NEW METHODS FOR TUNING OF MECHANICAL SYSTEMS DURING OPERATION IN STEADY STATE [PDF]

open access: yesScientific Journal of Silesian University of Technology. Series Transport, 2014
The main purpose of this paper is to inform the technical community about new tuning methods of torsional oscillating mechanical systems (TOMS) during operation in a steady state by means of application of pneumatic flexible shaft couplings.

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

open access: yesFEBS 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.

Supermodes of high-repetition-rate passively mode-locked semiconductor lasers [PDF]

open access: yes, 1996
We present a steady-state analysis of high-repetition-rate passively mode-locked semiconductor lasers. The analysis includes effects of amplitude-to-phase coupling in both gain and absorber sections. A many-mode eigenvalue approach is presented to obtain

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Transient power equalization control strategy of virtual synchronous generator in isolated island microgrid with heterogeneous power supply

open access: yesScientific Reports, 2023
In the parallel supply system of synchronous generator and virtual synchronous generator, the physical structure and control structure of the two kinds of power supply are quite different, and it is difficult to distribute the transient power of the two ...

Quantum entanglement and teleportation in pulsed cavity-optomechanics

open access: yes, 2011
Entangling a mechanical oscillator with an optical mode is an enticing and yet a very challenging goal in cavity optomechanics. Here we consider a pulsed scheme to create Einstein-Podolsky-Rosen-type entanglement between a traveling-wave light pulse and ...
