The h-index is an author-level metric that measures both the productivity and citation impact of the publications, initially used for an individual scientist or scholar. The h-index correlates with success indicators such as winning the Nobel Prize, being accepted for research fellowships and holding positions at top universities. [1]
The o-index corresponds to the geometric mean of the h-index and the most cited paper of a researcher. [30] RA-index: The RA-index accommodates improving the sensitivity of the h-index on the number of highly cited papers and has many cited paper and uncited paper under the h-core. This improvement can enhance the measurement sensitivity of the ...
refractive index: unitless principal quantum number: unitless amount of substance: mole: power: watt (W) active power (real power) watt (W) probability: unitless momentum: kilogram meter per second (kg⋅m/s) pressure: pascal (Pa) electric charge: coulomb (C) heat: joule (J) Reactive Power
Jorge Eduardo Hirsch (born 1953) is an Argentine American professor of physics at the University of California, San Diego. [1] Hirsch received a PhD in physics from the University of Chicago in 1980 and completed his postdoctoral research at the Kavli Institute for Theoretical Physics at the University of California, Santa Barbara in 1983.
Here h, k and ℓ are identical to the corresponding Miller indices, and i is a redundant index. This four-index scheme for labeling planes in a hexagonal lattice makes permutation symmetries apparent.
The henry (symbol: H) is the unit of electrical inductance in the International System of Units (SI). [1] If a current of 1 ampere flowing through a coil produces flux linkage of 1 weber turn, that coil has a self-inductance of 1 henry. The unit is named after Joseph Henry (1797–1878), the American scientist who discovered electromagnetic induction independently of and at about the same ...
Index funds work by matching — or tracking — the performance of a stock market index. An index is a group of stocks that share similar traits. For example, the S&P 500 index represents the 500 ...
The constants listed here are known values of physical constants expressed in SI units; that is, physical quantities that are generally believed to be universal in nature and thus are independent of the unit system in which they are measured.
