Real-Time Implementation of CLMS Algorithm in 3P4W Solar PV-BES-Based Microgrid System

A solar photovoltaic (PV)—battery energy storage (BES) involved the microgrid (MG) system is presented in this article. It contains a bidirectional dc–dc converter (BDDC), which is responsible for extracting the maximum power output from the PV array by regulating the dc-link voltage to the maximum power point (MPP) voltage of the PV array. Whenever the PV array is not delivering any power, then the control of the BDDC is automatically shifted to regulate the dc-link voltage to a constant dc voltage. Thus, the BDDC regulates the dc-link voltage to the desired voltage in the presence of BES in the MG. Whenever the BES is disconnected from the MG, then the voltage source converter (VSC) regulates the dc-link voltage to the desired value. Thus, it enhances the reliability of the system. The neutral current compensation is performed by the zig-zag transformer, which is connected at the load end. The VSC performs different functions such as mitigation of harmonics and reactive power, balancing of grid currents, and the regulation of the dc-link voltage in the absence of BES. The system behavior is analyzed under different operating conditions in the simulation platform and in the laboratory conditions on a prototype.
Effect of Korean Red Ginseng on the Stability of the Tight Junction of Intestinal Epithelial Cells

Bioactive components involved in the tight junction stabilization of intestinal epithelial cells from Korean red ginseng were studied by analyzing transepithelial electrical resistance (TEER) values of the Caco-2 cell monolayer between the apical and basolateral sides for 96 hr. The treatment with less than of the Korean red ginseng extract to the apical side of Caco-2 cell monolayer gave higher TEER values than the control. However, the treatment with more than of the Korean red ginseng extract drastically decreased the TEER values, and these effects were not due to its cytotoxicity. When fractions of low molecular weight compounds, polysaccharides, proteins, saponins, and polyphenols derived from Korean ginseng were applied to the apical side of the Caco-2 cell monolayer, polyphenols showed high tight junction stabilizing activity and saponins showed low activity, but the others showed no significant activity. These results suggest that Korean red ginseng might be useful for the prevention of food allergy by stabilizing the tight junction of intestinal epithelial cells leading to hindering absorption of food allergens.
Test Chips With Scan-Based Logic Arrays

This article proposes a scan-based test chip architecture targeting the diagnosis of multiple faults consisting of input pattern faults, stuck-at faults, and bridging faults (BFs). The architecture consists of a 2-D array of logic blocks and two sets of scan chains isolating the logic blocks. The scan chains are used to fully control and observe the logic blocks so as to enhance the testability and diagnosability of test chips. An efficient diagnostic procedure composed of two tests is developed to carry out the defect diagnosis process. Evaluation results show that the proposed procedure can always achieve 100% accuracy for single faults. When double faults containing 0, 1, and 2 BFs are considered, the proposed procedure can achieve 100% accuracy for 99.38%, 98.398%, and 97.416% of the faults and achieve perfect resolution for 98.81%, 98.006%, and 97.202% of the faults, respectively. Moreover, no matter how many faults exist, as long as no fault affects the scan registers, the proposed procedure can report all faulty logic blocks.
Strengths and potential pitfalls of hay-1 transfer for ecological restoration revealed 2 by RAD-seq analysis in floodplain Arabis 3 species 4 5

13 Achieving high intraspecific genetic diversity is a critical goal in ecological restoration as it 14 increases the adaptive potential and long-term resilience of populations. Thus, we investigated 15 genetic diversity within and between pristine sites in a fossil floodplain and compared it to sites 16 restored by hay-transfer between 1997 and 2014. RAD-seq genotyping revealed that the 17 stenoecious flood-plain species Arabis nemorensis is co-occurring with individuals that, based on 18 ploidy, ITS-sequencing and morphology, probably belong to the close relative Arabis sagittata, 19 which has a documented preference for dry calcareous grasslands but has not been reported in 20
Characterization of GRB2 and SOS1 binding downstream of TCR activation

