Influence of dose calculation algorithms on the predicted dose distributions and NTCP values for NSCLC patients

Purpose: To investigate differences in calculated doses and normal tissue complication probability (NTCP) values between different dose algorithms. Methods: Six dose algorithms from four different treatment planning systems were investigated: Eclipse AAA, Oncentra MasterPlan Collapsed Cone and Pencil Beam, Pinnacle Collapsed Cone and XiO Multigrid Superposition, and Fast Fourier Transform Convolut

Production of omega mesons in p plus p, d plus Au, Cu plus Cu, and Au plus Au collisions at root s(NN)=200 GeV

The PHENIX experiment at the Relativistic Heavy Ion Collider has measured omega meson production via leptonic and hadronic decay channels in p + p, d + Au, Cu+ Cu, and Au + Au collisions at root s(NN) = 200 GeV. The invariant transverse momentum spectra measured in different decay modes give consistent results. Measurements in the hadronic decay channel in Cu Cu and Au + Au collisions show that. p

Advancing QCD-based calculations of energy loss

We give a brief overview of the basics and current developments of QCD-based calculations of radiative processes in medium. We put an emphasis on the underlying physics concepts and discuss the theoretical uncertainties inherently associated with the fundamental parameters to be extracted from data. An important area of development is the study of the single-gluon emission in medium. Moreover, est

Electric field driven self-assembly of ionic microgels

We study, using fluorescent confocal laser scanning microscopy, the directed self-assembly of cross-linked ionic microgels under the influence of an applied alternating electric field at different effective packing fractions phi(eff) in real space. We present a detailed description of the contribution of the electric field to the soft interparticle potential, and its influence on the phase diagram

Survival in cancer of unknown primary site: population-based analysis by site and histology

Cancer of unknown primary (CUP) is diagnosed at a metastatic stage, conferring an unfavorable prognosis. The natural history of the disease is poorly understood, which complicates diagnosis, treatment and follow-up. Population-based survival data are lacking regarding location and histology of metastases. From the Swedish Cancer Registry, 18 911 CUP patients were identified between years 1987 and

Increasing wrist fracture rates in children may have major implications for future adult fracture burden.

Background and purpose - Childhood fractures are associated with lower peak bone mass (a determinant of osteoporosis in old age) and higher adult fracture risk. By examining time trends in childhood fracture epidemiology, it may be possible to estimate the vector of fragility fracture risk in the future. Patients and methods - By using official inpatient and outpatient data from the county of Skån

The effect of organizational structure and hoteliers' risk proclivity on innovativeness

The purpose of this article is to examine the impact of organisational structure and hoteliers’ risk proclivity on innovativeness in the context of the Japanese hotel industry. Survey questionnaires were used to collect relevant data from 115 hotels in Japan. Using a multiple regression analysis, the antecedents of innovativeness in the hotel industry are been examined. The findings are mixed with

Emotional tone in young adolescents’ interpersonal relations and its association with deliberate self-harm.

Previous research has shown that a less positive emotional tone in adolescents’ relationships to parents, but not in their relationships to peers, predicts more of behaviour problems and substance use. The purpose of the present study was to replicate these findings, and to extend this research to deliberate self-harm. In a first study with a variable-oriented approach, correlations were analysed

Length of time such civilizations release detectable signals into space, L, pre-1961

This chapter is an overview of the prehistory of L, how people across the globe from our earliest sources to 1961 have tried to understand the beginning and end of history, and the rise and fall of civilizations. Factor L is put into a longer historical context of human conceptions about history, time, and civilization. In focus is the question of how it was possible to formulate L in its modern v

A 3.4mW 65nm CMOS 5th Order Programmable Active-RC Channel Select Filter for LTE Receivers

In this work a low power 5th order chebyshev active-RC low pass filter that meets Rel-8 LTE receiver requirements has been designed with programmable bandwidth and overshoot. Designed for a homodyne LTE receiver, filter bandwidths from 700kHz to 10MHz are supported. The bandwidth of the operational amplifiers is improved using a novel phase enhancement technique. The filter was implemented in 65nm

Geostatistical approach for statistical descripion of uplift pressures: Part I

The possibilities of the use of structural reliability analysis in concrete dam design and assessment is investigated in Sweden. For such analysis, statistical descriptions of the loads and resistances are necessary. Uplift pressure has a large impact on safety, and is difficult to quantify. This paper describes the methodology of a geostatistical approach to simulate the uplift pressure, and an e

Resource allocation and disturbance rejection in web servers using SLAs and virtualized servers

Abstract—Resource management in IT–enterprises gain more and more attention due to high operation costs. For instance, web sites are subject to very changing traffic–loads over the year, over the day, or even over the minute. Online adaption to the changing environment is one way to reduce losses in the operation. Control systems based on feedback provide methods for such adaption, but is in natur

Patterns of Post-Glacial Genetic Differentiation in Marginal Populations of a Marine Microalga

This study investigates the genetic structure of an eukaryotic microorganism, the toxic dinoflagellate Alexandrium ostenfeldii, from the Baltic Sea, a geologically young and ecologically marginal brackish water estuary which is predicted to support evolution of distinct, genetically impoverished lineages of marine macroorganisms. Analyses of the internal transcribed spacer (ITS) sequences and Ampl

From Code Compliance to Holistic Approaches in Structural Design of Bridges

Testing the effect of site selection and parameter setting on REVEALS-model estimates of plant abundance using the Czech Quaternary Palynological Database

REVEALS-based quantitative reconstruction of Holocene vegetation cover (expressed in plant functional types. PFTs) is used in the LANDCLIM project to assess the effect of human-induced land-cover change on past climate in NW Europe. Using the Czech Quaternary Pollen Database, this case study evaluates the extent to which selection of data and input parameters for the REVEALS model applications wou
