Molecular simulations are a powerful tool and they have provided predictions in a wide variety of physical and chemical systems that have later been verified by experiments. They can even be used to study how experimental probes disturb physical systems and in some cases they can be used to design molecules with desired physical properties.
The correctness of simulation protocol is crucial for obtaining physically correct and predictive results. If not chosen carefully, one can obtain quite spectacular but physically incorrect results. In the reference below [1], we demonstrate that there are critical several issues that need special attention especially in carbon nanotube systems. In particular, the treatment of charges is of extreme importance. In addition, thermostatting in Molecular Dynamics simulations may create additional problems. In addition to carbon nanotubes, our results also apply to biological systems such as aquaporin and other passive channels.
This movies shows water molecules entering a carbon nanotube. Hydrogen bonds are shown in yellow (notice how they form and break). See also the movie of a carbon nanotube connecting water reservoirs: nanotube model for aquaporin

The kit and its assembly:
This is a whif, but the Nanchang Q-6 was actually developed until 1989 – even though it never entered any service. It was over-ambitious and a dead end, overtaken by technological advances and the fact that Chinese development used to take decades rather than years.
Anyway, the Q-6 actually looked as if someone had glued the nose and air intake of a F-16 onto a MiG-23/27 fuselage - weird, but cool, so why not try this at home?
Like many kitbashing things, what sounds simple turned out to be a bit tricky in detail, even though the surgery was finally easier than expected. The model basis is pretty simple: I took an Academy MiG-27, sawed off the fuselage in the wing roots area (about 1cm, the cockpit section is an extra fuselage section), and did the same with an Italeri F-16 nose section, right behind the cockpit, where the front wheel well ends. The top insert for the single seater was left a bit longer, so that it would overlap with the MiG-23/27 spine.
When you fit these parts together, height is almost perfect, even the wing root/LERX angles match, but there are gaps left on the flanks where the original MiG-27 air intakes would be. These have to be covered, what creates lines reminiscent of the respective area on a MRCA Tornado. Furthermore, the spine behind the cockpit has to be sculpted, too.
Furthermore, the wing root levels of the MiG-23/27 and the F-16 did not match - they have a difference in height of about 4mm on the model, and this was the biggest challenge.
In order to compensate for this problem on my model, any LERX sign was removed from the F-16 nose. Inside of the F-16 section, a column was added that supports the rear upper half of the front fuselage, since the flanks had to go almost completely.
On the outside, the necessary intersections/extensions sculpted new with 2C putty, extending the MiG-23/27 lines forward. The final surface finish was done with NC putty. This major surgery was less complicated than expected - lots of work, though, but feasible.
The new front section with its blended fuselage/LERX area around the cockpit reminds surprisingly much of the MiG-29? As a side note: when you look at CG simulations of this aircraft, this area is a frequent field of trial and error. You find unconclusive, if not impossible designs.
Other changes include a less modern canopy from a MiG-21 (I think it comes from an Academy MiG-21F kit), which was more tricky to fit onto the original F-16 canopy than the LERX stuff. The F-16 canopy looked just too modern for my taste. An old Airfix pilot figure was added, too.
Another new feature is a new jet pipe, a J-79 nozzle from an Italeri Kfir that fits perfectly into the rear fuselage, and the fin. The latter was taken as a leftover part from my recent CF-151A project and comes from a 1:144 scale Tu-22M bomber (Dragon). It's higher, but less deep, and I thought that a slightly different shape and more area would be suitable for an attack aircraft. For the same reason the single, foldable stabilizer fin under the rear fuselage was replaced by two fixed strakes (from the F-16). Small details, but they change the look and make the aircraft appear more simple.
The landing gear was taken from the MiG-27, the front wheel strut had to be slightly shortened due to the reduced wheelbase on the Q-6.
The ordnance was puzzled together – according to current BAF weapons in use. I went for unguided missiles (taken from the Academy MiG-27 donation kit) and some 100kg iron bombs, leftover from a Trumpeter Il-28 bomber kit. These were arranged under the wing roots on improvised tandem MERs.
I did not even try to engrave new panel lines on the new front section - actually, almost the whole upper surface is featureless since it was made with putty. But bot 2C and NC putty are pretty touchy to drilling or engraving (as the rather fruitless attempt to drill open cavities for the two guns proved...), so I decided to just use paint effects.

