Chemometric Amylose Modeling and Sample Selection for Global Calibration Using Artificial Neural Networks

食品科学 2008年第8期29卷 118-124页

Chemometric amylose modeling for global calibration,using whole grain near infrared transmittance spectra and sample selection,was used in an artificial neural network(ANN) ,to assess the global and local models generated,based on samples of newly bred Indica,Japonica and rice. Global sample sets had a wide range of sample variation for amylose content(0 to 25.9%) . the local sample set,Japonica sample,had relatively low amylose content and a narrow sample variation(amylose;12.3% to 21.0%) . For sample selection the CENtER algorithm was applied to generate calibration,validation and stop sample sets. Spectral preprocessing was found to reduce the optimum number of partial least squares(PLS) components for amylose content and thus enhance the robustness of the local calibration. the best model was found to be an ANN global calibration with spectral preprocessing;the next was a PLS global calibration using standard spectra. these results pose the question whether an ANN algorithm with spectral preprocessing could be developed for global and local calibration models or whether PLS without spectral preprocessing should be developed for global calibration models. We suggest that global calibration models incorporating an ANN may be used as a universal calibration model.

CE （=%C＋（1/3）x（%Si）） does not suit experiment results in many cases. In this work, the effect of alloy elements on primary crystal temperature was measured and the relationship between primary crystal temperature （tc） and carbon equivalent （CEL） was investigated. the results show that tc （Celsius degree） = 1650-110 × （%C） -25 × （%Si）＋3 × （%Mn） -35 × （%P） -71 × （%5）-2 × （%Ni） -7 × （%Cr）; CEL=%C ＋ 0.23×（%Si）-0.03× （%Mn）＋0.32×（%P）＋0.64×（%S）＋0.02×（%Ni）＋0.06×（%Cr）. that is, in hypo eutectic composition, carbon equivalent should be calculated with CEL=%C＋ 0.23×（%Si）, not with CE=%C＋（1/3） x（%Si）.

Radiation therapy has been shown to be adaptable for various stages of hepatocellular carcinoma

引用

World Journal of Gastroenterology 2015年第1期21卷 94-101页

作者： Yasuteru kondo Osamu kimura tooru Shimosegawa Division of Gastroenterology Tohoku University HospitalSendai 980-8574Japan

In addition to surgical procedures, radiofrequency ablation is commonly used for the treatment of hepatocellular carcinomas(HCCs) of limited size and number. transcatheter arterial chemoembolization(tACE), using iodized poppy seed oil, Lipiodol and anticancer drugs, has been actively performed for the treatment of unresectable HCC, particularly in Asian countries. Recently, Sorafenib become available for advanced HCCs when the liver is still sufficiently functional. Sorafenib is an oral multikinase inhibitor with antiproliferative and antiangiogenic effects. However, the effect of sorafenib seems to be inadequate to control the progression of HCC. Radiation therapy(Rt)for HCC has a potential role across all stages of HCC. However, Rt is generally not considered an option in HCC consensus documents or national guidelines, primarily because of insufficient supporting evidence. However, the method of Rt has much improved because of advances in technology. Moreover, combined treatment of Rt plus other treatments(tACE, sorafenib and chemotherapy etc.) has become one of the alternative therapies for HCC. therefore, we should understand the various kinds of Rt available for HCC. In this review, we focus on various kinds of external beam radiation therapy.

1 Results When a C60 film was irradiated with electron-beam (EB) with an incident energy of 3 kV, a peanut-shaped C60 polymer with metallic properties was formed[1], as shown in Fig.1. to elucidate the origin of the metallic properties of the peanut-shaped polymer, we examined the valence photoelectron spectra of the polymer using in situ high-resolution photoelectron spectroscopy and found that the electronic states of the polymer came across the Fermi level (EF)[2]. Interestingly, the spectral shape i...

Recently we have constructed two facilities for generating photon beams in the MeV and sub-MeV energy regions by means of the Compton backscattering with a laser and an electron beam at SPring-8 and at kansai Photon Science Institute of Japan Atomic Energy Agency(kPSI-JAEA). the MeV-photon source at SPring-8 consists of a continuous-wave optically-pumped far infrared laser with a wavelength of 118.8 μm and an 8 GeV stored electron beam. Present MeV-photon flux is estimated to be 1.3×103 photons/s. On the other hand,the sub-MeV-photon source at kPSI-JAEA consists of a pulse Nd∶YAG laser with a wavelength of 1 064 nm and a 150 MeV electron beam accelerated by microtron. In the first trial of the photon production in this source,backscattered photon flux is estimated to be 20 photons/pulse. Both the Compton backscattered photon sources have possibilities to be used for new tools in various fields such as nuclear physics,materials science,and astronomy.
