VVUQ of a thermal-hydraulic multi-scale tool on unprotected loss of flow accident in SFR reactor

Within the framework of the French 4th-generation Sodium-cooled Fast Reactor safety assessment, methodology on VVUQ (Verification, Validation, Uncertainty Quantification) is conducted to demonstrate that the CEA's thermal-hydraulic Scientific Computation Tools (SCTs) are effective and operational for design and safety studies purposes on this type of reactor. This VVUQ-based qualification is a regulatory requirement from the French Nuclear Safety Authority (NSA). In this paper, the current practice of VVUQ approach application for a SFR accidental transient is described with regard to the NSA requirements. It constitutes the first practical, progressively improvable approach. As the SCT is qualified for a given version on a given scenario, the transient related to a total unprotected station blackout has been selected. As it is a very complex multi-scale transient, the SCT MATHYS (which is a coupling of the CATHARE2 tool at system scale, TrioMC tool at component scale and TrioCFD tool at local scale) is used. This paper presents the preliminary VVUQ application to the qualification of this tool on this selected transient. In addition, this work underlines some feedback on design and R&D aspects that should be addressed in the future to improve the SCT.

5:3 compressor based neural network with LM Algorithm in Multiplier as Application

In conventional approach for VLSI, implementing large numbers of operations in parallel is possible with NN. The fundamental task of a neural network hardware is not dependent on the implementation technology and are quite constructive in simulating the digital circuits. These NN representations can be incorporated in various applications where in the behaviour of these circuits are essential to get a solution for discrete problems. Therefore, supervised learning algorithms are used to train the computer software. One such algorithm is the L-M method which is one of the powerful and widely used approaches. This paper accounts to the designing and training of a neural network model as computing technique in 5:3 compressor with Lavenberg-Marquardt Algorithm. The performance parameters are significantly remarkable for real time implementation, are presented in the paper.
Passivity-Based PI Control for Receiver Side of Dynamic Wireless Charging System in Electric Vehicles

The dynamic wireless charging for electric vehicles (EVs) is considered an efficient and practical choice to extend the driving range and reduce battery pack size. However, the coupling coefficient between transmitter coils and receiver coil varies rapidly on a large scale during the EVs moving, so it deteriorates the charging performance of dynamic wireless power transfer in EVs, such as the discontinuous charging for the lithium-ion batteries in EVs. Moreover, the charging power and efficiency of the system can also be affected. To solve these issues, a dc–dc converter is added to cascade on the receiver side to improve the output power and efficiency of the system. Furthermore, the passivity-based proportional-integral control is designed for the dc–dc on the receiver side of dynamic wireless charging system to improve the performance against the rapidly changing coupling coefficient. Finally, compared with the conventional proportional-integral-derivative controller, simulation and experimental results are given to show the performance and robustness of dynamic wireless charging system by the proposed method.
Electric Vehicle Ultra-Fast Battery Chargers: A Boost for Power System Stability?

As a consequence of the exponential growth of the electric vehicle (EV) market, DC fast-charging infrastructure is being rapidly deployed all around the world. Ultra-fast charging (UFC) stations are starting to pose serious challenges to the electric power system operation, mostly due to their high peak power demand and unregulated discontinuous operation. To address these issues, local energy storage can be installed, ensuring a smoother grid power absorption profile and allowing to provide grid-supporting features. In this work, a control solution for the grid-side AC/DC converter of next-generation EV UFC stations is proposed. A virtual synchronous compensator (VSC) control algorithm is implemented, in order to lessen the impact of the charging station on the utility and to provide the full spectrum of grid ancillary services (i.e., frequency regulation, reactive power compensation, harmonic reduction, short circuit current generation, etc.). The proposed control strategy is verified experimentally on a downscaled 15 kVA three-phase inverter, emulating the grid front-end of the charging station.
FULLY METALLIC DUAL-BAND 3-D WIRE ANTENNA FOR WI-FI AND WI-MAX APPLICATIONS

