Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Measurements on pointing error and field of view of Cimel-318 Sun photometers in the scope of AERONET [PDF]

Atmospheric Measurement Techniques, 2013
Sensitivity studies indicate that among the diverse error sources of ground-based sky radiometer observations, the pointing error plays an important role in the correct retrieval of aerosol properties.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Multi-class learning for vessel characterisation in intravascular ultrasound

ELCVIA Electronic Letters on Computer Vision and Image Analysis, 2014
In this thesis we tackle the problem of automatic characterization of human coronary vessel in IntravascularUltrasound (IVUS) image modality. The basis for the whole characterization process is machinelearning applied to multi-class problems.

Transitive Statistical Sensor Error Characterization and Calibration [PDF]

IEEE Sensors, 2005., 2006
Calibration is the process of identifying and correcting for the systematic bias component of the error in the sensor measurements. On-line and in-field sensor measurement calibration is particularly crucial since manual calibration is expensive and sometimes infeasible.

Global distributions, time series and error characterization of atmospheric ammonia (NH 3 ) from IASI satellite observations

, 2014
. Ammonia (NH3) emissions in the atmosphere have increased substantially over the past decades, largely because of intensive livestock production and use of fertilizers.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Parametric characterization and error analysis of Hopkinson bar waveforms

Next Materials
The Hopkinson bar technique is an essential method for characterizing material dynamic properties. This study develops a parametric framework for stress waveform characterization, incorporating time-dependent markers (t0 to t3), amplitude-dependent ...
