A general waveguide circuit theory
Journal of Research of the National Institute of Standards and Technology, 1992 This work generalizes and extends the classical circuit theory of electromagnetic waveguides. Unlike the conventional theory, the present formulation applies to all waveguides composed of linear, isotropic material, even those involving lossy conductors and hybrid mode fields, in a fully rigorous way.

Overview of Hydra: a concurrent language for synchronous digital circuit design [PDF]
, 2006 Hydra is a computer hardware description language that integrates several kinds of software tool (simulation, netlist generation and timing analysis) within a single circuit specification. The design language is inherently concurrent, and it offers black

Network Synchronization Revisited: Time Delays in Mutually Coupled Oscillators
IEEE Access, 2022 Coordinated and efficient operation in large, complex systems requires the synchronization of the rhythms of spatially distributed components. Such systems are the basis for critical infrastructure such as satellite navigation, mobile communications, and

Effective theories for circuits and automata [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2011 Abstracting an effective theory from a complicated process is central to the study of complexity. Even when the underlying mechanisms are understood, or at least measurable, the presence of dissipation and irreversibility in biological, computational, and social systems makes the problem harder.

Distinct patterns of speech disorder in early-onset and late-onset de-novo Parkinson’s disease
npj Parkinson's Disease, 2021 Substantial variability and severity of dysarthric patterns across Parkinson’s disease (PD) patients may reflect distinct phenotypic differences. We aimed to compare patterns of speech disorder in early-onset PD (EOPD) and late-onset PD (LOPD) in drug ...

Short-term effect of dopaminergic medication on speech in early-stage Parkinson’s disease
npj Parkinson's Disease, 2022 The effect of dopaminergic medication on speech has rarely been examined in early-stage Parkinson’s disease (PD) and the respective literature is inconclusive and limited by inappropriate design with lack of PD control group.

Revisiting the memristor concept within basic circuit theory
, 2021 In this paper, we revisit the memristor concept within circuit theory. We start from the definition of the basic circuit elements; then, we introduce the original formulation of the memristor concept and summarize some of the controversies on its nature.

A frequency-domain approach to the analysis of stability and bifurcations in nonlinear systems described by differential-algebraic equations [PDF]
, 2007 A general numerical technique is proposed for the assessment of the stability of periodic solutions and the determination of bifurcations for limit cycles in autonomous nonlinear systems represented by ordinary differential equations in the differential ...

Automated video-based assessment of facial bradykinesia in de-novo Parkinson’s disease
npj Digital Medicine, 2022 Even though hypomimia is a hallmark of Parkinson’s disease (PD), objective and easily interpretable tools to capture the disruption of spontaneous and deliberate facial movements are lacking.