—A segmented three-dimensional wire monopole antenna is proposed and optimized to operate in both the Wi-Fi and Wi-Max frequency bands (2.4–2.48 and 3.3–3.7 GHz). The fabrication of the antenna employs both three dimension printing and foundry techniques. The design occupies a total volume of 33 . 8 mm × 30 . 4 mm × 37 . 4 mm, which is equivalent to 0.28 λ 0 × 0 . 25 λ 0 × 0 . 30 λ 0 , where λ 0 is the central wavelength of the lower band. The measurements agree with the simulations and show that the antenna has a − 10 dB impedance bandwidth of 7.53% (2.36 to 2.55 GHz) and 53.87% (2.78 to 4.43 GHz) and a measured − 3 dB axial ratio bandwidth of 19.06% (3.18 to 3.85 GHz) for the second band. For the ﬁrst band, simulations indicate that the polarization is elliptical. The radiation pattern is a near hemispherical coverage toward the upper hemisphere. The measured maximum gain values are 5.6 and 7.3 dB for the lower and upper bands, respectively. The simulated radiation eﬃciency is higher than 98%.
Study on the Correlation between OBF and Age Based on Analysis of Time Domain and Frequency Domain

Many studies indicate that the old people are prone to high blood pressure with the age growing. Elevated blood pressure can lead to the changes of hemodynamic parameters in the blood circulation system, and then cause abnormal changes in the physiological activities of the endothelium, heart and so on. These Characteristic of physiological rhythm reflect the changes of ocular blood pressure and ocular blood flow signals. Thus, we could study on the correlation between ocular blood flow (OBF) and age by analyzing the variety of age on hemodynamic. The paper sets out to fully examine the time domain and frequency domain relationship between OBF and age. Time domain: the paper introduces the thigh cuff method to produce sudden drops in arterial blood pressure (ABP) and study the evolution of the immediate OBF response with LSFG. The LSFG (Laser Speckle Flow graph) allows for quantitative estimation of blood flow in the optic nerve head (ONH), and it is the only noninvasive method that allows sufficient temporal resolution to measure these rapid changes. The paper studies on the relationship between time-domain parameter Kr(L) (The slope of DAR descending curve), Kr(R) (The slope of DAR up curve), Tr(L) (The amount of time it takes to the maximal BF or BP decrease), Tr(R) (The amount of time it takes to the maximal BF or BP increase) and age, respectively. Kr(R), Kr(R), Tr(R) are shown significantly influenced by age changing. Frequency domain: in the case of without any factor, the harmonic content of the envelope waveform of the blood flow velocity in the ophthalmic artery is analyzed in aging and OBF. Cronbach-α reliabilities of the calculated frequency coefficient (FC) and frequency index (FI) are 0.91 and 0.92, respectively. The FI of the ophthalmic artery allows an assessment of the ocular circulation in consideration of age and OBF. The order the age, the smaller the FC, FI in OBF.

Applying advanced technologies in road sign recognition becomes one of the best usages for the safety driving utilizing awareness of road sign. ADAS systems facilitate the self-driving vehicles and drivers in driving and parking functions. It is inevitable that TSR becomes a crucial part for advanced driver-assistance systems. Intelligent driver-assistance system support drivers in stepping aside of conceivable risk and threat. CNN architecture is an extensively applied to solve the potential problems encountered in road sign recognition. To gain more precise recognition, an optimal performer model is essential for automatically recognizing road sign along the road. This paper aims to compare and do performance analysis among three different models. AlexNet, GoogLeNet and HOG-SVM models are built and their performance are analyzed using the road signs data from Myanmar. The experimented result obtained the maximal classification accuracy of GoogLeNet is 98.32% when compared with other two models, AlexNet and HOG-SVM.
Interfacial Hydroxyl Promotes the Reduction of 4-Nitrophenol by Ag-based Catalysts Confined in Dendritic Mesoporous Silica Nanospheres

Surface states—the electronic states emerging as a solid material terminates at a surface—are usually vulnerable to contaminations and defects. This fundamental limitation has prohibited systematic studies of the potential role of surface states in surface reactions and catalysis, especially in more realistic environments. We use the selective reduction of 4-Nitrophenol on silver-covered dendritic mesoporous silica nanospheres (DMSNs) as a prototype example, and show that the dynamic intermediate surface states (DISS) spatially formed by spin orbital coupling (SOC) in singly hydrated hydroxyl complex can significantly enhance the adsorption energy of both 4-Nitrophenol and BH4- anions, by promoting different directions of static electron transfer. The concept of DISS as an electron bath may lead to new design principles beyond the conventional d-band theory of heterogeneous catalysis.

