The excitation energy and the nuclear density at the time of breakup are extracted for the α + Au reaction at beam energies of 1 and 3.6 GeV/nucleon. These quantities are calculated from the average relative velocity of intermediate mass fragments (IMF) at large correlation angles as a function of the multiplicity of IMFs using a statistical model coupled with many-body Coulomb trajectory calcu...

The lattice-Boltzmann method was used for three-dimensional simulation of droplet breakup and coalescence in flow fields representative of those encountered in compounding of immiscible polymer blends. Quantitative confirmation of droplet deformation in simple shear was conducted using this method, and showed very good agreement with theoretical results. Droplet breakup in simple shear was simu...

Romantic relationships alter the selves of the individuals within them. Partners develop shared friends and activities and even overlapping self-concepts. This intertwining of selves may leave individuals' self-concepts vulnerable to change if the relationship ends. The current research examines several different types of self-concept change that could occur after a breakup and their relation t...

Numerical simulations are performed to study the breakup of water cylinders in the flow behind normal shocks. The computational setup is similar to previous experiments (Igra and Takayama, 2001, 2003). We examine the qualitative features of the so-called stripping breakup observed in the numerical results. Two interesting flow features are discussed: the existence of recirculation regions and a...

Aerosol reactors pass through regimes where subsets of the population balance terms are dominant. Initially, mixing, reaction, nucleation and accretional growth dominate. This is generally followed by a regime in which coagulation and coalescence control evolution of the particle population into sintered aggregates. Conventionally, the boundary between regimes where coalescence is or is not imp...

The prediction of droplets diameter and velocity distribution in a spray is so difficult since its process and mechanism is not completely known and depends too many parameters. The early stage of the atomization process (Primary Breakup) is clearly deterministic, whereas the final stage of spray formation (Secondary Breakup) is random and stochastic. In the second region, which deals with the ...

We study a mechanism of pulse propagation failure in excitable media where stable traveling pulse solutions appear via a subcritical pitchfork bifurcation. The bifurcation plays a key role in that mechanism. Small perturbations, externally applied or from internal instabilities, may cause pulse propagation failure ~wave breakup! provided the system is close enough to the bifurcation point. We d...

Two studies investigated whether need fulfillment within relationships moderates the associations of attachment anxiety with relationship commitment and persistence. The authors hypothesized that individuals who experience low attachment anxiety would exhibit declining commitment and increased risk of breakup if their partner failed to meet their core psychological needs, whereas individuals wh...

We consider a diffusive interface surface tension model under compressible flow. The equation of interest is the Cahn-Hilliard or Allen-Cahn equation with advection by a non-divergence free velocity field. These are two reduced models which show important properties of the full-scale surface tension model. We prove that both model problems are well-posed. We are especially interested in the beh...

We propose a mechanism of droplet breakup in a symmetric microfluidic T junction driven by pressure decrement in a narrow gap between the droplet and the channel wall. This mechanism works in a two-dimensional setting where the capillary Rayleigh–Plateau instability of a cylindrical liquid thread, suggested earlier D. Link, S. Anna, D. Weitz, and H. Stone, Phys. Rev. Lett. 92, 054503 2004 as th...
