In Situ Electric-Field Study of Surface Effects in Domain Engineered Pb(In_1/2Nb_1/2)O₃-Pb(Mg_1/3Nb_2/3)O₃-PbTiO₃ Relaxor Crystals by Grazing Incidence Diffraction

Crystals, 2020
In this work, we present a grazing incidence X-ray diffraction study of the surface of a 0.24Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 (PIN-PMN-PT) [011] poled rhombohedral single crystal.

Robotic Interventional Needle Insertion Assisted by a Cable‐Driven Parallel Robot

Advanced Intelligent Systems, Volume 8, Issue 1, January 2026.
This article presents a body‐mounted cable‐driven parallel robot assisting the needle insertion procedure designated for automated interventional pain therapy. The 3D‐printed robot body and multiple thin cables can achieve high X‐ray compatibility for intervention. The robot performs full 6‐degree of freedom needle insertion and remote center of motion

Isomorphic Control in Energy Storage Systems Based on Graph‐Based Digital Twins

Digital Twins and Applications, Volume 3, Issue 1, January/December 2026.
This paper proposes a graph‐based framework leveraging Activity‐on‐Edge networks to establish structural isomorphism between virtual models and physical controllers. Validated through a Mixed‐Integer Linear Programming‐based Automatic Generation Control strategy, the architecture effectively bridges the implementation gap, ensuring deterministic real ...

Faecal haemoglobin concentrations are associated with all-cause mortality and cause of death in colorectal cancer screening

BMC Medicine, 2023
Background Colorectal cancer (CRC) screening reduces all-cause and CRC-related mortality. New research demonstrates that the faecal haemoglobin concentration (f-Hb) may indicate the presence of other serious diseases not related to CRC.

A dynamic anthropomorphic phantom for end‐to‐end testing in image‐ and surface‐guided adaptive radiotherapy

Medical Physics, Volume 52, Issue 11, November 2025.
Abstract Background Respiratory and digestive motion can compromise the accuracy of radiotherapy (RT), affecting tumor targeting and healthy tissue sparing. Current phantoms often fail to replicate complex organ movements and lack compatibility with advanced imaging modalities like magnetic resonance imaging (MRI) and 4D computed tomography (4DCT ...

Beckhoff and TwinCAT 3 System Development Guide [PDF]

, 2015
This document is a guide for setting up a Beckhoff hardware controller and a development PC. It is assumed that the development PC runs Windows 7 or Window 8/8.1, although other versions of Windows (including 32-bit and 64-bit) should also work.