Based on the perovskite film, the perovskite photodetectors with such a simple structure of glass/ CH3NH3PbI3/Au were constructed, and the high resulting responsivity (R) of 5.70 AW−1 was achieved, the as fast as rise and fall response speed of 14.0ms and 13.4ms were showed, which indicates that the perovskite films via doctor- blading have a potential application prospect in constructing low-cost and large-area optoelectronic devices.
Characterization of Agronomical and Quality Traits of Winter Wheat (Triticum aestivum L.) for Fusarium Head Blight Pressure in Different Environments

For food security, it is essential to identify stable, high-yielding wheat varieties with lower disease severity. This is particularly important due to climate change, which results in pressure due to the increasing occurrence of Fusarium head blight (FHB). The objective of this study was to evaluate the stability of winter wheat (Triticum aestivum L.) grain yield under different environmental conditions. Twenty-five winter wheat varieties were evaluated under two treatments (naturally-disease infected (T1) and FHB artificial stress (T2)) during two growing seasons (2018–2019 to 2019–2020) in Osijek and in 2019–2020 in Tovarnik. The interaction between varieties and different environments for grain yield was described using the additive main-effects and multiplicative interaction (AMMI) effects model. The Kraljica and Fifi varieties were located near the origin of the biplot, thus indicating non-sensitivity to different environmental conditions. Principal component analysis (PCA) was used to understand the trait and environmental relationships. PC1 alone contributed 42.5% of the total variation, which was mainly due to grain yield, 1000 kernel weight and test weight in that respective order. PC2 contributed 21.1% of the total variation mainly through the total sedimentation value, test weight, wet gluten and protein content ratio (VG/P) and wet gluten content, in descending order.
Cytotoxic and antiproliferative potential of methanolic extracts of Asparagus racemosus in MDAMB231 cells

The present study was carried out to evaluate the cytotoxic and antiproliferative activity of methanolic extract of Asparagus racemosus in MDAB-231 cells. The qualitative phytochemical analysis of the extract revealed the presence of steroids, alkaloids, flavonoids, glycosides, saponins and diterpenes. MDAMB-231 cells were maintained in RPMI media containing 10 per cent serum and 1 per cent antibiotic and antimycotic solution. The cells were harvested and seeded to 96 well plate at 5×103 cells/mL, incubated for 24 hours at 37˚C with 5 per cent CO2. The cells were treated with 160, 80, 40, 20 and 10µg/mL of the extract for 24 hours and viability was accessed using MTT Assay. Also cells were plated in 6 well plates at concentrations 3×105 cells/mL and exposed to 80, 40, 20 and 10µg/mL of the extract of Asparagus racemosus for acridine orange ethidium bromide (AO/EB) staining. There was a dose dependent decrease in viability of cells exposed to methanolic extracts of Asparagus racemosus with a viability of 15.55+0.193 per cent for cells treated with 160µg/mL. The IC50 was found to be 91.36+ 0.87 µg/mL. The AO/EB staining revealed that most of the cells were dead in extract treated with 80µg/mL where more than 90 per cent of cells were live when treated with 10µg/mL of the extract.
Efficacy of Annona muricata (graviola) in experimental spinal cord injury: biochemical and histopathological analysis

ABSTRACT BACKGROUND: Annona muricata (AM) (graviola) is a plant that grows in tropical regions and is thought to be good for many diseases by local people. Unfortunately, there is no acceptable medical treatment for spinal cord injury (SCI) yet. In our study, we investigated the neuropeotective effects of AM leaf extract on SCI in an experimental rat model. METHODS: A total of 40 Wistar albino rats were randomly divided into five equal groups (n=8). Group 1 was the control group in which only laminectomy was performed. Trauma was induced in four groups after laminectomy. Group 2 (untreated trauma group) was given no medication. In Group 3, a single intraperitoneal dose of methylprednisolone (30 mg/kg) was administered after trauma. The rats in Groups 4 received a low dose (100 mg/kg) of AM leaf extracts by oral gavage one week before trauma while the rats in Group 5 received a high-dose (300 mg/kg) of these extracts by oral gavage one week before trauma. All rats, including the control group, were sacrificed 24 h after the trauma was created. RESULTS: Tissue samples taken to evaluate the neuroprotective effect were examined biochemically and histopathologically. Inflammatory findings in the trauma group were significantly better in both groups treated with AM. There was no difference between the groups in terms of clinical motor examination and inclined plane test results. CONCLUSION: Our histopathological and biochemical results showed that AM is an agent with neuroprotective effects in traumatic SCI.
Common-Mode Current Reduction at DC and AC Sides in Inverter Systems by Passive Cancellation

