Cytolethal distending toxins (abbreviated CDTs) are a class of heterotrimeric toxins produced by certain gram-negative bacteria that display DNase activity.
 These toxins trigger G2/M cell cycle arrest in specific mammalian cell lines, leading to the enlarged or distended cells for which these toxins are named.
 Affected cells die by apoptosis.
Generally speaking, a calendar year begins on the New Year's Day of the given calendar system and ends on the day before the following New Year's Day, and thus consists of a whole number of days.
 A year can be measured by also starting on any other named day of the calendar, and end on the day before this named day in the following year.
 This may be termed as a "years time" but not in practice or an accepted means to term a Calendar year.
 To reconcile the calendar year with the astronomical cycle (which has a fractional number of days) certain years contain extra days.
The Love Express (German: Der Liebesexpreß) is a 1931 German musical comedy film directed by Robert Wiene and starring Georg Alexander, Dina Gralla and Joseph Schmidt.
 No print of the film is known to survive, and it is therefore a lost film.
 It is based on the operetta "Es lebe die Liebe" by Alexander Engel and Wilhelm Sterk.
 It was one of a cycle of operetta films made during the early sound era.
 A French-language version, "Venetian Nights" ("Nuits de Venise"), also directed by Wiene, was released the same year.
In physics, the Rabi cycle (or Rabi flop) is the cyclic behaviour of a two-level quantum system in the presence of an oscillatory driving field.
 A great variety of physical processes belonging to the areas of quantum computing, condensed matter, atomic and molecular physics, and nuclear and particle physics can be conveniently studied in terms of two-level quantum mechanical systems, and exhibit Rabi flopping when coupled to an oscillatory driving field.
 The effect is important in quantum optics, magnetic resonance and quantum computing, and is named after Isidor Isaac Rabi.
The Lacny or Lacny cycle is a chess problem theme named after Ľudovít Lačný, the first person to demonstrate the idea in 1949.
Pulsa D'Nura, Pulsa diNura or Pulsa Denoura (Aramaic: פולסי דנורא "lashes of fire") is a purportedly Kabbalistic ceremony in which the angels of destruction are invoked to block heavenly forgiveness of the subject’s sins, causing all the curses named in the Bible to befall him resulting in his death.
 However, the Torah prohibits praying that something bad should happen to another person .
 Rather it offers the solution to pray that the bad in the person die and he become a righteous person.
 The source for this modern ritual is not to be found in Kabbalah, but among the Hebrew magical manuals of antiquity, such as Sefer ha-Razim and Harba de-Moshe.
The hertz (symbol: Hz) is the derived unit of frequency in the International System of Units (SI) and is defined as one cycle per second.
 It is named for Heinrich Rudolf Hertz, the first person to provide conclusive proof of the existence of electromagnetic waves. Hertz are commonly expressed in multiples: kilohertz (10 Hz, kHz), megahertz (10 Hz, MHz), gigahertz (10 Hz, GHz), and terahertz (10 Hz, THz).
Isidor Isaac Rabi ( ; born Israel Isaac Rabi, 29 July 1898 – 11 January 1988) was an American physicist who won the Nobel Prize in Physics in 1944 for his discovery of nuclear magnetic resonance, which is used in magnetic resonance imaging.
 He was also one of the first scientists in the United States to work on the cavity magnetron, which is used in microwave radar and microwave ovens.
The Sonnets to Orpheus (German: Die Sonette an Orpheus ) are a cycle of 55 sonnets written in 1922 by the Bohemian-Austrian poet Rainer Maria Rilke (1875–1926).
 It was first published the following year.
 Rilke, who is "widely recognized as one of the most lyrically intense German-language poets," wrote the cycle in a period of three weeks experiencing what he described a "savage creative storm."
 Inspired by the news of the death of Wera Ouckama Knoop (1900–1919), a playmate of Rilke's daughter Ruth, he dedicated them as a memorial, or "Grab-Mal " (literally "grave-marker"), to her memory.
Picander's cycle of 1728–29 is a year cycle of church cantata librettos, published for the first time in 1728 as "Cantaten auf die Sonn- und Fest-Tage durch das gantze Jahr " (Cantatas for the Sun- and feastdays throughout the year).
 Johann Sebastian Bach set several of these librettos, but it is unknown whether he covered a substantial part of the cycle.
 This elusive cycle of cantata settings is indicated as the composer's fourth Leipzig cycle, or the "Picander cycle" (German: "Picander Jahrgang ").