Sensors are critical for both everyday technologies like smartphones and also for scientists studying tiny nanoparticle formations. Many sensors work by detecting extremely small vibrations, using a device called an oscillator. Argonne scientists are experimenting with new ways to make even tinier oscillators—many times smaller than the width of a human hair. As part of their work, they created this computer simulation showing how a miniscule gold core inside a silver shell changes with vibration.

Los Angeles Fire Department CERT (Community Emergency Response Team) Unit volunteers organized in Sylmar, CA to put their skills and abilities to the test. They conducted a simulation of a devastating earthquake that hits the San Fernando Valley, depleting first responding resources. CERT members from neighboring cities joined LAFD CERT members of our community to do "The Greatest Good for the Greatest Number of People." Search and Rescue K9s, LAFD UAVs, and over 120 CERT volunteers searched through the simulated disaster site of the Oakridge Mobile Home Community for residents in need of help. Utilizing their CERT training, these dedicated volunteers successfully organized CERT teams to conduct damage assessments, establish a medical treatment area, and extract trapped victims.

Dans le cadre de la Semaine nationale de la prévention de la noyade, les sauveteurs de la piscine la Joie ont pris part à une simulation d’un cas de colonne afin de faire de la prévention auprès de la population face aux dangers en piscine. Sous la supervision de la chef-sauveteur Laurie Gardner, l’équipe de sauveteur est intervenue afin d’effectuer un sauvetage simulé d’un baigneur ayant malencontreusement plongé dans la partie peu profonde de la piscine. Après avoir sifflé l’évacuation immédiate de la piscine, les sauveteurs ont travaillé de pair pour effectuer la sortie de l’eau de la victime blessée à la colonne vertébrale.
En cette Semaine nationale de prévention de la noyade, les ambulanciers d’Urgence Bois-Francs et les pompiers du Service de la sécurité publique de Victoriaville ont eux aussi participé à la simulation, et ont pris en charge la victime blessée à la colonne après la sortie de l’eau effectuée par les sauveteurs. Une communication efficace et le calme de tous ont contribué à faire de cet exercice de sauvetage un réel succès.
À la suite de cette simulation, des ateliers d’éducation au public ont été organisés avec la collaboration de Victoriaville en santé, et ce, tout au long de l’après-midi. Les personnes intéressées à connaitre quelques techniques de sauvetage et de réanimation cardiorespiratoire (RCR) ont pu se rendre sur place lors de cette journée de prévention.
La prochaine activité d’éducation au public portant sur les ateliers de sauvetage et de RCR est prévue le jeudi 31 juillet à 14 h à la piscine des Forges située sur la rue de l’Académie.

Ed and his team at Digital Domain built the synthetic Brad Pitt used in the film the “The Curious Case of Benjamin Button .“ You can see the real Brad Pitt on the left and the elderly simulated Brad Pitt on the right. Any need to hire real actors once you scan them??? Ed says yes, but I think the unions got to him =)
College of DuPage health Sciences students participated in a multi-discipline simulation involving students currently in the College's EMT, Nursing, CT, Surgical Tech, Nuclear Medicine and Respiratory Care programs. The scenario, played out by a combination of actors and mannequins involved a domestic situation in which a husband shot his wife and two children leaped from a two-story window to avoid a fire.

At Argonne National Laboratory, Type Ia supernovas, among the brightest exploding stars in the universe, are "cosmic yardsticks" whose application led to the discovery of dark energy. Astrophysicists are creating leadership computing simulations to better understand these explosions and by doing so help observers use them to determine the properties of dark matter.
