Gain enhancement of implanted antenna using lens and parasitic ring
Authors: Alamri S. , AlAmoudi A. , Langley R.
Published: March 2016

This Letter presents methods for improving the gain and efficiency of a microstrip patch antenna operating at 2.45 GHz implanted in the fat layer of the human body. Simulations using CST Microwave Studio are verified by measurements carried out in an anechoic chamber using a cut of fresh pork meat which has close electromagnetic characteristics to the human body. Using a glass lens and a parasitic ring placed on the skin the implanted antenna gain can be enhanced by almost 8.5 dB.

Multi‐class classification using kernel density estimation on K‐nearest neighbours
Authors: Tang Xiaofeng , Xu Aiqiang
Published: March 2016

A fast and accurate multi‐class classification method based on the conventional kernel density estimation (KDE) and K‐nearest neighbour (KNN) techniques is proposed. This method estimates the cumulative probabilities of the test sample on its KNNs which may belong to different classes, then selects the maximum weighted class as the classification result. Experiments are carried out to diagnose multiple parametric faults in an analogue circuit, and the classification performances of the proposed method as well as KNN, KDE and support vector machine are compared with each other in detail. The results show that the proposed method is generally better than the other methods not only in classification accuracy but also in test speed, and is promising for practical use.
Wireless power transfer using a field‐enhancing coil and a small‐sized receiver with low coupling coefficient
Authors: Mao Shitong , Zhang Jiantao , Song Kai , Wei Guo , Zhu Chunbo
Published: March 2016

This study investigates the near‐field wireless power transfer system with small‐sized receiver. The receiver is placed at a relatively long distance from the power emitter. The coupling between the receiver and the emitter is very weak, which results in low‐power delivery and efficiency. A passive resonance coil, which enhances the field, is added to the emitter to address these problems. The necessary coupled‐mode theory is developed and combined with optimal operation of the class‐E amplifier. The impact of the enhancing coil (EX) on the energy distribution is discussed from the perspective of energy amplification between the source coil and the EX. The point of the maximum energy of the EX is found and necessary conditions for improving transfer efficiency of such structure are proposed. An experimental setup operating at a frequency of 300 kHz was built using the EX concept. The maximum secondary magnetic field generated by the EX was established and used to wirelessly power a 4 cm receiver with more than 40 mW at 0.5 m. The structure is also compared with a similar system without an EX. Test results show that the inclusion of the EX in the emitter strengthens the spatial magnetic field and improves the transmission efficiency.
Assessing the impacts of photovoltaic penetration across an entire low‐voltage distribution network containing 1.5 million customers
Authors: Westacott Paul , Candelise Chiara
Published: March 2016

Deployment of grid‐connected photovoltaics (PV) in the UK has increased rapidly. By 2014 there were over 650,000 installations (over 5 GWp), spread over different market segments (on site of existing domestic and non‐domestic electricity demand customers, or connected directly to the network, e.g. solar farms). This rapid deployment and diverse market segmentation raises questions about impacts upon the electricity network. Here the authors present a novel geographical information system framework which maps current PV deployment and electricity demand to sensitive spatial resolution and by market segment. This is used to understand how current PV deployment affects power flows between the high‐voltage (HV) and low‐voltage (LV) network. The analysis reveals that overall, current LV PV generation is significantly below summer daytime LV demand – with over half of the areas investigated showing electricity demand five times greater than peak PV generation. Interestingly a small number of areas exhibit peak PV generation greater than demand, where reverse power flow from LV to HV may occur. The framework is hence capable of identifying the areas where network impacts are likely to occur and will also be useful to consider how integration strategies, such as energy storage and demand response could facilitate further PV deployment.
Influence of reducing reagent combination in graphene oxide reduction
Authors: Hu Chengyuan , Zhou Rong , Fan Chuanjie , Zhou Xiaodong
Published: March 2016

