We report on high-field electron spin resonance studies of two iridium hexahalide compounds ${({\mathrm{NH}}_{4})}_{2}{\mathrm{IrCl}}_{6}$ and ${\mathrm{K}}_{2}{\mathrm{IrCl}}_{6}$. In the paramagnetic state, our measurements reveal isotropic $g$ factors $g=1.79(1)$ for ${\mathrm{Ir}}^{4+}$ ions, in agreement with their cubic symmetries. Most importantly, magnetically ordered we observe magnon ...

The aim is to study the density, isodose depths, and doses at different points in slab-pinewood-slab (SPS) phantom, solid phantom SP34 (made up of polystyrene), and chest level of actual patient for developing heterogeneous chest phantom mimicking thoracic region of human body. A 6 MV photon beam of field size of 10 cm × 10 cm was directed perpendicular to the surface of computed tomography (CT...

introduction: in diagnostic and therapeutic procedures, dosimetric studies are performed on the dosimetric systems in order to comply the radiation safety standards. monte carlo methods are used due to the high complexity and cost of patient-specific phantom construction. the high complexity of the digitized phantoms greatly increases the time and computational task of the monte carlo calculati...

OBJECTIVE To ascertain the existence of contralateral painful muscle areas mirroring phantom pain and to evaluate the short-term effects of anaesthetic vs saline, injected contra notlaterally to control phantom and phantom limb pain. DESIGN Double-blinded cross-over study. SETTING Inpatients; rehabilitation institute. PARTICIPANTS Eight lower limb amputees with phantom limb pain in the pa...

Te-impurity-incorporated ${\mathrm{Sb}}_{2}{\mathrm{Te}}_{3}$, i.e., ${\mathrm{Sb}}_{2}{\mathrm{Te}}_{3}+x\phantom{\rule{0.16em}{0ex}}\mathrm{mol}\phantom{\rule{0.16em}{0ex}}%$ Te ($x=0$, 4, 6, and 9) composites were synthesized by solid-state reaction technique. Analysis of x-ray diffraction indicates not only impurity as a second phase but also doping via suppression inherent vacancies in the...

Purpose: Fiber carbon is the most common material used in treating couch as it causes less beam attenuation than other materials. Beam attenuation replaces build-up region, reduces skin-sparing effect and causes target volume under dosage. In this study, we aimed to evaluate beam attenuation and variation of build-up region in 550 TxT radiotherapy couch.Materials and Methods: In this study, we ...

The phantom decoy asymmetrically dominates a target and leads to an increase in the choice proportion of the target when participants are instructed that the decoy is unavailable. To investigate the influence of deliberation time on this effect, we assigned 208 undergraduates to three time pressure levels (4 s, 6 s, and baseline). Participants had to solve 6 hypothetical purchase tasks with thr...

background: attenuation coefficient (μ) plays an important role in calculations of treatment planning systems, as well as determination of dose distributions in external beam therapy, dosimetry, protection, phantom materials and industry. so, its exact measurement or calculation is very important. the aim of this study was to evaluate the μ in different points in the water phantom analytically ...

Background: The dynamic phantom is one of the best tools to study the impact of motion on tumor target delineation and absorbed dose verification during dose delivery. Materials and Methods: this study, a 6-DOF (degrees of freedom) phantom was designed following the stacked serial kinematics and assembled by six commercial motion stages to generate 6-DOF motion, which were RotX (pitch, around X...
