Quasi‐duality between SS and SP topologies of basic electric‐field coupling wireless power transfer system
Authors: Ishihara M. , Umetani K. , Umegami H. , Hiraki E. , Yamamoto M.
Published: October 2016

Series–series (SS) topology and series–parallel (SP) topology of the electric‐field coupling wireless power transfer system are widely utilised for practical applications. However, selecting the appropriate circuit topology, which maximise the output power by design optimisation, is often difficult, because these circuit topologies are generally analysed using different circuit models. This difficulty by analysing novel equivalent circuits for SS and SP topologies is addressed. As a result, the output power of SP topology is found to be approximated by that in SS topology with transformed load impedance. This result can offer a simple strategy for topology selection as well as design optimisation.
Improved BP decoder for polar codes based on a modified kernel matrix
Authors: Sha Jin , Liu Jingbo , Wang Zhongfeng
Published: October 2016

Since the polar code was discovered by Arikan, many decoding methods have been proposed, one of which is the belief propagation (BP) decoding. Its inherent high parallel level makes it suitable for high‐speed applications. A novel BP decoder based on a modified three‐by‐three kernel matrix is proposed. The corresponding decoding algorithm and frozen bits selection method are presented. The numerical results show that it has a similar error correcting capability compared with the original polar BP decoder. More importantly, the message memory requirement can be reduced from O(N log2 N) to O(N log3 N), and the decoding delay can be reduced accordingly.
Traffic sign recognition based on weighted ELM and AdaBoost
Authors: Xu Yan , Wang Quanwei , Wei Zhenyu , Ma Shuo
Published: October 2016

A novel multiclass AdaBoost‐based extreme learning machine (ELM) ensemble algorithm is proposed, in which the weighted ELM is selected as the basic weak classifier because of its much faster learning speed and much better generalisation performance than traditional support vector machines. AdaBoost acts as an ensemble learning method of a number of weighted ELMs. Then, an ensemble strong classifier is constructed by the weighted majority vote of all the weighted ELMs. Compared with the existing ELM methods, the proposed algorithm solves the problem of how to train the weighted samples by ELM in multiclass classification directly. Experiments on the German Traffic Sign Recognition Benchmark database demonstrate that the proposed algorithm can achieve a high recognition accuracy of 99.12% with a relatively lower computational complexity than many state‐of‐the‐art algorithms.
Uplink optimal power allocation for heterogeneous multiuser SIMO SC‐FDMA networks
Authors: Ahmad Ayaz , Khan Muhammad Toaha Raza , Kaleem Zeeshan
Published: October 2016

Power allocation techniques for heterogeneous orthogonal frequency division multiple access networks have been well studied. However, due to the different structure of single carrier frequency division multiple access (SC‐FDMA), these techniques are not applicable to networks employing SC‐FDMA. Optimal uplink power allocation in multiuser heterogeneous single‐input–multiple‐output (SIMO) SC‐FDMA cellular networks is considered. Users’ sum‐rate maximisation problem with per‐user transmit power constraint is formulated which is a non‐linear non‐convex problem. This problem is converted to convex optimisation problem and optimal power allocation scheme is derived. Simulations results demonstrate the performance gain of the optimal scheme over the equal power allocation scheme.
Compact and independently‐design tri‐band bandpass filter with bandwidth and return loss control
Authors: Lu Di , Barker Nicolas Scott , Tang Xiao H.
Published: October 2016

A compact tri‐band bandpass filter with high controllability is proposed using two multipath λ/4 resonator‐loaded resonators (MRLRs). Separated electric and magnetic coupling (SEMC) is applied into the filter, which introduces multiple transmission zeros (TZs) and enables each bandwidth to be separately controllable. In addition, both the return loss control and centre frequency (CF) control are implemented by changing the physical dimension of MRLRs. Owing to the usage of SEMC, three TZs can be, respectively, allocated either below or above the associated passbands. Moreover, the third passband can be far away from the first passband, e.g. 1.57/5.8 GHz (f1/3.7f1), when each passband is independently designed. A filter example operating at 1.57/3.5/5.8 GHz (GPS/WiMAX/WLAN) with a size of 0.08λg × 0.14λg is designed and fabricated. Good agreement between simulation and measurement is achieved to validate its performance.

