Double-stranded RNA
Double-stranded RNA (dsRNA) is ribonucleic acid with two complementary base-paired strands. Made during viral replication, it triggers RNA interference, the gene-silencing pathway, and innate immune defenses.
Double-well potential
A double-well potential is a potential energy function with two minima separated by a barrier, used in quantum mechanics to model tunneling between two classically distinct configurations.
Double-Weyl fermions in SrSi2
Double-Weyl fermions in SrSi2 is a 2016 prediction that strontium disilicide, a chiral cubic compound, hosts Weyl nodes with double topological charge; experiments later found a narrow-gap semiconductor.
Doubling time
Doubling time, also called doubling period, is the time an exponentially growing quantity needs to double, given by ln 2 divided by the growth rate.
Doubly charmed baryon
A doubly charmed baryon is a baryon containing two charm quarks, giving charm quantum number C = +2. The Ξcc++ was first observed by LHCb in 2017 at about 3621 MeV.
Doubly heavy baryon
A doubly heavy baryon is a baryon with two heavy quarks of one flavor, either charm or bottom, plus one light quark; the doubly charmed Ξcc++ was observed by LHCb in 2017.
Doubly magic nucleus
A doubly magic nucleus is an atomic nucleus in which both protons and neutrons have magic numbers, forming closed shells; examples include helium-4, calcium-48, and lead-208.
Doubly robust estimation
Doubly robust estimation is a statistical method for estimating causal effects or means with missing data, remaining unbiased if either the outcome model or the propensity model is correct.
Doubly special relativity
Doubly special relativity, also called deformed special relativity, is a class of proposed modifications of special relativity with two invariant scales: the speed of light and the Planck energy.
Doubly stochastic matrix
A doubly stochastic matrix, also called a bistochastic matrix, is a square matrix of nonnegative numbers in which every row and every column sums to 1.
