DYN (magazine)
''DYN'' (derived from the Greek word ''κατὰ τὸ δυνατόν'', ''that which is possible'') was an art magazine founded by the Austrian-Mexican Surrealist Wolfgang Paalen, published in Mexico City, and distributed in New York City, and London between 1942 and 1944. Only six issues were produced. Background With his journal Paalen in his work as ''editeur'' gave himself the opportunity to fully develop his intellectual abilities with the evident but nevertheless for himself surprising result that he temporarily advanced to one of the most influential art theorists during the war. In seven large essays and countless smaller articles and reviews he discussed in detail all current hot topics that also concerned the young artists in New York, and in response received their full attention: the new image as potential picture-being; morality, deliberated of Marxist means-end thinking; plastic automatism—deliberated of the bondage of preconceived literary contents; dialectica ...

Dyne
The dyne (symbol: dyn; ) is a derived units of measurement, unit of force (physics), force specified in the centimetre–gram–second system of units, centimetre–gram–second (CGS) system of units, a predecessor of the modern International System of Units, SI. History The name dyne was first proposed as a CGS unit of force in 1873 by a Committee of the British Association for the Advancement of Science. Definition The dyne is defined as "the force required to accelerate a mass of one gram at a rate of one centimetre per second squared". An equivalent definition of the dyne is "that force which, acting for one second, will produce a change of velocity of one centimetre per second in a mass of one gram". One dyne is equal to 10 micronewtons, 10−5 newton (unit), N or to 10 nsn (nanosthenes) in the old metre–tonne–second system of units. * 1 dyn = 1 g⋅cm/s2 = 10−5 kg⋅m/s2 = 10−5 N * 1 N = 1 kg⋅m/s2 = 105 g⋅cm/s2 = 105 dyn Use The dyne per centimetr ...

Dyn (company)
Dyn, Inc. () was an Internet performance management company that also dealt with web application security, offering products to monitor, control, and optimize online infrastructure, and also domain registration services and email products. The company was acquired by Oracle Corporation in 2016. It began operating as a global business unit of Oracle in 2017. History Dyn was created as a community-led student project by Tim Wilde during his undergraduate studies at Worcester Polytechnic Institute. Eventually, Wilde, the founder, brought in Jeremy Hitchcock and Tom Daly as partners. Dyn enabled students to access lab computers and print documents remotely. The project then moved toward Domain Name System (DNS) services. The first iteration was a free donation-based dynamic DNS service known as DynDNS. The project required $25,000 to stay open and raised over $40,000. The donation-based model continued until 2002 and ended with a launch of "donator-only" DNS services. Later, a ...

Dynorphin
Dynorphins (Dyn) are a class of opioid peptides that arise from the precursor protein prodynorphin. When prodynorphin is cleaved during processing by proprotein convertase 2 (PC2), multiple active peptides are released: dynorphin A, dynorphin B, and α/ β-neoendorphin. Depolarization of a neuron containing prodynorphin stimulates PC2 processing, which occurs within synaptic vesicles in the presynaptic terminal. Occasionally, prodynorphin is not fully processed, leading to the release of "big dynorphin". "Big dynorphin" is a 32-amino acid molecule consisting of both dynorphin A and dynorphin B. Dynorphin A, dynorphin B, and big dynorphin all contain a high proportion of basic amino acid residues, in particular lysine and arginine (29.4%, 23.1%, and 31.2% basic residues, respectively), as well as many hydrophobic residues (41.2%, 30.8%, and 34.4% hydrophobic residues, respectively). Although dynorphins are found widely distributed in the CNS, they have the highest concentra ...

Nira Dyn
Nira (Richter) Dyn (; born 1942) is an Israeli mathematician who studied geometric modeling, subdivision surfaces, approximation theory, and image compression. She is a professor emeritus of applied mathematics at Tel Aviv University, and has been called a "pioneer and leading researcher in the subdivision community". Education and career Dyn earned a bachelor's degree from the Technion – Israel Institute of Technology in 1965. She went on to graduate study at the Weizmann Institute of Science, where she earned a master's degree in 1967 and completed her doctorate in 1970. Her dissertation, ''Optimal and Minimum Norm Approximations to Linear Functionals in Hilbert Spaces, and their application to Numerical Integration'', was supervised by Philip Rabinowitz. After postdoctoral research in the Institute of Fundamental Studies at the University of Rochester, she joined the Tel Aviv faculty in 1972, and retired in 2010. Recognition Dyn was an invited speaker at the 2006 Internation ...