Authors: González‐Domínguez M. , Bao D. , Dadín S. , Cuiñas I. , Sánchez M.G.
Published: October 2016

Planning emerging radio systems, as vehicle‐to‐vehicle or vehicle to infrastructure links, needs deep knowledge on the electromagnetic behaviour of the different materials involved. This Letter describes a system for measuring in‐situ reflection coefficients. Besides, it gives data related to asphalt and concrete, in both wet and dry conditions, in a band from 5.8 to 6.0 GHz. Normal incidence reflection coefficients resulted to be similar in magnitude for both materials in dry conditions, and they experiment an increase of 65% after soaking the pavement. This indicates the strong influence of moisture on the electromagnetic behaviour of common road surfaces.

Authors: Chen Y.‐H. , Tseng Y.‐H.
Published: October 2016

Cost‐effective two‐dimensional (2D) discrete cosine transform (DCT) and inverse DCT architectures capable of supporting multiple standards of MPEG, H.264 and VC‐1 are presented. The proposed core utilises a 1D core and a transposed memory to achieve a low cost design. Multi‐level factor share is implemented in conjunction with distributed arithmetic in a system to enable the sharing of the coefficient matrix circuit in order to reduce hardware costs. The proposed approach employs a time‐distribution scheme to enable the simultaneous processing of the first and second dimensions to enhance throughput. A high efficiency of this approach was verified by fabricating a test chip using the TSMC 0.18 μm CMOS process. The architecture has an operating frequency of 200 MHz, and throughput of 800 M‐pixels/s with a gate count of 44.5 K.

It shows that the non‐contact Doppler radar technique can provide an effective approach to monitor driver drowsiness.
Strictly non‐blocking three‐quarter crossbar switch with simple switch control
Authors: Obara H.
Published: October 2016

A component‐efficient design for parallel optical crossbar switches, which utilises the idle ports as extra input or output ports, is described for the first time. It is observed that conventional parallel crossbar switches composed of 2 × 2 basic switch elements have a significant number of unused internal routes between the idle ports. Two distinctive types of parallel crossbar switches with augmented input and output ports are introduced to yield a switch‐element count of 3N2/4 + 3N, where N is the switch size. The first type of switch is unidirectional and requires rearrangements. The second is bidirectional and strictly non‐blocking and have a switch control complexity of O(1).
Duty‐ratio feedforward controller design for single‐stage flyback CCM inverter
Authors: Kim H. , Kim M.
Published: October 2016

The transfer function of the flyback continuous conduction mode (CCM) inverter has a right‐half‐plane (RHP) zero that may severely degrade the control performance. If the conventional proportional–integral controller is applied, its control gain is limited by the existence of RHP zero and the inverter suffers from output current distortion. The value of the nominal duty has been used as a feedforward controller to eliminate the effect of disturbances and reduce the burden of the feedback controller. However, the conventional nominal duty performed poorly when it was utilised as a feedforward controller in flyback CCM inverter. A new nominal duty is proposed for single‐stage flyback CCM inverter. Its output tracking performance is compared with that of the conventional nominal duty.
Performance analysis of power line communication systems with diversity combining under correlated lognormal fading and Nakagami noise
Authors: Abou‐Rjeily Chadi
Published: October 2016

In this study, the authors evaluate the bit error rate (BER) performance of multichannel power line communication (PLC) systems under lognormal fading and Nakagami‐m background noise. The information signal propagates over two parallel, but correlated channels while maximum ratio combining and equal gain combining are implemented at the receiver side. By appropriately approximating the tail of the probability density function of a single Nakagami‐m noise term and of the weighted sum of two Nakagami‐m noise terms, they derive accurate expressions of the BER. They prove that single‐channel and multichannel PLC systems both benefit from an infinite diversity order and that this quantity increases logarithmically with the signal‐to‐noise ratio. In this case, the advantage of the diversity combining techniques resides in their impact on the average energy of the fading gain; a quantity that they derive analytically by applying the lognormal‐sum approximation.

