Active reactance in electro‐thermal memristors emerges intrinsically from rapid thermal switching of device resistance, linking current‐controlled and voltage‐controlled negative differential resistance to neuronal spiking dynamics. Opposing temperature coefficients of resistance give rise to active inductive or capacitive responses, enabling tunable ...

Impedance Spectroscopy of Bifurcation Oscillations in S‐Type Self‐Oscillatory Devices
Impedance spectroscopy (IS) reveals stability regimes and bifurcation dynamics in S‐type self‐oscillatory devices. By linking nonlinear control theory with frequency‐domain measurements, experimental signatures of oscillations, entrainment, and phase locking are directly identified.

Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

The Analysis of an Economic Growth Model with Tax Evasion and Delay [PDF]
In this paper we formulate an economic model with tax evasion, corruption and taxes. In the first part the static model is considered, where there are a representative agent and a public institution.

I. Asymptotic Boundary Conditions for Ordinary Differential Equations. II. Numerical Hopf Bifurcation [PDF]
Part I. "Asymptotic Boundary Conditions for Ordinary Differential Equations" The numerical solution of two point boundary value problems on semi-infinite intervals is often obtained by truncating the interval at some finite point.

Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Continuous dependence of boundary values for semiinfinite interval ordinary differential equations
Certain elliptic equations arising in catalysis theory can be transformed into ordinary differential equations on the interval (0,∞). The solutions to these problems usually depend on parameters ρ∈ℝn, say u(t,ρ).

Bifurcation of critical points for continuous families of C^2 functionals of Fredholm type [PDF]
Given a continuous family of C^2 functionals of Fredholm type, we show that the non-vanishing of the spectral flow for the family of Hessians along a known (trivial) branch of critical points not only entails bifurcation of nontrivial critical points but

Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.
