Nonlinear Equivalent-Circuit Modeling of a Fast Photodiode [PDF]

IEEE Photonics Technology Letters, 2014
A new nonlinear equivalent circuit model of a photodiode is proposed to describe the conversion of the laser relative intensity noise to microwave phase noise. This conversion is realized through a nonlinear RC circuit. The validity of this model has been confirmed by the good agreement between simulation and experimental results at different microwave

DECiM: Determination of equivalent circuit models

SoftwareX
Electrochemical Impedance Spectroscopy (EIS) is a widely used, nondestructive electrochemical technique for analyzing many different systems. Currently, the most popular analysis method for EIS data is via Equivalent Circuit Models (ECMs). Many programs exist for constructing ECMs and fitting them to data, but these programs are often closed-source. In

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Targeting transcription factors associated with hemoglobinopathies: Lessons from successful interventions and implications for cancer

Molecular Oncology, EarlyView.
This review summarizes the transcription factors, repressive chromatin‐modifying complexes, and epigenetic mechanisms that control fetal hemoglobin repression. Notably, many regulators of γ‐globin silencing also function in transcriptional and epigenetic networks that drive cancer, highlighting opportunities to translate advances in hemoglobinopathy ...
