Not only have we reduced the length of the quadrupole while maintaining ion transmission efficiency, we have included patented configuration switching, meaning the quadrupoles stay cleaner for longer. In addition,...
Structure, stability, electronic structure, spectroscopy and chemical bonding properties of a fluorine atom doped gas-phase small to medium-sized magnesium clusters, FMgn (n = 2–20), systematically investigated by CALYPSO software together with density functional theory (DFT). Structural calculatio...
When genomic data for a particular organism are either unavailable or of insufficient quality, de novo sequencing (meaning “from the beginning”) is a method of building or updating the reference genome. Although a whole-genome...

the identification of the characteristic peak components in the characteristic map, meaning the determination of other active components with a single component or the content of the internal standards, and a quality control standard for the absolute or relative quantification of multiple indicators (Fig...
Parameters such as gas content (GAS), porosity (PHI) and total organic carbon (TOC) are key parameters that reveal the shale gas geological “sweet spot” of reservoirs. However, the lack of a three-dimensional high-precision prediction method is not conducive to large-scale exploration of sha...
meaning implementation factors heavily influence the assessment and effectiveness of instruments. In this perspective, we provide a technical but accessible introduction to the background of a few common drug checking methods aimed at current and potential drug checking service providers. We discuss the ...
This sign was first given its current mathematical meaning in "Arithmetica Infinitorum" (1655) by the British mathematician John Wallis (1616-1703). +¥(resp.-¥) is the mathematical symbol used to denote the "limit" of a real quantity thateventuallyremains above (resp. below)anypreset bo...

Firstly, the current process of researching ROP prediction and optimization is offline, meaning that model training and optimization are based on historical data collection. Such models cannot provide guidance for on-site operations. Secondly, drilling sequences contain a wealth of information, such as...
