Non bis in idem
Non bis in idem (ne bis in idem), the double-jeopardy principle barring repeat trial or punishment for the same offence, as set out in the Rome Statute Article 20, ECHR Protocol No. 7 Article 4, ICCPR Article 14(7), and EU Charter Article 50.
Non built up area
Non built-up area: artificial land cover without buildings, defined in FAO LCCS by absence of natural cover and in LUCAS as class A20 (yards, cemeteries, parking, roads); distinct from non-urbanized vegetated areas.
Non Est Deus
Non Est Deus, Latin for "There is no God", is a German black metal band from Bamberg founded in 2017 by Noise, the musician also behind Kanonenfieber and Leiþa.
Non Non Biyori (のんのんびより)
Non Non Biyori (のんのんびより) is Atto's slice-of-life iyashikei manga about five students at rural Asahigaoka Branch School, serialized in Monthly Comic Alive 2009-2021, collected in 16 volumes, and adapted into a three-season Silver Link anime.

Non Nuoc Cao Bang UNESCO Global Geopark, in Cao Bang Province, northeastern Viet Nam, designated 2018 and revalidated 2022, covers 339,000 ha of tropical karst with Ban Gioc Waterfall, the Thang Hen lakes, and eight Indigenous communities.
Non paralytic strabismus
Non paralytic strabismus (ICD-11 9C80; concomitant strabismus) is eye deviation with full ocular movements in each eye, comitant in all gaze directions, comprising 75–95% of strabismus cases, treated with refractive correction, botulinum toxin, or surgery.
Non sequitur (literary device)
Non sequitur (Latin, "it does not follow"): a literary device in which a statement bears no logical relation to what precedes it, used for comedy, absurdism, and characterization; distinct from the non sequitur logical fallacy.
Non specific lipid transfer protein type 1 (par o 1)
Par o 1 is the major nsLTP (phospholipid-transfer protein) allergen of Parietaria officinalis pollen: a 13.5-14.5 kDa acidic glycoprotein, pI 4.6, with basic isoforms, dominant IgE epitopes, and limited cross-reactivity with food LTPs.
Non specific lipid transfer protein type 1 (pru p 3)
Pru p 3 is the major peach allergen, a lipid transfer protein concentrated in the peel that sensitizes most peach-allergic patients in the Mediterranean area.
Non-24 hour sleep-wake rhythm disorder
Non-24-hour sleep-wake syndrome (N24SWD), or free-running disorder, is a circadian rhythm sleep-wake disorder in which the clock fails to entrain to the 24-hour day, affecting 50-70% of totally blind people and causing daily sleep drift, cyclical insomnia, and daytime sleepiness.
Non-Abelian anyon
A non-Abelian anyon is a quasiparticle in a two-dimensional topological phase whose exchange applies a unitary matrix rather than a phase, the basis of topological quantum computation.
Non-Abelian band topology
Non-Abelian band topology is a branch of topological band theory in which multiband nodes carry non-commutative quaternion charges, making annihilation depend on the braiding path in momentum space.
Non-Abelian braiding
Non-Abelian braiding is the exchange of identical quasiparticles in a sequence whose final state depends on the order of the exchanges, so the operations do not commute.
Non-Abelian braiding of light
Non-Abelian braiding of light is the photonic realization of non-Abelian braiding, proposed in 2016 by Iadecola, Schuster, and Chamon and since demonstrated on photonic chips and in multimode fibers.
Non-Abelian frame charges
A non-Abelian frame charge is a topological invariant of band nodes in multiband systems, taking quaternion-group values so that braiding nodes changes their charges; first observed experimentally in 2021.
Non-abelian hidden subgroup problem
The non-abelian hidden subgroup problem asks a quantum computer to find a hidden subgroup of a finite non-commutative group, and no efficient general algorithm is known.
Non-Abelian synthetic gauge fields for ultracold atoms
Non-Abelian synthetic gauge fields for ultracold atoms are engineered laser-produced gauge potentials with non-commuting components that act on atoms' internal spin states, first proposed for optical lattices in 2005.
Non-Abelian topological charges of photonic bands
Non-Abelian topological charges of photonic bands are quaternion-valued labels that classify band degeneracies like nodal lines in multiband photonics, where the charges do not commute, so the order of loops changes the result.
Non-aggression pact
Non-aggression pact: a treaty in which states pledge not to use force against each other, distinct from neutrality pacts and alliances; emerged in the 1920s, exemplified by Molotov-Ribbentrop, and honored in war at the lowest rate of any alliance type (36.73%).
Non-aggression principle
Non-aggression principle (NAP), also called nonaggression axiom, libertarian rule forbidding initiation of force against person or property; codified by Murray Rothbard in For a New Liberty (1973), grounded in self-ownership, criticized by Zwolinski, contested on immigration.
Non-Aligned Movement
Non-Aligned Movement (NAM), also called the Movement of Non-Aligned Countries: forum of developing states founded at the 1961 Belgrade summit after the 1955 Bandung Conference, seeking independent foreign policy outside the US and Soviet blocs, with no charter or permanent secretariat.
