In this paper,the main aim is the performances modelling from the electrical and thermal point of view of a concentrating photovoltaic and thermal (CPV/T)system in order to evaluate the primary energy and economic savings respect to a traditional system,when the same energy loads are satisfied.This study is realized by both varying the CPV/T system configuration and considering two different users.In particular,the point-focus (PF),and linear focus (LF)configurations of the CPV/T system are considered in order to match the residential user and hotel energy loads.The CPV/T system is sized adopting as input data:the Direct Normal Irradiance (DN1)modelled by an artificial neural network and the users'energy demands.In these hypotheses,the performances of the PF and LF systems are evaluated and then compared for the two users located in Southern Italy,in terms of electrical and thermal energy production,cells number,space occupied,energy and economic savings and CO2 emissions avoided.Finally,the PF system shows a lower simple pay-back and a higher primary energy saving,while the space occupied by a LF system results to be lower respect to the PF configuration. 展开更多

A cloud method for generating percentile engineering demand parameter versus intensity measure(EDP-IM) curves of a structure subjected to a set of synthetic ground motions is presented. To this end, an ensemble of synthetic ground motions based on available real ones is generated. This is done by using attenuation relationships, duration and suitable Gutenberg-Richter relations attributed to the considered seismic hazard at a given site by estimating a suitable distribution of magnitude and site to source distance. The study aims to clarify the significance of the duration and frequency content on the seismic performance of structures, which were not considered in developing percentile incremental dynamic analysis(IDA) curves. The collapse probabilities of two steel moment-resisting frames with different ductility levels generated by IDA and the proposed cloud method are compared at different intensity levels. When compared with conventional IDA, the suggested cloud analysis(SCA) methodology with the same run number of dynamic analyses was able to develop response hazard curves that were more consistent with site-specific seismic hazards. Eliminating the need to find many real records by generating synthetic records consistent with site-specific seismic hazards from a few available recorded ground motions is another advantage of using this scheme over the IDA method. 展开更多

Objective: To decipher the possible mechanisms of Sinomenium Acutum(SA) in treating diseases by a bioinformatics method. Methods: SA ingredients were searched according to Chinese Pharmacopoeia, Chinese Medicine Dictionary and Traditional Chinese Medicines Database(TCMD). Active compounds and target proteins of SA were acquired through the Pubchem platform. Pathway, network and function analyses of SA were performed with ingenuity pathway analysis(IPA), a bioinformatics analysis platform. Disease, biofunction-target networks were established with Cytoscape. Results: Eighteen ingredients from SA were obtained. Seven active ingredients with 31 active target proteins were acquired according to PubChem Bioassay test. By IPA analysis, 277 canonical pathways belonging to 17 function categories were collected, 23 kinds of diseases, 21 categories bio-functions were obtained. Based on P value, calculated by IPA, the top 5 significant pathway of SA targets include phosphatidylinositol 3 kinase/Akt(PI3 K/Akt) signaling, prostate cancer signaling, macrophage migration inhibitory factor(MIF) regulation of innate immunity, Guanosine-binding protein coupled receptor(GPCR) signaling, and ataxia telangiectasia mutated protein(ATM) signaling. Disease and bio-function network analysis indicated that mitogen activated protein kinase 1(MAPK1), MAPK3, p65 nuclear factor κB(RELA), nuclear factor of κB inhibitor alpha(NFκBIA), interleukin 1β(IL-1β), prostaglandin G/H synthase 2(PTGS2) and tumor protein 53(TP53) were the critical targets in various diseases treated by SA. Conclusions: In the different view of target, pathway, disease and bio-function, inflammation was found to be a central theme in many chronic conditions. SA could be used not only as an anti-inflammatory agent, but also for the treatment of cancers, neurological diseases, psychological disorders and metabolic diseases. 展开更多

Nowadays, DNA-mediated metal nanomaterials have received more and more attention due to their distinctive properties of easy synthesis, high stability and good biocompatibility. As a kind of efficient template to mediate the precise synthesis of metal nanomaterials, DNA can not only increase their recognition and biocompatibility, but also precisely control their morphology, structure and further analytical performance. DNA-mediated metal nanomaterials as ultrasensitive and selective probes have unique advantages for in situ rapid analysis of targets in complex samples. Herein, we reviewed the recent progress on synthesis strategies, morphologies, specific properties of DNA-mediated metal nanomaterials including nanoparticles and nanoclusters. Moreover, the applications of DNA-mediated metal nanomaterials to environmental and biological analysis were also summarized. Finally, the developing prospect of DNA-mediated metal nanomaterials in analytical chemistry was discussed and proposed. 展开更多

