Quadratically converging rational mean iterations
Journal of Mathematical Analysis and Applications, 1991 Several examples of mean iterations (mixing algorithms of means: \(a_{n+1}=M_ 1(a_ n,b_ n),\) \(b_{n+1}=M_ 2(a_ n,b_ n);\) \(n=0,1,2,...;\) in addition to the usual properties of means, also homogeneity \(M_ k(\lambda x,\lambda y)=\lambda M_ k(x,y),\quad k=1,2,\) is supposed) with quadratic convergence \((| a_{n+1}- b_{n+1}| =0(| a_ n-b_ n|^ 2))\) are ...

Advanced Optical Materials, EarlyView.Molecular crystals must withstand both isotropic and anisotropic stress to function in flexible optoelectronics and high‐pressure devices. In situ high‐pressure single‐crystal X‐ray diffraction coupled with DFT‐D computations reveal how an emissive molecular crystal with interdigitated packing bends elastically at ambient‐pressure and remains ...

On the density of generalised quadratic forms with applications to asymptotic expansions for test statistics [PDF]
In this note we derive a general formula useful to express the density of generalised noncentral quadratic forms (i.e. of a scalar random variable obtained by contracting non zero mean multivariate normal vectors over multidimensional arrays) in terms of

Mean Values of Quadratic Twists of AutomorphicL-functions
Journal of Number Theory, 1996 Let \(\pi\) be a cuspidal irreducible unitary representation of GL\((r,\mathbb{A}_{\mathbb{Q}})\) which satisfies Ramanujan's conjecture (tempered local components). Assume \(L_f(s,\pi\otimes\chi)\) (``\(f\)'' for ``finite'') satisfies the generalized Riemann hypothesis for all Dirichlet characters \(\chi\) modulo a fixed prime \(q\).

Advanced Optical Materials, EarlyView.It is demonstrated that in chiral ferroelectric nematic liquid crystals sandwiched between electrically conducting transparent plates, the reflection color can be reversibly tuned by electric fields applied along the helix axis. The proposed theoretical model, assuming field‐induced coiling of the helix axis, accounts for all observations.

Nuclear Physics BThe interaction problem between solitons and mean flows including the dispersive shock wave, rarefaction wave, kink and contact dispersive shock wave, is discussed in the framework of the Gardner equation, a generic non-convex mathematical model ...

On the Computation of Optimal Monotone Mean-Variance Portfolios via Truncated Quadratic Utility [PDF]
We report a surprising link between optimal portfolios generated by a special type of variational preferences called divergence preferences (cf. [8]) and optimal portfolios generated by classical expected utility.

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review
Advanced Robotics Research, EarlyView.Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.
