Leap-Frog (comics)
Leap-Frog is the name of several characters appearing in American comic books published by Marvel Comics. The first incarnation of Leap Frog, Vincent Patilio, first appeared in '' Daredevil'' #25 (February 1967). The second incarnation, Buford Lange, debuted in ''Daredevil'' (vol. 2) #16 (July 2001). The characters use a frog suit containing electrical coils on the soles of each of the two flippers which allow the wearer to leap great distances up to high or long. The boots' power source is worn on their backs like a backpack, and triggered via hidden buttons in their gloves. Additionally, the costume later had a strength-boosting exoskeleton, along with substantial internal padding and a computer-guided system for leaping accuracy. Publication history Vincent Patilio debuted in '' Daredevil'' #25-26 (February–March 1967), created by writer Stan Lee and artist Gene Colan. He later appeared in ''Daredevil Annual'' #1 (September 1967), ''The Defenders'' #64 (October 1978), ''Iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leap Frog (board Game)
Leap Frog, also known as Leapfrog, is a multi-player abstract strategy board game that was described by H.J.R. Murray in ''A History of Board Games Other Than Chess'' (1898) and attributes its origin to England. Several variants have been created (see Variants section) including one by Murray himself which utilizes different colored pieces with alternative point values. In the traditional game, players take any piece on the board and use it to hop over and capture other pieces. When no more pieces can be captured, the game ends, and the player with the most pieces is the winner. Murray includes it in the section called Clearance Games which has the game Solitaire. It resembles Solitaire in many ways except that Solitaire is typically only played by one person. Murray never stated that the moves are limited to orthogonal directions. The game might still work with diagonal moves. Setup A rectangular board with 15 to 18 squares in length on each side is used. The pieces in the t ...

Leapfrog Appeal
In legal procedure, a leapfrog appeal is a special and relatively rare form of appeal in which a case is appealed directly from a lower court to a higher court, skipping an intermediate appellate court. For example, in England & Wales, an appeal from the High Court to the Supreme Court, thereby skipping the Court of Appeal. England & Wales A leapfrog appeal may be brought from the High Court to the Supreme Court (or previously the House of Lords), thereby skipping the Court of Appeal. The procedure is governed by Part II of the Administration of Justice Act 1969 as amended. In summary, if the High Court judge considers that the relevant conditions are met, and that the case is suitable for a leapfrog appeal, then they may grant a certificate to that effect (section 12(1) of the Act). If a certificate is granted, any of the parties to the proceedings may apply to the Supreme Court for leave to make a leapfrog appeal, which if granted enables the leapfrog appeal to take place ...

Leapfrogging
Leapfrogging is a concept used in many domains of the economics and business fields, and was originally developed in the area of industrial organization and economic growth. The main idea behind the concept of leapfrogging is that small and incremental innovations lead a dominant firm to stay ahead. However, sometimes, radical innovations will permit new firms to leapfrog the ancient and dominant firm. The phenomenon can occur to firms but also to leadership of countries or cities, where a developing country can skip stages of the path taken by industrial nations, enabling them to catch up sooner, particularly in terms of economic growth. Industrial organization In the field of industrial organization (IO), the main work on leapfrogging was developed by Fudenberg, Gilbert, Stiglitz and Tirole (1983). In their article, they analyze under which conditions a new entrant can leapfrog an established firm. That leapfrogging can arise because an established monopolist has a somewhat re ...

Leapfrogging (infantry)
Bounding overwatch (also known as leapfrogging, moving overwatch, or the buddy system) is a military tactic of alternating movement of coordinated units to allow, if necessary, suppressive fire in support of offensive forward "fire and movement" or defensive " center peel" disengagement. As members of a unit (element to platoon level) take an overwatch posture, other members advance to cover; these two groups continually switch roles as they close with the enemy. This process may be done by "leapfrogging" with fireteams, but is usually done within fireteams along a squad/platoon battle line to simulate an overwhelming movement towards the enemy and make it more difficult for the enemy to distinguish specific targets. This military tactic takes continuous training and focused coordination to be effectively practiced on the modern battlefield. It was first developed in World War II, when the prevalence of man-portable automatic weapons made suppressing fire possible. Example of ...

Leapfrogging (strategy)
Leapfrogging was an amphibious military strategy employed by the Allies in the Pacific War against the Empire of Japan during World War II. The key idea was to bypass heavily fortified enemy islands instead of trying to capture every island in sequence en route to a final target. The reasoning was that those heavily fortified islands could simply be cut off from their supply chains (leading to their eventual capitulation) rather than needing to be overwhelmed by superior force, thus speeding up progress and reducing losses of troops and material. The strategy did not prove entirely successful, as many Japanese garrisons survived longer than the Allies expected. History Background As the 20th century dawned, the U.S. had several interests in the western Pacific to defend; namely, access to the Chinese market and its colonies – the Philippines and Guam – which the U.S. had gained as a result of the 1898 Spanish–American War. After Japan's victories in the Sino-Japane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LeapFrog Enterprises
LeapFrog Enterprises, Inc. is an educational entertainment and electronics company based in Emeryville, California. LeapFrog designs, develops, and markets technology-based learning products and related content for the education of children from infancy through grade school. The company was founded by Michael Wood and Robert Lally in 1994. John Barbour is the chief executive officer of LeapFrog. History 1990–1997: Founding The history of LeapFrog traces back to the late 1980s when LeapFrog founder Michael Wood, an attorney at Cooley LLP, had difficulties teaching his son how to read. He began researching phonics and marketing while continuing as a partner at Cooley. By 1994, Wood had developed the first prototype of what would become Phonics Desk, LeapFrog's first product. The prototype utilized a Texas Instruments chip that was previously used by one of Wood's clients to develop talking greeting cards. Wood solicited feedback on his prototype from the late Robert Calf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leapfrog Group
A patient safety organization (PSO) is an organization that seeks to improve medical care by advocating for the reduction of medical errors. Common functions of patient safety organizations include health care data collection, reporting and analysis on health care outcomes, educating providers and patients, raising funds to improve health care, and advocating for safety-oriented policy changes. In the United States, the term typically refers only to PSOs that have been formally recognized by the Secretary of Health and Human Services and listed with the Agency for Healthcare Research and Quality. A federally-designated PSO differs from a typical PSO in that it provides health care providers in the U.S. privilege and confidentiality protections in exchange for efforts to improve patient safety. In the 1990s, reports in several countries revealed a staggering number of patient injuries and deaths each year due to avoidable errors and deficiencies in health care, among them ad ...

Leapfrog Integration
In numerical analysis, leapfrog integration is a method for numerically integrating differential equations of the form \ddot x = \frac = A(x), or equivalently of the form \dot v = \frac = A(x), \qquad \dot x = \frac = v, particularly in the case of a dynamical system of classical mechanics. The method is known by different names in different disciplines. In particular, it is similar to the velocity Verlet method, which is a variant of Verlet integration. Leapfrog integration is equivalent to updating positions x(t) and velocities v(t)=\dot x(t) at different interleaved time points, staggered in such a way that they "leapfrog" over each other. Leapfrog integration is a second-order method, in contrast to Euler integration, which is only first-order, yet requires the same number of function evaluations per step. Unlike Euler integration, it is stable for oscillatory motion, as long as the time-step \Delta t is constant, and \Delta t < 2/\omega. Using Yoshida coefficien ...
