Design of a Double-Sided LC Compensated Capacitive Power Transfer System With Capacitor Voltage Stress Optimization

Capacitive power transfer (CPT) systems usually have high voltage stresses among coupler plates and compensation capacitors due to small coupling capacitances. High voltages across the coupler plates will incur the strong electric field emission, and it is thus difficult to select compensation capacitors with high voltage stresses. To solve this problem, this brief analyzes a double-sided LC compensated CPT system systematically and finds an operating frequency to realize the load-independent constant current (CC) output and input zero-phase angle (ZPA) simultaneously. Without reactive power in the circuit, a design method is proposed to determine the compensation parameters and operating frequency using the given voltage ratings of coupler plates and compensation capacitors. Thus, voltage stresses among these capacitors could be optimized under their predesigned voltage ratings. The sensitivities of input impedance, output current to variations of compensation parameters are also discussed to realize soft switching. Finally, a prototype of the CPT converter with two types of proposed parameters and symmetric parameters is built to verify the analysis.
Interactive Poster: Displaying English Grammatical Structures

This report describes ongoing work focused at designing a technique for visually representing English grammatical structures. A challenge in representing grammatical structures is to adequately display the linear as well as hierarchical nature of sentences. As our starting point we have adopted a radial spacefilling technique based on Clark’s etymological chart of the 19 century. Clark devised this chart for the purpose of instructing students English grammar. We have automated the chart with basic visual features and interaction techniques. We report the results of a preliminary evaluation that suggests that subjects are able to better identify parts of a sentence after minimal training with the interactive visualization system.
Assessment of Hurricane Vulnerable Populations In Ybor City, Tampa, Florida

During the hurricane season of 2005, the United States witnessed unprecedented events. Particularly, the frequency and magnitude of storms like Hurricane Katrina revealed to the nation that cities did not have adequate emergency plans. The country watched in horror as crucial aspects of storm preparation and recovery were fumbled. Now, the message has come down from the highest level that emergency plans regarding natural disasters need to be reevaluated and retooled to ensure that every person is being cared for equally (Townsend, 2006).
Astragalus alters gut-microbiota composition in type 2 diabetes mice: clues to its pharmacology

Background: Astragalus possesses therapeutic effects for type 2 diabetes (T2D), while its action mechanisms remain to be elucidated. In view of the pathogenic associations between gut microbiota and T2D, we explored the effect of astragalus on gut-microbiota composition of T2D mice. Materials and methods: Modulation effects of astragalus on gut microbiota of T2D-model mice were assessed by 16S rRNA gene sequencing. Results: Inhibited blood-glucose and body-weight levels of T2D mice by astragalus were accompanied by gut microbiota–composition alteration. Astragalus administration significantly increased gut-microbiota richness and diversity in T2D mice and significantly altered the abundance of several bacterial taxa, inducing increased abundance of Lactobacillus and Bifidobacterium. PICRUSt software revealed the relationship between astragalus and T2D. Conclusion: Due to previously reported decreased gut-microbiota richness and diversity and reduced abundance of key species of Lactobacillus and Bifidobacterium, more studies are encouraged to explore the contribution of gut-microbiota alteration by astragalus to its anti-T2D effect.
Immunostimulatory and antibacterial activity of Leuconostoc mesenteroides and its purified exopolysaccharide against extended-spectrum beta-lactamase producing Burkholderia cepacia

