Muzzle reference system. A muzzle reference system (MRS) is a device used on most modern tank guns and some artillery systems that measures the bending of the barrel due to heat, gravity and other issues. It normally consists of a laser device and detector mounted at the breach end of the gun, often co-located with other optics like the gunner's sight, and a mirror at the muzzle. By measuring the deflection of the barrel, corrections can be applied by the ballistic computer to correct for changes as the gun is fired.

Pyranthrene (molecule). Pyranthrene is a molecule with the chemical formula .

Properties 
Pyranthrene is made up of eight benzene rings fused together, which classes it as a polycyclic aromatic hydrocarbon.

It has a reddish-brown color, but turns to a yellowish color when it is purified via sublimation. The difference between these two forms of the molecule comes from the difference in the degrees of their crystallinity. The brown form of pyranthrene forms more perfect crystallites than the yellow form does.

Pyranthrene is also an organic semiconductor. It displays photoconductive properties when it is in a solid state, as well as when it is dissolved in a benzene solution.

It has a density of 1.4±0.1 g/cm3.

Uses 
Pyranthrene has potential uses as a material used to make organic light-emitting diodes and solar cells.

In addition, it has photophysical properties that allow it to be useful for biological imaging and sensing. However, pyranthrene has been shown to cause oxidative stress and DNA damage within cells, and is classed as a carcinogen and an endocrine disruptor, which heavily limits its use in biological systems.

Synthesis 
Pyranthrene can be synthesized by reducing pyranthrone with zinc dust, acetic acid, and pyridine.

Combatant Craft Medium. The Combatant Craft Medium, Mark1 (CCM) is a United States Navy patrol boat designed for use by the United States Naval Special Warfare Command as a multi-mission surface tactical mobility craft built by Vigor Industrial "to provide small-caliber gunfire support, infiltrate and exfiltrate Special Operation Forces, conduct VBSS (Visit, board, search, and seizure), special reconnaissance, coastal patrol and interdiction, counter terrorism operations, and FID (Foreign Internal Defense)," per the U.S. Navy.

Development

Initially conceived as a replacement of the now retired Mark V Special Operations Craft until that RFP was canceled in April 2010. The revised proposal specified a C-17 transportable replacement for the discontinued Naval Special Warfare RHIBs, which were originally transportable on the smaller C-130 aircraft.

Designed by Michael Peters Yacht Design, the CCM evolved from Oregon Iron Works' Alligator and Sealion concepts, initially in cooperation with Israel Defense Forces. Oregon Iron Works and United States Marine, Inc were awarded initial contracts to develop their existing concepts into the CCM in September 2011, with Oregon Iron Works winning the selection process to produce a total of 35 CCMs over 7 years by United States Special Operations Command in February 2014.

In May 2014, Oregon Iron Works announced its merger with fellow Oregon shipbuilder Vigor Industrial in order to facilitate the $400 million contract, as well as subcontracting marine electronics systems to Leidos.

The first CCMs were delivered and commissioned in 2015, featuring a low observable profile, with longer range, operable in higher sea states, and with increased protection and shock mitigation for its crew and passengers than the NSW RHIBs it replaces. Its electronics package includes a remote weapon station and sensors, Blue Force Tracker, a DAGR jam-resistant GPS receiver, and advanced tactical radios. Each hull is individually numbered, though not named; the vessels are operated by SWCC Boat Teams.

In May 2023, it was announced that Norway's Naval Special Operations Command gained approval from the Pentagon to acquire 2 CCMs to be delivered in 2025.

Triiron ditin intermetallic. The compound with empirical formula Fe3Sn2 is the first known kagome magnet.  It is an intermetallic compound composed of iron (Fe) and tin (Sn), with alternating planes of Fe3Sn and Sn.

Preparation
The iron-tin intermetallic forms at around  and naturally assumes a kagome structure.  Quenching in an ice bath then cools the material to room temperature without disrupting the atomic structure.

Electronic structure 
The compound's band structure exhibits a double Dirac cone, enabling Dirac fermions.  A 30 meV gap separates the cones, which indicates the quantum Hall effect and massive Dirac fermions.  Close measurement of the Fermi surface via the de Haas-van Alphen effect suggests that the massive fermions also exhibit Kane-Mele-type spin-orbit coupling.

Fe3Sn2 can also host magnetic skyrmions, but these typically require high magnetic fields to nucleate.  For samples with a small (but nonzero) thickness gradient, only a small-amplitude (5-10 mT), direction-variant magnetic field suffices to nucleate the quasiparticles.

Takashi Akasaka. Takashi Akasaka (1925-2010) was a Japanese engineering professor at Chuo University known for his work on cord-rubber composites and tires.

Education 

Akasaka completed his undergraduate studies during world war II, graduating from the Applied Mathematics Section of the Engineering Department of the University of Tokyo in 1946. He was first in his class in the Astronautics Department but because research in Aeronautical Engineering was prohibited in Japan after the war, the Astronautics Department was
reorganized as the Applied Mathematics Department. Not finding employment, Akasaka continued at the University of Tokyo as an assistant to Tsuyoshi Hayashi, who was working on tires. Akasaka received a doctorate degree in 1962 from the University of Tokyo at the age of 37. His dissertation developed a theory of cord-rubber composites based on an assumption of inextensible cords.

Career 

Akasaka joined the faculty of Chuo University in 1952 as a lecturer, teaching mathematics.  In 1962 he joined the engineering department, teaching mechanics of materials.  Along with Joseph Padovan, he was a founding associate editor and the longest serving associate editor of the journal Tire Science and Technology with 36 years.  He delivered the 1989 invited plenary address at the Tire Society conference.  He retired from the university in 1995 and remained an honorary faculty member.  

His most cited work derived analytical equations describing the contact pressure distribution of a radial tire rolling with a camber angle.

Awards

 2011 - Tire Society Distinguished Achievement Award The award was made posthumously, and Akasaka's son Shuichi Akasaka accepted the award at the meeting.
