VX-1. VX-1, Air Test and Evaluation Squadron One, (AIRTEVRON ONE) is a United States Navy air test and evaluation squadron based at Naval Air Station Patuxent River, Maryland.

Operations
Operational aircraft are assigned to VX-1 including the P-8A Poseidon, E-2D Advanced Hawkeye, MH-60R and MH-60S. Additionally, VX-1 provides test and evaluation support for aircraft such as the KC-130J Hercules, E-6B Mercury, MQ-8B Fire Scout, and MQ-4C Triton Unmanned Aerial Vehicles.

The squadron operated two specially equipped P-3 aircraft that were equipped to collect data from the large sonobuoy fields used by the Sonobuoy Missile Impact Location System (SMILS) which supported the Navy's fleet ballistic missile program testing. The aircraft modifications enabled the aircraft to receive and record more sonobuoys, had a special timing system and a data monitoring and quick look capability. The Air Force Advanced Range Instrumentation Aircraft could also operate with SMILS.

Mission statement
The principal mission of VX-1 is to test and evaluate airborne anti-submarine warfare (ASW) and maritime anti-surface warfare (SUW) weapon systems, airborne strategic weapon systems, as well as support systems, equipment and materials in an operational environment. The squadron also develops, reviews and disseminates new ASW/SUW tactics and procedures for fleet use.

History

VX-1 formed during WWII in response to the German submarines threat.  The response by the United States was the commissioning of the Air Antisubmarine Commander Air Force, Atlantic Fleet, on 1 April 1943 at Quonset Point, Rhode Island.

The squadron left NAS Key West, Florida on or about 1 July 1973 when the squadron moved to its current home at NAS Patuxent River, Maryland.

Commanding officer
Current Commanding Officer of VX-1 is Captain John Riley, an E-2D Naval Flight Officer and Carrier Airborne Early Warning Weapons School (CAEWWS) graduate.

Chōsen Railway Class 810. The Class 810 was a class of steam tender locomotives for freight trains with 2-8-0 wheel arrangement operated by the Chōsen Railway in colonial Korea.

Description
The first four were built for the Chōsen Railway in 1935 by Kisha Seizō of Japan for use on the railway's Hambuk Line, intended to haul iron ore trains; they were numbered 810 through 813. Work to convert this line was converted to standard gauge was completed on 1 May 1940, after which the locomotives were transferred to the railway's Hwanghae Line, Suin Line, and Suryeo Line.

A second batch of four, numbers 814 through 817 were delivered by Kisha Seizō in 1936.

Postwar
After the Liberation and partition of Korea, these locomotives were divided between the Korean State Railway of North Korea and the Korean National Railroad of South Korea. Those which ended up in the North were numbered in the 500 series, with three still surviving - one operational - in 2004.

1,3-Bis(aminomethyl)cyclohexane. 1,3-bis(aminomethyl)cyclohexane (1,3-BAC) are a collection of organic compounds with the formula .  The compounds belong to the sub class cycloaliphatic amine. Their key use is as an epoxy resin curing agent.

Manufacture 
It has been produced commercially as part of a mixture with the 1,4 derivative. The primary route of manufacture is by catalytic hydrogenation of m-xylylenediamine usually called MXDA.

Uses 
Like most amines it maybe used as an epoxy curing agent. However, the presence of the amino group also means it can be used in polyurethane chemistry by reacting with isocyanates. In this case a polyurea would be produced. It may also be reacted with phosgene (phosgenation) to produce an isocyanate.

Safety 
It is corrosive with a Packing Group I designation.

Auspace. Auspace Pty Ltd was an Australian aerospace company formed on 7 June 1982 as a joint-venture between Hawker de Havilland Australia and SA Matra Espace. It was primarily known for its work as a major contractor for the Keating National Space Program that took place between 1986 and 1996.

In 2007 Auspace was acquired by the Nova Group, and was absorbed completely into the two10degrees Ltd. subsidiary in 2019.

History 

Even before the National Space Program, Auspace was a large player in the Australian space industry, managing parts of the multi-million dollar UV-optical space telescope Starlab project. The working relationship formed with the Department of Industry, Technology and Commerce under the project would be beneficial when the National Space Program commenced a few years later in 1986.

Under the National Space Program, Auspace received 28% of all funds distributed, the most of any company besides British Aerospace Australia. Under the program, Auspace developed instruments for CSIRO, Hispasat, Locstar, and multiple other major projects.

In December 1988 Auspace was sold to Plessey Australia. After the bankruptcy of Plessy later that year, Auspace was bought by Matra Marconi Space.

