Fluorescence resonance energy transfer (FRET) efficiency measurements based on acceptor photobleaching of yellow fluorescent protein (YFP) are affected by the fact that bleaching of YFP produces a fluorescent species that is detectable in cyan fluorescent protein (CFP) image channels. The presented quantitative measurement of this conversion makes it possible to correct the obtained FRET signal...

The partition coefficient Kp was measured for a headgroup-labeled phospholipid (12:0,12:0)-N-(7-nitrobenz-2oxa-1,3-diazol-4-yl)-PE (12-NBD-PE), equilibrated between LUV of a series of phosphatidylcholines (PC). Fluorescence resonance energy transfer between the 12-NBD-PE and a headgroup-rhodamine-labeled PE was used to find the equilibrium concentration of the 12-NBD-PE in the different LUV. Re...

Piezoelectric-based shunt dampers are developed in recent years because of simplicity in comparison with other methods. In these methods, a part of converted mechanical energy is stored in the internal el...

We argue that the exciton scenario for the magnetic resonance in the cuprate superconductors yields a small spectral weight of the resonance, in agreement with experiment. We show that the small weight is related to its concentration in a small region of momentum and energy. Despite this, we find that a large fermionic self-energy can indeed be generated by a resonance with such properties, i.e...

I discuss the recent attempts to build an effective chiral Lagrangian incorporating massive resonance states. A useful approximation scheme to organize the resonance Lagrangian is provided by the large-NC limit of QCD. Integrating out the resonance fields, one recovers the usual chiral perturbation theory Lagrangian with explicit values for the low-energy constants, parameterized in terms of re...

Hybrid AC/DC microgrids facilitate the procedure of DC power connection into the conventional AC power system by developing the distributed generations (DGs) technologies. The conversion processes between AC and DC electrical powers are more convenient by hybrid systems. In this paper, an energy management system (EMS) for a hybrid microgrid network is proposed due to the optimal utilization of...

Myosin is thought to generate force by a rotation between the relative orientations of two domains. Direct measurements of distances between the domains could potentially confirm and quantify these conformational changes, but efforts have been hampered by the large distances involved. Here we show that luminescence resonance energy transfer (LRET), which uses a luminescent lanthanide as the ene...

The Perrin-Forster theory of sensitized fluorescence is extended by replacing the Coulomb interaction wth its relativistic counterpart, the Breit interaction. The transition matrix element is evaluated in a multipole expansion. The matrix element i s found to be modulated by the retardation factor eikR and to contain terms whch fall off only as l/R. The relation of these terms to spontaneous ph...
