Energies , 2013, DOI: 10.3390/en6041887
Abstract: Electric load forecasting is an important issue for a power utility, associated with the management of daily operations such as energy transfer scheduling, unit commitment, and load dispatch. Inspired by strong non-linear learning capability of support vector regression (SVR), this paper presents a SVR model hybridized with the empirical mode decomposition (EMD) method and auto regression (AR) for electric load forecasting. The electric load data of the New South Wales (Australia) market are employed for comparing the forecasting performances of different forecasting models. The results confirm the validity of the idea that the proposed model can simultaneously provide forecasting with good accuracy and interpretability.

BMC Immunology , 2010, DOI: 10.1186/1471-2172-11-9
Abstract: Four kinds of pathogens Bacillus thuringiensis, Klebsiella pneumoniae, Candida albicans, and Autographa californica multiple nucleocapsid nucleopolyhedrovirus harbored green fluorescence protein and polyhedron (AcMNPV-GFP) were used to challenge the insect. The cellular and humoral immune responses to the pathogens were analyzed in the challenged H. armigera. The results show that in the five kinds of haemocytes, only granulocytes phagocytized the Gram-negative and Gram-positive bacteria and fungi. All haemocytes can be infected by AcMNPV. Fourteen immune-related genes including pattern recognition receptors (PRRs) such as peptidoglycan recognition proteins (HaPGRP and HaPGRP C) and Gram-Negative Bacteria-Binding Protein (HaGNBP), and antimicrobial peptides (AMPs) such as cecropin-1, 2 and 3 (HaCec-1, 2 and 3), lysozyme (HaLys), attacin (HaAtt), gallerimycin-like (HaGall), gloverin-like (HaGlo), moricin-like (HaMor), cobatoxin-like (HaCob), galiomicin-like (HaGali), and immune inducible protein (HaIip) appeared in different expression profiles to different pathogen infections. The transcripts of 13 immune related genes (except HaPGRPC) are obviously up-regulated by Gram-positive bacteria. HaCec-1 and 3, HaMor, HaAtt, HaLys, HaIip, HaPGRP and HaGNBP are greatly up-regulated after fungal infection. HaGNBP, HaCec-2, HaGall, HaGlo, HaMor, HaCob, HaGali obviously increased in Gram-negative bacterial infection. Only five genes, HaGNBP, HaCec-1, HaGali, HaGlo, and HaLys, are weakly up-regulated after viral infection. The AMP transcripts had higher expression levels than the PRR transcripts after the microbial challenge.These data suggest that the granulocytes are the major phagocytes in H. armigera. All haemocytes can be infected by AcMNPV. The transcripts of 14 immune related genes have different expression patterns in H. armigera infected by different pathogens, which means that the immune-related genes may have different functions against various kinds of pathogens.The

Abstract: Objective To investigate the characteristics of ectopic automaticity and cation current (If) of cardiac myocytes from pulmonary vein sleeves (PVs) in canines with atrial fibrillation. Methods The canines (8–10 years old) were subjected to long-term, rapid atrial pacing (RAP) for 10 weeks, which induced the atrial fibrillation model. Disassociation of PVs of canines yielded single cardiac myocytes from a Landengorff column. Action potential, If and hyperpolarisation activated cyclic nucleotide-gated (HCN) currents were measured with the patch-clamp technique. Results Compared with the control group, cardiac myocytes from the RAP canine PVs had spontaneous diastolic depolarization, shorter action potential duration, and larger If densities. In the group of RAP cells, the half maximal activation potential (V1/2) was found to be less negative ( 105.5 ± 5.2 mV) compared to control cells ( 87.3 ± 4.9 mV). Current densities of If were increased significantly by β-adrenergic receptor stimulation with isoproterenol and caused an acceleration of current activation. In contrast, If currents in the RAP were reduced by carvedilol, a selective beta-adrenergic receptor. Another important finding is that HCN4-based channels may make a significant contribution to If in PVs cells, but not HCN2. Meanwhile, HCN4 current significantly increases in canine PVs cardiac myocytes with RAP. Conclusions The spontaneous action potential and larger If current were observed in the PVs cardiac myocytes using RAP, which may contribute to more ectopic activity events to trigger and maintain atrial fibrillation.

老年心脏病学杂志(英文版) , 2010,
Abstract: Objectives This study aimed at investigating the cellular mechanism of isoproterenol (ISO) on delayed after depolarizations (DADs) and triggered activity (TA) of the noninfarcted myocardium in the myocardial infarcted rabbit model. Methods Rabbits with the left anterior descending coronary artery occlusion were prepared and recovered for 8 wk (healed myocardial infarction, HMI). Myocytes were isolated from regions of the noninfarcted left ventricular free wall. ISO was added to cellular surface by perfusion way. Action potentials and ion currents were recorded with whole-cell patch clamp. Results The results showed that treatment with ISO induced more DADs and TA events in HMI myocytes. Inward transient current (Iti) and ICa-L of myocytes treated with ISO were increased significantly compared with HMI cells, which contributed to DADs-related triggered arrhythmia. Conclusions The results suggested that more arrhythmia events of DADs and TA developed in myocytes with ISO treatment. The underlying mechanism was associated with the augment of Iti and calcium influxing.
Evolution of the Coronal Magnetic Configurations Including a Current-Carrying Flux Rope in Response to the Change in the Background Field

Abstract: We investigate equilibrium height of the flux rope, and its internal equilibrium in a realistic plasma environment by carrying out numerical simulations of the evolution of systems including a current-carrying flux rope. We find that the equilibrium height of the flux rope is approximately a power-law function of the relative strength of the background field. Our simulations indicate that the flux rope can escape more easily from a weaker background field. This further confirms the catastrophe in the magnetic configuration of interest can be triggered by decrease of strength of the background field. Our results show that it takes some time to reach internal equilibrium depending on the initial state of the flux rope. The plasma flow inside the flux rope due to the adjustment for the internal equilibrium of the flux rope remains small and does not last very long when the initial state of the flux rope commences from the stable branch of the theoretical equilibrium curve. This work also confirms the influence of the initial radius of flux rope on its evolution, the results indicate that the flux rope with larger initial radius erupts more easily. In addition, by using the realistic plasma environment and much higher resolution in our simulations, we notice some different characters compared to previous studies in Forbes (1990).

International Journal of Molecular Sciences , 2012, DOI: 10.3390/ijms130911063
Abstract: Aspergillosis remains to be a life-threatening complication in immunocompromised patients. However, Aspergillus infection can be observed in non-immunocompromised individuals in rare cases. We report a case of liver aspergilloma in a chronic aplastic anemia patient under relatively intact immune status. Therapeutic strategy for this rare condition was extensively discussed and caspofungin acetate single agent first-line therapy was applied after careful consideration. Encouraging clinical and radiologic improvements were achieved in response to the antifungal salvage. Our long-term follow-up study also revealed a favorable prognosis. Based on this experience, we suggest caspofungin acetate as first-line therapy for treatment plans of liver aspergilloma.

Abstract: For the disadvantages of bitmap font, such as large storage, the quality of zooming was hard to guarantee, this paper designed an approach for auto-generating curve contour character from bitmap. The main idea of the implementation was to extract the contour data of NüShu character, and then proposed an approach for detecting feature points based on maximum error, at last fitted the contour based on straight line and quadratic Bezier curves and stored the data of curves and generated the character of NüShu described by curves. The result shows that this method is very simple and reduces the storage space greatly. The generated curve contour is the same as the original font and it also can eliminate burrs caused by hand-writing. This method is also the basis of computer processing of NüShu characters.
