Baud

In telecommunication and electronics, baud (/ˈbɔːd/, unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second or pulses per second. It is the number of distinct symbol changes (signaling events) made to the transmission medium per second in a digitally modulated signal or a line code.

Digital data modem manufacturers commonly define the baud as the modulation rate of data transmission and express it as bits per second.

Baud is related to gross bit rate expressed as bits per second.

Definitions

The symbol duration time, also known as unit interval, can be directly measured as the time between transitions by looking into an eye diagram of an oscilloscope. The symbol duration time T_s can be calculated as:

where f_s is the symbol rate. There is also a chance of miscommunication which leads to ambiguity.

In digital systems (i.e., using discrete/discontinuous values) with binary code, 1 Bd = 1 bit/s. By contrast, non-digital (or analog) systems use a continuous range of values to represent information and in these systems the exact informational size of 1 Bd varies.

Methyl-CpG-binding domain protein 2

Methyl-CpG-binding domain protein 2 is a protein that in humans is encoded by the MBD2 gene.

Function

DNA methylation is the major modification of eukaryotic genomes and plays an essential role in mammalian development. Human proteins MECP2, MBD1, MBD2, MBD3, and MBD4 comprise a family of nuclear proteins related by the presence in each of a methyl-CpG-binding domain (MBD). Each of these proteins, with the exception of MBD3, is capable of binding specifically to methylated DNA. MECP2, MBD1, and MBD2 can also repress transcription from methylated gene promoters. The protein encoded by this gene may function as a mediator of the biological consequences of the methylation signal. It is also reported that this protein functions as a demethylase to activate transcription, as DNA methylation causes gene silencing if present in promoter regions.

Interactions

Methyl-CpG-binding domain protein 2 has been shown to interact with:

Ice

Ice is water frozen into a solid state. Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color.

In the Solar System, ice is abundant and occurs naturally from as close to the Sun as Mercury to as far as the Oort cloud. Beyond the Solar System, it occurs as interstellar ice. It is abundant on Earth's surface – particularly in the polar regions and above the snow line – and, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate. It falls as snowflakes and hail or occurs as frost, icicles or ice spikes.

Ice molecules can exhibit up to sixteen different phases (packing geometries) that depend on temperature and pressure. When water is cooled rapidly (quenching), up to three different types of amorphous ice can form depending on the history of its pressure and temperature. When cooled slowly correlated proton tunneling occurs below 20 K giving rise to macroscopic quantum phenomena. Virtually all the ice on Earth's surface and in its atmosphere is of a hexagonal crystalline structure denoted as ice Ih (spoken as "ice one h") with minute traces of cubic ice denoted as ice Ic. The most common phase transition to ice Ih occurs when liquid water is cooled below 0°C (273.15K, 32°F) at standard atmospheric pressure. It may also be deposited directly by water vapor, as happens in the formation of frost. The transition from ice to water is melting and from ice directly to water vapor is sublimation.

Ice (1998 film)

Ice is a 1998 television disaster film starring Grant Show, Udo Kier, and Eva La Rue. The film has a similar premise as The Day After Tomorrow, a science fiction disaster film released six years later. Though completely in English, it first premiered in Germany in 1998 before being aired on ABC in the United States in 2000.

Plot

A small meteor hits the sun, causing disastrous consequences for the Earth. Los Angeles is, just as the rest of the world, covered with a layer of ice and snow. The government has collapsed and everyone is on their own. Chaos and crime prevails. Together with scientist Dr. Kistler and a small group of survivors, L.A. cop Robert Drake leaves in the direction of Long Beach Harbor to meet with a government ship which will take them to Guam, where it is warmer.

Cast

Ice (band)

Ice is an industrial music band formed by guitarist Justin Broadrick and saxophonist/vocalist Kevin Martin.

History

Keeping to a similar vein as their other musical project Techno Animal, Justin Broadrick and Kevin Martin opted for Ice to be a studio-based project. Drummer John Jobaggy and bassist Dave Cochrane were recruited to aid them in the recording process. Their debut album, Under the Skin, is comparable to Pure-era Godflesh and Martin's free jazz and dub work with God. The group went on hiatus for several years and Jobaggy was replaced by Laika drummer Lou Ciccotelli. By their second album, Bad Blood, the band had absorbed hip hop influences and nearly all the songs featured contributions from recognizable names in the underground rap scene. Blixa Bargeld, of Einsturzende Neubauten, also contributed his vocals to the music.
