A low-viscosity drop breaking apart inside a viscous fluid is encountered when air bubbles, entrained in thick syrup or honey, rise and break apart. Experiments, simulations, and theory show that the breakup under conditions in which the interior viscosity can be neglected produces an exceptional form of singularity. In contrast to previous studies of drop breakup, universality is violated so t...

The electron beam which IS accelerated in the SLAC two-mile accelerator exhibits both transverse and longitudinal interactions with the disk-loaded waveguide, The transverse interactions include such effects as rf steering caused by field asymmetries which exist in the couplers, and beam breakup, The latter is a growing instability which occurs above a given current threshold and deflects the b...

The purpose of this study was to refine and elaborate models of personality and relationship-specific characteristics in the perpetration of stalking and psychological abuse. Three hundred and forty-two college students who had been in intimate relationships completed a series of questionnaires about their most recent breakup and their former relationship. Our hypotheses were supported, with ha...

The cross sections for the (8B,7Be-p) breakup reaction on 58Ni and 208Pb targets at the beam energies of 25.8 MeV and 415 MeV have been calculated within a one-step prior-form distorted-wave Born approximation. The relative contributions of Coulomb and nuclear breakup of dipole and quadrupole multipolarities as well as their interference have been determined. The nuclear breakup contributions a...

Using two different geometries, rectangular obstacles and asymmetric loops, we investigate the breakup dynamics of deformable objects, such as drops and bubbles, confined in microfluidic devices. We thoroughly study two distinct flow configurations that depend on whether object-to-object hydrodynamic interactions are allowed. When such interactions are introduced, we find that the volumes of th...

The reactions induced by the weakly bound Li projectile interacting with the intermediate mass target Co were investigated. Light charged particles singles and α-d coincidence measurements were performed at the near barrier energies Elab = 17.4, 21.5, 25.5 and 29.6 MeV. The main contributions of the different competing mechanisms are discussed. A statistical model analysis, ContinuumDiscretized...

Melting of the mantle during continental breakup leads to magmatic intrusion and volcanism, yet our understanding of the location and dominant mechanisms of melt generation in rifting environments is impeded by a paucity of direct observations of mantle melting. It is unclear when during the rifting process the segmented nature of magma supply typical of seafloor spreading initiates. Here, we u...

A spherical drop is suspended in another liquid and sheared between parallel walls. Numerical simulations for drop deformation under simple shear typically begin with the drop placed in an established flow. For Stokes flow, the drop evolves in a monotone manner to a stationary state or to breakup. Experimental and numerical studies of this result in a critical curve which delineates the capilla...

– The spiral-wave breakup to turbulence in an excitable medium, starting from the spiral-wave center via Doppler instability, is controlled by modulating a local region around the spiral-wave center. The modulation signal is extracted from the controlled region with a certain time delay. By injecting a feedback signal with very low intensity into a very small space area, we can successfully sta...
