AN INSAR PERFORMANCE EVALUATION METHOD BASED ON VIRTUAL PROMINENT SCATTERERS
Authors: An‐Xi YU , Qing‐Song WANG , Zhi‐Yong MENG , Zhen DONG 
Published: June 2016

AbstractAn improved interferometric synthetic aperture radar (InSAR) performance evaluation method based on prominent scatterers (PS) is proposed to precisely assess the accuracies of the absolute/relative interferometric phase and the absolute/relative height. The critical technical defect of the conventional PS‐based method is analysed, where overvalued performance indexes are caused by higher coherence on the PS than on the ordinary ground scene. Virtual prominent scatterers (VPS) around the actual PS are introduced and treated as statistical samples when the indexes are computed. The pixel location of the VPS is estimated indirectly by utilizing the high signal to clutter ratio of the VPS and the accurate relative location between the PS and the VPS. A spaceborne InSAR signal simulation experiment is carried out to validate the new VPS‐based method. The developed method can support performance analysis, error isolation and troubleshooting in InSAR systems.
NOISE SUPPRESSION OF RECEIVER FUNCTIONS USING CURVELET TRANSFORM

Published: June 2016

AbstractSuppressing the scattering induced by the laterally heterogeneous media is important for imaging the crustal structure and its anisotropy from Receiver Functions (RFs) based on the laterally stratified model. Although the scattering can be suppressed, to some degree, with stacking technique or low‐pass filtering, these may lead to undesired waveform distortion, information loss or resolution reduction. To avoid these problems, we make use of the curvelet transform technique, which is developing rapidly in recent years, to reduce the scattering field in the RFs. Unlike exploration seismology, our major challenge comes from the spatially nonuniform sampling of RFs, caused by the spatially incomplete and uneven distribution of stations and events. To overcome these difficulties, we combine the compressed sensing theory with the curvelet‐based denoising method to realize the denoising and wavefield reconstruction, simultaneously. To verify our idea, we have tested the denoising and wavefield reconstruction with synthetic RFs and then apply our method to the observed data at one of the IRIS GSN stations and the western Sichuan array, respectively. The results show that: 1) our method is efficient in suppressing the scattering induced by the lateral heterogeneity of the crust, which leads to great improvement of the signal‐to‐noise ratio and spatial traceability of the RFs. This is valuable for the waveform imaging of the crustal structure and anisotropic parameters from the RFs; 2) the missing data caused by the event distribution can be correctly reconstructed; 3) our method can be applied to either single station or seismic array observations, but it is more efficient in single station observation than the seismic array study.
ANALYSIS AND PROCESSING OF ABNORMAL OBS DATA IN THE SOUTH CHINA SEA

Published: June 2016

AbstractProcessing and analysis of ocean bottom seismometer (OBS) data are of great importance to obtain the deep crustal structure. The deep seismic profile OBS2006‐2 was carried out in 2006 along the extinct spreading ridge of the northwest sub‐basin of the South China Sea. This survey is successful to provide high quality data whose seismic signals can be observed at the offset up to 120 km, but 2 OBSs’ recording data (OBS03 and OBS06) cannot be read correctly and were not used in later structure modeling. However, OBS data are very precious due to the high cost and arduous work. The price is more expensive when encountering severe weather during a survey. This paper is focused on reprocessing of these 2 OBSs’ data by use of the methods of checking data format, comparing signals with adjacent OBSs and resampling the data. Finally we acquire these 2 OBSs’ seismic record sections in which abundant seismic phases are clearly seen. We also obtain the seismic record section of OBS03 along the profile OBS973‐3 in the Nansha Island using the same methods above. The instrument OBS06 along the profile OBS2006‐2 and the instrument OBS03 along the profile OBS973‐3 are the same instrument confirmed by checking their logs recorded in 2006 and 2011, respectively. It demonstrates that the processing method for abnormal OBS data is reliable and effective. Then the ray‐tracing and travel‐time simulation were carried out for OBS06 and OBS03 using the interactive trial‐and‐error 2D ray‐tracing method based on the previous P‐wave velocity model of OBS2006‐2. The input of new travel‐time picks should provide stricter constraints for the deep structure beneath the profile OBS2006‐2. This research on abnormal data reprocessing does not only improve the reliability and resolution of the crustal structure, but also provide valuable experiences for OBS processing for other study areas in the future.

Published: June 2016

SummaryThis paper presents new ideas and insights towards a novel optimal control approach for power electronic converters. The so‐called stabilizing or Lyapunov‐based control paradigm is adopted, which is well known in the area of energy‐based control of power electronic converters, in which the control law takes a nonlinear state‐feedback form parameterized by a positive scalar λ. The first contribution is the extension to an optimal Lyapunov‐based control paradigm involving the specification of the optimal value for the parameter λ in a typical optimal control setting. The second contribution is the extension to more flexible optimal switching‐gain control laws, where the optimal switching surfaces are parameterized by a number of positive scalars λj. Systematic derivation of gradient information to apply gradient‐descent algorithms is provided. The proposed techniques are numerically evaluated using the exact switched model of a DC–DC boost converter. Copyright © 2016 John Wiley & Sons, Ltd.