Large‐scale production of high‐quality graphene nanosheets has been considered to be an interesting and significant challenge. A new approach is reported regarding the fabrication of high‐quality graphene nanosheets via chemical reduction with the combination of reducing reagents from graphene oxide (GO). High‐conducting reduced GO (RGO) was provided with the combination of hydrazine hydrate and hydroiodic acid. RGO was characterised by X‐ray diffraction, Fourier‐transform infrared spectroscopy, X‐ray photoelectron spectroscopy, Raman, thermo gravimetric analysis, atomic force microscopy and four‐probe conductivity tester. Characterisation results indicated that oxygenated functional groups were removed from GO, and high graphitisation has occurred in GO reduction process. The electrical conductivity of RGO was considerably improved and the C/O ratio of RGO was higher than that prepared by single reducing reagent. Combination of hydrate hydrazine and hydroiodic acid have showed high reduction efficiency and good synergistic effect in GO reduction process. The findings in this work can promote research on prepared graphene‐based nanosheets composites by a quick and effective processing technique.
Preoperative Planning of Virtual Osteotomies Followed by Fabrication of Patient Specific Reconstruction Plate for Secondary Correction and Fixation of Displaced Bilateral Mandibular Body Fracture
Authors: Thor Andreas
Published: March 2016

This paper describes the course of treatment of a severely diplaced bilateral mandibular body fracture, where the first osteosynthesis failed. The subject developed an open bite due to a posterior rotation of the distal part of the mandible and anterior rotation of the proximal parts of the mandible. This situation was evaluated with CBCT and the facial skeleton was segmented using computer software. Correct occlusion was virtually established by bilateral virtual osteotomies in the fracture areas of the mandible. After segmentation, the mandible was virtually rotated back into position and the open bite was closed. A patient specific mandibular reconstruction plate was outlined and fabricated from the new virtual situation and the plate was thereafter installed utilizing the preoperative plan. Osteotomy- and drill-guides was used and thus simplified the surgery resulting in uneventful healing. Virtual planning and patient specific implants and guides were valuable in this case of secondary reconstructive trauma surgery.

Quantum field theory on curved spacetimes: Axiomatic framework and examples
Authors: Fredenhagen Klaus , Rejzner Kasia
Published: March 2016

In this review article, we want to expose a systematic development of quantum field theory on curved spacetimes. The leading principle is the emphasis on local properties. It turns out that this requires a reformulation of the QFT framework which also yields a new perspective for the theories on Minkowski space. The aim of the present work is to provide an almost self-contained introduction into the framework, which should be accessible for both mathematical physicists and mathematicians.
Dispersion of nanoscale oxides in MnSi1.73 fabricated by solid state reaction and pulsed electric current sintering
Authors: Homma Tomoyuki , Mima Hirotaka , Nanko Makoto , Takeda Masatoshi
Published: March 2016

We have investigated a relationship between the fabrication process and the resultant crystal structure of a MnSi1.73 thermoelectric material in order to understand the effect of microstructures on the thermoelectric properties. Local crystal structure of the matrix phase is identified as a modulated Mn15Si26 phase based on the Ye and Amelinckx method [J. Solid State Chem. 61, 8 (1986)]. The Mn15Si26 phase is a degenerate semiconductor showing metal like behavior. In addition, nanoscale SiO2 particles are dispersed. The crystal structure of SiO2 is amorphous, and the SiO2 particles reduce thermal conductivity because of its inherent characteristic. A relatively high figure of merit of 0.38 is obtained, resulting from the multiple microstructures of Mn15Si26 and SiO2.
Effects of inner materials on the sensitivity and phase depth of wireless inductive pressure sensors for monitoring intraocular pressure
Authors: Jang Cheol-In , Shin Kyeong-Sik , Kim Mi Jeung , Yun Kwang-Seok , Park Ki Ho , Kang Ji Yoon , Lee Soo Hyun
Published: March 2016

