Filarial infection influences mosquito behaviour and fecundity
Authors: Gleave Katherine , Cook Darren , Taylor Mark J. , Reimer Lisa J.
Published: October 2016

Understanding vector-parasite interactions is increasingly important as we move towards the endpoint goals set by the Global Programme for the Elimination of Lymphatic Filariasis (GPELF), as interaction dynamics may change with reduced transmission pressure. Elimination models used to predict programmatic endpoints include parameters for vector-specific transmission dynamics, despite the fact that our knowledge of the host-seeking behaviour of filariasis infected mosquitoes is lacking. We observed a dynamic, stage-specific and density dependent change in Aedes aegypti behaviour towards host cues when exposed to Brugia malayi filarial parasites. Infected mosquitoes exhibited reduced activation and flight towards a host during the period of larval development (L1/L2), transitioning to a 5 fold increase in activation and flight towards a host when infective stage larvae (L3) were present (p < 0.001). In uninfected control mosquitoes, we observed a reduction in convergence towards a host during the same period. Furthermore, this behaviour was density dependent with non-activated mosquitoes harbouring a greater burden of L1 and L2 larvae while activated mosquitoes harboured a greater number of L3 (p < 0.001). Reductions in fecundity were also density-dependent, and extended to mosquitoes that were exposed to microfilariae but did not support larval development.

Published: October 2016

Goats (Capra hircus) are one of the oldest livestock domesticated species, and have been used for their milk, meat, hair and skins over much of the world. Detection of selection footprints in genomic regions can provide potential insights for understanding the genetic mechanism of specific phenotypic traits and better guide in animal breeding. The study presented here has generated 192.747G raw data and identified more than 5.03 million single-nucleotide polymorphisms (SNPs) and 334,151 Indels (insertions and deletions). In addition, we identified 155 and 294 candidate regions harboring 86 and 97 genes based on allele frequency differences in Dazu black goats (DBG) and Inner Mongolia cashmere goats (IMCG), respectively. Populations differentiation reflected by Fst values detected 368 putative selective sweep regions including 164 genes. The top 1% regions of both low heterozygosity and high genetic differentiation contained 239 (135 genes) and 176 (106 genes) candidate regions in DBG and IMCG, respectively. These genes were related to reproductive and productive traits, such as “neurohypophyseal hormone activity” and “adipocytokine signaling pathway”. These findings may be conducive to molecular breeding and the long-term preservation of the valuable genetic resources for this species.

We studied the electronic and nuclear dynamics of I-containing organic molecules induced by intense hard X-ray pulses at the XFEL facility SACLA in Japan. The interaction with the intense XFEL pulse causes absorption of multiple X-ray photons by the iodine atom, which results in the creation of many electronic vacancies (positive charges) via the sequential electronic relaxation in the iodine, followed by intramolecular charge redistribution. In a previous study we investigated the subsequent fragmentation by Coulomb explosion of the simplest I-substituted hydrocarbon, iodomethane (CH3I). We carried out three-dimensional momentum correlation measurements of the atomic ions created via Coulomb explosion of the molecule and found that a classical Coulomb explosion model including charge evolution (CCE-CE model), which accounts for the concerted dynamics of nuclear motion and charge creation/charge redistribution, reproduces well the observed momentum correlation maps of fragment ions emitted after XFEL irradiation. Then we extended the study to 5-iodouracil (C4H3IN2O2, 5-IU), which is a more complex molecule of biological relevance, and confirmed that, in both CH3I and 5-IU, the charge build-up takes about 10 fs, while the charge is redistributed among atoms within only a few fs. We also adopted a self-consistent charge density-functional based tight-binding (SCC-DFTB) method to treat the fragmentations of highly charged 5-IU ions created by XFEL pulses. Our SCC-DFTB modeling reproduces well the experimental and CCE-CE results. We have also investigated the influence of the nuclear dynamics on the charge redistribution (charge transfer) using nonadiabatic quantum-mechanical molecular dynamics (NAQMD) simulation. The time scale of the charge transfer from the iodine atomic site to the uracil ring induced by nuclear motion turned out to be only ∼5 fs, indicating that, besides the molecular Auger decay in which molecular orbitals delocalized over the iodine site and the uracil ring are involved, the nuclear dynamics also play a role for ultrafast charge redistribution. The present study illustrates that the CCE-CE model as well as the SCC-DFTB method can be used for reconstructing the positions of atoms in motion, in combination with the momentum correlation measurement of the atomic ions created via XFEL-induced Coulomb explosion of molecules.

