Comet: Fine-grained Computation-communication Overlapping for Mixture-of-Experts
Conference on Machine Learning and SystemsMixture-of-experts (MoE) has been extensively employed to scale large language models to trillion-plus parameters while maintaining a fixed computational cost.

The enzyme-modified comet assay: past, present and future.
Food and Chemical Toxicology, 2020The enzyme-modified comet assay was developed in order to detect DNA lesions other than those detected by the standard version (single and double strand breaks and alkali-labile sites).

The solution of the statistical equilibrium equations for the SO molecule is used to estimate the expected intensities of microwave lines. The observed fluxes of the microwave lines of SO in Comet Hale–Bopp require approximately 1.8 1028 mol/sec which give fluxes in the A3Π - X3Σ−bands below the observable limit, consistent with the observations.

Evidence of ammonium salts in comet 67P as explanation for the nitrogen depletion in cometary comae
Nature Astronomy, 2019Cometary comae are generally depleted in nitrogen. The main carriers for volatile nitrogen in comets are NH 3 and HCN. It is known that ammonia readily combines with many acids, such as HCN, HNCO and HCOOH, encountered in the interstellar medium as well ...

Combinatorial optimization problems naturally arise in many application areas, including logistics, manufacturing, supply-chain management, and resource allocation. They often give rise to complex and intricate programs, because of their inherent computational and software complexity.

A diagram is presented showing how the Rosetta spacecraft of the European Space Agency will carry out its mission of orbiting Comet 76P/Churyumov-Gerasimenko then sending a lander to the comet's surface from August 2014 through December 2015.

Puzzling changes in the orbital period of Comet Encke, which circles the sun every 3.3 years, can be attributed to the rotation of its icy nucleus and the thrust of gases evaporated from it.

Annual Review of Astronomy and Astrophysics, 1987
Recent theoretical and observational studies of comets are reviewed, with an emphasis on in situ data from spacecraft encounters with P/Giacobini-Zinner (September 1985) and P/Halley (March 1986). Topics addressed include clues on the origin and permanence of the Oort cometary cloud, observations of cometary nuclei far from the sun, the Halley nucleus,

Recent advances in cometary science have indicated the importance of mixing of materials in the disk where the planets of our solar system formed. Now, the results from the Stardust Discovery Mission unambiguously show that even more extensive and earlier mixing of the material took place, raising new challenges for theories of the protoplanetary disk ...
