Quantum Time‐Marching Algorithms for Solving Linear Transport Problems Including Boundary Conditions
International Journal for Numerical Methods in Engineering, Volume 127, Issue 8, 30 April 2026.ABSTRACT This article presents the first complete application of a quantum time‐marching algorithm for simulating multidimensional linear transport phenomena with arbitrary boundaries, whereby the success probabilities are problem intrinsic. The method adapts the linear combination of unitaries algorithm to block encode the diffusive dynamics, while ...

Spiral cutoff-flow of quantum quartic oscillator
Nuclear Physics BTheory of the quantum quartic oscillator is developed with close attention to the cutoff one needs to impose on the system in order to approximate the smallest eigenvalues and corresponding eigenstates of its Hamiltonian by diagonalizing matrices of ...

Spectroscopic Investigation of Thioacrolein by Variational and Perturbational Approaches
Journal of Computational Chemistry, Volume 47, Issue 10, 15 April 2026.The vibrational and rotational spectra of trans and cis‐thioacrolein were studied by high levels of electronic and vibrational structure theory. Comparisons with experimental results are provided for several molecular quantities. ABSTRACT The vibrational spectra of trans and cis‐thioacrolein have been studied by 2nd order vibrational perturbation ...

Maximum Entropy Probability Density Principle in Probabilistic Investigations of Dynamic Systems
Entropy, 2018 In this study, we consider a method for investigating the stochastic response of a nonlinear dynamical system affected by a random seismic process. We present the solution of the probability density of a single/multiple-degree of freedom (SDOF/MDOF ...

Time-Free Solution to Hamilton Path Problems Using P Systems with d-Division
Journal of Applied Mathematics, 2013 P systems with d-division are a particular class of distributed and parallel computing models investigated in membrane computing, which are inspired from the budding behavior of Baker’s yeast (a cell can generate several cells in one reproducing cycle ...

New classes of polynomial maps satisfying the real Jacobian conjecture in ℝ2
Anais da Academia Brasileira de Ciências: We present two new classes of polynomial maps satisfying the real Jacobian conjecture in ℝ 2. The first class is formed by the polynomials maps of the form (q(x)–p(y), q(y)+p(x)) : R 2 ⟶ R 2 such that p and q are real polynomials satisfying p'

Symmetries of the garnier system and of the associated polynomial Hamiltonian system
Proceedings of the Japan Academy, Series A, Mathematical Sciences, 1990 For a completely integrable Pfaffian system \[ E(\theta):\;dx_ i=\sum^{n}_{j=1}G_{ij}(x,t,\theta)dt_ j,\quad G_{ij}\in {\mathbb{C}}(x,t),\quad i=1,...,m \] depending on parameters \(\theta \in {\mathbb{C}}^ N\), a symmetry for E(\(\theta\)) is a pair (S,l) of a birational transformation S: (x,t)\(\to (x',t')\) and an affine transformation l: \({\mathbb{
