The standard acceleration of gravity or standard acceleration of free fall, often called simply standard gravity and denoted by ɡ0 or ɡn, is the nominal gravitational acceleration of an object in a vacuum near the surface of the Earth. It is a constant defined by standard as 9.806 65 m/s 2 (about 32.174 05 ft/s 2).

Graham's number is an immense number that arose as an upper bound on the answer of a problem in the mathematical field of Ramsey theory. It is much larger than many other large numbers such as Skewes's number and Moser's number, both of which are in turn much larger than a googolplex.

The G0 phase describes a cellular state outside of the replicative cell cycle. Classically [when?], cells were thought to enter G 0 primarily due to environmental factors, like nutrient deprivation, that limited the resources necessary for proliferation.

G0/G1期：G1期，细胞体积逐渐增大，细胞开始RNA和蛋白质的合成，DNA含量保持二倍体状态，G0期是脱离细胞周期暂时停止分裂的一个阶段。 但在一定适宜刺激下，又可进入周期，从DNA含量上无法区分G0与G1期； S期：在这一阶段完成DNA的合成以及合成与DNA组装构成染色质等有关的组蛋白。 DNA含量在此时期增加，介于G1期和G2期之间； G2/M期：G2期是DNA复制结束和开始有丝分裂之间的间隙。 从DNA含量上同样无法区分G2期和M期。 检测细胞周期最 …

2023年5月23日 · We show that G0 arrest preferentially emerges in the context of more stable, less mutated genomes which maintain TP53 integrity and lack the hallmarks of DNA damage repair deficiency, while presenting increased APOBEC mutagenesis.

2024年7月30日 · G0期（G zero phase）：在这个阶段，细胞暂时停止了分裂和DNA复制，并进入了休眠状态。 通常情况下，细胞会进入G0期来完成特定的功能或维持生存，如细胞分化、代谢调节或修复受损的DNA。

2025年2月8日 · The G0 phase, known as the quiescent stage, is a state where cells temporarily or permanently exit the active cycle. Unlike G1, S, G2, and M phases, which involve cell …

The G0 phase (referred to the G zero phase) or resting phase is a period in the cell cycle in which cells exist in a quiescent state. G0 phase is viewed as either an extended G1 phase, where...

Graham's number is commonly celebrated as the largest number ever used in a serious mathematical proof, although much larger numbers have since claimed this title (such as TREE (3) and SCG (13)). The smallest Bowersism exceeding Graham's number is corporal, and the smallest Saibianism exceeding Graham's number is graatagold.

other markers to distinguish G0 from G1 cells exist. The first such marker was shown to be cellular RNA content, or number of ribosomes per cell: quiescent, G0 cells, contain on average 10 times fewer ribosomes compared to cycling G1 cells (e.g. Stanners et al., J. Cell Physiol, 11: 127, 1979), and much less of total RNA, as measured by
