introduction patient set-up optimization is required in radiotherapy to fill the accuracy gap between personalized treatment planning and uncertainties in the irradiation set-up. in this study, we aimed to develop a new method based on neural network to estimate patient geometrical setup using 4-dimensional (4d) xcat anthropomorphic phantom. materials and methods to access 4d modeling of motion...

background existence of fluoride in drinking water above the permissible level causes human skeletal fluorosis. objectives electrocoagulation by iron and aluminum electrodes was proposed for removing fluoride from drinking water. materials and methods effects of different operating conditions such as treatment time, initial ph, applied voltage, type and number of electrodes, the spaces between ...

Abstract Radio-frequency (RF) linear multipole traps have been shown to be very sensitive mis-positioning of their electrodes, which results in a symmetry breaking and leads extra local minima the trapping potential as Pedregosa-Gutierrez et al (2018 J. Mod. Opt. 65 529) disturbing operation trap. In this work, we analytically describe RF-potential realistic octupole trap by including lower ord...

(Chest 1993; 103:271-72) T he implantable cardioverter defibrillator (lCD) has become accepted treatment for the management of certain malignant ventricular arrhythmias. ‘ Implantation ofthe lCD usually requires an anterolateral thoracotomy through which the patch electrodes and sensing electrodes are placed, in either an intraor an extrapericardial position, although subcostal and subxiphoid a...

The objective of this experiment was to study the usefulness of bioelectrical impedance analysis (BIA) in determining soft tissue composition (STC) and carcass fat-free mass (CFFM) of Holstein steers at different ages. Growth data and prediction of STC and CFFM were determined for four groups of Holstein steers: 12 of 3 mo, 12 of 6 mo, 15 of 9 mo, and 16 of 12 mo of age. Average weight for anim...

In this paper, the plastic limit load of cylindrical shells with opening subject to combined bending moment and axial force are found by finite element method using ANSYS suite of program. The effect of various parameters such as the geometrical ratios of shell and the shape, size, axial and angular position of the opening on the limit load of cylindrical shells under various loading conditions...

We report on the formulation and electrical control of the position and bandwidth of reflective bandpass filters prepared from cholesteric liquid crystal (CLC) in the infrared (3-5 μm). These filters are prepared from alignment cells employing infrared transparent electrodes and substrates. The optical nature of the electrodes is shown to strongly influence the resulting transmission of the ban...

One of the most important findings in cochlear implant research has been the orderly variation in perceptual characteristics produced by intra­ cochlear electrodes in accordance with the tonotopic organization of the cochlea. The electrical signal dimension of electrode position has there­ fore been used extensively for presenting speech information to cochlear implant patients. This paper desc...

Presence of joints and fractures in rocks strongly influences the behavior of the rock mass by dividing the media into smaller units. These structures intensify the potential instability besides the development of sliding and rotational movements. The assumption of discontinuum media changes the whole analysis conditions in relation to the continuum analysis. Acquisition of geometrical and stru...
