Asymmetric Fano resonances are predicted to occur in the linear electronic conductance across a shallow quantum well in a high magnetic field. The Fano lineshape results from the interference between direct transmission and transmission via a quasi-bound state in the well which is weakly mixed with the continuum by tilting the field. The resonance width increases with tilt angle but general S-m...

This paper proposes a computational approach for generation of reference path for upper-limb exoskeletons considering the scapulohumeral rhythms of the shoulder. The proposed method can be used in upper-limb exoskeletons with 3 Degrees of Freedom (DoF) in shoulder and 1 DoF in elbow, which are capable of supporting shoulder girdle. The developed computational method is based on Central Nervous ...

We prove a general stability theorem of an n-dimensional quadratic-additive type functional equation [Formula: see text]by applying the direct method.

Transcranial direct current stimulation (tDCS), a simple means of brain stimulation, possesses a trifecta of appealing features: it is relatively safe, relatively inexpensive and relatively effective. It is also relatively easy to obtain a device and the do-it-yourself (DIY) community has become galvanised by reports that tDCS can be used as an all-purpose cognitive enhancer. We provide practic...

We shall start by telling tile story of the discovery of the Dirac equation. There is no better way of telling it than in the words of the protagonists themselves and this is the way we shall do it. In this, we are greatly helpe.d by the excellent book "Inward Bound" by Abraham Pals (Pals 1986). Almost all our quotations are taken from this source. Every serious student of physics must read thi...

We introduce a new class of systems holding Parity Time (PT)-symmetry locally whereas being globally Psymmetric. The potential is globally symmetric, U=U(|r|), and fulfills PT-symmetry with respect to periodically distributed points r0: U(|r0+r|)=U*(|r0-r|) being r0∫ 0. We show that such systems hold novel properties arising from the merging of the two different symmetries, leading to a strong ...

This paper presents an investigation of the best suitable package formats for long term digital preservation. The choice of a package format for preservation is crucial for future access, thus a thorough analysis of choice is important. The investigation presented here covers setting up requirements for package formats used for long term preserved digital material, and using these requirements ...
