Tremendous advances have been made in recent years addressing the key obstacles to safe performance and introduction of human natural orifice transluminal endoscopic surgery (NOTES). Animal studies have focused on identifying optimal solutions to these obstacles, in particular methods of creating transluminal access,safe closure of the point of access, and development of a multitasking platform with dedicated instruments. whether the performance data generated from these animal studies can be reproduced in humans has yet to be determined. Reports of human NOTES procedures are emerging, and the possibility of accomplishing human NOTES based on existing technology has been demonstrated. However, dedicated platforms and devices are still lacking to allow for pure NOTES procedures, and whether NOTES can deliver the postulated benef its of earlier recovery and improved cosmesis remains uncertain.

Structural and optical properties of vertically aligned InAs quantum dots (QDs) were embedded in Al0.5Ga0.5As spacer layers. The aligned QDs were grown at 520℃ in the Stranski-krastanow (S-k) growth mode of molecular beam epitaxy. To impro ve QD characteristics, we employed a size- and density-controlled growth procedu re in the upper layers. Measurements by reflection high-energy electron diffract ion (RHEED) and atomic force microscopy (AFM) showed that both the size and dens ity of the QDs. The temperature dependence of the wavelength-integrated photolum inescence (PL) intensity revealed the InAs QD emission.

The morphology of chromium in chilled Cu-Cr alloys with 0.14%-2.0% Cr has been studied. The results showed that eutectic Cr phase takes a fibrous shape, and pre-eutectic Cr is dendritic in the studied chilled Cu-Cr alloy. During solute treatment of the eutectic and super-eutectic Cu-Cr alloys, only part of chromium particles dissolved in copper phase, some fiber and dendritic chromium still remained. Forging before solute treatment can reduce the size of primary Cr particles, which benefits the aging structure.

现有的风速预测方法大多是确定性的点预测,无法描述风速的随机性。针对该问题,建立基于变分模态分解(VMD)和蝙蝠算法-相关向量机(BA-RVM)的短期风速区间预测模型。对原始风速序列进行变分模态分解获得多个子序列;采用样本熵(SE)算法对子序列进行重组得到3类具有典型特性的分量;对各分量采用相关向量机算法分别建立预测模型。为进一步提高预测精度、缩小区间范围,引入蝙蝠算法(BA)对预测模型进行参数优化。将各分量的预测结果进行叠加求和得到一定置信水平下总体的区间预测结果。实际算例结果表明,与现有方法相比,所提区间预测方法的预测精度和区间覆盖率更高,区间宽度更窄。

Crystallization of amorphous silicon（a-Si） which starts from the middle of the a-Si region separating two adjacent metal-induced crystallization（MIC） polycrystalline silicon（poly-Si） regions is observed. The crystallization is found to be related to the distance between the neighboring nickel-introducing MIC windows. Trace nickel that diffuses from the MIC window into the a-Si matrix during the MIC heat-treatment is experimentally discovered, which is responsible for the crystallization of the a-Si beyond the MIC front. A minimum diffusion coefficient of 1.84×10^-9cm^2/s at 550℃ is estimated for the trace nickel diffusion in a-Si.

The magnetization measurements of gallium nitride nanoceramics doped with 1% of cerium and sintered under various pressures were reported. It was found that GaN nanoceramics doped with cerium showed paramagnetic behavior in the wide temperature range. Nanoceramics of GaN with 1% of Ce （as undoped GaN） was diamagnetic one, but under certain temperature the paramagnetic properties started to dominate. This crossover temperature was nonlinearly dependent on the pressure applied during the sintering. The fitting of molar magnetic susceptibility allowed to estimate the Curie temperature, Curie constant and diamagnetic part of susceptibility. As it was found, all the samples showed the antiferromagnetic ordering with θp≈-1 k. Also, the effective magnetic moment was estimated for all of the samples. As a result, magnetic moments in terms of Ce ion were notably larger in comparison with those obtained within the Russell-Saunders cou- pling model. we suggested that it was the strong influence of amorphous shell which was rising with the pressure applied during the sintering. Finally, we presented dependences of magnetization as a function of applied field. All the samples manifested weak ferromagnetism at high temperatures and paramagnetic behavior in low temperature region.
