Materials Science
The pH response of liquid metal (eutectic GaInSn) in the form of a pendant
drop is investigated and the sensitivity of 92.96 mV in the pH range from 4 to
10 is obtained. Unlike the fundamental limit of pH sensitivity of 59.1 mV in an
electr...
Total coloring and efficient dominating sets of star transposition
graphs and pancake transposition graphs

Mathematics
Combinatorics
Let 0<k∈Z. Let the 2-set star transposition graph STk2 be
the (2k−1)-regular graph whose vertices are the 2k-strings on k symbols,
each symbol repeated twice, and each of whose edges is given by the
transposition of t...

We present a critical analysis of the classical approaches to energy
subjects, based on the work-energy theorem and the conservation of mechanical
energy proposed in the courses of the first years of tertiary education. We
show how these ap...

The emergence of unsupervised word embeddings, pre-trained on very large
monolingual text corpora, is at the core of the ongoing neural revolution in
Natural Language Processing (NLP). Initially introduced for English, such

Nuclear spins of noble gases exhibit exceptionally long coherence times and
can potentially serve as a long-lived storage medium for quantum information.
We analyze and compare the performance of two mechanisms for mapping the
quantum state...
Cosmological Constant Effect on Charged and Rotating Black Hole Shadows

Motivated by recent astrophysical observations, we investigate the shadow
behaviors of four dimensional charged rotating black holes with a cosmological
constant. This study is made in terms of a reduced moduli space parameterized
by the ch...

A commutative Noetherian ring R is said to be Tor-persistent if, for any
finitely generated R-module M, the vanishing of
ToriR(M,M) for i≫0 implies M has finite projective
dimension. An open question of Avram...

We study the out-of-equilibrium dynamics of one-dimensional quantum
Ising-like systems, arising from sudden quenches of the Hamiltonian parameter
g driving quantum transitions between disordered and ordered phases. In
