Adjoint-based optimization of flapping plates hinged with a trailing-edge flap

Theoretical and Applied Mechanics Letters, 2015
It is important to understand the impact of wing-morphing on aerodynamic performance in the study of flapping-wing flight of birds and insects. We use a flapping plate hinged with a trailing-edge flap as a simplified model for flexible/morphing wings in ...

Epitaxial lift-off for solid-state cavity quantum electrodynamics

, 2015
We present a new approach to incorporate self-assembled quantum dots into a Fabry-P\'{e}rot-like microcavity. Thereby a 3$\lambda$/4 GaAs layer containing quantum dots is epitaxially removed and attached by van der Waals bonding to one of the microcavity

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Reduced-order aerodynamic model of a starting plate with discrete-vortex merging

Frontiers in Physics
This study employs potential flow theory with a discrete-vortex method to model the unsteady aerodynamics of a flat plate, with a particular focus on the coupled dynamics of leading-edge and trailing-edge vortices (LEVs and TEVs).

Fabrication technology for high light-extraction ultraviolet thin-film flip-chip (UV TFFC) LEDs grown on SiC

, 2018
The light output of deep ultraviolet (UV-C) AlGaN light-emitting diodes (LEDs) is limited due to their poor light extraction efficiency (LEE). To improve the LEE of AlGaN LEDs, we developed a fabrication technology to process AlGaN LEDs grown on SiC into

New F-theory lifts II: permutation orientifolds and enhanced singularities [PDF]

Journal of High Energy Physics, 2010
In this paper, a procedure is developed to construct compact F-theory fourfolds corresponding to perturbative IIB O7/O3 models on CICY threefolds with permutation involutions. The method is explained in generality, and then applied to specific examples where the involution permutes two Del Pezzo surfaces.

Bio-inspired vortex lift for enhanced manoeuvrability

, 2022
Inspired by highly manoeuvrable species of birds like the peregrine falcon and the swift, static and dynamic computational fluid dynamics (CFD) simulations were conducted to investigate vortex lift in unsteady flows. The configuration corresponds to a 50◦ sweep delta wing with sharp leading edge at Re= 5.0×104.
