Application of cluster analysis and grey related degree to affecting factors analysis of construction accident

Construction is a high-risk industry,and the safety situation has been the concern of the community.In allusion to the status quo of the difficultly controlled construction supervision and the frequently occurred construction accidents,the data of high fall construction accidents during 1997-2006 were classified into ten kinds of affecting factors through splitting,merging and removing;then these affecting factors of construction accident mentioned above were incorporated into three kinds of affecting factors which included "man—management—matter" through the cluster analysis.And finally the grey related degree analysis was applied to rank the grey related degree of various affecting factors,in order to find out the weak point in the course of construction and to work out microcosmic supervisory measures and preventive measures for the safety of construction on site
Acupuncture enhances brain function in patients with mild cognitive impairment: evidence from a functional-near infrared spectroscopy study

Mild cognitive impairment (MCI) is a precursor to Alzheimer’s disease. It is imperative to develop a proper treatment for this neurological disease in the aging society. This observational study investigated the effects of acupuncture therapy on MCI patients. Eleven healthy individuals and eleven MCI patients were recruited for this study. Oxy- and deoxy-hemoglobin signals in the prefrontal cortex during working-memory tasks were monitored using functional near-infrared spectroscopy. Before acupuncture treatment, working-memory experiments were conducted for healthy control (HC) and MCI groups (MCI-0), followed by 24 sessions of acupuncture for the MCI group. The acupuncture sessions were initially carried out for 6 weeks (two sessions per week), after which experiments were performed again on the MCI group (MCI-1). This was followed by another set of acupuncture sessions that also lasted for 6 weeks, after which the experiments were repeated on the MCI group (MCI-2). Statistical analyses of the signals and classifications based on activation maps as well as temporal features were performed. The highest classification accuracies obtained using binary connectivity maps were 85.7% HC vs. MCI-0, 69.5% HC vs. MCI-1, and 61.69% HC vs. MCI-2. The classification accuracies using the temporal features mean from 5 seconds to 28 seconds and maximum (i.e, max(5:28 seconds)) values were 60.6% HC vs. MCI-0, 56.9% HC vs. MCI-1, and 56.4% HC vs. MCI-2. The results reveal that there was a change in the temporal characteristics of the hemodynamic response of MCI patients due to acupuncture. This was reflected by a reduction in the classification accuracy after the therapy, indicating that the patients’ brain responses improved and became comparable to those of healthy subjects. A similar trend was reflected in the classification using the image feature. These results indicate that acupuncture can be used for the treatment of MCI patients.
Assessment of podoplanin lymphatic vessel density in oral epithelial dysplasia

Background: Oral squamous cell carcinoma (OSCC) can be preceded by the appearance of lesions which have the potential to develop into cancer. Recently, it was suggested that the tumor-associated lymphatic vessels formation plays an active role in tumor progression and metastasis of several human malignancies including OSCC. There is the view that, in an individual lesion, the more severe the dysplasia, the greater the likelihood is of progression to malignancy. Aim: This study is aimed to investigate podoplanin (PDPN) immunoexpression in lymphatic vessels of oral epithelial dysplasia (OED) and to assess the lymphatic vessel density (LVD) in histologic grades of OED. Materials and Methods: The study group comprised thirty histopathologically diagnosed cases of OED with various grades of differentiation and thirty cases of clinically normal oral mucosa. After immunohistochemical staining, cases of OED were immunohistochemically analyzed quantitatively for PDPN (D2-40) LVD. Statistical Analysis: The statistical analysis was done using Kruskal Wallis analysis of variance; pair-wise Tukey's post hoc test was applied to evaluate the significant differences among the mean values in different groups. Results with “P < 0.05” were considered to be statistically significant at 95% of confidence level. Results: PDPN LVD scores increased with increasing grades of dysplasia. Pair-wise comparisons of the PDPN LVD scores and the histopathologic grades of OED were found to be statistically significant (P < 0.05). Conclusions: Increase in PDPN LVD in OED represents a promising tool for more wide spread studies of tumor lymphangiogenesis and its role in progression of dysplastic lesion to human cancer.
Effect of two calcium-silicate sealers and a resin sealer on collagen matrix integrity of root dentin after different treatments. An in vitro and in vivo study

