Developmental toxicity induced by Cu(OH)2 nanopesticide in zebrafish embryos

The current study evaluates the adverse effects of Cu(OH)2 nanopesticide (CNPE) on the early life stages of zebrafish (Danio rerio). The developmental toxicity was determined using different parameters such as mortality (including LC50), hatching, heart rates, malformations, and alteration of the gene expressions. Zebrafish embryos (4 hpf‐hours postfertilization) were exposed to 1.0, 2.0, 4.0, 8.0, and 16.0 mg/l CNPE doses until 96 hpf. The 96 hours LC50 was recorded at 6.258 mg/l. Seventy‐two hpf total malformation index values for 2.0, 4.0, and 8.0 mg/l CNPE doses were 4.3, 7.2 and 7.9, respectively. 1.0 mg/l CNPE is not toxic for the zebrafish embryos/larvae. 2.0 to 8.0 CNPE doses caused some abnormalities in embryos/larvae morphology, including lack of body parts, tail deformities, chorda deformity, bubbled head, scoliosis, lordosis, weak or non‐pigmentation, decreased heart rate and larva length. 16.0 mg/l CNPE caused mortality in 72 hpf. The expression levels of seven immune system‐related genes (il‐1β, il‐8, cebp, tlr4, hsp70, NF‐kB, and mtf‐1) were examined. The transcription level of il‐1β, il‐8, tlr4, hsp70, and NF‐kB genes significantly increased in the CNPE exposure groups. While the expression of the mtf‐1 gene considerably decreased, the cebp gene expression level did not change in the 4.0 and 8.0 mg/l CNPE doses. In conclusion, CNPE could induce developmental toxicity with malformations in embryos/larvae and alter the gene expression.
A note on the protein metabolism in lambs fed the diet supplemented with bioplex and linseed or linseed oil.

In trial R two groups of rams, beginning with 16 kg live weight (control group and experimental group - Rc and Re, n=8 and n=9) were fattened with the concentrate containing 231 g CP and 12.0 MJ ME per kg dry matter. During 3 months Re lambs were given 3 g linseed with 3 g bioplex mineral supplement per day/ram. Both Rc and Re lambs were slaughtered at the age of 140 days. In trial E two groups of ewes, beginning with 8 kg live weight (control group and experimental group - Ec and Ee, n=10 and n=11) were fattened with the concentrate (207g CP and 12.5 MJ ME/kg DM). Moreover, Ee lambs were given 3 g linseed oil with 3 g bioplex mineral supplement per day/ewe during 5 months. Both Ec and Ee lambs were slaughtered at the age of 158 days.In
Two-Stage Hierarchical Congestion Management Method for Active Distribution Networks With Multi-Type Distributed Energy Resources

More and more distributed energy resources (DERs) are being integrated into the distribution networks raising the new concerns of secure and economic operations. Some traditional distribution networks are upgraded to active distribution networks (ADNs) which can communicate with and control the DERs. A microgrid connected to an ADN can be coordinated with the ADN. In this paper, a two-stage hierarchical congestion management mechanism is proposed for an ADN connected with multi-type DERs and microgrids. At the first stage, a hierarchical optimization model is built considering the dispatch of direct control resources (DCRs) and microgrids. An analytical target cascading (ATC) method is employed to optimize the microgrid autonomy model and the ADN optimization model simultaneously. A second stage optimization is designed to deal with the case when the control of DCRs and microgrids is not enough to completely eliminate the congestion. A congestion management model calling for the ancillary services provided by DERs is established, with an objective of minimizing the operational cost of distribution system operator (DSO). Case studies are carried out on modified IEEE 33 and PG&E 69 bus systems. The simulation results show that the proposed method can balance the interests of different stakeholders and eliminate the network congestion efficiently.
A Robust and Versatile Pipeline for Automatic Photogrammetric-Based Registration of Multimodal Cultural Heritage Documentation

