A Neuransistor with Excitatory and Inhibitory Neuronal Behaviors for Liquid State Machine

Advanced Materials, EarlyView.
The neuransistor integrates hybrid excitatory and inhibitory dynamics, enabling liquid state machine implementation. It operates via charge trapping in a two‐dimensional electron electron gas (2DEG)/TiO2−x structure and features a three‐terminal design for efficient masking functionality. Simulations demonstrate its effectiveness in predicting temporal

A review of recent studies on nonlinear dynamics of microtubules and DNA [PDF]

Proceedings of the 1st CONFERENCE ON NONLINEARITY, Chapter 5, Editors: B. Dragovich, Z. Cupic, Publisher: Serbian Academy of Nonlinear Sciences, Belgrade, 2020, Serbia, ISBN: 978-86-905633-4-0, 2020
Nonlinear dynamics of two biomolecules is studied. These are a microtubule and DNA molecule. Two mathematical procedures are explained, yielding to three kinds of solitary waves moving through the systems. These waves are kinks, modulated solitary waves called breathers and bell-type solitons.

Dynamical structure factor of a nonlinear Klein-Gordon lattice [PDF]

Physical Review B 72 (2005) 184301, 2008
The quantum modes of a nonlinear Klein-Gordon lattice have been computed numerically [L. Proville, Phys. Rev. B 71, 104306 (2005)]. The on-site nonlinearity has been found to lead to phonon bound states. In the present paper, we compute numerically the dynamical structure factor so as to simulate the coherent scattering cross section at low temperature.

Effective synchronization of a class of Chua's chaotic systems using an exponential feedback coupling [PDF]

, 2013
In this work a robust exponential function based controller is designed to synchronize effectively a given class of Chua's chaotic systems. The stability of the drive-response systems framework is proved through the Lyapunov stability theory.

Mechanical Resonant Sensing of Spin Texture Dynamics in a 2D Antiferromagnet

Advanced Materials, EarlyView.
Detection of antiferromagnetic spin texture in a 2D magnetic crystal is achieved through nanomechanical resonators at radio frequencies. Sharp magnetic transitions that lead to abrupt changes in mechanical linear and nonlinear responses are assigned to antiferromagnetic domain motions.

Low‐Noise, Unbiased Ferromagnetic‐Resonance‐Driven Thin‐Film Integrated Giant Magnetoimpedance Sensors

Advanced Materials Technologies, EarlyView.
Utilizing a novel (Ni81Fe19/Ti)4/Cu/(Ni81Fe19/Ti)4 thin‐film multilayer with low coercive field, low damping and a superior GMI ratio, a compact, low‐noise unbiased FMR‐driven integrated GMI sensor with a superior magnetic noise performance of ≈100 pT/√Hz is first demonstrated, owing to reduced phase noise from well‐defined aligned magnetic domains and

Nonlinear focusing in dynamic crack fronts and the micro-branching transition [PDF]

Phys. Rev. Lett. 119, 215505 (2017), 2017
Cracks in brittle materials produce two types of generic surface structures: facets at low velocities and micro-branches at higher ones. Here we observe a transition from faceting to micro-branching in polyacrylamide gels that is characterized by nonlinear dynamic localization of crack fronts.

Testing For Nonlinearity Using Redundancies: Quantitative and Qualitative Aspects

, 1994
A method for testing nonlinearity in time series is described based on information-theoretic functionals -- redundancies, linear and nonlinear forms of which allow either qualitative, or, after incorporating the surrogate data technique, quantitative ...

Nonlinear dynamics of polar regions in paraelectric phase of (Ba1-x,Srx)TiO3 ceramics [PDF]

, 2017
The dynamic dielectric nonlinearity of barium strontium titanate (Ba1-x,Srx)TiO3 ceramics is investigated in their paraelectric phase. With the goal to contribute to the identification of the mechanisms that govern the dielectric nonlinearity in this family, we analyze the amplitude and the phase angles of the first and the third harmonics of ...
