A new theory of ligand-receptor bonds in biological cells that accounts for membrane fluctuations reveals an orders-of-magnitude increase binding rates and the range over which a receptor can recognize its ligand.

in this work a new resistance model has been presented based on that of henis-tripodi which can be used for interpretation of gas permeation data in composite and asymmetric membranes. in contrast to the previous works, in this model the fraction of the support layer surface that includes the pores filled with coating material has been taken into account. the influences of the filled pores on s...

M(atrix) theory on an orbifold and classical two-branes therein are studied with particular emphasis to heterotic M(atrix) theory on S1=Z2 relevant to strongly coupled heterotic and dual Type IA string theories. By analyzing orbifold condition on Chan-Paton factors, we show that three choice of gauge group are possible for heterotic M(atrix) theory: SO(2N), SO(2N + 1) or USp(2N). By examining a...

This letter is an attempt to carry out a first-principle computation in M-theory using the point of view that the eleven-dimensional membrane gives the fundamental degrees of freedom of M-theory. Our aim is to derive the exact BPS R couplings in M-theory compactified on a torus T from the toroidal BPS membrane, by pursuing the analogy with the one-loop string theory computation. We exhibit an S...

We give some evidence that the worldvolume theory of the M-theory KK 6-brane is governed by a non-critical membrane theory. We use this theory to give a matrix description of Mtheory on T .

In part I of this work, we presented a theory for adhesionless contact of a pressurized neo-Hookean plane-strain membrane to a rigid substrate. Here, we extend our theory to include adhesion using a fracture mechanics approach. This theory is used to study contact hysteresis commonly observed in experiments. Detailed analysis is carried out to highlight the differences between frictionless and ...