Imaging techniques and Image Based-Modeling (IBM) practices in the field of Cultural Heritage (CH) studies are nowadays no longer used as one-shot applications but as various and complex scenarios involving multiple modalities; sensors, scales, spectral bands and temporalities utilized by various experts. Current use of Structure from Motion and photogrammetric methods necessitates some improvements in iterative registration to ease the growing complexity in the management of the scientific imaging applied on heritage assets. In this context, the co-registration of photo-documentation among other imaging resources is a key step in order to move towards data fusion and collaborative semantic enrichment scenarios. This paper presents the recent development of a Totally Automated Co-registration and Orientation library (TACO) based on the interoperability of open-source solutions to conduct photogrammetric-based registration. The proposed methodology addresses and solves some gaps in term of robustness and versatility in the field of incremental and global orientation of image-sets dedicated to CH practices.
Prevalence and Distribution of the hmwand hia Genes and the HMW and Hia Adhesins among Genetically Diverse Strains of Nontypeable Haemophilus influenzae

ABSTRACT Nontypeable Haemophilus influenzae is a common cause of human disease and initiates infection by colonizing the upper respiratory tract. In previous work we identified high-molecular-weight adhesins referred to as HMW1 and HMW2, expressed by nontypeable strain 12, and determined that most strains of nontypeable H. influenzae express one or two antigenically related proteins. More recently, we determined that some strains lack HMW1- and HMW2-like proteins and instead express an adhesin called Hia. In the present study, we determined the prevalence and distribution of thehmw and hia genes in a collection of 59 nontypeable strains previously characterized in terms of genetic relatedness. Based on Southern analysis, 47 strains contained sequences homologous to the hmw1 and hmw2 genes and nine strains contained homologs to hia. No strain harbored bothhmw and hia, and three strains harbored neither. Although the hmw and hia genes failed to define distinct genetic divisions, the hmw-deficient strains formed small clusters or lineages within the larger population structure. Additional analysis established that the IS1016insertion element was uniformly absent from strains containinghmw sequences but was present in two-thirds of thehmw-deficient strains. As IS1016 is associated with the capsule locus (cap) in most encapsulated strains of H. influenzae, we speculate thathmw-deficient nontypeable strains evolved more recently from an encapsulated ancestor.
Genetic Variability Influences Carotenoid, Vitamin, Phenolic, and Mineral Content in White, Yellow, Purple, Orange, and Dark-orange Carrot Cultivars

ADDITIONAL INDEX WORDS. Daucus carota, colored carrot varieties, β-carotene, vitamin E, vitamin C, antioxidant compounds ABSTRACT. Carrot (Daucus carota L.) is ranked among vegetables as the most consumed and the best provitamin A provider. Moreover, carrot also contains vitamins, phenolic compounds, and other antioxidant micronutrients. The infl uence of carrot genetic background on the content of several micronutrients was investigated. Carotenoids and vitamins (C and E) were analyzed by HPLC in 20 varieties of carrot, and antioxidant activity of carrots was investigated with colorimetric methods (ORAC and Folin-Ciocalteu). There were large differences among cultivars in carotenoid content (0.32 to 17 mg/100 g of fresh weight). In yellow and purple carrots, lutein represents nearly half of the total carotenoids. By contrast, in orange carrots, β-carotene represents the major carotenoid (65%). The concentration of vitamin E ranged from 191 to 703 µg/100 g of fresh weight, whereas the concentration in ascorbic acid ranged from 1.4 to 5.8 mg/100 g. For all these components, dark-orange carrots exhibited the highest values. Signifi cant differences among these 20 varieties were also recorded for mineral and total phenolic compound concentrations. Purple and dark- orange carrots could be preferred to usual carrot varieties to benefi t from their specifi c micronutrients (anthocyanins, carotenoids, or vitamin E). ORAC is a complex refl ection of phytomicronutrients but is not tightly linked to vitamin C levels, as shown for white carrots, which are rich in this vitamin.
FDTD Analysis of Offset-fed Wideband Slot Antennas

In this paper, finite-difference time-domain (FDTD) method is used to analyze the reflection characteristics of three wideband slot antennas – the basic designs for S and C-bands, and a directive design for the C-band. The input impedance and corresponding return loss responses are computed. Near-field plots of the slot antenna are generated to identify the operating mode. FDTD results are compared with that from commercial simulation tools, and are in good agreement.
The use of chemicals in aquafeed

Various chemicals and additives used in fish and shrimp feeds may have impacts on animal health, product quality and the environment.