In this research, we developed wireless, inductive, pressure sensors with high sensitivity and investigated the effects of the inner materials (copper or ferrite) on the performance of the sensors. The proposed sensor is comprised of two parts, i.e., the top and the bottom parts. The top part includes a micro coil and a capacitor for the wireless transfer of data, and the bottom part includes the inner materials and a thick or thin flexible membrane to induce changes in the inductance. An anchor is used to assemble the top and bottom parts. The behavior of the sensor with copper was based on the eddy current effect, and, as the pressure increased, its resonance frequency increased, while its phase depth decreased exponentially. The principle of the sensor with ferrite was related to the effective permeability between a ferrite and a coil, and its response was the opposite of that with copper, i.e., as the pressure increased, the resonance frequency decreased linearly, and the phase depth increased linearly. These different operational mechanisms can be explained by the changes in the equations of inductance presented in this paper. After characterizing four different types of inductive pressure sensors in ambient air, one type of inductive pressure sensor was used to monitor the intraocular pressure (IOP) of a rabbit's eye as a biomedical application. The results showed that, in the animal tests, the measured responsivity and sensitivity were 16.7 kHz/mmHg and 1340 ppm/mmHg, respectively. These data indicate that the proposed sensor is a good candidate for monitoring IOP.
Influence of emitter temperature on the energy deposition in a low-pressure plasma
Authors: Levko Dmitry , Raja Laxminarayan L.
Published: March 2016

The influence of emitter temperature on the energy deposition into low-pressure plasma is studied by the self-consistent one-dimensional Particle-in-Cell Monte Carlo Collisions model. Depending on the emitter temperature, different modes of discharge operation are obtained. The mode type depends on the plasma frequency and does not depend on the ratio between the densities of beam and plasma electrons. Namely, plasma is stable when the plasma frequency is small. For this plasma, the energy transfer from emitted electrons to plasma electrons is inefficient. The increase in the plasma frequency results first in the excitation of two-stream electron instability. However, since the thermal velocity of plasma electrons is smaller than the electrostatic wave velocity, the resonant wave-particle interaction is inefficient for the energy deposition into the plasma. Further increase in the plasma frequency leads to the distortion of beam of emitted electrons. Then, the electrostatic wave generated due to two-stream instability decays into multiple slower waves. Phase velocities of these waves are comparable with the thermal velocity of plasma electrons which makes possible the resonant wave-particle interaction. This results in the efficient energy deposition from emitted electrons into the plasma.
Acoustic spin pumping in magnetoelectric bulk acoustic wave resonator
Authors: Polzikova N. I. , Alekseev S. G. , Pyataikin I. I. , Kotelyanskii I. M. , Luzanov V. A. , Orlov A. P.
Published: March 2016

We present the generation and detection of spin currents by using magnetoelastic resonance excitation in a magnetoelectric composite high overtone bulk acoustic wave (BAW) resonator (HBAR) formed by a Al-ZnO-Al-GGG-YIG-Pt structure. Transversal BAW drives magnetization oscillations in YIG film at a given resonant magnetic field, and the resonant magneto-elastic coupling establishes the spin-current generation at the Pt/YIG interface. Due to the inverse spin Hall effect (ISHE) this BAW-driven spin current is converted to a dc voltage in the Pt layer. The dependence of the measured voltage both on magnetic field and frequency has a resonant character. The voltage is determined by the acoustic power in HBAR and changes its sign upon magnetic field reversal. We compare the experimentally observed amplitudes of the ISHE electrical field achieved by our method and other approaches to spin current generation that use surface acoustic waves and microwave resonators for ferromagnetic resonance excitation, with the theoretically expected values.
The significant role of covalency in determining the ground state of cobalt phthalocyanines molecule
Authors: Zhou Jing , Zhang Linjuan , Hu Zhiwei , Kuo Changyang , Liu Hengjie , Lin Xiao , Wang Yu , Pi Tun-Wen , Wang Jianqiang , Zhang Shuo
Published: March 2016

