The shift and broadening of the vibrational frequency of a diatomic molecule adsorbed on a metal surface are calculated on the basis of electromagnetic interactions. Finite molecular size and nonlocal metal response are included in a calculation of the response function, whose pole is the complex normal mode frequency. Finite molecular size is described by a model of a point-like vibrational mo...

The Coulomb gauge has a long history and many uses. It is especially useful in bound state applications. An important feature of this gauge is that the matter fields have an infra-red finite propagator in an on-shell renormalisation scheme. This is, however, only the case if the renormalisation point is chosen to be the static point on the mass-shell, p = (m, 0, 0, 0). In this letter we show ho...

Chemotaxis proteins organize into large, highly ordered, chemotactic signaling arrays, which in Vibrio species are found at the cell pole. Proper localization of signaling arrays is mediated by ParP, which tethers arrays to a cell pole anchor, ParC. Here we show that ParP's C-terminus integrates into the core-unit of signaling arrays through interactions with MCP-proteins and CheA. Its intercal...

An improved study to the s wave πK elastic scatterings and the kappa resonance Abstract We point out that the dispersion relation for the left hand cut integral presented in one of our previous paper (Nucl. Phys. A733(2004)235) is actually free of subtraction constant, even for unequal mass elastic scatterings. A new fit to the LASS data is performed and we find a κ pole with M κ = 694 ± 53M eV...

To examine the dependence of poleward force at a kinetochore on the number of kinetochore microtubules (kMTs), we altered the normal balance in the number of microtubules at opposing homologous kinetochores in meiosis I grasshopper spermatocytes at metaphase with a focused laser microbeam. Observations were made with light and electron microscopy. Irradiations that partially damaged one homolog...

Differentiation generates oscillations. For the nth derivative f(n, t) of a function f(t) that is analytic in a strip, including the real t-axis, the oscillations occupy a t interval that gets larger as n increases. The oscillations are studied in detail using integral representations and large-n asymptotics. For functions with singularities (poles or branch-points) in the complex t-plane, the ...

Asymptotic normalization coefficients (ANC) determine the overall of cross sections peripheral radiative capture reactions. In present paper, we treat ANC $C$ for virtual decay $^{16}$O$(0^+; 6.05$ MeV)$\to \alpha+^{12}$C(g.s.), known values which are characterized by a large spread $(0.29-1.65)\times 10^3$ fm$^{-1/2}$. The is found analytic continuation in energy $\alpha^{12}$C $s$-wave scatte...

Based on the recently presented conductance cell, hvo specific operational modes are proposed. In the oscillator mode, the conductivity of the electrolyte determines the frequency of an oscillator, experimentally obtaining a shift from 10 to 27 kHz for a KC1 concentration range from 0.5 to 100 mM. In the pole mode, an inductor is placed in series with the cell, giving the real electrolyte resis...

The eeective Lagrangian and power counting rules for non-relativistic gauge theories are derived via a systematic expansion in the large c limit. It is shown that the 1=c expansion leads to an eeective eld theory which incorporates a multi-pole expansion. Within this theory there is no need for heuristic arguments to determine the scalings of operators. After eliminating c from the lowest order...

The pinch technique (PT) is applied to neutral current amplitudes, focusing on the mixing problem. Extending recent arguments due to Papavassiliou and Pilaftsis, it is shown that the use of the PT self-energies does not shift the complex-valued position of the pole through order O(g). This leads (to the same accuracy) to a simple interpretation of MZ , the mass measured at LEP, in terms of the ...
