CO2 Storage Site Selection: A Comprehensive Review of Current Approaches
Greenhouse Gases: Science and Technology, EarlyView.ABSTRACT Global warming, driven by increasing anthropogenic greenhouse gas emissions, has emerged as a critical environmental concern. Carbon capture and storage (CCS) technology offers a promising solution for reducing CO2 emissions, but its effectiveness depends on identifying suitable candidates that can ensure safe, long‐term storage of CO2.

A Learning Model with Memory in the Financial Markets
International Journal of Finance &Economics, EarlyView.ABSTRACT Learning is central to a financial agent's aspiration to gain persistent strategic advantage in asset value maximisation. The implicit mechanism that transforms this aspiration into an observed value gain is the speed of error corrections (demonstrating, an agent's speed of learning) whilst facing increased uncertainty.

Commuting Pairs in Quasigroups
Journal of Combinatorial Designs, EarlyView.ABSTRACT A quasigroup is a pair (Q,∗) $(Q,\ast )$, where Q $Q$ is a nonempty set and ∗ $\ast $ is a binary operation on Q $Q$ such that for every (a,b)∈Q2 $(a,b)\in {Q}^{2}$, there exists a unique (x,y)∈Q2 $(x,y)\in {Q}^{2}$ such that a∗x=b=y∗a $a\ast x=b=y\ast a$. Let (Q,∗) $(Q,\ast )$ be a quasigroup. A pair (x,y)∈Q2 $(x,y)\in {Q}^{2}$ is a commuting

Develop Coding Operations by Improving Applications of Matrix Algebra in Cross Mathematical Notation
International Journal of Intelligent Systems and Applications in Engineering, 2023 Currently encryption methods are much more sophisticated , among them the most used is the RSA algorithm, created by Rivest, Shamir, Adleman pblished in 1977 in the journal Scientific American, based on prime numbers of great magnitude, the which uses the model of a public and a private key (asymmetric encryption) .

Modelling the drying of single droplets of aqueous solutions of lactose and of maltodextrin
Journal of Chemical Technology &Biotechnology, EarlyView.Abstract The average temperature of shrinking droplets is obtained from an enthalpy balance considering convection to or from the surroundings and cooling due to evaporation of solvent from the surface. This unique application of the fully implicit backward scheme captures the moisture values at all nodes in the grid, including at the centre and outer ...

A Dichotomy Theorem for Γ ${\rm{\Gamma }}$‐Switchable H $H$‐Colouring on m $m$‐Edge‐Coloured Graphs
Journal of Graph Theory, EarlyView.ABSTRACT Let G $G$ be a graph in which each edge is assigned one of the colours 1,2,…,m $1,2,\ldots ,m$, and let Γ ${\rm{\Gamma }}$ be a subgroup of Sm ${S}_{m}$. The operation of switching at a vertex x $x$ of G $G$ with respect to an element π $\pi $ of Γ ${\rm{\Gamma }}$ permutes the colours of the edges incident with x $x$ according to π $\pi $. We

Global and microlocal aspects of Dirac operators: Propagators and Hadamard states
Mathematische Nachrichten, EarlyView.Abstract We propose a geometric approach to construct the Cauchy evolution operator for the Lorentzian Dirac operator on Cauchy‐compact globally hyperbolic 4‐manifolds. We realize the Cauchy evolution operator as the sum of two invariantly defined oscillatory integrals—the positive and negative Dirac propagators—global in space and in time, with ...

A fractional‐order trace‐dev‐div inequality
Mathematische Nachrichten, EarlyView.Abstract The trace‐dev‐div inequality in Hs$H^s$ controls the trace in the norm of Hs$H^s$ by that of the deviatoric part plus the Hs−1$H^{s-1}$ norm of the divergence of a quadratic tensor field different from the constant unit matrix. This is well known for s=0$s=0$ and established for orders 0≤s≤1$0\le s\le 1$ and arbitrary space dimension in this ...

Heisenberg‐smooth operators from the phase‐space perspective
Mathematische Nachrichten, EarlyView.Abstract Cordes' characterization of Heisenberg‐smooth operators bridges a gap between the theory of pseudo‐differential operators and quantum harmonic analysis (QHA). We give a new proof of the result by using the phase‐space formalism of QHA. Our argument is flexible enough to generalize Cordes' result in several directions: (1) we can admit general ...

Mathematical Methods in the Applied Sciences, EarlyView.We develop a full randomization of the classical hyper‐logistic growth model by obtaining closed‐form expressions for relevant quantities of interest, such as the first probability density function of its solution, the time until a given fixed population is reached, and the population at the inflection point.
