| 1 | Problems in screening colorectal cancer in the elderly显示文摘AIM: To explore the problems in the screening of colorectal carcinoma in the elderly.METHODS: Three models of colorectal cancer prevention were examined: standard screening, active check-up of suspected cases and summons to have endoscopic checkup for previously diagnosed colorectal polyps. The study was performed among three groups of elderly individuals:Group 1 (167 cases), hospitalized asymptomatic individuals without symptoms in large intestines. Group 2 (612 cases):old individuals at home for the aged, out of which 32 showed symptoms of colon disorders; Group 3 (44 cases): elderly people with diagnosed polyps. As a result of 1788rectosigmoidoscopies, we identified 61 individuals with polyps, out of which 44 patients were over 65 years old.However, only 9 of these 44 individuals agreed to have the endoscopy performed again.RESULTS: One cancer and 13 polyps were detected in Group 1, and two polyps in Group 2. However, it should be noted that only eleven individuals from Group 2 agreed to have the endoscopy. In Group 3, there were no relapses of the polyps among the nine individuals who came back for the endoscopy.CONCLUSION: Poor understanding of the screening procedures is one of the greatest problems in early detection of the cancer in the aged. Paradoxically, the cooperation is better with hospitalized patients, than with 'successfully old'persons. | DavidoviM.Mladen Milosevic P.Dragoslav Zdravkovic Sanja Bojic Bozidar Djurica Snezana | 2003 | World Journal of Gastroenterology2003，9，10： | 4 |

| 3 | Analysis of recoverable and permanent components of threshold voltage shift in NBT stressed p-channel power VDMOSFET显示文摘In this study we investigate the dynamic recovery effects in IRF9520 commercial p-channel power vertical double diffused metal–oxide semiconductor field-effect transistors(VDMOSFETs) subjected to negative bias temperature(NBT)stressing under the particular pulsed bias. Particular values of the pulsed stress voltage frequency and duty cycle are chosen in order to analyze the recoverable and permanent components of stress-induced threshold voltage shift in detail. The results are discussed in terms of the mechanisms responsible for buildup of oxide charge and interface traps. The partial recovery during the low level of pulsed gate voltage is ascribed to the removal of recoverable component of degradation, i.e., to passivation/neutralization of shallow oxide traps that are not transformed into the deeper traps(permanent component).Considering the value of characteristic time constant associated with complete removal of the recoverable component of degradation, it is shown that by selecting an appropriate combination of the frequency and duty cycle, the threshold voltage shifts induced under the pulsed negative bias temperature stress conditions can be significantly reduced, which may be utilized for improving the device lifetime in real application circuits. | Danijel Dankovi Ninoslav Stojadinovi Zoran Priji Ivica Mani Vojkan Davidovi Aneta Priji Snezana Djoric-Veljkovi Snezana Golubovi | 2015 | Chinese Physics B2015，24，10： | 1 |

| 20 | Dynamical time versus system time in quantum mechanics显示文摘Properties of an operator representing the dynamical time in the extended parameterization invariant formulation of quantum mechanics are studied. It is shown that this time operator is given by a positive operator measure analogously to the quantities that are known to represent various measurable time operators. The relation between the dynamical time of the extended formulation and the best known example of the system time operator, i.e., for the free one-dimensional particle, is obtained. | Duan Arsenovi Nikola Buri Dragomir Davidovi Slobodan Prvanovi | 2012 | Chinese Physics B2012，21，7： | 0 |
