Fractional-conformable control for cooperative object transport in multi-robot systems

Results in Engineering
This paper proposes a decentralized control framework for cooperative object transport in a multi-robot system (MRS) composed of two omnidirectional robots and one object. The approach integrates Conformable Fractional Functions (CFF) within a fractional-

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

Advanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Value Distribution and Uniqueness Results of Zero-Order Meromorphic Functions to Their q-Shift

Discrete Dynamics in Nature and Society, 2012
We investigate value distribution and uniqueness problems of meromorphic functions with their q-shift. We obtain that if f is a transcendental meromorphic (or entire) function of zero order, and Q(z) is a polynomial, then afn(qz)+f(z)−Q(z) has infinitely

On the polynomiality of separately constant functions

Carpathian Mathematical Publications, 2014
Изучается, каким необходимым и каким достаточным условиям должно удовлетворять подмножество $E$ числовой плоскости $\mathbb R^2$ для того, чтобы каждая раздельно постоянная функция $f : E \to\mathbb R$ была полиномиальной и вместе с тем существовала раздельно постоянная и непостоянная функция $f_0 : E \to\mathbb R$.

The Proof of the Structure Stability of the Polynomial Curve Fitting Model When the Time Variable t Takes Equidistant Values

Journal of Mathematics
The polynomial curve fitting models are among the most common trend extrapolation prediction models. The time-independent variable t=t1,t2,⋯,tnT can take on various values during model construction, and it is a theoretical question whether different ...

Structural and Compositional Effects on the Scintillation Properties of Fast Emitting Metal‐Organic Frameworks

Advanced Science, EarlyView.
The crystalline structure, the atomic numbers of the constituent elementsand the size of MOF crystals each influence their photoluminescence and scintillation properties in distinct ways. Together, these factors provide valuable guidelines for designing systems with optimized performance and tunable timing characteristics, arising from the synergistic ...

Femtosecond‐Laser Nanocavitation Regenerates SERS‐Active Plasmonic Nanogaps for Longitudinal Molecular Sensing at Biointerfaces

Advanced Science, EarlyView.
A regenerative molecular sensing platform that co‐localizes surface‐enhanced Raman spectroscopy (SERS) sensing and nanocavitation‐based actuation. Femtosecond‐laser triggered nanocavitation produces thermomechanical forces to locally regenerate SERS‐active nanogaps in protein‐rich biofluids while preserving optical performance.

Unboundedness of the Lipschitz Constants of Best Polynomial Approximation

Journal of Approximation Theory, 2000
This paper is a proof of a single noteworthy theorem that confirms a conjecture of \textit{M. S. Henry} and \textit{J. A. Roulier} [J. Approximation Theory 22, 85-94 (1978; Zbl 0428.41003)]. For \(f\in C[-1,1]\), let \(q_n(f)\) be the best uniform approximation to \(f\) from \(P_n\) -- the algebraic polynomials of degree \(n\) or less. It is known that
