Heterodyne Angle Deviation Interferometry in Vibration and Bubble Measurements

open access: yesApplied Sciences, 2016
We proposed heterodyne angle deviation interferometry (HADI) for angle deviation measurements. The phase shift of an angular sensor (which can be a metal film or a surface plasmon resonance (SPR) prism) is proportional to the deviation angle of the test ...

Proposal to observe the strong Van der Waals force in e+\bar{e} -> 2 \pi

open access: yes, 2003
Large discrepancy of the p-wave phase shift data $\delta_{1}(\nu)$ of the $\pi$-$\pi$ scattering from those of the dispersion calculation is pointed out.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS 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+.

Design, fabrication and performance analysis of TTD structures for S-band active phased array RF beamforming networks

open access: yesMANAS: Journal of Engineering, 2019
In this study an eight-channel active analog beamforming structure is designed and developed in subsystems by using a Applied Wave Research (AWR) simulation program. This structure works in S-band and contains true-time-delay (TTD) systems.

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.

Relative phase change during quantum operation

open access: yes, 2003
Quantum operations represented by completely positive maps encompass many of the physical processes and have been very powerful in describing quantum computation and information processing tasks.

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

open access: yesFEBS 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

Power Flow Control using Phase Shift Transformers

open access: yesTikrit Journal of Engineering Sciences, 2010
The present paper examines and tests an alternative method to control and redirect electric power flow through certain paths (transmission lines). The control and redirecting of power flow is achieved through the use of phase shift transformers PSTs.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS 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.

Level Reduction of Output Noise of Reference Voltage Sources

open access: yesActa Technologica Agriculturae, 2018
Technologies for processing of digital signals find broad application in all spheres of the human activity, including agriculture. Further perfecting of these technologies is related to increasing of resolving power in analogue-to-digital and digital-to ...
