Energy Saving Through High Frequency Electric Resistance Welding [PDF]
, 1983 High-Frequency electric resistance heating systems have been widely used for many years for both welding and heat treating. In the past the major reason for using High-Frequency heating processes has been because of their very much higher speeds compared

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Failure mechanisms of polyimide and perfluoroalkoxy films under high frequency pulses [PDF]
, 2010 Breakdown behaviors of polyimide and perfluoroalkoxy high temperature films under unipolar and bipolar repetitive pulses are investigated. A bipolar 20kV, 20 kHz and fast dV/dt pulse generator has been designed and built to study the impact of pulse ...

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

The merit of high-frequency data in portfolio allocation [PDF]
, 2011 This paper addresses the open debate about the usefulness of high-frequency (HF) data in large-scale portfolio allocation. Daily covariances are estimated based on HF data of the S&P 500 universe employing a blocked realized kernel estimator.

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.
