In the originally published version of the Article, an incorrect reference number was cited. The final sentence of the first paragraph of the Introduction section should read: ‘The likely reasons are technical difficulties in generating atomic size electron vortex beams, together with fine control of their resulting orbital angular momentum in the case of electron vortex beams, and a low EMCD s...

We report the creation of white-light, achromatic Bessel beams using a spatial light modulator and a prism to compensate for the dispersion. Unlike the Bessel beam created by a refractive axicon, this achromatic beam has a radial wavevector and hence an intensity cross-section which is independent of wavelength. The technique also lends itself to the generation of higher order Bessel beams with...

In this paper I discuss the prospects to observe a CP-odd phase in the leptonic sector, using the intense, pure two-flavour neutrino beams produced in a future neutrino facility, the so-called neutrino factory. The organization is as follows. Section 2 summarizes the state-of-the-art concerning neutrino oscillations. Section 3 describes the neutrino factory. The prospects to measure a CP-odd ph...

There has been a recent development and explosion of interest among academicians across a wide range of disciplines in the use of virtual Class room. Utilization of the virtual class room as a laboratory experimentation for teaching and learning has increased significantly in recent years as development tools for web based applications have become easier to use and computers have become more ca...

The present paper aims to develop an Artificial Neural Network (ANN) formula predict the lateral-torsional buckling (LTB) resistance of slender steel cellular beams. A finite element model is developed and validated through experimental tests followed by a parametric study. 768 models are employed train ANN formula. results compared with analytical as well equation predicted ANN. It was conclud...

The longitudinal stresses in beams subjected to bending also set up transverse stresses within them; they compress the cross section when the beam's curvature is being increased and stretch it when its curvature is being reduced. Analysis shows that transverse stresses rise to a maximum at the neutral axis and increase with both the bending moment applied and the curvature of the beam. These st...
