned

In baseball, sidearm is a motion for throwing a ball along a low, approximately horizontal plane rather than a high, mostly vertical plane (overhand). Sidearm is a common way of throwing the ball in the infield, because many throws must be made hurriedly from the glove after fielding ground balls. An infielder's quickest throw to the bases is often from just above ground level, necessitating a horizontal release of the ball

Soft tissue is all the tissue in the body that is not hardened by the processes of ossification or calcification such as bones and teeth. Soft tissue connects, surrounds or supports internal organs and bones, and includes muscle, tendons, ligaments, fat, fibrous tissue, lymph and blood vessels, fasciae, and synovial membranes. It is sometimes defined by what it is not – such as "nonepithelial, extraskeletal mesenchyme exclusive of the reticuloendothelial system and glia"

In baseball, a submarine is a pitch in which the ball is released often just above the ground, but not underhanded, with the torso bent at a right angle, and shoulders tilted so severely that they rotate around a nearly horizontal axis. This is in stark contrast to the underhand softball pitch in which the torso remains upright, the shoulders are level, and the hips do not rotate. Description The "upside down" release of the submariner causes balls to move differently from pitches generated by other arm slots