This work describes the seismic vulnerability assessment of a railway masonry arch bridge.Its conservation state is initially investigated by means of a thorough field and laboratory test campaign, comprising destructive and non-destructive tests. Two different methods are used to evaluate the bridge seismic vulnerability. The first method adopts a deterministic approach and corresponds to a single non-linear static analysis, performed as described in the Eurocodes. The second method employs a probabilistic approach and considers the variability of the involved mechanical parameters(structure geometry and properties of the building materials) and seismic parameters(intensity of the action and site conditions). This method associates the probabilistic values of ground acceleration exceedance to the estimated seismic vulnerability. This is shown by means of fragility curves, which allow to take into consideration the uncertainty of the various components involved in the definition of the seismic vulnerability and display the seismic damage scenarios. Currently no code requires to perform this calculation procedure. In addition,this work compares the values of masonry mechanical properties specified in the Eurocodes with those obtained in an extensive investigation campaign involving more than one hundred masonry bridges. Compressive strength and longitudinal elasticity modulus are the relevant mechanical parameters investigated. The outcomes of this research can contribute to the development of a more efficient maintenance system of the masonry bridges belonging to the railway network. This has an important role when it comes to establishing the priority order of assets intervention. 展开更多

Long non-coding RNAs(lncRNAs)play a key role in craniocerebral disease,although their expression profiles in human traumatic brain injury are still unclear.In this regard,in this study,we examined brain injury tissue from three patients of the 101st Hospital of the People’s Liberation Army,China(specifically,a 36-year-old male,a 52-year-old female,and a 49-year-old female),who were diagnosed with traumatic brain injury and underwent brain contusion removal surgery.Tissue surrounding the brain contusion in the three patients was used as control tissue to observe expression characteristics of lncRNAs and mRNAs in human traumatic brain injury tissue.Volcano plot filtering identified 99 lncRNAs and 63 mRNAs differentially expressed in frontotemporal tissue of the two groups(P<0.05,fold change>1.2).Microarray analysis showed that 43 lncRNAs were up-regulated and 56 lncRNAs were down-regulated.Meanwhile,59 mRNAs were up-regulated and 4 mRNAs were down-regulated.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)analyses revealed 27 signaling pathways associated with target genes and,in particular,legionellosis and influenza A signaling pathways.Subsequently,a lncRNA-gene network was generated,which showed an absolute correlation coefficient value>0.99 for 12 lncRNA-mRNA pairs.Finally,quantitative real-time polymerase chain reaction confirmed different expression of the five most up-regulated mRNAs within the two groups,which was consistent with the microarray results.In summary,our results show that expression profiles of mRNAs and lncRNAs are significantly different between human traumatic brain injury tissue and surrounding tissue,providing novel insight regarding lncRNAs’involvement in human traumatic brain injury.All participants provided informed consent.This research was registered in the Chinese Clinical Trial Registry(registration number:ChiCTR-TCC-13004002)and the protocol version number is 1.0. 展开更多

Laser-induced breakdown spectroscopy (LIBS) is a sensitive optical technique that is capable of rapid multi-elemental analysis. The development of this technique for elemental analysis of pharmaceutical products may eventually revolutionize the field of human health. Under normal circumstances, the elemental analysis of pharmaceutical products based on chemical methods is time-consuming and complicated. In this investigation, the principal aim is to develop an LIBS-based methodology for elemental analysis of pharmaceutical products. This LIBS technique was utilized for qualitative as well as quantitative analysis of the elements present in Ca-based tablets. All the elements present in the tablets were detected and their percentage compositions were verified in a single shot, using the proposed instrument. These elements (e.g., Ca, Mg, Fe, Zn, and others) were identified by the wavelengths of their spectral lines, which were verified using the NIST database. The approximate amount of each element was determined based on their observed peaks and the result was in exact agreement with the content specification. The determination of the composition of prescription drug for patients is highly important in numerous circumstances. For example, the exploitation of LIBS may facilitate elemental decomposition of medicines to determine the accuracy of the stated composition information. Moreover, the approach can provide element-specific, meaningful, and accurate information related to pharmaceutical products. 展开更多

A passive compliant non-cooperative target capture mechanism is designed to maintain the non-cooperative target on-orbit. When the relative position between capture mechanism and satellite is confirmed,a pair of four-bar linkages lock the docking ring,which is used for connecting the satellite and the rocket. The mathematical model of capture mechanism and capture space is built by the Denavit-Hartenberg(D-H)method,and the torque of each joint is analyzed by the Lagrange dynamic equation. Besides,the capture condition and the torque of every joint under different capture conditions are analyzed by simulation in MSC. Adams. The results indicate that the mechanism can capture the non-cooperative target satellite in a wide range. During the process of capture,the passive compliant mechanism at the bottom can increase capture space,thereby reducing the difficulty and enhance stability of the capture. 展开更多
