Sustainable Low‐Field Cardiovascular Magnetic Resonance in Changing Healthcare Systems—An Update

NMR in Biomedicine, Volume 39, Issue 7, July 2026.
Low‐field cardiovascular MRI offers a cost‐effective and accessible alternative to conventional high‐field systems. Recent technological advances have improved image quality, safety, and device compatibility, expanding its clinical applications. These developments position low‐field CMR as a scalable solution to improve global cardiovascular imaging ...

HALBACH ARRAY LAUNCH SYSTEM

Review of the Air Force Academy, 2016
This paper presents a new design of an electromagnetic launch system which solves the weakness of previous designs. The presented system is based on Halbach array arrangements of permanent magnets. In the first part of paper are presented the railgun and coilgun designs and the weakness are identified.

A Passive Shimming Method for Halbach Magnet Based on Numerical Optimization Algorithm

Chinese Journal of Magnetic Resonance
In recent years, Halbach magnet has been extensively used in miniaturized NMR spectrometers. However, the inhomogeneity of the magnetic field of permanent magnets poses a challenge to passive shimming method.

Open‐Source Multinuclear Low‐Field Preclinical MRI Scanner

NMR in Biomedicine, Volume 39, Issue 6, June 2026.
A step‐by‐step guideline for the construction of an open‐source multinuclear low‐field MRI scanner for preclinical studies is presented together with the first images acquired with the device. The scanner can detect 1H, 23Na, hyperpolarized 13C, and 15N signals at 66 mT. ABSTRACT Low‐field MRI (B0 ≤ 0.2 T) is emerging as a technology with the potential

Halbach undulators using right triangular magnets

Physical Review Accelerators and Beams, 2019
Undulators and wigglers based on Halbach arrays have been in widespread use since their description in the 1980s, due to the high fields they generate from permanent magnets.

Electromagnetic Performance Analysis on the Bearingless Permanent Magnet Synchronous Motor With Halbach Magnetized Rotor

IEEE Access, 2019
In order to approximately obtain sinusoidal air-gap magnetic field and get larger radial levitation force of the bearingless permanent magnet synchronous motor (BPMSM), a novel BPMSM with Halbach magnetized rotor is proposed.

Kripke's Reduction of Löb's Theorem to the Second Incompleteness Theorem

Theoria, Volume 92, Issue 3, June 2026.
ABSTRACT In this paper, we discuss Kripke's reduction of Löb's Principle to the Second Incompleteness Theorem. We have a closer look at the non‐constructive character of the reduction. We reflect on what the argument has to tell us. In the Appendix, We give a strengthening of Löb's Principle suggested by Kripke's reduction.

Kripke on Gödel Incompleteness

Theoria, Volume 92, Issue 3, June 2026.
ABSTRACT This paper surveys six of Saul Kripke's highly creative ideas and results on Gödel incompleteness, from when he was an undergraduate to last publications. These include his extension of incompleteness from sentences to predicates, his model‐theoretic proof of incompleteness of arithmetic, his compelling analysis of incompleteness in terms of ...

4D‐Printed Magneto‐Plasmonic Microrobots for Programmable Spatiotemporal De‐Icing

Advanced Functional Materials, Volume 36, Issue 42, 26 May 2026.
A 4D‐printing strategy is introduced to achieve programmable de‐icing devices. By aligning gold–magnetite nanofillers within a photosensitive resin, the printed structures exhibit dual magnetic and plasmonic functionalities, enabling precise spatio‐temporal ice removal through thermoplasmonic effects.
