We report a light microscopy study of interactions between colloidal particles either chemically bound or physisorbed onto flexible giant vesicle fluid membranes. The particles induce pinched shape deformations of the membrane and are driven to negative curvature regions on nonspherical vesicles. The membrane distortions were found to induce interparticle attraction with a range approximately e...

Drawing of the PDMS-based microfluidic chip. Two inlets including one for the oil and one for the in vitro transcription and translation mix (IVTT). Droplets are generated using PDMS based microfluidic chips, the IVTT mixture is pinched off at regular intervals by oil generating monodisperse water in oil emulsions. The droplets are stored in the storage chamber and can be monitored over time wi...

Given n ∈ Z and ε > 0, we prove that there exists δ = δ(ε, n) > 0 such that the following holds: If (M, g) is a compact Kähler n-manifold whose sectional curvatures K satisfy

The possibility of in-memory computing with volatile memristive devices, namely, memristors requiring a power source to sustain their memory, is demonstrated theoretically. We have adopted a hysteretic graphene-based field emission structure as a prototype of a volatile memristor, which is characterized by a non-pinched hysteresis loop. A memristive model of the structure is developed and used ...

Our research is aimed at gaining a better understanding of the electronic properties of organisms in order to engineer novel bioelectronic systems and computing architectures based on biology. This specific paper focuses on harnessing the unicellular slime mold Physarum polycephalum to develop bio-memristors (or biological memristors) and bio-computing devices. The memristor is a resistor that ...

Abstract We investigate the internal 3D magnetic structure of dense interstellar filaments within NGC 1333 using polarization data at 850 μ m from B -fields In STar-forming Region Observations survey James Clerk Maxwell Telescope. Theoretical models predict that field lines in a filament will tend to be dragged radially inward (i.e., pinched) toward central axis due filament’s self-gravity. stu...

We report direct high resolution observation of nonlinear steepened plasma waves excited in the wake of an intense, self-pinched electron beam. Oscillations in both accelerating and deflecting fields are measured, and analyzed in the context of linear and nonlinear plasma wave theory. The degree of nonlinearity in the wakr-fields is shown to be consistent with analytical predictions of the beam...
