Pain and the perception of space in fibromyalgia. [PDF]

open access: yesSci Rep
The Economy of action hypothesis postulates that bodily states rescale the perception of the individual’s environment’s spatial layout. The estimation of distances and slopes in navigation space (i.e. the space reachable by locomotion) is influenced by sensations relating to body condition and the metabolic cost of the actions.

Non‐linear optical limiting technology based on backward stimulated Brillouin scattering in grade‐index optical fibres

open access: yesElectronics Letters, 2021
An effective non‐linear optical limiting technology is proposed here based on backward stimulated Brillouin scattering in grade‐index optical fibres. The excellent non‐linear optical limiting performance is experimentally verified by using 0.5 and 1 m ...

The cost of aiming for the best answers: Inconsistent perception

open access: yesFrontiers in Integrative Neuroscience, 2023
The laws of physics and mathematics describe the world we live in as internally consistent. As these rules provide a very effective description, and our interaction with the world is also very effective, it seems self-evident that our perception follows ...

Semi‐supervised classification of fundus images combined with CNN and GCN

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose Diabetic retinopathy (DR) is one of the most serious complications of diabetes, which is a kind of fundus lesion with specific changes. Early diagnosis of DR can effectively reduce the visual damage caused by DR. Due to the variety and different morphology of DR lesions, automatic classification of fundus images in mass screening can ...

COMP Report: CPQR technical quality control guidelines for use of positron emission tomography/computed tomography in radiation treatment planning

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Positron emission tomography with x‐ray computed tomography (PET/CT) is increasingly being utilized for radiation treatment planning (RTP). Accurate delivery of RT therefore depends on quality PET/CT data. This study covers quality control (QC) procedures required for PET/CT for diagnostic imaging and incremental QC required for RTP.
