Down With Noise: An Introduction to a Low-Noise Amplifier Survey
IEEE Solid-State Circuits Magazine, 2020 Numerous different circuits are created around the world on a daily basis, making it rather difficult for circuit designers to stay abreast of the latest developments. In an attempt to keep up with these new developments, researchers have compiled a number of spreadsheets that capture key designs and their features.

Molecular Oncology, EarlyView.Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.
