A combination of carbon nanotubes （CNTs） and titanium （Ti） modified with TiO2 nanotubes （TiO2 NTs） was fulfilled with the aim of improving bioactivity of Ti ***,well-ordered TiO2 NTs were prepared by the electrochemical anodization of Ti in an ethylene glycol electrolyte containing 1 wt% Nh4F and 10 wt% h2O at 20 V for 50 min,followed by ***,the carboxylated CNTs were coated onto the TiO2 NTs using electrophoretic deposition （EPD） *** growth of hydroxyapatite （hA） on the samples was investigated by soaking them in simulated body fluid （SBF）.The result showed the CNTs-coated Ti with the modification of TiO2 NTs （CNTs-TiO2 NTs） was more efficient to induce hA formation than the CNTs-coated smooth Ti （CNTs-Ti）.The vitro cell response was evaluated using osteoblast cells （MC3T3-E1）.The good cell proliferation and strong cell adhesion could be obtained on the CNTs-TiO2 *** results indicated that CNT coating on the Ti modified with TiO2 NTs could be potentially useful for the periodontal ligament combination on dental implants.

The goal of this study was to assess the effect of the intermittent combination of an antiresorptive agent （calcitonin） and an anabolic agent （vitamin D3） on treating the detrimental effects of Type 1 diabetes mellitus （DM） on mandibular bone formation and growth. Forty 3-week-old male Wistar rats were divided into four groups： the control group （normal rats）, the control C＋D group （normal rats injected with calcitonin and vitamin D3）, the diabetic C＋D group （diabetic rats injected with calcitonin and vitamin D3） and the diabetic group （uncontrolled diabetic rats）. An experimental DM condition was induced in the male Wistar rats in the diabetic and diabetic C＋ D groups using a single dose of 60 ***-1 body weight of streptozotocin. Calcitonin and vitamin D3 were simultaneously injected in the rats of the control C＋D and diabetic C＋D groups. All rats were killed after 4 weeks, and the right mandibles were evaluated by micro-computed tomography and histomorphometric analysis. Diabetic rats showed a significant deterioration in bone quality and bone formation （diabetic group）. By contrast, with the injection of calcitonin and vitamin D3, both bone parameters and bone formation significantly improved （diabetic C＋ D group）（P 〈 0.05）. These findings suggest that these two hormones might potentially improve various bone properties.

Under dynamic pricing, stable and accurate electricity price forecasting on the demand side is essential forefficient energy management. We have developed a new electricity price forecasting model that providesconsistently accurate forecasts. The base prediction model decomposes the time series using wavelet transformand then predicts it by Long Short-Term Memory. Previous studies using this model have always decomposedtime series in the same way without changing the mother wavelet. however, this makes it difficult to respond tochanges in time series that vary daily or seasonally. Therefore, we periodically switch the mother wavelet, i.e.,flexibly change the time series decomposition method, to achieve stable and highly accurate electricity priceforecasting. In an experiment, the model improved prediction accuracy by up to 42.8% compared to predictionwith a fixed mother wavelet. Experimental results show that the proposed flexible forecasting method canconsistently provide highly accurate forecasts.

This paper reports that α-Bi2O3 microflowers can be synthesized by an extremely simple and easy approach of inducing a reaction through the addition of NaOh aqueous solution to a mixed aqueous solution of Bi(NO3)3·5h2O and hNO3 scanning electron microscopy images of the Bi2O3 microflowers indicate that the Bi2O3 nanorods grew radially from the centre of the microflower to form the microflower shape. The findings of this study show that control of the reaction temperature, reaction time, and raw material mixture ratio plays an important role in the formation of α-Bi2O3 microflowers. It is especially revealed that α-Bi2O3 microflowers can be formed at low temperatures with short reaction times. It has thus far been reported that flower-shaped Bi2O3 particles or their precursors can be synthesized by the addition of additives such as organic molecules or certain inorganic ions. The present work reports on the discovery of ways to synthesize flower-shaped Bi2O3 particles without the use of special additives.

helicobacter pylori (h. pylori) infection is well known to be associated with the development of precancerous lesions such as chronic atrophic gastritis (AG), or gastric intestinal metaplasia (GIM), and cancer. Various molecular alterations are identified not only in gastric cancer (GC) but also in precancerous lesions. h. pylori treatment seems to improve AG and GIM, but still remains controversial. In contrast, many studies, including meta-analysis, show that h. pylori eradication reduces GC. Molecular markers detected by genetic and epigenetic alterations related to carcinogenesis reverse following h. pylori eradication. This indicates that these changes may be an important factor in the identification of high risk patients for cancer development. Patients who underwent endoscopic treatment of GC are at high risk for development of metachronous GC. A randomized controlled trial from Japan concluded that prophylactic eradication of h. pylori after endoscopic resection should be used to prevent the development of metachronous GC, but recent retrospective studies did not show the tendency. Patients with precancerous lesions (molecular alterations) that do not reverse after h. pylori treatment, represent the “point of no return” and may be at high risk for the development of GC. Therefore, earlier h. pylori eradication should be considered for preventing GC development prior to the appearance of precancerous lesions.

A long-pulse plasma discharge for more than 30 min. was achieved on the Large helical Device （LhD）. A plasma of ne = 0.8 × 10^19 m^-3 and T10 = 2.0 keV was sustained with PICh = 0.52 MW, PECh = 0.1 MW and averaged PNBI = 0.067 MW. Total injected heating energy was 1.3 G J, which was a quarter of the prepared RF heating energy. One of the keys to the success of the experiment was a dispersion of the local plasma heat load to divertors, accomplished by shifting the magnetic axis inward and outward.

[1]Ionospheric disturbances in the Southeast Asian region during the super magnetic storm of 20-22 November 2003 were investigated through an ionosonde chain and a GPS network assisted by the space-borne *** early stage of the storm in the postsunset sector,large enhancements in the critical frequency of F layer and total electron content were observed at northern crest region of the equatorial ionization anomaly(EIA), which might be produced by both the storm meridional wind superimposed with traveling atmospheric disturbances and prompt penetration electric field(PPE).During the main phase of the storm when interplanetary magnetic field started a 12-h southward turning, equatorial ionosphere was elevated to a very high level which should be most probably caused by a long-duration PPE ***,at mid-low latitudes,ionosphere witnessed an initial simultaneous decrease then followed by drastic increases,which is very different from the past observations in this region(Reddy and Nishida,1992). Combined analysis of the data from the ionosonde and other space-based measurement shows that for the present case the penetration efficiency of the interplanetary electric field(IEF) to the equatorial ionosphere was larger at night than in the daytime,which agrees with the results of Fejer et al.(2007) showing the ratios of PPE and IEF changes were highly variable with the local *** the recovery phase,EIA was severely inhibited owing to a wind convergence and possibly because of the westward disturbance dynamo electric field.

In the Large helical Device （LhD）, two different divertor configurations, i.e. helical divertor （hD） and local island divertor （LID）, are utilized to control the edge plasma. The hD with two X-points is an intrinsic divertor for heliotron devices, accompanied with a relatively thick ergodic layer outside the confinement region. Edge and divertor plasma behavior from low density to high density regimes is presented, referring to the divertor detachment. The effect of the ergodic layer on the edge transport is also discussed. On the other hand, the LID is an advanced divertor concept which realizes a high pumping efficiency by the combination of an externally induced magnetic island and a closed pumping system. Experimental results to confirm the fundamental divertor performance of the LID are presented.
