Neuropixels. Neuropixels probes (or "Neuropixels") are electrodes developed in 2017 to record the activity of hundreds of neurons in the brain. The probes are based on CMOS technology and have 1,000 recording sites arranged in two rows on a thin, 1-cm long shank.

The probes are used in hundreds of neuroscience laboratories including the International Brain Laboratory, to record brain activity mostly in mice and rats. By revealing the activity of vast numbers of neurons, Neuropixels probes are allowing new approaches to the study of brain processes such as sensory processing, decision making, internal state, and emotions and to create brain-machine interfaces.

The probes were announced in 2017. They are designed and fabricated by imec, an electronics research center in Belgium. In 2022, Neuropixels probes were inserted in human patients.

AMF Apollo 16. The AMF Apollo 16 is an American sailing dinghy that was designed by Canadian Bruce Kirby as a one-design racer and first built in 1977.

Production
The design was built by the Alcort division of American Machine and Foundry in the United States, starting in 1977. Alcort had been an independent company, but was bought out by AMF in 1969. A total of 1,100 Apollo 16s were built, but it is now out of production.

Design
The Apollo 16 is a recreational sailboat, built predominantly of fiberglass. It has a fractional sloop rig with aluminum spars. The hull features a raked stem, a vertical transom, a transom-hung, kick-up  rudder controlled by a tiller and a retractable, kick-up centerboard. It displaces .

The boat has a draft of  with the centerboard extended and  with it retracted, allowing beaching or ground transportation on a trailer. It has a hinged mast step to facilitate lowering the mast.

For sailing the design is equipped with internal halyards, an outhaul, boom vang and Cunningham. The mainsheet is controlled from the end of the boom and includes a full-beam mainsheet traveler. Both the mainsail and jib have built-in leech lines. Unusually the jib does not mount to the forestay, but is tensioned by its halyard. The boat is equipped with a stowage bin, hiking straps, plus dual Elystrom vacuum bailers. Factory options included a spinnaker, whisker pole and mainsail jiffy reefing.

The design has a Portsmouth Yardstick racing average handicap of 92.5 and is normally raced with a crew of two or three sailors.

Operational history
In a 1994 review Richard Sherwood wrote, "this one-design has an active racing class. It is designed to
carry two to four people comfortably in a large cockpit ... Modifications permitted for racing are minor, with the intention to keep Apollo a true one-design class."

Electric Loco Shed, Ajni. Electric Loco Shed, Ajni is a motive power depot performing locomotive maintenance and repair facility for electric locomotives of the Indian Railways, under its of the Central Railway division, located in , Nagpur in Maharashtra, India. It is one of the three electric locomotive sheds of the Central Railway, the others being at Kalyan (KYN) and Bhusawal. As of December 2024, there are 303 locomotives in the shed, including WAG-9 and WAP-7 locomotives.

History 
After Central Railway set a deadline to eliminate all steam locomotive operations by 1990, a push was given towards establishing electric locomotion as the primary motive power, and the steam locomotive sheds were decommissioned. To meet the needs of exponentially increasing rail traffic on the new continuous broad-gauge lines from Odisha to rest of India with the completion of gauge conversion, the Ajni was selected by Indian Railways for a new electric locomotive shed.

In the late 2003 WAM-4 were introduced which stayed until late 2000s, when they were transferred to Itarsi It later got a large fleet of WAG-7 locos from other sheds.

Operations 
Being one of the three electric engine sheds in Central Railway, various major and minor maintenance schedules of electric locomotives are carried out here. It has the sanctioned capacity of 200 engine units. Beyond the operating capacity, this shed houses a total of 284 engine units,all WAP-7 units. It also housed a few WAM-4 locomotives temporarily. Electric loco Shed, Ajni is now housing a large fleet of WAP-7 in Indian Railways and it caters to many long-distance electric trains.

Like all locomotive sheds, AJNI does regular maintenance, overhaul and repair including painting and washing of locomotives. It not only attends to locomotives housed at AJNI but to ones coming in from other sheds as well. It has four pit lines for loco repair. Locomotives of Ajni ELS along with Itarsi ELS were the regular links for all trains running through maharashtra when widespread electrification of railway lines started in East coast Railways. AJNI locomotives are also used for Rajdhani and Duranto trains as well.

