Vector blood velocity estimation in medical ultrasound

, 2006
Two methods for making vector velocity estimation in medical ultrasound are presented. All of the techniques can find both the axial and transverse velocity in the image and can be used for displaying both the correct velocity magnitude and direction ...

Utilizing the Metastability of Spidroins as a Strategy for Improving Mechanical Properties of Biomimetic Spider Silk Fibers

Advanced Functional Materials, EarlyView.
Phase transitions are central for the assembly of recombinant silk proteins into fibers. Soluble protein can transition into condensed states such as condensates and gels. These states are metastable and evolve in a time‐dependent way. Metastability depends on the protein sequence, and this relationship can be used to enhance the mechanical properties ...

The influence of the reference zero-velocity on the model of the vector velocity field in a symmetric sunspot

, 1999
It appears that the occurrence of the vector velocity in an umbra caused by the shift of the Doppler-velocity zero-reference level can be successfully corrected by the position change of the point of symmetry of the spot. In such a case, the character of

Pressure Measurement System for Calibration of Multi-hole Probes

Revista Elektrón
Velocity measurement is a central point in all experimental work in Fluid Mechanics, especially if one wants to analyze the wake behind objects inside a wind tunnel. One type of instrument available is the multi-hole probe that infers the velocity vector

Subsequent image pairs are recorded to obtain a velocity field. After applying several processing steps, a two-dimensional velocity vector field yielding two velocity components is obtained.

, 2014
One measurement area is shown (embryo 3, second measurement series; T2), displaying the time-averaged velocity magnitude, . A selection is enlarged to show the corresponding time-averaged velocity vector field, illustrating the spatial resolution of the ...

Remote Activation of Wnt Signaling and Cell Proliferation by E‐Cadherin Magnetomechanical Stimulation

Advanced Functional Materials, EarlyView.
A pioneering magnetogenetic toolkit enables non‐invasive, precise spatiotemporal modulation of intracellular Wnt/β‐catenin signaling. Functionalized magnetic nanoparticles (MNPs@E/EC15) target cellular E‐cadherins to generate localized magnetomechanical forces under low‐intensity magnetic fields.

Bistable Isochoric Chiral Metamaterials with Reprogrammable Multiaxial Responses

Advanced Functional Materials, EarlyView.
An isochoric bistable rotational unit cell enables in situ modification of internal contact conditions post‐fabrication, without altering the global envelope dimensions of the surrounding architecture. By selectively switching between open and closed states, the tessellated chiral metamaterial can reprogram its volumetric response, including bulk ...
