短期负荷预测在能源互联网的规划中既占重要组成部分,又是能源系统可靠高效运行的基础。在能源互联网中能源的短期负荷预测精度问题是人们重点关注问题。n-BEATS的深度神经结构未使用时序特别组成成分,仅使用一种基于后向和前向残差链路以及非常深的全连接层堆栈的深度神经架构。该结构具有可解释性、适用于广泛的目标域、并且训练速度快等优点。实验使用n-BEATS模型对历史负荷数据进行训练,然后对未来负荷进行短期负荷预测,取得了较高的预测精度。测得平均绝对百分比误差(eMAPE)为1.26%,平均绝对误差(eMAE)为84.238 kw,决定系数(R^(2))为0.9955,实验结果表明采用该方法的预测精度高于传统的预测方法,如在eMAPE方面相比TCn降低了0.61%。

The nyakong-Manyi Shear Zone(nMSZ) is a nE-SW elongated corridor found to the northwest of the Foumban-Bankim Shear Zone(FBSZ) along the Central Cameroon Shear Zone. Controversial chronology models has been proposed for the kinematic evolution of the sinistral and dextral shear phases in the Tikar Plain, thus in the FBSZ;early dextral and late sinistral shear phases for some authors and early sinistral and late dextral shear for others. Moreover, the nMSZ kinematic evolution implication on the mylonitization P-T-t path in the area seem to be problematic and the present paper aim is to clear enough those problems;since this shear zone is the main mylonitic corridor that registered the left and right lateral movement in this area. The nMSZ comprises amphibolites, protomylonites, strict sensus mylonites(garnet-kyanite-sillimanite mylonite and garnet-pyroxene mylonite), ultramylonites kyanite-sillimanite and garnet-kyanite-sillimanite gneiss. Field structures testify that the investigated area recorded three deformation phases:(i) the D1deformation phase which is marked by nW-SE to n-S trending S1metamorphic foliation with low to moderate dips(15°–45°) that was transposed during the D2phase, is responsible for a regional metamorphism whose mineral paragenesis is garnet-kyanite-sillimanite;(ii) the early sinistral nnE-SSW to nE-SW shear phase D2marked by S2metamorphic and mylonitic foliations;responsible for, L2stretching mineral lineation, F2fold axes and B2boudins structures;(iii) the late dextral nE-SW shear phase D3, characterized by F3folds, B3boudins and ductile dextral C3shear planes. Mineral paragenesis garnet + kyanite + sillimanite and microstructures within gneiss testify that this rock underwent high grade regional metamorphism whose peak conditions are estimated at 11.5–13.5 kbar/850–900 ℃. After the peak of metamorphism gneiss was overprinted by high grade pressure mylonitization during the early sinistral and late dextral shear deformations. Microstructura

The Fomopea granitic pluton is emplaced in gnessic and amphibolitic basement. These gneissic and amphibolitic basement rocks are represented in the pluton＇s body as sub-rounded, elongated or stretched xenoliths. Amphibolitic xenoliths display testimonies of two main tectonic events namely：（i） El flattening deformation event characterized by a nW-SE to E-W foliation with a best pole at 246/57 and a mineral stretched lineation with a best line at 293/47; and （ii） E2 compressive event typified by （1） n-S to nnE-SSW steeply dipping foliation; （2） S-type flexion-fold indicating a sinistral shear movement. These amphibolite rocks indicate a magnetic susceptibility magnitude （Km） range from 418 ~SI to 90092 IISI for 87% of the stations showing a ferromagnetic behavior. K-T curves reveal the presence of Ti-poor magnetite as susceptibility mineral carrier. Magnetic foliation and lineation suggest that the n-S strike direction observed in the Bamendou amphibolite is, as pointed out elsewhere in the Central African Fold Belt, of paramount importance in the tectonic evaluation of the Fomopea area, since it has most likely acted as major deformation phase in the second tectonic event in the belt.

Human Myoblast Genome Therapy (HMGT) is a platform technology of cell transplantation, nuclear transfer, and tissue engineering. Unlike stem cells, myoblasts are differentiated, immature cells destined to become muscles. Myoblasts cultured from satellite cells of adult muscle biopsies survive, develop, and function to revitalize degenerative muscles upon transplantation. Injection injury activates regeneration of host myofibers that fuse with the engrafted myoblasts, sharing their nuclei in a common gene pool of the syncytium. Thus, through nuclear transfer and complementation, the normal human genome can be transferred into muscles of patients with genetic disorders to achieve phenotype repair or disease prevention. Myoblasts are safe and efficient gene transfer vehicles endogenous to muscles that constitute 50% of body weight. Results of over 280 HMGT procedures on Duchenne Muscular Dystrophy (DMD) subjects in the past 15 years demonstrated absolute safety. Myoblast-injected DMD muscles showed improved histology. Strength increase at 18 months post-operatively averaged 123%. In another application of HMGT on ischemic cardiomyopathy, the first human myoblast transfer into porcine myocardium revealed that it was safe and effective. Clinical trials on approximately 220 severe cardiomyopathy patients in 15 countries showed a nted on the epicardial surface during coronory artery bypass graft, or injected on the endomyocardial surface percutaneously through guiding catheters. Significant increases in left ventricular ejection fraction, wall thickness, and wall motion have been reported, with reduction in perfusion defective areas, angina, and shortness of breath. As a new modality of treatment for disease in the skeletal muscle or myocardium, HMGT emerged as safe and effective. Large randomized multi-center trials are under way to confirm these preliminary results. The future of HMGT is bright and exciting.

Objectives This study investigated the efficacy of human skeletal myoblasts (SkM) mediated either human vascular endothelial growth factor-165 (hVEGF165) or angiopoietin-1 (Ang-1) on vascular development and myocardial regional perfusion. Methods A porcine heart model of chronic infarction was created in 28 female swine by coronary artery ligation. The animals were randomized into: (1) group-1, DMEM injected (n=6), (2) group-2, Ad-null transduced SkM transplanted (n=6), (3) group-3, Ad-hVEGF165 transduced SkM transplanted (n=8), and (4) group-4, Ad-Ang-1 transduced SkM (n=8). Three weeks later, 5 ml DMEM containing 3×108 SkM carrying exogenous genes were intramyocardially injected into 20 sites in left ventricle in groups-2, -3 and -4. Animals in group-1 were injected 5 ml DMEM without cells. Animals were kept on 5 mg/kg cyclosporine per day for 6 weeks. Regional blood flow was measured using fluorescent microspheres. The heart was explanted at 2, 6 and 12 weeks after transplantation for histological studies. Results Histological examination showed survival of lac-z expressing myoblasts in host tissue. Capillary density based on Von Willebrand factor-VIII (vWF-VIII) at low power field (×100) was 57.13±11.85 in group-3 at 6 weeks and declined to 32.1±5.21 at 12 weeks, while it was 39.9±10.26 at 6 weeks and increased to 45.14±6.54 at 12 weeks in group-4. The mature blood vessel index was highest in group- 4 at 6 and 12 weeks after transplantation. The regional blood flow in the center and peri-infarct area was significantly increased in animals of groups-3 and -4. Conclusions SkM carrying either hVEGF165 or Ang-1 induced neovascularization with increased blood flow. Ang-1 overexpression resulted in mature and stable blood vessel formation and may be a more potent arteriogenic inducer for neovascularization.
