PURPOSE To quantify the dosimetric impact of applicator displacements and applicator reconstruction-uncertainties through simulated planning studies of virtual applicator shifts. MATERIAL AND METHODS Twenty randomly selected high-dose-rate (HDR) titanium tandem-and-ovoid (T&O) plans were retrospectively studied. MRI-guided, conformal brachytherapy (MRIG-CBT) plans were retrospectively generat...

Pairs trading attempts to use the idea of relative pricing, that is, if two securities have similar characteristics, then prices both must be more or less same. With promotion carbon neutrality, green transformation brown assets has become a hot topic. Through series steps including selection, co-integration coefficients calculation, mean-reverting examination, threshold parameters determinatio...

objective: the study evaluated the efficacy of oral calcium carbonate supplement on leg pain in pregnancy and nursing period. materials and methods: a total number of 176 women at third trimester of pregnancy or nursing period till to one year after delivery with complaint of leg pain, low back pain (lbp), and posterior pelvic pain (ppp) were evaluated for distinct primary causes and were exclu...

Paramagnetic relaxation enhancement (PRE) measurements on (1)H nuclei have the potential to play an important role in NMR structure determination of macromolecules by providing unique long-range (10-35 A) distance information. Recent methodological advances for covalently attaching paramagnetic groups at specific sites on both proteins and nucleic acids have permitted the application of the PRE...

We show that a whole class of quantum actions for dilaton-gravity, which reduce to the CGHS theory in the classical limit, can be written as a Liouville-like theory. In a sub-class of this, the field space singularity observed by several authors is absent, regardless of the number of matter fields, and in addition it is such that the dilaton-gravity functional integration range (the real line) ...

In interactive applications such as games, particle-based liquids are often used for simulation. Such liquids are rendered with only a single refraction at the front-facing surface, which damages photorealism because it cannot express the thickness of liquid. In this paper, we propose an approach to render particle-based liquid with twice refraction at frontand back-facing surfaces in real time...

The paper presents an in-depth analysis on IEEE 802.11 DCF in the presence of noise. Based on the analysis, the Back to back Retransmission (BR) scheme is proposed. The main idea of the new scheme is to adopt different MAC protocol behaviors to the failures caused by collisions and those by channel errors. Based on the mathematical models, system saturation throughputs and maximum achievable th...

This paper deals with artificial neural network (ANN) architecture, the multilayer Feed-forward (MLFF) network with back propagation learning. The training of an artificial neural network involves two passes. In the forward pass, the input signals propagate from the network input to the output. In the reverse pass the calculated error signals propagate backwards through the network where they a...

We derive an analytical expression for the two-gluon production in the pA (lightheavy) collisions, and focus specifically on the rapidity dependent part. We approximate the gauge field from the heavy target as the Color Glass Condensate which interacts with the light projectile whose source density allows for a perturbative expansion. We discuss the longitudinal correlations of produced particl...

The density of states (DOS) of crystalline silicon changes with the introduction of dopants due to the formation of an impurity band and band tails. Until now, the DOS of undoped silicon has been used to model silicon devices, regardless of the doping level. This approximation may not be satisfactory for the emitter and back surface field regions of silicon solar cells. Therefore, we measured t...