In 1992 the Auspace built Endeavour satellite made its inaugural launch, but failed to fulfill the mission requirements. In 1995 the satellite was successfully relaunched.

In 2007 Auspace was purchased by the Nova Group.

In 2019 it was merged with two10degrees.

Oškinis BRO-16. The Oškinis BRO-16, sometimes known as the Oškinis BRO-16 Pempė (Pempė in Lithuanian translates as Northern Lapwing), was a flying boat, biplane training glider, flown and produced in the USSR in the 1970s.

Design and development

The BRO-16 was a single-seat training glider, unusual for being both a biplane and a flying boat. It was a development of the BRO-11 land monoplane produced some twenty years earlier and first flew in August 1973.

Its wings were rectangular in plan out to rounded tips. The lower wing was 25% shorter in span than the upper but with about the same chord and ply-covered in contrast to the fabric covered upper wing. Both wings had single-spar structures and were braced together with wide spread, transverse, streamlined and distorted V-struts between the spars. There was no stagger, 3° of dihedral and a large interplane gap. The BRO-16's push-rod activated, fabric-covered ailerons, which could also serve as flaps, were suspended from the upper wing and filled 87% of the span.

The BRO-19's fuselage had a forward nacelle attached to a flat girder fuselage supporting the tail. The largely wooden nacelle was  long and flat-bottomed. The cockpit, close to the nose, was open and placed the pilot over the leading edge of the lower wing which was mounted on the side of the nacelle, about halfway back. The rear of the fuselage was formed by a horizontal girder member, just under the upper wing, attached to the nacelle with a pair of vertical struts between the wings and an oblique strut from the rear of the nacelle to the top of the aft vertical strut. Wires braced the rear fuselage to the wing struts and to the nacelle. Parts of the girder were canvas-covered.

The tail was conventional. Though the triangular fin was very small, the rudder was large, nearly rectangular in profile apart from a blunted top and a slightly angled underside. The tailplane was triangular in plan and carried rectangular elevators. All the tail surfaces were fabric-covered wooden structures.

Operational history

The BRO-16 was mass produced, though numbers are not available. They operated from the Lithuanian Kaunas Reservoir.

Variants
BRO-16 Pempėmain production variant.
BRO-17U Utochka Short span ( variant. Rectangular plan wings, the upper divided into three staggered, overhanging slats. Completion uncertain.

Watergen. Watergen Inc. (formerly Water-Gen) is an Israel-based global company that develops atmospheric water generator (AWG) systems. Its systems generate water from air at 250 Wh per liter.

History
Watergen was founded in 2009 by entrepreneur and former military commander Arye Kohavi and a team of engineers with the goal of providing freely accessible water to troops around the world.

Following the acquisition of Watergen by billionaire Michael Mirilashvili, in 2016, the company turned its attention to addressing water scarcity and responding to the needs of people in the aftermath of natural catastrophes.

Since then, Watergen has created a series of products that are appropriate for a variety of applications, ranging from remote rural locations to commercial office complexes. and private homes. It has been used around the world by armies as well as the public and private sectors in the United States, Latin America, India, Vietnam, Uzbekistan and the African continent.

The company's headquarters are in Petah Tikva. It has a subsidiary in the United States.

In May 2020, the company installed a water-from-air device at the Al-Rantisi Hospital in Gaza. This initiative, a result of a collaboration with the Palestinian power company Mayet Al Ahel, aimed to provide clean and safe off-grid drinking water for the pediatric hospital's staff and patients. The project, led by Mirilashvili, intended to address water scarcity in the Gaza Strip.

Herbert Wurlitzer. The company Herbert Wurlitzer Manufaktur für Holzblasinstrumente GmbH is a German clarinet manufacturer based in Neustadt an der Aisch, Bavaria with a second production site in Markneukirchen, Saxony. It was founded in 1959 by Herbert Wurlitzer. His father Fritz Wurlitzer operated since the 1930s in Erlbach, now a district of Markneukirchen, a manufactory for the production of clarinets. The company W. Wurlitzer makes clarinets with German System (Oehler fingering system) and with the "Reform Boehm system", developed by Fritz Wurlitzer in the late 1940s, an instrument with Boehm fingering system and the sound of an Oehler Clarinet.

Biography 

Herbert Wurlitzer escaped from East Germany in 1959 with his family into the Federal Republic of Germany. Here he built a manufactory for the production of clarinets, as he had learned from his father in Erlbach, Vogtland.

