| 1 | Validation of nutritional risk index method against patientgenerated subjective global assessment in screening malnutrition in colorectal cancer patients显示文摘Objective:To validate malnutrition screening tool of nutrition risk index(NRI)against patient-generated subjective global assessment(PG-SGA)as a gold standard tool in colorectal cancer patients before radiotherapy.Methods:Nutritional status of 52 volunteer colorectal cancer patients with a mean age of 54.1±16.8 years who referred to radiotherapy center were assessed by PG-SGA(gold standard method)and NRI.Serum albumin levels of patients were determined by colorimetric method.A contingency table was used to determine the sensitivity,specificity,and predictive value of the NRI in screening patients at risk of malnutrition,in comparison with the PG-SGA in patients before radiotherapy.Results:The findings of PG-SGA and NRI showed that 52%and 45%of patients in our study were moderately or severely malnourished respectively.The NRI had a sensitivity of 66%and a specificity of 60%against PG-SGA.The positive predictive value was 64%and the negative predicative value was 62%.The agreement between NRI and PG-SGA was statistically insignificant(kappa=0.267;P>0.05).Conclusions:The findings of present study showed that the prevalence of malnutrition was high in patients with colorectal cancer.Moreover,NRI method had low sensitivity and specificity in assessing nutritional status of patients with cancer.It seems that the combination of anthropometric,laboratory parameters and a subjective scoring system may be helpful tools in screening of malnutrition in cancer patients. | Elnaz Faramarzi Reza Mahdavi Mohammad Mohammad-Zadeh Behnam Nasirimotlagh | 2013 | Chinese Journal of Cancer Research2013,25,5: | 23 |
| 2 | A generalized supervised classification scheme to produce provincial wetland inventory maps:an application of Google Earth Engine for big geo data processing显示文摘Wetlands are important natural resources due to their numerous ecological services.Consequently,identifying their locations and extents is imperative.The stability,repeatability,cost-effectiveness,multi-scale coverage,and proper spatial resolution imagery of satellites provide a valuable opportunity for their use in various large-scale applications,such as provincial wetland mapping.To do so,it is required to(1)process and classify big geo data(i.e.a large amount of satellite datasets)in a time-and computationally-efficient approach and(2)collect a large amount of field samples.In this study,Google Earth Engine(GEE)and machine learning algorithms were utilized to process thousands of remote sensing images and produce provincial wetland inventory maps of the three Canadian provinces of Manitoba,Quebec,and Newfoundland and Labrador(NL).Additionally,using GEE,a generalized supervised classification method is proposed to produce a regional wetland map from a large area(e.g.,a province)when lacking field samples.In fact,using the field data from only Manitoba and assuming that all wetlands in Canada have similar characteristics,the wetland maps were generated for the other two provinces.The overall classification accuracies for Manitoba,Quebec,and NL were 84%,78%,and 82%,respectively,indicating the high potential of the proposed method for aiding provincial wetland inventory systems. | Meisam Amani Brian Brisco Majid Afshar S.Mohammad Mirmazloumi Sahel Mahdavi Sayyed Mohammad Javad Mirzadeh Weimin Huang Jean Granger | 2019 | Big Earth Data2019,3,4: | 4 |

| 9 | Nanoelectromechanical resonant narrow-band amplifiers显示文摘This study demonstrates amplification of electrical signals using a very simple nanomechanical device.It is shown that vibration amplitude amplification using a combination of mechanical resonance and thermal-piezoresistive energy pumping,which was previously demonstrated to drive self-sustained mechanical oscillation,can turn the relatively weak piezoresistivity of silicon into a viable electronic amplification mechanism with power gains of 420 dB.Various functionalities ranging from frequency selection and timing to sensing and actuation have been successfully demonstrated for microscale and nanoscale electromechanical systems.Although such capabilities complement solid-state electronics,enabling state-of-the-art compact and high-performance electronics,the amplification of electronic signals is an area where micro-/nanomechanics has not experienced much progress.In contrast to semiconductor devices,the performance of the proposed nanoelectromechanical amplifier improves significantly as the dimensions are reduced to the nanoscale presenting a potential pathway toward deep-nanoscale electronics.The nanoelectromechanical amplifier can also address the need for ultranarrow-band filtering along with the amplification of lowpower signals in wireless communications and certain sensing applications,which is another need that is not efficiently addressable using semiconductor technology. | Alireza Ramezany Mohammad Mahdavi Siavash Pourkamali | 2016 | Microsystems & Nanoengineering2016,2,1: | 1 |

| 13 | Modeling frequency distributions of tree height, diameter and crown area by six probability functions for open forests of Quercus persica in Iran显示文摘The prediction of the distribution of quantitative variables in a forest stand is of great interest to forest managers, for the evaluation of forest resources and scheduling of future silvicultural treatments. The aim of this research was to model the distribution of quantitative variables for Quercus persica in open forests in Iran. To investigate the probability distribution of trees in natural stands, 642 trees were selected for measurement using a systematic random sampling method. Selected trees were measured and data were analyzed. Gamma, beta, normal,lognormal, exponential and Weibull probability distributions were fitted to the height distribution of trees. Variables of distribution functions were estimated using the maximum likelihood estimation method. Actual probability and probability which derived from functions was compared using Kolmogorov–Smirnov and Anderson–Darling tests. Beta, Weibull and Weibull probability distributions explained the distributions of tree height, DBH and crown area. | Mehrdad Mirzaei Jalal Aziz Ali Mahdavi Asma Mohammad Rad | 2016 | Journal of Forestry Research2016,27,4: | 1 |

| 19 | Weibel Instability Growth Rate in Magnetized Plasmas with Quasi-Relativistic Distribution Function显示文摘The mechanism of the Weibel instability is investigated for dense magnetized plasmas. As we know, due to the electron velocity distribution, the Coulomb collision effect of electron-ion and the relativistic properties play an important role in such study. In this study an analytical expression for the growth rate and the condition of restricting the Weibel instability are derived for low-frequency limit. These calculations are done for the oscillation frequency dependence on the electron cyclotron frequency. It is shown that, the relativistic properties of the particle lead to increasing the growth rate of the instability. On the other hand the collision effects and background magnetic field try to decrease the growth rate by decreasing the temperature anisotropy and restricting the particles movement. | Sayed Ahmad Hosseini Mohammad Mahdavi | 2016 | Communications in Theoretical Physics2016,65,12: | 0 |
| 20 | Investigation of thermal behavior of energetic and non-energetic binders on luminous efficiency of high performance miniature flares显示文摘Miniature flares containing magnesium/sodium nitrate compounded with different binders were studied for increasing luminosity and luminous efficiency in various fuel oxidizer ratio and flare diameters.Unsaturated polyester, Bisphenol-A epoxy resin, calcium resinate, and nitrocellulose were used as binders for construction the flares. Experimental results showed that luminous efficiency was higher for polyester based flares. Due to the difference in decomposition progress of various binders and the exothermic reaction between binder and oxidizer the luminous efficiency of the mixtures were 31000,28900, 27800 and 25100 cd respectively for polyester, epoxy, calcium resinate, and nitrocellulose. It was found that nitrocellulose as an energetic binder produces the highest light intensity in comparison to other binders, but the burning rate is higher and the burning time is lower than the other binders.Thermal analysis of four binders showed that the heat of reactions was directly related to the amount of light output and luminosity. | Saeid Bagherpour Mohammad Mahdavi Ebrahim Abedini | 2019 | Defence Technology(防务技术)2019,15,2: | 0 |