It is well known that PWM inverters generate common-mode (CM) voltages, which may cause the CM electromagnetic interference and leakage current in the applications such as photovoltaic or motor drive systems. The CM noise issue becomes more severe with the application of silicon-carbide devices, which have higher dv/dt than silicon devices. In this article, a passive cancellation method is proposed by inserting two CM transformers (CMT) into the input and output side of the inverter, respectively. The selection of the turns ratio for two CMTs is analyzed and revealed to achieve the best CM noise cancellation, and the influence of the parasitics in the CMT is investigated as they limit the bandwidth for CM noise cancellation. Compared to the passive filter, floating filter, and the active cancellation method, the proposed method could reduce the CM noise at both sides simultaneously regardless of the CM impedance of the source or the load. A single-phase inverter is built, and the proposed method achieves 40 dB reduction at both sides, which verifies the effectiveness of the proposed method.
Identification of the Design Parameters for a Spacer Fabric Pressure-Mapping Sensor

This work presents an empirical study into the design of fabric pressure sensors, taking into account the electro-mechanical variability of spacer fabric. The saturation of the fabric sensor at high force levels is a major factor limiting the range of measurable pressures. In order to address this, experiments were carried out to investigate several methods of modifying the sensitivity characteristics through the layering and specifications of the textile sheets.
Overexpression of Hepatocyte growth factor in dental pulp stem cells ameliorates the severity of psoriasis by downregulating Th1 and Th17 cells and upregulating Treg cells

Background Psoriasis is a kind of autoimmune disease still lacking standard treatment. Recently, it was demonstrated that mesenchymal stem cells (MSCs) are capable of immunoregulation. The underlying mechanism might involve the secretion of soluble cytokines, such as hepatocyte growth factor (HGF). This study aims to investigate the therapeutic effect of dental pulp stem cells (DPSCs), and hepatocyte growth factor (HGF) overexpressed DPSCs (HGF-DPSCs) on psoriatic mice and the underlying mechanisms. Methods DPSCs were isolated and transfected by adenovirus vector carrying human HGF cDNA (Ad-HGF). DPSCs and HGF-DPSCs were transplanted into the psoriatic mice model. On 7th day of post-transplantation, the mice were euthanized and sacrificed. The psoriatic skin lesions were analyzed by hematoxylin-eosin (H&E) and immunohistochemical staining for histopathological changes, and quantitative real time-polymerase chain reaction (Q-PCR) was applied to detect the expression levels of T-bet, IFN-γ, GATA3, IL-4, RORγt, IL-17A, IL-17F, IL-23, Foxp3 and IL-10. The concentrations of IFN-γ, TNF-α, and IL-17A in the mice blood serum were measured by MILLIPLEX analysis. Human peripheral blood mononuclear cells (PBMCs) were cocultured with DPSCs or HGF-DPSCs under appropriate stimulations. The proliferation index and quantity of T helper 1 (Th1) cells, T helper 2 (Th2) cells, interleukin 17 (IL-17)-secreting helper T (Th17) cells, and regulatory T (Treg) cells were analyzed by flow cytometry. The concentrations of IFN-γ, IL-4, TGF-β1, and IL-6 in the coculture supernatants were quantitated by enzyme linked immunosorbent assay (ELISA) analysis. Results In psoriatic mice, HGF overexpression enhanced the amelioration of epidermal thickening, inflammation infiltration and keratinocyte differentiation by DPSCs treatment. In the psoriatic skin lesions, HGF overexpression enhanced the downregulation of T-bet, IFN-γ, RORγt, IL-17A, IL-17F, IL-23, and upregulation of Foxp3 and IL-10 by DPSCs treatment. When cocultured with PBMCs, HGF overexpression significantly enhanced the downregulation of Th1 and Th17 cells and upregulation of Treg cells by DPSCs, but did not affect their suppression effect on lymphocyte proliferation. Conclusion HGF overexpression enhanced the treatment effect of DPSCs on psoriasis by downregulating Th1 and Th17 cells’ activity and upregulating Treg cells’ activity.
Word Level Language Identification on Code-Mixed English-Bodo Text

Since social media has become an active part of one’s life, people express their views freely in mixed informal languages on such platforms. So, in a multi-lingual country like India, it becomes really difficult for conventional language detectors to identify such languages. This paper mainly aims to detect the language at word level where the code mixed text can be in English-Bodo-Assamese. The data for the same is collected from some related Facebook pages and various classification algorithms are used to predict and compare the accuracy with which the detection is done.