Introduction: This research aimed to examine and compare the effect of two calcium silicate sealers with AH plus resin sealer on collagen extraction and surface collagen degradation of dog's root dentin, using different irrigants. Materials and Methods: In vitro part; 180 standardized root dentin cylinders obtained from dog's incisors were randomly allocated into three groups (n = 60) according to the final irrigant used; Group A: 17% Ethylenediaminetetraacetic acid, Group B: 2.5% NaOCl, Group C: 0.9% saline. Each group was classified into 4 subgroups (n = 15) according to the type of sealer used for obturation; subgroup 1: BioRoot RCS, subgroup 2: Total Fill BC, subgroup 3: AH Plus sealer, and subgroup 4: Unfilled (control). After preparation, irrigation, obturation, and aging in a storage medium; hydroxyproline (HYP) released in the medium was determined after 1 day, 1 and 3 months using spectrophotometer. In vivo part, sixty incisors of five dogs were randomly allocated as in the vitro part into three groups and four subgroups in accordance to the type of irrigation and sealer used. After 3 months of preparation, irrigation, and obturation, dogs were euthanized and teeth were extracted for the assessment of surface collagen degradation using scanning electron microscope. HYP released was analyzed using repeated-measures analysis of variance and post hoc of Bonferroni. Surface collagen degradation was analyzed using Kruskal–Wallis test and Dunn's test. Results: BioRoot RCS and TotalFill BC showed a significant higher (P < 0.001) HYP release and surface collagen degradation than AH plus sealer and control with all irrigants. Conclusions: Calcium silicate sealers significantly affected the collagen microstructure of dentin surface. AH Plus resin sealer has no effect on collagen dissolution or microstructure.
Circuit Oriented Topology Analysis of Medium-Voltage Distribution Network

As there are lots of lines and equipment components in medium-voltage distribution network,but less connection of equipments among various lines,the object "circuit" is defined in this paper as "collection of conducting equipments including lines(overhead lines,cables) and related equipment components",thus the distribution network consists of different circuits that are connected with each other through interconnection switches,and each circuit is divided into several circuit-sections,and connected to the bus of substation via its outlet switches.The circuit oriented topology analysis method in this paper is as follows: to analyze the circuits first,then the connection lines based on interconnection switches,and finally the whole network based on the on-off states of substation outlet switches.The proposed method has high speed as it devides the network into circuits,and thus the search scope of analysis becomes smaller.
Robust adaptive controller design for block BTT missile model

Firstly,BTT block control model,which was suitable for backstepping design,was given for nonlinear model of BTT missile.Making full use of the characteristic of the system and combining block control principle,backstepping technique,robust control and adaptive control method,a robust adaptive controller design method was proposed.Uncertainties in every sub-block were allowed. "Computer explosion" is reduced by introducing nonlinear tracking differentiator and the possible singularity of controller is avoided when the control matrix is unknown.It is proved that the state tracking errors and parameter errors converge to the neighborhoods of the origin exponentially.Finally,the given simulation results show the effectiveness of the proposed method.
N-ary Relation Extraction for Joint T-Box and A-Box Knowledge Base Augmentation

The Web has evolved into a huge mine of knowledge carved in different forms, the predominant one still being the free-text document. This motivates the need for Intelligent Web-reading Agents: hypothetically, they would skim through disparate Web sources corpora and generate meaningful structured assertions to fuel Knowledge Bases (KBs). Ultimately, comprehensive KBs, like Wikidata and DBpedia, play a fundamental role to cope with the issue of information overload. On account of such vision, this paper depicts the F ACT E XTRACTOR , a complete Natural Language Processing (NLP) pipeline which reads an input textual corpus and produces machine-readable statements. Each statement is supplied with a conﬁdence score and undergoes a disambiguation step via entity linking, thus allowing the assignment of KB-compliant URIs. The system implements four research contributions: it (1) executes N-ary relation extraction by applying the Frame Semantics linguistic theory, as opposed to binary techniques; it (2) jointly populates both the T-Box and the A-Box of the target KB; it (3) relies on a lightweight NLP machinery, namely part-of-speech tagging only; it (4) enables a completely supervised yet reasonably priced machine learning environment through a crowdsourcing strategy. We assess our approach by setting the target KB to DBpedia and by considering a use case of 52 , 000 Italian Wikipedia soccer player articles. Out of those, we yield a dataset of more than 213 , 000 triples with a 78 . 5% F 1 . We corroborate the evaluation via (i) a performance comparison with a baseline system, as well as (ii) an analysis of the T-Box and A-Box augmentation capabilities. The outcomes are incorporated into the Italian DBpedia chapter, can be queried through its SPARQL endpoint, and/or downloaded as standalone data dumps. The codebase is released as free software and is publicly available in the DBpedia Association repository.
The phenology of the emergence of brassica pod midge (Dasineura brassicae Winn.) and its infestation of winter oil-seed rape (Brasica napus L.)

