The electric pretensioners also can operate on a repeated or sustained basis, providing better protection in the event of an extended rollover or a multiple collision accident.

Dislocation loops may form in the damage created by energetic irradiation. A prismatic dislocation loop can be understood as an extra (or missing) collapsed disk of atoms, and can form when interstitial atoms or vacancies cluster together. This may happen directly as a result of single or multiple collision cascades, which results in locally high densities of interstitial atoms and vacancies. In most metals, prismatic dislocation loops are the energetically most preferred clusters of self- interstitial atoms.

Chipmunk supports multiple collision primitives attached to one rigid body, and bodies may be joined by constraints. It has a flexible collision detection system with layers, exclusion groups and collision callbacks. Callbacks are defined based on user definable "collision types" and may reject collisions and even override the calculation of friction and elasticity coefficients. Version 7 of the library introduced "Autogeometry", an image tracing feature that transforms a raster graphic into a polygonal shape usable by the library.

Some recent incidents are listed below: May 24, 2014: Five motorcyclists were injured when performing stunts in the "Globe of Death", during a function in Circus Rhodes in Argentina. They were injured when the roof of the globe burst, sparking a multiple collision. One of the riders suffered a broken clavicle and others had burns and minor injuries from the motorcycles. May 25, 2015: Two motorcycle riders crashed in midair while performing the stunt at Uncle Sam's Great American Circus in Chantry Park, Ipswich, England.

The METLIN Metabolite and Chemical Entity Database is the largest repository of experimental tandem mass spectrometry data acquired from standards. The tandem mass spectrometry data on over 850,000 molecular standards () is provided to facilitate the identification of chemical entities from tandem mass spectrometry experiments. In addition to the identification of known molecules it is also useful for identifying unknowns using its similarity searching technology. All tandem mass spectrometry data comes from the experimental analysis of standards at multiple collision energies and in both positive and negative ionization modes.

From the early 2000s to the present, the Siuzdak lab created and has been expanding the tandem mass spectrometry database known as METLIN. METLIN is made up solely of experimental data generated from high resolution tandem mass spectrometry instrumentation, all of the data is derived from molecular standards. METLIN now has over 850,000 molecular standards with experimental tandem mass spectrometry data. METLIN is unique with respect to its size, as other databases are over an order of magnitude smaller, and it is also unique because all of METLIN's tandem mass spectrometry data has been systematically generated at multiple collision energies and in positive and negative ionization modes.

Keegan was replaced by Italian driver Gimax for Italy who failed to qualify and Brambilla retired after he, James Hunt, Riccardo Patrese, Ronnie Peterson, Hans-Joachim Stuck, Patrick Depailler, Didier Pironi, Derek Daly, Clay Regazzoni and Brett Lunger were all involved in an accident before the first corner. Brambilla suffered serious head injuries when he was hit by a flying wheel during the multiple collision on the opening lap but survived. Brambilla was replaced by Italian Beppe Gabbiani and Gimax was replaced by Frenchman René Arnoux for the final two races. For the United States Grand Prix East Gabbiani failed to qualify and Arounx finished ninth.

On 24 January 2012 it was announced that d'Ambrosio would act as reserve driver for Lotus F1 ahead of the 2012 season and be present at all of the season's races along with drivers Kimi Räikkönen and Romain Grosjean. He also did co-commentary work for Sky Sports F1 for F1 practice sessions, GP2 and GP3 races and for Belgian French-speaking channel RTBF for F1 races. D'Ambrosio made his race début for Lotus at the 2012 Italian Grand Prix; he replaced Grosjean, who was banned for one race for causing a multiple collision at the previous round in Belgium. He qualified in 16th place, and started in 15th place due to a 10-place grid drop penalty applied to Pastor Maldonado.

It is easy now to attack me and I guess everyone will, but I am OK with that." On 5 May, Red Bull announced that they had relegated Kvyat back to their junior squad, Toro Rosso, the team for which he made his début in , for the remainder of the season, switching him with 18-year-old Max Verstappen. Red Bull's team principal Christian Horner explained the driver swap with Verstappen's talent, also stressing that the move to Red Bull would tie him to the team for the foreseeable future. Following multiple collision shortly after the start, Jenson Button pressed for changes to be made to turn two of the Sochi Autodrom, saying: "The bollard at turn two is the problem at the start because people are trying to fight through turns two and three.

In 1995 liquid chromatography mass spectrometry metabolomics experiments were performed by Gary Siuzdak while working with Richard Lerner (then president of The Scripps Research Institute) and Benjamin Cravatt, to analyze the cerebral spinal fluid from sleep deprived animals. One molecule of particular interest, oleamide, was observed and later shown to have sleep inducing properties. This work is one of the earliest such experiments combining liquid chromatography and mass spectrometry in metabolomics. In 2005, the first metabolomics tandem mass spectrometry database, METLIN, for characterizing human metabolites was developed in the Siuzdak laboratory at The Scripps Research Institute. METLIN has since grown and as of July 1, 2019, METLIN contains over 450,000 metabolites and other chemical entities, each compound having experimental tandem mass spectrometry data generated from molecular standards at multiple collision energies and in positive and negative ionization modes.

As was traditional in Monaco, the race began at the relatively late time of 15:30, allowing Prince Rainier and his family to eat lunch before viewing the event from the royal box on the start-finish straight. The race took place in warm, sunny conditions, with an ambient temperature of , and was watched by a total of approximately 48,000 spectators. As the drivers completed their reconnaissance laps from the pit-lane to the starting grid, an oil leak was discovered on Frentzen's Sauber, so he switched to the newly built spare car in time for the start. As the green light signalled the start of the race, Hill and Schumacher both made brisk starts and led into Sainte Dévote, but behind them a multiple collision between Coulthard and the two Ferraris caused the race to be red-flagged to a halt.

The 1998 Belgian Grand Prix (formally the LVI Foster's Belgian Grand Prix) was a Formula One motor race held on 30 August 1998, at Circuit de Spa- Francorchamps; contested over 44 laps, it was the thirteenth race of the 1998 FIA Formula One World Championship. The race was won by Damon Hill driving for the Jordan team, with Hill's teammate Ralf Schumacher finishing in second place and Jean Alesi finishing in third for the Sauber team, taking his last podium of his F1 career. The race ran entirely in extremely wet weather, and on the first lap David Coulthard lost control of his McLaren, causing a multiple collision involving thirteen drivers, which led to the race being stopped. After a delay of more than an hour to clear the track, a second attempt was made to start the race, albeit without four of the drivers involved in the incident.
