Comments on 'Response to "The Phenomenological Theory of Martensite Crystallography (PTMC) versus the Topological Model (TM)"'
No full textIn a paper presented at ICOMAT 2008 [1], it was pointed out that the Topological Model (TM) analysis, in the form that had appeared in the literature to date, contained three errors. The consequences of these errors was that the TM predictions of the interface habit plane - particularly in the case of the analysis based on the 'overlap step height' h and incorporating partitioning - did not agree with those of the Phenomenological Theory of Martensite Crystallography (PTMC). The major consequence of this discrepancy between the two sets of interface habit plane predictions was that the TM version was not consistent with the condition of 'no long range strain' in the habit plane. It was demonstrated that the errors in the TM analysis could be very easily corrected by substituting the 'mean step height' for the 'overlap step height' h in the major equation used to determine the inclination of the interface habit plane to the terrace planes in the two phases. This led to very good agreement between the PTMC and the TM and ensured that there was now no long range strain in the interface habit plane. This ICOMAT 2008 paper has generated a response from the major proponents of the TM [2]. This response concludes that the criticisms in the original paper [1] are 'misguided', that the TM analysis does in fact lead to the correct 'rigorous determination of equilibrium habit planes' and that this state has 'not been correctly determined by Kelly [1]'. The purpose of this paper is to comment on the response by Hirth and Pond [2] and to show that many of their conclusions are based on misconceptions about the PTMC or misunderstandings of the corrections to the TM presented in the original paper [1]
Synthesis optimization and charge carrier transfer mechanism in LiLuSiO<sub>4</sub>:Ce, Tm storage phosphor
No full textLiLuSiO4:Ce and LiLuSiO4:Ce, Tm show very efficient charge carrier storage properties upon beta irradiation after samples have received treatment in vacuum. They outperform the commercial storage phosphor BaFBr(I):Eu2+ in many aspects. The influence of the synthesis conditions, Ce and Tm concentration, nonstoichiometry and codoping with Ca, Hf, Al and Ge are reported. Based on the results of the synthesis optimization, thermoluminescence (TL) emission and TL excitation spectra a mechanism of charge carrier transfer, storage, and recombination during irradiation and thermal or optical readout is proposed.Accepted Author ManuscriptRST/Fundamental Aspects of Materials and EnergyRST/Luminescence Material
The Topological Model (TM) of martensite transformations – Some improvements
No full textA minor, but crucial, modification to the original version of the TM was recently proposed in order to ensure that the model predictions were entirely consistent with those of the phenomenological theory of martensite crystallography (PTMC). In the present paper an analysis based on the principles of the Frank-Bilby equation is used to derive this modified version of the twodimensional TM equation for the habit plane orientation from first principles. A considerably simpler and more accurate expression for the tilt rotation is also presented. Finally, a simple method for using the TM approach to calculate the shape strain, its magnitude and direction is described. The results of the predictions made with this improved version of the TM are compared with those of the original TM and with the corresponding PTMC predictions
Synchronous Colorectal Liver Metastasis: A Network Meta-Analysis Review Comparing Classical, Combined, and Liver-First Surgical Strategies
No full textBackgroundIn recent years, the management of synchronous colorectal liver metastasis has changed significantly. Alternative surgical strategies to the classical colorectal-first approach have been proposed. These include the liver-first and combined resections approaches. The objectives of this review were to compare the short- and long-term outcomes for all three approaches. MethodsA systematic review of comparative studies was performed. Evaluated endpoints included surgical outcomes (5-year overall survival, 30-day mortality, and post-operative complications). Pair-wise and network meta-analysis (NMA) were performed to compare survival outcomes. ResultsEighteen studies were included in this review, reporting on 3,605 patients. NMA and pair-wise meta-analysis of the 5-year overall survival did not show significant difference between the three surgical approaches: combined versus colorectal-first, mean odds ratio (OR) 1.02 (95% CI 0.8-1.28, P=0.93); liver-first versus colorectal-first, mean OR 0.81 (95% CI 0.53-1.26, P=0.37); liver-first versus combined, mean OR 0.80 (95% CI 0.52-1.24, P=0.41). In addition NMA of the 30-day mortality among the three approaches also did not observe statistical difference. Analysis of variance showed that mean post-operative complications of all approaches were comparable (P=0.51). ConclusionThere are considerable differences in the peri-operative management of synchronous CLM patients. This meta-analysis demonstrated no clear statistical surgical outcome or survival advantage towards any of the three approaches. J. Surg. Oncol. 2015 111:341-351. (c) 2014 Wiley Periodicals, Inc

The dependence of light extraction improvement on optimized surface microstructure for AlGaN-based UVC-LEDs considering TM-polarized emission
No full textIn order to improve the light extraction of AlGaN-based short wavelength ultraviolet light emitting diodes (DUC-LEDs), a type of microstructure with high aspect ratio is introduced and optimized on the AlN substrate surface. And, particle swarm optimization (PSO) algorithm is used to inverse design of the surface microstructure to maximize the light extraction efficiency (LEE). Considering that the propagation characteristics of TM-polarized light are different from that of TE-polarized light, the optical field distribution and LEE is analyzed for the UVC-LEDs with different TE-polarized component when the optimized surface microstructure is applied. Furthermore, the preparation process tolerance of the high aspect ratio structure is discussed by calculating the LED's LEE when the structural deviation occurs or morphology changes. Simulation results show that, by using the optimized surface microstructure based on parabola cone array, the LEDs' LEE is increased from 4.4% to 8.7% and from 0.4% to 3.7% for TE-polarized and TM-polarized emission, respectively. In addition, it is demonstrated that the light extraction improvement by the surface microstructure has a good tolerance to the structural deviation and morphology. The results are significant for improving light extraction and realizing high efficient short wavelength AlGaN-based UVC-LEDs by designing surface microstructures.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.ImPhys/Esmaeil Zadeh grou
