Estimation of Fano factor for oversquare HPGe detector

open access: yesRadiation Protection and Environment, 2022
Fano factor is a quantity used to measure the departure of the observed variance in the number of charge carriers produced from that predicted using poison statistics. Fano factor varies with the detector type.

Towards possible application of quantum magnetometers in nuclear magnetic logging tools

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2018
One of the key problems of nuclear magnetic logging (NML) is the low sensitivity. As long ago as 1991, it was proposed to use superconducting quantum interferometers (SQUID) to increase the signal-to-noise ratio in the NMR logging devices.

A Pollen‐Enhanced Bionic Mechanoreceptor Induced by Asymmetric Ionic Convection in Hydrogel for Sensory‐Augmented Prostheses

open access: yesAdvanced Science, EarlyView.
This work proposed a pollen‐enhanced bionic mechanoreceptor based on ionic convection. Leveraging the ion anchoring effect of the pollen particle, the output performance could be ∼12 times higher than the original state. By employing deep learning models as AI brains, the feasibility of a sensory‐augmented prosthesis consisting of a pollen‐enhanced ...
