BACKGROUND Although computed tomography (CT) with three-dimensional (3D) rendering of the calcaneus is used for diagnostic evaluation of disorders, morphological measurements for the calcaneus are mostly based on a two-dimensional plane. The purposes of this study were to design a method for 3D morphological measurements of the normal calcaneus based on CT post-processing techniques, to measure...

Necrotizing enterocolitis (NEC) is the most common gastrointestinal disease of prematurely born infants. Maternal milk plays an important protective role against NEC development and is the major source of epidermal growth factor (EGF) for neonates. The aim of this study was to examine the effect of orally administered EGF on the incidence of NEC in a neonatal rat model. Newborn rats were artifi...

Introduction: Electronic portal imaging devices (EPIDs) could potentially be useful for intensity-modulated radiation therapy (IMRT) and VMAT QA. The data density, high resolution, large active area, and efficiency of the MV EPID make it an attractive option. However, EPIDs were designed as imaging devices, not dosimeters, and as a result they do not inherently measure dose in ...

the polarimetric entropy and the alpha angle are two important parameters for analyzing polarimetric synthetic aperture radar data. they demonstrate the degree of randomness in the polarization of the received signal and scattering mechanism of scatterers respectively. recently, there has been an increasing interest in compact polarimetry due to its advantages in comparison with full polarimetr...

Preferential concentration is thought to play a key role in promoting particle growth, which crucial processes such as warm rain formation clouds, planet formation, and industrial sprays. In this work, we investigate preferential using 3D Direct Numerical Simulations adopting the Eulerian-Eulerian two-fluid approach, where particles are treated continuum field with its own momentum mass conserv...

dear editor:   hehua ye and colleagues reported an interesting and rare case of primary conjunctival rhabdomyosarcoma (rms) successfully treated with surgery and chemotherapy in iranian journal of ophthalmology 201123(4):65-68. there are some considerable comments that i would like to point out.   orbital rms is the most common malignant mesenchymal neoplasm of the childhood and may also rarely...

Image focus analysis is an important technique for passive autofocusing and three-dimensional shape measurement. Electronic noise in digital images introduces errors in this technique. It is therefore important to derive robust focus measures that minimize error. In our earlier research, we have developed a method for noise sensitivity analysis of focus measures. In this paper we derive explici...

We study the enforcement of competition policy against collusion under Leniency Programs, which give reduced ̄nes to ̄rms revealing information to the Antitrust Authority. Such programs give ̄rms an incentive to break collusion, but may also have a pro-collusive e®ect, since they decrease the expected cost of misbehaviour. We analyze the optimal policy under alternative rules and with homogeneo...

background: tangential irradiation of intact breast is one of the most common procedures performed in any radiotherapy center. this method is performed by using 2d and 3d treatment planning. the aim of this study was to compare 2d with 3d plans in breast conserving radiotherapy. homogeneity of isodose, and lung received dose were compared. materials and methods: twenty patients with breast canc...

We present an efficient and sensitive hybrid algorithm for local structure alignment of a pair of 3D protein structures. The hybrid algorithm employs both the URMS (unit-vector root mean squared) metric and the RMS metric. Our algorithm searches efficiently the transformation space using a fast screening protocol; initial transformations (rotations) are identified using the URMS algorithm. Thes...
