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 AccessA 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

Verified equivalent-circuit model for slot-waveguide modulators
Optics Express, 2020 We formulate and experimentally validate an equivalent-circuit model based on distributed elements to describe the electric and electro-optic (EO) properties of travelling-wave silicon-organic hybrid (SOH) slot-waveguide modulators. The model allows to reliably predict the small-signal EO frequency response of the modulators exploiting purely ...

Versatile vector tools for efficient protein screening across multiple expression systems
FEBS Open Bio, EarlyView.A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

EQUIVALENT CIRCUIT MODEL OF OCTAGONAL ULTRA WIDEBAND (UWB) ANTENNA [PDF]
Journal of Engineering Science and Technology, 2017 This paper presents an equivalent circuit model of an octagonal UWB antenna. The UWB antenna is first designed in the electromagnetic simulator, after which the circuit model is developed to match its result.

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

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments
FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...
