Current Stress Optimization in Buck-Boost Mode Based on New Extended Phase-Shift Dual Active Full-Bridge Converter

open access: yesShanghai Jiaotong Daxue xuebao
To reduce the current stress of dual active full-bridge converters in the buck-boost mode, a current stress optimization control strategy based on new extended-phase-shift modulation is proposed.

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

open access: yesFEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Robust measurement of the diffuse surface by phase shift profilometry

open access: yes, 2014
As one of the most popular non-contact shape measurement methods, phase shift profilometry has been studied for many decades and has found applications in both the scientific and industrial world.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Optimal control strategy of dual active bridge DC-DC converter with combined dual-phase-shift and traditional-phase-shift controls

open access: yes, 2016
In order to reduce the power losses of the dual active bridge (DAB) DC-DC converter, an optimal control strategy combining dual-phase-shift and traditional-phase-shift controls is proposed.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Photonic Phase Shifter Based on Wavelength Dependence of Brillouin Frequency Shift

open access: yes, 2011
We present a novel radio-frequency (RF) photonic phase shifter based on wavelength dependence of Brillouin frequency shift. A continuous and full phase shift up to 360 degrees at 18 GHz is achieved when the wavelength of the optical carrier is scanned ...

Frequency quantization in first-order digital phase-locked loops with frequency-modulated input [PDF]

open access: yes, 2007
Presented at the International Workshop on Nonlinear Maps and their Applications (NOMA '07), INSA, Toulouse, December 13-14, 2007Frequency granularity in a digital phase-locked loop arises from quantization in the number-controlled oscillator which ...