Phase Distribution Optimization for 1-Bit Transmitarrays with Near-Field Coupling Feeding Technique

The paper presents a consideration of the optimum initial phase distribution for 1-bit transmitarrays with near-field coupling feeding technique. The study is based on the array factor decomposition into a series of continuous aperture distributions, which naturally includes the phase quantization errors. The previously proposed virtual focus approach is compared with the optimum quadratic initial phase distribution. Both methods are found to be very similar for specific values of distribution parameters in terms of far-field performance. Some further sidelobes level improvement is proposed.
Leveled Adaptively Strong-Unforgeable Identity-Based Fully Homomorphic Signatures

The identity-based homomorphic signature (IBHS) enables an untrusted server to run some computation over the outsourced data and derive a short signature, vouching for the correctness of the output of the computation, while greatly simplifying key management. To our knowledge, constructions of IBHS have been few and far between. However, the existing IBHS schemes, which either handle only linear functions or has a large public key parameter and satisfies only the artificial notion of selective security. In this work, we construct the first leveled adaptively secure identity-based fully homomorphic signature (IBFHS) schemes without additional public parameters, which can be used to sign many different datasets. Thereby positively answering the open question of constructing a leveled IBFHS scheme with short public parameters, proposed by Wang et al., (ISC, 2015, Springer). We achieve the stronger security and better parameters by using the trapdoor vanishing and vector encoding technique. In our scheme, the size of every evaluated signature depends only logarithmically on the size of the input dataset, and the complexity of verifying a signature for a computation can be amortized when verifying the same computation on many different datasets. Furthermore, we prove that our construction is strongly-unforgeable against adaptively chosen identity and message attacks under the small integer solution ( $\mathsf {SIS}$ ) assumption in standard lattices.
Mechanical Fault Diagnosis of GIS Based on MFCCs of Sound Signals

Mechanical fault diagnosis of Gas Insulated Switchgear (GIS) is a popular research topic in recent years. Inspired by the fact that experienced inspectors can detect the failure of GIS only by sound, this paper proposes a novel framework for mechanical fault diagnosis based on sound classification. We extract the Mel Frequency Cepstral Coefficient (MFCC) features from the input sound signal and make an improvement to adapt to the underlying features of the GIS’s sounds. Using machine learning, we classify the extracted features with a support vector machine (SVM) to obtain a model of mechanical fault diagnosis of GIS based on sound signals. We outperform the traditional MFCC features by a significant margin, especially when the input sound signal is disturbed by noises. The F1-score can be increased by 2.47% to 21.59% with the change of the signal-to-noise (SNR) ratio.
Growth Responses of Carya ovata (Juglandaceae) Seedlings to Experimental Sun Patches

Abstract The heterogenous structure of eastern deciduous forest canopies creates an understory light continuum ranging from deep shade to extended periods of direct solar irradiance below large canopy gaps. We designed an experiment to explore how shagbark hickory (Carya ovata (Mill.) K. Koch; Juglandaceae) seedlings respond to changes in both the total amount of available light and the durations of experimental sun patches. Seedlings were grown in a common garden under shadehouses where they experienced one of two light levels (high vs. low light), one of two sun patch durations (short vs. long duration) and 100% light (control). Over the growing season, seedlings responded morphologically to the amount of available light by changes in mean stem height, weight, basal diameter, specific leaf mass, chlorophyll content, taproot length, primary and secondary root weight and root ash weight. Chlorophyll content and stem height were negatively related to the amount of available light whereas the other morphological characters were positively related to increased amounts of light. Changes in the duration of experimental sun patches significantly affected stem biomass, basal diameter, secondary root dry weight and root ash weight independent of total light amount. Though the effects of sun patch duration were not as pronounced as those found for amount of light, our results demonstrate the importance of including periods of direct light in experimental designs involving responses of seedlings to varying light regimes. The ecological responses of many hardwoods, especially those of midshade tolerance, to the middle portion of the gap-understory continuum remain poorly studied.
Evaluation of LJ1-01 Nighttime Light Imagery for Estimating Monthly PM2.5 Concentration: A Comparison With NPP-VIIRS Nighttime Light Data

