An Ultrawideband and Dual-Beam Scanning Array Antenna Charactered by Coding Method

We report an ultrawideband array antenna charactered by coding method. The Vivaldi antenna is chosen as radiating element and the array antenna is fed by a 1 to 8 ultrawideband power divider network. The desired coding states are realized by position reverse of the feeding ports and the power divider network is matched by loading three optimized stepped circuited stubs. A prototype was fabricated and measured and the results show the working bandwidth is approximately 85.7% (from 4 to 10 GHz). More importantly, accurate dual-beam frequency scanning feature is demonstrated and the scanning angle ranges from 21° to 54° (–21° to –54°) when the frequency changes from 4 to 9 GHz. Also, the 3 dB gain bandwidth is ultrawide, from 4 to 10 GHz. The measured results agree well with the simulated ones. Such an ultrawideband array antenna is expected to have potential applications in near future.
Isolation and Identification of Bacterial Species Associated with Non- Biting Flies in Egypt

Thirteen different species of bacteria were isolated and identified from the external body surface of Musca domestica collected from carrions and garbage dumps at Al Mansoureya, Giza, Egypt. The identified bacteria species were season and habitat dependent. The most frequent bacteria isolated from house flies collected from carrion or garbage in all seasons were Staphylococcus spp. and Esherichia coli. The total count of bacteria species was higher in summer season than in other seasons. Also, this count was higher on flies collected from carrion than on flies collected from garbage dumps. Chrysomya albiceps flies carried (11) different bacterial species on their external body surface all over the four seasons. Bacteria species were season and habitat dependent. The most frequent bacteria isolated from C. albiceps flies collected from carrion or garbage dumps in all seasons were Staph.spp. The highest total bacterial count was recorded during spring season for bacteria isolated from Chrysomya flies collected from carrion. Four different bacterial species were identified on the external body surface of Sarcophaga carnaria in autumn 2014. The most frequent bacteria species isolated were Staphylococcus spp. Three different bacterial species were identified on the external body surface of Lucilia sericata in autumn 2014. The most frequent bacteria species was Staph. spp. In general, 36 bacterial isolates from the different flies tested were identified. Bacteria species isolated from the external body surface of C. albiceps, S. carnaria and L. sericata were identified for the first time. The highest number of bacteria species (13) were isolated from M. domestica followed by (11) species from C. albiceps.
A 10-MHz Closed-Loop EMI-Regulated GaN Switching Power Converter Using Emulated Miller Plateau Tracking and Adaptive Strength Gate Driving

There has been a classic design trade-off between electromagnetic interference (EMI) and power efficiency in switching power circuits historically. This work explores the technical strategies that well balance this trade-off. In particular, an emulated Miller plateau tracking scheme is proposed to identify critical <italic>di</italic>/<italic>dt</italic> and <italic>dv</italic>/<italic>dt</italic> instants, which are susceptible to load current and power input voltage conditions. An adaptive strength gate driving scheme facilitates low <italic>di</italic>/<italic>dt</italic> and high <italic>dv</italic>/<italic>dt</italic> switching operation, which leads to the targeted EMI and switching loss optimization. A switching power converter IC prototype was implemented in a 0.35-<inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula> high-voltage (HV) Bipolar-CMOS-DMOS (BCD) process. Operating at 10 MHz, the converter regulates an output at 5 V with 6-W power range, accommodating a wide input supply voltage ranging from 5 to 40 V. It achieves above 70% efficiency over 95.8% of the full power range, with a peak efficiency of 81.4% at 1.25 W. With the proposed strategies, the peak EMI of the converter is reduced by 19.23 dB<inline-formula> <tex-math notation="LaTeX">$\mu \text{V}$ </tex-math></inline-formula> in Band B (< 30 MHz) and 9 dB<inline-formula> <tex-math notation="LaTeX">$\mu \text{V}$ </tex-math></inline-formula> in Band C/D (>30 MHz), with only 2.44% efficiency penalty.
Neural circuit basis of aversive odour processing in Drosophila from sensory input to descending output

Evolution has shaped nervous systems to produce stereotyped behavioural responses to ethologically relevant stimuli. For example when laying eggs, female Drosophila avoid geosmin, an odorant produced by toxic moulds. Here we identify second, third, and fourth order neurons required for this innate olfactory aversion. Connectomics data place these neurons in a complete synaptic circuit from sensory input to descending output. We find multiple levels of valence-specific convergence, including a novel form of axo-axonic input onto second order neurons conveying another danger signal, the pheromone of parasitoid wasps. However, we also observe extensive divergence: second order geosmin neurons connect with a diverse array of 80 third order cell types. We find a pattern of convergence of aversive odour channels at this level. Crossing one more synaptic layer, we identified descending neurons critical for egg-laying aversion. Our data suggest a transition from a labelled line organisation in the periphery to a highly distributed central brain representation that is then coupled to distinct descending pathways.
Integrated 5G-Satellite Networks: A Perspective on Physical Layer Reliability and Security

