Ratlines, pronounced "rattlin's", are lengths of thin line tied between the shrouds of a sailing ship to form a ladder. Found on all square rigged ships, whose crews must go aloft to stow the square sails, they appear on larger fore-and-aft rigged vessels to aid in repairs aloft or conduct a lookout from above. Lower courses in a ratline are made of slats of wood for support where the distance between shrouds is greatest; these wooden boards are called rat-boards. In some instances holes in these slats guide and organise low-tension lines between the deck and the rig. Although the name clove hitch is given by Falconer in his Dictionary of 1769, the knot is much older, having been tied in ratlines at least as early as the first quarter of the sixteenth century; this is shown in early sculpture and paintings.

Rampart (video game)

Rampart is an arcade game, released in 1990 by Atari Games, that combines the shoot'em up and puzzle genres. It was first made available as an arcade game but was subsequently offered for a number of home gaming platforms; the game is considered a precursor to the tower defense genre. In Rampart, the player is in control of a set of castles, which they must defend, by alternately shooting at attacking ships, repairing any damage done to them within a time limit. Surrounding this castle is a wall, made up of small blocks surrounding a region of the board; this area is considered the player's territory, it may contain one or more castles, any number of cannons. The maintenance of this territory is the primary focus of the game. Once the player defeats the opponent, the player can execute the commander, by walking the plank or beheading; the single-player game consists of six levels. The ultimate aim is to destroy a fleet of attacking ships while repairing any damage the fort sustains. At the start of each level, the player chooses the location of their fort from a number of options.

This location is surrounded by a wall to form a castle, which the player can place cannons within. After this, an attacking round commences, followed by a repair round, where any damage to the castle must be repaired. If the player manages to survive the repair phase, they are given a short amount of time to place additional cannons within the walls of his fort, after which the battle resumes; this cycle continues until either the player fails a repair round, or enough ships in the enemy's fleet are sunk. When the opposing navy has been sufficiently depleted, the level is won, the player may choose another level from the island map. After starting a new game or after a successful repair round, the player may gain extra cannons to be placed in their territory. In the SNES and PC versions only, the cannons gained can be converted into powerups: The Balloon floats at the beginning of phase 1 to the most powerful enemy ship or cannon and converts it to the player side for the successive fighting round.

The Supercannon is bigger than the usual cannons and fire red projectiles, which sink any ship in one hit or leave a permanent fire if they hit the landscape In an attacking round, the player and enemy ships fire at each other using their respective cannons. The player can sink the enemy ships. Enemy ships move around while they fire, making it necessary to lead your target like in Missile Command. Ships come in three types: Single-sailed ships shoot at your walls and move around, but do little else, it takes two shots to sink one. Double-sailed ships require three hits to sink, if they reach the shore they deposit grunts, small tank-like objects that multiply and move around during the repair phase, they can be shot with cannons and destroyed by surrounding them with walls, but they tend to get in the way and are capable of destroying castles if left unchecked. Grunts adjacent to walls during battle can destroy them to get inside a player's area. Red ships require 5 hits to sink, their shots leave fiery craters whenever they strike a wall.

These craters must be built around during the repair phase, each persists for three rounds. Levels feature "dark" versions of each of these ships, which are each capable of taking one additional hit before sinking. In the repair round, the player must repair the damage done to the wall surrounding their territory, they are presented with a random series of polyomino shapes, must place them on the island within a time limit to keep their castles surrounded by walls. While superficially similar to Tetris shapes, these pieces have much greater variety, ranging from 1 by 1 squares that can fit anywhere to big plus and U-shapes; the pieces do not fall, but may be moved around the screen and placed in any spot but they cannot be placed on top of existing objects. Pieces cannot be passed, they must be placed down before getting the next one. At the start of the Repair phase, any territory, not surrounded by a complete, unbroken wall is lost. By placing wall pieces, the player attempts to "capture" territory by completing a wall around it.

