Magnetic Misalignment of Interstellar Dust Filaments
The Astrophysical Journal, 2023 We present evidence for scale-independent misalignment of interstellar dust filaments and magnetic fields. We estimate the misalignment by comparing millimeter-wave dust-polarization measurements from Planck with filamentary structures identified in ...

Inductively powered wireless pacing via a miniature pacemaker and remote stimulation control system
Scientific Reports, 2017 Pacemakers have existed for decades as a means to restore cardiac electrical rhythms. However, lead-related complications have remained a clinical challenge. While market-released leadless devices have addressed some of the issues, their pacer-integrated

High-resolution light field prints by nanoscale 3D printing
Nature Communications, 2021 Light field prints displaying 3D information often appear pixelated due to limited resolution and misalignment between lenses and colour pixels. Here, the authors present a one-step process via two-photon polymerization lithography to fabricate light ...

2020 International Conference on Electrical Machines (ICEM), 2020 with the continuous increase in wind turbine generator size the monitoring and diagnosis of drive train shaft misalignment is of growing importance, as this condition contributes to as much as 30% of turbine's downtime. Machine current signature analysis has been widely investigated in conventional machinery as a non-invasive diagnostic tool for shaft ...

Misalignment-Induced Micro-Elastohydrodynamic Lubrication in Rotary Lip Seals
Lubricants, 2020 In literature the lubrication of rotary lip seals is explained by hydrodynamic action on a microscopic scale. This theory assumes perfect concentricity between the seal and the shaft which in reality seldomly occurs.
