The Uniqueness Theorem for Entanglement Measures

open access: yes, 2002
We explore and develop the mathematics of the theory of entanglement measures. After a careful review and analysis of definitions, of preliminary results, and of connections between conditions on entanglement measures, we prove a sharpened version of a ...

On Okamura’s uniqueness theorem [PDF]

open access: yesProceedings of the American Mathematical Society, 1967
Moyer [1] gives a uniqueness theorem for ordinary differential equations which includes many of the known criteria for uniqueness. It is demonstrated here that Mloyer's results can be obtained as a special case of Okamura's theorem [2]. (See Yoshizawa, [3].) If f (t, y) is defined and continuous on D: to< t < to +a, I y-yo 1 5b, the problem of ...

Gapless Superconductivity From Extremely Dilute Magnetic Disorder in 2H‐NbSe2‐xSx

open access: yesAdvanced Materials, EarlyView.
We demonstrate that 2H‐NbSe2‐xSx hosts gapless superconductivity at unexpectedly low magnetic impurity concentrations. Combining STM, Bogoliubovde Gennes simulations, DFT, and quasiparticle interference, we comprehensively study the development of gapless behavior and show that SeS substitution reshapes the band structure, enhances nesting, and drives ...

A Correlation Between Solutions of Uncertain Fractional Forward Difference Equations and Their Paths

open access: yesFrontiers in Physics, 2020
We consider the comparison theorems for the fractional forward h-difference equations in the context of discrete fractional calculus. Moreover, we consider the existence and uniqueness theorem for the uncertain fractional forward h-difference equations ...

Plasmonic Nanomachines: Creating Local Potential Gradients and Motions

open access: yesAdvanced Materials, EarlyView.
Plasmonic nanomachines can generate optical, thermal, and chemical potential gradients to drive directional rectilinear, rotational, and twisting motions at the nanometer scale. The integration of multimodal plasmonic forces with functional materials and programmed structural distortions enables precise spatiotemporal actuation, thereby providing a ...

Uniqueness theorem for p-biharmonic equations

open access: yesElectronic Journal of Differential Equations, 2002
The goal of this paper is to prove existence and uniqueness of a solution of the initial value problem for the equation $$ (|u''|^{p-2}u'')''=lambda |u|^{q-2}u $$ where $lambdain{mathbb{R}}$ and $p,q>1$. We prove the existence for $pgeq q$ only, and give

Almost-periodic solution for BAM neural networks [PDF]

open access: yesSurveys in Mathematics and its Applications, 2009
In this paper, we study the existence and uniqueness solution and investigate the conditions that make it almost-periodic solution for BAM neural networks with retarded delays.

Waveguide Photoactuators: Materials, Fabrication, and Applications

open access: yesAdvanced Robotics Research, EarlyView.
Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...
