FACTORS INFLUENCING THE EFFECT OF RADIOIMMUNOTHERAPY ON LIVER CANCER

Factors influencing the therapeutic effect of radiolmmunotherapy with 131I labeled anti- human hepa-tocellular carcinoma (HCC) ferritin antibody (131I -FtAb) on thirty three patients with surgically proven unresectable HCC were studied. Multi- variable analysis with Cox' s regression model revealed that the statistically sig-nifieant factors include tumor size, activity of 131I administered each time and the second-look resection. Survival of patients with tumor diameter less than 10 cm was higher than that of patients with tumor diameter more than 10 cm (1-year survival; 84% versus 50%) 3-year survival; 63% versus 9% ). Patients administered with 5. 55×108 Bq to 9. 25× 10(?) of 131I-FtAb each time yielded better effect than those administered with more than 9. 25×108 Bq of 131I -FtAb (1-year, survival: 86% ver- sus 55%; 3-year survival: 50% versus 18%). When tumor shrank, patients underwent second-look resection had a higher survival than those without receiving second- look resection (1- year survival, 80%versus 66 %; 3-year survival; 80% versus 11%).

Influence of Tilted Angle on Effective Linear Energy Transfer in Single Event Effect Tests for Integrated Circuits at 130 nm Technology Node

A heavy-ion irradiation experiment is studied in digital storage cells with different design approaches in 130？nm CMOS bulk Si and silicon-on-insulator （SOI） technologies. The effectiveness of linear energy transfer （LET） with a tilted ion beam at the 130？nm technology node is obtained. Tests of tilted angles θ=0 ° , 30 ° and 60 ° with respect to the normal direction are performed under heavy-ion Kr with certain power whose LET is about 40？MeVcm 2 /mg at normal incidence. Error numbers in D flip-flop chains are used to determine their upset sensitivity at different incidence angles. It is indicated that the effective LETs for SOI and bulk Si are not exactly in inverse proportion to cosθ , furthermore the effective LET for SOI is more closely in inverse proportion to cosθ compared to bulk Si, which are also the well known behavior. It is interesting that, if we design the sample in the dual interlocked storage cell approach, the effective LET in bulk Si will look like inversely proportional to cosθ very well, which is also specifically explained.

Modeling the Synergetic Effect of Various Factors on Chloride Transport in Nonsaturated Concrete

Diffusion has been systematically described as the main mechanism of chloride transport in reinforced concrete（RC） structure, especially when the concrete is in a saturated state. However, the single mechanism of diffusion is not able to describe the actual chloride ingress in the nonsaturated concrete. Instead, it is dominated by the interaction of diffusion and convection. With the synergetic effects of various factors taken into account, this study aimed to modify and develop an analytical convection- diffusion coupling model for chloride transport in nonsaturated concrete. The model was verified by simulation of laboratory tests and field measurement. The results of comparison study demonstrate that the analytical model developed in this study is efficient and accurate in predicting the chloride profiles in the nonsaturated concrete.

Identification of Connection Flexibility Effects Based on Load Testing of a Steel-Concrete Bridge

In the case of composite girders, an effective cooperation of both parts of the section is influenced by deformability of connectors. Limited flexural stiffness of welded studs, used commonly in bridge structures, does not provide full interaction of a steel beam and a concrete slab. This changes strain distribution in cross-sections of a composite girder and results in redistribution of internal forces in steel and concrete element. In the paper partial interaction index defined on the basis of a neutral axis position, which can be used for verification of steel-concrete interaction in real bridge structures rather than in specimens is proposed. The range of the index value changes, obtained during load testing of a typical steel-concrete composite beam bridge, is presented. The investigation was carried out on a motorway viaduct, consisting of two parallel structures. During the testing values of strains in girders under static and quasi-static loads were measured. The readings from the gauges were used to determine the index, characterizing composite action of the girders. Results of bridge testing under movable load, changing position along the bridge span is presented and obtained in-situ influence functions of strains and index values are commented in the paper.