Despite their essential role in protection, T cells can be dangerous if unregulated. Dysfunctional T cell activity has been implicated in numerous diseases, including the failure of organ transplants, allergic reactions, multiple sclerosis, and coronary artery disease. Signal transduction pathways activated by the T cell receptor (TCR) are good targets for the development of therapies. However, we must first better understand the mechanisms of intracellular signaling that occur when a T cell is activated. This thesis focuses on the scaffold protein LAT and its role in T cell activation. The localization of signaling proteins into LAT-nucleated complexes and subsequent aggregation of these complexes into microclusters is vital for the activation of intracellular signaling pathways, and the effector functions of T cells. Following TCR stimulation, LAT is phosphorylated and binds SH2 domain containing molecules, such as the adaptor protein Grb2. One LAT molecule is capable of binding up to three Grb2 molecules at one time. Grb2 also binds to the proline rich regions of several proteins, including SOS1. Recent studies indicate that at physiological ratios of Grb2 and SOS1, two Grb2 molecules bind to one SOS1 proline rich region, and this 2:1 stoichiometry is essential for LAT oligomerization and cluster formation. The interaction of Grb2 and SOS1 is considered to be a model SH3 domain interaction, and has biased our understanding of these relationships for decades. Many studies have focused on the association between the Grb2
Lonely and thinking about the past: the role of time perspectives, Big Five traits and perceived social support in loneliness of young adults during COVID-19 social distancing

Background In the spring of 2020, due to the COVID-19 pandemic, the Polish government introduced a policy of social distancing Being apart from one's social network had the potential to evoke feelings of loneliness The aim of the study was to find out how time perspectives might contribute to feeling lonely during the social distancing period, controlling for Big Five personality traits and perceived social support participants and procedure The study was online, questionnaire-based and cross-sectional (N = 964) and was conducted among young adults (aged 18-35) at the end of the third week of social distancing in Poland results The results suggested that the Past-Negative time perspective remained significant predictor of loneliness when controlling for Big Five traits and perceived social support Emotional stability, extroversion and perceived social support were also significant predictors of low loneliness conclusions Negative beliefs about the past may contribute to experiencing greater loneliness when being apart from one's social network © 2020 by the authors Licensee MDPI, Basel, Switzerland
An integrated approach for carbonate reservoir characterization: a case study from the Linguado Field, Campos Basin

The main reservoirs in the Linguado Field are grainstone and packstone carbonates composed of oolites, oncolites, pelloids, and rare bio-clasts, of the Quissamã Formation (Albian-age) and coquinas of the Coqueiros Formation (Aptian-age). Within Quissamã Formation, facies have high porosity variations and their 3D characterization is of utter importance to allow for a better location of the wells. The objective of this study was a volumetric characterization of Quissamã Formation by means of an adapted classical workflow composed of well-seismic tie, seismic preconditioning, seismic interpretation, seismic inversion, petrophysical properties estimation, and porosity geostatistical modeling. Seismic inversion results allowed the interpretation of a horizon to separate the carbonate platform in an upper zone, with low acoustic impedance, from a lower zone, with high acoustic impedance. Finally, behavioral knowledge of acoustic impedance and the porosity distribution within the Albian carbonate platform helped to better characterize the distribution of carbonaceous facies allowing the confirmation that commercial wells were drilled in low acoustic impedance and high porosity regions. It was also possible to confirm that a well, declared as noncommercial, was drilled in a poor reservoir region with high acoustic impedance and low porosity and identified other locations that were not yet drilled but could represent potential targets.
Spatial and aspatial clustering analysis of PM2.5 concentrations in Temuco, Chile using mobile measurements

Air pollution due to wood burning produces severe health and environmental problems. Clustering methods are needed to estimate PM2.5 exposures, and identify locations with high PM2.5 concentrations. This study performed a spatial and aspatial clustering analysis of PM2.5 pollutant collected in a mobile campaign in the conurbation of Temuco and Padre Las Casas, Chile. The Getis Ord Gi statistic was employed to obtain spatial variability of PM2.5 concentrations, and a K-Means clustering method was used to group PM2.5 concentrations with a aspatial perspective. In addition, an integrated spatial and aspatial clustering approach was implemented with the PM2.5 concentration and measurement spatial location. The comparison results suggest that integrating the spatial and aspatial clustering methods yield high quality partitions when considering spatial information.
Multisource Acoustoelectric Imaging With Different Current Source Features

Based on acoustoelectric (AE) effect, AE imaging is a potential neuroimaging technique for mapping brain electrical activity with high temporal and spatial resolution. Acting as multiple current sources in the brain, neurons discharge with complex spatial distribution and current features, including frequency and amplitude. However, the current AE imaging mainly focuses on source with single feature, which is lack of multisource AE imaging. To make a step toward developing AE imaging as a clinical imaging technique, this work evaluates and verifies multisource AE imaging with different current source features. Three phantom experiments were implemented with different source configurations, including 1-source, 2-source with different frequencies and amplitudes, and 3-source with different frequencies and amplitudes. Each source with different features can be clearly imaged with a high resolution (1–2 mm of the −6-dB peak). Besides, according to frequency spectrum, the frequency feature can be effectively distinguished. In addition, based on the statistic results of AE signal amplitudes, there are significant differences between each source with different amplitudes. In this study, the multisource with different frequencies and amplitudes is not only clearly imaged but also effectively extracted corresponding features from AE signals. It validates the feasibility of multisource AE imaging with different current source features, which is critical to further research and application of complex AE neuroimaging.
Performance, carcass traits, and non-carcass components of feedlot finished lambs from different residual feed intake classes