RDH in BCS images based on block edge pixel separation
Authors: Zheng Hongying , Yang Ying , Xiao Di , He Jie
Published: October 2016

By block compressed sensing (BCS), the image can be compressed and encrypted simultaneously. A novel reversible data hiding (RDH) method is proposed to embed additional data into the BCS encrypted images. In the proposed method, based on the image block edge pixel separation, every block can be used for data embedding through a special measurement flipping. After decryption, considering the correlation of natural images, the fluctuation function can be used to find out the flipped block and realise the data extraction and image recovery. Experiments show that the proposed method can outperform the existing RDH method in BCS images.
Backoff scheme for crowded Bluetooth low energy networks
Authors: Kim Jinbae , Han Kijun
Published: October 2016

Bluetooth low energy (BLE) has received much attention from researchers as one of the prominent solutions for short‐range communication. The applications of BLE are growing rapidly and there are many issues to be resolved for establishing the deployment of it. Practically, BLE devices may experience a lot of collisions during discovery process due to contention among devices, particularly in a crowded environment. With an increasing number of BLE devices, discovery latency and energy consumption rise exponentially, which could degrade the quality of service required by user applications. In this study, the authors propose an enhanced discovery mechanism by employing a backoff strategy for BLE devices to reduce collisions during advertisement process. Through experimental and mathematical analysis, the proposed mechanism has shown its effectiveness in terms of discovery latency and energy consumption in crowded BLE networks.
Symbol‐multicast mutual coding for massive MIMO broadcasting
Authors: Elmusrati Mohammed S.
Published: October 2016

New transmit mutual coding for multiple input multiple output (MIMO) broadcasting is proposed. The proposed coding is based on wireless transmission over symbol multicasting to independent and uncoordinated terminals in the downlink. The motivation of proposing symbol‐multicast is the fact that in digital communication the transmission is based on a finite alphabet set of symbols. Therefore, it would be possible to multicast symbols to receivers with multi‐content broadcasting. In this technique, it has been shown that the required transmit power budget becomes independent of the number of served terminals in the downlink. In other words, any number of downlink terminals could be supported with finite power budget at the transmitter. Furthermore and under the same concept, a new system configuration for a single link (point‐to‐point) communication has been presented. With this configuration, it is possible to achieve any data rate under fixed transmit power budget.
Refined instrumental variable parameter estimation of continuous‐time Box–Jenkins models from irregularly sampled data
Authors: Chen Fengwei , Garnier Hugues , Gilson Marion , C. Agüero Juan , Liu Tao
Published: October 2016

This study investigates the estimation of continuous‐time Box–Jenkins model parameters from irregularly sampled data. The Box–Jenkins structure has been successful in describing systems subject to coloured noise, since it contains two sub‐models that feature the characteristics of both plant and noise systems. Based on plant‐noise model decomposition, a two‐step iterative procedure is proposed to solve the estimation problem, which consists of an instrumental variable method for the plant model and a prediction error method for the noise model. The proposed method is of low complexity and shows good estimation robustness and accuracy. Implementation issues are discussed to improve the computational efficiency. Numerical examples are presented to demonstrate the effectiveness of the proposed method.

Authors: Khooban Mohammad Hassan , Vafamand Navid , Niknam Taher , Dragicevic Tomislav , Blaabjerg Frede
Published: October 2016

Electric vehicles (EVs) play a significant role in different applications, such as commuter vehicles and short distance transport applications. This study presents a new structure of model‐predictive control based on the Takagi‐Sugeno fuzzy model, linear matrix inequalities, and a non‐quadratic Lyapunov function for the speed control of EVs including time‐delay states and parameter uncertainty. Experimental data, using the Federal Test Procedure (FTP‐75), is applied to test the performance and robustness of the suggested controller in the presence of time‐varying parameters. Besides, a comparison is made between the results of the suggested robust strategy and those obtained from some of the most recent studies on the same topic, to assess the efficiency of the suggested controller. Finally, the experimental results based on a TMS320F28335 DSP are performed on a direct current motor. Simulation and experimental results demonstrate the flawless performance of the suggested controller and the fast and accurate tracking of the EV speed to its set‐point.
Island partition of distribution network with microgrid based on the energy at risk
Authors: Jingxiang Zhao , Huanna Niu , Xiaoxue Zhang
Published: October 2016

