AN ANALYSIS OF MILLENIAL SLANG WORDS FROM AMBER J.LIU” TWITTER ACCOUNT DATE SEPTEMBER 2020 – FEBRUARY 2021
This study aimed to investigate the types of slang that Amber J. Liu most often uses on her Twitter account. Slang is a language that has new value and is used by a specific group for a specific purpose, and is considered to be popular at the time and changes with the times. Therefore, this study aims to clarify the following research problem; what are millennial slang word and the types of slang were found in this study. The researcher used the descriptive qualitative method. The data of this research collected from Amber J. Liu in her Twitter account. The supporting instrument in this research is document analysis (screenshot) on tweet of Amber J. Liu Twitter wich contain slang words. The data collected from September 2020 until Februari 2021. The result show that there are 24 millenial slang. This research analyzed five types of slang words based on theory by Allan and Burridge cited in Putra. As a result, the types of slang words were 3 fresh and creative, 3 flippant, 1 imitative, 3 acronym, and 14 clipping
Comment on "The complete Schwarzschild interior and exterior solution in the harmonic coordinate system" [J. Math. Phys. 39, 6086 (1998)]
In a recent paper Liu considered the complete Schwarzschild interior and
exterior solution in harmonic coordinates. There he argued about the necessity
to keep an integration constant, in contrast with previous treatments. The
purpose of this comment is to show that the above conclusion cannot be traced
from the matching conditions between the vacuum exterior and the uniform
density interior perfect fluid, as claimed.Comment: 1999 paper, posted for on-line avalabilit
The Diatomic Molecular Spectroscopy Database: Data-science Driven Applications
Spectroscopic constants of molecules characterize the unique fingerprints of molecules and atoms. In particular, for diatomic molecules, spectroscopic constants encapsulate essential information about different applications in atomic, molecular, and optical physics, such as laser cooling or quantum information. To help find molecules well-suited for a given application, we have developed a database linked to an interactive website.\footnote{X. Liu, S. Truppe, G. Meijer and J. P\'{e}rez-R\'{i}os, J. Cheminform. \textbf{12}, 31 (2020)} The spectroscopic constants and Franck-Condon factors can be retrieved in useful formats from the website or via an application programming interface. New data can also be uploaded upon acceptance by the web managers.
By applying machine-learning approaches to this dataset, we show that the spectroscopic constants, including the equilibrium distance, harmonic vibrational frequency, and binding energy, are correlated and depend solely on the constituent's groups and periods. Based on these relationships, ground-state spectroscopic constants of polar diatomic molecules can be predicted with a relative error of , whereas the same properties for the A-excited electron state are predicted with an error of .\footnote{X. Liu, G. Meijer and J. P\'{e}rez-R\'{i}os, arXiv:2005.07913 (2020)} Anyone can make these predictions with access to our database, and it does not require any quantum chemistry knowledge.
Separately, we construct a database consisting of experimental electric dipole moments of 162 diatomic molecules. We show that the dipole moment of diatomic molecules is related to the constituent atoms' atomic properties, including electron affinity and ionization potential, and molecular properties that describe the force on the electrons at the equilibrium distance.\footnote{X.

Conservation laws can be derived from field equations?
Charge conservation law () usually is considered
as a corollary of Maxwell's equations. A circular reasoning, however, is found
in the derivation. A similar fallacy exists in the matter source's conservation
law () and Einstein's field equations. Therefore, the
source's conservation laws are NOT consequence of field equations.Comment: 2 page
On the -log-convexity conjecture of Sun
In his study of Ramanujan-Sato type series for , Sun introduced a
sequence of polynomials as given by
and he conjectured that the polynomials are -log-convex. By
imitating a result of Liu and Wang on generating new -log-convex sequences
of polynomials from old ones, we obtain a sufficient condition for determining
the -log-convexity of self-reciprocal polynomials. Based on this criterion,
we then give an affirmative answer to Sun's conjecture
Comment on 'A new nanoscale metastable iron phase in carbon steels'
We show that the selected area diffraction patterns presented in a recent
paper (T. Liu et al. Sci. Rep. 2015 5, 15331) do not prove the existence of a
new hexagonal phase in martensitic steels. They can be actually simulated by
twin effects.Comment: 5 pagesm 3 figure