He managed the company until his death in 1989 together with his wife Ruth Wurlitzer. Ruth Wurlitzer continued the business together with Bernd Wurlitzer, her son-in-law as commercial director and her son Frank-Ulrich as artistic director. Since the death of Ruth in September 2014 the company is run only by Frank-Ulrich and Bernd Wurlitzer.

The enterprise 

The extensive family Wurlitzer (there is also an American branch) has been manufacturing musical instruments for several generations.

The company Herbert Wurlitzer was initially located in Bubenreuth / Bavaria and moved its headquarters in 1964 to Neustadt an der Aisch. In 1992, the company built another production site in Markneukirchen, where numerous musical instrument makers are based. In this context, it also took over the former workshop of Fritz Wurlitzer, which was integrated into the new production after some time.

The company produces almost all clarinets of the clarinet family (with the exception of the very rare double bass clarinet and the contralto clarinet). All instruments are made only of wood, mainly grenadilla wood, but also cocobolo and boxwood are available. They are made exclusively to order individually.
Herbert Wurlitzer acquired with his company a significant position nationally and internationally.The main exporting countries are the Netherlands, Italy, Spain and Japan. There was and still is a low distribution in the USA.

Wurlitzer clarinets are represented in Germany and some other countries in numerous cultural orchestras.

Brain storm optimization algorithm. The brain storm optimization algorithm is a heuristic algorithm that focuses on solving multi-modal problems, such as radio antennas design worked on by Yahya Rahmat-Samii, inspired by the brainstorming process, proposed by Dr. Yuhui Shi.

More than 200 papers related to BSO algorithms have appeared in various journals and conferences. There have also been special issues and special sessions on Brain Storm Optimization algorithm in journals and various conferences, such as Memetic Computing Journal.

There are a number of variants of the algorithms as well, such as Hypo Variance Brain Storm Optimization, where the object function evaluation is based on the hypo or sub variance rather than Gaussian variance, and Global-best Brain Storm Optimization, where the global-best incorporates a re-initialization scheme that is triggered by the current state of the population, combined with per-variable updates and fitness-based grouping.

Carleton University researchers proposed another variant by using a periodic quantum learning strategy to provides new momentum, enabling individuals to escape local optima (local optimum).

A number of comparison studies are conducted between PSO and BSO. Recently published book contains much more up to date references. It was used to design 5G network as well.

Christopher Jarzynski. Christopher Jarzynski is an American physicist and distinguished university professor at University of Maryland's department of chemistry and biochemistry, department of physics, and institute for physical science and technology, and fellow of the National Academy of Sciences. He is known for his contributions to non-equilibrium thermodynamics and statistical mechanics, for which he was awarded the 2019 Lars Onsager Prize. In 1997, he derived the now famous Jarzynski equality, confirmation of which was cited by the Nobel Committee for Physics as an application of one of the winning inventions of the 2018 Nobel Prize in physics—optical tweezers.

Education and research
Jarzynski graduated from Our Lady of Good Counsel High School in Wheaton, Maryland in 1983.  He then attended Princeton University from where he graduated with high honors with an A.B. in physics in 1987 after completing a senior thesis titled "An experimental search for 1.7 MEV axions in nuclear decays, 'the detector from hell'."  He received his Ph.D. in physics in 1994 from University of California, Berkeley, under the supervision of Władysław J. Świątecki and Robert Grayson Littlejohn.

At University of California, Berkeley, Jarzynski studied adiabatic invariants in chaotic classical systems. After graduating with a PhD, he spent ten years at Los Alamos National Laboratory, and since 2006 he has been faculty at the University of Maryland, College Park. His research is primarily in the area of non-equilibrium statistical mechanics, where he has contributed to an understanding of how the laws of thermodynamics apply to nanoscale systems. In 1997, he derived an equality, now known as the Jarzynski equality, that relates nonequilibrium fluctuations to equilibrium free energy differences, a result that has been verified in numerous experiments and has found applications in biophysics and computational chemistry. His current interests also include the thermodynamics of information processing, as well as shortcuts to adiabaticity in quantum, classical and stochastic systems.

Awards and honours 
He has been the recipient of a Fulbright Fellowship, the Sackler Prize in the Physical Sciences, and the 2019 Lars Onsager Prize. He is a fellow of the American Physical Society and the American Academy of Arts and Sciences. In 2020 he was elected to the National Academy of Sciences and awarded a Guggenheim Fellowship and Simons Fellowship.

Jarzynski is a member of the editorial board of the Journal of Statistical Mechanics: Theory and Experiment, and an associate editor of the Journal of Statistical Physics.