ISSN Lactic acid bacteria (LAB) have reported as antifungal, antibacterial, and immunostimulatory agents. Exopolysaccharide (EPS) of lactic acid bacteria effectively could stimulate the production of cytokines by macrophages. This study was aimed to extract, purified, and characterize the EPS from Leuconostoc mesenteroides subsp. Cremoris and to evaluate the immunostimulatory and antibacterial activities of EPS against extended-spectrum beta-lactamase (ESBL) producing Burkholderia cepacia strains. Nine EPSs producing L. mesenteroides subsp. cremoris strains were isolated from local dairy products and the isolated bacteria were identified by using API 50. Eight B. cepacia strains were isolated from different specimens in the hospitals of Medical city, Baghdad. Furthermore, genotypic and phenotypic detection of antibiotic resistance were determined including ESBL genes. EPS of L. mesenteroides subsp. Cremoris was extracted and purified by gel filtration chromatography. EPS physical and chemical analysis were performed to characterize it. Antibacterial and immunomodulatory effect of EPS were studied in vivo using mice and ELISA was used to determine the levels of IL-10 in the mice sera. The extracted EPS was found to have a maximum relative viscosity in water (3.51 dl/g) and maximum specific viscosity (2.93 dl/g), while the intrinsic viscosity recorded 1.41 dl/g. The chemical analysis of the extracted polysaccharide was found to contain the following components, carbohydrates, protein, uronic acids, hexosamines, acetyl groups, ketal linked pyruvate groups, phosphate groups, and sulfate groups, also show the following functional groups under infrared (IR) spectra (hydroxyl, alkanes, carbonyl, carbonyl of carboxylic acid, phosphates, and aliphatic amines). HPLC analysis revealed the presence of mannose as a major component with a calculated molecular weight of 1.71 10 g/mol. Genotypic detection of the blaPER-1 gene among ESBL producing B. cepacia strains showed the presence of blaPER-1 gene in three (42.86%) strains. Furthermore, to confirm the biological potential, the EPS was evaluated for its antibacterial activity against multidrug resistance B. cepacia strains in vitro and the result showed that the purified EPS was more effective than crude EPS in all concentrations. The protective activities of L. mesenteroides and EPS were observed when administered 7 days before and after B. cepacia infection, whereas therapeutic activities were monitored by administering EPS for 7 days after B. cepacia induction. This results revealed that the administration of L. mesenteroides and EPS significantly decreased the number of B. cepacia in liver, spleen, and lung (P<0.05). Furthermore, they enhanced production of IL-10. In conclusion, the L. mesenteroides and its EPSs possess antibacterial and immunostimulator properties and are nontoxic with medicinal importance. Therefore, further studies in human participants should
Winter Survival, Habitat Use, and Hypoxia Tolerance of Montana Arctic Grayling in a Winterkill‐Prone Lake

Winter hypoxia in shallow, ice‐covered lakes can be a significant limiting factor for overwintering fish populations. In this study we tested the hypothesis that low overwinter survival due to winter hypoxia is a limiting factor for a rare, adfluvial population of native Arctic Grayling Thymallus arcticus inhabiting Upper Red Rock Lake, Montana. We used a combined laboratory and telemetry study to document the extent of hypoxia over two winters and to assess the physiological tolerance, behavioral response, and winter survival in relation to hypoxia. In the laboratory, we observed a significant behavioral and physiological response to dissolved oxygen (DO) levels≤ 4.0 mg/L and determined acute 24‐h LC50 values (concentration lethal to 50% of test fish) of 0.75 mg/L DO for adults and 1.50–1.96 mg/L for juveniles at temperatures of 1–3°C. In the field study, we observed dynamic DO concentrations (DO< 1.0 to 10.0 mg/L) during winter ice cover, ranging from persistent near‐anoxic conditions near the bottom to DO concentrations> 4.0 mg/L in the epilimnion. Radiotelemetry indicated adult winter survival rate was high (0.97 in 2014, 0.95 in 2015) and that telemetered fish selected deeper (>1 m), more oxygenated habitat during ice cover. Our study demonstrated that Arctic Grayling have a high tolerance to acute hypoxia exposure and exhibit a physiological and behavioral stress response to DO concentrations≤ 4.0 mg/L. Although hypoxia was present in parts of the lake, sufficient suitable habitat with DO> 4.0 mg/L was available in the lake epilimnion in both study winters. However, winter conditions more severe than those observed during our 2‐year study occur periodically in the lake, and thus winterkill could still be a limiting factor for the population. *Corresponding author: mike.n. davis@gmail.com Present address: Stillwater Sciences, 279 Cousteau Place, Davis, California 95618, USA.

Symmetry of Binary Contrast Contrastive Logic and Modal Logic

The two types of but-hebrew 'aval' and 'ela'. Acknowledgements I am deeply indebted to Michael Kaminski for a variety of illuminating suggestions , and in particular for proposing some of the axioms. Susan Mordechay inspired my observation that the temporal contrastive connectives can be handled by the same paradigm of contrast. She helped a lot with establishing the connections with the linguistic study of the particles considered. Wlodek Zadronsky is thanked for clarifying the relationship of the proposed approach to his own account of the meaning but. I thank MCC for giving me the opportunity to pursue these ideas. In the Technion, my work was supported by the fund for the promotion of research in the technion (administered by the vice-president for research), and by a grant from Keren Man"lam (the fund of vise-president for research). erate special case of the latter, where the Kripke structures interpretations are restricted to one trivial graph only, having two nodes and one accessability edge between them. It is not clear whether such a representation clariies anything. Further work needs to be done also in deening a suitable proof theory, hopefully providing complete axiomatizations of Contrastive Logic in all its variants. In this paper, attention was restricted to the semantic aspects only. Maybe the degenerate view mentioned above may help here. One of the more puzzling consequences of the theory presented is the symmetry of the binary contrast operator, yielding the equivalence but , but This equivalence was challenged by several authors that followed the path of this paper. In particular, 18] presents an alternative deenition of but, based on an extension of the S5 Modal logic, which renders but asymmetric. However, as the authors there admit, the diierence between but and but is a matter of focus and emphasis, both being captured by the Modal logic introduced there. Since I am only interested in (extended) truth conditions, I remain happy with the above equivalence. There is no way to distinguish the two orders merely by semantic contents. Another diierence between my presentation and that of 18], which developes contrast in a diierent way, is in the dynamicity of contrast in their approach. In my theory, all expectations are determined "in advance", reeected by the given world S. According to their view, expectations are formed "in the y". Thus, in but , the expectation of : is formed only after "hearing". This is an …
Smooth approximations of the Aleksandrov solution of the Monge-Ampère equation

