Advanced Materials, EarlyView.This work reports a direct, biocompatible method to synthesize UiO‐66, enabling one‐step encapsulation of proteins without compromising crystallinity or activity. Using advanced in situ and ex situ techniques, the study reveals that proteins integrate concurrently with MOF growth, forming crystalline protein@UiO‐66 nanoparticles, and provide insight ...

Stability in Terms of Two Measures for Nonlinear Impulsive Systems on Time Scales
Journal of Applied Mathematics, 2013 We investigate some stability problems in terms of two measures for nonlinear dynamic systems on time scales with fixed moments of impulsive effects. Sufficient conditions for (uniform) stability, (uniform) asymptotic stability, and instability in terms ...

Optimizing nonlinear adaptive control allocation [PDF]
Modeling, Identification and Control, 2006 A control-Lyapunov approach is used to develop an adaptive optimizing control allocation algorithm for over-actuated mechanical systems where the actuator model is affine in the uncertain parameters. Uniform global (asymptotic) stability is guaranteed by

A global observer for attitude and gyro biases from vector measurements
, 2016 We consider the classical problem of estimating the attitude and gyro biases of a rigid body from vector measurements and a triaxial rate gyro. We propose a simple "geometry-free" nonlinear observer with guaranteed uniform global asymptotic convergence ...

Uniform Asymptotic Stability Via Liapunov-Razumikhin Technique [PDF]
Proceedings of the American Mathematical Society, 1995 The Liapunov-Razumikhin technique is applied to obtain the uniform asymptotic stability for linear integrodifferential equations in Hilbert spaces, \[ x ′ ( t ) = A [ x ( t ) + ∫

Advanced Materials Technologies, EarlyView.This work establishes a framework for high‐resolution printed interconnects by coupling e‐jet printing control, multilayer deposition, and sintering optimization. Ink properties and printing speed influence particle stacking, while different sintering atmospheres drive distinct microstructural evolution.

On uniform asymptotic $h$-stability for linear non autonomous systems.
Electronic Journal of Qualitative Theory of Differential EquationsA classical result in the theory of stability of nonautonomous linear systems is that the uniform exponential decay of its corresponding transition matrix is equivalent to the uniform asymptotic stability of the trivial solution.

Permanence for a class of non-autonomous delay differential systems
Electronic Journal of Qualitative Theory of Differential Equations, 2018 We are concerned with a class of $n$-dimensional non-autonomous delay differential equations obtained by adding a non-monotone delayed perturbation to a linear homogeneous cooperative system of delay differential equations.

On the uniform asymptotic stability of functional differential equations of the neutral type [PDF]
Proceedings of the American Mathematical Society, 1971 Consider the functional equations of neutral type (1) ( d / d t ) D ( t , x t ) = f ( t , x t ) (d/dt)D(t,{x_t}) =

Advanced Materials Technologies, EarlyView.ABSTRACT Real‐time insight into local chemistry is critical for reliable part quality in additive manufacturing, especially laser powder bed fusion (PBF‑LB/M), where rapid thermal cycles and localized evaporation can undermine part performance. Optical emission spectroscopy (OES) offers non‑intrusive, in situ plume monitoring, but detection geometry ...