Finally, two numerical examples are provided to support the theoretical findings and to testify the effectiveness and usefulness of the algorithm.
Intelligent wind power smoothing control with BESS
Authors: Lin Faa‐Jeng , Chiang Hsuang‐Chang , Chang Jin‐Kuan , Chang Yung‐Ruei
Published: October 2016

An intelligent wind power smoothing control using recurrent fuzzy neural network (RFNN) is proposed in this study. First, the modeling of wind power generator and the designed battery energy storage system (BESS) are introduced. The BESS is consisted of a bidirectional interleaved DC/DC converter and a 3‐arm 3‐level inverter. Then, the network structure of the RFNN and its online learning algorithms are described in detail. Moreover, actual wind data is adopted as the input to the designed wind power generator model. Furthermore, the three‐phase output currents of the wind power generator are converted to dq‐axis current components. The resulted q‐axis current is the input of the RFNN power smoothing control and the output is a gentle wind power curve to achieve the effect of wind power smoothing. The difference of the actual wind power and smoothed power is supplied by the BESS. The minimum energy capacity of the BESS with a small fluctuation of the grid power can be achieved by the RFNN power smoothing control. A digital signal processor (DSP) based BESS is built using two TMS320F28335. From the experimental results of various wind variation sceneries, the effectiveness of the proposed intelligent wind power smoothing control is verified.
Experimental analysis of impact of maximum power point tracking methods on energy efficiency for small‐scale wind energy conversion system
Authors: Liu Hongliang , Locment Fabrice , Sechilariu Manuela
Published: October 2016

The power control of small‐scale wind energy conversion system is usually limited by the sluggish mechanical dynamic. Aiming at highlighting this phenomenon, this article introduces a small‐scale wind energy conversion system using the permanent magnet synchronous machine as generator to validate different combinations of control strategy resulting from four different maximum power point tracking (MPPT) methods with hysteresis control: one indirect MPPT method based on a look‐up table and three direct methods based on perturb and observe relationship. Following two ideal wind speed profiles, a real rapid wind speed profile and using a test bench emulating a small‐scale wind turbine, the MPPT methods are compared and analysed based on experimental results. The indirect method operates with the best MPPT performances for all three wind speed profiles while requiring accurate knowledge of the controlled system. The direct methods operate with low MPPT performance under rapid variation of wind speed and the superiority of variable step size is not significant since the dynamic process of the perturbation strongly weakens the effect of MPPT algorithm.
Decoupled controller for single‐phase grid connected rooftop PV systems to improve voltage profile in residential distribution systems
Authors: Mishra Sukumar , Mishra Yateendra
Published: October 2016

Unity power factor injection from single‐phase photovoltaics (PVs) located towards the end of a residential feeder leads to voltage rise problems. Also, unbalanced current injection due to variable solar insolation results in voltage unbalancing and makes the situation worst. A decoupled controller for a single‐phase PV inverter is proposed to improve the voltage profile of the distribution feeders. The proposed controller consists of the following components: voltage regulator (to control the amount of reactive power injection), outer voltage control loop (slow controller to set the reference for the inner current loop), inner current control loop (to control the PV inverters) and modified second‐order generalised integrator (to generate fundamental frequency). A sample distribution systems consisting of several PVs located in all three phases and a three‐phase induction motor load is considered. The real‐time hardware‐in‐the‐loop simulations are performed to test the efficacy of the proposed controller scheme. Results show the improvement in voltage regulation of different buses.
Multichannel GMTI techniques to enhance integration of temporal signal energy for improved target detection
Authors: Paulus Audrey S. , Melvin William L. , Williams Douglas B.
Published: October 2016

Improvements in target detection are typically achieved by increasing the signal‐to‐interference‐plus‐noise ratio (SINR) of the received signal. For a small radar platform with power and aperture constraints, increases in SINR must come through temporal integration. Two techniques are presented here for enhancing the integration of temporal signal energy to improve detection of weak, slow‐moving targets over conventional methods. Both techniques involve modifications to pre‐Doppler space‐time adaptive processing (STAP), a reduced‐dimension STAP method that is implementable in real‐time on a power‐constrained platform. The two modifications include (i) development of an alternative pre‐Doppler temporal weighting method, based on linear prediction, to increase the SINR of the pre‐Doppler temporal output signal and (ii) development of an extended dwell temporal processing (EDTP) algorithm to integrate temporal signal energy collected over a long dwell. The EDTP algorithm is based on frequency domain analysis of the extended dwell time signal; the detection decision exploits the differences in the distribution of signal energy and noise energy over an extended dwell. EDTP algorithm performance is superior to traditional temporal processing methods in many practical scenarios: the EDTP algorithm detection rate is three times the detection rate of non‐coherent integration for very low‐velocity, low‐SNR targets.
Two‐dimensional potential, electric field and drain current model of source pocket hetero gate dielectric triple work function tunnel field‐effect transistor
Authors: Sharma Dheeraj , Raad Bhagwan Ram , Yadav Dharmendra Singh , Kondekar Pravin , Nigam Kaushal
Published: October 2016

