In the last few years spectacular results have been achieved with the demonstration of non vanishing neutrino masses and flavour mixing. Here, a novel method to create a monochromatic neutrino beam, an old dream for neutrino physics, is described based on the recent discovery of nuclei with fast decay through electron-capture to Gamow-Teller resonances in super allowed transitions. Such nuclei ...

In this paper we will compute the effect of the JamesHopf map after applying the Bousfield-Kuhn functor on Morava E-theory, and then compute the monochromatic Hopf invariant of the β family using this cohomological information.

A d-dimensional grid is a set of the form L 1⁄4 1⁄2a1 × · · · ×1⁄2ad , where 1⁄2t 1⁄4 f1; : : : ; tg and aj is a positive integer for j ∈ 1⁄2d . A d-dimensional box is a set of the form fx1; y1g× · · · ×fxd; ydg for some integers xj, yj with j ∈ 1⁄2d , where xj ≠ yj for each j. We give conditions on the set of d-tuples ða1; : : : ; adÞ so that, for every coloring f : L → 1⁄2c , the grid L 1⁄4 1...

We prove that for every fixed k and ` ≥ 5 and for sufficiently large n, every edge coloring of the hypercube Qn with k colors contains a monochromatic cycle of length 2`. This answers an open question of Chung. Our techniques provide also a characterization of all subgraphs H of the hypercube which are Ramsey, i.e., have the property that for every k, any k-edge coloring of a sufficiently large...

Given a coloring of the edges of the complete graph on n vertices in k colors, by considering the neighbors of an arbitrary vertex it follows that there is a monochromatic diameter two subgraph on at least 1 + (n− 1)/k vertices. We show that for k ≥ 3 this is asymptotically best possible, and that for k = 2 there is always a monochromatic diameter two subgraph on at least ⌈ 3 4 n⌉ vertices, whi...

The studies in the VUV and soft-x-ray surface photophysics and photochemistry in the microscopic level using monochromatic synchrotron radiation is a new research category. In this article we employed the techniques of photon-stimulated desorption (PSD) of positive/negative ions and photoelectron spectroscopy (PES) to study the photolysis of molecules adsorbed on single crystal surface by monoc...

In this document I consider the performance of a long pulse spallation source for those neutron scattering experiments that are usually performed with a monochromatic beam at a continuous wave (CW) source such as a nuclear reactor [ 11. This class of expeijments can be represented generically by the upper part of Figure 1. A monochromatic neutron beam with wavevector ki falls on a sample and th...

[1] In this paper we study the energy dissipation due to current-limited wave breaking in monochromatic and random waves with the help of experimental tests. The opposing currents are strong enough for wave blocking to occur. A modified bore model is used to simulate the dissipation rate in the monochromatic waves, and an empirical bulk dissipation formula for wave breaking in random waves is p...

In this note, we improve upon some recent results concerning the existence of large monochromatic, highly connected subgraphs in a 2-coloring of a complete graph. In particular, we show that if n ≥ 6.5(k − 1), then in any 2-coloring of the edges of Kn, there exists a monochromatic k-connected subgraph of order at least n−2(k−1). Our result improves upon several recent results by a variety of au...

This paper (1) reviews the fundamental limits to visual performance imposed by optical imaging and photoreceptor sampling to determine the limits to the potential gains offered by ideal corrections; (2) examines the predicted losses in vision induced by chromatic aberration, phase shifts, typical ocular aberrations, and the gains possible by correcting the monochromatic aberrations of the eye; ...