To shed some light on the metal 3d ground state configuration of cobalt phthalocyanines system, so far in debate, we present an investigation by X-ray absorption spectroscopy (XAS) at Co L2,3 edge and theoretical calculation. The density functional theory calculations reveal highly anisotropic covalent bond between central cobalt ion and nitrogen ligands, with the dominant σ donor accompanied by weak π-back acceptor interaction. Our combined experimental and theoretical study on the Co-L2,3 XAS spectra demonstrate a robust ground state of 2A1g symmetry that is built from 73% 3d7 character and 27% 3d8L¯ (L¯ denotes a ligand hole) components, as the first excited-state with 2Eg symmetry lies about 158 meV higher in energy. The effect of anisotropic and isotropic covalency on the ground state was also calculated and the results indicate that the ground state with 2A1g symmetry is robust in a large range of anisotropic covalent strength while a transition of ground state from 2A1g to 2Eg configuration when isotropic covalent strength increases to a certain extent. Here, we address a significant anisotropic covalent effect of short Co(II)-N bond on the ground state and suggest that it should be taken into account in determining the ground state of analogous cobalt complexes.
Thienyl Difluoroboron β-Diketonates in Solution and Polylactide Media
Authors: Kolpaczynska Milena , DeRosa Christopher A. , Morris William A. , Fraser Cassandra L.
Published: March 2016

Difluoroboron β-diketonates (BF2bdks) have impressive optical properties in both solution and the solid state. In particular, both fluorescence and room-temperature phosphorescence are present when the dyes are confined to a rigid matrix, such as poly(lactic acid) (PLA). To expand the current knowledge and colour range capabilities of this unique type of multi-emitting chromophore, a series of thienyl-substituted BF2bdk complexes have been synthesized. The photophysical properties were investigated in dichloromethane solution and in the solid state as dye/PLA blends. By varying donor ability, i.e. methyl, phenyl, methoxy, and thienyl substituents, and by changing the dye loading in the PLA media (0.1–10 % dye loading) red-shifted emission was achieved, which is important for biological imaging applications. In dilute CH2Cl2 solution, complexes exhibited absorptions ranging from 350 to 420 nm, solid-state fluorescence in PLA ranging from 390 to 500 nm, and oxygen sensitive phosphorescence ranging from 540 to 585 nm in PLA blends. Promising candidates as dye/PLA blends serve as models for dye–polymer conjugates for application as biological oxygen nanoprobes.
An initial typology of contexts of dyadic sexual encounters between men and associations with sexual risk and pleasure: findings from an observational study

Published: March 2016

Background
Although many within-subjects comparisons conducted on samples of men who have sex with men have sought to understand the association between specific situational characteristics (e.g. drug use or location of sex) and sexual risk behaviour, none have considered the ‘clustering’ of patterns of situational characteristics. An initial typology of sexual encounters is derived and the relationship of this typology to condomless anal intercourse (CAI) and pleasure is tested. Methods: Data from a longitudinal survey of men who have sex with men living in England were used. Multilevel latent class analyses were estimated to determine an optimal class solution on the situational characteristics, and then pseudo-imputation was used to estimate the association between class and both CAI and pleasure. Results: A three-class solution fit the data best, with a scaled relative entropy of 92.4%. Classes were characterised as featuring: regular steady partners in private locations with low drug use (class 1), casual partners with increased probability of sex occurring in a sex-on-premises venue (class 2), and high levels of polydrug use together with increased probability of casual partners (class 3). Encounters were different both in pairwise comparisons and overall on probability of CAI. They were different overall but not necessarily pairwise on pleasure. Conclusions: These initial findings demonstrate the possibility of understanding sexual encounters in terms of the contexts, or classes, within which they occur. This may have implications for tailoring HIV prevention to specific encounter types. Future research should seek to extend encounter-level typologies to specific drug use variables.
Cell-to-cell movement of mitochondria in plants

Significance

We report cell-to-cell movement of mitochondria through a graft junction of two tobacco species,
Nicotiana tabacum
and
Nicotiana sylvestris
. The flowers of the
N. tabacum
line we used are male sterile due to a sterility-causing mitochondrial genome, whereas the
N. sylvestris
flowers are fertile. Grafting created an opportunity for organelle movement during the healing process when cell-to-cell connections at the graft junction were restored. We recognized
N. sylvestris
mitochondrial DNA transfer by restoration of fertile flower anatomy in plants regenerated from graft junctions. Demonstrating cell-to-cell movement of mitochondria reconstructs the evolutionary process of horizontal mitochondrial DNA transfer and enables modification of mitochondria by DNA acquired from other species.

