Abstract: Aim:To explore what is the relationship of the types of post-stroke aphasia with sex, age andstroke types.Methods:Retrospective analysis was administrated on data of 421 patients with acutestroke. Western battery aphasia was used to measure aphasiac type and aphasia quotient (AQ)score. The patients were divided into three age groups: young, middle-aged and elderly. The stroketypes were classified into cerebral infraction (CI) and intracerebral hemorrhage (ICH). Results: All subjects were right-handed, which males and females accounted for 69.60% and 30.40%, respectively. There were 116 cases of Broca’s aphasia (85 males), 35 cases of Wernicke’s aphasia (20 males),15 cases of conductive aphasia (10 males), 63 cases of transcortical motor aphasia (50 males), 11 cases of transcortical sensory aphasia (8 males), 27 cases of transcortical combined aphasia (13 males), 73 cases of anomic aphasia (47 males) and 81 cases of global aphasia (60 males). Male patients (69.60%) have a significantly higher morbidity of aphasia than that of females (30.40%) after stroke (χ2

World Journal of Neuroscience (WJNS) , 2015, DOI: 10.4236/wjns.2015.51007
Abstract: Alzheimer’s disease (AD) is a progressive, neurodegenerative disorder characterized by impairments in multiple cognitive domains and it is hard to diagnose in early stage because it’s not easy to recognize and develop slowly. In this study, we try to evaluate the difference of white matter between AD and health volunteers using diffusion tensor imaging (DTI) and try to provide some evidence for diagnose AD in early stage. Twelve elderly Chinese patients with AD and twelve healthy volunteers were recruited and underwent DTI. The raw diffusion data were dealt with the toolkit of FSL image post-processing. Fractional anisotrogy (FA) data were then carried out by using tract-based spatial statistics (TBSS). The result showed that the FA of cingulum, hippocampus, corticospinal tract, and inferior fronto-occipital fasciculus significantly reduced in AD patients than that of volunteers. This indicated that the integrity of white matter tracts in these regions with AD was disturbed. On the other hand, the FA of other encephalic regions had no discrepancy compared with that of healthy volunteers. FA values were found reduced significantly in AD patients, especially in the posterior of the brain. These findings may provide image methods to diagnose patients with early stage of AD.

Jingfan Tang,Qin Zhu,Ming Jiang
Information Technology Journal , 2013,
Abstract: Nowadays software applications are increasingly becoming large in scale and complexity, thus, Graphical User Interface (GUI) testing plays a formal important role in ensuring the correctness and reliability of software applications. A variety of approaches in the area of GUI testing have emerged in recent years. One notable trend is Model-Based Testing (MBT) which creates an abstract test model that simulates the anticipated behavior of the System Under Testing (SUT) by using some software generated tools to generate model tests. This study highlights the designing as well as the presentation of a new automation testing framework for silverlight applications with particular focuses upon the integration of the Spec Explorer based MBT with a free web framework called WebAii. Both of the tools are available as open source. Spec Explorer can be used to generate the test cases automatically, while WebAii is used to simulate human action and operation processes to complete the test execution in an automated way.

Jingfan Tang,Ming Jiang,Qin Zhu
Information Technology Journal , 2012,
Abstract: Software Process Assessment (SPA) was conducted prior to Software Process Improvement (SPI) activities to identify the process areas to be improved. The process assessment methods such as ISO/IEC 15504-2 and SCAMPI were available to all enterprises. But they were difficult for most of small organization because of the complexity and the consequent large investment in terms of time and resources. In order to conduct the SPA activities with few efforts in the small organization effectively, this study presented a quantitative assessment model. It was an efficient approach to evaluate the quality of the process execution in the projects for improvement of the organizations maturity. The project activities and deliverables were identified as organizational standard assessment items which could be tailored for each specific project. The weight was assigned to the tailored assessment items and the corresponding review activities according to importance and priority. Through an effective quantitative approach on the milestone-driven assessment, the compliance score could be obtained based on the characterization of the assessment results from document inspection and interview session. The initial practices results showed that the presented lightweight assessment model was indeed suitable for small organization to support the process assessment and improvement activities.