AbstractMaternal deprivation (MD) for 24 hr during the neonatal period impairs body weight gain in adolescent and adult rats. It has been previously shown that maternally deprived rats consume less standard and carbohydrate‐rich diets. Because neuropeptide Y (NPY) is implicated in feeding behavior, we assessed, prospectively, the effects of maternal deprivation, imposed on postnatal days (PND) 3 (DEP3) or 11 (DEP11), on physical development (snout‐anal length and body weight gain, measured once a week) and food intake (assessed daily, during the rest and active phases, from PND 23 to PND 51); NPY‐immunoreactivity (NPY‐ir) in the arcuate nucleus of the hypothalamus was evaluated in male (at PND 52) and female rats in estrous (at PND 53–60). DEP3 and DEP11 male and female adolescents were smaller, lighter, and ate less during the active phase, than their CTL counterparts. This change in food intake was accompanied by reduced NPY‐ir in the arcuate nucleus of the hypothalamus. The present results indicate that maternal deprivation had a negative impact on the physical development and feeding behavior of adolescent rats that may be explained by reduced hypothalamic NPY production.
Ten‐year responses of ground‐dwelling spiders to retention harvest in the boreal forest

Published: June 2016

AbstractThe Ecosystem Management Emulating Natural Disturbances (EMEND) project tests the hypothesis that varying levels of green tree retention maintain and retain forest biodiversity better than conventional clear‐cutting. We studied epigaeic spiders to assess biodiversity changes 2, 5, and 10 yr following a range of partial retention harvests (clear‐cut, 10–75% retention) and unharvested controls in four boreal mixedwood cover types. A total of 56 371 adult spiders representing 220 species was collected using pitfall traps. Lasting effects on forest structure were proportional to harvest intensity. These changes strongly influenced spider richness, abundance, and species composition, as well as assemblage recovery. Distinctive assemblages were associated with disturbance level, especially with partial harvests (≤50% retention), and these were dominated by open‐habitat species even 10 yr after harvest. Assemblages were more similar to those of controls in the highest (75%) retention treatment, but significant recovery toward the structure of pre‐disturbance assemblages was not detected for any prescription in any cover type. Although early responses to retention harvest suggested positive effects on spider assemblages, these are better explained as lag effects after harvest because assemblages were less similar to those of unharvested controls 5 yr post‐harvest, and only minor recovery was observed 10 yr following harvest. Retention of forest biodiversity decreased over time, especially in conifer stands and the lower (10–50%) retention treatments. Overall, retention harvests retained biodiversity and promoted landscape heterogeneity somewhat better than clear‐cutting; however, there was a clear gradient of response and no retention “threshold” for conservation can be recommended on the basis of our data. Furthermore, results suggest that retention harvest prescriptions should be adjusted for cover type. We show that low retention ameliorated impacts in broadleaved forests characteristic of earlier stages in mixedwood succession, but only higher retention was associated with less impact in successionally older conifer forests. Although these short‐term responses (10 yr) of spider assemblages support use of retention harvests, understanding the true conservation merit of these practices, relative to conventional approaches, requires evaluation over longer time scales, with work more focused on recovery of biodiversity than on its preservation after harvest.

Published: June 2016

AbstractA novel voltammetric sensor was used for the determination of curcumin by using cadmium oxide nanoparticles‐ionic liquid (1,3‐dipropylimidazolium bromide as a binder) modified carbon paste electrode (CdO‐IL‐MCPE). At pH 7.0 as an optimum electrochemical condition, the oxidation signals for curcumin and vitamin B9 are separated at ca. 0.41 and 0.73 V respectively; facilitating fast and sensitive analysis of curcumin in presence of vitamin B9. The oxidation signal of curcumin represented a linear relationship with the concentration of curcumin (R2=0.9981) in the range of 0.2–320.0 µM, with a detection limit of 0.08 µM.
Determining CLOU Reaction Kinetics for Combined Oxygen Carriers—Discussing the Experimental Methods
Authors: Leion Henrik , Zhan Xiang , Frick Volkmar 
Published: June 2016

AbstractCombined oxides, primarily manganese based, have shown great potential as oxygen carriers, as they often have oxygen uncoupling properties at relevant temperatures. These oxygen carriers could be a good alternative to copper‐based materials. But in order to scale up or model the chemical‐looping with oxygen uncoupling (CLOU) process reliable oxygen carrier kinetics is needed. The general approach to determine oxygen carrier kinetics is to use thermogravimetric analysis (TGA). However, due to the nature of combined oxygen carriers the conventional approach might not be possible. The objective of this work is to explain and point out the limitations of the conventional way of using TGA for CLOU kinetics. Experiments from three different oxygen carriers, a perovskite, a manganese ore, and a manganese‐silica oxide, are used in order to illustrate the difficulties and spur new thinking in the field.