An evaluation method of the power supply capacity based on the energy of risk is proposed. This method meets the need of island partition for power recovery after a fault occurring in distribution network. The multi‐objective island partition model of the distribution system with microgrid is proposed. Three objective functions are considered in this model. They are the maximum weighted sum of the load power recovery, the minimum island numbers, and the comprehensive confidence as much as possible. The uncertainty of output power in microgrid is counted based on the relation between output power and confidence. The comprehensive optimum plan is obtained by comparing the objective satisfaction degree distance of the three schemes. Finally, the results of the samples demonstrate the validity of the new model and method.

The increasing penetration of small‐scale renewable power sources into the passive distribution networks brings direct deteriorated impacts on operation of microgrids due to the lack of inertia and damping property, e.g. unexpected voltage rise, increased fault level. To this end, this study presents a novel virtual synchronous generator (VSG) based multi‐loop control solution aiming to efficiently manage the embedded inverter‐based renewable distributed generators (DGs) in a plug‐and‐play fashion. With such multi‐loop control structure, the virtual flux oriented control is adopted to avoid the harmonic interference and guarantee accurate control of vector orientation process in the U/I closed‐loop feedback based vector control. The VSG based control is able to obtain timely current response and carry out static error free tracking control of output voltage. The pre‐synchronising control aligned to the outer loop to ensure smooth transition from island to grid‐connected mode is also studied. The proposed control solution is assessed through a set of simulation experiments in a microgrid for both island and grid‐connected scenarios, and the numerical result confirms its technical benefits.
Edge patch image‐based morphological profiles for classification of multispectral and hyperspectral data

Morphological profiles (MPs) are efficiently exploited for modelling the geometrical features of structures in a scene. They increase the discriminability between different classes. The degree of processing of images depends on the geometrical structure and shape of the used structure element (SE) in the transformation. Since the geometric structures of an image are not the same in the whole image, the use of a fixed shape for SE may not be so efficient. Thus, it is proposed to extract an edge patch image‐based morphological profile (EPIMP), which considers SEs with different shapes for different areas of image. The used SE in each patch of image is corresponding to the shape (i.e. edge image) of that patch. The proposed method is experimented on both multispectral and hyperspectral images and the obtained results show that the proposed method is much more efficient than the conventional MPs. Moreover, the experiments show the superiority of EPIMP compared with some state‐of‐the‐art spectral‐spatial classification methods such as generalised composite kernel, multiple feature learning, weighted joint collaborative representation and multiple‐structure‐element non‐linear multiple kernel learning.
Evaluation of unintentional modulation for pulse compression signals based on spectrum asymmetry

Specific emitter identification has attracted much attention of researchers in recent decades. This technology distinguishes different emitters by exploiting the unintentional modulation (UIM) contained in the signal. Heretofore, evaluation of UIM for pulse compression signals had not been properly solved, since previous evaluating results generally rely heavily on intentional modulation, and cannot solely and sufficiently describe the characteristics of UIM. In this study, the authors propose a novel feature extraction method which can naturally suppress intentional modulation, and meanwhile characterise the UIM. The proposed method utilises the facts that spectrum symmetry is an intrinsic and widespread property of modulated signals; and this symmetry will break when the UIM arises. By properly evaluating the spectrum asymmetry, the frequency‐domain asymmetry distribution feature is derived. Experiments on real‐world data demonstrate that the proposed feature outperforms conventional features in dealing with pulse compression signals. This study offers an effective way to extract UIM features from modulated signals, thus having broad applications to modern radar emitters.
Current sharing in parallel connected boost converters