Significance

Nasopharyngeal carcinoma (NPC) is a valuable cancer model to study the interaction of host genetics, viral infection, and environment in tumorigenesis. Little is known about the genetic basis for the remarkably distinct geographical distribution of NPC. We used a whole-exome sequencing approach to identify the genetic alterations associated with NPC susceptibility and revealed a strong link between macrophage-stimulating 1 receptor (
MST1R
) and NPC early-age onset (age of ≤20 y). MST1R is critical for innate immunity and plays an important role for host defense against viral infection. We further discovered that an interaction network involved in the MST1R/14-3-3 complex was frequently deregulated by genetic alterations in NPC. Our findings provide new insights in the pathogenesis of NPC by highlighting the involvement of the MST1R-mediated signaling pathways.

Time-variable gravity fields derived from GPS tracking of Swarm

Published: March 2016

Since 2002 Gravity Recovery and Climate Experiment (GRACE) provides monthly gravity fields from K-band ranging (KBR) between two GRACE satellites. These KBR gravity monthlies have enabled the global observation of time-varying Earth mass signal at a regional scale (about 400 km resolution). Apart from KBR, monthly gravity solutions can be computed from onboard GPS data. The newly reprocessed GPS monthlies from 13 yr of GRACE data are shown to yield correct time-variable gravity signal (seasonality, trends, interannual variations) at a spatial resolution of 1300 km (harmonic degree 15). We show that GPS fields from new Swarm mission are of similar quality as GRACE GPS monthlies. Thus, Swarm GPS monthlies represent new and independent source of information on time-variable gravity, and, although with lower resolution and accuracy, they can be used for its monitoring, particularly if GRACE KBR/GPS data become unavailable before GRACE Follow-On is launched (2017 August).

Objectives:

Biliary atresia (BA) is an idiopathic neonatal liver disease, characterized by inflammatory and fibrotic obliteration of extrahepatic bile ducts. Therefore, reliable methods for noninvasive diagnosis are needed. The present study aimed to analyze circulating microRNAs (miRNAs) in patients with BA using next‐generation sequencing for identifying novel diagnostic biomarkers.

Methods:

An initial screening of miRNAs in plasma from patients with BA and healthy controls (HCs) was performed on an Illumina next‐generation sequencing platform. Differential miRNAs were validated by quantitative real‐time polymerase chain reaction (qPCR). Target genes and related signal transduction pathways of differential miRNAs were predicted by online software.

Results:

In total, 146 differential miRNAs were identified by deep sequencing. Fifteen miRNAs with read counts >1000, that included 7 upregulated and 8 downregulated miRNAs, were predicted to be associated with liver fibrosis, biliary differentiation, and bile duct development. Of these, 6 miRNAs with read counts >5000 were analyzed by qPCR on an independent sample set comprising 44 patients with BA, 20 cholestatic disease controls, and 20 HCs. Two upregulated miRNAs (miR‐122‐5p, miR‐100‐5p) and 2 downregulated miRNAs (miR‐140‐3p, miR‐126‐3p) were confirmed by individual qPCR. Only miR‐140‐3p was significantly different from controls (P < 0.05), yielding an area under receiver operating characteristic curve of 0.75 with sensitivity of 66.7% and specificity of 79.1% at optimal threshold.

Conclusions:

Our findings indicate that patients with BA exhibit a distinct profile of circulating miRNAs and that plasma miR‐140‐3p may be a promising diagnostic biomarker for this disease.