Air quality degradations caused by fine particulate matter (PM2.5) can lead to various health problems, and accurate PM2.5 data are critical for managing the environment and ensuring public health. Radiation signals collected by nighttime light (NTL) remote sensing satellites are influenced by PM2.5 concentrations, and thus, incorporating NTL imagery in statistical models has been widely used to predict PM2.5 concentrations. However, scarce work has been carried out with new-generation NTL data from the LJ1-01 satellite, which has a fine spatial resolution and wide measurement range. In this study, we integrated satellite observation data and meteorological data to construct five models based on the geographically weighted regression to validate the feasibility of LJ1-01/NPP-VIIRS in Moderate Resolution Imaging Spectroradiometer AOD-based PM2.5 prediction in the Beijing–Tianjin–Hebei region. The models were validated by the cross-validation method. The results showed that the addition of NTL information could improve the performance of the PM2.5 prediction model. The seasonal R2 with NTL in AOD-PM2.5 model have improved by 5.07%, 4.50%, 2.95%, and 2.56% in model fitting and 1.20%, 1.75%, 2.20%, and 4.41% in cross-validation. Furthermore, the LJ1-01 NTL data revealed additional details and improved the prediction accuracy, compared with the NPP-VIIRS in AOD-PM2.5 model, the seasonal R2 with LJ1-01 in AOD-PM2.5 model increased by 1.16%, 1.79%, 0.76%, and 1.15% in model fitting and 1.04%, 0.85%, 0.78%, 1.37% in cross-validation. Thus, our findings indicate that LJ1-01 and NTL data have the potential for predicting PM2.5 and that they could constitute a useful supplemental data source for estimating ground-level PM2.5 distributions.
Improving Physical Layer Security Technique Based on 4-D Antenna Arrays with Pre-Modulation

Four-dimensional (4-D) antenna arrays formed by introducing time as the forth controlling variable are able to be used to regulate the radiation fields in space, time and frequency domains. Thus, 4-D antenna arrays are actually the excellent platform for achieving physical layer secure transmission. However, traditional direction modulation technique of 4-D antenna arrays always inevitably leads to higher sidelobe level of radiation pattern or less randomness. Regarding to the problem, this paper proposed a physical layer secure transmission technique based on 4-D antenna arrays, which combine the advantages of traditional phased arrays, and 4-D arrays for improving the physical layer security in wireless networks. This technique is able to reduce the radiated power at sidelobe region by optimizing the time sequences. Moreover, the signal distortion caused by time modulation can be compensated in the desired direction by pre-modulating transmitted signals.
Beam steering in a Time Switched Antenna Array with reduced Side Lobe Level using Evolutionary Optimization Technique

Steering the main beam of a time modulated antenna array (TMAA) with reduced side lobe level (SLL) is proposed in this paper. Linear antenna array of 16 and 18 isotropic elements are considered here with time modulation. Predefined switching scheme has been used to generate the desired radiation pattern at fundamental and multiple harmonic frequencies to achieve beam steering. A modified version of particle swarm optimization (PSO) with wavelet mutation is used to lower the overall side lobe level. Switching time sequences and inter element spacing between radiating elements are optimized to get the desired radiation pattern with minimal changes in first null beam width (FNBW).
A Novel Wearable RF Head Coil for High Resolution 7T Magnetic Resonance Imaging

In this paper, a new structure of 7T magnetic resonance imaging RF coil has been designed and presented. The flexibility of this coil distinguishes it from others traditional coils. The mentioned array coil consists of 8-channels, each made of two antenna elements. The results show that using compressed elements in designing this coil provides a desired recursive factor (isolation better than 35dB), while coupling is kept less than 60dB between non-adjacent elements. In this report, the structure coupling effects include mutual effects of coil elements, resources, and phantom. The obtained results of the magnetic field homogeneity, bandwidth, and specific absorption rate are also evaluated. The results show that the bandwidth, the SAR for the 1w input power, and the $B_{1}^{-}$ homogeneity distribution are 1.1%, 0.07969W/kg, and 84%, respectively. To present this coil for a brain imaging, elements miniaturization is done where the elements size has been decreased in design.
Gain Enhancement of a Millimeter Wave Antenna using Stacked Dielectric-Slabs Superstrate