Synergistic influence of the capture effect of western flower thrips(Frankliniella occidentalis)induced by proportional yellow-green light in the greenhouse

To clarify the influence of yellow,green,and proportional yellow-green light on the capture effect,western flower thrips,Frankliniella occidentalis(Pergande),were captured using different self-made light sources in a greenhouse.The bio-activity capture effect of thrips was regulated by light and analyzed to determine the reasons for the changes in their capture by light.The results showed that the thrips’capture effect induced by different light sources with the same brightness was positively correlated with night temperature.When the average night temperature was 27℃(19:00-21:30),the capture effect was optimal,indicating that the coupling effect of light temperature can regulate the capture effect of thrips.Green light intensified and yellow light inhibited the visual trend sensitivity of thrips to yellow-green light of differing proportions.The capture effect trapped by a green-yellow light ratio of 4:1 was optimal(1088.00 individuals in night time),while that of yellow light was the worst(456.67 individuals/night),thus,indicating that visual trend sensitivity of thrips to green light was higher than that of yellow light.Such differences originated from the differences in the photoelectric thermal conversion effect of spectral optical properties,and the spectral photo-thermal effect was the main reason that thrips produced a light-trapped behavior.Night light enhanced the sensitivity of thrips’responses to a white adhesive board during the daytime,and the effect of yellow light intensity was the strongest(1563.00 individuals in the daytime),while that of green light was the weakest(75.33 individuals in the day time).Additionally,yellow light intensified while green light inhibited the regulatory effect of different proportions of yellow-green light on the bio-activity of thrips.However,the capture effect of day and night corresponding to 4:1 green-yellow light was the best(2019.67 individuals in day and night).The function of the photo-thermal effect on the capture effect of thrips was affected by the decrease in night temperature,but the photo-electro-thermal effects of night light intensified the bio-activity of thrips in the daytime and enhanced their color sensitivity.The results provide a theoretical basis for the development of pest light induction equipment.

Influence path and effect of climate change on geopolitical pattern

Marked by the UN Climate Change Conference in Copenhagen 2009, climate change is shaping the new pattern for future geopolitics with unprecedented drive. Climate change has surpassed the category of pure environment problem and become a focal issue in international relations. Driven by climate change, new changes have taken place in the evolution of geopolitical pattern. (1) Geopolitical contention expands into new fields and regions. (2) Measures and tools of geopolitical contention become more diversified. (3) Main bodies of geopolitical gambling are divided into different groups. With the development of politicization, climate change has become the significant driving force that can influence the evolution of geopolitical pattern. Measures, sphere and contents of geopolitical contention changed dramatically, carbon emission permits, carbon tariff and new energy technology turned into the key points of geopolitical contention. Climate change acts on the evolution of geopolitical pattern through three main paths: "Feedback effect", "Trace back effect", and "Ripple effect", and they exert influence on geopolitical pattern with three impacts: "Depression effect", "Traceability effect", and "Diffusion effect". We draw several conclusions from the analysis: (1) Climate change gradually becomes one of the most active driving forces to impact on the evolution of geopolitical pattern in the present world and it diversifies the geopolitical targets. (2) Climate change generates new geopolitical tools. The developed countries use climate change as a "Lever" to pry strategic resources like energy and grain and the geopolitical means are in a more secretive way. (3) Low-carbon technology, with new energy technology as the core, becomes the key factor of geopolitical influence and power transition. Those who can take advantage of new energy technologies will occupy the leading position in future's climate change negotiations and geopolitical competition.

Joint model of user check-in activities for point-of-interest recommendation

With the rapid development of location-based networks, point-of-interest（POI） recommendation has become an important means to help people discover interesting and attractive locations, especially when users travel out of town. However, because users only check-in interaction is highly sparse, which creates a big challenge for POI recommendation. To tackle this challenge, we propose a joint probabilistic generative model called geographical temporal social content popularity（GTSCP） to imitate user check-in activities in a process of decision making, which effectively integrates the geographical influence, temporal effect, social correlation, content information and popularity impact factors to overcome the data sparsity, especially for out-of-town users. Our proposed the GTSCP supports two recommendation scenarios in a joint model, i.e., home-town recommendation and out-of-town recommendation. Experimental results show that GTSCP achieves significantly superior recommendation quality compared to other state-of-the-art POI recommendation techniques.
