hot off the press hot off the press C ontrol of exocytotic neurotransmitter release is essential for communication in the nervous system and for preventing synaptic abnormalities. The function of synaptosomal-associated protein of 25 kDa (SNAP-25) as a crucial component of the core machinery required for synaptic ves-icle fusion is well established, but evidence is growing to suggest an additio...

We present experimental results on the snap-off dynamics of a drop with viscosity lh dripping through a fluid of viscosity h. This paper focuses on the Stokes regime where both the inner and outer fluid viscous stresses are balanced by the pressure gradients arising from the interfacial curvature. We track the time dependence of the drop profiles near snap-off and find that successive profiles ...

Newly developed high-speed, synchrotron-based X-ray computed microtomography enabled us to directly image pore-scale displacement events in porous rock in real time. Common approaches to modeling macroscopic fluid behavior are phenomenological, have many shortcomings, and lack consistent links to elementary pore-scale displacement processes, such as Haines jumps and snap-off. Unlike the common ...

The large available Hilbert space and high coherence of cavity resonators make these systems an interesting resource for storing encoded quantum bits. To perform a quantum gate on this encoded information, however, complex nonlinear operations must be applied to the many levels of the oscillator simultaneously. In this work, we introduce the selective number-dependent arbitrary phase (snap) gat...

Mechanical instability is often harnessed in mechanical metamaterials to generate a diverse range of functionalities, and can be triggered by either or field stimulus, such as temperature. Existing field-responsive with snap-through instability, however, need rely on input realize functional reversibility, limitation depriving them the capacity operate solely via applied field. This work demons...

Snap-off is a crucial mechanism for drop breakup in multiphase flow within porous media. However, the systematic investigation of snap-off dynamics constricted capillaries with varying pore and throat heights remains limited. In this study, we conducted three-dimensional simulations behavior square capillary non-uniform depth, employing color-gradient lattice Boltzmann model. Our analysis encom...
