Phase control of a longitudinal momentum entangled photon state by a deformable membrane mirror
, 2009 We propose a paradigmatic demonstration of the potentialities of a deformable mirror for closed-loop control of a two-photon momentum-entangled state, subject to phase fluctuations.

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.

New technique for digital phase-shift control
Electronics Letters, 1969 A scheme for digital phase-shift control of a locked oscillator is proposed. If the required operating frequency is f and the locking frequency is nf, a reversal in phase of the locking frequency will shift the phase of the locked oscillator by π/n, under suitable conditions.

A Control Allocation System for Automatic Detection and Compensation of Phase Shift Due to Actuator Rate Limiting [PDF]
, 2011 This paper proposes a control allocation system that can detect and compensate the phase shift between the desired and the actual total control effort due to rate limiting of the actuators.

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+.

Energies, 2018 The manipulation of the bidirectional power in a dual-active-bridge converter relies on the adjustment of several phase-shift angles. Improper implementation of those adjustments during the transient process of a step load change may induce transient DC ...

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

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Controlled wide-range quadrature phase-shift network
Electronics Letters, 1969 A system is described which produces a 90° phase shift for a wide range of single-frequency input signals. Thus, whilst it will not handle wideband input signals, it may be useful for such applications as N-path and quadrature modulation filters where the provision of variable-frequency quadrature carrier signals allows the position of the passband to ...