Summary The phenology of the emergence of brassica pod midge from overwintering sites and its subsequent infestation of winter oil-seed rape crops on a farm in southern England was studied over 3 years. Two generations occurred each year. The first generation of adults emerged from mid-May or early June until early July from overwintering cocoons in soil at sites where oil-seed rape had been grown in the previous year or years. Many females and a few males migrated to flowering winter rape crops where eggs were laid in the pods. Mature larvae dropped daily from the pods from early or mid-June until late July or early August, and formed cocoons in the soil. The second generation of adults emerged from late June until mid-July or early August to lay further eggs in the crop. Larvae from these eggs dropped to the soil to diapause within cocoons for up to 3 years.
Age, Growth, Reproduction and Fecundity of the Sharpsnout Seabream (Diplodus puntazzo Walbaum, 1792) in the Black Sea Region

In this study, the Sharpsnout Seabream (Diplodus puntazzo) population parameters (age, sex composition, length-weight relationship (LWR), age-length relationship, growth parameters, condition factor, gonadosomatic index, reproductive) of the sharpsnout seabream (Diplodus puntazzo) in the southern Black Sea Region have been investigated. In the study carried out between April 2018 and March 2019, 276 sharpsnout seabream were sampled and the average length and weight were calculated as 30.0 cm and 463.9 g, respectively. Male and female ratio was determined as 1:1.32 (P>0.05). Age of fish varied between 0-9 years. The von Bertalanffy growth parameters were L∞=48.1 cm, k=0.2656 year-1 and t0=-1.6587 year for all individuals. The LWR was found as W=0.0399 L2.7212 for all individuals. Total mortality rate (Z=0.560), natural mortality rate (M=0.501) and fishing mortality rate (F=0.059), growth performance index (φ'=2.73) and condition factor value (K=1.55) were calculated. The maximum GSI value was 6.83 in September. Mean relative fecundity was calculated as 14695.4 eggs / 1g. The mean egg diameter was calculated as 486.83µm. This study is very important in terms of being the first study on this species in the Black Sea and will provide a source for future studies.
A NOVEL TECHNIQUE FOR ANALYSIS & MODELLING OF NON- UNIFORM TRANSMISSION LINE IN MATLAB SIMULINK

A transmission line having its length less than 80 km is considered as a short transmission line. In short transmission line capacitance is neglected because of small leakage current and other parameters (resistance and inductance) are lumped in the transmission line. This thesis has two part of simulation one contains the perturbation theory and second is simulink model of short distance transmission line modeling. It consider the nonuniform transmission line. For obtaining ̫result we consider the resistance, inductance and capacitance per unit length (R(z),L(z), C(z), G(z)) are assumed that they are slowly variable parameter along the distance (Z), the distance along the line from the source end. In perturbation theory it is applied to the solution of inhomogeneous transmission line equations. It considers the distributed parameters of the line. In the simulink model the short transmission line has been simulated on which perturbation theory can be performed. As per this analysis this thesis found the transmission line linearity analysis of signal at sending end and receiving end that resemble that the output graph of frequency becomes linear just after the simulation starts. It has clear that the transmission line has stable output and very less distortion. Keyword: Perturbation theory, Simulink, Short Transmission Line, Matlab.

Digitalisation and the foundational economy: A digital opportunity or a digital divide for less-developed regions?

The foundational economy’s heightened traction in academic and policy discussion stems in part from its potential to mitigate challenges faced by less-developed regions. While supporting foundational sectors may contribute to inclusive and sustainable growth, we question whether digitalisation can enable these aims. Through a case study of Wales, we point to the differences in digital capability of foundational and non-foundational businesses in urban and rural parts of the region. We show that while investment in digital infrastructure and digital technology use may support the foundational economy, digital barriers risk countering the benefits of its sectors’ embeddedness and exacerbating spatial divides.
Identification of Constituents and Exploring the Mechanism for Toutongning Capsule in the Treatment of Migraine

Toutongning capsule (TTNC) is an effective and safe traditional Chinese medicine used in the treatment of migraine. In this present study, a multiscale strategy was used to systematically investigate the mechanism of TTNC in treating migraine, which contained UPLC-UESI-Q Exactive Focus network pharmacology and experimental verification. First, 88 compounds were identified by the UPLC-UESI-Q Exactive Focus method for TTNC. Then, the target fishing for these compounds was performed by means of an efficient drug similarity search tool. Third, a series of network pharmacology experiments were performed to predict the key compounds, targets, and pathways. They were protein-protein interaction (PPI), KEGG pathway enrichment analysis, and herbs-compounds-targets-pathways (H-C-T-P) network construction. As a result, 18 potential key compounds, 20 potential key targets, and 6 potential signaling pathways were obtained for TTNC in treatment with migraine. Finally, molecular docking and experimental were carried out to verify the key targets. In short, the results showed that TTNC is able to treat migraine through multiple components, multiple targets, and multiple pathways. This work may provide a theoretical basis for further research on the molecular mechanism of TTNC in the treatment of migraine.