We prove the existence of piecewise polynomial, strictly convex, smooth functions which converge uniformly on compact subsets to the Aleksandrov solution of the Monge-Ampère equation. We extend the Aleksandrov theory to the case of a right hand side which is only locally integrable and to convex bounded domains which are not necessarily strictly convex. The result suggests that for the numerical resolution of the equation, it is enough to assume that the solution is convex and piecewise smooth.
Quality of Life in Painful Peripheral Neuropathies: A Systematic Review

Objective Neuropathic pain is a common presenting complaint of patients with peripheral neuropathy (PN) and is considered one of the most disabling neuropathic symptoms, with detrimental effects on patients' quality of life (QoL). The aim of this review was to overview the current literature that focuses on QoL in painful PN of various aetiologies. We sought to clarify the direct effect of pain and its treatment on patients' QoL. Methodology A systematic computer-based literature search was conducted using the PubMed database to search for papers on QoL in painful PN. Information was extracted regarding prevalence, demographics, and response to treatment where relevant. Results We identified 66 articles eligible for inclusion. The vast majority of studies (n=47) focused on patients with diabetic PN. Other aetiologies of painful PN where QoL has been studied to date include gluten, immune-mediated, HIV, chemotherapy-induced, and chronic idiopathic axonal polyneuropathy. Pharmacological treatment is the mainstay in managing pain and has a direct positive and independent effect on the overall QoL. Other nonpharmacological approaches can also be of benefit, either alone or as adjuvant treatments, and are discussed. Conclusion The findings demonstrate that QoL is impaired in painful PN and should not be neglected in clinical practice. Patients' pain management and subsequent impact on QoL should routinely be assessed and monitored.

Antagonistic Effects of Desmedipham on Diclofop Activity

The methyl ester of diclofop [2-(4-(2,4-dichlorophenoxy) phenoxy) propionic acid] was used in all of a series of experiments. When it was applied postemergence, it selectively controlled barnyardgrass [Echinochloa crus-galli (L.) Beauv. ] in sugarbeets (Beta vulgaris L. ‘USH 9′). Tank-mixing diclofop with desmedipham [ethyl m-hydroxycarbanilate carbanilate (ester)] resulted in decreased control of barnyardgrass under greenhouse and field conditions. Losses in activity ranged from 10 to 80%. Delaying application of desmedipham following application of diclofop by 4 days in the greenhouse or in the field resulted in no reduction in barnyardgrass control. Increased rates of diclofop offset the antagonistic effect of desmedipham. Similar losses in activity occurred when Hoe-29152 {methyl-2-[4-(4-trifluoromethylphenoxy)phenoxy] propanoate} was tank-mixed with desmedipham.
Machine learning models for predicting lettuce health using UAV imageries

This paper presents the development and validation of machine learning models for the prediction of water and nitrogen stresses in lettuce. Linear regression and deep learning neural networks, mainly convolutional neural networks (CNNs), are used to train the machine learning models. The data used for the training include both airborne and proximal sensor data. The airborne data used are digital images collected from unmanned aerial vehicles (UAVs) and the normalized difference vegetation index (NDVI) obtained from airborne multispectral images. Chlorophyll meter, water potential meter, and spectroradiometer are the proximal sensors used. Also used for the training are agronomic measurements such as leaf count and plant height. For the validation of the developed models, two sets of tests were performed. The first test used a set of data similar to the training data, but different from the training data. The second test used aerial images of various random lettuce plots at farms obtained from Google Maps. The second test evaluates the models’ portability and performance in an unknown environment using the data that was not collected from the experimental plot. The goal of the machine learning algorithms is to provide precise detection of nitrogen and water stresses on a plant level basis using just the digital images collected from UAVs. This will help reduce the cost associated with precision agriculture.
Online Group Recommendation with Local Optimization

