Here we use time-lapse microscopy to analyse cell–matrix adhesions in cells expressing one of two different cytoskeletal proteins, paxillin or tensin, tagged with green fluorescent protein (GFP). Use of GFP–paxillin to analyse focal contacts and GFP–tensin to study fibrillar adhesions reveals that both types of major adhesion are highly dynamic. Small focal… (More)

It is proposed that superoscillations play an important role in the interferences that give rise to superluminal effects. To exemplify that, we consider a toy model that a wave packet to travel in zero time and negligible distortion, a distance arbitrarily larger than the width of the wave packet. The peak is shown to result from a superoscillatory… (More)

Cadherins are a family of transmembrane glycoproteins mediating calcium-dependent, homophilic cell-cell adhesion. In addition, these molecules are involved in signaling events, regulating such processes as cell motility, proliferation, and apoptosis. Members of the cadherin subfamily, called either classical or type I cadherins, contain a highly conserved… (More)

The early 1980s brought a new focus to cell adhesion research. This field, which was dominated by structural characterization of different adhesion sites, their subcellular distribution and cytoskeletal association, became increasingly molecular. The adhesion receptors mediating the different forms of cell–matrix and cell–cell adhesion in a wide variety of… (More)

Heat flow between a large thermal 'bath' and a smaller system brings them progressively closer to thermal equilibrium while increasing their entropy. Fluctuations involving a small fraction of a statistical ensemble of systems interacting with the bath result in deviations from this trend. In this respect, quantum and classical thermodynamics are in… (More)

We consider the tunnelling particle as a preand post-selected system and prove that the tunnelling time is the expectation value of the position of a ‘clock’ degree of freedom weakly coupled to it. Such a value, called a ‘weak value’, typically falls outside the eigenvalue spectrum of the operator. The appearance of unusual weak values has been associated… (More)

We show that in the framework of one-dimensional Bohmian Quantum Mechanics[1], for a particle subject to a potential undergoing a weak adiabatic change, the time averages of the particle’s positions typically differ markedly from the ensemble averages. We Apply this result to the case where the weak perturbing potential is the backaction of a measuring… (More)

It is shown that Bell’s counterfactuals admit joint quasiprobability distributions (i.e. joint distributions exist, but may not be nonnegative). A necessary and sufficient condition for the existence among them of a true probability distribution (i.e. non-negative) is Bell’s inequalities. This, in turn, is a necessary condition for the existence of local… (More)

In order to reduce errors, error correction codes need to be implemented fast. They can correct the errors corresponding to the first few orders in the Taylor expansion of the time evolution operator corresponding to the Hamiltonian of the interaction with the environment. If implemented fast enough, the zeroth order error predominates and the dominant… (More)
