Mixed FEM for Shells of Revolution Based on Flow Theory and its Modifications

Structural Mechanics of Engineering Constructions and Buildings
For describing elastoplastic deformation, three versions of constitutive equations are used. The first version employs the governing equations of the flow theory.

Nanoamphizymes: Self‐Assembled Amphiphilic Enzymatic Nanomaterials for High‐Performance Biocatalysis and Biosensing

Advanced Functional Materials, EarlyView.
An amphiphilic GOx nanoamphizyme was constructed by covalently introducing hydrophobic PPNI linkers onto GOx, enabling spontaneous self‐assembly into tunable nanoparticles. Mild crosslinking further stabilized the assemblies and enhanced catalytic performance and stability.

Demand for Money: A Study in Testing Time Series for Long Memory and Nonlinearity [PDF]

This paper draws attention to the limitations of the standard unit root/cointegration approach to economic and financial modelling, and to some of the alternatives based on the idea of fractional integration, long memory models, and the random field ...

RATIONAL DESIGN OF NONLINEAR-DEFORMABLE STRUCTURALLYHETEROGENEOUS ELEMENTS OF STRUCTURES

International Journal for Computational Civil and Structural Engineering
The article deals with the problem of rational design of a nonlinearly deformable heterogeneous composite Timoshenko rod under force impact. The rod has a structure that is symmetrical relative to the force plane, formed by the connection of quasi ...

Multidimensional‐Encoded High‐Fidelity Spectrometers With a Floating‐Base Bipolar Junction

Advanced Functional Materials, EarlyView.
A floating‐base bipolar junction photodetector enables multidimensional spectral encoding through synergistic gate‐ and drain‐bias modulation of interfacial barrier matching. The resulting complementary spectral responses form a diverse, weakly correlated response matrix, enabling robust and high‐fidelity spectral reconstruction even at sub‐nanoampere ...

Examples of Physical Systems Described by the Duffing Equation

, 2011
In this chapter several examples of physical systems whose dynamic behaviour can be approximated by several forms of the Duffing equation are given. The physical systems are chosen to illustrate the physical phenomena that result in different forms of ...

Neuromorphic Devices for Extreme Environments: State‐Variable Reliability and Stabilization Strategies

Advanced Functional Materials, EarlyView.
Neuromorphic devices for extreme environments are interpreted through the physical states that store and process information. Radiation, temperature extremes, and vacuum can perturb vacancies, filaments, trapped charges, polarization, interfaces, and readout signals.

Modulational instability in two-component discrete media with cubic-quintic nonlinearity

, 2009
The effect of cubic-quintic nonlinearity and associated intercomponent couplings on the modulational instability MI of plane-wave solutions of the two-component discrete nonlinear Schrödinger DNLS equation is considered.

Emergence of a Hexagonal Fe2S2 Single Layer Without a Bulk Counterpart via Phase Transformation

Advanced Functional Materials, EarlyView.
Upon annealing, single‐layer Mackinawite iron sulfide transforms into a previously unknown hexagonal Fe2S2${\rm Fe}_2{\rm S}_2$ phase with β$\beta$‐CuI structure. STM, LEED, and first‐principles calculations identify the structure and show that electronic correlations and magnetic order are important for its stability.

Pathways to randomness in the economy: Emergent nonlinearity and chaos in economics and finance [PDF]

This paper: (1) Gives a general argument why research on nonlinear science in general and chaos in particular is important in economics and finance. (2) Puts forth two definitions of stochastic nonlinearity (IID-Linearity and MDS-Linearity) for nonlinear