Parallel connection of converter modules results in generation of higher output current. Improper current sharing takes place if parameters of two converter modules are different. This study proposes a new current‐sharing scheme for parallel connected boost converters. This current‐sharing scheme control converter output by proper selection of transistor switch current. In this case, converter duty ratio is not adjusted directly. The adjustment of converter duty ratio depends on inductor current, capacitor voltage and power input voltage of converter. Stability of the proposed current‐sharing scheme is increased by adding artificial ramp to transistor switch current. The effects of adding artificial ramp are analysed and discussed. The proposed current‐sharing scheme is compared with existing current‐sharing scheme whose converter output is regulated by direct choice of duty ratio. The proposed system is implemented in real time using PIC16F877A. Simulation and experimental results verify the effectiveness of the proposed current‐sharing scheme.

Le contentieux camerounais devant les instances sportives internationales
Authors: Dikoume François Claude
Published: October 2016

Le sport est tellement règlementé que, au sein de chaque structure sportive il se trouve des commissions ou des organes juridictionnels chargés de régler les litiges sportifs qui sont devenus trop récurrents ; ainsi, chaque association sportive, chaque fédération nationale ou internationale comprend en son sein une entité juridictionnelle chargée de sanctionner ses membres à partir des règles qu'elle a elle-même élaborée et qui les régissent devenant du coup juge et partie donc, en violation du principe de la séparation des pouvoirs si chère à Montesquieu. Face à ce constat, le Comité International Olympique (CIO) a décidé de créer en 1984 une juridiction neutre, indépendante, le Tribunal Arbitral du Sport dont le siège est à Lausanne en Suisse ; celui-ci est chargé de trancher en dernier ressort des litiges sportifs en rendant des sentences qui sont sans appel. Le CIO a aussi fait créer au niveau des Comités Nationaux Olympiques, des tribunaux arbitraux du sport dont la compétence se limite au niveau des Etats. Les sentences prises par ces derniers tribunaux ne peuvent être attaquées qu'au TAS à Lausanne en Suisse.

Les acteurs du sport depuis lors, utilisent donc les voies de recours au niveau international soit vers les fédérations sportives internationales ou encore et surtout vers le TAS qui s'occupe des litiges de toutes les disciplines sportives. Il est question ici de faire un inventaire casuistique descriptif non exhaustif des requêtes contentieuses camerounaises portées devant les diverses instances sportives internationales ; ceci permettra de questionner l'esprit processuel et la qualité technique de leurs réclamations juridiques en matière sportive.
L'impact de la « démocratie sportive » sur le « Service public du sport en Afrique et par ricochet au Cameroun »
Authors: Dikoume François Claude , Jabea Claude Bekombo
Published: October 2016

Cet article s'attache à démontrer que la posture d'étatisation du sport en Afrique ayant cour depuis les années d'indépendance a subi des mutations considérables grâce à l'évolution de l'histoire du monde. Par ailleurs, aucun des acteurs du mouvement sportif ne peut se targuer de pouvoir gérer l'entièreté de son domaine tout seul. Les rôles des uns et des autres sont désormais bien définis au Cameroun en particulier, grâce à la loi n∘ 2011/018 du 15 juillet 2011 relative à l'organisation et à la promotion des activités physiques et sportives et les textes subséquents pris au fur à mesure à divers niveaux de responsabilité. Ainsi par exemple :

la gestion des équipes nationales relèvent désormais presque exclusivement des fédérations sportives nationales ;

une fédération sportive nationale ne peut plus être juge et partie en ce qui concerne les litiges d'ordre sportif (y compris le contentieux électoral) en son sein.

Il est question de faire une analyse succincte des orientations, transformations et évolutions de cette étatisation et des méthodes antidémocratiques du sport en Afrique, afin d'en tirer les nouvelles tendances que les Etats africains mettent en place.

Total occlusion of a coronary artery for more than 3 months is defined as chronic total occlusion (CTO). The goal of this study was to develop a risk score in predicting failure or success during attempted percutaneous coronary intervention (PCI) of CTO lesions using antegrade approach.

This study was based on retrospective analyses of clinical and angiographic characteristics of CTO lesions that were assessed between February 2012 and February 2014. Success rate was defined as passing through occlusion with successful stent deployment using an antegrade approach.