This study aimed to assess the performance, carcass traits, and non-carcass components of feedlot finished Texel crossbred lambs from different residual feed intake classes (RFI). Forty-seven uncastrated male Texel crossbred lambs (¾ Texel + ¼ Pantaneira) tested here were 4-month-old with an initial weight of 29.9 ± 5.5 kg. The lambs were confined for 70 days for individual dry matter intake (DMI) and average daily gain (ADG) assessment. The diet containing corn silage was provided as roughage, while the concentrate consisted of corn grain, soybean meal, urea, and mineral mixture with a 40:60 roughage to concentrate ratio and 76.34% total digestible nutrients (TDN). After confinement for 70 days, the lambs were slaughtered to assess carcass traits and non-carcass components. Based on the RFI, lambs were divided into three classes according to the standard deviation (sd): Positive RFI (inefficient, 0.5 above the mean), Negative RFI (efficient, 0.5 below the mean), and Medium RFI (intermediate). Classes with Negative (efficient) and Positive RFI (inefficient) showed no differences in ADG (0.321 vs 0.306 kg; P > 0.05). Dry matter intake (g d-1), and percentage of body weight (BW) differed significantly between the RFI classes (P < 0.05). Compared to lambs in the inefficient class, those in the efficient class (Negative RFI) showed a 9% reduction in DMI and had the same ADG. The lambs in either Positive or Negative RFI classes showed no weight differences between non-carcass components (P > 0.05). The RFI classes showed no differences in shrunk body weight, hot carcass weight, hot dressing, and weight of commercial cuts (P > 0.05). They showed no differences in neck, shoulder + shank, loin, rack, flank steak, rack cap off, and leg weights (P > 0.05). Our results indicate that improvement in feed efficiency, as a function of the RFI index, does not compromise performance and carcass traits of Texel crossbred lambs.
Comparative analysis of Synthetic Physical Interactions with the yeast centrosome

The yeast centrosome or Spindle Pole Body (SPB) is situated in the nuclear membrane, where it nucleates spindle microtubules and acts as a signalling hub. Previously, we used Synthetic Physical Interactions to map the regions of the cell that are sensitive to forced relocalization of proteins across the proteome [Berry et al., 2016]. Here, we expand on this work to show that the SPB, in particular, is sensitive to the relocalization of many proteins. This work inspired a new data analysis approach that indicates that relocalization screens may produce more growth defects than previously reported. A set of associations with the SPB result in elevated SPB number and since hyper-proliferation of centrosomes is a hallmark of cancer cells, these associations point the way for the use of yeast models in the study of spindle formation and chromosome segregation in cancer.
Incidental Attitude Formation via the Surveillance Task: A Registered Replication Report of Olson and Fazio (2001)

Evaluative conditioning (EC) is one of the most widely-studied procedures for establishing and changing attitudes. The surveillance-task (Olson & Fazio, 2001) is a highly cited EC paradigm, and one that is claimed to generate attitudes without awareness. The potential for EC effects to occur without awareness continues to fuel conceptual, theoretical, and applied developments. Yet few published studies have used this task, and most are characterized by small samples and small effect sizes. We conducted a high-powered (N = 1478 adult participants), preregistered close replication of the original surveillance-task study. We obtained evidence for a small EC effect when ‘aware’ participants were excluded using the original criterion – therefore replicating the original effect. However, no such effect emerged when three other awareness criteria were used. We suggest that there is a need for caution when using evidence from the surveillance task effect to make theoretical and practical claims about ‘unaware’ EC effects.
Developing a Security Testbed for Industrial Internet of Things