Low ON current and conduction for the negative gate‐to‐source voltage are the major drawbacks of the steep subthreshold slope tunnel field‐effect transistor (TFET). Low work function on the source side of gate contact, high‐κ gate dielectric and highly doped layer (delta doping) helps to enhance the ON current of the device. Whereas, low work function of gate electrode on the drain side and low‐κ gate dielectric is used to eliminate the problem of conduction for the negative gate‐to‐source voltage. In the same concern, an analytical model for potential distribution of tri metal hetero gate dielectric delta doped TFET is developed by solving the two‐dimensional (2D) Poisson's equation. Moreover, the extraction of electric field is performed by the developed potential model. However, model of drain current for the device is based on the Kane's band‐to‐band tunnelling generation rate. Finally, the verification of the developed model is performed with the 2D technology computer aided design ATLAS simulation results.
Infection following Anterior Cruciate Ligament Reconstruction: An Analysis of 6,389 Cases
Authors: Westermann Robert , Duchman Kyle , Gao Yubo , Pugely Andrew , Hettrich Carolyn , Amendola Ned , Wolf Brian , Anthony Chris
Published: October 2016

Infection following anterior cruciate ligament reconstruction (ACLR) is rare. Previous authors have concluded that diabetes, tobacco use, and previous knee surgery may influence infection rates following ACLR. The purpose of this study was to identify a cohort of patients undergoing ACLR and define (1) the incidence of infection after ACLR from a large multicenter database and (2) the risk factors for infection after ACLR. We identified patients undergoing elective ACLRs in the American College of Surgeons National Surgical Quality Improvement Program database between 2007 and 2013. The primary outcome was any surgical site infection within 30 days of surgery. We performed univariate and multivariate analyses comparing infected and noninfected cases to identify risk factors for infection. In total, 6,398 ACLRs were available for analysis of which 39 (0.61%) were diagnosed with a postoperative infection. Univariate analysis identified preoperative dyspnea, low hematocrit, operative time > 1 hour, and hospital admission following surgery as predictors of postoperative infection. Diabetes, tobacco use, age, and body mass index (BMI) were not associated with infection (p > 0.05). After multivariate analysis, the only independent predictor of postoperative infection was hospital admission following surgery (odds ratio, 2.67; 95% confidence interval, 1.02–6.96; p = 0.04). Hospital admission following surgery was associated with an increased incidence of infection in this large, multicenter cohort. Smoking, elevated BMI, and diabetes did not increase the risk infection in the present study. Surgeons should optimize outpatient operating systems and practices to aid in same-day discharges following ACLR.
Biomechanical Comparison of Five Posterior Cruciate Ligament Reconstruction Techniques
Authors: Milles Jeffrey , Pfeiffer Ferris , Stannard James , Smith Patrick , Kfuri Mauricio , Cook James , Nuelle Clayton
Published: October 2016