This paper presents a technique of gain enhancement using stacked dielectric slabs atop a microstrip patch antenna for 28-GHz application. A microstrip patch antenna (MPA) is designed at 28-GHz and loaded with eight 15 × 15mm2 dielectric slabs supported by seven 10 × 10mm2 dielectric slabs in the center. This arrangement of dielectric slabs enhances the gain of MPA by 4.1 dB when loaded very close to the antenna without affecting its input reflection coefficient. The prototype antenna is tested for radiation performance and its observed that the measured and simulated results are in good agreement.
Normally-Off InAlN/GaN Fin-MOSHEMT with Fluorine Treatment

GaN-based HEMTs feature a lot of superior material properties, including high electron mobility, wide band-gap, and large breakdown field. These properties are very suitable for power electronic applications. However, due to the high two dimensional electron gas (2DEG) density, a conventional GaN HEMT is an inherently normally-on device. Considering safety design in the power electronic systems, high performance normally-off GaN HEMT s are needed [1] . FinFet (tri-gate) structure has recently been applied to GaN HEMTs for the normally-off operation. However, a conventional FinFet (tri-gate) GaN HEMT requires very small channel widths to achieve the normally-off operation. This needs very critical process conditions and could cause the on-resistance (R on ) to be obviouslhy degraded [2] . In this study, an InAlN/GaN fin-MOSHEMT combined with fluorine treatment is demonstrated. It doesn’t require very small channel widths to achieve a normally-off HEMT while having excellent performances.
Novel Dichroic Subreflector Design for Cassegrain Antennas

Novel subreflector design for Dual Band Cassegrain Antenna systems was proposed in this paper. Proposed Frequency Selective subreflector, reflecting frequencies in X Band and transmitting in S-Band was designed and manufactured using the Selective Laser Sintering method. Tests were made both on the manufactured unit and on a complete antenna system using GEO satellite beacon signals. It was shown that total antenna efficiencies in both frequency bands using Frequency Selective Surface dichroic subreflector were more than 65 %.
A nesting approach for the numerical analysis of MRI birdcage antennas in the presence of the human head

Integral-equation approaches are among the solvers that can be used to analyse RF fields in MRI scanners, in particular when the human body is divided into a collection of homogeneous objects. This solver can be relatively intensive in terms of computation time and memory if the full solution is rerun everytime minor changes are considered in the MRI antennas. In this work, an efficient solving tool based on a nesting approach is proposed. The idea consists of avoiding recomputation of all the equivalent currents inside the body. A validation is provided for a simple structure with a commercial solver (CST); then by using a developed in-house code, the magnetic field inside the brain is shown when a birdcage antenna is used around the human head.
Regulation of growth and toxicity of a mixotrophic microbe: implications for understanding range expansion in Prymnesium parvum

Abstract: The rapid range expansion of the toxigenic marine haptophytic alga Prymnesium parvum in inland aquatic systems across the southern USA and beyond has prompted great interest in the ecology and evolutionary biology of this invasive bloom-forming species. Researchers have speculated that increased toxicity and heterotrophy in suboptimal environments allow blooms to develop in these new inland habitats that seem to represent extremes relative to P. parvum's perceived optimal niche. We used a laboratory-based study to elucidate the roles of salinity and nutrient availabilities in P. parvum growth and toxicity under environmental conditions representative of hypereutrophic reservoirs of the southwestern USA in which P. parvum blooms are now common. We found evidence that nutrient conditions favoring toxigenesis in P. parvum are suboptimal for growth and bloom formation, whereas conditions conducive to high growth rates are less favorable for toxigenesis. In contrast, both growth and toxicity scaled positively with salinity. Taken in the context of the documented biogeography of P. parvum and that toxigenesis in P. parvum probably evolved in support of heterotrophic nutrient acquisition, our results suggest that P. parvum's apparent range expansion into and across the USA is driven by increasing availabilities of salty and nutrient-rich systems, rather than by its toxigenic abilities.
