Background: Stroke is one of the major causes of disability. Therefore, it is important to introduce and develop new treatment approaches in order to improve and enhance post stroke recovery process for medical, social and economical purposes. Aim: To determine the effect of mirror therapy on motor ability of patients with stroke. Methods: This Randomized Controlled Trial was conducted on 38 pa...

Objectives: Hand function is critical for daily life and work, especially with the use of electronic devices. This study determined the effect of mirror therapy in individuals with asymmetrical hand function. Method: Forty-two men with asymmetrical hand function were recruited. All participants were randomly divided into two groups: sham control (n = 21) and mirror therapy (n = 21). Both group...

Abstract: This paper describes a shearing interferometer with four diffraction gratings for dividing light waves. It allows us to use an extended white light source. This feature of the interferometer is discussed and demonstrated by experiments. By constructing the interferometer for testing transparent object, phase distribution of the light wave passing through an optical lens is measured wi...

In the title compound, [ZnCl(2)(C(12)H(12)N(2))], the complete mol-ecule is generated by crystallographic mirror symmetry, with the Zn atom and both chloride ions lying on the reflecting plane, yielding a distorted ZnN(2)Cl(2) tetra-hedral coordination for the metal ion. In the crystal, there are π-π contacts between the pyridine rings [centroid-centroid distance = 3.7857 (17) Å].

We present a design for an optical data communications receiver-transmitter pair based on the holographic correction of a large diameter, poor-quality, reflecting primary mirror. The telescope has a narrow bandwidth (<0.1 nm) with good signal frequency isolation (>60 dB) and is scalable to meter-class apertures. We demonstrate the correction of a reflector telescope with over 2000 waves of aber...

A new method of interference spectroscopy is described. The spectral element is detected photoelectrically by taking the interference between the reflected and the diffracted beams by a modified Michelson interferometer without any computation. The spectrum is scanned by the rotation of the diffraction grating of the interferometer. Modulation of the spectral signal is carried out by the vibrat...

Introduction Recent studies have shown that Fibre Bragg Gratings are well suited to studying the mechanical behaviour of composites [1]. A Fibre Bragg Grating is a small segment of optical fibre with a core of germanium doped silica which gives a periodic and permanent perturbation of the refractive index. An FBG acts like a selective wavelength mirror, reflecting a particular wavelength (Fig. ...

There is much interest in the claim that dysfunction of the mirror neuron system in individuals with autism spectrum condition causes difficulties in social interaction and communication. This paper systematically reviews all published studies using neuroscience methods (EEG/MEG/TMS/eyetracking/EMG/fMRI) to examine the integrity of the mirror system in autism. 25 suitable papers are reviewed. T...

In a series of papers, Burdzy et al. introduced the mirror coupling of reflecting Brownian motions in a smooth bounded domain D ⊂ Rd , and used it to prove certain properties of eigenvalues and eigenfunctions of the Neumann Laplaceian on D. In the present paper we show that the construction of the mirror coupling can be extended to the case when the two Brownian motions live in different domain...

This paper describes a novel type of solar concentrator – a mirror symmetrical dielectric totally internally reflecting concentrator (MSDTIRC). This new concentrator type has been designed to satisfy the following objectives: (i) to provide optimum gain in two different planes, therefore increasing the electrical output of a solar photovoltaic (PV) system, and (ii) to reduce the amount of the P...