Livery and markings 
Ajni WAP-7 has Haldiram's Sweets & Namkeens advertised on loco's body side.

Ajni locomotives have a standardized livery all over India.

Dazhushan Tunnel. The Dazhushan Tunnel (大柱山隧道) is a  railway tunnel in Baoshan, Yunnan, China as part of the Dali–Ruili railway. Construction of the tunnel began in August 2008 and was carried out by the First Engineering Bure Crec (中铁一局). Its construction was expected to take five years, but because of extreme geological conditions along its alignment, completion took place on 28 April 2020, after 12 years of construction. As another tunnel, Gaoligongshan Tunnel, along the railway line was still under construction, it did not enter service until 2022.

The justification of this tunnel is the geopolitical importance of the Dali–Ruili railway. While there were already gas and oil pipelines linking the oil refinery in Yunnan to the port of Bay of Bengal in Myanmar, a direct railway link between China and Myanmar was seen as a doubly secure means for China to access the Bay of Bengal in case the territorial disputes in the South China Sea are resolved unfavorably to China.

Toyota Ha:mo. The Toyota Ha:mo (from Harmonious Mobility) is a system for organizing public transport, integrating short-term rental of public electric vehicles with public transport. The second pillar of the system is the portal available in the browser and as a mobile application, suggesting the best combinations of connections and means of transport, taking into account public transport and automatic vehicle pickup points located in various points of the city. The portal and mobile application allow you to reserve a vehicle at a selected point.

The most used vehicle in the Ha:mo short-term rental system is the Toyota i-Road, a small three-wheeled vehicle that combines the features of a car and a scooter. The Ha:mo systems also use the COMS electric microcar produced by Toyota Auto Body.

So far (October 2015), Ha:mo has been implemented as a pilot program in three cities - Toyota, Grenoble and Tokyo.

Toyota declares that "The aim of the Ha:mo project is to try to organize low-emission, individual urban transport, i.e. producing minimal amounts of exhaust gas, without limiting the mobility of the society. The program is to lead to an effective increase in mobility thanks to new technological achievements. As part of Ha:mo, Toyota is constantly develops research on supercompact electric vehicles for short distances around the city."

Reticulation (metalwork). In metalwork, reticulation refers to a decorative surface finishing technique involving the application of localised heat to the surface of a metal object. Reticulation is typically performed on alloys of silver and copper or of gold and copper.

Reticulation exploits the difference between the melting temperature of an unalloyed metal and that of an alloy of the metal; by depleting the base metal content in the surface layer, a piece can be heated in such a manner so as to render the interior of the piece molten while leaving the surface of the piece intact. The reticulated surface is formed by the thermal expansion and contraction of the interior metal which is effected by deliberate variation in the application of localised heat.

In the late 19th century, reticulation was used as a decorative technique by Russian goldsmiths such as Fabergé, where the process was referred to as samorodok (lit. "born by itself"). Use of the technique spread to the Nordic and Scandinavian countries where it was applied in the creation of objects such as cigarette boxes, card cases, eyeglass cases, and flasks.

AC 00-69. The Advisory Circular AC 00-69, Best Practices for Airborne Software Development Assurance Using EUROCAE ED-12( ) and RTCA DO-178( ), initially issued in 2017, supports application of the active revisions of ED-12C/DO-178C and AC 20-115. The AC does not state FAA guidance, but rather provides information in the form of "best practices" complementary to the objectives of ED-12C/DO-178C.

 Notably, the guidance of FAA Order 8110.49 regarding "Software Change Impact Analysis" was removed in Revision A of that notice in 2017. The best practices that AC 00-69 now describes for Software Change Impact Analysis are much reduced and less prescriptive than what was removed from Order 8110.49.
 This AC clarifies that Data Coupling Analysis and Control Coupling Analysis are distinct activities and that both are required for satisfying objective A-7 (8) of ED-12C/DO-178C and ED-12B/DO-178B, adding that data and control coupling analyses rely upon detailed design specification of interfaces and dependencies between components.
 The AC also recommends that error handling (how the software avoids, detects, and handles runtime error) should be defined in explicit, reviewed design specifications rather than implemented ad hoc in the source code.