Fifth generation (5G) mobile systems are expected to be integrated with different radio access methods such as satellite components to provide seamless connectivity and ubiquitous coverage for users worldwide. In this article, we first provide a brief review of current initiatives and system architecture for the convergence of satellite and 5G networks. Then, we investigate various approaches to improve reliability or security at the physical layer for the integrated 5G-satellite networks. An effective achievable rate is presented as the key performance indicator to measure the security and reliability trade-off, followed by the implementation of a proposed beamforming scheme. Finally, we present future trends and challenges in integrated 5G-satellite networks.
Ligand dependence of the electronic configuration of the rhodium-rhodium bond in Rh25+ complexes as studied by electon spin resonance and electrochemistry

Electron spin resonance spectra of Rh{sub 2}{sup 5+} radicals derived from Rh{sub 2}(O{sub 2}CCH{sub 3}){sub 4}L{sub 2}, where L is H{sub 2}O, CH{sub 3}OH, i-PrOH, THF, (CH{sub 3}){sub 2}CO, CH{sub 3}CN, and Cl{sup {minus}}, show abnormally large shifts of the principal values of their g tensors from the free-spin value. These large shifts indicate that the orbital angular momentum of the odd electron in these radicals is not quenched; namely the odd-electron orbital is degenerate. These observations show that a substitution of amidate or amidinate ligands for bridging carboxylates results in an enhanced destabilization of the {delta}{sub RhRh}* orbital. This destabilization should be induced by an increased mixing of ligand {pi} orbitals into the {delta}{sub RhRh}* orbital in a {pi}-antibonding phase between the Rh atom and the bridging ligand. An appreciable delocalization of the {sigma}{sub RhRh} orbital onto bridging ligands is also proposed in connection with a dependence of oxidation potentials on bridging ligands.
Effect of pre and post-partum Alphatocopherol supplementation on body measurements and its relationship with body condition, milk yield, and udder health of Jersey crossbred cows at tropical lower Gangetic region

To find out the effect of Alphatocopherol supplementation an experiment was carried out on Jersey crossbred cows at lower Gangetic region. Three groups were taken viz. C (without any supplementation), T1 (Alphatocopherol supplemented @ 1g/cow/day 30 days before and after calving) and T2 (Alphatocopherol supplemented @ 1g/cow/day 30 days before and 60 days after calving) and the effect of Alphatocopherol supplementation was seen for body measurements. Statistically analyzed data revealed that THT (cm) (tail head thickness) was T1 and T2 had significantly (P
2 impurities in the Haldane chain compound Y 2 BaNiO 5

We present the effect of Zn (S50) and Cu (S51/2) substitution at the Ni site of S51 Haldane chain compound Y2BaNiO5 . 89 Y nuclear-magnetic resonance ~NMR! allows us to measure the local magnetic susceptibility at different distances from the defects. The 89 Y NMR spectrum consists of one central peak and several less intense satellite peaks. The central peak represents the chain sites far from the defect. Its shift measures the uniform susceptibility, which displays a Haldane gap D’100 K and it corresponds to an antiferromagnetic ~AF! coupling J’260 K between the nearest neighbor Ni spins. Zn or Cu substitution does not affect the Haldane gap. The satellites, which are evenly distributed on the two sides of the central peak, probe the antiferromagnetic staggered magnetization near the substituted site. The spatial variation of the induced magnetization is found to decay exponentially from the impurity for both Zn and Cu for T.50 K. Its extension is found identical for both impurities and corresponds accurately to the correlation length j(T) determined by Monte Carlo simulations for the pure compound. In the case of nonmagnetic Zn, the temperature dependence of the induced magnetization is consistent with a Curie law with an ‘‘effective’’ spin S50.4 on each side of Zn. This staggered effect is quantitatively well accounted for in all the explored range by quantum Monte Carlo ~QMC! computations of the spinless-defect-induced magnetism. In the case of magnetic Cu, the similarity of the induced magnetism to the Zn case implies a weak coupling of the Cu spin to the nearest-neighbor Ni spins. The slight reduction of about 20230 % of the induced polarization with respect to Zn is reproduced by QMC computations by considering an antiferromagnetic coupling of strength J850.1J20. 2J between the S51/2 Cu spin and nearest-neighbor Ni spin. Macroscopic susceptibility measurements confirm these results as they display a clear Curie contribution due to the impurities nearly proportional to their concentration. This contribution is indeed close to that of two spin half for Zn substitution. The Curie contribution is smaller in the Cu case, which confirms that the coupling between Cu and near-neighbor Ni is antiferromagnetic.
Re-purposing Ac/Ds transgenic system for CRISPR/dCas9 modulation of enhancers and non-coding RNAs in zebrafish

