Purpose: This paper demonstrates that the numerical method is not everything for nonlinear equations. Some properties cannot be revealed numerically, an example is used to elucidate the fact. Design/methodology/approach: A variational principle is established for the generalized KdV-Burgers equation by...

We examine a family of integrable differential-difference equations and obtain their non-autonomous extensions using a discrete/continuous integrability criterion. Introduction Integrable deautonomization of difference equations have been the object of intensive studies these past few years, in particular in...

the larger the share of wealth concentrated in the hands of a few and the greater the difference between the share of the total number and the share of acquired income. The ratio between the two is an indicator of uneven distribution and can be represented graphically (by the so-called Lore...
In particular, this paper uses a rich collection of household surveys to address the following three questions: (i) Is there a significant difference between public and private sector wages? (ii) Do the public and private sectors discriminate against women? (iii) Is the gender wage gap bigger...
. Similarly, ensemble inference has let Orbitrap QE-HFX (FG_DDA_qe_ens) to catch up with the performance of TimsTOF pro (FG_DDA_tims) in detecting TPs (2104 vs. 2556, Fig.5d). In addition, FG_DDA_ens (3096) detected similar numbers of TPs compared to spt_DIA (3102) and spt_DIA...
finally, the derivative of the function will be displayed in the new window what is meant by differential equations? in mathematics, the differential equation is an equation, which contains one or more derivatives of a function. in other words, the equation contains one or more dependent ...