Abstract

Bees are exposed in their environment to contaminants that can weaken the colony and contribute to bee declines. Monoterpenoid-based preparations can be introduced into hives to control the parasitic mite Varroa destructor. The long-term effects of monoterpenoids are poorly investigated. Olfactory conditioning of the proboscis extension reflex (PER) has been used to evaluate the impact of stressors on cognitive functions of the honeybee such as learning and memory. The authors tested the PER to odorants on bees after exposure to monoterpenoids in hives. Octopamine receptors, transient receptor potential–like (TRPL), and γ-aminobutyric acid channels are thought to play a critical role in the memory of food experience. Gene expression levels of Amoa1, Rdl, and trpl were evaluated in parallel in the bee brain because these genes code for the cellular targets of monoterpenoids and some pesticides and neural circuits of memory require their expression. The miticide impaired the PER to odors in the 3 wk following treatment. Short-term and long-term olfactory memories were improved months after introduction of the monoterpenoids into the beehives. Chronic exposure to the miticide had significant effects on Amoa1, Rdl, and trpl gene expressions and modified seasonal changes in the expression of these genes in the brain. The decrease of expression of these genes in winter could partly explain the improvement of memory. The present study has led to new insights into alternative treatments, especially on their effects on memory and expression of selected genes involved in this cognitive function.

3‐D quasi proportional fairness scheduling in relay‐assisted multicell LTE‐A downlink
Authors: Ahmed Irfan 
Published: June 2016

AbstractThis paper presents a three‐dimensional (3‐D: space‐time‐frequency) quasi proportional fairness (QPF)‐based radio resource allocation and interference coordination scheme in multicell long‐term evolution‐advanced downlink. We formulate the resource allocation and interference coordination problem as a QPF‐based utility maximisation problem, wherein, QPF reduces the complexity compared with the conventional proportional fairness. Interference has been minimised through time, frequency and space domain resource allocation. The proposed 3‐D scheme utilises two time slots for intercell interference management, spatial position‐based frequency resource allocation for intracell interference mitigation, and frequency domain orthogonality across user equipment (UE) and relays for inter‐UE and UE‐relays interference management. It has been shown that the relaxed non‐convex primal problem and the dual problem have zero duality gap under the time‐sharing and tolerable interference constraints. The relaxed optimal problem has been solved through the Lagrange dual method. Simulation results show the efficacy of the proposed 3‐D scheme compared with the recently presented three slots time domain interference coordination with round robin and proportional fairness time domain interference coordination schemes. It has been observed that the proposed heuristic 3D with equal power scheme exhibits same performance as the heuristic 3D with water‐filling power allocation and retains the desired optimal level for more than 60% of the average users' throughput.

Published: June 2016

SummaryAn experimental investigation has been carried out for the burning of plywood cribs in a compartment under different ventilation conditions and two different crib patterns. A total of four experiments were conducted. Of them, three experiments were performed: the burning of regular crib pattern for 0%, 10%, and 100% compartment door opening. The fourth experiment was conducted for the staggered crib pattern with 100% door opening. Several measurements were made during experiments that include the flame temperature, ceiling temperature, total heat flux, outgoing gas temperatures, and heat release rate to investigate the burning characteristics and compartment environment. The rate of increase of heat release rate during growth period for staggered pattern crib was 11.5 kW/min, whereas for regular pattern crib, it was 8 kW/min. However, the peak heat release rate was only 15 kW higher as compared with that of the regular pattern crib. Increasing the ventilation to 10% and 100% has resulted in increase in the heat release rate by 61.6% and 77.4%, respectively. The compartment gas temperature and the total heat flux were highest for 10% door opening, whereas no significant changes were observed in flame temperatures with different ventilation conditions as well as crib pattern.

ABSTRACTBackgroundThe anterolateral thigh (ALT) free flap is one of the most commonly used donor sites in head and neck reconstruction, however, it is not typically considered when an osseous component is needed.MethodsSoft tissue harvests, cadaveric study, and retrospective analysis of a series of 10 patients undergoing angiography were performed to assess vascular supply to the femoral cortex. In 6 patients, corticocancellous split‐femur was incorporated into the ALT to reconstruct bony defects of the head and neck.ResultsThere is a consistent blood supply to the femur from the lateral femoral circumflex artery both intraoperatively and on angiography. No fractures or orthopedic injuries have been seen to date. None of the patients had complications of bone harvest, such as deep vein thrombosis or pulmonary embolism.ConclusionThe ALT osteomyocutaneous (ALTO) flap has consistent vascular anatomy to the femoral cortex. This flap provides additional corticocancellous bone and overlying vastus intermedius muscle for the reconstruction of complex craniofacial defects. © 2016 Wiley Periodicals, Inc.