Influence of Various Turbulent Flow Models on the Precision of Simulating a Seawater Desalination-purpose Lift Pump

By using software Fluent,a numerical simulation was performed of a dual volute type seawater desalination-purpose lift pump by employing the standard k-e,RNG k-e and Realizable k-e turbulent flow calculation models respectively.Furthermore,the flow fields inside the volute and blades were analyzed by using the three turbulent flow models.On this basis,a performance prediction was conducted and compared with the test results.The research results show that when the RNG k-e turbulent flow model is used for calculation,the streamlines inside the impeller and volute are comparatively smooth and the performance prediction result is in relatively good agreement with the test one.When the k-e and Realizable k-e turbulent flow model are used for calculation,the streamlines inside the impeller and volute are disordered with vortexes being produced and the performance prediction result has a relatively big difference from the test one.The foregoing indicates that the RNG k-e turbulent flow calculation model is more suitable for the performance prediction of seawater desalination-purpose lift pumps and centrifugal pumps with the same structure.The research results can provide a certain reference for performance prediction and numerical simulation of seawater desalination-purpose lift pumps and centrifugal pumps with the same dual volute structure.
Longitudinal waning of mRNA vaccine-induced neutralizing antibodies against SARS-CoV-2 detected by an LFIA rapid test

Abstract Although mRNA vaccines against SARS-CoV-2 were highly efficacious against severe illness and hospitalization, they seem to be less effective in preventing infection months after vaccination, especially with the Delta variant. Breakthrough infections might be due to higher infectivity of the variants, relaxed protective measures by the general public in “COVID-19 fatigue”, and/or waning immunity post-vaccination. Determining the neutralizing antibody levels in a longitudinal manner may address this issue, but technical complexity of classic assays precludes easy detection and quick answers. We developed a lateral flow immunoassay NeutraXpress™ (commercial name of the test kit by Antagen Diagnostics, Inc.) and tested fingertip blood samples of subjects receiving either Moderna or Pfizer vaccines at various time points. With this device, we confirmed the reported clinical findings that mRNA vaccine-induced neutralizing antibodies quickly wane after 3–6 months. Thus, using rapid tests to monitor neutralizing antibody status could help identify individuals at risk, prevent breakthrough infections, and guide social behavior to curtail the spread of COVID-19.
Microbiological quality assessment of fresh tilapia marketed in the Federal District and of the ice used for its conservation

Tilapia (Oreochromis niloticus) is the most cultivated and consumed freshwater fish in Brazil. The present study aimed to evaluate the microbiological quality of ice and fresh tilapia samples commercialized in the Federal District. Tilapia samples were tested for counts of mesophilic and psychrotrophic bacteria, determination of total and thermotolerant coliforms, Staphylococcus aureus counts and presence of Salmonella. Ice samples were analyzed for determination of total coliforms and thermotolerant coliforms and presence of Escherichia coli. Of the 20 samples of fresh tilapia analyzed, ten samples (50%) presented Salmonella (genetically confirmed through the presence of the invA gene) and, therefore, were unfit for consumption. S. aureus was found in 11 samples (55%), and one sample of fillet presented S. aureus counts (3.15 CFU/g) above the limit allowed by Brazilian legislation (3 log CFU/g). S. aureus colonies were confirmed by detection of CoA gene in molecular analysis. Of the 14 ice samples analyzed, 12 samples (85.7%) were unfit for use in fish conservation due to the presence of total coliforms and 9 ice samples (64.3%) were also contaminated with thermotolerant coliforms. E. coli was isolated from 6 ice samples (42.9%) and confirmed in the molecular analysis through the amplification of the MalB gene. In conclusion, the high contamination of tilapia samples with Salmonella and of the ice used for its conservation with coliforms and E. coli indicates the need for better hygienic practices in the tilapia production chain, to increase its quality and microbiological safety.
