Multi-Objective Unified Optimal Control Strategy for DAB Converters with Triple-Phase-Shift Control

open access: yesEnergies, 2021
To solve the problems of large current stress, difficult soft-switching of all switches, and slow dynamic response of dual active bridge converters, a multi-objective unified optimal control strategy based on triple-phase-shift control was proposed.

On a correlation between EPR data for SASeD doped with Cr3+ and soft modes

open access: yesCondensed Matter Physics, 2007
PR experimental results obtained for SASeD doped with Cr3+ are reported with special emphasis on those observations which reveal the effect of soft modes i.e. the temperature dependence of the DZZ spin-Hamiltonian parameter and the temperature dependence

Spin waves in the soft layer of exchange-coupled soft/hard bilayers

open access: yesAIP Advances, 2016
The magnetic dynamical properties of the soft layer in exchange-coupled soft/hard bilayers have been investigated numerically using a one-dimensional atomic chain model.

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

"Modes of governance in the EU" [PDF]

open access: yes, 2007
...it is the aim of this chapter to, first, clarify the concept of governance, second, highlight basic modes of governance and their role in the EU and, third, develop an explanatory framework for the emergence of specific modes of governance in the ...

Soft robotic fingers with embedded ionogel sensors and discrete actuation modes for somatosensitive manipulation

open access: yes, 2019
Soft robotic grippers enable gentle, adaptive, and bioinspired manipulation that is simply not possible using traditional rigid robots. However, it has remained challenging to create multi-degree-of-freedom soft actuators with appropriate sensory ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

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 ...

Perimeter Modes of Nanomechanical Resonators Exhibit Quality Factors Exceeding 10^{9} at Room Temperature

open access: yesPhysical Review X, 2022
Systems with low mechanical dissipation are extensively used in precision measurements such as gravitational wave detection, atomic force microscopy, and quantum control of mechanical oscillators via optomechanics and electromechanics.