Before the timer expires, the player must have completed a wall around at least one castle to survive the round and continue playing. It is advantageous to capture previously-placed cannons, as only cannons within the player's territory may be used in the subsequent battle phase; when playing with two or three players the game is similar, except that instead of fighting against enemy ships, the players each have their own area of land separated by a river, they shoot at each other's walls. In multiplayer mode, cannons can be destroyed if they take enough hits, there are bonus squares that are worth extra points when captured, there are no grunts or craters, but the game is otherwise similar. Players shoot at each other's walls during the Battle phase and try to make it difficult for them to survive the next repair round. If a player is unable to repair his wall, he must insert another credit to remain in the game, but cannot do so more than three times; the last player remaining is the winner.

If all the players remain in the game for an operator-adjustable number of rounds, they engage in a "Final Battle" at the start of the

ACE model

The ACE model is a statistical model used to analyze the results of twin studies. It aims to decompose sources of phenotypic variation into three categories: additive genetic variance, common environmental factors, specific environmental factors plus measurement error, it is used in genetic epidemiology and behavioural genetics. The basic ACE model relies on several assumptions, including the absence of assortative mating, that there is no genetic dominance or epistasis, that all genetic effects are additive, the absence of gene-environment interactions. In order to address these limitations, several variants of the ACE model have been developed, including an ACE-β model, which emphasizes the identification of causal effects, the ACDE model, which accounts for the presence of dominant genetic effects.

Canyon High School (Anaheim, California)

Canyon High School is a traditional four-year high school located in the Anaheim Hills community in the city of Anaheim, California and is an International Baccalaureate school. It is located on 40 acres of land on Imperial Highway between the cross streets of Santa Ana Canyon Road and Nohl Ranch Road, serves students in the Orange Unified School District; the school, which opened its doors in 1973, has a student population of 2,400. The school serves the community of Anaheim Hills as well as parts of East Anaheim and Orange, was designated a California Distinguished School in 2007 by the California Department of Education; the school's fight song is Lee Swing. The school is ranked as one of the top 1,000 high schools in the United States by Newsweek at number 128, a distinction given to less than 1% of high schools nationally, it is the 204th highest ranked school in the state of California. The school started in 1974 as a shared campus with the established Villa Park High School for students in grades 10-12.

Upon completion of the Anaheim Hills campus, a variety of names were considered for the site. A ballot of three proposed names was given to the students of Vista Del Rio Jr. High School to vote on; the students did not like any of the choices. Canyon High School was the name of choice due to its location and the fact that the local students call that area "The Canyon"; the name Canyon High School was selected. Boundary changes in the district and an increase in the population of the Anaheim Hills community resulted in changes at the school; the school was designated to serve students in grades 9 through 12 in 1987, El Rancho Charter School was designated as the only feeder school within the boundaries of Canyon High School. The school implemented an International Baccalaureate Program in 1988. Canyon High School offers a variety of programs for its students including the International Baccalaureate Program, Stellar Technology Program, Specialized Science Program, in addition to numerous college-level Advanced Placement and Honors courses.

Its current API Score is 861, designating the school in the top 10% of all high schools in the state of California. The school focuses on technology, having undergone thousands of dollars worth of upgrading the schools technology, by adding 100 computers, making 19 of its courses available as online classes. In 2019, the U. S. News & World Report ranked the school 387th in the state of California and 2,557th in the United States; the school mascot is a Comanche. Students at Canyon High School compete in the following sports: David Buehler, National Football League kicker Sam Didier, Art Director for Blizzard Entertainment Eden Espinosa, singer/stage actress Seonna Hong, artist Courtney Mathewson, Olympic gold medalist water polo player Omar Benson Miller, actor Connie Needham, actress Brian Nestande, California State Assemblyman Andy Park, Illustrator Craig Ritter, Houston Oilers lineman Chris Snitko, Major League Soccer player James Storm, actor/wrestler Kwame Watson-Siriboe, Major League Soccer player John Cummings, pitcher Rob Deer, All-Star right fielder Grant Green, second baseman Doug Linton, pitcher Vinnie Pestano, pitcher Steve Scarsone, second baseman Eric Valent, first baseman Christian Colon, shortstop Canyon High School website
