International Journal of Quantum Chemistry, Volume 126, Issue 13, July 5, 2026.During optimization via the quantum natural gradient in a variational quantum eigensolver, the evolution of the Fubini‐Study metric suppresses irrelevant parameter directions and reduces state distinguishability near the ground state. ABSTRACT The lack of both a consistently effective and broadly reliable classical optimizer for variational quantum ...

Well-posedness of elliptic-parabolic differential problem with integral condition
Қарағанды университетінің хабаршысы. Математика сериясыIn this paper, we study a class of nonlocal boundary value problems for elliptic-parabolic equations subject to integral-type conditions. Such problems naturally emerge in various physical and engineering contexts, including diffusion processes in ...

A nonlocal boundary value problem with singularities in phase variables
Mathematical and Computer Modelling, 2004 Sufficient conditions for the solvability are obtained for the second-order nonlinear boundary value problem \[ (g(x'(t)))'=f(t,x(t)),\;x'(t)),\quad x(0)=x(T)=-\gamma\min\{x(t): t\in[0,T]\}. \] Here, \(g\) is a continuous increasing odd function. The right-hand side \(f(t,x,x')>0\) may be singular both at \(x=0\) and \(x'=0\).

Data‐Efficient Electromagnetic Surrogate Solver Through Dissipative Relaxation Transfer Learning
Advanced Optical Materials, Volume 14, Issue 25, 3 July 2026.Dissipative relaxation transfer learning (DIRTL) enables data‐efficient training of electromagnetic surrogate solvers by pretraining data generated with artificial material loss before fine‐tuning on target lossless data. The framework suppresses resonant outlier effects during early training, allowing effective adaptation to high‐amplitude resonances ...

Natural Sciences, Volume 6, Issue 3, July 2026.Within quantum chemistry, density functional theory (DFT) is a revolution. This serves as an example of a multitude of other scientific events, supporting the idea that revolutions are always large, if observed with the appropriate magnification. ABSTRACT Distinguishing scientific revolutions from normal science is a subjective, conflicting matter ...