Fast multidimensional ensemble empirical mode decomposition for the analysis of big spatio-temporal datasets
Authors: Wu Zhaohua , Feng Jiaxin , Qiao Fangli , Tan Zhe-Min
Published: March 2016

In this big data era, it is more urgent than ever to solve two major issues: (i) fast data transmission methods that can facilitate access to data from non-local sources and (ii) fast and efficient data analysis methods that can reveal the key information from the available data for particular purposes. Although approaches in different fields to address these two questions may differ significantly, the common part must involve data compression techniques and a fast algorithm. This paper introduces the recently developed adaptive and spatio-temporally local analysis method, namely the fast multidimensional ensemble empirical mode decomposition (MEEMD), for the analysis of a large spatio-temporal dataset. The original MEEMD uses ensemble empirical mode decomposition to decompose time series at each spatial grid and then pieces together the temporal–spatial evolution of climate variability and change on naturally separated timescales, which is computationally expensive. By taking advantage of the high efficiency of the expression using principal component analysis/empirical orthogonal function analysis for spatio-temporally coherent data, we design a lossy compression method for climate data to facilitate its non-local transmission. We also explain the basic principles behind the fast MEEMD through decomposing principal components instead of original grid-wise time series to speed up computation of MEEMD. Using a typical climate dataset as an example, we demonstrate that our newly designed methods can (i) compress data with a compression rate of one to two orders; and (ii) speed-up the MEEMD algorithm by one to two orders.
Adaptive multimode signal reconstruction from time–frequency representations
Authors: Meignen Sylvain , Oberlin Thomas , Depalle Philippe , Flandrin Patrick , McLaughlin Stephen
Published: March 2016

This paper discusses methods for the adaptive reconstruction of the modes of multicomponent AM–FM signals by their time–frequency (TF) representation derived from their short-time Fourier transform (STFT). The STFT of an AM–FM component or mode spreads the information relative to that mode in the TF plane around curves commonly calledridges. An alternative view is to consider a mode as a particular TF domain termed abasin of attraction. Here we discuss two new approaches to mode reconstruction. The first determines the ridge associated with a mode by considering the location where the direction of the reassignment vector sharply changes, the technique used to determine the basin of attraction being directly derived from that used for ridge extraction. A second uses the fact that the STFT of a signal is fully characterized by its zeros (and then the particular distribution of these zeros for Gaussian noise) to deduce an algorithm to compute the mode domains. For both techniques, mode reconstruction is then carried out by simply integrating the information inside these basins of attraction or domains.

Long chain polyunsaturated fatty acids (LCPUFA) are bioactive components of membrane phospholipids and serve as substrates for signaling molecules. LCPUFA can be obtained directly from animal foods or synthesized endogenously from 18 carbon precursors via theFADS2coded enzyme. Vegans rely almost exclusively on endogenous synthesis to generate LCPUFA and we hypothesized that an adaptive genetic polymorphism would confer advantage. The rs66698963 polymorphism, a 22 bp insertion-deletion withinFADS2, is associated with basalFADS1expression, and coordinated induction ofFADS1andFADS2 in vitro. Here we determined rs66698963 genotype frequencies from 234 individuals of a primarily vegetarian Indian population and 311 individuals from the U.S. A much higher I/I genotype frequency was found in Indians (68%) than in the U.S. (18%). Analysis using 1000 Genomes Project data confirmed our observation, revealing a global I/I genotype of 70% in South Asians, 53% in Africans, 29% in East Asians, and 17% in Europeans. Tests based on population divergence, site frequency spectrum and long-range haplotype consistently point to positive selection encompassing rs66698963 in South Asian, African and some East Asian populations. Basal plasma phospholipid arachidonic acid status was 8% greater in I/I compared to D/D individuals. The biochemical pathway product-precursor difference, arachidonic acid minus linoleic acid, was 31% and 13% greater for I/I and I/D compared to D/D, respectively. Our study is consistent with previousin vitrodata suggesting that the insertion allele enhances n-6 LCPUFA synthesis and may confer an adaptive advantage in South Asians because of the traditional plant-based diet practice.
