Disordered spherical bead packs are anisotropic
Investigating how tightly objects pack space is a long-standing problem, with relevance for many disciplines from discrete mathematics to the theory of glasses. Here we report on the fundamental yet so far overlooked geometric property that disordered mono-disperse spherical bead packs have significant local structural anisotropy manifest in the shape of the free space associated with each bead...
متن کاملDynamic percolation and Slow Relaxation in Glass-like Materials
Glass-like materials are nonequilibrium systems where the relaxation time may exceed reasonable time scales of observations. In the present paper a dynamic percolation model is introduced in order to explain the principal properties of glass-like materials near the dynamic transition. Here, contrary to conventional percolation problems, clusters are groups of particles dynamically correlated. I...
متن کاملThe XY spin glass with slow dynamic couplings
We investigate an XY spin-glass model in which both spins and couplings evolve in time: the spins change rapidly according to Glauber-type rules, whereas the couplings evolve slowly with a dynamics involving spin correlations and Gaussian disorder. For large times the model can be solved using replica theory. In contrast to the XY -model with static disordered couplings, solving the present mod...
متن کاملRetention of platelets by glass bead filters.
Whole blood was passed through glass bead filters and the retention of platelets studied under various experimental conditions. Platelet retention was similar over a wide range of blood flow rates; however, it was decreased at fast rates of flow. Platelet retention was not influenced by the haematocrit value of the blood over a wide range. Retention in filters containing siliconized beads was s...
متن کاملGlass Bead Calorimeter and Fiber Optic Readout
Large volume calorimeters are traditionally based on construction from high-density material or a “sandwich” construction of alternating layers of active and passive material. Dense scintillating material, made from materials such as BGO or lead-glass, is too costly to be used on a very large scale. In sandwich technology, energy resolution is often reduced due to a large fraction of the signal...