Due to its genetic amenability coupled with recent advances in genome editing, the zebrafish serves as an excellent model to examine the function of both coding and non-coding elements. Recently, the non-coding genome has gained prominence due to its critical role in development and disease. Here, we have re-purposed the Ac/Ds maize transposition system to reliably screen and efficiently characterise zebrafish enhancers, with or without germline propagation. We further utilised the system to stably express guide RNAs in microinjected embryos enabling tissue-specific CRISPR/dCas9-interference (CRISPRi) knockdown of lncRNA and enhancer activity without disrupting the underlying genetic sequence. Our study highlights the utility of Ac/Ds transposition for transient epigenome modulation of non-coding elements in zebrafish. Summary statement We adapted the Ac/Ds transposition system, which enables continuous expression of guide RNAs for CRISPR/dCas9 perturbation, to examine the function of non-coding RNAs and enhancer elements in zebrafish.

Applying entrapped mixed microbial cell techniques for biological wastewater treatment

The entrapment of mixed microbial cell was accomplished by using a porous material, such as cellulose triacetate, to confine the migration of microorganism. Synthetic glucose, phenol, carbaryl and nitrate wastewater was used as substrate to evaluate this process. Applying entrapped microbial cell techniques for biological water/wastewater treatment was previously investigated mainly by using the pure culture system. For the past six years, the University of Hawaii has investigated this technology for biological wastewater treatment by using a mixed culture approach. It was found that the developed carrier, using cellulose triacetate, is the most suitable for providing the necessary mechanical strength and durability under both the aerobic and anaerobic conditions. It also provides many advantages, such as a short start-up period, high effluent quality in terms of COD, NO3-N concentrations and removal efficiency, low effluent suspended solid concentration, and high SRT with low HRT. The process has potential to replace or upgrade the existing biological processes for water and wastewater treatment. A pre-engineered and packaged plant can be easily developed for a small wastewater treatment system for toxic or hazardous wastewater.
Improved Magnetic Guidance Approach for Automated Guided Vehicles by Error Analysis and Prior Knowledge

Navigation accuracy and robustness are key performance indexes of automated guided vehicles (AGVs). In our previous study, the magnetic guidance approach based on magnetic dipole model and non-linear optimization algorithm was proposed, which has high positioning accuracy and could estimate the yaw angle of AGV directly. However, the localization accuracy of the magnetic guidance approach will deteriorate if the magnetic nails (MNs) buried in the ground have installation errors or the magnetic moments between the MNs are inconsistent. To overcome this problem, we propose an improved method based on error analysis and prior knowledge for the magnetic guidance approach. Firstly, the factors that affect the localization accuracy are analyzed, and the parameters (<inline-formula> <tex-math notation="LaTeX">$B_{\mathrm {T}}$ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$p$ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$c$ </tex-math></inline-formula>), whose errors will deteriorate the localization accuracy, are combined with MN pose (<inline-formula> <tex-math notation="LaTeX">$a$ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$b$ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$m$ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$n$ </tex-math></inline-formula>) as optimization variables. Then, the prior knowledge regarding (<inline-formula> <tex-math notation="LaTeX">$B_{\mathbf {T}}$ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$p$ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$c$ </tex-math></inline-formula>) is employed to construct the constraint conditions for the magnetic guidance approach. Finally, the global convergence probability and convergence speed of the improved magnetic guidance approach are analyzed. Experimental results demonstrate the adaptability and robustness of the improved magnetic tracking approach, which diminishes the impact of MN installation errors and magnetic moment deviation. The parking accuracy of AGV is improved to 1.42±0.85 mm and 1.10±0.38°.
Morpho-agronomic characterization of genotypes of Conilon coffee intercropped with dwarf coconut palms

