The impact factor (average number of citations per paper) for the Astrophysical Journal Supplement Series jumped between 2003 and 2004 from 6.247 to 15.231, giving it the world's second highest impact factor for an astronomical journal in 2004. Was this change due to a computing error or to ...
here and in these proceedings are demonstrating the status and continuous progress of data analyses and their theoretical descriptions, as well as highlighting the experimental and theoretical outlook of what shall and may be achieved in the new era of the 12-GeV upgraded transition form factor ...
Bengt Strmgren - 《Astrophysical Journal》 被引量: 282发表: 1948年 Characterization of the transcription activation function and the DNA binding domain of transcriptional enhancer factor-1. The regions of transcriptional enhancer factor-1 (TEF-1) required for its activation function and sequence-specif...
𝑆2S2 is a dimensionless conformal scale factor. By performing the coordinate transformation as: 𝑑𝑠2=−(𝐴(𝜆)+2𝐴(𝜆)Ω2(𝜆,𝓇))𝑐2𝑑𝑡2+(𝐵(𝜆)+2𝐵(𝜆)Ω2(𝜆,𝓇))𝑑𝜆2+𝜆2𝑑𝜃2+𝜆2𝑠𝑖𝑛2𝜃 𝑑𝜙2ds2=−Aλ+2AλΩ2λ...
The cross section for ionization from the vibrational level v″ of the neutral molecule to a vibrational level v′ in the ionized molecule is given by the Franck–Condon factor (FCF) which is equal to the square of the overlap integral between the respective vibrational wavefunctions, i.e. ...
To that end, SpaceX started adding visors to its satellites to reduce the brightness of the reflection. The team investigated the effectiveness of visors and found that with the ZTF observations, the attachment reduced a satellite’s brightness by a factor of about five — a level that fails ...

It's a surprise to see a tiny change from the bottom level could have significant impact on the whole system. The research on change analysis will finally benefit the complexity measurement as an influence factor of metrics. 展开 关键词: Complex system Change management Change taxonomy Impact ...
In a reportreleased in October 2022, the American Astronomical Society (ASS) likened the impact of megaconstellations onastronomyto light pollution. The report said the sky may brighten by a factor of two to three due to the diffuse reflection of sunlight off the spacecraft. ...
The mass distributions of MSPs and the less recycled pulsars could be fitted by a Gaussian function as 1.45±0.42 M⊙ and 1.31±0.17 M⊙ (with 1σ) respectively. As such, the MSP masses are heavier than those in less recycled systems by factor of ~ 0.13M⊙, since the accretion effect ...
