Ceramide mediates radiation-induced germ cell apoptosis via regulating mitochondria function and MAPK factors in Caenorhabditis elegans

open access: yesEcotoxicology and Environmental Safety, 2021
Studies about radiation damage in vivo are very significant for healthy risk assessment as well as cancer radiotherapy. Ceramide as a second messenger has been found to be related to radiation-induced apoptosis. However, the detailed mechanisms in living

Design of Plasmonic Photonic Crystal Fiber for Highly Sensitive Magnetic Field and Temperature Simultaneous Measurement

open access: yesMicromachines, 2023
A high-sensitivity plasmonic photonic crystal fiber (PCF) sensor is designed and a metal thin film is embedded for achieving surface plasmon resonance (SPR), which can detect the magnetic field and temperature simultaneously.

Magnetic nanoparticle sensing: decoupling the magnetization from the excitation field [PDF]

open access: yesJournal of Physics D: Applied Physics, 2013
Remote sensing of magnetic nanoparticles has exciting applications for magnetic nanoparticle hyperthermia and molecular detection. We introduce, simulate, and experimentally demonstrate an innovation---a sensing coil that is geometrically decoupled from the excitation field---for magnetic nanoparticle spectroscopy that increases the flexibility and ...

Sensing Magnetic Fields with Magnetosensitive Ion Channels [PDF]

open access: yesSensors, 2018
Magnetic nanoparticles are met across many biological species ranging from magnetosensitive bacteria, fishes, bees, bats, rats, birds, to humans. They can be both of biogenetic origin and due to environmental contamination, being either in paramagnetic or ferromagnetic state.

Magnetic Field Sensing for Pedestrian and Robot Indoor Positioning [PDF]

open access: yes2021 International Conference on Indoor Positioning and Indoor Navigation (IPIN), 2021
In this paper we address the problem of indoor localization using magnetic field data in two setups, when data is collected by (i) human-held mobile phone and (ii) by localization robots that perturb magnetic data with their own electromagnetic field. For the first setup, we revise the state of the art approaches and propose a novel extended pipeline ...

Magnetic Fault-Tolerant Attitude Control with Dynamic Sensing for Remote Sensing CubeSats

open access: yesRemote Sensing, 2023
CubeSats have extensive applications in the realm of remote sensing. However, due to size constraints, attitude determination and control systems (ADCS) often adopt an integrated and densely packed structure.

Magneto-optical sensing of magnetic field [PDF]

open access: yesOptics Communications, 2013
Abstract The non-reciprocity of magneto-optical reflection response by surface plasmon excitation in a planar glass/Fe/Au/air system with prism coupling is studied. We aim to find the optimal thicknesses of metallic layers with regard to the reflectance sensitivity to an external magnetic field.