There are some scenarios that need group recommendation such as watching a movie or a TV series, selecting a tourist destination, or having dinner together. Approaches in this domain can be divided into two categories: creating group profiles and aggregating individual recommender list. Yet none of the above methods can handle the online group recommendation both efficiently and accurately and these methods either strongly limited by their application environment, or bring bias towards those users having limited connections with this group. In this work, we propose a local optimization framework, using sub-group profiles to compute the item relevance. Such method can captures and removes the bias existed in the traditional group recommendation algorithms in a certain degree. It can then be used to derive single-user recommendation. We also propose an approach to overcome the problem caused by dynamic change or user updating about his social network, which detects the target user’s group by analyzing the link types between he and his neighbours, and then use the group information to generate his recommendations. Experimental analysis for group and personal recommendation on three different sizes of MovieLens datasets show fairly good results, our method consistently outperform several state-of-the-arts in efficiency. And we also provide the explanations behind the phenomena during the experiments.
Promiscuous pollinators—Evidence from an Afromontane sunbird–plant pollen transport network

Sunbirds play a major role in the pollination of Old World nectivorous plants. However, with the exception of the Cape Floristic Region there is a major knowledge gap around African nectivore interaction networks—a stark contrast from the abundance of neotropical hummingbird–plant networks. Here, we describe a sunbird pollen transfer network (PTN) which we use in conjunction with a sunbird flower visitation network (FVN) to explore levels of sunbird specialization within an Afromontane forest habitat. Both networks were generalized compared with similar‐sized hummingbird networks, reflecting the wide range of flower types visited, the generalist diet, and bill characteristics of sunbirds. Three sunbird species from the genus Cinnyris accounted for 85% of flower visits and 77% of all pollen transported. Of the 17 plant species across both networks, 15 are predominantly pollinated by insects while Anthonotha noldeae (Fabaceae–Caesalpinioideae) and Globimetula braunii (Loranthaceae) depend on sunbirds for seed set. Sunbird species average bill lengths varied between 14.5 mm (the variable sunbird) and 23.6 mm (the Green‐headed Sunbird), but, while more pollen was carried on longer bills, we found no evidence for a relationship between bill length and type of flower visited. Both networks were nested. Some specialization was observed in both networks although this does not appear to be driven much by sunbird–flower trait matching. Overall, our results suggest that in contrast to nectivores elsewhere, factors such as phenology and/or environment, rather than morphology, may play important roles in limiting potential sunbird–flower interactions and need further investigation.
Regular Activity Patterns in Spatio-Temporal Events Databases: Multi-Scale Extraction of Geolocated Tweets

This paper proposes a new technique for the extraction of regular activity patterns at different scales (resolution levels), mined from the microblogging platform Twitter. The approach is based on the recursive application of the DBSCAN clustering algorithm to the geolocated Twitter feed. The proposed technique includes a novel way to obtain ’averaged’ regular activity zones based on the rasterization and aggregation of the Concave Hull of the clusters identified at each resolution level. This technique uses only the spatio-temporal characteristics of the geolocated Twitter feed and does not depend on the data content; therefore it can be extended to work with different spatio-temporal event sources such as mobile telephone records. An experiment was carried out to demonstrate the effectiveness of our technique in the extraction of known activity patterns in the Mexico City Metropolitan Area. Palabras clave: social media, urban activity, geographic data mining.
Effects of selected nonsteroidal anti-inflammatory drugs on acute-phase protein levels after dehorning in Holstein heifers

The purpose of this study was to evaluate the effects of ketoprofen (KTP), flunixin meglumine (FLM), and meloxicam (MLX) administration on acute-phase proteins after dehorning in Holstein heifers. A total of 21 Holstein heifers were enrolled into three groups of equal size (n=7) and administered ketoprofen, flunixin meglumine, or meloxicam, at doses of 2.2 mg/kg, 1.1 mg/kg, and 1 mg/kg body weight, respectively. Serum amyloid A, haptoglobin, and ceruloplasmin levels were determined before the administration of the three drugs (0 hrs) and at 6, 12, 24, 48, and 96 hours post-administration. The mean values (±SD) obtained revealed no significant alteration in APP levels at 0 hrs in any of the three groups. Time-dependent alterations, however, were significant in all groups. Group-time interactions were significant (P < 0.001) for ceruloplasmin concentrations, whereas results for serum amyloid A and haptoglobin levels were deemed non-significant. Inter-group interaction revealed no significant findings regarding serum amyloid A and ceruloplasmin levels, but haptoglobin levels showed a significant difference between the KTP and FLM groups at 48 hrs. It may therefore be reasonably suggested that KTP, FLM, and MLX could all be administered to effect slight changes in acute phase proteins.
