Objective: Radiochromic EBT3 film is a later generation of radiochromic films. The aim of this study is to compare EBT and EBT3 radiochromic films in radiotherapy fields of breast cancer.Methods: A RANDO phantom was irradiated by a 6 MV Siemens Primus linac with medial and lateral fields of radiotherapy of breast cancer. Dosimetry was performed in various points in the fields using EBT and EBT3...

We compare simulations of optical near-fields of single triangular nanostructures with experimental results from a near-field ablation technique on a periodic arrangement of triangles. We find good agreement of the lateral near-field distributions; nevertheless their dependency on the polarization of the incident light differs by 90◦. Upon increasing the lateral distances of the nanotriangle ar...

We study the topographic development of receptive elds by simulating the con tinuum eld equations with learning on a tw odimensional lattice. The observed plasticity reveals a columnar organisation with spatial clustering of receptive eld centres, and the development of orien ted receptiv e elds, if certain conditions ar met.

Like the retinal ganglion cells from which they receive their input, most relay neurons in the lateral geniculate nucleus have ON- or OFF-center receptive fields with antagonistic surrounds. In the cat, neurons with these two types of receptive fields are anatomically intermingled, even though the ON and OFF systems are functionally segregated. In the ferret, there is a sublamination of the ret...

introduction: the septal area is an important telencephalic center that plays a prominent role in the learning, emotional sexual behaviour processes and autonomic functions. this area contains two main divisions; lateral (ls) and medial (ms), that receive numerus afferents from hippocampal formation. this study compares, quantitatively distributional pattern of the afferent neurons to these two...

Three patients were found to have visual field defects which involved homonymous horizontal sectors of the visual fields, thus mimicking field defects associated with lesions of the lateral geniculate nucleus. Computed tomography provided anatomical evidence that the responsible lesion involved the optic radiations rather than the lateral geniculate nucleus.

lateral flow assay, a simple and rapid test to detect various agents; have found many applications in different fields. one of the most important issues in the construction of a lateral flow assay is the increasing of its sensitivity and efficiency by processing of analytical layer. this study, aimed to investigate the performance of, nellulose, nitrocellulose, nylon and pvd as different analyt...

This study reexamined the perceptual equivalence of active and passive touch using a computer-controlled force-feedback device. Nine subjects explored a 6 x 10-cm workspace, with the index finger resting on a mobile flat plate, and experienced simulated Gaussian ridges and troughs (width, 15 mm; amplitude, 0.5 to 4.5 mm). The device simulated shapes by modulating either lateral resistance with ...

When complex values are assigned to the source coordinates in the expressions for the fields radiated by a line or point source in a homogeneous medium, the resulting fields have the form of a two-or three-dimensional Gaussian beam. This fact may be utilized to develop results for beam propagation and scattering in inhomogeneous regions from corresponding results for point or line source fields...
