Force characterization and coordinate transformation of a fixed-bias flux three-phase magnetic bearing [PDF]

open access: yesAIP Advances
Conventional hybrid magnetic bearings employ permanent magnets (PMs) for bias flux together with actively controlled electromagnets; however, the control forces are typically obtained by modulating excitation currents on top of the bias field.

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

open access: yesFEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

Bearing Currents in Permanent Magnet Synchronous Machines

open access: yes, 2011
Diplomityössä on esitelty ja tutkittu laakerivirtailmiötä sähkökoneissa. Työn pääpaino on suurissa kestomagneettitahtikoneissa, joissa niin sanotut kiertävät laakerivirrat ovat dominoivia.

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

open access: yesFEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Influence of system parameters in variable speed AC-induction motor drives on parasitic electric bearing currents

open access: yes, 2020
High frequency bearing currents are a parasitic phenomenon that affects inverter-fed induction machines, causing damage and wear to the mechanical bearings, which might lead to unexpected failures, increase of the machine downtime and reduction of its ...

Effects of IGFBP4 deficiency on human preadipocyte proliferation and differentiation through the IGF1R/AKT pathway

open access: yesFEBS Open Bio, EarlyView.
IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.