No surgical technique recreates native posterior cruciate ligament (PCL) biomechanics. We compared the biomechanics of five different PCL reconstruction techniques versus the native PCL. Cadaveric knees (n = 20) were randomly assigned to one of five reconstruction techniques: Single bundle all-inside arthroscopic inlay, single bundle all-inside suspensory fixation, single bundle arthroscopic-assisted open onlay (SB-ONL), double bundle arthroscopic-assisted open inlay (DB-INL), and double bundle all-inside suspensory fixation (DB-SUSP). Each specimen was potted and connected to a servo-hydraulic load frame for testing in three conditions: PCL intact, PCL deficient, and PCL reconstructed. Testing consisted of a posterior force up to 100 N at a rate of 1 N/s at four knee flexion angles: 10, 30, 60, and 90 degrees. Three material properties were measured under each condition: load to 5 mm displacement, maximal displacement, and stiffness. Data were normalized to the native PCL, compared across techniques, compared with all PCL-intact knees and to all PCL-deficient knees using one-way analysis of variance. For load to 5 mm displacement, intact knees required significantly (p < 0.03) more load at 30 degrees of flexion than all reconstructions except the DB-SUSP. At 60 degrees of flexion, intact required significantly (p < 0.01) more load than all others except the SB-ONL. At 90 degrees, intact, SB-ONL, DB-INL, and DB-SUSP required significantly more load (p < 0.05). Maximal displacement testing showed the intact to have significantly (p < 0.02) less laxity than all others except the DB-INL and DB-SUSP at 60 degrees. At 90 degrees the intact showed significantly (p < 0.01) less laxity than all others except the DB-SUSP. The intact was significantly stiffer than all others at 30 degrees (p < 0.03) and 60 degrees (p < 0.01). Finally, the intact was significantly (p < 0.05) stiffer than all others except the DB-SUSP at 90 degrees. No technique matched the exact properties of the native PCL, but the double bundle reconstructions more closely recreated the native biomechanics immediately after implantation, with the DB-SUSP coming closest to the native ligament. This study contributes new data for consideration in PCL reconstruction technique choice.

Published: October 2016

Performance of bismuth Hall sensors developed for the ITER steady state magnetic diagnostic was investigated for high magnetic fields in the range ±7 T. Response of the sensors to the magnetic field was found to be nonlinear particularly within the range ±1 T. Significant contribution of the planar Hall effect to the sensors output voltage causing undesirable cross field sensitivity was identified. It was demonstrated that this effect can be minimized by the optimization of the sensor geometry and alignment with the magnetic field and by the application of “current-spinning technique.”
Thermal conduction in Si and SiGe phononic crystals explained by phonon mean free path spectrum
Authors: Nomura Masahiro , Nakagawa Junki , Sawano Kentarou , Maire Jeremie , Volz Sebastian
Published: October 2016

Thermal phonon transport in single-crystalline Si, amorphous SiGe, and poly-SiGe nanostructures was investigated experimentally at room temperature. The characteristic length dependence of thermal conductivity was compared across these three materials by changing the shortest distance between the circular holes of phononic crystals formed in the membranes. The dependences clearly differ for these materials, and these differences can be explained by the thermal phonon mean free path spectra of the three materials. Nanostructuring has a larger impact on thermal conductivity reduction when the characteristic length is comparable to that in the region where the thermal phonon mean free path spectrum is dense. The results suggest that thermal phonon mean free path spectra can be estimated qualitatively by thermal conductivity measurements with characteristic length sweeps.

(KDP) solutions by using a newly developed device that combines electrostatic levitation with Raman and X-ray scattering. Our study reveals two interesting phenomena. One is an existence of two different solution states, that is, low-concentration KDP solution (LCS) and high-concentration KDP solution (HCS). The other is an emergence of different crystallization paths that depend on the degree of supersaturation: (

) LCS to HCS to a metastable KDP crystal (monoclinic structure) to stable KDP crystal. This is a direct in situ observation of multiple pathways of nucleation in aqueous solution.
Evolutionary consequences of behavioral diversity
Authors: Stewart Alexander J. , Parsons Todd L. , Plotkin Joshua B.
Published: October 2016

Significance

Access to a diversity of behavioral choices makes social dynamics rich and difficult to analyze. Individuals are rarely constrained to a binary choice between “cooperate” or “defect,” as many theoretical treatments assume. Here we use game theory to ask what social behaviors will emerge in populations as the number of behavioral choices grows. We show that simple strategies, where players do not vary their behavior much at all, can nonetheless be successful, and that access to a broader range of behavioral choices can cause a population to evolve toward lower levels of cooperation. Finally, we show that access to greater choice in rock–paper–scissors games inevitably leads to behavioral diversity, with players using strategies that make use of all possible choices.
Using seafaring simulations and shortest-hop trajectories to model the prehistoric colonization of Remote Oceania
Authors: Montenegro Álvaro , Callaghan Richard T. , Fitzpatrick Scott M.
Published: October 2016

Significance

The colonization of Remote Oceania between ∼3400 and 800 B.P.—from multiple origin points and across hundreds or thousands of kilometers of open ocean—represents some of the most impressive population dispersals on Earth. For decades, scholars have sought to explain when and how these occurred. Here we show that seafaring simulation techniques coupled with sophisticated analyses of climatic data, including the role of El Niño Southern Oscillation events and island distribution on ancient voyaging, are critical comparative tools for understanding the variables—culturally, technologically, and environmentally—that structured movement across the world’s largest ocean. These data also pinpoint likely departure points for ancient Pacific Islanders that in some cases support or negate current archaeological and other lines of evidence.