Physics , 2015,
Abstract: The KM2A(one kilometer square extensive air shower array) is the largest detector array in the LHAA- SO(Large High Altitude Air Shower Observatory) project. The KM2A consists of 5635 EDs(Electromagnetic particle Detectors) and 1221 MDs(Muon Detectors). The EDs are distributed and exposed in the wild. Two channels, Anode and Dynode, are employed for the PMT(photomultiplier tube) signal readout. The readout electronics proposed in this paper aims at the accurate charge and arrival time measurement of the PMT signals, which cover a large amplitude range from 20P.E(photoelectrons) to 2?x10^5P.E. By using the Trigger-less architecture, we digitize signals close to the PMTs. All digitized data is transmitted to DAQ(Data Acquisition) via the simplified WR(White Rabbit) protocol. Compared with traditional high energy experiments, high-precision of time measurement in such a large area and suppression of temperature effects in the wild become the key techniques. Experiments show that the design has fulfilled the requirements in this project.
Capacity Worth of Energy Storage System in Renewable Power Generation Plant  [PDF]
Jinbin Li, Yao Yao
Engineering (ENG) , 2013, DOI: 10.4236/eng.2013.59B001
Abstract: With the advance in renewable generation technologies, the cost of renewable energy becomes increasingly competitive when compared to fossil fuel-based generation resources. It is economically beneficial to integrate large amounts of renewable capacity in power systems. Unlike traditional generation facilities, however, using renewable resources for generation presents technical challenges in producing continuous power. In this report, an Energy Storage System (ESS) is integrated to smooth the variations in renewable power production and ensure the output power more controllable. Since it requires capital investment for the storage devices, it is important to obtain reasonable estimate of the storage capacities. This project is therefore formulated as an optimization problem in determining the two dominating factors of the capital cost for the ESS: the power capacity and the energy capacity. The objective is to make the renewable power more reliable and simultaneously maximize the economic benefits that can be obtained from the scheme. To make the results more convincing, analyses in this report start with wind generation, for wind has greater variability and unpredictability than other renewable sources. Selection of ESS type is narrowed down to battery energy storage system (BESS) in the scheme. However, the methods presented here are suitable for any type of energy storage methods and are also useful for intermittent renewable energy resources other than wind.

Surgical Science (SS) , 2018, DOI: 10.4236/ss.2018.98032
Abstract: Objective: To explore senile brucellosis spondylitis clinical features and diagnostic criteria, in order to improve the diagnosis rate and evaluate the clinical effects of treatment strategies. Methods: From January 2002 to August 2015, 62 patients with Brucella-associated spondylitis were treated with comprehensive diagnosis based on epidemiological history, clinical manifestations, imaging findings, laboratory tests, and local biopsy. The positive rate of red plate agglutination test (RBPT) was 45.1%, the positive rate of serum tube agglutination test (SAT) was 51.6%, and the positive rate of brucellosis anti-human immunoglobulin test (Coomb’s) was 100%. All patients underwent X-ray, CT and MRI examinations. The positive rate of blood culture in pathogenic examination was 16.1%, and the positive rate of bone marrow culture was 38.5%. The positive rate of inflammatory granuloma or abscess in the lesion sampling culture was 73.6%. All patients underwent standardized drug therapy and hyperbaric oxygen adjuvant therapy. Among them, 38 patients with neurological impairment were treated with one-stage debridement and posterior pedicle screw fixation on the basis of drug therapy. The paraspinal abscess and the diseased in-tervertebral space tissue were taken for pathological examination during the operation. One week, two weeks, one month, three months, six months and 12 months after treatment, the patients were evaluated and followed up at the monitoring sites. The evaluation indicators were pain scores, activity of daily living (ADL), imaging findings, and laboratory tests. The SPSS15.0 statistical package was used for analysis. Results: All patients were confirmed by the above-mentioned comprehensive examination after admission. 24 patients (38.71%) were treated with standard drug therapy (group A), no adverse drug reactions and abnormal liver and kidney function; the remaining 38 patients (61.29%) were combined with varying degrees of neurological impairment, and surgical treatment was performed after 2 to 4 weeks of drug therapy without improvement (group B). The pain scores showed that there was a statistically significant difference between the two groups at the same time point (P < 0.05). The B group was superior to the A group in both treatment time and pain relief. The blind test evaluation of imaging observation showed that in group B, except for the slow repair of the lesion area, the spine was stable without abscess, sequestrum and inflammatory granulomas, and the score area was stable at 4 -

Abstract: Edwardsiella bacteria are leading fish pathogens causing huge losses to aquaculture industries worldwide. E. tarda is a broad-host range pathogen that infects more than 20 species of fish and other animals including humans while E. ictaluri is host-adapted to channel catfish causing enteric septicemia of catfish (ESC). Thus, these two species consist of a useful comparative system for studying the intricacies of pathogen evolution. Here we present for the first time the phylogenomic comparisons of 8 genomes of E. tarda and E. ictaluri isolates. Genome-based phylogenetic analysis revealed that E. tarda could be separate into two kinds of genotypes (genotype I, EdwGI and genotype II, EdwGII) based on the sequence similarity. E. tarda strains of EdwGI were clustered together with the E. ictaluri lineage and showed low sequence conservation to E. tarda strains of EdwGII. Multilocus sequence analysis (MLSA) of 48 distinct Edwardsiella strains also supports the new taxonomic relationship of the lineages. We identified the type III and VI secretion systems (T3SS and T6SS) as well as iron scavenging related genes that fulfilled the criteria of a key evolutionary factor likely facilitating the virulence evolution and adaptation to a broad range of hosts in EdwGI E. tarda. The surface structure-related genes may underlie the adaptive evolution of E. ictaluri in the host specification processes. Virulence and competition assays of the null mutants of the representative genes experimentally confirmed their contributive roles in the evolution/niche adaptive processes. We also reconstructed the hypothetical evolutionary pathway to highlight the virulence evolution and niche adaptation mechanisms of Edwardsiella. This study may facilitate the development of diagnostics, vaccines, and therapeutics for this under-studied pathogen.