The study of Coffea canephora genotypes at different environments, and the various edaphoclimatic characteristics and techniques used in the cropping systems is an important tool in the process of identifying those with higher adaptability to a particular scenario. The objective of this study was to characterize the development of Conilon coffee genotypes in an intercropping system with dwarf coconut palms. The experiment was carried out in the municipality of Colatina (Espírito Santo, Brazil), studying agronomic traits of genotypes of Conilon coffee in a completely randomized design and six repetitions. The eight treatments were composed by eight Brazilian improved genotypes of Conilon coffee and traits of growth, leafiness and fruit bearing were measured. It was possible to verify different behaviors among genotypes regarding tree architecture and fruit production. The genotypes 83 and 48 presented higher number of fruits per branch, besides vigorous growth, along with genotype 153 which presented larger leaves and higher content of chlorophyll b. Genotype 02 also had higher chlorophyll b content, but did not develop large leaves. The genotypes 16 and 100 presented lower levels of chlorophyll b but greater leaf development. Genotypes 03 and 76 are characterized by lower harvest yield. The biomass and the number of fruits per plagiotropic branch seem to be especially useful to study the variability and may ease future studies of variability among genotypes in intercropping systems.

Apical extrusion of root canal filling material during the removal of gutta-percha and resilon

Introduction. Root canal filling material may be extruded during retreatment through the apical foramen and cause flare-up or chronic infection. The aim of this study was to compare the apical extrusion of gutta-percha and resilon filling materials during retreatment using hand and rotary instruments. Methods. Sixty extracted single-rooted teeth with single, straight canal were selected. Canals were prepared with ProTaper Universal rotary system to a size F2. Two groups (30 teeth in each) were filled with gutta-percha or resilon points, respectively. In both groups teeth were randomly divided into the three subgroups (10 teeth in each), based on the instruments used for retreatment: Hedstrom hand files and two rotary groups- ProTaper and Twisted File instruments. Apical extrusion was detected visually, using a 4-degree scoring system. Mean scores were calculated and analyzed statistically (t-test and ANOVA). The level of significance was set at p < 0.05. Results. Under tested experimental conditions, the type of canal filling material did not have significant effect on the results of apical extrusion during retreatment. Significantly more material was extruded in the resilon group when manual, Hedstrom file was used (1.80 ? 1.13) than rotary ProTaper (0.60 ? 0.70) and Twisted File (0.50 ? 0.71). Conclusions. The use of a rotary technique is recomended to minimize apical extrusion, especially when resilon obturation material is removed during retreatment.
Search for Superheavy Elements in Uranium Irradiated with High-Energy Protons

The recent reports of M A R I N O V et al. [1] on the possible production of eka-mercury (Z = 112) in tungsten targets bombarded with 24 GeV protons, have lead many experimenters [2] to initiate similar searches for superheavy elements in beam-stop targets of highenergy particle accelerators. In one of these investigations, a 72 g uranium target was irradiated with 4 Χ 10 protons at 24 GeV/c in an external beam of the CERN proton synchroton. The bombarded target was subjected to vacuum distillation at 1400 °C by a CERNOrsay-Heidelberg collaboration [3] searching for superheavy elements in the volatile fraction. From the residue, after dissolving it in nitric acid, W O L F et al. [4] volatilized osmium, extracted the uranium into tributyl-phosphate (TBP) and separated a lanthanide fraction, looking for eka-osmium and transuranium actinides, respectively. After these operations, two liquid samples remained.
Increasing temperatures, diversity loss and reorganization of deep-sea fish communities east of Greenland

In recent years, Arctic and sub-Arctic fish communities have shown extensive re organization on shelves and in shallow waters, but little is known about the ecological impact of environmental changes in deeper waters. We examined temporal changes (1998−2016) in fish diversity and community structure based on research survey data from East Greenland, over a depth gradient spanning 400 to 1500 m. A northern and a southern continental slope region, 360 km apart, were analysed for temporal changes in water temperature and fish community structure. The bottom water temperature increased by up to 0.2 and 0.5°C, respectively. Contrary to expectations, there was a concomitant loss of species richness of up to 3 and 5 species, respectively, and a decrease in total abundance in both regions. Abundances of individual species displayed different trends between regions, with 3 species of wolf fishes (Anarhichas spp.) and American plaice Hippoglossoides platessoides decreasing in the north and blue antimora Anti mora rostrata, Agassiz’ slickhead Alepocephalus agassizii and the roundnose grenadier Cory phae no ides rupestris decreasing in the south. The regional differences may reflect different oceanographic characteristics, as the northern region is more influenced by colder Arctic water, whereas the southern region is primarily influenced by the Subpolar Gyre (SPG). However, the observed temperature increase is expected to be due to an intensifying Atlantic Multidecadal Oscillation and/or anthropogenic climate change and not to SPG changes. The observed changes in biodiversity and community structure associated with warming are likely to affect community dynamics and alter ecosystem functioning.
