Discrete Implementations Modify the Intuition of Final Set Adjustment in Barrier Function Based Control

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper establishes an implementation‐aware framework for Barrier Function Adaptation (BFA) and shows that discrete‐time realizations fundamentally alter the logic of final‐set adjustment. In particular, sufficient conditions are derived to preserve the key benefits of BFA (predefined performance, gain adaptation with uncertain perturbation

CLEAR Interference Cancellation in a Wideband Dual‐Channel Receiver for Independent Satellite Multi‐Connectivity Links

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT In this paper, the correlation learning estimation and adaptive reduction (CLEAR) of interference, an adaptive, blind and transparent interference compensation method applied in a wideband dual‐channel receiver, is studied for a pair of independent satellite multi‐connectivity links, using the same carrier frequency and signal bandwidth in use

A CFOA-Based Voltage-Mode Multifunction Biquadratic Filter and a Quadrature Oscillator Using the CFOA-Based Biquadratic Filter

open access: yesApplied Sciences, 2019
This paper proposes a new high-input impedance current feedback operational amplifier (CFOA)- based voltage-mode multifunction biquadratic filter and a voltage-mode quadrature oscillator using the proposed high-input impedance CFOA-based biquadratic ...

Ni–Cr Substitution in TiFe: An Integrated Experimental–Modeling Study of Phase Stability and Hydride Thermodynamics

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 8, August 2026.
Combined experimental and theoretical approaches reveal how Cr and Ni substitution in TiFe‐based alloys tune lattice expansion and hydride thermodynamics. While both elements increase hydride stability, they exert opposite effects on the entropy of hydrogen desorption, providing new insight into thermodynamic design of AB‐type hydrogen storage ...

Adaptive and Robust Control of Diamond Quantum Sensors via Meta‐Learning

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 8, August 2026.
Quantum Meta‐Learning: Meta‐learning frameworks address pulse transferability in NV‐center quantum sensing. By training on diverse tasks that simulate experimental variations, robust surrogate models are created that rapidly adapt to new scenarios without extensive recalibration.

Bulk-source-coupled CMOS quadrature oscillators

open access: yesElectronics Letters, 2009
A quadrature oscillator based on a coupling between the bulk and the source of MOS transistors is proposed. Since the resonator load is not directly involved in the coupling process, the oscillation frequency is very close to the resonant frequency, hence a good phase noise characteristic. The developed theory matches very well to the simulations.

Fourier Expansion‐Based Approach to the Parameter Space of Classical Systems

open access: yesAnnalen der Physik, Volume 538, Issue 7, July 2026.
ABSTRACT We propose a new approach to compute the classical metric tensor (CMT) and the Hannay curvature using Fourier series expansions in action‐angle variables. This approach circumvents the need for complex time‐domain integrals or the construction of generating functions, replacing them with algebraic combinations of Fourier coefficients. We prove
