Shuiyousphaeridium is an extinct genus of acritarch discovered in 1993. [1] Dated to 1.8Ga, it represents one of the earliest fossil eukaryote taxa.

Acritarch microfossils

Acritarchs are organic microfossils, known from approximately 1.8 billion years ago to the present. Their diversity reflects major ecological events such as the appearance of predation and the Cambrian explosion.

Eukaryote taxonomic group whose members have complex structures enclosed within membranes

Eukaryotes are organisms whose cells have a nucleus enclosed within membranes, unlike prokaryotes, which have no membrane-bound organelles. Eukaryotes belong to the domain Eukaryota or Eukarya. Their name comes from the Greek εὖ and κάρυον. Eukaryotic cells also contain other membrane-bound organelles such as mitochondria and the Golgi apparatus, and in addition, some cells of plants and algae contain chloroplasts. Unlike unicellular archaea and bacteria, eukaryotes may also be multicellular and include organisms consisting of many cell types forming different kinds of tissue. Animals and plants are the most familiar eukaryotes.

An integer is a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 5 1/2, and 2 are not.

Redshift increase in wavelength (decrease in frequency) of an electromagnetic radiation

In physics, redshift is a phenomenon where electromagnetic radiation from an object undergoes an increase in wavelength. Whether or not the radiation is visible, "redshift" means an increase in wavelength, equivalent to a decrease in wave frequency and photon energy, in accordance with, respectively, the wave and quantum theories of light.

Square root inverse operation of square for finding the original base number

In mathematics, a square root of a number a is a number y such that y2 = a; in other words, a number y whose square (the result of multiplying the number by itself, or yy) is a. For example, 4 and −4 are square roots of 16 because 42 = (−4)2 = 16. Every nonnegative real number a has a unique nonnegative square root, called the principal square root, which is denoted by a, where √ is called the radical sign or radix. For example, the principal square root of 9 is 3, which is denoted by 9 = 3, because 32 = 3 · 3 = 9 and 3 is nonnegative. The term (or number) whose square root is being considered is known as the radicand. The radicand is the number or expression underneath the radical sign, in this example 9.

National Parks of Poland

There are 23 national parks in Poland. These were formerly run by the Polish Board of National Parks, but in 2004 responsibility for them was transferred to the Ministry of the Environment. Most national parks are divided into strictly and partially protected zones. Additionally, they are usually surrounded by a protective buffer zone called otulina.

ANSEL, the American National Standard for Extended Latin Alphabet Coded Character Set for Bibliographic Use, was a character set used in text encoding. It provided a table of coded values for the representation of characters of the extended Latin alphabet in machine-readable form for thirty-five languages written in the Latin alphabet and for fifty-one romanized languages. The standard was reaffirmed in 2003 although it has been administratively withdrawn by ANSI effective 14 February 2013. It is registered as Registration # 231 in the ISO International Register of Coded Character Sets to be Used with Escape Sequences.

Kriging method of interpolation

In statistics, originally in geostatistics, kriging or Gaussian process regression is a method of interpolation for which the interpolated values are modeled by a Gaussian process governed by prior covariances. Under suitable assumptions on the priors, kriging gives the best linear unbiased prediction of the intermediate values. Interpolating methods based on other criteria such as smoothness need not yield the most likely intermediate values. The method is widely used in the domain of spatial analysis and computer experiments. The technique is also known as Wiener–Kolmogorov prediction, after Norbert Wiener and Andrey Kolmogorov.

In statistical inference, specifically predictive inference, a prediction interval is an estimate of an interval in which a future observation will fall, with a certain probability, given what has already been observed. Prediction intervals are often used in regression analysis.

Generation Z, also known by a number of other names, is the demographic cohort after the Millennials. Demographers and researchers typically use the mid-1990s to mid-2000s as starting birth years. There is little consensus regarding ending birth years. Most of Generation Z have used the Internet since a young age and are comfortable with technology and social media.

Semiparametric regression

In statistics, semiparametric regression includes regression models that combine parametric and nonparametric models. They are often used in situations where the fully nonparametric model may not perform well or when the researcher wants to use a parametric model but the functional form with respect to a subset of the regressors or the density of the errors is not known. Semiparametric regression models are a particular type of semiparametric modelling and, since semiparametric models contain a parametric component, they rely on parametric assumptions and may be misspecified and inconsistent, just like a fully parametric model.

Chevrolet Camaro (fourth generation) Fourth generation of the muscle/pony car manufactured by American automobile manufacturer Chevrolet from 1992–2002

The fourth generation of the Camaro was produced by American automobile manufacturer Chevrolet for the 1993 through 2002 model years; although the last 30 models were unofficially sold in 2003. It was introduced on an updated F-body platform, but would retain the same characteristic since the first-generation's introduction back in 1967; 2-doors, 2+2 seating, coupe or convertible bodystyles, rear-wheel drive, and a choice of pushrod V6 and V8 powerplants. The Camaro was refreshed and revised in 1998 with both exterior and engine changes. The fourth-generation of the Camaro would continue production up to the 2002 model year when General Motors discontinued production due to slow sales, a deteriorated sports coupé market, and plant overcapacity.
