电力负荷预测的准确性受到多种因素的干扰,如气候变化、经济发展以及区域差异等,这些因素使得电力负荷呈现出显著的不稳定性和复杂的非线性特征,从而增加了提高预测精度的难度。为了应对这一挑战,本文创新性地引入了一种结合自注意力机制与长短期记忆网络(LSTM)的预测方法。通过在美国某一地区的实际用电负荷数据验证模型,实验结果表明,该方法的决定系数(R2)为0.96,平均绝对误差(MAE)为0.023,均方根误差(RMSE)为0.029,提升了预测的准确性。这不仅证明了所提模型在提高电力负荷预测精度方面的有效性,也为其在船舶电力负荷预测的应用奠定了一定的基础。

目的观察重型颅脑损伤(sTBI)患者去骨瓣减压术后联合应用亚低温疗法和右美托咪定静脉注射效果。方法选择96例sTBI患者,根据治疗方案分为观察组48例、对照组48例。两组均行去骨瓣减压术,术后对照组接受亚低温疗法,观察组在对照组的基础上联合右美托咪定[0.4~0.7µg/(kg·h)]静脉注射治疗。分别于术前(T0)、术后1 d(T1)、术后3 d(T2)、术后7 d(T3)采用格拉斯哥昏迷量表(GCS)评分评估两组创伤严重程度,采用脑室外引流装置及彩色多普勒超声系统检测两组颅内压(ICP)、脑灌注压(CPP)及脑血流量(CBF),采集两组颈内静脉球部及桡动脉血并测算脑氧代谢指标颈静脉血氧饱和度(SjvO_(2))、动脉-颈内静脉血氧含量差(AVDO_(2))及脑氧摄取率(CERO_(2)),采集两组外周静脉血并检测血清胶质纤维酸性蛋白(GFAP)。观察两组术后7、30 d死亡及重残情况,记录治疗期间两组心动过缓、低血压、谵妄等不良反应发生情况。结果与T0相比,两组T1、T2、T3时GCS评分均升高,且观察组升高更明显(P均0.05)。结论亚低温疗法联合右美托咪定静脉注射用于sTBI患者去骨瓣减压术后可降低患者ICP、改善脑血流和脑氧代谢,降低血清GFAP水平,且安全性较好。

Yeya Lake Wetlands are the largest site for wintering birds in Beijing, where common cranes(Grus grus)winters every year. The land cover of the wetlands has undergone distinct changes from 2006 to 2009 as a result of human activities. In 2006, a survey of the presence/absence of the birds was completed using a line-transect method.A predictive model of habitat suitability was derived by using logistic regression and geographic information ***, this habitat suitability model was applied in 2009 under the land use change to test the effectiveness of the model and compare the habitat suitability between 2 years. The negative associations between Grus grus presence and increasing elevation, distances to grassland, to farmland, to bush, and to road suggested a preference for low lying areas in close proximity to food and cover. While the positive associations with distances to buildings and to water suggested a preference for low disturbance areas. The areas of suitable habitats increased from 2006 to 2009, and the spatial model was effective in both years. Habitat preference of Grus grus varied in land use types, therefore habitat suitability dynamics might possibly relate to land use change and thereby be predictable through a geographic information system approach. Although the obtained model had a good fit in both years, it was suspected that if frequent human activities continued, the number of Grus grus might decrease or disappear in this area. According to the field survey, the spacious water area was essential for wintering birds and the risks from loss of lake water and unfavorable crop practices might dramatically change the quality of each type of land use.

With the impetus of the WTO and the further opening of China＇s international service trade in education, this paper is based on the background of China＇s national strategy ＂one belt ＆ one road＂, analyzing Guangzhou higher education, its internationalization driving force and popularization value, ranging from the perspectives of higher education resources excess, the domestic university funding cuts, and the transnational education services output in developed countries to alleviate its school funds shortage to further introduction of foreign high-quality educational resources due to not fully meeting the requirements of domestic demand in developing and less developed countries, with expectation to promote the development of education internationalization healthily and orderly.

Acupuncture is an ancient therapeutic method based on the theory of Chinese medicine(CM). Traditional acupuncture has many limitations;it is subjective and relies more on the experience of an acupuncturist, and the efficacy is sometimes irreproducible. In contrast, electroacupuncture(EA) has special characteristics in terms of objectivity and stability, thereby gaining considerable attention. Parameter setting plays a crucial role in EA practice. The current paper summarizes the current situation and limitations of parameter setting in EA practice. Objectification is the tendency and future of CM as well as EA. With the development of computerized technologies, such as wearable sensors, vast data, and artificial intelligence, CM syndromes can be successfully objectified. We propose the development of a novel self-feedback-adjust EA system, which may improve the parameter setting in EA and be beneficial to both the patients and clinicians.
