Shape Derivative of Drag Functional [PDF]

open access: yesSIAM Journal on Control and Optimization, 2010
In this paper, compressible, stationary Navier-Stokes equations are considered. The model is well-posed, and there exist weak solutions in bounded domains, subject to inhomogeneous boundary conditions. The shape sensitivity analysis is performed for Navier-Stokes boundary value problems in the framework of small perturbations of the so-called ...

Microstructure and mechanical properties of in-situ hybrid reinforced (TiB+TiC)/Ti composites prepared by laser powder bed fusion

open access: yesJournal of Materials Research and Technology
To address the problems of insufficient strength and low hardness in pure titanium, a new Ti–B–C powder system was used to prepare in-situ hybrid reinforced (TiB + TiC)/Ti composites by laser powder bed fusion (LPBF) technology.

High strength and ductility in a dual-phase hetero-structured AlCoCrFeNi2.1 eutectic high-entropy alloy by powder metallurgy

open access: yesMaterials Research Letters
We used powder hot extrusion followed by annealing to fabricate a dual-phase AlCoCrFeNi2.1 eutectic high-entropy alloy consisting of both non-recrystallized and recrystallized grains with dense nano-sized precipitates arranged in heterogeneous structures.

Gaussian-preserved, non-volatile shape morphing in three-dimensional microstructures for dual-functional electronic devices

open access: yesNature Communications, 2021
Designing the functional diversification of electronic devices with morphable 3D structures in multistable states remains a challenge. Here, the authors present a Gaussian-preserved shape-morphing system to realize ultrafast shape morphing and non ...

Serum Myonectin Levels Are Positively Associated With Physical Function and Lower Frailty‐Related Limitation in Maintenance Hemodialysis Patients: A Cross‐Sectional Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Maintenance hemodialysis (MHD) patients frequently suffer from frailty, characterized by reduced physical function and poor prognosis. Myokines, such as myonectin, secreted by muscle, are emerging regulators of systemic health. This study investigated the relationship between serum myonectin, adipokines (adiponectin, omentin), and ...

Sensory-motor cortices shape functional connectivity dynamics in the human brain

open access: yesNature Communications, 2021
Spontaneous fluctuations in brain activity exhibit complex spatiotemporal patterns across animal species. Here the authors show that sensory-motor regions and spatial heterogeneity in excitation-inhibition balance might shape multi-stability in brain ...