While achieving security for Industrial Internet of Things (IIoT) is a critical and nontrivial task, more attention is required for brownfield IIoT systems. This is a consequence of long life cycles of their legacy devices which were initially designed without considering security and IoT connectivity, but they are now becoming more connected and integrated with emerging IoT technologies and messaging communication protocols. Deploying today’s methodologies and solutions in brownfield IIoT systems is not viable, as security solutions must co-exist and fit these systems’ requirements. This necessitates a realistic standardized IIoT testbed that can be used as an optimal format to measure the credibility of security solutions of IIoT networks, analyze IIoT attack landscapes and extract threat intelligence. Developing a testbed for brownfield IIoT systems is considered a significant challenge as these systems are comprised of legacy, heterogeneous devices, communication layers and applications that need to be implemented holistically to achieve high fidelity. In this article, we propose a new generic end-to-end IIoT security testbed, with a particular focus on the brownfield system and provide details of the testbed’s architectural design and the implementation process. The proposed testbed can be easily reproduced and reconfigured to support the testing activities of new processes and various security scenarios. The proposed testbed operation is demonstrated on different connected devices, communication protocols and applications. The experiments demonstrate that this testbed is effective in terms of its operation and security testing. A comparison with existing testbeds, including a table of features is provided.
An Improved Encoder–Decoder Network for Ore Image Segmentation

Accurate segmentation of ore images plays a significant role in automatic geometric parameter detecting and composition analyzing of ore dressing progress. Semantic segmentation based on deep learning is a promising method for accurate ore image segmentation. However, the similar appearance with low contrast and blurry boundary of ores in image hamper segmentation accuracy. Moreover, it is difficult to train a deep network due to limited available ore images. In this work, an improved encoder-decoder network based on U-Net is proposed to handle above challenges. A contour awareness loss (CAL) is proposed to improve model sensitivity to misclassified pixels, pixels of similar appearance, and pixels near the boundary. The proposed scheme is verified on ore images by benchmarking against state-of-the-art segmentation methods. Experiment results show that the proposed scheme achieves 88.6% pixel-wise accuracy (PA) and 66.0% mean intersection over union (mIoU).
Evaluation of synergistic potential of plant growth promoting rhizobacteria with Rhizobium in mungbean (Vigna radiata L.)

A pot experiment was conducted in glass house at PAU research farm, Ludhiana, Punjab, India to evaluate effect of co-inoculation of plant growth promoting rhizobacteria with Rhizobium on mungbean productivity. Coinoculation showed a significant increase at 5% in nodule number, nodule dry weight, shoot and root dry and fresh weight, plant length, no. of pods, chlorophyll and leghaemoglobin content, over Rhizobium alone. Application of PGPRs R-4, R-6, S-5, S-9 and S-11 along with Rhizobium further enhanced the grain yield over Rhizobium inoculation alone. Rizobacterial isolates R-6 and S-11 co-inoculated with Rhizobium showed better result than other isolates.These plant beneficial rhizobacteria may decrease the global dependence on various hazardous agricultural chemicals used in mungbean.
Human Navigation Without and With Vision - the Role of Visual Experience and Visual Regions

Human navigation relies on a wide range of visual retinotopic cortical regions yet the precise role that these regions play in navigation remains unclear. Are these regions mainly sensory input channels or also modality-independent spatial processing centers? Accordingly, will they be recruited for navigation also without vision, such as via audition? Will visual experience, or the lack thereof, affect this recruitment? Sighted, congenitally blind and sighted-blindfolded participants actively navigated virtual mazes during fMRI scanning before and after navigating them in the real world. Participants used the EyeCane visual-to-auditory navigation aid for non-visual navigation. We found that retinotopic regions, including both dorsal stream regions (e.g. V6) and primary regions (e.g. peripheral V1), were selectively recruited for non-visual navigation only after the participants mastered the EyeCane demonstrating rapid plasticity for non-visual navigation. The hippocampus, considered the navigation network’s core, displayed negative BOLD in all groups. Our results demonstrate the robustness of the retinotopic nodes modality-independent spatial role in non-visual human navigation to lifelong visual-deprivation, demonstrating that visual input during development is not required for their recruitment. Furthermore, our results with the blindfolded group demonstrate this recruitment’s robustness even to brief blindfolding, but only after brief training, demonstrating rapid task based plasticity. These results generalize the wider framework of task-selectivity rather than input-modality as a brain organization principle to dorsal-stream retinotopic areas and even for the first time to the primary visual cortex. Highlights Both visual and non-visual navigation recruit retinotopic regions After training blindfolded subjects selectively recruit V1 & V6 for navigation This holds also for participants with no visual experience (congenitally blind) The medial temporal lobe showed non-selective Negative BOLD in all groups Declaration of interests All authors declare that they have no conflicts of interests.
