Equivalent circuit model of multiport overlay capacitors

Electronics Letters, 1995
The planar approach is used to derive a lumped-element equivalent circuit model of multiport MIM capacitors. The values of the equivalent circuit elements are given as closed-form expressions. Validation of the model is performed comparing its results with experimental data measured up to 40 GHz.

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death

FEBS Open Bio, EarlyView.
Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

Multi-Purpose Graphene-Based Terahertz Metamaterial and Its Equivalent Circuit Model

IEEE Access
A tunable 2-bit encoder, switch, and absorber using a graphene-based terahertz (THz) metamaterial were developed to operate within 1-4 THz range. The metamaterial comprises three resonators in each unit cell: one split ring resonator containing four gaps

A Wideband Equivalent Circuit for Stripline-Fed Cavity-Backed Slot Radiating Elements

IEEE Access, 2019
An equivalent circuit for stripline-fed cavity-backed slot radiating elements is proposed. The proposed equivalent circuit consist of a transmission line model for the slot mode, a slot end-effect which includes the radiation, and a strip-slot transition

Prognostic Implications of Sleep Architecture for Patients Admitted to the Intensive Care Unit With Status Epilepticus

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Status epilepticus (SE) is associated with significant mortality. Sleep architecture may reflect normal brain function. Impaired sleep architecture is associated with poorer outcomes in numerous conditions. Here we investigate the association of sleep architecture in continuous EEG (cEEG) with survival in SE.

Instantaneous model of a MESFET for use in linear and nonlinear circuit simulations [PDF]

, 1992
A formal approach for nonlinear modeling of FETs is presented. The intrinsic transistor is described by current and charge generators, that are instantaneously dependent on the two internal voltages.
