近年来我国水产品出口贸易逐渐面临竞争优势缩小、出口增速落后于进口增速、外需疲软的困境,2022年首次由贸易顺差转为贸易逆差,而RCEP(Regional Comprehensive Economic Partnership,区域全面经济伙伴关系)的签署和生效将为中国水产品的出口贸易带来新的机遇。依据2006-2021年中国与RCEP 13个成员国的面板数据,构建随机前沿引力模型和贸易非效率模型实证分析我国与RCEP其他成员国水产品出口贸易潜力。结果表明,中国渔业产值、贸易伙伴国GDP、进口国人口规模均会促进中国水产品出口,而中国人口规模和水产品产量的下降、贸易伙伴国较低水平的货币自由度会阻碍中国水产品的出口;在13个成员国内,对新西兰、韩国、澳大利亚、日本等发达国家的出口效率显著高于发展中国家;而对泰国、菲律宾、马来西亚、印度尼西亚、日本、韩国的出口潜力值较高,贸易扩展空间巨大。基于结论,有针对性的提出要提升我国水产品的国际竞争力,遵循“互利共赢”的原则,创造更加便利化的贸易政策和更加开放的贸易环境,不断提高生产效率、贸易效率和产品质量,加快推进贸易便利化改革,提高中国水产品对RCEP各国的出口效率和出口潜力。

Background:Surgical management of adult slow-transit constipation(ASTC)can be effective for patients with intractable *** study aimed to evaluate whether barium-strip examination and selective colectomy improved post-operative outcomes in ASTC patients in comparison with subtotal ***:A retrospective cohort study of 53 cases with refractory ASTC was conducted between June 2008 and June *** were evaluated by the barium-strip technique,colonoscopy,defecography and anorectal *** in the standard group underwent laparoscopic subtotal colectomy and patients in the laparoscopic selective colectomy(LSC)group underwent LSC at the precise location identified by barium *** bowel movements,the Wexner Constipation Scale and the Gastrointestinal Quality of Life Index(GIQLI)were assessed post-operatively at 3,6,12 and 24 ***:A total of 49 patients were included in the *** median follow-up was 37 months(range,26–60 months).The mean post-operative hospital stay was 12 days and similar between groups(P=0.071).The length of colon resection,operative time and intra-operative blood loss were reduced in the LSC group(all P<0.05).No major complications occurred.A similar number of patients(24 in the standard group and 25 in the LSC group)exhibited hypoganglionosis or aganglionosis in the colon-wall muscle layer(P=0.986).Although there were no significant differences in post-operative spontaneous bowel movements and the Wexner Constipation Scale between the two groups,the mean GIQLI of the LSC group was significantly higher at 3,6 and 24 months post-operatively(all P<0.05).Conclusions:LSC based on barium-strip examination is an appropriate modality for treating ASTC.

为解决现有机理模型参数多且取值误差大导致的模型精度低、数据模型构建简易不能揭示钻削机理等问题,开展了基于机理与数据驱动的CFRP钻削轴向力建模研究。通过对现有CFRP钻削力模型进行修正,得到适用性更广、精度更高的轴向力机理模型。基于神经网络和实验数据构建轴向力机理模型预测偏差补偿器,采用钻削机理与钻削数据联合驱动的方式建立了CFRP钻削轴向力模型。经验证,新建立的模型可在机理模型的基础上进一步提升预测精度,在样本数据集和随机数据集中,预测平均相对误差分别为机理模型的1/8和1/3。

作者： qiu Bing-sen Ni hong-zhen Dermatopathologic Research Laboratory Institute of Dermatology Hua Shan Hospital Shanghai 200040 Unit of DNA Flow Cytometry Cancer Hospital Shanghai Medical University

DNA content and cell cycle distributions in paraffin-embedded blocks of 111 skin biopsy specimens of 70 patients with cutaneous malignant lymphomas (CML) and 41 patients with cutaneous pseudolymphomas (CPL) including chronic actinic dermatitis (CAD) were estimated by DNA flow cytometry. A statistical significant difference between DNA indices (DIs) or proliferative indices (PIs) for CML including mycosis fungoides (MF) II, MF III, Sezary’s syndrome (SS), cutaneous peripheral T-cell lymphomas other than MF and SS, cutaneous germinal center cell-derived lymphomas and cutaneous genuine histiocytic lymphoma from CPL. DIs were also helpful in differentiating MF I from CPL. There was a linear relationship between DIs and PIs, both of which had a parallel relationship to the degrees of malignancy and mortality of varieties of CML. The finding of aneuploidy is likely to be useful in differentiating CML from CPL. It is worth noting that DIs, PIs and proportions of aneuploidy in CAD were all higher than those of higher malignancy of CML. These data could not be considered as markers of malignancy.

A new mechanism for the generation of high intensity speckles by coupling of overlapping beams is discovered and studied in *** three-dimensional simulations,the coupling of overlapping beams smoothed by phase plates and by polarization smoothing are investigated in the regime relevant to inertial confinement fusion *** is found that the intensity distribution of the laser beam spot can be changed by nonuniform spatial phase modulation,and the speckles formed by the phase plate can be split into smaller speckles with higher intensities,which is favorable for the generation of laser plasma *** Brillouin scattering is compared in simulations with and without coupling of the overlapping incident beams,and the results confirm the enhancement of stimulated Brillouin scattering due to this mechanism.

Despite the advantages of all-weather and all-day high-resolution imaging, synthetic aperture radar(SAR) images are much less viewed and used by general people because human vision is not adapted to microwave scattering phenomenon. However, expert interpreters can be trained by comparing side-byside SAR and optical images to learn the mapping rules from SAR to optical. This paper attempts to develop machine intelligence that is trainable with large-volume co-registered SAR and optical images to translate SAR images to optical version for assisted SAR image interpretation. Reciprocal SAR-optical image translation is a challenging task because it is a raw data translation between two physically very different sensing modalities. Inspired by recent progresses in image translation studies in computer vision,this paper tackles the problem of SAR-optical reciprocal translation with an adversarial network scheme where cascaded residual connections and hybrid L1-GAN loss are employed. It is trained and tested on both spaceborne Gaofen-3(GF-3) and airborne Uninhabited Airborne Vehicle Synthetic Aperture Radar(UAVSAR) images. Results are presented for datasets of different resolutions and polarizations and compared with other state-of-the-art methods. The Frechet inception distance(FID) is used to quantitatively evaluate the translation performance. The possibility of unsupervised learning with unpaired/unregistered SAR and optical images is also explored. Results show that the proposed translation network works well under many scenarios and it could potentially be used for assisted SAR interpretation.
