沉积盆地中普遍存在异常高压,库车前陆盆地克拉苏构造带经历了多期构造运动,纵向发育多套压力系统,超压成因机制差异化显著,钻井施工难度大。因此,地层压力准确预监测对钻井工程参数、泥浆性能、井身结构优化及安全高效钻井意义重大。本文通过地震、测井、钻井资料研究基础上,开展了克拉苏构造带超压成因机制以及纵横向压力分布特征研究,基于传统dc指数压力预监测方法,引入全烃校正系数创新优化了dc指数计算模型,提高了准确性和时效性,通过10口井的现场应用表明,该方法符合率高,计算结果相对误差为平均5.7%,效果较好,适用于复杂成因和地层,能够为塔里木油田钻井现场规避井漏、卡钻等风险提供及时有效的科学依据。

Due to the complexity of emotional expression, recognizing emotions from the speech is a critical and challenging task. In most of the studies, some specific emotions are easily classified incorrectly. In this paper, we propose a new framework that integrates cascade attention mechanism and joint loss for speech emotion recognition (SER), aiming to solve feature confusions for emotions that are difficult to be classified correctly. First, we extract the mel frequency cepstrum coefficients (MFCCs), deltas, and delta-deltas from MFCCs to form 3-dimensional (3D) features, thus effectively reducing the interference of external factors. Second, we employ spatiotemporal attention to selectively discover target emotion regions from the input features, where self-attention with head fusion captures the long-range dependency of temporal features. Finally, the joint loss function is employed to distinguish emotional embeddings with high similarity to enhance the overall performance. Experiments on interactive emotional dyadic motion capture (IEMOCAP) database indicate that the method achieves a positive improvement of 2.49% and 1.13% in weighted accuracy (wa) and unweighted accuracy (UA), respectively, compared to the state-of-the-art strategies.

目的探讨食管鳞癌根治性放化疗后局部复发病例的胶原纤维变化,以及不同挽救方式的不良反应和生存率差异,为挽救治疗方案的选择提供参考。方法回顾性收集2015年1月—2022年9月在武汉大学人民医院肿瘤中心接受根治性放化疗,并出现局部复发的137例食管鳞癌患者的病历资料。用Masson染色法测定不同复发时间病例的石蜡样本中胶原纤维表达,应用图像分析软件对胶原纤维的平均光密度值进行半定量分析。依据复发之后的挽救治疗方式,将患者分为挽救性手术组、二程放化疗组和免疫化疗组,分析三组患者生存率以及食管气管瘘、出血、心包积液、放射性肺炎、放射性食管炎等不良反应的发生率,用Kaplan-Meier法进行生存分析,log-rank检验分析组间生存率的差异。结果复发食管鳞癌中的胶原纤维表达量较原发食管鳞癌明显增高;胶原纤维表达随着复发时间的延长而逐渐减弱,7年后复发病例中的胶原纤维表达量和原发食管鳞癌类似。患者的1、2、3年生存率在挽救性手术组为47%、30%、20%,二程放化疗组为50%、27%、15%,免疫化疗组为72.5%、50%、50%,免疫化疗组患者的生存情况具有优于挽救性手术组和二程放化疗组的趋势,但差异无统计学意义。结论根治性放化疗后复发的食管鳞癌中富含胶原纤维,随着复发间隔时间延长,胶原纤维表达量减少;采用挽救性手术、二程放化疗和免疫化疗的挽救治疗方式效果相当。

Based on a combined in-situ calcite U-Pb dating, molecular geochemical correlations of reservoir oil and extract from reservoir rocks, and fluid inclusion analysis, the charge and evolution history of the YJ1X ultra-deep oil reservoir of the Ordovician Yijianfang Formation in the southwestern part of the Tabei Uplift has been determined systematically.(1) The reservoir oil, free oil and inclusion oil have similar geochemical characteristics and are presumably derived from marine source rock deposited in similar sedimentary environment.(2) The reservoir oil, free oil and inclusion oil have similar maturities with calculated equivalent vitrinite reflectance values in the range of 0.80%-0.96%.(3) Two types(group Ⅰ and Ⅱ) of oil inclusion assemblages(OIAs) have been identified in the reservoir, of which group Ⅰ represents the original gas-saturated oil entering the trap during the initial oil charge, whereas group Ⅱ represents undersaturated residual oil retained in the reservoir after minor leakage of light hydrocarbon.(4) The reservoir experienced oil charge only once during the Early Devonian around 425 Ma and has been well preserved after the minor light hydrocarbon leakage in the Middle Devonian. The study shows that there may be old oil and gas accumulations in ultra-deep strata of petroliferous basins with well-developed caprock and stable tectonic background.

采用德尔菲(Delphi)法和层次分析(AHP)法构建3~6岁ASD儿童动作技能测评体系;采用实验法对8名3~6岁轻度ASD儿童进行动作技能、体质水平和脑电图(EEg)的综合分析.结果表明:1)依据儿童生长发育里程碑、动作发展顺序规律、ASD儿童核心症状和生活技能发展,采用Delphi法构建3~6岁ASD动作技能测评体系,包括一级指标4项、二级指标15项、三级指标39项.本研究立足ASD儿童动作技能教育与干预建立测评指标,是针对ASD儿童发育规律和核心症状开展评测→干预→教育→反馈→提升的结合体.测评体系通过信效度检验,具有科学性和实用性,便于一线ASD融合教育工作者开展测评和教育活动.2)ASD儿童存在显著的动作技能、体质水平、脑电活动的异常和低下状态.其动作技能均分由高到低依次为BCS、BMS、OCS、HFS,其中OCS和HFS受认知发展影响大.各脑区多波段的异常激活、delta和theta波能量高,alpha波能量低,导致儿童注意力无法集中、感觉加工异常.体质评分及格率低,影响ASD儿童健康相关入学准备水平和未来参与学校教育的能力.ASD儿童亟待开展以动作技能为切入点的体脑发育综合干预和教育,以促进ASD儿童融入学校教育,获得康复和发展.
