Vigil (Spacecraft)
Vigil, formerly known as Lagrange, is a planned solar weather mission by the European Space Agency (ESA). It envisions two spacecraft to be positioned at Lagrangian points L1 and L5. Monitoring space weather includes events such as solar flares, coronal mass ejections, geomagnetic storms, solar proton events, etc. Monitoring would help predict arrival times at the Earth and any potential effect on infrastructure. The Vigil spacecraft are anticipated to launch in the mid 2020s. On 17 May 2021, ESA began soliciting design concept studies from various European industrial and scientific consortiums for the mission. A final design will be selected after approximately 18 months, in late 2022. Simultaneously, the ESA announced the No-Name Mission contest to replace the placeholder Lagrange name. The winning name, Vigil, was announced on 10 February 2022.

Viewing Angle Switchable Liquid Crystal Devices
For pure liquid crystals (LCs) system, methods for switchable viewing angle devices are divided into hybrid aligned nematic (HAN) LC cells, double cells, pixel division and three-electrode structure. Utilizing 3M light-control film and PDLC film together to create switchable anti-peeping film, PDLC is a voltage-controlled LC film that can switch between transparent and scattering, light scattering intensity of PDLC film is dependent on electric field, switchable voltage between light scattering (share mode) and transparent state (privacy mode) is approximately 5.0 V.

Vietnamese Migrant Brides in Taiwan
Vietnamese migrant brides in Taiwan represent marriages between Taiwanese men and Vietnamese brides who are mostly from poor, rural areas of Vietnam, such as those along the Mekong Delta. As of 2006, out of Taiwan’s immigrant population of approximately 428,240 people (up from 30,288 in 1991), 18% were females who had relocated to the country through marriage. Out of this population, about 85% originated from the Southeast Asian countries of Vietnam, Indonesia, Thailand, and Philippines , with the majority hailing from Vietnam. It is estimated that between the years of 1995 and 2003, the number of Vietnamese women married to Taiwanese men increased from 1,476 to more than 60,000 individuals, making the Vietnamese the largest non-Chinese immigrant group living in the island.

Vienna Philharmonic (Coin)
The Vienna Philharmonic (German: Wiener Philharmoniker), often shortened to Philharmonic, is a bullion coin of gold, silver, or platinum produced by the Austrian Mint (Münze Österreich). The coin is named for the Vienna Philharmonic orchestra, which inspired the design of both sides. It was introduced in 1989 as a one-troy ounce (ozt), gold coin with a face value of 2,000 Austrian schillings. It is generally one of the world's best selling bullion coins. In 2002, with the adoption of the euro currency, the nominal value of the one-ounce coin was changed to 100 euros. In 2008, the Mint introduced a one-ounce silver version of the coin with a nominal value of 1.50 euros. The silver coin is also one of the top selling bullion coins, ranked third in 2013. In 2016, the mint introduced a one ounce platinum coin with a face value of 100 euros. Like any bullion coin, the value is based primarily on the metal content and the spot price of that metal on the commodities markets. The gold Philharmonic has a fineness of 999.9 (often written 0.9999, also known as 24 carat or 99.99% pure). In most countries in Europe, the gold Philharmonic is traded VAT-free while the Silver Philharmonic is partly subject to a reduced VAT rate. The coins are minted according to demand and production varies from year to year accordingly. The design on the coin remains the same each year; only the year of issue changes. From the outset, the obverse of the coin depicts the pipe organ in the Vienna Musikverein's Golden Hall. The reverse of the coin shows instruments of the Vienna Philharmonic, including Vienna horn, bassoon, harp, and four violins centered on a cello. Both designs were produced by the chief engraver of the Austrian Mint, Thomas Pesendorfer.