A total of 188 patients were studied. Mean ± SD age was 59 ± 9 years. Failure rate was 33%. In a stepwise multivariate regression analysis, bridging collaterals (OR = 6.7, CI = 1.97–23.17, score = 2), absence of stump (OR = 5.8, CI = 1.95–17.9, score = 2), presence of calcification (OR = 3.21, CI = 1.46–7.07, score = 1), presence of bending (OR = 2.8, CI = 1.28–6.10, score = 1), presence of near side branch (OR = 2.7, CI = 1.08–6.57, score = 1), and absence of retrograde filling (OR = 2.5, CI = 1.03–6.17, score = 1) were independent predictors of PCI failure. A score of 7 or more was associated with 100% failure rate whereas a score of 2 or less was associated with over 80% success rate.

Most factors associated with failure of CTO-PCI are related to lesion characteristics. A new risk score (range 0–8) is developed to predict CTO-PCI success or failure rate during antegrade approach as a guide before attempting PCI of CTO lesions.

Background There have been studies trying to characterize Fibromuscular Dysplasia (FMD); however, most of them are based in mainly non-Hispanic sample. The objective of this study is to better understand the epidemiology and clinical characteristics of craniocervical FMD in the Hispanic population.

Methods We retrospectively reviewed the cerebral angiograms performed in our center in a period of 3.5 years under any indication looking for angiographic patterns of FMD. Exclusion criteria consisted of cases in which the first angiogram was done when the patients were younger than 18 years. Patients were subdivided based on those with FMD and those without it for baseline characteristics and were looked for any associations. We further compared the same baseline characteristics among Hispanic FMD and non-Hispanic FMD population. A chart review was conducted looking for clinical features and vascular events.

Results We analyzed 448 angiograms among patients younger than 18 years. We identified 47 patients with evidence of FMD involving the cervical arteries and 401 patients without FMD. Of the 47 patients with FMD in our neuroendovascular registry, we found that 76.6% were women and 57.4% were Hispanics. There was no statistical significant difference when comparing the variables across ethnicities, except history of cigarette smoking and dyslipidemia. The most common associated supra-aortic arterial lesions seen in the FMD group were intracranial aneurysm and arterial dissections. We then used same variables to compare Hispanic FMD with non-Hispanic FMD. We have found that there has been a positive association of cigarette smoking and dyslipidemia with FMD (p ≤ 0.05).

Conclusion Our study suggests that FMD affecting the carotid and vertebral arteries has similar demographic pattern across ethnicities in the United States. In Hispanics, the disease appears to have a predilection for women and history of cigarette smoking. Intracranial aneurysm and arterial dissection were the most commonly associated arterial lesions.
Metal-on-Metal Total Hip Arthroplasty Associated with Adverse Local Tissue Reaction and Pseudoaneurysm of the Superior Gluteal Artery: A Case Report and Literature Review
Authors: Shah Amit , Botchu Rajesh , Dunlop David , Davies A. , James Steven
Published: October 2016

Adverse local tissue reaction (ALTR) and pseudoaneurysm formation are rare but known complications following metal-on-metal hip total hip arthroplasty (THA). We report the first known case in the English literature of a concurrent unilateral ALTR and pseudoaneurysm of the superior gluteal artery in the same patient. Following minimal rise in serum metal ions, an ultrasound of the right hip demonstrated an avascular solid/cystic lesion anterolaterally in keeping with an ALTR. More posterolaterally, a second discrete thick-walled cystic lesion was identified. Doppler interrogation demonstrated a “yin yang” pattern suggestive of a pseudoaneurysm. Magnetic resonance imaging confirmed the presence of an anterolateral periarticular lesion with a second discrete lesion within the gluteus medius. Subsequent computed tomography angiography confirmed the presence of arterial contrast blush within the posterior gluteal lesion adjacent to the superior gluteal artery. The patient remains asymptomatic and is being managed conservatively. We review the imaging characteristics of ALTR and pseudoaneurysm occurring post-THA. When a complex solid/cystic lesion is encountered in a patient with a THA, radiologists must ensure that the lesion is interrogated with color Doppler to confidently distinguish a pseudotumor from a pseudoaneurysm. This information is vital to the surgeon to avoid unexpected hemorrhage if revision joint replacement surgery is being contemplated.
