Abstract:

This work proposed a multiplexer-based neural network (MUXnet), a multiplexer-based, multiplier-free neural network (NN) structure applicable to the implementation of all inner product-based NN layers. An on-chip MUXnet-based neural signal processing unit (NSPU) was designed, achieving a state-of-the-art accuracy of 82.4% on a public human sleep staging dataset, with the lowest …

Single-X-Ray Sensitive Energy-Binning Dosimeter for Closed-Loop Cancer External-Beam Radiotherapy

Single-X-Ray Sensitive Energy-Binning Dosimeter for Closed-Loop Cancer External-Beam Radiotherapy 150 150
Author(s): Rahul Lall, Kyoungtae Lee, Adam Cunha, Rebecca Abergel, Youngho Seo, Ali M. Niknejad, Mekhail Anwar

Abstract:

X-ray radiation dose delivered during cancer external-beam radiotherapy (EBRT) is nonlinear with the biological effect imparted to cancer cells and neighboring healthy tissues. This oftentimes leads to insufficient damage to cancer cells and excessive damage to the surrounding healthy tissues, both increasing toxicity and the risk of cancer recurrence later …
