BA.2.86 is an Omicron subvariant of SARS-CoV-2, the virus that causes COVID-19. BA.2.86 is notable for having more than thirty mutations on its spike protein relative to BA.2. [1] The subvariant, which was first detected in a sample from 24 July 2023, [2] is of concern due to it having made an evolutionary jump on par with the evolutionary jump ...
It was first marketed in 1988. The Rubik's Clock is a two-sided puzzle, each side presenting nine clocks to the puzzler. There are four dials, one at each corner of the puzzle, each allowing the corresponding corner clock to be rotated directly. (The corner clocks, unlike the other clocks, rotate on both sides of the puzzle simultaneously and ...
1/52! chance of a specific shuffle Mathematics: The chances of shuffling a standard 52-card deck in any specific order is around 1.24 × 10 −68 (or exactly 1 ⁄ 52!) [4] Computing: The number 1.4 × 10 −45 is approximately equal to the smallest positive non-zero value that can be represented by a single-precision IEEE floating-point value.
BA.2.86 features more than 30 mutations compared to omicron XBB.1.5, which was the dominant variant for most of 2023 — it's also the strain targeted in the updated COVID-19 vaccine. Last month ...
Matrices have a long history of application in solving linear equations but they were known as arrays until the 1800s. The Chinese text The Nine Chapters on the Mathematical Art written in the 10th–2nd century BCE is the first example of the use of array methods to solve simultaneous equations, [103] including the concept of determinants.
A novel method of determining the supergiant's mass was proposed in 2011, arguing for a current stellar mass of 11.6 M ☉ with an upper limit of 16.6 and lower of 7.7 M ☉, based on observations of the star's intensity profile from narrow H-band interferometry and using a photospheric measurement of roughly 4.3 AU or 955 ± 217 R ☉.

Pyongyang [a] (Korean: 평양; Hancha: 平壤) is the capital and largest city of the Democratic People's Republic of Korea (DPRK), commonly known as North Korea, where it is sometimes labeled as the "Capital of the Revolution" (혁명의 수도). [8]
China's population growth rate is −0.15%, ranking 159th in the world. [ citation needed ] China conducted its sixth national population census in 2010, [ 9 ] [ 10 ] and its seventh census was completed in late 2020, with data released in May 2021.