Significance

Insect pests represent a major constraint that reduces crop yield and quality globally. Host plant resistance is often used as a key tactic to control insect pests, but is frequently overcome by newly emerged insect populations. In nature, plants have developed various strategies for sustainable defense. In this work, we isolated a brown planthopper-resistance gene,BPH9, and show that alleles of this gene locus have been widely used in rice breeding and saved rice production from massive brown planthopper (BPH) damage. Allelic diversity in this gene locus has provided resistance to rice against different BPH populations. Manipulating allelic diversity of the gene may provide a strategy for developing resistant varieties to cope with evolving insect populations with new virulence variation.

Significance

Inflammatory breast cancer (IBC) is defined clinically and pathologically. Dermal lymphatic invasion is typical but is neither necessary nor sufficient for diagnosis; sentinel lymph node biopsy is contraindicated, challenging multidisciplinary management with upfront chemotherapy, surgery, and postoperative radiotherapy. Here we applied a ligand-directed “theranostic” (a combination of therapeutic and diagnostic) enabling platform to target IBC based on adeno-associated virus/phage (AAVP)-
Herpes simplex
virus thymidine kinase type-1 (
HSVtk
) particles displaying ligands to cell surface-associated 78-kD glucose-regulated protein (GRP78). In a suite of preclinical models and human tumor samples, we show simultaneous noninvasive molecular serial PET/CT imaging and targeted suicide transgene therapy. This study shows that a tumor-specific promoter, human
GRP78
(
hGRP78
), can drive the expression of an imaging/suicide transgene in IBC and aggressive breast cancer in vivo.
Lutein, a carotenoid, suppresses osteoclastic bone resorption and stimulates bone formation in cultures

Published: October 2016

Lutein, a member of the xanthophyll family of carotenoids, suppressed IL-1-induced osteoclast differentiation and bone resorption. The survival of mature osteoclasts was also suppressed by lutein in cultures. When lutein was added to the cultures of osteoblasts, lutein enhanced the formation of mineralized bone nodules by elevating BMP2 expression and inhibiting sclerostin expression. Lutein may be beneficial for bone health.

Motivation

Most computational approaches for the analysis of omics data in the context of interaction networks have very long running times, provide single or partial, often heuristic, solutions and/or contain user-tuneable parameters.

Results

We introduce local enrichment analysis (LEAN) for the identification of dysregulated subnetworks from genome-wide omics datasets. By substituting the common subnetwork model with a simpler local subnetwork model, LEAN allows exact, parameter-free, efficient and exhaustive identification of local subnetworks that are statistically dysregulated, and directly implicates single genes for follow-up experiments.

Evaluation on simulated and biological data suggests that LEAN generally detects dysregulated subnetworks better, and reflects biological similarity between experiments more clearly than standard approaches. A strong signal for the local subnetwork around Von Willebrand Factor (VWF), a gene which showed no change on the mRNA level, was identified by LEAN in transcriptome data in the context of the genetic disease Cerebral Cavernous Malformations (CCM). This signal was experimentally found to correspond to an unexpected strong cellular effect on the VWF protein. LEAN can be used to pinpoint statistically significant local subnetworks in any genome-scale dataset.

Motivation

Large high-throughput screening (HTS) efforts are widely used in drug development and chemical toxicity screening. Wide use and integration of these data can benefit from an efficient, transparent and reproducible data pipeline. Summary: The tcpl R package and its associated MySQL database provide a generalized platform for efficiently storing, normalizing and dose-response modeling of large high-throughput and high-content chemical screening data. The novel dose-response modeling algorithm has been tested against millions of diverse dose-response series, and robustly fits data with outliers and cytotoxicity-related signal loss.
